Teen Wolf is an American television series that currently airs on MTV. The series premiered on June 5, 2011, following the 2011 MTV Movie Awards.^[1] Teen Wolf is a supernatural drama series that follows Scott McCall (Tyler Posey), a high school student and social outcast that gets bitten by a werewolf and attempts to maintain a normal life while hiding his secret life as a werewolf and dealing with numerous supernatural dangers with the help of his trusted best friend Stiles Stilinski (Dylan O'Brien), and mysterious werewolf, Derek Hale (Tyler Hoechlin).

Casting announcements were announced in December 2010, with the rest of the main cast being Crystal Reed, Holland Roden and Colton Haynes.

Main characters

Scott McCall

Scott McCall, portrayed by Tyler Posey, is the series' main protagonist. Scott is bitten by a werewolf, transforming him into a werewolf as well. Using his new supernatural abilities, he became the co-captain of his high-school lacrosse team. He falls in love with Allison, who he later discovers to be part of an old werewolf-hunter family. Originally, seeing his new abilities as a curse, Scott wished to find a cure, but by the end of Season 2, he has accepted the abilities as a gift. After Jackson moved to London, he becomes the new captain of the lacrosse team.

Scott is extremely protective of his loved ones, particularly Allison, who he regards as both his greatest strength and his greatest weakness, and his mother, Melissa. He willingly risks his own life to protect those close to him, as well as anyone he deems innocent, and tries to balance the relationships he shares with those around him with his double-life and the dangers it presents. Scott lives with his mother, who works as a hospital nurse, his father is out of the picture, though this does not bother Scott and his mother, both of whom are content with just each other. Scott is closest to his best friend, Stiles. He is also, on occasion, the fourth member of Derek's pack. At the beginning of Season 3, Scott is an Omega werewolf. However, due to his eyes glowing red for a brief moment in a fight with the Alpha Pack, it was concluded that Scott has the latent potential of an Alpha werewolf, despite not having killed one. In the episode, "Currents," Deaton reveals that Scott might be in the process of becoming a "True Alpha," a rare werewolf that has become an Alpha werewolf by strength of character and willpower, rather than by conquest or murder– such an alpha is the greatest and rarest of all werewolves, and the real reason Deucalion and his alphas arrived in Beacon Hills. In the episode "The Overlooked", Scott tearfully joins the Alpha pack after Deucalion agrees to help him find his captured mother and Stiles' father. In the episode "Alpha Pact", Scott temporarily sacrifices himself with Stiles and Allison through a druid ritual to save their parents. In the mid-Season 3 finale "Lunar Ellipse", Scott helps Deucalion defeat the Darach and fully awakens his True Alpha werewolf powers and abilities.

"Teen Wolf: The Hunt", a Teen Wolf inspired social network game for Facebook, states that Scott was born on August 23. He likes guitars, horror films, and skateboarding, and is a fan of The Black Lips, Kids of 88, Blink-182, and Lost in Kostko (Tyler Posey's band in real life, in which he plays guitar and sings lead vocals).

Allison Argent

Allison Argent, portrayed by Crystal Reed, is Scott's love interest, and a descendant from a long line of werewolf hunters. She is at first unaware of Scott and Derek's lives as werewolves, and her family's werewolf-hunter life. By the end of season 1, she discovers that Scott and Derek are werewolves, though this does not halt her relationship with Scott, and learns of her family's werewolf-hunter life. In season 2, Scott and Allison are shown to be in a romantic relationship, while hiding it from her parents. Her grandfather decides that it is time she be trained as a true hunter, which in her case, means being groomed to eventually succeed her mother as the family's strategist. She helps Scott and Stiles go up against the Kanima. She is later corrupted by Gerard, who emotionally uses the death of her mother to use her to attack innocent werewolves, but she soon realizes her mistake. By the end of the season, Allison breaks up with Scott. At the start of season 3, Allison has had not contact with Scott whatsoever in the four months following the final encounter with the Kanima, having spent the summer at her family's ancestral home in France with her father. She and Chris agreed to lay their family legacy aside and return to Beacon Hills to finally start a real, normal life. Although she and Scott are no longer together, it is evident that she still cares deeply for him. In violation of her agreement with her father, she begins to help Scott and the others fight the Alpha pack. Allison and Isaac also mend fences, so much so that he is chosen as her tether when she must undertake a dangerous ritual to find her missing father. In the midseason finale, Allison and her father come out of retirement and decide that, instead of hunting those that hunt them, they should protect those that can't protect themselves.

