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... Was I wrong?

Summary

Master Chief (Real name John) is a UNSC Spartan soldier and the main protagonist of the Halo franchise. One of the only Spartan-IIs alive and the hero of the Human-Covenant War. Covertly kidnapped from his home as a child, he was raised from the age of six to be the ideal soldier: fearless, loyal, and resourceful with an unending drive for success. Enhanced with the latest in bio-augmentation technology available, he was one of the thirty-three Spartans to survive the procedures and was the first to utilize MJOLNIR body armor. His figure soon became synonymous with the SPARTAN Program and the UNSC, serving as a beacon of hope to his allies and a monster to be dreaded to his foes.

Stamina: Superhuman (Can last much longer on the battlefield than any of the UNSC marines and ODST soldiers, has the pain tolerance to continue fighting even when losing an arm. His stamina is further enhanced by MJOLNIR regeneration; in MJOLNIR he has proven himself capable of fighting with torn tendons in his limbs and even internal bleeding)

Range: Extended melee range; hundreds of meters with most ranged weapons, several kilometers with sniper rifles

Standard Equipment: Master Chief's Mjolnir armor lets him carry two small weapons or one moderate to large-sized weapon in the back, 2 small-sized weapons in his waist, and can carry small-sized weapons in his legs. (Although no Spartan to this date has ever done so). This is thanks to his magnetic weapon holder strips, and he actively uses one weapon or dual-wields two small ones. He can also carry various pairs of grenades (Up to a total of 4 pairs as seen in Halo 3) and even carry grenade triplets (As seen in Halo CE). Most if not all Spartans also carry a knife, mostly use for CQC combat or assassinations.

  • Standard Weaponry and Equipment:

  • MJOLNIR MK IV: John's first suit worn during the Fall of Reach. Titanium plating offers great protection against gunfire. This suit also allows John to link with his AI Cortana. It also multiplies his strength, speed, and stamina a few times over. No energy shields make the suit very susceptible to plasma.
  • MJOLNIR MK V: Suit John wears in Halo: Combat Evolved. Same features as his previous suit, except with an added energy shielding that offers him up to 15 megajoules of protection against plasma weaponry.
  • MJOLNIR MK VI: John's most iconic suit; grants twice the protection his previous suit does and further regenerative capabilities for the energy shields. Physical capabilities are also likely further enhanced.
  • MJOLNIR GEN 2: Armor Spartans wear in the new Halo trilogy. Does not feature many notable features, but it is lighter and further enhances physical skills than the GEN 1 MJOLNIR armors.

  • M6 Magnum: The UNSC's trademark pistol. Fires a 12.7x40mm M225 Semi-Armor-Piercing High-Explosive bullet at a muzzle velocity of 427 m/s. The kinetic energy of the 32 gram bullet would be 2917.3 joules. Street level Attack Potency and Supersonic Attack speed.
  • MA5 Assault Rifle: Rapid fires M118 7.62x51mm Full Metal Jacket Armor Piercing bullets at a muzzle velocity of 792 m/s. Kinetic energy of the 11 gram bullets would be 3450 joules. Street level AP and Supersonic AS.
  • M90 Shotgun: The UNSC's trademark Shotgun of the UNSC and the most recognized close up weapons used by humans. Fires a 3.5" soellkraft 8 Gauge Shell containing 15 9.5 mm diameter lead pellets at a muzzle velocity ranging from 300 to 400 m/s. Each of the pellets is 5.103 grams. Street level to Wall level AP and Subsonic+ to Supersonic AS.
  • SRS 99 Anti-Material: Sniper Rifle fires 14.5x114 mm Armor Piercing Fin Stabilized Discarding Sabot bullet at 1530 m/s. The kinetic energy of the 66.5 gram bullet would be 77834.925 joules. Wall level AP and Supersonic+ AS.
  • M41 SPNKr Rocket Launcher: The standard rocket launcher of the UNSC. It is designed to destroy Scorpion tanks, and KO multiple Spartans, and is the second strongest infantry weapon of the UNSC. Small Building level AP and Subsonic+ AS.
  • M6 Spartan Laser: Most powerful infantry weapons used by the UNSC and the strongest firearm John can carry; excluding Incineration Cannon. Can one shot KO multiple Spartans in a 2 meter blast radius. Building level+ AP and Speed of Light AS.

  • Drop Shield: Weaker version of the Bubble Shield; it has triple protection against projectiles as MJOLNIR energy shields do, but no protection against melee attacks.
  • Deployable Cover: Protects from all solid projectiles up to Building level level, but no protection against plasma and suffers from openings; allowing well placed small projectiles to go through.
  • Invincibility: Grants near invulnerability to various heavy weapons including Spartan lasers and Wraith Mortars. It also grants zero additional resistance against melee attacks or blunt force trauma.
  • Bubble Shield: Omni-directional field that shields off all projectiles and explosions, including multi megaton bombs, however, It is still passable by infantry troops and vehicles.
  • Hardlight Shield: A monodirectional shield that repels all infantry weapons, including the strongest Promethean weapons. Does not cover the backside or far well against melee attacks.

  • Additional Weaponry and Equipment:

  • Type-25 Plasma Pistol: Trademark plasma pistol of the Unggoy, Kig-Yar, and Yanme'e. Fires a small plasma bolt at a muzzle velocity of 108 m/s with an electric discharge of 20-45 Kilowatts, 300 - 450 Kilowatts when charged. Wall level AP and Subsonic AS.
  • Type-25 Plasma Rifle: Trademark plasma rifle of the Sangheili and Jiralhanae. Fires a plasma bolt at a muzzle velocity of 126 m/s with an electric discharge of 200 to 450 Kilowatts. Wall level AP and Subsonic AS.
  • Type-50 Sniper Rifle System: Covenant Particle beam rifle often used by Kig-Yar, and some Jiralhanae and Sangheili; Muzzle velocity is 3657 m/s. Wall level AP and Hypersonic+ AS.

