List of iZombie characters

iZombie is an American comic book series created by Chris Roberson and Michael Allred, and published by DC Comics under their Vertigo imprint. The comic follows the story of Gwen Dylan, a zombie with vague memories of her past. Gwen becomes a grave digger to obtain brains to sustain herself. Gwen befriends various other mythical creatures including ghost Ellie Stuart and a were-terrier named Scott. Gwen dates a zombie hunter named Horito.

A television series developed by Rob Thomas and Diane Ruggiero-Wright loosely adapts the comic run. It premiered on The CW on March 17, 2015, and ran for five seasons concluding on August 1, 2019. The series stars Rose McIver as medical examiner Olivia Moore, Malcolm Goodwin as police officer Clive Babineaux, David Anders as criminal and brain-dealer Blaine DeBeers. Multiple characters recurred and were subsequently promoted to series regular including Aly Michalka, Robert Knepper, and Bryce Hodgson.

The following is a list of characters that have appeared in the comic and television series.

Gwen Dylan
Gwendolyn Rose "Gwen" Dylan (née Price) is the series' main protagonist. After rising from her grave as a zombie with scattered memories of her past, Gwen takes up residence in her graveyard's crypt, taking a job as a gravedigger so she could have access to the brains required every 30 days to stave off mindlessness by absorbing residue soul essence (in-doing so inheriting parts of the deceased's thoughts and memories), and befriending a local ghost named Ellie and were-terrier named Scott. Several years after becoming a zombie, Gwen learns she was resurrected by local mummy John Amon, seeking her assistance in preventing the dark god Xitalu from consuming the souls of everyone on Earth. Able to pass as human, Gwen begins dating a monster hunter named Horatio, who is initially unaware of her undead status, while Scott begins dating Gwen's brother Gavin, both unaware of their relation. Ultimately, Amon and Gwen are revealed to have known each other before her death, and she had voluntarily killed herself in order to become a zombie and defeat Xitalu. However, upon Xitalu's arrival, Gwen decides to go against Amon's plan to sacrifice the souls of her town to stave off Xitalu for another few millennia, and instead, recognizing his method of absorbing souls to be identical to her own brain consumption, and that Xitalu is themselves a "cosmic zombie", Gwen absorbs Xitalu's soul, becoming a celestial being larger than the Earth. Bidding her friends and family goodbye, Gwen ascends to the cosmos.

Ellie Stuart
Eleanor "Ellie" Stuart (née Roosevelt) is Gwen's best friend, befriending her shortly after witnessing her crawl from her grave. Named after Eleanor Roosevelt, Ellie died in the 1960s after getting hit by a bus, before returning as a "ghost" or "bodiless oversoul". Ellie subsequently befriends a were-terrier named Scott and local mummy John Amon, the latter of whom teaches her how to possess people. Ellie then uses the ability to begin dating again, forming a polyamorous relationship with the vampire Claire and a revenant known as Francisco, later involving Francisco's ex-girlfriend Tricia.

Scott "Spot"
Scott, referred to by his friends as Spot, is a were-terrier and best friend of Gwen Dylan and Ellie Stuart, the former of whom he is initially in love with. He is later revealed to be bisexual and starts dating Gwen's brother Gavin, ultimately marrying him. After being present at his grandfather Marvin's ("Gramps"') deathbed, Scott inadvertently causes his soul to be bound to a chimpanzee.

Horatio
Horatio is an Asian-American monster hunter working for the Fossor Corporation, whose previous girlfriend Bethany was eaten by zombies. Initially investigating a coven of vampires residing in her town with his mentor Diogenes, Horatio begins to date Gwen initially unaware of her species, while she quickly deduces that he is a monster hunter. Upon being informed by her species by Diogenes and criticized for not being able to immediately recognise her as a zombie, Horatio is initially taken aback, before deciding to continue to date Gwen.

John Amon
John Amon is a mummy who has been alive for thousands of years. Resurrecting Gwen Dylan as a zombie for the purposes of using her abilities to prevent the dark god Xitalu from consuming the souls of everyone on Earth, Amon also seeks to cure his wife Ubasti of her were-jaguar nature, which leaves her confined to leopard form for every day of the year but one.

