“ Theo: "You're really gonna kill him? I mean, I don't care if you do... But, have you thought this through? Any idea where you're gonna dump the body? ...But no one saw you grab him, did they? 'Cause that could be a problem."
Liam: "I don't care."
Theo: "I don't care, either. But, at least let me help! I'm the one with experience here. If we kill him, we have to find the witnesses and kill them, too... Which means we're gonna need shovels, some plastic bags, maybe a chainsaw..."
Liam: "You made your point."
Theo: "And you didn't kill him-- that's progress!" 		”
— Theo Raeken talking Liam Dunbar out of killing Gabe in Werewolves of London


Theodore "Theo" Karl Raeken is a supporting character on Teen Wolf who made his first appearance in Season 5A. He was the first Chimera created by the Dread Doctors who managed to successfully complete his transformation without rejection, though he was not considered a true success. He went to school with Scott McCall and Stiles Stilinski up until the fourth grade, which was when his family left Beacon Hills, a year or two after the death of Theo's sister, Tara.

Theo returned to Beacon Hills for his senior year in the autumn of 2012 and wasted no time seeking out the McCall Pack in hopes of joining them. He posed as a recently-bitten Werewolf whose Alpha died before his first full moon, leaving him as an Omega; in reality, Theo was trying to get close to the members of the pack, as he planned turning them against their Alpha Scott McCall and eventually killing him in order to steal his powers and become Alpha himself, coveting the unique combination of supernatural creatures that made up the pack.

Unfortunately, Theo's plan, while perfectly executed for the majority of the half-season, was foiled when Mason Hewitt arrived and stopped Liam Dunbar from killing Scott at the last moment (since Theo, knowing only a Beta of a True Alpha's own making could steal their power, needed Liam to become an Alpha first in order to steal the power for himself). As a consolation prize, Theo used the Dread Doctors' green serum in order to resurrect four of the previously killed "failed" Chimeras whose bodies were left at the Nemeton, creating his own Chimera Pack in which he was the self-appointed "Alpha" (despite the fact that he was neither a real Alpha nor a real Werewolf).

Throughout Season 5B, Theo continued his quest for more power with the help of his packmates, only this time, he focused his sights on stealing the powers and lycanthropy of the Beast of Gevaudan, who had recently been resurrected by the Dread Doctors. To do this, he pursued several different leads that he thought could help him achieve his goal, including obtaining Belasko's talons, capturing Deucalion (the only surviving expert in stealing powers from other creatures), and attempting to capture Lydia Martin, knowing that her Banshee connection with Jordan Parrish, the Hellhound prophesied to battle the Beast, would lure both Parrish and the Beast to him. He even killed two of his "Betas," Tracy Stewart and Josh Diaz, in order to steal their powers of Kanima venom production and electromagnetokinesis, respectively.

However, Theo's plans once again failed when the Beast proved immune to his venom. When he tried to retaliate against the McCall Pack for thwarting his plans (due in part to Deucalion, who was secretly working with Scott and had allowed himself to be captured) Kira Yukimura, with the help of the Skinwalkers, summoned Theo's deceased sister to drag Theo through a sinkhole and trap him underground. Theo's remained imprisoned beneath the underground tunnels of Beacon Hills until he was set free by Liam and Hayden in Season 6A's Ghosted.

After Theo's release, he maintained his usual survivalist personality, but slowly began to change as a result of the McCall Pack's influence, especially once Liam had destroyed Kira's katana so he couldn't be sent back to his underground prison. By the end of the first half of the sixth season, Theo demonstrated genuine concern for people other than himself when he helped prevent Liam from being captured by the Ghost Riders and fought alongside Scott, Malia Tate, and Peter Hale (a former "bad guy" who was also on a redemption arc of his own) against Garrett Douglas and the Ghost Riders as well.

As of Season 6B's Raw Talent Theo is currently homeless, leaving him forced to live in his truck. When it became clear that the Anuk-ite was wreaking havoc on Beacon Hills, he became a reluctant ally of the McCall Pack, helping them defend themselves against the fear-inducing shapeshifter and the army of Hunters that formed partly due to this fear. Despite his initial feuding with the pack, he eventually proved himself as an ally who could be trusted to help them, leading Scott (who had plenty of reason to distrust him due to Theo killing him) to even refer to him as one of the town's protectors.

Theo is a member of the Raeken Family and was the self-declared "Alpha" of the Chimera Pack before eventually becoming a trusted ally of the McCall Pack.

Throughout Teen Wolf[]

In Creatures of the Night, Theo returned to Beacon Hills with his so-called parents, where he first met Kira Yukimura during the traffic jam on Route 115 when they were both trying to get cell phone reception. He then saw Scott McCall ride up on his motorbike to pick up Kira and take her back to the high school for Senior Scribe night. At the high school, Scott and Kira were attacked by a Werewolf-Garuda Chimera named Belasko, who wanted to steal Scott's power for his own, and Theo, knowing that Scott being killed by Belasko would ruin his plans, intervened in order to help them get the upper-hand against him.


Afterward, Scott and Kira, along with Stiles Stilinski, Malia Tate, and Liam Dunbar, who had showed up when they heard their packmate and Alpha were in trouble, approached Theo, who realized Scott and Stiles didn't recognize him and explained that he had returned to Beacon Hills with his parents because he had heard about Scott's ascension to True Alpha and wanted to join Scott's pack. Though Stiles was immediately skeptical of Theo's story and concerned about the coincidence in him showing up right after they were attacked by a rabid Werewolf, Scott seemed open to giving Theo the benefit of the doubt.


In Parasomnia, Stiles, who was still suspicious of Theo's motives and the fact that he showed up just when the pack suffered their first attack in six months, insisted that he and Scott talk to Theo to learn more about what drew him back to Beacon Hills. Theo claimed that he was bitten by an Alpha against his will one day when he was skateboarding in a neighbor's empty swimming pool, but that by his first full moon, the Alpha had been killed by a pair of twins, implying that it was Ethan and Aiden's former Alpha who had given him the Bite and who then died when the twins killed him and the rest of the pack prior to joining the Alpha Pack.


That night, knowing that Stiles and Liam were following him, Theo went to the Beacon Hills Preserve with a bouquet of lilies, dropping them in the creek where his sister died as a remembrance ritual to maintain his cover of innocence. He then caught the two and demanded to know what they were doing, forcing Stiles to admit that he was suspicious of Theo's motives because he had figured out that Theo's father's signatures didn't match those from several years ago. Theo acted as though Stiles was just being overly paranoid and insisted that he only wanted what they had, which was friends and packmates who would look out for him and would allow him to look out for them all as well. Theo then reiterated that he believed he was meant to be in the McCall Pack.


Once they left, Theo revealed that he could full-shift into a dark brown wolf when he followed Liam back to the high school and chased after Liam and Mason until Liam Werewolf-roared him away, revealing his Werewolf identity to Mason in the process. At the end of the episode, Theo returned home to his so-called parents, where he berated his "father" for screwing up Jonathan Raeken's signature, insisting that everything had to be perfect to ensure that he wasn't caught in his plans. He then smashed his "father's" hand with a hammer, as he believed that a serious hand injury would be a reasonable explanation for why his signatures would have changed.


In Dreamcatchers, Theo was seen observing the pack from the shadows at the crime scene where the Werewolf-Kanima Chimera named Tracy Stewart had both attacked and killed her father as well as seriously injured his driver. At the end of the episode, he showed up at the Beacon Hills Animal Clinic, where he found Alan Deaton, Scott, and Stiles recovering from being paralyzed by Tracy's [[|Kanima Venom|Kanima venom]] and insisted that they let him help, even if they weren't ready to accept him into the pack yet. Though Stiles continued to be suspicious of him, Scott knew they needed all the assistance they could get and allowed Theo to join the three of them in traveling to the Beacon County Sheriff's Station where Tracy had gone to attack Natalie Martin.


In Condition Terminal, Theo arrived at the Sheriff's station with Scott, Stiles, and Deaton, where they found Lydia Martin bleeding out on the floor in Kira Yukimura's arms after she had been attacked by Tracy. Theo wasted no time taking off his belt and using it as a tourniquet to slow Lydia's bleeding before they could help her get to the hospital. Theo waited with the rest of the McCall Pack for news about Lydia's condition, and Melissa McCall thanked him for his quick thinking with the tourniquet, which she stated likely saved her life.


The next day, it was revealed that Theo was working hand-in-glove with the Dread Doctors when he went to talk to Donovan Donati, one of the Doctors' newest Chimeras who was part-Wendigo, part-Lamprey. He mocked Donovan for the results of the psychological evaluations he took as part of his application to become a Sheriff's deputy before stating that if he wanted to get back at Sheriff Stilinski for what happened to his father, he needed to cause emotional pain rather than physical pain; to this end, Theo suggested he go after who Sheriff loves the most (his son Stiles), and released him from his restraints in order to do just that.


In A Novel Approach, unbeknownst to anyone, Theo followed Donovan to the high school and secretly watched as Stiles was forced to kill Donovan in self-defense, a result that he likely planned on in order to manipulate Stiles into trusting him, since Donovan used Theo's library key-card to gain access to where Stiles was hiding from him. The next day, Theo met up with Scott to discuss their current Chimera problem. Scott showed Theo the copy of The Dread Doctors novel that Malia Tate found in Tracy Stewart's bedroom, and Theo subtly hinted that they should talk to the author, who was listed as J.R. McCammon but who, in reality, was Gabriel Valack, a prisoner at Eichen House with a third eye that granted him Extrasensory Perception.


Once Scott had made plans for himself, Stiles, Kira, and Lydia to go to Eichen to talk to Valack, Theo reported back to the Dread Doctors to inform them that they had found the book and were going to see the author, which the Dread Doctors seemingly orchestrated in order to use Kira's overpowered Kitsune spirit to disable the telluric currents that prevented them from entering. That afternoon, Theo went to the high school's library, where he found Malia reading a copy of The Dread Doctors novel and joined her at her table. He began subtly flirting with her and eventually offered to help her practice her driving after seeing her disastrous driver's education lesson several days prior. Malia declined at first, but ultimately decided to take him up on the offer when she realized she had missed the last bus that could take her home.


