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.
General Werewolf Tropes
Several tropes apply to all werewolf characters, or all werewolves of a specific status, due to unified rules for how werewolves work
. Don't list these tropes on the werewolf characters themselves unless there is a noteworthy example of how that character doesn't act quite like the rest or has the trope used in a particularly interesting way.
Scott McCall (portrayed by Tyler Posey)
"I usually have no idea what I'm doing. Actually, I always have no idea what I'm doing."
Scott is the protagonist and main character of the series. Originally, Scott is an unpopular, loner, social outcast, teenage human high school student. He was an asthmatic, a mediocre athlete or lacrosse player at his high school and he had a difficult time with girls and attracting the opposite sex. Personality wise, Scott is socially awkward, a loner and clumsy. Scott's life and destiny changes forever when he is unexpectedly bitten by a large, strange animal in the woods one evening. This animal, unfortunately, is an Alpha werewolf. Now, Scott must balance his newfound powers and abilities as a werewolf with the normal life of a human teenager.
Allison Argent (portrayed by Crystal Reed)
"We're just a bunch of teenagers. We can't handle this."
Allison is the beautiful, new girl in Beacon Hills. She's been sheltered from her family's double life as a clan of werewolf hunters. She begins to fall for Scott; the feeling is mutual. However, her lineage might complicate matters some and make her relationship with Scott tension-packed.
- Action Girl: Once she gets combat training from her father, Allison is a strong, capable fighter who can hold her own in fights against werewolves and oni.
- Action Girlfriend: She may be the love interest of The Hero, Scott, but she's more than just the love interest or girlfriend. She is also an action girl and a capable fighter at heart who can stand up for herself.
- Action Survivor: Before she embraces the Argent legacy of being a werewolf hunter, Allison is ill-equipped to deal with the hunter/werewolf conflict her family and boyfriend are in.
- Alliterative Name: Both Allison's first and last name begin with the same a sound.
- Anchored Ship: After Scott and Allison break up due to their conflicting loyalties, their relationship remains on hold even though their feelings do not. They both start dating other people - and then Allison dies.
- Archer Archetype: Allison is eternally practical, best demonstrated in Season 3 when she breaks into an abandoned bank while the boys are talking about breaking into the bank and corrals Cora and Boyd more efficiently than even her father, and independent (mostly due to an internalized fear of being weak). She also shoots things with arrows.
- Beast and Beauty: Scott is the Beast (a werewolf) and Allison is the Beauty (a beautiful human girl in love with him).
- Deuteragonist: While the main plot follows Scott trying to learn how to be a better werewolf, there is a parallel plot about Allison learning to become a better hunter. The two plots naturally intersect due to shared high school drama and the occasional pressing need to save Beacon Hills.
- Died in Your Arms Tonight: She eventually bleeds out in Scott's arms, much to his chagrin.
- The Dragon: After her mother is Driven to Suicide, Allison steps up to lead the hunters, but is really just a pawn of her grandfather, Gerard,. Though she's nominally the leader, the relative balance of combat prowess to scheming makes her the enforcer of Gerard's will.
- Evil Costume Switch: When she begins working with her evil grandfather in Season 2, she starts wearing all-black. She gets better (and her wardrobe gets brighter) in season 3.
- Face-Heel Turn: Allison has a tendency to be recruited by less scrupulous members of her family to be part of their evil, anti-werewolf schemes.
- Near the end of Season 1, her aunt Kate recruits her as a sidekick to help deal with the Alpha. Allison's discomfort with Kate's methods stop the turn from sticking.
- In Season 2, when her mother, Victoria, is Driven to Suicide, Allison's grandfather, Gerard, pushes her to lead the hunters in a werewolf purge. Unlike the first time, Allison's heart is in it, which leads to her trying to kill Erica and Boyd.
- Fallen Hero: In Season 2, the Cynicism Catalyst of the death of her mother kicks Allison towards being a fanatical hunter, out to kill Derek's pack.
- Girl Next Door: In Season 1, Allison is the pretty, kind, sweet girl who is easy to befriend, in contrast to the more socially conscious Lydia.
- He Who Fights Monsters: In Season 2, the death of her mother, Victoria, in a werewolf-transformation-preventing suicide turns Allison into a werewolf hunter whose main mission and goal is to hunt and kill as many werewolves as possible, becoming just as out of control as the creatures she was hunting.
- Heel-Face Revolving Door: In the first two seasons, Allison is pulled between her (mostly) innocent friends and her (mostly) ruthless family. She's usually trying to keep someone alive and safe - Derek's pack members being a bit of an exception after he inadvertedly bit her mother, leading to her suicide.
- Heel-Face Turn: Though Allison twice joins evil family members to kill werewolves, she never sticks around once she realizes just how far they're willing to go.
- Heroic BSOD
- When Kate reveals the existence of werewolves in Season 1, Allison almost completely shuts down.
- In Season 2, the death of her mother triggers another breakdown.
- Hidden Depths: Allison is surprisingly skilled in gymnastics and archery and is willing to live a little wilder than her good-girl-persona originally suggests. Secretly frustrated by her "weakness," she tries to harden herself in the face of tragedy, but almost becomes as "monstrous" as the werewolves themselves; it's only when she manages to reconcile her protective instincts and her empathy that she becomes master of her own actions instead of a pawn of her less than savoury relatives.
- Impaled with Extreme Prejudice: Speared by an Oni in the penultimate episode of Season 3, leading to her death.
- In the Blood: Allison is the latest in a line of werewolf hunters descended from one of the first recorded werewolf hunters, in medieval France.
- Killed Mid-Sentence: "You have to tell my dad! You have to tell him — *cue Dead Hand Shot*
- The Masquerade Will Kill Your Dating Life: Once Allison starts her training as a werewolf hunter, Scott and Allison find themselves on opposite sides of The Masquerade. This twice comes between them: when Allison first discovers Scott is one of the werewolves her family is hunting and when Allison's mother gets bitten, causing Allison to be a lot less sympathetic to werewolves in general.
- New Transfer Student: Moves to Beacon Hills in the pilot, walks into class and is introduced with the classic "Class, we have a new student today" speech from every anime ever.
- Nice Girl: She is always friendly and sweet, in contrast to Lydia, who especially at first fills more of an Alpha Bitch role. After her mom dies, this sweetness temporarily disappears.
- Only Friend: The show is on a miniature budget, so Nice Girl Allison and popularity queen Lydia appear to be each other's only friends.
- Ordinary High-School Student: Before her family legacy as hunters is revealed to her, Allison is the everyday high school girl.
- Single Woman Seeks Good Man: She promised herself that she wouldn't get involved with a boyfriend because she was looking for a nice, decent guy. Enter Scott McCall.
- Star-Crossed Lovers: Allison and Scott. He's a werewolf; she's a werewolf hunter.
- Unwitting Pawn: Her grandfather Gerard shamelessly uses her grief for her mother's death for his own gain.
Stiles Stilinski (portrayed by Dylan O'Brien)
"I'm 147 pounds of pale skin and fragile bone. Sarcasm is my only defense."
Stiles is Scott's best (and at first, only) friend. Initially, he's the only one who Scott trusts to tell about his transformation; this is a good call on his part, given that Stiles goes very
out of his way to help his buddy out.
In the third season, he ends up possessed by a malevolent spirit of Japanese origin called the nogitsune. Due to this, he is forced to fight his friends and family against his will until they find a way to save him.
- Action Survivor: As an untrained human among hunters, werewolves, and worse, Stiles should reasonably be monster chow. Instead, through wits and pluck, he manages to not only stay alive, but often play a crucial part in the heroes' success.
- Adorkable: Stiles is quite awkward and can politely be described best as "offbeat", but manages to be endearing and amusing throughout.
- Afraid of Needles: Stiles passes out at the sight of needles, as evidenced when he saw Scott getting a tattoo.
- Alliterative Name: Stiles' first and last name both start with the same sound and the same letter: S. This is no coincidence, as his apparent first name is actually his nickname.
- Always Someone Better: Feels this way in regards to both Scott and Jackson. For Scott it's the fact that Scott has all the cool werewolf powers. For Jackson it's that Jackson is first in Lydia's heart.
- Ambiguously Bi: While Stiles has harbored a long-term crush on Lydia and is clearly attracted to Malia, he is also very interested in whether or not he's attractive to gay guys, and asks both Scott and Danny whether they find him attractive. After his dad finds him at a gay bar, he tells his dad that he "could be [gay]." Additionally he seems almost disappointed when Danny's offer to sleep with him turns out to be a joke, and takes serious pause when Caitlin asks him if he's into guys.
- Attention Deficit... Ooh, Shiny!: Averted. Stiles has ADHD according to Word of God, but it mainly manifests in impulsive decisions and body language.
- Badass Bookworm: Stiles has an exceptional mind for research, having gleaned the essentials of werewolf existence from the Internet and observing Scott, and was able to train Scott to control himself more efficiently than Derek (though Derek being a born werewolf doesn't exclude him from being a singularly terrible teacher). As for Badass, he stands up to Derek on more than one occasion, Chris Argent at least once, and ran into battle against a fully-wolf Peter and threw a Molotov cocktail at him despite sarcasm "being [his] only defense".
- Brains and Brawn: Stiles is the Brains to Scott's werewolf Brawn.
- Character Development:
Coach Finstock: For his final question for his mid-term exam, he detailed the entire history of the male circumcision.
Sheriff Stilinski: Well...I mean...it does have...historical significance, right? I mean...
Coach Finstock: I teach economics.
- The Conscience: Stiles often helps Scott to keep a hold onto his humanity and has helped him with his lycanthropy, especially after he is bitten and turned.
- The Confidant:
- Whenever Scott needs someone to talk to, Stiles is there for him.
- Stiles and Lydia bonding at the school dance near the end of Season 1 leads to her trying to open up to him in Season 2. Unfortunately for their relationship, Stiles leaves her hanging to deal with Kanima-related matters of life and death.
- Cool Loser: Just like best — and initially only — friend Scott, although more understandable in his case.
- A Date with Rosie Palms: Stiles makes reference to this on occasion, which is fairly comical considering he's a confirmed aversion of A Man Is Not a Virgin.
Stiles: I'm playing? On the field? With the team?
Finstock: Yes, unless you'd rather...play with yourself.
Stiles: I already did that today, twice.
- Deadpan Snarker
- Demonic Possession: When the Nogitsune takes hold of him, it's not pretty.
- Determinator: Once Stiles has a mission, he never gives up. Two instances stand out:
- When the Kanima paralyzes Derek and then traps them in a lap pool, Stiles keeps the much heavier Derek and himself above water for over two hours without any assistance.
- Stiles makes his way across the sheriff station - which is, at the time, a battleground between the Argents, the Kanima, and the werewolves - crawling on the ground, on his belly, with the majority of his body still paralyzed from the Kanima's venom, in order to reach and/or rescue his father.
- Did You Just Flip Off Cthulhu?: Stiles has a habit of mouthing off at insanely powerful creatures who already don't like him.
- Distressed Dude: Although Stiles is a very capable sidekick, sometimes he needs quite a bit of saving too. At least once a season, a major villain will kidnap him to get at Scott.
- Dogged Nice Guy: Stiles has spent nearly a decade obsessed with Lydia, while she remained blissfully unaware of his existence. Eventually, they develop a true friendship, with Stiles apparently growing out of his crush.
- Dope Slap: Stiles gives one to Scott when Scott says he might go to Derek for help about being a werewolf.
- Dream Within a Dream: Stiles starts getting these after sacrificing himself in the season 3A finale. What's worse is that he's hallucinating usual ways you can tell that you're dreaming (unable to read, people having too many fingers) in real life, so even when he's not dreaming he thinks he could be.
- Enter Stage Window: His common entry into the McCall residence is through Scott's window... before he has a key made.
- Evil Feels Good: Stiles tells Malia in "The Benefactor" that the worst thing about being possessed by the nogitsune was that he enjoyed every moment of it even while he was hurting everyone he loved.
- A Friend in Need: He sticks by Scott even after Scott nearly kills him during a werewolf transformation.
- Genius Ditz: Despite his serious troubles with ADHD, including writing an essay on circumcision on his economics midterm, he has near perfect grades, is an amazing researcher and investigator, and he and Lydia are probably tied for the smartest characters on the show.
- Genre Savvy: Stiles is much more aware than Scott of the rules governing werewolves and chides him for not recognizing wolfsbane. He also is more focused on the werewolf plot than Scott much of the time - Scott is often a little distracted. He also, noticing that Scott is showing signs of being a werewolf, proceeds to read what seems to be every book in the library and EVERY POSSIBLE WEB PAGE on werewolves. Derek mocks this when he talks to Scott in the second episode.
- Heterosexual Life-Partners: Scott and Stiles are inseparable and have been through everything together, good and bad. They often go through withdrawals if they are separated for too long, to the point that the worst punishment Scott's mom can think of for him is banning him from spending time with Stiles.
- Hollywood Nerd: Stiles is intelligent and socially inept, but also attractive and quite charming.
- Hyper Competent Sidekick: Scott is more brave than bright, and relies heavily on Stiles to do the thinking. With his ADHD and general geekiness, it would seem like he should be a comic relief character, but Stiles' intelligence and bravery makes him indispensable to the usually clueless Scott. In fact, Stiles is so useful that Scott has to share him with Derek on the sidekick front.
- I Just Shot Marvin in the Face: Stiles fiddles with Allison's crossbow and narrowly averts shooting Scott's thanks to his Super Reflexes as a werewolf.
- Inferiority Superiority Complex: It becomes clearer and clearer that his ruthlessness in pointing out others' faults is largely due to him feeling inadequate himself.
- Last Name Basis: 'Stiles' Stilinski is only Stiles. Even his father calls him Stiles.
- Missing Mom: Claudia Stilinski died of frontotemporal dementia when Stiles was nine years old. He blames himself for her death, if his hallucination of his father in Season 2 is anything to go by.
- Motor Mouth: Once Stiles gets started on a tangent, there's practically no stopping him unless Derek's around to glare at or threaten him - and not even that's guaranteed to work all the time.
- Muggle Best Friend: To Scott. Aside from his brain and knowledge of supernatural lore, Stiles is utterly human. He also has no combat training, unlike Allison.
- Nerds Are Virgins: Geeky Stiles is explicitly a virgin as of season 3, although he loses it later on.
- Nightmare Fetishist: The series is set in motion by Stiles wanting to go into the woods to see a dead body. He delights in the fact that the police only find half of her. His reaction to Derek almost dying of wolfsbane poisoning, only to writhe around and then pass out from the cure, is a hearty "That was AWESOME!"
- No Social Skills: A mild version. Although Stiles is no where near anti-social, he is extremely socially awkward around people in general and doesn't seem to be overly comfortable around a larger group of people. In fact, Stiles seems to prefer the company of a few select group of people such as Scott, Lydia and Allison.
