Alastor.

Alastor does not like anyone invading his bubble, and dislikes being touched[12] and will go out of his way to avoid it, usually in the most off-putting way possible. Vivziepop described him stretching and snapping his neck in unnatural contortions to avoid his hair being touched and creep out whoever has tried to touch him.[13][14][81] He can also dematerialize to avoid things.[82] Conversely, Alastor does not respect the personal space of others at all, being very handsy and comfortable invading the space of others[12] and shown grabbing and pulling around Charlie, Vaggie, and Husk numerous times in the pilot. Alastor wears gloves.[note 8] They are charcoal grey with red tips at the nails. Vivziepop describes his breath as "not good".[83] Faustisse makes reference to him having black gums.[note 9] The red treads on the soles of Alastor's shoes resemble deer hoof tracks.[84] He also has antlers, as well as the ears of a deer.[30] His ears have been shown to lower at times of certain negative emotions, such as the mention of Susan in "Hello Rosie!" and during his panic attack in "The Show Must Go On". Alastor's pilot voice is shares the same voice actor as Joe, Jesse, Striker ("Western Energy" onwards), and the unnamed hellhound from "Queen Bee" of Helluva Boss, with all of them being voiced by Edward Bosco. Vivziepop talked about Alastor being one of the hardest characters for her to draw and animate, as she has a very specific image of him in her head that she admits can be challenging for her to reach.[85] In a stream, Vivziepop mentioned that Alastor would like Willy Wonka because he's "a showy dick". She also explains that Alastor has a line where he doesn't like people who are too much like himself but likes those that are enough like himself.[86]

Alastor interacts on better terms with women in general, and is much lighter in his view of them. He doesn't view many of the other powerful male characters within his circle as providing any substantially intelligent conversation, seeing them as "stupid idiot brutes" and not thinking very highly of them for the most part. Others, such as Angel Dust and Husk, he finds pitiable.[35] Alastor greatly values manners in others and is personally offended by disrespect and rudeness. He also values humor, enjoying when people can give him a good view of their misery.[34] Alastor is one of the few Sinners who has not taken on a new name in Hell. Instead, he keeps with his true name from his living life, as he is not a fan of making nicknames for himself.[1] He is, however, happy to be referred to as "Al".

When asked about who is the better dad between Alastor and Lucifer, Vivziepop answered that it would be Lucifer, stating that she doesn't know how authentically fatherly Alastor is, explaining that in "Dad Beat Dad" Alastor wanted to get under Lucifer's skin and bother him and used Lucifer's wanting a relationship with his daughter to do so.[76] Alastor's jovial remark on there being "so many orphans" during the stock market crash of 1929 in the pilot, implies he is apathetic to children's suffering. Alastor is canonically asexual. On earlier development streams for the pilot, Vivziepop was more explicit about his also not being romantically inclined, but later prefers to take the approach of allowing fans to "have fun" with his character, while simply reminding them he does have a specific direction within the canon of the show itself.[19] Vivziepop doesn't think the question of his romantic orientation is story-relevant and cites part of the reason being Alastor's love for himself and that no one else can measure up to it. Vivziepop also doesn't think that Alastor is aware of the specific modern label applied to his sexuality, but she is writing him with that orientation clearly in mind.[32][77] Faustisse confirmed on their own separate streams that Alastor is, in fact, still aromantic within the show, but also echoed Vivziepop's sentiments about allowing the fandom to have respectful fun.[note 3] When pressed on whether she thought Alastor had ever been intimate, Vivziepop said she didn't think so, but added that she did not spend much time thinking about Alastor's personal life at all.[78] Alastor is capable of forming friendships and can become fond of people, although in his own particular way. He becomes fond of people he sees as especially funny or entertaining.[79]

