## Biography

### Becoming a Spartan

John was taken from his home by the age of 6 by UNSC Agents to become the ultimate soldier. He was given the number 117. After 8 years of cruel training on the planet Reach, John 117 was one of the few survivors of spartan body augmentations and was assigned for the Spartans of blue team, Kelly, Linda, Fred and Sam, as their leader. After the augmentations he was promoted to Master Chief. In his first mission against the covenant he and Blue Team infiltrated a Covenant ship. They succeeded but they lost Sam.

### Installation 04

After the devastating Fall of Reach, one of the few ships that escaped the glassed planet, the Pillar of Autumn crashed at a colossal, mysterious ring. The Master Chief escaped the ship with an escape pod. He landed on the ring and learned that the ring world is called Halo and can destroy all life in 25,000 light years, a fact that his AI friend Cortana told him. He also learned of a parasite called the Flood that was on the ring and it infected the Pillar of Autumn's captain, Jacob Keyes. the Master Chief went to the crash site of the Pillar of Autumn and destroyed its reactor, which led to the destruction of the ship, the Halo and a covenant armada. Although, the Installation's monitor, 343 guilty spark survived.

### The battle of Earth

"Sir, permission to leave the station?"

"For what purpose, Master Chief?"

"To give the covenant back their bomb."

-Chief and Lord Hood

Sometime later in 2552, the Master Chief, Sergeant Johnson and the daughter of Jacob Keyes, Miranda Keyes, participated at the battle of Cairo Station (after Lord Terrrance Hood gave them medals for their bravery) when the Covenant attacked earth. The aliens put a bomb in the space station but chief (and Cortana's chip in his helmet) stopped it from exploding and deactivated it in the last second. After being permissioned to leave the station, the Master Chief flew in space to a covenant carrier and reactivated the bomb near the carrier's reactor.

### Battle of New Mombasa

"The Chief is gonna jump in this tank, roll across the bridge, and blow up any inhuman son of a b\*tch dumb enough to get between him and the prophet of regret! Pull yourself together, 'cause you're comin' with him!"

Sargeant Major Johnson to Master Chief and two marines

After the ship got destroyed, he landed on an UNSC frigate known as the In Amber Clad and flew to the city New Mombasa in Africa. When he landed he helped some marines destroy a giant Scarab and returned to the In Amber Clad. The In Amber Clad was chasing the Prophet of Regret's flagship, which was escaping earth through a Slipspace portal. The frigate reached the ship in the last second, created a giant Slipspace rupture and destroying a large part of the city.

### Installation 05

The frigate's crew discovered another Halo, called Installation 05. during the raid on the installation, The master chief killed the prophet of Regret and Sergeant Johnson and Miranda fought the covenant's new Arbiter, Thel Vadam but were interrupted by the Brute chieftain Tartarus, who told the Arbiter that the prophets betrayed the elites, captured Miranda and pushed him to the abyss. Meanwhile, Master Chief escaped a glassing beam from a covenant ship and fell to the water but was kidnapped by the flood Gravemind (The Flood leader) which also kidnapped the Arbiter. Together, they escaped the Gravemind. The Arbiter and Johnson rescued Commander Miranda Keyes, stopped Tartarus from activating the Halo ring and killed him. Meanwhile, Chief and Cortana chased the Prophets of Mercy and Truth on their flagship High Charity. While the Prophet of Mercy was killed by the flood, Truth escaped the High Charity. Chief was forced to leave Cortana in High Charity and to return to in Truth's forerunner dreadnought earth to finish the fight.

### Return to earth

Chief flew from space to earth and survived, thanks to his armor and augmentations, which made his bones nearly unbreakable, and reunited with Johnson and the Arbiter. The Master Chief and the marines traveled through the jungle, searching for a base nearby. when they came they learned that the Prophet of Truth is going to destroy the base and evacuated all of the troopers.

### Battle of Voi and the portal to the Ark

The UNSC flew to the city of Voi, where they discovered a portal to Installation 00, the Ark, which could activate all of the Halo arrays and destroy all life in the galaxy, but the covenant was already their, believing The Ark's activation will lead them to paradise. John and Installation 04's monitor, 343 guilty spark went to rescue Cortana from a Flood Infested covenant light cruiser, but all they found was a message of her. To prevent the Flood's escape, the Arbiter's ally Rtas 'Vadum glassed the entire city, much to Lord Hood's displeasure. Cortana's message says that the Gravemind is coming to Earth with an army of Flood, and that on the other side of the portal is a solution to the Flood infestation, without having to fire the rings.

