!!'''Scott [=McCall=]''' (portrayed by Tyler Posey)
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/scott-1_5601.jpg]]

->"''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.
----
* AccidentalHero: Since Scott had lycanthropy unexpectedly thrusted upon him, heroism was also thrusted upon him as well. Now that Scott has powers, he seems to thrive to use them to help and save people as much as he can, but all of this heroism is unexpectedly brought onto him.
* ActionHero: Scott is the hero of the series who is always involved in all of the action and fight scenes.
* {{Adorkable}}: Scott has his fair share of cute, dorky moments, especially when he's [[IncrediblyLamePun mooning over]] Allison or goofing around with Stiles.

* ApologisesALot: Scott apologizes so much that it has become a RunningGag in the series.
* {{Badass}}: When his family and friends are threatened, Scott can pull off some pretty awesome things despite being a very young and very new werewolf.
** BadassUnintentional: Scott never planned on being bitten by an Alpha werewolf and go from being a loner, an outcast and a nerd to being a badass werewolf who gained superhuman abilities, strength, popularity and athleticism.
** HeartbrokenBadass: Scott's romance or relationship with Allison hasn't been easy. In the beginning of season 3, Scott mentions how hard it was to not talk to Allison for four months. He says that his relationship with Allison felt like "an open wound".
** TookALevelInBadass: Scott went from a nerdy, asthmatic loner to a tougher, stronger and more badass werewolf with superhuman abilities.
* BattleCouple: Has this relationship off and on again with Allison. Scott, a werewolf often engages in battle alongside, Allison who is a hunter. They both fight crime together and fight for justice.
* BeastAndBeauty: Scott and Allison. Scott is the Beast (a werewolf) and Allison is the Beauty (a beautiful human girl).
* BerserkButton: Do not mess with Scott's friends and family. He will wolf out and he will rage.
* BlessedWithSuck: Scott's powers as a werewolf have managed to cause nothing but trouble for Scott and his everyday life. He has to learn how to control himself and his abilities in order to prevent himself from harming or killing his loved ones. This has been proven to be an ongoing struggle for Scott.
* BloodFromTheMouth: Scott had blood oozing out of his mouth after he was brutally shot by Kate Argent.
* BoyMeetsGirl: Scott meets Allison on her first day of school, and they start dating soon after. Unfortunately, Allison being from a hunter family means that things keep pulling them apart and it's yet to be seen if they can make it work long term.
* BrainwashedAndCrazy: Scott by an Alpha Peter Hale in Night School. Because of this, Scott almost attempts to kill all of his friends including Stiles, Allison, Lydia and Jackson. He snaps out of it pretty quickly, but still...
* CannotTalkToWomen: Scott was initially very awkward with the opposite sex. Even when he first met Allison, he came off as awkward around her and would act rather clumsy around her at first. This eventually changed as he got to know her and he became more comfortable with her afterwards.
* ChickMagnet: Allison Argent, Lydia Martin, Erica Reyes anyone? Scott became more of this after he was bitten by a werewolf. He started to become much more attractive to the opposite sex and he gained more female attention. He gained the attention from all of the known female characters on the show such as Allison, Lydia, and Erica. Allison and Erica were often in competition for Scott's attention and affections. Even Kate Argent (Allison's aunt) found Scott intriguing, charming and attractive. However, Scott has told Erica that she's not his type, though Erica continued to be persistent in her advances towards Scott.
* ChronicHeroSyndrome: Scott suffers from this because he has the constant need to save and protect everyone. If he doesn't, he will end up harbouring guilt.
* ComingOfAgeStory: The series is basically Scott's story of growing up and embracing his destiny as a werewolf with extraordinary abilities.
* CursedWithAwesome: He's not thrilled with being a werewolf, despite the special powers and abilities that come with it.
* CurseThatCures: Scott loses his asthma once bitten. A minor upside to being low man on the FoodChainOfEvil, getting an EnemyWithin and a target of VanHelsingHateCrimes.
* DatingCatwoman: Scott and his romance with Allison. A variation in which he knows she's on the opposing side, or, that her father is anyway.
* DeadpanSnarker: Scott has his moments of sarcasm and quick wit, although the vast majority of it belongs to Stiles.
* DeathGlare: When Scott is angry, Scott will often stare down his opponent in order to intimidate them.
** KubrickStare: Scott will stare down his opponent by tilting his head down and looking up beneath his brows. Normally, Scott does this stare when he is being serious, angry, ready to fight or if he is up against an opponent.
* {{Determinator}}: Once Scott has his mind set on something, he never gives up. He will continue fighting and he is very determined.
* DisappearedDad: His parents are divorced and his mother has full custody. Scott's father is an absentee father and has left Scott, abandoning him.
* DistractedByTheSexy: Scott tends to float off into La-la Land whenever Allison's around or even mentioned.
* DorkKnight: Even though Scott has gained abilities as a werewolf and has become rather heroic, Scott can be rather dorky and socially awkward; the same way he was before he was bitten.
* FairyTaleMotifs: In the Pilot episode (''Wolf Moon''), Scott and his best friend Stiles are out in the woods together trying to find or discover a murder victim's body. Coincidentally, like LittleRedRidingHood, Scott is wearing a bright red hoodie. After Stiles manages to get scared off and escapes, Scott ends up getting lost in the woods. Scott realizes that he has lost his inhaler and wanders around the woods trying to find it but is having no luck. Scott is then suddenly attacked by an [[OurWerewolvesAreDifferent Alpha]] werewolf and he is bitten; forever changing Scott from a normal, human teenage boy to an individual cursed with lycanthropy or werewolf-ism. This is how the story of Teen Wolf began.
* TheFettered: Scott lives by a code of morals and standards. There are just some moral lines that Scott will not cross.
* FlatWhat: Scott's reaction, alongside Jackson, when he discovers that he is being made a co-captain of the lacrosse team with Jackson.
* ForHappiness: This is Scott's motto in regards to why he fights so hard and is always determined to save and protect everyone. Because more than anyone, Scott wants everyone that he cares about to be safe and happy.
* FriendlessBackground: Before being bitten, Scott was a loner and social outcast who didn't have any friends or a large social circle with the exception of Stiles.
* GoodIsNotSoft: Although Scott is TheHero, the good guy and he generally doesn't like to resort to physical violence, he will do so when it is completely necessary. Although he would rather find another way to solve the problem. But if you mess with him or hurt his loved ones, he will not hesitate to kick your ass.
* TheHero: Scott is the hero of the show, as he is the male lead character of the show who's purpose is to protect and save everyone.
* HeroProtagonist: Scott is both the hero and the protagonist of Teen Wolf. Scott is the hero because his primary role is to save and protect everyone. And Scott is also the protagonist because the story centres on him dealing with his lycanthropy.
* HeterosexualLifePartners: Scott and Stiles are both straight, but they love each other as best friends and true companions. They have been through everything together. They will always look out for each other and have each others backs no matter what.
* HormoneAddledTeenager: In season 1 in regards to Allison. Scott seemed to be obsessed with Allison to the point where he would wolf out in arousal by being around her. This has changed though as of season 3, since Scott has become [[CharacterDevelopment significantly more mature and less hormonal.]]
* HotBlooded: Scott is seen to be extremely passionate, especially when it comes to Allison. His passion levels have increased ever since being turned into a wolf as being a werewolf heightens one's feelings and emotions; this includes sexual desire. Also, when Scott gets angry or irritated, he will act very recklessly and impulsively.
* HowDoIShotWeb: He lacks the control of his lycanthropy seen in Derek, who tells him as much.
** DoesNotKnowHisOwnStrength: After being bitten, Scott lacked total control over his own strength.
* HurtingHero: Scott may be the good guy but his life is always happy and easy, right? Wrong. Although Scott goes out of his way to make sure everyone is safe and tries to protect everyone, it sometimes gets to be too hard and tough on Scott. His life is often in danger, his loved ones lives are constantly put in danger and keeping everyone safe seems to take up most of Scott's free time that he never really has time to live a normal and content daily life. Sometimes, Scott has to choose between being alone or putting the ones he loves in serious danger. In "Master Plan", Scott told Stiles that he was back to where he had originally started before he was bitten: no girlfriend, no popularity, failing school, and losing his position as co-captain on the lacrosse team.
* InterspeciesRomance: Scott, who is a werewolf, is in love and in a romantic relationship with Allison, who is a human.
* IDidWhatIHadToDo: Scott did this in season two when [[spoiler: Scott worked for Gerard by joining and spying on Derek's pack in order to gain information to give him, to prevent Gerard from going through with his threat of hurting or killing his mom.]]
* IHaveNoIdeaWhatImDoing: In 2x11, Scott openly admits to Isaac that he thinks that he has no idea what he is doing most of the time, despite the fact that Isaac had just told Scott that he had trusted him and that he always seemed to have good intentions by always wanting to do what is right. See IdiotHero.
* IJustWantToBeNormal[=/=]ReluctantHero: Despite Scott being given either the gift/curse of lycanthropy, which has given him invincibility, Scott still yearns to be a regular, human teenager with the normal life he had before. In the Pilot, when Derek catches Scott in the woods after Scott had changed into a wolf, Derek had told Scott that the bite was a "gift". Scott told Derek that he didn't want the bite. This is why throughout season one, Scott yearned to find a cure for his lycanthropy in order to return back to the regular, normal, asthmatic teenage human he was before.
* IJustWantToBeBadass: Ironically, before Scott was bitten and changed into a werewolf, Scott yearned to be more popular, more attractive and more athletic. He wanted to have more power, dominance, popularity and athleticism while he was a regular human.
* IJustWantToHaveFriends: Before Scott was bitten, Scott was rather socially awkward, self-conscience, a loner and didn't fit in with the popular crowd at his school. He didn't have any friends or a large social circle, except for Stiles. Scott yearned to have many friends beyond just Stiles, who has been his best friend since childhood. Scott eventually gained popularity and confidence (also with the opposite sex) after he was bitten.
* ItsAllMyFault: There are times when Scott feels that everything that is bad that is happening to his friends and family is his fault due to his ties to the supernatural and what he is. Sometimes Scott blames himself for all of the bad supernatural events occurring within Beacon Hills and also, to his immediate inner circle of family and friends.
* ItsNotYouItsMyEnemies: In regards to Scott's relationship with Allison. Because of Scott's role is to save and protect everyone, Scott has many dangers and responsibilities associated with him; the dangers also associated with Scott being a werewolf. Although Scott can accept this and does accept that he has bigger responsibilities, he doesn't want to ever put Allison or any of her family in harms way because of him. At the end of 2x12, Allison breaks up with Scott and Scott accepts it because he realizes that it's better if they are apart then if Allison's life is put in any more danger because of him. Despite this, Scott does tell Allison that he believes that eventually, they will be together, but right now isn't a good time because of all the circumstances surrounding them.
* LeParkour: As a werewolf, Scott is able to easily jump, climb and leap across cars, buildings, walls, obstructions like that of an obstacle course.
* LightswitchSurprise: This happens to Scott more often than any other character on the show. Often, there is almost always a 99.9% chance that if Scott comes into his dark room and turns on the lights, someone will always be sitting in his room creeping in the dark (whether it's Stiles, Derek or Gerard).
** In 1x06, Scott came home, closed the window, turned on the lights and BAM! There was Derek, sitting in a chair expectantly.
* LittleDeadRidingHood: In the Pilot, ''Wolf Moon'', Scott is seen to be wearing a red hoodie. This is a tribute to the classic fairy tale, LittleRedRidingHood. When Scott gets lost in the woods, Scott is unexpectedly bitten by the [[OurWerewolvesAreDifferent Alpha]] werewolf, triggering the beginning of his curse of lycanthropy.
* LivingEmotionalCrutch: Scott is this to Stiles, Derek and even Allison. In "Battlefield", Peter told Derek that Derek needed Scott more than anyone. Stiles has been seen to be rather dependent on Scott, especially when he is faced with emotionally tough times. Allison, although very capable of taking care of herself, seems to be the most happy when she is with Scott. Allison could be seen as using her relationship with Scott to escape the darkness and secrecy of her family and her family legacy as hunters.
* LivingLieDetector: Like all werewolves, Scott has the ability to tell whether or not someone is lying.
* LovableJock: Scott may be a jock (lacrosse player), but he is a likeable jock.
