Every Monster on "Stranger Things" Explained

Another season of "Stranger Things" means another Demo-monster variation! In season four, it's the "Demobats," small, flying versions of the Demogorgon and Demodogs from previous seasons. We meet them in the Upside Down (no surprise), when Steve encounters them after getting sucked into the demonic dimension. While they might be small(ish), they're still powerful and terrifying, especially when they swarm.
