Mason after learning about the supernatural

Mason is a supporting character in the fourth, fifth, and sixth seasons of Teen Wolf. He is a sophomore at Beacon Hills High School and the best friend of Liam Dunbar. Despite being new to the supernatural, having not truly learned about its existence until early in Season 5, Mason does everything he can to help his friend and the McCall Pack, even at his own risk. He has become their loyal ally, and has assisted them in numerous ways, including by helping Liam reconnect the Chimeras Hayden Romero and Corey with their humanity following their resurrections at Theo Raeken's hands. He had even helped the pack considerably prior to knowing about the supernatural, such as when he stopped the subsonic frequency-laced music during the lacrosse bonfire, which allowed Scott, Liam, and Malia from being killed by the Deadpool assassins masquerading as security guards.

In Maid of Gévaudan, it was implied that Mason is actually the Dread Doctors' only successful Chimera, who they made the vessel for the newly-resurrected Beast of Gevaudan, previously known as Sebastien Valet. This was subsequently confirmed in The Beast of Beacon Hills, when Sebastien finally remembered who he was and transformed Mason's body into his own. Fortunately, the McCall Pack never gave up hope that part of Mason still lived on in Sebastien, and Lydia Martin was able to give Mason his body back by using her Banshee voice to call out his name. With the Beast finally defeated, Mason has returned to his usual self, though the full extent of the psychological turmoil Mason may or may not be experiencing as a result of everything Mason did while the Beast remains to be seen as of now.

Early Life Edit

Not much is known about Mason's life pre-series, as he has yet to mention much about his parents or whether he has any siblings. However, he has dropped several hints that suggest he is from a wealthy family, such as when he paid $200 for a rare bestiary from a German book dealer ("Parasomnia"), when he was able to get himself and Liam into Sinema by bribing Hayden with $50 ("Condition Terminal"), and when he remarked that his parents had bought him a brand new car for his birthday. ("Lie Ability")

What is known is that he and Liam Dunbar have been best friends since at least the sixth grade, and he has been a friend of Hayden Romero since at least that time as well, suggesting that Mason has lived in Beacon Hills for most, if not all, of his life. ("Required Reading")

Throughout Teen Wolf Edit

In The Benefactor, Mason, Violet and Garrett departed from the school bus and head toward school. When Garrett remarked that he didn't want to be home watching movies on yet another Friday night, Mason pointed out that they're freshmen and they just got off the school bus, which meant they won't be "hitting the clubs 'til 4AM." Moments after Violet insisted that they would be having a movie night at her house at 9PM before she and Garrett went inside, Liam arrived out front, looking pale and sweaty. Mason looked concerned and asked him why he wasn't on the bus with them, but Liam, who, unbeknownst to Mason, was in the middle of completing his transition from human to werewolf after being bitten by Scott McCall, lied and said that he ran to school. Mason didn't seem to buy Liam's story, since Liam lives three miles away from school, and he only became more concerned when Liam began to sway weakly on his feet. However, he didn't push Liam on the issue, and later had class with him.

After school, Liam had been tricked by Kira Yukimura into coming to a "party" at Lydia Martin's family's lake house, not knowing that, in reality, the McCall Pack intended to give him a supernatural intervention before that night's full moon. Mason texted Liam while he and Kira were on their way to the lake house to ask him where he was, and Liam, not yet realizing that it wasn't actually a party he was about to attend, invited Mason to the lake house as well. Mason, in turn, invited Garrett and Violet, which ultimately led to at least fifty freshman showing up at the lake house for a party that wasn't actually planned to occur. Just as the moon hit its peak, Scott and Kira took Liam into the boat house while Stiles and Malia went to the basement, leaving Lydia alone to host the impromptu party.

Mason, Garrett, and Violet led the large crowd to the door, which Lydia answered. When Mason asked if they were in the right place for the party, Lydia replied, "Absolutely" and ushered them in. Mason immediately began looking around for Liam, even going upstairs despite Lydia's orders for everyone to stay downstairs. Lydia followed him into the upstairs study and instructed him to go back to the party, but Mason insisted he was just trying to find Liam. Lydia, getting overwhelmed and frustrated with having to cover for her supernatural friends, retorted that "missing freshmen" were low on her priority list, which led Mason to point out that she clearly cared enough to know he was a freshman. Rolling her eyes, Lydia lied and said she might have seen him downstairs while she picked up two abandoned wine glasses, but as she tried to usher Mason out of the room, she accidentally spilled the wine on the pristine white carpet of the study.

