Chibiusa Tsukino

Princess Usagi Small Lady Serenity (nicknamed Chibiusa) is the Crown Princess of 30th Century Crystal Tokyo and the daughter of Neo-Queen Serenity and King Endymion.She is the civilian identity of Sailor Chibi Moon.

Personality
From her first appearance, Chibiusa is presented as a precocious and slightly spoiled little girl. She often picks fights with Usagi, intentionally trying to rile her up over the smallest of things. She has a close relationship with King Endymion/Mamoru Chiba, her future father, and often turns to him when she's feeling frightened or vulnerable. Chibiusa also holds her mother, Neo-Queen Serenity, in high regard, wishing she could be a graceful lady just like her. However, despite Usagi being a younger version of her mother, Chibiusa does not view her with the same respect and admiration, instead viewing Usagi as a clumsy crybaby. Among her peers, she's upbeat and outgoing, and despite being shy at first, quickly becomes popular with her classmates once she enrolls in school.

Appearance
Chibiusa has pink hair and red eyes. Like Usagi, she wears her hair in odango, though instead of the buns being round, they are styled to look like a rabbit's ears. Despite being 900 years old, she retains the appearance of a child due to the powers of the Legendary Silver Crystal. In the beginning of the series, she stood at the height at about 3'6", and after her awakening as Sailor Chibi Moon, continued to grow taller through the following arcs.

Pretty Soldier Sailor Stellar
After falling from a time portal, and onto Usagi and Mamoru, she threatens Usagi with a gun that turns out to be fake. She is later found and kept in care by Usagi after an attack by the Black Moon.

Over the course of the first arc, multiple attempts were made at kidnapping her. She is scared of Sailor Stellar, Sailor Galaxy, and sometimes, even Sailor Cookie, though she finds Cookie rather "more nice than the others".

Trivia

 * Due to a time paradox, the Chibiusa seen in Magical Star Princess Elyon is a completely new Chibiusa separate from the 30th Century version. This new Chibiusa retains the same appearance and personality as the 30th Century version.
