The world of Stranger Things is filled with monsters from a dimension called the Upside Down, and the show’s characters spent a long time trying to figure out where they came from. Season 4 revealed that a villain named Vecna – originally known as Henry Creel – was responsible for creating all of these creatures. In one episode, we learned about Henry’s father, Victor Creel, who was portrayed by Robert Englund, famous for A Nightmare on Elm Street. Englund will be back for the first Stranger Things spin-off, Tales from ’85, but this time he’ll be providing the voice for a character named Cosmo. So far, that’s all we know about the role.
