Chi-Chi

Chi-Chi is the wife of Goku and mother of Gohan and Goten, and also later the grandmother of Pan in the final chapter. She first appeared in Dragon Ball as a shy young girl, and in the Piccolo Junior saga as a teenager becomes tougher and tomboyish, yet still sweet. She is the Ox-King's daughter. She is very protective of her children.
== Pun of Name ==
Chi-Chi 's name is based on the word "Milk" and term "Udder" in Japanese. Chi-Chi is also slang for "Breasts", as it also probably a reference of breasts being a symbol of maternity. 
Even though this is stupid and gross it is true.
