|“||"You have the entitlement and narcissism typical of your generation. In that, you are a profound success. But, your failure taught us one thing... the banality of evil. That you were and would always be an ordinary evil."
"You think I'm ordinary?"
"We believed that to resurrect the perfect killer, we had to start with the perfect evil. From you, we learned true evil only comes by corrupting something truly good."
The Dread Doctors were the main antagonists of Season 5, though their influence on the supernatural world lingered throughout Season 6 as well. They first appeared in Creatures of the Night, when they were seen admonishing Belasko, a werewolf-garuda hybrid, for failing to kill Scott McCall and take his Alpha powers. From then on, it was quickly revealed that they were experimenting on teenagers and turning them into hybrid creatures that became known as chimeras (a being made up of parts of different animals). Among those they turned into chimeras were Theo Raeken, Belasko, Tracy Stewart, Donovan Donati, Lucas, Josh Diaz, Hayden Romero, Corey, Beth, and Noah Patrick.
In addition to these hybrid creatures, the Dread Doctors also performed procedures on several true supernatural creatures as well, including shocking Scott McCall in the chest to exacerbate his wolfsbane-induced asthma attacks and weaken him, summoning a lightning bolt to channel through a lightning rod inserted into Kira Yukimura's eye to superpower her Kitsune spirit, and giving Liam Dunbar an infusion of a special type of wolfsbane in the form of a black fluid through an IV pump.
At the end of the first half of Season 5, the Dread Doctors uncovered what appeared to be a prophetic fresco painting hidden behind a tiled wall in their operating theater that depicted a hellhound fighting against the Beast of Gevaudan, which foreshadowed the battle yet to come in the second half of the season. In Damnatio Memoriae, it was revealed that the Dread Doctors did, in fact, resurrect the Beast (Sebastien Valet) by placing his spirit into the body of the first and only successful chimera, which was eventually revealed to be Mason Hewitt in The Beast of Beacon Hills. According to the Dread Doctors, Mason was their only successful chimera due to the fact that he was a truly good person, and they had learned from their experimentation on Theo Raeken that true evil can only come from corrupting something truly good.
Using vibrational frequencies, the Dread Doctors forced Mason to transform into the Beast multiple times, causing him to grow in strength and power (as well as allowing Sebastien's spirit inside of him to remember more and more of his true identity) and go on several large-scale massacres before his body morphed into the Beast without prompting and subsequently mauled the Dread Doctors to death. The Surgeon survived just long enough to reunite with the newly transformed Sebastien, revealing that The Surgeon was, in fact, Sebastien's former best friend and comrade from the 18th century, Marcel. Sebastien then continued the new life given to him by his friend until the banshee Lydia Martin managed to use her voice to force Sebastien to turn back into Mason, ending the Dread Doctors' dream of resurrecting the world's perfect killer.
Almost nothing is known about the Dread Doctors' lives before they gained the esoteric powers that allowed them to experiment on teenagers and turn them into chimeras. The only member whose early life is somewhat known is The Surgeon, who was formerly a French soldier in the Seven Years' War named Marcel who fought alongside his best friend and comrade, Sebastien Valet in North America in 1760. He was present when Sebastien transformed into the Beast of Gevaudan, the world's most ferocious and violent werewolf, by accidentally drinking rainwater from a wolf's paw print in the forest during their time serving in what is now known as Montreal, Canada. Upon their return to their hometown of Gévaudan, France some time later, Marcel helped Sebastien cover up the hundreds of victims he killed throughout his reign as the Beast, even after Marcel was caught by Sebastien's sister and Gévaudan's best huntress Marie-Jeanne Valet, who initially believed Marcel to be the Beast before ultimately realizing that he was simply covering up for her brother.