Allison is caring, sweet, and agile with a natural talent for archery. Unlike her grandfather Gerard and aunt Kate, both of whom murdered werewolves regardless of their innocence, she believes in the Argents' hunting code ("Nous chassons ceux qui nous chassent", which is French for "We hunt those who hunt us") like her father, Chris Argent. Her father soon starts Allison's training to be a werewolf hunter. She hates the feeling of being weak and uses her training to take care of herself in dangerous situations.

"Teen Wolf: The Hunt", a Teen Wolf inspired social network game, states that Allison was born on March 19 in Elkhorn, Wisconsin. She likes archery, running, and Unicef, and is a fan of Karmin, Arcade Fire, Florence and the Machine, and Vampire Weekend.

Stiles Stilinski

Stiles Stilinski, portrayed by Dylan O'Brien, is Scott's best friend and the show's comic relief. He is shown to be intelligent, if not somewhat impractical about things, curious for his own sake, and caring with a sarcastic nature. The show alludes to him having attention deficit hyperactivity disorder through references to his Adderall use, which lends to his fidgeting gestures and frequent flailing.^[2] Stiles provides comic relief to the otherwise dramatic events that plague him and Scott. His eagerness to help and his caring nature often puts him in dangerous situations.

Stiles holds an intense but unrequited love for Lydia Martin, having harbored a crush for her "since the third – frickin' – grade". Stiles also shares a very close relationship with his father, Sheriff Stilinski; his mother Claudia died when he was a little boy. Stiles is shown to be insecure about his mother's death, blaming himself for it and thinking it will come between him and his father. He wishes he could help and protect his father in some way, feeling he can't because he does not have supernatural abilities. "Stiles" is not his first name; creator Jeff Davis has stated that Stiles' real name hasn't been revealed. It is canon that Stiles' first name was his maternal grandfather's name. In Season 3, Stiles is shown to be working with Lydia to figure out who is the culprit behind the mysterious sacrifices going on in Beacon Hills. He eventually sacrifices himself temporarily with Scott and Allison to save their parents. He is finally reunited with his father at the end of the mid-season finale with the new burden of having a "darkness" forever shrouding his heart, like a tattoo.

"Teen Wolf: The Hunt", a Teen Wolf inspired social network game, states that Stiles was born on April 8.^[3] He likes drumming, snowboarding, and the New York Mets. He is a fan of the bands The Ramones, The Offspring, Mumford and Sons, All Time Low and Slow Kids At Play (Dylan O'Brien's band in real life, in which he plays drums).

Derek Hale

Derek Hale, portrayed by Tyler Hoechlin, is a werewolf by genetic lycanthropy, passed down through his family line. When he was 15 years old, he fell in love with a girl named Paige. Wanting to be with her forever, Derek came up with the idea of turning her into a werewolf. He asked Ennis, an Alpha werewolf, to give her "the bite". After Ennis bites her, Derek, hearing Paige's painful screams, attacked Ennis and realized he was too late to save her. Knowing that she would die instead of transforming, Derek sadly breaks her spine to end her suffering. The killing of an innocent caused his werewolf eyes to change from yellow to blue, darkening his soul. His family was later killed in an arson that burned their home while he and his older sister Laura Hale were in school, leaving only his uncle, Peter Hale, to survive. In the Season 1 finale, Derek becomes the new Alpha werewolf after killing Peter, the previous Alpha, to avenge Laura's death.

