	— Liam to Hayden in Memory Lost

Liam Dunbar is a former supporting character and a current main character on MTV's Teen Wolf.

Biography

Liam previously attended Devenford Preparatory Academy, but he was expelled at the end of his first semester of freshman year and transferred to Beacon Hills High School to join the lacrosse team there. It was through lacrosse that Liam met Scott McCall and Stiles Stilinski, particularly when the former saved his life after a Wendigo named Sean Walcott threw him off of the roof of the hospital. However, to do so, Scott had give Liam the Bite, and he ended up successfully surviving the process to become a Beta werewolf.

The transformation initially terrified him due to fear that his parents would find out and look at him like he was a monster, but Scott eventually convinced him that being a werewolf and being a monster were very different things. Liam later proved to be an exceptionally strong werewolf despite being a newly-bitten Beta, but the anger that made him so much stronger also made it much harder for him to control his transformations. Even still, after over half a year of practice and training, Liam has become a very proficient werewolf, though he still has difficulty controlling himself on full moons, especially during supermoons.

After Season 4 and throughout Season 5, Liam grew closer to all of the members of his new pack, especially Scott and Stiles, but he was initially afraid to confess his new supernatural identity to his best friend Mason Hewitt. However, Liam eventually overcame this fear after he was forced to shift in front of him, and he was relieved when Mason accepted his confession with excitement and joy. The two then helped the McCall Pack deal with the Dread Doctors and their newly-created Chimeras, but unbeknownst to anyone, Theo Raeken, a Chimera masquerading as a true werewolf who claimed to have returned to Beacon Hills after a long absence to join Scott's pack, was actually manipulating all of the members to turn against Scott, Liam included.

When Liam's new girlfriend Hayden Romero was near death due to a mercury overdose and Scott refused to give her the Bite out of fear of killing her, Theo used the anger Liam already felt and the effects of the impending supermoon to convince him to kill Scott so that he could become an Alpha and give Hayden the Bite himself; Liam was too overwhelmed with anger and grief to realize that Theo needed Liam, as Scott's only bitten Beta, to kill Scott and steal his powers so that Theo could then kill Liam and take the powers for himself. Though Liam's attempt to kill Scott failed, the two were estranged for some time before they finally reconciled after both realized the extent to which Theo had manipulated everyone. Ever since, Liam's relationships with Scott and the pack at large are stronger than ever, and they were able to defeat the Dread Doctors, Sebastien Valet/the Beast of Gevaudan, and Theo himself as a team.

Liam is in a romantic relationship with Hayden Romero and is best friends with Mason Hewitt and Scott McCall. Liam is also a member of the McCall Pack.

Early Life

Little is known about Liam's very early life, including the names of his mother and father. However, it is known that Liam was raised by his mother and step-father, a Harvard-educated doctor at Beacon Hills Memorial Hospital named Dr. Geyer, and he battled significant anger issues in his childhood. (("Muted")) According to Liam, his step-father told him that children deal with anger in one of two ways: by hurting themselves, or by hurting someone else. (("Orphaned")) Liam typically dealt with his anger by hitting things, thereby hurting himself, but also occasionally took his anger out on others by getting into physical fights. However, when he started his freshman year at Devenford Prep, his lacrosse coach benched him for getting too many red cards, and Liam was so overwhelmed with rage that he destroyed his coach's car with a crow and carved "THIS IS YOUR FAULT" across the side. (("The Benefactor")

This reaction got him expelled from school and sent to a psychologist for an evaluation. The psychologist diagnosed Liam with intermittent explosive disorder, otherwise known as I.E.D., and prescribed him risperdol to manage the symptoms. However, the medication caused Liam to be so tired that he couldn't play lacrosse, one of his few outlets for his anger, and he eventually quit taking it completely. Afterward, Liam enrolled at Beacon Hills High School for his second semester of freshman year, just in time for lacrosse try-outs. (("I.E.D."))

When Liam was in sixth grade, he got into a fist-fight in the hallway of his school with another male student. Hayden Romero had the misfortune of walking into the hall at the wrong time and accidentally got punched in the face by Liam, who broke her nose in the process. Furious at Liam, Hayden punched him in the face and broke his nose to get back at them. Unfortunately for both of them, this fight occurred on school picture day, and both Hayden and Liam had to have their picture taken with black eyes and taped-up noses, causing the two to develop a rivalry that lasted until their sophomore year of high school. (("Parasomnia")), (("Required Reading"))

Throughout Teen Wolf

After seeing what has just occurred, Malia Tate gets up in the stands demands a do-over, she puts $10 on Scott and Stiles, Coach excepts her offer and tells Liam to go again.