Claire
Claire is a vampire who turned her sorority into vampires shortly after being turned into a vampire, whom Horatio and Diogenes kill in their pursuit of their subsequently-created coven, led by Nemia. Shortly afterward, Claire is resurrected by Galatea, serving as her lab assistant in preparing for the arrival of Xitalu, before calling a truce with Nemia in order to join their forces together. Claire later forms a polyamorous relationship with ghost Ellie Stuart and revenant Francisco.

Gramps
Marvin, known by Scott as "Gramps", is Scott's estranged grandfather, whose soul Scott inadvertently binds to chimpanzee after being present at his deathbed.

Olivia "Liv" Moore
Olivia "Liv" Moore (portrayed by Rose McIver) is the series' main protagonist. A former medical resident who became a zombie when she attended a boat party that was attacked by people who had just taken a new designer drug called "Utopium" while also consuming the Max Rager energy drink. She was scratched by Blaine while he was in full-on zombie mode.

She now works as an assistant medical examiner for the King County Medical Examiner's Office to have access to the human brains she must frequently consume to maintain her humanity and suppress her hunger. Without feeding, she becomes increasingly less intelligent and would eventually turn into a classic zombie that exhibits no human traits and only hungers for brains.

She experiences flashes of memories from the brains she eats, and temporarily takes on random quirks from her subjects—ranging from a fear of pigeons to a sudden appreciation for art to martial arts skills—and has demonstrated the ability to take a bullet to the chest with little damage. Through her visions, Liv vows to use her powers to bring justice to the victims and help Seattle Police find and apprehend murderers. Even with an available cure, Liv is reluctant to take it due to its side effects and her love for solving murder cases.

When Liv enters so-called "Full-on Zombie Mode" her eyes turn red and her strength is vastly increased. The change is triggered by intense stress or anger (or hunger), and the zombie has very little control over the trigger.

In the third-season finale, the existence of zombies is revealed to the world, and by refusing to tan or dye Liv decides to make her zombie status public.

In the fourth season, she inherits the alias "Renegade", eventually becoming a public figure after smuggling individuals in and out of the city.

Clive Babineaux
Clive Babineaux (portrayed by Malcolm Goodwin) is a Seattle PD detective, newly transferred from vice to homicide when the series starts, who gets Liv's help to solve crimes. Liv and Ravi claim that she is "psychic-ish" to account for her knowledge of victims. With her help, Clive has solved many cases in an incredibly efficient and accurate fashion, hoping one day to be promoted to captain.

In the second season, Clive begins dating FBI agent Dale Bozzio, with whom he investigates the "Chaos Killer" disappearances in addition to his cases with Liv. After Bozzio arrests Major, Liv is forced to tell him she is a zombie and that her "psychic skills" are actually a side effect from eating the brains of the victims. He arranged for Major to be released from prison, but Dale leaves him when he cannot provide her with a suitable reason why.

In the third season, Clive receives his own story arc; as he is galvanized to investigate the murder of a family he was close to, and who were revealed to have become zombies affiliated with Fillmore-Graves. He also reunites with his love interest, Dale Bozzio, confessing to her the truth about zombies shortly before she herself is turned.

In the fourth-season finale, Dale is cured and the two are married. Though Clive states he would rather be Dale's husband than a father, it's implied that their daughter Olivia was made that night. They also adopted a son of Clive's ex-girlfriend who was killed in a suicide bombing in the series finale whom Clive initially thought he fathered since he couldn't have sexual relations with Dale while she was still a zombie. By the end of the series, Clive is the only main character who never becomes a zombie at any point during the series.

Ravi Chakrabarti
Ravi Chakrabarti (portrayed Rahul Kohli) is a medical examiner, Liv's best friend and boss, and Major's eventual roommate. He knows Liv's secret and assists her whenever he can to protect as well as study her, expressing an interest in finding a cure for her condition. He used to work for the Centers for Disease Control and Prevention but was fired for his obsession with preparing for an attack with biological weapons. The character has romantic feelings for Liv's best friend Peyton, whom he dated briefly in the first season.

