Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Vale: "If we can help Arbiter...?"
  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."
  —Members of Osiris discuss their mission priorities
 
Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Vale: "If we can help Arbiter...?"
  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."
  —Members of Osiris discuss their mission priorities
 
Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack
 
Locke observing a Type-25 Spirit taking off
 
On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis
 
  Main article: Battle of Genesis
 
  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission

  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Vale: "If we can help Arbiter...?"
  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Vale: "If we can help Arbiter...?"
  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis
 
  Main article: Battle of Genesis
 
  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Vale: "If we can help Arbiter...?"
  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."
  —Members of Osiris discuss their mission priorities
 
Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard
 
  Main article: Mission to Alpha Shard

  Locke: "ONI work better alone."
  Aiken: "You are lucky ONI is even coming in an advisory capacity."
  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra
 
  Main article: Terrorist attack on Sedra City
 
  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

  "What the hell did they do to us?"
  —Jameson Locke, after observing the aftermath of the attack

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka

  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission
 
  "Nobody is putting anybody down. We don't panic like that. It's not an option."
  —Locke turning down Horrigan's suggestion to kill the prisoners who slow them down[15]
 
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
 
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]

Biography Childhood and early career
 
Born on the human colony of Jericho VII on March 15, 2529,[2] Locke was orphaned when the Covenant invaded his homeworld in 2535, being evacuated from the planet only minutes before its glassing by the Covenant. Losing everyone he had known, Locke was placed in a state orphanage with other children who had suffered a similar fate. Upon growing older, many of his compatriots enlisted in the United Nations Space Command, eager for revenge against the Covenant. However, Locke continued to blame the government for their failure to defend his homeworld and came to the conclusion that the UNSC was incapable of protecting its citizens. As a result, he became a freelance tracker and assassin. Locke's atypical behavior and questionable allegiances eventually caught the eye of the Office of Naval Intelligence, who planned to train Locke into a specific role within their organization. Seeking a greater purpose in life, Locke accepted ONI's offer to join and entered their extensive training program where he honed his skills to perfection and became one of ONI's top field operatives, serving Section Three as an Acquisitions Specialist.[1]
 
On September 26, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing the Sangheili's personal history from the UNSC's first known encounter with him on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance were to be slowed in any significant manner. This report was later accessed by John-117.[9][10] Locke offered to personally carry out the assassination, though the outbreak of the Great Schism months later and 'Vadamee's partnership with the UNSC after becoming the Arbiter led to the UNSC abandoning the plan.[11] Terrorist attack on Sedra

On February 7, 2556, Locke led an ONI team dispatched to the distant human colony Sedra to investigate terrorist activity. During the investigation Locke's unit and the Sedran Colonial Guard were forced to cooperate after Sedra City was targeted by a Sangheili Zealot terrorist wielding a powerful bioweapon. While patrolling the outskirts of Sedra City, the team spotted a Yonhet smuggler named Axl supplying the Sangheili Zealot with a stasis refrigerant. While Agent Ramos apprehended Axl, Locke, Horrigan, and Estrin pursued the Sangheili. Locke chased the Sangheili into a city access tunnel while Horrigan and the rest of the unit headed directly to the city. After a brief skirmish inside the access tunnel, the Zealot escaped into a Sedran mall with Locke pursing him. As the Sangheili prepared to activate the bioweapon, Locke jumped on top of the Zealot, disabled the alien's energy shielding, and wounded him with his M6H magnum. Locke attempted to force the Sangheili to surrender, but the Zealot jumped off a ledge and activated the bioweapon instead, killing himself in the process. Many humans throughout the city began showing signs of infection, including Locke's fellow operatives Jordan Gaines and Mason Hundley. The unit went to the Sedra Colonial Guard Hospital, where Locke and the uninfected members of his unit went through a decontamination process. After searching the freighter used to transport the bioweapon to Sedra, Locke and his unit witnessed Colonel Randall Aiken brutally interrogating Axl. However, speaking in the Covenant's trade pidgin, Locke persuaded Axl into revealing what he knew of the origins of the element used in the bioweapon.[12]
 
The unit learned of the weapon's core component—an entirely new element originating from a partly functioning segment of Installation 04 that orbited perilously close to a red giant star. The team discovered that a second tug was travelling to the shard to mine the element's deposits on the fragment. After getting the approval of Rear Admiral Goodwin, the team was forced to cooperate with the Sedran Colonial Guard to travel to the Alpha Shard, capture the smugglers who mined the element for interrogation, and destroy the deposits of the element with a HAVOK tactical nuclear weapon. However, they would be forced to complete their expedition within the sixteen hours the ring's landscape side faced away from the star; during the "day" the temperature and radiation would become unbearable. Taking a D81-LRT Condor to the partially functioning fragment, eleven ONI and Colonial Guard personnel traveled to Alpha Shard.[12] Mission to Alpha Shard

  —Locke and Aiken arguing about who should participate in operation[12]
 
During the journey through slipspace in the Condor, Locke allowed Aiken to take tactical command of the mission. Locke also revealed to Private Talitha Macer that Colonel Aiken was once a Spartan-II. Eventually, the crew arrived at their destination and landed on the Halo shard's surface. Donning their powered Nightfall armor, Locke and the other three ONI operators jumped out of the Condor at a significant height. After discovering the abandoned tug used by the smugglers, the team discovered horse tracks nearby. The team moved to the tracks' direction and come across two smugglers—Arris Le and Haisal Wari—mining the element in a cave. The smugglers attempted to escape but Locke and Horrigan quickly incapacitated and restrained the smugglers. The group began to return to the Condor for extraction; however, while the dropship was setting down, a large number of Lekgolo appeared and began to swarm over the Condor and it flew off erratically—now controlled by the Lekgolo. As more of the Lekgolo eels appeared, Locke ordered for the group to retreat as three of the Sedrans and the horses were killed. The Lekgolo, in large gestalt formations, began to pursue the group who escaped into a narrow crevice. Locke used a special appliance to holographically camouflage their position from the aliens. However, the Lekgolo quickly sensed the cloaking unit and destroyed it. As the eels closed in on the group, Arris revealed that the Lekgolo can sense active technology and movement, prompting the group to reluctantly shut down the electronics present in their equipment. Unable to detect the humans, most of the Lekgolo left the area and the nine survivors moved out of the crevice. Locke briefly stayed behind to observe a lone Lekgolo worm, before crushing it in his fist.[13] The group traversing across a river.
 
As the group continued their trek to the Condor, the team realized that only two individuals would be able to leave Alpha Shard in the smugglers' tug and that which two individuals that would leave would be decided when the mission was completed. To prevent the Lekgolo worms from tracking them, the team ditched their armor. As infighting within the group occurred, Locke promised the smugglers that they would be given a fair chance to survive if they help the team. Additionally, Locke reprimanded Horrigan after the latter suggested leaving the Sedrans and smugglers behind. Eventually, the team took a break to allow everyone to refill on fresh oxygen. The activation of the oxygen breathers alerted the Lekgolo of the team's presence. After the break, the team continued on their journey, but Sergeant Samantha Wisner dropped her breather and it rolled down a hill, activating in the progress. While Ramos went to check on her, Locke realized that the two were missing. However, the Lekgolo worms attacked Wisner and Ramos escaped just as Locke arrived. While Wisner was killed, Locke and Ramos retreated back to the group with the Lekgolo in pursuit. While attempting to escape the worms, Locke fell off a ledge and his foot became wedged under a rock. Macer arrived at his position to help him, but Locke refused and gave her his two oxygen breathers while he prepared to make a final stand against the Lekgolo. However, Macer activated one of the breathers and used it to distract the worms while she helped Locke free himself.[14] As the survivors regrouped, they hid to avoid the Lekgolo. To allow the team to escape, Horrigan pushed Haisal down a hill to be devoured by the worms. After escaping from the worms, Locke berated Horrigan for "playing god".[15]
 
