Special Note for Future Chapters
Let me begin by saying much of my factual information on Sailor Cosmos, Chibi Chibi and the future comes from I will begin by presenting their evaluation of who Cosmos and Chibi Chibi are, then jump into my updated, fanfiction version.
According to the site, Sailor Cosmos is the future version of Sailor Moon who returned to the past in the form of Chibi Chibi. In her time period she was alone, struggling against Chaos. She returned to the past to guide Sailor Moon and encourage her to destroy the Cauldron in order to prevent any more wars. Sailor Moon, of course, refused, and descended into the Cauldron to save those she loved. Cosmos returns to the future to continue her war with Chaos.
Now, in my interpretation, Cosmos is from an alternate future. Here is an account of what happened, translated from her own words:
"From an overwhelming future, where I lost the war to Sailor Chaos, I gave up everything and ran away. Repeated massacres, a long, painful war... The enemy that appeared, the strong, enormous Sailor Chaos... With the way of fighting we had used, we didn't stand a chance. Even if we defeated it, even if we returned the peace of before, the damage taken, the price we paid, would be too much. Too far-reaching. We couldn't do it. I don't know anymore, why there are wars. What is right. What should I do? When I'm lost, when I'm hurt, I remember. The war here. Back then at the Cauldron. If I had eliminated it, would the pain, would the war have ended? After regretting it so many times, I came here. To make it right this time."
However, in both the manga and the anime, Sailor Moon managed to dispel Chaos. It was said (at least in the anime) that Chaos had been sent back to everyone's minds, where it belonged. Unless someone like Galaxia went and absorbed Chaos into her body again, there can be no Sailor Chaos. Perhaps in Sailor Cosmos's reality this failed somehow, but as the series is assumed complete and the future laid out quite nicely for our heroine, we can assume that no enemy as strong or stronger than Chaos-Galaxia appears.
That being said, Cosmos is powerful enough that she could probably travel between realities/dimensions. Of course, since Cosmos (by nature of her name/title) is stronger than Galaxia, and Galaxia originally defeated Chaos (even if only short-term), Cosmos would not have nearly as much trouble...but I digress. We'll deal with the reality Takeuchi-san did provide for us.
So, going with the assumption that Cosmos could be from another dimension, where is that same version of her in our dimension? What if it isn't Tsukino Usagi that reaches that final, ultimate stage of senshihood? Maybe it's the next Sailor Moon. In the future of Usagi's dimension that we've been made privy to, the next Sailor Moon is most likely Chibiusa. She has the same potential as her mother (assuming her body ever ages...). Maybe it is she who can become Cosmos in this dimension?
Keeping that logic in mind, and that any daughter of Usagi's would be the next Sailor Moon, please enjoy the rest of the story as I update it. And remember, always review! Thank you.
