Place this clip right at the attack beat in your edit, after a teleport sound to signal arrival and before a Za Warudo time stop for the follow-up freeze. A Mangekyo Sharingan cue works earlier for the villain build-up sequence.
About this sound
This short clip captures the sharp, humming slash of Goku Black's Ki Blade, the pink-purple energy weapon formed from his hand in battle. Lasting under two seconds, it feels intense and menacing, giving a quick hit of villainous power. It comes from the Dragon Ball Super anime, where Goku Black uses the blade in fights.