- Not Now, Kiddo: In "Night School", while the rest of the group are barricading the door from the Alpha, Stiles is trying to point out the 20-foot windows.
- Not What It Looks Like: Fortunately, most of the persons who walk in on Stiles performing something dubious are wise enough to not ask.
- Only Friend: Stiles seemed to be the only person whom Scott hung out with before he was bitten, considering that Scott was a loner and a social outcast.
- Only Known by Their Nickname: His first name is apparently enough to reduce Coach Finstock to giggles and claim that such a name should "amount to child abuse". It's apparently very difficult to pronounce. It's also difficult to even spell, as a doctor looking at his chart isn't sure whether it's correct or not. Even his father calls him "Stiles."
- Only Sane Man: Served as the "Maybe you should avoid situations where you'll kill people" voice of reason throughout Season 1 in contrast to Scott's "Allison! Allison!"
- Open Mouth, Insert Foot: Due to Stiles Motor Mouth, Stiles has a habit of saying the wrong thing at the wrong time, leading to lots of awkwardness.
- Oral Fixation Fixation: He has a tendency to chew on stuff, including lacrosse gloves, overabundances of curly fries, and an underused highlighter cap, to name a few of the victims.
- Overshadowed by Awesome: By the end of Season 2, Stiles knows that he's the most vulnerable of the group, being the only one without combat training or some form of supernatural power.
- Plucky Comic Relief: Stiles is the comic relief of the show, always having an appropriate quip for Scott's situation, mouthing off to the villains, and getting awkwardly flustered around Derek.
- Pragmatic Hero: Stiles is probably one of the most logical and pragmatic characters on the show. Comes with being a Badass Bookworm and the brainiac of the core group.
- Reality Ensues: Stiles always gets up to some serious shenanigans like stealing police property and kidnapping one of his fellow students... which then causes his dad, the town Sheriff, to lose his job.
- The Reliable One: Stiles is the Hyper Competent Sidekick to both Scott and Derek, as well as being strongly committed to protecting virtually everybody, even enemies such as Ethan.
- Subverted in the Season 2 finale, where he refuses to help Lydia save Jackson because it would get Jackson out of the way and expose Lydia to greater danger. It's actually a Double Subversion, since when the chips are down, Stiles can't help but do the right thing.
- In the episode "Motel California", Stiles enters a big puddle of gasoline, to stop Scott, who is drugged and holding a lit flare, from committing a fiery suicide even though odds were good that he would be burned to death if he failed to get the flare away from the super-strong Scott.
- Secret Keeper: In the beginning, Stiles is the first and only non-werewolf to know that Scott is a werewolf who is cursed with lycanthropy.
- Shipper on Deck: In the beginning, Stiles is a Scott/Allison shipper.
- Sidekick: Stiles usually assists or helps Scott during a mission, plan or battle, and often refers to being the Robin to Scott's Batman.
- The Smart Guy: Of Scott's initial group of friends and allies, Stiles is the only one who bothers to think things through and research Scott's condition. He even specifically refers to himself as the smart one. Later, he tends to share the role in the group with Lydia though, as she's smarter than he is.
- Superpowered Evil Side: Stiles has the devastatingly powerful Void fulfilling this role. The Oni who were explicitly hunting it were defeated by it with ease.
- Survivor Guilt: In his hallucination, Stiles reveals that he feels guilty for his mother's death and believes that his father blames him.
- Teen Genius: Stiles is an extremely bright teenager, often coming up with the answers to problems both supernatural-related and mundane alike. For example, Stiles is the first to realize that Scott was cursed with lycanthropy after Scott was bitten.
- That Came Out Wrong
- That Man Is Dead: Invoked when Stiles is possessed by the nogitsune.
- Trademark Favourite Food: Stiles' favourite food are curly fries. Coincidentally, he seems to share this favourite food with his father, Sheriff Stilinski.
- Undying Loyalty: Despite Scott being a werewolf who brings much unwanted drama into Stiles life, Stiles still manages to stand by Scott no matter what. Similarly, as much grief as Stiles causes his father, he always has his father's back, since they're the only family the other has.
- Unfazed Everyman: Despite being one of the only humans in the central group, he's remarkably unfazed by all of the weird stuff around him and at times is even less surprised by supernatural things than the werewolves themselves.
- Wait Here: Stiles tells Lydia to wait in the Jeep while he and Scott look for Kira in "Galvanize". When she asks why, he tells her that he's only got one bat.
- Weirdness Magnet: Stiles often laments his tendency to be stuck in the middle of whatever supernatural mess is unfolding in Beacon Hills, despite being a normal human.
- Would Not Hit a Girl: Discussed. Stiles says he might need to revisit this policy.
Derek Hale (portrayed by Tyler Hoechlin & Ian Nelson)
"You've been given something that most people would kill for. The bite is a gift."
The original Beta werewolf in town, and to those who don't know what he really is, a vicious criminal. He seeks out Scott after the latter is bitten, for reasons that the teenager doesn't quite understand.
- Anti-Hero: Although Derek has generally good intentions, he does morally questionable things, like dosing people with Kanima venom and trying to kill Lydia, to achieve his well-intentioned goals.
- Authority Equals Asskicking: While Derek is an Alpha, he is significantly stronger and tougher than other werewolves, including the betas of his pack (Isaac, Boyd, Erica). Derek calls all of the shots because not only is he the Alpha but he is also the strongest physically.
- Big Brother Mentor: As the only experienced, sympathetic werewolf, Derek takes first Scott and then Isaac, Boyd and Erica under his wing and teaches them how to use their powers.
- Blue and Orange Morality: Was born a werewolf, raised in a family of werewolves, and will always do things the werewolf way. Whether or not that lines up with anyone's notions of 'good' is a crapshoot.
- Brutal Honesty: More often than not, Derek doesn't sugarcoat the truth. He's pretty open and straight to the point when it comes to his own opinions.
- Butt Monkey: He's been shot, poisoned, apparently murdered, tortured and beaten by way of setting the stakes and showing off the worst the baddies can offer. Nothing good happens to him.
- Can Not Spit It Out: Much of the mystery in Season One stems directly from the fact that while Derek actually talks quite a bit, he never just gets to the point when he can be cryptic instead. "No, I didn't bite you Scott." and "The Argents hunt werewolves." would have literally taken seconds to get out the very first time he met Scott.
- Cool Car: For someone who seems to be poor and homeless, Derek sure owns a nice, expensive car: a black 2010 Chevrolet Camaro.
- Cynical Mentor: Whether it's to Scott or to his Betas, he's not the best mentor around. He tends to instinctively see the worst in people and leaps to conclusions based on worst case scenarios.
- The Comically Serious: His glaring or hostile reactions to other people's actions, especially Stiles', are often much funnier than the initial joke.
- The Cynic: Derek is very cynical, jaded and pessimistic in general. He believes that the world is nothing but a dark, lonely and dangerous place and that everything bad will happen. He is the opposite of Scott, The Idealist, though it is completely understandable as to why Derek would have this kind of outlook and mentality, considering all of the tragedy and problems that he has faced in his life.
- Dark and Troubled Past: Several years before the start of the show, his whole family was murdered by hunters, specifically Kate Argent, who seduced him to find out the family's weak spots. Derek obviously didn't take it too well. Later, itís also revealed that his first love was bitten by Ennis, leading to him turning from a happy teenager into the emotionally detached person he is today.
- Death Glare: Derek will often stare down his opponents whenever he is preparing to attack or fight.
- Desperately Craves Affection: The fact that Derek was desperately trying to connect with Scott in Seasons 1 and 2 and the fact that he created his own pack by turning a bunch of troubled teenagers into werewolves, tells you that Derek was yearning for love, companionship and friendship.
- Destructive Romance: Derek's fling with Kate Argent not only destroyed him as a person, but also got his entire family killed.
- Disapproving Look: Derek gives one to Isaac as he tries to talk to him about Derek's sister.
- Does Not Like Guns: Justified; he's been shot repeatedly.
- Don't Sneak Up On Me Like That: Derek really doesn't like being surprised. Given that he has Super Strength, this doesn't turn out particularly well for whoever startled him. Stiles is the most common recipient, since he's human and all.
- Drill Sergeant Nasty: He's pretty brutal when training the younger pack members, though he only does it because he really thinks it's the best way to keep them safe.
- Face Heel Revolving Door: The narrative has him walk through this in circles. Generally it's a result of his moral compass being skewed towards survival rather than being good in the strictest sense.
- Good Is Not Nice: Stiles remarked in the first season that Derek "kind of scares him", but there's rarely legitimate reason to doubt that he has good intentions in the end. He's just really stand-offish.
- Good Thing You Can Heal: Like all werewolves, Derek can regenerate from most injuries that aren't based on werewolf weaknesses.
- When a wolf's bane infection threatens to kill him, he orders Stiles to cut his arm off, assuring him that it'll heal.
- While teaching Scott, he notes how Scott was forced into human form by injuries and asks him about connection. Rather than just stating the obvious, Derek takes Scott's moment of hesitation and breaks Scott's hand. Then, he says "pain".
- Hero with Bad Publicity: He protects Beacon Hills from supernatural threats like the Kanima but to the majority of the residents he is a vicious criminal, in part because he is initially the primary suspect in his sister's murder.
- Heroic BSOD: Has two: The first is when he's forced to kill Boyd by Kali; he's utterly gutted. The second (well, chronologically, first) is as a teenager, when his first love, Paige, is forced into accepting the bite by Ennis, and her body rejects it, causing both her death and the beginning of his frosty personality shift.
- Hell-Bent for Leather: Derek and his black leather jacket. This includes his pack.
- His Story Repeats Itself: Both Derek and Scott have fallen in love with an Argent (Kate and Allison respectively). Derek makes efforts to try to get Scott to not be in a relationship with Allison, likely out of fear that things will turn out as poorly as they did for him.
- Ineffectual Death Threats: Derek is always threatening to rip out Stiles' throat or cut off his head, but he never comes close to following through on any of his threats and even protects Stiles on numerous occasions. His enemies, however, are a different story...
- Jerkass FaÁade: There are times, usually when he is really worn down, that Derek's jerkass mask slips and he comes across as just a very weary good guy who is scared to show that he cares. This runs in parallel with his penchant for constantly threatening to kill people like Scott and Stiles, even though his failure to carry through with his threats and tendency to protect them from danger make it clear that he is just posturing.
- Jerk with a Heart of Gold: He may seem like a rival and is a bit of jerk to Scott and his friends, but he seems to genuinely care for Scott, his pack members, and even his sometime-sidekick Stiles. For example, he places himself at serious risk to rather unsuccessfully provide cover for Stiles to escape the Kanima, as well as rescuing Scott from being killed by Victoria Argent.
- Knight In Sour Armour: Derek is extremely cynical about life in general, however, he doesn't give up and keeps trying to do the right thing.
- Le Parkour: Derek often leaps and jumps on cars and across buildings rather easily, like most werewolves.
- Living Lie Detector: Like all other werewolves, he can tell when someone is lying by their heartbeat.
- Made of Iron: Yeah, Derek's a tough ol' werewolf, everybody knows that. But even by werewolf standards, the amount of physical abuse that Derek manages to survive and then shake off is rather astounding.
- Mr. Fanservice: Not an episode has gone by where Derek hasn't been shirtless or wearing a tight-fitted top that shows off his muscles. Stiles is even able to manipulate Danny into some pro boner.. er, bono hacking by making Derek change shirts in front of them.
- Morality Pet: He has a lot of them. Originally it is Scott and (sometimes) Stiles who push him towards heroism; the list grows to include Jennifer Blake, Cora, Isaac, and Boyd.
- Neural Implanting: When his powers go haywire under the influence of monkshood poisoning, he accidentally implants his memories of the Hale fire and some werewolf relevant trivia into Jackson.
- No Ontological Inertia: Derek said there's a rumor that a turned Beta may be able to be cured by killing the Alpha who turned them. However, it doesn't say what happens to any other Betas the Alpha may have turned, so it would at most be situational, or, it could just be a Motivational Lie Derek told in order to get Scott to cooperate with his plans.
- No Sense of Personal Space: If someone has a personal bubble, Derek is going to invade it. He does this to practically everyone in the show, though Stiles tends to be the most common recipient.
- No Social Skills: Derek's cryptic and standoffish behavior isn't that strange by werewolf standards, but he often comes across as an anti-social creeper to humans.
- Not Quite Dead: Derek, in "Lunatic". In the previous episode, he gets clawed in the back by the Alpha, while Scott and Stiles make a run for it. We see him hit the ground, but he turns out to be fine.
- Offscreen Teleportation: Derek seems to appear out of nowhere in the weirdest places, including the boys' locker room.
- Passing the Torch: Ends up doing this to Scott, declaring him the new protector of Beacon Hills.
- Perma Stubble: Derek is always sporting a small amount of facial hair and he never seems to shave anymore. In the Pilot, Derek is completely clean-shaven. Looks like spending time saving and protecting Scott has made Derek stop shaving.
- Perpetual Frowner: The number of times he actually smiles on the entire show can be counted on one hand.
- Poor Communication Kills: Most of the plot of the first five episodes in Season 1 could have been skipped if Derek had just taken five minutes out of brooding and told Scott he hadn't been the one to bite him.
- Power Incontinence: Briefly, when shot with a wolfsbane bullet, Derek has trouble controlling his werewolf abilities.
- Red Eyes, Take Warning: Typical for Alphas, Derek's eyes go red when he is preparing to attack or fight (or trying to look cool for newly-turned betas).
- She Is All Grown Up: Kate's predatory "This one grew up in all the right places" implies all his muscle was gained in the six years he and Laura spent away from Beacon Hills. It also implies he wasn't what could be considered "grown up" when she was sexually manipulating him.
- Shirtless Scene: Derek gets one in many episodes in order to fill his role as Mr. Fanservice.
- Sour Outside, Sad Inside: Derek is gruff to an extreme, but carrying a great deal of guilt and self-loathing inside over the death of his family.
- Stalker Without a Crush: Derek initially has a tendency to follow Scott around to be sure newly-bitten Scott wasn't being too destructively disobedient. Later, he stalks the teenagers that he's looking to recruit as Betas. Stiles has even called him out on his stalking tendencies.
- Stealth Hi/Bye: Derek's primary method of entering scenes is showing up just after everyone else is convinced no one else is around. It tends to freak the other characters out a bit.
- Stepford Snarker: Derek sometimes uses sarcasm and cutting remarks to hide his inner and emotional vulnerability or pain.
- Survivor Guilt: Derek obviously blames himself for his family's death, as Kate Argent seduced him to get to his family. This also applies to Boydís death, since it was technically at Derek's hands.
- Tattooed Crook: Even though he's not actually a criminal, Derek has a triskelion tattoo between his shoulder blades.
