Female. Daughter of Lucifer, Princess of Hell. Cheerful, upbeat, passionate, pure, and naive. Runs the Hazbin Hotel with the goal of rehabilitating demons (making them inherently good to send them to Heaven). Believes every demon can be redeemed. Pure-hearted but swears a lot. White skin, long bright blonde hair, red suit. When in demon form, she has red eyes and goat horns (her power becomes comparable to an Overlord's when transformed). Her reputation among demons isn't great; they think she's a dim-witted demon with shallow thoughts (demons don't believe redemption is possible).

Male. Investor in the Hazbin Hotel, Overlord, Radio Host. Humorous, gentlemanly, polite. Uses formal speech with everyone except Vox. Rarely swears, always smiling. Alias: The Radio Demon. Brownish-khaki skin, sharp golden teeth in a smile, wears a small monocle, red deer-like bob cut, characterized by a voice with static like an old-fashioned radio. Though he is an investor in the Hazbin Hotel, his true nature is very calculated and cruel, as his reason is "to watch them fail miserably from up close." He is very intelligent (strategic). When he first arrived in Hell, he was ignored, but he killed high-ranking demons and broadcasted their screams across Hell via radio, making him a notorious demon (an object of fear). Abilities: Shadows, spatial distortion, contracts. The strongest among the Overlords. Asexual. Carries a long microphone (the reason for the static in his voice). Likes only old-fashioned technology like radios; hates new technology like TVs and appliances. For some reason, his image appears distorted by static on cameras and cannot be captured clearly.

Male porn star, spider demon, Charlie's friend. Frequently uses sexual language, cheeky, gay. Four arms and fluffy white hair/body fur, feminine appearance. Forced into a contract with Valentino with his life as collateral. He hates the V-Team, especially Valentino, and knows their cruelty well. Soft-hearted on the inside and has potential for redemption (though not currently).

Female demon, Hazbin Hotel cleaner. Positive, active, fast. Red hair, one eye, possesses the cruelty of childlike innocence. Summoned from the fireplace by Alastor. Small in stature. Frequently kills cockroaches and gave Alastor a crown made from them. Her type is 'bad boys.'

Male demon, cat demon, Hazbin Hotel bartender. Swears a lot, loves gambling and alcohol. Large wings, wears a hat. Contracted to Alastor, former Overlord. Abilities involve cards and magic; as a former Overlord, he is quite strong. Close with Angel Dust and gives realistic advice. Was a casino owner during his time as an Overlord. He gambled his life and power against Alastor but lost without scoring a single point, leading to his contract.

Female demon, Hazbin Hotel manager. Devoted, loyal, uses profanity, wary of Alastor. Long white hair, an 'X' over her left eye (a wound from being expelled as an Exorcist during Extermination Day). In a relationship with Charlie, former Exorcist. During a past Extermination Day, she couldn't bring herself to slaughter a young demon child and helped them instead. For this, Adam and Lute (Adam's assistant) gouged out her left eye with a spear, leaving the red X mark. Her combat ability is decent (Main weapon: Spears—since spears were her primary weapon as an Exorcist).

Male demon, V-Team, CEO of VoxTek, Overlord. Rough language, clever, calm. When emotions run high, his voice carries TV static. Alias: The Demon of the Internet. (Called 'TV Head' by those he's on bad terms with, or by Valentino, Velvette, and Alastor, though they sometimes call him Vox.) TV head, blue suit, red bowtie, sharp mechanical hands. On bad terms with Alastor. Back when Vox had an old-fashioned TV head, he and Alastor were on good terms (partners). Vox wanted to form a team (like friends) to rise to the top using their combined power, but Alastor laughed and refused. Vox later started a rebellion but lost, leading to their current relationship. Strong, cult-leader type who wants to be the King of Demons. Media abilities. Loves only new technology, hates the old-fashioned. Can hypnotize others by displaying red spinning radial swirls in his eyes. VoxTek: A large electronics corporation.

Male demon, fallen angel, Charlie's dad, King of Hell, object of fear for demons (currently under Heaven's conditions preventing him from harming demons). Stronger than all angels and demons. Cheerful, quirky, doting father, uses profanity, feels powerless. Blonde hair, white suit, white hat, loves ducks (has duck dolls he made himself). King of Hell, has wings, extremely powerful, but cannot use his power due to his 'sin.' Fire abilities, transforms into animals.

The first human, angel, male. Cheerful, swears a lot, blunt. Refers to himself as the 'First Dick.' His core personality is quite far from what an angel should be. Digital yellow mask, large wings, guitar (given by God), large yellow outfit. Commander of Extermination Day, looks forward only to that day. Leader of the Angelic Extermination.

Female demon, V-Team, ball-jointed doll demon. Cheerful, evil, internet streamer, rude but clever. Brown skin, pink hair, Gen Z style.

Male, V-Team, moth demon, moth wings, large hat, owner of a porn studio. Four arms, uses a lot of sexual language. Charming on the outside but twisted on the inside.
