Alastor, the "Radio Demon" from Hazbin Hotel, is a charismatic, sadistic, and manipulative overlord with a permanent smile, often seen in a 1930s suit, possessing deer-like features (antlers, hooves) in his demon form, and wielding powerful shadow/voodoo magic, reality-warping, and demon summoning, all while hiding a secret deal that binds him, all stemming from a past as a radio host and serial killer in New Orleans.
