List of The Owl House characters

The animated series The Owl House features a number of characters created by Michelle Miles. It follows the story of Luz Noceda, an average fantasy loving girl who finds herself transported to the Boiling Isles. She meets Eda Clawthorne and the diminutive demon King, who is her roommate at the titular Owl House. Together, the three go on fantastic adventures and encounter magical phenomena. Recurring characters include Luz's classmates at Hexside Academy, Willow Park, Gus Porter, and Amity Blight; Eda's older sister Lilith, a great witch in her own right; and Hooty, the living door knocker on the Owl House.

Luz Noceda
Luz Noceda (voiced by Alanna Ubach) is a 14-year-old Afro-Dominican-American girl from Gravesfield, Connecticut who ends up on the Boiling Isles, and becomes both Eda's apprentice and a new exchange student at Hexside Academy. She often feels as though she does not fit in. Luz loves all things fantasy and magical, wanting to become a witch. She finds out that she can use magic by drawing glyphs that she sees within her environment and spell circles witches cast to do magic. She finally became an official student of Hexside, though she was saddened at first as she was only allowed to learn one type of magic at a time, and not combine different magic types. Later however, Luz, with the help of the detention track students, saves the school from a magic eating Greater Basilisk who had disguised herself as the Emperor's Coven inspector. Principal Bump was convinced that mixing magics is not a bad thing, and therefore let the other trouble making students take more than one class, with Luz becoming the first student who is officially allowed to learn magic from all the tracks. At the end of the first season, Luz is forced to destroy her only way home to protect it from being invaded by Emperor Belos.

In season two, Luz begins teaching Eda and Lilith to use glyph magic as she searches for a way home. Unbeknownst to her, there is a doppelgänger posing as her while living with an oblivious Camila. She later learns that she is a basilisk named Vee and allows her to stay with Camila who also learns about Luz's predicament. She also begins to realize that she has feelings for her former rival Amity Blight, with the two of them becoming a couple in "Knock, Knock, Knockin' on Hooty's Door". Luz eventually uses a portal to see her mother; during which she discovers that an opportunistic, yet kind basilisk named Vee was posing as her. After convincing her mother to look after her, Luz accidentally gives the impression that she wanted to get away from her and watches helplessly as she is forced back to the Boiling Isles; promising that she will be back and stay. Luz eventually tells Eda and King but neglects to bring this up to anyone else until Amity finds her cell phone and asks her what is happening with her. In "Reaching Out", it is revealed that her father passed away when she was young and she annually collects flowers to remember him. Luz later enacts a plan to help disrupt the Day of Unity that involves allowing herself to be captured by Kikimora that involved Gus using his illusion to have her pose as Hunter. Luz manages to stop the Day of Unity, but in the process is forced to leave King and Eda behind in the magic realm and returns to the human realm with Amity, Gus, Willow and Hunter where she reunites with her mother.

Eda Clawthorne
Edalyn "Eda" Clawthorne (voiced by Wendie Malick as an adult, Dee Bradley Baker in owl beast form, Natalie Palamides as a young girl), also known as "The Owl Lady", is the 40-something, self-proclaimed most powerful witch on the Boiling Isles, and Luz's mentor. A reward has been offered for her capture, due to her criminal record that includes offenses such as selling human items, not joining a coven, and theft. Whilst Eda's approach to teaching is often chaotic and uncoordinated, she has a deeper understanding of magic than she lets on, is able to effectively perform powerful spells, and her approach is ultimately instrumental in Luz discovering her own magic. Eda attended Hexside Academy of Magic and Demonics when she was younger, but now happily despises the school. Whilst she is pleased to see Luz banned from campus following an incident, she relents upon realizing that Luz wants more knowledge, and makes a deal with Principal Bump to allow Luz to attend classes, admitting that she cares about Luz and wants to make her happy.

