Place it after a character's line lands and before the reaction shot cuts away. Pair it with the Imperial March sound effect for a bigger villain entrance, or follow it with the Law & Order Dun Dun for a mock-serious verdict.
About this sound
This is an 18-second violin-led theme linked to Homelander, built around tense, dramatic strings that build slowly rather than burst. It gives a listener a cold, uneasy feeling of menace and barely held anger, like a smile hiding a threat. The cue comes from The Boys, the superhero satire series that premiered in 2019.
