Place it just before the confrontation in your edit, after Enemy Spotted has identified the target and the rival is already in view. Follow it with Bomb Has Been Planted to turn the warning into an immediate objective, keeping the threat as the turning point between spotting the rival and the action that follows.
About this sound
This clip is a single spoken threat, 'I'm going to tear you apart!', delivered in a sharp, menacing voice and lasting just under two seconds. It feels tense and intimidating, with the blunt delivery making the warning land hard. In the right moment it also turns comic, because the threat is so direct and over the top that it sounds like a villain losing patience.
