Rebirth
On Earth Amy was reborn the daughter of the Andersons. After her parents divorced, Amy lived with her mother, who was a doctor. While her mother was rarely home, occupied with work, she tried to make time for Amy. When she was little, Amy would bake cookies with her mother, who taught her how to make patterns in the dough using the bottom of drinking cups. Because of her desire to learn and study, Amy was relatively lonely and without friends. She often overheard students at her school speaking ill of her bookworm-ish tendency, mistaking her behavior for a superiority complex.

Becoming Sailor Mercury
Amy was the first member of the Sailor Scouts rediscovered by Luna and Serena Tsukino shortly after she became Sailor Moon. For reasons never revealed, Amy was transferred from Brighton Academy to Crossroads Junior High. Central Control suspected that she was from the Negaverse. Luna seemingly confirmed the suspicion when she and Serena noticed Amy's lost her disk was possessed by dark energy.

When Serena used Luna in an attempt to undermine Amy, she discovered that Garoben, a Negamonster impersonating Amy's teacher, was the true agent of Beryl. Garoben's attempt to drain Amy's energy forced the symbol of Mercury to reveal itself on her forehead, so Luna gave her the pen that she used to transform with the phrase "Mercury Power". After she used Mercury Bubbles Blast to make Garoben cold and obscure her vision, Sailor Moon destroyed Garoben.

Following the fight with Garoben, Amy obtained the Mini-Data Computer and VR Visor and used both against the time-manipulating Negamonster, Ramwoir.

When Raye Hino (Sailor Mars) was discovered, Amy learned to get along with the Sailor scout of Mars far better than Serena, who constantly butted heads with Raye. Amy and Raye typically acted as the voice of reason, planning strategies and working together to aid their clumsy leader in the fight against the Negaverse. Together, Amy, Raye and Serena foiled all of Jedite's schemes and defeated him. They also worked together to foil the rest of Neflite's evil plans.

During Zoycite's bid to capture the Rainbow Crystals, Amy met Greg, a young student with the power to see into the future. She attempted to protect him in order to prevent his crystal from being stolen by Zoycite, but was unsuccessful. However, during the Sailor Scouts' battle with Greg's Shadow Warrior persona, Bumboo, Mercury tried to get through to Greg by appealing his humanity. His resistance against the Negaverse allowed Serena to heal him using the Crescent Moon Wand. Lita Kino and Mina Aino joined their cause.

The Past Revealed
During their final fight with Zoycite, Amy and other Sailor Scouts learned of their pasts as subjects of the Moon Kingdom and protectors of Princess Serena. Though their memories were restored, they lost Darien Shields, Tuxedo Mask and the Prince of Earth, in the process. Though Amy and the others promised to help Serena save Darien from the Negaverse, there were times when none of the Sailor Scouts believed it was possible to save him from the Negaverse at all. and all five Sailor Scouts foiled all the villains' schemes.

Amy was reunite with Greg at a later time when the brainwashed Prince Darien would attempt to recapture the former holders of the Rainbow Crystals and restore their Shadow Warrior Personas. Amy and the other Sailor Scouts, however, are able to save all of the former Shadow Warriors from the Negaverse's plans.

In their final attempt to stop Queen Beryl and save Prince Darien, the Sailor Scouts were blockaded by the Doom and Gloom Girls. Mercury was taken captive after she was captured by one the Doom and Gloom Girls vines, used to drain her energy. Mercury was late reunited the other Sailor Scouts to help Princess Serena defeat Queen Beryl. After Beryl's defeat, Amy and the others were freed from the Negaverse, however, none of them remembered being Sailor Scouts.

Doom Tree Arc
When Alan and Anne sent the Cardian Minotaur to gather energy for the Doom Tree, Luna restored Sailor Mercury's memory, along with Sailor Mars, Sailor Jupiter, and Sailor Venus. She learned an attack called "Mercury Ice Bubbles Freeze", during Cardian Skulker's attempt to steal energy from babies.

Negamoon Arc
Amy almost moved to Germany, but at the last second stayed with her friends to help them defeat the droid, Frosty, using her new move Shine Aqua Illusion she also received her new wrist communicator and transformation pen and transformed with "Mercury Star Power".

Amy won a chess tournament, defeating Bertie, one of the four Negamoon Sisters under Rubeus' command, in the finals. Bertie's response was to do a "freeze play" game with her, where whenever a player lost chess pieces, parts of their body they would be frozen, but Tuxedo Mask shattered the spell, and Bertie turned good when Serena used the attack Moon Crystal Healing Activation to heal her.

During the Negamoon Family's search for negative points to capture, students at Amy's school (among them, Melvin) were turned against her, Serena and Molly Baker. Influenced by negative energy, Melvin and the others accused Amy of cheating and mocked her, calling her "Amy the Super Nerd". Though Amy was hurt by the accusations and teasing, she tried her best not to show it around her friends, who assumed the "shock" of being called a cheater was the primary reason she refused to be openly upset about the situation. Amy aided Sailor Moon in defeating the Negamonster, Mistrust, responsible for the student's behavior.

Amy also fought alongside the others against the Heart Snatchers. Amy was the third of the Sailor Scouts to be targeted for her Pure Heart. The Daimon, Dovlin, extracted it, but it was later returned to her.