After Sebastien/the Beast was killed by Marie-Jeanne in 1767, it is assumed that Marcel decided to dedicate his life to becoming a surgeon (if he was not one already) and worshiping the supernatural, with the ultimate goal of resurrecting his dear friend Sebastien, as he believed the Beast to be the world's most perfect killer. He became known as The Surgeon, and, in his experiments, he managed to harness electromagnetic forces within a steampunk-style mask, bestowing upon himself the power to manipulate electromagnetic fields, which he used to various effects, including controlling electricity and magnetism, manipulating the memories of his test subjects, and extending his lifespan far beyond normal limits. It is assumed that he was eventually joined by two more physicians who eventually became known as The Pathologist and The Geneticist, who also gained the same powers that The Surgeon possessed. The three then began to work together to resurrect the Beast of Gevaudan.
Sometime around the World War II era, the Dread Doctors settled in Russia, where they engaged in experimenting on pregnant women and their unborn children to use science to replicate the supernatural. Whatever they accomplished while in the country was so disastrous that the Russian government covered up their experimentation by claiming their laboratory was a dangerous nuclear site with unhealthy amounts of radiation. However, this cover-up didn't convince everyone, and graffiti at the site, which read "They come. They come for all of us," suggested that the legends of the Dread Doctors have not been forgotten.
They also managed to capture a Nazi soldier in the German military who was also an Alpha Löwenmensch (a lion-wolf hybrid shapeshifter). The Doctors called this man Der Soldat, which is German for "the soldier," and they somehow utilized the healing factor in his blood (which continued to bleed through wounds caused by the Ghost Riders that wouldn't heal), mixing it with the original version of the regenerative green serum the Doctors had already created so that they could use to further improve their health and extend their lives in conjunction with their existing electromagnetic powers. They kept the soldier in a large tank of the green serum for seventy years, during which time the serum made him stronger while his blood made the serum more potent. In Season 6, it is implied that Der Soldat was a severe burn victim and that the Dread Doctors used heliox therapy to keep him breathing normally while they used his body to augment their experiments; it was then later revealed that he had actually been lashed by the Ghost Riders' whips, causing wounds that wouldn't heal due to the nine venoms coating the weapon.
At some point in the early 2000s, the Dread Doctors made their way to Beacon Hills, where they met the eight or nine-year-old Theo Raeken. It has been implied that they were attracted to him as a test subject due to his willingness to kill at such a young age, and as a result, they watched as Theo allowed his sister to die of hypothermia in the woods and decided to change their methods in their experimentation. According to Theo, the Dread Doctors lied to him and told him that his sister wanted him to have his heart in order to get him to kill her, but Stiles believed that Theo actively wanted to kill her and used the Dread Doctors' plans as justification; however, it remains unknown which version of events is the actual truth, though the traumatic hallucinations experienced by Theo during his time in the underground prison seem to imply that he might not have lied about the Dread Doctors' manipulations.
The Dread Doctors then harvested Theo's sister's heart before transplanting it into young Theo's body, which gave him genetic chimerism, a condition that was necessary in order to be turned into the Doctors' first pseudo-supernatural chimera; in Theo's case, a werewolf-werecoyote hybrid. Though Theo was not a suitable vessel for the Beast, he was the closest that the Dread Doctors came to creating a "successful" chimera until they finally achieved their ultimate goal of resurrecting the Beast of Gevaudan in the autumn of 2012. Since he survived his transformation without any difficulties, the Dread Doctors apparently allowed him to live in exchange for his help in creating more chimeras.
At some point in their lives, they crossed paths with Gabriel Valack, though the nature of their relationship remains unknown. However, Valack has held a grudge against the Doctors ever since, and he dedicated himself to finally stopping them from then on, even going so far as to write a novel, titled The Dread Doctors, to help those victims of their experiments to recover the memories that the Dread Doctors repressed of their experimental procedures in hopes of exposing them for who they are.
Throughout Teen Wolf
The Dread Doctors consisted of three members, each of whom apparently has their own role within the group which was likely based on their respective medical specialties.
The Surgeon was the first Dread Doctor and the creator of the trio, and as such was their leader. He was in charge of determining their course of action and often was the one who spoke for the group in conversation with others. He presumably became The Surgeon at some point after his best friend Sebastien Valet, the famed Beast of Gevaudan, was killed by his sister in 1767.
The Pathologist was the second male member of the Dread Doctors who acted primarily as the muscle of the group, using his enhanced strength to hold down their test subjects so that The Surgeon could perform his experiments on them.
