Not much is known about the Iron Skull, just that he showed up one day at the gates of Castle Destro and claimed that he was a distant relative of Destro's. That was after he took out a squad of IG's. Iron Skull doesn't say much; his actions speak louder than words. He once forced a would-be buyer to pay twice as much for weapons from Destro by breaking all four limbs of the buyer's bodyguard. Destro likes Iron skull for his brutal nature and quiet disposition. Destro assigned Iron Skull to the IG Assult Squad for his ability to be persuasive.