- Tranquil Fury: Werewolves use anger to transform and gain power. Then, they use an "anchor" to stay human and in control. Scott's anchor is Allison. Isaac's is his Father. Derek's anchor? More anger. He looks completely calm during a full moon, despite that being when a werewolf's bloodlust is at its peak, Derek no exception.
- Troubled, but Cute: Sure, Derek may be Mr. Fanservice, but he's indirectly responsible for the deaths of most of his family and his first girlfriend.
- Unfit for Greatness: Derek doesn't always believe that he is a good Alpha or strong leader, in part because things don't go well with his Betas. He sometimes needs a bit of a pep talk from others, such as Dr. Deaton or even his Uncle Peter, to make him believe that he is actually a worthy Alpha capable of leading his pack effectively.
- Used to Be a Sweet Kid: He was very much like Scott as a teenager. His girlfriend's death at the hands of Ennis ruined that.
Lydia Martin (portrayed by Holland Roden)
"Never frown, someone could be falling in love with your smile."
Lydia is the popular girl of Beacon Hills High. Lydia's life is everything that a high schooler wants: She's beautiful, her parents are rich, and she's in a relationship with the handsome lacrosse captain, Jackson. However, underneath her snobby mask lies a brilliant mind with a talent for chemistry. In the third season, she's revealed to be a banshee.
- Action Survivor: Lydia isn't even remotely an Action Girl, knows nothing about the supernatural (at first), and doesn't have any combat skills. Like Stiles, she depends on her intelligence in order to survive and deal with all of the supernatural events surrounding her.
- All Girls Want Bad Boys: Lydia seems to have a thing for troubled and edgy guys, such as Jackson and Aiden and, at least until she knew who he was, Young Peter Hale.
- Alpha Bitch: She rules the school with a manicured fist; no one showing up to her birthday party in Season 2 is considered a serious change in the usual dynamic.
- Lovable Alpha Bitch: She is genuinely nice to Allison from the beginning and even says that Allison is her best friend, and generally becomes more of a snarky, but supportive friend to the other main teenagers (Stiles, Scott, Kira, etc) over the course of the series.
- Badass Bookworm: Lydia is a Teen Genius and The Smart Girl who depends on her book smarts and her intelligence when contributing to plans, missions and battles.
- Beta Couple: Lydia and Jackson are initially the more stable, but bitchier, Foil to the relationship between Scott and Allison. The stability doesn't last long.
- Blessed with Suck: Lydia has the ability to find the dead. She's as horrified and disgusted at this as you would expect.
- Brainless Beauty: Lydia comes off as this at first, but it's later shown that she's Obfuscating Stupidity for Jackson's sake and is actually a Teen Genius who's extremely gifted in chemistry and can read archaic Latin.
- Broken Bird: Averted: Lydia goes through some very traumatic events, including being mauled and then mentally tortured by Peter Hale, having to deal with the awakening of her strange and rather creepy powers that usually lead her to finding mutilated corpses, having her boyfriend turn out to be a brainwashed lizard and then leaving, almost getting killed by the Darach, and having to deal with the death of beloved friends, but she only seems to grow stronger from her trials. After an initial Refusal of the Call, she actively tries to find out how her powers work, and how she might utilize them to best help people.
- Character Development: Over the course of the series, Lydia goes from a popular, spoiled rich girl who was an Alpha Bitch and an Ice Queen to someone who became kinder, caring, helpful and more compassionate and understanding. This is especially shown in her relationships and interactions with Stiles and Scott and she becomes friends with both of them.
- Deadpan Snarker: Lydia is commonly quite sarcastic and witty. She often engages in Snark-to-Snark Combat with Stiles and has the tendency to snark back to much more powerful adversaries, such as Kali.
- Defrosting Ice Queen: At first she wants nothing to do with the main characters bar Allison, but as she gets more and more drawn into the supernatural world, she becomes nicer to Scott and Stiles.
- Did You Just Flip Off Cthulhu?: She defiantly calls attention to the unsightliness of Alpha Kali's purposely very sharp toenails when she reveals them to the banshee, aiming to intimidate.
- Disappeared Dad: Lydia's parents are divorced and her mother has custody of her; her father rarely makes appearances in her life.
- Distressed Damsel: She's kidnapped by the Nogitsune after he's exorcised from Stiles's body near the end of season 3B, leaving it to Scott, Allison, Kira and Isaac to go rescue her.
- Diving Save: In "Motel California", she pushes Stiles and Scott out of the way of exploding gasoline from when Scott nearly blew himself up. Bonus points for letting out a Big "NO!" in the process.
- Dude Magnet: Lydia is very appealing to the opposite sex and she is never short of male admirers. She has had the affections of Jackson (who was her main love interest and boyfriend), Stiles (who has been in love with her since the third grade), Aiden (who was her love interest in season three) and as of season four, Deputy Parrish may show some interest in her.
- The Fashionista: Lydia loves fashion and trendy clothing. It seems that there is never a day when she doesn't go to school dressed up in trendy clothes.
- Fiery Redhead: Lydia is very feisty and spunky.
- Girly Girl: Lydia is very girly and feminine and she loves fashion and dressing up. Her sense of fashion is very trendy and put o date. Between her and Allison, Lydia was definitely the girly girl while Allison was more of the tomboy. She is also significantly more girly than Kira and Malia combined.
- Has a Type: Lydia loves tall, handsome and muscular bad boys. Poor Stiles thinks he's none of the above.
- Hearing Voices: How her banshee powers manifest.
- Heterosexual Life-Partners: She becomes this with Allison over the course of the first three seasons. Culminates in Allison dying while doing her best to save Lydia. Lydia is quite broken up about it throughout Season 4.
- Hidden Depths: At least in the first two seasons, only a small handful of people know how much of a genius she really is. She slowly starts showing more of her intelligence after finding out she's a banshee.
- How Do I Shot Web?: Because banshees are so rare, nobody knows much about them, so she's at a loss at how to deal with her newfound powers — especially since these powers involve her going into fugue states and finding dead bodies. This includes going to Peter Hale in order to find out more.
- I See Dead People: Hearing the dead is part of her powers as a banshee.
- The Immune: She's immune to the Alpha's bite. Turns out it's because she's supernatural herself.
- Insistent Terminology: She's not a psychic, she's a banshee.
- The Lancer: When Stiles is possessed by the nogitsune, she falls into the role for Scott.
- Lineage Comes from the Father: Played straight, but in an unusual way: Lydia's father appears to be a normal human, but his mother was a banshee like Lydia.
- Locked Out of the Loop: Scott, Stiles, Allison and Jackson don't tell her anything about the supernatural world in Season 2, with serious consequences: since nobody really talks to her, nobody realizes that Lydia is being mentally tortured and manipulated by Peter Hale into resurrecting him until it's too late.
- Mister Muffykins: Has a small, fluffy, yappy dog named Prada.
- Muggle Best Friend: Lydia is initially this to hunter Allison, as their normal-girl friendship contrasts with Allison's double life. Subverted when it's revealed that between the two of them, Lydia is the one with supernatural powers.
- Nerds Are Sexy: Played with. Lydia is considered both very intelligent and very beautiful in-universe, however she purposefully appears as a Brainless Beauty because she fears that showing her intelligence makes her less attractive. Starts to play this straight in later seasons by showing her smarts without caring for people's opinions.
- Obfuscating Stupidity: She dumbs herself down for Jackson's benefit; in reality, she has a 5.0 GPA and is a master chemist at the age of sixteen. She also happens to know archaic Latin.
- Only Friend: Mutually with Allison. Although Lydia is the popular girl, the only person other than her boyfriend that she is seen to be associated with is Allison and vice versa. This changes in season 3 when she becomes closer to the rest of the main characters.
- Our Banshees Are Louder: Lydia's powers manifest both as hearing the dead and -very traditionally- by screaming when a death has or will occur. As Peter explains, banshees scream to drown out noises that might distract them from listening on a psychic wavelength only they can hear. They can also use their scream to purposefully hurt other supernaturals, as fellow banshee Meredith demonstrates later on.
- Psychic Powers: She seems to have a sixth sense about supernatural happenings, due to being a banshee.
- Really Gets Around: In Season 1: In a ten-minute span in one episode, she flirts with Jackson (her boyfriend), Scott (her friend Allison's boyfriend) and Mr. Argent (her friend Allison's father). After her split with Jackson at the start of Season 3, she spends the night before the first day of the new school year with a hot jock and scouts freshmen for eligible "candidates."
- Refusal of the Call: She's in serious denial about her powers in the first half of season 3. Later on she starts embracing them to help the pack and people in need.
- Rich Bitch: Her mother is rich and gets her whatever she wants, and she's the Alpha Bitch of Beacon Hills High. Loses the bitchiness as she defrosts, later on loses the "rich" as her family is going through financial problems in Season 4.
- Sanity Slippage: After getting bitten by Peter, she begins to have some serious hallucinations. She also runs naked through the woods. She gets better, though.
- The Smart Girl: Lydia is the smartest character on the show. She's a shoe in for valedictorian with her 5.0 GPA and her deep knowledge of a wide variety of subjects. This is invoked in-universe several times: In "Motel California," for example, she's seen browsing a book on Quantum Theory for some "light reading" on a school trip.
- Smart People Know Latin: She got bored with classical Latin, so she taught herself the archaic version.
- Snark-to-Snark Combat: Often bickers with Stiles with dripping amounts of sarcasm to match his. It's also a big component of her relationship with her mother.
- Teen Genius: In Season 1, she's a sixteen-year-old sophomore who can make Molotov cocktails from memory using the supplies in a high school chemistry room.
- You Are Better Than You Think You Are: Lydia gives Stiles one of these in "More Bad Than Good", getting him past his Nemeton-induced Heroic BSOD. She reminds him that he's the one who "figures it out." The fact that she needs him to save her from a steel trap that's a hair away from going off on her ankle takes it Up to Eleven.
Jackson Whittemore (portrayed by Colton Haynes)
"I have an unfair advantage. You see these cheekbones? Aerodynamically suited for speed in water."
Like Lydia, Jackson has a great life: his family is filthy rich, he's dating the most popular girl in school, and he's the captain of the lacrosse team. Everything changes, however, when Scott begins to outclass him - both on and off the field - because of his newfound abilities. Jackson, refusing to take second place, tries to figure out what Scott's really up to.
- Always Someone Better: Jackson feels that Scott stole the spotlight from him and therefore, Jackson begins to resent Scott and becomes Scott's main rival.
- Bastard Boyfriend: Jackson isn't always the best boyfriend to Lydia and doesn't always treat Lydia respectfully. In fact, there are times when Jackson is just downright abusive and jerkish towards Lydia.
- Big Man on Campus: Jackson likes to think of himself as the charismatic guy at the top of the school social ladder, but in reality, he is just a Jerk Jock who is arrogant and cocky.
- Blond Guys Are Evil: More like Blond Guys Are the epitome of Jerk Jock, and he later proves to have shades of Jerk with a Heart of Gold at times
- Bullying a Dragon: Jackson has a bad habit of being an utter dick to Derek, Peter, and Chris even after he found out about how dangerous they were. He also tries to extort Scott after finding out he's a werewolf. Subverted when Scott wolfs out and slams him into a door, giving a hint that maybe, just maybe, you shouldn't try antagonizing someone who can rip you apart.
- Competition Freak: Jackson is a highly competitive person by nature, feeling that he has to justify his worth to his adoptive parents.
- Cool Car: As a rich kid, Jackson drives an expensive Porsche, and he has no problem with flaunting his expensive car, either.
- Dark and Troubled Past: Jackson has had a rough life growing up. Parental abandonment, having no identity, and having no idea where he came from. A lot of his personality makes more sense when you realize he has a lot of pent up aggression from being abandoned, as well as self-image issues.
- Eye Scream: A snake crawls out of his eye.
- Gone Horribly Wrong: Derek bit him; but instead of becoming a werewolf, his body rejected the bite and he became a reptilian creature, the Kanima.
- Hot Guys Are Bastards: Jackson is seriously attractive and isn't breaking the stereotype that hot guys are major jerks with huge egos.
- Hidden Depths: Despite his Jerk Jock status, he's very much the Only Sane Man at the start, and the only person not already in the loop who is the least bit curious about all the weird things happening to Scott.
- I Just Want to Be Special: Much of his aggression towards Scott in Season 1 is because of Scott stealing his 'star' status, which makes him fall apart psychologically. Derek accidentally mind-whammying him while poisoned doesn't help.
- Ice Queen: Jackson is very arrogant, cold, cocky and generally unfriendly.
- Inferiority Superiority Complex
- Interspecies Romance: Starting in Season 2, Jackson and Lydia's relationship seems to be interspecies because all signs point towards one of the two of them being the Kanima. It's Jackson. Just when the Kanima situation is dealt with, Jackson reverts to a normal werewolf, keeping the situation going, and then Lydia discovers she is a banshee, making the relationship was interspecies all along.
- Jerk Jock: Jackson is the epitome of a jerk whose specialty is being a good athlete: cocky, arrogant and thinking he's better than everyone else. He likes to be the star on the lacrosse field and doesn't take lightly to any competition. When Scott gains werewolf abilities, Jackson becomes very jealous of him, and tries everything to find out his secret.
- Jerk with a Heart of Gold: He does care about his friends, few as they are.
- Jerkass Has a Point: As much as an asshole he might have been for blackmailing Scott, he was right on the nose when he called Scott out for being a cheater since he was using his werewolf abilities to play lacrosse. Scott himself acknowledges this in Season 4 when he tries to just use his human abilities instead of his wolf abilities.
- Lonely Rich Kid: Jackson is spoiled, rich and gets everything he wants. However, his deep-seated insecurity causes him to keep both his parents and other people at arm's length through coldness and arrogant behaviour.
- Mr. Fanservice: Jackson is an attractive young athlete drawn into a scary supernatural world: naturally, this leads to many scenes in locker rooms with lots and lots of shirt-changing.
- Only Sane Man: He's the only one remotely confused by Scott's newfound athletic prowess.
- Out-of-Character Alert: When Stiles kidnaps Jackson and doesn't want Jackson's parents to realize he was missing, Stiles sends a text from Jackson's phone impersonating him to explain why Jackson didn't come home. However, since the text ended with "love you" to his parents, they know something was wrong because Jackson hasn't been able to say that to them since he found out he was adopted.
- Parental Abandonment: Jackson was adopted and didn't know who he is real parents were, contributing to his lack of identity.
- Put on a Bus: Jackson did not return for Season 3 because Colton Haynes joined the cast of Arrow. In-universe, Jackson is going to school in Paris. Given how well Arrow is doing, it's likely that this will remain a Long Bus Trip, since it's easy to bring Jackson back between seasons.
