The official teaser trailer for Season 5 previews a final battle with Vecna, whose complex origin story is the focal point of the play "Stranger Things: The First Shadow."

The trailer doesn't show Vecna's full face, but the Season 5 poster reveals it’s partially hidden in a red cloud. The cloud obscures one of his eyes, hinting at possible physical damage. This detail suggests he may have lost the eye during the Season 4 battle.

Did you know that Stranger Things was originally going to kill off two fan-favorite characters and that a Bridgerton star lost out on a major role?

Vecna returns with a terrifying new look in Stranger Things Season 5. Could he be hiding inside Will Byers? A dark theory suggests so.

Stranger Things is still pulling in huge numbers on Netflix, and fans are clearly getting ready for the show’s big ending. According to Netflix’s latest Engagement Report, the series picked up a massive 404.10 million viewing hours in just the first half of 2025. This covers all four seasons of the hit sci-fi horror drama.

Stranger Things 5 revealed the first look at Terminator icon Linda Hamilton in the final season's first official trailer, which dropped Wednesday. The actress, also known for Dante's Peak and Children of the Corn, arrives in the role of Dr. Kay, who's surrounded by her own personal SWAT team.
