- Portrayed By: Sam Witwer
A vampire who was a merciless killer for over two hundred years before he decided to clean up his act.
- The Atoner: He is continually trying to make up for all the things he has done over centuries as a vampire. He also on several occasions has to atone for his actions to his roommates for the things he does to them and when he gives in to his vampire nature.
- Being Good Sucks: He continually has to fight his vampire urges and deal with other vampires and other factors tempting him to go back to his old ways. Fighting his urges and being a vampire results him having to end romantic relationships and not having very many friends as people who are associated with him either end up getting killed or having their lives ruined.
- Also most of the bad stuff he goes through or does is because he is trying to help or protect Sally, Josh, and the other people he cares about as he is forced to make dark choices that sometimes make things worse.
- Beware the Nice Ones: He is a genuinely affable and easy-going guy most of the time, but he is still a 200+ year-old vampire; with the abilities that come with that, and his bloodthirsty instincts are only barely under control at all times.
- Big Brother Instinct: To Josh.
- Buried Alive: In the season 2 finale.
- Byronic Hero: Displays several of the typical traits; physically attractive, charming, brooding, intelligent, having a Dark and Troubled Past and being (very) internally conflicted. Lampshaded in his first scene, where he is shown quoting Lord Byron's poetry during his date with Rebecca.
- Cain and Abel: With Marcus sort of since they're vampiric "brothers". However in the 4th season with Sally having altered the events of the show Marcus and Aidan are shown to be on excellent terms as they laugh and get drunk on blood together. Marcus even remarks this "So good to see the Aidan I know and love is back".
- Cartwright Curse: To a ridiculous degree. Lampshaded by Henry.
- Chick Magnet: Had several female lovers over the years and also attracts some of his hospital co-workers.
- Dark and Troubled Past: As a vampire spent centuries murdering people and of course having to leave his family when he is turned into one.
- Death Seeker: During the Season 3 episode I'm so Lonesome I Could Die.
- Defiant to the End: Mixed with Heroic Sacrifice. When it becomes clear he isn't getting out of Liam's torture chamber alive, Aidan tries to protect Nora by lying about having killed Brynn, taunting Liam about how she begged for mercy. Josh manages to rescue him in time, but not before Liam gives him a shot of infected blood.
- The Dragon: Used to be this for Bishop, before his HeelFace Turn.
- Mr. Fanservice: Oh my, yes.
- FaceHeel Turn: He was a kind, honorable man as a human, and even after initially being turned into a vampire. Unfortunately, the hunger for blood, losing his family, and Bishop's influence, turned him into a sadistic murderer for just under 200 years.
- In season 4's alternate timeline.
- FaceHeel Revolving Door: Season 4 shows that Aidan has a sordid history of this. Consistently Jumping Off the Slippery Slope into villainy, then later becoming The Atoner and a Friendly Neighborhood Vampire to make up for his horrible deeds.
- Throughout the series he is trying to prevent himself from doing this but he sometimes is forced to commit murder and other immoral actions to protect and help the people he cares about. Then there is also the things he does in dealing with his thirst for blood.
- Fascinating Eyebrow: His eyebrows are incredibly expressive.
- Fate Worse than Death: Mother claims the 'eternal madness' of being being buried alive is this. However Aidan considers her killing of Suren to be hers.
- Friendly Neighborhood Vampire: Aidan tries but lapses frequently.
- Good Parents: In flashbacks, he is shown to be a loving father, who had a good relationship with his son, Isaac.
- Happily Married: He and his wife Suzanna had a strong relationship during their human life.
- HeelFace Turn: Was a murderous vampire who was famed for his cruelty for over 200 years, but in the 1970s, he decided to leave Bishop and the Family, stop murdering people, and only live off blood bags.
- Hell-Bent for Leather: Wears a black leather cafe racer jacket most of the time. He even puts it on before knowingly going to his final death in the finale.
- He's also seen wearing a different, 70's-style black leather jacket in a flashback to the 70s, and a more contemporary brown leather jacket after his FaceHeel Turn in season 4's alternate timeline.
- Heroic Sacrifice: He burns down their now abandoned house, with himself inside to destroy the murderous evil spirit inhibiting it.