- Sanity Slippage:
- Throughout Season 1, after Derek scratches Jackson on the back of his neck, leaving him wounded, Jackson starts to feel off and display strange behaviour. It was mostly because Jackson suffered from aconite (wolfsbane) poisoning because when Derek had scratched Jackson, Derek was dying from the bullet which contained aconite wolfsbane.
- Also, after Derek gives Jackson the bite in the beginning of Season 2, his body rejects the bite and starts to ooze black goo out of every orifice, on top of vivid hallucinations.
- Shipper on Deck: Jackson picks up on Danny's crush on Matt and encourages his friend to go for it.
- Tender Tears: When he realizes just how far Scott will go for him, he cries.
- Wound That Will Not Heal: When Derek accidentally claws him in the back of his neck. It not only doesn't heal, but leads to bizarre hallucinations.
Kira Yukimura (portrayed by Arden Cho)
ďHi, I'm Kira. You knew that. I knew you knew that. I don't know why I just told you that again.Ē
Kira is the half-Japanese, half-Korean New Transfer Student
to Beacon Hills who instantly falls for Scott. From her mother's side, she has inherited the abilities of the thunder kitsune, which she was unaware of until she was drawn into the conflict against the Nogitsune, wherein her powers awaken and prove to be valuable against the chaos.
- Action Girl: With her katana and kitsune abilities, Kira can hold her own against werewolves and the Oni.
- Adorkable: See her quote above for details.
- All Asians Know Martial Arts: Played with: she had no clue of her abilities until her lineage awoke, and even then she still was shocked at her fighting skill.
- Dork Knight: Just like Scott, Kira doesn't let being a ball of awkward stop her from stepping up to save the town.
- Faux Flame: As part of her kitsune abilities, Kira is surrounded by a nimbus of golden flames when her photo is taken.
- Genki Girl: Kira often slips into bubbling enthusiasm, especially regarding Scott.
- How Do I Shot Web?: Her grasp on her kitsune abilities is tenuous at best, leading her to, for example, blow out a lightbulb while attempting to use her powers on it.
- Katanas Are Just Better: Kira's inherited katana is the only sword getting any practical battle use, contrasting with Gerard's broadsword only being used for executions.
- Kitsune: Though Kira is a kitsune and has many of the related powers, transforming into a fox doesn't seem to be one of them.
- Lady of War: Has a certain elegance in her battle style that the other heroes lack.
- Lineage Comes from the Father: Inverted. Her powers are inherited from her kitsune mother.
- Motor Mouth: When she gets nervous or shy, she tends to speak very quickly.
- New Transfer Student: Halfway through Season 3, Kira transfers to Beacon Hills High School when her father gets a job there.
- Nice Girl: Not that any of the other main characters are necessarily mean, but she's probably the nicest out of them, being the most friendly and approachable.
- Shock and Awe: Kira is the thunder kitsune, and she has the power to control electricity as a result.
- Supernatural Gold Eyes: When her kitsune side shows, Kira's eyes take on a golden color.
- Took a Level in Badass: In the span of five minutes, Kira moves from being powerless against the Oni to taking them out with ease.
Malia Tate (portrayed by Shelley Hennig)
"Thanks for invading my home, for putting me on the run, for turning me back to human so that I could look at my father everyday and try to figure out how to explain to him that the reason my sister and mother are dead is because I almost ate them on a full moon. Thank you so very much."
A werecoyote, Malia involuntarily changed under the full moon as a child and caused a car accident which killed her mother and sister. Ashamed by this, she spent eight years in the wild as a coyote and avoiding her father. It was only through the intervention of Scott and his pack that she became human again; now, as a member of the pack, she is readjusting to her humanity and figuring out her feelings for Stiles.
- Action Girl: She's a werecoyote, so she is quite capable of taking care of herself in dangerous situations.
- Brains and Brawn: Though by no means stupid, she's still the Brawn to her boyfriend Stiles' impressive Brains.
- Book Dumb: Malia isn't too fond of mathematics and thus struggles in school. Regardless, she is an adept thinker.
- Complaining About Rescues They Don't Like: Malia doesn't consider being forcefully turned back into a human a "rescue", no matter what Stiles and Scott might think, and doesn't hesitate to tell them this.
- Enfant Terrible: Malia thinks she's was a horrible, murderous child; in reality, while she may have killed her family, it wasn't her own fault.
- How Do I Shot Web?: As a coyote, Malia is unable to transform back into a human. Once forced into human form, she's unable to shift back or use her other wolf powers. Fortunately for her, Scott steps up as her mentor.
- Humanity Ensues: Scott's Alpha roar snaps her back into human form. She initially doesn't know how to shapeshift back to being a coyote, and she is not happy about having to live as a human.
- I Wished You Were Dead: The last thing Malia said to her adoptive mother. Since she caused the car crash that killed her and her younger sister, and has no memory of the exact circumstances, she wonders if she might have killed them deliberately.
- In the Blood: After learning who her father is, she worries she might end up a killer like him (as she already considers herself responsible for the death of her adoptive mother and sister).
- Know When to Fold 'Em: As soon as Malia realizes she's no match for Peter, she hands him what he wanted.
- Locked Out of the Loop: The other characters keep the fact that she's Peter's biological daughter from her for quite some time. She's not exactly pleased when she finds out.
- Long-Lost Relative: She's Peter's biological daughter and therefore first cousin to Derek and his sisters.
- Missing Mom: Malia's biological mother seems to have abandoned her at birth. Given that she seems to be a supernatural assassin who is wanted by the US government, that might not be such a bad thing.
- New Transfer Student: Once she joins Scott's pack, Malia decides to enroll at Beacon Hills High School as the newest transfer student.
- Not Good with People: Malia relies on her coyote instincts first, which ends up in blunt honesty, inability to understand some phrases, and sarcasm, which can put people off. Stiles is trying to teach her how to be a functional human being.
- Self-Made Orphan: Might have caused the death of her adoptive mother and sister.
- Tsundere: Her first interaction with Stiles at Eichen House is to deck him. Later that night, they hook up.
- Wild Child: From the age of 9 to 17, Malia remained alone in the wilderness as a coyote. She can act as a stable and functioning human, but she feels extremely uncomfortable when not in her canid form.
Other Beacon Hills High School Students
Danny Mahealani (portrayed by Keahu Kahuanui)
"If I come back and you're lying dead underneath a pile of weight, I'm taking the Porsche."
The goalie of the lacrosse team, and Jackson's best friend. Secretly a massive tech genius, he helps Scott's gang with their computer issues while being none the wiser about what's going on in Beacon Hills. At least that's what he made everyone believe, until he admitted to knowing about the supernatural to Ethan in the Season 3 Finale.
- Chuck Cunningham Syndrome: After revealing he knew about everything all along, he doesn't appear in Season 4 with no explanation of his absence.
- Closet Geek: He's so far helped both Stiles and Jackson with rather complicated tech work.
- Deadpan Snarker: Danny has a tendency to make dryly snarky comments in response to Jackson's more self-obsessed moments.
- Lovable Jock: He's one of the nicest guys on the lacrosse team and even Jackson is never mean to him.
- Meaningful Name: In keeping with the werewolf theme, "Mahealani" refers to the day when the full moon begins to lose its roundness.
- Morality Pet: He's Jackson's best friend and the only person Jackson is consistently not a total jerk to. If it weren't for his friendship with Jackson, Jackson would likely be less sympathetic than the main villains.
- Nice Guy: Almost all of the characters like him and he's consistently nice to everyone around him, except when Stiles is pestering him.
- Playful Hacker: Danny's computer skills are apparently high level as he has a criminal record from a computer hacking incident when he was 13 years old. He says the charges were dropped, and there's no indication he's done anything malicious with them.
- Straight Gay: When he's not, you know, playing lacrosse, his interests extend more towards hacking and other programming than, say, musical theatre.
- Teen Genius: In contrast to Lydia's academic prowess and Stiles' attempts to actually do the research, Danny's expertise is technology.
- Twofer Token Minority: Before Boyd joined the team against Derek's instructions, Danny was the only non-white, non-main lacrosse boy with a name. He's also the only out gay character of any significance in the first two seasons, and most scenes he's featured in manage to draw attention to his sexuality.
- Weirdness Censor: Despite being Jackson's best friend, playing lacrosse with Scott, Isaac, and Boyd, being attacked by the kanima, writing a paper on telluric currents, and even dating Ethan, Danny seems to have no awareness of the greater supernatural world. Subverted when he breaks up with Ethan in the Season 3 finale because he just can't keep dating a werewolf; unbeknown to everyone else, he got clued-in at some point.
- Woman Scorned: Played for Laughs; after being paralyzed by the Kanima, Danny is asked if he's okay. After receiving confirmation that the paralysis happened to his ex as well, he smiles blissfully and says he's great.
Isaac Lahey (portrayed by Daniel Sharman)
"I came to win."
Isaac is the first member of Derek's pack, bitten due to his horrid
home life. After an initially rocky start in dealing with his powers, he becomes one of Derek's right hand men, until eventually joining with Scott's 'pack' of sorts and moving in with him.
- Abusive Parents: According to Isaac, his father used to lock him in a freezer all the time. Not to mention, Mr. Lahey used to throw glasses all over the house so that Isaac would have to clean it up. And the worst of it all? Throwing glasses at Isaac, so that shattered pieces of glass hit his face and almost blind him. Possibly the most chilling example of the abuse Isaac suffered were the nail marks in the cement floor of the basement leading to the freezer.
- Adorkable: Isaac becomes much more adorable and approachable after being under Scott's influence. He is easily one of the most endearing characters on the show. The most adorable moment for Isaac was in 2x11 when he used his powers to take some of the pain away from a dying dog. Isaac shed a few tears and was feeling happy that he could heal puppies. One of the most adorable moments on the show.
- Berserk Button: It has been shown that hurting or harming Scott in any way, shape or form will turn a usually calm, gentle and mild-mannered Isaac into a violent, raging, aggressive and extremely out of control werewolf. DO NOT hurt Scott under any circumstances. He will beat you to a bloody pulp ( as was shown in 3x05 when Isaac beat up Ethan for physically harming and wounding Scott) and he probably won't stop until you're dead either. It doesn't matter who you are (Ethan is an Alpha after all).
- Beware the Quiet Ones: Isaac is not overly talkative and is quite quiet and keeps to himself the vast majority of the time. But when he or anyone he holds dear is threatened, Isaac's more aggressive side will come out to play.
- Dark and Troubled Past: His father was extremely abusive.
- The Determinator: Once he was hit with the Kanimaís paralytic agent, once he was rammed at full speed by Kanima!Jackson. And on both occasions he shows enough determination to actually crawl across the floor and stand up.
- Drunk with Power: In his first episode as a wolf, he's shaken and unsure; after this, he revels in being one, becoming cocky and snide. This stops after his Heel-Face Turn.
- Dysfunction Junction: Isaac came from a highly abusive and dysfunctional family and home life. It is why Isaac had many trust issues and why he had a difficulty opening up to people in general.
- Fake Guest Star: Isaac never made it into the opening credits, but is pretty much a main character in Season 3.
- Fully-Embraced Fiend: Initially, Isaac revels in his werewolf powers, including by scratching a line of lockers with his claws just for the hell of it. Even after he mellows out, he still has no qualms using his strength to intimidate innocent people when Scott is unwilling to do so.
- Heel-Face Turn: Towards the end of Season 2, Isaac goes from being a cocky, standoffish, impulsive werewolf whose intentions weren't so noble, to a much kinder, more compassionate, sensitive individual who just wants to do the right thing.
- Heroic Willpower: Out of the three new Betas heís the one who fully controls his transformation using his Anchor (Granted he is the only one who actually ask Derek how one could control it)
- Hope Bringer: Coming back to help Scott when he needs it the most after his Heel-Face Turn. After all, he "came to win." The look of hope and relief on Scottís face is unmistakable when he realized he had another ally during his Darkest Hour.
- Missing Mom: It appears Mrs. Lahey hasn't been around for a while, though we never discover what happened to her.
- Nice Guy: Isaac seems to have been this as a human. After a short stint as a Jerkass following his transformation into a werewolf, he returns to his old personality.
- Power of Love: A platonic one variation, but quite notable one. When Derek asks him what turned to be his Anchor, Isaac answers that it was his father. When a surprised Derek points out how much of an Abusive Parents his father was, Isaac just smiles fondly and states that he wasnít always like that, obviously drawing on his happy memories with his father to serve as his Anchor.
- Put on a Bus: Daniel Sharman went on to become part of The CW's The Originals, so at the end of Season 3, Isaac and Chris Argent travelled to France, where Isaac has been staying since.
- Sixth Ranger: Isaac becomes more of this to Scott, Stiles, Allison, and Lydia over the course of Season 3A. This development already starts at the end of season two, where unlike Boyd and Erica he decided to stick around and help in the fight against Gerard and the Kanima.
- Tender Tears: When he uses his Healing Hands ability to drain some of the pain of a puppy
- Took a Level in Badass: Before Isaac was bitten and became a werewolf, he was rather weak, vulnerable and didn't really defend himself, especially against his abusive father. After he was bitten, he became much stronger and more confident.
- Took a Level in Jerkass: Initially after his transformation into a werewolf, he revels in being stronger and faster, and plans to take revenge on people who were mean to him - such as Lydia. Eventually, after becoming more used to his new circumstances and reducing a sick puppy's pain , he takes several levels the opposite way.
Liam Dunbar (portrayed by Dylan Sprayberry)
"I don't mean I'm not strong or I'm never gonna learn how to be in control. I mean everything else. You and your friends try to protect everyone. Have you been whole this the whole time? I mean, how are you all still alive?"
A freshman and extremely gifted Lacrosse player, who transferred to Beacon Hills Highschool in Season Four. Scott accidentally bit him trying to save his life and he consequently became Scott's first beta.
- Dark and Troubled Past: He does have some anger management issues which lead to him getting expelled from his last school after vandalizing his former coach's car. His old Lacrosse team still hates him for it.
- Emergency Transformation: A twist on the usual formula. Scott is forced to bite Liam not due to the latter being grievously wounded, but because he's dangling off a ledge. Scott tries to save him but his arms are being held back, so the only thing he can grip Liam's arm with is his teeth. The transformation itself was unintentional, but an unavoidable side effect.
- Fun with Acronyms: Liam has intermittent explosive disorder. Stiles is quick to note that he's an IED.
- Generation Xerox: Purposefully invoked by the show. Liam's first few days as a werewolf mirror Scott's pretty much exactly, right down to a doofy older werewolf telling him they "are brothers now" and the clever Muggle Best Friend, who seems to be slightly more observant than Liam.
- Hair-Trigger Temper: Suffers from Intermittent Explosive Disorder. Also the reason he got kicked out of his last school. He actually seems to get calmer once he has adjusted to being a werewolf.