In the third-season finale, Ravi tests a vaccine for the zombie virus on himself; for which he asks Liv to scratch him. Discussing the character's future, Kohli stated "I love playing the human dynamic, it's what the audience can connect with. However, it's tempting [to want to play a zombie.]"

In the fourth-season premiere it is revealed that the vaccine was not completely effective, and that Ravi suffers from periodic flare-ups during which he temporarily becomes a zombie for a few days before reverting into a human. He also gets back together with Peyton, expressing their love for each other.

Major Lilywhite
Major Lilywhite (portrayed by Robert Buckley) is Liv's ex-fiancé (she had ended their engagement to prevent him from becoming "infected" by her condition). Like Liv, he is a University of Washington alumnus; he is employed as a social worker at the local teen center, Helton Shelter. After several teenagers disappear at the local skate park, Major connects those disappearances to "The Candyman," one of Blaine's utopium dealers, and then to Blaine himself.

Despite being deluded into committing himself to an asylum for a week after multiple confrontations with the "Candyman," he continues his investigation after his release—having gained fresh evidence while inside.

Next, Major connects Blaine to a "charcuterie" that serves as a front for "brain-cuisine," and soon after learns of the zombie epidemic. In the first season's finale, after being discovered and held prisoner, he kills Blaine's zombified staff before being stabbed by Blaine himself. To save Major's life, Liv then turns him into a zombie. She later cures him, after which he tells her he would've preferred to be left to die.

In the second season, he is blackmailed into becoming a zombie hunter for Max Rager, as the company attempts to cover up both their own responsibility for the outbreak, and the existence of zombies themselves. While he is named the "Chaos Killer" by the press, Major secretly defies MR orders, and freezes his targets toward their potential future cure. He eventually reverts to zombie form at the end of the second season, learning that his cure had only been temporary.

After FBI Special Agent Dale Bozzio identifies Major as the "Chaos Killer", Liv is forced to tell Clive about the existence of zombies, to get Major out of prison. But the relief is only short lived, we find, as Vaughn Du Clark has discovered Major's treachery; and has abducted the zombies Major had frozen.

In the third season, Major becomes a pariah in spite of being acquitted at trial. This leads him to seek employment and acceptance with Fillmore-Graves Enterprises. He is next cured again, and is human once more; although he feigns being a zombie so that he can remain with Fillmore-Graves.

Though his ruse is eventually discovered, he volunteers to become a zombie again in the third-season finale, after his peers and his girlfriend Natalie are killed by Harley Johns. This leads to Major's break with humanity, and his siding against them along with Fillmore-Graves in the "New World Order." He later proves his loyalty to them by killing a mob of anti-zombie humans at the company's behest although he seems to take no pleasure in doing so.

By the end of the fourth season, Major becomes Chase's right-hand man and leads a squadron of soldiers composed of teenage zombies. Major briefly rekindles his relationship with Liv until they split again over disagreements with Renegade's operation, calling Liv out for self-righteousness over her belief of the other zombies' lack of morality. He succeeds Chase Graves as the commander of Fillmore-Graves after killing Chase to save Liv. After the United States cease their shipment of brains to New Seattle, Major makes a partnership with Blaine, whom he offers debt relief and a full pardon, offering a chance to become a hero to zombiekind in exchange for supplying brains.

Blaine "DeBeers" McDonough
Blaine McDonough (portrayed by David Anders), commonly known by the pseudonym Blaine DeBeers, is a drug dealer-turned-zombie who dealt a tainted version of the experimental drug, Utopium, which helped cause the zombie outbreak. Blaine was incidentally turned into a zombie by Liv when she threw her Max Rager drink in his face, after he attempted to grope her while high on the Utopium. The chemical mixture of the drink and drug were later confirmed in the second-season finale to be what originated the zombie outbreak. While in full-on zombie mode at the boat party, he scratched her, turning her into a zombie in turn.