Lydia began to cry as she frantically tried to mop up the wine with her sweater, and Mason looked extremely guilty as he apologized for what happened. When he asked her if the carpet was valuable, Lydia confessed that the problem was that nothing in the lake house was valuable, and that she needed to keep it perfect because she and her mother were selling it and needed to get every penny they could out of it. Mason, feeling even worse now, comforted Lydia, assuring her that he would go get club soda and salt to get the stain out, and that it would all be okay.

In I.E.D., he and Liam were in the weight room working out, with Liam using the bench press and Mason doing bicep curls with hand weights. While they exercised, Mason mentioned that Garrett had borrowed his hoodie and never returned it before stating that he went to the new housing development on Spaulding where Garrett he lived. When Liam didn't understand Mason's point, Mason revealed that the housing development was "still in development," and that unless Garrett was living in a backhoe, he had lied about where he lived.

Mason then used this story to segue into his concerns about Liam, bringing up the fact that his best friend was doing uncharacteristically strange things like running three miles to school and disappearing at parties. It was then that Mason realized that Liam had nervously added nearly 400lbs to the bench press' barbell and wondered aloud if Liam was on steroids before asking him if he really intended to lift it. Liam, alarmed by the fact that Mason was getting suspicious about his new supernatural traits, immediately stopped what he was doing, and was slightly relieved when Mason mistakenly attributed Liam's strange behavior to the upcoming lacrosse game. Liam explained that he wasn't worried about it, since it was only a scrimmage, but when Mason reminded him that they were playing Liam's old school, Devenford Prep, Liam became anxious.

After school, Liam and Mason approached the Devenford Prep bus as they pulled up to Beacon Hills High School. When Liam's former rival Brett Talbot and his friends departed the bus, Mason became nervous as the Devenford players came off the bus and immediately began taunting Liam for his behavior toward their coach, which is what got him kicked out of school. Mason became even more concerned when he saw Scott and Stiles show up and usher Liam into the locker room before things could get violent. At the scrimmage, Mason was on the sidelines with Liam just before the match started, and when Brett began changing into his uniform on the other side of the field, Mason couldn't help but check him out. When Liam realized what he was doing, he called Mason out on finding Brett attractive before pointing out that Brett wanted to destroy him. Mason attempted to deny his attraction to Brett before eventually retorting, "I think you could definitely take him... And then give him to me."

Afterward, Mason joined Violet in the bleachers and watched the game with her, helping her hold up signs for Liam and Garrett. He was horrified when he saw a very bad tackle between Brett Talbot, Garrett, and Liam, the former of whom was, unbeknownst to Mason, cut with a wolfsbane-laced blade hidden inside Garrett's lacrosse stick.

In Orphaned, Mason and Liam went on a run through the Beacon Hills Preserve behind the high school, where both boys were clearly rattled by the events of the previous night, albeit for different reasons. Mason nervously rambled to Liam about the fact that it had been revealed that Violet and Garrett were actually professional assassins who were only befriending them as part of their cover. Liam, who was concerned about the Deadpool in general but couldn't tell Mason this, remained quiet and focused on the run, and when Mason demanded to know how he wasn't more freaked out about this revelation about their so-called friends, Liam insisted that he was worried about a lot of things before taking off on a dead sprint. Thanks to Liam's new super-speed due to his werewolf transformation, Mason couldn't keep up with him, and though Mason shouts at him to wait for him, Liam kept going.

Before Mason was able to catch up with Liam, Liam was hit by Garrett's SUV and stabbed with his wolfsbane-laced blade before he was captured. Mason stopped right around where Liam had been nabbed and looked around, but couldn't find him anywhere, not noticing the small puddle of blood near his feet. After realizing that Liam was gone, Mason returned to the high school and sought out Scott McCall to see if he had seen Liam, since he had noticed the two had struck up a friendship. When Scott revealed that he hadn't seen Liam either, the two went to talk to Coach Finstock, who was in the middle of chugging a bottle of cold medicine and who informed them that Liam had skipped his class. When Coach suggested that perhaps Liam was sick as well, Mason told Scott that he hadn't looked sick on their run. Just then, the late bell rang, which led Scott and Mason to agree to let the other know if either of them ended up finding Liam before they went their separate ways.

