Chi-Chi
Chi-Chi is Goku's wife and Gohan's mother. She is often pressuring Gohan to study and Goku to get a life. She is, in general, a housewife. She is always trying to choose Gohan's future for him, and in more cases than one, fails. She didn't want Gohan to fight in battles, didn't want him to hang out with his fathers friends like Picollo and Yamacha, and gives him no freedom.
