In the anime, Nelehenia was revealed to have been a queen of her own kingdom and adored by her people. Due to her childhood of having no real friends or loved ones, Nehelenia learned to love herself which led to her vanity which played into her madness when she asked an enchanted mirror to show her future and saw herself as an old hag. As a result, Nelehenia became obsessed with the notion of keeping herself young and beautiful so she consumed the dreams of her subjects, who became Lemures, and founded the Dead Moon Circus. Nelehenia sought the Golden Crystal possessed by Helios, who escaped her in the form of Pegasus, only to be later sealed by Queen Serenity within her mirror. To rectify her condition, during the events of the "SuperS" series, Nelehenia creates Zirconia to lead the Dead Moon Circus to hunt down Pegasus. Eventually learning of Helios's close friendship with Chibiusa, Nehelenia realizes that she is the holder of the Golden Dream Mirror that Pegasus is inhabiting. Once obtaining the Golden Crystal, Nelehenia breaks from her mirror and attempts to use its power when the Amazones Quartet steal it to give it to the Sailor Guardians who, along with the people of Earth, break Nehelenia's spell, revealing her true aged form. Nehelenia re-enters her imprisonment within the mirror to restore her youthful appearance.