- Heterosexual Life-Partners: With Josh.
- Humanity Ensues: Aidan becomes human at the end of season 4.
- I Hate You, Vampire Dad: Zig Zagged with him and Bishop. He initially hated Bishop for turning him into a vampire, but once Aidan made a FaceHeel Turn and accepted the vampire way of life, he and Bishop were quite close for the next 200 and so years. When Aidan made a HeelFace Turn in the 1970s and decided to be a Friendly Neighborhood Vampire, he wanted nothing to do with the unrepentantly murderous Bishop anymore.
- I Love You, Vampire Son: Towards Henry and Kenny. He turned both of them out of gratitude for saving his life, and shows Papa Wolf / Big Brother Instinct tendencies towards both of them.
- Inept Mage: Vampires have Hypnotic Gaze but you have to practice to be good at it. Aidan doesn't and isn't.
- Nice Guy: Was this during his human life. After he became a vampire...not so much, but he is trying to be this again during the series.
- Nice Job Breaking It, Hero!: While Sally is the queen of good intentions gone bad, Aidan is undoubtedly the king.
- Off the Wagon and onto somebody's neck.
- Parental Substitute: To Bernie, briefly.
- A bit more complicated with his vampire "sons", Henry and Kenny. He's protective of them, both are consistently referred to as his "son", and Aidan is certainly old enough to be their father. However, their close physical ages and relationship dynamic makes Aidan come across as more of a big brother-type figure instead.
- Perma-Shave: Is almost always seen with a close, clean shave. The exceptions are a few flashbacks when he has a mustache, and when he grows a beard after being buried underground for over a year.
- Villain Protagonist: In most of the flashbacks that take place during his life as a vampire.
- Vitriolic Best Buds: With Josh. They can tease eachother and can make remarks at the other's expense, but they are undoubtedly loyal to eachother, and save one-another's lives more than once.
- Marcus and Aidan's original relationship seems to have been this before Aidan left and went vegan.
- Warm Bloodbags Are Everywhere: Vampires often link blood and sex and Aidan does draw the ladies' attention.
- With Friends Like These...: The scene between Aidan and Marcus in the blood den during "Rewind, Rewind" seems to show that their relationship was more like this originally before Aidan left.
- Portrayed By: Sam Huntington
Josh was a premedical student before getting turned into a werewolf.
- Badass Normal: During the time that he's cured. The self-esteem and perspective he gets following the events of the season 2 finale end up pushing him to become the most heroic member of the cast in season 3.
- Empowered Badass Normal: The badass factor doesn't go away after Liam curses him again.
- Blatant Lies: But is terrible at it.
- Despair Event Horizon: Julia's death causes this. He blames her death on Ray.
- Hollywood Nerd
- Fantastic Religious Weirdness: Josh is still Jewish, but no longer very observant, as he feels that Judaism would frown on the whole turning-into-a-wolf thing.
- Heterosexual Life-Partners: With Aidan.
- Humanity Ensues
- Humans Are the Real Monsters: While Josh would fervently deny this, almost all the destructive and selfish things that he's done have been a result of his decisions as a human, not his lycanthropy or actions as a wolf.
- I Am What I Am: Near the end of season 4, he finally accepts his wolf and thus gains control over it after resenting it for so long.
- I Just Want to Be Normal
- Informed Judaism
- I Hate You Werewolf Dad: His relationship with Ray. This will most likely carry over to Liam now that he's been infected again.
- Aidan solves the Liam issue by himself.
- Kick the Dog: His premeditated murder of Ray. When he faces Ray again in season 3 he taunts a wolfed out Ray that he'll visit his son next and kill him too.
- Mistaken for Gay: By Danny. And his parents, much to Aidan's amusement.
- Mysterious Animal Senses: Around his "time of the month".
- Neat Freak: Likes to keep the living arrangements tidy, and making a mess is a good way to annoy him. In season 3, Nora tells him to not clean-up after Aidan, after Aidan throws a frat party in the house. Josh says he won't clean...cue Gilligan Cut to Josh finishing a clean-up of the mess.
- Only Sane Man: Of all the characters in the show, Josh is easily the one that tries hardest to be human.
