The Deadpool movie won’t be all Ryan Reynolds cracking wise and destroying highways. We’ve known for some time that Game of Thrones actor Ed Skrein is in the currently filming Marvel Comics adaptation, but we now have confirmation of his character, and he’s gonna bring some trouble for Reynolds’ Wade Wilson. Skrein is playing the film’s villain, Ajax, a character that comes directly from the comics.

In the source material, Ajax begins as a man known only as Francis who acts as an enforcer at the hospital in which the Weapon X program is underway. Having had his nerves removed, Francis serves to reign in the “washouts” of the program, including Wade Wilson. But when he tries to exterminate Wilson after the latter’s Weapon X surgery goes wrong, Wilson instead turns the tables, seemingly killing Francis. I say “seemingly” because Francis reappears having taken the name “Ajax,” seeking out and killing all former members of the Weapon X program, and bent on revenge against the man who tried to kill him.

We know that Deadpool will get into the titular character’s origin story, which finds Wilson gaining his powers after experimental surgery to cure his cancer goes wrong, but the official synopsis says that Deadpool “hunts down the man who nearly destroyed his life,” so it’s possible Ajax is instead the hunted in the film.

Skrein—who played Daario Naharis in Game of Thrones’ third season before being replaced—confirmed that he’s playing Ajax on Twitter with a photo from set. In addition to Deadpool and Game of Thrones, Skrein stars in the upcoming The Transporter Refueled.

Check out Skrein’s photo below. Directed by Tim Miller, the film also stars Morena Baccarin as Vanessa Carlysle, T.J. Miller as Weasel, and Gina Carano as Angel Dust. Deadpool opens in theaters on February 12, 2016.
