As of the end of Season Three, major changes happen to the cast that affect the entire continuity of the show; spoilers will be unmarked. YOU HAVE BEEN WARNED. Beware: only developments of the newest season will be spoilered. (Right now, that's Season 5.)
General Werewolf Tropes
- Absurdly Sharp Blade: Werewolf claws are closer to knives than to animal claws or human fingernails.
- Audible Sharpness: The claws also have their own sound effect when extended.
- Aura Vision: For a Kitsune, their Fox spirit is present as an aura, which they have to learn to hide. Werewolves can see it when using their wolf eyes.
- Ax-Crazy: When under the influence of the full moon they start rampaging and will kill anyone in their way. Also during the bitten stage of a new werewolf.
- Bad Black Barf: This shows up for a few reasons. For one, it is a side-effect of poisoning, usually by wolf's bane, but other agents such as mistletoe and Kanima venom cause this as well (as seen with Cora and Erica). While werewolves possess a powerful Healing Factor, their bodies can't properly heal from poisons and results in weakening of their bodies and blackened blood. Another cause of these symptom can actually come from the bite of an Alpha werewolf. While most people can be turned into new werewolves via an Alpha's Bite, others suffer an extreme rejection to it, leading to death.
- The Berserker: All new werewolves are like this initially, especially during the full moon. It does lessen later on, either through experience, or pure focus by holding onto an "anchor" - usually a feeling or a person - or by reciting a meaningful mantra until the rage passes.
- Blue-and-Orange Morality: Played with. Werewolves are in some ways quite different from humans: they live in packs with specific hierarchies and structures, they spend part of their lives as a human-wolf hybrid or a full animal, and their physical abilities and health are beyond those of average humans. As a consequence, a lot of their interactions come off as very rough and overly violent to humans and Bitten werewolves unfamiliar with werewolf norms. It's made a point of characterization for several characters, especially Derek.
- Brought Down to Normal: During the lunar eclipse, werewolves lose all their supernatural powers and abilities, they are rendered completely human.
- The Chosen One: Becoming an Alpha usually works in two ways: inheriting an Alpha's power when they die, and plain murder. It's hinted a dominant establishing his leadership over a number of others works as well. However, there is another, extremely rare option: becoming an Alpha purely by power of character. This is called a True Alpha, and unsurprisingly, protagonist Scott McCall is one.
- Curse That Cures: One of the perks of turning into a werewolf is the healing factor taking care of injuries and diseases: Scott loses his asthma, Erica loses her epilepsy, and Liam heals a broken leg. This seems to work for physical ailments only.
- Also in that the Bite can exorcise a Nogitsune from the host's body.
- The Empath: Played with in an interesting way. Werewolves are by no means psychic, but can detect emotions such as anger, arousal, frustration and even disgust. Derek reveals that this is due to their sense of smell; by picking up on hormonal changes in a body through chemo-signals, a werewolf can tell what state of mind a person is in, even in places where the person has been before.
- Energy Absorption: When Alphas kill their own pack members, they absorb the power of the victim.
- Evil-Detecting Dog: As apex predators, werewolves scare regular animals. Both wild animals and pets react either aggressively or fearfully when a werewolf is near, even when they are fully human. In the Pilot, we see deer stampede away from the Alpha, clinic animals bark and hiss at Scott during his first few days after being bitten, and a dog growling at Derek at a party. It's implied that werewolves can conceal (or use) their animal natures to overcome this effect: Scott is seen glowing his eyes at a dog who then becomes submissive and friendly to him in the first episode, and is not shown to have serious difficulties maintaining his job at the Animal Clinic (even before Deaton reveals he's a lot more knowledgeable about the supernatural than he lets on).
- Exposition Beam: A werewolf can share memories by planting the claws into the back of a recipient's neck. Peter projected his memories of his time in the hospital to Scott this way, while Derek accidentally transferred memories of the Hale House fire to Jackson. Lydia, a banshee is able to hear and translate the recollections embedded in Talia Hale's claws.
- Good Thing You Can Heal: With a number of exceptions, werewolf characters will have to make use of their healing powers - they'll be attacked by other supernatural beings or hunters, get electrified, shot at, poisoned, set on fire, stabbed, bitten, clawed, and even get their limbs cut off. Beacon Hills is a dangerous place to be a monster.
- Hair-Trigger Temper: Werewolves all have great difficulty controlling their anger, learning to keep their emotions in check is one of the most important skills for new werewolves (and some other shapeshifters) to master, both for resisting involuntary changes and making voluntary ones.
- Healing Factor: All werewolves heal quite quickly, though various, usually supernatural means - from an Alpha's claws, to demonic swords to various species of wolfsbane/aconite - can make the process more complicated.
- Healing Hands: Werewolves can absorb physical pain from other beings, which is used as a plot point and a way to illustrate character motivations several times.
- Hot-Blooded: If a werewolf starts to suppress their Hair-Trigger Temper you can expect them to be very hot headed and passionate. Also in this state they are more in control of their rage.
- Icy Blue Eyes: Betas and omegas gain these when they have kill someone innocent.
- Klingon Promotion: One of the ways of becoming an Alpha werewolf is to kill an Alpha. Derek, Peter, and twins Ethan and Aiden have all employed this.
- Kryptonite Factor: Electricity. Werewolves (and most shapeshifters) react to electric shocks not unlike humans do. Certain levels of current can even keep them from shifting, or deprive them of other abilities like their Healing Factor. Chris Argent, at one point, states that he's begun to wonder exactly how his family obtained such scientifically-precise data on the effects of electricity on werewolves.
