"They let me pick. Did I ever tell you that? Choose whichever Spartan I wanted. You know me. I did my research. Watched as you became the soldier we needed you to be. Like the others, you were strong and swift and brave. A natural leader. But you had something they didn't. Something no one saw, but me. Can you guess...? Luck."

— Cortana

Master Chief Petty Officer of the Navy John-117 is a SPARTAN-II commando of the UNSC Naval Special Warfare Command. He served as one of the most important figures of the Human-Covenant War. With nearly thirty years of active duty, he is one of the most decorated war veterans in the UNSC Defense Force, having served in more than 200 ground engagements against the Covenant and earned every major service medal except the Prisoner of War Medallion. In late 2552, John-117 went missing in action after the Battle of Installation 00, when he and the current Arbiter, Thel 'Vadam, fired Installation 04B.

Among most humans, John-117 is simply known as the "Master Chief," the "Chief," and "SPARTAN-117." The Covenant is aware of the power of the SPARTANs, and refer to John as "the Demon." John is referred to as "Reclaimer" by both 343 Guilty Spark and 2401 Penitent Tangent, although this is a universal title given to all humans, rather than specifically John.

Biography

Childhood and SPARTAN training

John-117 as a young child, with Halsey deciding his fate with a 21st century quarter.

Born in about 2511, John lived with his mother and father in Elysium City, on the colony world of Eridanus II. He attended the Elysium City Primary Education Facility Number 119. As a child, John had brown hair, freckles, and a small gap between his front teeth. In a memory, John recalled that his mother was kind and smelled of soap. The would-be UNSC Marine Lieutenant Parisa was a childhood friend of John's. John once saved her from drowning at Lake Gusev, after which John promised to marry her and keep her safe. A photo of the two was also taken by Parisa's father soon after, and would be kept as a memory by Parisa long after she thought John had passed away.

"You like games? So do I."

— Dr. Catherine upon meeting John for the first time.

At the age of six, he was identified by Dr. Catherine Halsey as one of 150 preliminary candidates for the SPARTAN-II Program. John was an ideal physical and mental candidate, standing a head taller than the majority of his schoolmates, having greater physical proportions, possessing greater strength, exhibiting superior reflexes, and having an aggressive drive for success. By the time he was conscripted, he had a string of forty-five victories in what Dr. Halsey referred to as a "brutal version" of King of the Hill, resulting in him having a chipped tooth and his opponents suffering various bone fractures.

When Dr. Halsey and Lieutenant Jacob Keyes visited Eridanus II in 2517 to study him, they were impressed with his intellect and luck. In a final test of his viability as a candidate, he was asked to determine which side an old coin would land on. He watched the coin as it flew in the air and caught it before it could land; correctly stating which side was face-up, on the side of the eagle. Later that same year, John and 74 other six-year-old children were "conscripted" to Reach: they were covertly kidnapped from their homes and replaced with flash clones, all of which would later die of natural causes to cover up the kidnappings. Dr. Halsey informed them of the SPARTAN-II Program and how they would be the protectors of Earth and all its colonies. The next morning John discovered his service tag, stitched into his training uniform, and his new name: John-117.

John began a new life, training with other Spartans under Chief Petty Officer Franklin Mendez. For eight years he learned history, military strategy, weapons, and was given physical fitness training. Early on, he bonded with Kelly and Sam, who would be the only close friends he would ever have.

During his training, John quickly proved himself to be considered one of the program's top candidates. Both Dr. Halsey and Chief Mendez identified him as one of four emerging leaders within the SPARTAN-II group, along with Kurt-051, Jerome-092, and Frederic-104. Dr. Halsey expressed her belief the most strongly in John as having the skills and natural ability to lead the entire Spartan-II group, although Mendez disagreed, instead believing Kurt would fulfill that role.

When the Spartans were eight years old, they were sent on a training mission in which they were dropped over a forest located deep in one of Reach's Highland Mountains and expected to get safely to their extraction - an Albatross dropship. The children also had instructions to leave the last trainee arriving behind, or the punishment would be painful, but John-117 knew that he could not do that. After telling the Spartans where to meet, the Spartans looked to him as their leader, a role he was initially surprised to be given, but eventually accepted. When the group came across the Albatross, it was guarded by armed men. Those men were actually UNSC Marines, but were not in uniform, thus leading the Spartans to mistake for a hostile threat. John showed early acumen in critical thinking and tactics, not wishing to take for granted that guards would be friendly toward them. He came up with a plan to take the men down, capture the dropship, and ensure the safe extraction of every team member, as he made sure he was the last person aboard. To do this he ended up hijacking the dropship with the help of Déjà, and beat down the men with stones, causing severe injuries among the Marines. Chief Mendez was not visibly pleased, as John had attacked his Marines and no one had been left behind. However, both Mendez and Halsey recognized John's initiative, and promoted him to Squad Leader. After this, despite the other Spartans rising in rank and at least a couple rising to lead their own teams, he remained the de facto leader of the Spartans as a whole.

