Hazbin Hotel and Helluva Boss are two American animated series created, directed, written, and produced by Vivienne "VivziePop" Medrano, animated primarily by SpindleHorse Toons, and set in Hell. Some of the characters of the shows were originally developed for Medrano's cancelled webcomic series ZooPhobia.

Hazbin Hotel focuses on eight characters: Charlie Morningstar, princess of Hell and owner of the Hazbin Hotel, which offers sinners a chance at redemption to enter Heaven; Vaggie, her girlfriend; hotel patrons Angel Dust and Sir Pentious; Alastor, the powerful "Radio Demon" and Charlie's business partner; Husk, the hotel's bartender; Niffty, the hotel's maid; and Adam, the first man and leader of Heaven's exterminator angels ("Exorcists"), who leads an annual Extermination of Hell's sinners.

Helluva Boss initially focuses on five characters: Blitzo, an imp and head of the assassination company I.M.P; Moxxie and Millie, a married imp couple employed at I.M.P; Loona, Blitzo's adopted hellhound daughter; and Stolas, a Goetian prince of Hell, whom Blitzo has an intimate relationship with. The second season further focuses on Fizzarolli, a jester celebrity and Blitzo's childhood friend, and Crimson, a mob boss and Moxxie's father.

Both series also feature numerous supporting characters, each of whom plays a prominent role in a story arc. Included among them are the angels of Heaven, many other sinners and Hellborn demons, the Seven Deadly Sins, and the overlords of Hell.

Charlie Morningstar^[1][2] (voiced by Erika Henningsen^[3]) is the main protagonist and founder of the Hazbin Hotel. She is the daughter of King Lucifer and Queen Lilith, and was born in Hell. Charlie is optimistic and cares deeply for the well-being of her people, which is not taken seriously by the majority of demons in Hell.^[4][5][6] She was confirmed to be bisexual by series creator Vivienne Medrano on her Twitter account.^[7]

Vaggie (voiced by Stephanie Beatriz^[3]) is the lesbian manager of the Hazbin Hotel^[1] and Charlie's girlfriend.^[4][5][6] She is highly supportive of Charlie and has a quick temper, but she often tries to be a level-headed and rational person, and she struggles to keep the hotel's image from being tarnished by Charlie and Angel Dust's antics. Vaggie was once an Exorcist angel, and after sparing a defenseless demon child, she was betrayed by Lute, stripped of her position, and mutilated. She was saved by Charlie, who, initially unaware of her angelic nature, fell in love with her. She was originally a character in the webcomic ZooPhobia as "Vaggie Motha".^[8]

Anthony "Angel Dust" (voiced by Blake Roman^[3]), or simply Angel, is a gay spider demon, an adult entertainer, and the first volunteer for Charlie's rehabilitation program. He does not take Charlie's cause seriously, and often gets into mischief behind her back. He is in a toxic relationship with his abusive boss, Valentino. Despite Angel Dust's insolence, he genuinely cares about his friends and strives to better himself, even if he is not keen on showing his softer side. He was originally a character in the webcomic ZooPhobia.^[9]

Alastor (voiced by Amir Talai^[3]), also known as The Radio Demon, is an eccentric overlord of Hell. He was once a radio broadcaster in the 1930s, and is now a demon with deer-like characteristics. His voice has an effect that imitates radio static, complete with sound effects and theme music. His charming and elegant exterior hides a twisted and sadistic mindset. He offers his powers to Charlie to help her maintain her goal of running the hotel, but only for his own amusement, as he enjoys watching demons struggle to redeem themselves only to fall from grace. He has rivalries with many characters including Vox, Sir Pentious, and Lucifer. In "Dad Beat Dad", it is revealed that he is trapped in a deal with an unknown entity. Alastor is an asexual character.^[10] He was originally a character in the webcomic ZooPhobia.

Husk (voiced by Keith David^[3]), also known as Husker, is an ill-tempered, gambling, alcoholic cat demon. Alastor summons him to serve as the bartender of the hotel in the series pilot. He is a pansexual character. It is revealed in "Masquerade" that he was once an overlord of Hell, but due to his gambling addiction, he was forced to sell his soul to Alastor in order to keep his powers, while losing his status. Despite being an irritable drunk, Husk is shown to be wise and empathetic, especially in his friendship with Angel Dust. He was originally a character in the webcomic ZooPhobia.

