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 generation 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, The Created, and The Banished. My best friends and teammates are Kelly-087, Linda-058, and Fred-104, as well as my fellow SPARTAN IIs.
