The Prowler is Aaron Davis, the masked antagonist and uncle of Miles Morales in Spider-Man: Into the Spider-Verse from 2018. His appearances in the film are paired with a harsh, distorted musical sting that stands out from the rest of the soundtrack, which is why clips of it spread quickly as a standalone Prowler Sound Effect. Editors on TikTok and YouTube began using it as a shorthand for danger, a villain reveal or an approaching threat, and it remains popular because it is instantly recognisable even to viewers who have not seen the film.