While continuing on towards the Condor, Locke and Aiken conversed with each other. While Aiken told him that he was willing to die, Locke planned to survive, although he was unwilling to sacrifice members of his team. Shortly after, Horrigan desperately urged Locke to join him to escape in the smugglers' tug together. Locke maintained that he would let luck choose who would survive. While traversing alongside the edge of a cliff, Ramos secretly allowed Estrin to fall to his death after the latter refused to join Ramos in an alliance. After passing the cliff, the group took another oxygen break, but a stand-off ensured as Horrigan held Aiken at gunpoint and demanded him to give up the remaining oxygen tank. Although Locke pulled his magnum on Horrigan and ordered for him to stand down, Ramos sided with Horrigan and the two forced Locke to surrender. As Horrigan and Ramos left for the tug with Arris, the weapons, and oxygen pack, Aiken discovered the Condor nearby.[15]
 
With the nuclear ordnance recovered and the Condor having limited flight capability, Randall volunteered to detonate the warhead while Locke and Macer used the Condor to reach the tug. While Arris, Ramos, and Horrigan were consumed by the Lekgolo during their attempt to escape, Macer and Locke barely evaded the same fate. Unbeknownst to the pair, Randall's activation of the nuke drew the Lekgolo to his position, allowing the pair to escape Alpha Shard before the nuke's detonation.[16] Becoming a Spartan-IV Fireteam Osiris' formation
 
In 2556, Locke was selected to become a Spartan-IV and underwent the augmentation procedures. Leading dangerous and highly sensitive operations throughout the former Outer Colonies, Locke was often tasked with missions beyond the reach of UNSC support and has garnered an impressive and successful career in the field. As of August of 2558, Locke had participated in numerous low-profile, yet critical, operations. He participated in Operation: DELHI, a denial of material mission against insurrectionist forces on Hat Yai; Locke succeeded in destroying twenty-one special technical assets. In Operation: MAD HATTER, Locke was a part of a counter-mobility strike in a redacted location on Boundless Artifice, a Jiralhanae-controlled "forgeship". He later participated in a surveillance mission, known as Operation: EASTERN AZURE, on Kig-Yar salvage operations and mapping of slipspace routes at Arcadia in the Procyon system. Locke had also served as security for an ONI xenoarchaeological survey team at a redacted location for Operation: DAWN ECLIPSE.[2] By October of 2558, he had been assigned to lead Fireteam Osiris, comprised of Spartan-IVs Olympia Vale, Edward Buck, and Holly Tanaka. Fireteam Osiris was charged with carrying out a variety of complex missions for the UNSC Security Council and High Command.[17] Battle of Kamchatka
 
  Main article: Battle of Kamchatka
 
  "Jul 'Mdama is an opportunist, not a leader. It was only a matter of time before his version of the Covenant started to break."
  —Jameson Locke[18]
 
After several human colonies were unexpectedly attacked by mysterious Forerunner entities, Doctor Catherine Halsey contacted UNSC Infinity with information about the attacks. In response, Locke and the rest of Fireteam Osiris were tasked with rescuing Dr. Halsey from the custody of Covenant Supreme Commander Jul 'Mdama on the Forerunner world of Kamchatka.[18] Locke after assassinating 'Mdama
 
After being briefed by Captain Thomas Lasky of UNSC Infinity, the Spartans were delivered to Kamchatka via D79-TC Pelican, where they discovered the Covenant engaging their former Promethean allies. Osiris exited the Pelican dropship to free fall past battling Covenant and Promethean ships, using their armor's thrusters to control their following landing. Osiris landed on a mountainside, where the Covenant and Prometheans were currently engaged in combat and the Spartans fought their way through the terrain. While Vale eliminated Covenant forces aboard a Type-57 Phantom, Locke and the rest of Osiris battled numerous Covenant and Promethean forces on the ground. As one of the Covenant blockade runners crashed into a nearby mountain peak, Osiris regrouped and was forced to outrun the ensuring avalanche. The Spartans leaped off a cliff and slide down the mountainside, where they promptly engaged nearby Covenant forces in a valley. With 'Mdama and Halsey located in a nearby Forerunner structure, Fireteam Osiris fought their way past Covenant and Promethean forces to reach their targets' location. Although 'Mdama had a Kraken deployed to fend off the hostile forces assaulting his location, the Prometheans managed to force the walker to retreat.[18]
 
As Osiris battled their way to the structure, they arrived at 'Mdama's and Halsey's position on a balcony. While Tanaka, Vale, and Buck engaged 'Mdama's Zealot guards, Locke charged towards 'Mdama to begin engaging the Supreme Commander in close-quarters combat. After a brief fight, Locke managed to assassinate 'Mdama, and Tanaka, Vale, and Buck quickly eliminated the remaining Sangheili soldiers on the platform. With Halsey recovered, Osiris and the doctor returned to UNSC Infinity.[18] Hunt on Meridian
 
  Main article: Battle of Meridian (2558)
 
  Edward Buck: "You know, Locke… Every other Spartan… every soldier, when they hear about this… they're gonna hate us. You know that, right?"
  Jameson Locke: "You're not the only one here because of him."
  —Buck and Locke, upon being tasked with capturing Blue Team[19]
 
Upon their return to Infinity, Fireteam Osiris learned that Spartan-IIs John-117, Kelly-087, Linda-058, and Fred-104 of Blue Team traveled to the Outer Colony of Meridian—absent without leave—to investigate smart AI Cortana's location. Osiris was tasked with embarking to the recently resettled and now independent Meridian to track down Blue Team and take them back to the UNSC.[19] To prepare for the mission, Locke tasked an AI to identify weaknesses in Spartan-IIs and the MJOLNIR Mark VI.[20] Fireteam Osiris arrived at Pinnacle Station—the Meridian space elevator—via Pelican, where they descended to the moon's surface. Osiris quickly discovered that the world was also under attack from Promethean constructs and Meridian's settlers were desperately attempting to fend off the invaders. In exchange for colony leader Governor Sloan's cooperation, Osiris agreed to help defend Meridian from the Prometheans. After destroying the Prometheans that were assaulting the outpost at the space elevator's base, the Spartans began travelling to Meridian Station, the lead settlement on the moon which the Prometheans were attempting to invade. However, Sloan was reluctant to give Osiris access to the road leading to the settlement, fearing that the Prometheans would follow. However, Osiris eliminated the surrounding Prometheans and Sloan allowed the Spartans to have access to the road. At Sloan's request, Osiris aided several settlers under attack at a nearby service garage and Sloan ordered his men to give the Spartans one of the Liang Dortmund Corporation's M820 Scorpions to use against the Prometheans in exchange for their help.[19] Osiris encounters the Warden Eternal
 
After using the Scorpion to clear out the rest of the nearby Prometheans, Vale and the rest of Osiris proceeded to Meridian Station, where they discovered that Sloan was a smart AI suffering from onset rampancy. Sloan allowed the Spartans to search the settlement for clues about Blue Team's location, leading to Locke having Osiris split up to see if they could learn anything from the local settlers. After learning that Blue Team's prowler was seen traveling to the nearby Apogee Station, Fireteam Osiris boarded a transport Pelican and departed for the settlement.[21] Upon arriving at Apogee, they found the settlement under attack. Working with Meridian soldiers, Locke and the rest of the Spartans cleared out the Prometheans and discovered Blue Team's abandoned prowler. Accessing the prowler's data banks, Osiris discovered that Blue Team had traveled to the mines under the settlement. After eliminating more Prometheans throughout the mines, Osiris discovered that the Meridian settlers had found a massive Forerunner structure underneath the moon's surface. As they investigated the structure, they eventually came across the Warden Eternal, an ancilla that served as the protector of the Domain and claimed his loyalty belonged to Cortana. After refusing to allow the Spartans to pursue Blue Team, Fireteam Osiris engaged the Warden and eventually destroyed him. Advancing forward, Osiris came across a Guardian in a large, cavernous chamber. While exploring the area, Vale discovered a local slipspace translocation network throughout the cavern and noticed Blue Team using it on above platforms. Following Vale, Locke and the rest of Osiris pursued Blue Team as they advanced from platform to platform utilizing the translocation network. During the chase, Locke got ahead of the rest of his fireteam and was teleported to the same platform that Blue Team was on.[22] Locke and the Chief fighting
 
