Place this clip at the reveal beat in a gameplay edit, after an enemy spotted cue builds the approach and before a jumpscare scream hits for the reaction shot that follows the entrance.
About this sound
The clip is built around Metal Sonic appearing, presented as a game moment centred on the metallic rival. It gives an eerie, tense feeling, like an opponent has just arrived uninvited and the scene has shifted into a confrontation. That shift is what makes the appearance feel menacing rather than heroic.
