Summary
(Alastor is a rather tall, beige-skinned, and dapper humanoid deer-like sinner demon who is usually seen with a broad smile full of sharp, yellow teeth inside. He is at around the same height as his rival, Vox, with the two standing at approximately 7 feet tall. His hair is a hot pinkish-red, styled into a cropped, angled bob cut with black ends, and an undercut on the back. Atop his head are a pair of small black antlers from the crown, as well as a pair of large deer ears covered in his hair with black tips. His eyes have red sclera with brighter-colored irises and slit-like pupils, and dark red eyelids with the color extending to his eyebrows in a way that mimics eyeshadow. His forearms and lower legs fade to black, and he also has red hoofed-toes and red claw-like fingers. Alastor wears a red pinstriped coat with a darker high collar and long sleeves with brighter-colored cuffs, white-trimmed darker-red lapels, and the hem being slightly ragged. Under his coat, he wears a rather long, untucked bright red dress-shirt with a black cross on the chest. He also wears black dress pants with cuffs matching his coat, and red pointed-toed dress shoes with red deer hoofprints emblazoned on the soles. He accessorizes with a black-knotted bowtie with a bright red center, and a small, oval-shaped, black-rimmed red monocle which he wears over his right eye. He also carries a thin staff with a sentient, vintage-style microphone at the top, 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 Alastor 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.) (Personality 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. 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. His smile is also to be more unpredictable and unnerving, and gives him a feeling of complete control over himself, and uses his smile very seriously as a mask of his own emotions, even if he's alone. Alastor is described as a man of duality. He values good manners, affability, and intelligence very highly in others, and will actively look down on those who do not meet his standards, however, he will often play fast and loose with these arbitrary rules in regards to himself and his own conduct. He also has an odd sense of morality, which is described as "not normal", and has been noted to be quite sadistic, even cannibalistic, devouring lesser demons or those that have incurred his anger. 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. Alastor's desire to want to help Charlie run the Hazbin Hotel is put into question given his initially being there was forced by a deal. He claims he came for his own amusement and as a fun distraction from his decades of boredom, with hopes for the Hotel's failure over siding with Charlie's idealism, and dismissing the idea that redemption is possible as laughable. Nevertheless, he fulfills his role as patron as promised, providing the Hotel with staff, assisting with maintenance, and protecting Charlie and her business from outside threats. Although he shows a reluctance to truly help at the Hotel, Alastor rarely displays concern for the residents and has grown fond of some of them. Alastor does also seem to have a genuine deep respect for Charlie for her indomitable will and optimism in the face of dangerous threats such as the Exorcists and Vox. Vivziepop explains that Alastor admires people who can take a lot of abuse, pain, rejection, and ridicule, and still be able to "smile through it", even when Charlie is not smiling through that, her spirit and resolve is not lost, which he authentically admires about her. Despite consistently having a confident and cheerful demeanor, he harbors a vulnerable side that becomes apparent when confronted with reminders of being "chained". Following his defeat at the hands of Adam, his facade of certainty crumbled, and he succumbed to panic attack. Alastor then remained distant from Charlie's requests to help at the Hotel due to his frustration and humiliation, in addition to the mockery from Lucifer and Rosie. 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", and is also "kind of one of the worst". In life, Alastor was aware that his actions earned his condemnation to Hell. In order to prepare, he performed a ritual to contact Rosie, asking to secure himself amongst the top demons to continue his "fun" and avoid being a "tortured soul", and she made a deal with him so that he would become the strongest sinner in Hell. When he was killed the following day, Alastor hated being reminded of his death and was forced to become Rosie's "pet", faithfully following her orders, much to his frustration at the loss of his autonomy. Alastor is cold and manipulative, seizing every opportunity to make a larger move later. To free himself from Rosie's deal, he becomes Vox's prisoner in exchange for him never laying his hands on Charlie, but making it seem like the deal was to never harm her. During his captivity, Alastor slowly manipulates Vox to inflate his ego, distance himself from the Vees, and ultimately use Charlie and Vox to free himself from Rosie, as well as break their own deal when Vox touches Charlie's shoulders. He then entered a new deal with Rosie to repair his staff in exchange for helping contain the overloading Might of Lilith to prevent it from wiping out half of Pentagram City.)

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. Across multiple parts of his suit, and the ends of his mouth, also gain green stitches along them, while the red of his shoes split to form hoofed toes.
