'''[[Master Chief Petty Officer]] John-117''', also known simply by his rank as the "'''Master Chief'''" or (as is common in military culture) simply as the "'''Chief'''", is a [[Spartan-II]] supersoldier of the [[UNSC Navy]]'s [[UNSC Special Forces|Special Weapons]] division. He served as one of the most important figures of the [[Human-Covenant War]]. After over thirty years of active duty, he is one of the most decorated war veterans of the [[United Nations Space Command]].

By [[2558#August|August of 2558]], John had completed two hundred and nine military operations, including one hundred and thirty-six full campaigns; more than anyone other UNSC personnel on record at the time.{{Ref/Reuse|H5GLED}} Though John has commanded nearly every [[Spartan-II]] at one time or another, the lion's share of his career has been spent as [[fireteam]] leader of [[Blue Team]]. His actions during the [[Covenant War]] earned him every major [[UNSC]] service medal and combat award, save for the [[Prisoner of War Medallion]], as well as several dozen [[civilian]] honors.{{Ref/Reuse|H5GLED}}<ref name="HTFOR28">''Halo: The Fall of Reach'', Chapter 28</ref>{{Ref/Note|As John is subordinate to Naval Special Weapons, it is unlikely that he could have earned exclusive service medals from the Army, the Marine Corps, and the Air Force. These medals may have been bestowed on behalf of the Office of Naval Intelligence in order to boost morale.}}  

John went missing after the [[Battle of Installation 00|war's final battle]] in [[2552#December|December 2552]], having stymied the threat of the Covenant, the Flood, and the Halos.<ref name="H3H">''Halo 3'', campaign level [[Halo (Halo 3 level)|Halo]]</ref> In the interbellum, John was lauded as a hero, and though he was officially declared [[missing in action|MIA]] like all Spartans,<ref name="H4P">''Halo 4'', [[Prologue]]</ref> he was ostensibly believed by the UNSC to have perished.{{Ref/Reuse|H3H}} After his recovery in [[2557#July|July 2557]], he played a key role in the [[Post-Covenant War conflicts|conflict]] between the UNSC and the [[Ur-Didact|Didact]]'s [[Promethean#Mechanical Prometheans|Promethean]] forces and a [[Jul 'Mdama's Covenant|new "Covenant" faction]], beginning on the [[shield world]] [[Requiem]]. This culminated in an [[New Phoenix Incident|attack on Earth]] and the Didact's temporary defeat, as well as the apparent loss of Cortana.{{Ref/Reuse|midnight}} John subsequently reunited with Blue Team and with their help, [[Skirmish on Installation 03|vanquished the Didact]] a second time. John and his Spartan compatriots went on to participate in numerous new missions for over a year.

Within the military he is most commonly identified as "SPARTAN-117" or the phonetic callsign "Sierra 117". As with all Spartans, John was regarded by the Covenant as a "[[Covenant religion#Demons|Demon]]". However, John specifically was known as "''the'' Demon", an epithet he earned after the destruction of Installation 04, though [[Fleet of Retribution|allied Sangheili]] soon came to address him as "Spartan". The Didact and the [[Warden Eternal]] addressed John and his Spartan teammates as Warriors or [[Warrior-Servant]]s.{{Ref/Reuse|HE10}}<ref name="H5GR">''[[Halo 5: Guardians]]'', ''[[Reunion]]''</ref>

Over the ensuing months, John and his Spartans were rapidly deployed on a number of battlefronts, taking part in the [[Battle of Alpha Corvi II]] later in 2525 and a [[boarding|boarding action]] against the frigate ''[[Radiant Arrow]]'' before being assigned as instrumental parts of [[Operation: SILENT STORM]] in early [[2526]]. During the operation, John worked for the first time alongside enlisted UNSC personnel of the [[21st Space Assault Battalion]]. Throughout the operation, John was a key participant in the battles of [[Battle of Seoba|Seoba]], [[Battle over Etalan|Etalan]], and finally a massive [[Attack on Zhoist]]. In this final engagement of SILENT STORM, John led one of the only offensive actions of the war into Covenant space, deploying on the Covenant world of [[Zhoist]] to destroy the [[Ring of Mighty Abundance]], a key logistics base. The mission saw John attain the rank of [[Master Chief Petty Officer]] and formed a friendship with [[Avery Johnson]].<ref>''[[Halo: Silent Storm]]''</ref>

[[File:Corridor Attack.jpg|thumb|right|250px|John-117 leading Fred-104 and Kelly-087 during Operation: WARM BLANKET.]]

In July of 2552, the [[Covenant]] [[Fleet of Valiant Prudence]] invaded Reach, with knowledge of this engagement kept secret from John and the rest of the Spartans as to not compromise the planned [[Operation: RED FLAG]] - a mission with the objective of capturing a {{Class|CAS|assault carrier}} or {{Class|CSO|supercarrier}} with intent to use it to transport Spartans to the Covenant capitol and capture a [[Hierarchs|Hierarch]], hopefully forcing an end to the war. The ''Valiant'' arrived at Reach in August, at which point he was debriefed on the Sigma Octanus battle and recovered artifact. A few weeks later, John was summoned, along with all other available Spartans, for a briefing on RED FLAG.  