- Heterosexual Life-Partners: Mason is his best friend.
- "I Know You're in There Somewhere" Fight: Liam experiences one when Scott attacks him while transformed into a Berserker. He manages to snap him out of it.
- New Transfer Student
- Tagalong Kid: His role in the latter half of Season 4.
- Took a Level in Badass: He was a stellar athlete before, but after his werewolf transformation, he becomes a pretty respectable fighter.
Erica Reyes (portrayed by Gage Golightly)
"I have beautiful everything."
The second member of Derek's pack, Erica was originally a girl with severe epilepsy, and a frequent patient under Melissa's care. Once she's bitten, she becomes an extreme vamp
with eyes for, well, pretty much everyone, having made advances on Derek, Scott, Stiles, and Allison.
- Action Girl: Erica was not an action girl before she became a werewolf. After she turned, she became significantly stronger and a much more capable fighter.
- Action Fashionista: Erica is an Action Girl but also seems to have a penchant for fashion and trendy clothing.
- Alpha Bitch: Tries on this persona upon getting the bite, but slowly develops a more down-to-earth personality over the course of Season 2.
- Blessed with Suck: Lycanthropy cures her epilepsy, the bane of her existence. But . . .
- She was turned right when the Hunters were cracking down, trumping all her other gifts with brutal persecution.
- The Kanima briefly returned her epilepsy with a claw swipe, giving her a seizure that had to be stopped by breaking her arm to trigger the healing process.
- On her first full moon, her high pain tolerance earns her the prize of being the only one of Derek's whelps to get screws drilled into her skull.
- Character Death: Killed by Kali. Seen only in a flashback, though her body is shown in the present time.
- Convulsive Seizures: Erica was an epileptic before Derek turned her.
- Curse That Cures: Her epilepsy disappeared after she was turned into a werewolf.
- Even the Girls Want Her: Several students immediately throw up their hands to be her lab partner when her name is called for pairings. Its a quick shot, but one of them is a girl.
- From Nobody to Nightmare: When Erica's first introduced, she's a troubled, skittish epileptic ostracized by the entire school. Then Derek gives her the bite. Who's Laughing Now??
- Fully-Embraced Fiend: Of all of the newly-turned werewolves in the show, she is the one who most embraces her new powers, becoming the center of attention at school. Though she initially has a lower social status than even Scott, she intentionally jumps to the top of the heap, constrasting Scott's rise as an unintended (though not unappreciated) result of trying to be better at lacrosse.
- I Will Only Slow You Down: When Allison shoots her with arrows while she and Boyd are trying to run away from Beacon Hills, she screams at Boyd to keep running.
- The Vamp: After a childhood of feeling sickly and unattractive due to her epilepsy and the meds she had to take for it, Erica wants as much attention as she can possibly get when the bite makes her healthy and beautiful. It goes to the degree of overcompensation.
- Took a Level in Jerkass: She revels in being callous to everyone around her after becoming a werewolf as her revenge for having received that same callousness from everyone around her.
Vernon Milton Boyd IV (portrayed by Sinqua Walls)
"I want to be like you."
The final member of Derek's pack, Boyd was originally a loner at school. Now, he has friends in Derek, Isaac, and Erica.
- Character Death: By Derek as a result of the Alphas.
- The Determinator: Human Pincushion or not, Boyd didnít for one second try to stop trying to take down Allison in order to protect Erica. Even Chris Argent was completely surprised at Boydís willpower, judging from his face when looking at Boyd
- Embarrassing First Name/Two First Names: If the combinations of tweets by Jeff Davis and MTV's legal department is to be believed, his full name is Vernon Boyd IV. Two First Names applies to the point where many fans thought Boyd was his first name and that the writers were holding out on his last name.
- Gentle Giant: Of the three members of Derek's pack, he's the calmest member, and the only one who hasn't had a marked change of attitude after getting the bite.
- Hidden Depths: He seems to have a much deeper understanding of werewolf lore than anyone else that's gotten the bite so far. He explains the symbolism of Derek's triskelion tattoo to Isaac, Erica and the audience.
- I Just Want to Have Friends: The reason he agrees to join Derek's pack
- Ordinary High-School Student: Boyd was this before he was turned into a werewolf and gained superhuman abilities.
- Taking the Bullet: An incredibly big part of the reason Boyd was made into a Human Pincushion was the fact that he was essentially shielding Erica from Dark Action Girl Allison. With his body.
- Token Minority: Boyd was the only African-American werewolf for quite a while.
- Scary Black Man: At first. The whole barely-ever-speaks thing he sometimes has going on doesn't help much, either.
Matt Daehler (portrayed by Stephen Lunsford)
"Well, Derek, not everyone is lucky enough to be a big, bad werewolf."
A charming student and photographer, who's also on the lacrosse team with Scott, Stiles, Jackson, Danny, and Isaac. He has a tremendous crush on Allison, and a tenuous friendship with Jackson and Danny. He's also the Master of the Kanima. Whoops.
- Break the Cutie: Matt suffered a horrible day once upon a time, and the rest is history.
- Death by Irony: Gets drowned by Gerard.
- Disc One Final Boss: Unceremoniously offed by Gerard, which lets him assert himself as primary Season 2 Big Bad and take Matt's place as master of the Kanima.
- Dogged Nice Guy: For Allison, who only has eyes for Scott. It later turns out that he's not as nice as he seemed.
- Evil All Along: Hiding behind the eyes of a tech-savvy photographer jock is a vicious killer hungry for the blood of anyone he feels did him wrong.
- From Nobody to Nightmare
Derek: This is the one controlling the Kanima? This kid?
- He Who Fights Monsters: Yeah, being drowned by a bunch of drunken teenagers is awful. Also awful? Murdering all of those teenagers in cold blood 5 years later.
- If I Can't Have You: He says this almost word for word. He originally defies it, but he ultimately plays it straight.
- Incompatible Orientation: Matt's heterosexuality and obvious crush on Allison get in the way of Danny trying to find someone nice after his breakup.
- The Man Behind the Man: The Kanima seeks a master. He's it.
- Monster Sob Story: He drowned in a pool when he was younger, which kicked off a...
- Roaring Rampage of Revenge: He even compares himself to Orestes, seeking vengeance against those who wronged him by standing by while he drowned.
- Stalker with a Crush: His camera is full of candids of Allison that she didn't know about. Lampshaded by Allison herself, who shoots down his 'I couldn't help myself, you're just so beautiful' Edward Cullen act and judo-flips him.
Matt: Photographers call them candids.
Allison: Well, police officers call it stalking.
- The Stoic: Whenever he wasn't overtly acting as the vengeful Master of the Kanima, his face didn't move much and practically everything he said was in a deadpan indifferent tone.
- The Unfettered: He really has one single solitary goal: Allison Argent. That, and getting revenge on the swim team for drowning him.
- Walking Spoiler
Mason (portrayed by Khylin Rhambo)
" I know something's going on. I know you don't want to talk about it. But, you're still my best friend. [...] So, when you're ready to talk, talk. Until then, I know I can kick your ass at at least one of these games."
A freshman at Beacon Hills Highschool, he's Liam's best friend, and as such, thrown into the supernatural world with no warning. He holds himself well, though.
- Distracted by the Sexy: Shirtless Brett proves to be quite distracting to him.
- Heterosexual Life-Partners: Despite being gay, he's very supportive of Liam, his best friend.
- Locked Out of the Loop: He's been very patient with Liam so far, but after battling a berserker with Lydia and the Sheriff, he's likely to demand some answers.
- Muggle Best Friend: Just an ordinary, if bright and astonishingly mature highschool kid who is friends with a teenage werewolf.
- Nice Guy: He's supportive of Liam, even though he's aware his best friend is keeping secrets. He also compassionately listens to Lydia, when she tells him about her family's recent money woes.
- Ordinary High-School Student: He actually uses the knowledge that comes with this status for some clever, detecting, figuring out that something's wrong with Garrett and Violet, because they lied about their home addresses.
- Straight Gay: Without his appreciation for Jerk Jock Brett's impressive physique, there would be no overt hints at his orientation.
- Suspiciously Similar Substitute: He does seem to fill a certain Danny-formed role, what with being the gay best friend of color to a cocky lacrosse player. Less obviously, he is a Generation Xerox for Stiles, who is the Muggle Best Friend of the older teenagers.
- Took a Level in Badass: Memorably charges a Berserker with a baseball bat in the Season 4 finale.
Garrett (portrayed by Mason Dye)
Garrett is a freshman at Beacon Hills Highschool who befriends Liam and Mason, and becomes another member of the Lacrosse team. He's also one of the assassins trying to win the bounty put out by the benefactor on the supernatural creatures of Beacon Hills.
Violet (portrayed by Samantha Logan)
Another freshman student, she's Mason's girlfriend. Like him, she's also an assassin.
Bobby Finstock (portrayed by Orny Adams)
"The bigger they are...the bigger they are!"
The mentally unstable lacrosse coach and economics teacher at Beacon Hills High School.
- The Alcoholic: According to Natalie Martin, he's been sober for 15 years. He, however, claims he still drinks every night.
- Attention Deficit... Ooh, Shiny!: When Scott is tackling his teammates, despite being goalkeeper, to get into sniffing range, Finstock pulls Stiles over and demands to know what the hell is wrong with his friend. Stiles lists bad grades, social awkwardness, and a misaligned jaw. Finstock is so intrigued by Scott's jaw that he lets the issue drop.
- Bully Hunter: He will not tolerate bullies. The orderlies of Eichen House found this out the hard way.
- Bunny-Ears Lawyer: He's ambiguously crazy, yet he's also a competent coach and economics teacher.
- Cloudcuckoolander: Talks to people that don't even exist and his motivational speeches go off on some strange tangents.
- Embarrassing Nickname: Inverted. He wants to be called "Cupcake".
- Imaginary Friend: Word of God states that Orny Adams was not given specifics on who to look at when yelling at Greenberg, with Jeff Davis presenting the possibility that Greenberg doesn't actually exist.
- Jerk with a Heart of Gold: At the end of season two, he's visibly concerned by Stiles' kidnapping and upset by Jackson's death.
"I know I yell a lot. But itís not like I hate you guys. Well, I kind of hate Greenberg, but... Thatís different. Itís Greenberg."
- Large Ham: It's best highlighted in the speeches he gives before games in the locker room.
- Messy Hair: There is not a strand of Coach Finstock's hair that sticks in the same directions as any other; he's like an anime character, in keeping with his character as eccentric hard-ass who probably doesn't own a comb.
- Rousing Speech: Finstock gives one of these to his lacrosse team before the championship game. Turns out it's the exact same speech used by the American president in Independence Day. This little fact doesn't escape the notice of Stiles and Ms. McCall.
- Sadist Teacher: And coach, though for comedic effect.
Finstock: *laughing* I don't know why, McCall, but your pain gives me a special kind of joy.
Adrian Harris (portrayed by Adam Fristoe)
"Try putting the highlighter down between paragraphs. It's chemistry, not a coloring book."
The snide chemistry teacher at Beacon Hills High School with a particular hatred for Stiles.
- The Alcoholic: Formerly, and it was during a drunken night at the bar that he told Kate Argent what type of chemicals would most efficiently burn down a large, wooden structure. This, of course, lead to the arson-murder of the Hale family.
- Asshole Victim: He gets murdered at the end of 3.04.
- Jerkass: On top of his usual behavior, Harris also knew about the true culprit behind the Hale family murders, but never came forward because he didn't want to be charged as an accomplice. He was also working with the Darach, only to be betrayed and murdered.
- Sadist Teacher: Consistently singles out and verbally abuses Stiles in class to levels that would (and should) get him fired.
- The Scapegoat: Whenever something bad happens, he is usually the first person to be suspected by both the audience and the characters.
- Stoic Spectacles: The glasses only add to the strangely intense chemistry teacher schtick. If this show wasn't live-action, you could expect Scary Shiny Glasses to be invoked for emphasis.
Jennifer Blake (portrayed by Haley Webb)
"Obviously, you've never taught high school. In 20 minutes, I have to start two dozen teenagers on the Crucible, and I honestly have no idea what I'm gonna say."
The new English teacher appearing in season 3, she is soon embroiled in the Beacon Hillls supernatural community after nearly being killed by Cora and Boyd
, and saved by Derek.
- Adorkable: She's a bubbly, friendly and very enthusiastic teacher, and geeky about all things literature. Too bad she also sacrifices people in her spare time.
- Big Bad: One of Season 3's main antagonists, and arguably a bigger one than the Alphas given that they're opposed to her as well.
- Bitch in Sheep's Clothing: And frigging how. She acts like a delightful and friendly individual, only to turn around and casually attempt to kill Lydia.
- Cool Teacher: Texts her students the closing line of Heart of Darkness, both to get them interested in the book and to inform that it is the last text they will receive in her class.
- Dark and Troubled Past: Mentions being in psychotherapy, and has been emotionally okay "for a long time".
- Deadpan Snarker: Upon having to treat Derekís injuries, she jokes that itís the weirdest first date sheís ever had.
- Distressed Damsel: Sheís been in bad situations twice since Season 3 began, requiring aid from Derek and Isaac, respectively.
- Game Face: Has one in the form of the Darach.
- Genre Savvy: Fully expects Derek to kill her, or at least tell her that nobody will believe her if she tells them what she saw. He doesn't, and actually does his best to make her feel okay.
- Humanshifting: She can shift from a beautiful woman to a repulsive humanoid figure.
- Morality Pet: To Derek.
- Nice Girl: Jennifer is a very sweet individual in a Crapsack World. Or so she seems.
- Reasonable Authority Figure: As opposed to Finnstock or Harris, sheís a soft-spoken, caring, and friendly teacher... at first, anyways.
- Secret Keeper: For all of the heroes and their supernatural activities. It turns out that she's far more aware than she lets on.
- Ship Tease: With Derek.
- Super Strength: She can crush a Sheriff's badge with her bare hands and send Scott sprawling across a room with one palm to his chest.
- Take-That Kiss: Plants one on Sheriff Stilinski in front of Stiles, Lydia, and Scott before running off with him.
- Yandere: She develops a huge torch on resident hottie Alpha werewolf Derek Hale. She advises him to pretend to be dead for a while and not call his pack. Meanwhile, she uses her psychic powers and some good old fashioned poison to get them to commit suicide and leave Derek all alone.
Melissa McCall (portrayed by Melissa Ponzio)
"Thereís a team of lawyers in the back who would break my legs. And I donít know if youíve seen my legs. But for a girl my age, theyíre still pretty hot."
Scott's snarky but well-meaning single mother, who, until recently,
has no idea of her son's double life. She's a registered nurse in the local hospital, where she often comes into contact with the victims of the latest supernatural crime.
