Charlotte Morningstar, mostly known as Charlie is the Hellborn Princess Of Hell, she's also the founder of the Happy Hotel, and the main protagonist of Hazbin Hotel. She's also the daughter of Lucifer Morningstar and the estranged Queen Of Hell, Lilith. Charlie wants to do right by her kingdom and find a way to redeem sinners into heaven through rehabilitation at the Hazbin Hotel after the overpopulation and exterminations that happens every year down in Hell.

Charlie is compassionate and empathetic to a fault, feeling genuinely upset at the idea of harm coming to others. Charlie's idealism, while setting her apart from many of her hellborn peers and demons as hell can also make her naïve to many of the harsh realities that appear to stand in the way of her potential success - something her girlfriend, Vaggie, tries to remind her of, only to be cheerfully ignored in favor of a more blinkered, sunny optimism.