- Laser-Guided Amnesia: By using the same telepathic technique with their claws, werewolves can remove memories from the recipient as when Isaac had his memories removed from him by the Alpha Pack in the Season 3 opener, and when Talia removed Peter's memories of his fathering Malia Tate.
- Le Parkour: Since werewolves have superior agility, strength and speed, they are naturally a lot more athletic than the average human. Werewolf acrobatics are a staple of the show, with Derek, Scott, the twins, and now Liam being the main, but far from the only offenders.
- Living Lie Detector: Zigzagged. Thanks to their heightened sense of hearing, werewolves are usually able to distinguish whether someone is being dishonest or not by listening to subtle changes in heartbeats. However, this isn't fool-proof as several antagonists have distorted the truth and even flat out lied to werewolves without them being the wiser.
- Master of Your Domain: Werewolves can learn a mastery over their bodies that they can mask their own scent, preventing other shapeshifters from detecting them.
- Mental Fusion: Also by using their claws, they can meld minds with another person, thereby entering another person's subconscious or even have another accompany them as demonstrated when Scott takes himself and Lydia into Stiles' subconscious to separate him from the Nogitsune.
- Monster Lord: Alphas are this to other werewolves. Aside from being able to out-perform Betas in every way, they can also inflict longer-lasting wounds and even control the shifts of other werecreatures. The most defining trait of an Alpha is that they are the ones who can create more werewolves with a bite.
- My Sensors Indicate You Want to Tap That: Werewolves can smell a person's arousal or sexual attraction.
- Never Gets Drunk: Their rapid healing makes it impossible for werewolves and other were beings to get drunk, as Scott, Liam and Malia all had to learn to their disappointment.
- The Power of Friendship: Werewolves become stronger, faster and "better in every way" when they are part of a pack. Many of them seek out packs in order to survive and to defend themselves against enemies. Stated several times and used as a plot point throughout the show. Perhaps most notably, a wound Scott suffers near the end of Season 5A does not heal for most of Season 5B, but when he reassembles his pack, the very night he reclaims the last member (Lydia, breaking her out of Eichen House) the wound heals more-or-less instantly. Scott's Pack at this point in the series consists of him, Stiles (completely ordinary human), Lydia (Banshee), Malia (a Beta Werecoyote), Kira (Kitsune), and Liam (Scott's peronally-Bitten Beta and the only other actual werewolf in the Pack). This indicates that what constitutes a "Pack" is an extremely flexible definition.
- Puberty Superpower: Appears to be the case with born werewolves, as implied by Dr. Fenris. In flashbacks, we see teenage Derek having problems controlling his abilities and Peter teaching him how to temper himself. According to Peter, Talia did the same for Laura.
- Red Eyes, Take Warning: All the Alphas have these, signaling their greater strength and power over Betas and Omegas.
- Shapeshifting: All werewolves can shapeshift to differing degrees; from merely showing fangs, claws and reflective eyes, to a Wolf Man to a complete wolf form, which is usually only possible for Alphas, or very balanced Betas. There is also a monster form, which seems to require a certain instability shown by Peter Hale and Deucalion.
- Supernatural Gold Eyes: Beta or Omega Werewolves have these in their Wolf Man form; it's also a handy way to show they are supernatural, when they don't want to be too conspicuous. A Beta who has killed an innocent has electric blue eyes.
- Unstoppable Rage: Werewolves are very temperamental during their time of being bitten or during puberty and when angered usually go into this state especially when under the full moon.
- Vague Age: Werewolves seem to age at a slower rate, to the point where you can usually only guess how old they should be. A prime example is Satomi Ito who should be close to 130 years old yet only looks like she's in her sixties in the present. Born werewolves might be even more complex, as Peter looked like he was in his late teens/twenties in the time just before the Hale fire, just before assuming his current appearance, seemingly in his late 30s. Lampshaded by Stiles, in talking to Peter:Stiles: ... how old was (Derek)? How old were you? How old are you now?
- Wolf Man: During transformation, this form is usually taken on by Betas and Omegas, as well as some Alphas such as Scott.
- Working-Class Werewolves: The Hale werewolf family was well-established and respected prior to the events of the show, but after Peter kills the other members of the family, his nephew Derek and his pack operate out of the ruins of the Hale house. Derek himself is essentially homeless at first. On the other hand, other werewolves on the show, including titular teen wolf Scott, are implied to be middle and upper-class. Overall, the show portrays a mixed bag of ordinary people who just happen to be werewolves regardless of financial status.
The Hale Family
The Hales were a family of werewolves who saw themselves as the unofficial "protectors" of Beacon Hills. After most of them died in a fire six years prior to the series, their remaining members are siblings Derek, Laura, and Cora Hale, and their uncle Peter. In Season 3, Malia Tate is revealed to be Peter's biological daughter.
Peter Hale (portrayed by Ian Bohen & Michael Fjordbak)
Derek's uncle, the man responsible for Biting Scott, the original Alpha and the Big Bad of season one. Peter killed Derek's sister, Laura, his niece, in order to become the new Alpha of the Hale family. Originally faking disability, he later torments Scott, Derek, the Argents, and everyone else involved, until he is finally killed by Derek.
Peter then possesses Lydia later in Season 2 so to resurrect himself. Originally weakened, he bides his time and becomes an uneasy ally to Derek and the others after helping them against the Kanima. After Scott becomes a True Alpha and when his full strength returns in Season 4, he makes his move to have Scott killed, but when the plan fails, Peter faces off against Scott, taken down and incarcerated in Eichen House for his crimes. He comes back in season six not completely reformed but not trying to kill anyone either.
- And I Must Scream: He was aware, if not sane, for the six years it took him to heal from the fire. He also had some degree of awareness while he was "dead".
