Chaozu

餃子

Chiaotzu appears to be a small, doll-like human with plain white skin and red cheeks; his name is derived from the food jiaozi. Upon his first introduction, Chiaotzu is a student of the Crane Hermit (a rival of Master Roshi) and the constant companion of fellow student Tien; however, he quickly amends his ways and joins Goku and his friends. Although not outstanding in physical prowess compared to other superhuman warriors in Dragon Ball, Chiaotzu possesses considerable potency in psionics, particularly in psychokinesis. Chiaotzu is not very well educated, as demonstrated in the Tien Shinhan Saga. In one instance, Krillin was called "squid" because of his shaved head. Krillin became angry and stated that Chiaotzu was also bald. But Chiaotzu removed his cap, revealing ONE hair on top of his head (which made Krillin very angry). Chiaotzu lost the battle in the 22nd Martial Arts Tournament due to Krillin's maths knowledge.
Chiaotzu's importance in the series rapidly diminishes after his introduction in the Tenshinhan Saga, where he is a major character. He is a minor character in the subsequent Demon King Piccolo, Piccolo Junior, and Vegeta sagas, and is more-or-less a background character for the others. Chiaotzu also has a prominent role in the Dragon Ball movie "Mystical Adventure."