- Our Werewolves Are Different: After being turned a second time and passing through Donna's door, Josh became what can best be described as a reverse werewolf, being stuck in wolf form throughout most of the month and only becoming human again on the full moon. Sally uses blood magic to reverse this, but the spell was not completed correctly, and though Josh is now mostly human, he is still very much affected by his wolf throughout the month, having extreme mood swings and turning when he least expects it. As far as we know, he is the only werewolf in existence that can turn without a full moon. It is later revealed that this is because of his several years of attempting to suppress and eliminate his inner wolf, who has become fearful of Josh, particularly after he has been cured. Once Josh was re-cursed, the wolf decided to take the wheel until Sally helps Josh come to terms with the wolf.
- Papa Wolf: Josh has become one for his adopted family. Ironically, he's more of a wolf as a man protecting his family than he ever was as an actual werewolf. Even Liam is impressed.
- Perma-Stubble: For the first 3 seasons, he always has a few days worth of facial hair growth, but not an actual beard. In season 4, he has grown a full beard.
- Status Quo Is God: Spends most of the third season as a human once he kills Ray. Comes to an end when he attempts to save Aidan and winds up getting injured by Liam.
- Shapeshifter Mode Lock: For three months after the events of the Season 3 finale. It gets bad enough that he starts to forget what it's like to be human.
- Team Mom
- Took a Level in Badass: After he kills Ray. The submissive, non-confrontational Josh of the first two seasons is gone in season three, replaced by a Josh that is confident and not afraid to face danger head-on (or even to take a life) to protect his family.
- He becomes incredibly powerful after his curse worsens, to the point where he can single-handedly fight off multiple vampires without the influence of the full moon.
- Took a Level in Jerkass: His anti-social personality worsens in season 4, to the point where Nora feels the need to sleep with a knife under her pillow. In the alternate timeline Sally creates, alternate Josh is incredibly put off by her presence and so dismissive of her pushing him into a relationship with Nora, he gives up on relationships completely.
- Villain Protagonist / Well-Intentioned Extremist: During the season 2 finale when he plans to kill Ray. He does claim to do it to cure Nora but it's clear he blames Ray for Julia's death.
- Vitriolic Best Buds: With Aidan. They can make fun of eachother and have their disagreements, but they still have an Undying Loyalty to eachother.
- Wolf Man
- World's Strongest Wolf: As previously stated, when transformed he's a deadly fighter even by werewolf standards. His wolf is also described as being particularly terrifying due to its extreme viciousness, caused by Josh constantly restraining it and denying it a chance to hunt. It's still no match for a Purebred, though. Until the effects of his lycanthropy are enhanced by Sally's spell, after which it's easily the single most powerful and most aggressive werewolf in the series, possibly even the most powerful supernatural creature in general.
- You Sexy Beast: Due to his lycanthropy, he is sexually aggressive towards Nora when they start dating. While making out and having sex for the first time, he starts growling.
- Portrayed By: Meaghan Rath
An impulsive young ghost who is trying to find her place in the world now that she's dead.
- Ambiguously Bi: Sally tends to come off as this on occasion. For instance while talking at Emily, Josh's sister, she says she could make her feel happy. And when Nora comes over, Sally promptly quips that she's hot and has nice boobs.
- Axe-Crazy: After it's revealed that the Reaper is actually her.
- Back from the Dead: She was brought back from Limbo via Blood Magic in Season 3, meaning she temporarily had a corporeal body again.
- Butterfly of Doom: After Sally uses magic and is sent back in time to the night she died, she decides to save herself from her own death at the hands of Danny. As she still possesses knowledge of her life with Aidan, Josh, and Nora, she tries her best to rewrite history with herself still part of their lives but saving them from all of the problems that befell them. This backfires entirely on her: Bridget dies when she dates Danny leaving her to suspect Danny killed her. She becomes a werewolf instead of Nora, keeping Josh and Nora from ever becoming close. And when she and Aidan fall in love, it only drives Josh away from them and with Ray, ultimately resulting in her death, again, which in turn prompts Aidan to return to his position as Bishop's right hand man, and Nora into a life of stealing painkillers at work.
