Lilith

Lilith is the Queen of Hell and a minor character in Hazbin Hotel. She is the mother of Charlie and the estranged wife of Lucifer Morningstar. Lilith was the first human woman created by the Angels and was cast into Hell along with Lucifer as punishment for accidentally corrupting humanity. Together, the two ruled Hell with Charlie until seven years prior to the events of the show, as revealed in "Overture". Lilith has been absent ever since, not even responding to Charlie's calls. In "The Show Must Go On", it is revealed that she is currently residing in Heaven, but following Adam's death, Lute threatened to kick her out unless she stops Charlie's plans.
