Sailor Chibi Chibi Moon

"Chibi Chibi"

Chibi Chibi is a very odd character. I don't know much about her myself and have only begun to collect the Sailor Stars episodes. But In keeping with tradition I will gather as much information as I can, and post only what I can confirm is true.

How Chibi Chibi arrived: 

Chibi Chibi fell from the sky one day, Much like Chibi-Usa, but she didn't fall in the middle of a romantic moment. Chibi Chibi floated down form the sky with an umbrella and Usagi found her. Usagi begin kind and gentle, asked Chibi Chibi where her parents were but the only reply Usagi received was "Chibi Chibi". When Usagi took Chibi Chibi home, her mother informed her that Chibi Chibi was Usagi's sister.

More Anime Info: 

Throughout the universe, there were Sailor Senshi to compete in the Sailor Wars. The strongest of them all was Sailor Galaxia. Sailor Galaxia won many star
seeds. An evil force, Chaos, erupted from the center of the universe, out to saturate anything and everything with its evil aura.

Being the peachy-keen person she was, Galaxia decided to try and stop it. The only way she could do so was to seal it inside her own body; however, she knew
she would not be able to control it. 

Before it completely engulfed her, she sent her soul (light of hope) out to the farthest corner of the universe, praying that it would survive, and fall into the care of
someone who could defeat the evil being she was about to become. This light of hope, or star seed, is Chibi-Chibi, and Sailor Galaxia became the most powerful
foe the Sailor Senshi had ever faced. Chibi-Chibi came to Earth and found herself in the care of the Sailor Senshi. She was later revealed to be Sailor Chibi-Chibi,
one of the most powerful senshi. She powered up Eternal Sailor Moon's tier, she brought Sailor Moon back to life, and even gave her a sword to fight Galaxia.
But alas, she died. She was, however, freed in the end like everyone else, and vanishes into the sky from whence she came.

Manga Info:

In the Manga, Chibi-Chibi appears much like she does in the anime, only she's not quite as annoying. She turns into Sailor Chibi-Chibi as well, but she can talk
and transform by herself, just like a normal Sailor Senshi (only a bit shorter). She's rather mysterious, and it is not until the final battle that we learn her origin. In
the Manga, Chibi-Chibi is Sailor Moon's future FUTURE self, Sailor Cosmos. Y'see, when Eternal Sailor Moon threw herself into Calderon, the mystical river
of birth and rejuvenation, in the last battle and sealed Sailor Chaos, there was still a tiny speck of Chaos still left in Calderon. This speck festered and grew to a
great enemy in the future, and Sailor Cosmos fled back to the past to destroy Calderon, thereby eliminating any possible threat. But what Eternal Sailor Moon
helped Sailor Cosmos realize was that the stream of life represented the birth of new hopes along with the evils, too. And if you believed in that hope, you
could always conquer the bad. Sailor Cosmos knew that she could no longer fear that threat with all the love and hope Eternal Sailor Moon gave her, and
faced her destiny as the true Sailor Cosmos, with confidence and bravery.