Although he comes from a wealthy family, Blaine did not have a happy childhood; his depressed mother committed suicide, his doting grandfather was committed to hospice, and Blaine himself was abused by his nanny. As an adult, his father Angus considers him "a disappointment" after giving him money for failed businesses. According to Angus, he attended Wharton, though did not last a full semester. After some point Angus cut him off financially, leading Blaine to pursue work dealing drugs for Stacey Boss.

In the first season, Blaine initially claimed to Liv that he resorts to grave-robbing to access brains, but in reality he has set up a new "drug ring" whose customers are other zombies and product is the brains of murdered local homeless teens. His base of operations in the first season is a local butcher shop from which he runs a home delivery service of gourmet prepared brain meals for wealthy zombie customers. In keeping with his drug-dealer approach, he has been shown attacking his former criminal associates and rivals, and creating new zombies to drive up demand. It is revealed in the second season that his father was his first client, and Blaine extorted him into bankrolling his endeavors once more.

In the second season, after being cured, he moves his brains business to a funeral home—no longer murdering for his product supply. Desiring to become Seattle's new kingpin; he strong arms his client and district attorney Floyd Baracus to pursue a case against crime lord Stacey Boss, Blaine's former employer. In exchange for his testimonies Blaine receives immunity for his (known) crimes, and grows close to Peyton who was assigned the case. The two sleep together before she learns of his true nature from Liv, after he is accused by Clive and Bozzio of being the Chaos Killer. Not long after, Blaine eventually reverts to a zombie state before injecting himself with another attempt at a cure; after which he becomes an amnesiac.

After this status quo carries into the third season, it is revealed the amnesia was only temporary and that the character feigned memory loss in an attempt to change his life and how people viewed him, in the process finding a fresh start and happiness with Peyton. Shot by one of his father's henchmen, Blaine has a client turn him back into a zombie, and then kidnaps Angus and takes over his business. Despite their relationship returning to it is antagonistic roots, Blaine later helps Liv and Clive in an investigation. With the existence of zombies made public knowledge in the third-season finale, Blaine found himself a somewhat legitimate businessman. Having already stopped killing for his brain supply and intentionally creating more zombies; the zombie outbreak forces him to change his business model. With Fillmore-Graves offering brain tubes to the public, he no longer is able to extort his existing clientele for their food supply. Instead, he capitalizes on the rarity of "whole brains" to draw in a larger client base.

Following this, showrunner Rob Thomas implied about the fourth season: "We keep calling [Blaine] Rick from Casablanca. He is the man who can get things. He is going to profit from this new world. He is going to run the black market. Blaine is going to open a new restaurant. He is going to be doing very well." This holds true as Blaine continues to feed Seattle's zombies during the starvation crisis, and does under the table work for Chase Graves. However, the character largely returns to his villainous roots; being revealed as the thief who stole the zombie cure and killing Floyd Baracus to display it is effectiveness before auctioning it off. Blaine also plans to spread the zombie virus throughout the country, in an effort to gain a monopoly on real estate. He also contests with the return of Angus, who had been driven mad in the well and becomes an evangelical zombie cult leader who wishes to make amends with his son.

In the fourth-season finale, he is given a full pardon by Major and becomes the sole brain provider for New Seattle, with his debts waived and the opportunity to become a hero to zombiekind.

The character has often been compared to Spike from the Buffy the Vampire Slayer mythos. Coincidentally, Anders consulted Spike's portrayer, James Marsters, prior to bleaching his hair for the role. Show co-creator Diane Ruggiero-Wright stated prior to the series finale that there were once plans to redeem the character, who acted as the series’ wild card, but they ultimately fell through.

Peyton Charles
Peyton Charles (portrayed by Aly Michalka) is Liv's best friend and roommate, who expresses concern about Liv's declining interest in life after the boat party. She also works as an assistant district attorney for the King County Prosecuting Attorney's Office. Peyton learns of Liv's secret at the end of the first season, prompting her to leave Seattle.

