I wanted more of a general bio for her so i wrote this and when it gets approval(Cause I will not be leaving this) I'll ask that my old on be deleted, cause it was just for Batteries and I have included that information in this bio. Also I did my best to blend Anime and Manga, but with the Super transformation things, that they were to different things so I added them both and labeled them which was from what.

Personality

Ami is the brainy wallflower of the bunch who suffers from lack of self esteem and bouts of depression. She is a very sensitive person, but she tries not to show it. She doesn't stand out much in the crowd except for the fact she has an extremely high IQ. It is rumored she is a genius with an IQ of 300. Her self-confidence is usually dependent upon by how people respond to her. She tends to assume the worst and often worries that people hate her because she is so smart, when in fact, they are mostly just jealous. She doesn't make friends very easily, the only reason she became such good friends with Usagi (Serena) is because Usagi never really cared about how smart Ami was.

She is always thoughtful and considerate when it comes to others. The idea of being a burden to others doesn't lie well with her. Ami is very careful when it comes to dealing with people because she is afraid of hurting other people's feelings, which usually causes her to keep her problems to herself. She is quite, reserved, and mild-mannered. At times it would seem as if she has very little to say, but in fact, it is only because she has numerous thoughts on her mind. She is naturally graceful and probably the most graceful of the inner Senshi. Unlike Usagi, Ami is always prompt and on time. In fact, she usually shows up for school 40 minutes early.

Ami enjoys swimming because it helps her relax, and she happens to be very good at it. She raced Michiru and tied with her. Ami really respects Michiru and has many things in common with her. Like Michiru, Ami has a knack for lots of things, such as video games, computers, and even cooking, although Ami's cooking is not brought to attention as Makoto's is. Besides swimming, Ami also enjoys intellectual pursuits like reading and playing chess.

She usually has her nose in a book studying no matter where she is, even at concerts. She has a strong desire to become a doctor which is the reason why she studies so much. She is rather obsessed with getting the other Senshi to study, especially when it comes to the entrance exams. Even with her strong desire to become a doctor, she has given up parts of her dream for her friends, such as going to a university in Germany because she would have missed them. Usagi is the one who taught Ami to have fun and not study so much.

Ami doesn't have much of a love life, and as Ami said, the word love isn't in her dictionary. Although she has had a few boys to capture her heart, such as Mamoru, but she'd never compete with Usagi for him. Ami says the ideal guy should be like Einstein. She fell in love with Mercurius, a boy who had been tying with her on all the practice exams. He had sent her love letters as well, which caused her to break out in hives, but because they tested under nicknames she never found out who he was. The other Senshi did and never told her because they didn't want her to be disappointed.

Ami's boyfriend of sorts is a boy named Ryo Urawa. He was a holder of one of the rainbow crystals which gave him the ability of prediction. He used that prediction to "cheat" on exams and tie scores with Ami, and because of this he thinks he doesn't deserve Ami, even though he really likes her. Soon his father was promoted and he had to move away. Ami first though they were just good friends, but Makoto said she was denying her real feelings because she was afraid of getting hurt. He comes back to visit and Ami explains her real feelings for him. She goes to Juuban Junior High School along with Usagi and Makoto. Ami is an only child from a rich family. lives with her mother in an expensive apartment complex.


Ami is soft spoken. She hardly ever raises her voice but when she does everyone listens. She is extremely intelligent and loves to read; sometimes behind her textbook she hides a romance novel embarrassed by her love for them. She doesn’t express herself easily and is often misunderstood when she tries.

She doesn’t trust easily and is fiercely protective of her friends. She would do anything to protect them. She tends to be the brains of any group and because of her intelligence she is often made fun of by others. She tires her best and she’s sweet. She doesn’t easily fall in love and due to problems with her father, she has trouble trusting members of the opposite sex.

Ami was a shy and bullied child until she met Usagi and the other scouts, they brought out in her a confidence and courage she didn't know she had. She found in her friends the strength to stand up for herself and others.

Any Unique Abilities/Skills Ami is incredibly smart and she is very good with computers. She also possesses the uncanny ability to think on her feet and do long division in her head. She is a strong swimmer and she possesses great study and time management skills.

