In 2517, John was a six year old human living with his loving mother and father on the Earth colony Eridanus II until he was kidnapped by the UNSC and replaced by a clone to be a Spartan, a super soldier helping the UNSC in the intergalactic war against the Covenant, an army of dangerous aliens trying to turn on a device that will destroy all organic life in the universe called Halos. In his training, he was said to be VERY lucky and had great intellect. After his regular training, he was injected with a super steroid, completely making his health, speed, reflexes, physical, and mental strength dramatically 10x faster, stronger, and overall better. 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.