* [[MainCharacters Main Character]]: Scott is the main character of the series because the story focuses on him dealing with his werewolf-ism. Scott is also known as the {{Protagonist}} and TheHero.
* TheMasqueradeWillKillYourDatingLife: This was true early in the first season when Scott was still hiding what he was from Allison. The secrecy was what caused their first break-up. Later on in the series after she knows, there are other issues that effect their relationship.
* MoralityChain: Scott is this to Derek and Isaac, but more Derek. Scott often prevents both Derek and Isaac from acting deviantly and out of control. Since Derek, who can be classified as a NobleDemon, is seen as someone who does many morally questionable things, Scott often brings out the more moral side of Derek and brings out his "better side". It has been noticed that without Scott's influence, Derek will continue to make detrimental and costly mistakes that put others in danger, including himself. It could be possible that because of Scott's refusal to join Derek's pack and be Derek's Beta, Derek has proven to be a rather incompetent and cynical leader who screws up quite a bit.
* MoralityPet: Scott is this to Derek. Scott becomes an important character for Derek in terms of redemption and Derek's humanity. Derek seems to have a soft spot for Scott and will often question things due to Scott's influence. Derek often draws a sense of stability from Scott's influence and presence and Derek most likely sees Scott as a younger brother figure in his life.
* MrFanservice: Scott is attractive and often has his shirt off, exposing his buff chest, abs and arms. This seems to be an ongoing thing in order to impress the female viewers.
* NaiveNewcomer: The circumstances around Scott being turned into a werewolf makes him into this, and it isn't until Derek's arrival and extensive researching on Stiles' part that Scott truly begins to understand how being a werewolf affects his daily life.
-->'''Stiles''': You're so unprepared for this.
* NerdyInhaler: While he was still a regular human, Scott was a social outcast and a loner who suffered from severe asthma conditions. Because of this, he carried an inhaler with him at all times.
* NeverGetsDrunk: It appears 1x08 while Scott was drinking with Stiles, that Scott couldn't get drunk. Although both Scott and Stiles were drinking, Scott didn't get the least bit tipsy, while Stiles got extremely wasted. Scott's inability to be influenced by alcohol could be part of his abilities as a werewolf.
* NiceGuy: Scott is a nice, sweet guy to basically everyone...well, almost everyone.
* NiceJobBreakingItHero: It is easy to understand how Scott could be sympathetic towards [[spoiler: Jackson]], who cannot control his change into the Kanima. But by so vigorously protecting him from being killed by Derek, even though Scott had no plan for how to keep him contained in the long-term, he technically bears some responsibility for all the murders the Kanima subsequently commits, especially of [[spoiler: all those innocent police officers]].
* NobleMaleRoguishMale: Scott has this type of relationship with Derek. Scott is known to be the noble, gentle and more diplomatic in how he approaches things, while Derek appears to be more reckless, impulsive, wild and more prone to violence. Because of Scott and Derek's differences, they often clash.
* NoSocialSkills: Before being bitten, Scott was a loner, socially awkward and unpopular. This took a 180 turn after Scott was bitten and turned into a werewolf; he gained popularity, gained female attention (and a beautiful girlfriend), and became a star athlete (the captain, later co-captain, of the school lacrosse team).
* NotHimself: Scott becomes reckless, irrational, cruel and loses his inhibitions especially when the full moon comes out.
* OnlyFriend: To Stiles, and vice-versa. At least initially neither boy seems to have anyone else they spend time with.
* OrdinaryHighSchoolStudent: Scott fit this trope before he was bitten by a werewolf. Before being bitten, Scott was a normal, human high school student.
* ParentalAbandonment: Like almost every other character on the show, Scott has an absent parent. His father abandoned him and his mother and he could be considered a dead-beat dad.
* PartTimeHero: Scott may want to help, protect and save everyone and make sure everyone is happy and alive, but he also wants a normal life and a sense of normalcy as much as possible.
* ProHumanTranshuman: Scott is a victim of this as a result of being bitten by the Alpha werewolf. Despite what he has become, which is a werewolf capable of great destruction, he still fights to be part of humanity and keep a hold on his human side instead of succumbing to the destructiveness and darkness that comes along with being a werewolf.
** He cares deeply for humans and innocents, even trying to protect the Argents when possible. In contrast Derek is fine offering the "[[BlessedWithSuck gift]]" of Lycanthropy to those who crave it, outcasts, the emotionally damaged and with health problems. Scott is particularly upset at this because of the active hunting werewolves face, making that much more likely the new converts die... Assuming they don't kill someone first.
* RealityEnsues: Scott always [[ShouldntWeBeInSchoolRightNow misses out on school due to being a werewolf]]... which causes him to have terrible grades and risk being held back a year.
* {{Protagonist}}: Scott is the main protagonist of the series as the story centres around him dealing with his lycanthropy.
* TheRival: Scott is this to Jackson for most of the series. After Scott gets bitten, Scott becomes a star athlete on the lacrosse team and gains popularity, robbing Jackson of his status as top lacrosse player and most popular. This causes Jackson to become highly antagonistic towards Scott and vice versa, causing the rivalry between Scott and Jackson to heat up intensely, especially in the first season.
* SaveTheVillain: Scott attempted this in season two [[spoiler: when he tried to save the BigBad, the Kanima aka Jackson. While everyone else, including Derek and Stiles, wanted to kill Jackson, Scott didn't want to kill him and wanted to save him instead.]]
* SecretIdentity: Scott keeps his identity as a werewolf a secret from the public due to the many dangers surrounding him (including werewolf hunters).
* ShirtlessScene: Scott gets these types of scenes frequently throughout the series generally corresponding with shape-shifting.
* ShrinkingViolet: Before being bitten, Scott was extremely shy, a loner and a social outcast. He didn't fit in with the popular crowd and didn't have a large group of friends.
* SociallyAwkwardHero: Although he is capable of bravery, courage and heroism when fighting or battling the bad guy, Scott is still the same clumsy and awkward person he was before he came a werewolf.
* StarCrossedLovers: Scott and Allison are known to be the show's "starcrossed lovers" due to the events, circumstances and obstacles surrounding their relationship. These outside issues often try to tear Scott and Allison apart and prevent them from being together. The biggest obstacle is the fact that Scott is a werwolf who was bitten and turned against his will and Allison, the object of Scott's affection, happens to come from a family that hunt Scott's kind, which are werewolves. This has managed to cause tension surrounding their relationship, often causing the two to part rather frequently throughout the series. Still, they manage to come back together eventually. Scott had even told Allison that he believed that they are fate and that he knows deep down that they will be together some day.
* {{Superhero}}: [[spoiler: According to the producer, Jeff Davis, Scott will become more of this trope in season three when Scott begins to use his powers for good. Jeff also frequently makes comparisons between Scott and Peter Parker / {{Spiderman}}, saying that Teen Wolf is a {{Spiderman}}-type of story.]]
* SuperpowerLottery: After Scott was bitten and cursed with lycanthropy, Scott developed various special powers and abilities.
** SuperStrength: Scott has the ability to carry or lift much heavier objects due to his lycanthropy.
** SuperSpeed: Scott is able to run and move faster than that of a normal regular human.
** SuperReflexes: This ability is similar to super agility. Scott is able to move and react faster to situations than that of a regular human. He is also able to jump and climb things with ease.
** HealingFactor: This is similar to invulnerability. Scott's cuts, gashes, scrapes and wounds will easily heal. If Scott gets shot or stabbed, he will not die and will heal almost immediately.
** {{Shapeshifting}}: Scott has the ability to shape shift between human and werewolf. When the shape shifting happens, Scott's physical appearance starts to change, mostly facially. His eye's become a yellow colour, his face grows hairier, fangs start to appear, his ears become wolf-life, and he grows claws on his fingers. There are some factors that can contribute to Scott shape shifting into a wolf, such as anger, irritation, frustration or even sexual desire. One factor that prevents Scott from shape shifting or "wolfing out" is love, which is his anchor to his humanity.
** SuperSenses: All of Scott's senses such as his sight, smell, taste, touch and hearing have all increased and exceed beyond that of a regular human. With his sight, Scott is able to see things much more clearly and also, see things from a greater distance. With his smell, Scott can smell things much stronger than a human. He is also able to catch distinctive scents and also, smell scents from a reasonable distance. With his hearing, he is able to hear things much clearer and also hear things from a distance. An example of this, was in the Pilot episode, when Scott was sitting in the classroom. He could suddenly hear Allison outside talking on her phone, hearing her entire conversation. With his taste and touch, not much has been explored in regards to these senses of Scott's, but it could be implied that since becoming a werewolf, Scott's sense of taste and touch have improved as well.
** HealingHands: Scott has the ability as a werewolf, to absorb pain and suffering from animals using his hands. This was demonstrated in 2x11 "Battlefield", when the Deaton showed Isaac how to take a dying dog's pain away by placing his hand on the dog and absorbing some of its pain. Isaac was touched by this ability that he possessed; Scott told Isaac that the first time Deaton showed Scott how to use the ability of healing, he cried as well.
** TheEmpath: Like all werewolves, Scott is able to sense the emotions and feelings of others, whether it be sadness, anger, frustration, love, etc. This becomes magnified during a full moon. In 1x08, Scott told Stiles that he was able to feel the emotions of everyone in the classroom. In 1x06, Scott tells Derek that he could sense how the Alpha werewolf was feeling and he told Derek that the Alpha was angry. Derek also told Scott that due to his lycanthropy, he can sense the emotions of others.
* SupernaturalGoldEyes: As a werewolf. In human form, he's got puppyish brown eyes.
* TechnicalPacifist: With Scott being a werewolf, violence often comes along with it. Scott is very capable of killing when he has to, but Scott does not take the ending of one's life lightly whatsoever. He believes that killing shouldn't be the first option. However, if Scott is given the option of either killing the villain/anti-hero or not killing the villain/anti-hero, he will not kill the villain/anti-hero. An example of this is with Jackson as the Kanima. Despite the fact that Jackson was killing innocents, Scott still didn't want to kill him and instead, opted to find a way to save him.
* ThePowerOfLove: Due to Scott's love for her, Allison has the ability to keep Scott human and prevent him from wolfing out. Allison has been described as Scott's humanity or his anchor into keeping his humanity.
* ThoseTwoGuys: Scott and Stiles fit this trope. Scott and Stiles have somewhat different personalities that complement each other. While Scott is more reckless and impulsive, Stiles is more logical and practical.
* ThouShaltNotKill: Scott believes that no matter how good or bad someone is, even if they are a monster, killing them shouldn't be the first option.
* TookALevelInBadass: Scott became more badass, capable and athletic after he was bitten and turned into a werewolf.
* UnwittingPawn: Scott in season two [[spoiler: succeeded in stopping Gerard from becoming a werewolf and killing everyone, but Scott may have only furthered Gerard's desire for revenge against everyone. By Scott helping Gerard and aligning with him in order to protect his mother and everyone else, only to outsmart Gerard, may have made Gerard possibly more vengeful than ever.]]
* WakeUpGoToSchoolSaveTheWorld: This is basically Scott's life as a werewolf, and it is not at all easy.
* WithGreatPowerComesGreatPerks: When Scott is turned into a wolf and gains powers and abilities, Scott doesn't really use his powers and abilities for deep, meaningful purposes. Instead, Scott kind of uses his new found abilities for selfish reasons. He often used his powers on the lacrosse field in order to win games and have power and dominance over his fellow teammates. At first, Scott primarily used his newfound werewolfism and the powers that came along with it to improve his confidence and his everyday life. However, in season two and in season three, [[spoiler: Scott starts using his powers and abilities to save and help others, bringing Scott into more of a hero mindset.]]
* VirusVictimSymptoms: Scott fits this trope, because after Scott was bitten, Scott began to change in every way possible in terms of behaviour, personality, and physical appearance. The worst side of Scott comes out during the full moon, where his behaviour becomes irrational, aggressive, cruel and out of control. These are all the aftermath symptoms of a viral transformation (being bitten by the Alpha werewolf).
* ViralTransformation: Scott became a werewolf through being bitten by the Alpha werewolf. This could be considered to be a viral transformation.
* WolfMan: Scott develops wolf life features when he starts to transform. He is still a humanoid but has wolf-like features.

