Bio Edit

Master Chief Petty Officer John-117, a.k.a. Sierra-117, is a leader of the groups of space marines in service of the UNSC (United Nations Space Command) known as the SPARTAN-II Program. He has seen countless battles over the years, both against the human Insurrectionist and the Covenant.

Kombat Characteristics Edit

Powers and Abilities Edit

Throughout his career, John has shown a preference for the standard-issue set of the given Mjolnir armor generation used at the time. His Mjolnir armor is invariably colored olive green with a gold visor, which has made his appearance iconic among humans and Covenant alike. At some point during his four-year cryosleep aboard the Forward Unto Dawn, Cortana used nanomachines to repair and physically alter John's MJOLNIR Mark VI armor. Cortana also rewrote the suit's firmware, altering the HUD as well as improving the suit's shield-recharge rate and its compatibility with Covenant and Forerunner armor plugins. His upgraded suit displays the Braille characters "117" on the left of the breastplate.

Immediately after the Mission to Installation 03, John received an upgrade for his Mark VI armor from ONI's Watershed Division, bringing it into the GEN2 line of Mjolnir PAA. The armor still looks like his updated GEN1 Mark VI, the most prominent difference being a redesigned bodysuit. His armor also now lacks the prominent gash on the chestplate and his helmet is intact again after the Didact severely damaged it during Blue Team's battle against him on Installation 03. His visor was once again cracked by Spartan Jameson Locke on Meridian.

John's old Mark IV helmet is used as the "last thing" that SPARTAN-IV candidates see before beginning their evaluation and preliminary augmentation cycle.
