History
A Native American who had a hard time finding work due to the discrimination against his people, Geronimo Jr. soon found a job as a construction worker. While working one day, Geronimo was approached by an operative from Black Ghost with a better job offer. Initially accepting it, Geronimo soon realized it was a trap, but not before he was abducted and taken to one of Black Ghost's laboratories, where he was converted into the fifth model of Black Ghost 00 Cyborg line, having his already impressive physical strength enhanced through cybernetics.

005 later escaped Black Ghost alongside the other models of the 00 Cyborg line with help from Dr. Gilmore, an ex-Black Ghost scientist. From their, the 00 Cyborgs dedicated their lives to bringing down Black Ghost and thwarting their plans of warmongering.