### The Ark

The UNSC fleet went to the Ark to prevent the Prophet of Truth from activating the remaining 6 Halo rings. The Prophet of Truth kidnapped Johnson and his Brute guards tortured him in the Ark's citadel and Miranda Keyes went to rescue him with a pelican, but was killed by Truth. Then, the Prophet of Truth forced Johnson to fire the halo rings. Chief and the Arbiter entered the citadel and allied with the flood's Gravemind to stop Truth. The Master Chief deactivated all of the halo rings while the Arbiter avenged Truth and killed him with his Energy Sword. Johnson escaped with Keyes' crashed pelican while Chief and the Arbiter fought the Gravemind who has betrayed them. They escaped the flood and John went to save Cortana aboard the flood infected High Charity, who crashed on the ring. He eventually found Cortana and both escaped and killed the Gravemind, but soon learned that a replacement of Installation 04, Installation 08 was constructed and the Gravemind went there in order to rebuild himself.

### Finishing the fight

Johnson, Master Chief and the Arbiter went to fire the halo near the Ark, which will destroy the Ark and the flood without wiping out all life in the galaxy. 343 Guilty Spark was there, ready to fire the Halo but betrayed the team when the monitor learned that they're gonna fire it near the ark and killed Sergeant Johnson. Chief took Johnson's Spartan Laser and destroyed 343 guilty spark with it. Chief fired the Halo and he, the Arbiter and Cortana escaped in time to the UNSC Forward unto Dawn. The Forward unto Dawn was spilt to 2 halfs: one contaited the Arbiter, who returned to earth and went to the war victims' funeral, Including Johnson, Keyes and John, who was presumed dead.

### Lost in space

"Wake me, when you need me."

Master Chief to Cortana

The second half which contained John and Cortana was lost in space. Because of that, Cortana sent a distress beacon to the UNSC, and Chief entered Cryo Sleep. The ship was eventually drifting to the Forerunner Shield World of Requiem.

### Requiem

"The Forerunners have returned."

-Ur Didact

After nearly 5 years in space, the Forward unto Dawn crash landed at Requiem. Cortana woke Chief up and explained him that she's rampant, means she will start to act different than she normally does, and eventually become crazy. They picked up a signal which they thought to be an ally. John reached a ball shaped object and tried to contact the Infinity, the flagship of the UNSC but accidently awakened the Ur Didact, a forerunner who was imprisoned on the planet about 100,000 years before for actions against humanity. Chief tried to defeat him but was easily defeated. John escaped to the jungles of Requiem where the Infinity crashed while searching for the Chief due to the gravity well inside the planet. There he found Captain Andrew Del Rio, captain of the Infinity, Commander Thomas Lasky, who John-117 rescued once as a cadet during the war against the covenant and Commander Sarah Palmer, the Commander of all of the fireteams at the Infinity and helped them defeat the attacking covenant remnants which joined the Didact's Prometheans, an army of mechanical soldiers who were once living forerunners under the Didact's command in the Forerunners' war against the humans, and cannot be corrupted or infected by the Flood. After that he and some UNSC forces destroyed the gravity well and freed the Infinity. During the fight, John had a vision of the Libararian, the Didact's wife, who told him that the Didact is looking for the Composer, a Forerunner device that is capable of bridging organic life and digital technology together, creating Prometheans, and to use it on Earth. She also gave him an immunity to the Composer.

### Disobeying Orders

Del Rio: "I. Am ordering you. TO SURRENDER THAT AI!!!"

John: "No, sir."

Del Rio: "Lieutenant, arrest that man!"

Lasky: "Captain-"

Del Rio: "ARREST HIM!!"

After he learned about the composer John-117 returned to the Infinity and told Del Rio about the information he discovered but the Captain refused to pursue the Didact. Cortana then screamed on the Captain that she doesn't allow the Infinity to leave the planet as a part of her rampancy. Then Del Rio ordered Lasky to give him Cortana's chip for deletion but John took it first and went to pursue the Didact alone, despite Del Rio threatened to arrest him.

### Pursuing the Didact

"Before this is all over, figure out which one of us is the machine."

