Kaioken is a power-multiplying technique from the Dragon Ball series, most closely associated with Goku, who shouts its name as he pushes his body beyond its normal limits. The elongated, stretched-out pronunciation in this clip mirrors how the call is delivered in anime fight scenes, where the shout itself becomes part of the transformation. As Dragon Ball clips circulated through anime edits, reaction videos, and meme soundboards, the Kaioken yell became shorthand for a sudden surge of effort, which is why creators still reach for it for comebacks and power-up moments.
