STRENGTHS: When she was good, Sailor Galaxia was a kind and caring person, willing to seal away Chaos within herself to save the entire galaxy.
WEAKNESSES: Galaxia was an arrogant Sailor Guardian who was unsatisfied with the power she held. She seemed to have a very large ego as well, since she was
convinced that she deserved to have the most powerful star in the entire universe. Other than that she was usually calm and collected, as seen with how she
mostly acted when around her minions and Sailor Moon. But, that does not mean she was without a temper.
As a Sailor Senshi, her uniform is not the same as the other Sailor Guardians. Her Sailor Fuku is pure gold with a gold head dress, similar to a Russian kokoshnik. Her hair has been rolled back to fit into the headdress, overall resembling a crown. She wears orange lipstick and light purple eyeshadow.
In her Chaos form, her fuku turns black and so does her head dress and boots. Her skin turns light purple, her lipstick turns dark purple and her hair turns red. Galaxia I
Her daughter Catora was fighting by her side at the time and witnessed her mother’s last atempt at saving the world from destruction. But before she could flee to warn the girls that would be the future Sailor Senshi, Chaos used its power to take over her mind and control her. By then, she was the one that wanted to destroy the world by attacking the Tsukino sisters and their friends. When Catora was free from the control of Chaos, she asked both Bunny and Jasmine to save her mother from the evil that controls her or it might be too late. And after that, she was gone.
Now completely controlled by Chaos, Sailor Galaxia sought to steal all the star seeds in the universe to control it for herself in the name of “Star Galaxia” and to seek revenge on the two girls that she thinks killed her daughter Catora. Among the planets she wrecked was
the planet Kinmoku. The Princesses of the planet managed to escape destruction and flee to Earth, the last place that Sailor Galaxia had not invaded. Then she sent her Sailor Animates to find true star seeds that shine forever—in other words, Crystals that hold power longer
than any other. After numerous failures, Galaxia would kill all of her Animamates, and eventually confronted the Sailor Senshi herself.
Galaxia first battled Princesses Kakyuu and Kaiyuu, who had recently come out of hiding. While Kakyuu and Kaiyuu was able to hold a barrier against Galaxia for a time, she was eventually overpowered and killed. The Inner Sailor Senshi, and the Outer Sailor Senshi then initiated their own plans of attack. But while trying to protect that girls that had recently found out that they were Sailor Senshi, the Inner Senshi’s star seeds were taken by Galaxia. When there was no other way of trying to stop Galaxia, Sailor Moon and Sailor Star Moon instead gave Sailor Galaxia the strength to expel Chaos from her body, an act that returned darkness to the hearts of all life, where it belonged. Once this was done, Sailor Galaxia's soul was restored and the star seeds she had stolen were released. Galaxia then left with the task of returning the star seeds home.
