Place it at the reveal beat, after a normal intro and before the main action starts. Follow it with the Mangekyo Sharingan Sound Effect for a second power layer, or precede it with JoJo To Be Continued when you want the scene to freeze on the threat.

A four-second voice clip of Itachi Uchiha tied to his Mangekyo Sharingan. It feels cold, tense and quietly threatening, carrying calm menace rather than a joke. The clip comes from Naruto, where Itachi is known for calculated, dangerous reveal moments.