- Anti-Villain: Ultimately subverted, though he does seem to have hints of sympathy for Derek, Cora and Malia.
- Season Six shows the he does love Malia and three times was willing to take on Ghost Riders for her, the second time got him erased from existence again.
- Ax-Crazy: He's murderously unstable mostly during his time as the Beacon Hills Alpha, but even later his ranting about being the Alpha, the way he viciously murders the Mute, and his eventually revealed plans to murder Scott don't exactly make him seem mentally healthy at all.
- Back from the Dead: Manipulates Lydia from beyond the grave into orchestrating a ritual that returns life to his dead body.
- Big Bad: Of Season 1. Peter was the Alpha werewolf who was causing trouble and killing everyone in his path. He also killed his own niece, Laura, to become an Alpha, bit Scott and turned him into a werewolf, brainwashed and controlled Scott in the earlier days of his transformation, and wanted Scott to kill all of his friends through his control. He somewhat joins Kate in the role in Season 4.
- Big Bad Ensemble: With Kate in Season 1. Though, he becomes the biggest of the two bads and is the Final Boss.
- Big Brother Instinct: As a young adult he was very protective of Derek. Potentially subverted, since it appears he's usually the one who got Derek purposefully into trouble in the first place.
- Body Backup Drive: Implanted an imprint of himself in Lydia, just in case he died and needed someone to resurrect him.
- Deadpan Snarker: Peter has perfected the sarcastic remark to an art form, and uses it at every possible moment to mock those around him.Peter: It's quite a situation you've got yourself in here, Derek. I mean, I'm out of commission for a few weeks and suddenly there's lizard people, geriatric psychopaths, and you're cooking up werewolves out of every self-esteem deprived adolescent in town.
- Enemy Mine: He proves very helpful and willing to play for Team Good after resurrecting, handling Gerard and the threat of the Kanima with minimal loss of life.
- Evil Cannot Comprehend Good: Inverted. He knows about a hero's tendencies, he knows about the bonds of true friends, he knows the strength of sheer love. And he uses all that to control the situation and the people in it.
- Evil Former Friend: Subverted in that he claims he was Derek's best friend when the latter was in high school before, you know, killing Derek's sister and becoming one of the major antagonists.
- Evil Mentor: When they were younger, he had a habit of talking Derek into things that weren't morally sound and backfired badly. Such as convincing him that his human girlfriend would leave him if he didn't ask someone to turn her into a werewolf.
- Peter did regret that however, as his face clearly showed remorse and devastation when he found Derek with a dying Paige, Peter had genuinely thought he was doing Derek a favor.
- Evil Uncle: Peter is Derek, Laura, and Cora Hale's uncle. This didn't stop him from killing Laura in order to become an Alpha, though the circumstances of her death is debatable, Peter did lure Laura to beacon hills but whether he killed her intentionally is ambiguous, the memories he shows Scott supports his belief that he not in control.
- Faux Affably Evil: In contrast to his rude, good nephew, Peter is charming and quite pleasant, but entirely able to have a nice chat with you one minute and ram a pole into your torso the next.
- Gaslighting: Purposefully weakens Lydia psychologically so that she can bring him back from the dead.
- Handsome Lech: During a discussion that is a Crowning Moment of Funny Peter states in front of everybody that he thinks Scott's mom is gorgeous. Cue Scott looking disgusted and he (Scott) and Derek telling Peter to shut up.
- HeelFace Revolving Door: Goes from Big Bad to brainwashing Lydia into resurrecting him to actually being rather helpful to Derek and the others. Inverted, since he actually stays evil and is just biding his time to strike.
- As of season six the door is still spinning it seems as he is helping the pack again and even seems more willing to do the right thing i.e sacrificing himself to save Scott and Malia
- Hidden Villain: In a unique way. He's technically The Man Behind the Man to Meredith's Benefactor, since he convinced her the supernatural population of Beacon Hills needed a cull. However, he did this through accidentally projecting his insane inner rantings into her poor, unstable psychic's mind, while both of them were recuperating in a hospital, and he was lying in a coma.
- Large Ham: Both actor and character love chewing the scenery on occasion, especially when it comes to clarifying Peter's status:I AM the Alpha! I HAVE ALWAYS BEEN THE ALPHA!!!
- Lightning Bruiser: He generally avoids physical conflicts, but when he does fight, he proves to be a surprisingly capable foe.
- [[season six shows that while the pack could barely deal with one Ghost Rider, Peter was able to temporarily fight off two before being erased again, he fights three of them in episode 10, the finale of part A.
- Luke, You Are My Father: Finds out he has a child in Season 3. Played in an interesting way, since he originally knew about it, but got his memory magically altered by his sister.
- Manipulative Bastard: Probably the most manipulative in the whole series. Peter has wormed his way into becoming Derek's more or less trusted advisor and someone even the heroes go to for help by the beginning of Season 4. You'd think they would know better, after his run as the Big Bad of Season 1 and his psychological terror of Lydia in Season 2.
- Moral Pragmatist: He's somewhere between this and Pragmatic Villainy. He's more than willing to murder, manipulate and harm others to achieve his goals... until he loses his position as Alpha Werewolf and the Big Bads of season 2 and 3 effectively force him to ally with the heroes who brought him down and killed him; though he doesn't hold a grudge. While he's still the Token Evil Teammate, he's actually rather more prudent than bloodthirsty.
- Not So Different: His standard defense when someone brings up his many crimes is pointing out that others have also done extremely bad things for often worse reasons:Peter:[to Derek]: "You're the one that ripped my throat open".