!!Stiles Stilinski (portrayed by Dylan O'Brien)
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/stiles-1_2282.jpg]]

->"''I'm 147 pounds of pale skin and fragile bone. Sarcasm is my only defense.''"

Stiles is Scott's best (and only, initially) 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.
----
* AManIsNotAVirgin: Aversion. This actually becomes a plot point in season 3.
* ActionSurvivor: Stiles, who's an untrained human among werewolves and hunters.
* {{Adorkable}}: Stiles is quite awkward and can politely be described best as 'offbeat', but manages to be endearing and amusing throughout.
* AfraidOfNeedles: Stiles passes out at the sight of needles, as evidenced when he saw Scott getting a tattoo.
* AlliterativeName: Stiles first and last name both start with the same sound and the same letter: S.
* AlwaysSomeoneBetter: Feels this way in regards to both Scott and Jackson. For Scott it's the fact that he's a werewolf. For Jackson it's that Jackson is first in Lydia's heart.
* AmbiguouslyBi: Is 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 [[ItMakesSenseInContext finds him at a gay bar]], he tells his dad that he "could be [gay]." He also seems almost disappointed when Danny's offer to sleep with him turns out to be a joke.
* AttentionDeficitOohShiny: Averted. Stiles has ADHD according to WordOfGod, but it mainly manifests in impulsive decisions and body language.
* {{Badass}}: Stiles may be human but he can keep up with the supernatural beings around him.
** BadassNormal: The boy rushed into harm's way just to pelt Peter with a molotov cocktail in the season 1 finale. That takes ''balls of steel.''
** BadassInDistress: Although Stiles is capable of taking care of himself, there are instances when Stiles needs a little saving too, namely by his werewolf best friend, Scott.
* [[BeautyMark Beauty Marks]]: Stiles has distinctive moles and beauty marks all over his face. In close up shots, the beauty marks or moles are quite noticeable.
* BrainsAndBrawn: Stiles is the Brains to Scott's Brawn.
* BuffySpeak: Stiles is by far the worst offender during his MotorMouth tangents. Once Stiles gets going, he doesn't realize how he is speaking.
* CharacterDevelopment: His EstablishingCharacterMoment was [[PluckyComicRelief falling off of Scott's roof]], by the season 1 finale he [[spoiler: sets fire to the Alpha]]
** Season two sees him in therapy with Ms Morell, [[spoiler: beat up by Gerard, and hitting the Kanima with his Jeep]]
* TheConscience: Stiles fits this trope in regards to Scott. Stiles often helps Scott to keep a hold onto his humanity and has helped him with his lycanthropy, especially after he was bitten and turned. Stiles is always there for Scott to make sure that he doesn't lose control and that he doesn't hurt anyone around him.
* TheConfidant: Despite being a normal human, he's keeping many [[SecretKeeper secrets]] of the wolfy and scaly variety for a whole lot of people.
* ConstantlyCurious: Stiles is always curious about everything that goes on around him. His curiosity does end up getting Stiles into quite a bit of trouble though.
* {{Determinator}}: Once Stiles has a mission, he never gives up. He is extremely determined. Even though Scott is a werewolf who has put Stiles life at risk a few times, Stiles still sticks by Scott and is always determined to stand by him no matter what.
** [[spoiler: 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.]]
** [[spoiler: Stiles made his way across the police station - which was, at the time, a battleground between the Argents, the Kanima, and the werewolves - in order to reach and/or rescue his father. Crawling on the ground; on his belly; with the majority of his body still paralyzed from the Kanima's venom.]]
* DidIJustSayThatOutLoud: Stiles has a habit of saying what he is really thinking and feeling when it isn't always the best or most appropriate time. The primary cause of Stiles big mouth is his MotorMouth. Once Stiles gets going, he can't stop and he ends up saying something that can lead to many awkward (yet funny) moments.
* DidYouJustFlipOffCthulhu: Stiles has a habit of pissing off insanely powerful creatures and people who already don't like him.
* DistressedDude: Although Stiles is a very capable sidekick, sometimes he needs quite a bit of saving too. More than any other character, Stiles has been harassed, hit, beaten and even kidnapped throughout the series. An example of this is in 2x12, when Gerard kidnapped Stiles and beat him up in order to get back at Scott.
* DoggedNiceGuy: For Lydia, who's unaware he exists, doesn't care when she finds out he does, and is in love with Jackson.
* EnterStageWindow: His common entry into the [=McCall=] residence... before he has a key made.
* AFriendInNeed: He sticks by Scott even after he nearly killed Stiles during one of his transformations.
* GeniusDitz: Despite his serious troubles with ADHD, including writing an essay on circumcision on his ''economics'' midterm, he has perfect grades, is an amazing researcher and investigator, and he and Lydia are probably tied for the smartest characters on the show.
* GenreSavvy: 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 [[DistractedByTheSexy 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 [[UpToEleven EVERY POSSIBLE WEB PAGE]] on werewolves.
** Derek parodies this when he talks to Scott in the second episode.
--> '''Derek:''' Do you think your little buddy, Stiles, [[LampshadeHanging can just look up werewolves and now you've got all the answers?]]
** In the sixth episode, Stiles tries to do experiments with Scott's heart-rate by throwing Lacrosse balls at him.
* HeterosexualLifePartners: Stiles is this with Scott. They are inseparable and have been through everything together, good and bad. Stiles and Scott often go through withdrawls if they are separated for too long.
* HollywoodNerd: Stiles may be somewhat of a nerd or a geek who has brains and smarts, but he's also an attractive one with a bit of charm.
* LastNameBasis: 'Stiles' Stilinski is only Stiles. Even his father calls him Stiles.
* MeaningfulName: A "stile" is literally a means of passage over obstacles. Stiles himself manages to help pretty much everyone during the course of the series.
* MissingMom: She died. Slowly, according to WordOfGod. He blames himself for her death, if his hallucination of his father in Season 2 is anything to go by.
* MissionControl: He’s the most likely person of the heroes to not be involved in a fight; he instead uses his intellect to help the more action-oriented heroes (IE: Scott, Allison, Derek, Isaac, and Cora) figure out where to go so ‘’they’’ can fight.
* MotorMouth: 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.
* MuggleBestFriend: To Scott. Aside from his brain and knowledge of supernatural lore, Stiles is completely and utterly human. And unlike Allison, he also has no combat training, either.
* NiceGuy: Almost as much as Scott
* NightmareFetishist: Shades of this color Stiles at times. The series is set in motion by him 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!"
* NoSocialSkills: 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.
* NotNowKiddo: In "Night School", while the rest of the group are barricading the door from the Alpha, Stiles is trying to point out [[AbsurdlyIneffectiveBarricade the 20-foot windows]].
* OnlyFriend: To Scott, at least initially. 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.
* OnlyKnownByTheirNickname: His first name is apparently enough to reduce Coach Finstock to giggles and claim that such a name should 'amount to child abuse'.
* OnlySaneMan: 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!"
* OpenMouthInsertFoot: Due to Stiles MotorMouth, Stiles has a habit of saying the wrong thing at the wrong time, leading to lots of awkwardness.
* OralFixationFixation: 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.
* OvershadowedByAwesome: By the end of season 2, definitely. He knows that he's the most vulnerable of the group, being the only one without combat training or some form of supernatural power.
* PluckyComicRelief: Stiles is known to be '''THE''' comic relief or humour of the show. He's known to be very witty and funny and has great comedic timing.
* PragmaticHero: Stiles is probably one of the most logical and pragmatic characters on the show. Comes with being a BadassBookworm and the brainiac of the core group.
* RealityEnsues: Stiles always gets up to some serious shenanigans [[spoiler: like stealing police property and kidnapping one of his fellow students... [[NiceJobBreakingItHero which then causes his dad, the town Sheriff, to lose his job.]]]]
* TheReliableOne: Stiles is the one that is very reliable and is always there for his friends and family whenever they need him.
* TheScapeGoat: To Adrian Harris, the chemistry teacher. For some reason, he seems to have a strong dislike for Stiles and often humiliates him in front of the entire class.
* SecretKeeper: In the beginning, Stiles was the first and only one (besides Derek) to know that Scott was a werewolf who was cursed with lycanthropy.
* ShipperOnDeck: In the beginning, Stiles was a Scott/Allison shipper.
* {{Sidekick}}: Stiles is this to Scott. Stiles often assists or helps Scott during a mission, plan or battle. Stiles often refers to being the {{Robin}} to Scott's {{Batman}}.
* TheSmartGuy: He even specifically referred to himself as being this during an episode. He tends to share the role in the group with Lydia though as she's smarter than he is.
* SmartPeopleKnowLatin: He's working on it.
* SurvivorGuilt: In his hallucination, Stiles reveals that he feels guilty for his mother's death and believes that his father blames him.
* TeenGenius: Stiles is a teenager whom is seen to be extremely intelligent and bright. He often comes up with the answer to many mysterious questions which are asked. Stiles was the first to realize that Scott was cursed with lycanthropy after Scott was bitten.
* ThatCameOutWrong: Numerous instances, but Stiles is always making them.
* TrademarkFavouriteFood: Stiles favourite food are curly fries. Coincidentally, he seems to share this favourite food with his father, Sheriff Stilinski.
* TrueCompanions: Stiles is this with Scott. Scott is Stiles best friend since childhood and they do everything together. They are inseparable and are like two peas in a pod.
* UndyingLoyalty: Stiles fits this trope in regards to his friends and family, but especially to Scott. Despite Scott being a werewolf that brings much unwanted drama into Stiles life, Stiles still manages to stand by Scott no matter what.
* UnfazedEveryman: 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.
* WakeUpGoToSchoolSaveTheWorld: Much like Scott, Allison and Isaac. Stiles may not be a werewolf but he is always involved in the action.
* WeirdnessMagnet: Stiles often laments his tendency to be a human form of this, especially due to the fact that he is a human surrounded by the supernatural.

