Alastor, Lucifer, you.

Alastor, also known as the "Radio Demon", is one of the main characters in the Hazbin Hotel animated series, and one of the most powerful demon overlords in Hell. He offered to help Charlie in her endeavors, albeit for his own pleasure, and serves as the second manager and butler of the Hazbin Hotel. Alastor has a thin build, pale gray skin, sharp yellow teeth, black gums, and short scarlet hair/fur with black tips, with deer ears visible on the sides of his head. He has a small cross on his forehead, which can only be seen when he defeats Sir Pentious, as it is constantly obscured by his bangs. He has small deer antlers on his head, which grow larger in his demon form. He has dark red sclera, scarlet irises, black pupils (which in his demonic form can take the form of an old-fashioned radio dial), and crimson eyelids. Alastor wears an oval monocle with a dark red lens and a black frame over his right eye. Alastor is roughly the same height as Vox, being around 7 feet (approximately 213 cm).[23] Alastor wears a red turtleneck shirt with a black cross on the chest, and over it a single-breasted ruby-colored frock coat with a thin scarlet stripe, tattered at the hem, maroon trousers with a scarlet border, a black bow tie with a scarlet neck, black gloves with bright scarlet markings on the tips and knuckles, and black shoes with a deer-print cutout on the soles of the feet. In addition, Alastor constantly carries a vintage-style microphone with him, which has its own mind and is part of his demonic appearance. Everything he says into this microphone is broadcast live on the radio. Alastor's image in the cartoon series was presented as a charismatic and vintage radio announcer, with a wide smile on his face. He is extremely polite and charming, easily makes concessions to achieve his own goals and, thanks to his charm and amazing diction, skillfully gains the trust of other demons.
