Alastor/Relationships

Charlie Morningstar
Alastor 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".

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.

In “Hello Rosie!”, 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, a subtle sign of respect. Later he assists in recruiting canibals and that he recognized her potential all along and that he could mold her.

In “The Show Must Go On”, Charlie is visibly saddened by his ‘death’ and thrilled when he returns at the end.

According to Vivziepop in one of her streams, Alastor thinks Charlie is funny and likes talking to her.

Vaggie
Alastor and Vaggie'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 Vaggie and does so on numerous occasions for his own amusement, with taunts or invading her personal space. It appears that Alastor does not take Vaggie'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 “The Show Must Go On”, Vaggie is happy when he returns at the end.

Niffty
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.

Niffty 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 “The Show Must Go On,” Alastor 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 returns at the end.

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.

Husk
Husk does not appear to 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.

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.

As revealed in Dad Beat Dad, Husk is the only known person to be privy to Alastor's darkest secret: he had sold his soul to another demon. Alastor made it clear that he will kill him, and "broadcast his screams" on his radio show if he ever mentions it again, with him being uncharacteristically seething with rage.

In “The Show Must Go On”, Husk is visibly upset when he returns at the end

Lucifer Morningstar
In "Dad Beat Dad", 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 returns at the end

Alastor 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.

Angel Dust
It is currently unknown what Alastor's thoughts on Angel are, though it is believed that he is largely indifferent to him; 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.

In “The Show Must Go On”, Angel is happy when he returns at the end

Sir Pentious
Despite Sir Pentious claiming to have had 20 battles with Alastor, Alastor does not recall him and is dismissive of him altogether; it is presumed that he does not think much of Pentious.

In "Radio Killed the Video Star," he says he remembers and thinks about him now after he tore off a piece of his coat. He seemingly accepted Sir Pentious' apology and gave a compliment about how he was one of the few to tear such a piece off of his coat before he burned it.

Mimzy
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 hating being touched by others. Due to their long friendship, Mimzy knows Alastor 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 loansharks she borrowed 50k from and apparently stole a car from (which she then crashed into the loan shark's girlfriend). With Mimzy fully expecting 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 a 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 and implying to 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 loansharks, 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 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.

Egg Boiz
He was ordered by Vaggie to get rid of the Egg Boiz. He showed enthusiasm until he was ordered to get rid of them humanely, which he said was "a lot less fun."

During a walk to Carmilla's building, the Egg Boiz talk a lot and ask a lot of questions to him, which visibly annoyed him. Upon encountering Zestial, he orders the eggs to "follow in silence" if they want to stay alive.

Upon arrival, he orders the eggs to stay at the entrance and guard. However, one of the eggs, Frank, accidentally went in the building with Alastor and Zestial.

When Alastor became interested in what was going on with Carmilla and the dead Angel, he orders Frank to follow them and gain information.

Alastor awaited for Frank at the elevator and when he came back, he asked what he heard. He was intrigued by the fact that Carmilla killed the Angel, and he asks Frank to keep the information a secret between them.

After arriving back at the hotel, he said to Vaggie that the Egg Boiz have "proved to be rather useful."

Rosie
Alastor and Rosie are good friends. He describes Rosie as a "dear, charming and dangerous" person who he loves to spend time with. It is apparent that the two get along very well, as they are subsequently seen together, and both enjoy each other's presence. It is also seen that they share several ideas together, and both are always willing to help the other. In the The Radio Demon comic, Alastor greets several girls in the Cannibal Town and afterward asks them to give Rosie his regards.

In “Hello Rosie!,” Alastor and Rosie interact on screen, displaying a very positive relationship, complimenting each other and dancing and singing together.

On Twitter, Vivziepop stated that Alastor and Rosie's relationship is very similar to Jack and Mary's relationship in Mary Poppins Returns.

According to Faustisse, Alastor considers Rosie, along with Niffty and Husk, to be his only close friends. They think that Alastor and Rosie have known each other for a while.

Vox
According to Vivziepop, the two don't get along due to their different views and preferences when it comes to technology. Vox also has an one sided obsession with Alastor, trying to get him to notice him, which he does not feel the same.

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!"; upon getting some distance away, Alastor quietly grumbles and swears, calling Vox obnoxious, pompous, egotistical, and annoying.

Their rivalry and distain for one another 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. Furthermore, their duet, "Stayed Gone", emphasizes their respective stances on technology and even their past with Alastor mentioning how Vox asked him to join his team but 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.

Zestial
In "Scrambled Eggs," Alastor and Zestial meet during a walk with the Egg Boiz to Carmilla's building for a meeting. He was visibly on edge upon encountering and walking with him. They both talk about Alastor's 7-year absence, although he says that his absence wasn't anything serious but was interested to hear the "theories" about what they think happened.