Peyton returns in the second season, reconciling with Liv and being appointed head of the task force against Utopium. While making a case against crime lord Stacey Boss, she grew close to Blaine and slept with him before learning that he turned Liv into a zombie.

Though a recurring character in the first two seasons, she is promoted to a series regular with the third season, at which point her professional and personal lives are highlighted. Peyton had a relationship with Ravi during the first season, which was briefly rekindled at the end of the second season. After visiting him to clear the air following a disagreement involving Blaine, the two share a kiss, with Peyton realizing Ravi had a one-night stand with Katty Kupps; who was still present in his home. She then initiates a relationship with the seemingly reformed Blaine, which deteriorates upon the revelation he feigned the true duration of his memory loss. She also uncovers a conspiracy that implicates her employer, Floyd Baracus, in a number of suspicious deaths. After he is proven innocent, Peyton accepts a position as his chief of staff.

Teasing her role in the fourth season, Rob Thomas stated: "She'll have her fingers in a couple of pies next season. Half of the prosecutors working in Seattle escaped the city before the wall went up, and Peyton will get called in on occasion to fill in when the case load becomes such that they need an extra hand. Working the mayor's office, she will be on the front line of mediating disputes between zombies and humans. Turns out humans don't want their children going to school with zombies, or sharing restrooms, or sharing city parks. There is a lot of work to be done."

Angus McDonough
Angus McDonough (portrayed by Robert Knepper) is Blaine's estranged and abusive father whom he turned into a zombie, and who tried to force Blaine to work for him prior to becoming one of Major's Chaos Killer victims. After discovering Major's role in his father's disappearance, Blaine negotiated for Angus' return so that he could force him to amend his will. Upon his father's disappearance, Blaine learned Angus added a stipulation that his estate would be left to Blaine's abusive childhood nanny were his death to result from foul play.

In the third season, he is freed by Don E., whom he forms an alliance with in order to get revenge upon his son. Establishing their own brain dealing business, Angus finances the new zombie club, the Scratching Post. Prior to seizing Blaine's client base, Angus commands Don to increase the zombie population in order to attract new and wealthy clients. After he learns the nature of Fillmore-Graves, Angus develops a plan (later adopted and amended by Blaine) to partner with them for "global brain distribution". After Blaine survives a hit Angus orders, the former traps the latter in a well on their family estate and usurps his business. He is later shown to visit him to gloat and bring him brains; lest he become a mindless "Romero" zombie.

After recurring in three episodes each in both the second and third season, it was announced the character would be promoted to the main cast with the fourth season. In regards to the announcement, Rob Thomas stated, "Angus is going to get out of the well, and he is going to be up to no good, and he is going to have some very hardcore pro-zombie people on his side. There's going to be a human terrorist organization that doesn't want any human-zombie fraternization. This is not about one big bad this year. It's coming at our characters from all sides of the spectrum."

When the character returns as a regular in the fourth season, he is freed by a resentful Dino and is revealed to have gone insane during his imprisonment. As such, he believes the words he heard from Blaine while in the well were the words of God, and becomes a religious cult leader known as "Brother Love", preaching pro-zombie/anti-human sentiment.

Though he attempts to make amends with his son, the relationship deteriorates upon Angus learning that Blaine manipulated him. Stating that his son was dead to him, Angus led his cult in an effort to escape the city before ultimately being executed by the United States military.

Don "Don E." Eberhard
'''Donald "Don E." Eberhard''' (portrayed by Bryce Hodgson) is a drug dealer and associate of Blaine who helps him track down boat party Utopium for Ravi's cure, while also assisting him in his professional and criminal endeavors. The character voluntarily becomes a zombie and briefly takes over Blaine's business once he becomes an amnesiac. In the third season, the character briefly abandons Blaine to form an alliance with his father to open the zombies-only club, the Scratching Post, before later reconciling with Blaine himself when the latter usurps the former. Along with Blaine, he is given a full pardon at the end of the fourth season in exchange for supplying New Seattle with brains. Hodgson also portrayed the character's late twin brother, "Scott E." in two episodes of the first season. The character was promoted to the main cast for the fifth and final season.

