Vampires of Mystic Falls, beware! A new vampire hunter is coming to town, Entertainment Weekly reports.

Fringe and Supernatural alum Sebastian Roché has been cast on The Vampire Diaries as a mysterious man who appears to be hunting vampires, specifically Klaus (Joseph Morgan). "For some reason, Klaus, who shouldn't be afraid of anybody, seems to be concerned about this person," executive producer Julie Plec tells the magazine.

The yet-to-be-named recurring character was originally described in casting breakdowns as "rugged, handsome, charming and dangerous." It is unknown when exactly Roché will make his Vampire Diaries debut, but the role was originally being cast for the third episode of Season 3.

Roché recurred on Fringe and Supernatural last season and most recently guest-starred on Criminal Minds. However, he is best known to many, including Plec, for his role on General Hospital as Jerry Jacks. "He's a classically-trained theater actor, he is mysterious, he has an element of danger to him," Plec told EW. "We liked the idea of bringing an adult into our world that wasn't one of our founding families. He's just got a quality that is really exciting."

The new season of The Vampire Diaries premieres on Thursday, Sept. 15 at 8/7c on the CW.