He then receives a text from Mason asking where he is at, Liam tells Mason about the party. As they arrive Liam begins breathing heavily, he's becomes suspicious as to why there aren't more people, once he enters the house, Stiles tells him its an intervention.

He has been filled in on their supernatural status, to Scott he says werewolf, to Malia he says werecoyote, to Lydia he says banshee and to Kira he says fox, Kira says the correct term is kitsune. He looks to Stiles wondering what he is, Stiles saya that "for a little while I was possessed by an evil spirit. It was very evil". Liam says what are you now, and Stiles says "better". He notices the chains on the table wondering if those are for him, Malia says they are for her and she makes her eyes glow blue. He is taken back and demands to know how she did that, Scott says he'll learn after he gets through this first full moon.

In I.E.D., Liam and Mason are working out in the weight room, Liam is bench pressing 180 pounds, Mason tells him about how he allowed Garrett to use his hoodie but it was never returned. As Mason continues to talk, Liam adds more weight, Mason then accuses him of acting strangely, Liam doesn't care and he adds on even more weight which leads Mason to ask if he's on steroids. Mason wonders if this has anything to do with the upcoming lacrosse game, Liam initially says no but he then learns that they will be playing his old school, Devenford Prep. He becomes enraged, enters the locker room in search for his lacrosse stick and discovers that Derek Hale has it, he snaps the stick in half. Liam instinctively attacks; however, he is no match for Derek who slams him against the locker with one hand.

Scott and Stiles grab Liam and take him to the showers in the boys locker room where he eventually calms down.

Liam explains to them that the car he destroyed belonged to his coach, he did it after being benched for an entire season. His anger was so out of control he had to be sent to a psychologist who diagnosed him with I.E.D. He says that he's suppose to take a medication called Risperdal but he refuses to because it makes him too tired and prevents him from playing lacrosse. Scott suggests that Liam sit this game out but he refuses, they explain to him that one of the assassins is likely on the lacrosse team and that same person is the one who ordered the keg at Lydia's party.

It reminds Derek that a Beta can become an Alpha but an Alpha can also become a Beta, Liam wonders if an Alpha can become an Omega and Derek says yes. Derek further explains to Liam that Alpha, Beta, Omega is the family mantra, they repeat it over and over, each time gaining more control, Liam tries to but it fails.

He then breaks the other cuff and tries to attack Derek, with the Hale mantra not working, Stiles offers another, he asks Liam "What three things cannot long be hidden?", Liam says "The sun, the moon, the truth", this mantra proves effective and he regains control.

They enter the temple in search for Scott but Liam, Peter and Malia are attacked by a berserker, they all attack the berseker, working together as a real wolf pack would in order to take down a bigger prey. They eventually gain the upper hand, he and Peter hold the berserker back as Malia goes in for the killing blow with the bone dagger but Kira stops them and informs all of them that the berserker is Scott. Liam realizes that this is the truth when he looks into its eyes, but that heitattion is what led Scott to break free and choke Liam up against a wall, Liam pleads with Scott to stop, he says "you’re not a monster. You’re a werewolf, like me."

This registers to Scott and he regains control. Scott rips of the berserker clothing and accuses Peter of helping Kate Argent, then he watched as Scott and Peter fought. Scott is receiving the worst of the fight, Liam steps forward as if he is going to jump in so Peter throws an old church chair at him, this triggers something in Scott and he comes to the defense of his Beta.

