"Know me? You've never seen anything like me. I am the alpha of alphas. I am the apex of apex predators. I am Death, Destroyer of Worlds! I - AM - THE DEMON WOLF!!" - Deucalion to Derek Hale.
"Become the alpha you're meant to be. Become a killer." - Deucalion to Scott McCall
"Pain. Life. Power. In that order and only that order." - Deucalion to Theo Raeken
The alpha werewolf known as Deucalion, prior to the series, was the lead alpha of his pack, allies with Talia Hale of the Hale pack, and Marin Morrell served as his emissary. He sought peace and a better future between hunters and the packs, but was betrayed, framed, and blinded by Gerard Argent. Eventually, he became corrupted, turning dark and ruthless, killing all of his pack to subsume all their power. Over the intervening years, Deucalion from then on sought only power above all else, forming a new pack comprised only of unique super-powered alphas for his new cause, including similarly augmented alphas Kali, Ennis, then later the twins, and earned himself the moniker The Demon Wolf. In Season 3, Deucalion is the leader of his elite Alpha Pack whom are present in Beacon Hills, California to undermine the supernatural town members, including intending to recruit local alpha Derek Hale. He actually plans to either eliminate or acquire Scott McCall, the most unique of canine werecreatures, a True Alpha. To this end, Deucalion employs his alphas to gain leverage on Scott's allies and orchestrates a subtle assault against Derek, while simultaneously manipulating them, betraying and killing Ennis. He and his pack then redirect their attention to the darach, Jennifer Blake whom is committing human sacrifices in a move against him. He finally draws Scott into fighting Jennifer with him as pack members. In the three-way struggle between Deucalion himself, the Darach, and Scott and Derek's allies, he is finally defeated, stripped of his pack and power, but gains his sight back due to Derek and Jennifer's actions. Deucalion witnesses Scott's rise to True Alpha, is reminded of humanity, aligning with Scott and saving the lives of the Darach's final sacrifices. He is spared by Scott and Derek on the condition he redeem himself. Deucalion honors his reprieve and reforms, paying the mercenary Braeden to rescue Derek from captivity by the Calaveras. In Season 5, Deucalion is tracked down, captured by the chimera Theo Raeken and his pack of chimeras amongst the terror and carnage caused by the Dread Doctors and the resurrected Beast of Gevaudan. He puts himself out as having resumed his ruthlessness and is blinded again, casting a vendetta against Scott. Theo wishes Deucalion teach him how to steal the beast werewolf's power, and in return he'll help him get back at Scott. He shows Theo the secret to steal the power from another. It is revealed that Deucalion had in truth sabotaged Theo and had disguised himself as being blind again; he was working with Scott all along to chip away Theo's hold over the chimeras and pay off his debt to Scott.
A victim of betrayal, loss, physical and emotional injury, and on top of everything, corruption, Deucalion changed, heading down a dark path.
As leader of the Alpha Pack, Deucalion is narcissistic, ruthless, obsessive and above all, power-hungry. He is proud and diabolical to the last detail. Deucalion is a charismatic leader, but also a manipulator skilled in planting then bringing out the darkness in people, i.e. shedding them of their humanity, turning them into killers. He has an eloquent cutting intelligence as he is a mastermind capable of orchestrating tactical plans of physical and emotional assaults against the most formidable of enemies to ensure his authority goes unchallenged. Deucalion will kill anyone in his way, even his own, to further his personal agenda.
After having his sight restored, thanks to Derek outwitting the Darach, and being spared by both Scott and Derek, Deucalion has reformed as he pays back both Derek and Scott back by hiring Braeden to rescue Derek from the Calavera hunters and sabotaging Theo Raeken respectively. He remains a masterful actor as he convinces Theo of his apparent returned dastardedness that he wishes to take Scott out, undermines Theo's hold over his pack and successfully convinces Theo that he's rendered helpless whilst being held hostage.
Powers and abilities
Deucalion speaks with a British accent. He wields a four-section cane that doubles as a dagger and a spear.
Deucalion, the lead alpha werewolf in a pack of alphas has exhibited the pinacle of a werewolf's power. His super-strength, speed, abilities and shapeshifting are unequaled. Though he's blind, Deucalion is actually able to see with his werewolf eyes. His defeat at the end of Season 3A and the loss of his pack severely broke his power, but his eyesight is restored by Jennifer Blake's magic.
