Chi-Chi is the princess of Fire Mountain and the daughter of the Ox-King. She was first introduced as a shy and fearful girl, but later, as she gets older, develops a very tomboyish, tough and fierce personality, which sometimes causes her to have angry outbursts seen several times. She is often depicted as a sometimes nagging, overprotective, controlling, tough and fundamentally well-meaning woman, similar to the stereotypical overbearing shōnen mother.