While they were driving, Theo gave Malia tips on how to hold the steering wheel and teased her about her slow speed. However, the effects of the book kicked in moments later, causing Malia to have a flashback-hallucination about the night of the car accident that led to the death of her adoptive mother and sister, where she learned that it was not her first Werecoyote transformation that caused the crash-- in reality, her biological mother Corinne, otherwise known as the Desert Wolf, shot at the car.


It was then the stress of the gunshots and the car crash that occurred after Evelyn accidentally drove into a tree to evade the shots that led to Malia transforming for the first time during the full moon, which subsequently caused Malia to attack and kill her adoptive mother and sister. Malia was zoned out during this flashback and began driving upwards of 70mph, and Theo became so concerned that she would crash the car that he forced her to stop the truck. She then ran out of the vehicle and collapsed on her hands and knees in the middle of the road, nearly getting killed by oncoming traffic before Theo tackled her out of the way just in the nick of time. She then breathlessly informed him that it was the Desert Wolf who caused the crash, much to Theo's confusion.


In Required Reading, Scott met up with Theo at school, where the former instructed the latter to keep an eye out for any of their fellow students acting strange or weird, since they were still looking for around eight Chimeras based on the number of incubation holes they found on the lacrosse field. Theo chuckled and remarked that most teenagers are generally pretty weird before asking about the book, leading Scott to invite him to join the pack at his house that night to read the book together in hopes of triggering any memories of experimentation that the Dread Doctors may have performed on them and repressed with their powers.


However, since Theo had his full memories due to being in league with the Dread Doctors, he merely pretended to read the book while observing the pack and learning more about the individual members as they all read their own copies. He overheard Stiles lying to Malia about how he injured his shoulder, which he mentally filed away for later use. He then waited until everyone was asleep before going upstairs, where he found Kira asleep in Scott's bed, where she was tossing and turning and muttering "Watashi wa shi no shisha da" in her sleep (Japanese: "I am the Messenger of Death"). Intrigued, Theo recorded her words in an audio file on his phone.


The next day, Malia confronted him in the weight room at school and demanded to know why he didn't tell Scott about what she said about the Desert Wolf. Theo played it cool and replied that he didn't say anything because he didn't think Malia wanted him to, which she reluctantly confirmed. Meanwhile, he continued to try to flirt with her by taking off his shirt to show off his muscles. She stopped him from doing weights by pinning his arms down, revealing that she was stronger than him, before asking him what his motives were, and Theo simply insisted he wanted into the pack (which Malia reminded him was not something she herself could grant him) and assured her that if she wanted to tell Scott what she learned, that was fine, but if she had something else in mind, he was okay with that as well.


That night, Stiles, in the midst of his own repressed memory from reading The Dread Doctors novel (which manifested as a flashback-hallucination of his mother, in the throes of frontotemporal dementia, ranting about how young Stiles was trying to kill her) wandered onto the roof of Beacon Hills Memorial Hospital, where he was immediately attacked by the recently-turned Chimera Josh Diaz, who had gone up there to absorb electricity from the backup generator. Josh tackled Stiles and was about to maul him with his claws when Theo, in his Werewolf form, appeared and began to fight Josh to save Stiles, which ultimately ended when Theo ripped out Josh's throat. Stiles was horrified by the sight and was eager to go to the pack to inform them that he was right about Theo, but Theo pleaded with him not to tell Scott. When Stiles asked him why he shouldn't, Theo replied, "Because I didn't say anything about Donovan."


In Strange Frequencies, Stiles and Theo continued their conversation on the roof of the hospital, where Theo claimed that he had witnessed Stiles accidentally killing Donovan at the high school after Malia, who was unable to get a hold of him, texted him out of concern for Stiles' safety. After some arguing, Stiles ultimately decided to stay quiet about Theo's hand in Josh's death and helped him smuggle the body out of the hospital and into the animal clinic. Once there, they called Scott and lied about how they found him, claiming that it was actually The Surgeon who killed Josh with his sword, a lie that Scott believed without question. Theo then offered to stay overnight with the body so that they could possibly figure out who kept stealing the bodies of all of the dead Chimeras, an offer that Scott appreciatively accepted.


The next morning, The Surgeon showed up at the clinic, where Theo updated him on the recent developments. When Theo brought up the fact that the Doctors must want to know who was stealing the bodies as much as anyone, The Surgeon simply stated that they found it inconsequential, leading Theo to realize that they already knew who the body thief really was. Theo angrily reminded them that they were supposed to be keeping him in the loop on everything, but The Surgeon once again declared the topic to be of little importance. Before they could discuss it further, Stiles arrived and pointed out that the body thief was likely not going to come if they thought that they were being watched, so they set up a camera connected to a smart watch in the animal clinic before sitting out in Stiles' Jeep in the parking lot.


While there, Theo asked Stiles why he decided to stick around, and Stiles made it clear that he still didn't trust Theo. The topic of discussion then moved to justifiable homicide, and the fact that both Theo and Stiles killed Josh and Donovan, respectively, in order to save their own lives. He flashed his gold eyes at Stiles and reminded him that if he had killed an innocent person, they would have turned blue. Theo then brought up his sister, stating that Stiles reminded him of her because she was a "smart-ass" as well, and claimed that he wanted to look out for Stiles just like he should have done for her.


In flashback, it is revealed that Theo allowed his sister to die of hypothermia while she pleaded for him to help her. Near the end of the episode, Theo caught the scent of something burning and looked out the window just before a flaming fist appeared and hit him in the face, knocking him out temporarily. It was then revealed that Jordan Parrish, in Hellhound-mode, had arrived to take Josh's body, and he flipped over the Jeep, knocking Stiles out as well so he could take the body without Theo or Stiles interfering.


In Ouroboros, upon learning that Liam and Hayden had been captured by the Dread Doctors, Theo went straight to the McCall House, where the pack was working hard to figure out where Hayden and Liam were so they could be rescued. When Scott and Malia returned to the house, Theo wasted no time asking Scott if he was okay, but Scott ignored him in favor of going upstairs, where Mason and Lydia were helping Corey read The Dread Doctors novel in hopes of triggering repressed memories that could help them locate their captured friends. When Scott stated that this was a waste of time and quickly jammed his claws into the back of Corey's neck to read his thoughts for himself, Theo ran upstairs with Stiles and Malia and watched curiously before asking Stiles what he was doing.


After Scott finally saw Corey's memories of being taken to what appeared to an operating theater in the tunnels under the water treatment plant, he suggested that Theo come with him and Malia to check it out. However, Theo, who, as an ally to the Dread Doctors, already knew where Hayden and Liam were, instead elected to stay behind to help Stiles and Lydia with Corey, leading Mason to go in Theo's place. Once they left, Theo watched as Lydia cleaned up the back of Corey's neck with a washcloth and feigned surprise when Corey's wounds from Scott's memory-reading ritual had completely healed, confirming that Corey, too, was a Chimera.


When Corey, angry and frustrated by his treatment, attempted to leave, Theo insisted that he stay, claiming that since Lydia was a Banshee who could predict someone's death, she knew better than anyone that him leaving their protection would be a bad idea, which Lydia halfheartedly confirmed. Theo then demanded that Corey think hard about his dealings with the Dread Doctors to help them find their friends, as he knew he needed to save Hayden and Liam to prove his worth to the pack but also needed an excuse for how he knew where the two were being held by the Doctors. Corey, after some reflection, finally recalled being taken to an abandoned house with a large hole in the wall after his experimentation in the operating theater, and when Theo pointed out that Jordan Parrish had mentioned being attacked by Belasko at an abandoned house, Lydia confirmed it was the same one.


Theo then rushed to the house and ran into the basement where Hayden and Liam were locked in a cell with an electrified fence around them. When Liam asked him if he could get help, Theo informed them that he was the help to make them more grateful for his rescue before fighting through the electricity and breaking the gate open, helping the two escape. While Theo was driving them back to the McCall House, he watched as Hayden and Liam talked in the backseat. Hayden grimly informed Liam that she wasn't healing and that she was in bad pain everywhere, but when she asked him if this meant she was a failure, Liam, at a loss for words, simply kissed her. Theo smirked smugly when he saw that Liam was able to use the kiss to absorb Hayden's pain, allowing her to start to heal. When Scott, Malia, and Mason returned to the McCall House, they were shocked and relieved to find Hayden and Liam sleeping on the couch, and the three each hugged Theo in turn, all of them grateful that he was able to save them when they couldn't.


In Lies of Omission, Theo went to the operating theater in an attempt to convince the Dread Doctors to keep Hayden alive for a little longer, as she was apparently instrumental in his plans to become an Alpha and steal the McCall Pack from Scott. The Dread Doctors were not amused by Theo's demands, but ultimately agreed to give him two days (until the perigee syzygy, or supermoon) before they deal with Hayden.


He later went to the Beacon Hills Animal Clinic, where Scott admitted the issues he was dealing with, including but not limited to the return of his asthma, the fact that it had been almost a full week since they had discovered new Chimeras, the increasingly distant behavior between himself and the other members of the pack, their inability to come up with a plan to deal with the Doctors, the fact that they're forced to lie to Jordan Parrish and Sheriff Stilinski about Parrish being the one stealing the bodies of the failed Chimeras, and the fact that neither Hayden nor Corey seem to want anything to do with them.


When Scott confessed that he didn't know how he was supposed to save everyone if he couldn't even breathe, Theo replied that it sounded like he was apologizing, and Scott insisted that he was sorry that he was looking for a good Alpha and found him instead. Despite this, Theo claimed to still be with Scott and the others, for better or for worse, and when Scott reminded him that things always do get worse in Beacon Hills, Theo cryptically assured him that he was counting on it, though Scott was too preoccupied with his own problems to realize how sinister his words sounded.


