Vecna is the humanoid, vine-covered monster villain from Stranger Things, transformed from the human boy Henry Creel (also known as 001). “Before and after” usually refers to how he looked as Henry versus his later, monstrous form as Vecna.

Before: Henry / 001

• Henry Creel starts as an apparently ordinary boy in the 1950s who moves to Hawkins with his family.
• He secretly possesses powerful psychic abilities, which he uses to torment his family and murders them, later becoming test subject 001 in Dr. Brenner’s program at Hawkins Lab.
• In the lab he appears fully human: shaved head, hospital-style clothing, and no visible mutation, though he wears a control device to limit his powers.

After: Vecna

• During a confrontation with Eleven, Henry is overpowered and blasted into the Upside Down, where his body is burned, torn apart, and gradually twisted into the skeletal, vine-entangled monster known as Vecna.
• As Vecna, he has grayish, decayed skin, roots and tendrils fused into his body, one oversized claw-like hand, and a deeply altered voice; he lives in the Upside Down and kills victims by invading their minds, breaking their bodies, and using their deaths to grow stronger.