-Cortana, to Master Chief before the chase

After Lasky secretly wished them good luck, Chief and Cortana went to stop the Didact from leaving Requiem but failed. Chief boarded a Covenant starship and followed the Didact's ship, the Mantle's Approach, into spilspace. The Mantle's Approach arrived at Ivanoff Station where the Composer was, in an asteroid field near Installation 03. Despite his efforts, Dr. Tilson, the Head scientist of the station refused to remove to Composer from the station. The Didact took the Composer to the Mantle's Approach and killed everybody, including Dr. Tilson, except fot John. The Master Chief flew in a broadsword, with a nuclear bomb from the station to earth, where the Didact activated the composer on earth inside the Mantle's Approach. Surprisingly, Captain Lasky assisted him with the Infinity, revealing that FLEETCOM didn't like Del Rio's actions and demoted him. Eventually, Chief's Broadsword crashed on the Mantle's Approach and Chief took the bomb with him, fighting waves after waves of Prometheans while Cortana splitting fragments of herself. When he reached the Composer and the Didact, the Forerunner has bested him and when he was about to kill him, Cortana's fragments distracted him so Chief could defeat him. Chief planted a Promethean grenade in the Didact's chest and before the latter could kill him, it exploded and caused the Didact to fall into a Slipspace rupture below. Then the Chief took a last look on Earth and activated the nuclear bomb, destroying the Mantle's Approach. However, Cortana teleported him away from the blast in her last powers.

### Aftermath

"Our duty, as soldiers, is to protect humanity... whatever the cost."

"You say that like soldiers and humanity are two different things. Soldiers aren't machines. We're just people."

"She said that to me once. about being he machine..."

-Master Chief and captain Lasky

When chief woke up, he was in a strange area. He called Cortana's name. John received no reply, and began to look around to see a human sized Cortana standing before him. She said that she will not come with him this time, resting her hand on his armor for the first time. The Chief reminded Cortana that it was his job to protect her, however, she told him that it was their job to look after each other—and that they had done so. Then she began to walk away and disappeared. John then woke up in space surrounded by the debris of the Mantle's approach. After he was found by a Pelican dropship, he was brought to the Infinity to speak with Lasky. While both took a look at Earth, Lasky sympathized with him and said that he lost many people he cares about. Master Chief said that the duty of soldiers is to protect humanity, whatever the cost. Lasky replied that soldiers aren't machines, but people. John remembered Cortana's wish to figure out which one of them is the machine. Lasky left the Infinity's bridge, letting John to have the deck for himself.

### The next 72 hours

After a long time, John reunited with Blue team the day after the Didact's defeat. They were sent to investigate what happened to another SPARTAN II fireteam, Team Black, on Installation 03. They eventually discovered that Team Black were killed by the Didact, who managed to survive his fall to the Slipspace rupture and was teleported to the Installation. Blue Team found the Composer's abyss which leads to the Composer's Forge, where there were 6 other Composers and the Didact, with his Prometeans. The Didact asks 859 Static Carillon, the monitor of the Installation if he can move it above the planet, which he does, and the Didact takes a Composer to the Installation, planning to use the ring and Composer to wipe out humanity. However, Carillon feels betrayed by the Didact because he brought his Prometheans to the Installation and decides to help Blue Team. Blue Team fought the Didact but he overpowered them. Suddenly, John stabbed the Didact in the eye but the Forerunner choked him and made a hole in the Spartan's visor. before the Didact could finish John Carillon shot the Didact with his beam and teleported them to Halo's control room. The Didact asked Chief if he would kill all life in the Galaxy just to finish him, but John had other plans. The part of the ring where the Didact and John stood on crashed on the Composer's Forge, and Static Carillon teleported the Spartan into Blue Team's Ship, while the Didact was composed. However, when John returned to the UNSC he stated the the Didact wasn't dead but contained. After the mission Chief spoke with lord Hood, which told him to remove his armor and take a vacation. However, Chief met with Blue Team and together they went to missions across the galaxy.

### Going AWOL

In one of their missions, Chief had a vision of Cortana calling him to the planet Genesis. He asked permission from the Infinity to do that but was declined, being informed that another Fireteam will do that but he went with Blue team anyway. Blue team went to the planet Genesis after a short fight with the other Fireteam's Leader, Jameson Locke. The vision was actually a trap that Cortana, who was alive through the Domain, has set to imprison Blue Team for 100,00 years while taking control of the galaxy. The plan failed with Blue team being released by the other fireteam, Osiris but Cortana escaped them with a massive forerunner weapon called a Guardian. Cortana went to disable the Infinity on Earth but it escaped on the last second. All of the other ships on earth were disabled. She also destroyed the UNSC HQ in Sydney, Australia and with 7 Guardians, destroyed the Brute homeworld of Doisac and its moons.
