Chi-Chi: some say Chi-Chi is the most powerful woman on Earth (because she can control Goku). They met in Dragon Ball when they were at a young age. Her father, the Ox-King, trained her to be a formidable fighter in her own right. In Dragon Ball Z, Chi-Chi is mainly seen as a loving wife and mother, concerned and protective, perhaps even over-protective, of her family. She is always encouraging Gohan with his studies and often finds herself stubbornly at odds with Gohan's involvement with the martial arts. Chi-Chi would rather he be studying.

Oolong: Oolong is a shape-shifting pig who joined forces with the good guys. He attended the same shape-shifting school as Puar, but cheated to pass. Since he doesen't know the proper method, Oolong can only change shape for a short period of time and then has to rest. Not much of a fighter, he mostly hangs out at Master Roshi's home.

Puar: Puar is the devoted companion of Yamcha. They met Goku and Bulma together in the first series, Dragon Ball. Puar is a shape-shifting blue cat who went to the same school as Oolong. Unlike Oolong, Puar can change shape without having to stop and rest every few minutes, and can stay in the current shape as long as she wants.