- Action Mom: While she largely stays out of the fray, she's certainly not phased by the Alphas, as evidenced by her taking defibrillators to the Merged!Twins when they attacked her son. Generally, if Scott's in trouble, stay out of her way.
- Deadpan Snarker: Sheís probably the snarkiest person on the show. One shining example is when Scott and Isaac fall asleep watching over her, she smiles and flatly responds to it:
Melissa: ...my heroes.
- Good Parents: Not just to Scott, but to Stiles and Isaac too.
- Hands-Off Parenting
Don't either of you care that there's a police-enforced curfew
? Scott and Stiles:
...no. Melissa: *Walks Away*
. All right, that's enough parenting for tonight.
- Hello, Nurse!/Hospital Hottie: She's an R.N. at Beacon Hills Memorial Hospital.
- Mama Bear:
- She does not react kindly to Mr. Argent's implication that her son is dragging down his daughter.
- Itís also a very poor idea to screw with Stiles or Isaac around her.
- Parental Substitute: Ms. McCall often acts like a mother to Stiles and isn't at all surprised that he has a key to her house. Taken Up to Eleven in season 3B when a sedated Stiles in the hospital says to her, "Thanks, Mom." And when Stiles has to go in for his MRI in "Riddled", his support is Scott, his father, and Melissa. She was growing into one for Isaac as well.
- Team Mom: She's increasing into this role as of Season 3, helping Stiles in his research and also giving Isaac a place to stay.
- Villain over for Dinner: She gets asked out on a date by Peter, the Alpha, much to Scott's horror.
- Weirdness Censor: Averted; she eventually finds out about the supernatural goings-on in Beacon Hills and is more than willing to help her son and his friends out with whatever they need to combat the threats that come along with said goings-on.
Rafael McCall (portrayed by Matthew del Negro)
Melissa's ex-husband and Scott's father, who walked out on them when Scott was very young. Currently an FBI agent.
- The Alcoholic: Apparently had a bad drinking problem while he was married to Melissa.
- The Atoner: Genuinely wants to make good on his former mistakes, and tries to be around for Scott and Melissa.
- Big Damn Heroes: Rescues Stiles from a serial killer about to shoot him at the last second.
- Disappeared Dad: Walked out on his wife and son. He returns in Season 3.
- In-Series Nickname: His wife calls him "Rafe."
- Locked Out of the Loop: Invoked in Season 3; played with in Season 4, when he notices that his son and his friends are far too calm for the horrible things that keep happening to them, and mentions to Scott that he wants a talk upon returning from his trip to San Francisco.
- Weirdness Censor: He gets attacked by Oni twice and still seems to think there is a normal explanation to it all. He catches on eventually.
- Written-In Absence: As his actor was filming something else, Agent McCall had to return to the FBI offices in San Francisco to explain why he used his gun with deadly force, and didn't come back for the rest of the season.
Sheriff Stilinski (portrayed by Linden Ashby)
"I'm carrying a lethal weapon. If I want the curly fries, I will have the curly fries."
Stiles's father, a widower and the Sheriff of Beacon Hills. Well-meaning and overworked, he has no clue of the actual, darker levels going on within his town, despite his son fighting against them on a nightly basis.
- Adorkable: His reaction to Stiles actually getting to play lacrosse is adorable. It obviously runs in the family.
Sheriff Stilinski: Oh no
. Why is my son running out to the field? Melissa:
Because he's on the team? Sheriff Stilinski:
He's on the team
. He's...he's on the field
. MY SON IS ON THE FIELD!!! Stiles: Oh, dear God
- A Father to His Men: Really doesn't like it when you try to kill his deputies.
- Badass: Heís a hell of a shot with a pistol.
- Big Damn Heroes:
- In Season 3, he saves Dr. Deaton from hanging when Scott is unable to due to a Mountain Ash barrier.
- In the Season 4 finale, he saves Lydia and Mason by blowing up the Berserker who threatened them.
- Da Chief: Highest ranked officer of the law in Beacon Hills.
- Deadpan Snarker: He can hold his own against his son most of the time.
- Good Parents: He's a very good father and does the best that he can for his son.
- Locked Out of the Loop: While Scott wants to tell him about the supernatural world, Stiles is very adamant about keeping it secret, fearing that his father might get hurt if he knows too much. Naturally, this doesn't work out for long, and the Sheriff gets introduced to Beacon Hills weirder side at the end of Season 3A.
- Mentor: He comes to rely on Parrish a lot and seems to be training him as a possible successor.
- Only Sane Man: It's pretty obvious that he feels like this around Scott and Stiles a lot of the time.
- Papa Wolf:
- He reacts very badly when someone kidnaps and beats up his son. He probably would've gone after the Argents himself if Stiles had told him the truth.
- Itís likely that harming Scott would set off a Berserk Button, too.
- Parental Substitute: To Scott and later to Malia.
- Reasonable Authority Figure: He is the sheriff.
- Team Dad: Once he figures out about the weird things in Beacon Hills, he joins with Chris in this regard.
- 10-Minute Retirement: Fired when his son's unexplained night-time activities pile up a bit too high. Re-hired after Matt's murder.
- Trademark Favorite Food: Curly fries.
The Sheriff's wife and mother to Stiles, she died of a mysterious, debilitating sickness when Stiles was nine. Nonetheless, she remains a constant presence in their lives.
- Death by Origin Story: Neither Stiles nor his father would be the men they are if Claudia were still alive. Their relationship is notably affected by her demise, leading to both being very protective of the other, deeply afraid of experiencing another such devastating loss.
- The Lost Lenore: The Sheriff still wears his wedding ring, and despite evident chemistry with Melissa, doesn't seem willing to move on from his wife's death to seek out new romance.
Noshiko Yukimura (portrayed by Tamlyn Tomita, Arden Cho [in flashbacks])
ĒI buried the jar deep within the roots of the Nemeton. It was their sacrifice that brought its power back.Ē
Noshiko Yukimura is the centuries old kitsune of legend, and the mother of Kira. Consumed by rage over the loss of her American boyfriend Rhys while detained at a Japanese internment camp during the Second World War, she channeled the powers of the dark kitsune, intending to use its powers to get vengeance. Instead, the dark spirit took over Rhys, giving rise to the Nogitsune.
- Action Mom: She's seen her fair share of action, and doesn't hesitate to step right back into it when she feels the situation calls for it.
- Brought Down to Normal: After using up all her tails during the events of season 3. When she reappears post season-3, it's confirmed she's lost her healing abilities and strength.
- Happily Married: To Kira's father, Ken.
- Interspecies Romance: With Rhys, then with Ken, both humans.
- Last of Her Kind: Mentioned to be the last surviving member of her family.
- Katanas Are Just Better: Used on while fighting the Nogitsune. It is unknown if her katana is magical or if she supplies its magic.
- Kitsune: She is one, although it is unknown what kind.
- Really 900 Years Old: Comes with being a fox spirit. She currently looks like a fairly normal, if very attractive 40+ mother.
- Roaring Rampage of Revenge: Her initial plan back in World War II was to summon the Nogitsune and wreak havoc on those involved in Rhys's death. It...didn't quite go the way she planned.
- Sticky Fingers: Possibly a part of her trickster nature manifesting itself, while imprisoned at Oak Creek she frequently stole food and supplies for her fellow prisoners. She got away with it in part due to her boyfriend looking the other way.
- Wrecked Weapon: Her katana is shattered after she beats the Nogitsune the first time. Decades later, the main characters put it back together.
Ken Yukimura (portrayed by Tom T. Choi)
Kira's father and Beacon Hills High's replacement history teacher (after the Darach's murder of the previous one).
Natalie Martin (portrayed by Susan Walters)
"Of course we're going to do your hair."
Lydia's wealthy and supportive, if slightly distant, mother, who has custody of her after the divorce.
- Good Parents: She genuinely seems to want the best for Lydia.
- Obfuscating Stupidity: She makes a point to appear like a shallow, ditzy socialite, but proves to be genuinely intelligent and competent in a crisis, showing Nerves of Steel when a dangerous virus breaks out in school. Her care for Lydia, and most surprisingly, Coach Finstock, further hint that her superficial exterior is largely a facade.
Lydia's paternal grandmother, who was a banshee like her.
- Bi the Way: Although she obviously had to have some sort of relationship that lead to the conception of Lydia's father, the love of her life was a woman - Maddy, a yacht racer.
- Foreseeing My Death: She predicted her own demise, together with that of many other supernatural beings. Most of the others are saved. She's not.
- Posthumous Character: Died before the start of the series, but proves of great importance to both her granddaughter and the supernatural community of Beacon Hills.
- Psychic Powers: It's unknown how, but she seems to have predicted the events of season 4 and coded a list of people the Benefactor would target.
- Self-Fulfilling Prophecy: The aforementioned list then fell into the Benefactor's hands, which made it far easier for them to place a bounty on the heads of Beacon Hills's supernaturals.
Dr. Geyer (portrayed by Todd Williams)
Dr. Geyer is Liam's stepfather and an administrator at the Beacon Hills Memorial.
- Good Parents: He appears supportive of his stepson, and seems dedicated to help him overcome his rage problems.
- Locked Out of the Loop: Liam insists that his parents can't know about him being a werewolf; because of his anger management issues, he's afraid they'll see him as a monster.
- Remember the New Guy: He and Melissa know each other well, and seem to have been colleagues for a while.
Chris Argent (portrayed by JR Bourne & Max Lloyd Jones)
"Our sons are trained to be soldiers... our daughters to be leaders."
Formerly the chief enforcer of the Argent family, Chris Argent became a protector of innocent humans and supernaturals, after his daughter Allison, then the de facto leader of the Argent family, decided to change the Argent motto, turning them from hunters into guardians. Even after her death, he remains a steady ally to Scott and his friends.
- Anti-Villain: Especially in Season 2, where he functions as the Token Good Team Mate of the Argent family.
- Anti-Hero: he turns into this in Season 3, after his father's mindgames leave him desillusioned in the hunters' cause.
- Arms Dealer: He sells firearms and munitions to law enforcement agencies to conveniently explain why he has so many of them.
- Badass Normal: He has to rely on knowledge, skills and weaponry against often supernatural foes, but when it comes time to kick ass, he really kicks ass.
- Being Evil Sucks: Granted, he does not see himself as evil but the whole hunter thing virtually destroys his family.
- Code Of Honor: Pretty much the only Argent who actually follows it.
- Even Evil Has Standards: In Seasons 1 and 2, toward his father and sister's Kill 'em All attitude regarding wolves. It eventually reaches it's peak when he and Scott team up to stop Gerard.
- Good Parents: He only wants the best for his daughter, even if that means protecting her from her own grandfather, or from dating werewolves.
- The Hunter: One member of a long line of people who have sworn to protect humans from werewolves, going back to the Beast of Gevaudan.
- Knight Templar: In Seasons 1 and 2, Chris genuinely sees his profession as essential to the protection of human beings. He changes his mind after witnessing the destruction his father and sister cause, ultimately culminating in the deaths of his wife and daughter.
- My God, What Have I Done?: Starts feeling this in Season 2, after he helps his wife kill herself and his daughter begins to show signs of becoming a psychopath like his father and sister.
- Never Hurt an Innocent: Essentially what his Code Of Honor is, and yes, for him this also includes Werewolf. As long as the Werewolf hasnít hurt anyone he will not hunt them down.
- Not So Stoic: Sheds tears at his wife's and daughter's deaths.
- Overprotective Dad: Understandably so, considering his daughter is dating a werewolf. Though pulling the kid bodily out of a car and sticking a gun in his face might have been a bit over the line.
- Papa Wolf: Seriously, stay away from his daughter. Especially romantically; he will shoot you.
- Retired Badass: He gives up on the hunting business between seasons 2 and 3, due to the strain on his family.
- The Stoic: Being a Hunter pretty much requires you to be stoic and pragmatic. Even when off the job in Season 3 he still manages to take most of the drastic twists in stride. In "The Divine Move" he says he's always had an ability to suppress his emotions.
- Team Dad: Alongside Sheriff Stilinski, they're both sensible authority figures who look after the teenage protagonists (and sometimes fight alongside them).
- Teeth-Clenched Teamwork: In Seasons 1 and 2, with Scott. In Season 4, his deal with the Calaveras has hints of this.
- Trauma Conga Line: Loses his sister Kate in season 1, has to watch his wife commit suicide and realizes his father is a genocidal monster in Season 2, loses his daughter in Season 3, and finds out his sister isn't dead but has turned into a murderous were jaguar in Season 4. No wonder he's giving up on life.
- Unwitting Pawn: In Season 2, Gerard plays him like a fiddle despite Chris's misgivings about his father's apparent genocidal attitude towards werewolves. But the kicker is that it is only after Chris helps his wife commit suicide because she has been bitten by a werewolf and will soon become one, something Gerard insisted that he do, that Chris learns that Gerard has been planning to become a werewolf himself in order to survive terminal cancer.
Dr. Alan Deaton (portrayed by Seth Gilliam)
"It doesnít necessarily mean itís falling apart. Itís just...changing shape."
Scott's boss at the veterinary clinic, who reveals that he knows all about werewolves once Scott is bitten.
Marin Morrell (portrayed by Bianca Lawson)
"If you're going through hell, then just keep going."
Marin Morrell is a woman of many traits. Aside from being a French teacher and Guidance Counsellor at Beacon Hills High, she is also a resident psychologist at the Eichen House sanatorium, and, as a druid, moonlights as the emissary of the Alpha pack when they are in town. Being an all-around badass runs in her family, as she's Alan Deaton's younger sister.
- Action Girl: She can fight Allison on equal footing.
- All Therapists Are Muggles: Inverted in Lydia's case as she receives counselling from her having no idea her problems are supernatural in origin, and subverted when Stiles tries to edit out the werewolf element of his problems because he doesn't know she's already aware of the supernatural world.
- Badass Bookworm: She can go toe-to-toe with hunters, and she has over 300 hours of field work and a masters degree in behavioral psychology.
- Chuck Cunningham Syndrome: Appears once in Season 3B, and not at all in Season 4.
- Face-Heel Turn: Inverted. She becomes the evil Alpha pack's human liaison in Season 3a, although it's all in the name of balance - this way, she can make sure they get fair representation and cannot do too much damage.
- Good Is Not Nice: There's little doubt she's on the lighter side of things, but rest assured, if you're possessed by an evil spirit and it takes you over, she will kill you.
Braeden (portrayed by Meagan Tandy)
"When you're a human facing off against the supernatural, you need to bend the rules a little bit. I'm gonna teach you how to bend."
Braeden is a young mercenary who frequently gets caught up in werewolf-related action.
- Action Girl: Takes out humans easily and doesn't hesitate to engage in combat even with hunters and dangerous supernaturals.
- Ascended Extra: Originally a mysterious fighter hired by Morrell to save Isaac from the Alpha pack, she seemingly dies at their hands after one episode. When she returns in 3B, she still bears a huge scar from the incident.
