Place it at the peak of a villain reveal, after the Inception Horn builds tension and before the Danger Alarm Meme Sound signals trouble, then cut to the FNAF Jumpscare Scream for a sudden scare.
About this sound
This under-four-second Japanese voice clip has a deep-voiced villain declaring himself the messiah, then bursting into loud, theatrical laughter. It feels arrogant and unhinged, funny because the speaker sounds completely serious about his own godhood. It comes from Mega Man Zero 3, the 2004 Game Boy Advance game in Capcom's Mega Man Zero series.
