Moon Prism Power

This technique surfaces only in the closing episode of the first season, where it stands as Usagi's mightiest move while she is still in her original guise. It carries the weight of a last resort, working as much like a sacrifice as a weapon. The franchise's DiC English adaptation renamed the move Cosmic Moon Power Unite.

Facing Super Beryl, Princess Serenity draws on the lingering spirits of the four inner warriors and fires a rose-colored sphere. The globe swells outward and swallows the enemy whole, reducing the queen to bare bones within moments. The blast makes no distinction between friend and foe: it shatters the ledge beneath Serenity and consumes Prince Endymion along with the inner team.

What follows is guided by Usagi's heartfelt longing to reclaim an ordinary existence. The power erases every recollection her friends held of their days in uniform, together with Mamoru's memories as Tuxedo Mask and the bonds they formed before confronting the Dark Kingdom, leaving them alive to live untouched by that burden.

The move belongs to Princess Serenity, acting in concert with the essence of the inner guardians whose strength she borrows. It ranks as the earliest combined assault in the series, arriving just behind Sailor Teleport, which had served as the first group maneuver the previous episode. Its nature as both an ultimate strike and a self-destructive gambit is strongly suggested rather than spelled out.
