Demogorgons come from the Upside Down , a parallel, hostile dimension in the Stranger Things universe, and the individual monster in season 1 crosses into Hawkins after Eleven makes psychic contact with it and unintentionally opens a gate.

In Stranger Things

  • The Demogorgon is a predatory humanoid creature native to the Upside Down, an alternate dimension mirroring our world in a dead, corrupted form.
  • When Eleven reaches out telepathically in a sensory deprivation experiment, she encounters the creature, and this contact tears open a gate between the lab and the Upside Down.
  • The Demogorgon then physically enters Hawkins through this gate and begins hunting, killing, and abducting people, dragging some victims (like Will) back into the Upside Down.

Name vs. Origin

  • The kids call it “Demogorgon” after the two-headed demon from the Dungeons & Dragons Monster Manual, but that tabletop demon is unrelated to its in‑universe biology or origin.
  • Outside Stranger Things, “Demogorgon” historically comes from a likely scribal error of the Greek word for “demiurge,” which later writers turned into the name of a primordial god or demon of the underworld.

So where do they “really” come from?

  • In canon, Demogorgons are simply part of the Upside Down’s ecosystem: an apex predator species spawned and evolved in that dimension’s toxic, spore‑filled environment.
  • The show leaves their deeper creation (who made the Upside Down, why it exists, how the species first emerged) deliberately mysterious, so any further “origin story” beyond that is speculation or fan theory.
