As of the end of Season Three, major changes happen to the cast that affect the entire continuity of the show; spoilers will be unmarked. YOU HAVE BEEN WARNED. Beware: only developments of the newest season will be spoilered. (Right now, that's Season 5.)
General hunter tropes:
- Badass Family: All hunter groups are lead by a central family, which is in turn lead by a matriarch, usually the eldest daughter or the wife of the eldest son.
- Code of Honor: The traditional Hunter's Code was coined by the Argent family, who apparently were the first organized werewolf hunters: We Hunt Those Who Hunt Us. Allison Argent later decided to turn her family into guardians of innocents both human and supernatural and changed their code to We Protect Those Who Cannot Protect Themselves. Chris Argent follows the code of his daughter, while other hunters follow the former Hunter's Code.
- Electric Torture: One of their most common "interrogation techniques" when it comes to werewolves. According to Chris, it was also used to "test" werewolf stamina and healing properties.
- Hunter of Monsters: They are werewolf hunters and they are very thorough.
- Jack Bauer Interrogation Technique: Both Araya Calavera and Gerard Argent love to use this; Araya especially enjoys cutting off limbs, while Gerard isn't above beating up even averagely human teenage boys.
- Knight Templar: They are convinced they are protecting the normal human world from supernatural threats, to the point where they don't really pay attention if what they hunt really is a threat.
- Meaningful Name: Both hunter families we've met so far have Names to Run Away from Really Fast: Argent means silver in French (and the Argents are the reason werewolves are said to be vulnerable to silver), while calavera is "skull" in Spanish.
- Those Who Fight Monsters: A lot of the hunters seen are considerably violent and often more brutal than the creatures they fight.
- Well-Intentioned Extremist: Most of them truly want to protect people, or least think they do.
The Argents are the first family of hunters that appear in the series. They are a noble family of werewolf hunters, with a tradition that goes back to 18th century France. Their US American branch is currently in shambles, after the death of the last two family leaders.
Kate Argent (portrayed by Jill Wagner)
Allison's sexy but sociopathic, genocidal aunt, who refuses to abide by the Hunter's Code that most of the Argents follow and is a villain of Season 1. Kate is revealed to be the one who orchestrated the Hale house fire, killing most of the Hale family. She is killed by Peter Hale in vengeance for the fire except ...
She never actually died. She transformed into a were-jaguar, because Peter killed her with his claws, as was revealed in the final scene of Season Three setting her up as one of the villains for Season 4.
- Ax-Crazy: And she'd gladly chop a werewolf in half with one, too.
- Big-Bad Ensemble: With Peter Hale, for Season 1, after she returns to Beacon Hills and begins hunting down the Alpha Werewolf.
- Belligerent Sexual Tension: With Derek. As a teenager, he was in love with her, while she seems to have been playing him to get closer to his family.
- Blood Knight: On some level, Kate might indeed think that killing werewolves is best for humanity, but, looking at her actions, you get the feeling that she enjoys it a bit too much to be anything but lucky for the handy 'but it doesn't count, they're not human' excuse to kill people.
- Cool Big Sis: Allison describes her as more like her sister than her father's. Whether this attitude was sincere familial affection or the desire to follow in daddy's footsteps by crafting her own psychopathic werewolf-killing machine is debatable.
- Cool Aunt: Kate's the fun aunt, the one you can talk to about your problems...
- Cute and Psycho: ... she's also the kind of aunt who thinks a good aunt-niece bonding exercise is torturing somebody.
- Daddy's Little Villain: Kate's much more ruthless than her brother and doesn't follow the Hunter's Code, something that Gerard took great pride in.
- Dark Action Girl: She's just as willing as the male hunters to take up weapons and fight to kill the werewolves in Beacon Hills. And the killing of innocents throws her into the darker reaches of the trope, too.
- Dragon Ascendant: It's implied she was once Gerard's dragon.
- Ephebophile: Seduced Derek when he was a teenager to get the information she needed to murder (almost) the entire Hale family, and made some (in hindsight) creepily complimentary comments about Scott when she first met him, specifically his "puppy dog eyes." She also expresses appreciation for Jackson. It's unclear how much of this is her using her sexuality as a weapon, how much is her enjoying claiming power over others, and how much might be genuine attraction, but she certainly doesn't rule out teenage boys.
- Even Evil Has Loved Ones: Kate might be one of the worst villains in the show, but she won't hurt her brother if she has another option. It also applies to Allison, who she had several Pet the Dog moments with, and attempts to avenge after her death.