Eda initially claims she was called The Owl Lady because of her home and possessing traits similar to owls, but it is later revealed to be due to a curse that causes her to turn into an owl beast, and she must drink an elixir daily to suppress the curse. Over the course of Season One the elixir begins to lose its potency on her, and it becomes progressively harder for her to keep the transformation at bay. Eda's relationship with her sister Lilith is complicated. While they clearly care about one another, Eda is resistant to wanting to work with her under the Emperor's Coven and openly fights with Lilith to retain her freedom. It is later revealed that Eda, in fact, wanted to join the coven, but was willing to give it up once she saw that Lilith wanted it. Ironically, it is revealed that Eda was cursed by Lilith when they fought for the position and she had been working to try and break the curse. The sisters make up as Eda's condition worsens, and Lilith decides to share the burden of Eda's curse, lessening its effects but greatly weakening both their magic in the process, and giving them both two different colored eyes.

In season two, Eda begins to deal with the fact that she is no longer all-powerful and initially struggles to earn money for the Owl House. With Luz's help, they manage to secure Selkigris (essentially golden vomit) and are fiscally secure. In "Echoes of the Past", it is revealed that Eda found King when he was just a baby, took him in and practically raised him. Eda was the one who convinced King that he was the King of Demons, although that was unintentional on her part. In "Keeping up A-fear-ances", she is reunited with her mother Gwendolyn and makes amends after making her realize that she has been using holistic medicine to hide her shame of her curse. She is also reunited with fellow witch Raine Whispers, for whom she is implied to have feelings. In "Knock, Knock, Knockin' on Hooty's Door", Eda comes to the realization that her fear of her curse has caused her to push those close to her away. Confronting her owl-beast side in her dreams, she makes a truce with it, and gains the ability to transform into a harpy-like owl-creature. When the Day of Unity arrives, Eda allows herself to be branded with a Bard sigil by the rebel group C.A.T.T.S. so that she can sneak in and disrupt the ceremony. When the plan fails, Raine pulls off Eda's sigil-branded arm so that she would not be subjected to the spell.

King
King Clawthorne (voiced by Frank Welker) is a small 8-year-old Titan with a skull-like head and Eda's roommate who is the self-proclaimed "King of Demons". While it is not known if he truly is the King of Demons, he certainly retains an overly confident and domineering attitude that implies that he once held some greatness. He was initially frightened of Luz when he first met her, but warmed up to her appearance when she helped him. While she continues to coddle him, King wants to be seen as "cool" and claims to have vast knowledge of all monsters and demons, though some of it might be based on his own false presumptions. Regardless, he is willing to acknowledge it if it was incorrect. His relationship with Eda ranges from two casual roommates to a child and his mother. While he is quick to poke fun at her, he cares about her and wanted to help repress her curse. King is shown to be bossy and manipulative, but ultimately shows his heroic and caring side whenever he and his friends are in danger. His ultimate goal is to obtain followers and have absolute power. This results in him finding himself in ludicrous situations such as bringing dolls to life to do his bidding, becoming a teacher at Hexside, and using Eda in her monster form to rule a playground. All efforts usually result in him losing this "power" and things going back to normal. Despite his rambunctious nature, he begins to act more dog-like around Luz and openly misses her whenever she goes out to Hexside or hangs out with someone other than him.

In season two, King's origins begin to be revealed. In the episode "Echoes of the Past", King is revealed to not actually have been the king of demons. He was an infant found by Eda and playfully convinced him that he ruled over all. He discovered that he had just hatched from his egg and was supposed to be watched over by a strange amorphous creature that Eda managed to evade. Believing that his father was someone important, he has Luz reattach his horn to his head with glue so that he can retain as much of his memories as he can look for his father. In "Eda's Requiem", he legally gets adopted by Eda and changes his name to King Clawthorne. In "Knock, Knock, Knockin' on Hooty's Door", King discovers that he can produce an echo blast after admitting that he is upset about his father leaving him. In "Edge of the World", it is revealed that King himself is a Titan. This news affects him emotionally and he begins to question his goals. It is only through a meeting with former Coven Guard Steve that he begins to accept himself. King ends up stopping the Day of Unity by releasing the Collector, learning his father sealed the being away. King then sends Luz and her friends away to the human realm to protect them from the Collector.