As the Spartan-IIs prepared to travel through one last teleporter to reach the Guardian, Locke ordered them to stand down. The rest of Osiris was teleported to a higher platform, as John-117 ordered his own teammates to go through the portal ahead of him. When John refused to stand down and moved to follow his team, Locke attempted to detain him, leading to a hand-to-hand combat fight between the two while the rest of Osiris watched nearby. John eventually gained the upper hand and used Locke's own armor-locking device against him. As John escaped through the portal and entered the Guardian, the massive construct began to activate and the floating platforms around Osiris began falling out of place and into the lava below. Freeing Locke, the four Spartans rushed back the way Blue Team came by traveling back to each platform via teleporter. Fireteam Osiris was just able to enter the last teleporter as its platform plummeted towards the lava, with Locke assisting Buck through the portal when the latter had nearly fallen off the platform.[22] The Spartans were teleported back to Meridian's surface, where they discovered that the colony was already well into its evacuation as settlers rushed into the moon's space elevator. As Osiris raced to the elevator to escape the ensuring damages that would be caused by the Guardian's activation, the construct rose out of the surface nearby. After fighting their way to the base of the elevator, Sloan allowed Osiris to enter. Sloan then revealed that he was warned of the Guardian's activation by Cortana, and that he intended to be a part of the future Cortana was creating for humans and AI. Osiris destroyed the remaining Prometheans nearby and, after activating it, the fireteam began ascending the space tether. On the way to the elevator terminal, while engaging more Prometheans, the Guardian sent out a shockwave that heavy damaged the elevator. The Spartans were forced to climb the elevator as the structure slowly began to fall. Just as Osiris arrived at the platform their Pelican was on, the Guardian continued to send out more frequent shockwaves that slowed the Spartans down and caused the platform they were on to collapse. Osiris barely managed to enter the dropship, with Locke having to use his armor thrusters to board the Pelican as it fell from the platform. Once Locke was aboard, the Spartans left Meridian's atmosphere as the Guardian entered slipspace and left the moon.[23] Mission to Sanghelios

  Locke: "We do. But not at the risk of missing the Guardian. Reaching Master Chief is more important."

Locke formulates a plan with the Arbiter
 
After Fireteam Osiris returned to Infinity, Lasky ordered for the fireteam—along with Commander Sarah Palmer and Halsey—to travel to the Sangheili homeworld of Sanghelios to utilize the planet's inactivate Guardian to pursue Blue Team. Vale and the rest of Osiris were taken to the planet's surface via Type-56 Lich, where they were tasked with finding Arbiter Thel 'Vadam while he was leading the Swords of Sanghelios against the invading remnants of 'Mdama's Covenant at the Elder Council Chamber in Nuusra. As Osiris engaged Covenant forces, Palmer had Mahkee 'Chava deploy two Mantises for the Spartans to utilize in clearing out the Covenant warriors at the Elder Council Chamber. Upon arriving at the chamber, Osiris battled the Covenant forces assaulting the building and fought their way inside, where they meet up with 'Vadam. With Osiris' help, the Swords of Sanghelios eliminated the Covenant forces at the Council Chamber. Moments later, 'Chava arrived in a Phantom and extracted the Arbiter and Spartans.[11] Traveling to the Swords of Sanghelios' encampment at Nuusra, Osiris worked together with Halsey, Palmer, and 'Vadam to formulate a plan to utilize the Guardian. 'Vadam, recognizing Locke as the ONI agent that had planned to assassinate him in the Covenant War, was initially reluctant to move his forces to assist the Spartans. However, when Cortana briefly shorted out all electronics at the encampment, 'Vadam agreed to work with Locke. Osiris was tasked with locating a Forerunner Constructor at one of the Guardian's nearby support stations to allow Halsey to input commands into the construct to force it to activate the Guardian.[24] Palmer flew Fireteam Osiris to the support station, but was forced to drop them off just south of the facility due to the presence of a Covenant Kraken nearby. While the Spartans provided ground support, the Swords of Sanghelios assaulted the walker from the air. While the Arbiter's flight squadrons forced the Kraken into retreat, Osiris fought their way to an ancient Sangheili temple located near the support facility. After defeating several Prometheans at the temple, the Kraken arrived at the temple, threatening Osiris' mission. As the walker neared, the Spartans boarded the Kraken and destroyed its power generator from within. Osiris fled that doomed walker and traveled into the support facility via stolen Type-54 Banshees. Once inside the station, Osiris retrieved a Constructor, but were attacked by Promethean forces. After battling their way back to an extraction point with the Constructor, a Phantom transported them back to the Swords of Sanghelios' encampment.[25] Locke prevents Buck from falling into the sea
 
With the Constructor, Halsey inputted her commands into it and the construct took off to activate the Guardian. However, the Guardian was located in the Csurdon Sea next to the city of Sunaion, the last bastion of the Covenant on Sanghelios. The Arbiter's forces regrouped and prepared to attack the city to eliminate the Covenant and give Osiris a chance to board the Guardian.[26] Traveling to Sunaion with a squadron of air vehicles, Fireteam Osiris, Arbiter 'Vadam, and several Swords of Sanghelios forces were deployed to Sunaion and engaged Covenant soldiers throughout. While the Arbiter led his forces against the Covenant directly, Osiris destroyed Covenant anti-air emplacements to allow the Arbiter's fleet to move in closer to the city. Unable to receive air support for transport to the Guardian, Osiris accessed Sunaion's undercity to travel to its location. When the Constructor activated the Guardian, Promethean forces arrived at the battle and began engaging the Spartans, as well as the Arbiter and his forces. When the Guardian began rising out of the sea nearby and started to activate its shockwaves, the buildings around the Spartans were ripped apart. As the Spartans moved to safety, they regrouped with the Arbiter as he was engaging Promethean forces. The five battled the onslaught of Prometheans, which were soon led by the Warden Eternal, now utilizing another physical body. After a lengthy engagement, the five destroyed the Warden and the nearby Prometheans just as the Guardian prepared to leave. While the Arbiter remained behind to finish eliminating Covenant and Promethean forces, Palmer and Halsey picked up Osiris in the Pelican and flew towards the Guardian. A pursuing Banshee damaged the dropship, though Palmer was still able to drop Osiris off on the Guardian's surface just as it entered slipspace and left Sanghelios.[27] Conflicts on Genesis

  "You're not taking the Chief..."
  —Locke disrupting Cortana's plans
 
Locke agrees to work together with Blue Team
 
Upon exiting slipspace, the Guardian arrived at the Forerunner world of Genesis, where all the other Guardians had traveled to at Cortana's demand. While the Spartans observed their new surroundings, the Guardian attempted to shake the Spartans off, forcing Vale and her team to quickly descend down the construct until they were close enough to the ground to safely jump off the Guardian. Osiris soon encountered monitor 031 Exuberant Witness, who served as caretaker of the installation. The ancilla revealed that Cortana was intending to use the Guardians to force peace across the galaxy and to wipe out those that refused, apparently trying to instill the Forerunners' Mantle of Responsibility on all species with herself and other AI—now calling themselves the Created—at its beholders. Osiris resolved to aiding Blue Team and stopping Cortana, with the help of Exuberant Witness. As the Spartans traveled to Blue Team's position at Genesis' Gateway, they encountered Covenant forces that were inadvertently brought to Genesis with the Guardians, as well as hostile Promethean forces. Osiris fought their way towards the Gateway, were they were attacked by the Warden Eternal once again but managed to defeat him. Upon arriving just outside the Gateway, Osiris came under attack from more Prometheans and several of the Warden's bodies, as they attempted to buy time for Cortana to finish her plans. After a long engagement, Osiris proved victorious and Exuberant Witness gave the Spartans access to the inside of the Gateway.[28] Locke returns to Sanghelios with John
 
