Sailor Cosmos Profile
Sailor Cosmos first appeared in volume 18, act 51. She is the true form of Chibi Chibi, and also the
future form of Sailor Moon. She came from a world full of chaos where she fought against the powerful Sailor Chaos. After losing the war, she ran away. She decided to travel back to the past in order to make things right, by trying to help Usagi make the right decision. The decision she had not done, and come to regret.
In the form of Chibi Chibi in volume 18, she told Sailor Moon to destroy the Cauldron, which Chaos had merged with. This was to end the eternal battle, but in doing that, the future of the galaxy would disappear as well. No more stars would be born again. But Sailor Moon did not want the future to end in such a sad way, and told her to not abandon her hope. Sailor Cosmos decided to put her faith in Sailor Moon and revealed her true identity.
After Sailor Moon descended into the Cauldron, she decided to stop running away and go ahead to the future. She said that the current Eternal Sailor Moon is the true Sailor Cosmos. And that when she has the courage to stand alone, and the courage to accept everything, then at that time she too can be the true Sailor Cosmos.
