Master Chief Petty Officer John-117, also known as Master Chief is the main protagonist of the Halo franchise. He is a Spartan-II super soldier of the UNSC Navy.

“	I do not remember my name. I do not remember my family. I do not remember my home. But I can remember the game. We played it every day. And I never lost. The game... It's the only thing I can remember about the life I had before I met Doctor Halsey. Since then, I have experienced a lifetime of combat. Through thirty years of war against alien aggressors... I have always known my fate. I knew someday I would die in battle. But now that it is here... now that it is time to die... I find I am not ready.	„
	~ John.

Background

John was born on the colony world of Eridanus II in the city of Elysium. From an early age, he was recognized as the physical ideal for a soldier. Before he was even seven years old, he was one of 74 other children to be kidnapped by the UNSC and turned into the ultimate killing machines via the SPARTAN-II program. The children were taught history, military strategy, weapons and received advanced physical training. It was here that John got a new name - John-117. He, alongside a small group of other children, were sent on training missions placed in the wilderness, such as Reach's forest. He quickly showcased strategic thinking and was promoted to squad leader after impressing both his peers and the UNSC officials.

At the age of 14, the child soldiers underwent dangerous SPARTAN-II augmentation procedures, which managed to kill 30 and physically disable 12 of the trainees. John was one of the 33 Spartans to survive the augmentation, becoming superhuman in every meaning of the word - their strength was increased, their reflexes became faster and their bones became almost unbreakable. Shortly after the procedures, the Spartans were sent to the Atlas battleship to recover from it in a microgravity environment. However, the peace would not last, as five ODSTs engaged John in the boxing ring, taunting the young soldier. The resulting fight ended in the deaths of two of the troopers, greatly injuries the remaining three. This would be the event that would make the SPARTAN-II program famous across the army.

Being a great leader and a powerful soldier, John was sent on multiple missions, proving to be the best of the best - not in speed or strength, but in bravery... And luck.

Soon enough, John-117 received the rank of Master Chief Petty Officer, gaining at the same time his nickname - Master Chief. He was equipped with the Mark IV Mjolnir armor and, a short time later, paired up with a UNSC Cortana. Together, they completed multiple training courses and missions, growing closer with each one.

Powers & Abilities

• Spartan Enhancements:
  • Carbide Ceramic Ossification: Bones are enhanced via grafting materials onto skeletal structures.
  • Muscular Enhancement Lining: Muscles were enhanced, allowing them to work harder without tearing apart the Spartan's skeleton.
  • Pulmonary Polymer Lining: Increases oxygen intake and retention, helps process toxins from the air and allows Spartans to breathe certain non-oxygen atmospheres for up to an hour.
  • Corneal Implants: Increases perception and grants increased night vision. Allows the Spartan to spot targets using Active Camouflage.
  • Cardiac Implants: Strengthens cardio-vascular tissue and increases maximum heart rate to safely allow massive adrenaline flow without the risk of stroke or heart attack.
  • Artificial Pancreas Implant: Allows the Spartan's body to extract the maximum amount of nutrients and carbohydrates from food with minimal waste.
  • Artificial Platelet Injections: Enhances the body's ability to slow bleeding and clot wounds.