Upon entering, Osiris and Exuberant Witness encountered Blue Team. While the eight Spartans agreed to work together to stop Cortana from enacting her plans, the AI suddenly teleported Blue Team to near her position.[28] Cortana ultimately placed Blue Team in a Cryptum with the intention of keeping them in stasis for ten thousand years while she initiated her plans.[29] Osiris moved to free Blue Team and, upon exiting the Gateway, witnessed the numerous Guardians entering slipspace to begin enforcing Cortana's new order. As the Spartans engaged Covenant and Promethean forces while on their way to the Cryptum, Cortana revealed that hundreds of AIs had pledged their allegiance to her, including Governor Sloan. Reaching the Cryptum, Osiris had to destroy several gravitational cores keeping the Cryptum in place. As Osiris came close to freeing Blue Team, Cortana began to taunt the Spartans in hopes of demoralizing them, but to no avail. After destroying the gravitational cores, Osiris activated a terminal to lower the Cryptum. However, Cortana suddenly pulled the Cryptum to the Guardian she was preparing to leave on. As Cortana prepared to leave, she began to disconnect herself from Genesis' systems, giving Exuberant Witness an opportunity to take full control of the planet once again. To aid the monitor, Osiris activated two nearby auxiliary power stations to help Exuberant Witness regain control of Genesis. The monitor provided the Spartans a route to Cortana's Guardian and the Cryptum, and Osiris rushed to stop their departure, pushing past the Guardian's powerful shockwaves. Locke managed to reach the relay terminal that gave Cortana control and destroyed it, reinstating full control of Genesis to Exuberant Witness. As Vale came to Locke's aid, Cortana prepared to leave the planet aboard her Guardian with the Cryptum, but Exuberant Witness sent a fleet of Constructors to take the Cryptum from the Guardian just as it entered slipspace. Once Blue Team was freed from the Cryptum, the group traveled back to Sanghelios to rendezvous with the Arbiter, Palmer, and Halsey to discuss their next move now that Cortana and other AIs were commanding numerous Guardians throughout the galaxy to enforce the Mantle of Responsibility.[5] Personality and traits Locke and Tanaka share a tender moment before departing for a mission

==Biography==
A collected and forward-thinking individual, Locke is a competent soldier who takes a professional approach to combat situations. He is a proficient leader and inspires loyalty in his subordinates, even when they do not agree with his decisions. He is generally nonconfrontational and willing to resolve conflicts through negotiation. While his ONI compatriots Estrin and Horrigan were vocal with their low opinions on the Sedran Colonial Guard, Locke was willing to put aside their disagreements for the sake of the mission. Although he is serious about his duty to protect humanity.[30] Despite impressions from Veronica Dare that Locke is "ONI to the bone,"[31] Locke is troubled by some aspects of the organization he serves under.[32]
===Early career===
Ord Casto was born on ''[[High Charity]]'' on [[2396|March 15, 2396]].<ref name="essential"/> He began his political career as a [[junior staffer]] serving in the [[Ministry of Concert]]. During his time in the Ministry, a complaint was received from an [[Unggoy]] distillers' union that claimed faulty atmospheric controls on [[Kig-Yar]] naval vessels were tainting the Unggoy's batches of [[infusion]]—recreational narcotics often enjoyed by Unggoy. Ord Casto was tasked with the dispute due to its seemingly trivial nature. However, he unearthed a conspiracy by several radical Kig-Yar [[shipmaster]]s to poison infusion resources. The Kig-Yar planned to render the Unggoy infertile, as petty revenge for the displacement of Kig-Yar nests which had led to an increase in Kig-Yar infant mortality—caused by a recent boom in Unggoy population. Although Casto recommended stiff penalties, the [[Minister of Concert]] decided to simply fine the Kig-Yar involved. Casto lodged a formal complaint, but was rebuffed by his superiors who did not wish to anger the Kig-Yar. However, the "Infusion Incident" quickly escalated into a bloody civil war known as the [[Unggoy Rebellion]] in [[2462]], bringing about the [[Ages of Conflict|39th Age of Conflict]].<ref>'''[[Halo: Contact Harvest]]''', ''pages 150-152''</ref> After the Unggoy were pacified and brought back into the Covenant, the [[Ages of Doubt|23rd Age of Doubt]] began, and Casto was promoted to Minister of [[Ministry of Fortitude|Fortitude]] shortly after.<ref>'''Halo: Contact Harvest''', ''page 156''</ref>


As the Minister of Fortitude, Ord Casto served as an exceptional politician for decades.<ref name="universe">[https://www.halowaypoint.com/en-us/universe/characters/prophet-of-truth '''Halo Waypoint''': ''Prophet of Truth'']</ref> Throughout his service in this position, Fortitude worked hard to see that [[Forerunner]] technology was evenly distributed among the member races to prevent another Age of Conflict. Fortitude was on the [[Roll of Celibates]], a list of San'Shyuum not allowed to breed due to their weak genes. This did not, however, particularly bother him.<ref>'''Halo: Contact Harvest''', ''page 264''</ref> As the Minister of Fortitude, he was fond of smoking, yet he rarely used the [[hookah tobacco]]s favored by his senior staff.<ref>'''Halo: Contact Harvest''', ''page 143''</ref>
Locke is quick to solve complicated political and tactical situations using his knowledge and intelligence.[2] Locke was able to converse with the Yonhet Axl with the alien's own language,[12] likely Yonhetian or the trade pidgin spoken within the Covenant fringe.[33]


===Rise to Hierarch===
  Help.png This section needs expansion. You can help Halopedia by expanding it.
On [[2525|January 18, 2525]], Fortitude met with the [[Ministry of Tranquility|Vice Minister of Tranquility]], [[Prophet of Regret|Lod Mron]]. The Vice Minister informed him of the massive trove of "[[Forerunner]] artifacts" that had been discovered on [[Harvest|a planet]] outside of Covenant space by ''[[Minor Transgression]]''. Tranquility planned to use these artifacts to spring himself into a position of high power, as a [[Hierarchs|Hierarch of the Covenant]], and offered the same for Fortitude. Additionally, the Vice Minister had a [[Jiralhanae]] [[Rapid Conversion|vessel]] awaiting for orders near the planet. Intrigued, Fortitude had the Vice Minister order the ship under his command to confirm the artifacts' discovery. Rather than upset the fine balance of power by allowing the [[Sangheili]] to gain the treasures, Fortitude ensured that the Jiralhanae were the ones leading the search.<ref>'''Halo: Contact Harvest''', ''pages 154-158''</ref>


In order to push the three current Hierarchs—[[Prophet of Tolerance|Tolerance]], [[Prophetess of Obligation|Obligation]], and [[Prophet of Restraint|Restraint]]—from their positions, Fortitude utilized blackmail against the Prophet of Restraint. The Vice Minister of Tranquility had shown himself as a sympathizer for those blacklisted from reproducing due to inbred genes, after being urged to do so by Fortitude who was aware that Restraint had illegitimately fathered two children. The Prophet of Restraint offered Tranquility a high position if he would adopt the children, but the scheming Prophets instead used this to their advantage, blackmailing him and forcing the Prophet to step down or have his scandalous affair made public.<ref>'''Halo: Contact Harvest''', ''page 266''</ref>

