Someone is cracking skulls at Beacon Hills High, and it isn’t the Ghost Riders. As nefarious as “Teen Wolf”’s new villains are, Scott and co. will have to divide their interests when an old evil finds its way into their hallowed halls. The students of BHHS have a shiny new distraction – this time in the form of a hot physics teacher by the name of Mr. Douglas. Pete Ploszek’s character might have the teenage girls swooning, but, behind that gorgeous visage, he is hiding a bloody secret.

Jeff Davis’ MTV series loves its mysteries, but the identity of the Dread Doctors’ little lab experiment isn’t one of them.

Douglas whips out his fangs in the latest season 6 promo, WWII flashing in the background. With that reveal floating around in the ether, Davis dropped a few teasers regarding the nazi werewolf.

“We have a joke that Beacon Hills High School should be a lot better at background checking,” Davis told TVLine. “If they looked into his background, it would go all the way back World War II. … You see him in a flashback in the trailer, bearing his fangs.”

Unfortunately for Beacon Hills’ teenage supernatural denizens, this is one werewolf whose bite is way worse than his bark. Unassuming in the daytime, Douglas can bite straight through a man’s skull in the darkness. Scott’s (Tyler Posey) pack is no longer focused on merely passing senior year – they’ll be lucky if they survive to graduation day.

What’s next for ‘Teen Wolf’?

Currently, the Ghost Riders are on a tear, wiping innocents from existence with impunity. Now that Stiles (Dylan O’Brien) is in the wind, his friends will have to dig deep to resurrect his memory. As Lydia (Holland Roden), Malia (Shelley Hennig), and Scott tend to that aspect of the investigation, the younger generation of werewolves and chimeras will have their own issues to deal with.

Check out the summary for Nov. 22’s “Superposition,” a clear throwback to the premiere’s Schrodinger’s cat reference:

“While Scott, Lydia and Malia search for lost memories of a missing friend, Corey discovers a connection between his abilities and the Wild Hunt,” MTV teased.