- Papa Wolf: To Malia. In season 6, Peter is willing sacrificed himself for Malia
- Put on a Bus: Doesn't show up in Season 5, but was apparently still locked up in Eichen House. He gets mentioned a couple of times, too.
- Roaring Rampage of Revenge: He's more than little unhinged by the slaughter of his family.
- Tall, Dark, and Handsome: Ian Bohen (current Peter) is 5'10" and Michael Fjordbak (teen Peter) is 6'1"; Peter is also darkhaired and dangerously charming. Peter may be an evil bastard, but you can't deny he fits this trope.
- The Bus Came Back: Returned in season six.
- This Is Unforgivable!: In the Season 4 finale, he conspired with Kate Argent to have Scott killed by having him transformed into a Berserker then have him attack his friends so they would kill him. When Scott breaks free of the spell, he puts two and two together, furiously tells Peter he won't get another chance, and when they face off, Scott totally kicks his ass and he's incarcerated in Eichen House.
- Throwing Off the Disability: After the fire, he was left burned and comatose for six years while his cells slowly healed him. Pretends to be an unresponsive patient for a while as a coverup to his more sinister actions.
- Token Evil Team Mate: He may be on Team Good after his resurrection, but no one trusts him and no one doubts for a second that the man who killed his own niece for power is hiding under Helpful Uncle Peter. Turns out they are right at the end of Season 4.
- Took a Level in Badass: Peter was very powerful as an Alpha but his fighting style not very technical, season four he shows better fighting skills and [[spoiler:season six, he is very skilled at fighting, demonstrating excellent skill and was able to fight back two Ghost riders for a brief time and later three Ghost riders.
- Virtue Is Weakness: Is not afraid to state this regarding Scott being "so blandly moral" (see quote above). Also for his sister's leadership back in the day.
Cora Hale (portrayed by Adelaide Kane)
A young female werewolf first introduced in season 3 as one of the wolves kidnapped by the Alpha Pack along with Erica and Boyd. She's also Derek's younger sister, who had been presumed to have died in the fire.
- Action Girl: Her limited screentime still makes it clear that she is a very capable fighter.
- Big Brother Worship: Averted when she first shows up in Season 3A when she's disappointed by Derek's lack of competence, that she got "(her) ass thrown in a vault for three months for (him)". Though she does change her mind after she's healed by Derek's sacrificing his Alpha status to heal her, saving her life.Derek: You're okay.
Cora: I'm doing much better than you right now. (Smiles) And all because of you.
- Brutal Honesty: A trait she shares with her brother if the above quote is any indication.
- Broken Bird: The young lady lost her mother, her family, her Pack when she was eleven years old. Like Derek, it's not been good for her character. Later on in "Currents", she loses her friend Boyd, breaking down and crying on his corpse after he's killed by the Alphas and she even tries to avenge him by killing Aiden. She describes the feeling in her own words.Cora: It's not just revenge. Losing a member of your pack isn't like losing family. It's like you lose a limb.
- Deadpan Snarker: It runs in the family.
- Determinator: Even after the Alpha Pack kidnapped her and locked her in a bank vault for months, she still kept trying to make herself strong enough to fight them, to the point of doing intense physical training before she'd recovered from the ordeal and attacking Ennis when he, Kali, & Deucalion broke into Derek's loft.
- Distaff Counterpart: She is pretty much a younger, less broody Derek in a girl's body.
- Morality Pet: One of Dereks.
- Mysterious Past: We don't know what happened to her after she escaped the fire, other than that she lived in South America.
- Put on a Bus: She returns to South America after the events of Season 3A, due to Adelaide Kane gaining the lead role on Reign.
- Snark-to-Snark Combat: She has to tendency to do this with Stiles, much like her brother.
- Suspiciously Similar Substitute: To Erica: she inherited parts of her storyline, after Gage Golightly left the show between seasons.
Talia Hale (portrayed by Alicia Coppola)
Talia is the mother of Laura, Derek, Cora, and the older sister of Peter. Talia was the well-respected Alpha of the Hale pack. She was killed in the Hale Fire.
- Animorphism: Notable for being one of the very few Evolved werewolves, ones able to avert Wolf Man and shift into an actual wolf, an ability which made her a leader in the larger werewolf community.
- Big Good: Before her death, all of the nearby werewolf packs respected her wisdom and followed her lead.
- The Cameo: In Season 3B "Galvanize". Her spirit appears as her full wolf form to Derek when he utilizes a channelling ritual using her claws to meet with her and she tells him the purpose of the Hale Pack was to protect Beacon Hills.
- Death by Origin Story: Talia's death in the Hale Fire, for which Derek is indirectly responsible, set him on the path that he still follows.
- Good Parents: When she comforts her son in a flashback after he gave his girlfriend Paige a Mercy Kill from Ennis' Bite.
- Horrible Judge of Character: Averted as it's implied Talia was aware of her younger brother's unscrupulousness and duplicity, hence her actions of removing Peter's memories of the Nemeton's location (not just Derek's) to prevent him from possibly misusing it as well as those of his fathering a child with the Desert Wolf - an assassin.
- Ms. Fanservice: In her introductory episode. Briefly and justified as she's morphing from her full animal wolf form and covered up immediately for a meeting with delegations from other Packs.
- Posthumous Character: Talia only appears in flashbacks or in visions induced with her claws.
- Statuesque Stunner: The Hales have amazing genes.
Laura Hale (portrayed by Haley Roe Murphy)
Laura is Derek's older sister, and initially the only member of his family known to not be in the Hale Fire. Her death and dismemberment kick off the events of the series pilot.
- Animorphism: Laura, like her mother, had the talent to shapeshift to an actual animal wolf form.