Before their coup, the Prophets visited the [[Philologist]] [[Prophet of Mercy|Hod Rumnt]], leader of the [[Asceticism|ascetic priests]] aboard the [[Forerunner Dreadnought]] and keeper of the Oracle, which was actually the long-dormant [[Mendicant Bias]], an ancient [[Artificial intelligence|AI]] that had not spoken to anyone for thousands of years.<ref>'''Halo: Contact Harvest''', ''page 271''</ref> When the Luminations of Harvest were inserted into its matrix, it suddenly reactivated and revealed that the basis of their religious institutions was in fact a misinterpretation. Not only were recently discovered humans considered equals to the Forerunners by the Oracle, but the hallowed "Reclamation" glyph in the Covenant faith actually meant "[[Reclaimer]]". They believed, erroneously, that humans were descended from the Forerunners, a fact that directly contradicted the central tenet of the Covenant religion, that none would be left behind when the Great Journey began. If humans were the chosen successors of the Forerunners — or were surviving Forerunners themselves — yet had not transcended when the Sacred Rings were last activated, then that meant that the Halos would not provide godhood to ''all'' who walked the divine path.<ref>'''Halo: Contact Harvest''', ''page 275'' (''"'The Forerunners,' the Minister whispered. 'Some were left behind.'"'')</ref> The Oracle then tried to launch the central Forerunner Dreadnought from ''[[High Charity]]'' to find and bring the humans to [[Installation 00|the Ark]]. Before it could succeed, the [[Lekgolo]] worms inside the Dreadnought short-circuited it and stopped Mendicant Bias.<ref>'''Halo: Contact Harvest''', ''pages 274-276''</ref> Fortitude, Tranquility, and the Philologist made the decision to disconnect the Oracle from the ship and decided to eradicate humanity before any of the Covenant learned that the most basic premise of their faith was false, and that [[human|"living gods"]] would probably replace the Prophets. They ascended to power, taking the names of Truth, Regret, and Mercy.<ref>'''Halo: Contact Harvest''', ''page 381''</ref> When Fortitude realized the implications of what the Oracle had told them, he and the other two Hierarchs-to-be agreed not to tell the masses of their discovery, and decided that [[Human-Covenant War|the humans must be eradicated]] once and for all before any in the Covenant could learn the truth.<ref>'''Halo: Contact Harvest''', ''page 385''</ref>
During the mission to Alpha Shard, Locke wore a set of Nightfall armor with red detailing.


The three Prophets successfully implemented their plan and became the new rulers of the Covenant. This heralded the beginning of the [[Ninth Age of Reclamation]]. Fortitude chose the name "Truth" as a reminder to himself of the truths he must never tell, and the lies he would have to spin to prevent the Covenant from fragmenting.<ref>'''Halo: Contact Harvest''', ''page 384''</ref>
After undergoing Spartan augmentation procedures Locke was issued a set of MJOLNIR Hunter armor with a Resolute visor. It is painted dark gray with red-orange highlights and light blue lighting. Additional cosmetic details on his armour include an ONI emblem on the chest piece's left breast, with the code number 00-8221-3 painted on both sides. There is an additional yellow decal on the back of the armour's helmet. His preferred loadout is a BR85N battle rifle with the M6H2 magnum.[34] Production notes Graphic Halo.png Check out our collection of quotes related to Jameson Locke on its quotes page.

===Rubble crisis===
  Agent Locke is the primary playable character in Halo 5: Guardians and is slated to appear in at least one subsequent video game.[35] He debuted in promotional art for Guardians and was later identified in the announcement trailer for Halo: The Master Chief Collection. He is properly introduced in the digital series Halo: Nightfall.[36] He is also featured in the terminals, prologue, and epilogue cinematics of Halo 2: Anniversary, setting up his story arc in Halo 5.
Around [[2535]], Truth was approached by the [[Kig-Yar]] [[Reth]], who had brought information of [[the Rubble]] and of the resident humans' desire to trade with the Kig-Yar.<ref name="cp236">'''[[Halo: The Cole Protocol]]''', ''pages 236''</ref> Realizing that the trade could be used to map the human population, Truth secretly authorized Reth to begin trading weapons which had been modified for use by the humans, then sold to the [[Insurrectionist]]s living in the Rubble. This would hopefully allow the Covenant to track the weapons, finding new human worlds to glass. The institution of the [[Cole Protocol]] hindered this, but Reth had a plan to acquire the location of [[Earth|the human homeworld]] from his human contact [[Peter Bonifacio]]. Truth, who was wishing to minimize Sangheili control on the Covenant, promised the Kig-Yar a higher position in the Covenant if the task was successfully completed.<ref>'''Halo: The Cole Protocol''', ''pages 229-231''</ref> Truth also approved of Reth's plans to construct a massive [[Unggoy]] army on the [[methane]]-rich [[moon]] of [[Metisette]] and eventually use it to attack Earth.<ref name="cp236"/>
  Mike Colter portrays Locke in Halo: Nightfall and in the Halo 2: Anniversary terminals. Colter provides the character's motion capture and character model in Halo 5: Guardians[37] while Ike Amadi provides his voice.[38] This is due to scheduling issues with Colter, who was simultaneously filming for his role as the Marvel character Luke Cage.[39]
  Locke was tentatively named "Marlowe" during the casting process of Halo: Nightfall.[40]
  Locke's unique base attributes in Halo 5: Guardians is the ability to carry one extra frag grenade and faster thruster recharge and slower stabilizer descent.[41]


All went according to plan until the uninformed Regret sent [[Shipmaster]] [[Thel 'Vadamee]] to investigate the weapons, which had made their way to [[black market]]s on ''High Charity''. Truth made his way to the [[Charybdis system]], several days after the [[Battle of Charybdis IX]], to personally rebuke Regret aboard the latter's personal cruiser—''[[Infinite Sacrifice]]''. Truth decided to leave for the Rubble alongside Regret and his fleet to either aid the Kig-Yar's efforts, or help destroy the Rubble.<ref>'''Halo: The Cole Protocol''', ''pages 285-286''</ref> Due to a failure of the humans to provide Earth's location, Reth ordered an attack on the Rubble and [[Habitat Exodus|Exodus]] [[asteroid]]s, which soon disintegrated along with Truth's plan. With the failure of the plan, Truth was about to have Thel and his soldiers executed, until Thel saved him from a [[Zhar (Sangheili)|disillusioned Sangheili Zealot]]. As a reward, Truth spared Thel on the condition that he "say nothing of what happened here".<ref>'''Halo: The Cole Protocol''', ''pages 340-342''</ref> After returning to ''High Charity'', Truth looked on the positive side, stating that they had purged possible human-sympathizing Kig-Yar and Unggoy, and because of the modified weapons, had found two more human worlds.<ref>'''Halo: The Cole Protocol''', ''pages 347-348''</ref>

===Divisive mandate===
  Locke in Halo: Nightfall.
Obsessed with the Great Journey and his personal ascension into godhood, Truth would suffer no disloyalty. Even well before the removal of the Sangheili from the [[Honor Guard]] and the Covenant's [[Great Schism]], Truth had begun to doubt the loyalty and reliability of the Sangheili, viewing them as a species splintered by heresy and derision, even amongst their own ranks. The seeds of this were placed when the then-Vice Minister of Tranquility wisely made the decision to send the Jiralhanae to [[Harvest]], and the more recent incident concerning the [[Battle of the Rubble]] only strengthened these impressions. Most damning, isolated Sangheili held secret doubts as to why the humans were being exterminated despite their stubborn resistance and bravery. They had not been offered a chance to be absorbed into the Covenant as other races had. Truth learned of these conversations from Jiralhanae spies stationed through the Covenant's fleet. 