In Perishable, Mason caught up to a visibly-panicked Liam (who had been experiencing post-traumatic flashbacks to his battle with a Berserker several days earlier) at school. Mason asked Liam if he planned to go to the bonfire that night, and when Liam admitted that he was probably going to skip it, Mason reminded him that he couldn't skip because attendance was mandatory for members of the lacrosse team. Mason continued to encourage Liam to go to the bonfire by outlining his plan for them; namely, he wanted to help Liam find a "nice girl he can embarrass himself in front of" and then find Mason a hot lacrosse players, since, in Mason's words, "Statistically speaking, someone on your team has gotta be on my team, right?" Liam, on the verge of another flashback-induced panic attack, quickly agreed to go to the bonfire with Mason before he left for class.

That evening, Mason and Liam sat together at an outdoor picnic table during the bonfire, where Mason watched Liam fill up his soda bottle with a bottle of vodka hidden in a brown paper bag. Though he's somewhat concerned by how heavily Liam seemed to be drinking, Mason insisted that he wasn't going to warn Liam to slow down; on the contrary, Mason insisted that he wanted him to get "blackout, head in the toilet" drunk so that maybe then, Liam would be more inclined to tell him the truth what has been going on with him lately instead of continuing to lie. When Liam started to clam up, Mason insisted that he wasn't asking simply because he wanted to know, but because he wanted to help, and though Liam seemed to appreciate Mason's concern, he assured him he was fine and left to get more alcohol.

Later on, Mason became even more worried when Liam began acting much more drunkenly than he should have been based on how much alcohol he had drank, and he eventually met up with Scott and Malia, the latter of whom was experiencing the same symptoms despite only having a few sips of vodka from a flask. When Scott asked Mason how much Liam had to drink, Mason insisted that he didn't drink enough to be barely-conscious and stumbling around like he was, and Scott became very concerned about what was happening. However, when he started to tell Mason that they all needed to go, Scott began slurring his words, leading Mason to ask how much alcohol Scott himself had drank. When Scott assured him that he hadn't had a sip (which was true, since, as a werewolf, Scott can't get drunk anyway), they both became even more worried about what was going on. After a moment, Scott realized that somehow, the subsonic frequencies in the music the DJ was playing was affecting him, Liam, and Malia due to their werecreature-enhanced hearing. Unable to tell this to Mason, Scott simply told him that he needed to turn off the music and ordered Mason to not let Liam and Malia out of his sight.

Unfortunately, shortly after Scott left to head to the DJ booth to shut off the music, the DJ turned up the volume, sending Scott to his knees and weakening him enough to allow the security guards to capture him. Afterward, the other guards went after Liam and Malia, and when Mason insisted that they were his friends and was taking care of them, the guard claimed that Liam and Malia were overly intoxicated and needed to leave. Mason offered to go with them, but the security guard, having ulterior motives, shoved Mason onto the ground before dragging Liam and Malia into the high school where the others had brought Scott. Remembering Scott's words about the music affecting the three, Mason walked over to the DJ booth and found the cord that hooked up to the speakers before yanking it out of the plug. Though Mason was unaware of just what he had done, he had inadvertently saved the lives of Scott, Liam, and Malia, as the security guards had doused them in gasoline and was about to set them on fire when the music was cut off, allowing Scott to steal the lighter away from the guard in time for Braeden and Derek Hale to take out the guards.

In A Promise to the Dead, Mason was playing games in Liam' bedroom, where Liam seemed to be dominating him. Mason wondered aloud how Liam became so good so quickly, and asked him if it was because he had been practicing or because he had somehow developed superhuman reflexes. Liam nervously insisted that he had just been practicing, not wanting Mason to find out that he is a werewolf, and Mason seemed to accept this answer before standing to his feet and preparing to leave, citing the fact that they have a history test the next day. Liam, who was still having flashbacks and panic attacks to his battle with the Berserker, pleaded with Mason to stay for one more game, but Mason reminded him that he had already been talked into "one more game" four times and that he really needed to study. Not wanting to be left alone, Liam instead suggested that they could study together there and that Mason could stay the night, which led Mason to sense that something was wrong with Liam. However, when Mason asked Liam once again if he was okay, Liam began to clam up and insisted that he was fine before reluctantly stating that he would see him the next day. Mason seemed to not believe Liam's insistence that he was fine, but he ultimately left to go home anyway.

