The Green Goblin is one of Spider-Man's oldest and most recognisable villains, first appearing in Marvel comics in the 1960s before Willem Dafoe's theatrical portrayal in the early Spider-Man films made his manic cackle famous worldwide. Clips of that laugh spread through online edits and meme soundboards, where it became shorthand for a villain enjoying a cruel plan. It remains popular alongside other Spider-Man villain sounds, including the Prowler and Spider-Man 2099, because a single cackle instantly tells viewers that trouble is coming.