- Came Back Wrong: Her plot in season 3, when she is reanimated and later has to consume human flesh to keep from rotting..
- Cute Ghost Girl: Naturally.
- Deadpan Snarker: She has her moments.
- Dragged Off to Hell: What appears to be her fate at the end of season 3.
- Season 4 reveals this is effectively the case, though it was to a place better described as a space between worlds to prevent Sally from causing irreparable harm to the universe. She gets out.
- Enemy Within: The Reaper as stated is her second personality.
- Ghost Amnesia: Sally is initially unclear on the circumstances of her death.
- Ghostly Goals: She has the desire to move on by getting her door and generally has the desire to connect with people and have back her human senses like touch and taste.
- Hand-or-Object Underwear: While in an illusory spa in Season 4.
- Heroic Sacrifice: Gives up her spiritual essence to turn Aidan Human, effectively destroying herself.
- I'm a Humanitarian: After she renegotiates her deal with Donna, she has to consume living flesh in order to prevent her undead body from rotting. When she finds herself staring into a pet shop window in hunger, and then turns to set that gaze upon a child, she realizes what she's become and decides to never cross that line. She does take a bite out of Aidan out of necessity though. She complains that it's like trying to bite into a tire because he's subconsciously flexing.
- Jacob Marley Apparel
- The Killer in Me: Though it's more like The Grim Reaper in me.
- Laser-Guided Karma: Lampshaded by Zoe, when Sally got possessed by Max's mother to force her to break up with him since possessing people is what she did when she was a ghost and got addicted to.
- Mind over Matter: May depend on her stress level.
- Nice Job Breaking It, Hero!: Sally's attempts at helping people almost always backfire in some way.
- One example is when after being brought back from the dead she is explicitly told not to see anybody from her past and when she goes out to party with Josh and Aidan she is recognized by Trent who is an old friend from high school and it is stated that subconsciously she went out because she wanted to run into somebody from her past and makes very little attempt to convince Trent that he made a mistake in recognizing her and instead parties with him and takes him home with her attempting to seduce him. The next day he dies and it turns out that is the consequence of seeing people from her past.
- The tendency for all the things that she does to help backfiring is lampshaded by the other characters and is described by Josh and Zoe as "Sallying things up" and this is the reason that Donna destroys her death spot and traps her in limbo when she gains witch powers as she knows that Sally could unintentionally cause damage to the world with those powers. In season 4 Donna is shown to be right about this as after Sally escapes from her she uses her powers and unintentionally causes problems including stopping her own death and creating an alternate timeline and in trying to make things like the original one she ends up making life worse for her roommates and others eventually leading her to die again. Also her magic using wakes up the evil in the house.
- Nightmare Fetishist: Sally definitely has her moments, such as her conversation in the Season 2 finale where she urges Josh to carve up Ray with some garden shears rather than shoot him.
- Ninja Pirate Zombie Robot: In season 4, she becomes a time-traveling ghost witch werewolf, possessing her own body, in the past, from the future
- Not Using the "Z" Word: In season 3 Sally abhors being called a zombie or implying that her deterioration is actually the act of decomposition.
- Official Couple: She and Aidan become a couple in the alternate timeline and when she comes back to the original timeline she eventually expresses her feelings for him.
- Our Ghosts Are Different
- Refusal of the Call: In Season 3, Sally no longer wants anything to do with trying to help ghosts and other people as it has always ended badly for everybody. She goes so far as to disperse ghosts who try to ask her for help. She turns around by Season 4.
- Sanity Slippage: Season 2 reveals that she began going insane after missing her door, and only snapped back to reality after shredding herself.
- Set Right What Once Went Wrong: After being sent back in time to the night of her death, she manages to merge with her past self and now Trapped in the Past decides to use her knowledge of her life with Josh and Aidan to make their lives in this timeline better, but only makes things worse.
- She Cleans Up Nicely: Her dream self certainly does.
- Even more so after being reanimated. Straightened hair and snazzier clothes did a wonder for her appearance.
- Ship Tease: Has some moments with Aidan in season 3 when she is reanimated with the first being when they are holding hands on the couch together and stopped because it was getting weird and generally becoming closer friends. They become a couple in season 4.