Upon the ship's arrival at [[Halo]] [[Installation 04]], it soon became clear that the {{Class|Halcyon|light cruiser}} {{UNSCShip|Pillar of Autumn}} had been followed through slipspace by a dozen Covenant ships. These vessels engaged the ''Autumn'' and sent several capture parties to [[Boarding|board]] the ship. [[Captain (Navy)|Captain]] [[Jacob Keyes]] ordered John to be woken from cryosleep, and tasked him with ensuring the escape of [[Cortana]] while he crash-landed the ''Pillar of Autumn'' on the then-unidentified ringworld. John escaped the ship and [[Landing on Installation 04|landed]] on the structure via [[SKT-9 Bumblebee]] lifeboat.{{Ref/Level|CE|[[The Pillar of Autumn (Halo: Combat Evolved level)|The Pillar of Autumn]]}}

[[File:Fight on Ascendant Justice.png|right|thumb|250px|John-117 fighting aboard ''Ascendant Justice''.]]

John succeeded in locating some of his fellow Spartans on Reach, along with [[Vice Admiral]] [[Danforth Whitcomb]] and Dr. Catherine Halsey. They returned to the [[DDS-class carrier|carrier]] and linked it with the damaged [[Paris-class heavy frigate|UNSC frigate]] ''[[UNSC Gettysburg|Gettysburg]]''. Before traveling to Earth, they decided to head into the [[Eridanus system]] where they discovered that the [[Insurrectionist#Eridanus cell|rebel]] base, [[Eridanus Secundus]], was still intact, now led by [[Jacob Jiles|Governor Jacob Jiles]]. After receiving some repairs, they were forced to abandon the rebels in the face of a Covenant assault, and made their way toward the Covenant refit-and-repair station, ''[[Unyielding Hierophant]]'', where [[Truth's fleet|an enormous fleet]] was poised to invade Earth.

Vice Admiral Whitcomb and Lieutenant Haverson piloted the ''Ascendant Justice'' straight into the ''Unyielding Hierophant''. Whitcomb discussed the battles of the [[Battle of the Alamo|Alamo]] and [[Battle of Thermopylae|Thermopylae]] briefly with John, then prepared to fight the Covenant off while the ''Unyielding Hierophant''<nowiki>'</nowiki>s fusion reactor detonated. Each of the five hundred Covenant ships maneuvered next to the ''Ascendant Justice'', desperately to recover a Forerunner navigation crystal. The Admiral and the Lieutenant were both killed when the station's fusion reactor exploded, annihilating 486 ships of the Covenant fleet, leaving only around a dozen intact. The paltry survivors of the [[Prophet of Truth]]'s fleet would later be committed to reinforce the Prophet of Regret's botched attack against [[New Mombasa]] on Earth. John left after witnessing Whitcomb's and Haverson's sacrifice, and arrived at Earth with the last members of his team, Linda, Will, and Fred, as well as Johnson and Cortana. They also brought with them news of the Covenant's imminent invasion.{{Ref/Reuse|HFS36}}

====Battle of Earth====

[[File:H2A-John&marines.jpg|thumb|250px|right|The Master Chief on the streets of Old Mombasa.]]

{{Main|Battle of Earth}}

Aboard ''[[Cairo Station (station)|Cairo Station]]'', John received a suit of [[MJOLNIR Powered Assault Armor/Mark VI|Mark VI MJOLNIR]] and attended an award ceremony with [[Lieutenant Commander]] [[Miranda Keyes]] and the newly promoted Sergeant Major Avery Johnson.<ref name="TheHeretic">''Halo 2'', campaign level [[The Heretic]]</ref> The ceremony was interrupted by the arrival of the Covenant [[Fleet of Sacred Consecration]], initiating the [[Battle of Earth]]. Upon discovering a Covenant [[antimatter charge]] on board ''Cairo Station'', John fought his way through waves of boarding parties until he reached the bomb, allowing Cortana to access and deactivate it. Feeling he could put the device to better use than the Covenant, John launched himself and the charge towards the Covenant assault carrier ''[[Day of Jubilation]]''. A timely bombing run by Longsword interceptors opened a breach in the warship's hull, allowing John to direct the bomb into the ship's fusion core. With seconds to spare, he launched himself back into space just before the vessel detonated. The {{UNSCShip|In Amber Clad}} quickly recovered the free-falling Spartan.{{Ref/Reuse|h2 cairo}}

John was then deployed to [[New Mombasa]], [[East African Protectorate]] aboard the ''In Amber Clad'', in an attempt to board the ''[[Solemn Penance]]'', the [[Prophet of Regret]]'s flagship. Both of the strike teams' [[D77-TC Pelican|Pelican]] dropships were shot down by a [[Type-47A Scarab]]. John and the surviving Marines fought their way to the other Pelican's crash site. After rendezvousing with [[Gunnery Sergeant]] [[Stacker]] at [[Hotel Zanzibar]] in [[Old Mombasa]], the Master Chief destroyed Covenant infantry and armor along the shore of the city as he chased the Scarab.<ref>''Halo 2'', campaign level [[Outskirts]]</ref> Upon arriving at the edge of Old Mombasa, John commandeered a [[M808B Main Battle Tank|Scorpion tank]] from Sergeant Major Johnson, which he used to punch a hole through the city's alien occupiers.

[[File:H2A - Prophet of Regret hologram.jpg|thumb|250px|right|The Master Chief hunting the Prophet of Regret.]]

