Rampage is a genetically mutated cyborg supervillain who is the result of a botched military experiment on a US marine. He lost his right arm in a training exercise where he overestimated his strength and tried to catch a rocket-grenade. His arm was replaced with a cybernetic arm in hopes of rehabilitating him.