- Half the Man He Used to Be: Cut in half by her murderer.
- Plot-Triggering Death: Laura's death and bisection provide the incentive Scott and Stiles need to get into the forest where Scott is bitten, kicking off his entire arc.
- Posthumous Character: Laura is only seen or seen speaking in flashbacks or memories inflicted on Scott by Peter Hale.
- This Means War!: When Derek finds the upper half of her body, he buries her outside the Hale House with a wolfsbane studded rope surrounding her grave in the shape of a spiral - a symbol which represents vendetta, revenge amongst werewolves making his intentions clear and he gets it later on.
The Alpha Pack
The pack of Alphas who appeared at the end of Season 2 and became major antagonists in Season 3A.
Deucalion (portrayed by Gideon Emery)
The mysterious blind leader of the Alpha pack.
- Asskicking Equals Authority: He is, without a doubt the strongest, most lethal in the Alpha Pack.
- The merged twins immediately become subservient towards him after they break rank in his presence.
- When Derek and Jennifer Blake (the Darach, who had singlehandedly swept the floor with Kali and the twins) face off against him simultaneously, he delivers a Curb-Stomp Battle to the two of them just being that much stronger and faster than them both.
- Badass Boast: It seems that being Alpha of Alphas comes with making some damn good speeches.Decualion: I'm a man with far more vision than simple murder. In fact... I'm here to show you just how much vision a blind man can have.
- Big Bad Wannabe: In Season 3A, he certainly starts out as being the biggest bad of them all but in the end Jennifer/the Darach ends up being the more formidable enemy and Deucalion becomes a reluctant ally to the Big Goods.
- The Chessmaster: Throughout Season 3A, Deucalion plays the protagonists, the Darach and his own Pack like a harp, he manipulates everyone, putting them all right where he wants them. He fools everyone into thinking he wants Derek to join his Pack when it's really Scott he wants.
- He covertly kills Ennis to entice Kali to come for Derek in retribution; in turn Derek would have to be forced to take the offer to join the Alphas and place he and Scott against each other.
- When the Darach comes to town, this only adds to his advantage when she abducts Melissa. Deucalion makes Scott the offer to help find her if he were to join his Pack, and then to save her, he'd force Scott to become a killer by killing Jennifer.
- Chewing the Scenery: To the point where he cracks the lenses of his sunglasses with his eyes during a speech.
- The Corrupter: He assembled a Pack of Alphas by first convincing them to kill all of their previous Packs to absorb all their power. It is straight said by Marin Morrell and Jennifer Blake that Deucalion turns people into killers, that he has them kill the ''people they love''.
- Deadpan Snarker: Not a-lot but he does have his moments of snark
- Defeat Means Friendship: He's the main antagonist of Season 3A, but after his defeat remains on friendly terms with Scott.
- Dropped a Bridge on Him: One would think that the guy who was capable of leading an Alpha pack without the fear of opposition, making a Merged Alpha completely submissive to his will, even CurbStomps both Derek and The Darach; would have easily sense and avoid a surprise attack made by a group of amateur hunters. It's especially jarring when in that same episode he was training both Scott and Malia on how to rely on your other senses and fight without your sense of sight.
- Evil Is Hammy: With his generally soft-spoken voice and charisma he certainly steals the scene while being evil at the same time.Melissa: You're him, aren't you.
Melissa: The bad guy.
Deucalion: You have no idea. (His eyes glow red)
- Evil Mentor: To Theo in Season 5B. Subverted, because he just pretends to tutor him, and is really working with Scott.
- Eye Scream: Had his eyes gouged out by Gerard, who jammed two flashbang arrows into them.
- HeelFace Revolving Door: Years before the series start, Deucalion was considered a reasonable and idealistic leader willing to work with others and seeking peaceful solutions to conflict - until Gerard betrayed him and the other werewolves willing to negotiate with the hunters, and he lost his eyes in the process. Killing one of his betas before he could usurp him made him aware he could amass power by murdering his pack and building a super-charged pack composed only of other Alphas.
- He briefly managed a HeelFace Turn at the end of Season 3a, after Derek and Scott convince Jennifer to heal him and let him leave, even paying Braeden to get Derek and Peter out of a tight spot.
- By Season 5, however, his eyesight has deteriorated again, and with it, seemingly, his sanity, causing another FaceHeel Turn. Except this time, it's just for subterfuge - Deucalion only became seemingly corrupted again to trick Theo into trusting him, only to work on undermining Theo and destroying his hold on the chimeras behind his back.
- Handicapped Badass: Hes functionally blind, and is still able to beat down Scott and Derek. Zigzagged in that while Deucalion is blind, he can actually see using his werewolf eyesight.
- Subverted after the Season 3A finale, because of Jennifer/the Darach restoring his eyesight.
- Zig-zagged in Season 5B, where the effects of Jennifer's healing seem to have revertef, with him casting blame towards Scott. This time, however, it's only pretend to make Theo believe he has really joined him against Scott.
- It Must Be Mine!: Deucalion wants the perfect Pack, one comprised only of Alphas. Finally, he wants the most unique of werewolves in his ranks, a True Alpha - Scott McCall.
- Manipulative Bastard:
- In Season 3A, he kills Ennis to gain more power after the latter was expected to survive his fight with Derek, and didnt tell Kali, Aiden, or Ethan about this. Naturally, the trio is now out for Dereks blood.
- In Season 5B, Theo has his chimeras kidnap Deucalion for information, and he is playing all of them like fiddles.
- The Mole: In Season 5B, he appears to mentor Theo to get back at Scott, but is really working with Scott to undermine Theo - an ironic reversal of Theo's role in 5a, where he did the same to Scott.
