The facehugger is the small, spider-like creature from the Alien films, first introduced in Ridley Scott's Alien in 1979, where it attaches to a host to begin the alien life cycle. Its unsettling design made it one of the most recognisable monsters in science-fiction horror, and clips of its movement and sounds have circulated for years on soundboards, fan edits and reaction videos. Creators still reach for it because it instantly signals danger, invasion and body horror in under two seconds.