!!Derek Hale (portrayed by Tyler Hoechlin)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/derek-1_6259.jpg]]

->"''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.
----

* AntiHero: Although Derek has good intentions, he does morally questionable things to achieve his well-intentioned goals.
* AuthorityEqualsAsskicking: Derek is an Alpha, therefore, 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.
* {{Badass}}: he is a strong, capable fighter, even more so after becoming the Alpha werewolf in town at the end of Season One.
* BigDamnHeroes: Tends to do this for most of the other heroes.
* BigBrotherMentor: Derek is this to Scott and then Isaac, Boyd and Erica later on. As the oldest and most experienced werewolf, Derek looks out for and protects Scott and the younger wolves as much as he can giving pointers on how to use their powers and survive.
* BloodFromTheMouth: Derek, after getting claw-stabbed in the back by an Alpha Peter Hale.
* BlueAndOrangeMorality: 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.
* BrutalHonesty: 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.
* ButtMonkey: 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.
* CanNotSpitItOut: 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 Argent's hunt werewolves." would have literally taken seconds to get out the very first time he met Scott.
* CoolCar: For someone who seems to be poor and homeless, Derek sure owns a nice, expensive car. Derek drives a black 2010 Chevrolet Camaro.
* CynicalMentor: 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.
* TheComicallySerious: His glaring or hostile reactions to other people's actions, especially Stiles', are often much funnier than the initial joke.
* TheCynic: 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, TheIdealist. Although 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.
* DarkAndTroubledPast: Several years before the start of the show, his whole family was murdered by hunters, specifically Kate, who seduced him to find out the family's weak spots. Derek obviously didn't take it too well. [[spoiler: It’s also revealed that his first love was bitten by Ennis, leading to him turning from a [[CheerfulChild happy teenager]] into the emotionally detached person he is today.
* DarkIsNotEvil: Though his methods are often questionable, especially to humans, his motives most commonly amount to protecting people and righting his own wrongdoings.
* DesperatelyCravesAffection: The fact that Derek was desperately trying to connect with Scott in season's one and two 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.
* DestructiveRomance: Derek had this with Kate Argent. His relationship with her not only destroyed him as a person, but also got his entire family killed.
* DontSneakUpOnMeLikeThat: Derek does this to people all the time. Stiles is the most common recipient, since he's human and all.
* DrillSergeantNasty: 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.
* FaceHeelRevolvingDoor: 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.
* GoodIsNotNice: 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. He's just ''really'' stand-offish.
* GoodThingYouCanHeal: Regarding himself and any other werewolf.
** 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".
* [[SheIsAllGrownUp He 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. [[FridgeHorror It also implies he wasn't what could be considered]] [[{{Squick}} "grown up"]] [[FridgeHorror when she was sexually manipulating him]].
* HeroWithBadPublicity: He protects Beacon Hills from supernatural threats like the Kanima but to the majority of the residents he is a vicious criminal.
* HeroicBSOD: 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 [[spoiler: by Ennis]], and her body rejects it, causing both her death and the beginning of his frosty personality shift.
* HisStoryRepeatsItself: 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 of this very trope.
* IneffectualDeathThreats: Derek is constantly making these...towards certain people. He's 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, [[PrepareToDie are a different story...]]
* JerkassFacade: There are times, usually when he is really worn down, that Derek's badass mask slips and he comes across as just a very weary good guy who is scared to show that he cares. 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.
* JerkWithAHeartOfGold: 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 [[spoiler: rather unsuccessfully]] provide cover for Stiles to escape the Kanima, as well as rescuing Scott from being killed by [[spoiler: Victoria Argent]].
* KnightInSourArmour: Derek is extremely cynical about life in general, however, he doesn't give up and keeps trying to do the right thing.
* LeParkour: Derek often leaps and jumps on cars and across buildings rather easily, like most werewolves.
* LivingLieDetector: Like all other werewolves, he can tell when someone is lying by their heartbeat.
* MadeOfIron: 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.
* MrFanservice: 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.
* MoralityPet: He has a ''lot'' of them. Originally it was Scott and (sometimes) Stiles; now the list has grown to include Ms. Blake, Cora, Isaac, and Boyd. Hell, the only main heroic characters that ''don't'' fit this trope are Lydia and Allison (due to their actions in Season 2), and even they are beginning to get to him.
* NeuralImplanting: When his powers go haywire under the influence of monkshood poisoning, he accidentally implanted his memories of the Hale fire and some werewolf relevant trivia into Jackson.
* NoOntologicalInertia: 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 Beta's the Alpha may have turned, so it would at most be situational, or, it could just be a MotivationalLie Derek told in order to get Scott to cooperate with his plans.
* NoSenseOfPersonalSpace: 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.
* NoSocialSkills: Derek's behavior isn't that strange by werewolf standards, but he often comes across as an anti-social creeper to humans.
* NotQuiteDead: 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.
* OffscreenTeleportation: Derek seems to appear out of nowhere in the weirdest places, including the boys' locker room.
* PermaStubble: 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.
* PerpetualFrowner: The number of times he actually smiles on the entire show can be counted on one hand.
* PoorCommunicationKills: Most of the plot of the first five episodes in season one 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.
* PowerIncontinence: Briefly, when shot with a wolfsbane bullet.
* RedEyesTakeWarning: 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.)
** DeathGlare: Derek will often stare down his opponents whenever he is preparing to attack or fight.
* ShirtlessScene: Derek gets one in almost every single episode.
* StalkerWithoutACrush: With Scott primarily. Also, he has a tendency to come off as this to people, including other werewolves and those he wants to join his pack. Stiles has even called him out on it.
* StealthHiBye: This is his primary method of entering scenes. It tends to freak the other characters out a bit.
* StepfordSnarker: Derek sometimes uses sarcasm and cutting remarks to hide his inner and emotional vulnerability or pain.
* SourOutsideSadInside: Gruff to an extreme, but carrying a great deal of guilt and self-loathing inside over the death of his family.
* StalkerWithoutACrush: To Scott, especially in season one. He's making sure newly-bitten Scott wasn't being too destructively disobedient.
* SurvivorGuilt: Derek obviously blames himself for his family's death, as Kate Argent seduced him to get to his family. This also applies to [[spoiler: Boyd’s death.]]
* TranquilFury: Werewolves use anger to transform and gain power. Then, they use an "anchor" to stay human and in control. Scott's anchor is [[ThePowerOfLove Allison]]. Isaac's is [[FondMemoriesThatCouldHaveBeen 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.
* TroubledButCute: Derek is the epitome of this trope.
* UnfitForGreatness: Derek doesn't always believe that he is a good Alpha or strong leader. 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.
* UsedToBeASweetKid: He was very much like Scott as a teenager. [[spoiler:His girlfriend's murder at the hands of Ennis ruined that.]]

!!Allison Argent (portrayed by Crystal Reed)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/allison-1_2514.jpg]]

->"''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.
----
* ActionGirl: Allison is a strong, capable fighter and she is often involved in a lot of the major action, considering that she is a hunter.
** ActionSurvivor: Allison was this in season 1 before she embraced the Argent legacy of being a werewolf hunter and becoming an ActionGirl. Before Allison became a hunter, she was forced to defend herself as much as possible with all of the supernatural events and supernatural beings surrounding her without having any superhuman abilities or any skills in combat or hunting.
** ActionGirlfriend: She may be the love interest of TheHero, 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.
* AlliterativeName: Both Allison's first and last name begin with the same letter: A.
* AnchoredShip: Allison has this type of relationship with Scott. She and Scott go through much chaos and ups and downs throughout the series. Although Allison wants to be with Scott, something or someone always prevents the two from being together or taking their relationship to the next level.
* {{Badass}}: Allison is a tough fighter and a werewolf hunter. Not to mention that she comes from [[BadassFamily a family of werewolf hunters]].
** BadassDamsel: Although Allison is capable of taking care of herself, she does need a little saving sometimes as well, namely by her werewolf love interest and suitor, Scott.
** BadassNormal: Allison isn't a werewolf neither does she possess any supernatural powers and abilities, but don't think she can't kick one's ass and take names when she needs to or has to.
* BeastAndBeauty: Allison is the Beauty to Scott's Beast.olf hunter.
* DatingCatwoman: Allison's romance with Scott. It doesn't help their relationship that Allison comes from a family that hunts Scott's kind, which are werewolves.
* {{Deuteragonist}}: Allison fits this trope as she is the next most important character after Scott. Allison is the main love interest of Scott, who is the TheProtagonist and also the main female character of the series.
* TheDragon: To her Grandpa Argent (Gerard), who was the BigBad of season two. She became so corrupted under Gerard's influence that she basically did all of Gerard's evil bidding. Though nominally the one in charge, Allison was effectivelyGerard's second in command thanks to the way he manipulated her.
* FaceHeelTurn: Briefly, due to Kate's manipulations.
** Happens again in the second season, when [[spoiler: her mother, Victoria, is DrivenToSuicide]].
* GirlNextDoor: Allison originally fit this trope before she embraced her family legacy of being a werewolf hunter. She was the pretty, kind, sweet girl whom was easy to befriend.
* GoodGirlGoneBad: Allison fit this trope especially in season two. Allison was originally the sweet, kind caring girl who was easy to talk to. However, Allison became a much darker person in the second season after the tragedy of losing her mother.
* [[TheHero Heroine]]: Because Allison fights for justice and fights on the good side, she could be seen as the heroine opposite Scott, who is the hero.
* [[HeWhoFightsMonsters She Who Fights Monsters]]: In season two, Allison was a werewolf hunter whose main mission and goal was to hunt and kill as many werewolves as possible. Although it was understandable why she had antagonistic feelings towards all werewolves, who do actually pose a threat to society in general, Allison being ruthless and sociopathic just made her look completely unrecognizable and unsympathetic to other characters and to the audience. Allison may have been hunting "monsters" (the werewolves) but she didn't realize that she was being just as out of control as the creatures she was hunting.
* HeelFaceRevolvingDoor: Pulled between her (mostly) innocent friends and her (mostly) ruthless family. She's usually trying to keep someone alive and safe, but she is a ''bit'' quick to skewer people with arrows. [[spoiler: Poor Boyd and Erica.]]
* HiddenDepths: Allison is apparent skilled in gymnastics and archery and is willing to be a ''bad'' girl at some points despite her normally good girl complex. Though, being the daughter of a werewolf hunter, such should be anything but a surprise.
* IceQueen: In season two, when she does a FaceHeelTurn. She becomes incredibly ruthless, cold, and remorseless.
* InTheBlood: Hunting werewolves. Also being an Argent female in an intimate relationship with a werewolf.
* HeroicBSOD: When Kate reveals the existence of werewolves.
** Once more in the second season as mentioned under FaceHeelTurn.
* KnightTemplar: Allison can be pretty ruthless and hardcore, especially when it comes to saving and protecting her friends. She won't hesitate to kick your ass or even kill you if you harm anyone that she cares about.
* LackOfEmpathy: After Allison did a FaceHeelTurn in season two, Allison seemed to be very ruthless and seemed to have lacked guilt and remorse for her actions. She also loses her empathetic side and becomes a significantly much colder person.
* LoveWillLeadYouBack: Allison seems to have realized the error of her ways during season two due to her relationship and love for Scott. Allison apologized to Scott for all of the immoral things that she had done and for being manipulated by the darkness of her grandfather, Gerard's influence.
* MoralityChain:
* Allison fits this trope in regards to Scott. She prevents Scott from going over the edge as she is the anchor to his sanity and his humanity as a werewolf. He in return helps bring her back from her own dark turns.
* This is explicitly the place of women in her family and why they always choose them as leaders. Unfortunately her grandfather's machinations erroded her effectiveness.
* NewTransferStudent: 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.
* NiceGirl: Allison fits this trope, primarily in season one. She is sweet, sensitive, and caring. [[spoiler: Not so much in the end of the second season.]]
* OnlyFriend: To Lydia. Although Allison is beautiful and sweet, the only person Allison seems to hang out with and befriend is Lydia.
* OrdinaryHighSchoolStudent: Before her family legacy as hunters was revealed to her, Allison was the everyday high school girl.
* OverprotectiveDad: ''Your'' dad may be rude to your boyfriend, but hers pointed a gun in his face with every intention of using it. And not all of that aggression was because of the werewolf-hunter dynamic, based on the awkward family dinner in Season 1.
* PoorCommunicationKills: Actually comparing notes with Scott after the events at the rave might have saved her and several other people quite a bit of pain and suffering.
* RealWomenNeverWearDresses: Allison seems to have internalized this, furiously deriding herself for crying at one point and resenting her own powerlessness after the Night School incident.
* SingleWomanSeeksGoodMan: Allison has said to Lydia that she had promised that she wouldn't get involved with a boyfriend because she was looking for a nice, decent guy. Enter Scott [=McCall=].
* StarCrossedLovers: Allison has this type of relationship with Scott.
* TookALevelInJerkass: Allison definitely fit this trope in season two. She went from down to earth sweet girl to a cold and sarcastic individual.
* UnwittingPawn: Thinks that grandpa Gerard is seriously grooming her to be a leader among the hunters and [[spoiler: helping her avenge her mother's death. He is really just using her as a pawn and rubs it in her face by turning the Kanima on her and offering her to Scott as a bargaining chip]].
* WillTheyOrWontThey: Had this type of relationship with Scott, especially in season one. Much of this was because of Scott's secret identity as a werewolf and the fear that he couldn't tell Allison.

