Notable Attacks/Techniques:


  • Mercury Power, Make Up: The first command used by Ami Mizuno to transform into Sailor Mercury in the manga, first anime series and the second anime series, and the only one in the live-action series. In the manga, however, the transformation is instant, and all Ami have to do is cross her hands over her chest while holding her pen and say her phrase in order to transform. She can all choose to raise her pen in the air and again transform momentarily.
  • Mercury Star Power, Make Up: The second phrase used by Ami Mizuno which allows her to transform into Sailor Mercury. In this transformation, Ami holds up her hand as a stream of blue sparkles swirled around it, alighting on her fingertips and turning them light blue. Her Star Power Stick appears, spinning, and as she takes a hold of it the Mercury symbol in the center of the star begins to spin. She then swept the stick over her head and around her body while a stream of blue water emitted from it, forming her leotard, gloves and boots. A sparkling ripple expanded over her body, and a rush of bubbles formed the rest of her sailor fuku, and Sailor Mercury assumes her finishing pose.
  • Mercury Planet Power, Make Up: The third transformation phrase used by Ami Mizuno to transform into an even stronger, upgraded version of her regular Sailor form as Sailor Mercury in the manga. It was given to her by Neo-Queen Serenity. Ami does not appear to use a pen for this transformation; instead, she simply lifts up her hand and says the phrase, then transforms instantly. A magical device is not used to transform.
  • Mercury Crystal Power, Make Up: The fourth command used by Ami Mizuno to transform into a "super" version of Sailor Mercury in the manga, and the third command used in the first anime series. In the manga, Ami uses her Sailor Crystal, a heart-shaped crystal called the Mercury Crystal, to do this transformation (which explains the name). As with all manga transformations, this one is instant as well, but comes with an upgraded outfit similar to the anime Super outfit, with a longer back bow, more earrings, a star on the choker, and a heart on her bow. When she upgrades again in Act 49, the heart on her bow becomes a star, and, based on the artbook illustration, most of her other accents change to stars as well in this form. She just raises her hand and became Sailor Mercury right away.


  • Henshin: Ami can use the Power of her Sailor Crystal to Transform into Sailor Mercury and then her stronger forms. The Henshin Power can also be used to teleport through dimensions or reverse enemy-magic.
  • Sabão Spray: Sailor Mercury's first technique produced a thick fog that obscured the area, but in which the Senshi could see clearly. It was a support ability, incapable of directly harming enemies.
  • Sabão Spray Freezing: A more powerful form of Sabão Spray that could actually harm, or at least immobilize, enemies.
  • Double Sabão Spray Freezing: An enhanced form of Sabão Spray Freezing, used on one occasion against Giwaku.
  • Mercury Aqua Mist: Sailor Mercury creates a dense fog to disorient enemies. It originally did not have a name, but in reprints was called its current name. It can also be used as an automatic measure when attacked.
  • Crash Launcher: Used in the Sailor Moon arcade game.
  • Hyperspace Area Formation: Creates a Hyperspatial Pocket Dimension meant to trap enemies. Full power of the extent is unknown.
  • Shine Aqua Cutter: Used in the Sailor Moon arcade game.
  • Shine Aqua Illusion: Creates a Water Storm powerful enough to wipe out advanced robots from the future. The attack carried more power then Post-Serenity Sailor Moon by scaling.
  • Shine Snow Illusion: A snow variant of the above Shine Aqua Illusion, possibly can freeze opponents.
  • Mirage Wave: Used in the Sailor Moon arcade game.
  • Mercury Aqua Mirage: Shoots out numerous waves of water from her palm with enough force to threaten the Witches V. The attack can hit on the spiritual plane and was able to destroy a spirit in the short story Ami's First Love.
  • Super Sailor Mercury: A more powerful form of Sailor Senshi that comes from the holy powers of the Holy Grail, the Super Sailor Power-Up increases the Sailor Senshi's Power by 10,000 times.
  • Mercury Aqua Rhapsody: She uses the Mercury Harp, a conscious harp, that shoots an intense stream of water and large bursts of planet power capable of destroying an Amazoness Quartet.
  • Aqua Ribbon Upper: Used in Sailor Moon for the Mega Drive.
  • Sailor Planet Attack: A group attack performed by the Inner Sailor Senshi, one of the most powerful attacks used in the manga that incorporates a number of Sailor Senshi every time it is used. Interestingly enough, Sailor Moon is not required for the attack to work. The attack was first used by the Inner Senshi to kill Kunzite.
  • Break Step: Used in Sailor Moon for the Mega Drive.
  • Sailor Planet Power: A group attack similar to Sailor Planet Attack, but much stronger and more powerful.
  • Water Stream: Used in Sailor Moon for the Super Famicom.
  • Galactica Gale: The attack was performed by Sailors Mercury, Venus, Mars, and Jupiter while they were all under the control of Sailor Galaxia's bracelets.
  • Reverse Spin Kick: Used in Sailor Moon S for 3DO.
  • Galactica Planet Attack: The Inner Senshi (excluding Sailor Moon and Sailor Chibi Moon) and the Outer Senshi performed this attack while they were under the influence of Sailor Galaxia's bracelets. It is an alternate version of Sailor Planet Attack.
  • Reverse Break Step: Used in Sailor Moon R for the Super Famicom, Sailor Moon S: Jougai Rantou!? Shuyaku Soudatsusen, and Sailor Moon SuperS: Zenin Sanka!! Shuyaku Soudatsusen.
  • Water Bullet: Used in Sailor Moon S: Jougai Rantou!? Shuyaku Soudatsusen and Sailor Moon SuperS: Zenin Sanka!! Shuyaku Soudatsusen.
  • Eternal Sailor Mercury: The Highest Conventional State of Sailor Senshi, in this state Sailor Mercury's powers are comparable with the strongest Sailor Crystals in the Universe. This state increases her stats and her attack power by a drastic degree.
  • Lambda Ami: At the end of the series, Ami absorbed the Lambda Power and could exist in "Perfectly Heavenly Form" within the Galaxy Cauldron which normally erases existence. Having Absorbed the Lambda Power, Ami can use the powers of any Sailor Senshi, except for Sailor Chaos.
