Alastor

Alastor is the infamous entity known as "The Radio Demon", one of the many powerful Overlords of Hell, and a main character in Hazbin Hotel. He offered to assist Charlie in her endeavors.

Appearance
Alastor is tall and very thin, has grey skin, sharp yellow teeth, and short red and black tufts of hair/fur resembling deer ears. He has two small black antlers, which can grow in his demonic form. He has red in his sclera and a brighter red for the iris of the eyes, his pupils are black which can change into radio dials in his Radio Demon form. He always keeps a wide smile on his face.

Alastor wears a bright red dress shirt with two black marks that cross each other, underneath a pinstriped dark red coat along with burgundy dress pants, bow tie with a bright red knot, and black shoes with red deer hoofprints either emblazoned or engraved on the soles. He has a black oval-shaped monocle over his right eye, he also wears burgundy gloves with bright red marks showing where his nails and knuckles are. He carries a cane with a sentient vintage style microphone attached to it.

Personality
Alastor's behavior, mannerisms, and even his voice are similar to an old-fashioned radio announcer. As a result, he is always smiling and acts polite. The reason he never stops smiling is that he believes it shows power and dominance. If a rival were to frown then he would see them as weak. He is said to be narcissistic, not seeing many people quite up to his level. However, that does not make him reckless, as it's been said that despite being extremely powerful, Alastor is fully aware that there are other demons and entities that rival him in terms of power, as such he is wary around such demons for they could potentially harm him if he is not careful. He also seems to have a moral compass, but it's "not normal". Alastor has been noted to be quite sadistic and to have masochistic tendencies. Despite this, he seems to genuinely want to help Charlie run the Happy Hotel, albeit for his own amusement rather than idealism.

Background
Alastor is a former radio host and southern serial killer. He is from New Orleans, Louisiana.

He lived during the early 20th century, having witnessed the Stock Market Crash of 1929. He died in 1933.

When he arrived in Hell, he possessed raw power which was never before seen in a human soul and trampled powerful demons who had been in charge for centuries. He broadcasted this carnage on the radio for everyone to hear, and thus earned the nickname the "Radio Demon".

Charlie
Alastor assists Charlie with her endeavors; it's currently unclear what their relationship is. They have a similar sense of humor.

According to Vivziepop in her stream, Alastor thinks Charlie is funny, the same way how his earlier version thought of Mimzy, and he likes talking to her. When asked to give his unfiltered opinion of Charlie, he responds by saying he personally likes her smile and positive attitude. In his reprise, he tells her that he thinks she's 'one of a kind' as well as a 'charming demon belle.'

Angel Dust
Angel is very much unaware of Alastor's reputation. While taken aback a bit by Angel's offer for a blowjob, Alastor swiftly turns him down.

Vaggie
Vaggie is well aware of Alastor's reputation, upon Charlie first warning her the "Radio Demon" was at the door she insisted she shouldn't let him in. After Alastor lets himself in anyway Vaggie is determined not to let him hurt anyone with affiliations to the Hotel, referring to him as a "pompous, cheesy, talk-show shitlord" and threatening him at spear-point. She is distrustful of Alastor's intentions and exacerbated as Alastor continuously infuriates her with patronizing remarks and gestures for fun.

Husk
Alastor and Husk are acquainted with one another. They have worked with each other in the past, as shown in Alastor's backstory and Husk's dialogue. Little is known about what they did together, though Husk reacts with animosity upon realizing Alastor summoned him back for one of his endeavors, indicating he doesn't like getting pulled into Alastor's schemes. Also, despite Alastor's power and reputation, Husk doesn't seem to be afraid of him at all.

Rosie
Alastor has a connection with Rosie, but it has yet to be revealed what.

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

Mimzy
Alastor has yet to interact with Mimzy in the show.

In early development, however, they were good friends.

Niffty
Alastor and Niffty are acquainted with each other, as shown in the pilot. When asked if Alastor and Niffty knew each other before the hotel and what relationship they have, Vivziepop said that she can't really get into it a lot.

Lucifer
Alastor has yet to interact with Lucifer, at least on-screen. In the pilot, when looking at the royal family portrait, Alastor seemed to recognize Lucifer.

When asked what would happen if they met, Vivziepop stated Alastor would kind of like Lucifer; more specifically, Alastor would like Willy Wonka because he's a jerk, and Lucifer has a lot in common with Willy. Vivziepop and Dave also said that Alastor in no way would be afraid of Lucifer; they respect each other, and there's mutual respect going on between them.

Sir Pentious
Sir Pentious claims to have had a battle with Alastor prior to the event of the pilot episode. Alastor, however, claims to not remember any of it.

He brutalized Pentious when he attempted to attack the hotel.

 * His microphone is voiced by Dave Capdevielle, as Dave himself confirmed it on Ashley Nichols's HAZBIN HOTEL Animation Pt. 1 Ft. Dave Capdevielle and Micheal Kovach stream video and said that Alastor's microphone would have two lines in That's Entertainment.

 * The red markings on the soles of his shoes resemble deer tracks.
 * When asked whether or not Alastor is afraid of dogs, Vivziepop stated that she doesn't think he's afraid of dogs anymore, but he does still dislike them.
 * Viv mentioned in her Vivzie Stream #7 live stream that when she made Alastor, when he used to be just the deer, he was afraid of dogs. And it's kind of for her that now he's no longer afraid of dogs, he just doesn't like them. And Viv also said that he doesn't like them because of the backstory reason that she can't get into, but she did confirm that it does have to do with how he died.
 * When asked what Alastor's powers are, Vivziepop said that Alastor's powers are a lot of things that she can't even really say. She also said that she doesn't know all of Alastor's powers cause he's a secret.
 * According to Vivziepop, Alastor is a character that kind of keeps a lot of what he can do under wraps because he likes being unpredictable so it's one of those things where she feels like he sometimes will feign the inability to do something that he can actually do for a few reasons.

 * According to Viv, Alastor is not the kind of killer that follows or chases people, because he has a weird ethical code against that.

Although his casual remark of "so many orphans" during the pilot, "That's Entertainment", may seem to suggest he enjoys seeing them suffer.