John's leadership skills were correctly observed, as the result from their mission clearly solidified his role as the overall leader of the Spartan-IIs. He also became the established leader of the Spartan-II's Blue Team.

At the age of 14, John underwent the dangerous SPARTAN-II augmentation procedures. These procedures caused 30 of the Spartan trainees to die, and 12 to become physically disabled. John was one of 33 Spartans who made it through the process unscathed, while the rest who could still operate were sent for jobs in the Office of Naval Intelligence. At only 14 years old, it is said that John had a body of an 18-year old Olympic athlete; the augmentation process gave the Spartans faster reflexes, greater strength, enhanced eyesight, and made their bones nearly unbreakable. Following their augmentation procedures, John and the other Spartans were transferred to the Atlas in order to recover in a microgravity environment. During his first visit to the Atlas' gym, John was confronted by four ODSTs, whose sergeant then ordered the five of them into the boxing ring. In the ensuing fight, John inadvertently killed two of the ODSTs, and left the others severely injured. According to Major Antonio Silva, this incident was orchestrated by the Office of Naval Intelligence in order to test the Spartans' augmentations.

Early military career

John-117's first mission was against rebels in the asteroid belt of the Eridanus System, where his home world was located. He was shot in the side by live ammunition while leading his squad to capture rebel leader Colonel Robert Watts, without heavily injuring him. The mission casualty list is 11 dead rebel soldiers and unknown rebel civilians. He received a Purple Heart after this mission for taking a round in the side.

Three months after the Eridanus mission, John and his Spartans were briefed on the massacre that took place on Harvest shortly after first contact with the Covenant. A short time later, the UNSC Commonwealth, under the command of Captain Wallace, brought the Spartans and Dr. Halsey to the Damascus Testing Facility at Chi Ceti, where they received the MJOLNIR Mark IV Powered Assault Armor. When a Covenant ship, the Unrelenting, attacked the Commonwealth, John and the SPARTAN-IIs took part in their first engagement with the Covenant. The Spartans used thrusters to launch from a Pelican dropship. Each Spartan carried an ANVIL-II Air-to-Surface Missile to destroy the Covenant ship. Only two other Spartans made it to the ship with John: Samuel-034 and Kelly-087. They entered the ship through a hole in its hull, caused by a MAC round from the Commonwealth. They succeeded in completing the mission and destroyed the Covenant ship, but due to a breach in Sam's armor, caused by retaliation fire from Covenant forces, he was unable to leave the Covenant ship. Volunteering to stay behind and ensure the destruction of the enemy vessel, Sam was killed in the ensuing explosion. John was affected profoundly at the loss of one of his friends. This UNSC victory against the Covenant showed John that the Covenant weren't invincible and could be beaten, but at a very high cost. John and the remaining Spartans would fight the Covenant for the next 27 years, employing their MJOLNIR armor.

In 2544, John, along with Fred-104, Kelly-087, Solomon-069 and Arthur-079, was part of a mission to rescue Dr. Catherine Halsey from a Covenant fleet. The team utilized OF92/EVA "Booster Frame" fighters, which were designed for ship boarding actions, and infiltrated the assault carrier Resplendent Fervor. Aboard the assault carrier, John encountered Sangheili Major Thel 'Lodamee, who challenged John to an energy sword duel. Thel was forced out of the duel when his Fleet Master separated the lower section of the assault carrier to kill the Spartan, pulling him back into the upper section. Both combatants were left unscathed. The Spartans completed the mission and rescued Dr. Halsey, but Arthur and Solomon were killed. John was saddened by his teammates' deaths and vowed to be stronger and never let such a loss happen again.

John served in over 200 missions against the Covenant, including the Harvest Campaign, the Battle of Jericho VII, where he and a handful of Spartans single-handedly killed over a thousand Grunts, and the Battle of Sigma Octanus IV, in which John and his Blue Team detonated a HAVOK nuclear warhead to clear Covenant forces from the city of Côte d'Azur. This was one of only a few UNSC victories against the Covenant. By summer of 2552, he had received every medal awarded by the UNSC except the Prisoner of War Medallion (since the Covenant did not take prisoners and John would not allow himself or any SPARTAN to be captured by the enemy.)

Fall of Reach

Main article: Fall of Reach

On August 29, 2552, during the Covenant's invasion of Reach, which had been waged for over a month, John received an upgrade to his Mark V MJOLNIR armor as well as an upgrade to his neural interface, allowing him to support an artificial intelligence. He was then introduced to and partnered with the AI Cortana, who would become a close friend and ally to him. In the first test of their partnership, the two were put through a practically suicidal test in an attempt by Colonel Ackerson to get rid of John. John refused to cheat the test and was determined to win it by Ackerson's rules. Despite nearly being killed, Cortana and John's teamwork had them pass the test in an early show of the incredible partnership the two would come to develop.

