Batman has one of the darkest and most interesting histories in DC Comics. Historically, his books have been a healthy combination of crime noir, Gothic horror, and action, with touches of science fiction and the supernatural added in. Throughout Bruce Wayne's tenure as Gotham's Dark Knight, the hero has fallen prey to his enemies many times and has grown accustomed to death.
