Alastor, also known as The Radio Demon, is a sinner demon and one of the many powerful Overlords of Hell. He is one of the main protagonists of Hazbin Hotel.

He is the wickedly charismatic demon who has offered to assist Charlie Morningstar in her endeavors, albeit for his own amusement.

Before being condemned to Hell, Alastor used to be a radio host in New Orleans who acted as a sadistic serial killer at night until he was shot by a hunter when he was mistaken for a deer.
