The headstrong wife of Goku, some say Chi-Chi is the most powerful woman on Earth (because she can control Goku). Her father, Ox-King, trained her to be a formidable fighter in her own right. In Dragon Ball Z, Chi-Chi is mainly seen as a loving wife and doting mother, concerned and protective, perhaps even over-protective, of her family. She is always encouraging Gohan with his studies and often finds herself stubbornly at odds with Gohan's involvement with the martial arts.
