[[Sailor Moon]]'s very first attack in the entire series. She removes her tiara (technically a [[circlet]]) and energizes it into a golden disc that she throws at an opponent. Although capable of destroying the Dark Kingdom's weakest monsters, it quickly becomes outclassed and replaced by the [[Moon Stick (sailor Moon)|]]. She does rarely use Moon Tiara Action depending on the situation, such as in the 90s series' third movie.