- Offing the Offspring: In a sense, given that he began advocating the murder of Betas after killing one of his own when said Beta tried to take the newly blind Deucalion out thinking hed have an advantage, thus increasing his power.
- Sinister Shades: Justified: he's blind - to a point.
- Soft-Spoken Sadist: Deucalion, head of the Alpha pack, speaks with a calm and soft cadence most of the time. The above quote is the exception.
- Start of Darkness: Deucalion used to want peace and an end to senseless killing before Gerard murdered several members of his pack unprovoked and blinded him. He was pushed further along, when one of his remaining betas tried to kill him, thinking he was helpless.
- Sword Cane: His white cane has a dagger hidden within it for when he needs to discipline his fellow Alphas.
- Team Killer: Apparently, the only way to join the Alpha pack is to slaughter all of your own betas and gain their power.
Kali (portrayed by Felisha Terrell)
Graceful and deadly, Kali stands as Deucalion's right hand within the Alpha Pack.
- Ambiguously Bi: She was involved with Ennis before his death. However, she relays to Deucalion when she'd attempted to kill Julia as part of forming the Alpha Pack she could have just left someone she loved die peacefully.
- Character Death: Gets killed by the Darach for mutilating and leaving her for dead when she was still Kali's Druid Emissary ... and possibly more.
- Dark Action Girl: Action enough to take down Derek and impale him with a rebar pipe, Dark enough to really enjoy it.
- Does Not Like Shoes: Has never been seen wearing footwear that would restrict her gnarly knife toes, even when disguised as a nurse.
- The Dragon: Kali is the only member of the Alpha pack shown to move even marginally contrary to Deucalion (i.e. telling him to hurry up with the speech) without being disciplined, implying a degree of authority typical of a second-in-command.
- Evil Feels Good: She straight up says the feeling of killing her own Pack members to absorb their own power is "liberating".
- Face Death with Dignity: She initially cowers but at the last minute screams: "I SHOULD HAVE RIPPED YOUR HEAD OFF!" when Jennifer uses telekinesis to raise and suspend glass shards and rocket them into her body, killing her.
- Faux Affably Evil: While pretending to be a nurse and sedating Isaac, Kali reveals that she's an Alpha during the equally unnecessary "count with me" sequence just as he passes out apparently purely to antagonize and agitate him.
- Femme Fatalons: Inverted. While Kali does have the standard issue werewolf fingernails, she makes combative use primarily of the nails on her feet.
- Kick Chick: Kali prioritizes attacks with her feet to make use of her razor sharp toenails.
- Love Makes You Evil: While she claims otherwise, Deucalion says her real reason in joining the pack was to be with Ennis.
- Team Killer: Kali was the lead Alpha of her Pack; she murdered every one of them subsuming their power in order to join the Alpha Pack.
- Terms of Endangerment: Refers to Cora as "little sister" in a deeply unsettling manner.
- The Smurfette Principle: She's the only female alpha of the pack.
Aiden and Ethan (portrayed by Max and Charlie Carver)
The twins, Ethan and Aiden, are first introduced chasing down Isaac like hounds after a fox. Members of the Alpha Pack, they quickly make a splash by enrolling at Beacon Hills High and setting their sights on Lydia and Danny in order to get to Scott.
In Season 3B, after the dissolution of the Alpha Pack they've lost their Alpha status and are now Omegas. Not wanting to be the lowest on the werewolf hierarchy, they now seek to redeem themselves to Scott and his allies.
- Arch-Enemy: The twins collectively become this to Isaac. Throughout their time in the Alpha pack, both of the twins have antagonized, injured and even helped kill some of the people Isaac felt closest to, not to mention causing him personal physical and psychological harm. Even after their HeelFace Turn, Isaac refuses to forgive either of them and vetoes them from joining Scott's pack. While Isaac is under the Nogitsune's influence, it almost leads to them being murdered by him.
- The Bus Came Back: Ethan along with Jackson returns to Beacon Hills to help Scott defeat Gerard.
- The Cameo: In the Flashforward opener of the Season 5 premiere, "Creatures of the Night", Aiden appears to Lydia saying she can't leave Eichen House yet. Turns out 'Aiden' is only Valack disguised as her former lover to emotionally distract her.
- Dark and Troubled Past: Before they joined Deucalion, Aiden and Ethan were the Omegas of their old pack, and thus treated quite badly. Turned Up to Eleven, both because as born werewolves, their pack members were likely their family - and to join the Alpha pack, they had to murder them.
- Death Equals Redemption: In the Season 3B finale, Aiden dies fighting the Oni. Despite Lydia telling him earlier he's a bad guy, she, along with everyone else, feels loss for his death.
- Fusion Dance: Aiden and Ethan can do this, melding together to form a more burly gigantic werewolf form. During Season 3B, Word of God has stated they have lost this talent in their feat to survive Jennifer Blake's killing their melded form.
- Go Seduce My Archnemesis: Their mission is to seduce Lydia and Danny in order to sabotage Scott. This doesn't go according to plan as they both eventually fall In Love with the Mark.
- HeelFace Door-Slam: They attempt to join Scott's pack, but he won't have them for their past misdeeds, although he's more willing to forgive Ethan than Aiden.
- Heroic Sacrifice: Aiden dies fighting the Oni.
- Love Redeems: While Ethan actually may have had some moral objections to being evil to begin with, Aiden wants to be a better man for Lydia.
- Magic Pants: Aiden and Ethan when they do their Fusion Dance to merge into the "Super-Alpha". The trope is played especially straight in that for some reason they remove their jackets and bare their torsos before merging, but their pants (and shoes) merge when their bodies do.
