Which actor portrays the adult form of Vecna in Stranger Things season 4?

Jamie Campbell Bower portrays the adult form of Vecna in Stranger Things season 4. He plays the character’s transformed adult identity as well as Henry Creel and the Hawkins Laboratory subject known as One.

Season 4 gradually reveals that Vecna is not a completely separate monster. He was originally Henry Creel, a human with powerful abilities who became One after being taken into Dr. Brenner’s experiments. After Eleven defeats him, he is banished to another dimension and eventually transformed into the being known as Vecna.

Bower’s performance combines acting, voice work, movement, and extensive prosthetic makeup. The adult Vecna design was created largely with practical effects, including a full-body prosthetic appearance of scarred skin, exposed organic textures, and Upside Down-like growths.

The role is sometimes confused with Joseph Quinn, who plays Eddie Munson, or David Harbour, who plays Jim Hopper. Paul Reiser appears as Dr. Sam Owens. Bower is the actor specifically associated with adult Henry Creel, One, and Vecna.