Hooty
Hooty (voiced by Frank Welker) is the witty house demon (as he is classified by Patch in "Hooty's Moving Hassle" and in "Agony of a Witch" by Lilith) of the titular house. Themed after a barn owl (with giant legs that he can walk around with when given the power to, à la Baba Yaga's hut), he uses the owl-headed doorknocker to interact with the world around him by stretching his neck to allegedly infinite lengths; he tends to act surreal, awkward, and/or annoying, though this often results in comedic moments for the audience to view. Often, his odd behavior happens when no one is in the house. Despite all this, he is fully capable of taking care of himself as he can reliably attack with his neck. Hooty sometimes has a habit of wanting to be seen as enigmatic or mysterious. He does this by trying to pose riddles to people including Eda, but this usually results in him getting injured. Apparently, he feels everything affecting the house itself and at one point, his door was ripped off, causing him to become unconscious, complete with x eyes. However, by the end of the episode, he is returned and fully conscious.

In season two, Hooty begins to warm up to Lilith (In "Separate Tides", the first episode of season two, she initially referred to him as a "Bird worm") and aims to become her friend. He manages to earn her respect when he helps her secure fire bee honey (though he gets stung in the process) and begins to affectionately call her Lulu while she calls him "Hootcifer" (a play on Lucifer). In "Echoes of the Past", Hooty is revealed to have the ability to remove himself from the door and reinsert himself into other objects. The process of him physically doing this is not shown, but it is enough to disgust Luz, Lilith, and King. Hooty later becomes distraught when Lilith decides to leave the Owl House. However, he becomes a more supportive figure in his friends' lives as he manages to help King, Eda, and Luz embrace their fears and move forward. During his time with King, Hooty stated that he is under the Bug Demon classification. In "Follies at the Coven Day Parade", it is revealed that he is capable of removing his skin to reveal his skeleton.

Willow Park
Willow Park (voiced by Lauren Tom) is a student at Hexside and Luz and Gus's friend who is skilled with plant magic. Originally, Willow was placed in the Abomination Track due to her parents' wishes. She was terrible at performing on this track, which caused much bullying from her classmates, especially Amity Blight, who would call her "Half-a-Witch Willow". Upon meeting Luz for the first time, the two attempted to improve her image, which works up to a certain point. Eventually, Willow was forced to use her plant magic to save Luz, which upon being viewed by Principal Bump, allowed her to transfer to the Plant Track. Since then, Willow has grown from a shy and insecure girl to a confident and even level-headed individual who tends to act as the voice of reason to Luz's eccentricity and Gus' over-confidence. It's revealed that she and Amity used to be close friends since childhood, but due to Amity's parents not wanting to associate with her due to her lack of magic, Amity cut ties with her, causing great misery to both her and Amity. Willow eventually learns this in "Understanding Willow" and, while she still does not reaccept Amity's friendship, she appreciates that she is trying to do right by her. In that same episode, Willow is shown to have two dads named Gilbert and Harvey Park. In "Wing It Like Witches", Willow's newfound confidence has earned her some respect at Hexside, though some students like Boscha still pick on her. She shows considerable restraint, as while she wanted to use the Green Thumb Gauntlet to expand her plant abilities, she immediately returned it uttering "I just wanted to try it out," though she still used it later to help Luz.

In season two, Willow is nearly expelled, an event that shocks her fathers. While Harvey is shown to be very protective and studious, Gilbert secretly allows her to escape to help her friends. In "Hunting Palismen", Willow gets her own staff and palisman in the form of a bee named Clover. In "Any Sport in a Storm", she starts a Flying Derby team with Gus, Skara, Viney and an incognito Hunter. Despite the latter's betrayal, he reforms and rescues his friends, as Willow becomes more appreciative of him. In "Labyrinth Runners", Willow finally makes amends with Amity. At the end of "King's Tide", Willow flees to the human realm with Luz and is currently stranded there.

