Chibi Usa Profile
Chibiusa, is one of the central characters in the Sailor Moon metaseries. When she first appears, she is a small child from the 30th century who visits the past to seek help from the series' primary heroines, the Sailor Senshi. She later returns, a few years older, in order to train as a Senshi herself—Sailor Chibi Moon.
Chibiusa is formally named Usagi Small Lady Serenity but in the 20th century she goes by the name Usagi Tsukino. She is given her nickname by Mamoru Chiba in the manga and Usagi in the anime in order to differentiate from the older Usagi Tsukino, Sailor Moon. The nickname is a combination of chibi (meaning runt, dwarf, shrimp) and her given name, Usagi. In her own time period, she is always called Small Lady. In the English-language adaptations, where Usagi had been changed to Serena, the diminutive "Rini" was used for Chibiusa's name.
Creator Naoko Takeuchi describes Chibiusa as a precocious brat who likes pulling pranks. She is the daughter of Usagi Tsukino and Mamoru Chiba. Her real name is the same as her mother's, but is called Chibiusa in Japanese (and Rini in English) to avoid confusion between the two. Her name in the English-language version of Sailor Moon, Rini, is a diminutive of "Serena", the name of her mother. She is known for having pink hair put into a unique style that resembles rabbit ears on top of her head. Chibiusa's hair is apparently truly pink, and not just colored that way for stylistic purposes; its color is stated in the manga's first Picture Diary and in the poem about her in the Sailor Stars CD single.
In Act 20 of the manga, it's mentioned that she is 900 years old, her youthful appearance attributed to the fact that she suddenly stopped growing when she was five. The reason for this is never fully understood, but she begins to age after she becomes Sailor Chibi Moon. By the time of the Dream story arc, she claims to be 902. Her exact age was not disclosed in the anime, and her time traveling complicates guessing. The candles on a birthday cake in one memory indicate that she is about five years old when first introduced, and she seems to be 8 or 9 years old when she returns later on. Exposure to the Silver Crystal renders all of Crystal Tokyo's inhabitants functionally immortal.
Often shortened by her parents and family friends to Small Lady, this is the name that Chibiusa is known by in the future. It is unchanged in the part of the English anime dubbed by DiC, but changed to Little Lady in the episodes dubbed by Cloverway.
In the manga, this form appears more frequently and receives more explanation. It is the name given to her by her parents so she often uses this to identify herself in the future. The only other character to use it, besides the royal family and its friends and allies, is Diana, who periodically calls her by Small Lady and uses honorific endings to indicate that Chibiusa is a princess. Her princess form also appears in Artbooks IV and the Materials Collection, in which she is drawn among the other Senshi in their specific gowns. She wears a light pink gown unique from all the others.
In the anime, Chibiusa changes into her princess form when she needs more power than her Senshi or civilian forms allow, similar to how her parents can become Prince Endymion and Princess Serenity when they need more power. In this form, she wears a dress and jewelry identical to that of Princess Serenity, albeit smaller. This happens twice, during the final battles of the second and fourth series. Like her mother, she grows a pair of functioning, angelic wings during the Supers climax. She does this after Usagi, as Serenity, grabs her while they are falling, and the two of them collide with Pegasus. It is unknown if she grew the wings on her own or with Usagi's or Pegasus' help. The Chibiusa of the future, Small Lady, is also shown in her princess dress when she is not transformed, so this form is not exclusive to power-ups.