In contrast, Truth was pleased with the Jiralhanae for their eagerness to prove their loyalty, not to mention their battle prowess had earned them a place as the protectors of the Covenant. Such blind faith and vicious enthusiasm marked them as near perfect pawns for Truth to sacrifice, without the inherent risk that the honor-bound Sangheili held.<ref name="bwu">[http://www.bungie.net/News/content.aspx?type=topnews&cid=16989 '''Bungie.net''': ''Bungie Weekly Update: 01/23/09'']</ref>

This led Truth to put his "divisive mandate" in motion. Secretly, he devised a complex scheme to eventually replace the Sangheili with the Jiralhanae as his personal guardians, as well as the primary warrior race of the Covenant. This started with subtle gestures that soon became [[Changing of the Guard|more and more drastic]], which later would ultimately culminate in the [[Great Schism]]. His plans were never made in haste; they were laid gradually and with great care.<ref name="bwu"/>

===Discovery of Earth===

The Prophet of Truth became the deciding factor in all issues for the three Prophets, representing an inequality in power that put him above the other two.<ref>'''Halo 2''', campaign level ''[[The Heretic]]''</ref><ref>'''Halo 2''', campaign level ''[[The Arbiter]]''</ref>


Some time before the Prophet of Regret's mission to Earth, Truth had managed to discover Earth's location. For him, this was an opportunity to crush his enemies—both the humans and the Sangheili—once and for all. Instead of informing the rest of the Covenant or his fellow Hierarchs of this discovery, he secretly assembled a fleet of over five hundred warships, to a command-and-control station called ''[[Unyielding Hierophant]]''. All of these forces were commanded exclusively by the Jiralhanae, making it a simple matter to turn the fleet against the Sangheili once the humans had been crushed. This plan had more immediate advantages as well; leaving the Sangheili to scour Earth in search of the most sacred Forerunner artifact in existence, the [[Installation 00|Ark]] [[Portal at Voi|portal generator]], would have placed Truth's plan upon the shoulders of a species he had already decided to cast aside.<ref name="waypoint">'''[[Halo Waypoint]]''', ''"Ten Twenty" history entry''</ref>

However, the UNSC forces discovered ''Unyielding Hierophant'' and its purpose, and a small team of [[SPARTAN-II]] supersoldiers led by [[John-117|the Master Chief]] destroyed the station, along with all but a dozen of the ships in its charge.<ref name="waypoint"/>

After the destruction of ''Unyielding Hierophant'', Truth waited in ''High Charity'' in the [[Sanctum of the Hierarchs]] for [[Tartarus]], [[Chieftain of the Jiralhanae]], to arrive with what remained of an ancient [[Forerunner Crystal]] that could manipulate time and space. He ordered the reward and secret execution of the remaining survivors from [[Operation: FIRST STRIKE]], so as not to cause panic in the Covenant by stories of how the [[Demon]]s had destroyed an entire fleet.<ref>'''[[Halo: First Strike]]''', ''pages 406-408''</ref> Knowledge of the station's ultimate goal, and its eventual destruction, were suppressed by the Prophet of Truth—the ''Unyielding Hierophant'''s original purpose has since remained a closely guarded secret, even from the rest of the Hierarchs.<ref name="waypoint"/>

===The Heretics and the new Arbiter===

[[File:H2A-TruthAndMercy.jpg|300px|thumb|Truth and Mercy preside over the trial of Thel 'Vadamee.]]
{{Quote|The Council decided to have you hung by your entrails, and your corpse paraded through the city. But ultimately, the terms of your execution are up to me.|Truth speaking to the new Arbiter, Thel 'Vadamee.}}


Thel 'Vadamee, the former [[Supreme Commander]] of the ''[[Fleet of Particular Justice]]'', was brought before the High Council to answer for his failure in protecting the holy [[Installation 04|Halo]] from its destruction at the hands of [[John-117|the Demon]]. The Council called 'Vadamee a heretic for the magnitude of his failure, and with a nod, Truth dismissed 'Vadamee from the Council Chamber, stating that when the Great Journey began the disgraced Sangheili would be left behind. 'Vadamee was later branded with the [[Mark of Shame]] by Tartarus in front of the population of High Charity. However, instead of executing 'Vadamee as the Council decided, Truth, backed by the High Prophets of Regret and Mercy, chose to make him an [[Arbiter]]. Knowing full well that the Arbiter's missions were suicide, the Council would have their corpse in the end. Truth then sent his new Arbiter against the [[Heretic]] rebellion forming on the nearby [[gas mine]] on [[Threshold]]. Despite heavy resistance from the Heretics and an unexpected incursion by [[the Flood]], the Arbiter succeeded in his task and survived.

===Occupation of Earth===
  Locke meeting with the Sangheili.
While Truth had kept the discovery of the human homeworld a secret, the Prophet of Regret managed to independently discover the location of the Portal. Eager to exploit its power, Regret quickly departed for Earth with a fleet of fifteen ships, not realizing that this planet was in fact the most heavily defended human world of all: Earth.<ref name="waypoint"/>


Soon after this, Truth learned of the Prophet of Regret's foolhardy move and sent a massive fleet, commanded by the Jiralhanae, to Earth to pick up where Regret had left off. Upon arrival at Earth, Regret's forces were outnumbered and outgunned. In mere hours, Regret was forced to retreat. Shortly thereafter, Truth's fleet arrived. <ref name="waypoint"/>

Several surviving ships from Regret's fleet were still under the command of the Sangheili.

Once the UNSC forces had been defeated in the city of New Mombasa, Truth's fleet would start uncovering the Portal, preparing it for his arrival nearly a month later.<ref name="waypoint"/><ref>'''[[Halo 3: ODST]]'''</ref>

===Punishing Regret===

{{Quote|Your haste has jeopardized the fulfillment of our Covenant, threatened our grand design.|[[Cortana]], quoting Truth's words to Regret.}}


While on [[Installation 05|Delta Halo]], Regret transmitted an apology to Truth, apologizing for his reckless attack on [[Earth]], having not anticipated a strong human presence there. Truth responded angrily, saying that it was only [[Mercy]] who had stopped Truth from publicly condemning Regret. Nevertheless, High Charity and its fleet rushed to Installation 05 and released a fleet of [[Phantom]]s full of forces to save Regret from a strike force led by John-117. His sermons were interrupted when John-117 gained entry to his inner sanctum, assassinating Regret and his Honor Guard. The rescue Phantoms were called back by Truth, and instead a [[CAS-class assault carrier|assault carrier]] destroyed the ancient building. It is probable that Truth ''allowed'' Regret to be killed, using the Demon to rid himself of Regret, and providing a long needed pretext for the replacement of the Sangheili Honor Guards.

===Locating the Sacred Icon===

{{Quote|We are, all of us, gravely concerned. The release of the Parasite was unexpected, unfortunate. But, there is no need to panic. In truth, this is a time to rejoice. A moment that all the Covenant should savor. For the Sacred Icon has been found. With it, our path is clear, our entry into the Divine Beyond guaranteed! The Great Journey is nigh! And nothing, not even the Flood, can stop it.|Truth to all of ''High Charity''}}


Defying expectations the Arbiter had found an Oracle calling itself [[343 Guilty Spark]], who had escaped the destruction of Halo. Carefully questioning the Oracle, the Prophets learned of the [[Activation Index]], which they called the Sacred Icon, required to activate a Halo ring.

Truth and Mercy then dispatched the Arbiter and many high-ranking Elites, including Rtas 'Vadumee, to collect the Index from the [[Library]] of Delta Halo, fully expecting most, if not all, of them to be killed by the Flood, and secretly ordering Tartarus and his top Brute warriors to kill any Elites that made it to the Sacred Icon. This resulted in the attempted assassination of the Arbiter, and in [[Miranda Keyes]] and [[Avery Junior Johnson|Avery Johnson]] being taken prisoner.

