Put it at the end of a build-up, just before the reveal, then follow it with the FNAF Jumpscare Scream for a scare or the Inception Horn for a bigger dramatic moment, keeping the moon line as the warning that sets up the payoff.
About this sound
This is a very short spoken line, lasting about two and a half seconds, delivered in a low, ominous voice that sounds almost theatrical. It feels creepy and dramatic, like a warning whispered in the dark, which makes it both intimidating and funny when it lands unexpectedly. The line comes from Marvel Rivals and is associated with Moon Knight.
