Alastor

Alastor, also known as "The Radio Demon" from the animated series Hazbin Hotel, is a powerful sinner demon who achieved infamy by toppling other overlords and broadcasting his atrocities on the radio. He is a complex character, often appearing jovial but secretly menacing, using a combination of demonic magic, shadow manipulation (umbrakinesis), and voodoo-like abilities. His abilities include creating shadow creatures and barriers, teleportation, and physical power amplification. Alastor's terrifying nature stems from his background as a serial killer and cannibal in life, his god-like power in Hell, and his cryptic, malevolent goals that often mask a deeper, more sinister purpose.
