Demogorgon is one of the main antagonists in the first season. He was a predatory humanoid creature that ended up in Hawkins, Indiana in November 1983. The creature originated from a parallel dimension known as the Wrong Side, or the Back Side. When Eleven, a test subject at Hawkins National Laboratory, made interdimensional contact with him, a gateway between dimensions opened in the laboratory. The creature entered our world, straining Hawkins for about a week. He abducted various inhabitants and dragged them to the Seamy Side, usually killing them or leaving them to eat later.
