Lex Luthor is another major villain in the movie.
Doomsday will allegedly be Lex Luthor's "muscle" like how Darth Vader was Grand Moff Tarkin's "muscle" as Lex Luthor is not a threat unless he is wearing some sort of armour, reported Aceshowbiz.
Neither Zack Snyder nor Warner Bros has, however, announced that Doomsday will make an appearance in "Batman v Superman: Dawn of Justice".
Starring Ben Affleck, Henry Cavill, Amy Adams, Jesse Eisenberg, and Gal Gadot, the superhero film is set to hit theatres in the US on March 25, 2016.