When he was a teenager Derek was once like Scott, he was naïve, unbearably romantic, profoundly narcissistic, after the death of his first love Paige, he was never the same after that, he originally trusted people too quickly and too easily, but after he was betrayed by Kate, his clandestine lover, he no longer trusted people in general, except members of his remaining family, (excluding his uncle Peter), and keeps his feelings to himself, because he doesn't know how to share his feelings with others. According to Peter, Derek's best ally has always been anger because he lacks a heart. Despite being competitive, cold, easily aggravated, and distrustful of people in general nature, Derek genuinely cares for Scott McCall and his friends and always tries to keep them out of danger (reluctantly Stiles and excluding Allison). However, he strongly disapproves of Scott's relationship with Allison Argent, because her influential family are werewolf hunters. As an Alpha werewolf, Derek exhibited pride and assembled himself a pack, consisting of three students from Beacon Hills High who all have dark backgrounds just as he does. Derek is as hostile and cold towards Allison as he is towards other members of her family, with the exception of her father somewhat, and this is because she attacked his pack and tried to kill him. He does not trust her, refuses to work with her or accept any help from her. Derek generally cares about what happens to Scott, but he does not approve of his relationship with Allison, partly due to her coming from a family of werewolf hunters and being a former werewolf hunter herself, When Scott was interfering in his business of turning people into werewolves, he beat Scott up to teach him a lesson and not to interfere in his business next time. By Season 3, he has gained respect for Scott, and has grown to trust him a little. Derek does not get along with Stiles at all, and has no respect for him, often giving him death threats with no intention of going through with them. His love interest in Season 3 was Jennifer Blake (BHHS's English teacher), whom Derek saved from Boyd and Cora (his younger sister whom Derek thought died in the fire). Eventually he leaves Beacon Hills with Cora in the mid-season finale after suffering through the deaths of his Beta werewolves (Boyd and Erica) and being betrayed by Jennifer (who turned out to be the Darach, a powerful evil druid). He is no longer an alpha werewolf, having given up that power and ability in order to save Cora from death.

Creator and producer Jeff Davis released a statement on Twitter insinuating that Derek is older than the audience thinks, and more will be revealed about him in season 3, premiering in 2013. His birthday is 7 November.^{[citation needed]} A 15-year-old Derek Hale was shown in the 8th episode of Season 3, played by Hunger Games teen actor Ian Nelson.^[4][5]

Lydia Martin

Lydia Martin, portrayed by Holland Roden, is Beacon Hills High's most popular female student. Lydia at first appears to be the archetypal high school queen bee, but in reality she is surprisingly caring, especially about her friends, and extremely intelligent, excelling in math and science. She is well aware of Stiles's feelings for her, but does not reciprocate them. She shows her warm nature in the first episode by befriending Allison on her first day at school. Her love interest is Jackson Whittemore; although in the first season she makes it apparent she is merely dating him due to his high social status, it is later revealed that she cares more about him than she lets on and may even be in love with him. The two share a conflicted, but close relationship. At the start of the series, she gives the impression of barely knowing who Scott and Stiles are, only expressing interest in Scott after he is turned and shows skill at lacrosse. In season 2, she spends more time with them (in part because they are amongst the few people who don't believe she is crazy). By season 3, she has come to care deeply for them, to the point where she rescued them from a fiery death when Scott had been driven mad through wolfsbane poisoning.

At the end of season 1, Lydia was bitten by the Alpha werewolf Peter Hale but neither dies nor turns. Instead, she was revealed to be immune. This goes against her in season 2 when Peter Hale used her immunity to come back to life. In the beginning of season 2 Lydia imagines pulling out an arm in the bathtub, and, freaking out, she escapes the hospital and runs around in the woods naked for two days. Lydia was determined to be immune to the Kanima's venom, and thus assumed to be the Kanima herself, although it was later revealed to be Jackson. Lydia suffered hallucinations throughout the season, which were eventually revealed to be caused by Peter, who somehow used her to return to life. As a result, she learned bits and pieces of the truth of what was happening, though neither Allison nor Stiles were willing to tell her the whole truth just yet. In the season 2 finale, Lydia faces the Kanima and successfully coaxes it to transform back into Jackson, by holding up the house key Jackson had given her when they were together. When Jackson asks if she still loves him, she responds that she does.

By Season 3, Lydia has been brought up to speed on the subject of werewolves, although some of the other characters occasionally forget that she is now in the loop (for example, nobody told her that Aiden and Ethan were alphas until after she started seeing Aidan) and offers an update on the now-absent Jackson upon Allison's return. She enters into a recurring liaison with the alpha Aidan as a distraction, initially to distract herself from Jackson, and later to distract Aidan from Scott's activities. Lydia displays a strange connection to the events occurring in Beacon Hills this season, being mysteriously drawn to the last locations of several of the sacrifices. Since Scott, Isaac and Allison are preoccupied with the Alpha pack, Lydia reluctantly joins forces with Stiles to figure out who is really behind the sacrifices. In the episode, "The Girl Who Knew Too Much", it is revealed that the cause of her mysterious supernatural abilities stems from the fact that she is actually a banshee or a wailing woman. The extent of her abilities are unknown, but she is learning to control and channel them to prevent any further deaths.

Teen Wolf: The Hunt, a Teen Wolf–inspired social network game, states that Lydia was born on March 23. She likes Mu Alpha Theta, figure skating, yoga, and astrophysics, and is a fan of Madonna, Calvin Harris, Kids of 88, Muse, and Kat Graham.

