Place this clip at the start of a villain sequence, then follow it with a bass drop sound effect for the reveal and save the Darth Vader No Sound for the hero's panicked reaction afterward to flip the power dynamic.
About this sound
This is Bane delivering his 'you think darkness is your ally' line in a slow, mask-filtered voice over about two and a half seconds. It feels ominous and theatrically threatening, like a villain calmly claiming an advantage no one else understands. The clip comes from The Dark Knight Rises, with Tom Hardy playing Bane.