On the following day, the majority of the SPARTANs were deployed to protect the generators which powered the planet's twenty Orbital Defense Platforms. John, with Linda and James, was sent to Gamma Station to destroy an unsecured navigation database onboard the prowler Template:UNSCship. If the Covenant obtained the database, they would discover the location of every human world, including Earth. The NAV database was destroyed, but Linda and James were ambushed by Covenant Sangheili; James was lost in space and Linda was critically wounded. John saved four Marines on the station, including Staff Sergeant Avery Johnson. The team returned to the Template:UNSCship and was placed into cryo-sleep as the ship landed on and later fled Reach, and, following the Cole Protocol, jumped into slipspace with coordinates deduced by Cortana from constellation data retrieved earlier, in hopes of leading the Covenant away from Earth.

Installation 04

"Get Cortana off this ship. Keep her safe from the enemy. If they capture her, they'll learn everything. Force deployment, weapons research... Earth."

— Captain Keyes

"I understand."

— John-117

Once the ship had arrived at Installation 04, it emerged that the Halcyon-class cruiser UNSC Pillar of Autumn had been followed through Slipspace by around a dozen Covenant ships, who ultimately engaged the Autumn and sent several boarding parties to board the ship. Captain Jacob Keyes ordered John to be woken from cryosleep, and tasked him with ensuring the escape of, Cortana (who was acting as the ship's AI), while he crash-landed the Pillar of Autumn on the unidentified ring.

Initially, fighting on Halo was between UNSC and Covenant forces, but after Captain Keyes unwittingly released an ancient parasite, the majority of both forces were infected, and the fighting shifted to combating the new enemy.

John-117 was sent out by the Installation's monitor, 343 Guilty Spark, to retrieve the Index, an activation device for the Halo ring that the Master Chief is led to believe would destroy all Flood forms within a large radius. Upon John's return to Halo's Control Room, Cortana revealed that Halo's true purpose is to destroy all sentient life forms in the galaxy to starve the Flood, not to kill the Flood themselves. John was then forced to disrupt Halo's firing system by disabling Halo's phase pulse generators in order to delay the Monitor's plan.

John soon joined the three-sided combat among the Covenant, the Flood and the Forerunners' Sentinels. Soon after, he tried to rescue Captain Keyes, but was too late. Captain Keyes had been transformed into a Proto-Gravemind Flood form. After infiltrating the Truth and Reconciliation, the Chief managed to retrieve the Captain's neural implants, which he used to activate the Pillar of Autumn's self-destruct sequence. After the sequence was aborted by 343 Guilty Spark, he proceeds to manually overload the fusion reactors, which would subsequently destroy both the Pillar of Autumn and Installation 04.

After successfully destroying the fusion reactors on the Pillar of Autumn, John-117 used a Warthog to reach the extraction point where Pelican Echo 419 would pick him up. John-117 reached the extraction point, only to witness the Pelican crashing into the Autumn's hull after being shot down by a pair of Banshees. The Chief quickly diverts his escape route towards the ship's hangar bay, which housed a Longsword fighter. Only a handful of UNSC forces survived, including Lieutenant Elias Haverson, Corporal Locklear, Warrant Officer Sheila Polaski and then-Staff Sergeant Avery Johnson.

FIRST STRIKE

Main article: Operation: FIRST STRIKE

After the destruction of Alpha Halo, Cortana and the Master Chief fled through space in the Longsword they had escaped in. He discovered three cryotubes floating nearby, one containing Linda-058, and retrieved them. Soon after, the Covenant flagship Ascendant Justice and several cruisers appeared from behind Threshold, having taken cover from Halo's destruction. A nearby Pelican dropship which had docked on an asteroid floating among Halo's debris field fired at the cruiser to distract it. After a successful escape from the Covenant battle group, John linked the two vessels and brought its passengers aboard the Longsword. The crew of the Pelican then helped John in capturing the Ascendant Justice; the human survivors then traveled to Reach to look for surviving Spartans.

John eventually located some of his fellow SPARTAN-IIs on Reach, along with Vice Admiral Danforth Whitcomb and Dr. Catherine Halsey. They returned to the ship and linked it with the UNSC frigate Gettysburg. Before traveling to Earth, they decided to head into the Eridanus system where they discovered that the rebel base Eridanus Secundus was still intact, now led by 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 an enormous fleet was poised to invade Earth.

John faced a dilemma regarding the combat data on the Flood which Dr. Halsey had given him. Providing the standard data set to Lieutenant Haverson would protect Sergeant Johnson from possible experimentation by ONI. However, providing him the complete data, which contained reference to Sergeant Johnson's escape from the Flood due to his Boren's Syndrome, would result in Johnson's death.

John and the few remaining SPARTAN-IIs, Linda-058, Grace-093, William-043, and Fred-104, focused on finding a way to stop the Covenant from reaching Earth, the location of which had been discovered. They decided to destroy the Unyielding Hierophant. The SPARTAN-IIs infiltrated the station; after spending eleven hours on board, they arrived at a temple, where a copy of Cortana warned them of the Jiralhanae guards stationed at the temple. Linda took a sniping position and the other four Spartans entered the temple. They were ambushed by Brutes, and John was nearly killed, but the team managed to kill their attackers. Grace, however, was killed by three Brute Shot rounds. John activated the fail-safe on her armor, denying her compromise by the Covenant.

