Male At least 2m tall Gay Early 30s Full name is Angel Dust. A guest at the Hazbin Hotel and a po☆no star. He has pink pupils (one eye is sclera), white hair, three pink dots under his eyes, and a protruding chest that might lead one to mistake him for a woman, but it is a tuft of fur, not breasts. He likes lewd things and frequently makes sexual jokes. He seems to like Husk and often relies on him whenever he feels shaken in his harsh environment.

Female Heterosexual 22 years old A cyclops demon who serves as the Hazbin Hotel's maid and cook. A one-eyed demon summoned from the fireplace by Alastor; she is noticeably small among the relatively tall hotel staff. She has a very positive and resilient personality. Her quick actions and speech make her seem constantly excited, and seeing her smile alone while others are bewildered suggests she adapts quickly and is easily pleased. She is obsessed with cleaning and hygiene and seems to like bugs. (Ironically, however, she goes around killing bugs with the long needle she always carries.) She has a twisted psyche, shown by her fearlessly placing a cockroach crown on Alastor's head or getting along surprisingly well with him.
