The Demogorgon, also known as the Monster from the show Stranger Things, was a predatory humanoid creature that entered Hawkins, Indiana in November 1983. The creature originated from the parallel dimension known as the Upside Down. When Eleven, a child test subject from Hawkins  Laboratory with psychokinetic abilities, made trans dimensional contact with the creature, a gate between dimensions opened at the lab. The creature then set foot in Hawkins, and began hunting, killing and kidnapping various local townspeople.
