'Vampire Diaries' casts 'Supernatural' angel Sebastian Roché

" Supernatural's" Balthazar was an unfortunate casualty of the Season 6 finale after double-crossing Castiel ( Misha Collins), but luckily, CW fans won't have to wait long to see actor Sebastian Roché in another juicy role.

EW reports that Roché has been cast as "The Vampire Diaries" newest vamp hunter -- and he's a pretty formidable one, by the looks of it, because he makes even Klaus (Joseph Morgan) nervous. Perhaps the yet-to-be-named character specializes in hunting hybrids?

(By the way, there were reports that the character would be named Eric... but since "Heroes" star Jack Coleman is coming in as a character named Bill, Roche's character name will be changed so we don't get confused as to whether we're watching "True Blood" or "TVD.")

The role is recurring -- and it's not the first time "TVD" has snapped up a "Supernatural" alum!

"He is big, and he is bad, but I would dare not say if he is the true Big Bad or not, trademark Joss Whedon," executive producer Julie Plec tells EW. "If you've learned anything from the Whedonverse seasonal-structuring school like we have, then there might be some bigger and badder people coming [later]."

On "Supernatural," Roché brought an element of snarky humor to a character that might have been otherwise unlikable, turning him into a fan favorite in no time. We'll likely be swooning over this potential villain before his first episode is finished. "He showed up for a costume fitting, and I got an email from the costume designer that all of the women in the costume fitting were flushed and atwitter because he's a very charming, handsome man," Plec says.
