Teen Wolf's Dread Doctors are back like a bad habit.

'Teen Wolf' Season 5: This Cast Member Is All For Stydia, Here's Why Fans Should 'Stay Tuned'

The Beast beheaded, disemboweled, and generally turned its creators to piles of leader and blood during "The Beast of Beacon Hills," but another steam punk scientists will rear its masked head in the season 5B finale, "Apotheosis."

Check out the new doc in the promo below at 9 seconds and 13 seconds.

'Teen Wolf' Season 5: Will Mason Survive? Khylin Rhambo Teases His Turn As The Beast

Is it Theo (Cody Christian)? Unlike the Eichen House nurse, the Chimera pseudo-Alpha has found a way to survive the mask (thanks a lot, Deucalion). The teenage sociopath isn't quite the brand of evil the Doctors were looking for, but he just might be able to follow in their footsteps. Although, after their rather harsh critique of his character in "The Beast of Beacon Hills," heaven only knows why he'd want to continue their work.

His lust for power is insatiable, and if he can't steal the Beast's mojo, perhaps dabbling in the Doc's werewolf-powered immortality will help him achieve his nefarious goals.

Find out who will win the final battle against the Beast when Teen Wolf airs Tuesdays at 9 p.m. ET on MTV.