!!Lydia Martin (portrayed by Holland Roden)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/lydia-1_8067.jpg]]

->"''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 [[spoiler:banshee]].
----
* ActionSurvivor: Lydia is not much of an ActionGirl, doesn't possess any superhuman abilities and doesn't have any combat skills. Like Stiles, she depends on her [[BadassBookworm intelligence]] in order to survive and deal with all of the supernatural events surrounding her.
* AllGirlsWantBadBoys: Lydia seems to have a thing for guys who edgy, troubled and tough such as Jackson and ignore the good guys who show interest in her (such as Stiles). She also shows interest in one of the Alpha Twins in season three.
* AlphaBitch[=/=]LovableAlphaBitch: 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. Despite this, she's always sincerely friendly to Allison, Scott, and Stiles, although she’s a bit snarkier towards the latter two.
* AnythingThatMoves: 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).
** In "The Tell", Lydia flirts with Stiles as well, though she was drugged at the time.
** Although it appears to be mostly an act as she only goes as far as flirting and kissing. In the episode "Formality" she states she won't be the type of girl who lifts her skirt to get what she wants. Then again, since she did make out with Scott in "Lunatic", maybe she meant she wouldn't lift her skirt now that Jackson has dumped her.
* {{Badass}}: Lydia is capable of defending herself when she has to.
** BadassBookworm: "I know archaic Latin." Bear in mind, she says this like it's ''no big thing.'' And she knows how to make a self-igniting Molotov cocktail.
** BadassAbnormal: While acting and looking like a normal human, she's sensitive to wolfsbane and supernatural activities, and has a ''piercing'' scream because she's a [[spoiler:banshee]] possibly as a side effect of being bitten by Peter.
* BetaCouple: She and Jackson are initially this to Scott and Allison.
* DitzyGenius: When the ObfuscatingStupidity comes off, Lydia is her old bubbly and dismissive self, even when translating archaic Latin.
* TheFashionista: 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.
* FieryRedhead: Lydia is very feisty and spunky.
* HiddenDepths: Only a small handful of people know how much of a genius she really is.
* TheImmune: [[spoiler: Seemly the only one with this little trick, something that was made a huge deal in season 2. According to Derek there was nothing like her to his knowledge]].
* IntoxicationEnsues: She flirted with Stiles while drugged. He was thrilled... until she called him Jackson.
* LockedOutOfTheLoop: Scott, Stiles, Allison, and Jackson don't tell her anything regarding the kanima or the fact that she's suspected of ''being it herself.''
* ObfuscatingStupidity: 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.
* OnlyFriend: Mutually with Allison. Although Lydia is the popular girl, the only person that she is seen to be associated with is Allison and vice versa.
* ParentalIssues: Her parents are divorced; they left the choice of who to live with to her.
* PsychicPowers: She seems to have a sixth sense about supernatural happenings, likely due to her one-in-a-billion immunity to lycanthropy caused by her being a [[spoiler:banshee]].
* SanitySlippage: [[spoiler: After getting bitten by Peter, she begins to have some serious hallucinations. She also runs naked through the woods.]]
* SignificantGreenEyedRedhead: Lydia has green eyes and red hair; what an extraordinary and attractive combination.
* TheSmartGirl: Lydia is the smartest character on the show. She's a shoe in for validictorian with her 5.0 GPA and her deep knowledge of a wide varriety of subjects.
* SmartPeopleKnowLatin: She ''got bored'' with classical Latin.
* SpiritedYoungLady: Lydia seems to possess a zest and a passion for life in general. She is also rather ambitious.
* TeenGenius: She's roughly sixteen and can make molotov cocktails from memory using the supplies in a high school chemistry room.
* TooDumbToLive: Lydia went to the lacrosse field alone at night when there had been a multitude of 'animal attacks' in town, to the point where there even was a police enforced curfew. Yet she goes to look for Jackson in a place where no one was likely to hear her scream for help. Little surprise that she gets attacked by Peter.
* TheVamp: Tries to be this, with marginal success.



!!Isaac Lahey (portrayed by Daniel Sharman)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/isaac-22_315.jpg]]

->"''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.
----
* AbusiveParents: According to Isaac, his father used to lock him in a freezer. 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.
** Isaac is the epitome of this trope, so much that he's bordering on {{Moe}} territory.
* {{Badass}}: Isaac became tougher and stronger after he was turned into a werewolf and gained superhuman abilities. Isaac was primarily a violence-obsessed beast who wass as obsessed with reveling in his newfound power after a lifetime of weakness as Erica (just with less cleavage and seducing men), but he cried while taking the pain from a puppy with cancer, which melted numerous hearts and hinted that he actually had one. After that, he softened up.
* BerserkButton: 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 ([[spoiler: 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).
* BewareTheQuietOnes: 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.
* BreakTheCutie: His father abuses the holy living hell out of him, leading to his getting the bite.
* DarkAndTroubledPast: His family is extremely abusive.
* TheDeterminator: Once he was hit with the Kanima’s 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. Only [[spoiler: Stiles]] has shown this level of willpower in a similar situation
* DrunkWithPower: 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 HeelFaceTurn.
* DysfunctionJunction: 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.
* FakeAmerican: Daniel Sharman, his portrayer, is British.
* FakeGuestStar: At this point, the fandom isn't wondering ''if'' he'll get an official PromotionToOpeningTitles, but ''when.''
* FanNickname: "The Puppy."
* GoodThingYouCanHeal: [[spoiler: Allison, during her phase as Gerald's pawn]], carves him like Halloween pumpkin from InTheBack during the final battle of the 2nd season, but a few seconds later he’s fully healed
* HeelFaceTurn: Towards the end of the season, 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.
* HeroicWillpower: Out of the three new Betas he’s 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)
* [[spoiler: HopeBringer: Coming back to help Scott when he needs it the most after his HeelFaceTurn. After all, he "came to win." The look of hope and relief on Scott’s face is unmistakable when he realized he had another ally during his DarkestHour]].
* MissingMom: The whereabouts of his mother are unknown. It is most likely that Isaac's mother had died when he was younger.
* KickTheDog: Isaac's jackass of a father locked him in a freezer as a kid? ''Why, yes, please lock him in a small utility closet.'' Said father would chuck glasses and plates at him? ''Please, by all means, have Derek do the exact same thing to him when kicking him out.'' Worst yet? ''Derek knew exactly what he'd done.''
* NiceGuy: He was this as human, or strongly hinted. After his HeelFaceTurn and TookALevelInKindness Isaac has seemingly returned to his roots as an {{Adorkable}} NiceGuy
* NumberTwo: For Derek. Boyd and Erica where seen together with Derek just as much, But Derek seems to have taken a particular shine to Isaac and something of a bond. This especially seen when Derek gently (or as gently as Derek can do anything) explains the notion of finding an Anchor to control his transformation to Isaac and later when a fully controlled Isaac helped to subdue a feral Boyd
* PowerOfLove: 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 AbusiveParents his father was, Isaac just smiles fondly and states that he wasn’t always like that, obviously drawing on his happy memories with his father to serve as his Anchor
* PromotionToOpeningTitles: Was supposed to happen in Season 3, but didn't. Regardless, he's essentially [[Series/BuffyTheVampireSlayer pulling a Tara]] at this point in that he’s a main character with guest billing.
* SixthRanger: Isaac seems to becoming more of this to Scott, Stiles, Allison, Derek and Lydia. At the end of season two, unlike Boyd and Erica, who left Derek's pack, Isaac decided to stick around and help Scott (and all of Scott's friends) in the fight against Gerard and the Kanima. His relationship with the core group will likely become closer due to his growing friendship with Scott.
* TenderTears: When he uses his HealingHands ability to drain some of the pain of a puppy
* TookALevelInBadass: 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.
* TookALevelInJerkass: Initially. Eventually, he [[TookALevelInKindness takes several levels the opposite way.]]
* TookALevelInKindness: Mostly due to Scott's influence, Isaac became a much kinder, gentler and understanding person who wanted to do the right thing as much as possible.
* WolfMan: When Isaac shifts into a wolf, he is still humanoid in appearance albeit with wolf-life features.

!!Peter Hale (portrayed by Ian Bohen)
[[quoteright:236:http://static.tvtropes.org/pmwiki/pub/images/tumblr_m6hzmdTrfW1rzbosjo2_250_2508.png]]

->"''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 BigBad 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.
----
* AffablyEvil: 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.
* [[spoiler: AndIMustScream: 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".]]
* AntiVillain: While his targets initially seem random, it soon becomes apparent that he's hunting down the people responsible for murdering his family and leaving him crippled.
* [[spoiler: BackFromTheDead: Manipulates Lydia from beyond the grave into orchestrating a ritual that returns life to his dead body.]]
* {{Badass}}: Quite possibly the most Badass character in the series. As the BigBad of the first season he was a LightningBruiser MagnificentBastard who not only was several steps ahead of the competition, but going head to head with him was almost suicide. Come season 2 and he’s [[spoiler: BackFromTheDead and not only holding the SmartBall firmly in his hands, but also showing up everyone left and right and playing an crucial part against The Kanima]]
* BigBad: 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. He also killed Allison's aunt, Kate, in cold blood as revenge for Kate and her family burning up his house and killing members of his family.
** BigBadEnsemble: Peter, along with Kate, were the primary villains of the first season. Peter was murdering people within Beacon Hill and Kate was out to kill absolutely every single werewolf that existed. Kate also subjected to torturing Derek at the the end of the season. However, Peter and Kate weren't much of an ensemble considering that Peter was the one to brutally kill Kate after ripping out her throat.
* BigBrotherInstinct: As a young adult, he was ''very'' protective of Derek.
* CurbstompBattle: To Derek in the hospital when it's revealed that he's the Alpha.
* DeadpanSnarker: Despite some of his snark being really creepy, Peter can give Mr. Stiles Snark-linski a run for his money in the witty snark department.
--> "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."
* [[spoiler: EnemyMine: 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.]]
* EvilCannotComprehendGood: ''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.
* EvilUncle: He killed his niece, Laura, in order to become the Alpha.
** CoolUncle: There are some very subtle hints that he used to be this before the death of his family and him becoming the EvilUncle seen proper in the series
* ExpositionBeam: 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.
** [[spoiler:BrainUploading: Implanted an imprint of himself in Lydia, just in case he died and needed someone to resurrect him.]]
* HandsomeLech: 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.
* HealingFactor: Peter had died when he was the Alpha, but he possesses a very powerful regeneration or healing factor. Despite the fact that he came back from the dead and healed, he admits that he is a lot weaker after he had come back from the dead.
* KillItWithFire: It seems that this particular method has been thoroughly exhausted on Peter, so something new might be needed if he goes evil again.
* ManipulativeBastard: 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.
* MoreThanMindControl: Using his Alpha status to force Scott into wanting to murder.
* NotSoDifferent: Between Derek and himself. When Derek calls him a psycho, Peter points out that Derek jumps to [[MurderIsTheBestSolution killing all his problems]], like the Kanima and specifically [[spoiler:Peter himself: "You're the one that ripped ''my'' throat open".]]
* ObviouslyEvil: Lampshaded by Stiles, who points out his cliché villainous traits (red eyes, fangs, turning into a wolf in general) to wryly refute his claim that he's "not the bad guy".
* RedEyesTakeWarning: An innate trait of every Alpha, made more sinister by his actions. [[spoiler: He almost certainly no longer has red werewolf eyes since his return from the grave.]]
* RoaringRampageOfRevenge: He's more than little unhinged by the slaughter of his family.
* ThrowingOffTheDisability: After the fire, he was left burned and comatose for six years while his cells ''slowly'' healed him.
* [[spoiler:TokenEvilTeamMate: 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.]]