Later Hayden explains their plan to attach a lightning rod to funnel a rider into the tunnel where they plan to grab him and push him into the Argent bunker. Once the door is closed there’s no way for him to ride the lightning back out. Douglas questions how they can keep him from riding the lightning right out of the tunnel before they get the door closed. Liam suggests their lightning rod would redirect the bolt meaning the rider could grab it. The teacher says they should assume the Riders have some sort of way to direct and control the lightning strikes. Douglas says they need to absorb a lightning bolt but he can’t build a conduit that could absorb even half the energy. The bell rings and Liam and Hayden head out to class. Liam suggests they could find a person to absorb the lightning. Hayden says she doubts even Kira could do that. Liam says Josh could do it because he ate electricity. She reminds him that Josh is dead but Liam points out that his power is not. Hayden says it might as well be dead because they can’t get to it. While they never come right out and say it, they discuss trying to bring Theo back from wherever he ended up at the end of Season 5. Liam says he knows it’s insane but he needs Hayden to back him. Later in the tunnels, Hayden points out that there is still time to bail on the plan to retrieve Theo. Liam admits it’s not the perfect plan but they need “the bad part of the plan to make the good part work.” They’re met in the tunnels by Noshiko Yukimura who has her daughter’s sword. She too believes it’s a bad plan. She gives them one more chance to change their minds but they refuse. Liam says they don’t know what else to do because the Ghost Riders seem unstoppable. Noshiko says they are unstoppable. She explains that they’ve been riding the storm and taking souls since long before she was born. Liam pleads, saying they won’t survive them without her help. Noshiko says Kira entrusted her with the sword while she is off with the Skinwalkers. She says she’s now trusting Liam because Noshiko believes her daughter would want her to do so. She clarifies that her trust should not be mistaken for agreement with what Liam has planned. He says he understands. He explains that Kira sent Theo away by stabbing her sword into the ground. Noshiko says if he wants to do it, he’ll have to do it himself. She bows and hands him the sword. Noshiko says once it’s done, Liam is responsible for whatever happens. She then leaves the two teens alone in the tunnel. Liam moves to thrust the sword, at the last minute, Hayden yells for him to wait but it’s too late. The sword strikes the concrete. A large glowing crack jets forward from the sword. A few feet from where they’re standing, the ground explodes as a clawed hand shoots into the air. Theo climbs out of the hole and growls at them. Theo pushes Liam against the wall. Hayden pleads with him saying they brought him back. Theo asks about his sister. They explain that he killed her. He says he’s going to kill them all and shoves Liam again. Hayden says to send him back. Liam explains what Kira’s sword can do and Theo backs off. Liam says they need his power and then he can kill whoever he wants but that if he does kill them, he’ll be worse off than ever. Theo says there’s nothing worse than what he’s been through. Liam explains about the Ghost riders. Elsewhere in the tunnel, Mr. Douglas has rigged up a wire and a gadget to simulate the high voltage of a lightning bolt. They have Theo grab the wire and turn up the juice. Theo is knocked backwards. Douglas explains that Theo was knocked down by “only a billion joules” and that a lightning bolt is five times as strong. They realize he no longer has Josh’s abilities. Hayden checks his claws and realizes he doesn’t have Tracy’s Kanima abilities either. Theo quips that he’s back to “classic Theo.” Liam is angered and says he should be remorseful since Theo killed his pack members for those powers. Theo says he just put them back the way he found them. Hayden says they should send him back and Liam moves to do it. Theo tries to talk them out of it saying he knows about the Wild Hunt from the Dread Doctors. He also hints that he knows the truth about Garrett Douglas but doesn’t come right out and say that he was the Doctors’ Nazi Werewolf in a tube. Despite Theo’s discretion, Douglas says Liam should send him back down below. Theo asks who’s making these decisions and wants to know where Scott and Stiles are. Realizing that Theo remembers Stiles convinces them to keep him above ground. Later at Scott’s house, Theo explains that they can’t get Stiles back. He says the Wild Hunt comes and the Wild Hunt goes. Liam says they’re not going, they’re staying in Beacon Hills and still taking people. Theo says that’s not possible. He says they won’t just stick around unless they’re stuck. Liam says Theo is going to help them but Theo says he doesn’t know what to do. Hayden says he remembers Stiles so he clearly knows more than they do. Liam threatens him with the sword again. Theo realizes Scott wasn’t part of the plan to bring him back.

Personality

When Liam was first introduced, he appeared to be outgoing and overconfident teenage boy, but it was quickly revealed that his character was much more complicated and nuanced than he appeared at first glance. After the initial shock of his transformation into a werewolf, Liam demonstrated that he is also a very supportive and loyal friend to those who he truly cares about, such as his best friend Mason, his girlfriend Hayden, his Alpha and good friend Scott, and the rest of his pack. He's also shown that he is incredibly brave and quite intelligent despite being considered to be more brawny than brainy.

