Batman (Earth-Two)

The Batman of Earth-Two is a parallel version of the DC Comics superhero, who was introduced after DC Comics created Earth-Two, a parallel world that was retroactively established as the home of characters whose adventures had been published in the Golden Age of comic books. This allowed creators to publish Batman comic books while being able to disregard Golden Age stories, solving an incongruity, as Batman had been published as a single ongoing incarnation since inception.
