As a child Chi-Chi was very shy and often always thought about who she would marry. Despite being the daughter of the Ox-King, who had a reputation of being terrifying she was shown to be the opposite of him as she was shown to be of pure heart by being able to ride the Flying Nimbus. During fighting, she is often scared and defeats her opponent while crying.
Chi-Chi's personality changed when she became an adult especially after marrying Goku and having her son Gohan. She is often depicted as a sometimes nagging, overprotective but fundamentally well-meaning woman, similar to the stereotypical overbearing shōnen 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 mentally clumsy at times, such as when she hits Krillin in the head with a door, thinking he is Gohan. Although Chi Chi often seen yelling at Goku over fighting, or Gohan over his school work, it can be argued that she loves Goku and her family very much. This is shown at the end of the Buu Saga when she is brought to tears just over the thought of finally getting to live as a family of four with Goku, Gohan, and Goten.
