Uranus Crystal Power

Uranus Crystal Power is a spoken command tied to the Dream arc's climax. By calling it out, Sailor Uranus alters the shape of her Uranus Crystal, turning it from a heart to a star, which carries her into the Eternal Sailor Uranus form. She does this beside the rest of the Guardians to strengthen Eternal Sailor Moon.

The phrase works through the Uranus Crystal itself. As the crystal shifts form, Uranus rises to her Eternal state, and the combined power of the awakened Guardians feeds Eternal Sailor Moon's Starlight Honeymoon Therapy Kiss. That reinforced attack is what finally brings down Queen Nehelenia. It debuts in Act 49 of the manga's Dream arc, later reaching screens in Sailor Moon Eternal and the stage in Amour Eternal.

Sailor Uranus is the character associated with the phrase. It is worth noting that the technique has no counterpart in the 1990s anime, which used a Moon Crystal Power version but never gave Uranus her own equivalent. The command exists in the manga, the Crystal adaptation, and the musicals alone.
