What’s more, fans believe the upcoming new foe could be something that has already been alluded to in the series.
Speaking on the Stranger Things Reddit, one fan suggested: “Really hope they make a new monster for the new season.
“Mind Flayer and Demogorgon got enough representation already to the point where they’re mob characters even when they’re the season’s boss.”
Another suggested that, perhaps, the Thessalhydra would be making an appearance in the show in season four.