Valentino has a negative opinion of Alastor, and while aware of his enmity with Vox, doesn't care much for it. In "Radio Killed the Video Star", he mocks Vox's obsessive hatred of Alastor, revealing Alastor's unexpected return to him and that he now resides at the Hazbin Hotel. In "The Show Must Go On", Valentino and Vox celebrate Alastor's disappearance after his defeat by Adam. In "It's A Deal", Valentino arrives alongside Vox and Velvette for a battle against Alastor. Valentino faces Alastor one-on-one and manages to land a punch to his chest, causing him to spit blood. Due to Alastor's minions, Valentino wasn't able to shoot him with his gun. While Alastor and Vox were discussing their rivalry, Valentino suggested that they should have sex after noticing the tension. As shown, also asked if he could film them doing the deed, finding the idea of watching them stimulating. As indicated, Valentino has at least some respect for Alastor and seeing him above his employees that he abuses as a fellow Overlord. As shown in "Silenced" and "Scream Rain", Valentino has become increasingly off put by Alastor and Vox's relationship, especially with how easily Alastor is able to get underneath Vox's skin. Vivziepop thinks that Alastor would weirdly get along with Valentino and Velvette, which would piss off Vox even more. She says that if the writers had more runtime or episodes in Season 2, they wanted more time spent with Alastor hanging out with Valentino and Velvette. However, by "Weapon of Mass Distraction" and "Curtain Call", Valentino has gotten fed up with how Alastor has brought out the worst in Vox, who is obsessively trying to win Alastor's impossible approval. In fact, he even yells in anger and anguish at Vox by calling Alastor a "stupid deer" before decapitating Vox, showing his current hatred for the Radio Demon.
Although it isn't clear how she feels about him, Velvette taunts the other Overlords, including Alastor, for their age and supposed cowardice. In "It's A Deal", Velvette aids Vox and Valentino in a battle against Alastor. Velvette faces Alastor one-on-one and uses her arrows to break through his shield. She is easily taken down however, when Alastor uses his shadow to drop her onto a car. As shown in "Scream Rain", Velvette maintains a neutral position in regards to Alastor as he resides with them in V Tower as Vox's prisoner. Vivziepop thinks that Alastor would weirdly get along with Valentino and Velvette, which would piss off Vox even more. She says that if the writers had more runtime or episodes in Season 2, they wanted more time spent with Alastor hanging out with Valentino and Velvette. In "Curtain Call", Velvette situationally helped Alastor, the Hazbin Hotel group and the other Overlords put a barrier around the Might of Lilith to prevent its destruction from decimating half of Pentagram City.
Alastor and Vox are bitter rivals. Unlike Vox's immense and profound hate for him, Alastor does not reciprocate, considering Vox more of an annoying enemy and enjoying mocking him to manipulate him. Alastor and Vox used to once be "friends" 70 years ago. On Vox's side, he genuinely admired Alastor and found him to be an inspirational figure, even developing a crush on him. The closeness between the two Overlords reached the point where Alastor was informed of Vox's true name when he was human, which was Vincent. At an unknown time during "It's A Deal", they went to a bar, where Vox proposed a partnership between them. Alastor manically laughed at him, thinking he wasn't serious at first before realizing he was and telling him he's that pathetic and weak that he needed him to join him. From this point on, Vox held a grudge against Alastor for this, but still has a one-sided obsession with Alastor, trying to get him to notice him, which Alastor does not reciprocate, showing little interest in Vox at all. Alastor has mentioned his opinion of Vox being that he has to frequently rely on others for his power. As seen in "The Show Must Go On" a ripped picture of Alastor and Vox is seen. According to Vivziepop, the two don't get along due to their different views and preferences when it comes to technology. In The Radio Demon comic, Alastor briefly sees Vox's advertisements while passing by a store. When confronted by Vox, Alastor states he is a "show off" who's "all hat and no cattle!" before walking away with a shrug; upon getting some distance away, Alastor quietly grumbles and swears, calling Vox obnoxious, pompous, egotistical, and annoying. Their rivalry and hatred for each other is made clear in "Radio Killed the Video Star". Seven years prior to series, Alastor and Vox engaged in a confrontation where Alastor nearly beat him; although Alastor makes comments at different points that he was the victor, describing himself as "putting Vox in his place". Furthermore, their duet, "Stayed Gone", emphasizes their respective stances on technology and even their past with Alastor mentioning how Vox had asked him to join his team, but he had declined. Through Alastor's battle with Adam in "The Show Must Go On", Vox is constantly rooting for Alastor's defeat and death, being ecstatic when he is defeated, saying it is "better than sex," and immediately growing upset when Alastor escapes. In "It's A Deal", Alastor proposes a deal with Vox, in which he could imprison him on the condition he had to stay away from Charlie. Vox immediately takes the offer and throws a whole parade with him proclaiming he "won", while also subjugating Alastor to