I don't think i wanna see her in a handmade cat-domina costume. It doesn't feel protective enough, like for starters she uses it but then thru black market she buys a stealth costume that protects her and whatnot.
I really wanna see Joker as a crime boss with some great motive, but yeah the 1st comic villain we're seeing is Riddler.

Can't wait to see what he'll end up being! Maybe a Internet terrorist? I'm sure Johns won't do that stupid "make him like jigsaw!" kinda deal that people seem to suggest. -__-
