Tomorrow, July 21st at 5:00PM, a Comic-Con panel for Batman: Arkham City is being held at the Hilton San Diego Bayfront Hotel. Mark Hamill will be there. But more importantly, so will a new Batman: Arkham City character.
At the moment, that's all we know. Someone will be added to the already growing roster of characters. Will they be playing for the villains team or the hero team? At E3, Rocksteady Studios revealed Catwoman and the Penguin, and Robin and the Riddler were outed a couple short weeks ago. But who's next?
Give us your best guess below, and look out for the news coming out of our week-long Comic Con coverage.
