For your consideration in this contest I present, Casshan Robot Hunter or Robot Hunter Casshern as he is known in Japan. Originally created in 1973 by Tatsunoko for their animated series Neo-human Casshern. Casshan made it to american shores in a four episode ova condensed into a movie shown on the Sci-fi channel and on vhs in the early 90's. In resent years Casshan has made a comeback in multimedia. He was given a new anime: Casshern Sins, a overseas big budget live action movie, and he was a character in the Wii only fighting game Tatsunoko vs Capcom.
His origin is his father was a robotic scientst who built a unstoppable AI called the Black King or Buraiking Boss who feels to uphold his primary objective of saving the planet, humans must be culled and ground under his feet. Casshan's father and another partner were in the works of making an nano exosuit that would help turn the tide against the Black king and his robot armies, when an attack by the Black King's lackeys to capture the scientst ended up killing the partner and mortally wounding the then human Casshan. With his dying breath Casshan jumped into the machine that fused him with the experimental nano exosuit and that was how Casshan Robot Hunter was born, scourge of the Black King's army and the last hope for humankind.
This Casshan custom was made from:
HML Red Hulk series: Silver Savage figure body, LH Madman arms, ML series 10 Angel legs and hands, parts from a Casshern pvc statue, and some sculpting.

Thanks for looking.