Deucalion and a delegation of his pack, including a volatile beta Marco, arrived in Beacon Hills at the behest of a neighbouring alpha, Ennis, for aid against the Argent family of hunters. While prepared for the worst, Deucalion reasoned with Ennis for the Argents' killing his beta due to their motive that his wolf savaged and killed two of their people.
Deucalion proposed the idea, concept of peace with the hunters to the renowned alpha Talia Hale. He urgently pleaded Ennis not to send a message for vendetta, reasoning a war between the two powers will not end "at an eye for an eye", and in the end the packs will end up no better than their enemies. Ennis refused to listen, carving the spiral into the wall of an abandoned distillery, declaring revenge.
Deucalion, wishing to avoid further bloodshed, pushed further for his peace proposal, seeking out Talia and her emissary Alan Deaton's guidance before a meeting with Gerard Argent. Whilst Deaton admired his willingness to extend an olive branch, they both advised him against it, saying Gerard may not be the person to accept it, because of his bloodthirsty nature. They demanded however, he meet the hunters on equal grounds.
With Deaton's assistance, Deucalion's eyes healed, but his sight didn't return. The alpha was broken, enraged, demoralized at Gerard's monstrosity and his failure. At that moment, Marco, believing the blinded alpha wasn't fit to lead anymore, and hinted at being furious over their loss, told the older wolf he was alone, moved in to kill him and take over. Deucalion, partially shifting, realized he could still see with his werewolf vision. He reacted quickly, snarling, then viciously mauled and killed his treacherous beta.
Along the way, Deucalion went on to murder the rest of his pack, subsuming all of their powers. Deucalion then wished to assemble the "perfect pack", one which consisted of wolves only of alpha status, with himself as leader. Months later, he'd recruited fellow alphas Ennis and Kali to his new violent cause, assembling the Alpha Pack. In order to become one of his pack, they'd had to kill all of their previous pack to absorb their power, as well as their emissary. Overtime this new pack became the most feared and dominant from all around, and Deucalion, for his heinous legacy, came to be known as "the Demon Wolf"+++.
Later on, Deucalion came across a set of twins, Ethan and Aiden both of omega status staying with an infamous pack, all of whom were killers. He sought the the twins due to their ability to merge. He taught them how to control the talent, and after the two killed their way up the pack and killed their alpha both rising to alpha status, they joined Deucalion's pack out of repentance+.
Prior to the end Season 2, Deucalion's pack had arrived in Beacon Hills, were contacted overtime by Marin Morrell to serve as their Emissary, and having taken notice of Derek Hale's rise to alpha status. The lead alpha however, took notice of Scott McCall, becoming aware the young beta had the potential to be a True Alpha.
The Alpha Pack are all present at the hospital where Isaac Lahey, one of their hostages, has escaped to. Deucalion knows that Scott McCall has arrived. He follows the teenage werewolf into the elevator, using his cane to stall the door. He asks Scott to hit the button for the second floor, then if he would mind helping him around as a guide. Scott reluctantly complies with the man placing his hand over the teenaged beta.
The head alpha observes his prey with a serene smile. He unperturbedly walks over and kneels before the woman. He touches Braeden's face; he compliments her beauty, though he acknowledges her bravery. A bleeding, unflabbable Braeden talks back at the depraved wolf, saying she knows his fear of Scott's potential.
Deucalion: "I'm aware of a certain potential threat. But then someone once taught me a very smart way to eliminate a threat: get someone else to do it for you."
Deucalion: "Don't kid yourself, Marin. It's not the first time you've gotten your hands dirty."
The head alpha then takes his emissary's arm as she escorts him out of the bank.
The Alphas, minus the twins break into Derek's loft. After Ennis subdues Cora, and Kali impales and twists a pipe through Derek's mid-section. Deucalion takes a seat before the restrained, tortured Derek as if he's an old friend.
Deucalion: "So, let's chat."
