This has me filled with joy. Over at Comic Book Movie, someone has posted pictures of what appears to be a magazine article for the upcoming fighting game. As you can see, it says the man who broke the Bat and the famous Superman villain will be part of the "well-stocked roster."
According to the description, Bane will serve as a powerhouse, focusing on grappling moves and raw strength. Basically, he sounds like an amped up version of Zangief. And as expected, Luthor will be in a power armor that will likely grant a whole variety of attacks including missiles and a defensive shield.
The website didn't provide a source for these images and again, this isn't technically confirmed, but it looks pretty legitimate to me. Also, does anyone else think Lex looks an awful lot like a certain A-list celebrity that enjoys saying yippie-ki-yay?
