She gets engaged to Goku in Dragon Ball, although Goku does not know it, and they get married at the end of Dragon Ball. She has two kids in Dragon Ball Z, Gohan and Goten, and one Grand Daughter, Pan, who is Gohan's daughter.
She is very protective of her family. She would not let Gohan train with his father and instead encourages him to become a scholar instead. Though this changed when her husband died, and she started to train her other son, Goten.
Chi-Chi is also a great martial artist, though can not stand against many of the main characters. She trained Goten while his father was in Other World.
She was first introduced as a shy and fearful girl, but later, as she gets older, develops a very tomboyish, tough and fierce personality, which sometimes causes her to have angry outbursts seen several times throughout the series. Despite this, she has shown her love for Goku and their sons many times throughout the series.
Chi-Chi is a tough woman with long straight black hair, a moderately curvaceous figure and a lighter skin color. As a child, Chi-Chi's appearance consisted of a blue bikini, pink gloves and boots, a green cape and her pink helmet. Chi-Chi kept this appearance until the Piccolo Jr. Saga where she wears a blue cheongsam (Chinese dress) with red pants, arm band, and shoes, white socks and a red sash. In this appearance she also wore her hair in a ponytail. Nearly all of the clothes Chi-Chi is seen wearing in her adulthood are Chinese dresses and martial arts uniforms.
In the first half of Dragon Ball Z, Chi-Chi's primary clothing was a purple dress that has an orange cloth tied on the top and a yellow sash. In the appearance Chi-Chi's hair was tied in a bun but she still had her hair coming down on the sides. Chi-Chi keeps her hair the same through the Androids Saga but she wears a Purple uniform with pink sleeves and pants. In the Buu Saga she wears a yellow uniform with a purple cloth tied on the back with all of her hair put into a bun and also wears white Chinese earrings. At the party celebration for the defeat of Kid Buu, she still wears her hair in a bun with long strands on hair framing her face, with pink lipstick, and wears a pink collared shirt, along with white pearl earrings and a pearl necklace and wears white slacks and black high heels.
Chi-Chi's appearance in Dragon Ball GT consists of a pink uniform with light green sleeves, a turquoise sash, violet pants and black shoes and gold Chinese earrings. Her hairstyle is much different and her hair is cut shorter as well.
