Place this clip at the turning point of your edit, after the threat is shown and before the fight begins, then follow it with Giorno Giovanna Theme for the payoff. For a villain showdown, open with Za Warudo Time Stop before the vow to set up the confrontation.
About this sound
This is Goku delivering his defiant line 'I will not let you destroy my world' over about twelve seconds, his voice growing fiercer and more resolute as the vow builds. It feels heroic and tense, like a turning point where holding back ends and protection begins. The line comes from Dragon Ball Super.
