Master Chief is the main protagonist of the Halo franchise. He appeared in the 18th episode of Death Battle, Master Chief VS Doomguy, where he battled Doom protagonist Doomguy.


In 2517, John was a six-year-old human living with his loving mother and father on the earth colony Eridanus II. One day, he was kidnapped by the UNSC and replaced by a clone to be a Spartan super soldier. His job was to help the UNSC in the intergalactic war against the Covenant, an army of dangerous aliens trying to turn on devices that would destroy all organic life in the universe called Halos. In his training, he was said to be VERY lucky and had a great intellect. After his regular training, he was injected with a super steroid, boosting his health, speed, and reflexes dramatically, as well as making him 10x faster and stronger, both physically and mentally. After reaching the rank "Master Chief Petty Officer", he led the other Spartans to defend the humans from any threat and gained a full body, half ton armor suit that was near indestructible.
