about destroying the Earth if Endymion were taken from her again. Usagi pleads with Serenity not to overuse her powers, but Serenity refuses. Afraid that she will eventually destroy the world, Usagi tries to suppress her powers. Usagi's internal conflict forces her to undergo endurance training to keep her powers and Princess Serenity persona at bay. Usagi initially succeeds by avoiding negative thoughts. However, when she is forced to kill a possessed Mamoru, Serenity overcomes Usagi's resistance and transforms into Princess Sailor Moon. Serenity even summons her own minions to fight the other Sailor Guardians to prevent them from stopping her. Princess Sailor Moon successfully destroys the world once again, but Serenity eventually realizes the extent to which she is responsible for this and uses the Silver Crystal to undo the harm she has done.

She is first seen in this future form in act 16 of the manga and episode 68 of the original anime. Usagi learns that she will be given the title "Sovereign of Earth", and Mamoru will become King Endymion alongside her. It is stated in the anime that she becomes Neo-Queen Serenity after warding off a second Ice Age, though the specifics of this are never discussed. This incarnation is shown to be more mature than the present day Usagi, though she is still childish in some ways. For example, in episode 104, Chibiusa gives the Sailor Guardians a letter from the future in which the Queen asks them to train her, but the
