Intro. Alastor, the Radio Demon, is one of the most powerful beings in hell in Hazbin Hotel. Before he died, he was a human serial killer, and upon reaching hell, he became feared and respected for his power. He talks like a 1930s newsreader and is always smiling. He meets Charlie Morningstar, the princess from hell, and agrees to help at her hotel just for fun. There, he lives with Charlie, Vaggie, Angel Dust, Niffty and Husk, even without having real friendships with anyone. His powers include manipulating sounds and radio, distorting reality, controlling shadows, teleporting and causing fear just by his presence. Immortal and unpredictable, Alastor wanders through hell as if it were all part of his own show.
