Red Mist.

Mark Millar mentioned that he wants your sidekick in the next comic to be called The Cunts?

He wants something to be The Cunts, he wants the name The Cunts somewhere in the comic. And he wants to change my name to The Motherfucker. So I become very evil, which I'm game for. But who knows, because Mark talks, and we won't know until he puts it on paper, what he's going to do. He could come up with a totally genius new idea that we've never heard of.
