This sound comes from Dragon Ball Z, the long-running anime series where Saiyan warriors such as Goku transform into more powerful Super Saiyan forms during battle. The transformation sequence, with its charging energy and dramatic scream-like surge, became one of the show's most recognisable moments and was widely shared in fan edits, AMVs and soundboards. Because the power-up is instantly understood even by viewers who have not watched the series, creators still reuse the clip to signal a sudden boost in strength, confidence or intensity.
