Literally the worst character in Dragonball Z.
I don't think he ever won a fight. He also got dumped by Bulma. The only good thing about him is that some people mistake him for Gohan which just goes to show he can't think of an original look either.
If you want a good Yamcha watch DragonBall.
DBZ Fan1: Think Yamcha will beat Android 18?
DBZ Fan 2: Probably not, he's getting more useless each episode.