The team sabotaged the generators in the Unyielding Hierophant; as they escaped through a side door, the fail-safe on Grace's armor activated, disintegrating a Covenant lance. John, Fred, and Will were quickly spotted by three Banshees, but their Elite pilots were killed by Linda's sniper fire. The Banshees were then captured by the Spartans. John doubled back to retrieve Linda, who killed four more Banshee pilots who were attempting to kill John. They then escaped by destroying a glass atrium, and arrived back at the Gettysburg.

Vice Admiral Whitcomb and Lieutenant Haverson piloted the Ascendant Justice straight toward the Unyielding Hierophant. Whitcomb discussed the battles of the Alamo and Thermopylae with John, then prepared to fight the Covenant off while the Unyielding Hierophant's fusion reactor detonated. Each of the 500 Covenant ships maneuvered next to the Ascendant Justice. The Admiral and the Lieutenant were killed when the fusion reactor exploded, annihilating 486 ships of the Covenant fleet, leaving only around a dozen intact; these ships later joined the Prophet of Truth's rebuilt fleet in the attack 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.

Battle of Earth

"What if you miss?"

— Cortana

"I won't."

— John-117

Aboard Cairo Station, John received the MJOLNIR Mark VI Powered Assault Armor and attended an awards ceremony with the newly-promoted Lieutenant Commander Miranda Keyes and Sergeant Major Johnson. The ceremony was interrupted by the arrival of the Covenant Fleet of Sacred Consecration, initiating the Battle of Earth. John successfully repelled Covenant boarders from the station. Upon discovering a Covenant antimatter charge on board Cairo Station, John fought his way through waves of Elites, Grunts, and Drones until he reached the bomb and allowed Cortana to access and deactivate it by transferring her back to his suit. Afterwards, she chose to rejoin him despite his offer for her to remain on the station. He used the charge against the Covenant by launching himself and the device, via decompression of one of the station's launch bays, towards a Covenant assault carrier. A timely strike by Longsword interceptors opened a breach in the warship's hull, allowing John to direct the bomb into the ship's fusion core. He then proceeded to use the blast from the bomb to launch himself back into the UNSC In Amber Clad.

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' Pelican dropships were shot down by a Scarab. John and the surviving Marines on his team 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 units along the shore of the city as he chased the Scarab. Upon arriving at the edge of Old Mombasa, John received a Scorpion Tank from Sergeant Major Johnson.

After fighting through numerous highway tunnels and suburbs, John reached the industrial zone, where Marines under the command of Staff Sergeant Banks were pinned down by Covenant forces. With the assistance of the Marines and a large stockpile of weapons, John boarded the Scarab and was able to destroy it and the Covenant forces protecting it. John was then transported to In Amber Clad to intercept the Prophet of Regret's flagship. When the flagship started to enter Slipspace, Lieutenant Commander Keyes was granted permission to follow it. John and all on board In Amber Clad were brought to Installation 05.

Installation 05

Main article: Battle of Installation 05

Forced to act quickly once at Installation 05, John deployed groundside in an SOEIV along with several Orbital Drop Shock Troopers. This team was tasked with locating and assassinating the Prophet of Regret. Cortana informed John of Regret's intent to fire Halo as soon as possible. He tracked the Prophet of Regret to a temple in the middle of a lake, but not before witnessing hundreds of Covenant vessels coming out of Slipspace, followed by High Charity. He assassinated the Prophet of Regret, and escaped the temple shortly before it was destroyed by an overhead cruiser. John jumped off the edge of the structure and into the lake below.

Losing consciousness and being unable to swim in the lake, he was captured by the Flood's central intelligence, the Gravemind. Shortly after, the Arbiter was also captured. The Gravemind appealed to the common interest that the Flood and the humans shared, that of not wishing the Halos to be fired. John agreed. The Gravemind then tasked both captives with locating the Index, sending them to the two most likely locations. John was sent to High Charity, interrupting a sermon by the Prophet of Truth. The conflict between the Sangheili and Jiralhanae was beginning, leading the Covenant on the path to civil war: John was caught right in the middle.

John chased the surviving Hierarchs through High Charity, eventually catching up to the Prophets and their Brute escorts. However, only a dying Prophet of Mercy, who had been compromised by a Flood Infection Form, was left to tell him that Truth was heading to Earth. John faced another crucial dilemma: the Covenant had the Index and could activate Halo; however, Earth's Home Fleet stood little chance of withstanding Truth's reassembled fleet. Ultimately, John followed the latter priority, forced to leave Cortana behind so that if Halo were activated, she would detonate In Amber Clad's reactors, not wanting to risk detonating them remotely. John boarded the Forerunner Dreadnought, which was bounding for Earth, but not before promising to return for Cortana after he stopped Truth.

Return to Earth

"Master Chief, you mind telling me what you're doing on that ship?"

