Dragon Ball Z is a Japanese anime television series produced by Toei Animation. It is the sequel to the Dragon Ball anime and adapts the latter 325 chapters of the original 519-chapter Dragon Ball manga series created by Akira Toriyama which ran on the Weekly Shounen Jump from 1988-1995. Dragon Ball Z aired in Japan on Fuji TV from April 26, 1989 to January 31, 1996, before getting dubbed in territories including the United States, Canada, Australia, Europe, India and Latin America. Dragon Ball Z follows the adventures of Goku who, along with his companions, defend the Earth against villains ranging from conquerors, androids and other creatures. While the original Dragon Ball anime followed Goku from childhood to early adulthood, Dragon Ball Z is a continuation of his adult life, but at the same time parallels the lives of his sons, Gohan and Goten, as well as the development of his rivals Piccolo and Vegeta from enemies to allies. Due to the success of the anime in the United States, the manga chapters comprising its story were initially released by Viz Media under the title Dragon Ball Z.