- Status Quo Is God: Sally's reanimated body gives out in the second-to-last episode of season three. The bright side is she's at least in a new dress and not wearing her pajamas anymore.
- Together in Death: She is reunited with Aidan in the afterlife, after he dies in the house fire and his ghost gets a door.
- Twofer Token Minority: For most of the show run, she's the only person of color (Indian-American, it turns out) and a woman too.
- Villain Protagonist: When she's revealed to be The Reaper and in the Season 2 finale when she assists in planning Ray's murder, even possessing Ray's wife in order to lure him to his death. "Scott" even calls her out on it.
- Villain Ball Magnet: Every time Sally says the phrase "I can help" expect the lives of everyone around her to be worse off than before she met them.
- Voice of the Legion: When the Reaper is talking through her.
- Whodunnit to Me?: The house shaking turns out to be revealing that her fiancé was responsible for her death.
- You Can See Me?: In the pilot, when discovering that Aidan and Josh can see her.

- Dark and Troubled Past: She once had a boyfriend who mutilated her stomach. Then she ate him.
- Her family life wasn't that great, either.
- Deadpan Snarker: Has a habit of this especially after becoming a werewolf and dealing with it.
- Fanservice: Waking up naked in the woods after transforming.
- Horrible Judge of Character: A huge flaw of her character; her ex-boyfriend, in her backstory. Brynn, in season 2 and Erin, who has a history of violence and running away; that she completely ignores.
- Kick the Dog: Instead of trying to defuse the situation, she decides to help Josh kill Ray and shoots him.
- Lack of Empathy: Her monologue to Josh in Season 2 Episode 7 that she is not afraid that she killed her ex-boyfriend but rather that she doesn't feel any remorse about it.
- By season 3, this has changed.
- Muggle: At first...
- Our Werewolves Are Different: It would seem that wolves turned from humans with a lot of emotional baggage (an abusive boyfriend, in Nora's case) are even more violent, since their built-up anger is not inhibited in wolf form. Nora also reveals that she can remember everything from her transformations, which is probably due to her being more accepting of the transformation than Josh.
- Scars Are Forever: They even appear on her werewolf form.
- Her scars have now been healed as of Season 4, thanks to Sally's newfound magic powers.
- Sixth Ranger: Supporting cast throughout season 1 until the finale when she's turned into a werewolf by Josh, and becomes the fourth roommate.
- Took a Level in Jerkass: In Season 3, after taking in Erin as her legal guardian, she become increasingly hostile towards Aidan, even after Erin poisons him and tries to kill him resulting in Aidan kicking her with his vampire strength and putting Erin in the hospital. This results in her pressuring Josh into choosing between his friendship with Aidan and his relationship with her.
- Though it is shown that even before Erin moves in that she is hostile towards Aidan because of him killing Connor in front of her, his behavior because of not being able to feed because of the virus, and the knowledge that he has a past with killing and has the tendency to still do so because of being a vampire. These reasons cause her to consider killing Aidan when Liam threatens her and Josh if they didn't kill him. She also didn't like him getting Josh involved when helping him with his vampire problems as she wanted Josh to have a normal life now that he was human. Then also she felt protective of Erin and refused to believe that Erin poisoned him as Erin didn't recently show any hostility towards him and she was in a Mama Bear rage about him putting her in the hospital and her general distrust of him to think clearly.
- Nora becoming a jerkass actually got started after she became a werewolf and her overall behavior seems to have come from dealing with that and in Season 3 she was also dealing with the guilt of killing Brynn in self defense.
- Took a Level in Kindness: Her animosity against Aidan ends after he takes the blame for Brynn's death and seemed to be dying from the virus. After he survives the virus she is more kinder to him and even starts approving of his relationship with Kat, when earlier she wanted him to stay away from her. She also ends up with a more positive attitude after meeting the werewolf Pete and getting engaged to Josh.

- Jerkass: Wasn't very nice to Sally when she was alive, killed her, and when she tries to haunt him he taunts her about it
- Took a Level in Badass: He picked up on a lot of ghost tricks more quickly than Sally did after he died. He says this was due to him dying in prison. It doesn't help him.
