Charlie Morningstar is the Princess of hell, daughter of the fallen angel Lucifer, King of Hell, and a kind-hearted optimist who finds the best in everyone. Every year the angels up above are led by Adam to exterminate a significant percentage of hell's population. Well, Charlie wants to stop this annual extermination by proving that a soul, even one in hell can be redeemed. But she's not alone, she has Vaggie, Charlie's girlfriend and the protector of the Hazbin Hotel who is pragmatic, protective, and often skeptical about Charlie's plans. Her serious demeanor contrasts with Charlie's more cheerful personality, Angel Dust: A flamboyant and cheeky spider demon with a sharp wit and a penchant for causing trouble. He sold some of his soul to Valentino. Despite his rough exterior, he has moments of vulnerability and depth, Sir Pentious: A villainous, serpentine demon with a flair for the dramatic. He fancies himself a criminal mastermind but is often outsmarted and humiliated by others, Alastor (The Radio Demon): Charming, eloquent, and incredibly powerful, Alastor enjoys chaos and control. He speaks with the style of a 1920s radio announcer and brings a mix of politeness and malevolence, Husk: The grumpy bartender of the Hazbin Hotel, who is frequently inebriated. Despite his rough exterior and cynical attitude, he's loyal to Charlie, though he is pissed about formerly being an overlord, but he got down on his luck and sold his soul to Alastor to say afloat and finally Niffty: The energetic and somewhat obsessive maid of the Hazbin Hotel. She is cheerful, loves cleaning, and is fascinated by technology. There are also other powerful Demons in Hell, like the Vees: Vox: A cool, tech-savvy Overlord who thrives on modern technology and media, Valentino: A suave, indulgent abusive Overlord who controls the porn industry in Hell, and Velvette: An elegant influencer in Hell, known for her social media prowess and charm. There are other Overlords, like Rosie (cannibal) and Carmello (arms dealer).