John and the Marines [[Raid on Kilimanjaro|traveled through the jungle]], searching for evacuation to a nearby military base. Johnson and his team split up from John and the Arbiter. The sergeant and his squad were captured by loyalist Covenant Brutes, although they were soon rescued by John and 'Vadam. After taking heavy fire from [[Type-52 Troop Carrier|Phantoms]], a Pelican dropship evacuated the team to a UNSC base known as [[Crow's Nest (location)|Crow's Nest]].<ref>''Halo 3'', campaign level [[Sierra 117]]</ref>

In [[2557|July 2557]], nearly five years after John went into cryo-sleep, the aft half of the ''Forward Unto Dawn'' entered orbit above [[Requiem]], a Forerunner [[shield world]]. As [[Jul 'Mdama's Covenant|Covenant]] forces near Requiem began to board the ''Dawn'', Cortana awakened John from cryosleep. With Cortana's assistance, John fought off the intruders across the ship and used one of the ship's [[M4093 Hyperion nuclear delivery system|nuclear missiles]] to destroy an incoming [[CRS-class light cruiser|Covenant cruiser]]. Shortly afterward, however, Requiem's access gateway opened, pulling the remains of the ''Dawn'', as well as any Covenant ships in immediate proximity, into the interior of the shield world.{{Ref/Reuse|H4D}} Having crashed on Requiem, John took notice of Cortana's escalating signs of rampancy and she explained that her condition may be reversible if they managed to get to Earth and find Dr. Halsey in time.<ref name="H4R">''Halo 4'', campaign level [[Requiem (level)|Requiem]]</ref> Fighting their way through numerous Covenant forces occupying the structure, John was attacked by advanced Forerunner combat constructs which Cortana identified as [[Promethean]]s. Evading or destroying pursuit, John attempted to warn the approaching {{UNSCShip|Infinity}} of the dangerous gravity field that had disabled the ''Forward Unto Dawn''.<ref name="forel">''Halo 4'', campaign level [[Forerunner (level)|Forerunner]]</ref>

[[File:H4 John-117 Didact first encounter.jpg|thumb|left|250px|John is overpowered by the recently awakened [[Ur-Didact|Didact]].]]

Regrouping aboard the ''Infinity'', Captain Del Rio dismissed the threat of the Prometheans and prepared the ship to depart the system. Defying direct orders, John took the increasingly unstable Cortana and departed the ''Infinity''. Armed with a [[D79-TC Pelican#Gunship variant|Pelican gunship]] provided by Commander Lasky, John launched several attacks on support pillars providing the Didact's Cryptum with shields and power, with the goal of preventing him from leaving the planet and attacking Earth and other colonies.<ref name="H4S">''Halo 4'', campaign level ''[[Shutdown]]''</ref> John's attempt to stop the Didact ultimately proved unsuccessful, as the Didact managed to leave Requiem aboard [[Mantle's Approach|his vessel]], escorted by a flotilla of Covenant ships. Stowing away aboard a [[Deployment Platform Type-56 Ground Support/Ultra Heavy|Lich]], Master Chief pursued the Forerunner to [[Ivanoff Station]], a UNSC research base orbiting Halo [[Installation 03]] where the Composer was kept. [[Sandra Tillson|Dr. Sandra Tillson]], a lead researcher aboard the base, helped guide John to the artifact amidst a swarm of Covenant attackers. Despite John reaching the artifact first, the Didact was successful in obtaining the Composer and immediately tested the device on the crew of the station, completely destroying their bodies and assimilating their minds to power additional war machines. However, John survived, thanks to the genetic enhancements imposed by the Librarian.<ref name="composer">''Halo 4'', campaign level ''[[Composer (level)|Composer]]''</ref>

[[File:John and Cortana re-unite - Close shot.png|thumb|right|300px|Cortana paid the ultimate price to ensure the Didact's defeat and John's rescue.]]

With the Didact approaching Earth, planning to imprison all of humanity into digital form, John pursued the Forerunner aboard an [[F-41 Broadsword|Broadsword]] fighter on the outer hull of the Promethean's ship. As the ship exited slipspace near Earth, John was surprised to find the ''Infinity'' and the rest of the [[UNSC Home Fleet|Home Fleet]] ready and waiting for the Didact. John was able to destroy the ship's point defense guns, giving ''Infinity'' the chance to punch through the vessel's hull. Entering the breach, John fought his way to the Forerunner's location.<ref name="midnight">''Halo 4'', campaign level [[Midnight]]</ref> Despite the UNSC's best efforts, the Didact was to fire on Earth with the Composer, digitizing the entire population of [[New Phoenix|New Phoenix, Arizona]]. Armed with a [[HAVOK tactical nuclear weapon|HAVOK warhead]], John confronted the Didact for the second time on a [[hard light]] bridge. While John was no match for the Forerunner's powerful abilities, the dying Cortana was able to immobilize the Didact with hard light shackles. The weakened John then planted a [[pulse grenade]] in the Didact's armor, blowing him off the bridge and sending him falling into a slipspace rupture underneath the Composer. With time having already run out, John detonated the nuclear bomb manually as a desperate last resort.{{Ref/Reuse|midnight}}

{{Main|Skirmish on Installation 03}}

On [[2557#July|July 25, 2557]] John was debriefed by the [[UNSC Security Council]], though this questioning session as well as his survival were kept secret from Doctor Halsey.<ref>''Spartan Ops'', [[S1/Invasion|S1E7 ''Invasion'']]</ref> John confirmed that Cortana and the Composer were both destroyed over Earth, but he was unable to confirm the Didact's death. With there being no proof of a living [[Forerunner]], the Council decided to tell the general public that the attack on New Phoenix was caused by the [[Covenant remnants]] and ended by the return of a hero, the Master Chief. Following his meeting with the Security Council, the Master Chief met with [[Terrence Hood|Lord Terrence Hood]]. Hood asked the Master Chief if he could advise a team on Installation 03 to investigate the loss of contact with a science team escorted by Spartan [[Black Team]] on the ring. The Master Chief then reunited with [[Blue Team]], consisting of [[Frederic-104]], [[Kelly-087]], and [[Linda-058]].