  Locke smashing through a wall on Sanghelios.
After Regret was killed by the Master Chief, Truth's duplicitous scheming came to full fruition. The Elite Honor Guard's failure to protect the Prophet of Regret afforded him with the final leverage needed to appoint the Brutes to the lofty position. Truth began [[Changing of the Guard|replacing]] the [[Sangheili Honor Guardsman|Elites]] with the [[Jiralhanae Honor Guardsman|Brutes]] as the Prophets' [[Honor Guard of the Covenant|protectors]]. This was a devastating blow to the Elites' honor, and they threatened to resign from the High Council in outrage. Shortly thereafter, while Truth was addressing the Covenant about the Flood, the Sacred Icon, and the [[Great Journey]], SPARTAN-117 was teleported into Truth's chamber. Forced to flee from the Demon, Truth and Mercy tried to escape to the Forerunner Dreadnought located in the city's center. On the move, Truth, knowing that there was no chance of the Sangheili stepping down peacefully, secretly ordered the genocide of the Sangheili by the Jiralhanae. Initially, the Sangheili believed that the Jiralhanae had begun an insurrection against them and the Prophets. When [[Thel 'Vadam]] informed them otherwise, the Sangheili rebelled against the Covenant completely. The [[Great Schism|Covenant Civil War]] had begun.


As the two remaining Prophets tried to escape with their human captives, a mass of [[Flood Infection Forms]] attacked them. Most were destroyed by Tartarus and his Brutes, but one leaped towards Mercy, knocking the frail Prophet off his gravity throne, and infected him through the throat. Tartarus attempted to save the old Prophet, but Truth ordered him to be left behind as a final ploy to take absolute control of the Covenant. Truth's quest for power and godhood would not be dissuaded or threatened by anyone, even his fellow Prophets.

Truth sent Tartarus to Delta Halo to activate the rings while he escaped into the Forerunner Dreadnought. When the Master Chief questioned a dying Mercy, he told the Chief that Truth was going to Earth, "To finish what we started."

===Assault on Earth===

[[File:Broadcast2.jpg|thumb|300px|A hologram of Truth in [[Voi]].]]
{{Quote|You are, all of you, vermin! Cowering in the dirt, thinking... what, I wonder? That you might escape the coming fire? ''No!'' Your world will [[Glassing|burn until its surface is but glass]]! And not even your ''[[John-117|Demon]]'' will live to creep - blackened - from its hole to mar the reflection of our passage, the culmination of our Journey. For your destruction is the will of the gods. And I? I am their instrument!|Truth making a broadcast to the humans of Earth.}}


Although Tartarus' attempt to activate Delta Halo had failed, ending in the Brute Chieftain's death, Truth was not deterred, going back to the artifact which Regret had sought. Truth departed from High Charity onboard the Forerunner Dreadnought, severing the ancient vessel from the city's power grid. Unknowingly carrying Spartan-117 onboard the ship, Truth headed for Earth, and after his fleet managed to defeat the orbital defenses, he landed the Dreadnought on the Forerunner artifact. His troops had nearly finished excavation during the four weeks since their arrival. While the digging was still in process, Truth broadcast to [[Crow's Nest|a UNSC base]], declaring that human extinction was inevitable and not even their "Demon" could stop him.

===The Ark and death===

[[File:TruthDeath-large.jpg|thumb|300px|The death of Truth.]]
{{quote|I... am... Truth! The voice of the Covenant!|Truth's last words}}


Once the artifact was fully uncovered, Truth landed his Dreadnought directly on it, while his troops set up air defenses around the perimeter. On [[2552#December|December 11]],<ref>[http://halo.xbox.com/en-us/intel/featured/video/herofortitude/bfe5038b-314a-4f17-a6be-f7613e0e3788 '''Halo Waypoint''', ''Hero-Fortitude'']</ref> the UNSC managed to break through the defenses and assaulted the Dreadnought directly. However, Truth successfully activated the artifact, opening a portal to the Ark. After getting through this portal and traveling to an activation room on the installation, he shielded himself from attack and captured [[Sergeant Major]] Johnson, a Reclaimer, to activate the rings for him. Despite the Prophet's efforts, the combined forces of the UNSC and the Elites deactivated a section of his shield and broke through, along with the newly Flood-controlled ''High Charity''. Truth's enemies closed in around him, assaulting the Citadel from all sides. In the Ark's [[Citadel]], a [[Brute Chieftain]] proceeded to beat a captive Johnson, who goaded him on. Truth ordered the Chieftain to let him live, as only a human could activate Forerunner technology. As the High Prophet tried to force Johnson to activate the ring, Commander Keyes crashed a [[D77H-TCI Pelican Dropship|Pelican]] into the control platform in hopes of rescuing Johnson, but found herself surrounded by Truth's [[Brute Bodyguard]]s.
  Locke in a desert.


As Miranda held the Brutes back with her firearms, Truth told her she that she was only delaying the inevitable. Realizing he was right, Miranda decided to kill both herself and Johnson before either could be forced to activate the installations.  However, she hesitated to kill Johnson, giving Truth the opportunity to shoot her in the back with a [[Type-25 Carbine|Brute Spiker]]. He then derisively commented to Johnson that he now understood why the Forerunners had left humanity behind: Humans were too weak and sentimental to be worthy of ascension to godhood. <ref>''[[Halo 3]]'', [[The Covenant (level)|The Covenant]]</ref> Truth forced Johnson's hand onto the control panel, activating the Halo Array.
  Render of Locke with a BR85N.


Truth's plans were derailed, however, by the appearance of [[John-117]] and [[Thel 'Vadam]], who had formed a temporary alliance with the Gravemind and its Flood. Truth's guards were overwhelmed by the surge of Flood on the bridge, and by the time John-117 and Thel reached Truth, he was already succumbing to a Flood infection form. Declaring his vengeance on a Prophet, not a parasite, the Arbiter held Truth by the throat forcing him to watch John-117 deactivate the Halo Array. Truth gave a final, defiant declaration of his holiness before being stabbed through the chest by 'Vadam's Energy Sword. The supreme leader of the Covenant was dead, and what was left of his empire crumbled away soon after.

==Personality and traits==
  Profile of Locke and Chief given with Halo merchandise to popular Halo community personalities.
[[File:HGN_Shiek_Truth.jpg|thumb|250px|Behind his collected and manipulative facade, the Prophet of Truth was torn by internal conflict over his knowledge of the very foundation of the Covenant being a lie.]]
In public, Truth displayed a calm, stoic personality. During Thel 'Vadamee's trial he expressed little or no emotion whatsoever despite the fact that Installation 04 was an irreplaceable relic. However, he was quick to become angry towards those, like his fellow Hierarch Regret, who did something foolish or reckless. If so angered, Truth was quick to dispose of his enemies, directly or through careful plotting. After arriving on Earth, Truth appeared noticeably more aggressive and impatient, possibly having grown annoyed by the "Demon" interfering in his ascent to godhood.  


