Chi-Chi is the wife of Son Goku, she is a supporting character in the series, originally, she just has a bit of a temper, but as time went on, she became a nagging wife who nearly does not care about the world getting destroyed.
She originally just had a bit of a fiery temper, but as time went on, she became an overprotective, nagging wife and mother who wanted Gohan and Goten to become scholars, not caring if the world gets destroyed.
Her screaming gets annoying fast.
She called Goten a "monster" when he accidentally unlocked Super Saiyan during a training session.
She cannot take even the slightest bit of criticism. One example is when Krillin's ex-girlfriend Maron called her a "bore" and she beat her up for it.
She has no empathy for her friends. One example includes not allowing Gohan to accompany Bulma and Krillin on their journey to Planet Namek so they could collect the Namekian Dragon Balls and wish their fallen friends back.
Her suicidal carelessness. For example, when Super Buu bragged about killing Gohan, she slapped him across the face despite Piccolo repeatedly warning her not to, prompting an enraged Buu to turn her into an egg and crush her to death.
She's a massive hypocrite. She claims that Pan should act more lady-like, yet she acts tomboyish herself.
Despite her anger, she has a point that Goku needs a job to survive rather than just fighting evil.
There are some Dragon Ball fans who like her.
She does care about her family at times.
She has a sad backstory about her mother dying from an unknown illness shortly after giving birth to her.
She used to be tolerable in the original Dragon Ball series.
Her dislike of Piccolo may be somewhat understandable given that Piccolo almost killed Goku and kidnapped her son for a year.
Her name means "milk" in Japanese.
Two alternate timeline versions of Chi-Chi met untimely ends: the Chi-Chi from Future Trunks' timeline committed suicide after Future Gohan was killed by the Red Ribbon Androids, and the Chi-Chi from Goku Black's timeline was decapitated by Black with a ki blade.
She might be the example of an Asian tiger-mom who only pushes her children because she wants the best from them.
Akira Toriyama has stated that Chi-Chi is his least favourite Dragon Ball character.