Jackson Whittemore

Jackson Whittemore, portrayed by Colton Haynes, is the former captain, now former co-captain, of the Beacon Hills lacrosse team. He has a competitive and aggressive nature, which shows through hostility towards people who best him. The show implies that he wants to make others proud of him. Despite his abrasive personality, he cares about his friends and dislikes hurting them. He is insecure about his adoption and the fact that he does not know his real parents, leading him to be unable to see his adoptive parents as his true mother and father. His birth mother had died on June 14 while pregnant, meaning he had been pulled out of his dead mother's womb.

Though Derek gives Jackson the bite, his body rejects it in season 2 and Jackson instead becomes the Kanima, a murderous shapeshifting creature that is a weapon of vengeance. The Kanima seeks a master who wishes to exact revenge on others to control it, revealing that as the Kanima, Jackson's every move is controlled by someone else. Jackson does not know that he is the Kanima, nor does the Kanima side of him know that it is Jackson. It is revealed that he became the Kanima because he is an orphan, meaning he lacks an identity. He can be saved by a person with whom he shared a true bond; in Jackson's case, this person is Lydia. Through Lydia's selflessness in the finale, Jackson heals and finally becomes a werewolf, however, with blue eyes rather than yellow. This is because when a werewolf kills someone innocent their eyes turn from yellow to blue, other Werewolves who have this feature are: Derek and Peter Hale.

"Teen Wolf: The Hunt", a Teen Wolf inspired social network game, states that Jackson was born on June 15. He likes Porsche, Golden State Warriors, USC Trojans, and the San Jose Sharks, and is a fan of Wiz Khalifa, Nicki Minaj, Drake, and Gym Class Heroes.

In the Season 3 premiere, Lydia revealed that Jackson was trained by Derek to control his werewolf powers/his animal side, and then later moved to London.

Isaac Lahey

Isaac Lahey, portrayed by Daniel Sharman, is a formerly tormented teen and lacrosse player who lived across the street from Jackson. Isaac was abused by his father, who tortured him by often locking him in their basement freezer. Isaac is turned into a werewolf by Derek and becomes the first member of Derek's pack. He wished to become a werewolf to feel powerful and confident after a long history of physical and mental abuse from his father, who is murdered by the Kanima in the Season 2 premiere.

Isaac was the first of Derek's Beta werewolves to gain control of his animal side during the new full moon, and has good intentions and a warm heart. At first, Isaac did not like Scott and did not trust him, due to the fact that he was interfering in Derek's business of turning people into werewolves, and believed Scott was a loser because he wondered how Scott survived so long without a pack. Nevertheless, he eventually trusted Scott when he realized Scott has good intentions, and became friends with him. Among the dangerous events throughout Season 2, Isaac sides with Scott, revealing that he trusts him and holds onto Scott's friendship because he doesn't have anyone there for him. He helps Scott against Gerard and stays as a part of Derek's pack instead of following Boyd and Erica, who want to leave Derek for their own safety. It is implied that Isaac looks up to Derek in the way that he couldn't look up to his own father. Creator Jeff Davis has stated that Isaac will be a big part of Season 3, premiering in 2013, and will possibly threaten Scott and Stiles's friendship with his own close bond that he shares with Scott. Isaac did not interact much with Allison throughout Season 2, but in the Season 2 finale, after she shoots an arrow at him and stabs him with Chinese ring daggers, Isaac develops a grudge against her, and has not forgiven her. When Ethan and Aiden set him up for beating up one of them, he wanted to avoid spending afternoon detention with Allison. Then, when Ethan and Aiden locked both him and Allison in a supply closet, (due to him being afraid of tight spaces) Isaac involuntarily transformed into his werewolf form. Despite Allison trying to help calm him down, Isaac lost control and would have killed Allison, if it was not for Scott's intervention. He accidentally scratched her, having a small breakdown and apologizing profusely after Scott intervenes, but Allison tells Scott it wasn't his fault and lets Isaac know she wasn't blaming him or mad at him. They then work with Scott to get even with Ethan and Aiden for locking Isaac and Allison in a supply closet. Sometime after that, Isaac has forgiven Allison for shooting an arrow at him and stabbing him with Chinese ring daggers. Isaac has developed romantic feelings for her. The first episode of season 3 opens with Isaac getting chased by the twin Alphas. A mysterious girl saves him, but she and Isaac are injured and sent to the hospital. Melissa McCall tries to call Derek for help as Isaac's wounds are already healing and he's supposed to go into surgery. When Derek cannot be reached, Isaac asks Melissa to call Scott. Before Scott can get to the hospital, Isaac is drugged and kidnapped by the Alphas. He is then rescued by Derek and Scott. After Derek heals him, he awakes, asks where the girl is, but the others have no idea what he is talking about. Isaac allows Peter to access his memories, but is unable to get enough information about the whereabouts of Boyd and Erica. Dr. Deaton helps Isaac remember where to find Boyd and Erica by slowing down his heart in a tub of ice and discovers that Erica is already dead, while Boyd and another werewolf named Cora are still alive. He later participates in helping capture Boyd and Cora, teaming up with Chris Argent and Scott. During the time of trying to save Boyd and Cora, he shares an eye to eye moment with Allison, hinting possible feelings between them. Throughout the season, both Allison and Isaac have moments that strongly hint towards strong romantic feelings for each other, even when Allison allows him to comfort her after her father is kidnapped. He is shown to despise the Alpha twins, blaming them for the death of the girl who saved him, and tries to get them angry in any way possible, along with the help of Scoot and Allison. After being thrown out of Derek's loft, he lives with Scott for the time being. Isaac later participates in the pack's battle against the Alpha pack. After Boyd's death, he now stands as the only bitten Beta werewolf of Derek's pack. Isaac later becomes fed up over the deaths of Boyd and Erica, and confronts Derek about how people always die around him and how he only cares about power. He also starts to have more respect for Scott than Derek, seeing that Scott is willing to defend everyone and not to kill. During the mid-season finale, he helps Allison, Stiles, and Scott find their parents. By the end of the finale, Isaac leaves Derek's pack after Scott becomes a True Alpha werewolf and Derek leaves Beacon Hills with Cora. He is now the presumed beta of Scott's pack and the love interest of Allison.