Though the two manipulate Angus' cult into aiding them, they are unable to obtain the money before Peyton turns it over to Liv to aide in her Renegade activities.
 * Drake Holloway (portrayed by Greg Finley, recurring season 2; guest season 3): Initially presented as a drug dealer acquaintance of Don E. and Blaine, the character becomes Blaine's mole in Mr. Boss' organization.

Towards the end of the fourth season, he is cured and killed by Blaine in an effort to prove the zombie cure's validity to potential bidders on the dark web.

Savage's abrupt departure from the series was a result of her commitment to I'm Sorry, a series which she both created and stars in.

It is because of him that Clive is forced to reveal the existence of zombies to Bozzio, as she captured him receiving a shipment of brains.
 * Jeremy Chu (portrayed by Patrick Gallagher, recurring season 2; guest season 3): A reporter and client of Blaine's. He writes articles at Blaine's behest that result in Baracus assigning Peyton to the Stacey Boss case, and that convince Seattle's then-Mayor to refuse Peyton's resignation.

Though she claimed Oates would fine her wherever she went, after Major gives her a dose of the zombie "cure," she travels the world before returning to Seattle. Reaching out again to him.

 * "Speedy" Pete (portrayed by Paul Anthony, recurring season 2): A former dealer for Stacey Boss who was recruited by Blaine to help establish his own drug empire, and act as a patsy to hide his involvement. Speedy was ordered by Blaine to enlist young men whose finances cut off by their wealthy families; in reality so that said dealers' at the hands of Mr. Boss' henchman gave Floyd Baracus enough cause to pursue a case against him at Blaine's urging.

 * Brody Johnson (portrayed by Justin Prentice, recurring season 2): A college frat-boy whom Liv briefly befriended during a murder investigation.

 * Rob Thomas (portrayed by himself, guest season 2): Playing a fictional version of himself, Thomas initially has a vocal cameo as he is employed by Vaughn Du Clark to write a song for Max Rager's SuperMax commercial.

Thomas' brain was consumed by Vivian Stoll and her Fillmore-Graves mercenaries, and it is mentioned in the third-season premiere that his friend and occasional collaborator Carlos Santana issued a public statement in the wake of his death. Thomas was a fan of the show prior to his appearances, and his inclusion was a reference to the fact he and series creator Rob Thomas are often confused for one another on social media.

Introduced in season three

 * Justin Bell (portrayed by Tongayi Chirisa, recurring season 3; guest seasons 4–5): A zombie Major befriends during his tenure at Fillmore-Graves. Turned into a zombie by Vivian Stoll, he was not initially a soldier within, but a disc jockey who was while working at a Fillmore-Graves gathering. After succumbing to a biological attack, Stoll turned Justin to save his life before offering him a job among her paramilitary group. He eventually becomes a love interest for Liv, although she eventually cheats on him with Chase Graves. Justin breaks up with her when she admits this to him, and he later alerts Fillmore-Graves soldiers to her presence when she attempts to stop them from infecting humans with a false vaccine. He returns in the fourth-season finale and makes amends with Liv, joining Major in the reformed Fillmore-Graves.
 * Harley Johns (portrayed by Andrew Caldwell, season 3): An anti-zombie fanatic who seeks to expose the truth about zombies after his brother was killed at Max Rager.

