The Demogorgon first appeared as the main monster in the first season of Stranger Things, which premiered on Netflix in 2016. Designed as a tall, faceless predator that opens its head like a flower to roar and feed, the creature became the show's most recognisable horror icon. Clips of its growls and screeches were quickly isolated by fans and reused outside the series in horror edits, gaming videos and meme reveals. Its sound remains popular because it instantly evokes the Upside Down without needing any footage from the show.