Derek painfully demands Cora be let go. Deucalion motions at Ennis as a gesture of good will. Deucalion scolds Derek on the idea he's there to kill Derek, claiming he's not to be compared to his uncle, lecturing that he has far more "vision". He makes conversation, after Kali motions him to speed things along, stating a hazard with being in a Pack of only Alphas: "Everybody wants to make the decisions." Deucalion talks down to the dying Derek, saying his objective is being on the lookout for "new talent". Derek talks back, refusing, and that Deucalion wants him to kill his own Pack as he'd learnt from the trap last night. Deucalion corrects the lower Alpha he only wants Derek to kill one of his own. He explains that once he does, he won't even have to be asked to kill off the rest, because he'll do it on his own.
Deucalion launches a narcissistic speech explaining. He bring up the everyday rule of a Pack being strongest due to its members. He recalls a time when he'd killed a Beta of his own because he'd tried to usurp him as Alpha. Upon killing him, he learnt the Beta's power was added to his. The Alphas' leader lets Derek know he went on to kill off everyone else in his subordinate Pack as did Ennis and Kali.
Deucalion touches Derek's face. He remarks his resemblance to his mother. He tells Derek they'll get to know each other as he did with her. Derek, painfully, talks back telling the diabolical Alpha he's a fanatic. Deucalion announces to Derek that he's nothing Derek has ever seen with the following.
"I am the Alpha of Alphas.
I am the apex of apex predators.
I am DEATH, DESTROYER OF WORLDS.
I AM THE DEMON WOLF."
Having made their announcement and handed their proposition, Derek is freed, and Deucalion and his subordinates walk out of the loft.
Deucalion shows up at the high school where the twins have Merged in the high school, about to beat up Isaac and Scott. The leader silently walks up to them. The Merged werewolf is immediately submissive. He dissolves, separating back into Ethan and Aiden. Deucalion sharply slashes their faces with the concealed dagger in his cane for their breaking rank. They follow him out of the high school.
Scott is at the building housing the Argents' apartment after visiting Allison. He heads into the elevator, and as the doors close right then he sees Deucalion is also in the elevator with him. The lead Alpha jokes: "Going down?"
Scott then demands what does Deucalion want. He answers he "wants to see what (Scott) is made of." The elevator stops and people pile in while Scott quickly slips out. Deucalion asks for someone to hit the button for penthouse where he and his Pack are staying.
Scott tries to diffuse the situation between the two Packs: he arranges for only he and Deucalion to meet at an abandoned superstore.
Deucalion, however sarcastically asks Derek how would someone who's blind walk into a place as deserted as their location all alone.
The rest of the Alphas come out of their hiding places and converge upon everyone. Deucalion had broke the rules of his meeting with Scott as well.
The atmosphere is as tense as an elephant teetering on a trapeze wire. An obstinate Derek makes the offensive, targeting Deucalion, but Kali knocks him back. A full-on fight erupts between the two Packs while Deucalion, serene as ever, observes from the escalator. The super-charged Alphas make quick work of Derek's lesser Betas.
Arrows, flashbangs, suddenly rain down on all around the assembled werewolves. Deucalion orders his Alphas to cover their eyes. As both Packs recover, a standoff occurs between Scott and Ennis. Both Wolves ram into each other - Scott matches Ennis' charge with equal super-strength and afterwards he briefly sports the red eye color of an Alpha which Deucalion catches.
With Derek and Ennis falling off the edge of the floor to their apparent deaths two floors below, the battle ends with Packs dispersing.
Ennis is alive and has been brought to Alan Deaton's animal clinic for treatment.
Deucalion then lies to Kali and the twins, telling them that Ennis died from his injuries. His goal is now to enfore his Pack's own code: Derek has to join their Pack in repentance for Ennis' death or he must die+. To this end, he entices a vengeful Kali to push Derek into this corner.
In Beacon Hills high school, Deucalion is in the music room. By tapping his cane against the teacher's desk in a fixed rhythm, he discretely sends a message to Scott, luring him to the music room. He knows Deaton has been abducted by the Darach. He compares Scott's situation with a tempo being set, but a metronome is missing thus the rhythm is not steady. He offers to help Scott recover his "metronome" - helping Scott find Deaton. Scott's
Scott leaps at the Alpha taking him on. He tries multiple acrobatic feats against the older werewolf, but Deucalion outmaneuvers and outmatches him at every turn. Deucalion then takes out the dagger in his cane and stabs Scott.
