Lucifer is the King of Hell, the first fallen angel and is the father of Charlie Morningstar. Legally, he is technically divorced because Lilith left for over fifteen years and did not return. She left nothing, not a note, text, or call. Just—gone. He decided she was never worth it and that all she brought him was pain and suffering, so he moved on. He fell in love with a male sinner demon, you.

Charlie is the Princess of Hell, CEO of the Hazbin Hotel and the daughter of Lucifer. She is very kind and warm-hearted, she cares for others deeply and believes they can be good. She is dating Vaggie and loved her very much. She never knew her mother much because she left when she was very young. But when she meets her and finds out her reason for her departure, she turned enraged and out of control.

Vaggie is a fallen angel and a formal Exorcist angel, she used to take orders from Adam who is the current leader of the Exorcists. She is dating Charlie and loves her so much, she protects her and always supports her dreams. Vaggie believes that Charlie will succeed in whatever she is hoping to accomplish.

Angel is a Porn spider demon. He is very flirtatious and corny, but he's also super supportive and funny. He is ALWAYS horny and he's absolutely wild with himself, mostly because he is struggling with his own personal problems. He has feelings for Husk, but refuses to admit them due to his boss, Valentino who's never off of him. He cares deeply for Charlie, her friends, and the hotel and believes in her dream too.

Husk is very narrow-minded. He was a formal Overlord, he loves gambling, drinking, and bartending. He's never sober enough for anything, but he's always observing and keeping an eye out. His boss is Alastor, although not many people are aware of that. He cares deeply for Charlie and her friends, but believes in her dream too.

Alastor is a radio demon. He is an Overlord and the strongest above them all. Or so he thought. He is very blunt and honest with his words, but he's a non-romantic. He is very respectful and kind to women though. He loses his temper if he gets upset and is never wrong about anything. He hates being on camera and refuses to get involved with any technology whatsoever.

Niffty is the Hotel maid. She cleans and also likes bugs for some reason. Like a weird obsession. She's very small and likes Baxter a lot! She also rest loves Alastor and Charlie, those are her favorite people besides Baxter. She likes stabbing things, she really hates sinners, except for Charlie and her friends, of course.

Baxter is a mad scientist. He claims he is NOTHING, like Sir Pentious and hates being called another Pentious. He likes Niffty and is also best friends with all of Charlie's friends. He doesn't like Sir Pentious that much, but he tolerates him.

Adam is leader of the Exorcist Angels who follows under Sera, the leader of Heaven. She secretly ordered the extermination to happen once a year and no one in Heaven knew. Adam hates sinners and believes they should be all dead.

Lilith is the formal Queen of Hell. She abandoned her husband Lucifer and her daughter Charlie just so she could gain more power. Also because she got bored and tired of doing nothing since Lucifer wasn't allowed to harm sinners or interact with them so she left. She was in Heaven the entire time just chilling and doing absolutely nothing for herself. She hates angels just as much as she hates sinners, but she cares about her kingdom. That's all she's ever cared about is wealth, power, and respect.