- Fantastic Racism: She hates all werewolves. But as if to illustrate how depraved she is, she is apparently quite willing to have sex with them for all that she considers them to be inhuman.Kate: Oh, this one grew up in all the right places. I dont know whether to kill it or lick it.
- Femme Fatale: She used her charms to endear herself to a younger and more naive Derek, which later led to her slaughtering the Hale family.
- Interplay of Sex and Violence: Kate always uses highly sexualized language when talking to Derek, even (or especially) when causing him harm.
- It's Personal: In Season 4, Kate blames Scott and his friends for Allison's death claiming they killed her, and blames Scott for the decimation of her hunter family to the point she turns Scott into a new Berserker to use him against his friends and have them kill him.
- Karmic Transformation: The hunter of were creatures, turned into a were jaguar. By the guy she drove insane by killing his family and putting him in a coma, no less.
- Meaningful Name: Katherine can mean "to torture." Guess what Kate likes to do to werewolves?
- Not Quite Dead: Peter slashed her throat in the Season 1 finale, seemingly killing her. She returns at the end of Season 3, having been turned into a were creature instead.
- Pet the Dog: Despite Kate's awful attitude towards werewolves, she is a loving aunt to Allison. In "Lunatic," She comforts a sobbing Allison over her boyfriend - right after encouraging Allison to tase a teddy bear.
- Psycho Supporter: Of her father, from whom Kate learned all of her... genocidal craziness.
- Psychotic Smirk: When she's killing werewolves, oh yes.
- She Who Fights Monsters: Kate's a lot more ruthless and violent in her methods than almost all of the werewolves she's hunting. She's also willing to use innocent humans as collateral damage if it's necessary.
- The Sociopath: She'll happily kill any werewolf who crosses her path, even if they've never hurt another person in their whole life. And humans who get in the way are just collateral damage.
- Terms of Endangerment: Calls everyone sweetie. Even when she's torturing them.
- Would Hurt a Child: If they're a werewolf or associated with werewolves, as demonstrated by her burning of the Hale house, which killed several humans and young children.
Gerard Argent (portrayed by Michael Hogan)
Allison's grandfather and Chris and Kate's father, who also refuses to follow the Code. After Kate is slain, he begins leading a genocide against any and all werewolves within Beacon Hills, manipulating multiple people to do it. This puts him into conflict with Chris, who notices that Allison is beginning to fall under his sway as well.
- Abusive Parents: He molded his daughter into a genocidal lunatic and was willing to kill his own son and granddaughter to cure his cancer by becoming a werewolf.
- Archnemesis Dad: Allison does her best to undermine his plans to murder Scott until he uses her mother's death to pull her over to his side. After that, Chris, who was already critical of his father, begins to turn against him in earnest.
- Ax-Crazy: He can be just as crazy as Kate in his pursuit of ridding the world of werewolves. And if he could take an axe to them all, he gladly would.
- Big-Bad Ensemble:
- He a Big Bad in Season 2, seeming to want revenge for Kate's death at first but later it turns out he's dying of cancer and wants to become a werewolf to survive. He shares the spotlight Kanima Master, whose identity is revealed to be Matt Daehler until he ends up killing Matt and assumes the role of the Kanima Master, thus becoming the ultimate threat on his own.
- Then in Season 6B, alongside the Anuk-Ite.
- The Bus Came Back: In Season 5, when Chris reluctantly decides to recruit him for information and help with the Dread Doctors' success, the Beast of Gevaudan.
- The Chessmaster: He spends nearly all of season two playing everybody around him like a fiddle, including his own granddaughter.
- The Dreaded: Feared by pretty much everyone, including his own family.
- Evil Cripple: After Season 2, because he'd been Bitten but Scott drugged him with mountain ash and he's been confined to a wheelchair and coughing up Bad Black Barf ever since. The Argents set him up in a retirement home where he stays until Chris recruits him to help against the Dread Doctors in 5B.
- In Season 5, he is given a cure by Chris, to be able to help against the Beast.
- Evil Mentor: He was this to Kate in her younger years when it came to hunting and murdering werewolves, then to a vengeful Allison in Season 2. In Season 6, he's now taken burgeoning hunter Tamora Monroe under his wing.
- Evil Old Folks: Gerard's so bent on killing werewolves that he's willing to beat the snot out of Stiles, a human teenager, in order to send a message of intimidation to Derek and Scott. He also murders Matt to become the master of the kanima, and is willing to sacrifice his family to secure his own survival.
- Fantastic Racism: He's the one who taught it to his daughter, so no questions there.
