Terminator star Linda Hamilton makes her debut in the final season of Stranger Things as Dr. Kay, a gun-toting government operative hunting Eleven while battling Demogorgons.
The first teaser for Stranger Things Season 5 has revealed Linda Hamilton in action as Dr. Kay, a new character likely tied to the U.S. military. Known for her iconic role as Sarah Connor in The Terminator films, Hamilton brings her action-hero background to Netflix’s hit series. The teaser shows her armed and leading a team against creatures from the Upside Down, sparking theories about her role as a potential antagonist.
Who Is Dr. Kay in Stranger Things Season 5?
Hamilton’s character, Dr. Kay, appears to be a high-ranking government agent or scientist involved in the military quarantine of Hawkins. The teaser briefly shows her with armed operatives, suggesting she may be hunting Eleven (Millie Bobby Brown) while also fighting Demogorgons. Her title of “Doctor” hints at a possible connection to Dr. Martin Brenner (Matthew Modine), the scientist who experimented on Eleven.
“It was a very long haul. We took a year to shoot eight episodes, so I’ve never been on a project for a year.”

Hamilton’s extensive filming schedule suggests her role is significant, not just a brief cameo. Some fans speculate she could be the main villain of the final season, replacing Vecna as the primary threat. Others believe she might be an ally who later turns against the Hawkins group.
Linda Hamilton’s Reaction to Joining Stranger Things
Despite being a fan of the show, Hamilton admitted that being cast “ruined” the series for her because she avoids watching projects she’s involved in.
“I’ve watched every season with relish. I just love it. So it’s kind of, like, imposter syndrome where I don’t [feel that I] fit in there. That’s a whole world set in the ’80s.”
“When you really buy into something, you don’t see yourself in it. So I think in a way, it kind of ruined the show for me.”

Stranger Things Season 5 Release Schedule
The final season will be released in three parts:
- Volume 1 (Episodes 1-4) – November 26, 2025 (Thanksgiving)
- Volume 2 (Episodes 5-7) – December 25, 2025 (Christmas)
- Volume 3 (Episode 8 – Finale) – December 31, 2025 (New Year’s Eve)
The story picks up in fall 1987, nearly a year after Season 4. Hawkins is now a military-controlled zone, with Eleven in hiding and Vecna’s whereabouts unknown. The final battle will require the entire group to unite against a “darkness more powerful and more deadly than anything they’ve faced before.”
Why Linda Hamilton’s Casting Matters
Hamilton’s addition continues Stranger Things’ tradition of casting ’80s icons, following stars like Winona Ryder, Sean Astin, and Paul Reiser. Her role as Sarah Connor in The Terminator makes her a perfect fit for the show’s nostalgic tone.
Fans are excited to see how her character fits into the final battle against Vecna (Jamie Campbell Bower) and the Upside Down. With her action-packed introduction, Dr. Kay could be one of the most memorable new characters in the series.