The next day, Mason and Liam went to the weight room as usual, where Liam, who had been up all night having flashbacks about the Berserker, seemed tired and irritable. When Mason noticed just how much weight that Liam was putting on the bench-press bar, he offered to spot Liam, but Liam somewhat rudely declined and instead asked Mason, who was only holding eight-pound handbells in each hand, if he needed a spot, leading Mason to retort, "This is my warm-up, dick." When Liam prepared to start bench-pressing, Mason walked around the bench and prepared to spot Liam anyway, claiming he didn't want to see Liam kill himself with too much weight. Now very annoyed, Liam did two reps in front of Mason before snidely asking him if it looked like he needed help. Realizing that something was clearly up with Liam, Mason backed off and went across the room to work out by himself, leaving Liam alone on the bench-press. Though his first few reps went as planned, he eventually had a panic attack caused by flashbacks of the Berserker battle, which temporarily blocked his super-strength and prevented him from lifting the weight from his chest.

Mason didn't notice Liam's struggle until Scott, who had sensed something was wrong with Liam through his werewolf senses, rushed into the weight room and pulled the bar off of his chest, allowing Liam to sit up and pant for breath. Mason watched in horror at the fact that Liam had nearly hurt himself badly, and was confused when he overheard Scott whisper, "If you don't want to be with us, that's okay. But don't push your friends away, too." That evening, Mason showed up in Liam's room with a stack of video games and stated that he knew something was going on with Liam, and that he's well aware that he doesn't want to talk about it. He went on to say that Liam was his best friend, and that since the last friend ended up being a professional killer, he didn't have many option for new ones. Mason then added that he planned to wait until Liam was ready to tell him what was going on, and that until then, there had to be a video game in that stack in which Mason could "kick Liam's ass." Liam laughed and chose a game he hadn't yet played before the two began to play.

The next day, Mason attended the lacrosse game with Sydney, once again holding up signs cheering on Liam, who was clearly struggling with his panic attacks and the upcoming full moon, though he was eventually helped by Brett Talbot.

In Smoke and Mirrors, Mason was at a study group at the school when Liam (who was about to leave for Mexico to rescue Scott and Kira from Kate Argent) called Mason to ask him to look for Lydia Martin, who was also at the high school and who wasn't replying to their phone calls. Mason, still on the phone with Liam, saw that Lydia's car was still in the parking lot of the school and agreed to call him back as soon as he found her.

When Mason went back inside the school, he looked around several of the empty classrooms before finding Lydia's phone and the jacket Lydia had retrieved from Kira's jacket laying on the staircase. He muttered to himself that this must be why Lydia wasn't answering Liam and the others' calls and texts before picking up the phone to find a blurry photo of a Berserker had been set as the lock screen as a warning/clue from Lydia. Before Mason could wonder what was going on, the Berserker appeared and backhanded Mason so hard that he was knocked unconscious before he was dragged downstairs to the basement where Lydia was also being held hostage.

Mason awoke in the basement with a bleeding wound on his temple and a bad headache to find Lydia kneeling next to him to check on him. Mason was horrified to find that the Berserker had taken his phone, but Lydia stated that this was the point, since it clearly didn't want them to call for help. Mason, who still knew nothing about the supernatural, began describing the creature as "a man with a bear skull over its face," but when he demanded to know what it was, Lydia simply replied that it wasn't human. Lydia, who knew that the pack was on their way to Mexico to save Scott and Kira, wanted to make a break for it and asked Mason to check and see if the Berserker was still guarding the hall, which Mason confirmed that it was.

When Lydia, desperate to save her friends, found a container of baseball bats and decided to go after the Berserker, Mason asked her if she was crazy, leading Lydia to explain that her friends were in danger, as was Mason's best friend Liam. This seemed to shock Mason into action, and before Lydia could rush after the Berserker, Mason had grabbed a baseball bat of his own and lunged for the Berserker with a battle cry. Mason only got in several hits before the Berserker threw him backward, hitting the wall at the other end of the hall, and Lydia was only able to hit it several times as well before she was thrown backward and landed in a heap next to Mason. When the Berserker stormed toward them, Mason brought up the fact that Lydia had said that it didn't want to hurt them, it just wanted to keep them from leaving, Lydia shrieked that it seemed to have changed its mind.