That afternoon, Stiles returned from exploring the Beacon Hills Preserve with Lydia in search of the Nemeton to warn Theo that Parrish and Lydia were close to finding the bodies of the dead Chimeras, which meant that they were also close to learning that Donovan and Josh had been killed him them. This clearly pleased Theo, since it meant that Stiles was starting to trust him as well, and, as part of Theo's continued effort to drive the pack members away from Scott, he went on to suggest that perhaps they should tell Scott what happened, since his behavior toward Corey seemed to suggest that maybe he would be more open to their kills in self-defense. Theo then left to go to AP Biology class, where he sat behind Scott and informed him that he needed to tell Scott something about Stiles later.


However, before Theo could tell Scott what he wanted to say, the two were distracted by the fact that Corey had begun projectile vomiting black blood and modified mercury, indicating that he was a "failure" like the other Chimeras. When Scott was so horrified that he was frozen in shock while watching Corey, who was screaming at everyone to not let the Doctors kill him, being loaded into an ambulance, Theo snapped him out of it and insisted that they needed to follow the ambulance to protect Corey.


On the way there, Scott asked Theo what he wanted to talk to him about, and Theo claimed that it wasn't as important as what they were doing now, leading Scott to insist that he tell him, since he believed that they all needed to start being more open and honest with each other. Theo then told Scott about Stiles killing Donovan, but changed the story; according to Theo, he saw Stiles brutally beat Donovan's skull in with a wrench at the high school, and though Theo claimed it could have been self-defense since Donovan had insinuated he wanted to kill Sheriff Stilinski, Theo framed it as though he didn't quite believe it. When Scott refused to believe that Stiles could do such a thing, Theo showed him the bloody wrench that Stiles had truly used to defend himself against Donovan, leading Scott to be confused and concerned about what was going on.


At Beacon Hills Memorial Hospital, Scott and Theo arrived to find that many patients, doctors, and nurses had been harmed in what looked like a fight and were in the middle of patching each other up in the halls, causing them to realize that Corey had done it, though Corey was using his Chimera power of supernatural camouflage to make himself invisible so they couldn't see him. By the time Scott and Theo finally tracked Corey down, he had been killed by the Dread Doctors in the ambulance bay, devastating Scott. Theo insisted that they needed to leave and find Hayden, since the Dread Doctors would be going after her next, and the two left to go to Sinema, where Hayden and Liam were in the middle of collecting Hayden's paycheck so they could leave town.


When they finally made it to the club, Liam was already in the middle of a fight with The Surgeon and The Pathologist while The Geneticist cornered Hayden in a back hallway. Scott jumped into the fight first to help back Liam up, and Theo entered the battle last, just in time for all three Werewolves to be incapacitated by the Doctors. Theo quietly reminded The Surgeon that he needed more time while he was held in a choke-hold, and The Surgeon maintained that he had until the supermoon to do what he needed to do before letting him go; fortunately for him, Scott and Liam were too disoriented from their beating to hear their conversation. When the three finally left to find Hayden, they found her in the middle of being given an overdose of modified mercury by The Geneticist, causing her eyes to turn completely silver as the mercury formed a nictitious membrane. Scott instructed Theo and Liam to get Hayden to the animal clinic and assured them that he would meet them there.


On the way to the clinic, Hayden was starting to get weaker and weaker from the overdose the Doctors gave her, and Liam became desperate in his attempts to save her. When Liam asked Theo what they could do to help her get better, Theo insisted that he had no idea-- while he knew how to treat wolfsbane poisoning (i.e. by burning it out), he had no idea what mercury did to Chimeras, especially since the mercury had been modified by the Doctors. Liam brought up the fact that she had an accelerated healing ability like them, and Theo reminded him that, as a Chimera, she wasn't really like them, comparing the Chimeras to "cheap knockoffs" of true shapeshifters like Werewolves and pointing out that she might not be as strong as they are.


This caused Liam to realize that if she had the healing ability of a real Werewolf, she could get better, but when Theo rudely retorted that, as Betas, neither of them had the power to give her the Bite to turn her, Liam reminded him that Scott, as an Alpha who had turned him into a Werewolf, could turn Hayden as well. This seemed to give Theo an idea about how to become a true Werewolf himself in case his original plans did not work out as intended.


At the animal clinic, after Scott confronted Stiles about what Theo had told him, and Stiles, in his fear and anger, unknowingly confirmed Theo's story despite it not being true at all, Scott went into the animal clinic to find Liam and Theo with Hayden, who was barely conscious. Theo watched as Liam pleaded with Scott about Hayden's condition and insisted that he give her the Bite, and Scott, exhausted and devastated by his fight with Stiles and too concerned about Hayden's well-being to risk it, said no.


In Status Asthmaticus, Theo watched as Scott and Liam debated whether or not to give the dying Hayden the Bite, and when it became clear that Scott wouldn't do it out of fear of killing her, Theo suggested that they needed to do something because Hayden wasn't looking good. The stress of the argument caused Scott to have an asthma attack, and Theo pulled an inhaler out of his pocket and tossed it to Scott to use to "help" him.


The next morning, Theo was seen at the animal clinic with Scott, Liam, and Hayden when Melissa McCall showed up with IV bags of chelation therapy in hopes of flushing the Dread Doctors' modified mercury from Hayden's bloodstream. When Liam, already getting aggressive from the supermoon's effects despite it still being daytime, inadvertently grabbed Melissa painfully by the wrist, Theo reminded them all that they were there to save Hayden's life, not kill each other. Melissa, who was confused by Liam's behavior, asked what was going on, leading Theo and Scott to explain how Werewolves can be affected by the supermoon even during the day because of how much closer the moon is to the Earth.


Scott and Theo moved into the waiting room to give Melissa space to work, where Theo pointed out that they were going to need help handling Liam since he was still new to lycanthropy. When Scott insisted that Liam would be all right, Theo reminded him that Liam was sixteen and in love, which, combined with the supermoon, would be a bad combination. Theo asked him if he remembered what first love feels like, Scott, likely thinking of his former relationship with Allison Argent, assured him that he did. Theo maintained that they needed help and reminded Scott that he needed the support of his pack, and when Scott glumly replied that he wasn't sure he had one anymore, Theo offered to talk to the others to get them to understand what was going on. Later, Theo left to go to the high school, where he texted Scott to let him know that the school was crawling with police officers due to one of the Chimeras destroying it the previous night.


Meanwhile, Lydia was at the library, reading a book about the Wild Hunt that led her to realize that Jordan Parrish was a Hellhound. Just then, she began to get an auditory Banshee premonition that began with unintelligible whispers that grew into the sounds of Werewolves battling each other, finally ending in Scott's voice saying "I can't let you kill me." Just as Lydia realized what was about to happen there that night, Theo appeared behind her and correctly guessed that Lydia knew what was coming. When Lydia anxiously replied that someone was going to die there, Theo confirmed her premonition before insisting that he couldn't let her leave to warn anyone. Lydia, confused, asked him what he was talking about, but Theo would only cryptically explain that he wanted Lydia and the rest of the McCall Pack and would be giving her time to think about her options before he backhanded her so hard she was knocked unconscious.


After bringing the unconscious Lydia to the Dread Doctors Operating Theater, Theo fully-shifted into his wolf form and ran into the woods, eventually finding Malia in her former coyote den, where she was staring at her sister's baby doll and recalling the events of the car crash that led her to accidentally kill her mother and sister. When Malia turned around and saw the wolf, she was shocked when it transformed into a naked Theo, causing Malia to demand to know how he full-shifted. Theo offered to teach her how to do it, and when Malia remarked on the fact that he was still naked, he insisted that he had nothing to hide.


He went on to ask her if Scott knew about her plans to kill her biological mother, and when Malia looked uncomfortable, Theo assured her that he wasn't judging her, and that he was actually interested in helping her because he knew that Scott wouldn't. He pointed out that if Scott wasn't willing to kill when necessary, then someone else needed to take the lead, and informed her about Hayden being near-death and the two Chimeras who still needed to be identified. When Theo insisted that the pack needed Malia's help, she agreed to go with him to Beacon Hills Memorial Hospital, only for Theo to lock her in a supply closet and throw the key in a sewer before he returned to the high school. He also used Lydia's stolen cell phone to text Scott and instruct him to go to the library, which he had partially surrounded with Mountain Ash.


Scott didn't notice the mystical barrier until it was too late, and he was shocked when he saw that Theo was able to complete the circle with a handful of ash without any difficulty. Scott correctly guessed that Theo was actually a Chimera and not a true Werewolf, which Theo confirmed by stating that he was actually the first Chimera, and that it was his Werecoyote side that Scott and the others didn't notice, a trait which he claimed made Malia more trusting of him despite her not truly knowing why. Theo also complimented Scott on his idea to call the Dread Doctors' creations "Chimeras," because not only does it mean "a creature with incongruous parts," but it also means "something impossible to achieve," or "an unrealizable dream."


When Scott snidely asked him if the Doctors successfully "realized" Theo, Theo's smug smirk dimmed slightly as he replied that the Dread Doctors came close to a success with him, but not completely, claiming that not all of them could be True Alphas. When Theo stepped out of the circle of mountain ash, Scott lunged for him so hard that he hit the barrier with enough force that it painfully threw him backward, and Theo laughed hysterically and claimed that even he felt the hurt of that blow. Scott demanded to know what Theo's plan was, but the Chimera refused to tell him, instead insisting that he would simply have to find out for himself before using the cell phone jammers that Parrish made to ensure that Scott couldn't call for help.


After Theo left, Scott made it up to the roof to see if he could escape Theo's trap by jumping off, only to find that he had made a mountain ash barrier around the outer perimeter of the building as well. When Scott began to wheeze, he took out his inhaler and took a hit of it before angrily squeezing it in his hand, crushing it to smithereens. A purple mist escaped from his closed fist, leading Scott to realize that Theo had laced his inhalers with wolfsbane to ensure he would be too weak to fight back, which is what had triggered his relapsed asthma. At some point, Theo broke the barrier long enough to let Liam in after using the effects of the supermoon to manipulate Liam into killing Scott, claiming that if Liam did so, he would become an Alpha and could then give Hayden the Bite to save her.