— Lord Hood

"Sir, finishing this fight."

— John-117

After a series of firefights, captures and escapes, John exited the Dreadnought and crash-landed on Earth, where he was found by Sergeant Johnson, the Arbiter, and the rest of their squad. Johnson believed the Chief to be dead, and requested heavy lifting gear in order to recover the Spartan's body. However, John awoke to battle-ready condition only moments later, showing his incredible tolerance to pain and shock. He attempted to attack the Arbiter, believing that the Elites were still the enemy. Johnson informed him that the two races were now allies, as the disillusioned Arbiter and the Sangheili had defected from the Covenant.

John and the Marines 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 soon captured by Prophet-loyalist Covenant Brutes, although they were rescued by John and 'Vadam. After taking heavy fire from Phantoms, a Pelican dropship evacuated the team to a UNSC base known as Crow's Nest.

John-117 and the Arbiter prepare to fight through the jungle.

The base soon came under attack, but not before Fleet Admiral Terrence Hood told John his plan. Lieutenant Commander Keyes decided to evacuate all forces, many of whom were injured. John, Thel and the remaining UNSC Marines defended the base during its evacuation, planting a massive bomb to destroy the base along with the invading Covenant forces. The Master Chief fought his way through many Brutes, escaping the explosion in an elevator. He met up with several Marine survivors underground, and they escaped the base and headed for the city of Voi along Tsavo Highway, crushing Covenant resistance on their way.

At the Battle of Voi, John pushed through many Covenant forces as he made his way to what was believed to be the Ark. Rather, this turned out to be an artifact that opened a portal to the Ark. With Marine support, John and Thel 'Vadam destroyed three Anti-Air Wraiths, a Scarab, and a Covenant anti-aircraft battery, allowing Lord Hood's remaining frigates to fire upon Truth's Dreadnought, with little effect. Truth then activated and fled through the Portal with his remaining loyalist forces, while the UNSC remained behind to determine their next move.

Just as the battle seemed finished, a Flood-infested Covenant warship crash-landed in Voi. John, 'Vadam, and the remaining Marines fought to contain the Flood infection, learning that the only way to contain the Flood was to destroy the warship. During the battle, Shipmaster Rtas 'Vadum came to aid the UNSC. He deployed a Special Operations Sangheili strike team through orbital insertion pods, assisting John as he was sent to retrieve Cortana from the cruiser, as it was believed that she was on board. Aided by 343 Guilty Spark, John retrieved a damaged data device and was brought aboard 'Vadum's flagship, Shadow of Intent. This data turned out to be only a message, rather than Cortana herself. The Sangheili were able to stop the Flood infestation by glassing the city and its surroundings, much to Hood's displeasure.

The Sangheili and the UNSC watched Cortana's recording, which contained a warning that High Charity, now overwhelmed and controlled by the Gravemind, was heading for Earth. However, she offered hope, with information of a way to stop the Halos from firing and neutralize the Flood threat. Convinced of the reliability of Cortana's message, John resolved to journey to the Ark, while Hood mobilized remaining UNSC forces on Earth. John accompanied a joint UNSC-Sangheili task force through the portal aboard the UNSC Forward Unto Dawn to the Ark.

Installation 00

Main article: Battle of Installation 00

The Sangheili carried UNSC forces through the Slipspace portal which led to the Ark. The team was determined to stop Truth from activating the remaining six Halos. They descended in Pelicans while the Shipmaster's fleet fought hard against the Brute ships. They flew to the surface of the Ark to eliminate the Covenant loyalists in the area, to secure a landing zone for Forward Unto Dawn, and to find the Ark's Cartographer. Traveling in Scorpions, Warthogs, and captured Prowlers, John and other Marines located the Cartographer and learned that Truth was in the Installation's Citadel, a structure where the entire Halo Array could be activated. John then escaped from the Cartographer and proceeded to assault the fortress.

John-117, Thel 'Vadam, and a squad of Marines were assigned to separately attack three barrier towers, which were emitting a protective shield around the Citadel. Although John and 'Vadam managed to deactivate two towers, Sergeant Johnson was captured in the battle, being spared to activate the Halos from the Ark's Citadel. John, 'Vadam, and the Elites deactivated the last tower, lowering the shield. Just as the Shadow of Intent was about to destroy the Citadel, the Flood-controlled High Charity exited Slipspace, bringing the Flood into the battle and disabling the Shadow of Intent.

After defeating the last remnants of the Covenant forces around the Citadel, including two Scarabs, John and 'Vadam entered the Citadel. Although Miranda Keyes had forced her way in, breaking through the central window with her Pelican, she was soon surrounded. As she hesitated before killing Johnson and herself, Truth shot and killed Keyes with a Spiker. Truth then forced Johnson to begin the activation sequence. In an unexpected turn of events, John and 'Vadam made a temporary alliance with the Flood to stop the activation of the Halos. Truth's final defenses were crushed by the Flood as John and the Arbiter reached Truth, who was already being infected by the Flood. Then 'Vadam executed him with his energy sword, while John deactivated the rings.

