The first man to wear this uniform was David Wexler, brother of Larry Wexler (Black Cat). David resided in an other-dimensional reality and Larry grew up not even aware of his brothers' existence. Strangely, both men become costumed adventurers. Eventually, David travelled to our reality where the brothers finally met. David was slain by Larrys' arch enemy, the Falcon. Killer Cat is the super-villain formerly known as the KILLER. He has faced Lon of Venus as well as Black Cat. He adopted the Killer Cat uniform and joined Computerons' Future Four, wishing to reside in the 21st century instead of his own era.