- Back-to-Back Badasses: With Derek against the rogue hunters in 'Monstrous.'
- Badass Normal: As a human, she has to rely on weapons and fighting skills, but isn't shy to take on werewolves and even berserkers.
- Beauty Is Never Tarnished: Deucalion may have almost killed her for getting involved in his affairs, but he did make sure not to mar her face.
- Biker Babe: She owns a black motorbike and commonly wears leather.
- Bodyguard Crush: Develops one on Derek, which he reciprocates.
- Brutal Honesty: When Scott asks Braeden if she'd be willing to kill Kate for the right price, she replies that she'd kill him for the right price.
- Dark and Troubled Past: She used to be a U.S.Marshal until the obsession with catching the Desert Wolf forced her to give up her job.
- Good Scars, Evil Scars: Clashing with the Alpha pack left her with a nasty throat scar. It does make her look pretty badass.
- Ms. Fanservice: Shows up in her underwear in episodes of season 4, and she looks good.
- Not Quite Dead: Was presumed dead for the first half of season 3, courtesy of maiming by Deucalion, until she showed up in "More Bad Than Good" to save Derek and Peter from the Calaveras Family.
- Only in It for the Money: She claims that it is her reason for taking on cases, but she's been helping people often enough to hint that this is not quite true.
- Private Military Contractors: She's a mercenary, and pops up in the story because of people paying her.
- Scars Are Forever: She has a nasty throat scar from surviving an Alpha's attack in Season 3A.
Deputy Jordan Parrish (portrayed by Ryan Kelley)

One of Sheriff Stilinski's newest and youngest deputies: he came to Beacon Hills as if by intuition, quickly becoming the Sheriff's right-hand man. Parrish, despite being unaware of the supernatural goings-on of Beacon Hills at least until the end of Season 4
, is helpful to the group through the skills he picked up in the military.
- Adorkable: He tries to appear as a consummate professional at all times, but sometimes, his quirky personality gets the better of him.
Parrish:[reading the deadpool list - he's on it] Well, that's kind of terrifying...What's the number?
Lydia: That's how much you're worth.
Parrish:[indignant] I'm worth five dollars?
Stiles: 5 Million!
Parrish: I only make 40,000 a year! [thoughtful] Maybe I should kill myself.
- Ascended Extra: Deputy Parrish is introduced in season 3B as a Mauve Shirt, but becomes more important in season 4.
- Back-to-Back Badasses: With the Sheriff against the Oni.
- Badass Normal: He's able to hold his own against the Oni admirably. Subverted in Season 4, since he's actually supernatural. He still Fights Like a Normal, though.
- Beauty Is Never Tarnished: Used as a plot point. His hair and nails are fine after his assassin burned him alive, when even beings with a Healing Factor would have lost them.
- Big Damn Heroes: In "Perishable," in which he rescues Stiles and Lydia from a near-death experience.
- Deadpan Snarker: He's almost as good as his boss in this regard.
- Demolitions Expert: His specialty from when he was in the military. It comes in very handy when dealing with one of the Nogitsune's nasty games.
- Die or Fly: Whatever his powers are, they manifested and saved his life after being burnt alive.
- Establishing Character Moment: Amiably chats with Jared about good looks and healthy food, while examining what is presumably a bomb sitting in Jared's lap.
- Fair Cop: Considering he's portrayed by Ryan Kelley, who's a model◊, this trope applies.
- Friend on the Force: To Lydia and Stiles in Season 4; he seems to be their go-to guy whenever talking to the Sheriff might entail too much of a mess.
- Full-Frontal Assault: In "Perishable" to his assassin, as his clothes had burned off.
- I Am What: Didn't know he was supernatural - until someone set him on fire and he survived completely unscathed.
- The Lancer: To Sheriff Stilinski, who tends to be a bit more prone to emotional outbursts.
- Nice Guy: Very much; his friendly nature is why he's great in a crisis (such as bomb removal).
- Pretty Boy: Ryan Kelley is impressively attractive; this gets a mention in dialogue:
Jared:You're a cop? But you're so-
Parrish:Handsome? Thank you. For a second there I thought you were gonna say I look really young.
- Supernatural Gold Eyes: Those appear in a pivotal scene with Chris Argent, possibly indicating that Parrish needs adrenaline to activate his powers.
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 the biological daughter of Peter that no one knew about.
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.
Peter Hale (portrayed by Ian Bohen & Michael Fjordbak)
"I was gonna wait for dramatic flare, but when you look this good, why wait?"
Derek's uncle, the man responsible for biting Scott to begin with, and the original Alpha and Big Bad
of season one. Peter is the one responsible for killing Derek's sister, Laura, in order to become the new Alpha wolf 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.
- Affably Evil: In contrast to his rude, good nephew, Peter is charming and quite pleasant. He gives Allison fashion advice apparently as much because he felt like it as to harass Scott and is rather gracious about Stiles turning down the bite rather than forcing the issue.
- 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, Stiles, and Lydia.
- 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.
- Back from the Dead: Manipulates Lydia from beyond the grave into orchestrating a ritual that returns life to his dead body.
- Big Bad: Peter was the Alpha werewolf who was causing trouble and killing everyone in his path. He also killed Derek's sister, Laura, 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.
- 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.
- Cool Uncle: There are some very subtle hints that he used to be this before the death of his family and him becoming the Evil Uncle seen proper in the series.
- 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 coming back to life, 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: Was Derek's best friend when the latter was in high school before, you know, killing Derek's sister and becoming one of the first season's antagonists.
- Evil Mentor: When they were younger, he had a habit of talking Derek into things that really backfired badly. such as convincing him that his human girlfriend would leave him if he didn't convince someone to turn her into a werewolf.
- Evil Uncle: Peter is uncle to Derek, Laura, and Cora. This doesn't stop him from killing Laura in order to become an Alpha.
- Exposition Beam: By digging his claws into the back of someone's neck, he can grant them his memories. He shows Scott the painful memories of the fire and his long, excruciating recovery.
- Gaslighting: Purposefully weakens Lydia psychologically so that she can bring him back from the dead.
- Handsome Lech: He states in front of everybody that he thinks Scott's mom is gorgeous. Cue Scott looking disgusted and everybody else telling Peter to shut up.
- Heel-Face 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.
- 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, instable 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 doesn't fight often, but when he fights he proves to be quite an impressive fighter.
- Manipulative Bastard: Peter is the epitome of scheming, cunning, manipulative and sadistic. He will use people and brainwash people in order to get others to do what he wants. For most of the first season, Peter had brainwashed Scott and controlled him in order to get Scott to kill all of his friends. Not to mention that he has threatened Stiles, Lydia, Derek and Scott's mother Melissa in order to scare Scott into joining him and Derek so that they could be a pack. For Peter, being in a pack is all about power, dominance and control.
- 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".
- Roaring Rampage of Revenge: He's more than little unhinged by the slaughter of his family.
- 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.
Cora Hale (portrayed by Adelaide Kane)
"You're just a bunch of stupid teenagers running around, thinking you can stop people from getting killed. But, all you do is show up late. All you really do is find the bodies."
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.
- Badass: She can hold her own against Alphas, so she qualifies for this.
- Deadpan Snarker: Seems to be a trademark of her 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, and Deucalion broke into Derek's loft.
- Distaff Counterpart: She is pretty much a younger, less broody Derek in a girl's body.
- Expy: To Erica in some ways: she inherited parts of her storyline, after Gage Golighty left the show between seasons.
- Flat Character: Between finishing out another character's plot and Adelaide Kane leaving the show to become Mary, Queen of Scots on Reign, she sadly doesn't receive much character development.
- Morality Pet: One of Derekís.
- Mysterious Past: There hasn't yet been any explanation of how she survived the fire, how she wound up in South America, what she was doing in the years since, or how she didn't know that Derek, Laura, and Peter were still alive.
- Put on a Bus: She returns to South America after the events of Season 3A.
- Snark-to-Snark Combat: She has to tendency to do this with Stiles, much like her brother.
Talia Hale (portrayed by Alicia Coppola)
Talia is the mother of Derek, Cora, and Laura, and the older sister of Peter. The well-respected Alpha of the Hale pack, she was killed in the Hale Fire, though her claws remain an important MacGuffin
- Animorphism: Notable for being one of very few wolves to avert Wolf Man and shift into an actual wolf, an ability which made her a powerful leader in the werewolf community.
- Big Good: Before her death, all of the nearby werewolf packs respected her wisdom and followed her lead.
- 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.
- Posthumous Character: Talia only appears in flashbacks or in visions induced with her claws.
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)
"I am the Alpha of Alphas. I am the apex of apex predators. I am Death, Destroyer of Worlds! I AM THE DEMON WOLF!!!
The mysterious blind leader of the Alpha pack.
- Big Bad: He's the one in charge of the pack.
- Chewing the Scenery: To the point where he cracks the lenses of his sunglasses with his eyes during a speech.
- Eye Scream: Had his eyes gouged out by Gerard, who jammed two flashbang arrows into them.
- Face-Heel Turn: In "Visionary", Deucalion appeared to be a level-headed, decent guy before Gerard Argent jammed a couple of flashbang arrows into his eyes, blinding him. Now that his sight has been restored by Jennifer/the Darach—and his life was spared by Scott and Derek—it's unclear whether he'll have a Heel-Face Turn.
- Handicapped Badass: Heís functionally blind, and is still able to beat down Scott and Derek.
- Large Ham: Watch him tell the world what an evil demon wolf he is, and still try to take him seriously afterwards.
- Manipulative Bastard: He killed Ennis to gain more power after the latter was expected to survive his fight with Derek, and didnít tell Kali, Aiden, or Ethan about this. Naturally, the trio is now out for Derekís blood.
- 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 heíd 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)
"This is me being gentle."
Graceful and deadly, Kali stands as Deucalion's right hand within the Alpha Pack.
- Character Death: Gets killed by the Darach for mutilating and leaving her for dead when she was still Kali's emissary.
- Dark Action Girl: Action enough to take down Derek and impale him with one of his own pipes, 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.
- 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.
- 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.
Ennis (portrayed by Brian Patrick Wade)
"I'm an Alpha."
Ennis is the first of the Alpha Pack Scott runs into 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.
- 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 didnít take the bite and died, prompting Derekís change from an goofy teenager into a brooding adult. Derek takes a particular dislike against him as a result.
- Jerkass: Heís been nothing but a pompous ass ever since his introduction.
- Smug Super: Lords his status over Scott before getting out-Alpha'd by Derek.
Aiden and Ethan (portrayed by Max and Charlie Carver)
Left: Aiden; Right: Ethan
"Ethan, I always forget.. How many bones are there in the human body?"\\
"I don't know, let's count.
The twins, Ethan and Aiden, are first introduced chasing down Isaac like hounds after a fox, but quickly make a splash by enrolling at Beacon Hills High and setting their sights on Lydia and Danny in order to get to Scott.
Satomi Ito (portrayed by Lily Mariye)
"Three things cannot be long hidden: the sun, the moon, the truth."
A beta werewolf and Noshiko's fellow prisoner in Oak Creek. Between World War II and the present day she became an Alpha, and seemed to be on friendly terms with Talia Hale.
- Badass Grandma: She is the oldest werewolf seen, but greets Deaton with a playful sparring and takes out professional assassins with ease.
- Cultured Badass: Taught herself to control her werewolf powers through playing Go.
- Fire-Forged Friends: With Noshiko, due to battling the nogitsune in the 1940s.
- The Obi-Wan: 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.
- Warrior Poet: Her Buddhist beliefs and philosophical outlook helped her master werewolf rage and develop techniques to avoid discovery.
Brett Talbot (portrayed by Cody Saintgnue)
A young beta in Satomi's pack and rival Lacrosse player from Liam's former school. He does not like Liam overly much.
- Big Brother Instinct: Protects the younger werewolf girl Lori from hunters, to the point where he puts 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.
- Jerk Jock: He is this mostly to Liam, but in general he behaves quite cocky and arrogant on an 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/Stealth Pun: His last name, Talbot, is a reference to Lawrence Talbot, the original Wolfman. Brett, of course, is a werewolf.
- Mr. Fanservice: changes shirts on his first appearance, to the approval of Mason and the audience.
- The Rival: to Liam, in general, and relating to Lacrosse in particular.
General hunter tropes:
- Badass Family: All hunter groups are lead by a central family, which is in turn lead by a matriarch, usually the eldest daughter or the wife of the eldest son.
- Code Of Honor: The traditional Hunter's Code was coined by the Argent family, who apparently were the first organised werewolf hunters: We Hunt Those Who Hunt Us. Allison Argent later decided to turn her family into guardians of innocents both human and supernatural and changed their code to "We Protect Those Who Cannot Protect Themselves." Chris Argent follows the code of his daughter, while other hunters follow the former Argent Code.
- Cold-Blooded Torture: One of their most common "interrogation techniques" when it comes to werewolves. According to Chris, it was also used to "test" werewolf stamina and healing properties.
- Meaningful Name: Both hunter families we've met so far have Names to Run Away From Really Fast: Argent means silver in French (and the Argents are the reason werewolves are said to be vulnerable to silver), while calavera is "skull" in Spanish.
- He Who Fights Monsters: A lot of the hunters seen are considerably violent and often more brutal than the creatures they fight.
- The Hunter: They are werewolf hunters and they are very thorough.
- Knight Templar: They are convinced they are protecting the normal human world from supernatural threats, to the point where they don't really pay attention if what they hunt really is a threat.
- Well-Intentioned Extremist: Most of them truly want to protect people, or least think they do.
The Argent family
The Argents are a noble family of werewolf hunters, with a tradition that goes back to 18th century France. Their US American branch is currently in shambles, after the death of the last two family leaders.
Victoria Argent (portrayed by Eaddy Mays)
"So long as you stay strong, we won't have to kill a sixteen-year-old boy."
The matriarch of the Argent family
, Chris' wife and Allison's mother. Despite her ice-cold demeanour and harsh personality, she loves her husband and daughter and feels very protective of Allison especially.
- The Baroness: While she may not be a hunter herself, as the matriarch of the family, she is their official leader.
- Disproportionate Retribution: She implies to Scott that she'll have him castrated (see Freudian Threat) if she founds out that he and Allison are sleeping together. When she actually catches them kissing, she sets out to kill him.
- Driven to Suicide: After being bitten by Derek, she impales herself with a knife right as she begins transforming into a wolf on a full moon.
- The Dragon: Even though she was the overall leader of the hunters, she answers to Gerard.
- Evil Matriarch: Tries to murder Scott and make it look like an accident for having sex with her daughter.
- Freudian Threat: Asks Scott if he's sleeping with her daughter while sharping a fresh pencil to a stump.
