Todd Williams is on his way to Mystic Falls - and this may mean trouble for our favorite blood suckers.

The actor has been cast on The Vampire Diaries Season 4 as Connor, a vampire hunter who will debut on the October 18 installment of this CW drama and who is described in network notes as a "highly trained killing machine."

Williams has experience playing men on the right side of the law, having portrayed a detective on In Plain Sight and a police officer on The Chicago Code.

No word yet on exactly how he'll interact with Damon, Stefan and company. But don't expect his hunter to get along as well with his supposed prey as the show's previous hunter. (RIP, Alaric. We miss you, buddy.)

In a Season 4 press release, The CW referred to a "new villain" intent on "destroying" the bond Elena and her friends have with their hometown. It's safe to assume this outline was referring to Williams' Connor.
