I theorized not too long ago that in the new Batman movie in which mah boo Tom Hardy is cast and the Riddler is NOT the enemy, I think the new villain should be (and I’m crossing my fingers it is) Hush.
Tom Hardy would be an awesome Hush and as upset as I would be seeing his face all bandaged up for…oh, I’ll say 60% of the movie, he would still play him amazingly. Nolan does set his Batman in a more realistic tone then say Tim Burton or Joel “Ruler of trying to forever make Batman a Joke” Schumacher and Hush seems to fit that more realistic feel. If you don’t know who Hush is, I suggest you read up and see why my theory fits.
BTW I will totally be gloating if I’m right.
My second theory would be Black Mask, but that too would be a shame.
