Galaxia started out a a good pwerful Senshi. Some will argue that she is the most powerful Scout of all. I disagree with this of course. In the manga it seems that she doesn't age. She was around much before the Sailor Wars. After traveling from plnet to planet she bagain to feel that the people were 'trash'. I think that she started to see the true evil many had inside of them, and started losing hope. Others will say she just let the evil side of herself slowly take over her. There was a scene in a bar where she is saying, "These people are trash. All these planets are trash; I deserve better." When stumbling out of the bar she ran in the spirt of Sailor Chaos. Chaos's goal was to take over the universe. To do that she needed four starseeds. One of which was it's own starseed of entropy, Sailor Galaxia's starseed "The Light of Hope", Sailor Moon's starseed of love, and Sailor Kinmoku's of stars and souls. Chaos told Galaxia that they could give Galaxia the power to make a new untrashy universe. Galaxia accepted, and Chaos gives her two bracelets and in a sense takes over her body. They go to take the two other starseeds needed, and other peoples starseeds and stores them in the Great Sapphire Crystal at Shadow Galactica. She has two attacks in the Manga. Galactica Super String and the Galactica Inflation. When Sailor Moon rescuses Galaxia, she realizes what she has done and destroys her Chaos braclets. This kills her.