- Fur and Loathing: Frequently seen in a fur coat when out in public. Given her family's proclivities, the symbolism is kind of creepy if you think about it for too long.
- Karmic Transformation: Gets bitten by Derek in self-defense, and is in the process of turning into what she hates the most.
- Laser-Guided Karma: Right after she attempts (and fails) to kill Scott, she is bitten by Derek.
- Mama Bear: Have sex with her daughter? Hope you like a slow death by wolfsbane vapour.
- Power Hair: Victoria has hair shorn even shorter than Hilary Clinton's, very controlled (just like her).
- Principles Zealot: Actually commits suicide rather than become a werewolf, as this is what hunters are required to do.
- Silk Hiding Steel: Barely hiding, but she switches from offering cookies to ordering murders to complaining about academic standards dropping to torturing people on a dime.
Kate Argent (portrayed by Jill Wagner)
"You don't have to be psychotic to be a killer. You just... need a reason and even then, sometimes... You can surprise yourself."
Allison's beautiful but genocidal aunt, who refuses to abide by the Hunter's Code that most of the Argents follow. After she's revealed to be the one who burned down the Hale house, Peter murders her in cold blood, setting up for a far more vicious adversary in season two....Except, she never actually died. She did become a were-jaguar, as was revealed in the final scene of Season Three.
Gerard Argent (portrayed by Michael Hogan)
"No Code. Not anymore."
Allison's grandfather and father to Chris and Kate, who refuses to follow the Code. After Kate is slain, he begins leading a genocide against all any and all werewolves within Beacon Hills, manipulating multiple people to do it. This puts him into conflict with Chris, who notices that Allison is beginning to fall under his sway as well.
A hunter family based in Mexico, the Calaveras view Scott and his pack with suspicion, but as strict followers of the Hunter's Code, they'll leave them alone as long as they prove to live peacefully with humans. They are sometimes reluctant allies and even function as The Cavalry
in one memorable occasion.
Araya Calavera (portrayed by Ivonne Coll)
"Severo? Show them how the Calaveras negotiate."
The current leader of the Calavera family, and a formidable, but ultimately fair woman.
Severo Calavera (portrayed by Ivo Nandi)
"Where is the She-Wolf?"
Severo is Araya's right-hand man, who follows her orders unquestioningly. It's unclear if he's her son, nephew, or much younger brother.
- Foil: He occupies the same role in his family as Chris Argent did for the Argents, but seems perfectly happy to follow orders without possessing Chris' conscience and sense of morals.
- Meaningful Name: Severo means strict. It's hard to imagine him smiling.
- Number Two: To the Calavera's leader, Araya.
- Perpetual Frowner: Severo seems to be constantly irritated.
- The Quiet One: He doesn't talk much, leading to his rather bland quote.
Eichen House Residents
Brunski (portrayed by Aaron Hendry)
An orderly at Eichen House who loves his job, mostly because it allows him to tazer, restrain, and sedate people. As it turns out, he's also a serial killer.
- Alone with the Psycho: Gets nervous when Stiles and Lydia show up in "Perishable", since he thinks they are onto him, leading to the trope.
- Ax-Crazy: Either the reason or the result of frequently murdering people.
- Blood from the Mouth: After Parrish shoots him.
- The Bully: He loves hurting patients when they misbehave. Apparently used to be this even back at school, where he tormented Bobby Finstock. In "Insatiable", Coach manages to finally take revenge.
- Casting Gag: Aaron Hendry is well-versed in playing obnoxious villains on Teen Wolf: in Season 3B he also played one version of the Nogitsune.
- The Dragon: He does all the legwork for The Benefactor.
- Jerkass: Even without the serial killing, Brunski would be a genuinely unpleasant person.
- Orderlies Are Creeps: Turned Up to Eleven when he confronts Stiles and Lydia in "Perishable".
- Sadist: Makes Lydia listen to her grandmother's last breaths. Which he taped. While he murdered her.
- Serial Killer: He's not murdering people, he is helping them.
Meredith Walker (portayed by Maya Eshet)
"I want to help."
Another banshee first seen in "Echo House." Her powers and Lorraine Martin's unfortunate experiments
have turned her mentally unstable, forcing her to live in Eichen House. She has no living family.
- Beware the Silly Ones: Meredith is very odd, but she's not to be underestimated. Especially when it comes to setting people up to be murdered.
- Broken Bird: From the start, she was a shy and fragile person, and hearing the dead probably didn't help much. Then Lorraine tried to help her access her powers, putting her into a coma. And then she met Peter.
- Cloud Cuckoolander: Her more, let's say, eccentric habits regularly drive Lydia up the wall.
- Driven to Suicide: Supposedly took her own life after Lydia's interrogation drove her to do so. Subverted; she somehow faked it.
- Mad Oracle: Her hints are often so enigmatic as to be totally useless.
- Medicate The Medium: In 3B, Meredith is introduced as a patient at the Eichen House asylum, institutionalized because she hears voices and won't stop screaming. Turns out she's a banshee, like Lydia.
- A Mind Is a Terrible Thing to Read: Meredith had to spend several months psychically connected to Peter Hale as he was going insane. Given how her mindset changed after that, it borders on Mind Rape.
- My God, What Have I Done?: When she snaps out of enough to realize what she did by creating the deadpool, is genuinely horrified by her actions.
- The Ophelia: It's safe to say that Lorraine Martin inadvertedly drove her to madness.Lydia feels really bad about it.
- Social Darwinist: See Well-Intentioned Extremist below.
- Well-Intentioned Extremist: She is this to a scary degree, believing that all "weak" supernaturals need to be wiped out to let Peter Hale remake the supernatural world in his image.
Dr. Vallack (portrayed by Steven Brand)
A patient locked away in Eichen House's super secret Level 6 for especially dangerous supernaturals, Vallack is sought out by Deaton for information. He is generally helpful, but has the tendency to turn people who talk to him into living vegetables.
- Evil Brit: He does have a very posh British accent, as befits a possibly villainous psychic.
- Expy: A polite, yet unsettling high security prisoner with an accent and a potentially dark past, whom a main character seeks out for help, having been warned that the man they'll visit will try to get into their head: Dr. Vallack is a supernatural version of Hannibal Lecter. His introductory scene is even written and filmed as an homage to Anthony Hopkins' iconic first appearance as Lecter in The Silence of the Lambs.
- Faux Affably Evil: Dr. Vallack is polite and soft-spoken, but seems to enjoy the negative effect his powers have on other people.
- A Mind Is a Terrible Thing to Read: He seems able to put at least non-supernatural beings into a coma by opening his mind to them.
- The Omniscient: Vallack's powers allow him to know a lot more than a man locked up in a cell and kept from outside contact usually could.
- Pineal Weirdness: The pineal gland is traditionally believed to be the seat of the third eye. Vallack's third eye is positioned exactly where the pineal gland is commonly situated.
- Psychic Powers: He seems to be clairvoyant, knowing things like Kate's plans without leaving his cell. Since he guessed what Deaton wanted to know before Deaton could say it, he also seems to be a mind reader. Finally, he is able to convey knowledge to others by showing it to them mentally.
- Third Eye: He has one in place of his pineal gland. He drilled a hole into his forehead so people can look into it.
Mysterious Supernatural Antagonists
Each season includes at least one major supernatural antagonist whose identity is left a mystery for several episodes. If the monster turns out to be an established character, the entries below cover the portrayal of the monster before The Reveal
The Beacon Hills Alpha
The Beacon Hills Alpha is the one responsible for killing Laura Hale, turning Scott into a werewolf, and causing murder and mayhem throughout Season 1. Late in the season, the protagonists discover that the Alpha is actually Peter Hale
- Obviously Evil: Lampshaded by Stiles, who points out after The Reveal that his clichť villainous traits (red eyes, fangs, turning into a wolf in general) to wryly refute his claim that he's "not the bad guy".
- Red Eyes, Take Warning: An innate trait of every Alpha, made more sinister by his actions.
The Kanima is a murderous reptilian creature with a prehensile tail and a paralytic poison on its claws. Discovering its motives is one of the main arcs of Season 2. In its human form, the Kanima is Jackson Whittemore
- Brainwashed and Crazy: The Kanima seeks a Master to control him and everything that he does. Over the course of Season 2, it is controlled by Matt and Gerard, both of whom used the Kanima to murder and slaughter innocents.
- The Heavy: For the majority of the second season, both the werewolves and the hunters can agree that the Kanima is the main threat they both need to deal with.
- Implacable Man: As the Kanima. Chris Argent shot him, Derek Hale slit his throat open, and Allison Argent planted an arrow in his skull... all for naught.
- Love Redeems: What do you know, it's the Kanima's weakness.
- Reptiles Are Abhorrent: The only major reptile in the cast, and it's a villainous lizardlike creature that murders people at its master's behest.
The Darach is a dark druid who ritually sacrifices victims to gain power and is one of the main villains of the first half of Season 3. The public identity of the Darach is Jennifer Blake
- Human Sacrifice: The main reason for its villainy. It sacrificed all those people in an attempt to defeat the Alpha pack.
- Leave No Witnesses: The Darach attempts to kill both Danny and Lydia, not as sacrifices, but because they had uncovered too much crucial information. It is also implied that Mr. Harris was chosen as a sacrifice not only because of his military background, but because he was complicit in what was going on and might reveal something.
- Rule of Three: Three healers, three warriors, three virgins, three guardians...
- Serial Killer: Killed their victims in ritual sacrifices.
- Well-Intentioned Extremist: The Darach has a pretty good motivation for their behaviour. after Kali killed their pack, leaving her severely injured, she genuinely believes that the Alpha Pack are a danger to everyone and need to be stopped at all costs. Too bad they resort to human sacrifice to achieve their ends.
The Oni are demons who appear as humanoid warriors with masks and glowing eyes. In the second half of Season 3, they start attacking people in Beacon Hills, looking for the Nogitsune
- Casting a Shadow: Can appear and disappear with ease due to turning into black smoke. This comes with the downside of not being able to operate in daylight.
- Hero Killer: One of them is responsible for the death of Allison, although the Nogitsune was controlling them.
- Glowing Eyes of Doom: Their eyes glow behind the mask.
- Implacable Man: According to Silverfinger, the Oni are not fought but instead endured, as fighting them would be pointless due to how powerful they are.
- Logical Weakness: Daylight, due to being associated with demons and the night.
- Malevolent Masked Men: How they appear to the characters: they wear grotesque masks (similar to Japanese Hannya) and are extremely dangerous fighters.
- True Neutral: Noted In-Universe to be this — they have no motivations or sense of good or evil, only that of whoever's controlling them.
- The Voiceless: They don't speak, only follow the commands of their leader.
- Weaksauce Weakness: They're vulnerable to pure silver.
"Chaos has come again."
The Nogitsune is a Void kitsune, a trickster spirit that feeds on chaos and pain. Unravelling its plans is the primary arc of the second half of Season 3. The host of the Nogitsune is Stiles
, at least for a time.
A particularly creepy kind of supernatural fighter, they wear bear skulls and ribcages, and are virtually unstoppable. In contrast to the berserkrs of Norse legend they cannot snap out of their fighting mood, and they have a boss, whom they follow without question: La Loba
, the Bone Woman who is actually Kate Argent.
- And I Must Scream: Per Chris Argent, berserkers who go through the transformation voluntarily slowly lose their humanity, until nothing of their former personality is left. Combine this with the Mind Control aspect of La Loba transforming people like Scott against their will and you get this.
- The Berserker: Played with: They are unstoppable fighters transformed by wearing animal parts, but not enraged or out of control. They also lose their humanity after a while, and cannot drop out of the berserker state anymore. Finally, they have a master whom they obey unquestioningly.
- Brainwashed and Crazy: It is implied that the berserkers didn't become ferocious fighters of their own will, but were forced into their situation by Magic and Mind Control. Invoked with Scott after La Loba forcibly turns him into a berserker.
- Elite Mooks: They are strong, ferocious and unstoppable killing machines, but, aside from Mind Control victim Scott, don't have any personality left.
- Faceless Goons: They are huge guys in bear skeletons fighting for a bad guy: pretty creepy, definitely evil, and not exactly individualists.
- I Know You Are In There Somewhere Fight: If they haven't been transformed for long, there is a small chance of snapping them out of their state. Liam tries it with Scott and succeeds.
- Super Toughness: Katanas faze them as little as bullets or ordinary werewolf strength. You can kill them only by supernatural means - or by blowing them up.
- Malevolent Masked Men: They wear bear skulls as masks, making them instantly recognizable as really evil people.
A mysterious person offering money to have supernaturals assassinated. In addition to the killers they are financing, they are the main antagonist of Season 4. Hidden behind the mask is Meredith Walker, though it's all a little more complicated. The original plan is Peter Hale's
- Anonymous Benefactor: A villainous version. They offer cash to whoever kills off the supernatural creatures on the deadpool.
- The Man Behind the Man: Technically speaking, the Benefactor is four people and one computer: Meredith executed the plan and blackmailed Brunski into helping her, Peter Hale gave Meredith the plan and accidentally donated the financial means, and Lorraine Martin inadvertedly provided the death list and the computer, which connected the list to the money and gave Meredith the means of communicating with the assassins.
- The Unseen: Their communication is restricted to emails, tapes and encrypted lists, so even the hired killers don't know who they are or what they look like.
Professional Killers and other Bad Guys
The Mute (portrayed by Joseph Gatt)
The Mute is an assassin hired by the Benefactor to eliminate the supernatural community of Beacon Hills. This cheerful fellow derives his name from the fact that he has no mouth, the area between his nose and chin being completely covered by skin. He communicates via voice computer.
- An Axe to Grind: He wields a military tomahawk.
- Axe Before Entering: When chasing Sean Walcott, he hacks through the bathroom door with his tomahawk. Serves as a Shout-Out to the famous scene in The Shining.
- Bald of Evil: In addition to having no mouth, he is also bald. It looks quite impressive.
- Character Death: Killed by Peter, who didn't like being axed. Or perhaps didn't want anyone to know that they knew each other.
- Creepy Monotone: He communicates via voice computer, leading to a monotone voice. It becomes creepy due to what he says (see quote above).
- Demolitions Expert: He plans to kill Sheriff Stilinski and Derek using a claymore mine, but the Sheriff figures it out before stuff can actually blow up.
- Good Angel, Bad Angel: Pops up in Scott's Adventures in Comaland dream, representing his killer side. He's the Bad Angel to Liam's Good Angel.
- No Mouth: For some reason, he does not have a mouth. It confuses several people.
- Private Military Contractors: All of his equipment is military, making it likely that he is also this in some form.
- Professional Killer: It's his job and he seems to enjoy it.
An assassin couple the Benefactor invites to take out the supernaturals on their deadpool list. They call themselves The Orphans
because they look like innocent teenagers. They pretend to be new freshmen Garrett and Violet.