During the fight between Scott and Liam, Scott insisted that he couldn't let Liam kill him, because Theo needed that to happen since only a Beta bitten by a True Alpha could take that Alpha's power; once Liam killed him and became an Alpha, Theo could then kill Liam and become an Alpha himself. This argument didn't sway Liam, though, and it wasn't until Mason showed up to tell Liam that Hayden had died from her mercury overdose that Liam stopped attacking Scott.


Meanwhile, Theo had met up with Stiles where Sheriff Stilinski had hidden the bodies of the Chimeras from Parrish, where Theo revealed his true plan-- he wanted to become a real Werewolf and an Alpha so that he could take the McCall Pack for his own, which included Malia, a Werecoyote with natural killer instincts; Lydia, a Banshee surrounded by death; Kira, a powerful dark Kitsune; Liam, a Beta with "anger issues," and Stiles himself, who still had vestiges of "Void Stiles" inside of him. When Theo remarked that his new pack didn't include Scott, Stiles started to attack him, leading Theo to laugh and taunt him about having more blood on his hands than any of them. Theo then revealed that he would tell Stiles where the injured Stilinski was, but only if he promised not to help Scott.


After Liam had left the school, Mason helped Scott to his feet, and the two talked about what had happened, not noticing that a furious Theo had arrived to finish what he started. He berated Mason for not being able to wait five more minutes for Liam to kill Scott and backhanded him across the face before turning his attention to Scott himself. He stated that he should have stayed to make sure Liam could get the job done, but Scott, still weakened from the wolfsbane and the fight and devastated enough by this turn of events that he did not care if he lived or died, smirked and pointed out that now Theo would have to kill him himself, taking pleasure in the fact that if he did die, Theo still wouldn't get his power.


When Scott insisted that the members of the pack were still loyal to him, Theo conceded that he might be right, but that they will eventually come around; however, Scott made it clear that they wouldn't for him, because they're not like Theo and never will be. Theo, already insecure about not being a true supernatural being, demanded to know if Scott was insinuating that they wouldn't join him because he's a Chimera and not a real Werewolf, but Scott stated that it was because Theo is barely even human. Furious at Scott's words, Theo impulsively stabbed Scott in the chest with his claws and twisted his insides until Scott's red Alpha eyes faded away.


Afterward, Theo returned to the operating theater, where Lydia had just awoken after being knocked out. He apologized for what he was about to do, since he hadn't had any practice, and when Lydia realized that Theo planned to perform the memory-manipulation ritual on her, she pleaded with him not to as he stabbed his claws into the back of her neck.


He then sifted through her memories until he gained the location of the Nemeton before dropping Lydia unceremoniously onto the floor and using one of the Dread Doctors' large syringe guns to draw up a large amount of the green fluid from Der Soldat's tank. Despite the fact that the trauma of the ritual had put Lydia into a catatonic state, he still dragged her to the Nemeton with him and forced her to watch as he used the green serum to resurrect four of the numerous dead Chimeras that had been deposited there by Parrish while in Hellhound-mode. After using the serum to revive Tracy Stewart, Josh Diaz, Hayden Romero, and Corey Bryant, he informed them that they were his new pack, and he was their new Alpha, before leading them out of the woods.

In The Last Chimera, Theo appeared in the flash-forward to the events of Amplification, during which time he and the rest of the Chimera Pack broke into Eichen House to try to capture Lydia Martin before the McCall Pack could save her, as they believed that she could be used as bait to lure the Hellhound Jordan Parrish (and, by extension, the resurrected the Beast of Gevaudan as well)


However, even before Theo and his pack's arrival, Theo was the topic of conversation between Lydia and Gabriel Valack, the latter of whom was intent to learn what made Theo so special to the Dread Doctors so that they could eventually extrapolate the identity of who they were calling "the last Chimera." Valack, who had just performed trephination on Lydia's skull to amplify her Banshee powers, guided her through a premonition of the past when Theo let his sister die in the creek in the Beacon Hills Preserve.


Lydia eventually saw that Theo's sister's heart had bee removed, leading Valack to realize that, while there was nothing in Theo's medical records that indicated that he had a heart condition, it was likely that the Dread Doctors gave him a heart transplant so that he would have genetic chimerism that would allow them to make him into a pseudo-supernatural Chimera. When Lydia made it clear she didn't understand why Valack cared so much, he reminded her that there was a reason the Dread Doctors chose Theo and a reason why they changed their process, which would allow them to learn who the last Chimera was.


After Valack had Lydia run through what she remembered before Theo attacked her and used the memory-manipulation ritual on her, she brought up the symbol that Scott carved in the wall for Theo to find, which led Valack to realize that this was a sign that he intended to reunite the McCall Pack. However, when he asked her if this meant they would be coming for her as well, Lydia said that someone was coming, but it wasn't Scott McCall, indicating that she had a premonition of the arrival of both the Chimera Pack and Jordan Parrish. Just then, Theo, Tracy Stewart, Josh Diaz, and Corey made their way down the hallway through the closed unit.


Once inside, Tracy immediately lunged at Valack and pinned him to the wall in a choke-hold, but despite being choked, Valack insisted that Theo was making a mistake, and that since the Dread Doctors didn't realize how important Lydia is yet, Eichen House was the safest place for her. Theo ignored him and turned his attention to his "Betas" as Josh remarked that Lydia didn't look good, leading Corey to retort that having a bleeding hole in one's head wasn't a good look for anyone. When Theo saw just how badly Lydia's drilled skull was bleeding and how weak she looked, he sarcastically retorted that he couldn't believe that Eichen House was an actual medical establishment.


Valack, intrigued by Theo's motives, asked him what a pack of Chimeras needed with a Banshee, but Theo replied that he had no interest in a Banshee-- what he wanted was a Hellhound. Just then, Parrish, completely shifted into his flaming Hellhound form, appeared outside the closed unit and started to burn through the gate with his pyrokinesis to get to them. Valack looked smug when he pointed out to Theo that the Hellhound he wanted seemed to have arrived, but Theo just looked at Parrish in awe.


Meanwhile, in the present-day portion of the episode, Scott and Stiles lured Theo to the McCall House after figuring out what he had tried to do, with Scott hiding upstairs to monitor his heart rate without alerting him to the fact that he had survived his assassination attempt. Stiles had spread a line of Mountain Ash over the threshold of the front door, and Theo stared at him with an intentionally amused smirk as he stepped over it, remarking that it seemed like they were all telling the truth now. Theo then seemed to sense Scott's scent, but Stiles distracted him by throwing one of Scott's shirts at him to explain the scent before asking him if he really killed his best friend.


Theo told Stiles to be honest before asking him if Scott was really his best friend after everything that happened, but instead of answering his question, Stiles asked him if he intended to let his father die, too. Theo reminded him that if he wanted Stilinski to die, he wouldn't have told Stiles where he could find him, and he seemed shocked when Stiles demanded to know why the doctors at the hospital said that Stilinski was dying from some toxin or poison in his body.


Theo changed the subject to distract from the fact that he didn't know what Stiles was talking about and insisted that he wasn't the bad guy-- he was simply a survivor who was being realistic about what the town was facing. He went on to say that the others would act the same way if they knew what he knew, and when Stiles demanded to know what exactly Theo knew, Theo cryptically replied that he knew what was coming, and he knew what Parrish is because he saw it in Lydia's memories. Stiles reminded him that it was going through Lydia's memories that caused her to become catatonic, but Theo referred to Lydia's injuries as "collateral damage," which did little to endear Stiles to him.


Theo then made it clear that if what Lydia knew about Parrish was true, then things were about to get much worse in Beacon Hills. When Stiles insisted that he didn't care, Theo retorted that he should, because if Stiles' dad survived, he wouldn't be a Sheriff of anything much longer if what Theo knew actually came to pass. This made Stiles furious, and he got up to physically force Theo to tell him what was happening to his father, but Theo simply shoved him backward hard, causing Stiles to fall back against the staircase and fall unconscious before Theo left.


After Scott managed to wake Stiles up, they briefly discussed Stiles and Theo's conversation, during which time Scott admitted that Theo's heart only jumped once during the conversation, and that was when Stiles informed him of Stilinski being poisoned. Stiles was intent to go figure out what was going on with his father by himself, but Scott insisted that Stiles let him come with him, since he needed help. When Stiles angrily retorted that Scott believed what Theo said, Scott reminded him that Stiles, too, trusted Theo in the end, and that he got to all of the pack members.


Meanwhile, Theo had caught up with the newly-resurrected Hayden Romero, who was helping him find Noah Patrick, the Chimera that Theo had sent to attack Stilinski, who they knew was being pursued both by the Dread Doctors (for being a failure) and by the McCall Pack (to get answers about what he did to Sheriff Stilinski). Hayden sensed that Noah was close and, confused by this sensation, asked Theo how she knew that, which led Theo to inform her that, since she was part-Werejaguar, and Noah was part-Berserker, they had a connection that allowed her to keep tabs on his current state.


As they continued to search, Hayden sensed that Noah was dying, and Theo seemed upset by this ending, as he thought Noah would have been a good addition to their pack. They then came upon a large circle carved around a smaller circle in a corrugated metal wall, the sight of which shocked Theo. When Hayden asked him what it was, Theo explained that it was the symbol of an Alpha and his pack-- specifically, Scott McCall and the McCall Pack.


In Damnatio Memoriae, Theo helped Josh and Hayden learn how to use their Chimera powers and got to know them all better, allowing him to learn better ways to control and manipulate them. He also went with Tracy to Beacon Hills Memorial Hospital, where she went to visit the prison transport van driver that she mauled in Dreamcatchers the same night that she killed her father and psychiatrist. The driver became terrified by the sight of her, and Theo pushed the nurse call button out of his reach before offering to take care of him for Tracy, stating that all she had to do was ask for his assistance.


However, instead of taking his offer, Tracy told him a story about how her father, a public defender, once represented a man on death row, and explained what she had learned about how lethal injection worked. She told him that they give death row inmates a medication that paralyzes their diaphragm so they can't breathe as she used her claw to drip her Kanima venom into the driver's IV bag. Moments later, the man began to gasp for breath as though he was being smothered before he died as a result of the venom in his veins, and Theo looked at Tracy proudly.