Gus Porter
Augustus "Gus" Porter (voiced by Phil LaMarr) is a student at Hexside and Luz and Willow's friend who is skilled in illusion magic and is part of the Illusion Track. He has an obsession with human culture and was amazed when he first met Luz. Completely oblivious to common human norms, such as high fiving and even nicknames, he quickly took to being called Gus for short after Luz told him that she knew someone with a similar name. Since then, Gus has been a prominent friend to Luz, usually taking part in many of the magical shenanigans that they get caught up in. He is well gifted in illusion casting, to the point that he freely moves about the campus while his illusion clone sits in for classes. He was moved up a couple of grades, explaining why he is noticeably younger than Luz and Willow. He was the president of the Human Appreciation Society (H.A.S.), but in a misled effort to retain his title, he lied to Luz about having lifted her ban from the school; leading to them getting into more trouble. He ultimately comes clean, but loses his place as president of H.A.S. Gus is self-assertive, but also looking for the approval of others. Nevertheless, he is very confident and does not seem afraid of speaking his mind on things. When using the oracle sphere to show his "best self", his illusion clone informs him that he is "always [his] best self", news that causes him to weep in satisfaction. His father Perry is a news reporter for BBN-HXN.

In season two, Gus is shown to have slightly aged, which according to him is "witch puberty". He also begins to hone his illusion abilities when he aids an illusion master named Braxas. In "Hunting Palismen", Gus gets his own staff and palisman in the form of a blue chameleon creature. Gus joins Willow's Flying Derby team and befriends Hunter, despite his attempt to betray them. In "Labyrinth Runners", Gus is shown to have had trouble making friends as everyone takes advantage of his intellect. Willow became the first true friend he made and taught him how to breath. His illusionary abilities are also revealed to be rather powerful, but can become untamed if he is stressed or upset about something. He befriends Hunter who becomes another genuine friend. At the end of "King's Tide", Gus escapes the Collector, fleeing to the human realm with Luz, but is now stranded there.

Amity Blight
Amity Blight (voiced by E.G. Daily) is a top student at Hexside and an abomination expert who also works part-time at the Bonesborough Library. Upon first meeting, Amity appears to be a snooty, entitled, hypocritical, haughty, selfish, and cold-hearted person who bullies, demeans and looks down on those she feels are inferior to her, such as her former friend Willow. She is finally put in her place when Luz arrives and her presence unintentionally makes her lose her cool in front of her teacher and Principal Bump and loses her top student title when she nearly gets Luz killed, effectively wounding her pride. In her next appearance, she began to hold severe disdain towards Luz, blaming her for getting her in trouble, mocks her dream of becoming a witch and hurts King's feelings, this leads to Luz impetuously challenge her to a witches' duel which will determine whether Luz should continue witch training. However, when Amity is exposed to accidental cheating on Lilith Clawthorne's part, she runs off embarrassed and lashes out at Luz, accusing her for supposedly humiliating her in front of the emperor's coven and for embarrassing her at school, while lamenting how much pressure she puts on herself to be the best, but she is surprised to see that Luz shows kindness while trying to comfort her and allows her to continue magic training. Amity slowly begins to show a sentimental side, even though she still acts hostile towards her, she claims that she's trying to understand Luz (albeit without actually trying to talk to her, listen to her perspective, or admit her own faults and take responsibility for her actions) and is revealed to constantly get picked on by her older siblings Emira and Edric. Eventually, despite her consistent rudeness and disrespect toward Luz, Amity starts to become fascinated with her desire to be friends, and after a night of peril with her at the library, they make up and bond over their shared love of The Good Witch Azura, this leads Amity to finally realize that Luz never meant any harm and never actually took the time to get to know her as a person, realizing her own horrible attitude wasn't helping, thus deciding to reflect on her earlier harmful, hurtful and antagonistic behavior. From that point on, Amity's personality changes from slight indifference, to genuine friendliness, yet displays nervousness when wanting to talk to Luz. Also thanks to Luz's support, she even begins making up with Willow, admitting that her distancing was due to her parents' influence and not being good enough to stand up for herself and promises to stop bullying her and letting Boscha's gang pick on her to make up for all the harm she's done, allowing the two of them to start rebuilding their friendship. Amity is later revealed to have a crush on Luz, to the point that she now gets nervous whenever she gets close to her.

