Batman, or Bruce Wayne, was a notorious superhero.
In Reality Z-25 31-H, Alicia and Babs once watched some piece of media featuring Batman on their TV screen while waiting for Kelly to return from her trip to Hell. (COMIC: Journey Out Of Misery)
When Wayne Bruce, a man who had been mutated to gain bat-like traits, applied for a job at the Multidimensional Finders Service, he found himself dismissed because Jenny Over-There and the Man in Grey thought he looked suspiciously like Batman. (PROSE: Open Sourcing)