However, despite all of these good personality traits, he does have a few bad ones, mainly his difficulty controlling his anger. Liam was diagnosed with intermittent explosive disorder as a freshman, which causes him to be incredibly impulsive (which can lead to irrationality and poor judgment), as well as possessing a quick temper that causes him to be eager for a fight when angered. Though his transformation into a werewolf amplified this to an extent, as lycanthropy can cause anger issues in those who have been transformed by the Bite or a scratch, Liam's inclusion in the McCall Pack and the good influence of his close friends has helped him get better at controlling his temper and staying in control in both his human and werewolf sides. Despite this general improvement in Liam's anger and personality in general, he is still prone to bouts of irrationality and violence in certain circumstances, such as the most recent supermoon, when the affect of the moonrise combined with his anger toward Scott and fear of Hayden's impending death made it easy for Theo to manipulate him into killing Scott to the point that he actually believed that he wanted to do so at the time. Afterward, however, Liam was so horrified by his behavior that he has dedicated himself to making up for it, and has demonstrated a much better sense of control over his emotions ever since, due in part to his reconciled relationship with Scott and his romantic relationship with Hayden.

Physical Appearance

Liam is a short-statured young man with an athletic and lean build. Due to his intense work-out schedule, both out of love for lacrosse and an eagerness to help control his anger, Liam is quite muscular for his age, and he has honey-blond hair, tanned white skin, and blue eyes. He prefers comfortable clothing such as hoodies, baseball shirts, jeans, and sneakers, though he has shown to wear more trendy clothing like leather jackets and boots when going to Sinema with Mason.

Powers and Abilities

Powers

Liam possesses the standard powers of a Beta werewolf, though he is considered to be exceptionally powerful for his age and rank as a result of his anger, which boosts his strength considerably. Additionally, as he is Scott's first bitten Beta, Liam is one of only two people who can steal or inherit Scott's Alpha spark, the other being Hayden.

Abilities

Aside from his werewolf powers, Liam possesses several abilities that have helped him throughout his time on the series. For example, even prior to his transformation into a werewolf, Liam was exceptionally athletic, to the point where Scott and Stiles suspected him of being a shapeshifter despite being only a human at the time. Coach Finstock has referred to Liam as the most talented lacrosse prodigy he has ever coached in his career, and his lacrosse skills have only improved with the addition of his werewolf powers.

Liam has also been shown to have an excellent memory, with the ability to recall conversations and even small details when it is important. For example, he was able to remember the conversation he had with Scott McCall during his first full moon about his anger and recalled how he explained to Scott what his step-father told him about how angry kids acted in order to help himself attempt to escape from the well where Garrett trapped him. He also remembered the leaf pendant necklace he found in the hole he fell into in the Beacon Hills Preserve and was able to identify it as belonging to Tracy Stewart after seeing a photo of her wearing it, an important observation that helped the McCall Pack learn that being buried alive in the woods was part of the Chimera transformation process.

Though he doesn't seem to have formal training, Liam has shown that he is a great fighter by combining his werewolf powers with his instincts, particularly when angered or afraid. His style of combat is more similar to the brawling style also utilized by his packmate Stiles Stilinski. During the supermoon, while empowered by its power and his own rage, Liam was able to overpower and almost kill Scott.

Weaknesses

Liam possess all the standard weaknesses associated with werewolves, including wolfsbane, mountain ash, electricity, ultrasonic and subsonic frequencies, full moons/supermoons, lunar eclipses, and heightened emotions.

Etymology

Liam: Liam is a short form of the Irish name William, a derivation of the Frankish name Willahelm. The name breaks down into two Old German elements-- vila ("will," "desire," "resolution") and helma ("helmet of will," "guardian"). In Arabic, the pronunciation equivalent to Liam means "harmonious in opinion or feeling," while in Persian, the name is of a plant in southern Iran whose name means "protector and supporter," a fitting title, considering that as a member of the McCall Pack, Liam Dunbar is both a protector and a supporter. In Hebrew, Liam can be translated into "my nation" or "my people." Because of the Norman conquests, Saxon names were replaced by an influx of French names that were quickly adopted by the English, Welsh, and Irish in the region. Related names are William, Wilhelm, Will, Bill, Gwilym, and Guillermo.
Dunbar: Dunbar is a Scottish habitational name from Dunbar, located on the North Sea coast near Edinburgh. It is a combination of the Gaelic words dùn, meaning "fort," and barr, meaning "top" or "summit." It can also mean "castle headland" due to the fact that the town of Dunbar is at the mouth of the Frith of Forth in Scotland, so named for the fact that it is situated on a rock that overlooks the sea. It is also the name of a Scottish clan hailing from the Lowlands of Scotland.