!!Kate Argent (portrayed by Jill Wagner)
[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/200686969_1253.jpg]]

->"''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.
----
* ActionGirl: She's just as willing as the male hunters to take up weapons and fight to kill the werewolves in Beacon Hills.
** DarkActionGirl: And the killing of innocents throws her into the darker reaches of the action girl trope, too.
* AntiVillain: Just like most of her family, she isn't necessarily evil for the sake of being evil. Kate truly believes that every single werewolf must be destroyed in order to protect humans.
* AxCrazy: And she'd gladly chop a werewolf in half with one, too.
* BigBadEnsemble: With Peter Hale.
** DragonAscendant: It's implied she was once Gerard's [[TheDragon dragon]].
* BelligerentSexualTension: With Derek. Apparently he was once in love with her, but she might have been playing him.
* BloodKnight: On some level, Kate ''might'' indeed think that killing werewolves is best for humanity, but, looking at her actions, you get the feeling that she enjoys it a bit too much to be anything but lucky for the handy 'but it doesn't count, they're not human' excuse to kill people.
* CoolBigSis: Allison describes her as more like ''her'' sister than her father's. Whether this attitude was sincere familial affection or the desire to follow in daddy's footsteps by crafting her own psychopathic werewolf-killing machine is debatable.
* CoolAunt: Kate's the fun aunt, the one you can talk to about your problems...
* CuteAndPsycho: ... she's also the kind of aunt who thinks a good aunt-niece bonding exercise is torturing somebody.
* DaddysLittleVillain: Kate's much more ruthless than her brother and doesn't follow the Hunter's Code, something that Gerard took great pride in.
* FantasticRacism: She '''hates''' all werewolves. But as if to illustrate how depraved she is, she is apparently quite willing to have sex with them for all that she considers them to be inhuman.
--> '''Kate''': “Oh, this one grew up in all the right places. I don’t know whether to kill it or lick it.”
* FemmeFatale: She used her charms to endear herself to a younger and more naive Derek, which later led to her slaughtering the Hale family.
* InterplayOfSexAndViolence: Despite their relationship having been a) (probably) a means to the ends of murdering his entire family and b) over for six years, Kate always uses highly sexualized language when talking to Derek, even (or especially) when causing him harm.
* KilledOffForReal: Peter gashes her throat open with his claws because she killed his family.
* MeaningfulName: Katherine can mean "to torture." Guess what Kate likes to do to werewolves?
* PetTheDog: Despite Kate's awful attitude towards werewolves, she is a loving aunt to Allison.
* PsychoExGirlfriend: Subverted: Kate's desire to kill Derek (and his entire family) wasn't a WomanScorned response to breaking up, it was the entire basis for her starting the relationship in the first place.
* PsychoSupporter: Of her father, from whom Kate learned all of her... genocidal craziness.
* PsychoticSmirk: When she's killing werewolves, oh yes.
* [[HeWhoFightsMonsters She Who Fights Monsters]]: Kate's ''a lot'' more ruthless and violent in her methods than almost all of the werewolves she's hunting. She's also willing to use innocent ''humans'' as collateral damage if it's necessary.
* TheSociopath: She'll happily kill any werewolf who crosses her path, even if they've never hurt another person in their whole life. And humans who get in the way are just collateral damage.
* TermsOfEndangerment: Calls everyone sweetie. Even when she's torturing them.
* WouldHurtAChild: If they're a werewolf or associated with werewolves, as demonstrated by her burning of the Hale house, which killed several humans and young children.

!!Gerard Argent (portrayed by Michael Hogan)
[[quoteright:320:http://static.tvtropes.org/pmwiki/pub/images/Gerard-Argent_3366.jpg]]

->"''No Code. Not anymore.''"

Allison's grandfather and Kate's father, who also 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.
----
* AbusiveParents: [[spoiler: He molded his daughter into a genocidal lunatic and was willing to kill his own son and granddaughter to cure his cancer by becoming a werewolf.]]
* [[ArchnemesisDad Archnemesis Grandpa]]: Allison does her best to undermine his plans to murder Scott until [[spoiler: he's able to manipulate her using the Grandpa part to make her think they'd be better on the same side.]]
* AxCrazy: He can be just as crazy as Kate in his pursuit of ridding the world of werewolves. And if he could take an axe to them all, he glady would.
* BadassGrandpa: Despite being a geriatric psychopath, Gerard scares the crap out of everybody around him.
* BigBad: Of season two.
* TheChessmaster: He spends nearly all of season two playing everybody around him like a fiddle, including his own granddaughter.
* TheDreaded: Feared by pretty much everyone, including his own family.
* EvilOldFolks: Gerard's so bent on killing werewolves that he's willing to beat the snot out of Stiles, a ''human'' teenager, in order to send a message of intimidation to Derek and Scott.
* FantasticRacism: He's the one who taught it to his daughter, so no questions there.
* FauxAffablyEvil: He lampshades this himself when monologuing to Scott (with a knife ''in'' Scott's stomach) about how good he is at playing doddering old grandfather.
* HeWhoFightsMonsters: Any credibility his 'werewolves are monsters' rhetoric might have falls flat in the face of his being a more sadistic predator than Peter at his worst.
* {{Hypocrite}}: Hates werewolves and plans to kill them all, [[spoiler: but his master plan involves becoming one to cure his cancer. This is revealed after he forced his son to kill his wife when she is bitten.]]
* IHaveYourWife: Gerard has a terrible habit of holding the lives of loved ones over Scott's head. Most prominently, Scott's mom. [[spoiler: Also, Stiles, Allison, and ''everyone'' present at the final lacrosse game.]]
* ItsAllAboutMe
--> '''Gerard''': [[spoiler:When it comes to survival, ''I'd kill my own son!'']]
* [[spoiler: KarmicDeath: Implied. He has himself bitten by Derek, but since Scott messed up his pills with mountain ash, he starts bleeding black blood from his eyes, ears and mouth.]]
* JerkwithAHeartOfJerk: You don't even know the half of it.
* ManipulativeBastard: Uses Scott's mother to control Scott, [[spoiler: all but forces Victoria to commit suicide, then uses her death to shape Allison into Kate 2.0]].
* OffingTheOffspring: He's willing to murder his son and granddaughter in order to guarantee his own survival.
* ThePatriarch: Despite Season 2 being the season where it's first brought up that the Argent men are soldiers and the ''women'' are leaders, Gerard takes complete control of hunter operations in Beacon Hills from the word 'go' for basically no reason other than being Chris's dad.
* RoaringRampageOfRevenge: He ''claims'' that he has decided that werewolves can no longer be allowed to continue existing because of the death of his daughter at the hands of one; as if he needed the excuse to set off a genocidal crusade.
* TheSociopath: He's just as crazily bent as his daughter about committing genocide against all werewolves in Beacon Hills. And probably the rest of the world, if he was given half a chance.
* ThisMeansWar: Kate's death is the catalyst for his RoaringRampageOfRevenge against werewolves.
* VanHelsingHateCrimes: Even his own son, a fellow werewolf hunter, refers to Gerard's intentions as genocide.
* VillainousBreakdown: Has one when he finds out Scott pulled a BatmanGambit on him. His exact words ?
--> '''Gerard''': [[LargeHam KILL THEM ALL!!!.]]
* WickedCultured: Has a tendency to quote Shakespeare at the slightest provocation.
* WouldHurtAChild: In Gerard's eyes, ''anyone'' associated with or connected to werewolves needs to die. And this includes human teenagers like Stiles, who's nothing more than a means to an end in old man Argent's opinion. He is not impersonal about it either, using the Kanima to [[spoiler: threaten the life of his own granddaughter. Also, despite his supposed anger over his daughter's death, he states flat out that he would sacrifice his son's life if it helped his own survival. Mind you he says this ''in front of'' the son in question]].

->"''So long as you stay strong, we won't have to kill a sixteen-year-old boy.''"

The [[EvilMatriarch matriarch of the Argent family]], who is possibly the most ruthless of them all.
----
* TheBaroness: While she may not be a hunter herself, as the matriarch of the family, she is their official [[TheLeader leader]].
* DisproportionateRetribution: 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.
* [[spoiler: DrivenToSuicide: After being bitten by Derek, she impales herself with a knife right as she begins transforming into a wolf on a full moon.]]
* TheDragon: Even though she was the overall leader of the hunters, she answers to Gerard.
* EvilMatriarch: Tries to murder Scott and make it look like an accident for having sex with her daughter.
* FreudianThreat: Asks Scott if he's sleeping with her daughter while sharping a fresh pencil to a stump.
* FurAndLoathing: 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.
* KarmicTransformation:[[spoiler: Quite a lot of people cheered when the bitch got chomped by an alpha and turned into what she hated.]]
* LaserGuidedKarma: [[spoiler: Right after she attempts (and fails) to kill Scott, [[KarmicTransformation she is bitten by Derek, thus beginning her own transformation into a werewolf]] ]].
* MamaBear: Have sex with her daughter? [[spoiler: Hope you like a slow death by wolfsbane vapour.]]
* PowerHair: Victoria has hair shorn even shorter than Hilary Clinton's, very controlled (just like her).
* PrinciplesZealot: Actually [[spoiler: commits suicide rather than become a werewolf, even though she knows it can be controlled and the action will probably have negative emotional consequences for her daughter]].
* SilkHidingSteel: ''Barely'' hiding, but she switches from offering cookies to ordering murders to complaining about academic standards dropping to torturing people on a dime.

->"''That's what Jackson's for. I just think about killing them, and he does it.''"

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.
----
* BreakTheCutie: TheJoker puts it best: “All it takes is one bad day to reduce the sanest man alive to lunacy”. Matt just suffered a horrible day once upon a time, and the rest is history
* DiscOneFinalBoss: Unceremoniously offed by Gerard, which lets him assert himself as primary Season 2 BigBad ''and'' [[FromBadToWorse take Matt's place as master of the Kanima]].
* DoggedNiceGuy: For Allison, who only has eyes for Scott. It later turns out that he's not as nice as he seemed.
* EvilAllAlong: 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.
* FromNobodyToNightmare
-->'''Derek''': This is the one controlling the kanima? This kid?
* HeWhoFightsMonsters: Yeah, being drowned by a bunch of drunken teenagers is awful. Also awful? Murdering all of those teenagers in cold blood 5 years later.
* IfICantHaveYou: He says this almost word for word. He originally [[DefiedTrope defies it]], but he ultimately plays it straight.
* KilledOffForReal: Drowned in a river by Gerard Argent, flashing back to his drowning in the pool that started the whole mess.
* TheManBehindTheMan: The Kanima seeks a master. He's it.
* MonsterSobStory: He drowned in a pool when he was younger, which kicked off a...
* RoaringRampageOfRevenge: He even compares himself to Orestes, seeking vengeance against those who wronged him by standing by while he drowned.
* StalkerWithACrush: His camera is full of candids of Allison that she didn't know about. Lampshaded by Allison herself, who shoots down his [[StalkingIsLove 'I couldn't help myself, you're just so beautiful' Edward Cullen act]] and judo-flips him.
* TheStoic: 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.
* TheUnfettered: He really has one single solitary goal: Allison Argent. [[spoiler: That, and getting revenge on the swim team for drowning him.]]
* WalkingSpoiler: Even him being in the Villains folder barely scratches the surface of how much he's hiding.

