Chi-Chi

Chi-Chi is the wife of Son Goku, and the mother of Son Gohan and Son Goten. She is often depicted as a sometimes nagging, overprotective but fundamentally well-meaning woman, who sincerely looks for her children and husband's well-being even when their views clash. She and Goku meet as children, and Goku promises to marry her thinking marriage is food. Several years later, she finds him at the 23rd Tenkaichi Budoukai, and despite confessing that he misunderstood what she had meant, he fulfills his promise and asks her to marry him. As she gets older, she disapproves of Goku's lifestyle, enough to ban Gohan from following in his foot steps, but due to the threats like Vegeta and Freeza, she is forced to let him train under Piccolo and Goku. She relaxes this with Goten by training him herself while Gohan is away for school. She has a wild temper and can react in violent anger over the slightest annoyance which means all of the Z Warriors fear her and try to avoid making her mad.