Niffty (voiced by Kimiko Glenn^[3]) is a small, hyperactive cyclops demon from the 1950s^[11] who is obsessed with cleanliness and men. She is summoned by Alastor to serve as the hotel's maid in the series pilot. Despite her macabre and often creepy mannerisms, she usually means no harm. However, in "The Show Must Go On", she delivers the killing blow to Adam by stabbing him in the back.

Sir Pentious (voiced by Alex Brightman^[3]) is an anthropomorphic cobra demon from the Victorian era,^[12] and a skillful inventor. He was recruited by Vox to spy on Alastor in the hotel, but was ungraciously fired after being found out. Charlie offers him a second chance, and he chooses to become an official patron at the hotel, touched by Charlie's compassion. He is shown to have feelings for Cherri Bomb. In "The Show Must Go On", Sir Pentious sacrifices himself to stop Adam, and is redeemed and sent to Heaven. He has created several small, sentient eggs, which he refers to as his "Egg Boiz", who serve as his loyal minions.

Adam (voiced by Brightman^[13]) is the first human, a high-ranking angel in Heaven, and the main antagonist of the first season. He commands the Exorcist angels, and by extension the Exterminations of Hell. He is a narcissistic and immature leader who dismisses and mocks Charlie's idea of sinners ascending to Heaven. He is shown to want revenge on Hell for killing one of his Exorcist angels. In "The Show Must Go On", he was killed by Niffty during a battle between Heaven and Hell.

Blitzo (voiced by Brandon Rogers,^[14][15] singing voice by Michael Romeo Ruocco, child voice by Mason Blomberg) is the bombastic and semi-competent imp founder of I.M.P (Immediate Murder Professionals) and the protagonist of Helluva Boss. He has an on-and-off relationship with Stolas, a royal demon of Hell. Blitzo was a circus performer in his youth, but after accidentally causing a fire which resulted in the death of his mother and the disfiguring of his friend Fizzarolli, he left the circus. Trauma caused by the incident led him to suffer from guilt and insecurities, which he hides with his brash outward personality. Despite this hard exterior, he is fundamentally a good man at heart and is shown to deeply care for his employees. He adopted a daughter, a hellhound named Loona. According to his official Instagram account, he is pansexual.^[16]

Moxxie (voiced by Richard Steven Horvitz^[17]) is a neurotic and kindhearted imp who serves as the straight man weapons expert of I.M.P, and is married to Millie. He is easily annoyed by Blitzo's immaturity. He was born into a crime family. After being incarcerated following a heist gone wrong, he met Blitzo and decided to work for him after the two escaped prison. In September 2020, series creator Vivienne Medrano revealed he is bisexual on her Twitter account.^[7]

Millie (voiced by Vivian Nixon^[14]), short for Mildred, is the bubbly and good-natured imp bruiser of I.M.P, and is married to Moxxie. She is an extrovert and is not afraid to speak her mind, whether she's expressing excitement or scolding a coworker. She is also highly protective of Moxxie, often going into a fit of rage if he is in danger.

Loona (voiced by Erica Lindbeck^[18]) is the hellhound receptionist of I.M.P. She generally has no interest in matters going on around her. Loona is rude and apathetic towards her colleagues. She is the adopted daughter of Blitzo, to whom she occasionally shows a softer side.^[19] She struggles with making friends, although she has a crush on a hellhound named Vortex. Loona is a bisexual character.

Stolas (voiced by Bryce Pinkham,^[20] child voice by Leander Lewis) is an owl-like prince of Hell, inspired by Stolas of the Ars Goetia in the Lesser Key of Solomon, in the Ars Goetia circle. He has a complicated relationship with Blitzo. He was unhappily married to Stella, and has a daughter named Octavia, around whom he acts as a "dorky dad", putting her happiness ahead of everything else. He divorced Stella after she discovered his affair with Blitzo. He is a gay character.

Fizzarolli (voiced by Alex Brightman, child voice by Remy Edgerly), or simply Fizz, is a jester-like demon, Asmodeus' boyfriend, a childhood friend of Blitzo, and the brand icon of Mammon. Fizzarolli and Blitzo were close friends in their youth, but after Blitzo caused a fire which disfigured Fizzarolli, the latter resented him. The two eventually made amends after Blitzo apologized to Fizzarolli. He is gay.

