The power up sound comes from Dragon Ball Z, the anime adaptation of Akira Toriyama's Dragon Ball manga, where Saiyan warriors transform into the golden-haired, far stronger Super Saiyan form. Goku's first transformation against Frieza became one of the most iconic moments in anime, and its rising energy sound has since been reused in countless fan edits, reaction videos and gaming montages. It remains popular because it instantly signals a dramatic increase in power, making it a shorthand for levelling up in almost any context.