- The Sociopath: How in the hell did he get engaged to Sally in the first place? Well until the reveal and his breakdown from being haunted by Sally, it seemed like he was a loving fiancé and a nice guy who is grieving the death of his fiancée.

- He also hates it when people call him a Bubble Boy.
- Came Back Wrong: Because he was vamped with cursed werewolf blood, Kenny came back as an extra hungry, extra disgusting vampire.

- Evil Mentor: Used to be this for Aidan.
- Broken Pedestal: Aidan "honored" and "feared" him for over 200 years, but ends up wanting nothing to do with him.
- Fantastic Racism: Like most vampires, he considers werewolves "lesser beings" and looks at humans as pawns.

- Non Human Lover Reveal: The episode "Dog Eat Dog" revealed that Bishop was once very much in love with a human nurse.
- Off with His Head!: Aidan decapitates him with barbed wire.
- Parental Substitute: His relationships with Aidan and Marcus as their sire is played up as a paternal dynamic.
- Super Supremacist: He has little regard for humans, and believes that vampires are superior beings who should subjugate human society.
- Portrayed By: Kyle Schmid
A headstrong vampire that was created by Aidan.
- Ambition Is Evil: What drives Henry. Even after an 80 year exile he desires power and status.
- Chronic Back Stabbing Disorder: He and Aidan have a tendency to screw each other over, and then save each other.
- Emergency Transformation: Aidan turned him after Henry was mortally wounded trying to defend Aidan from a soldier who tried to stake him.
- Fantastic Racism: Downplayed. He does refer to werewolves as "dogs" at one point, but he also alludes to considering them kindred spirits to vampires, during a confrontation with Josh. Like most vampires, he still views humans as weak and "pathetic".
- Flayed Alive: As retribution by Suren.
- From Nobody to Nightmare: As a human, Henry was rather timid and tame, if expressing curiosity and desire to experience being a soldier and killing. As a vampire, he's cocky, bold, and perfectly willing to act on his ambitions and killer instincts.
- Come season 3... he's glamoured a human girl into being complacent with being imprisoned so that he has a supply of untainted blood to survive on.
- Handsome Lech
- HeelFace Revolving Door: As part of his chronic back stabbing disorder.
- HeelFace Turn: He ends up staying on Aidan's side for good in his last appearances.
- Hypnotic Eyes: Standard for vampires, but Aidan often had Henry do it for him because Aidan himself is terrible at it.
- I Hate You, Vampire Dad: Zig Zagged. He and Aidan started out being close for over a decade before falling out and not seeing eachother for 80 years. When they meet again in the present, Henry tries to kill Aidan, causing Aidan to almost kill Henry, before he relents and they make peace. Also, their falling outs are due to Henry's lust for power, not being transformed into a vampire.
- Killed Offscreen: He is last seen in the final stages of the plague, before leaving to die alone. He is not seen again, outside of a flashback and hallucination.
- Living Forever Is Awesome: He unambiguously enjoys being a vampire, in his own words, "When you turned me, you never warned me how much I'd enioy myself."
- The Medic: Before he was turned.
- Normally, I Would Be Dead Now: Henry is harder to kill than a cockroach. He served in World War One, was a fugitive from the vampire world for eighty years, got skinned, extricated himself from a meat hook, and when the plague came around, he still wouldn't die. The plague eventually does him in, though.
- Portrayed By: Vincent LeClerc
Bishop's power-hungry right-hand man.
- Accuser of the Brethren: To a lesser degree than Bishop, due to his jealously/dislike of Aidan; having Aidan back in the Family would threaten his status/position, but he does want Aidan to have a FaceHeel Turn, and come back to their side again.
- Adaptational Badass: Is portrayed more seriously, and less of a Butt-Monkey than his counterpart on the original show; Seth. Seth is easily manhandled twice on the original show by Mitchell (Aidan's counterpart) without fighting back, while Marcus fights Aidan twice, to a draw, and would have killed Aidan, if Rebecca didn't stake him from behind.
