Character Description
Puar is a fictional character in the Dragonball and Dragonball Z series.
Puar is an animal of an unknown species, although he resembles a mouse or a cat.
Puar is Yamcha's companion in the early Dragonball series. The two were originally a pair of thieves, searching for the Dragon Balls. When they found out that Bulma, Goku, and Oolong were searching for the Dragon Balls, they decided to follow them, and then once they have gathered them all they would steal them from them. However in the end, the two groups joined sides and since then, Puar became one of the heroes.
Puar is a shape shifter, much like Oolong, who they have claimed met each other at shape shifting school.
 Plot Involvement
In the beginning of the series, Puar helps the group a lot with his shape shifting abilities, but towards the end of the series, when the villains become more and more powerful, Puar quietly made the change to a background character, only appearing vaguely in some episodes and chapters.