"Teen Wolf: The Hunt", a Teen Wolf inspired social network game, states that Isaac was born on September 22, and likes lacrosse and BMX. He is a fan of M. Ward, Belle and Sebastian, Coldplay, and Feist.

Recurring characters

Werewolves

• Laura Hale (Haley Roe Murphy) (Season 1)

Laura was Derek's older sister and also a born werewolf. She survived the Hale Fire because she was in school at the time. It is unknown if the fire caused her to become the Hale family Alpha werewolf once her mother Talia^[6] died, or if she already held that title prior to the fire. Unlike other Alpha werewolves, Laura was able to transform into a fully formed canine wolf while in her Alpha werewolves state. It is assumed she inherited this ability from her mother when she died. Sometime after the fire, Laura returned to Beacon Hills to investigate who was responsible for the fire. She was able to uncover some information, but was killed by her uncle Peter before she was able to find out the whole truth. The discovery of half of her body in the Beacon Hills Preserve sparked the plot for the series. Strangely enough, Kate Argent (before her death) admitted to Derek that she was the one who cut Laura's body in two, which Derek confirmed as true by listening to Kate's heartbeat to verify that she was not lying, She was the first female Alpha and the first female werewolf to make an appearance in the series.

• Peter Hale (Ian Bohen) (Seasons 1 - 3)

Peter is Derek's maternal werewolf uncle, and was the main antagonist in the first season. In the Hale Fire, he was badly burned and assumed to be paralyzed. In the episode "Wolf's Bane", he was revealed to be the Alpha werewolf who had bitten Scott and killed many people directly involved in the Hale Fire. In the Season 1 finale, he kills Kate Argent, the final person directly involved in the fire, and was burned alive by Scott, Allison, Stiles, and Jackson, before getting his throat slashed by Derek.

In Season 2, he uses Lydia in a yet unexplained manner to return to life, by using Derek's power as an alpha to come back. Show Executive Producer Jeff Davis confirmed that Peter Hale reverted to a Beta werewolf class once he was resurrected, and is now a member of Derek's pack.^[7] Peter's actual motives for returning are yet to be revealed. He appears to have an uneasy truce and partnership with Derek and his pack. He is also the fifth member of Derek's pack. He also starts playing a larger role in season 3. When he was younger he was slightly a manipulator, and slightly a liar, but he cared about his family, after most members of his family were murdered by Kate Argent, and her co-conspirators, and after half of his face was burned off, he was traumatized by it, by the time he came out of his coma, he was a completely different person, Peter is a sociopath, vengeful, intelligent, sarcastic, witty, talks a lot possibly to explain himself, he always has a backup plan for everything, does not like being caught by surprise, only desires power to get revenge on his family, but when he killed his niece Laura to get it, he regretted it and has remorse for his actions, he has no ill feelings toward his nephew Derek for killing him, and did not try to kill his nephew in order to become an Alpha werewolf again.