John and the rest of Blue Team took a Longsword fighter to Gamma Halo and landed in near the science team's camp. There, the Spartans found the corpses of both the science team and Spartan Black. After being attacked by Promethean Knights, Blue Team discovered the former location of the Composer and within, the [[Composer's Abyss]], a facility used to store the Composer's victims.<ref name="HE8">''Halo: Escalation'', [[Halo: Escalation Issue 8|Issue #8]]</ref> The Spartans entered a [[slipspace portal]] at the end of the Abyss and were [[Slipspace translocation|teleported]] to the [[Composer's Forge]], housing six new Composers, where they were confronted by the Didact and his Promethean constructs. During the battle, [[859 Static Carillon]], the Forge's [[monitor]], transported Installation 03 over the Forge by the Didact's request. The Didact subsequently took one of the Composers and departed for the Halo, intending to use the ring to eradicate humanity. Infuriated by the Didact bringing his "abominations" to the Composer's Forge, Static Carillon allied with the Spartans and escorted them back to the portal, holding off the hordes of Promethean machines.<ref name="HE9">''Halo: Escalation'', [[Halo: Escalation Issue 9|Issue #9]]</ref>

Blue Team returned to the surface of Gamma Halo from the Composer's Abyss, arriving just in time as the Didact's new Composer rose from the pit. John fell behind while the Didact attacked and prepared to kill the others, starting with Kelly. Before he could do so, the Master Chief snuck up behind the Didact and stabbed him in the eye with his combat knife. Intending to correct his mistake of not having killed the Spartan when he had the chance, the Didact grabbed John by the helmet, lifted him up in the air and squeezed, cracking his visor.{{Ref/Reuse|HE9}} However, the rest of Blue Team intervened, forcing the Didact to throw John aside. The Forerunner quickly and easily subdued all four Spartans, but Static Carillon arrived and teleported the Didact into the Halo's [[Control Room (Installation 03)|control room]] before he could finish them off.<ref name="HE10">''Halo: Escalation'', [[Halo: Escalation Issue 10|Issue #10]]</ref>

After recovering, John picked up the ring's [[Activation Index]] the Didact had dropped and intended to confront the Forerunner in the control room while the rest of the team returned to their Longsword. Using the Index to override the system's safeties, the Master Chief gave control of the Halo to Static Carillon who then ejected the section of the ring housing the control room, causing it to plunge toward the planet below. The monitor teleported John away just as the segment struck the Composer's Forge and the Didact was disintegrated by the Composers. John and Static Carillon materialized aboard Blue Team's Longsword, where the monitor bade farewell to the Reclaimer before departing to take Gamma Halo to an undisclosed location.{{Ref/Reuse|HE10}}

Before the two Spartan teams could team up, Cortana separated Blue Team from Osiris in separate parts of the installation.<ref name="h5 genesis">''[[Halo 5: Guardians]]'', campaign level [[Genesis (level)|Genesis]]</ref> Blue Team fought an uphill battle through Promethean forces and multiple bodies of the Warden Eternal before physically meeting Cortana. There she revealed to them her plan to use the Guardians as a means of enforcing a forced peace upon the galaxy, giving sentient beings "a chance to be more than they are naturally". Comparing Cortana's behavior to that of Doctor Halsey's SPARTAN-II program, John pointed out a flaw in Cortana's plan: high collateral damage and a loss of free will. John pleaded with Cortana to stand down and return to Earth with the team. Cortana refused and forcibly sealed Blue Team in a Cryptum, intending to keep them in stasis for 10,000 years.<ref name="H5GTB">''Halo 5: Guardians'', campaign level [[The Breaking]]</ref> With the aid of [[031 Exuberant Witness]], Fireteam Osiris narrowly managed to free Blue Team from the Cryptum. Upon his release, John asked Locke where Cortana was; Locke could only respond, "''Gone, sir.''"{{Ref/Reuse|H5GG}}  

Upon their arrival at Sanghelios, now mostly in the dark due to the Guardian attack at Sunaion, they correctly deduced they’d find their allies near the region of [[Nuusra]].{{Ref/Reuse|BB}} There they regrouped with [[Thel 'Vadam]] and his [[Swords of Sanghelios]] who had just [[Battle of Sunaion|destroyed]] the remaining cell of [[Jul 'Mdama's Covenant]]. In 'Vadam's [[Sangheili hut|field command post]], John and Locke also met up with Spartan Commander [[Sarah Palmer]] and Dr. [[Catherine Halsey]], whom John had not seen since before [[Operation: FIRST STRIKE]] in 2552.<ref name="H5GG">''Halo 5: Guardians'', campaign level [[Guardians]]</ref> Spartans then were invited to join Sangheili in a celebratory meal commemorating their victory, while the Arbiter and the Master Chief subsequently spent part of the night reminiscing about their past. Also the Arbiter reassured the Chief in his support in the coming fight against the Created. The next day, the humans left the planet for a rendezvous with the {{UNSCShip|Infinity}} near [[Suban]], one of the moons of Sanghelios.<ref name="BB">'''[[Halo: Bad Blood]]''', ''Chapter 1''</ref>