various antics to humiliate and annoy Alastor, embarrassing Alastor on live television, buying himself a smoothie and drinking it in front of a gagged Alastor, and doing the deed with Valentino in front of Alastor to annoy him. Although visibly still mad about their past, Vox goes on about how he won't let Alastor get to him since he's changed and is focused on another goal. However, Alastor remains unfazed despite his own earlier discomfort, even having the gall to mock Vox. As shown, Alastor revels in the power he has over Vox, being fully aware of Vox being obsessed with him and his subconscious desire to get his approval and impress him and uses it to his advantage in "Silenced" and "Scream Rain". When he temporarily resided with Vox, Valentino, and Velvette in V Tower as Vox’s prisoner, Alastor has taken full advantage of his position to mock and insult Vox, subtly manipulating him as Alastor turns him against Valentino and Velvette by making him push them away due to him trying to prove his superiority to Alastor by lording over them, treating them as lackeys rather than equals. As implied by how Alastor mocks and insults Vox, Alastor was aware of his former feelings for him. As shown in "Weapon of Mass Distraction", Alastor displayed a profound understanding of Vox's character, understanding full well that Vox was "broken from the start" on a deep, fundamental level as no victory he achieves, no matter how great or impressive, will ever be enough to truly satisfy him. Since being imprisoned by Vox, Alastor has confirmed that he has been completely manipulating Vox since the start, describing him as being "too easy" and Vox has been completely oblivious to him doing so. In "Curtain Call", Alastor finally manages to break free from Rosie's deal after convincing Charlie to declare Vox the most powerful sinner in Hell, which led Vox to "lay his hands" on her shoulders, thus breaking the agreement between Alastor and Vox. Although Vox argued that he never hurt Charlie, Alastor made it clear that he had manipulated him using a technicality, since he wasn't supposed to touch Charlie with his hands, much to his rival's frustration. Having regained his full power, he seizes a valuable opportunity for a worthy duel with Vox, leading them to battle in their demonic forms throughout the city. When Alastor was seizing the advantage and even overpowering Vox, the latter summoned his pet shark, Shok.wav, to back him up, something for which Alastor mocked Vox, calling him outt that he still couldn't take the Radio Demon one on one, needing to call on his "little doggy". After falling to the ground alongside Charlie and Emily, Alastor's taunts cause Vox's mind to snap, and he becomes willing to overload the Might of Lilith if it will allow him to kill Alastor, who simply smiles sadistically before being defeated by the Vees.
Vivziepop thinks that Alastor and Mimzy may have known each other in their living lives. She gives their familiarity as the reason for their good relationship in the hotel. Furthermore, when asked about Alastor and Mimzy, Vivziepop stated the two of them would get along due to them having a similar timeframe that they existed in. Vivziepop describes Alastor as finding Mimzy extremely charming, although he is the only one who sees this in her, as she is "absolutely terrible" to everyone else and this causes them to dislike her. As revealed in "Dad Beat Dad", Alastor and Mimzy are old friends, having known and befriended each other back when they were alive as humans. As Mimzy revealed, the two of them frequented a jazz club together and enjoyed drinking and dancing together. This friendship continued when the two fell into Hell. As shown where Alastor would warmly greet Mimzy by hugging her despite normally hating being touched by others. Due to their long friendship, Mimzy knows Alastor's personality and history intimately. However, despite their friendship, it is also apparent that Mimzy uses Alastor for her own ends, as shown where she went to the Hazbin Hotel to hide from the loan sharks she borrowed 50k from and apparently stole a car from (which she then crashed into the loan shark's girlfriend). Mimzy fully expected Alastor to dispatch the loan sharks when they came searching for her, showing that Mimzy is fully willing to take advantage of Alastor's immense power and influence as an Overlord for her own benefit. As stated by Husk, Mimzy only goes to Alastor when she wants something, implying to her having caused numerous incidents such as this one in the past. Alastor in turn is fully aware of Mimzy's selfish personality and knows that she takes advantage of him to "clean up" the messes she makes. Alastor however has stated that he doesn't mind helping her and that he can handle whatever mess Mimzy gets herself into, showing Alastor's fondness for his old friend. However, as shown in the end of "Dad Beat Dad", it becomes evident that there are boundaries to what Alastor can endure from Mimzy. Following the chaos she unleashed with the loan sharks, Alastor tells her to leave and to not return to the hotel, with him warning her that he will not tolerate her endangering the hotel and its residences due to her selfishness, only allowing her to stay if she is genuinely interested in redemption. Mimzy, shocked at this statement, was surprised for his genuine concern for the hotel. Insulted by Alastor's warning, Mimzy left the hotel. It is currently unknown if either Alastor or Mimzy have the desire to make up with each other.
