The trailer for Season 3 of Stranger Things features superpowered pranks, teenage angst, and a first trip to the mall! But the thing that has people talking is the nasty looking monster at the end. What is that thing?
While the trailer doesn’t offer any concrete information, we have a few clues to go on.
Dungeons and Dragons
Each season features one monster in particular that Mike, Dustin, Lucas, and Will, being the dorks that they are, name after a D&D monster that has similar attributes. Season 1 gave us the Demogorgon, and Season 2 the Mind Flayer (and the Demogorgon spin-off, the Demodog). This new beast stands apart from the rest, and IGN’s resident D&D nerd Nick Limon pegs it as what could be a Tarrasque.
