Not much information about this little white guy except that he's Tien's best friend and they usually fight together in battles. One of the battles they fought together was when Chiaotzu and Tien fought against the saiyans named Vegeta and Nappa. Chiaotzu threw himself on Nappa's back and self-destruct hoping to kill Nappa in the process, but it didn't work and he killed himself. Later he was wished back by the dragonballs.
