Chi-Chi is mother to Gohan and Goten and the spouse of Goku. She feels very strongly about Gohan's studies and will stop at nothing to get him to continue his work; Chi - Chi when mad can get a good amount of power (for a woman) that will defend off some people. She mainly spends her time worrying about Gohan's academics. No matter how powerful Goku becomes, he still is very subserviant to his worrisome wife.