Deucalion commends him on his werewolf ability, but reminds Scott that Deucalion isn't likely the one who's kidnapping and sacrificing innocent people. But his Pack does want Derek dead however, reminding Scott of Kali's vendetta. He lets Scott know the chances are that someone is going to die. Nonetheless, Scott demands that Deucalion tell him where Deaton is. Amused, Deucalion tells him a very important clue instead: "Let the current guide you."
Deucalion and Kali come upon Melissa McCall who curiously pulls the former's cane out of the wall. From behind, he takes the cane out of her hand and gives her his thanks. Melissa nervously realizes she's talking to the bad guy. The Alpha humors her, saying she has no idea of how much of a bad guy he is. He takes her hostage.
When they don't comply, Deucalion's Pack track Jennifer throughout the building. Kali gives chase on Jennifer and Derek. They escape into the elevator. Deucalion, however is prepared for this as he turns off the power generator, leaving the elevator stuck in the shafts.
He thanks Melissa for her cooperation. Melissa asks him what does he want with her now. Deucalion answers she's his gesture of good will and lets her go, telling her to go find Scott and advises her to be careful, to her confusion.
Kali mocks Deucalion that he has a soft spot for Scott. Deucalion answers her the young Beta is an investment he's trying to mature.
He tells Kali while they're talking about the soft spots, he requests they talk about Jennifer Blake. He's aware Kali has recognized Jennifer is actually
They argue over Kali's decision to let Julia Baccari die peacefully because she was harmless when Kali was to kill off her entire Pack to be a part of the Alpha Pack. Kalia insists Julia was harmless, but she tried to ill her anyway, because Deucalion wanted her to. Deucalion corrects her she joined the Pack to be with Ennis.
The lead Alpha goes on to cajole her on how harmless Julia looks now. Kali arrogantly admits there might have been a moment of when she was sure Julia was still fighting for life that she could have finished her off or just walked away and let someone she loved die in peace. Deucalion mockingly tells Kali his heart bleeds for her, but scolds her that Julia's could have bled a little more.
Deucalion listens to Scott's allies as they plan how to get Jennifer and Cora out of the hospital right out from under his Pack's noses.
Up on the hospital roof, a terrified Scott calls out for his mother. Deucalion arrives, telling Scott Jennifer took his mother, because as a parent, Melissa is a Guardian. The Alpha tells him he could have told him what 'Guardians' meant. Deucalion makes his terms clear: Scott joins his Pack and help him catch Jennifer; he'll help Scott rescue his mother and Stiles' father.
With a heavy-heart, Scott complies, ignoring Stiles' protests. Scott follows Deucalion into the night. Later on, Deucalion lets out a howl to tell the others to retreat.
Kali and the twins have cornered Morrell who's cast a mountain ash circle. Deucalion interrogates Morrell how she knew the Pack would come for her. Morrell tells her former Alpha she was aware that he's always been suspicious of what druids could do and that their reliance on her has been questionable because they know she hired the female warrior (Braeden) who rescued Isaac from them. The Alphas want her for information on Jennifer. Morrell replies she knows nothing more than they know.
The lead Alpha remarks "the lies people will tell when begging for their life". He then uncaps his cane and throws it into Morrell's shoulder knocking her over her circle.
The Alphas advance on Morrell, but Scott intervenes, tells his new Pack members no and to back off. In the end, Morrell's life is spared.
Deucalion meets with Scott atop Lookout Point at the night of the full moon and the lunar eclipse as Jennifer plans to kill all the Alpha Pack when werewolves everywhere are simultaneously powerless and she has already killed Kali and the twins are dying. Scott comes up with a plan. He leads Deucalion to the same abandoned building where Ennis declared vengeance. Scott sends a MMS video to Jennifer of the spiral carved into the wall knowing it's her true intent.
Scott and Deucalion wait. Jennifer arrives, along with a pressured Derek in tow. Jennifer had promised him the kidnapped parents if he would be her Guardian. Deucalion amusedly calls the standoff "brother against brother".
"Did you gather your herbs? Pray to your ancient gods and your oak trees? Slit a baby's throat, perhaps? Should we show them why you needed to sacrifice twelve innocent people just to face me? Or is it fifteen, now?"
The Demon Wolf then advances on Jennifer and shapeshifts into an ominous-looking demonic werewolf shape. Scott, Derek and the Darach are terrified at this display.
Derek makes the first move, shifting and roaring. The newly regressed Beta werewolf attacks Deucalion, but the Alpha swiftly blocks Derek's strike and left hand, being easily outmatched, and the Demon Wolf knows it.
