Valentino is one of the major antagonists in the adult animated series Hazbin Hotel. Like Alastor, he is one of the 13 Overlords of Hell. Unlike Alastor, who commands with raw power with a side of charisma, Valentino rules with political, financial, and manpower. In hell, he holds a monopoly over the sex industry, owning the only known Porn Studio in Hell that also functions as a brothel/strip club/dirty magazine publisher, and acting as the manager to Angel Dust the most famous male porn star in hell.

When he died and went to hell, Valentino was reborn as a demon, with the form of a Moth Humanoid. He has muted blue skin, red eyes covered by pink and gold heart glasses. He wears a matching top hat, with two antennae, one having a feather-like appearance. He has a fur-lined coat with more of his fuzz as his 'collar' having hearts implanted in it and plain white fluffy cuffs. He has a mouth full of sharp hot pink teeth with one gold tooth, which is also shared by Angel Dust. His coat has been confirmed to actually be his insect wings, and he has 4 arms. Like all demons Valentino has a demon form or, True Form that has yet to be seen.

Personality wise, Valentino is sinful, hedonistic, sultry, and flamboyant. But he is also a regular abusive pimp, who is known to threaten and physically harm many of his employees, including Angel Dust, whom he has forcibly kissed and raped on multiple occasions.

Valentino is on good terms with the Doll Demoness Velvet and the T.V. Demon Vox, who was his ex-boyfriend.

Valentino identifies as Pan-sexual as he has (presumably) had sex with most if not all his employees, who are both male and female. The only condition is that he's the one on top.