Alastor was created to the song "You're Never Fully Dressed Without a Smile" from the musical Annie,[70] and specifically the London cast recording inspired his voice.[71] When asked what Alastor's favorite song would be, Vivziepop answered that it would be the one that inspired his creation, "You're Never Fully Dressed Without a Smile". As for songs specific to Alastor's time period, Vivziepop stated it would be "Smile" by Charlie Chaplin. Cab Calloway was also mentioned as a favorite singer, with an emphasis on Alastor's love of jazz in both life and death.[70] According to Vivziepop, Alastor does like musicals and appreciates them more than the average demon, liking much more old-timey vaudeville and really liking pre-1930s musicals, but he wouldn't understand more modern musicals and probably would not like Shrek the Musical.[72] Alastor can play several instruments, including the piano, violin, trumpet, and saxophone. Vivziepop has also partially joked that it is part of Alastor's canon that he both owns, and can play a "Furby organ".[73] Faustisse thinks that Alastor loves the fact that he scares people.[note 7] Alastor is not a fan of modern technology and doesn't like using any technology that was invented after he died. This plays a part in his not getting along with Vox, who has fully embraced it.[16] Alastor is said to not be a big fan of children, and although he wouldn't kill a child, he would strike one if they annoyed him too much, believing in "that kind of discipline".[74] He also won't take responsibility if the child accidentally injures itself when he lets them play.[36] Vivziepop thinks Alastor would be a bad father, although a better mentor figure.[75]

Although Alastor is not a hard drinker, he does favor the hard liquors when he chooses to drink, such as whiskey. Vivziepop cited his New Orleans background for his "party side", emphasizing that he is a "classy drunk, not a messy drunk".[4] In "Dad Beat Dad", Mimzy stated that he becomes a "kitten" if he drank enough rye whisky while jazz music was on. Alastor likes black coffee, but does not like tea.[8][60] Alastor is a big foodie and enjoys cooking.[5] He is also something of a food snob, and hates "lazy" processed foods.[61] Vivziepop thinks Alastor probably isn't much of a fan of sweet things either, preferring bitter tastes, like meat and whiskey.[7] Alastor enjoys meat raw.[62] According to Faustisse, Alastor, alongside Charlie and her mom, are fans of pineapple on pizza.[note 5] Ironically, Alastor's pilot voice actor, Edward Bosco, dislikes pineapple on pizza.[63] Alastor has never eaten McDonalds before.[64] Alastor enjoys occasionally impromptu joining in with bands that are playing. He loves to cook and prepare dishes, although in his own way as he prefers his meat raw. He also enjoys playing pranks on others.[6] Alastor enjoys visiting the Cannibal Town and frequents the cafes there, relating a lot to the residents and enjoying the food.[65] When asked exactly what Alastor's powers are, Vivziepop stated that they are "lots of things", and that even she doesn't know all of them, yet. Alastor is a character that keeps many abilities hidden as he enjoys being unpredictable. He will sometimes feign an inability to do things that he can actually do, partly to subvert expectations, partly to be intentionally antagonistic and force the people around him to struggle with something he could easily have done.[66] Alastor can take on many forms.[67] Whenever Alastor uses his powers in the pilot, he is shown emitting a faint red aura. He can be seen using a form of Voodoo inspired blood magic as a means to defeat Sir Pentious in the pilot.

Alastor was stated to be from New Orleans, Louisiana, when he was alive.[4] Vivziepop expanded that New Orleans was where he lived and died as a person.[53] He was an only child.[54] His ethnicity was mixed-race Creole.[55][56] He was a radio show host and prolific serial killer.[2] Vivziepop describes him as "living that good life/his best life" while a radio star.[25] Vivziepop declined to give out details of Alastor's killings, but described him as "not going after just anyone", highlighting his "weird moral code". She emphasized his not being a direct parallel to any real world serial killer, instead describing him as sharing some similarities with the fictional serial killer, Dexter.[57] Faustisse does not think that Alastor was a cannibal while he was alive.[note 4] Alastor speaks with a Transatlantic (sometimes called a Mid-Atlantic) accent. A fashionable affect for American newscasters in the 1920s' to adopt, it was a combination of an idealized American accent and the clipped upper-class Queen's English used by the British Broadcasting Corporation in their "World Service" radio news. In the series, Alastor does have his radio voice filter at all times, but it sounds different and gets lighter to hear the actors voice a bit more at times.[58] Alastor can speak some French, although not fluently.[44] The pilot makes several references to Alastor's love for his mother. This was confirmed by Faustisse, who described him as "a momma's boy".[note 2] Alastor was a big theater person while living and would see everything. His general media preferences would be the "elevated horror" genre, as well as smart, dry comedies, such as the work of Buster Keaton.[9] When asked whether Alastor is afraid of dogs, Vivziepop stated that she doesn't think he's afraid of dogs (as was the case for previous iterations of his character), but that he actively dislikes them due to "backstory reasons" which involve his death,[15] an event he apparently did not appreciate.