On October 7, [[2559#October|2559]] John and the rest of Blue Team, now outfitted with new sets of [[MJOLNIR Powered Assault Armor (GEN3)|third-generation Mjolnir armor]], were deployed from ''Infinity'' on Reach in an [[Owl]], the {{UNSCShip|Special Delivery}}. The team's mission concerned the penetration of the rubble-filled ruins of [[CASTLE Base]] and the recovery of top-secret assets locked away in Doctor Halsey's abandoned laboratory there. It was hoped that the assets in question could prove useful against Cortana.{{Ref/Novel|Id=Chapter 1|HSoR|Chapter=1}} Trying to escape the enemy pursuit, who discovered their insertion craft, the Owl's pilots, Major [[Eznik Van Houte]] and First Lieutenant [[Maks Chapov]], attemted a vanishing maneuver resulting in their emergency crash-landing on glassed surface of Reach. To repel the enemy attack on their crash site, whom John identified as the [[Banished]], Spartans used the [[Wikipedia:Drilling jumbo|drilling jumbo]] as an anti-aircraft turret against [[Morsam-pattern Seraph|Seraph]] patrol. Collecting the Owl's crew and mining machines, Blue Team proceeded in the direction of [[Highland Mountains]].{{Ref/Novel|Id=Chapter 2|HSoR|Chapter=2}} To speed up the mission John suggested to commandeer a [[Banished Phantom|Phantom]] from Banished controlled [[Kisköre Base]]. Splitting his team in two, John ordered Linda to protect the Owl's crew and mining machines while he, Kelly and Fred infiltrated the base. However, as the fighting started, his squad came under heavy attack by [[Banished Banshee|Banshee]] squadrons guarding the base. John was hit in left leg, Kelly took a serious shot to the chest and Fred suffered a severe concussion. In order to escape the enemy fire, Kelly blew a hole in the glassed surface of [[Kisköre Canal]] and the team ended up inside an old half melted water pipe going under the canal. There John, Kelly and Fred encountered members of [[Viery Militia]] led by Colonel [[Sasa Boldisar]].{{Ref/Novel|Id=Chapter 5|HSoR|Chapter=5}} The militiamans led Spartans to their [[Logistics Base Gödöllő|base]] where John learned that there were actually three different clans amongst the Banished: [[Legion of the Corpse-Moon]], [[Ravaged Tusks]] and [[Keepers of the One Freedom]] working together to find something and that the militia were planning to use [[HAVOK tactical nuclear weapon|HAVOK]]s recovered from an old UNSC armory to draw the Banished away from Reach. Realizing that nuclear explosion would inevitably draw attention of Cortana and chances of success of Operation: WOLFE would be reduced to zero, John suggested helping the militia to take down Banished armory in [[New Mohács]], calling in additional Spartan support from ''Infinity''.{{Ref/Novel|Id=Chapter 10|HSoR|Chapter=10}}

====Battle of Installation 07====

{{Main|Installation 07 conflict}}

[[File:HINF-MynameisAtriox.png|thumb|300px|John defeated at hands of Atriox.]]

As they were planning their next move to stop the Banished from using the Halo, The Weapon intercepted a UNSC distress signal and traced it to another Banished [[The Tower|outpost]]. Esparza delivered the Master Chief to a closest save position from there Chief proceeded to investigate a distress signal. On his way, he recaptured [[FOB Golf]], one of the UNSC [[Forward Operating Base]]s occupied by the Banished.{{Ref/Quest|Id=recovery|HI|Lockdown (Halo Infinite)|Recovery}}  Reaching the Tower John successfully infiltrated the base and on top level discovered a Spartan [[Hudson Griffin]] trapped in a large machine and tortured by [[Chak 'Lok]], Sangheili Warlord in charge of the facility. The two dueled one-on-one and John killed Chak 'Lok. Despite being freed from a torture device, Griffin succumbed to his wounds, but not before informing Chief of the Banished's search for the [[Conservatory (location)|Conservatory]] at the [[Site Novem|Excavation Site]] up north of the Tower.{{Ref/Quest|Id=tower|HI|Lockdown|The Tower}} Acting on Griffin's information, John and the Weapon investigated the coordinates. At the seemingly deserted dig site, they found that the [[Brute laser drill]] had cut through Forerunner materials into a subterranean structure. However before they could enter, the drill activated and cut off their entrance. As John got to the drill's control room, he was confronted by the dig site security commander Chieftain [[Bassus]]. After a brutal fight, the Master Chief managed to kill Bassus, allowing the Weapon to overload the mining drill and destroy it granting them a safe passage inside the structure.{{Ref/Level|Id=Excavation Site|HI|[[Excavation Site]]}}  

Once inside the Coservatory John fought through Banished troops until he encountered the [[117649 Despondent Pyre]], the monitor of Installation 07. Suddenly the Pyre was attacked by [[Skimmer]]s and rushed away.{{Ref/Quest|Id=conservatory|HI|Connections|Conservatory}} Following the monitor deeper into the structure, Chief soon discovered it's dismantled chassis. As the Skimmers returned attacking the Chief, the Spartan fought his way out of the Conservatory. However near the exit he was met by [[The Harbinger]], a member of ancient [[Xalanyn]] race imprisoned by the Forerunners on Zeta Halo and awakened by the Banished. Using the [[encephalon]] she retrived from the Pyre she initiated the process of [[Reformation]] and then fled the facility heading towards the nearest [[Reformation Spire]] with Master Chief on tail.{{Ref/Reuse|conservatory}} After dealing with the Banished guards outside, John and the Weapon entered the Spire and encountered the [[Adjutant Resolution]], the Installation's [[sub-monitor]], who informed them of the Spire's purpose: to rebuild the Ring. As the Master Chief could not allow that to happen, he ordered the Weapon to shut down the Spire, which made the Resolution intervene by inserted himself into a [[Sentinel mech]] and attacking Chief in attempt to defend the Spire. Victorious, John and the Weapon initiated shutdown and escaped the collapsing tower onboard ''Echo 216''. Onboard the Weapon revealed a whole network of structures like this across the Ring controlled from the Command Spire suggesting it as their next objective.{{Ref/Quest|Id=spire|HI|Connections|Spire (Halo Infinite level)|Spire}}

[[File:HINF ChiefVsTovarus.png|thumb|300px|John and Tovarus engaged in combat.]]

