John-117 (Earth-2042)

"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-117

Master Chief Petty Officer John-117 is a SPARTAN-II supersoldier of the UNSC Navy's Special Weapons division. He served as one of the most important figures of the Clone Wars. After over thirty years of active duty, he was one of the most decorated war veterans of the Galactic Republic Space Command. By 20 BBY, John's career service vitae recorded two hundred and seven ground engagements against the Insurrectionists, the Covenant, and eventually the Confederacy of Independent Systems in which he had participated. By 20 ABY, he had completed two hundred and nine military operations, including one hundred and thirty-six full campaigns; more than anyone other military personnel on record at the time. Though John has commanded nearly every SPARTAN-II at one time or another, the lion's share of his career has been spent as fireteam leader of Blue Team. His actions during the Clone Wars earned him every major service medal and combat award, as well as several dozen civilian honors.