The Geneticist was the only female Dread Doctor and seemed to work more on the materials the Doctors used in their experiments more so than doing the experiments herself. She was often seen giving the other Doctors injections of the green serum they created using Der Soldat's healing factor, which helped them maintain their health and longevity in addition to the longevity gained from their electromagnetic manipulation powers. Despite her more passive role in the trio, she was still a very talented fighter and was defeated in battle only by the Beast of Gevaudan.
The Dread Doctors revealed very little of their individual personalities, instead of working as a collective whole with a single-minded focus on resurrecting the Beast of Gevaudan. They were obsessed with the supernatural and cared about the results of their experiments; they had no tolerance for failure and did not give second chances, as evidenced by the fact that they killed their chimeras as soon as it was evident that they were rejecting their transformations. Because of this solitary focus on their ultimate goal, they regarded anything outside of it as inconsequential and would typically not waste their time on any issue that didn't contribute to their mission of resurrecting the Beast.
For this reason, they typically did not kill bystanders or witnesses unless they got into the way of their goals, and only seemed to want to harm the McCall Pack because of their interference with their experiments. However, they were willing to make deals in order to facilitate their goals, such as working with Theo Raeken, who agreed to help keep the McCall Pack distracted in exchange for the Doctors' help in turning the pack against Scott McCall so that Theo could steal his Alpha powers, become a real werewolf, and take control of the pack for himself.
Though they were not concerned with killing unless it served their agenda, they seemed to genuinely be awestruck by the Beast, regarding him as the perfect killer and doing anything in their power to bring him back, to the point where they even seemed unconcerned by the prospect of their own deaths when the Beast finally realized its true identity and fatally mauled them all.
The Dread Doctors were nearly always seen wearing their helmets and armor, which had a very steampunk style; this included bronze or brass helmets, which had rusted with verdigris as it aged, wool peacoats, brocade vests, and silk shirts with utilitarian slacks. Their color scheme was predominantly dark colors such as black, forest green, and navy blue, though The Surgeon would wear a gold and pink brocade vest with a light pink silk shirt under his jacket. The Geneticist, as the only female, wore black skirts with fishnet stockings and platform boots with numerous silver buckles, making her style more modern and trendy than her cohorts and possibly indicating that she may be the youngest of the Doctors. All three Doctors also wore robotic gloves and gauntlets over their hands to hide how scarred and aged their skin had become through their extended lives.
However, their true appearances were seen on two occasions. In Strange Frequencies, The Geneticist was briefly seen without her helmet, revealing her skin was scarred and covered with age spots, with her head nearly bald and covered with sparse patches of white hair. She also had a small hole drilled into her skull behind her ear, suggesting that she may have performed trephination on herself to further augment her abilities like Gabriel Valack. In Apotheosis, Sebastien Valet removed The Surgeon's helmet to reveal that he was actually Sebastien's former best friend Marcel; his skin was mottled, wrinkled, and scarred just like The Geneticist's due to his advanced age, with a bald head that had sparse patches of white, brittle hair; even Sebastien remarked that the Dread Doctors' form of immortality was unattractive due to the fact that they did not have eternal youth to go with it.
|Theo Raeken||Werewolf and Werecoyote traits; rare ability to full-shift into a wolf||N/A||The Last Chimera (flashbacks)|
|Theo was approached by the Dread Doctors when he was around nine or ten years old, as they were impressed with his sociopathic traits and willingness to kill at such a young age. The Doctors then turned Theo into a Chimera after giving him an organ transplant after Theo had (either directly or indirectly) killed his sister and harvested her heart. Theo was the first Chimera to survive the transformation, but was technically a failure due to the fact that he manifested traits from both a Werewolf and a Werecoyote, making him an unsuitable host for the Beast.
