Place it at the climax of a Persona edit, right after the Inception Horn and just before the reveal lands. Follow it with the FNAF Jumpscare Scream if the summon turns into a scare, keeping Thanatos as the turning point of the sequence.

This very short clip, under a second long, is named for Thanatos, the dark Persona from Persona 5. It lands with an ominous, dramatic weight that makes a moment feel larger and more threatening, like a powerful presence arriving just as the tension peaks. Credit for the original audio goes to Atlus.
