1st Appearance of Ghost and The Creator.
Monster partially appears in a one-panel cameo.
*Someone brutally murdered Ghost, and she's not happy about it. She's an apparition with an attitude, a taste for revenge, and nothing to lose. Anyone who crosses her is likely to end up dead. That includes X -- he makes the mistake of going after a man whose life Ghost wants for herself. He finds out the hard way that it's tough to crush the bones of someone who doesn't have any, it's tough to blow someone to bits when they have no substance, and it's tough to kill someone who's already dead.
He also finds out that Ghost has some nasty habits. And two of them are Colt .45s. *Source: darkhorse.com
