An evil scientist who wanted to create an army of supersoldiers, and conquer the world.
He cloned Captain from a single sperm cell, that Captain used to have. He aimed to make Captain have sex with a superpowered alien chick, who would then give birth to a supersoldier.
His plans were thwarted, he accidentally sent Captain back to his own time (which should complicate things for him, since he wasn`t taken from the past in the first place…) and died when his space HQ exploded.