Fortunately for them, Sheriff Stilinski arrived just then and called out, "Excuse me!" causing the Berserker to briefly forget about Lydia and Mason as he turned toward the Sheriff. Sheriff Stilinski then tossed The Mute's unused claymore mine at the Berserker, who caught it and looked at it just as Sheriff dove into the adjacent hall, waiting until Lydia and Mason quickly took cover behind a bookshelf before pushing the button on the remote detonator. Once the dust settled, Mason, Lydia, and the Sheriff climbed out of their hiding spots and gathered in the hall, where they found that the Berserker had been turned into a pile of dust with a bear skull on top. Lydia revealed that she believed this was all some kind of distraction in order to prevent her from catching up with the others, and Mason looked alarmed and confused when Sheriff seemed to know exactly what she meant. When Sheriff guessed that it was because Lydia knew someone was going to die, Lydia nodded grimly in confirmation. Mason, even more alarmed now, asked her who was going to die, and Lydia was near-tears when she replied, "Scott."

In Parasomnia, Mason and Liam were walking down the hallway at school toward Ken Yukimura's history class, where Mason pulled out an old-looking book to show Liam. He explained that he found it online at a rare German bookstore, and claimed that it was totally worth the $200 he paid for it. When Mason showed him a diagram inside of what appeared to be a Berserker, Liam realized that it was essentially a Bestiary and asked him if he was really still researching this stuff. Mason reminded him that he had been captured by an "armor-plated giant wearing a bear skull" and that it left an impression. As they approached the classroom, Mason showed Liam a section in the book about the Nahual and was about to ask him if he had heard of a certain Aztec god, but was unable to pronounce the name, leading Liam to look at the page and correct him on the pronunciation of "Tezcatlipoca" before lying and claiming he'd never heard of him.

Inside the classroom, Mason took his seat near the front, and Liam was about to sit down in the desk next to him when he realized that his then-frenemy, Hayden Romero, was seated on his other side. Liam looked around the room for somewhere else to sit, but when he found there were no other open seats, Mason began to laugh at Liam's misfortune as he watched him stand awkwardly in the aisle. Mason only became more amused when, after Ken ordered Liam to sit down, Liam found that Hayden had stuck her gum on his seat, which was now all over his jeans. After class, Mason continued his earlier conversation with Liam by stating that while he didn't 100% believe in the supernatural, he was certain that people around them knew things, especially Lydia. Liam, still scared of telling Mason the truth about the supernatural out of fear of him being rejected as well as fear of Mason being hurt, tried to distract Mason by pointing out that the soccer team was about to practice shirtless on the field, which worked well enough to get Mason to go out onto the field to watch them and pretend to study while they practiced.

That night, Mason and Liam had planned to work out together at the school, but Liam, who had been helping Stiles investigate Theo Raeken, who had recently returned to Beacon Hills after moving away eight years earlier, forgot until the last moment. While Liam was with Stiles, he admitted that he had yet to tell Mason that he was a werewolf and that the supernatural existed, and when Stiles reminded him that he and Scott had given Liam permission to tell Mason the truth, Liam worried that Mason wouldn't believe him, or would be scared of him. Stiles insisted that since Mason had seen his father blow up a Berserker with a claymore mine, which had "thoroughly laid the foundation for acceptance," Liam worried aloud that Mason would hate him or try to stab him with silver.

Later, Liam rushed to the high school to meet up with Mason, who angrily pointed out that he was two hours late and that he had already worked out without him, Liam sighed and informed him that he was going to explain everything to him, though he warned him that what he was about to tell him would be hard to believe. However, before Liam could confess the truth to Mason, Mason became alarmed at the sight of a wolf behind Liam, and when Liam turned and saw the wolf growling at them, Liam and Mason ran into the school to try to get away from it. Realizing that he needed to protect Mason by scaring the wolf (who would later be revealed to be a fully-shifted Theo) away, he waited until Mason had run up the steps before flicking out his claws, fangs, and glowing gold eyes and roaring so powerfully that the wolf scampered away. Mason turned around just to see Liam's fangs and claws receding, and when Liam grimly stated that he had something to tell him, Mason smiled in excitement and exclaimed, "You're a werewolf!"