Vaggie's character has been received positively, garnering particular attention for the development of her relationship with Charlie, her true motivations during the first season, and for Beatriz's singing performances:^{[42][43][44][45][46]} Animation Magazine summarized Vaggie's character as "tough but [with] a heart of gold".^[47] Screen Rant described Vaggie as "the backbone" and "best character" of Hazbin Hotel, calling her a "realistic and shrewder" character, and her and Charlie "a classic grumpy/happy duo", noting her day-to-day "interactions with the hotel’s staff and residents [as] always hilarious because she doesn't put up with anyone's nonsense",^[42] Comic Book Resources lauding them as "the perfect power couple".^[48] Decider complimented Vaggie's depiction as "a total simp" and her "sentimental and fluffy" moments with Charlie,^[43] while The A.V. Club described her as "com[ing] off as a carbon copy of Lake Bell’s deadpan Poison Ivy in Harley Quinn".^[44] AutoStraddle praised Vaggie and Charlie's relationship as "the devilish heart" of the series, which "had its bumps and bruises throughout the season [without] a big breakup blowout or cheating [with] so many cute little moments [leading to the] last two episodes, where fixing their relationship is almost as important to Charlie as figuring out how to stop the extermination", concluding by lauding the series' "cute little couple-y moments that made [them] squeal with joy,"^[49] and noting Vaggie's "pessimist[ic] surly demeanor".^[50] Telltale TV described the relationship as "your stereotypical 'opposites attract' pairing [with] a lot of unexplored depth", complimenting Beatriz's singing voice, while noting it as "somewhat jarring compared to her speaking voice [though] nailing the vocal intricacies of her predecessor Mónica Franco".^[45] The Illuminerdi called Beatriz "a perfect fit" for the role.^[46]

Collider lauded "Jeremy Jordan's Lucifer [for having] stole[n] every single scene he was in. I did not know what to expect from the King of Hell, but he got the biggest laugh out of me by far [and] my favorite songs of the season."^[51] MXDWN lauded the "emotional scenes" between Lucifer and Charlie as "feel[ing] impactful and real within the story," while praising the "incredible chemistry" between Jordan as Lucifer and Amir Talai as Alastor;^[52] The Review Geek likewise complimenting the "emotional punch [in] Jordan's beautiful voice",^[53] which The Sea Hawk lauded as "utterly tearjerking and beautiful".^[54] Comic Book Resources noted "what makes Lucifer interesting [is] his air of mystery, which later evolves into his complexity [as] a charismatic guy with a few flaws that make the angelic man a little bit more human [in being] an insecure man who wants the best for his daughter, but his fears of being bad push him away," in particular praising Jordan's performance for how "that fear of not being good enough shines on through",^[55] noting him as "one of the most relatable characters in the series because of his everyday struggles",^[56] leaving him "among the most layered characters in Hazbin Hotel", praising his "humorous rivalry with Alastor [as] a highlight of Season 1".^[57] Screen Rant described the character as "quirky" and "bring[ing] depth" to the story, calling him "an easy-to-like character" and praising his design "with [its] multiple apples cleverly incorporated into his outfit",^[58] Polygon complimenting his depiction as "full of childhood whimsy".^[59] Catholic Review noted his depiction as "a mostly sympathetic figure [and] misunderstood rebel."^[60] The Illuminerdi lauded Jordan's vocal and acting abilities in his performance of "Hell's Greatest Dad" as "really add[ing] a comedic level we hadn’t seen before [while shining] a light on the type of fantasy filled dreamer Lucifer can be."^[61]

Study Breaks criticized Lucifer's "flawed idealism" while noting how "there's something about the devoted father-figure that really speaks to fans of the show".^[62] Hot Air dismissed Lucifer's depiction as a "good guy" as "trolling" while still noting how "there is a case to be made for his portrayal".^[63] BlazeTV similarly condemned Lucifer's depiction in the series as "heretical" and "ignorant of Christianity",^[64] Medium criticising his appearance as "a complete thud [with] nothing to make him stand out visually".^[65] The Washington Times also condemning this depiction as "unbiblical and an attempt from the enemy to twist the truth [and] lead one astray from God".^[66] Geek Girl Authority lauded Lucifer as a "favorite character", praising Jordan's "swoon-worthy Broadway tenor" in delivering his lines as "perfect for a literal angel".^[67] American Family Association criticising the series "mak[ing] light of Satan [as] a positive spin on evil".^[68]
