Place it right after the boast that starts the rivalry, then follow it with the Vine Boom Sound Effect as the challenger steps forward, and save the Classic Punch Sound Effect for the first hit in the fight that follows.

This is a brief voice clip of a single speaker asking, “Are you challenging me?” in a flat, direct tone that turns a casual remark into a standoff. It lasts about a second and a half, just long enough for the question to land. The delivery feels tense, defiant and faintly amused, like someone has been underestimated and is inviting the other person to try their luck.