Contrary to his name, Truth is very deceptive, frequently lying or covering up certain events to accomplish his goals; he was well aware of the irony of his title, reflecting upon choosing his name that he would be forced to lie for the sake of the Covenant. In an attempt to boost the Jiralhanae's popularity within the Covenant, he announced to the Covenant that it was the Brutes who found the Sacred Icon instead of the Arbiter Thel 'Vadamee. Truth also secretly ordered the killing of Thel 'Vadamee by the Brute Chieftain Tartarus, as well as the assassination of the Elite council members, knowing of the Brutes' own rivalry with the Sangheili and manipulating that rivalry to suit him. Truth also lied that the Prophet of Mercy was by his side during the Flood's assault on ''High Charity'', when in fact, Mercy had died in an attack by the Flood moments earlier. Truth had mercilessly denied him help, stating that "the Great Journey waits for no one". Prior to the Human-Covenant War, he had acknowledged that he would have to be deceitful in order to "maintain the Covenant" by claiming that the humans were trying to steal and destroy Forerunner relics, when, in fact, the Forerunner glyphs were mistranslated as "Reclamation" instead of "[[Reclaimer]]."
List of appearances


Although inspiring and charismatic, it is likely that Truth was at least partially insane. Despite being aware that humanity, not the Covenant, were the Forerunners' chosen successors, he was still fixated upon achieving godhood through the use of the Halo Rings. He seems to have rationalized this by claiming that humanity was "weak," and that the Forerunners had left them behind intentionally. Truth thus became obsessed with gaining more power for himself, to the point where he began to see himself as a god, ready to join the Forerunners that he worshipped.

Another potential possibility was that Truth was secretly aware of the Halos' purpose, and wished to fire them himself; then, having been shielded on the Halo he fired (or, alternatively, the Ark), he could have started a new age in which he ruled as one supreme god over all who survived on this Halo installation, leading him to be immortalised in the time afterwards. If this is the case, Truth lied to the entire Covenant, using the promise of the Great Journey to manipulate them into doing his bidding.
Sources


As evidenced by his desire to achieve divinity at the expense of the entire galaxy, Truth was a callous individual who disregarded the lives of all others. Truth was responsible for the Human-Covenant War and the twenty-three billion human lives lost in it, as well as the Great Schism, and the frequent betrayal of his allies. Truth also compromised the holy city of ''High Charity'' at a key moment during the Flood assault on the city, due to the Covenant civil war that he caused.

===Motivation and goals===
Categories:
As Truth allowed both the Prophet of Mercy and Prophet of Regret to die, it would seem that he wanted supreme power over the entire Covenant, not content to share amongst his fellow rulers.


After the death of the Prophet of Regret, the Prophet of Truth charged the Elites with no longer being able to guarantee their safety, and despite arguments that they could have stopped SPARTAN-117 if they had not been withdrawn due to his order, the Prophet began to set in motion a plan that was preconceived: the shifting of power within the Covenant from the Elites to the Brutes. In a sense, he "killed two birds with one stone" - one, giving himself greater power after Regret's death, and two, passing power to the more loyal Brutes before the Schism.

Though the Prophet questioned and learned from 343 Guilty Spark, the extent of his belief in the "Great Journey" is not entirely clear. As the Minister of Fortitude, he learned from the AI stationed on the Forerunner Dreadnought, Mendicant Bias, that the humans were the heirs of all the Forerunners left behind. Fortitude knew that revealing this truth to the Covenant would completely shatter the foundation of the Covenant religion, as it implied that humans, not the Covenant, were the worthy inheritors of the Forerunners. As a result, he lied and claimed that the humans had destroyed the reliquary on Harvest and declared the species to be an affront to the gods, initiating a war that would cost billions of lives for both humanity and the Covenant.

Although the Covenant's exact beliefs regarding the Great Journey are not entirely clear, this appears to contradict the notion of the Halos propelling the faithful into godhood and indicates Truth was aware of the Halos' destructive purpose. It is apparent that he sought to activate the rings while safe in the Ark to clear all of his nemeses, both Sangheili and humans alike. It is possible that after learning about the true purpose of the Halos, Truth construed the Great Journey as a means to eliminate the Covenant's enemies; with himself and his followers saved on the Ark and the rest of the galaxy purged, they would wield the so-called "godly" power promised by the Prophets for ages.

However, when Johnson asks Truth, "Can't start your own party?", Truth replies: "I admit. I need your help. But that secret dies with all the rest." This indicates that he ordered the Brutes to capture a human, but did not tell them why, supporting the idea that the Covenant at large remained oblivious to the [[Halo Array]]'s true function. He likely took advantage of the fact that the Jiralhanae are not as questioning as the Sangheili and that the promise of the Great Journey would reach them if they obeyed.

Some part of Truth's animosity towards the Sangheili may stem from the fact that both races competed in [[Sangheili-San'Shyuum war|a bloody war]] thousands upon thousands of years ago, many decades before the forming of the Covenant. Nevertheless, the Hierarch says that the Elites never really "believed in the promise of the sacred ring".

Although a description for the Prophet describes him as "deluded, possibly insane" as well as a true believer, it is noted that he has always been far less ascetic in his views, even while still the Minister of Fortitude, accepting the dogma but not usually acting in particular reverence toward it.<ref>''Halo: Contact Harvest'', page 148: "Fortitude was not as devout as other Prophets. He believed in the Great Journey, to be sure, but by vocation he was more technocrat than theologian. And yet, as the Minister rose through a pocket of less-crowded air, he couldn't help but feel a rush of spiritual invigoration as the Dreadnought's grand tripodal frame began to glimmer in the morning light."</ref> This continued later on in his career as a Hierarch, most likely because he was partially disillusioned to the Covenant religion by Mendicant Bias's revelations aboard the Forerunner Dreadnought, though not to the extent, unfortunately, that he knew that the Great Journey was a myth and that activating the Halos would destroy all sentient life in the galaxy.

All of Truth's actions can be seen as means to preserve the Covenant. He declared war on humanity in order to keep the Covenant from learning that the Great Journey was a lie, which would tear it apart.<ref>'''Halo: Contact Harvest''', ''page 384''</ref> When Sangheili came closer to finding out that the Great Journey was a lie, as with [[Sesa 'Refumee's heretic faction]], he viewed them as a threat. Seeing the Sangheili as a threat to uncovering the truth, he made plans to [[Great Schism|eject them from the Covenant]] in order to stop the truth behind the Great Journey from spreading. As a leader, keeping the Covenant alive was one of his main goals if not the highest.

*In ''[[Halo: First Strike]]'', both Truth and Tartarus are referred to as "it." Prophet, his title, is a masculine word, as opposed to "Prophetess." This was probably done simply because both individuals are non-human, whereas the rest of the book is told from the humans' viewpoint.
*The Prophet of Truth is voiced by [[Michael Wincott]] in ''Halo 2'' and by [[Terence Stamp]] in ''Halo 3''. The change was made due to the fact Wincott chose not to reprise his role in ''Halo 3''.<ref>[http://forums.bungie.org/halo/archive31.pl?read=939328 '''Halo.bungie.org''': ''Re: Post of Incorrect Logical Leaps'']</ref>
*The Prophet of Truth is the only Covenant character who has referred to John-117 as the "Master Chief" (barring Thel 'Vadam during Halo 2 Anniversary's Epilogue, as well as the Halo 5 Guardians E3 2015 demo), though several Elites at least acknowledged him as "Spartan".
*In ''Halo: Contact Harvest'' (in which Truth was still known as Fortitude), it is stated that the design of Fortitude's apartment, which narrows as it gets higher until finally tapering to a point, is not only to serve as an anti-intruder measure, but also as a personification of Fortitude's political philosophy: At the top, there is only room for one. This foreshadows Truth's later betrayal of Regret and Mercy in order to become the sole head of the Covenant.<ref>'''Halo: Contact Harvest''', ''page 154''</ref>
*The Prophet of Truth was named #60 on IGN's Top 100 Video Game Villains list.<ref>[http://www.ign.com/videogame-villains/60.html '''IGN''': ''Prophet of Truth is number 60'']</ref>
*Truth's day and month of birth was decided upon in ''Halo: The Essential Visual Guide''. It was chosen to echo "the Ides of March" account of Julius Caesar's assassination, as the Prophet of Truth was assassinated by the Arbiter.
