Many fans were shocked when the third full-length trailer for Batman v Superman: Dawn of Justice revealed Doomsday as one of the main villains. Ever since, people have been wondering about the identity behind the person who brought this CGI monstrosity to life. Today, that actor has come forward to confirm his part in helping to create Doomsday for the big screen.

The man behind Doomsday is none other than Robin Atkin Downes. And he already has a quite storied history with the Batman franchise. On the animated side of things, he first voiced characters for the 2008 Batman: The Brave and The Bold TV series, playing such DC villains as Firefly and the Weather Wizard. In 2011's Batman: Year One, he played District Attorney Harvey Dent. He voiced Oliver Queen in Batman: The Dark Knight Returns, Part 2. Most recently, he voiced several characters in this year's Batman: Bad Blood, bringing http://movieweb.com/alice-through-looking-glass-movie-trailer-2016/The Mad Hatter, Jervis Tetch and Electrocutioner to life. He also portrays The Master in FX's hit horror series The Strain, and Cham Syndulla on Star Wars Rebels. Here's what Robin Atkin Downes had to say about playing Doomsday.

"Very proud to release that I helped bring #Doomsday to life in the upcoming @BatmanvSuperman #Dreamgigs"

With Doomsday being a mostly CGI character, several teams of people will be responsible for fully rendering the creature for the big screen in Batman v Superman: Dawn of Justice. Robin Atkin Downes will be giving voice to the villain, and lending a Mo-Cap hand in terms of perfecting his movements. The process is described as being similar to what Deadpool did with Colossus. While Stefan Kapicic provided the voice and some of the Mo-Cap work, other actors and VFX supervisors were equally responsible for making that character what it eventually became.

Man of Steel star Michael Shannon has confirmed that he participated in Batman v Superman: Dawn of Justice, playing the cadaver of his doomed villain Zod. It has been rumored that Doomsday is created from the body of Zod. Though, it isn't know if Michael Shannon has contributed anything to the performance of Doomsday as we'll see him on screen. None of the other VFX team has been named at this time. Nor is it known if Doomsday will be able to speak intelligently, or if he will only be able to communicate in grunts and roars.

Doomsday is said to not be the only big villain making an appearance at the end of Batman v Superman: Dawn of Justice. Though, we're not quite sure who might make an appearance during the climatic third act of the movie. We know that Lex Luthor is climbing into his Kryptonian armor at some point, and that he brings Aquaman into the fight. We're also supposed to see the rest of the Justice League. But it's unclear in what capacity. However it shakes out, at least we know there is a human heart beating behind the CGI exterior of Doomsday. And that heart belongs to one Mr. Robin Atkin Downes.