- Beard of Evil
- Cain and Abel: With Aidan. However in the 4th season with Sally having altered the events of the show Marcus and Aidan are shown to be on excellent terms as they laugh and get drunk on blood together. Marcus even remarks this "So good to see the Aidan I know and love is back".
- The Dragon: To Bishop
- Driven by Envy
- Evil Minion
- Evil Redhead
- Fantastic Racism: He would've murdered Josh simply for being a werewolf if Aidan hadn't intervened. He also constantly refers to Josh as "dog(gy)" and mocks Aidan for being friends with Josh, only because Josh is a werewolf.
- Killed Off for Real: He gets staked by Rebecca in order to save Aidan, and as revenge for him framing Bernie for the murder of the two boys.
- Related in the Adaptation: Possibly. In the original series Seth (his counterpart) is never explicitly stated to be sired by Herrick (Bishop's counterpart), and therefore, Mitchell's (Aidan's counterpart) vampire sibling. In this series, he is explicitly stated to have been sired by Bishop.
- Removing the Rival: Attempts to at the end of the 1st season.
- Man of Wealth and Taste: Is almost always seen wearing a two-piece suit.
- Super Loser
- The Starscream: To Bishop. It doesn't end well for him.
- The Unfavorite: Or as Bishop repeatedly refers to him as "the mistake".
- The Rival: Sees Aidan as this.
- Smug Snake
- Undying Loyalty: To Bishop. Even though Bishop refers to Marcus as a "mistake" in public and treats Aidan with favourtism as he tries to dissociate himself from The Family and vampires in general, Marcus will do whatever it takes to be in Bishop's good graces.
- Vitriolic Best Buds: Marcus and Aidan's original relationship seems to have been this before Aidan left and went vegan.
- With Friends Like These...: The scene between Aidan and Marcus in the blood den during "Rewind, Rewind" seems to show that their relationship was more like this originally before Aidan left.
- Would Hurt a Child: Marcus kills a pair of young boys on Bishop's orders.
- We Used to Be Friends: In season 4 its shown that Marcus and Aidan may have actually been friends and got along. Aidan's choice to leave The Family and stop drinking live seemed to have been the cause of the rift in their relationship; hence the animosity in season 1.
- You Never Did That for Me: After Bishop gets mad at Marcus for attacking Emily; Marcus remarks that if it had been Aidan, Bishop would have essentially patted him on the back.

- Buried Alive: Spent 80 years buried as punishment for nearly breaking the Masquerade over Henry's betrayal with a human.
- Clingy Jealous Girl: As shown in the flashbacks but she is shown to have gotten mostly over it.
- The Corrupter: Trying in season 2 to get Aidan to go back to his old ways.

Purebred werewolf twins that offer to fund Josh's research.
- Affably Evil: Brynn. According to Nora when running off with her off-screen, she is much more sadistic.
- And I Must Scream: They describe their human existence like this. Josh is uncomfortable with heightened senses and moods the few days before a full moon, they feel that way every moment they're not wolves.
- Bullying A Vampire: Taunting Aidan was probably not the best move, Connor. Especially since he had a rifle loaded with silver bullets.
- Corrupt the Cutie: They basically do this to Nora.
- Jerkass: Very much so.
- Killed Off for Real: Both of them. Connor was first killed by Aidan and later Nora killed Brynn during the time she ran away with her.
- Morality Chain: Nora suggests that Connor was this to Brynn, not the other way around. Of course, this is a relative chain since Connor's idea of a good time is torturing vampires and hunting them down for fun. One can only imagine what Nora might have seen Brynn do without Connor's influence.

Brynn and Connor's father, who comes to Boston in the third season to try and find out what happened to to his son and daughter.

- Anti-Villain: He wants to avenge the deaths of his children, and exterminate vampires; who are more often than not, vicious and remorseless serial killers. He is still a major antagonist.
- Big Bad: One of season 3's two Big Bads.
- Fantastic Racism: Against vampires. Justified, when one considers the majority of vampires are serial killers who have Fantastic Racism towards werewolves.
- Good Counterpart: To Bishop, kind of. Something of a werewolf supremacist, like Bishop is definitely a vampire supremacist. However, Liam would only hunt vampires and those who cross him, while Bishop hunts humans and wanted to subjugate them.
