Every horror project eventually needs the laugh — that drawn-out cackle from behind a wall of bubbling beakers, half triumph and half something gone permanently wrong upstairs. These 13 mad-scientist laugh clips work the full register: maniacal cackles climbing two octaves, low evil chuckles that stay in the chest, the triumphant guffaw of someone whose lightning machine just worked, and the quieter sinister giggle that's actually scarier than any of the louder takes.
Animation and cartoon villain work reaches for the bigger cackles — broad gesture matches broad performance, and pitch-shifting up a couple of semitones lands the comedy. Indie horror games use the quieter giggle as off-screen presence; it implies a watcher without showing one. Halloween edits and parody trailers pull the triumphant variant for the moment the plan comes together on screen.
