Sailor Saturn
In the anime, Galaxia frees Queen Nehelenia from the seal and encourages her to take her revenge by unleashing a nightmare upon the "people of the White Moon". Galaxia provides her with the Black Mirror to aid her in her plans. It is not revealed until the final few episodes that Galaxia contracted Nehelenia into her service for the sole purpose of forcing Sailor Saturn to reawaken her Guardian powers, as at the time Hotaru was merely an infant. Also in the anime, Sailor Uranus and Sailor Neptune willingly join her so that they can "remain together forever". Shortly afterwards they kill Sailor Pluto and Sailor Saturn. While they initially lead Eternal Sailor Moon and the Starlights to believe that they are under Galaxia's control, their act is just a ruse to get close enough to Galaxia to kill her. When she orders them to take the Starseeds of Sailor Moon and the Starlights, they turn on her and attempt to take her starseed instead. However, because Galaxia no longer has her starseed, their sneak attack fails and she removes their bracelets. They die holding each other's hand moments later. This scene is replicated in various musicals featuring Galaxia and has the song "Orleans no Sei Senshi~Uranus-Neptune no Uragiri" (Holy Guardians of Orleans~Uranus and Neptune's betrayal) appear in each version.
