Roche will appear in a recurring role as “a very mysterious man who appears to be hunting vampires, most specifically Klaus,” reports EW.com.
Not to be confused with new addition Bill (played by Heroes‘ Jack Coleman), who comes to town to point out the Council’s failings, Roche’s character will be a source of concern for the powerful Klaus.
“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,” Plec tells EW.com. “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].”
Roche’s Supernatural character, Balthazar, met a bloody end at the hands of Castiel last season.
Season 3 of The Vampire Diaries premieres Sept. 15.