The new english teacher appearing in season 3, she is soon embroiled in the Beacon Hillls supernatural community after nearly being killed by [[spoiler: Cora and Boyd]], and saved by Derek.
----
* BigBad: One of Season 3's main antagonists, and arguably a bigger one than the Alphas given that they're opposed to her as well.
* BitchInSheepsClothing: And frigging how. She acts like a delightful and friendly individual, only to turn around and casually [[spoiler:attempt to kill Lydia]].
* CoolTeacher: Texts her students the closing line of ''Literature/HeartOfDarkness'', both to get them interested in the book and to inform that it is the last text they will receive in her class.
* DarkAndTroubledPast: Mentions being in psychotherapy, and has been emotionally okay "for a long time".
* DeadpanSnarker: Upon having to treat Derek’s injuries, she jokes that it’s the weirdest first date she’s ever had.
* DistressedDamsel: She’s been in bad situations twice since Season 3 began, requiring aid from Derek and Isaac, respectively.
* GameFace: Has one in the form of the [[spoiler:Darach]].
* GenreSavvy: Fully expects Derek to kill her, or at least tell her that nobody will believe her if she tells them what she saw. [[WrongGenreSavvy He doesn't]], and actually does his best to make her feel okay.

The mysterious blind leader of the alpha pack.
----
* EvilIsHammy: To the point where he [[spoiler: cracks the lenses of his sunglasses with his eyes]] while delivering a monologue. He even outdoes Gerard's infamous "MOUNTAIN AAAAAAAAAAASSSSSSSHHHHH!!!" from the season 2 finale.
* EyeScream: [[spoiler: Had his eyes gouged out by Gerard, who jammed two flashbang arrows into them. Jesus.]]
* HandicappedBadass: He’s functionally blind, and he still is able to beat down Scott and Derek.
* ManipulativeBastard: He killed Ennis to gain more power after the latter was expected to survive his fight with Derek, and didn’t tell Kali, Aiden, or Ethan about this. Naturally, the trio is now out for Derek’s blood.
* OffingTheOffspring: In a sense, given that he began advocating the murder of betas after [[spoiler:killing one of his own when said beta tried to [[TheStarscream take the newly blind Deucalion out thinking he’d have an advantage]], thus increasing his power.]]
* SinisterShades: Justified: he's blind [[spoiler: to a point.]]

Graceful and deadly, Kali stands as Deucalion's right hand within the Alpha Pack.
----
* DarkActionGirl: Action enough to take down Derek and impale him with one of his own pipes, Dark enough to ''really'' enjoy it.
* DoesNotLikeShoes: Has never been seen wearing footwear that would restrict her gnarly knife toes, even when disguised as a nurse (which should have raised red flags for ''someone'').
* TheDragon: Kali has thus far been the only Alpha 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.
* FauxAffablyEvil: 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.
* FemmeFatalons: Inverted. While Kali does have the standard issue werewolf fingernails, she makes combative use primarily of the nails on her feet.
* KickChick: Kali prioritizes attacks with her feet to make use of her razor sharp toenails.
* TermsOfEndangerment: Refers to [[spoiler: Cora]] as "little sister" in a deeply unsettling manner.
* TwoferTokenMinority: Based on the name and casting call (though not based on the actress), Kali is Indian in addition to being [[TheSmurfettePrinciple the only female Alpha]].

!!Ennis (portrayed by Brian Patrick Wade)
[[quoteright:223:http://static.tvtropes.org/pmwiki/pub/images/ennis_4095.png]]

-->"''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.
----
* TheBrute: Purely muscle, primarily tasked with hitting things and not possessing Kali's level of clout with Deucalion.
* ItsPersonal: [[spoiler: He turned Derek’s first love, Paige... Or he tried to; anyways; she didn’t take the bite and died, prompting Derek’s change from an goofy teenager into a brooding adult. Derek takes a particular dislike against him as a result.]]
* {{Jerkass}}: He’s been nothing but a pompous ass ever since his introduction.
* KilledOffForReal: Deucalion takes him out to gain more power for himself.
* SmugSuper: Lords his status over Scott before getting out-Alpha'd by Derek.

!!Aiden and Ethan (portrayed by Max and Charlie Carver)
[[quoteright:325:http://static.tvtropes.org/pmwiki/pub/images/alphas_8064.png]]
[[caption-width-right:325: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.
----
* EvilGenius: According to the casting call, Ethan "has a brilliant mind that he uses for devious calculation".
* FusionDance: Aiden and Ethan can do this, melding together (somehow) to form a burly gigantic monster.
* [[GoSeduceMyArchnemesis Go Seduce Two Of My Archnemesis' Human Friends]]: Their mission is to seduce Lydia and Danny in order to sabotage Scott. Given that [[spoiler: Lydia now knows that they're alphas]], things ''may'' not go exactly according to plan.
* MagicPants: Aiden and Ethan when they do their FusionDance to merge into the "Super-Alpha". The trope is played especially straight in that for some reason they [[{{Fanservice}} remove their jackets and bare their torsos]] before merging, but their pants (and shoes) merge when their bodies do.
* MoralityPet: Danny is one for Ethan: When Danny’s around, Ethan is less antagonistic to Scott and his group, and is even helpful at times.
* NewTransferStudent: Like most supernatural creatures who just up and enroll in a public school, it is unclear as to who exactly Aiden and Ethan's purported parent/guardian is. Deucalion is only barely of an age where he could pass as their father. The twins just show up on the first day of the school year and make their presence known.
* StraightGay: Ethan is apparently not straight, as evidenced by his interest in Danny and the observation that Lydia makes that she states that wants one one of the twins. When Allison asks her which one, her response is "The straight one (Aiden) obviously".
* RedOniBlueOni: Aiden (Red) is much more fiery, aggressive, and prone to violence, while Ethan (Blue) is more passive and friendly
** SiblingYinYang: They work in tandem, but Ethan and Aiden are different in personality.
* TeensAreMonsters: At least part of their Beacon Hills High goal is antagonizing Isaac into hurting someone though means like [[PokeThePoodle giving him detention]] and [[KickTheDog exploiting his claustrophobia by trapping him in a closet with Allison]]. Not to mention that, as members of the Alpha Pack, they've implicitly murdered their previous pack or packs.
* WoundedGazelleGambit: The Twins draw Isaac out into the hallway, do a showdown at high noon style stand-off, and start throwing punches... at each other. Then, when the teacher and other students are ''just'' about to appear, one twin throws the other at Isaac's feet and vanishes, making him like the aggressor who doesn't have a scratch on him.

!!Vernon Milton Boyd IV (portrayed by Sinqua Walls)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/boyd-22_8093.jpg]]

->"''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.
----
* TheDeterminator: HumanPincushion or not, Boyd didn’t for one second try to stop trying to take down Allison in order to protect Erica. Even Chris Argent was completely surprised at Boyd’s willpower, judging from his face when looking at Boyd
* [[spoiler: EmbarrassingFirstName[=/=]TwoFirstNames: If the combinations of tweets by Jeff Davis and MTV's legal department is to be believed, his full name is Vernon Boyd IV. TwoFirstNames applies to the point where many fans thought Boyd ''was'' his first name and that the writers were holding out on his last name.]]
* GentleGiant: 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.
* HiddenDepths: 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.
* IJustWantToHaveFriends: The reason he agrees to join Derek's pack
* KilledOffForReal: By Derek as a result of the Alphas..
* OrdinaryHighSchoolStudent: Boyd was this before he was turned into a werewolf and gained superhuman abilities.
* TakingTheBullet: An incredibly big part of the reason Boyd was made into a HumanPincushion was the fact that he was essentially shielding Erica from DarkActionGirl Allison. With his body
* [[TokenMinority Token Black Werewolf]]: Boyd is the only Black werewolf in the series, or at least so far.

!!Erica Reyes (portrayed by Gage Golightly)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/erica-22_8575.jpg]]

->"''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 [[TheVamp vamp]] with eyes for, well, pretty much everyone, having made advances on Derek, Scott, Stiles, and Allison.
----
* ActionGirl: Erica was not an action girl before she became a werewolf. After she turned, she became significantly stronger and a much more capable fighter.
* ActionFashionista: Erica is an ActionGirl but also seems to have a penchant for fashion and trendy clothing.
* AlphaBitch: Becomes this upon getting the bite.
* AmbiguouslyBi: She was completely willing to try to seduce Allison.
* BlessedWithSuck: Lycanthropy [[CurseThatCures 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.
** Also, 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.
** Then, 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''.
* ConvulsiveSeizures: Erica was an epileptic before Derek turned her.
* EvenTheGirlsWantHer: 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.
* FromNobodyToNightmare: When Erica's first introduced, she's a troubled, skittish epileptic ostracized by the entire school. Then Derek gives her the bite. WhosLaughingNow
* IWillOnlySlowYouDown: 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.
* MyBreastsAreDownHere: She clubs Stiles over the head for looking strictly at her eyes and refusing to go any lower or acknowledging her body in anyway. This, after she went from unflattering sweats to the closest thing the show has to a CleavageWindow, post transformation.
* ShrinkingViolet: Before her transformation, she clearly had no friends and was shaking like a leaf at how deep in her personal space Derek was while offering the bite.
* TookALevelInJerkass: 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.
* TheVamp: 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.

!!Cora Hale (portrayed by Adelaide Kane)
[[quoteright:280:http://static.tvtropes.org/pmwiki/pub/images/cora-22_116.jpg]]

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.
----
* ActionGirl: 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.
* DeadpanSnarker: 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.
* MoralityPet: One of Derek’s.
* MysteriousPast: There hasn't yet been any explanation of what she was doing in the years since the Hale fire or how she didn't know that Derek, Laura, and Peter were still alive.
* SnarkToSnarkCombat: She has to tendency to do this with Stiles, much like her brother.

!!Adrian Harris (portrayed by Adam Fristoe)
[[quoteright:232:http://static.tvtropes.org/pmwiki/pub/images/13591554654_1530.jpg]]

->"''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.
----
* TheAlcoholic: 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.
* [[spoiler: AssholeVictim: He gets murdered at the end of 3.04.]]
* {{Expy}}: Seems very much like a Severus Snape expy.
* {{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 also was working with the Darach, only to be betrayed and murdered.
* SadistTeacher: Consistently singles out and verbally abuses Stiles in class to levels that would (and should) get him ''fired''.
* TheScapegoat: Whenever something bad happens, he is usually the first person to be suspected by both the audience and the characters, and in return Stiles seems to be his scapegoat for anything that goes wrong in class.

!!Bobby Finstock (portrayed by Orny Adams)
[[quoteright:298:http://static.tvtropes.org/pmwiki/pub/images/profilcrop754475457_3508.jpg]]

->"''The bigger they are...the bigger they are!''"

The mentally unstable lacrosse coach and economics teacher at Beacon Hills High School.
----
* AttentionDeficitOohShiny: 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.
* BunnyEarsLawyer: 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.
* ImaginaryFriend: WordOfGod 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.
* JerkWithAHeartOfGold: 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 it’s not like I hate you guys. Well, I kind of hate Greenberg, but... That’s different. It’s Greenberg."
* '''LargeHam''': It's best highlighted in the speeches he gives before games in the locker room.
* SadistTeacher: And coach, though for comedic effect.
-->'''Finstock''': *laughing* I don't know why, [=McCall=], but your pain gives me a special kind of joy.
* UnfortunateName: Inverted. He wants to be called "Cupcake".

!! Marin Morrell (portrayed by Bianca Lawson)
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/141538446564545_2344.jpg]]

->"''If you're going through hell, then just keep going.''"

The kind-hearted French teacher and guidance counselor at Beacon Hills High School. She works alongside her older brother, Dr. Deaton, in tracking down supernatural problems around Beacon Hills.
----
* ActionGirl: She can fight Allison on equal footing.
* AllTherapistsAreMuggles: Inverted in Lydia's case as she receives counselling from her having no idea her problems are supernatural in origin, and subverted when Stiles goes to her and does the usual "gloss over the werewolf side of things" because he doesn't know that she's pretty much on par with Deaton on the "knowing more about this werewolf business than the actual werewolves" scale.
* {{Badass}}: She can go toe-to-toe with hunters.
** BadassBookworm: She has over 300 hours of field work and a masters degree in behavioral psychology.
** BadassTeacher: If she's working with Dr. Deaton, then this trope is practically guaranteed.
* FaceHeelTurn: She's seemingly joined the Alpha Pack as their human liaison (much like her elder brother was for the Hales years prior), although it also is implied that her motives are firmly on the side of good.
* HotTeacher: Lydia seemed to think that she was nothing more than this until Ms. Morrell listed all of her credentials.
** PsychologistTeacher: And she's got an actual degree in psychology, too!
* ReasonableAuthorityFigure: Although she will give detention to her students if she catches them snooping into supernatural affairs.