While she is dating Justin Bell, Liv sleeps with him while under the influence of Ravi's promiscuous former employer, Katty Kupps. In the aftermath she discovers information implicating him in Katty's murder. It is later revealed that while Vivian Stoll with Fillmore-Graves had a contingency plan in place involving a biological attack, it was Carey Gold (along with her daughter Patrice) who was behind Kupps' murder and set the plan in motion without Graves' order. Instead of letting the humans die, Chase instead set about a plan to provide a tainted vaccine that would turn them into zombies. In spite of this he maintains he is not the bad guy, to which Liv retorts that he is holding Seattle hostage for brains from the rest of the country. The character has been shown to have a short temper, and has a tendency of non-fatally shooting zombies (Justin Bell for stealing confiscated Max Rager, and Johnny Frost's producer for refusing to air his follow-up video to Frost's report revealing the revelation of zombies) who displease him. In the fourth season Chase finds himself morally compromised and struggles not to buckle under the pressure of his new position, eventually snapping and killing one of Major's teen soldiers. According to Rob Thomas, the character was conceived as a back-up plan/surrogate for Vivian Stoll after Andrea Savage left the series due to her commitment to I'm Sorry. By the end of the fourth season, in which he buckled under pressure, Major and Liv kill Chase in the fourth-season finale in an attempt to save the latter from execution.
 * Rachel Greenblatt (portrayed by Ella Cannon, recurring seasons 3–4): A photojournalist with whom Ravi strikes a friendship while attending one of Harley Johns' "zombie truther" meetings. Unlike most in attendance, she held no ill will towards zombies and simply wished to capture one on film. After she witnesses Liv and Blaine rescue Don E. from Harley Johns, Ravi tells her the truth about zombies. Though at first it seemed the two would be starting a relationship, she published a picture of Liv alongside all the information that Ravi told her. She later returned to the morgue in an attempt to clear the air between them, but Ravi rejected her; feeling both betrayed and incredulous that she had further questions. She makes a cameo in the fourth season where she is terrorized by Major in retaliation by Fillmore-Graves in response to her writing an article painting Mama Leone a Martyr.
 * Carey Gold (portrayed by Anjali Jay, season 3): A teacher and secretary within Fillmore-Graves and confidante to both Vivian Stoll and Chase Graves. She was ultimately revealed to be behind the deaths of Vivian Stoll and the zombie family with ties to Clive. She was killed by Chase Graves during an attempted mutiny at Fillmore-Graves. While she was behind the biological attack that plagued Seattle, the plan was initially formed as a contingency by Vivian Stoll. Carey simply put the plan into action without Fillmore-Graves order. It was initially believed she was behind the death of Katty Kupps as well, though it was revealed to be her daughter, Patrice. Before her death, Carey warned Chase that she had more rogue soldiers within Fillmore-Graves.
 * A.K. Fortesan (portrayed by Mike Dopud, season 3): The Fillmore-Graves field commander; and superior officer to Major, Justin, and Zach.

The character was intended to have a relation to Vivian Stoll, though this was never confirmed on-screen.

