Hmm, interesting posts!
Black Canary seems to be the most popular thus far. Curently, in The New 52, she has reassembled her all-female "Birds of Prey" fighting force. Recruits include Poison Ivy, Katana, and new character Starling.

Speaking of
Poison Ivy (pictured here in the new Birds of Prey troupe) - She BETTER be in this game lol

Another popular chick is
Starfire. She is currently a member of the "Red Hood and The Outlaws" team featuring Red Hood, Arsenal, and herself. I can dig her. She reminds me of Sindel - which is a good thing (I heart Sindel). I also love her red hair color.

Starfire is a bit over-sexulized in The New 52 as you can see. I have a feeling NRS will incorporate some of this (titties and heels) in her character design - calling it now

. Sex Sells.
Zatanna sports a new "every-day" look in The New 52. She is a stage magician and a member of the newly formed Justice League Dark alongside John Constantine and Madame Xanadu. They are assembled to defeat Enchantress.
Powergirl and
Huntress. Their re-launch just started last month with the comic book titled "World's Finest"! Huntress is Helena Wayne, daughter of Batman and Catwoman in the alternate universe know as Earth 2. The 2 women have been accidentally exiled from Earth 2 and brought into the real DC Universe. They fight alongside each other in the DC Universe.
Catwoman! Saved the best for last! She's the same ol' Selena Kyle in her relaunch. She straddles the crap out of Batman in Catwoman #1 LOL

She, like Starfire, is a very sexual character in The New 52. But for Catwoman - it fits imo. I hope NRS max out her sex appeal in this new game. They did her very well in MKvsDCU.
Thanks for the input - keep the discussion going!