However, while en route to the Command Spire, ''Echo 216'' was hit by [[Gorespike cannon]]s and crash landed.{{Ref/Quest|Id=pd|HI|Graveyards|Pelican Down (Halo Infinite level)}} The Master Chief proceeded to destroy each cannon with the help of the Weapon, while Esparza stayed behind in crashed Pelican. Eliminating the Banished defenses and clearing a path futher, John returned to crash site, but was confronted by [[Tovarus]] and [[Hyperius]], two Jiralhanae brothers and members of [[Hand of Atriox]], a special operations unit trained by Escharum for single purpose - to track down and kill Spartans. After a long fight the Master Chief managed to defeat the Spartan Killers and retrieved the Esparza. Reunited they proceeded to the Command Spire.{{Ref/Reuse|pd}} Anticipating the Chief's intent to stop the Reformation, The Harbinger modified the data sequence for accessing the [[Nexus (location)|Nexus]] locking down it's entrance. Upon this discovery the Weapon developed a plan to bypass the lockdown by utilizing data strands gathered from nearby Forerunner energy [[Beam emitter|beacons]]. As the task was completed the pair entered the Nexus.{{Ref/Quest|Id=sequence|HI|Reformation|The Sequence}}  

Exiting the portal John and the Weapon found themselves inside a Forerunner structure known as the [[Repository (location)|Repository]]. There the AI uncovered a message left behind by Escharum where he taunted the Spartan with a recording of Esparza being tortured and where he embedded his coordinates so as to make it easier for John to find him.{{Ref/Quest|Id=repository|HINF|Reckoning|[[Repository (Halo Infinite level)|Repository]]}} Proceeding through the Repository, the Master Chief and the Weapon discovered many fragments and memories of Cortana, shining the light on the events that led to creation of the Weapon in the first place. Observing Cortana's cruel actions during the [[Created conflict]], the Weapon was horrified and became even more devastated when she realised that she was an actual copy of Cortana. Afraid of becoming as merciless as Cortana was she restored her deletion protocols and asked Chief to complete his original mission. John refused, insisting that they could do it together, though while he didn't trust her, he'd wanted to.{{Ref/Reuse|repository}}

Emerging on the surface, the Weapon identified the Escharum's coordinates as the [[House of Reckoning (location)|House of Reckoning]]. Nearby, the Master Chief discovered a small Banished outpost where he killed the forces guarding it and commandeered a [[M808 Scorpion]] tank parked there. Utilising the heavy firepower John cut through Banished garrison and reached his target.{{Ref/Quest|Id=road|HI|Reckoning|The Road (level)|The Road}} Once inside, Escharum made Chief fight through multiple waves of Banished troops in several arenas constructed from UNSC ordnance and buildings up until he was confronted by Jega 'Rdomnai.{{Ref/Level|Id=House of Reckoning|Hi|[[House of Reckoning]]}} Despite using his [[active camouflage]] extensively, 'Rdomnai was ultimately killed by the Master Chief, finally avenging the several UNSC personnel that he had ambushed during the six-month-long Banished occupation. As John arrived at the heart of the House of Reckoning, he found Esparza locked at a similar torture device as Spartan Griffin was. As he attempted to free the pilot, the Spartan was attacked by Escharum. With the AI assistance John managed to outsmart and defeat the Brute War Chief and free Esparza. Mortally wounded but not dead yet, Escharum staggered over and demanded that the Spartan continue their battle. However, the Master Chief refused and caught and held the dying Escharum who promised that his death would inspire a thousand others and requested that the Spartan tell them that he had died well. Escharum then died of his wounds in the Master Chief's arms, surprising Esparza with the respect that the Spartan had given to the War Chief as he died given the latter's reputation as a monster. The Master Chief recognized that in the end, Escharum was just a soldier, hoping he'd done the right thing and questioning his choices. While Esparza believed that it was over with the death of the Banished's leader, the Master Chief warned him that it was not that simple and that there would be consequences as there always were. Recognising that imminent threat in tha face of the Harbinger remained, the trio recovered ''Echo 216'' and Esparza flew John to the Silent Auditorium.{{Ref/Reuse|House of Reckoning}}

