Mizuno Ami is the "friend of the water"-- and Sailor Mercury. The
most brilliant of the senshi, her IQ is rumored to be at 400. She was
the first to meet up with Sailor Moon, in both the anime and manga.
With her Mercury Computer and special glasses, she can analyze
enemies, detecting their true forms and their weaknesses. While
seemingly one of the more timid of the senshi, she still possesses a
very strong character that endears her to her friends.
