According to Latino-Reviews (sometimes they’re on the money, sometimes not), rumors have been circulating about what supporting and villainous characters might be making their way into Batman V Superman: Dawn of Justice.
So who are these characters? One possible character is bat-baddie, Victor Zsasz, who you might remember was in Batman Begins for a minute and was the first nut-jobs you beat in Arkham Asylum. He’s not exactly one of Batman’s top threats, with his gimmick being that he just makes cuts on body for each of his victims.
Other characters include Morgan Edge, a Superman foe who was a mob boss; David Cain, a master assassin and Mercy Graves, Luthor’s personal assistant who can also kick a lot of butt when need be.
Lastly — and someone I have a bit more knowledge on than whoever the hell Morgan Edge is — is Amanda Waller. Amanda Waller is usually depicted as one of the higher-ups of Cadmus in the DC universe. Cadmus is essentially an organization in the government that is suppose to keep superheroes in check, but are usually douchebags about it. You might remember Amanda Waller from the exceptional Justice League Unlimited series, or her small, unimportant role in the awful Green Lantern movie. This version of Waller is depicted as “a very stern and focused senator with an intimidating presence. She doesn’t trust Superman. At all. Sees him as a threat and comes up with a counter measure that I won’t spoil.”
Not official words on any of these characters appearing or who are cast to play them.
