Major Upgrade was a villain. He was a Devisor that made weapons and Power armor amongst other things. The last thing he made was a nanite-based computer chip that automatically upgraded and repaired any devise that he had made. He tested it on his android butler, which was upgraded and went Westworld on him, killing him and twelve others before the STAR League stopped it. The Knights of Purity were sent in to clean up and Mauler stole the Power Armor and weaponry.
