Place it at the very start of the face-off, just before the two sides are shown together, then cut to Enemy Spotted as the challenger is noticed and finish with the Inception Horn once the standoff is fully set up.
About this sound
This two-second voice clip delivers the line 'Oh? You're approaching me?' in a calm, menacing tone, with a measured pause that makes the question sound like a dare. It feels tense and theatrical, turning a simple approach into a dramatic standoff. The line comes from JoJo's Bizarre Adventure: Stardust Crusaders, from the confrontation between Jotaro Kujo and Dio Brando.
