Chibi Chibi is a mysterious little girl who appears in the last arc of the manga, is the civilian identity of Sailor Chibi Chibi, and is the disguised form of Sailor Cosmos. This is the original depiction of the manga character created by Naoko Takeuchi.
Chibi-Chibi is a small girl with the appearance of a toddler. She has dark pink hair that is tied into two heart-shaped odango and blue eyes. She wears a white, long-sleeved shirt with a dark pink bow and a light pink heart brooch at its center, a blue skirt with a blue back bow, white socks, white shoes with pink hearts and accents, and pink heart earrings.
Chibi-Chibi is actually Sailor Cosmos from the far future. She used the disguise of a little girl, most likely, because she intended to keep her identity secret in order to carry out a mission to influence her past self, Usagi Tsukino. In order go get close to her past self, she chose the disguise of innocence. A child that, hair color-wise minus shade, resembles Usagi's future daughter, and knew Sailor Cosmos, having lived that time once before, knew Chibiusa had gone home and Mamoru went to study abroad leaving Usagi alone and vulnerable and more accepting of a stranger child from the future.
When Chibi Chibi first appears Usagi and the girls try to figure out who she is and where she came from, but they fall flat. Chibi Chibi, can become a senshi, Sailor Chibi Chibi. Later in the Stars arc, Chibi Chibi finally reveals her true form by transforming into Sailor Cosmos, the ultimate form of Sailor Moon.
- Chibi Chibi is often mistaken to be Chibiusa's daughter, but Chibiusa clearly stated that Chibi Chibi cannot be her daughter.
- This is proven true, because in the manga, Chibi Chibi is actually Sailor Cosmos. And Sailor Cosmos is the future form of Sailor Moon.
- Also, Chibi Chibi is often mistaken for being Usagi and Mamoru's second daughter, though this is wrong as well.
- In the anime, she is really Sailor Galaxia's star seed.
- Chibi Chibi in the anime and manga were not real identities. In the manga it was a disguise for a real person, in the anime it was a non-living entity looking for a new soul and body for it. In the anime, it also transformed into a sword among other things.
- In the manga, Chibi Chibi is also unlike her anime counterpart by being more mature and less childlike. She also can form more speech than just parroting Chibi Chibi.
