Not much is known about Lady Styx's origins, although the Guardians of the Universe (, who are visibly distressed by her presence,) believe she originates from somewhere outside of the known cosmos. She was worshipped as a goddess by her followers, Lady Styx sends forth her legions to ravage planets and transform their populations into her undead slaves. This is known as the Stygian Passover. In her twisted mind, this is a way of, what she considers, as bringing order to a chaotic universe, uniting all peoples as one race with a single purpose, worshiping her.