 * Dino (portrayed by Ryan Jefferson Booth, recurring seasons 3–4): An enforcer initially employed by Angus, and later employed by Don E. and Blaine as a bouncer at the Scratching Post. Dino initially shot Blaine on Angus' order, but apparently spared him a fatal shot when Blaine offered him more money than his father. It is noteworthy however; that while Dino spared Blaine a fatal shot, he did not save his life nor is he responsible for Blaine's reversion to zombie form. Though he claimed to Angus he shot him in the mouth, Dino apparently left him bleeding out; which prompted Blaine to turn to Jeremy Chu to be turned into a zombie once more, so that he would not succumb to his wounds. Though initially positioned as a hitman under Angus' employ, working to obtain brains for high-end clients, it is unknown if he carries out this role once Blaine takes over the Scratching Post. It is never mentioned and the character is mostly seen lounging around the bar, unpacking crates of brains, and overseeing their deliveries. He eventually grows tired of Blaine's orders and frees Angus after being informed of his location. Despite his earlier betrayal, he expects compensation, only to be knocked unconscious for his troubles. When Blaine realizes Dino freed Angus from the well, he orders Don E. to deal with him. After decapitating Dino, Don E. tells an amused Dino that he plans to send his disembodied head to Gwyneth Paltrow.
 * Katty Kupps (portrayed by Christina Cox, season 3): Ravi's promiscuous former employer at the Center for Disease Control. The two had a one-night stand, contributing to his break-up with Peyton. She later returns to investigate a potential bio-terror attack, which leads to her eventual murder, seemingly at the hands of Chase Graves. It is revealed that while the bio-attack was a fail-safe plan Chase had developed, the plan and Kupps' murder were in fact carried out by Carey Gold and her daughter Patrice.
 * Shawna (portrayed by Sarah Jurgens, season 3): A woman who writes to Major after he is outed as the Chaos Killer. The two briefly become a couple, but Major breaks up with her when he learns she shared private photos and messages on social media, something she claims she did to help the public's perception of him. She inadvertently leads to him being fired from Fillmore-Graves, as their intimacy revealed Major's human status to Chase Graves.
 * Tatum Weckler (portrayed by Ava Frye, season 3): A teenage zombie in the care of Carey Gold and who is the best friend of Carey's daughter, Patrice Gold. In the third-season finale, it is revealed that she was turned after joining her friend Patrice at the same Fillmore-Graves party. Liv also discovers it was actually Carey that blackmailed her late father, as a pawn in a conspiracy to ensure the mayoral appointment of a zombie mayor in the ignorant Baracus. She and Patrice are taken into custody by Fillmore-Graves for their involvement in Carey's plans, and the attempted murder of Liv. As the soldiers had their guns trained on the girls, their fates are uncertain; something both actresses have acknowledged while expressing an eagerness to return.
 * Patrice Gold (portrayed by Anisha Cheema, season 3): A teenage zombie who is the daughter of Carey Gold and the best friend of Tatum Weckler. She was turned into a zombie at a Fillmore-Graves Fourth of July party alongside Tatum Weckler and Justin Bell. In the season 3 finale, she is ultimately revealed to be the killer of Katty Kupps and is later taken into custody by Fillmore-Graves soldiers alongside Tatum for both being an accomplice to her mother and the attempted murder of Liv. As the soldiers had their guns trained on the girls, their fates are uncertain (especially as her mother was killed by Chase Graves after staging a coup); something both actresses have acknowledged while expressing an eagerness to return.
 * Wally Reid (portrayed by Mateo Mingo, season 3): A young zombie boy who is murdered at the beginning of the third season, and who is revealed to have been a former neighbor of Clive. Wally became something of a surrogate son to him after he rescued Wally and his mother Anna from their abusive patriarch. Clive lost contact with the two when he went undercover on a vice assignment, and it is revealed they became zombies after moving in with Wally's Uncle who worked for Fillmore-Graves.
 * Mr. Huntsman (portrayed by Peter Kelamis, season 3): A paranoid man who believes in the existence of zombies. He was a neighbor to Wally Reid's family and initially a suspect in their murders after making incriminating calls to Chuck Burd's radio show. Though he provides evidence he was out of town at the time the murders were committed; he later joined Harley Johns' anti-zombie group alongside Billy Cook. The two are eventually killed by Harley after he himself is turned into a zombie.
 * James Weckler (portrayed by Gordon Michael Woolvett, season 3): Father to Tatum Weckler. A small time crook who extorted Johnny Frost and murdered a dominatrix whom he (along with Brandt Stone and Floyd Baracus) frequented. Weckler was later revealed to have been extorted by Carey Gold to destroy any evidence of Baracus' indiscretion, lest he lose his mayoral election. After backing out of a plea deal arranged by Peyton, Weckler was hung by a guard in his cell, making it look like a suicide. The guard was later killed, leading Peyton and Liv to uncover a conspiracy. Initially they believe Baracus personally turned Weckler's daughter to strong arm him, while in reality he was ignorant of the truth: Carey Gold threatened to cut off Tatum's brain supply. Weckler also had a history of mental illness, which included hallucinations of his late wife. After Liv consumes his brain, she herself has a hallucination through which she makes peace with the deceased Drake Holloway.
 * "Vampire" Steve (portrayed by Kett Turton, recurring seasons 3–5): An expert technician within the Seattle Police Department, and a friend to Jimmy Hahn. Though Steve is not truly a vampire, Clive and Liv refer to him as such due to his gothic style and demeanor; which he was revealed to have initially adopted in an effort to impress a woman who was a fan of The Twilight Series. In the fourth season, Steve remained in Seattle after the zombie outbreak.
