All I want is Poison Ivy. There is so much potential for her as a fighting game character.
There are probably more demanded characters and other Batman characters that would come before her too which sucks! I'll deal though.

I could see her being potentially interesting gameplay wise. Unknown was great in TTT2. She kinda has some elements that could be represented by PI to be just as cool.

Fix the damn title. I almost made another joke about it.

I like the roster, but I'm honestly not deep into comics. Thing is, I always love to see people and things I'm not familiar with in these types of things. My excitement over Captain Marvel was unprecedented and I loved his gameplay. I want to see more obscure characters, this coming from the "average joe". Learning about the various obscure Batman villains in Arkham Asylum/City was one of the highlights of the game.
