Chichi is the Ox King's daughter, who also first appeared about the same time
as he did. After the first time we see Gyumao and Chichi they don't
reappear for a long time (in the manga). The next time we see Chichi,
she gets married to Goku. Therefore, she is also Gohan and Goten's
mother. Her distinguishing trait is her temper; she gets mad a LOT. She
is a very overprotective mother, which is probably justified in that her
son is constantly drawn into fights against some of the toughest people
in the universe.
