DC Comics supervillain Doomsday may be making an appearance in upcoming film “Batman v Superman: Dawn of Justice,” which is directed by Zack Snyder and will reach theaters on March 25, 2016. And it looks like Batman could be the least of the Man of Steel’s worries.

Film journalist Umberto Gonzalez mentioned that Superman’s (played by Henry Cavill) nemesis would appear in the upcoming action flick in his "Shanlian on Batman" podcast on Saturday. Known as the “ultimate killing machine,” Doomsday was born during prehistoric times on Krypton, also the native world of Superman.

Rumors that Doomsday would appear in the film have been circulating since last year. The bad guy isn’t your everyday nemesis. In the comics, Doomsday defeats the entire Justice League in only a few minutes, and then engages in an epic battle with Superman in front of the Daily Planet building in Metropolis that results in both of their deaths. Could this mean that Superman, played by Henry Cavill, could face his demise in the film?

Well, not necessarily. Just because Doomsday defeats the superhero in the comics doesn’t mean that he’ll finish off Cavill’s character. “The Justice League Part One” will reach theaters in 2017, so it wouldn’t make sense to kill off Superman. Still, the appearance of Doomsday as a supervillain could mean that Snyder places him as the nemesis in several movies – much like Loki in the Marvel “Avengers” film series.

A little backstory on Doomsday -- his birth on Krypton took place 250,000 years ago, during a time when the planet was incredibly violent. Bertron, an alien scientist, released a humanoid infant into the destructive world, only to see him killed quickly. The baby’s remains were collected and used to clone a stronger version. This process was repeated for decades to accelerate the creature’s evolution. Each death was recorded in Doomsday’s genes, resulting in his hatred of all life. Yes, Superman should be a little afraid.