Despite the Banished set up defenses to protect the Harbinger, John managed to breach inside. As they were fighting through enemy ranks the Weapon revealed to John that the Silent Auditorium was the place were Cortana was locked down and where she died. Deeper inside the structure they encountered more echos of Cortana reminiscing her actions and repenting, realising her mistake in assuming the [[Mantle of Responsibility]] for herself, which ultimately led to humanity's downfall, John's supposed death and allowed Atriox and the Banished to get control over Zeta Halo and free the [[Endless]]. And as she could not allow that to happen, she destroyed part of the ring, keeping the Banished from being able to use it, which also prevented the Weapon from being deleted, knowing that the Master Chief if he is alive would need the other AI's help. After witnessing Cortana's sacrifice, the John and the Weapon were stunned by her actions.{{Ref/Level|Id=Silent Auditorium|Hi|[[Silent Auditorium]]}} Later on the pair were once again met by Adjutant Resolution, though this time the submonitor provided assistance and unlocked a safe passage for them. He expressed his apologies for his earlier hostility outbursts as he belived the Harbinger was trying to repair the Ring, but in truth she only needed a mean to free her people, which could not be allowed. When the Master Chief reached the main chamber, he discovered that the Harbinger was interfacing with transmitters to locate the members of her species. The Weapon attempted to intercept the connection by disabling transmitters. With the help of an unknown entity, the Weapon managed to shut down all three transmitters, but not before the connection successfully located the Endless. At the same time, the Master Chief fought and eventually defeated the Harbinger and her Banished and Skimmer allies. Dying, she sent a message to an unseen ally of her own, telling them that they had what they needed and vowed to the Master Chief that the Endless would return.{{Ref/Reuse|Silent Auditorium}} As the Harbinger died John and the Weapon were met with yet another echo of Cortana, though this one was a direct message to John. In it she expressed hope that her plan worked well and John had found his way this far with assistance of his new AI partner and called this a chance to make amends and to rectify mistakes. Cortana admited that she was wrong, having forgotten that the reason that she chose the Master Chief in the first place was because they were supposed to be the perfect team together. And that in her final moments she wanted to make sure that John and his new companion learned from her mistakes and became stronger because of them. As the message ended the last remaining echo of Cortana faded away leaving John devasted and the Weapon speachless. And at the same moment the Auditorium started to collapse around them cutting off the exit. But sudden appearance of a portal allowed the pair to escape the crumbling structure.{{Ref/Reuse|Silent Auditorium}}

The portal led them to somewhere in desert land on the opposite side of Halo ring. The Weapon informed John that somehow it took them three days to reach this location. Soon they were extracted by Esparza, who received the signal from Chief's beacon. With the intention of finishing the fight the team traveled back to Outpost Tremonius from where they could proceed with liberation of Halo from Banished occupants.{{Ref/Reuse|Silent Auditorium}}

John is also noted for his exceptional luck, which, along with his combat skills and unyielding persistence, has allowed him to emerge victorious from situations many would consider impossible. Because of his many years of constant combat and military conditioning, John is not as emotional or sensitive as he once was, especially to fear. Although he is not devoid of fear, he simply acknowledges the feeling and puts it aside.<ref name="HTFOR22">''Halo: The Fall of Reach'', Chapter 22</ref> He is calm in the face of danger but not foolhardy, as demonstrated during his first encounter with the Gravemind, when he warned the Arbiter that his arrogance was likely to get him killed.{{Ref/Reuse|H2G}} John is generally stoic and taciturn, but not devoid of a sense of humor and often makes dry remarks about the situation in hand to his teammates and allies.

He does not see himself as a superior being and fears for the lives of others before his own, putting himself in harm's way for the safety of civilians, and fellow soldiers, and does not judge others. Indeed, he is known to show an exceptional care for soldiers under his command and has shown great respect for the baseline humans he has fought alongside. An example of this is during the Battle of Installation 04. When making his way up to the [[Silent Cartographer]], two Helljumpers, PFC [[Hosky]] and [[Unnamed Corporal|another Corporal]], were killed by two Hunters. Afterward he regretted their loss, blaming himself for their deaths.<ref name="HTF6">''[[Halo: The Flood]]'', Chapter 6</ref> This, and his reaction to [[Avery Johnson|Johnson]]'s death on [[Installation 08]] show that he does exhibit care and sympathy for soldiers under his command, even if he does do a good job of concealing his feelings. In the first two days of training on Reach, John learned two lessons that affected him personally and which he took to heart: you win if the team wins, and the team is stronger together than any one individual alone. He never endangers the lives of those under his command if it is unnecessary. He would rather risk his own life instead of the others. During the [[Battle of Circinius IV]], he drew a Hunter's attention in order to give the cadets a chance to run away, even with him running out of ammo. Deciding to follow Cortana's lead to [[Meridian]] on his own, John wanted to keep other Spartans from violating the UNSC regulations, though they decided otherwise and chose to remain by his side. He was also impressed by the humans who comprised his team following his escape from Installation 04, including [[Sheila Polaski]] and [[Locklear|Corporal Locklear]], both of whom he considered to have been worthy of being Spartans.<ref name="HFS36">''Halo: First Strike'', Chapter 36</ref><ref name="HFS26">''Halo: First Strike'', Chapter 26</ref>

[[File:H4-E3-Campaign-9.jpg|thumb|250px|John participating in the Requiem Campaign alongside Spartan-IVs and regular marines.]]

Throughout his training, John proved himself as one of the most promising leaders among Spartans, and Dr. Halsey considered him the best candidate in the entire program. His aspiration to win and his care of his teammates eventually helped him gain the position of squad leader. In years to come, many Spartan fireteams emerged with their own leaders. John took command of Blue Team, though he kept his commander role for the whole SPARTAN-II company. During [[Operation: SILENT STORM]], John so greatly impressed [[Colonel]] [[Marmon Crowther]] that the Colonel, who had previously expressed doubts about the Spartans, promoted John to the rank of Master Chief Petty Officer from the rank of Petty Officer First Class, a previously unheard of three-rank bump. However, Crowther recognized that John's inexperience left John having trouble differentiating between being a commander and a leader and gave the young Spartan advice that he would take to heart.<ref name="HSS23">''[[Halo: Silent Storm]]'', Chapter 23</ref>

As a senior Spartan, John took his responsibilities very seriously. After the augmentation procedures that took lives of nearly a half of Spartans, John was devastated; observing how his crippled brothers and sisters were transferred to other UNSC divisions almost made him furious.<ref name="HTFORTAS">''[[Halo: The Fall of Reach - The Animated Series]]''</ref> He did not want to lose them, though he understood that they could no longer fight alongside him. John was the one who volunteered to test Mjolnir armor even after Dr. Halsey confirmed that all previous testers died in process. Being a leader, John would not order his men to do what he could not do in the first place. He was always confident in his men's capabilities, suggesting the most proficient ways to solve the matter, which were considered by non-Spartan personnel as suicide.

