Place this clip right at the duplication reveal, then follow the action with a teleport sound effect for the exit and a JoJo To Be Continued sting if the scene freezes on the result for a cliffhanger ending.
About this sound
This clip is Naruto delivering the spoken line "Kage Bunshin no Jutsu," the Japanese name for the Shadow Clone Technique, in a short forceful voice take lasting about three and a half seconds. It feels dramatic and energising, turning a simple moment into a sudden power-up. It comes from Naruto, the manga and anime series about ninja battles and named techniques.
