Teen Wolf's Beacon Hills is teeming with supernatural villains.

'Teen Wolf' Season 5: 'No One Can Stop' Malia, Will She Kill The Desert Wolf?

The midseason premiere treated viewers to Making a Murder: The Theo Edition, but the young sociopath is hardly Scott's (Tyler Posey) only problem. Season 5B will see the True Alpha take on the chimera pack, the Dread Doctors, the Beast, and to a lesser extent, Deucalion (Gideon Emery).

It's that last one that has us concerned, however. We've already seen what the Alpha Pack leader is capable of, and "The Last Chimera" left us wondering just how he will come into play.

"Deucalion is a little different," Posey said of the calculating baddie. "You're really not sure what his motives are. His storyline mostly involves Theo, so you'll get to see two villains team up, which is really cool."

"Cool" hardly seems like the best description. We'd opt for "terrifying" or "nerve-wracking" in this case.

There is an upside, however. Perhaps the brash and inexperienced Theo (Cody Christian) will get in over his head. Deucalion could probably play that snot-nosed kid like a piano.

Despite this, Posey is quick to remind fans who the season's true big bad is.

"The main enemy is definitely the Beast," the actor explained following the events of "The Last Chimera." "The Dread Doctors and Theo are still threats, but they're more in the shadows."
