Constantine Potter: Order of the bloody Phoenix

He's the one who steps from the shadows, all trench coat and arrogance. He'll drive the demons away, kick'em in the bollocks, leaving only a nod and a wink and a wisecrack. He walks the path along because, who would be crazy enough to walk it with him. Constantine gets thrown into the Potterverse and begins to help Harry to kick Voldemort in the bollocks. M for bloody language.