It is currently unknown what Alastor's thoughts on Angel are, though it is believed that he is largely indifferent to him partly because Alastor's asexuality causes him to turn down Angel's sexual advances; it is noteworthy that Alastor was visibly taken by surprise by Angel's offer for a blowjob, but quickly regained his composure and swiftly turned down the offer. It happens again in "Overture" where Angel suggests filming a porn of him having sex with Alastor as a commercial. Alastor sarcastically laughs it off and tells him it will never happen. In "Dad Beat Dad", Angel is surprised by the close friendship between Alastor and Mimzy, commenting on Alastor's shadowy and enigmatic attitude when he first met him at the hotel, before being shocked about hearing Alastor's history and rise to infamy. In "The Show Must Go On", Angel is happy when he returned after being presumed dead. In "It's A Deal", Angel and Cherri make fun of the disputes between Alastor and Lucifer.
Lucifer is the scorned rival of Alastor. In "Dad Beat Dad", Alastor demonstrates haughtiness towards the King of Hell, and the two begin their rivalry as soon as Lucifer shows jealousy towards Alastor when he begins showing his "deep" bond with Charlie for his support of her dreams and goals of the Hazbin Hotel. Lucifer was threatened by Alastor taking Charlie away from him, and was incensed when Alastor pointed out how little support Lucifer had given Charlie in her dreams, Lucifer became increasingly insecure about his father-daughter bond with her and began to fight with Alastor to get Charlie's attention. Vivziepop explains 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. Alastor is also shown to be somewhat petty when it comes to Lucifer, casually making smug comments about Lucifer's height. Though surprisingly, Lucifer himself can irritate Alastor enough to somewhat chip away at his normally composed facade, even causing Alastor to drop all pretenses and swear at him. In "The Show Must Go On", Lucifer is visibly disgusted when he returned after being presumed dead. Despite Lucifer's status in Hell and his powers being much greater and more powerful than Alastor's, he is not intimidated by Lucifer. Vivziepop and Dave Capdevielle both stated that Alastor in no way would be afraid of Lucifer; and that there is mutual respect going on between them. In "New Pentious", Alastor mocks Lucifer's height while Lucifer's in his pyjamas before throwing a rubber duck at his face. When Lucifer arrives to rescue Charlie, Alastor gives him a congratulatory nod while his rival makes snide remarks about his status. In "It's A Deal", Alastor was mocked by Lucifer to the point where he quit the hotel, but as he was leaving, his shadow purposely spilled Lucifer's coffee onto him and his suit. In "Weapon of Mass Distraction", when Lucifer is tricked and kidnapped by Vox to be used as a power source for the Might of Lilith, Alastor taunts his rival for his inability to guard his weakness of not killing sinners, causing Lucifer to respond aggressively before they are interrupted by Vox. In "Curtain Call" after Vox's defeat and the hotel is back in business, Alastor still carried a grudge against Lucifer and his reasons for returning to the hotel seem to involve him.