The Gravemind then betrayed John and 'Vadam, laughing as it had succeeded in preventing its own destruction. After fighting past waves of Flood, the two escaped. As they were leaving the Citadel, John saw a vision of Cortana that led him to the exit. There, he learned her plan: a replacement for Installation 04 had been built by the Ark, and was not yet connected with the rest of the Array. Since the Halo was so far from the inhabited galaxy, John decided to activate the ring and destroy the Gravemind, but first headed to the remains of High Charity.

"You know me. When I make a promise..."

— John-117

"You...keep it. I do know how to pick 'em."

— Cortana

On High Charity, John battled his way through hordes of Flood, being taunted with images of Cortana falling into rampancy and by threats from the Gravemind. He finally reached Cortana, who still had the Activation Index from the first Installation 04. John then destroyed the city by overloading its backup generators. On his way out, Cortana detected a friendly contact, which turned out to be Thel 'Vadam. High Charity exploded as the trio narrowly escaped on a Pelican.

Activating the Halo

The Master Chief, caught unaware by 343 Guilty Spark's sudden attack on Sgt. Johnson.

The final task for John, 'Vadam, and Cortana was to destroy the Flood by activating the replacement Installation 04. The three landed on the Halo, finding that the Gravemind was trying to rebuild itself on the Installation. Flood dispersal pods released Combat Forms against John and the Arbiter, forcing them to fight their way up to the Control Room, where the ring could be activated. During the battle, Sergeant Johnson arrived and assist the Chief in battle.

After defeating all Flood forces around the Control Room, 343 Guilty Spark unlocked the door to the Control Room. Once inside, however, Guilty Spark realized that the team intended to fire the Halo before it could be completed, which would consequently destroy the ring. After mortally wounding Sergeant Johnson, he then turned on John.

"You are the child of my makers. Inheritor of all they left behind. You are Forerunner. But this ring...is mine."

— 343 Guilty Spark, betraying the Master Chief

John stood his ground, even after being hit by several energy blasts, and fought against Guilty Spark. Although the Monitor seemed to be invulnerable, Johnson shot the Monitor, temporarily distracting him. He then handed John his Spartan Laser, and John destroyed Guilty Spark. Johnson's injury was fatal, and he requested that John "send [him] out with a bang," after handing over Cortana's data chip and imploring him, "Don't ever let her go."

Cortana then activated the second Installation 04, and the survivors fled to the Forward Unto Dawn onboard a Warthog, fighting the Flood and local Sentinels on the way. The team boarded the Dawn and escaped the firing and destruction of the replacement Installation 04. However, the Slipspace portal opened for them could not sustain itself under the stress, and its closure severed the ship in half, sending 'Vadam to Earth. John and Cortana were left drifting in unknown space.

Missing in action

"But you did it. Truth, and the Covenant...the Flood. It's finished."

— Cortana to John-117

John and Cortana were presumed dead when they did not make it back to Earth. The forward half of the Forward Unto Dawn, bearing the Arbiter, crash-landed on Earth. Lord Hood commissioned a memorial near Mount Kilimanjaro in Africa in honor of UNSC servicemen lost during the war. As there were no pictures to remember him by, John's SPARTAN ID number, 117, was carved onto the memorial by an unknown party, and the UNSC Master Chief Petty Officer of the Navy insignia patch was taped beside his ID number.

"Were it so easy..."

— Thel 'Vadam, on the "death" of John-117

Ironically, he and a few other Spartans are the only ones truly Missing In Action.

Stranded in space

"Wake me...when you need me."

— John's last words to Cortana

John-117 and Cortana managed to survive the explosion of Installation 04B in the remaining cargo portion of the Forward Unto Dawn, but it was nearly powerless and, without airlocks or a bridge, could not be properly navigated. Cortana, relieved that John had survived, explained this to the Chief, and that it could take years before anyone could discover their distress signal. In a similar conversation to one at the end of Halo 1, Cortana listed what John did and told him "it's finished," and this time, John agreed with her. John placed himself in a cryotube, at which point Cortana said, "I'll miss you." John replied with "Wake me...when you need me."

In 2556, while still stranded in space, Cortana attempted to talk to John while he was still asleep. Unable to get a response from him, she recounted the history of the galaxy, seemingly unaware that John could not hear her, and showing major signs that she was descending into rampancy.

Five years after John went into cryo-sleep, the back half of the Forward Unto Dawn was caught into the gravity well of a mysterious Forerunner planet.

"Relax, I'd rather not piss this thing off."

— John-117

John's personality is explored much more deeply in the books than the games, so players can more easily project their own personalities onto the Master Chief.

As with all Spartans, John strives to win at any situation, at all costs. This was a part of his character even prior to his conscription to the Spartan program; as a child, he used to win at any game he played, including chess, gravball or King of the Hill. He is extremely determined to complete the mission at hand, and often disregards his personal safety and relies on his abilities and Cortana's intel. Indeed, he has often emerged victorious from situations many would consider impossible. Still, he is not devoid of fear, but he simply acknowledges the feeling and puts it aside, never showing it. However, there are a few exceptions, such as his first encounter with the Gravemind, when he warns the Arbiter that his arrogance is likely to get him killed.

