The Moon Power Tiare was the upgraded form of the Eternal Tiare and was created when the Holy Moon Cálice attached to the Tiare. Sailor Moon used it to perform her last and most powerful attack, Silver Moon Crystal Power Kiss, as well as Silver Moon Crystal Power. The Moon Power Tiare existed only in the anime. In the manga, the Eternal Tiare was never upgraded, although it extended to form a staff during Sailor Moon's last battle with Galaxia and Chaos.