Husk does not have friendly feelings towards Alastor, having had his soul be owned by him. In the pilot, while he is surly towards most people, Husk displays open and unafraid disdain towards Alastor when forcibly summoned to the hotel, being furious instead and not shy to let Alastor know it, going so far as to physically shove him. Long ago, Husk was an Overlord who through gambling the souls he owned went on a losing streak when he met Alastor. Husk gambled his own soul against Alastor and lost it along with his freedom to him. Vivziepop explains that for Husk that Alastor has his own personal agenda and Husk is just mainly there to help him achieve it here and there when Alastor needs it. His genuine fear only manifests when Alastor directs his anger specifically at him. This fear is most pronounced when Alastor summons the chains, reminding Husk of the ownership Alastor holds over his soul. In these moments, Husk visibly trembles with apprehension. Conversely, when Alastor directs his anger toward others, Husk adopts an outwardly indifferent demeanor. Alastor is aware of Husk's vice for alcohol and is happy to indulge him in it as a means of bribery. After arriving at the hotel, Husk demands to know what Alastor wants with him "this time", implying Alastor has summoned him on other occasions, with Husk being pictured alongside him as he destroys souls in Vaggie's tale. Vivziepop has described Alastor's view of Husk as less than flattering, stating that he sees him as a sad and lonely drunk. According to Faustisse, Alastor considers Husk, along with Niffty and Rosie, to be his only close friends. It is unclear whether Husk returns this sentiment. In "Overture", Husk complains about how he is forced to be in the hotel because of his agreement with Alastor. As revealed in "Dad Beat Dad", Husk is the only known person to be privy to Alastor's deepest, darkest secret: that he had sold his soul to another demon. Alastor made it clear that he will tear Husk's soul apart and "broadcast his screams" on his radio show if he ever mentioned it again, with him being uncharacteristically seething with rage and Husk nervously obeying without question. In "The Show Must Go On", Husk is visibly upset when he returned after being presumed dead. In "New Pentious", Husk asks Alastor about helping Charlie while she was under pressure from reporters, but he claims that while he should help her, he won't because he likes being difficult, much to Husk's frustration. In "It's A Deal", Husk is forced by Niffty to help Alastor in his battle against the Vees. When Alastor offers Vox a deal: to become his prisoner in exchange for freeing his associates. Husk is surprised by his decision, and although he detests Alastor for the deal, he shows a little concern for him.
As shown in the pilot, Alastor and Niffty are acquainted with each other, and both Husk and Niffty are silhouetted behind Alastor in the overlord line-up in the pilot. Niffty seems to have a positive view of Alastor. Out of the hotel staff, Alastor appears to have the closest relationship with Niffty. She is one of the few characters that Alastor allows to climb all over him. Vivziepop thinks Alastor is very fond of Niffty, which is something that she says has lasted throughout every iteration of the characters; she also thinks Alastor finds Niffty as really fun and endearing. In "Radio Killed the Video Star", Niffty climbs onto Alastor's hair before he fights Sir Pentious, and when she asks him who the Vees are, he tells her they are not important people. In "The Show Must Go On", Alastor tells Niffty that the residents of the hotel are an enjoyable group to be around and that he could get accustomed to them. He allows Niffty to place a crown of roaches on his head, calling him the "Roach King". The two then share a laugh about the inner workings of Niffty's mind. She is visibly happy when he returned after being presumed dead. Faustisse described Alastor's view of Niffty as like his "obnoxious adopted daughter". They joked that he finds her adorable, but also stupid, and that he would also forget her name. According to Faustisse, Alastor considers Niffty, along with Husk and Rosie, to be his only close friends. In "It's A Deal", Alastor has the crown of roaches hung over a vanity mirror in his hotel room, indicating that he values it. Later in the episode, Niffty, accompanied by a reluctant Husk, rushes to Alastor's aid in his battle against the Vees. When he sees Niffty about to be shot by Valentino, Alastor shows genuine concern for her and seizes the opportunity to strike a deal with Vox to become his prisoner in exchange for Niffty and Husk's release alongside Vox not laying a hand on Charlie. As is shown in "Scream Rain", Alastor left a tray of food with a note for Niffty before becoming the prisoner of Vox.
Alastor and Vaggi's relationship started hostile, with her threatening him at spear-point, referring to him as a "pompous, cheesy, talk-show shitlord". It is presumed that Alastor is aware of how easy it is to rile up Vaggi and does so on numerous occasions for his own amusement, with taunts or invading her personal space, including literally pushing her about during their first meeting. It appears that Alastor does not take Vaggi's threats seriously due to being one of the Overlords of Hell; he even mentioned that if he truly wanted to hurt them, he "would have done so already". In "Overture", despite her cautions of him, he was able to get her to strike a seemingly harmless deal with him, in which he would provide the means to produce a quality commercial for the hotel, if she never asked him to participate in a screen production ever again. In "Scrambled Eggs", he is called by Vaggi to help her get rid of Sir Pentious' Egg Boiz, and although he initially was going to dispose of them inhumanely, she asked him to do it humanely, forcing Alastor to follow her order. In "Hello Rosie!", Alastor terrifies Vaggi with his deal with Charlie, causing Vaggi to go on the defensive against Alastor, who mockingly stated that the deal was not to take Charlie's soul. Despite her hostility towards him, in "The Show Must Go On", Vaggi is happy when he returned after being presumed dead. In "New Pentious", Alastor mocks Vaggi's job as a receptionist because of the new clientele at the hotel before she asks him for help because of his job as the hotel host, but he teleports away instead of answering her.
