Created by Dr. Leonard Price in order to defeat Evil Ernie, as Operation Crippler for the president of the United states before Price assassinated him, Rashad was killed during the psycho-plague and implanted with a control chip and some of Evil Ernie's arcane energy and his body enhanced for combat.
After Price's many attempts to reanimate him it was Lady Death's aborted transportation to Earth, causing the Pandora Effect, that finally raised him from death. He was completely uncontrollable by Dr Price and left without facing Ernie.