Personality Edit

During his time on the series, Mason has proven himself to be a brave, intelligent, curious, resourceful, and loyal person. He is one of the few openly gay students at Beacon Hills High School, which demonstrates a great amount of courage; this courage was evidenced again when he managed to save the lives of Scott McCall, Liam Dunbar, and Malia Tate before they could be killed by amateur assassins during the Deadpool, even despite the fact that he didn't know about the supernatural and was simply going off of what he heard Scott say about the music.

Mason's personality is somewhat similar to Stiles' in that he is intelligent and curious to a fault, to the point that he can't help but research the supernatural in hopes of learning something that can help his friends. He has also demonstrated an immense sense of loyalty and kindness, especially to his best friend Liam, who he supported without judgment when he knew that Liam was hiding something (his lycanthropy) from him; Mason was even able to snap Liam out of his supermoon-enhanced rage to stop him from killing Scott, suggesting that Mason may even act as a sort of anchor for Liam's Werewolf side.

In short, Mason is an extremely good person who typically gets involved in the supernatural drama in Beacon Hills due to his willingness to help whenever and wherever he can. After his first encounter with the supernatural, during which time he and Lydia Martin were attacked by one of Kate Argent's Berserkers at the high school, Mason became fascinated by the mystical world within Beacon Hills and dedicated himself to learning more, even spending hundreds of dollars of books on Tezcatlipoca, the Nagual, Berserkers and other creatures. This research was aided by his highly observant nature, which allowed him to realize that Lydia definitely knew more than she was letting on, as did Liam. Once Liam revealed the fact that he was a werewolf, Mason was excited rather than afraid and only became more eager to join the McCall Pack and help them protect the town.

Physical Appearance Edit

Mason is of average height, 5'8", with a slim, lean build. He has medium-brown skin with dark brown eyes and short black hair, and typically leans toward trendy, comfortable clothing, such as button up shirts in bold colors and patterns with slim-cut dark jeans and sneakers or boots, often paired with a leather or khaki jacket. He has his ears pierced and typically wears white stone studs in them, though this seems to be the extent of the jewelry he wears.

Powers and Abilities Edit

Former Powers

As a genetic chimera, Mason had the qualities the Dread Doctors desired in their test subjects to become supernatural Chimeras, with the ultimate goal of finding a suitable vessel for the spirit of the resurrected Sebastien Valet, also known as the Beast of Gevaudan. During his possession, Mason possessed the following powers, though it is believed that he no longer has supernatural powers due to Sebastien's spirit being killed by Scott McCall. These powers only seemed to be active while in Beast form at night, as Mason seemed unaware that he had powers while he was a human during the day.

  • Super Strength: As the Beast, Mason possessed supernatural strength to such a high degree that he was physically superior to even Alpha werewolves and Hellhounds, who are known to have the greatest level of physical strength among shapeshifters. Mason was able to bend thick metal doors with his bare hands, break through solid walls, and throw humans and supernatural creatures alike around like rag dolls. This was especially evident when Mason literally ripped a teenage boy in half using only his clawed hands. He was even able to crack the ground beneath him by simply pounding both of his fists against the earth, which created a large fissure.
  • Super Speed: As the Beast, Mason possessed extremely heightened supernatural speed, which was made even faster by the fact that in his Beast form, Mason was roughly nine feet tall and had very long legs that allowed him to take large strides. He was so fast that even the Hellhound Jordan Parrish struggled to keep up with him, as he moved so quickly he appeared to be a blur.
  • Super Agility/Reflexes: As the Beast, Mason possessed supernaturally-enhanced agility and reflexes even despite his large mass in Demon Wolf form, allowing him to easily dodge strikes and projectiles with ease.
  • Super Durability: As the Beast, Mason possessed such supernaturally-enhanced durability that neither extreme blunt force nor projectiles such as arrows or bullets seemed to cause him much, if any, damage, putting his durability at a level similar to Berserkers.
  • Super Senses: As the Beast, Mason possessed supernaturally-enhanced senses of sight, smell, and hearing, allowing him to see in the dark and across long distances, track scents for up to several miles and interpret the chemosignals in scents that indicate identity and emotional state, and hear at such a heightened level that he could hear whispered conversations from several meters away. His Beast eyes also presumably allowed him to see supernatural phenomena that aren't typically visible to human eyes, such as a Kitsune's aura or the Nemeton while it is trying to shield itself.
  • Accelerated Healing: Though Mason, as the Beast, possessed immense supernatural durability that made him resistant to many forms of harm, his body was also capable of healing itself at an accelerated rate in the rare cases that he was injured. This may have also extended to giving him a perfect immune system and an extended lifespan, had he retained his powers.
  • Shapeshifting: As the Beast, Mason possessed a highly advanced form of shapeshifting that made him unique among werewolves. Like normal werewolves, he had the ability to partially shapeshift his features into that of a wolf, such as glowing blue eyes and viciously sharp fangs and claws. However, shapeshifting into his full Beast form involved summoning the shadows around him and wrapping them around himself, making the shadows solid and allowing him to increase his height and mass to an extremely high degree. Once he was fully transformed, Mason was a nine-foot-tall and immensely muscular bipedal Beast who was as black as oil and who had visible orange-red veins tracing the surface of his new skin. His claws also transformed into talons with a second set of shorter talons extending from his knuckles, and all of his teeth turned into sharp fangs instead of just his canine teeth.


