The greatest sidekick in comic book history, Robin, could be making an appearance in the upcoming Arkham Asylum 2 if early cast listings are correct.
An IMDB listing for Rocksteady's sequel to Arkham Asylum confirms that Mark Hamill reprises his performance as The Joker, and he's to be joined by Two-Face as actor Bruce Greenwood takes on Harvey Dent and his alter-ego.
But the real news is the inclusion of Robin, to be played by Vincent Martella who most recently voiced Hope Estheim in Final Fantasy XIII.
