Kylstar was a crystalline alien.

He acquired weapons - powerful heroes - from across the galaxy to overthrow the brutal dictator on his planet. From Earth, he took Superman, Captain Atom and Major Force. Of them, only Major Force agreed with Kylstar's plans. However, as only two others had agreed, Kylstar felt he did not have enough power to defeat his enemies. To warm up to the challenge, he decided to conquer the universe first.