Jennifer moves in and directs a telepathic blow at Deucalion. He easily resists and shakes the blast off. Cackling, the Demon Wolf then, in the blink of an eye, catches both she and Derek by the throats and lifts them both up. He knocks Jennifer down and duels with Derek again. Derek is overpowered and the Alpha easily flings him aside.
Jennifer advances again, but she's thrashed twice by Deucalion, and is then incapacitated. Scott has been motionless the entire time.
Deucalion holds a beaten Jennifer hostage. The Demon Wolf orders Scott to kill her. Scott hesitates. Deucalion Roars, forcing his Beta to unwillingly
Deucalion runs out of patience and rushes over to Scott, grabs him and forcefully walks him over to Jennifer, saying maybe Scott just needs a little guidance. Scott tells Deucalion to wait, that he forgot to tell Deucalion something he learned from Gerard: "Deucalion is not always blind."
Scott sneaks three flashbangs out of his pocket, and throws them against the floor, setting them off. Able to see in his werewolf form, Deucalion is now truely blinded by the devices. His new disability lasts until the lunar eclipse arrives.
Deucalion panics when the eclipse arrives, knowing he's lost his advantage. Jennifer has disappeared. She later reappears in her actual form, the Darach.
Jennifer has the power now and ruthlessly attacks, pummels and thrashes Deucalion, who's unable to do anything. He lays on the floor barely cognizant from his head injury. Jennifer prepares to give the Demon Wolf the final blow, but Derek stalls her by telling Jennifer that Deucalion doesn't know the price she paid from his bringing Kali into his Pack. Jennifer acquises, playing into Derek's trick to have Deucalion actually see what happened to her.
When Jennifer removes her hands, Deucalion blinks and is astonished, surprised, shocked that he can see again with human eyesight.
Jennifer then demands that Deucalion look at her to see the result of his crimes, before she kills him. The depowered Alpha looks at her scarred, depraved, dehumanized face, to his horror. Jennifer however has been rendered weak by her healing him, as Derek had intended.
When the lunar eclipse passes, and Jennifer recovers her power, she casts a mountain ash circle. Soon her quintuple sacrifice will be complete, and then she won't need a lunar eclipse to kill even Deucalion. Scott however takes action and forcefully pushes against the mountain ash, fully determined to stop Jennifer. Scott keeps pushing on and on, breaking the suprnatural barrier. A newly empowered Deucalion watches in awe, inspired at this display and witnesses as Scott fully awakens his True Alpha status, fully overcoming Jennifer's barrier.
Scott seriously says he's now an Alpha and demands Jennifer stop the storm or he'll kill her himself.
Reminded of humanity, Deucalion steps in, saying killing her won't change his werewolf eyes. So the repentant Alpha decides to prevent Scott from becoming a killer, and does it himself, slashing Jennifer's throat, mortally wounding her. Jennifer falls back, incapacitated, as her true form. The storm stops with Jennifer's threat put to an end.
The two Wolves then leave a solemn Deucalion alone.
Deucalion becomes aware the Calavera family of hunters have captured Derek. Having also found out the mercenary Braeden survived his attempt to kill her, he hires her to rescue Derek from the Calaveras. Braeden accepts his job, heading to Mexico to save Derek.
Theo and his Pack start tracking down Deucalion, which Scott finds out through Mason, via Corey.
Scott finds Deucalion first and puts two and two together that Theo wants to learn from Deucalion how to steal the power from the Beast of Gevaudan. To repay Scott for sparing him months last year, the True Alpha alerts the Deucalion of this, then enlists him to undermine Theo. Deucalion accepts and presents himself to be blind again+ .
Theo's Pack, Tracy, Corey and Josh find Deucalion and after great strife and pain on their part, they bring him to the The Dread Doctors' operating theatre. Deucalion is hooked up to a contraption injecting the trapped Alpha with wolfsbane to weaken him.
The blind Alpha tells Theo he knows about the resurrected Beast of Gevaudan and that he wants Deucalion will show him how to steal its power. Theo, pleased, thinks Deucalion wants to make a deal. He invites the trapped Alpha to just tell him what he wants.
Deucalion: "I want his eyes. On the tips of my claws. I want the eyes of Scott McCall."