The next day, Theo sent his so-called Chimera Pack after Scott when they found him and Stiles investigating the Beast of Gevaudan. However, though Tracy was able to paralyze Stiles, Scott was able to easily defeat the Chimeras by getting Tracy and Josh to neutralize each other with their powers and scaring Corey so much that he was too afraid to try to fight him. Theo then appeared and was clearly irritated by his pack's inability to take Scott down.


When Scott demanded to know what Theo had done (since he was not aware that Tracy, Josh, and Corey had been resurrected until now), Theo remarked that he made new friends and stated that he didn't take rejection well in reference to his battle with Scott in Status Asthmaticus. When he realized that both Scott and Stiles were still wary of him, he insisted that, contrary to their beliefs, they were actually on the same side again, as they were going to need to work together to face what was coming with regards to the Beast, who he claimed was the real enemy.


In Codominance, Theo and Tracy worked together to track the Beast to the high school, though Theo made sure to emphasize that they were only tracking him down at this time and were not planning to try to fight or capture it yet. Upon entering the school, Theo's eyes flashed gold as he used his supernaturally-enhanced sight to see the "DAMNATIO MEMORIAE" message the Dread Doctors had left on a row of lockers.


Tracy asked about the message, Theo explained that the Doctors were trying to get the Beast to remember who it really is and revealed that the Dread Doctors needed to create the perfect Chimera in order for the spirit of the Beast to possess it, since they couldn't simply resurrect it out of thin air. He went on to explain that the still-unidentified Chimera host was just a symptom, and that they probably had no idea that they were transforming into the Beast at night, just like the Beast didn't know it was turning back into human form during the day.


When Tracy brought up the fact that she had read that the Beast killed over one hundred people in the 18th century, Theo smirked and corrected her, claiming that the Doctors had told him that the number was closer to five hundred. Suddenly, they heard the sound of the doors opening at the end of the adjacent hall, leading Theo and Tracy to walk down the hall as the latter flicks out her claws in anticipation for a fight. When they turned the corner, they found the Dread Doctors waiting for them at the end of the hall, and Tracy wasted no time attempting to attack them, though The Pathologist backhanded her across the face so hard that she flew backward, sliding across the floor and hitting a row of lockers.


Theo, both annoyed by their interference and frightened by their presence, turned to address them. When The Surgeon curtly ordered them to leave, Theo continued to stand his ground despite his fear and demanded to know where the Beast was, but instead of answering, The Surgeon simply reminded him that he already had his pack, which meant that their deal had concluded. This statement angered Theo, and he allowed his gold Chimera eyes to come out as he insisted that what he had wasn't enough, because he was neither an Alpha nor a real Werewolf as he had intended, and though he didn't mention it, his expression implied that he believed the majority of the Chimeras in his pack were a poor consolation prize. The Dread Doctors remained silent, and before Theo could react further, they began to hear footsteps approaching them that were so powerful that the ground literally quaked beneath their feet.


Sure enough, the Beast finally stomped toward them, stopping just behind the Dread Doctors before he tossed a round object at Theo; when it landed near Theo's feet, it was revealed that the object was the severed head of a male teacher whom the Beast had just slaughtered. Tracy, still recovering from her fight with The Pathologist, gasped at the sight of it, and Theo only became more scared as the Beast roared so loudly that both Theo and Tracy quickly covered their ears and squeezed their eyes shut, clearly in pain due to the decibel level of the roar affecting their supernaturally-enhanced hearing. When the roaring stopped and they could finally let go of their ears and open their eyes, both the Dread Doctors and the Beast had vanished, leaving the two Chimeras horrified by why they just witnessed.


The next day at school, Theo stopped to talk to packmate Hayden at her locker, an act that seriously angered Hayden's boyfriend, Liam Dunbar, who watched from a distance. Theo seemed to be aware of Liam watching them and how angry he was making him and purposely smirked at the young Beta just to rub it in that his girlfriend was in Theo's pack and not Liam's. Later, while in Ms. Fleming's senior math class, the teacher was taking attendance when she asked if anyone had seen Stiles, Scott, or Lydia, causing Theo to smugly report that Lydia wouldn't be in class for a while due to "medical issues." Just as he said this, Malia, who was walking down the hallway, apparently heard this remark and stopped outside the door to the classroom, glaring at him angrily for what he did to Lydia, Scott, and the rest of her pack. When Theo shot her a smirk in response, she lost her patience with him and simply walked away.


After school, Malia, who had earlier learned that Alan Deaton had been captured by her biological mother the Desert Wolf, went to the animal clinic to try to find some clue as to where her mother could have take him. It was there that she was found by Theo, who smugly and correctly guessed that Malia couldn't find Deaton before remarking that since she probably had no idea where to start, she would never find him in an effort to goad her into attacking him and tapping into her dark side. When Malia glared at him furiously, Theo only became more pleased that his attempt to bait her were working and smirked before remarking that Deaton was probably already dead and wondering aloud what Scott would think when he found out that it was Malia's fault that his mentor and Emissary was captured.


This taunting suddenly achieved Theo's desired reaction, as Malia growled furiously before lunging toward him, shoving him in the chest so hard that he flew backward into one of the file cabinets behind him in the exam room. She then quickly pinned him against the wall in a choke-hold as she wrapped one hand around his throat and punched him in the face several times with the other. When she growled that she should kill him for what he's done to her and her loved ones, Theo continued to smirk as he reminded her that while she probably should, she ultimately wouldn't because she liked him too much.


This statement only made her more furious, so Malia began punching him even more before shoving him into another cabinet and then flipping him on his back on the metal exam table in one fluid motion as she broke his arm. Though Theo did groan in pain, he still seemed to be enjoying Malia taking her anger and frustration out on her, especially when she jumped onto the table, straddled his hips, and pummeling him in the nose and mouth with her fists.


However, when he began to laugh hysterically, she got angry and stopped what she was doing, allowing Theo to remark that he also let Stiles "kick his ass," but that, unlike Malia, he didn't break any of his bones. He reached over and snapped his broken arm back into place with his uninjured hand before giving Malia a serious look, triggering her anger again and causing her to almost deliver the killing blow before Theo verbally stops her. He admitted that he could help her find both Deaton and the Desert Wolf, and when Malia suspiciously asked him how he could do that, Theo revealed that he knew how the Dread Doctors found everyone, implying that they could use the same method to find the aforementioned duo.


At the end of the episode, just after Scott had returned to the McCall House after having rescued Kira and Noshiko from the Skinwalkers in Shiprock with Stiles, Liam and Mason showed up and woke Scott and Kira from their nap. They then revealed that Mason had learned about some of Theo's plans from Corey, specifically that he was looking for a blind Alpha that Scott immediately realized was Deucalion.


In The Sword and the Spirit, Theo, under the guise of making good on his previous promise, informed Malia that he would help her find her biological mother, but stated that what they needed to track her down was in the Dread Doctors Operating Theater. He went on to explain that he couldn't let Malia know where the operating theater was and proposed that he inject her with the same modified form of Wolfsbane that the Dread Doctors used on Liam (and which the Chimera Pack would later use on Deucalion) to sedate her while he brought her there. Though Malia initially rejected this proposal, her desire to bring Alan Deaton back safely and to kill the Desert Wolf won out, and she reluctantly allowed him to inject her neck with the Wolfsbane, coyote-ing out in the process.


Theo then brought Malia back to the operating theater, where he strapped her down to the exam chair before she woke up. When she regained consciousness, she was furious that Theo would restrain her in this way, but Theo insisted that it was to keep her from hurting herself or others during the process to locate the Desert Wolf. He then showed her a set of goggles the Dread Doctors created that can hone in on a specific frequency, allowing them to track the Chimeras with the unique frequency they were each given; since the Desert Wolf was a Werecoyote, she, too, had her own unique frequency that could be tracked with the goggles.


However, the goggles had a row of spikes around the rim of the eyeglass that needed to be shoved through the skin and tissue surrounding the eyes, which gave Theo a certain amount of amusement as he showed her what she needed to do. He then instructed her to think of her memories of the car crash that killed her adopted mother and sister in order to hone in on the Desert Wolf before flicking the switch to impale the spikes through her facial skin. When Malia began to scream and close her eyes in agony, Theo insisted that she open her eyes so she could see her biological mother's location, allowing them both to figure out that the Desert Wolf was hiding out in Fort Jewett.


Theo and Malia then met up with Braeden at the Beacon Hills Animal Clinic so the three could come up with a workable plan to infiltrate the Army base. When Braeden aimed her shotgun at Theo and stated that she should kill him for nearly killing Scott, Theo smirked and pointed out that he technically did kill Scott before reminding her that a shotgun wouldn't be enough to kill him. Malia went on to insist that Theo come with them on the mission, a plan with which Theo claimed he wanted to help. Despite Braeden's reluctance to infiltrate a base she knew nothing about, she ultimately agreed for Malia and Deaton's sake before the three set off for Fort Jewett.


When they got there, Braeden noticed that there was seemingly no guards or anyone else in the base, which only made her more reluctant to continue Malia and Theo's mission. Malia insisted that they needed to do it before she noticed a strange scent that she tried to cover up. Once inside, it was revealed that Theo had double-crossed them by working with the Desert Wolf when he yanked Braeden's shotgun out of her hands, knocked her out, and then shot Malia in the stomach with it. He went on to say that he assumed the scent Malia had caught earlier was his own regret and claimed that he didn't have a choice before sliding the gun toward Corinne. She then tossed him a jar containing Belasko's talons, which glowed blue in Theo's presence and caused his own eyes to glow yellow.


