The kids of Hawkins may do a good job of showing their fear when they come face-to-face with the new "big bad" in season 3 of Stranger Things, but in reality, the cast had no idea what the creature looked like. "There was a man in a jumpsuit with a silver ball on his head and that's what we had to react to," Caleb McLoughlin, who plays Lucas, said in an interview with The Wrap. But despite not knowing what they were looking at during filming, they all agree on one thing: this new monster will make the Demogorgon seem like a teddy bear. Sadie Sink, who plays Max, calls it "definitely the biggest yet. I think the scariest, too."
Now the cast has seen the monster in its finished form, Sink says "it kind of looks like a combination of the Demogorgon and the Mind Flayer, with like the teeth and everything." Fans caught their first glimpse of the creature with the release of the final trailer for season 3, and quickly pieced together some theories concerning the monster's connection to a certain series 2 character we all loved to hate. Now season 3 is finally available on Netflix, you can binge your way to discovering if that theory is true.
