About this sound
This is an 18-second speech from Vegeta where a controlled, threatening delivery builds into an unrestrained emotional break as he says something inside him snapped. It feels tense, frustrated and cathartic, like the exact second restraint collapses. The clip comes from Dragon Ball Z.