While Alastor is powerful, he is aware that there are other demons and entities that rival him in terms of power, such as other Overlords. For this reason, he is wary around such demons, as they could potentially harm him if he is not careful.[41]

Despite everything, Alastor does genuinely seem to want to help Charlie run the Hazbin Hotel, albeit for his own amusement, and hopes for its failure over siding with her idealism. Alastor also dismisses the idea that redemption is possible as laughable, nevertheless, he fulfills his role as patron as promised, providing the hotel with staff, and protecting Charlie and her business from outside threats. He views the whole endeavor as a fun distraction from his decades of boredom.

Despite consistently having a confident and cheerful demeanor, he harbors a vulnerable side that becomes apparent when confronted with reminders of being "chained". In this instance, his facade of certainty crumbles, and he succumbs to panic attack.

According to Mimzy, when Alastor was alive he would become a "kitten" if he drank enough rye whiskey while jazz music was on. According to Vivziepop, Alastor may be "just kinda an asshole"

Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives a first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. His behavior, mannerisms, and even his voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, often using quaint anachronisms such as "the picture show" and refers to Charlie as a "charming demon belle".

This playful dandyish exterior, however, obscures a much darker side to him - one with high levels of self-importance - and he will not hesitate to use physical violence when others don't act in line with his very particular values or expectations. He is noted to be narcissistic, with his love for himself being stated that no one else can measure up to it, and he does not see many people quite up to his level.[32]

Alastor is described as a man of duality.[33] He values good manners,[34] affability and intelligence very highly in others, and will actively look down on those who do not meet his standards,[35] however he will often play fast and loose with these arbitrary rules in regards to himself and his own conduct.

Alastor has an odd sense of morality, which is described as "not normal",[36] and has been noted to be quite sadistic, even cannibalistic, devouring lesser demons or those that have incurred his anger. Despite this, he keeps close friends with the other cannibals of Hell, including the denizens at the Cannibal Town.

His smiling is a very self-enforced form of ego and a show of power and dominance; he looks down on anyone who lets their true emotions show, and even when faced with a rival in strength, if they let slip a frown, Alastor will see them as truly weak.[37][38] His smile is also to be more unpredictable and unnerving, and gives him a feeling of complete control over himself,[39] and uses his smile very seriously as a mask of his own emotions, even if he's alone.

Alastor is a slim, dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. He is at around the same height as his rival, Vox, with the two standing at approximately 7 feet.[29]

He sports a pinkish-red cropped, angled bob-cut with black tips at the ends, with a pair of large, black tipped deer ears[30] from the top of his head. The style has an undercut at the back, and two small black antlers protruding from the crown.

Alastor's eyes have dark-red sclera, bright-red irises and thin black pupils. His forearms and lower legs fade to dark grey, and he has red hoofed toes and red fingers.[31]

Alastor wears a red pinstripe coat with dark-red lapels piped with white, which is ragged along the bottom hem. Underneath this he wears a bright red dress-shirt with a black cross on the chest, and long black dress pants with matching bright red cuffs. He also wears a dark-red oval-shaped monocle, rimmed with black, over his right eye.

He accessorizes with a black knotted bowtie with a bright red center, black gloves with red at the fingertips, and black pointed-toe boots with red deer hoofprints emblazoned on the soles. Alastor also carries a thin staff with a sentient vintage style microphone attached to it, which he uses to play sound effects and broadcast his voice.

During his battle with Adam in "The Show Must Go On", his staff was broken and he received a slash to the chest, leaving an open gash that hasn't healed. Both his staff and gash are stitched up by green stitches he formed.

Full Demon: When in his full demon form, Alastor's body grows larger and limbs become longer, his neck gains extra joints, and his horns grow in size. In one scene in "Dad Beat Dad", Alastor has two sets of horns on his head. His sclera turn black while his pupils turn into the shape of radio dials. His suit and ends of his mouth also gain stitches along them, and the ends of his shoes split to form hoofed toes.