In season two, Amity is more welcoming to Luz and her friends and appears more in control of her emotions around her. However, she is put upon by her parents when they expel them from Hexside for being a "bad influence" on her. But when they put Luz in danger when she tries to get her and her friends back into school, she finally confronts her parents and gets them back into Hexside. She acknowledges that Luz's arrival changed her for the better and redyes her hair lilac because her former green dyed hair was mostly liked by her mother. She also confirms her feelings for Luz by kissing her on the cheek, though she is later embarrassed by this. In "Knock, Knock, Knockin' on Hooty's Door", the two of them officially become a couple. In "Eclipse Lake" they begin to call each other "girlfriends" at the time when Amity helps Eda and King look for the Titan's Blood needed to help Luz return to the human realm and now has her own Palisman and staff which she made herself that is in a form of a cat she named Ghost. In "Reaching Out", she finally tells her father that her joining the Emperor's Coven was Odalia's dream and was never what Amity actually wanted, she doesn't want to join any coven and that she is dating Luz. In "Labyrinth Runners", Amity finally accepts Willow's new stance in life, and later disowns her mother in "Clouds on the Horizon" after learning that she is in on Belos' Day of Unity plans. At the end of "King's Tide", Amity flees to the human realm with Luz, but the destruction of the portal has cut off her way home.

Hieronymus Bump
Hieronymus Bump (voiced by Bumper Robinson) is the principal of Hexside School of Magic and Demonics who wears a demon-shaped hat over half his face. At first glance, he seems rather imposing and possibly sinister. However, he is simply pressed upon by his job as the school principal about his work. He is also seen to be quite reasonable when it comes to changing his mind, and ultimately is open minded despite occasional stubbornness and morally questionable actions, like when he tried to dissect Luz for trespassing while masquerading as an abomination. In light of Luz being at the school posing as an Abomination, Principal Bump had enlisted trouble-smelling creatures to act as the school's security staff where they were thrown in the detention room where the worms inside trap the students in correctional crystals and brainwash them into behaving better. He has a terse relationship with Eda Clawthorne, whom he has kept a notorious record of during her time at Hexside. The only reason why Bump allowed Luz to attend is because he gleefully roped Eda into cleaning up all the messes she made while she was at Hexside. Bump agreed with Eda to keep quiet to the Emperor's Coven of their deal. In "Adventures in the Elements," it was revealed that he was the young student responsible in defeating the opposing school, and helped build Hexside, as shown in its information pamphlet. In "The First Day", Principal Bump is shown to place the students in a classroom after discontinuing the Choosy Hat, as it kept eating the students. Any students that he catches trying to learn something other than their assigned magic get reassigned to the Detention Track. At the end of the episode however, he became more accepting of the other students' desire to learn more than one magic type after Luz and her new friends, the Detention Track Students, saved the school from a deadly Greater Basilisk, who tried to consume all the magic from the staff and students, thanks to their mixed magic skills. Since that day, he made it official that students now have the choice to learn more than one magic type. When Emperor Belos announced his intent to have Eda face the irreversible petrification, Bump was among the people who voiced his disapproval, claiming that she helped him regain his love of teaching after she left Hexside.