Theo later returned to Beacon Hills in the autumn of 2012 to take over the McCall Pack, as he intended to become a real Werewolf and Alpha by having Scott McCall killed and stealing his Alpha status before then taking control of his powerful and unique pack. After Theo's attempt to kill Scott failed, he used the Dread Doctors' Green Serum to resurrect four of the failed Chimeras-- Hayden Romero, Tracy Stewart, Josh Diaz, and Corey Bryant. He killed Josh and Tracy, stealing their powers in the process in hopes of using them to steal the Beast's powers for himself, but this plan ultimately failed as well. When he attempted to attack Scott once again, his girlfriend and packmate, the Thunder Kitsune Kira Yukimura, used her magically-empowered katana to open a sinkhole in the earth, where his deceased sister crawled out and pulled him down the hole with him.
Theo was released from his prison three months later by Liam Dunbar and Hayden Romero, who believed the powers he stole from Josh involving Electromagnetokinesis could help them catch and trap a Ghost Rider in hopes of figuring out their plans for Beacon Hills. However, shortly after his release, it became clear that he lost all of the powers he stole during his imprisonment, making his return useless in the eyes of Hayden and Liam until Theo assured him he could still be useful due to the Dread Doctors teaching him about the Ghost Riders; his value as a free man increased, even more, when it became clear that Theo still remembered Stiles Stilinski, who had been captured by the Ghost Riders and erased from everyone else's memories. Theo remained a reluctant ally and even a friend to the McCall Pack through the rest of the series.
|Belasko||Werewolf and Garuda traits, including glowing blue eyes, fangs and glowing talons; rare ability to absorb supernatural powers||The Surgeon||Pre-Creatures of the Night|
|Belasko was a genetic chimera who was turned into a scientifically-empowered Chimera by the Dread Doctors, causing him to manifest the traits of a Werewolf and a Garuda, including specially-created talons that had the ability to absorb supernatural powers. Belasko used these talons to try to take the powers of the Hellhound Jordan Parrish and the True Alpha Werewolf Scott McCall, but was unsuccessful in completely taking them both. After failing to steal Scott's powers and kill him, the Dread Doctors informed him that they did not give second chances before The Surgeon stabbed him in the chest with his sword cane, causing a flock of crows to fly out of his chest after his death. His claws were then used by Malia Tate to steal the powers of her mother, the Desert Wolf.|
|Tracy Stewart||Werewolf and Kanima traits, such as paralytic venom, reptilian tail, claws and gold reptilian eyes||The Surgeon & Theo Raeken (1st & 2nd time, respectively)||Parasomnia|
|Tracy was a genetic chimera due to an allogeneic skin graft she received on her right shoulder. As a result, she was transformed into a scientifically-created Chimera by the Dread Doctors, causing her to develop the traits of a Werewolf (fangs and claws, super strength, speed, and senses) and a Kanima (venomous claws and tail, super durability, reptilian tail and scales). Because she suffered from night terrors prior to her transformation, they became amplified by her supernatural powers, causing her to unintentionally attack and kill anyone who had tried to help her during a bout of homicidal somnambulism.
Once she began bleeding modified mercury, she was killed by The Surgeon with an overdose of the same mercury. She was later resurrected by Theo Raeken using the green serum, which resulted n her personality becoming darker and more sociopathic like Theo's. Though she immediately joined the Chimera Pack without protest, she was ultimately killed by Theo so he could steal her powers, as he believed her venom would paralyze the Beast and allow him to steal his powers as well.
|Donovan Donati||Wendigo and Lamprey traits, such as pure glowing white eyes, multiple rows of fangs, superhuman physical abilities, and round lamprey mouths on his skin||Stiles Stilinski||Condition Terminal|
|Donovan was a genetic chimera due to a skin graft he received following a car accident several years prior to Season 5. This caused him to be targeted by the Dread Doctors, who changed him into a scientifically-created Chimera. After some experimentation, the Dread Doctors tracked him to a prison transport van that was taking him to lock-up, where they drilled into his head and injected him with modified mercury. He began developing heightened senses and a silver fictitious membrane over his eyes while in the holding cell at the Beacon County Sheriff's Station, and was eventually captured there by the Dread Doctors, who took him to their operating theater.