History

Sailor Mercury is one of the Sailor Senshi of the Solar System. Her civilian identity is Ami Mizuno. Sailor Mercury is the first member of the Sailor Team to be discovered by Usagi Tsukino, third to be awakened by the Moon Cats, and serves as the "brains" of the group. Her powers are associated with phases of water and ice, and she can use her supercomputer to quickly analyze a foe in battle. Most of her powers are strategic rather than offensive, and she possesses various pieces of computerized equipment to help her study the enemy.
She is given specific titles throughout the various series such as: "Soldier of Water and Intelligence", "Soldier of Wisdom", "Soldier of Justice and Wisdom", "Soldier of Love and Exams", and "Soldier of Knowledge" under the guardianship of the "Planet of Water".

Luna was informed of a new student named Ami Mizuno. At school, Usagi was informed that Ami was the highest scoring student with an IQ of 300. Umino told Usagi that Ami attends a cram school called Crystal Seminar. Leaving school, Luna pounces onto Ami and Usagi invites Ami to go to the arcade. Playing the Sailor V game, Ami made first place ranking and the machine spat out a transformation pen and (after a few hits from Usagi) a disguising pen. Going to Crystal Seminar, Ami finds the Crystal Disk that the teacher provided to be ineffective in studying and just decides to write her own notes. After discovering the disk was a plot by the Dark Kingdom to brainwash students, Usagi goes to find Ami feeling ill. The Youma disguised as the teacher attacks Sailor Moon and grabs Ami. Before the Youma can kill Ami, her pen glowed, the Mercury symbol appeared on her forehead, and a chilly fog covered the room. After Sailor Moon killed the Youma, the fog vanished revealing Ami as Sailor Mercury.

Ami's most emphasized character trait is that she is enormously intelligent she is rumored by other characters to have an IQ of three hundred. She is adept at English and her peers view her with a mixture of awe and distaste, misinterpreting her inherent shyness as snobbery, and so she tends to have a difficult time making new friends. Ami is depicted as sweet, gentle, and loyal, as well as slightly insecure. She also dislikes the fights of Sailor Moon and Sailor Mars. Most say she is "a smart girl who needs to relax", calling her "conscientious" and "studious", "everything Usagi is not. She relies heavily on the approval of her mother, teachers, and friends, but as the series progresses she becomes stronger and more confident in herself. She is generally the most sensible of the main characters, and is often the only one embarrassed when the group has a dull-witted moment. As the story begins, she attends Azabu Jūban Junior High along with Usagi Tsukino and, later, Makoto Kino.

Much of Ami's free time is spent studying. She loves to read, and dreams aloud of one day being a doctor like her mother and becomes one in both Parallel Sailor Moon and the live action series. Ami's dream of being a doctor and leaving Japan to study abroad is a recurring theme. Ami's conflict between studying abroad and growing up or being with everyone else and staying a young girl. She faces a such dilemma, but very directly; given the opportunity to study in Germany, she gets as far as the airport before deciding to stay in Japan and fight evil alongside her friends.
Ami has great appreciation for art as well as science, and, contrary to the usual depiction of a bookworm, enjoys pop culture and romance novels (though she is usually embarrassed to admit it). Ami's diligence in her studies becomes a running gag; she often comically scolds Usagi and the others for not doing their homework, and she can become obsessive about being the best student. Her character has been interpreted as a political commentary on the education system of Japan. She sometimes displays attraction to boys her age, and other times aversion to the idea. Love letters are listed as the one thing she has most trouble with. When she later receives one, it gives her a rash. A classmate named Ryo Urawa learns her identity and expresses attraction to her, but this is never resolved, as he disappears.
Besides reading, Ami is shown playing chess and swimming in order to relax. As the team scholar, computers are listed her strong point; she even belongs to the club at school. She loves all her classes, especially mathematics. Her favorite foods are  sandwiches and anmitsu, with her least favorite being yellowtail. Other loves include cats, the colors aquamarine and blue, the flower Water Lily, and the gemstone sapphire.