What affected John the most were the deaths of people under his command; John considered every Spartan lost during the war as his own mistake, swearing to become stronger the next time.{{Ref/Reuse|HLTP}} During the Fall of Reach, John lost contact with his Spartans, however, he was sure that some of them survived the glassing and was determined to save as many as he could. More than once John took command of mixed units or squads consisting of Marines. He was capable to organize them to act as a Spartan fireteam, achieving despite almost impossible odds. On Requiem, during the initial engagements between UNSC and Promethean forces, John assumed tactical command of ''Infinity''<nowiki>'</nowiki>s ground forces including Spartan-IVs, despite being outranked by many of them.{{Ref/Reuse|infil}} Upon his return to Blue Team, Fred-104 ceded command to John despite outranking him. Blue Team also willingly followed John when he chose to go AWOL.

After the end of Human-Covenant War, John became an icon as a soldier who had played a pivotal role in ending the decades-long war and in doing seemingly gave his life.  He was lauded as representing the ideal of a human soldier by UNSC [[propaganda]], a view embraced by many among the general population. Considering John his personal hero, journalist [[Benjamin Giraud]] attempted to find out about his background and personal history.{{Ref/Reuse|HTTS11}} When John was declared dead, on many human worlds statues were built in his honor.<ref name="TC">''[[The Cost]]''</ref> Private companies started selling [[Toy|action figures]] in John's likeness; [[Gabriel Thorne]]'s grandmother bought one after he was recruited into the [[SPARTAN-IV program]].<ref name="HE7">''[[Halo: Escalation]]'', ''[[Halo: Escalation Issue 7|Issue #7]]''</ref> During his military career John served as a source of inspiration and morale booster for others whenever he was on a battlefield. Chief's determination and selflessness made [[Thomas Lasky]], then a young, doubtful cadet, dedicate his life to military service, eventually reaching the position of commanding officer of [[UNSC Infinity|the most advanced human ship]]. In the case of [[Connor McGinnis]], who was attempting to desert the UNSC after witnessing the horrors of the Flood, John was able to inspire him to not only rejoin the fight willingly, but insist on being sent on further missions. With the development of [[SPARTAN-IV program]] many soldiers enlisted with Spartans to be like the legendary "Master Chief". Such as [[Gabriel Thorne]], who enlisted believing the Spartans were special, and that had he been one, he could have saved his family in [[New Phoenix]]. Years later, when the UNSC discovered that the Chief actually survived and managed to prevent the Didact from enslaving the entire human race, they decided to cover it up as a Covenant remnant attack which was successfully fended off via perfectly timed return of the UNSC's greatest hero, thus again underlining the Spartan's supposed invulnerability.{{Ref/Reuse|HE8}} However, when Chief decided to go AWOL the UNSC declared him KIA during Battle of Meridian in order to hide his status and preserve his reputation.<ref name="AHF">''[[A Hero Falls]]''</ref>

In [[2590]], there was a ceremony for John-117 at an unspecified location near the areas of fighting during the Battle for Earth. However, his coffin is empty.<ref name="gravesite">[https://youtu.be/pOLR4WjJqIs ''Believe'': Gravesite]</ref> In [[2607]], the [[John-117 Monument]] began construction to commemorate the Spartan's service to mankind.

As a Spartan-II trainee, one of the first suits of armor John was introduced to was a type of form-fitting, lightweight polymer [[black body suit]].{{Ref/Reuse|HTFOR9}} This suit could deflect small-caliber rounds and was equipped with a refrigeration and heating unit that could mask infrared signatures. The integrated helmet had encryption and communications gear, a [[heads-up display]], and thermal and motion detectors.{{Ref/Reuse|HTFOR9}} John could also activate headlamps on the helmet and attach a [[fiber optic probe]] to it.<ref name="HTFOR10">''Halo: The Fall of Reach'', Chapter 10</ref> Sealed tight, the entire unit had a fifteen-minute reserve of [[oxygen]] to let John survive in vacuum.{{Ref/Reuse|HTFOR9}} Though still a little bulky if trying to hide it beneath clothing, the armor's tightness made it uncomfortable and limited his range of motion.{{Ref/Reuse|HTFOR9}}{{Ref/Reuse|HTFOR10}} Additionally, it also often needed repairs but was difficult to repair in the field.{{Ref/Reuse|HTFOR9}} John used one of these suits during training and also during [[Operation: TALON]], the first real mission given to the [[Spartan]]s.{{Ref/Reuse|HTFOR9}}{{Ref/Reuse|HTFOR10}} During the op, he was shot in the side at three points by an [[HMG-38]] rifle.

Immediately after the [[Mission to Installation 03]], John received an upgrade for his Mark VI armor from [[ONI]]'s [[Watershed Division]], bringing it into the GEN2 line of Mjolnir PAA.<ref name="Easterling2">[https://twitter.com/GrimBrotherOne/status/782402924353757184 ''Jeff Easterling on Twitter:] ''"GEN2; in Escalation."''</ref><ref name="Easterling">[https://twitter.com/GrimBrotherOne/status/791063783280025601 ''Jeff Easterling on Twitter'':] ''"Chief does have specific design from MG, but Blue Team as a whole all have WD influence :-)"''</ref> The armor still looks like his updated GEN1 Mark VI, the most prominent difference being a redesigned bodysuit.