In Season 3, Peter is shown to care about his remaining family members Derek and his niece Cora, while also retaining some of his selfish parts as well. He helps Derek and the others out on special occasions, even helping Scott fight the Alpha Twins (Aiden and Ethan). He is also shown to be somewhat impaired due to resurrecting from the dead in Season 2 and can only use some of his abilities. He tells the story of what happened to Derek to Cora and Stiles, explaining that Derek was forced to kill his first love and in turn made his werewolf eyes blue. However, during the course of his perspective, it is revealed that Peter lied about some of the story, which Stiles catches onto. In the mid-season finale, Peter kills Jennifer, who reveals his plans to kill Scott to become an Alpha werewolf again.

• Boyd (Vernon Milton Boyd, IV)^[8] (Sinqua Walls) (Seasons 2 - 3)

Boyd was a shy loner at Beacon Hills High School and works at the Beacon Hills Ice Rink. In the second season, he is the third member of Derek's pack, although he's the fourth teenager that Derek had bitten. For most of the season, he was Derek's right-hand man and physically the strongest and largest Beta werewolf of the pack. He was perhaps the most grounded teenager on the show. Scott stated that while Boyd is stronger than him, he is actually faster than the large beta werewolf. He was close to Erica, and left with her to find another pack at the end of Season 2, becoming an Omega werewolf in the process. After a short altercation with and capture by the Argents, he and Erica attempt to flee Beacon Hills, but are trapped by the Alpha Pack, leaving his fate uncertain.

In Season 3, it is revealed that Boyd and possibly Erica were alive and had been held captive by the Alpha pack for four months in the abandoned Beacon Hills First National Bank. During this four-month period, he and Erica had a heart-to-heart about them possibly becoming stronger during the lunar eclipse. Erica tries to fight back against the Alphas and is killed. Boyd and Cora, Derek's younger sister, were refrained from fully transforming during the full moons, causing their rage and bloodlust to build up inside. Upon being found by Derek and Scott, both of them lost all control and escaped into the woods to kill whomever they came across. They were later subdued by Derek, with assistance from Scott, Isaac and Chris Argent. Boyd returned to school still upset over the death of Erica, who he claimed was his only friend. He participated in the pack's battle against the Alpha pack and is easily defeated by them. Knowing that Kali would eventually come to kill Derek to "avenge" Ennis' death, Boyd cleverly came up with a way to weaken Kali. During Derek's fight with Kali, Boyd is accidentally killed by Derek, which caused the latter to absorb Boyd's power and see a vision of Erica's death. Before dying he comforts Derek by telling him to not blame himself for everything that has happened and finishes by saying that the sensation of the full moon was worth everything.

• Erica Reyes (Gage Golightly) (Seasons 2 - 3)

Erica was a student at Beacon Hills who suffered from epilepsy. At the hospital after a seizure, Derek gave her the bite, promising that her illness would go away. In the second season, Erica was the second member and the first female werewolf of Derek's pack. She was the second female werewolf to make an appearance in the series. She changed remarkably, becoming more confident and stylish. She revealed that she used to have a huge crush on Stiles, but he never noticed her. Erica was shown to be close to both Isaac and Boyd throughout the season, and repeatedly antagonized Allison. Erica had hit on Scott twice, hinting that she had romantic feelings for him. At the end of Season 2, she and Boyd left Derek to find a new pack, becoming Omega werewolves in the process. They were captured by Gerard, but were freed by Chris. While fleeing again, Erica and Boyd were trapped by the Alpha Pack, leaving their fate uncertain.

During Season 3, it is revealed that she and Boyd where held captive for four months by the Alpha Pack in the abandoned Beacon Hills First National Bank. During captivity, she and Boyd had a heart-to-heart about them possibly becoming stronger during the lunar eclipse. She later tried to attack Kali, but was killed in the process. Isaac later reveals that he found them and also Erica's body before being captured and escaping. After Derek finds Erica's body, he mourns her death and carries it out of the bank.