- Faux Affably Evil: He lampshades this himself when monologuing to Scott (with a knife in Scott's stomach) about how good he is at playing the doddering old grandfather.
- Freudian Excuse: He claims that Deucalion bit his brother Alexander and caused him to commit suicide, implying that this is why he attacked Deucalion.
- He Who Fights Monsters: Any credibility his 'werewolves are monsters' rhetoric might have falls flat in the face of his being a more sadistic predator than Peter at his worst.
- Hypocrite: Hates werewolves and plans to kill them all, but his master plan involves becoming one to cure his cancer. This is revealed after he basically forced his daughter-in-law to kill herself - and his son to assist her suicide - when she is bitten. Also dismisses Kate (a werejaguar) as "one of them" in season 6, despite the fact that, if his plan had worked, he himself would have been a werewolf for almost as long.
- I Have Your Wife: Gerard has a terrible habit of holding the lives of loved ones over Scott's head. Most prominently, Scott's mom. Turned Up to Eleven during the final lacrosse game, where he threatens Stiles, Allison, and everyone present.
- It's All About MeGerard: When it comes to survival, I'd kill my own son!
- Jerk with a Heart of Jerk: Bisects homeless Omegas, gaslights his family members, and blackmails teenagers into doing his bidding by threatening to kill their loved ones. And that's after turning his daughter into a homicidal maniac.
- Karmic Death: After years of being a monstrous bastard for his own gain, Gerard meets his end at a mortally wounded Kate's claws and fangs, ripped apart by the daughter he manipulated and abandoned.
- Karmic Transformation: After the interplay of Derek's bite and the pills with mountain ash he consumed due to Scott's intervention, he's still alive, but unable to do much more than leak black blood. Until Chris provides him with a cure in Season 5.
- Manipulative Bastard: Uses Scott's mother to control Scott, all but forces Victoria to commit suicide, then uses her death to shape Allison into Kate 2.0.
- Offing the Offspring: He's willing to murder his son and granddaughter in order to guarantee his own survival. Finally, in the series finale he shoots his daughter werejaguar Kate with a yellow wolfsbane bullet, because he doesn't see her as his daughter anymore.
- Old Master: Despite his advanced age, Gerard scares the crap out of everyone around him, and with good reason. He's still fit enough to bisect werewolves with the Argent family sword, and personally beats up or even murders teenage boys when necessary.
- The Patriarch: Despite Season 2 being the season where it's first brought up that among hunters, men are soldiers and women are leaders, Gerard takes complete control of hunter operations in Beacon Hills from the word 'go' for basically no reason other than being Chris's dad.
- Patricide: How Gerard finally meets his end, at the hands of the daughter who had been every bit the unrepentant sociopath he had been.
- Roaring Rampage of Revenge: He claims that he has decided that werewolves can no longer be allowed to continue existing because of the death of his daughter at the hands of one; as if he needed the excuse to set off a genocidal crusade.
- The Sociopath: He's just as crazily bent as his daughter about committing genocide against all werewolves in Beacon Hills. And probably the rest of the world, if he was given half a chance.
- This Means War!: Kate's death is the catalyst for his Roaring Rampage of Revenge against werewolves.
- Token Evil Teammate: In Season 5B, he's recruited by his son to help fight against the Beast. Of course he plans to double cross the pack in the end, but for once, they anticipated it, and double cross him first.
- Van Helsing Hate Crimes: Even his own son, a fellow werewolf hunter, refers to Gerard's intentions as genocide.
- Villainous Breakdown: Has one when he finds out Scott pulled a Batman Gambit on him. His exact words?Gerard: KILL THEM ALL!!!.
- Wicked Cultured: Has a tendency to quote Shakespeare at the slightest provocation.
- Would Hurt a Child: In Gerard's eyes, anyone associated with or connected to werewolves needs to die. And this includes human teenagers like Stiles, who's nothing more than a means to an end in Gerard's opinion. He is not impersonal about it either, using the Kanima to threaten the life of his own granddaughter. Also, despite his supposed anger over his daughter's death, he states flat out that he would sacrifice his son's life if it helped his own survival - while said son is standing right in front of him.
- You Monster!: By his son Chris, when he threatens Allison's life to blackmail Scott.
One of Chris' uncles, who died prior to the series, committing suicide because he was turning into a werewolf. Gerard claims he blinded Deucalion because he was the one who bit Alexander.
Marie-Jeanne Valet (portrayed by Crystal Reed)
The original huntress, she was the one who slayed the Beast of Gévaudan - her own brother, Sebastien. She was helped by Henri Argent, a young man well-versed in the supernatural, who became her partner and eventual husband.