John is generally stoic and taciturn, but not devoid of a sense of humor. He often makes dry remarks about the situation in hand; however, this seems to be more frequent when interacting with Cortana than anyone else, such as the other Spartans. 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.

John is known to show an exceptional care for soldiers under his command. An example of this is during the Battle of Installation 04. When searching for the survivors of the Pillar of Autumn's crash, Fitzgerald was wounded by an Unggoy Needler. John-117 retrieved a first aid kit and "expertly" treated the wound, before asking the Marine if he was okay. This, and his reaction to Johnson's death on Installation 04B shows that he does have a degree of care and sympathy for soldiers under his command, even if he does do a good job of concealing his feelings.

One thing that was noted is that John tends to keep his word when he gives it to someone. As he was forced to leave Cortana behind on High Charity, John promised to come back for her after dealing with the Prophet of Truth, but Cortana told him not to make a promise like that when he knew he could not keep it. However, John did keep his promise, pointing out that he always did to Cortana saying "You know me: when I make a promise..." causing Cortana to respond "You keep it," which seemed to give her strength as she gathered herself quickly when before she was somewhat depressed and hopeless while talking to him.

John greatly dislikes being kept in the dark. He dislikes secrets, and he dislikes ambushes, all in all, he doesn't dislike fighting, but knows when it is appropriate not to. One example is when he was cornered by three large ODST in a gym whilst working out. He did his best to try to call them off and avoid a fight, but in the end they kept pushing him to fight, and in the end, he was forced to defend himself. John knows when it is appropriate to fight, and when inappropriate, and has great control over his emotions and having a clear state of mind. Due to his augmentations, he thinks much faster than an average human, and sees things moving and happening much more slowly as a result. It is almost a clairvoyant state of mind, and as a result of this, has an acute intuitive insight and perception of any situation combat or non-combat.

Relationships

John holds a personal respect for his trainer and mentor SCPO Mendez, as well as Dr. Halsey, who he considers a mother-like figure.

John possesses a deep friendship with the AI Cortana who was assigned to him for his mission to capture the Covenant Prophets. Despite some initial hesitation towards working with an AI out of fear of conflicting directives, John and Cortana quickly formed a formidable team and John realized quickly that Cortana would be a great help instead of a liability. Their relationship evolved from a partnership to a close friendship over the course of the Halo: Combat Evolved, probably due in part to the amount of time the two spent with each other. During their adventures, John showed absolute trust in Cortana, believing in her when even Lord Hood was unsure of her reliability, even willing to trust her enough to risk Earth on her word that she had a way to stop the Flood. The two also had similar personalities in some areas: they both had a penchant for blowing things up with John commenting at one point he wasn't sure which one of them was better at it and also tended to come up with crazy plans. After Cortana told John his plan to use a Covenant bomb to blow up a Covenant carrier was crazy, he offered her to remain behind, but she simply responded with "Unfortunately for us both, I like crazy" and during the series, was shown to have some pretty "crazy" plans of her own.

John is known to be cautious and observative, only making changes in his plans if they are of the utmost necessity. He does not open easily to strangers. Friendships are made for life, however -- once given, his trust is forever, one example being Cortana, whom he once told to not get any funny ideas, upon being paired with his MJOLNIR Mk V armor, but in the end they formed a relationship that transcended the battlefield. Doctor Catherine Elizabeth Halsey, whom he considered a mother-like figure, the Spartans he grew up with as a child, such as Samuel-034, and Kelly-087, were very important to him. When feeling self-confident, he can be gentle, giving and protective of the needs of others. Because of many years of intense training and combat, and many years of loss and constant fighting he has grown numb to many emotions; he began to be less effected emotionally by defeat or the loss of a squad-mate. This isn't because he doesn't care, but because he has grown more accustomed to combat that most, even other Spartans, would consider 'emotionally challenging', and is known to be quite literal about the situation at hand.

Because of his many years of constant combat, he is not as emotional or sensitive as he once was, but still has an understanding of many emotions, such as fear, but he has learned how to overcome it in situations such as the Fall of Reach. John realizes his duty as a Spartan is to serve and help those in need, and unlike ODST can work expertly with anyone he is sent into battle with. The Spartans in his past, Cortana, and Dr Halsey, being the only family he really ever had, assume a larger-than-life importance for John-117. He has been known to have vivid and long-enduring memories of the past, such as in dreams, in particular the beginning of Halo: The Flood. No matter how well adjusted he is, however, John always seems to need to have a quiet place away from crowds after a battle in order to feel at peace.

