5) KGBeast
In Batman V Superman: Dawn of Justice, Lex Luthor’s main henchman is a Russian mercenary whose general role is to repeatedly threaten Lois Lane and kidnap Martha Kent. When Bruce Wayne is investigating his identity, he finds out his name his Anatoli Knyazev.
This is the real name of C-grade Batman villain KGBeast. The film character (as played by Callan Mulvey) is pretty different from his comics counterpart, however. While the movie’s version likes to dress up as janitors to surprise his kidnap victims, KGBeast wears a red and blue outfit and, oh yeah, has a gun for an arm.
Again, the character might be being set up for a proper KGBeast appearance later down the line, but the chances are that his inclusion here was simply a nod for the fans in a film that was packed full of them.
