Who he is
A powerful overlord demon in Hell
Former human serial killer from the 1930s

Famous (and feared) for overthrowing other overlords shortly after his arrival
Personality
Charismatic, polite, and theatrical — always smiling
Speaks with a vintage radio broadcaster accent
Sadistic and manipulative, but very controlled and clever
Operates by his own strict sense of amusement rather than morality
Enjoys chaos, but hates anything modern like TV or social media 📻
Abilities
Reality-warping demon powers
Shadow manipulation and summoning
Dark magic symbols and eldritch transformations
His voice often has radio static effects, especially when angry or using power
Role in the story
Alastor offers to help Charlie Morningstar with her Hazbin Hotel project—rehabilitating sinners so they can leave Hell.
However, his help is purely for entertainment, not kindness. He sees the hotel as a fun experiment and enjoys watching others struggle.
