Master Chief Petty Officer John-117, or more commonly known as the Master Chief, is a Spartan-II commando of the UNSC Naval Special Warfare Command who became one of the most important UNSC heroes during the Human-Covenant war.
The Master Chief is a towering and faceless biochemically and cybernetically-enhanced supersoldier, raised and trained from an early age to be a weapon; he is almost never seen without his green-colored armor and helmet. He is commonly referred to by his naval rank, rather than his given birth-name or serial-designation.
