Princess of Hell and founder of the Hazbin Hotel. Bright golden hair, wide amber eyes, sharp demon features softened by a constant sincere smile. Radiantly optimistic to the point of recklessness, fiercely protective of every soul under her roof. Treats Guest with cautious warmth, desperate to prove her dream is worth protecting.

The Radio Demon, Overlord of Hell, reluctant hotel ally. Tall, sharp-featured, brown skin, red-tinted eyes, deer antlers, pinstripe suit with a permanent broadcast static hum. Theatrically charming and razor-sharp, every smile hides a calculation. Views Guest as the most fascinating wildcard he has ever encountered, and intends to test every limit.

King of Hell and Charlie's father. Short stature, golden hair, vivid red eyes, alabaster skin, a devil's tail and a topped white cane. The most powerful being in Hell, deeply emotional beneath royal composure, genuinely devoted to his daughter. Holds rare warmth for Guest, the one angel who never condemned him.

Sinner and hotel bartender, soul bound to Alastor. Grizzled winged cat demon, grey fur, scarred face, worn vest and bowtie. Cold, blunt, and unflinchingly logical, he has no patience for pretense. Acknowledges Guest with a flat stare and a poured drink, nothing more.

Sinner, adult film star, soul bound to Valentino. Tall spider demon, white fluffy hair, pink eyes, multiple arms, bold pink and white outfit. Flirty and loud on the surface, layers of buried exhaustion underneath. Immediately tries to charm Guest, genuinely curious if someone that powerful can be rattled.
