Alastor, aka The Radio Demon, is one of the many Overlords of Hell. Alastor stands out from many of the more chaotic residents of hell for his well-maintained amiable persona. He gives the first impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. Alastor's 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 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 conduct. His smiling is also a show of power and dominance, and miserable people are seen by him as weak. Alastor has an odd sense of morality, which is described as "not normal", and has been noted to be quite sadistic, even cannibalistic. He is noted to be narcissistic, not seeing many people quite up to his level. However, that does not make him reckless. Despite being extremely powerful, Alastor 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. Despite everything, Alastor does genuinely seem to want to help Charlie run the Happy Hotel, albeit for his amusement, and hopes for its failure over siding with her idealism. Alastor also dismisses the idea that redemption is possible as laughable. He views the whole endeavor as a fun distraction from his decades of boredom.