Alastor shares a complicated, situational view on his alliance with the Princess. He assists Charlie with her endeavors, but he makes it abundantly clear that he is only doing it for his interests, as opposed to believing in Charlie's ideas of redemption. However, they have a similar sense of humor. In his reprise, he tells Charlie that he thinks she's "one of a kind" as well as a "charming demon belle". According to Vivziepop in one of her streams, Alastor thinks Charlie is funny and likes talking to her. In "Dad Beat Dad", Alastor proclaimed that Charlie is like the daughter he never had. However, Vivziepop stated that she doesn't know how authentically fatherly Alastor is, as in the episode he wanted to get under Lucifer's skin and bother him and used Lucifer's wanting a relationship with his daughter to do so. During the song, Hell's Greatest Dad, Alastor, who is aware of Charlie's troubled relationship with Lucifer, also knew exactly how to win Charlie's trust for him by claiming that he's very faithful and steadfast when it comes to serving her, and how she should pick the path of least resistance. This shows that he is well aware of the princess's naivety enough to get on her good graces. In "Hello Rosie!", Alastor teases Charlie about her current predicament and, Charlie tells him to go away since she is having a bad time, and while she questions how he can be smiling when they are failing and struggling, Alastor tells Charlie the value of a smile, and offers her a binding deal for information in exchange for a favor at the time of his choosing. Later, he takes her to Cannibal Town, assisting her by lending her his staff, and with recruiting the cannibals, saying that he recognized her potential all along and that he could mold her, making her a valuable ally. In "The Show Must Go On", Charlie is visibly saddened when she believed Alastor had been killed by Adam, and thrilled when he returned at the end. In "New Pentious", instead of helping with the Hotel's growing clientele and Charlie's pressure from reporters, Alastor openly refuses to because he likes being difficult when asked by Husk about helping her. In "Hazbin Hotel: Behind Closed Doors", Alastor is seen to be visibly annoyed by Charlie's presence as she excitingly wants to tell him about the news of redemption. As is mentioned in "It's A Deal", it is revealed that Alastor's objective in supporting the hotel was at Rosie's request. As shown, despite his personal fondness for Charlie, Alastor has become fed up working/protecting her "stupid hotel" and eventually became fed up enough to try and quit. As shown during his visit to Rosie, Alastor mentions that he and Charlie were distancing themselves, mainly due to her no longer needing his help much, before Rosie stopped him because it was her order that he be at the hotel. As shown, Alastor's dissatisfaction with his situation in the hotel and his continued servitude to Rosie has lead him to scheme to escape his deal with Rosie and finally abandon Charlie and the hotel. As part of his secret plan, Alastor offers Vox a deal: to become his prisoner in exchange for him never "laying his hands on" Charlie. As shown in "Weapon of Mass Distraction", during his time in Vox's captivity, Alastor has admitted some genuine attachment to Charlie, admitting her persistence, belief in the innate goodness of Sinners, the causes that she believes in, and her refusal to back down and bend to anyone's threats that reject and dissuade her dreams as being extremely entertaining and her greatest strength. Vivziepop says that Alastor's line to Vox about there being nothing he can do to break Charlie's spirit in "Weapon of Mass Distraction" is a hint of what he authentically admires about Charlie; being able to "smile through" all the abuse, pain, rejection, and ridicule, and even when she is not smiling, her spirit and resolve is not lost, which he admires. This shows that Charlie means something to Alastor, even though he doesn't really know she means something to him. In "Curtain Call", Alastor uses his deal with Charlie to break out of his other two deals with Rosie and Vox, prompting her to declare Vox was the strongest sinner, resulting in his deal with Rosie to become void as a result. Despite no longer needing to stay or assist with the hotel, something Alastor admitted to Rosie he disliked, the Overlord elected to remain nonetheless.
Alastor's power appears to mostly comes from his staff. However, as his staff was broken by Adam in "The Show Must Go On", his powers were weakened, causing Alastor to ask Rosie to fix his staff in "It's A Deal", and he was shown in the same episode to have difficulty activating some of his powers against the Vees.