In addition to his former supernatural powers, Mason has many human abilities that he has used to great effect to protect himself and defend his friends. He is a highly intelligent young man who is very skilled at research, allowing him to gain a wide knowledge base in everything from mythology and folklore to science. He is also an extremely observant person who suspected something was wrong with Liam Dunbar almost immediately after he was given the Bite by Scott McCall, which gives him the ability to utilize his problem-solving skills at a rapid speed.

Weaknesses Edit

Now that Mason is no longer the vessel for the Beast of Gevaudan, he presumably has been reverted to a human state (albeit one with genetic chimerism), giving him all of the weaknesses common to humans, such as mortality.

When Mason was the Beast, he was susceptible to certain high-pitched frequencies, which forced him to transform into his Beast form at the Dread Doctors' whims. This not only made him more physically powerful, but it also allowed Sebastien's spirit inside him to gain more and more control and memory of his identity until he was finally able to transform Mason into his original body.

Etymology Edit

  • Mason: Mason is a masculine given name that originated as an English occupational surname meaning "stoneworker," which itself was derived from an Old French word of Germanic origin masson, akin to the Old English macian, meaning "to make." Mason is also one of the earliest recorded surname due to its occupational origins, and first appeared as Macun in 1130. Another etymology of Mason could be derived from the given name Maso, the short form of the Italian name Tommaso (Thomas in English), which itself is derived from the Aramaic word toma, meaning "twin." This is an ironic twist, as Mason the character became a genetic chimera due to the fact that he absorbed his twin in utero, causing him to possess two sets of DNA.
  • Hewitt: Hewitt is an English, Irish, Welsh, and Scottish surname derived from the medieval given name Huet, a diminutive of Hugh. Hugh itself comes from the Germanic element hug, meaning "heart, mind, and spirit," a fitting name for a character who is known to possess all of these traits. In English, Hewitt is also a topographical surname given to someone who lived in a newly-made clearing in the woods, derived from the Middle English word hewett (from the Old English hiewet, a derivative of heawan, meaning "to chop, to hew").

Trivia Edit

  • Mason is one of several LGBT+ characters in the Teen Wolf series, including DannyEthanCaitlin, EmilyCorey, and Brett.
  • Mason wears size 10 shoes, as evidenced when Scott and Stiles found his bloody footprints at a crime scene after Mason had inadvertently transformed into the Beast and attacked Jordan Parrish.
  • Mason is a genetic chimera, though rather than becoming one due to an organ or tissue transplant like the other Chimeras, Mason became one because he absorbed his twin in the womb, in what is called fetal resorption syndrome.
  • Mason has been shown to have many similarities to Stiles Stilinski:
    • They are both (mostly) humans whose best friends (Scott for Stiles and Liam for Mason) are werewolves.
    • They are both incredibly smart and very good at problem-solving and researching, and have gone out of their way to learn as much as possible about the supernatural in order to help their friends.
    • They have both been possessed by the spirits of supernatural killers, who used their bodies to cause chaos, injury, and death to those around them; for Stiles, it was the Nogitsune, and for Mason, it was Sebastien Valet/the Beast of Gevaudan. Additionally, both will have to deal with the emotional/psychological aftermath of the deaths and destruction they caused during their possessions, even despite knowing that it wasn't truly their fault since they were not in control of their bodies at the time.
