The Xenomorph is the alien predator from the Alien franchise, first introduced in Ridley Scott's Alien in 1979, and its shriek has since become one of the most recognisable creature sounds in science fiction horror. Versions of the screech have circulated through films, video games and fan soundboards, where short clips are shared for edits, streams and memes. This variant is used online as a quick tension builder rather than a long roar, which keeps it useful for jump scares, boss reveals and horror-themed gaming moments years after the creature first appeared.
