Who ever doesn't know what the hell DBZ (Dragonball Z) is you need to watch more TV. This show is a struggle to defeat enemies from other places. Goku is the main character who is also the first to become a Super Saiyin (a saiyin being a human with a monkey tail). Dragonball is when Goku is a boy and /GT is when most of the saiyins come in and power levels rise. This whole series gets over a 10.
