Dragon Ball Z is the long-running anime sequel to Dragon Ball, created by Akira Toriyama and produced by Toei Animation from 1989. The Portuguese-language opening, referred to online as DBZ Abertura, became the version generations of Brazilian and Portuguese viewers grew up with. Its rock arrangement and heroic lyrics made it inseparable from Goku's battles, and clips of the theme are still shared as a shorthand for charging up, nostalgia and classic shonen energy.
