Sailor Galaxia was an extremely powerful Sailor Senshi who appeared as an antagonist in the anime, manga, and musicals, and who will appear in Sailor Moon Crystal. She was known as the "Soldier of Solitude" (孤独の戦士) and the "Soldier of Destruction" (破壊の戦士).


In the anime, Sailor Galaxia was the most powerful Sailor Senshi in the galaxy, and as such fought in the Sailor Wars against Chaos. In the great final battle, she trapped Chaos and sealed it within herself in order to save the galaxy. However, Chaos was too strong for her and she realized that it would gradually overwhelm her. In order to protect herself against that threat, she removed her Star Seed and sent it out into the universe, telling it to find someone who would welcome it warmly.

As she fell under Chaos' influence, Sailor Galaxia began to attack planets in the galaxy, destroying them and taking the true Star Seeds belonging to other Sailor Senshi. She gathered followers, the Sailor Animamates, in order to help her with this mission.

In the meantime, her Star Seed travelled long and far before it finally reached the Earth and found Usagi Tsukino. It then took the form of Chibi Chibi and masqueraded as Usagi's sister. However, Galaxia's Star Seed was the Light of Hope that Princess Kakyuu and the Sailor Starlights were searching for in order to defeat the legendary Senshi. With the help of the Light of Hope, Princess Serenity fought against Sailor Galaxia, and finally managed to free her from Chaos' influence. Galaxia then departed, leading all of the Star Seeds she had collected back to where they belonged.


  • Bracelets - Sailor Galaxia could fire blasts from her bracelets that would remove a person's Star Seed.
  • Sword - Sailor Galaxia possessed a sword which strongly resembled the Fuuin no Ken.


In the manga, Sailor Galaxia was born on a planet she referred to as "trash" and wandered alone and miserable for an unknown amount of time before discovering that she had the power of a Sailor Senshi. That power alone was not good enough for her, though: she had to have the strongest power in the galaxy, and so she left her home planet.

While wandering the universe in search of this ultimate power, she heard about a place where all the stars were born. One day, she overheard a mysterious cloaked figure talking about that place, and he told her that the birthplace of the stars, the center of the galaxy, was the Sagittarius Zero Star.

Her main objective was to find more power, and to do so, she collected all the Sailor Crystals she could find. She made her base at the Galaxy Cauldron, the birthplace of the stars, and built an empire that she called "Shadow Galactica," with her power centered at her castle, Galactica Palace. As she sought out Sailor Crystals to add to her collection, she also gained followers to whom she promised power in return for their service. Some of those followers killed the Senshi of their home planets and stole their Sailor Crystals, using that power to became the Sailor Animamates.

Galaxia knew, however, that Chaos was only helping her in order to have her do his dirty work. She was not powerful enough to defeat Chaos alone, and as a result she planned to use Sailor Moon to defeat Chaos for her. Galaxia came to the Sol System and captured the Sailor Crystals belonging to the Solar System Senshi, effectively killing them. She then recreated their bodies, as well as that of Prince Endymion, as her servants and commanded them to fight Sailor Moon in order to cause her pain. If Sailor Moon gave in to anger and despair, then Chaos could take control of her; if that were to happen, their two opposing powers would cause both beings to self-destruct, leaving Sailor Galaxia to retrieve their Star Seeds and become the strongest Senshi in the universe.

To this end, she threw the Solar System Senshi's Sailor Crystals into the Galaxy Cauldron, melting them into nothingness, and made Endymion kiss her boots before she threw him in as well. Endymion's death also caused the disappearance of Sailor Chibi Moon, who had arrived from the future to aid her mother. Sailor Moon's grief infused Chaos with power, but Chaos used that power not to strike down Sailor Moon, but against Galaxia herself, hurling her over the precipice toward the Cauldron. Sailor Moon saved Galaxia's life and protected her from Chaos' darkness with her own shining light, and when faced with Sailor Moon's purity, hope, and love, Galaxia lost her will to fight. Her bracelets shattered, and she disappeared.



Tamami Matsumoto
as Sailor Galaxia

In her various appearances in the musicals, Sailor Galaxia was played by Saori Sara, Tamami Matsumoto, Takemi, Yumie Sakaguchi, and Coco Isuzu. She had one image song, "Galaxia Gorgeous."

Sailor Galaxia appeared in seven musicals in the first run, tying with Queen Beryl for the most appearances of any single villain. In her first three appearances she enlisted the help of the Sailor Animamates, while in later musicals she was joined by the Amazon Trio, the Shitennou, and Queen Beryl. In several musicals she transformed into Sailor Chaos, which in that continuity strongly resembled her appearance in the final episode of the anime. She was intensely afraid of Chibi Chibi in the musicals, which led to her subordinates (particularly Queen Beryl and Tiger's Eye) mocking her behind her back for it. In her final musical, she was revived by the Sailor Senshi along with Queen Beryl and the Sailor Animamates.

  • Sailor Galaxia's name is commonly considered by fans to be a reference to a galaxy. It comes from the Greek/Latin word "galaxias," which was used to refer to the Milky Way specifically and later galaxies in general.