Weapons & Equipment

• MJOLNIR Powered Assault Armor: Master Chief iconic armor has Brain linked reactive circuits, force multiplying circuits, titanium alloy plating, resistant to heat, has a motion tracker, a 5 second regenerating energy shields, and weighs 1000 lbs.
• UNSC Weapons:
  • M6D Magnum: A semi-automatic, recoil-operated, magazine-fed handgun and the standard personal sidearm of all branches of the UNSC post-2555. This weapon is surprisingly effective at reasonably long distances, proving its universal value in the field. Has a range of 400 feet and a scope of 2x.
  • M6G Magnum:
  • M7 Submachine Gun: A fully automatic UNSC submachine gun that fires from a 60-round magazine which is placed horizontally on the left side of the weapon. Has a range of 155 feet.
  • M9 Fragmentation Grenade: A high-explosive, dual-purpose explosive device that is effective against both heavy infantry and light armored vehicles. It's also fitted with a timed fuse that activates after striking a hard surface and modeled in a convenient throwing shape. Has a kill radius of 16 feet.
  • MA5C Assault Rifle: A magazine-fed weapon designed for close-quarters combat with lethal efficiency, regardless of hostile environmental conditions or duration of use in the field. Has a rate of fire of 650 RPM.
  • BR55 Heavy Barrel Service Battle Rifle: A gas-operated, magazine-fed infantry rifle proven to be an extraordinarily versatile weapon for a wide variety of ranges. Has a range of 3100 feet.
  • M90 Shotgun: A pump-action shotgun that has a lack of a pistol grip might be a downside in military combat, but this allows the user to hold the shotgun with one hand comfortably. It has a spread of 15 pellets and carries Soellkraft 8-Gauge Shells for ammo.
  • M41 Rocket Launcher: magazine-fed heavy weapon that fires a range of guided and unguided munitions. Has a reusable launcher with smart-linked fire control module and a disposable magazine holding two 102mm high explosive anti-tank rockets with a scope of 2x.
  • SRS990-S2 AM Sniper Rifle: A magazine-fed heavy weapon that fires a range of guided and unguided munitions. Has a range of 7545.9 feet and has a night-vision mode
  • M6 Spartan Laser: A shoulder-fired, smart-linked high-energy laser weapon used in an anti-vehicle role which produces a powerful microsecond-long pulse of energy capable of burning through thick plates of metallic laminates, nanocomposites, or hardened steel with only a 5 shot limit.
• Covenant Weapons:
  • Type-25 Plasma Pistol: Has a semi-automatic firing mode that emits deadly packets of superheated plasma capable of quickly degrading dissipative energy shields or vaporizing flesh. It also has an overcharge mode that emits a much larger bolt of plasma with a devastating short-range EMP effect that can disable electronics and vehicles on impact.
  • Type-25 Plasma Rifle: Fire in sequence, discharging superheated plasma from the charging and accelerator poles. Though extremely efficient, a significant amount of waste heat is still produced, forcing the wielder to fire short, controlled bursts or risk overheating.
  • Storm Rifle:
  • Type-51 Carbine: A compact medium to long-ranged infantry weapon that fires ballistic projectiles laced with radioactive isotopes instead of directed energy blasts. The ballistic impact alone is enough to eliminate an enemy, but the carbine’s projectiles are designed to poison the target if the impact is insufficient.
  • Spiker:
  • Needler:
  • Fuel Rod gun:
  • Brute Shot:
  • Concussion Rifle:
  • Type-1 Antipersonnel/Plasma Grenade: An energy-based explosive stored inside a smart-matter casing programmed to irrevocably stick to infantry targets. When activated, the grenade begins to vent its coolant, which destabilizes the small plasma generator at its heart. The resulting explosion is devastatingly effective, particularly against shielded infantry.
  • Type-1 Energy Sword: A close-engagement weapon intended to express its owner’s personal skill, clerical honor, and combat viability.
  • Gravity Hammer:
• Forerunner Weapons:
• Special Equipment:
  • Overshield/Energy Shielding: Enhances the personal energy shield around Master Chief's armor, leaving him nigh-invulnerable to damage.

  • Radar Jammer: Scrambles nearby players' motion sensors by creating a multitude of false dots on the radar of everyone within range.
  • Regenerator: Emits a small, green field of energy which restores Master Chief's shield as well as those of anybody near you, including enemies, for fifteen seconds.
  • Deployable Cover:
  • Power Drain: Creates a short-range electromagnetic pulse (EMP) effect, which interferes with all electronic equipment within the radius of the pulse. It is designed primarily to interfere with common varieties of electrical field-based shielding, as well as the electrical components of vehicles.
  • Bubble Shield: A deployable equipment system that creates a spherical force field when activated.
