The man's name is Coffin, and he's the newest member of the Chaos Riders. Last time he rode into town, he took X's left eye as a souvenir. This time around, he's not going to settle for just an eye. X builds toward its inexorable climax -- and a startling revelation about our one-eyed mystery man -- in X #25.
