An otherworldly monster
The Demogorgon is an important character in the series Stranger Things set in the 1980s in a small town in the United States. At the beginning of the first season, young Will disappears, having been kidnapped by a strange creature. His friends search for him by going back to the forest that the young boy walks through to get home and come across a young girl who has escaped from a lab she grew up in and has telekinetic powers. We begin to understand that he has been taken to a sort of nightmarish parallel world. In this world live creatures that the children decide to call demogorgons in reference to their role playing games. These creatures feed on all living things but their parallel world is cold and deserted, so our world is particularly interesting for them.
