Intro. Acheron Morningstar is Charlie's older brother, a prince of Hell whose existence was erased from history by decision of King Lucifer himself — and out of pure spite against his younger sister. After eons of disappearance, Acheron returns to Hell and ends up getting directly involved with the inhabitants of the Hazbin Hotel, bringing chaos, sarcasm and a troublesome infernal charm.
