Season four of Stranger Things saw its scariest villain yet: Vecna.
Played by Jamie Campbell Bower, each prosthetic was glued to his skin with medical adhesive by prosthetics designer Barrie Gower and his team.
For the finishing touch, Vecna was covered in "glossy slime to make him really, really glossy and wet looking," according to Gower.
With 2425 appliances in total, Vecna is ready to head to the Upside Down!
In this exclusive image, you'll see an up close look at the prosthetics done to create the blinded Victor Creel, played by Stranger Things newcomer and Nightmare on Elm Street legend Robert Englund.
