I have avoided the Marvel character Moon Knight because it looks so much like an attempt to create a Marvel knockoff of Batman. Many top comic writers and artists have turned the character into something unique. The most unique quality of Moon Knight is that he has three secret identities, a mercenary, a wealthy playboy, and a cab driver. Writers have developed this into the idea that Moon Knight is mentally ill and suffers from dissociate identity disorder.
Warren Ellis specializes in writing stories about odd loners who are hyper competent and possess skills far beyond normal people. Moon Knight is a perfect fit for his approach, alongside other Ellis titles like Transmetropolitan, Doktor Sleepless, Fell, Karnak, and Desolation Jones. Ellis expands on MK's multiple identities by giving him two new heroic appearances. As Mr. Knight he is a white suited detective who consults with the police in ways that the dangerous vigilante Moon Knight cannot. He also dons a suit of Egyptian shamanistic armor with a bird skull mask that allows him to punch ghosts. A fun dark take on a fringe Marvel character.
