You may find this difficult to believe, what with the already overstuffed cast of characters in ‘Batman vs. Superman,’ but there’s yet another comic book character who will be making an appearance—however brief—in Zack Snyder’s upcoming superhero super-face-off film. In addition to Batman, Superman, Wonder Woman, Aquaman, Cyborg, The Flash, Lex Luthor, and the rumored appearance of Doomsday, it’s now being reported that an old Batman foe will also be making a cameo.

Lex Luthor is a pretty bad dude, but he can’t take on the responsibilities of total evil world domination alone. According to Badass Digest, one of his many agents is Anatoli Knyazev, also known to comic book readers as KGBeast, a Batman villain who initially appeared in 1988's ‘Ten Nights of the Beast.’ KGBeast was, as you may have guessed, an enhanced KGB agent and lethal killing machine. He was sent to the US on a mission to kill 10 targets, and ultimately fought Batman until they reached a stalemate, leaving the baddie to hang from Batman’s rope until KGBeast cut off his own hand to free himself. He later replaced it with a cybernetic gun.

At least it’s just a “cameo” because we honestly cannot imagine how another character could manage to be given more than one or two minutes of screentime, let alone entire lines of dialogue alongside that roster. What was initially a ‘Batman vs. Superman’ film has now essentially become the ‘Justice League’ prequel. (And Snyder is also including the death of Bruce Wayne’s parents! In the midst of all of this!)

The report also confirms that Doomsday is indeed appearing in ‘Batman vs. Superman,’ which was before only previously rumored. How many characters and plots can they fit into this movie? We’ll find out when ‘Batman vs. Superman’ hits theaters on March 25, 2016.