  • Fuel Rod Cannon: Trademark weapon of the Mgalekgolo; fires Incendiary gel at around 1 Gigajoule of energy at 72 m/s. It can kill Spartans in 2 hits, with the second one melting through Titanium and vaporizing their flesh and blood. Small Building level+ AP and Subsonic AS.
  • Type-1 Energy Sword: The signature weapon of the Sangheili, and the most iconic melee weapon in Halo. It's composed of two plasma blades of electrical energy that can KO Mark V and below Spartans in one hit and drain all of MJOLNIR VI and above shields instantly leaving them with just a bit of life left. Is one of the few weapons John has yet to master but is still quite skilled with one. AP may be dependant on the wielder, but at least Small Building level+ when used by Spartans and Elites.
  • Type-2 Gravity Hammer: Signature Two-Handed weapon of the Jiralhanae. This 85-pound club is capable of flattening Spartans and other comparable troops in a single slam. Is also equipped with a gravitational field that triggers when the head of the hammer hits the ground; this does bonus damage and pulls enemies closer to the hammer. Natural AP is dependant on the wielder, but likely Building level when used by a Spartan or Brute, Higher AP with gravitational field.

  • Z-110 Boltshot: Traditional Handgun of the Forerunners, is typically carried by Crawlers and is used to disintegrate smaller enemies from close up. The muzzle velocity of the bolts is 73 m/s. Small Building level AP and Subsonic AS
  • Z-130 Suppressor: The Forerunners rapid-fire gun. Although the attacks are weaker than most Promethean weapons, it makes up for it by firing 900 rounds per minute each having a muzzle velocity of 98 m/s. At least Street level AP and Subsonic AS.
  • Z-180 Scattershot: Forerunner variation of the shotgun; comparable if not superior to the Binary Rifle. Fires 6 to 8 beams that when fired up close, ionizes Spartans. Has a surprisingly low Muzzle velocity and poor accuracy when fired from a distance. At least Building level+ AP and likely Subsonic AS.
  • Z-250 LightRifle: A well-rounded weapons used by the Prometheans. It's in many ways comparable to the UNSC Marksman Rifle but is likely stronger in canon. Likely Wall level AP with likely Supersonic AS
  • Z-390 Incineration Cannon: Most damaging infantry weapons in the series thus far, even surpassing the M6 Spartan laser; but suffers from poorer accuracy and speed. Muzzle velocity ranges from 48.4 m/s to 68.9 m/s Can greatly fragmentize various vehicles, including Wraiths and Scorpions, and disintegrates Mgalekgolo/Hunters. Was specifically created to kill Proto Gravemind Floods. Multi-City Block level AP and Subsonic AS.
  • Z-750 Binary Rifle: Sniper Rifle of the Forerunner, disintegrates Spartans and other comparable troops on contact; even completely overpowering their shields. Muzzle Velocity might be comparable to the Type-50 Covenant Sniper Rifles. Building level+ AP and likely Hypersonic+ AS.

  • Overshield: Doubles the strength of John's energy shields.
  • Active Camouflage: Grants John invisibility.
  • Speed Boost: Enhances the speed of movements, combats, and reactions for 45 seconds.
  • Damage Boost: Enhances the damage done with all weapons for 45 seconds.

  • Cortana: Cortana is John's most trusted ally and valuable weapon. Cortana is a extraordinary genius AI capable of performing futuristic calculations and computer skills. She can access/hack computers from a distance, gather information on John's opponents, clone herself, manage entire fleets, and plan excellent military strategies.
  • Thruster Pack: Grants John limited flight by hovering him in the air. Also increases his mobility and can perform the Spartan Ground Pound while in midair.
  • Genesong: A Gene the Librarian implanted into John's DNA to grant him the only way for him to go up against The Didact. It makes him immune to the Composer thus granting him resistance to Virtualization.

Intelligence: At least Gifted. As Doctor Catherine Halsey's favorite Spartan, John showed exceptional promise as a leader and soldier even at an early age. A natural leader, he rallied his fellow cadets to heavily injure and incapacitate a group of armed and trained UNSC Marines and steal their Pelican dropship at the age of eight. Since then, John has been trained in all forms of military warfare, being an expert in hand-to-hand combat, firearms usage, stealth tactics, and the operation of any number of military vehicles, being able to kill two elite ODSTs and maim three more when he was just fourteen years old. By the time of the Covenant-Human War, John was a decorated soldier who could turn the tides of battle almost single-handedly, leading UNSC forces to rout entire battalions of Covenant forces, being a key figure who was feared as "The Demon" by his opponents. Also, he gained extensive experience in the usage of Covenant and Promethean weaponry and machinery, oftentimes outdoing the original owners' in their ability to use said weaponry, managing to defeat the Didact's forces even though the Prometheans had spent thousands of years subjugating other civilizations.

Weaknesses: If he gets hit with enough force his armor might lock. Shields cannot regenerate while in the middle of rapid-fire attacks. MJOLNIR regenerating shields grant little protection against close-quarters combat attacks.

Notable Attacks and Techniques:

  • Spartan Charge: John slams into his enemy while sprinting at full speeds.
  • Spartan Ground Pound: While hovering with his thruster pack, John can perform a powerful ground pound attacking multiple targets within the attacking circle.