Having gotten what he came for, Theo left with the talons and returned to the operating theater, where he found Tracy, Josh, and Corey laying injured around the laboratory. Theo asked them if it really took all of that effort just to neutralize one single blind Alpha, Deucalion's voice was heard from the next room, saying that he had recently been re-blinded due to Jennifer Blake's Darach healing supposedly wearing off. When Tracy informed Theo that Deucalion already knew about the Beast and why they were there, Deucalion, who was hooked up to an IV of modified wolfsbane, pointed out that the Beast of Gevaudan was history's most famous and feared Werewolf before asking if he really thought he would tell him how to steal his power. Theo recognized where Deucalion was coming from and retorted that he's smart enough to know they could come to some kind of an agreement before asking him what it was he wanted. When Deucalion replied that he wanted Scott's eyes skewered on his claws, Theo smirked in satisfaction, indicating that he liked the sound of their deal.


In Amplification, Theo along with his pack break into Eichen House. Josh and Tracy take out the guards. They enter through the lobby and demand to see Lydia Martin. He pulls the guy from behind the desk through the glass and onto the floor. As they approach Lydia's room, Theo signals Tracy to get Valack. Valack wonders what they would want with a Banshee, so Theo replies that he doesn't want a Banshee, he wants a Hellhound. At that moment Parrish appears at the door, he burns the door down and begins walking towards them.


In Lie Ability, Theo watches as the Hellhound walks towards him, he grabs Lydia and presses his claws against her throat with such force that she begins to bleed. He then orders Tracy, Josh and Corey to take out the hellhound , Corey is hesitant but Tracy and Josh go right after him. Valack sneaks up behind him and drills a hole in Theo leg with his trephination tool and he falls, Valack grabs Lydia and they get away. He gets up and throws a pipe at Parrish, it pierces his chest, the hellhound falls to the ground and reverts back to human form. He teams up with Stiles in order to find Lydia, they soon realize that Valack has taken Lydia somewhere within the tunnels.


He loses Lydia's scent after entering the tunnels, all that he can smell is chemicals and fecal matter, now he's trying to see if he can hear her. He wants Stiles to trust him because he'll never find Lydia by himself but Stiles refuses since he basically killed his sister. Theo says that he was only nine, so when three people in leather suits showed up and said that his sister wanted him to have her heart, he believed them. Then they hear a loud scream and Theo say it came from everywhere. He and Stiles get into another argument and he reveals that he's going to steal the beast powers, then Through Stiles advice, Theo breaks the pipe in order to hear better.


Theo and Stiles eventually find the room that Lydia is in, and after Theo breaks the door, Stiles goes in and saves Lydia. In this room, he finds a mask that looks very similar to the Dread Doctors' masks. Back at the lair with Hayden and Deucalion, Theo reveals to them that he didn't find what he was looking for but he may have found something better.


In The Beast of Beacon Hills, Theo is in his lair along with Tracy, Josh and Deucalion. He request that Josh put the mask on but he refuses. Tracy brings him Belasko's talons but he can't do anything with them as long as The Beast's identity remains a secret but Deucalion tells him they're completely useless. As Deucalion continues to to talk and piss him off, he orders Tracy to paralyze him but Deucalion gets up and pulls the tube out of his arm thus revealing that he's been a willing prisoner. Theo is slammed against the wall by the blind alpha, his arm is broken and then Deucalion explains that the secret to taking power is pain, Theo has to take their pain, then their life, and then their power.


He tests this process by killing Josh, Theo impales Josh with his claws and takes his power by doing this, Theo's eyes visibly becomes brighter, with Josh's abilities, he now has the power to put on the mask, he does this but appears to be in pain. Theo forms a temporary alliance with Scott and Liam, they meet up at the Operating Theater where Theo explain how the Dread Doctors have managed to expand their life, they've been using a German soldier known as "Der Soldat", he was a Nazi Alpha Werewolf. As they look for Mason, he informs them that when he put on the mask, he saw a man dying in the snow, impaled by a spear. They find Mason but the Doctors show up, it was clearly a trap, The Surgeon taunts Theo by calling him a "failure", he becomes enraged and attacks the doctors. Soon after, Mason becomes the beast and Theo watches as he kills The Geneticist and The Pathologist.


In Apotheosis, Theo is wounded after is confrontation with the Dread Doctors and The Beast. Tracy takes him back to the lair and sits him down, they begin to kiss but Theo is too hurt. Tracy suggest that they rest for a couple days and think of a new plan but he already has a new plan. Theo kills Tracy and takes her powers. Now he and Deucalion are in the tunnels, Deucalion encourages him to be at full strength, he tests this out by grabbing a circuit box and then shocking Deucalion and leaving him on the ground.


He finds Scott, Liam and Lydia in the tunnels, after shocking Scott and Liam, he throws Lydia down a whole. Theo shifts and proceeds towards The Beast, he doesn't want to steal its name, he just wants the power; however he fails. Sebastien Valet is too strong and he knocks Theo to the ground, as Sebastien walks off, he sees Deucalion, Scott and Liam coming his way. He realizes that Deucalion was working with Scott the entire time and then he gets his neck snapped. Shortly after this, Theo is looking for revenge, he has lightning scattering around his body, he shoots a bolt of lightning but Kira blocks it and tells him that the skinwalkers have a message for him. Kira stabs the ground with her sword and it cracks, his sister comes reaching out the ground and pulls Theo in. No one comes to save him even as he begs for Scott's help.

In Ghosted, Liam Dunbar and Hayden Romero, at a loss for options as to how they could absorb enough lightning to lure a Ghost Rider into a trap, summoned Noshiko Yukimura to the underground tunnels to ask for Kira Yukimura's magic katana so that they could free Theo and utilize his stolen electromagnokinetic powers. Though Noshiko insisted it was a bad idea, she entrusted Liam with the sword, believing Kira would want her to do so; even so, she reminded Liam that anything that Theo did after he was released would be his responsibility.


Just as Liam was about to plunge the katana into the ground, Hayden attempted to stop him, but was unable to do so in time. The ground opened up as Theo punched his way back to the surface. When he crawled out of his prison, he extended his claws and fangs and growled at them before lunging at Liam and pinning him against the wall. Hayden assured him that they weren't trying to hurt him and that they were actually the ones who set him free. Theo demanded to know where his sister was, and when Hayden and Liam reminded him that he killed her years ago, Theo became angry and insisted that he was going to kill all of them. Hayden, afraid of what Theo could do, begged Liam to send him back, but since Liam knew they needed Theo's help, he instead showed Theo the katana and informed him that they needed his power to save Beacon Hills, and that killing them would make him worse off than ever. Theo argued that nothing could be worse than what he went through, which Liam seemed to understand before asking him if he knew what the Wild Hunt was.


Theo, Hayden, and Liam then joined Garrett Douglas (who recognized Theo, and whom Theo recognized as Der Soldat, the captive Nazi Alpha Werewolf the Dread Doctors used to help extend their live by using his healing factor to create the Dread Doctors' green serum) in another conjunction in the tunnels. Garrett set up the lightning rod they had, which Theo examined before asking them how they knew his part of the plan would work. Liam reminded him that he stole Josh's power and assured him he could do it, but when Theo grabbed the lightning bolt and Garrett set the dial to 1,000,000 joules, he was violently shocked and thrown backward several meters. Liam angrily asked him what happened, and when Garrett brought up the fact that the voltage he used was only 20% of that in a bolt of lightning, Theo got up off the floor and sarcastically retorted that he was fine before thanking them for their lack of concern.


After considering this reaction for a moment, Liam realized that Theo no longer had Josh's power, leading Hayden to examine his claws and determine that he no longer had Tracy Stewart's Kanima powers either. Theo remarked that he was back to "Classic Theo," but Liam, already annoyed by Theo's attitude, pointed out that maybe he should try feeling some remorse, considering he killed both Josh and Tracy for their powers in the first place. When Theo smirked and replied, "I just put them back the way I found them," Hayden lost her patience and once again told Liam to send him back. This reaction alarmed Theo, who immediately began arguing that he could still help them by sharing the information he learned about the Wild Hunt from the Dread Doctors before insinuating that he knew things about Garrett that the others didn't know. Garrett, afraid that Theo will divulge his secret of being Der Soldat, stated that he was in agreement with Hayden.


Visibly unwilling to go back to his underground prison, Theo asked who was making the pack decisions before then asking where Scott and Stiles were. Hayden and Liam were stunned that Theo remembered Stiles, and when Theo, confused, asked him why he wouldn't, Liam realized that Theo could be useful to them after all.


That evening, Theo got cleaned up and accompanied Hayden and Liam to the McCall House, where Hayden pointed out that Theo knew about the Ghost Riders before asking him how they could get Stiles and the other erased victims back. Theo, looking grim, insisted it couldn't be done, as the Wild Hunt comes to a location and leaves with their captives. When Liam brought up that the Ghost Riders were still taking people in Beacon Hills, Theo, stunned, insisted that it wasn't possible, implying that the Wild Hunt isn't known for staying in one place for long. Theo then realized that it was possible that the Ghost Riders were stuck in town, which was why they hadn't left yet. However, despite this theory, Theo insisted he didn't know what to do, but Liam once again held up the sword and argued that if he didn't help them, he would go back to his prison. Despite Theo's fear of going back, he smirked as he realized that Scott had nothing to do with Liam's plan to free him.


A short time later, Scott returned home and was stunned speechless when he realized that Theo was standing in his kitchen. As he glared at Theo, Theo nervously joked that he assumed they weren't just going to "hug this out." When Scott growled that it was taking all of his strength not to tear him in half, Malia, having overheard their conversation, walked into the kitchen and glared at Theo when she noticed his presence. Theo looked even more scared and anxiously joked, "You aren't still mad about the whole shooting-thing, are you?", causing Malia to become so angry that she partially shifted and roared before lunging at him.


In Heartless, Theo wakes up in the morgue of a replica of Beacon Hills Memorial Hospital and a female voice whispers his name over and over. Theo walks around the hospital and figures out who was whispering his name was his deceased sister Tara. He tries to escape but his sister pins him to the ground and rips out of his chest the heart he stole from her years ago. Theo lives this over and over, making it clear he was in an endless loop. When Theo didn't exit the morgue and Tara showed up again, Theo told his sister she didn't have to stop before getting his heart ripped out of his chest again.


