Dragon Ball Z (1989–1996) is a landmark anime series produced by Toei Animation, adapting the final 325 chapters of Akira Toriyama’s manga. As a direct sequel to the original Dragon Ball series, it follows an adult Son Goku, covering major sagas like Saiyan, Frieza, Cell, and Majin Buu. The "Z" was added by creator Akira Toriyama to signify the end of the story, as it is the last letter of the alphabet.
