A new character reveal for Batman: Arkham Asylum debuts Poison Ivy. The villain list just keeps getting bigger and bigger. Who knows what the final listings should be. Personally I find this the best way to market Batman much like what The Dark Knight movie did, slowly give you bits and pieces before finally revealing the big show. Here it is for you to enjoy courtesy of IGN.

Batman Arkham Asylum will be releasing for the Xbox 360, Playstation 3 and PC later this year.