There, they pulled out all of his human teeth so that they could be replaced by Wendigo fangs, revealing the cannibalistic species was half of his Chimera nature. He later revealed that he was also part-Lamprey after demonstrating the ability to produce round fanged mouths all over his skin. He was eventually visited by Theo Raeken, who freed him from his restraints and gave him the inspiration to get back at Sheriff Stilinski by going after the person he loves most-- his son Stiles. Unfortunately for Donovan, he was inadvertently killed by Stiles after the human teenager dropped a load of metal braces on his head in hopes of disabling him long enough to run away, causing him to accidentally be impaled through the chest by one of them.
|Lucas||Werewolf and Scorpion traits, including black eyes, scorpion stingers, and venom||The Surgeon||Condition Terminal|
|Lucas was a genetic chimera as a result of receiving a cornea transplant in his early teens. Originally a very shy, timid, and nervous person who was afraid to move too quickly with his boyfriend, Corey Bryant, his transformation into a Chimera with Werewolf and Scorpion traits by the Dread Doctors caused him to become a confident and slightly sociopathic person. He began making out with Corey extremely passionately before extending his scorpion stingers and stinging Corey, causing him to go into horrendous agony as a result of the venom in his body.
Lucas then went to Sinema that night, where he picked up Mason Hewitt and intended to do the same thing to him until the born-werewolf Brett Talbot saved him first. Lucas was neutralized in a fight with Brett, Scott, Kira, and Liam, and was nearly killed by Kira's overpowered Kitsune spirit until she was stopped by Scott. However, the Dread Doctors, who knew he was a failure, arrived and killed him anyway, stating that his condition was terminal.
|Josh Diaz||Traits of two unknown supernatural species, including purple eyes, long fangs and electro-magnetokinesis||Theo Raeken (1st & 2nd times)||Required Reading|
|Josh was a genetic chimera who was eventually transformed into a scientifically-created Chimera by the Dread Doctors. His powers were similar to that of the Dread Doctors in that he was able to absorb and manipulate electricity and magnetic energy. However, his condition began worsening from the start, causing him to go on a rampage around Beacon Hills in which he chewed on electrical wires at various places to absorb the electricity.
While on the roof of Beacon Hills Memorial Hospital, he stumbled upon the hallucinating Stiles Stilinski, who he began to attack until Theo Raeken appeared and fought him for a short time until he ultimately clawed his throat out. A week or so later, Theo resurrected him with the green serum and had him join his Chimera Pack. Josh was hesitant at first but ultimately opened up to it when Theo showed him how to get "high" from absorbing electricity. It was later revealed by Deucalion that Josh's powers were rooted in electromagnetic energy, making him one of the few people to be able to wear the Dread Doctor Mask without dying. When Josh refused to put it on to learn the identity of the Beast of Gevaudan, Theo killed him and stole his powers so he could wear the mask himself.
|Hayden Romero||Werewolf and Werejaguar traits, including gold eyes, fangs, claws and jaguar spots (formerly)||Dread Doctors||Dreamcatchers|
|Hayden was a genetic chimera after receiving a kidney transplant in her early teens, which was why the Dread Doctors chose her to become one of their scientifically-created Chimeras. It was first hinted that she was a Chimera in Dreamcatchers when claw gashes to her wrist healed in minutes, but it wasn't until Required Reading when she displayed superhuman hearing and eyes that reflected light, that it was officially confirmed that she was a Chimera. The McCall Pack, including her love interest Liam Dunbar, attempted to create a fortress at the high school to protect her from the Dread Doctors, but they were able to easily incapacitate the pack with hallucinations before capturing both Hayden and Liam.
Their experimentation on Hayden revealed that her condition was worsening, and though they were freed by Theo and recovered from their torture, Hayden was still deemed a failure and given an overdose of modified mercury by the Dread Doctors, which eventually caused her to die. However, she was resurrected by Theo Raeken, causing her personality to become somewhat darker as she reluctantly joined his Chimera Pack. However, after Liam helped her reconnect with her humanity, she switched allegiance back to the McCall Pack. She was critically injured in a battle with Sebastien Valet, and once Alan Deaton informed the pack that her injuries may not heal in time to save her life, Scott McCall gave her the Bite, turning her from a pseudo-supernatural hybrid into a truly supernatural Werewolf.
