5. The Batmaniac

Turns out this one is so obscure I literally could not find an image of him anywhere on the internet.

Here’s one so obscure that he doesn’t even have a dc wikia page (although hopefully someone will change that.) The Batmaniac appeared in a three issue arc lasting from Detective Comics # 622 until # 625.

In the arc, a comic book company began publishing a Batman comic book, containing tons of speculation about Batman’s true identity. A mentally ill vigilante loved the comic, and became convinced that he was the Batman, painting a bat on his face and shotgunning criminals in the streets. As a result, the writer of the comic killed off “Batman” and ended the series, horrified by the influences his actions had.

Batman, meanwhile, tracked down and beat up the Batmaniac, ending his reign of terror for good. Track down those comics, if you can, they’re super fun and totally underrated. John Ostrander really knew how to write a Batman comic.