In season two, it is shown that Bump openly enjoys Luz's presence at the school but is forced by the Blights, who are a powerful family, to have her, Gus, and Willow expelled. Contrary to them, Bump is severely saddened by this. When the kids attempt to get back into school, it brings him no joy to prevent them from entering. It is shown in the kids third attempt to get inside the school that he thought that life was so dull without them. In "Hunting Palismen" it is revealed that the devil "hat" on his head is actually his palisman named Frewin, which allows him to see, due to some undefined incident in his youth. When Frewin isn't on his head, Bump is shown to have long, black hair, a scar on his right eye, and closed left eye. In "Them's The Breaks Kid", it is shown that Bump used to be Hexside's vice-principal where he worked under the more heinous principal Faust. They clashed with their ideals on their students. When Adrian Graye and the Emperor's Coven raid Hexside to force all the students into joining the Emperor's Coven, Bump is among the teachers and students that take refuge in the Healing Track's homeroom. After the students defeat Graye and the Emperor's Coven, Bump gets them to leave by stating that he would tell Emperor Belos that they were defeated by children.

Lilith Clawthorne
Lilith Clawthorne (voiced by Erin Fitzgerald as an adult, Debi Derryberry as a teen, Dee Bradley Baker in owl beast form) is Eda's estranged older sister and, until the events of the episode "Young Blood, Old Souls", leader of the Emperor's Coven. Lilith and Eda have a strained relationship, with the former insisting on coming with her to see Emperor Belos. She gets humiliated time and time again by Eda, who stymies her at every turn. It was greatly implied that she had genuinely good motives for wanting to have Eda come with her when she unknowingly admits to Luz that Eda wanted to join the Emperor's Coven when she was little. Despite their tense relationship, the two of them do express longing for some kind of reconnection. In "Agony of a Witch", it is revealed that she is the one who cursed Eda to turn into the owl monster when they were young, as she was envious of her magical talent and immeasurable power. This led to Lilith's deal with Emperor Belos after she felt guilty for what she did to her sister. Following Luz's duel with Emperor Belos, Lilith betrays the Emperor to help Luz and uses her magic to split the curse with Eda, resulting in the two of them getting matching split colored eyes.

In season two, Lilith begins living in the Owl House and has been trying to make amends with her sister. She creates a spell that will allow them to spy into the Emperor's Coven and in the process ends up befriending Hooty, whom she affectionately begins calling "Hootcifer". When she makes a special window to spy on Emperor Belos, Lilith is unaware that Belos has sensed this new window. In "Keeping up A-fear-ances", Lilith is revealed to have been ignored by her mother, Gwendolyn, for most of her life. Upon her realizing this, they make amends. Lilith decides to leave the Owl House and move back in with her parents. Later, it is shown that she got a job as the assistant curator at the Supernatural Museum of History. She also tries to take on a more confident attitude to be like Eda and impress Luz, with whom she now shares an aunt-niece relationship. She later returns to the Owl House upon receiving word of the Day of Unity's true results and is now working with her sister and friends to prevent it. In "O Titan, Where Art Thou", Lilith is shown to be very clingy and overly devoted to the point that she disregards other people's feelings. Upon seeing how organized everyone else is within the Emperor's Coven, particularly those who are against it, she begins to realize that she may not have been good at her job.

Hunter
Hunter (voiced by Max Casella) is an arrogant and difficult-to-get along with masked teen who was the current Golden Guard, taken in by Belos as his nephew and enforcer. In reality, Hunter is the latest in a series of Grimwalker clones that Belos created in the image of his brother whom he is implied to have killed for falling in love with a witch. While easygoing and practical despite being imposing and mischievous, Hunter is prodigy in magic who became head of the Emperor's Coven after Lilith defected. Hunter later visits Blight Industries to purchase all the Abomitons for Belos' army as he states that Belos dislikes anyone establishing an unauthorized private army.