|Corey Bryant||Traits of two unknown supernatural species, including super strength, accelerated healing, and adaptive camouflage||The Surgeon||Strange Frequencies|
|Corey was a genetic chimera who was eventually turned into a scientifically-created Chimera by the Dread Doctors. It was first hinted that he was a Chimera when he miraculously survived Lucas' scorpion sting in Condition Terminal (albeit with assistance from Scott McCall's pain absorption), but it was not officially revealed until Strange Frequencies, when his ability to heal and not get drunk caused him to realize that he had been transformed as well. Like nearly all of the other Chimeras, he began showing signs of being a failure when he began projectile-vomiting modified mercury and black blood, and though he quickly manifested his ability to blend into his surroundings like a chameleon, he was still tracked down and killed by the Dread Doctors.
Several days later, he was resurrected by Theo Raeken using the green serum and reluctantly joined his Chimera Pack. Corey fought alongside Theo and the other Chimeras, even sustaining full-body burns from the Hellhound Jordan Parrish's pyrokinesis, but his new boyfriend Mason Hewitt helped him reconnect with his humanity and turn his allegiance from the Chimeras to the McCall Pack. Corey is currently the only living Chimera since Theo's current status is unknown and the other Chimeras were either killed, turned into supernatural shapeshifters, or lost their powers.
|Female Chimera||Traits of two unknown supernatural species, including long needle-like claws||Kira||Strange Frequencies|
|Very little is known about this Chimera, aside from the fact that she appeared to be in the process of rejecting her transformation, judging by the black blood and modified mercury she was secreting after her death, and the fact that she had long, black, needle-like claws. Her body was found lying face-up on the kitchen table at the McCall House by Melissa McCall, and he had Kira's katana skewered through her chest, leading everyone to believe that Kira killed her while her inner Kitsune spirit was in control.|
|Zach||Traits of two unknown supernatural species, including wings on his back||Dread Doctors||Ouroboros|
|Zach was a genetic-chimera-turned-scientifically-created-Chimera who was being held in the Dread Doctors' holding cell when Hayden and Liam were locked up there. He asked the two if they would look at his back and lifted his shirt to reveal the two stubs of wings between his shoulder blades that had been removed recently by the Dread Doctors. He explained what he knew about the characteristics of a Chimera failure before he got a nosebleed that dripped modified mercury and was promptly taken away and killed by the Dread Doctors in their operating theater.|
|Beth||Traits of two unknown supernatural species, including super strength||The Pathologist||Lies of Omission|
|Beth was a classmate of Malia Tate and a genetic chimera who was eventually transformed into a scientifically-created Chimera by the Dread Doctors. While in class, she was anxiously biting her nails as she tried to research information about her condition, but when one of her fingernails fell off and began bleeding black blood and modified mercury, she began to panic and ran out of the room. When Malia followed her outside, stating that she shouldn't be alone, Beth insisted that Malia knew nothing of her condition and shoved her forcefully against the row of lockers with her super strength. Beth was then cornered by the Dread Doctors and had her neck snapped by The Pathologist before Malia could even react.|
|Noah Patrick||Traits of a Berserker and an unknown supernatural species, including super strength, bone spikes, and thirst for bone marrow||Dread Doctors||Status Asthmaticus|
|Noah was a genetic-chimera-turned-scientific-Chimera created by the Dread Doctors who manifested the traits of a Berserker, such as super strength and the ability to extend and retract bone claws from his wrists and hands. He also developed a taste for human bone marrow, suggesting that the other creature who made up his Chimera nature also was known for feeding on red bone marrow. Noah demonstrated signs of being a Chimera failure when he lost control and attacked Malia Tate and Sheriff Stilinski, the latter of whom became poisoned by a piece of his bone spike left in his abdomen. Despite the McCall Pack's attempts to save him, he was presumably killed by the Dread Doctors.|
|Mason Hewitt||Host for the Beast of Gevaudan||N/A||The Beast of Beacon Hills|
|Mason was a rare genetic chimera, in that he had two sets of DNA due to him absorbing his twin in the womb, a condition called fetal resorption syndrome. As a result of this in addition to his kind and compassionate nature, the Dread Doctors chose him to be one of their scientifically-created Chimeras. However, unlike the others, Mason was the only successful Chimera, as, according to The Surgeon, in order to create the perfect evil, you must corrupt something perfectly good. Mason then unknowingly became the host of the spirit of Sebastien Valet, better known as the Beast of Gevaudan, history's most feared and powerful werewolf.