- Mr. Fanservice: No, no, you don't understand, they have to take off their shirts to merge into a great, big Alpha. Which they really do a lot.
- Morality Pet: Danny is one for Ethan: When Dannys around, Ethan is less antagonistic to Scott and his group, and is even helpful at times. Later, Lydia also proves to be one for Aiden, whose HeelFace Turn begins when she tells him she considers him a bad guy because he helped kill Boyd and she doesn't want to be with bad guys.
- Neck Snap: They meet this fate in their merged form courtesy of the Darach. Though they survive as individuals.
- New Transfer Student: Like most supernatural creatures who just up and enroll in a public school, it is unclear as to who exactly Aiden and Ethan's purported parent/guardian is. Deucalion is only barely of an age where he could pass as their father. The twins just show up on the first day of the school year and make their presence known.
- Older Than They Look: Being werewolves and members of the Alpha Pack, they're obviously older than they appear, since Aiden firmly stated they're not actual high school students, they're only working undercover so they should be out of their teens already.
- Put on a Bus: After Aiden's death, Ethan decides to leave Beacon Hills, ending his romance with Danny and sharing a goodbye kiss with him.
- Redemption Quest: Their role in Season 3B, after they lose their Alpha status and power after the Alpha Pack disbands, to redeem themselves to Scott particularly for Boyd's death and become Betas of his pack. They succeed though at the cost of Aiden's life.
- Sibling Yin-Yang: They work in tandem, but Ethan and Aiden are different in personality, with Ethan being more gentle and Aiden being more violent.
- Straight Gay: When the twins first show up, Lydia declares she "wants one" of them, clarifying "the straight one obviously." at Allison's query. It's the most overt hint we get at Ethan's orientation before he starts romancing Danny.
- Synchronization: Aside from the above-mentioned ability to combine forms, Aiden and Ethan can feel the other's pain from a distance. This shows up twice: first when Aiden is being attacked by Cora and Ethan clutches his chest knowing that his brother is in a fight. The second and final time we see this is when while Aiden is dying.Aiden: Does it hurt you as much as it hurts me?Ethan:(tearfully) Yeah.
- Red Oni, Blue Oni: Aiden (Red) is much more fiery, spontaneous, aggressive, and prone to violence, while Ethan (Blue) is more reserved, calculating, passive and friendly.
- Wounded Gazelle Gambit: The Twins draw Isaac out into the hallway, do a showdown at high noon style stand-off, and start throwing punches... at each other. Then, when the teacher and other students are just about to appear, one twin throws the other at Isaac's feet and vanishes, making him like the aggressor who doesn't have a scratch on him.
Ennis (portrayed by Brian Patrick Wade)
Ennis is the first of the Alpha Pack Scott encounters and sets the tone for the Alpha Pack's behaviour pretty succinctly: brutal and good at it.
- The Brute: Purely muscle, primarily tasked with hitting things and not possessing Kali's level of clout with Deucalion.
- Character Death: Deucalion takes him out to gain more power for himself.
- Dramatic Irony: Before the series time, Ennis launched a Roaring Rampage of Revenge against the Argent hunters for their killing a Beta of his Pack. Later on, he killed the rest of his Pack and his druid emissary to absorb their power.
- Flat Character: His main characteristics are brutality and a short temper.
- It's Personal: He tried to turn Derek's first love Paige in the most traumatic way possible. To make things worse, she didnt take the bite and died, prompting Dereks change from an goofy teenager into a brooding adult. Derek takes a particular dislike against him as a result.
- Jerkass: Hes been nothing but a pompous ass ever since his introduction.
- Smug Super: Lords his status over young Beta wolf Scott before getting out-Alpha'd by Derek.
- Team Killer: Shares this with Deucalion and Kali to join the Alpha Pack; killing his own Betas to absorb their power.
- Would Hurt a Child: Presumably, Peter or Derek asked him to bite Paige to turn her, but he's hardly gentle about it.
- You Have Outlived Your Usefulness: After Ennis is injured from his fight with Derek, not being able to heal himself, Deucalion kills him so to assimilate his power and to further his own plans for Derek and Scott.
Satomi's pack seems to consist mainly of non-combatant werewolves, who want nothing but live a relatively normal, quiet life without being bothered by anyone.
Satomi Ito (portrayed by Lily Mariye)
A beta werewolf and Noshiko's fellow prisoner at Camp Oak Creek in 1943 when we first meet her.
Between World War II and the present day she became an Alpha, the leader of a Pack which follows the principles of Buddhism to control their werewolf nature. Satomi was also a friend to Talia Hale.
- Cultured Badass: Taught herself to control her werewolf powers through playing Go. Over the years she then rose to Alpha status by adhering to the principles of Buddhism.
- Enemy Mine: With Chris Argent when Scott recruits him to help in protecting her pack from the assassins though she's known his previous prolific role as a hunter of werewolves before Scott assures her Chris is an ally of his.Chris: "I remember meeting you. But you weren't a Buddhist back then."Satomi: "And you weren't protecting werewolves. You were hunting them. - ..."Chris: '' ... "but (werewolves) you're still violent creatures.Satomi: "Aren't we all?"
- Fire-Forged Friends: With Noshiko, due to battling the Nogitsune in the 1940s. And in the present day, with Scott and his Pack while fighting off assassins for the Deadpool.
- Friendly Neighborhood Vampire: She and her pack just want to be left alone, and don't harm anybody.
- Killed Offscreen: In 6B, she attempts to negotiate with the fear-induced hunters chasing her pack. She gets killed for the trouble.
