Though it is highly unlikely that Rocksteady would compromise the identity of their titular character, it would at least be nice to get some hint as to who this new villain could be. Added to the DC canon specifically for the gaming series, there is a great deal of speculation as to who the masked nemesis could potentially be as most believe the villain to be a pre-existing character in a new guise. Popular theories revolve around the character being one of the so-called anti-Batmen, or villains who are a dark mirroring of Gothams guardian. Villains who have been short-listed as Arkham Knight suspects include Bruce Waynes childhood friend Hush, Bruces psychopathic son with Talia al Ghul; Damian Wayne, and genius super-villain Prometheus.