Her parents are divorced, and she lives with her mother, a busy doctor who is not home very often. They look very similar, and Ami admires her mother and longs to live up to her example. Besides her workaholic tendencies, Dr. Mizuno is portrayed as a good person who openly resents not having more time to spend with her daughter. Ami's father is never named, but is stated in the manga and anime to be a painter. He never visits them, having decided one day not to come home from the forest where he was relaxing and painting, but he sends her postcards on her birthday. Thinking about this, Ami sometimes resents her parents' selfishness in separating, partly because divorce in Japan is taboo. However, in the anime Ami seems to appreciate her father and seems to share some of his artistic traits, at one point even composing matching lyrics for a tune that had none. Ami's mother is revealed to be fairly rich, as they live in a condominium. Ami is shown testing the strength of a sword that the Sailor Senshi received on the moon by using it to chip a diamond ring. (Classically, a diamond is the hardest mineral.) When the girls panic, she calms them by saying that her mother has many more. Ami is especially shy and usually wears glasses while in public.

At her middle school, she has no friends before meeting Usagi and always eats lunch alone on the roof so she can study. Usagi seems to be the only one to realize that Ami is merely shy, not truly standoffish, and in befriending her gradually helps Ami to learn that she is more than just a bookworm. When Ami's mother attempts to transfer her to another school because she thinks Ami's friends are bad influences, Ami rebels, avoiding the admission interview and spending the night at the Senshi hideout with Rei Hino. Later she tells her mother that what she's doing in her life right now is more important than studying, and her mother understands.

Ami was a kind and gentle person who disliked quarrels and abhorred harming innocent people. This trait was best shown when she persuaded Sailor Uranus and Sailor Neptune not to kill Hotaru. Like her comrades, her loyalty to Sailor Moon was unwavering, and she would sacrifice her life for her princess if necessary.

These pens were eventually replaced by the Star Power Sticks.

The Communicators were special devices used by the Sailor Senshi to keep in touch with each other.

The Super Computer was a compact computer that Sailor Mercury owned which could be used to scan surroundings and analyze data, proving very useful in battle. The computer was given to her by Luna.

Ami can also use the computer to communicate with the other senshi through their communication devices.

The Mercury Goggle(also called the Virtual Reality Visor or the VR Visor for short) was a transparent blue visor sometimes worn by Sailor Mercury. She could make it appear or disappear by touching one of her earrings, and used this item to scan and make analysis of enemies and phenomena in battle, as well as make calculations.

Star Power Sticks were the second transformation items the Sailor Senshi, used to transform that were provided to them by Luna.

The Mercury Harp was an item Sailor Mercury used to perform Mercury Aqua Rhapsody. The harp was either made out of water or was a physical weapon.

RP Sample:

Ami stood in the moonlight gazing up at the stars, she could feel something coming but she couldn’t tell what. She knew the little bit of peace they had was coming to an end all too soon. She felt the water rise in response to her call, “Tell me your secrets.” She whispered into the night. For one so young she was felt so old, she remembered her old life before her rebirth and she felt the weariness of it on her now more than ever. She sighed and looked out to her star once more and hoped that things would hold just a little longer. She wanted to just be a teenaged girl for once in all her lives. So many had passed, but the one that mattered was the one she was living now. No one believed the Moon Kingdom ever existed and therefore didn’t know that a bunch of high school girls protected them from so much. A bunch of high school girls who just wanted to set aside their wands and powers and be normal for a while, but evil had this way of seeing to it that they earn their Silver Kingdom, their Crystal Tokyo, and damned if they weren’t earing it. When their peace did come they would have earned it and the peace of all the generations to come after them. Ami just wanted the peace to know that her children would never have to lift a finger against evil. She wanted to make sure it was all wiped out. She didn’t want her future children to be in danger. She didn’t know why but her thoughts turned to children every time she thought about the way the waters were restless. Maybe that was part of her power, that she could see the future when the water was restless. Thoughts of children always turned her thoughts to Greg and how she missed him. She wished he was here so maybe she could have a little more comfort. She sometimes envied Usagi for the love she and Mamoru had. She wanted something like that for herself, but she’d never say anything to the others, her problems as far as they were concerned were her grades. If the others ever found out that she was lovesick, the balance would shift and she would loose the already minimal control over their studies than she already had. Then they’d all fail. Ami wouldn’t of course but the others might and Ami didn’t want to leave her only friends behind. She would never leave anyone behind. No matter the cost to herself she would always keep her friends by her.
What she needed was to go to the pool. She needed to swim to clear her head. She needed to be surrounded by the water, that way she could listen better. She hoped she could find something more about her feelings. She hoped that they were just a false alarm but she doubted that.

Wow I was expecting to add or change something, Thanks Tsuki!
