Stranger Things has always focused on the threat of the unknown. All manner of beasts and monsters dwell in the Upside Down, and the fifth (and final) season of the Netflix series will have to solve this realm’s mystery once and for all, ideally while severing its connection to the real world in the process. But Season 5 also has a lot more on its plate, and the return of Stranger Things’ Big Bad, Vecna, is just one of many conflicts in store for the heroes of Hawkins, Indiana. The supernatural will always take center stage, but Season 5 is also set to introduce another threat in the form of Dr. Kay, played by Terminator star Linda Hamilton.
The Stranger Things team has worked hard to keep Dr. Kay under wraps, but the closer we get to the Season 5 premiere, the more we learn about this new antagonist. A recent profile in Time revealed that Kay leads a “sort of mercenary regime” called the Wolf Pack, and they’ll be hunting Eleven (Millie Bobby Brown) for some yet-unknown reason. As for Kay herself, showrunners Matt and Ross Duffer recently sat down with Empire to reveal a bit more about her, and how she’s the exact opposite of what we’d expect from Linda Hamilton.
