Stranger Things season 5 is highly anticipated, with a new poster depicting the resurrection of Vecna, the villain introduced in season 4. The artwork by Axel Almirón shows Eleven, Mike, and other characters watching as Vecna emerges from the Upside Down. Although defeated in season 4, Vecna's return is likely, given that he was not definitively killed. With the success of his plan and potential allies like Demogorgons and the Mind Flayer, Vecna is set for a major comeback in the final season. Stranger Things season 5 is expected to air on Netflix in 2025.