In the present, Malia is beating Theo up while the latter, still dreaming with his sister, told her she din't have to stop. Malia, believing it was meant for her, flicks out her claws and intends to kill Theo but Scott and Liam hold her back. Scott assures Malia Theo is going back to Hell but Liam tries to convince them, in vain, they could use the information Theo possesses about the Wild Hunt to defeat the Ghost Riders but Scott and Malia are more than certain Theo'll betray them again and kill them so he orders Liam to send him back to the Skinwalkers. Theo comments "Except Liam's the one with the sword." and the others all yell at him "SHUT UP!!!". Scott takes Liam with him to talk to him privately while Malia advances toward Theo with the intention of killing him, forcing Hayden to stand in the middle of the two coyotes. Theo attempts to calm the Desert Wolf's daughter by saying "Okay, look, I know that there's mixed feelings all around. But I might be your only option to stop the Wild Hunt." but this still doesn't save Theo from Malia's rage.


In the living room, Scott tries to reason with Liam that Theo is still the psychopath that once broke them up and manipulated Liam into killing Scott but when Liam failed, Theo finished the job and killed Josh and Tracy for their powers and his own sister in cold blood. Liam tells Scott that using Theo might be a mistake and reminds him he has done mistakes as well while learning to be an Alpha. Scott agrees with that but says they don't have time for mistakes and adds he doesn't want to lose Stiles so Liam convinces him to use everything they have.


Liam makes a deal with Theo: if the Chimera promises to help the pack in catching a Ghost Rider, he won't be sent back underground but if he tries to kill them or something else, he'll be sent back to the Skinwalkers. Theo agrees to these terms and tells them they're gonna need a transformer and he knows the location of one. However, he'll only reveal the location if Malia promises not to kill him. Liam agrees but Malia is offended by it and leaves the house saying she has an idea that "may not be better, but at least, it's not him [Theo]".


Theo has told the pack the Dread Doctors owned a transformer in their lair in the woods but Liam and Hayden handcuff the Chimera's hands to make sure he doesn't escape from them and because they still don't trust him. Liam thinks it was a bad idea bring Theo back but Hayden assures him they took a risk and begin to kiss, leading Theo to ask "You guys want me to leave you alone?" but reveals he can't because he is handcuffed. The three hear thunder and hurry for the Dread Doctors' lair in the woods, where the transformer is. Scott, Mason and Corey construct a metal cage so when the large electrical transformer turns on, it'll transmute the energy from multiple lightning strikes. After some time, their plan works and a Ghost Rider is trapped in the cage, covered in a Mountain Ash barrier.


Scott, Liam and Theo attempt to get the Ghost Rider talk about what he wants and how to get all the citizens of Beacon Hills back but with no success. They call Parrish, as they believe he has some kind of a connection with the members of the Wild Hunt and the creature telepathically says "We are the Wild Hunt. Those who hunt with us hunt forever." and "There is only the Hunt. No one resists. No one escapes.". The Rider begins speaking a rumbling language and it triggers Parrish's transformation into his Hellhound mode. He begins burning the Mountain Ash barrier to set the Rider free but Scott and Liam, with the help of their Werewolf enhanced strength and durability, take him outside while Theo quickly restores the barrier, only to find behind him Garrett Douglas, who shifts into his Werewolf form.


Theo tries to escape but Douglas stabs him in the back with his claws and forces him to break the barrier or he would be torn in half. Douglas kills the Rider and eats its pineal gland before he leaves with the Rider's whip. When Scott, Hayden, Mason and Liam return, they find the Ghost Rider dead and Theo cowering in the corner, leading them to believe Theo killed the Rider and was untrustworthy after all, leading Liam to hold the sword so he can banish him to Hell. But Theo assures them he had nothing to do with the Rider's death, but Mr. Douglas had.


In Blitzkrieg, Theo is locked up in a cell of Beacon Sheriff's Department and watched by Hayden, Liam and Mason, who are discussing how Garrett Douglas was able to kill a Ghost Rider as they believe it was something impossible. They say they would like to know what he knows about the Wild Hunt, which makes Theo volunteer to tell them everything he knows about Douglas, which makes the younger teenagers to look at him curiously.


But there's a catch: Theo will only tell them what they wish to know if they break Kira's sword, the only way to send him back to his underground prison but Mason, Hayden and Liam remain iffy. After convincing the trio he does not want anyone's pack or power but just to survive, Liam breaks the sword, which makes Theo smile.


Theo reveals Douglas is actually a Löwenmensch, a wolf/lion shapeshifter, and he was a part of the Ahnenerbe, Himmler's personal project to use the occult to win the war. One night, he and his fellow soldiers confronted the Ghost Riders in the woods next to a rift to the Wild Hunt but, when they were outnumbered, they retreated but Douglas escaped with an injury from a Rider's whip. He found the Dread Doctors and asked them to heal his injury but they had better plans for him and trapped him in the giant tank of green serum he was in until fall 2012. His injury infected the water of the tank and it mixed with the tank's fluid, making him stronger and absorbing the power for 7 decades. They realize Douglas know wants the Wild Hunt as his own supernatural army.


A Ghost Rider shows up and erases Mason, leading Liam to fight the Rider in order to avenge his friend. Hayden joins him but is caught in the Rider's whip and realizes she can't be free so she tells Liam to stick with Scott so they find a way to bring everyone back and she gets taken.

Personality[]

“ I'm not the bad guy, Stiles. I'm just a realist. I'm a survivor. If you knew the things that I know... ”

Theo is an intelligent and charming young man who has demonstrated an exceptional ability to use his cunning to manipulate others around him, as evidenced by the fact that he was able to convince everyone in the McCall Pack, as well as their allies such as Sheriff Stilinski, that he was a kind, compassionate person who simply wanted entry into the pack. Despite his compassionate and caring persona, he has shown himself to be ruthless in his pursuit of power, much like Peter Hale, and is willing to sacrifice anyone's life if he believes it will help him achieve his goals. Despite this personality trait, Theo has shown an uncharacteristic level of care and concern toward Malia Tate, who is a Werecoyote like him and who he seems to genuinely like, though that has not stopped him from hurting her physically and emotionally in order to get what he wants.

Throughout the fifth season, Theo's main drive in life was his desire to become a true Werewolf and an Alpha, which he believed would make him immensely powerful, especially if he became the Alpha of the McCall Pack, who are exceptionally powerful individually and would boost his potential power as well. To achieve this goal, he showed that he is capable of making elaborate plans to manipulate those around him, putting wedges between Scott and his packmates to drive them apart in hopes that, once Theo had stolen Scott's powers and had become an Alpha Werewolf himself, they would be willing to accept him as their new Alpha.

This plan also revealed that he is extremely good at reading people, and knows exactly what to do or say to manipulate them into reacting how he wants, whether it's proving himself to be trusted by saving the lives of the McCall Pack, making Stiles Stilinski feel better about killing Donovan Donati so he was more willing to accept his darker nature, or turning Liam against Scott by pointing out that taking his Alpha powers would allow him to save girlfriend Hayden's life, among many other examples.

“ He's using you, Liam. He wants you to be the Alpha because he can't take it from me-- only you can. But once you do, he'll take it from you. That's why he wants you to kill me. ”


However, though Theo made it clear that he wanted all of the members of the McCall Pack to be his subordinates, he was perfectly willing to sacrifice many of them if it meant getting the others. For example, Theo wanted Liam in his pack due to his immense strength and anger issues (the latter of which Theo believed could lead Liam to develop the killer instincts that Theo valued most in his associates) but was ultimately willing to kill Liam in the case that Liam was able to successfully kill Scott, since Liam, as the only Beta Scott had bitten and turned at that point, was the only person who could steal the Alpha powers Theo wanted from him, allowing Theo to thereby steal the Alpha spark from Liam by killing him.

In the same vein, Theo also wanted Lydia in his pack, as he knew her Banshee powers would be a valuable asset in predicting any threats against him, but when it became clear that he would be unable to turn Lydia against Scott, he believed he had no choice but to take Lydia out of the equation entirely, deciding instead to use her to find the location of the Nemeton by forcibly reading her memories; the fact that he referred to Lydia's resulting catatonia as "collateral damage" demonstrates just how much he used to base his value of other people on how much they could or could not help him get what he wants.

“ The problem is, though... sooner or later, physical pain, it's... it's manageable. See, real pain is emotional pain. That's the kind of pain that lasts. If you want to cause Stilinski that devastating, soul-crushing pain... You don't go after him. You go after someone he loves. ”


Theo has demonstrated traits of a sociopath from a young age, as evidenced by flashbacks to when he was around ten years old, in which he watched from the bridge in the Beacon Hills Preserve while his sister Tara pleaded for his help and did nothing to aid her until she died of hypothermia, as he wanted her heart so the Dread Doctors could turn him into a Chimera. This was also proven by Theo's impulsive behavior; though he was able to trick the McCall Pack into thinking that he was a good person and genuinely wanted to help them in order to get close enough to Scott and the others to steal Scott's powers, he was so upset when his plans failed that he impulsively killed Scott himself despite knowing that doing so would ruin his chances of taking Scott's Alpha powers for himself through Liam. He was also shown to be very knowledgeable regarding how to inflict the maximum amount of pain on others when he was instructing Donovan Donati on how to best get back at Sheriff Stilinski for what was done to him and his father.

Though he seems to have no issue with physically or psychologically harming people, he has also demonstrated a slightly masochistic enjoyment in others causing him pain as well, much like Ethan and Aiden. This was demonstrated when he intentionally encouraged both Stiles and Malia to beat him up and was pleased when Malia broke his arm in a fight, though this was likely due in part to Theo wanting the two to embrace their darker inner nature by engaging in violence regardless of the identity of their target. He has also shown behavioral similarities to Peter Hale and the Nogitsune in terms of his long-term plans and manipulation of others using their weaknesses against them.

