The clip comes from Dragon Ball Z, where Goku first turns Super Saiyan during his battle with Frieza on Planet Namek after Krillin's death pushes him past his breaking point. That moment became one of anime's most famous power-ups, and fans have clipped the scream ever since for edits on YouTube, TikTok and other short-video platforms. It still works because the yell is instantly recognisable to anime fans and signals a dramatic turning point without needing any dialogue or explanation.
