Unlike the rest of the Solar System Sailor Guardians (besides Sailor Pluto), her uniform is sleeveless, giving off the illusion of a swimsuit which is supposed to be reminiscent of Mercury's power over water.

Her belt is now made up of two ribbons, the top one being dark blue and the bottom one being light blue, her brooch at the center of her chest bow is dark blue and star-shaped, and her back bow is a lighter blue and is back to its original size with narrow, long, dark blue ribbons extending from it down to her knees.

As Princess Mercury, she wears a dark blue strap dress with light blue cloth that goes past her feet and a dark blue choker that is tied into a ribbon at the back with the streams running down her back. She has a gold necklace and her straps have three gold ornaments each. Her necklace and ornaments each have dark blue gems in them and she wears small dark blue stud earrings and dark blue high-heeled shoes.
Information[]
Ami is an only child who lives with her mother Saeko, a respected doctor, and her father, a painter. However, her parents undergo a divorce, leaving Ami in her mother's custody while her father becomes a freelance artist.
Ami longs to become a doctor like her mother and grows to be a very intelligent girl to the point of becoming a national genius. Unfortunately, her peers become envious of her and mistake her shy demeanor for snobbishness, assuming Ami thinks she is too good to associate with them. This alienation causes her to live a very lonely life.
Dark Kingdom arc[]
Ami makes her debut appearance in Crystal, although it is in a non-speaking cameo, at the very end of episode one, where she retreats for cover at Juban Public middle school as a rainstorm begins to occur.
She reappears in the 2nd episode, in which she becomes Sailor Mercury for the first time in Crystal. In this episode, she is seen as a shy girl with hardly any friends. When Usagi meets her, they hit it off well. She is soon brainwashed by the Dark Kingdom at the Crystal Seminar, but is snapped out of it when Usagi as Sailor Moon is in danger. Seeing Sailor Moon in danger allows her to awaken her powers, and she transforms into Sailor Mercury. After she has transformed in Act 3, she used her unusually strong Mercury Aqua Mist attack to defeat Jadeite by covering his vision with fog and steam. This allows Sailor Mars to defeat him by combining her innate spiritual powers with her fire/flame-related attack to purify evil forces.
Later on, she is given special goggles that enable her to scan for enemy activity and figure out complex situations very easily. She can use her head microphone to communicate with her fellow Sailor Guardians.
Black Moon arc[]
Granted even greater strength and powers from her mystical Star Power Stick, Sailor Mercury is a lot stronger than before. Her attacks related to the element of Water are even stronger and more effective. Unfortunately, she is no match for Beither's own hydro-kinetic abilities and is trapped by her water orb, and therefore, taken captive.
Upon awakening in the Chamber of Darkness, she succeeds in regaining her full strength and abilities with the aid of Sailor Moon's power and teleports beside her in a streak of light blue light. She uses her Shine Snow Illusion attack against Prince Demande and Rubeus, but is unable to break through the sinister shield created by Wiseman himself. Fortunately, she escapes with Sailor Moon, Mars and Jupiter back to where Sailor Pluto and Sailor Venus are waiting.
She is unable to do anything as Prince Demande takes the Silver Crystals of both the past and future; about to merge them together. She regains consciousness and sees that everything has stopped in its tracks and realizes that Sailor Pluto has used her power to stop all of time, thus breaking the third taboo. She is astounded when Chibiusa broke free of Black Lady's influence and awakenes as Sailor Chibi Moon. Mercury watches sadly as Sailor Chibi Moon runs to Sailor Pluto's side, saddened at the sacrifice her dearest friend made for them. She then joins Sailor Moon, Sailor Chibi Moon, Tuxedo Mask and the other three Sailor Guardians to destroy Death Phantom, who has finally revealed his true self. With the awakening of Neo-Queen Serenity, Mercury is given new powers as the Guardian of Wisdom with planet power.
Infinity arc[]
From the new planet powers granted by Neo-Queen Serenity, Mercury is stronger than ever. Her most recent water-related attack is Mercury Aqua Mirage, which covers her enemy in a swarm of very cold water. When a brand-new monster takes control of a young girl from Mugen Academy, Mercury uses her goggles to scan for any weaknesses. With her new abilities, she attacks the Daimon but it is too strong for her new attack. She notices two shadowy figures nearby but is unable to see far enough to identify them.

Sailor Guardian Info[]
As the Sailor Guardian of Water and Intelligence, Sailor Mercury has attacks related entirely to liquid water as well as ice, snow, frost, sleet, mist, steam, fog and cold. Her steam/mist/fog-related attacks enable Mercury to blind her opponents creating cover for her comrades to use the element of surprise. She is capable of freezing monsters in solid ice and frost and dousing them in water. She can also create strong waves and whirlpools, and even freeze her enemies in cylinders of solid ice and snow.
Like the other Sailor Guardians, she can create an exceptionally strong, bright blue force field for protection; capable of withstanding extensive damage of energy-based attacks and also flying and levitating. Another useful ability she possesses is teleporting herself and others to another extra-dimension entirely; one that is separated from Earth (an ability that she did not possess in the original anime). To utilize this strong teleporting ability, she calls out Hyperspatial Sphere Generate.
She is the smartest and most intelligent of the Sailor Team and has a miniature supercomputer that lets her figure out complex situations easily, and goggles that enable her to scan enemy territory for hidden traps, and revealing the vulnerabilities of enemies.