After the Dread Doctors used frequencies to force Mason to shift, making him gradually stronger and making Sebastien's spirit gradually more aware of who he truly was, Mason went on several killing sprees while in a blackout that resulted in the deaths of over two dozen people total. In The Beast of Beacon Hills, Mason successfully transformed without prompting through frequencies, causing him to shapeshift into the human body of Sebastien Valet, and it wasn't until Lydia Martin used her Banshee voice to turn him back that he was able to exorcise the Beast. Since he gained his powers from Sebastien's spirit, which was once again killed, Mason no longer has any Chimera powers.
Powers and Abilities
- Telluric Currents: The Dread Doctors, due to their powers of electromagnetic manipulation, were unable to enter buildings that were situated on top of powerful convergences of telluric currents, such as the convergence that runs under Eichen House. As a result, they were forced to overpower Kira Yukimura, a Thunder Kitsune, with a lightning bolt before luring her to Eichen House so that her presence and involuntary production of foxfire could temporarily disable the currents' effects on them and allow them to enter.
- Ultrasonic Emitters: Because the Dread Doctors' powers were based on certain electromagnetic frequencies, they could be disabled by conflicting frequencies, such as the ones used by the Argent family in their ultrasonic emitters. This was proven when Gerard Argent used one of their emitters to prevent the Doctors from using their powers against him.
- Dread Doctor Masks: These masks harnessed electromagnetic forces and allowed them to gain their powers. One specific mask, created by The Surgeon, fell into the hands of Gabriel Valack, and it could allow the wearer the ability to see things no one else could see, though it was nearly always fatal to anyone who did not already possess electro-magnetokinesis like the Doctors did.
- Modified Mercury: This substance was created by the Dread Doctors, allowing them to inject it into humans with genetic chimerism to turn them into pseudo-supernatural chimeras. The chimera would then be buried in the ground as part of an incubation process before being given one last injection that would be the last step in starting their transformation.
- Green Serum: The Dread Doctors created a serum using the healing factor of an Alpha Löwenmensch known as Der Soldat that possessed miraculous healing properties. It could heal wounds, improve health, and extend the lifespans of those who were given regular injections of it, which the Dread Doctors used to stay alive for over two centuries. Its most impressive quality is that it can even resurrect the dead when injected into a corpse; it was used to resurrect Hayden Romero, Tracy Stewart, Josh Diaz, and Corey Bryant, all of whom had been dead anywhere from several hours to several weeks, though they did experience a darkening of their personalities as a result. The serum also allowed them to successfully transition into chimeras, despite the fact that they had died because their bodies rejected the transformation.
- Argent Sword Cane: After the death of the Beast of Gevaudan at the hands of Marie-Jeanne Valet, Marcel stole the special pike she used to kill her brother, which contained wolfsbane and mountain ash in the steel and had been forged with her blood under the light of a full moon, and reforged it into a sword cane, which he kept for nearly 250 years in case he needed it to kill the Beast in the future.
- Frequency Goggles: The Dread Doctors created a pair of goggles that had spikes, which would impale the soft tissue around the eye socket and create a bond with the wearer that would allow them to hone in on a specific frequency in order to locate a person. The Dread Doctors themselves used these goggles to keep track of all of their Chimeras, as they were each given a specific frequency during their transformation into Chimeras, and Theo Raeken allowed Malia Tate to borrow them so that she could use them to track down her mother, the Desert Wolf, a werecoyote who, like all supernaturals, had her own unique frequency as well.
- The Surgeon, who was the creator of the Dread Doctor group, was over 250 years old at the time of his death, though it is unknown how old the other members were and when they officially joined him.
- If the stories in The Dread Doctors novel by Gabriel Valack are true, the Doctors possibly created numerous other Chimeras in other cities, including a town in the northeastern region of the United States known as New England.
