Standard Equipment:

  • Tiara
  • Deep Aqua Mirror
  • Marine Cathédrale
  • Neptune Crystal
  • Galactica Bracelets
  • Tiara: Part of any Sailor Senshi's fuku, except Sailor Cosmos, Sailor Galaxia, and Eternal Sailor Moon. When looking at the tiara from a distance it appears to have a rather simple smooth golden design with a circular red gem at it's centre. On closer inspection though one can see that it in fact has subtle details engraved in its surface and the gem itself is encased in a golden frame.
  • Deep Aqua Mirror: Sailor Neptune's Talisman, which she used to perform the attack "Submarine Reflection". It was used not only as a weapon, but also to reveal the truth and the location of enemies.
    The item is already possessed by the owner; rather than being made to summon the Holy Grail they were made to summon Sailor Saturn herself. The mirror has been seen to work for others beside Sailor Neptune as Chibiusa once used it to locate and teleport to a different location. Michiru gave Chibiusa the mirror at some point before the Dream Arc. When the Outer Sailor Guardians returned, Chibiusa teleported the mirror back to Super Sailor Neptune in order to help her fight the Dead Moon Circus.
  • Marine Cathédrale: The name of Michiru's violin. During one of her concerts, an audience member states, "I hear that her violin is a five hundred million yen Stradivarius named after the temple of the sea."
    Michiru, as Sailor Neptune, is also able to use her violin for attacking, as she used it to perform an unnamed sound attack in Act 30. She is also able to perform two attacks with her violin in the manga: Submarine Violin Tide and Galactica Violin Tide.
  • Neptune Crystal: The Sailor Crystal that Michiru Kaiou used to transform into the Super Sailor Neptune in the manga. It was given to her by Hotaru Tomoe.
  • Galactica Bracelets: Bracelets worn when Sailor Saturn was reconstructed to be a loyal subject to Sailor Galaxia. Can be used to fire blasts of energy at an enemy. Destroying them entirely and allowing the user to take their Sailor Crystal from them. They have purple and green gems on them.

Intelligence: Very intelligent. She attended a school reserved for geniuses simply to spy on her enemies in the Infinity arc of the series and excelled in academics and the arts without much effort. She's also been shown to have sharp intuition and some form of precognition, which is enhanced by her Deep Aqua Mirror.

Weaknesses: In-Character she is less likely to use her Talisman due to it having a very large obvious energy signature and if the three Talismans are gathered they will summon Sailor Saturn, whose destiny is to destroy the world. Needs to maintain concentration to use her magic. | None notable normally, under the control of Sailor Galaxia, she loses her life if her Bracelets are destroyed | Unknown

Notable Attacks/Techniques:

Magic: Michiru is a talented sorceress, who can create images and illusions at will and can channel her magic through her violin music, able to paralyze opponents.

Henshin: Michiru can use the Power of her Sailor Crystal to Transform into Sailor Neptune and then her stronger forms. The Henshin Power can also be used to teleport through dimensions or reverse enemy-magic.
  • Neptune Planet Power, Make Up: The first command used by Michiru Kaiou to transform into her standard, regular Sailor form as Sailor Neptune in the manga, and the only one shown to be used in the first anime series. Michiru shouts this phrase while raising her hand in the air and she became Sailor Neptune in an instant.
  • Neptune Crystal Power, Make Up: A transformation phrase used by Michiru Kaiou in the manga. She used it in order to transform into Super Sailor Neptune, using her Neptune Crystal. while holding her hand in the air she becomes Sailor Neptune in an instant.

  • Deep Submerge 「深水没ディープ・サブマージ」: Neptune summons the energy of the watery abyss. This attack is similar to the Moon Spiral Heart Attack.
  • Submarine Reflection 「深海鏡射サブマリン・リフレクション」: Utilizing the Deep Aqua Mirror, Sailor Neptune can create a beam of blue light. This light reveals her target's weakness, or destroy enemy spells and illusions, as well as destroy opponents who contain magic within them (like those resurrected by a curse).

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.

The Highest Conventional State of Sailor Senshi, in this state Sailor Neptune'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.

  • Star Seed Rip/Removal: The Galactica Bracelets also allow for the ability to steal the star seeds, taking away the very essence of a being and leaving the body to evaporate into dust.
  • Submarine Violin Tide 「深海提琴潮流サブマリン・ヴィオロン・タイド」: She uses her violin to create a tide of energy that washes her opponent away. This attack was likely comparable to Eternal Sailor Uranus' Space Turbulence.
  • Galactica Violin Tide 「ギャラクティカ・提琴潮流ヴィオロン・タイド」: An attack used by Sailor Neptune in the manga. It is an alternate "evil" version of her attack Submarine Violin Tide.
  • 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.

At the end of the series, Michiru absorbed the Lambda Power and could exist in "Perfectly Heavenly Form" within the Galaxy Cauldron which normally erases existence.

Key: Base Sailor Neptune | Super Sailor Neptune | Eternal Sailor Neptune | Evil Sailor Neptune | Lambda Michiru

  1. It's never been confirmed if the Sailor Senshi maintained their Lambda Powers outside the Galaxy Cauldron. As such it's unlikely these powers can be ascribed to EoS Sailor Neptune, and it should be probably be considered along the lines of one-off power-ups.