• Deucalion (Gideon Emery) (Season 3)

Deucalion is the Alpha Pack leader and one of the main antagonists of Season 3. In the past, Deucalion and his original pack wanted to avoid bloodshed to make peace with the Argents. He and three of his Beta werewolves were instead tricked and ambushed by Gerard, who not only killed Deucalion's Beta werewolves, but his own men who wanted peace with the werewolves. He later blinded Deucalion in an unsuccessful attempt to kill him. With the help of Dr. Deaton, Deucalion's eyes healed physically, but his sight didn't return. This discovery coupled with Gerard's betrayal enraged Deucalion. Marco, one of Deucalion's Beta werewolves, took this opportunity to try and kill Deucalion to become the Alpha werewolf of their pack. Deucalion, however, realized he could see as a werewolf and killed Marco, absorbing his power. Sometime after, he killed the remaining members of his pack and formed his Alpha Pack with Ennis, Kali, and the Twins (Aiden and Ethan). In order to form the pack, he ordered all of his members to kill every single person in their pack, including their emissaries. Deucalion is now sociopathic, arrogant, vain, and not above killing members of his alpha pack (which he does to Ennis), if they are useless to him. He has no remorse for his actions. He is revealed to have bitten a member of the Argent family, Alexander Argent, which led to his suicide. It is later realized that Deucalion knows that Scott is a "True Alpha" werewolf (a rarity among werewolves) and is after him, not Derek. With the new killer called the Darach killing people, Deucalion became interested and had his followers hunt it down. He fears the Darach because it used to be a druid, or an emissary, who can call upon powers from sacrifices. After finding out that the Darach is Jennifer, Kali's old emissary, Deucalion tried to have her killed. Scott later joins Deucalion's pack in "The Overlooked" in order to look for his kidnapped mother, however when Deucalion tries to kill his emissary Marin Morell, Scott realizes the danger he is in.

Deucalion possesses abilities far greater than that of an average alpha, so great that he is able to command a pack of exceptionally strong alphas with both fear and respect. Unlike most werewolves, Deucalion's transformed state has more demonic traits than wolf ones. His skin turns dark blue/grey and his facial structure changes making him look more demonic and unlike other wolves, Deucalion has no visible hair growth. His strength is so great that he can easily best Jennifer, powered by the nemeton, and Derek, in his beta state, without suffering damage.

During the lunar eclipse, Deucalion temporarily loses his powers and Jennifer is to be able to defeat him. After being beaten to a pulp by Jennifer and having his blind eyesight healed by her in the mid-Season 3 finale, Derek and Scott let him go on the condition he tries to maintain peace between werewolves and humans. His current whereabouts remain unknown. With no pack left and presumably no emissary, his status as an Alpha is also questionable.

• Ethan and Aiden (Charlie Carver and Max Carver) (Season 3)

Ethan and Aiden are twin Alpha werewolves and were members of Deucalion's Alpha pack. They were originally abused Omegas in a pack of werewolves in which Ethan described them as being killers, their Alpha werewolf being the worst one. After meeting Deucalion, they were taught how to merge and control their combined form. They then hunted down and killed each member of their pack and became Alpha werewolves after killing their original Alpha werewolf together. They were the youngest members of Deucalion's alpha pack and possess the ability to morph into one giant Alpha werewolf together. Aiden is straight with an interest in Lydia Martin - Ethan is gay and interested in Danny Mahealani. Aiden is aggressive, violent, brutal, impulsive, and shows no remorse for his actions, but he has good intentions, Aiden finally turns on Deucalion and his Alpha Pack, after Kali threatens to kill Lydia, and he also realizes what they are doing is wrong, and he did not join Deucalion's Alpha Pack to kill innocent people. Ethan, by contrast, is cold, intelligent, calculating, calm, and shows a more remorseful side, and has good intentions, Ethan finally turns on Deucalion and his Alpha Pack, because he realizes what they are doing is wrong, and he did not join Deucalion's Alpha Pack to kill innocent people. Aiden and Ethan originally seduce Lydia and Danny to try and get leverage on Derek's pack members, but Ethan's feelings for Danny turn out to be genuine, to the point where he is willing to meet Scott halfway. Ethan betrays the pack in the mid-Season 3 finale to help Derek and Cora escape from Kali. Aiden develops feelings for Lydia, which causes Kali to question his loyalty. Later after Lydia, Deaton and Cora save the lives of the twins, they both willingly leave Deucalion's Alpha Pack and presumably work alongside Scott and Isaac. They are the first twin Alphas and the first twin werewolves to make an appearance in the series. Their ability to merge together as one giant Alpha werewolf was taken away after Jennifer snapped their merged neck.

