Sailor Cosmos
セーラー・コスモス
Sailor Cosmos was a character who played an important part in the Stars arc of the Sailor Moon manga, where she was revealed to be the true form of Chibi Chibi (who had very different origins in the anime). After Sailor Galaxia's death, Chibi Chibi revealed to Sailor Moon that her true form was in fact Sailor Cosmos. Her future, as told to the Sailor Quartet, was not a hopeful one - Sailor Chaos waged war against the universe, and everything and everyone Sailor Cosmos knew was destroyed to the point where nothing could be salvaged even if the war ended. Upset, scared, and unable to do anything, Sailor Cosmos ran away from her future, opting to go into the past to destroy Chaos before it achieved its terrible Senshi form. To destroy Chaos, she decided that she also had to destroy the Galaxy Cauldron, and so in the form of Chibi Chibi she tried to guide her past self, Eternal Sailor Moon, towards that end. Even though Eternal Sailor Moon was determined to save the Cauldron and chose a different path, she nevertheless inspired hope in Sailor Cosmos with her power and courage. She stated that the Eternal Sailor Moon who had saved the galaxy was, in fact, the true form of Sailor Cosmo
