Chibi-Chibi is mysterious, also cute little girl with her red hair in heart-shaped "dumplings" on her head. She first appears in Sailor Stars (fifth season; Episode #182). She resembles Usagi and Chibi-usa, but little is revealed about her origins until the end of the series.

    Chibi-Chibi is a very generous little girl who carries a small parasol and loves to eat food as much as Serena does. She has substantial powers, such as hypnotizing Usagi's mother into believing that she and Serena are sisters, and vicious dogs. Chibi-Chibi does not say much except for "Chibi", though she can mimic the last few words of a sentence when she is asked a question. She is about to 2-3 years old. Eventually is revealed that she can transform into Sailor Chibi-Chibi.