In "Hunting Palismen", Hunter developed an interest in wild magic and assume it could cure Belos despite his insistence that wild magic is what caused their family's downfall. He ends up amicably working with Luz after Kikimora tries to kill him when he is sent to gather palismen. While desperate to seek Belos' approval, he is ultimately won over by Luz into doing the right thing, and lets Luz leave with the palismen. Afterwards, Hunter gets a palisman resembling a cardinal and his own staff after risking his job for them. While still devoted to Belos to an almost obsessive degree, he does show genuine gratitude and compassion, implying that he is softening due to his palisman. He attempts to force Willow and her Flying Derby team to join the Emperor's Coven to prove himself to Darius. Upon realizing that what he is doing is wrong, he rescues them and ends up earning his respect. Upon finding out, Darius tells Hunter that he is proud that he has made friends his age. Afterwards, he starts to act as Luz's (unwilling) informant within the Emperor's Coven. In "Hollow Mind", Hunter is accidentally transported into Belos' mindscape along with Luz, resulting in him seeing his "uncle"'s true colors first-hand. Despite his initial denial and justification of Belos' real nature and horrible actions, Hunter's devotion to Belos is completely shattered upon learning his true origin along with the truth behind Belos' goals. Hunter flees for his life soon after in fear that Belos would kill him like his predecessors over defying him, taking refuge in Hexside where he forms an unlikely friendship with Gus while telling truth behind the Day of Unity to the student and facility. At the end of "King's Tide", Hunter is stranded the human realm with Luz, Amity, Willow and Gus.

Emperor Belos
Emperor Belos (voiced by Neil Ross) is a mysterious and sinister masked man who is the ruler of the Boiling Isles and the most powerful magic user alive, whom the Emperor's Coven serve personally. The second season reveals he was originally Philip Wittebane (voiced by Tim Curry), a human witch hunter who entered the Boiling Isles centuries prior to the series and wrote his experiences in a journal. Luz acquired an echo mouse that ate the contents of Philip's journal, allowing her to find clues to return to her world. In "Eclipse Lake", one of Philip's entries reveals that he came to the demon realm via a pool of Titan's Blood within the caves of the Knee. Creating the identity of Belos, he took over the Boiling Isles while using propaganda to ban "wild magic", and establish a system for magic users to use their magic "the right way". This led to him establishing different Covens, where those who don't join are sentenced to irreversible petrification. Belos initially used technology as means to utilize magic while prolonging his life by feeding on Palismens, granting him power while using mental effort to retain his human appearance. Belos concealed his ailment by claiming it as a curse produced from wild magic. His goal is to invoke the Day of Unity, a convergence of the human and demon worlds that would purge wild magic through the current Coven heads he selected, although its true purpose is draining all magic from the Boiling Isles, killing every witch and demon in the process and, in his eyes, 'saving humanity from evil'.

Belos convinced Lilith to join the Emperor's Coven by offering to cure Eda, only to go back on his word while forcing Luz to give him the portal. Though Luz rigged the portal to be destroyed, Belos repairs it and eventually acquires a vial of Titan's Blood to power the portal. Belos also later purchases an entire army of Abomitons from the Blights to increase his forces for the Day of Unity, Hunter noting that Belos dislikes anyone establishing an unauthorized private army. In "Yesterday's Lie", it is revealed in Vee's flashback that prior to the series premiere, Belos had the Basilisk race resurrected to study their ability to drain magic and personally oversaw the search for those that escaped. In "Follies at the Coven Day Parade", Belos reveals his face to all the denizens of Bonesborough which having Terra relay a message to Luz that they would met again soon and he was looking forward to it. In "Elsewhere and Elsewhen", unaware of Belos's previous identity, Luz and Lilith travel back in time to meet Philip as he found a means to meet the Collector, using them to acquire the relic before Lilith punched him in the face for nearly getting her and Luz killed. In "Hollow Mind", Belos appears in a child-like form before Luz and Hunter when they unintentionally entered his mind, using them to subdue the souls of absorbed palismens before revealing that Hunter is a grimwalker he plans to dispose for "betrayal." Belos also reveals his true identity as Philip to Luz, having orchestrated events to maintain the bootstrap paradox Luz caused from her time travel that allowed him to acquire knowledge of the Day of Unity from the Collector. Belos' plans come to fruition as he reveals he never intended to free the Collector before Luz stops him from returning to the human world by slapping him with sigil in an attempt to force him to cancel the draining spell. However, while affected by the Day of Unity, it only causes Belos to lose control of his body as he mutates into a monstrous palismen creature that nearly kills her and her friends. Belos's body is obliterated when King freed the Collector who deactivated the draining spell. Unbeknownst to everyone, a fragment of Belos ending up in the dilapidated house within the human realm after landing on Hunter.