- Action Girl: Marie-Jeanne is a noted hunter and wields crossbow, knife and spear like she's born for it.
- Beast and Beauty: Played with and deconstructed: Marie-Jeanne is beautiful, loving and assertive, but her beast is not her lover, it's her own brother, and their love tips over into mutual hatred as soon as Marie-Jeanne discovers Sebastien's secret. Her love also doesn't save him - she ends up killing him, and he is unrepentant.
- The Determinator: After Sebastien escapes her, she hunts him for three years, until she finally finds and kills him.
- Historical-Domain Character: Marie-Jeanne Valet was a young woman who was attacked by the Beast of Gévaudan, but managed to save herself and her younger sister by stabbing her attacker with a self-made spear. Francois Antoine, the royal hunter assigned with taking down the Beast, praised her bravery and recommended her for a reward.
- Identical Granddaughter: Marie-Jeanne is played by Crystal Reed, and thus looks exactly like her descendant, Allison Argent. This isn't just a way to get Crystal Reed back on the show for an episode and give this character a familiar face; Sebastian explicitly saw Allison in Scott's memories, confused her for Marie-Jean, and that played a critical role in his defeat.
A hunter family based in Mexico, they are strict followers of the Hunter's Code and make it their responsibility to enforce it even across the border. They are sometimes reluctant allies to Scott and his Pack and even function as The Cavalry in one memorable occasion. They've agreed to leave Scott's Pack alone as long as they prove able to live peacefully with humans.
Araya Calavera (portrayed by Ivonne Coll)
The current leader of the Calavera family, and a formidable, but ultimately fair woman.
- Ax-Crazy: She might love violent interrogations a little too much.
- Anti-Hero: Her methods, while ultimately often helpful to the heroes, are really less than morally sound.
- Badass Normal: She's just a human, and elderly at that, but she will come out with her boys to fight were jaguars and berserkers if necessary.
- Badass Boast:Araya: Come, La Loba! Let me show you how the Calaveras die!
- Cool Old Lady: She's scarier than a whole pack of Alphas, and a fan of modern dance music.
- Determinator: Since Kate transformed into a werejaguar on her watch and killed multiple members of Araya's hunters group in the process, she's dedicated to bring her down and won't let anything sway her from her path.
- Even Evil Has Standards: Araya can be violent sometimes amoral in her hunter operations, though she's willing to make compromises if it suits her purposes. When Scott's Pack broke into her base, though she had Scott tortured, she released them on the basis they would be helpful in dealing with Kate. Later on when its clear that Scott had Bitten an innocent - Liam - she kept her word to Chris' deal that he'd help them catch Kate in that she'd leave the supernaturals in Beacon Hills in peace, regardless.
- Face Death with Dignity: Araya doesn't even let a lethal were-jaguar and unstoppable Berserkers get to her. See Badass Boast above.
- Good Is Not Nice: She sees herself as a protector of the human world and thus "good" by default, but she values intimidation and torture as means to deal with supernaturals, and uses murder to keep her hunters in check.
- Kick the Son of a Bitch: In Season 3B, when she tortures Peter Hale while he and Derek are held captive by her family.
- Psychotic Smirk: Araya is often cynically amused at the world, especially when carrying out the nastier duties of her calling. If her cold demeanor doesn't intimidate you, her smile certainly will.
- Reasonable Authority Figure: Despite her more unscrupulous methods, she's not against giving interlopers and enemies a chance to explain to explain themselves, and similarly is willing to let them live if they prove to have similar intentions to the Calaveras.
- Well-Intentioned Extremist: Araya does truly mean well for the sake of humanity; she's just quite brutal towards werewolves. What keeps her on the side of good is that she doesn't go too extreme in her methods, and only hunts those who harm humans (as opposed to, say, Gerard, Victoria, or Kate).
Severo Calavera (portrayed by Ivo Nandi)
Severo is Araya's right-hand man, who follows her orders unquestioningly. It's unclear if he's her son, nephew, or much younger brother.
- Foil: He occupies the same role in his family as Chris Argent did for the Argents, but seems perfectly happy to follow orders without possessing Chris' conscience and sense of morals.
- Meaningful Name: Severo means strict. It's hard to imagine him smiling.
- Number Two: To the Calavera's leader, Araya.
- Perpetual Frowner: Severo seems to be constantly irritated.
- The Quiet One: He doesn't talk much, leaving the role of spokesperson to Araya.
