Jameson Locke

This article is about the ONI agent. For the Marine, see Locke (Mombasa).

"Thel 'Vadam"

Lieutenant Commander Jameson Locke is a SPARTAN-IV supersoldier and an Office of Naval Intelligence agent. He serves under ONI's Section III as an Acquisitions Specialist, his duties including the retrieval of important objects from the enemy as well as the assassination and tracking of high-profile individuals.

Childhood and early career
Born on the colony of Jericho VII, 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 UNSC, 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 freelancer 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.

On September 26th, 2552, Locke compiled a target profile report concerning Supreme Commander Thel 'Vadamee, detailing 'Vadamee's personal history from the first encounter between the UNSC and Thel on the Rubble to the glassing of Reach. Locke concluded the report by recommending the immediate termination of 'Vadamee if the Covenant advance was to be slowed in any significant manner. This report was later accessed by John-117.

Terrorist attack on Sedra
"What the hell did they do to us?"

- Locke observing the aftermath of the attack

On February 7th, 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 new 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 Gregory Ramos apprehended Axl, Locke, Michael Horrigan, and Alistair Estrin pursued the Sangheili. Locke chased after 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 Sedran 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 an alien language, Locke was able to persuade Axl into revealing what he knew of the origins of the element used in the bioweapon.

The unit learned that the core ingredient of the weapon—an all-new element—originated from partly functioning segment of Installation 04 orbiting perilously close to a red giant star. The team discovered 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 as 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 travelled to the Alpha Shard.

Mission to Alpha Shard
"Locke"

- Aiken

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, the 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.

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. 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".

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.

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.

Hunting 117
"He's gone AWOL and the UNSC want him back. I'm going to bring him home."

- Spartan Locke about his target

At some point after the mission on Alpha Shard, Locke underwent the SPARTAN-IV augmentation procedures and was assigned to lead a team of Spartans. Following the Didact's attack on Earth and MCPO John-117's disappearance, Locke was tasked with tracking down the Master Chief after several colony worlds were unexpectedly attacked. To this end, Locke met with Arbiter Thel 'Vadam and studied video recordings of the Master Chief's exploits to better learn about the legendary Spartan's history. During his meeting with the Arbiter, Locke led a fireteam of SPARTAN-IVs in a joint mission with the Swords of Sanghelios against Covenant remnant forces.

Personality and traits
"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

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, Locke is troubled by some aspects of the organization he serves under.

Locke was able to converse with the Yonhet Axl with the alien's own language, likely the trade pidgin spoken within the Covenant fringe.

Equipment
During the mission to Alpha Shard, Locke wore a set of Nightfall armor with red detailing.

After undergoing Spartan augmentation procedures Locke was issued a set of MJOLNIR Hunter armor. It is painted dark gray with red-orange highlights and light blue lighting. An ONI emblem is painted on the chest piece's left breast, with the code number 00-8221-3 painted on both sides.
