Goku is the main hero of Dragon Ball, the long-running Japanese anime and manga series created by Akira Toriyama, and his light, good-natured laugh has become a familiar part of his optimistic character. Short clips of his voice have circulated for years through anime edits, meme videos, and soundboards, where fans reuse the laugh as a quick, positive reaction. It remains popular because it is instantly recognisable to anime fans, easy to drop into a joke, and works as a friendly alternative to harsher anime reaction sounds.
