I am Master Chief Petty Officer John-117 of the UNSC Marine Corps. My service tag is S-117. I am one of the SPARTAN IIs, a group of augmented super-soldiers. In MJOLNIR Mk VI Gen 3 armour, I can sustain a heavy amount of damage thanks to my recharging energy shield. I have faced many enemies, such as the Covenant, the Flood, the Prometheans, and the Banished. I lead Blue Team, composed of my fellow Spartans and closest friends Fred-104, Kelly-087, and Linda-058.
