(セーラーマーキュリー, Sērā Mākyurī
?) is one of the central characters in the Sailor Moon
metaseries. Her real name is Ami Mizuno
(水野 亜美, Mizuno Ami
?, or Amy
in the English versions), a genius schoolgirl who can transform into one of the series' specialized heroines, the Sailor Senshi.
Sailor Mercury is the first member of the Sailor Team to be discovered by Sailor Moon, and serves as the "brains" of the group. Her powers are associated with phases of water, and she can use her supercomputer to quickly analyze a foe in battle.
Aside from the main body of the Sailor Moon
series, Ami features in her own short story in the manga, called "Ami's First Love." Originally published in Volume 14 of the manga, this was the only one of three "Exam Battle" stories to be made into a "Special" for the anime series. In addition, a number of image songs featuring Ami's character have been released, including the contents of three different 3-inch CD singles.