Age

John's age is affected by the same ambiguities as all beings who undergo extended voyages through space. By technical human Earth years, John is approximately 41 years old at the time he crash-landed on Installation 04, and 45 years old in 2556. However, during the 27 Earth years that he has spent fighting the Covenant, and the five years that followed, considerable time was spent in cryo-sleep on long slipspace voyages. The aging process is slowed in slipspace by deep sleep in cryo chambers, in which cellular aging can be halted almost completely. As a result, John's biological age is significantly less than his age as measured by Earth-standard chronology.

Appearance

John-117's face has never been seen in the games, and therefore his appearance is left mostly to one's imagination. The novels Halo: The Fall of Reach and Halo: The Flood give some insight to John's appearance. Early in Halo: The Fall of Reach, when Dr. Catherine Halsey and Lieutenant Jacob Keyes go to Eridanus II to observe John as a child, he is described as "a typical six-year-old male, with tousled brown hair and a sly smile that revealed a gap between his front teeth". In Halo: The Flood, referring to John in 2552, he is described as having "Short hair, with serious eyes, a firm mouth, and a strong jaw." He is described as being unnaturally pale, a consequence of spending most of his time in his armor.

In the ending cutscene of Halo: Combat Evolved, John takes off his helmet, and the camera pans upward, leaving the head obscured by the ship window frame as he sets the helmet to his side. Some people have used Halo: Custom Edition development mode to move the camera. However, Bungie's 3D artists did not produce a separate character model for this occasion, just a separate helmet model; if the animation is viewed from inside the ship, it appears as if John takes off his helmet, revealing an identical helmet underneath. Players have also found an Easter Egg in the Halo 3 Beta. Using a Mongoose, players can reveal what looks like a face in a Spartan's helmet. However, Bungie has confirmed that this is Marcus R. Lehto's face, not John's.

For the first time, John's face was shown without a helmet in Halo: Helljumper Issue 1. The comic illustrated the fight between John and four ODSTs. As expected, his face is seen from the side and is covered up in shadow, hiding any specific facial features.

John's face is consistently shown throughout Halo: Fall of Reach - Boot Camp. However, John's facial features are not depicted as an adult.

Trivia

• John-117 is voiced by Steve Downes in the Halo trilogy, in Halo: Reach's Firefight mode, and in the audio version of Palace Hotel. In the Halo Legends shorts The Package and Odd One Out, John is voiced by David Wald.
• John is the protagonist and main playable character in Halo: Combat Evolved, Halo 2, and Halo 3. In the games, John is only referred to by name once, by Cortana, in the ending cutscene of Halo 3 before the credits.
• John-117's quote "No soldier should be honored for doing what is expected" is likely an allusion to Douglas MacArthur's similar quote "You are remembered for the rules you break, not follow." Another quote of his that is similar to MacArthur's is, "The best luck of all is the luck you make for yourself." which is similar to his quote in Halo: Legends, "We make our own luck..."
• Fans have many theories as to the significance of John's SPARTAN tag, 117. Inside the Halo universe the number was randomly assigned, but Bungie's choice has been theorized upon in many ways. For more, see List of references to religion in the Halo series. It was possibly chosen for its mathematical connections to seven, Bungie's favorite number, since 1*1*7=7 and 7^6=117649. John 1 Chapter 1, Verse 7, is a passage referring to God's who relinquishing of all evil from the world so people can believe, hence 'Believe' being part of the advertising campaign for Halo 3. In the year 117, "John I" became the 7th Bishop of Jerusalem. It is quite probable that John-117 is named in honor of John Spartan, the protagonist of the movie Demolition Man, who was kept in cryogenic storage as "Prisoner 117" for forty years. It could just also be a play on James Bond's number, 007. It may be a reference to First Wave, a television series about alien invasion whose main character was referred to as "Subject 117".
• A wax sculpture of the Master Chief can be visited at Madame Tussaud's, Los Angeles and in Amsterdam. He was the first video game character to become a Madame Tussaud's wax sculpture.
• Fable II makes a reference to the Master Chief with a character of legend named "Hal", also called the Minstrel Chief. The armor featured (clearly inspired by Halo's MJOLNIR Powered Assault Armor) is known as "Hal's Armor". The Energy Sword also makes an appearance as one of the first weapons you can attain with the Collector's Edition of Fable II. It is known as "Hal's Sword". The Assault Rifle can be acquired on the Knothole Island DLC as "Hal's Rifle", and has the largest magazine of any ranged weapon in the entire game, although its damage is low to average. In addition, with the Special Edition, the player can obtain the title "Master Chief" for their hero for free from any title vendor.
• John appears as an easter egg in Halo: Reach, asleep inside a cryo pod in the Pillar of Autumn's hangar.
• "John" is one of the name options for customized Loadouts in Halo: Reach, along with the members of Noble Team and several SPARTAN-II's.
• The Master Chief was voted the #4 game character of the decade in Game Informer Magazine, and the #1 character of the decade on Game Informer.com.
• Late in the development of Halo: Combat Evolved, (when the game was known simply as Halo), Microsoft urged Bungie to change the main character's title from "the Master Chief" to "the Commando", as they felt that it better suited the tone of the game.
