That’s the strong rumor that is now circulating around the internets. Apparently Scottish comic book writer Mark Millar knows who it is, and went to his Twitter to drop some hints. Here’s what he says:
Oh, wait. Con gossip: I know who the villain(s) are in Batman 3 and the big scene outside Gotham sounds awesome. Totally timely locale.
Also, it has been confirmed that Batman 3 filming will begin in New Orleans. After deliberating with my friend Kate, who is a huge comic book fan, it turns out that Killer Croc is actually a croc wrestler from where? NEW ORLEANS! And apparently he has scaly skin too. Kate and I both think that this character would be awesome for this universe, and we can’t wait to see what happens!