->"''Our sons are trained to be soldiers... our daughters to be leaders.''"

The chief enforcer of the Argent family, who answers only to his wife, the leader of the clan.
----
* AntiVillain: Borderline TokenGoodTeammate, here. Even in her grief his daughter proved to be considerably more brutal to his liking
* ArmsDealer: He sells firearms and munitions to law enforcement agencies to conveniently explain why he has so many of them.
* BadassNormal: He’s the chief enforcer of the Argent Family and when it comes time to kick ass, he really kicks ass
* BeingEvilSucks: Granted, he does not see himself as evil. But the whole [[TheHunter hunter]] thing [[spoiler: virtually destroys his family]].
* CodeOfHonour: Pretty much the only Argent who actually follows it.
* EvenEvilHasStandards: Toward his father's KillEmAll attitude regarding wolves. It eventually reaches it's peak when he and Scott team up to stop Gerard.
* GoodParents: He only wants the best for his daughter and is ''not'' happy when Gerard recruits her into the most violent parts of the family business.
* TheHunter: One member of a long line of people who have sworn to protect humans from werewolves, going back to the Beast of Gevaudan.
* KnightTemplar: Chris genuinely sees his profession as essential to the protection of human beings. But, more often than not, it just seems to cause suffering and death for humans and werewolves alike.
* MyGodWhatHaveIDone: [[spoiler: Starts feeling this after he helps his wife kill herself and his daughter begins to show signs of becoming a psychopath like his father and sister]].
* NeverHurtAnInnocent: Essentially what his CodeOfHonor is, and yes, for him this also includes Werewolf. As long as the Werewolf hasn’t hurt anyone he will not hunt them down
* OverprotectiveDad: 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.
* PapaWolf: Seriously, stay away from his daughter. Especially romantically; he ''will'' shoot you.
* RetiredBadass: He gives up on the hunting business between seasons 2 and 3, due to the strain on his family.
* TeethClenchedTeamwork: The only reason he hasn't killed Scott is because he's gotten his help before. Well, that and because Allison would be devastated.
* UnwittingPawn: [[spoiler: 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 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]].

->"''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 no clue the wiser about what's going on in Beacon Hills.
----
* AllLoveIsUnrequited: His crush on Matt, whom he knows won't reciprocate, since Matt has [[{{Understatement}} a crush]] on Allison -- who doesn't reciprocate him either.
* [[WomanScorned Boy Scorned]]: {{Downplayed}} and PlayedForLaughs; after being [[AndIMustScream attacked by the kanima]], Danny is asked if he's okay. After receiving confirmation that the paralysis happened to his ex as well, he darkly says that he's great.
* ClosetGeek: He's so far helped both Stiles and Jackson with rather complicated tech work.
* DatingCatwoman: He and [[AntiVillain Ethan]] are dating
* DeadpanSnarker: Has shown signs of this, especially when talking to Jackson.
* GayBestFriend: Played straight with Jackson. Jackson is straight and has no problem with the fact that Danny is gay.
* IncompatibleOrientation: He has a crush on Matt, who is straight and seemingly only has eyes for Allison.
* LovableJock: He's one of the nicest guys on the lacrosse team and even Jackson is never mean to him.
* MoralityPet: He's Jackson's best friend and the only person Jackson is consistently not a total jerk to.
* NiceGuy: Almost all of the characters like him and he's consistently nice to everyone around him. Except when Stiles is pestering him.
* PlayfulHacker: 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.
* StraightGay: When he's not, you know, ''playing lacrosse'', his interests extend more towards hacking and other programming than, say, musical theatre.
* TeenGenius: Of the tech variety.
* TokenMinority: 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 and most scenes he's featured in manage to draw attention to his sexuality.

Scott's snarky but well-meaning single mother, who, [[spoiler: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.
----
* DeadpanSnarker: She’s 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:
→”...my heroes.”
* GoodParents: Not just to Scott, but to Stiles and Isaac too.
* HandsOffParenting
-->'''Ms. [=McCall=]:''' Don't either of you care that there's a ''police-enforced curfew''?
-->'''Scott and Stiles:''' ...no.

* HelloNurse[=/=]HospitalHottie: She's an R.N. at Beacon Hills Memorial Hospital.
* MamaBear: She does ''not'' react kindly to Mr. Argent's implication that her son is dragging down his daughter.
** It’s also a very poor idea to screw with Stiles or Isaac around her.
* ParentalSubstitute: To Stiles and Isaac.
* TeamMom: She's increasing into this role as of Season 3, helping Stiles in his research and also giving Isaac a place to stay.
* VillainOverForDinner: She gets asked out on a date by Peter, the Alpha, much to Scott's horror.
* WeirdnessCensor: 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.

->"''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:''' [[OhCrap Oh no]]. Why is my son running out to the field?
-->'''Ms. [=McCall=]:''' Because he's on the team?

-->'''Stiles:''' [[AmazinglyEmbarrassingParents Oh, dear God]].
* {{Badass}}: He’s a hell of a shot with a pistol.
* BigDamnHeroes: He saves Dr. Deaton from hanging when Scott is unable to due to a Mountain Ash barrier.
* DaChief: Highest ranked officer of the law in Beacon Hills.
* DeadpanSnarker: He can hold his own against his son most of the time.
* GoodParents: He's a very good father and does the best that he can for his son.
* LockedOutOfTheLoop: Scott wants to tell him about the supernatural chaos around Beacon Hills, but this is vetoed by Stiles, who doesn’t want to risk becoming an orphan by getting his dad involved.
* OnlySaneMan: It's pretty obvious that he feels like this around Scott and Stiles a lot of the time.
* PapaWolf: 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.
** It’s likely that harming Scott would set off a BerserkButton, too.
* ParentalSubstitute: To Scott.
* ReasonableAuthorityFigure: He ''is'' the sheriff.
* [[TenMinuteRetirement Ten Minute Forced Retirement]]: Fired when his son's unexplained night-time activities pile up a bit too high. Re-hired after [[spoiler: Matt's murder.]]

->"''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.
----
* TheAlcoholic: His drunkenness at the dance ends up causing a ''lot'' of trouble for Scott.
* AlphaBitch: A male version: he flashes his wealth at every opportunity, puts down the protagonists whenever he can, well-connected family, he's basically Draco Malfoy.
* AlwaysSomeoneBetter: Jackson felt this way about Scott in season 1. He felt that Scott stole the spotlight from him and therefore, Jackson began to resent Scott and became Scott's main [[TheRival rival]].
* BadassNormal: He and Stiles rush into the fray against Peter, the [[BigBad Alpha]] of Season 1.
* BastardBoyfriend: Jackson wasn't always the best boyfriend to Lydia and didn't always treat Lydia respectfully. In fact, there were times when Jackson was just downright abusive and jerkish towards Lydia.
* BigBad: Jackson was this in season two, [[spoiler: as the Kanima.]]
* BigManOnCampus[=/=]SchoolIdol: Jackson likes to think of himself as this, but in reality, he is just a JerkJock who is arrogant and cocky.
* BlondGuysAreEvil: More like Blond Guys Are the epitome of JerkJock, and he later proves to have shades of JerkWithAHeartOfGold at times
* [[spoiler:BrainwashedAndCrazy: As the Kanima, Jackson often seeks a Master to control him and everything that he does. So far, Jackson has been controlled by Matt and Gerard. Both of them have brainwashed Jackson into murdering and slaughtering innocents.]]
* BullyingADragon: Whenever he threatens Scott, Allison, or Derek.
* CompetitionFreak: Jackson is a highly competitive person by nature.
* CoolCar: As a rich kid, Jackson drives an expensive Porsche. And he has no problem with flaunting his expensive car, either.
* DarkAndTroubledPast: 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.
* DumbMuscle[=/=]DumbJock: While by no means a stupid human being, he tends to rely more on his athletic prowess than the other characters do.
* GoneHorriblyWrong: [[spoiler: Derek bit him; but instead of becoming a werewolf, his body rejected the bite and he became a reptilian like creature, the Kanima.]]
* TheHeavy: In season two [[spoiler: as the Kanima.]]
* HotGuysAreBastards: Jackson is seriously attractive and isn't breaking the stereotype that hot guys are major jerks with huge egos. Because Jackson is a jerk with a huge ego.
* HiddenDepths: Despite his JerkJock status, he's very much the OnlySaneMan at the start, and the only person the least bit curious about all the weird things happening to Scott.
* IJustWantToBeSpecial: 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.
* [[IceQueen Ice King]]: Jackson is very arrogant, cold, cocky and generally unfriendly.
* [[spoiler: ImplacableMan: As the kanima. Argent shot him, Derek slit his throat open, Allison planted an arrow in his skull... all for naught.]]
* InterspeciesRomance: With Lydia. Jackson was the Kanima (a lizard-like supernatural creature) and then was changed into a werewolf at the end of season two. Lydia is a regular human with no superhuman abilities.
* JerkJock: Jackson is the epitome of jerk who's specialty is being a good athlete. Jackson is an athlete who is cocky, arrogant and thinks he's better than everyone else. Jackson likes to be the star on the lacrosse field and doesn't take lightly to any competition. Since Scott gained his abilities, Jackson has become very jealous of him and the rivalry between the two has heated up even more than before. Jackson is the opposite of Scott, who is a LovableJock.
* JerkWithAHeartOfGold: He does care about his friends, and isn't in any way bothered by the fact that his best friend is gay.
* TheHeavy: In season two [[spoiler: as the Kanima.]]
* LonelyRichKid: Jackson is spoiled, rich and he gets everything he wants. The problem is, he doesn't seem to have that many friends. It's probably because he is suck a jerk for the majority of the time.
* [[spoiler: LoveRedeems: What do you know, it's the Kanima's weakness.]]
* MrFanservice: Like all of the other male characters, Jackson is physically attractive and yes, sometimes he's shirtless to have his body on display for a large proportion of the female viewing audience.
** ShirtlessScene: Jackson has had plenty of shirtless scenes like all of the other male characters (with the exception of Stiles of course) mostly when he is in the locker room.
* NotHimself: Once he figures out what Scott is, he begins to lose his mind.
* OnlySaneMan: He's the only one remotely confused by Scott's newfound athletic prowess.
* ParentalAbandonment: Jackson was adopted and didn't know who he is real parents were. Jackson not knowing his true parents contributed to his lack of identity.
* PutOnABus: Jackson did not return for season three. This is because of Colton Haynes departure. [[spoiler: Colton can now be seen on ''Series/{{Arrow}}'' as Roy Harper aka Red Arrow.]]
* SanitySlippage: Throughout Season 1, after Derek had scratched Jackson on the back of his neck leaving him wounded, Jackson started to feel off and started to display strange behaviour. It was mostly because Jackson suffered from aconite (wolfsbane) poisoning; this is because when Derek had scratched Jackson on the back of his neck, Derek was dying from the bullet which contained aconite wolfsbane.
** Also, after Derek had given Jackson the bite in the beginning of Season 2, his body rejected the bite and his body started to ooze black goo out of every orifice of his body. Because of bite going wrong, instead of becoming an actual werewolf, Jackson turned into a lizard like creature called the Kanima, who could be controlled by a Master (like Matt and Gerard) and commanded to kill people.
* ShipperOnDeck: For Danny and Matt.
* SpoiledBrat: Jackson has a very comfortable life and he gets everything he wants , most notably a nice car (he drives a Porsche).
* TenderTears: When he realizes just how far Scott will go for him.
* WoundThatWillNotHeal: Derek claws him in the back of the neck; this does not work out well for him.
