This sound refers to the Kaio-ken technique from Dragon Ball, where Goku boosts his power at great strain to his body. The phrase “Kaioken Times 10” became especially popular in anime fandom and short-form edits because it clearly signals a dramatic jump in intensity. Online, creators use it as a quick audio cue for power scaling, clutch moments, and exaggerated transformations. Its staying power comes from how instantly recognizable the line is to fans and how easily it fits hype-focused meme editing.
