The Dread Doctors are the primary antagonists for Season 5 of MTV's Teen Wolf.


Dr. Valack says they’re not entirely human anymore. He says they were scientists who worshiped the supernatural.

Marcel, a bar owner and soldier in the French and Indian War, was a loyal friend to Sebastien Valet and covered his crimes as The Beast of Gevaudan. After his death, Marcel began to practice the farthest edges of pseudoscience and harnessed electromagnetic forces in order to bring back his friend. Along with two others, they used these forces to prolong their lives, give them power, and, most importantly, make people forget about them.

According to Dr. Valack, the doctors came to Beacon Hills prior to the McCall Pack's encounter and many people had died before leaving and only returned when the group reactivated the Nemeton. (A Novel Approach)

How they've been able to prolong their lives is from a Nazi werewolf, Garrett Douglas. Keeping him in a tube with green fluid, they inject themselves with it when necessary. (The Beast of Beacon Hills)

Their primary goal was create the perfect killing machine. They nearly succeeded with Theo Raeken who they described as "perfect evil," however, they discovered to create real evil was to "corrupt something good." Harnessing the power of La Bête du Gévaudan, they resurrect Sebastien Valet through Mason Hewitt.

Once the beast remembered who it was, it killed the doctors while they reveled in their success.

The Book

Teen Wolf Season 5 Episode 4 Condition Terminal Dread Doctors Book

A novel, first seen in Tracy Stewart's room in Episode 504, is titled "The Dread Doctors" by T.R. McCammon. The book's tagline is “A terrifying tale of science fiction and horror.”

The book was actually written by Dr. Gabriel Valack. He says it details an earlier visit from the Dread Doctors.

The back cover reads:

“In a small New England town, teenagers are taken in the night and buried alive. Days later they emerge transformed wreaking havoc and spreading terror, commanded by an ancient order of parascientists known only as the Dread Doctors.”

Valack says he wrote the book to stimulate readers' brains and allow them to remember any interaction they might have had with the Dread Doctors.

Excerpts of the novel are shown on screen. Two pages are transcribed on the Required Reading recap page and two partial pages can be seen on Ouroboros recap page.

The Cane

Owned by the Surgeon, he uses it as a weapon to killed failed experiments or defend himself. It is revealed to be the pike that Marie-Jeanne Valet used to kill her brother. It was forged steel mixed with Wolfsbane, Mountain Ash and Marie's blood under the light of a full moon. When it is used on Sebastien again, it disappears along with him.

The Goggles

In The Sword and the Spirit, Theo lets Malia use these spiked goggles to find her mother. He explains that all supernatural creatures vibrate at certain frequencies that differ one from another. For them to work, one places the goggles over their eyes, flip a switch, and the spikes shoot out and embed themselves in the soft tissue just below the eyes. With enough focus, Malia was able to pin point the location of The Desert Wolf.

The Mask

These Masks are imbued with electromagnetic properties that can potentially kill anyone who puts it on. It came into Dr. Valack's for awhile until Theo steals it to find the identity of The Beast.


Dr. Deaton explains that, while the Doctors' experiments may appear to be familiar creatures, they are not supernatural as evidenced by their ability to cross Mountain Ash barriers. The old rules and restrictions do not apply to the subjects of these experiments.

The Doctors created hybrids by combining parts, most seem to have some werewolf traits mixed with more exotic species, to form a chimera. Theo says they are "cheap knockoffs" of the supernatural creatures they resemble.

They would bury their victims in the ground for incubation before they emerged with no apparent memory of these events, then they were sought out by the doctors when they were "Awakening" to finish their construction with mercury injections. (Parasomnia, Dreamcatchers)

If an experiment is emitting black goo, the doctors consider their condition as "worsening" and will either salvage it or kill it. If mercury begins to bleed from their orifices, the experiment's condition is "terminal" and is deemed a failure before being terminated otherwise it will suffer a slow and painful death. (Ouroboros, Lies of Omission, Status Asthmaticus)

Sheriff Stilinski and Melissa McCall have figured out that several of the chimera they know about had skin or other tissue transplants at the hospital in the past. This suggests they were all genetically chimera before the Dread Doctors.

The Doctors performed some sort of procedure on Kira during the events of Creatures of the Night that amplified her powers to uncontrollable proportions.

They pumped black goo into Liam when he was briefly captured. According to Theo, this was a wolfsbane solution designed to suppress his abilities and make it impossible to find their lair again as he attempted the same procedure on Deucalion.