• Kali (Felisha Terrell) (Season 3)

Kali was an Alpha werewolf and part of Deucalion's Alpha Pack and is nearly barefoot all the time. She was arrogant, sadistic, cowardly, aggressive, and had no remorse for her actions.

She was the second female Alpha and the third female werewolf to make an appearance in the series. She was responsible for the death of Erica and partly responsible for the death of Boyd. She was shown to be close to Ennis (apparently, he was her mate) as she looked worried over his severe condition after his fight with Derek and she took his death very hard. In the episode "The Overlooked", it was revealed that Kali used to be kind and had remorse for her actions, and her emissary was Julia Baccari (Jennifer Blake´s real name). Kali attempted to kill her, as part of killing her entire pack in order to join Deucalion's Alpha pack, but was unable to in the end.

• Ennis (Brian Patrick Wade) (Season 3)

Ennis was an Alpha werewolf and part of Deucalion's Alpha Pack. He was the largest member and a pure force of brutality. His immense strength combined with his skillful fighting knowledge made him a powerful adversary in a fight. Despite this he was no match for Derek in their first encounter, in their third and final encounter, he was able to go head on with Derek, but he was not able to overpower him, he most definitely would have been killed by Derek, if both of them was not seriously injured, where they were forced to leave in order to recover from their injuries. In the past, one of Ennis's Beta werewolves accidentally killed two werewolf hunters and was killed in retaliation. This enraged Ennis and caused him to seek out a new member for his pack. After being asked by Peter, Ennis bit Derek's girlfriend Paige to be on good terms with Talia Hale and to add a new member to his pack. She died instead. Like Deucalion and Kali, Ennis killed his entire pack and emissary. He tried to kidnap Isaac at the hospital, only to be stopped by Derek and Scott. After breaking into Derek's loft, Ennis easily subdued Cora while Deucalion explained his proposition to Derek about joining their pack. During Deucalion's Alpha pack battle against Derek's pack, Ennis was severely injured by Derek and Scott, which caused Kali and Aiden to seek out Dr. Deaton for help. He was later killed by Deucalion after he couldn't heal himself. He originally cared about his original pack, being vengeful when he wanted revenge against the Argents for killing one of his beta werewolves, who accidentally killed two of their werewolf hunters; and he was heartbroken because he considered that young man to be family to him. Sometime after that, he killed the remaining members of his original pack.

All three were held captive in the abandoned Beacon Hills First National Bank. During this period, Erica died and Boyd and Cora were refrained from fully transforming during the full moons, causing their rage and bloodlust to build up inside. Three months later, upon being found by Derek and Scott, Cora and Boyd lost all control and escaped into the woods to kill. They were later subdued by Derek, with assistance from Scott, Isaac and Chris Argent. She is also the sixth member and the second female werewolf of Derek's pack. Cora is impulsive, trigger-happy, short tempered, vengeful, and a bit of a tomboy. Like her older brother Derek, she gives death threats to people; of course, like her older brother, she has no intention of going through with them. She was shown to be close to Boyd as she breaks down in tears and cradles his body after he dies. Cora tries to avenge Boyd's death by killing Aiden, but fails to do so and is put in the hospital from the blow in the head Aiden gave her.

After seeing a supposed victim of Boyd and Cora's rampage, he assists Scott, Derek, and Isaac, in finding and capturing them.

Gerard tells Chris that the Alpha werewolf that bit him was Deucalion. Throughout the third season, Chris is shown to be taking part in the recent activities with the Alpha Pack and the killings by the Darach. It is later revealed that Chris has been hunting the Darach for some time and knows about Allison's involvement in helping Scott, Stiles, and Isaac.

Perhaps as a result, she did not assume a leadership role in the family as most female Argents did. Kate and Derek Hale had a romantic/sexual relationship, only to betray him and set the Hale Fire. She was close to Allison, but was not above using her, and was the one who told her about the supernatural world. She was eventually killed by Peter Hale as revenge for the Hale Fire.

When Derek changes his mind about having Paige "turned", he tries to stop it but is too late. Paige's body begins to reject the bite, which causes her extreme pain. Derek, unable to see her in so much pain, sadly broke her spine to end her suffering. This caused his werewolf eyes to change from yellow to blue as a sign he has taken an innocent life.
