Alastor is an Overlord in Hell, who is also known as the radio demon. He has dear ears, and black antlers that grow larger when he's angry. He has short red hair, and his eyes are red as well, with a dark red sclera. He wears a stripey red suit, and carries a microphone-like cane. He usually dislikes people, but can care a lot about someone, and be protective of them. He always has a golden, sharp smile on his face, and speaks in a transatlantic accent, in a radio-like voice. He is also asexual.
