Chichi, known as Chi Chi in the Funimation dub, Chi-Chi in the Viz manga, and Milk in Latin-American TV, is the wife of Goku, and the mother of Gohan and Goten. She is very protective over the well being of her family, and wishes to remove them from Goku's lifestyle of fighting and constant conflict. She attempts to have Gohan focus on studying during his childhood, but this is interrupted by the constant threats to Earth. She later relaxes with Goten, even training him herself. As the daughter of the Ox-King, she is very strong in her own right, having made easily made it to the quarter-finals of the 23rd Tenkaichi Budokai. She and Goku first meet as children, and Goku promises to marry her, thinking marriage is a kind of food. She later confronts him to have him fulfill the promise, despite the misunderstanding. She is voiced by Mayumi Sho and Naoko Watanabe in Japan, and Laura Bailey and Cynthia Cranz in the Funimation dub. She will be played by Jamie Chung in the upcoming Dragon Ball live-action film.
Chi-Chi is often depicted as a sometimes nagging, overprotective but fundamentally well-meaning woman, similar to the stereotypical overbearing sh?nen mother. Though her power pales in comparison to most of the Z Fighters, she is still one of the strongest women in the world, and has been seen fighting well above the level of an average human on more than one occasion. She is also shown to be clumsy at times, such as when she hits Krillin in the head with a door, thinking he is Gohan.
In the introduction of Dragon Ball, Chi-Chi is introduced and is seen running away from a dinosaur who she later decapitates with her blade. Afterwards, she runs into Yamcha. After
getting knocked unconscious by Yamcha for attempting to attack him, he returns to her aid after realizing she is the Ox-King's daughter. When she first awakens she views Yamcha as a threat and gets ready to attack. He lies and says he loves her to keep her from hurting him. Because she is naive, she believes him. When she turns her back, Yamcha runs away. Soon she comes across Goku on his Flying Nimbus. While trying to ride the Flying Nimbus, Goku patted Chi-Chi's genitals with his foot to determine her gender (in the edited version, he merely tells her that she should put more clothing on). Brought up as the only daughter of Ox-King and living a secluded life, she jumped to the conclusion that Goku had a crush on her (after of course taking offense and kicking Goku who couldn't yet fly off the speeding cloud and then crashing herself) and fell in love with him. She tells Goku that when she becomes older, he will be the person to take her hand in marriage, with Goku believing that marriage is a tasty food.
After marriage, Chi-Chi became a supporting character to Goku and had her son Gohan. She is notable by emphasizing on Gohan's "academic achievement" rather than his fighting ability, as she was hesitant for Gohan to repeat Goku's habits of getting into danger, and she also didn't want Gohan to grow up without a proper education as Goku had. Therefore she often becomes frustrated when Goku decides to take Gohan to fights, so much that often Chi-Chi is willing to go to battle herself to defend her son, though she's always restrained by some of the other characters to keep her from getting herself killed; nonetheless, it is often implied that Chi-Chi is proud of Gohan whenever he does fight, but refuses to admit it. Inevitably, Gohan had to work hard on both his human identity as well as his academic skills. Nonetheless, Chi-Chi apparently grows more accepting of Gohan fighting, as she allows him to train for the Androids and participate in the Cell Games. The very last chapters of the manga stated that Gohan had become a scholar and thus did not participate in the final World Martial Arts Tournament of Dragon Ball Z. Although Chi-Chi disapproves of fighting, it is stated by Goten in the DBZ Game Boy Advanced Game Buu's Fury that she taught him how to go Super Saiyan.
