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?

~Cortana to John at the start of Halo 3.


John-117, better known as Master Chief, is a Spartan-II 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.

Attack Potency: Wall level without MJOLNIR or weapons (Accidently killed two ODST soldiers), Small Building level with MJOLNIR physical blows; (Can KO other Spartans and other comparable troops with three punches). Street level to Wall level with most weapons; Small Building level to Large Building level with various heavy weapons and demolition explosives, (Incineration Cannon is this strong); Town level with Medium Fusion Destructive Device (Approximate yield of 15 kilotons), Large Town level+ with Fury Tactical Nuclear Weapon (Approximate yield of just under 1 megaton), City level with HAVOK Tactical Nuclear Weapon (Approximate yield of 30 megatons); Island level with Super MAC Blast.

Speed: Superhuman travel speed (Ran half a kilometer in 17 seconds (Nearly 106 kilometers per hour but tore his Achilles tendon doing it; he is probably faster now since SPARTAN augmentations supposedly improve with maturity), Supersonic combat speed and reactions (Can react to bullets and plasma projectiles, and has barely dodged handgun fire at point-blank range, viewed combat with the ODST's in slow motion, has reacted to Promethean Lancer Knights), Speed of Light attack speed with Spartan laser, (although, it requires 5 seconds to charge).

Lifting Strength: Class 1 without MJOLNIR armor (Can deadlift at least 3 times his own body weight, deadlifted 500 kilograms as a test); Class 10 with MJOLNIR armor (Can deadlift at least 5 tonnes, dragged a large antimatter warhead around with little effort, casually flips overturned 3.25 ton Warthog jeeps singlehandedly, moved a large stone monolith while also fighting back the pain of losing half of his left arm, is somewhat stronger than the average Elite and somewhat weaker than the average Brute).

Striking Strength: Wall Class without MJOLNIR armor (A 14-year old John accidently pummeled several ODSTs to death without even realizing it and launched one of them 30 feet with a few punches, Small Building Class with MJOLNIR armor (Can barely deflect large anti-tank missiles and damage tank shells with his hands; smashed through rock this big with a Spartan charge, out wrestled a Brute, his physical superior).

Durability: Wall level without MJOLNIR armor. (John, at the age of 14, had the confidence to survive a 30-meter fall with little to no injury); Small Building level with MJOLNIR armor plating (Can withstand all sorts of human and covenant rifles; Mark V MJOLNIR tanked a splash effect of Onyx Sentinel Beam, can take hits from other Spartans, survived a 2 kilometer fall, including the heat and impact, while riding on a ship's hull and locking down his armor's servers); at least Small Building level+ with MJOLNIR energy shields (Took a direct hit from 343 Guilty Spark's Sentinel Beam; which vaporized a Kig-Yar), possibly up to Building level (Can barely survive one hit from Fuel Rod Cannon, 1.5 Gigajoules); Building level with Overshield, Drop Shield and Deployable Cover (Roughly two to three times stronger than MJOLNIR shields); At least Large Building level with Armor Lockup and Invincibility (Renders him virtuously impervious to all previously mentioned attacks); probably at least Small City level+ with Bubble Shield (Repels all previously mentioned threats except vehicle impacts and melee attacks, withstood a several Megaton Nuclear explosion); Likely City level with Cortana's bubble, (Withstood a near point-blank nuclear detonation of a Havok Tactical Nuke that was aimed at Ur-Didact, although it's unknown whether or not the normal Bubble Shield is as strong), can likely expect a similar level of performance from the Hardlight Shield (Except monodirectional rather than omnidirectional).

Stamina: Superhuman (Can last much longer on the battlefield much longer than any of the UNSC marines and ODST soldiers, has the pain tolerance to continue fighting even when losing an arm. Stamina is further enhance 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, at least two kilometers with sniper rifles; up to a dozen kilometers with tactical nuclear weapons and Super MAC Blast.

Standard Equipment: MJOLNIR Powered Assault Armor, MA5 assault rifle, M6 series pistol, M9 fragmentation grenades; can be assumed capable of operating virtually any weapon with deadly skill. Cortana (Artificial Intelligence), although it varies to where he is deployed and the time period.

Intelligence: As Doctor Catherine Halsey's favorite Spartan, John showed exceptional promise as a 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. In addition, 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 despite the fact that the Prometheans had spent thousands of years subjugating other civilizations.

Weaknesses: Chief's energy shields must recharge after taking an extended beating, leaving him open to damage for a few seconds. 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 blunt force trauma to the chestal area and is dependant on MJOLNIR plating durability rating against physical blows; melee attacks on that level might cause John to get crushed by his own armor. MJOLNIR shields and armor are very susceptible to electricity and plasma weaponry. Bubble Shields only protect from outside projectiles and explosions; all infantry troops and vehicles can easily run right through them.

Note 1: Most of Master Chief's strongest weapons, including tactical nukes, MAC Blast, and Cortana, are considered outside help and must be specified by the OP for them to be used in VS Threads.

Note 2: Standard 9-C to 9-B weaponry generally ranges from pistols to rifles on both the UNSC and Covenant varieties; 9-A to High 8-C heavy weapons include Rocket launchers, Needlers, Fuel Rod, and most Forerunner weaponry.