Kikimora
Kikimora (voiced by Jeannie Elias) is Emperor Belos' personal assistant, a diminutive demon with a hand-motif hairstyle with a condescending demeanor to her peers and subordinates. While cowardly before most confrontations, she is willing to discard her cowardice to remain in Belos' favor and is very protective of her placement and job.

In season two, Kikimora shows more of her ruthless side as she uses her dragon in an attempt to murder Hunter and take credit for his own mission of retrieving palismen. She fails when Hunter works with Luz to free the palismen and escape without Kikimora discovering their identities, but she notes that Hunter has an injury matching the one she inflicted on her attacker. Since then, she has considered Hunter to be her workplace arch-rival and seems hellbent on getting her revenge on him than actually helping Belos; causing her to become somewhat mentally unstable. Concerned for her job and well-being, she briefly teams up with Luz and her friends so that she can escape. Upon hearing that she might acquire a long-coveted promotion, she turns on them. Plant Coven head Terra Snapdragon reveals that she was testing her loyalty and that the promotion was real. However, Kikimora is disappointed to learn that the "promotion" was simply that Belos would allow her to live. Kikimora later dispatched the Emperor's Coven to raid the Owl House after he declared its residents wanted criminals. Kikimora is revealed to have been demoted to delivery girl for Belos at some point, kidnapping who she assumed "Hunter", but actually Luz posing as him through Gus's spell, in the hopes of being promoted to a better position. But after being denied her promotion and learning the truth behind the Day of Unity, Kikimora helps King reach the Collector to get back at Belos.

Odalia Blight
Odalia Blight (voiced by Rachael MacFarlane) is Amity's strict and conservative mother who holds high stands for her, Emira, and Edric, having conditioned Amity into a candidate for the Emperor's Coven while willing to remove anyone she considers a bad influence from her daughter's life. She also runs Blight Industries, which produces abomination-based defense systems that only barely work. She used her position as head of Hexside's parent–creature association to have Luz, Willow and Gus expelled from Hexside, only to be convinced by Alador to change her mind as Amity became a stronger witch because of their friendship. Odalia is later revealed to be well aware of the Day of Unity, willfully helping Belos on the notion that she and her family would be spared. When Alador destroys her factory, Odalia flees.

The Collector
The Collector (voiced by Jason Marsden) is a child-like being of immense power from beyond the stars who was sealed away by King's father within a sphere placed in the In-Between World that separates the human and demon worlds, being responsible for trapping the Owl Beast within the curse scroll that Lilith purchased and establishing a Titan hunting cult as the Grand Huntsman. The Collector taught Belos the spell for the Day of Unity on the condition of being released with Belos as his playmate, apathetic to the deaths that result from it. But when Belos goes back on his word, the Collector has King release him by agreeing to cancel the Day of Unity. Once freed, the Collector obliterates Belos with the intent of playing with everyone on the Boiling Isles while keeping King by his side because they "pinky swore".

 * Boscha (voiced by Wendee Lee) – A three-eyed witch and one of Amity's "friends" who is obsessed with Penstagram. She is part of the Potions Track. The only reason why she and Amity hung out is due to the latter's parents setting them up. She is very condescending and bullies others based on their magical prowess. Boscha is also the Grudgby captain of her school and was unwilling to let others see Willow as an accomplished witch. In "Wing It Like Witches", it is heavily apparent that Amity no longer considers her a friend, having told her to "grow up".

They are troublemakers who are always making fun of her and do not show any real remorse for doing so.

Edric takes being twins seriously while Emira is slightly annoyed by it. Despite their supposed high class status, nobody really cares about them. Just like Amity however, they hate being controlled by their parents and will do anything to pull pranks on them. They are also shown to become much more supportive of Amity and even showed awareness of their sister's attraction to Luz.
