Chi-Chi's mother was the wife of the Ox-King. Although she is mentioned a few times, her only appearance is in in a painting seen in the anime episode "Dress in Flames" which shows her sitting in the Ox-King's hand and holding Chi-Chi as an infant.
In the painting, the face of Chi-Chi's mother is not shown since it is blocked by decorations, but it can be seen that she has the same hair style as Chi-Chi and dresses the same way Chi-Chi does when she becomes older. She is shown wearing a turquoise cheongsam with purple pants underneath, and pink socks and shoes. In the painting showing her, she is similar in size to the Ox-King's hand.
She lived with the Ox-King and Chi-Chi before Pleasant Mountain caught fire. She died of an illness the same year Chi-Chi was born. Her wedding dress becomes the only thing left to remember her by.
Video game appearance
Chi-Chi's mother is also seen on the painting in Ox-King's castle in Dragon Ball Z: Attack of the Saiyans.
