Now IMDB itself is full of fact and just plain fiction, so it’s not credible enough. Warner Bros has said this is ”inaccurate” info to their knowledge.
”To our knowledge, what you asked about is inaccurate information. We are not yet discussing details for the sequel,” Warner told Kotaku. It’s possible that if Robin did receive some voice acting that it could just be for a quick cameo or two for fans.
The other possibility thrown around is that it would set up a co-op mode quite well, having both Batman and Robin smacking crime in the face. Here’s the IMDB listing, which shows Martella as Robin’s voice for ‘Batman: Under the Red Hood’.
Arkham Asylum had the Oracle but kept her role strictly off screen and as a way for Batman to be fed info on what’s happening on and around the island. What do you hope Rocksteady has done with Robin? Maybe you prefer his later persona - Nightwing?
Batman: Arkham Asylum II releases on Xbox 360, PS3 and PC later this year.
