Amy's first identity is herself. *What a stupid way to put that!* Anyway, this is how she was reborn on earth, as Amy Anderson, the brains of every school.
Sailor Mercury is the non-evolved form of the soldier of Mercury. She has a supercomputer which tells her where the weak spot of the enemy is. She mostly has defensive attacks, and is physically the weakest of the senshi. She shouts "Mercury Power!" in the 1st season to transform, and "Mercury Star Power!" in the 2nd and 3rd seasons.
Super Sailor Mercury is the evolved and final form of Mercury. She has more aggressive attacks, but is still the weakest of them all. She shouts "Mercury Crystal Power, make up!" [Japanese Only] to become a super sailor.
Princess Amy, the princess of Mercury, was a princess in the Silver Millenium, and will be in Crystal Tokyo. In Sailor Moon SuperS, every scout was revealed to be princesses of their own respective planets as well as part of Serena's court.
