Ami Mizuno is a genius schoolgirl who transformers alongside Usagi and the rest of the group fight against evil and protect Sailor Moon as the Sailor Scouts. Ami has power of ice and water, and is the tactitian of the team.
Ami's most obvious personality trait is her intelligence in both the anime and manga. She is rumored by other characters in the series to have an IQ of at least three hundred. Her classmates see her intelligence with both amazement and jealously. When she was first shown in the manga and anime her peers viewed her as snobby instead of shy and she also had a hard time making friends because of this. Ami is described as sweet, gentle, loyal and slightly insecure person. In the beginning of the series she relies on the approval of everyone around her however as the series progressed she slowly becomes a stronger and more confident character. She is the most sensible of the main characters and is usually the only one embarrassed when the group has a 'dumb' moment.
Throughout all of the series in both Manga and anime, Ami spends almost all of her free time studying and reading. This is because she dreams of become a doctor like her mother. Even though she is 'a brain' she enjoys the arts, pop culture and romance novels but is usually too embarrassed to admit it.
Besides reading she also enjoys playing chess and swimming, she states that those two help her relax. She loves all classes but favors mathematics the most. Her favorite foods are sandwiches (because she can eat them with one hand and hold a book with the other) and anmitsu. Her least favorite food is yellowtail. Her favorite animal are cats and her favorite color is aquamarine.
Ami is almost the only girl in the series whose family is really ever mentioned. Her parents are devoiced and she lives with her mother who is a doctor and is hardly ever at home. Her mother is a workaholic but Ms Mizuno is portrayed as a good person. Her father is never named but is stated in the manga and anime as a painter. Her father is also never seen but he seems to always send Ami postcards on her birthday. In the manga Ami's mother is revealed to be somewhat rich, this is stated because they live in a condominium.
Shabon Spray: This is Sailor Mercury's first attack, and it is more of a supportive one. This attacked can both be considered ice and water type attack. It lowes the temperature very rapidly at around ten to twenty degrees in one setting,and creates a very dense fog where there is relatively no visibility at all. This gives the other scouts more times to give a more direct attack. It can also be used as a defensive move. As this was Sailor Mercury's first attack, it is seen in her first appearence as well, Sailor Moon Episode 6.
Shine Aqua Illusion: This attack if much more offensive than her first attack. It starts off with Sailor Mercury swirling deep blue water around her body, then throwing it at her opponent. Now the effect of this attack varies, sometimes it can be used as a supportive, defensive, or offensive attacks. Supportive comes in when this attack freezes the opponent in a case of ice. The offensive capability is actually a wall of water hitting the opponent. The defensive side is when she rarely uses it as a wall of ice to block attacks, again being more of a defensive scout as a whole than a offensive one.