“ You know, Theo, someday, your willingness to stab anyone and everyone in the back might turn out to be your downfall. ”
— Deucalion to Theo in Apotheosis


In addition to these personality and behavioral traits, Theo has also shown that he is a foil to Scott McCall; where Scott brings out the best in everyone around him due to his belief that everyone has the potential to be good, Theo wanted everyone around him to be as evil as he was and gained enjoyment in bringing out the darker nature in those around him; this was evidenced by his attempts to tempt Stiles Stilinski and Malia Tate into embracing their inner dark side to be more like him, as he deemed them among the members of the pack with the best chances of turning to his side. Likewise, while Scott gains the loyalty of his packmates and allies by treating them as equals and going out of his way to care for, protect, and defend them, Theo treated his packmates and allies, such as Deucalion, as pawns to be used as he saw fit to gain the power he craved. Theo's inability to pass up an opportunity to stab his allies in the back in exchange for power or other benefits ultimately became his downfall, as the fact that he did nothing to earn their loyalty led all of his allies who weren't killed by Theo himself to switch sides in the final battle.

After his imprisonment for a few months in the mystical prison, and his release, Theo's personality has changed. He has no longer shown any sign of his power hungry nature, seemingly content in simply living to survive in freedom. This change has also shown a somewhat selfless side to Theo's nature, in particular his actions towards Liam, as he saved Liam's life twice when they were facing the Ghost Riders, even allowing Liam to escape while he was the "bait” and protecting Liam when they were hiding from the hunters in the Zoo, even trying to help Liam talk through what was triggering him. This selflessness and caring is a new trait that even Theo himself seems to be conflicted about, as he still makes himself out to be the emotionless, power-hungry person he used to be while acting in ways that demonstrate the opposite.

One of the only traits of his that has not changed is his continued desire to be a real Werewolf in a real pack, which was shown when he tried to declare himself part of the McCall Pack during the fight with Garrett Douglas and the Ghost Riders, only to be rebuffed by Malia Tate. However, despite Malia's hesitance in believing in Theo's redemption, Scott spent Season 6B giving Theo chances to earn his trust, opportunities that Theo took in order to show that, despite his past behaviors, he is trying to be a better person.

Theo would continue to show his selfless side months later, suggesting he has come to genuinely start to care about the McCall pack, particularly Liam. Demonstrated when he continuously saved Liam from losing control and did his best to prevent him from killing, as well as in continuing to aid the pack in their battle against the Anuk-ite and Monroe’s army. This ultimately led to Scott entrusting Theo to find and protect Liam, his mother, Mason Hewitt, and Corey Bryant.

However, he has shown that he is still ruthless to a degree, as he left Schrader to be electrocuted in the Argent Arms International armory as payback for the fact that he had captured and tortured himself and the orphaned Werewolves Jiang, and Tierney.

Theo's newfound selflessness eventually led to a great development in his empathic side. He was initially unable to take Mason's pain after they were attacked by the Anuk-ite because, in Mason's words "You can't take pain if you don't care." However, Theo rose to the occasion and successfully took Gabe's pain in his final moments of life, even despite the fact that Gabe and the other Hunters in Monroe's Army were trying to kill them just seconds earlier.

At the end of the series, Theo is shown as one of two redeemed antagonists (along with Peter Hale) who had earned themselves positions as the McCall Pack's strongest allies, highlighting Theo's work to make up for what he's done wrong in the past.

Physical Appearance[]

Theo is a very attractive young man who has tan skin, green eyes, and light brown hair that he wears tousled with gel. He has also been seen with some stubble on occasion. He is on the shorter end of average height with a lean, athletic build; in fact, Malia Tate once stated that Theo had a "perfect body," and Theo seems to agree with this sentiment, since he has no problem stripping nude in front of others and claims he has nothing to hide. Theo is usually seen wearing trendy clothes, such as designer slim-fit jeans, solid-colored v-neck t-shirts, and hoodies, vests, or jackets in neutral colors.

Powers and Abilities[]

Evolved Chimera Physiology: As a Chimera, Theo possesses the common powers of an Omega-level Werewolf and Werecoyote, however at a somewhat lower level. Though he has been shown to be the strongest, as well as the most skilled with his powers of the ‘failed’ Chimeras, he was still inferior in strength to true werecreatures, as evidenced by Theo's comment that Chimeras are like "cheap knockoffs" of real shapeshifters. Notably, he was also the only Chimera who was able to shapeshift into a true Wolf, something that is rare even amongst true Werewolves. After Deucalion taught him how to take the powers of others, Theo gained additional abilities that were unique to those of packmates Josh Diaz and Tracy Stewart, which meant he briefly had the power to produce Kanima Venom, and control electromagnetic energy. As of Season 6, Theo has lost these extra abilities and has reverted to his "original" self. Initially Theo struggled to absorb someones pain for its traditional use, due to his lack of empathy, though he was able to successfully take Gabe's pain in the season finale.

Abilities[]

  • Advanced Combat Skills: Theo has shown himself to be a skilled fighter, making use of his Werewolf-Werecoyote instincts as well as his pseudo-supernatural abilities to great effect and what appears to be a degree of formal close quarters combat training. He was able to beat both Belasko and Josh, though he had initially taken them by surprise. His combat skills also allowed him to temporarily hold his own against the Dread Doctors, and survive multiple fights with the Ghost Riders..
  • Skilled Manipulator: Theo is shown to be extremely good at manipulation people, as he was able to fool and manipulate the McCall pack into believing he was a regular Werewolf who just wanted to join the pack for weeks. He was also able to manipulate the members of his own pack into doing what he wanted them to.

Weaknesses[]

Though Theo, as a Chimera, was not susceptible to mountain ash like true supernaturals are, the fact that his powers were likely inferior in strength to real shapeshifters still put him in a disadvantage in a fight. However, gaining more offensive powers such as Kanima Venom production and electromagnetokinesis has helped compensate for the lack of physical strength in comparison to Werewolves, Werecoyotes, and Kitsune. It is unknown if Theo is vulnerable to substances such as wolfsbane, mistletoe, or wolf lichen, which are commonly used to weaken Werewolves and Werecoyotes.

Relationships[]

Etymology[]

  • Theo: Theo is the short form of the masculine given name Theodore, which is derived from the Greek name Θεοδωρος (Theodoros), meaning "gift of God" or "divine gift." This is a combination of the Greek roots Θεος (theos), "god," and δωρον (doron), meaning "gift." It is a name notable for being shared by several saints, including Theodore of Amasea, Theodore of Tarsus, and Theodore of the Studite, along with also being the name of two popes. However, some names beginning with the prefix Theo- are not necessarily derived from Greek, but are rather derived from the Old Germanic theud, meaning "people or "folk." Such Germanic names include Theobald, Theodoric, and Thelonious.
  • Raeken: Raeken is a variant of the name Reagan, an Anglicized version of the Irish surname Ó Riagáin ("son of Riagán"), which is derived from the Irish personal name Riagán, which means "little king" or "little warrior." The name also is derived from the word riodhgach, meaning "impulsive," which, combined with the meanings "little king or warrior," is a very fitting surname for Theo Raeken considering his desire to be Alpha ("king"), his warrior instincts, and his impulsivity.

Trivia[]

  • Theo was the first Chimera and the only one to survive the Dread Doctors experimentation without rejecting his transformation like the others or needing to be resurrected with the green serum. However, though his transformation was successful, he was not truly a successful Chimera, as he was an unsuitable host for the Beast of Gevaudan, which was the Dread Doctors' ultimate goal.
  • Theo is the first and only person on the show who has successfully stolen the powers of creatures of a different species than himself, as evidenced when he killed Josh Diaz and stole his power of electromagnetokinesis, and when he killed Tracy Stewart and stole her ability to produce Kanima venom.
  • In Season 5A, Theo tries to corrupt the McCall Pack, especially Stiles Stilinski and Malia Tate, as he wanted to take control of the pack after Scott's death.
    • Theo encouraged Stiles to keep Donovan's death secret in order to gain Stiles' trust by bonding with him over having to kill in self-defense. It is likely that Theo sent Donovan after Stiles with the intention of forcing Stiles to kill Donovan so he could have something to use to manipulate him and turn him against Scott.
    • Theo also supported Malia in her desire to kill her mother, likely both out of genuine concern for Malia as well as to make her personality darker to increase the chances that she would be in his pack.
  • Theo is drawn to Malia due to her being a Werecoyote, suggesting that Werecoyotes can subconsciously feel a kinship with one another.
    • It is possible that Theo is drawn to Malia because of a subconscious need for a coyote mate or pack.
  • Theo has the unique ability to shapeshift into a full wolf, a power that no other part-Werewolf Chimera is known to possess.
  • After failing to have Liam kill Scott so he could kill Liam and take Scott's Alpha power, Theo turned his sights on taking the Beast of Gevaudan's power, though he was ultimately unsuccessful in this task as well.
  • Cody Christian has stated Theo wants to became a real Werewolf, which was further confirmed by Theo's comments in the show, which made it obvious that he has an inferiority complex about being a Chimera and not a true shapeshifter.
  • According to Teen Wolf creator, Jeff Davis, everyone loved working with Cody Christian, which is why they left his fate uncertain rather than killing him off, allowing him to return in Season 6.
  • The same wolf that was used to represent Derek Hale's full-wolf form was also used to represent Theo's full-wolf form.
  • Theo has had two conflicting birthdates revealed; 04/15/1998 & 11/23/1998. The first was seen in Parasomnia on his Beacon Hills High School transfer form, while the second was shown on an arrest form from a behind the scenes photo from season 6A shared by Cody Christian.
    • His birth year being listed as 1998 on both forms is, assumably, an oversight by the writers as given the timeline established by the show that would make him only 14/15 years old in seasons 5 & 6.
    • If his birthday is indeed November 23, he shares his birthday with both Claudia Stilinski & Meredith Walker (the latter of whom also had her birthdate listed as being in 1998, another presumed error).

  1. ↑ In "Parasomnia", his birthdate is given as 04/15/1998 on his transfer form to Beacon Hills High School. This is a timeline error as he would be born between 1994 and 1995 as he is in the same year group as Scott and Stiles. In "Pressure Test", Theo is seen signing a release form, however, the information on the form is unreadable and blurred. Cody Christian posted a photo of the form on Twitter, which showed his birthdate as 11/23/1998. This, again, is a timeline error and should be November 23rd, 1994.