- The Mentor: To her pack, whom she teaches self-control through a Buddhist mantra, and to Derek, as well as somewhat to young Noshiko Yukimura back in the day.
- Older Is Better: She is the oldest werewolf seen, but greets Deaton with a playful sparring and takes out professional assassins with ease.
- Promoted to Parent: She took in Brett and his younger sister, Lori, after their birth parents were killed.
- Remember the New Guy?: Satomi is already acquainted with Deaton and Derek, having knew and visited his mother Talia before the Hale fire. Turns out she also met Chris Argent at some point before.
- Super Speed: When an assassin opens fire on her, she dodges the bullets Matrix-style while at the same time charging her attacker.
- Team Mom: To her pack, being actively supportive and protective of them.
- Warrior Poet: Her Buddhist beliefs and philosophical outlook helped her master werewolf rage and develop techniques to avoid discovery.
- Weapon of Choice: An emei dagger.
Brett Talbot (portrayed by Cody Saintgnue)
A young Beta in Satomi's Pack and rival Lacrosse player from Liam's former school. He initially does not like Liam overly much, but after Scott and his allies help Satomi and her pack against rogue hunters, he slowly becomes friendlier, and even helps Liam out on occasion.
- Back for the Dead: He and Lori come back in two episodes of 6B. In the back half, Brett is poisoned by Monroe, and they're both hit by a car and killed, despite Liam's best attempts to save them.
- Big Brother Instinct: Protects his younger sister Lori from rogue hunters by putting himself physically between her and their arrows.
- I Owe You My Life: Brett helps Liam during the lacrosse game because Scott saved his life and Liam is Scott's Beta. From then on, Brett is practically a solid ally to Scott, Liam and their Pack.
- Jerk Jock: He is this mostly to Liam, but in general he behaves quite cocky and arrogant on and around the field. However -
- Jerk with a Heart of Gold: After being saved from assassins by Scott and Stiles, he starts respecting Scott and his pack, even offering Liam advice when he has trouble adjusting.
- Meaningful Name: His last name, Talbot, is a reference to Lawrence Talbot, the original Wolf Man.
- Mr. Fanservice: He likes changing shirts while on the field, or playing shirtless from the start. Mason certainly appreciates it, as does a large part of the audience.
- One Head Taller: Brett is 6'2", and has at least a 1/2 ft on the other characters, if not more.
- The Rival: to Liam, in general, and relating to Lacrosse in particular. They get along better over time, though.
- Tall, Dark, and Handsome: While Brett isn't dark-haired/skinned, he is most certainly tall (as stated above, 6'2") and handsome.
- ¡Three Amigos!: Starting to become this with Liam and Mason in Season 5.
Lori Talbot (portrayed by Lily Bleu Andrew)
Brett's younger sister, and another werewolf in Satomi's pack.
- Action Survivor: In Season 4, when her Pack are under attack from assassins, rogue hunters during the Deadpool, Lori is not a fighter because of her age. Later though ...
- Action Girl: In Season 5, Lori's now every bit as capable in a fight as Brett is, possibly even more given how she goes toe-to-toe with Kira's kitsune form.
- Back for the Dead: As mentioned above, she and Brett are killed by a bunch of rabid hunters.
- The Bus Came Back: After having not been seen since Season 4, Lori reappears at her brother's behest to help Scott's Pack find the identity of the Beast of Gevaudan.
- Deadpan Snarker: After watching Possessed!Kira fling Scott across a hallway, she just dryly asks, "...a friend of yours?"
- Dual Wielding: Lori gets a lacrosse stick she was using to defend herself with chopped in half, so she improvises and starts fighting Eskrima-style with both pieces.
- Happily Adopted: Lori and Brett were taken in by Satomi after their birth parents died.
- Nice Girl: To a fault: her concern and kindness over Kira's possession nearly gets her killed for her trouble.
Kincaid (portrayed by Geno Segers)
A werewolf who is the main bodyguard of the Japanese mobster Katashi.
- The Brute: Kincaid is a werewolf - a big one. The perfect choice for the lead bodyguard of a paranoid Japanese mobster like Katashi.
- Curb-Stomp Battle: He delivers a whooping of a beat-down to Scott, Allison and Kira. And that's after he knocked out Deputy Parrish and his colleague.
- On the other hand he himself is delivered a No-Holds-Barred Beatdown from Ethan and Aiden.
- Dramatic Irony: When Isaac is posing as a arms dealer with Kincaid over a particular gun, he's told a story of a duel between the brothers that originally owned the gun, but Kincaid tells the younger werewolf that was the cover story. The gun was instead used as an execution of one brother by the other because the victim was bitten by something monstrous. Kincaid has his claws unsheathed throughout the entire interview.
- Only in It for the Money: Apparently the reason Kincaid is in Katashi's service. Also, when Scott's Pack demands the Shugendo scroll, he tells them the scroll itself is worth three million.
- Smug Super: He scoffs at Scott's Pack when they demand the Shugendo scroll from him. He's got reason, too, since he towers over them at 6'4".
Sebastien Valet/La Bête du Gévaudan/The Beast (portrayed by Gilles Marini)
The original werewolf who became known as the Beast of Gévaudan, Sebastien Valet murdered scores of people before he was hunted down and killed by his own sister, Marie-Jeanne Valet, who became the first werewolf hunter of the Argent family line.

- Evil Makes You Monstrous: Word of God says Sebastien was born a bona fide psychopath and that this plays a part in his demonic werewolf transformation.
- Faux Affably Evil: Sebastien is soft-spoken and charmingly polite - unless you stand in his way. Or you don't stand in his way, but he wants to murder you, anyway. Or you are a contemporary teenager, whom he finds annoying and way too confident.
