Dragon Ball Z follows the adventures of Goku who, along with his companions, defends the Earth against villains ranging from conquerors, androids, and other creatures. While the original Dragon Ball anime followed Goku from childhood to adulthood, Dragon Ball Z is a continuation of his adult life, but at the same time parallels the maturation of his sons, Gohan and Goten, as well as the evolution of his rivals Piccolo and Vegeta from enemies to allies.
