Stranger Things has given us some interesting characters over the course of its run. While some of them turn out to be substantial, some are forgotten over time, and such was the case with 008 or Kali. However, as it turns out, she was not done with Stranger Things and has made a return to Stranger Things Season 5, but not exactly in the way one would have expected. In Episode 4, Eleven finds Kali locked up in a vault, and now, it goes without saying that she is going to return to the main events of the series. So, if you don’t recall a lot about this character, here is all you should know about 008/Kali’s backstory or origin before she takes her place in Stranger Things Season 5.
Who Is Kali or 008 in Stranger Things?

Kali Prasad was a test subject, similar to Eleven at Hawkins National Laboratory. She was abducted as a child and was assigned the number 008 at the Hawkins Lab. She and eleven were both test subjects in the lab’s Rainbow Room.
Season 2 of Stranger Things told us that she and Eleven developed a close relationship with each other, going to the extent of calling each other “Sister”, but were separated after Kali escaped from the facility during the massacre done in the laboratory by Henry, now Vecna.
We also see in Stranger Things Season 2 that Eleven trained with Kali to use her powers better and even considered joining Kali in her quest for revenge; however, Eleven ultimately decided to go back to Hawkins to help her friends.
What Are Kali’s Powers in Stranger Things?
Even though Kali and Eleven were test subjects for the same experiment, their powers are very different from each other. While Eleven has telekinetic abilities, Kali has the power to create realistic illusions and can make anyone see and believe whatever she wants them to.
Even though we got to see Kali use her powers for a bit, we never got to see a lot of it, and now that she has returned in Stranger Things Season 5, there is a good chance that we could get to see more of them in action in future episodes.
As of now, it is hard to say the extent of her character if Eleven manages to free her from the vault, but Doctor Kay was certainly conducting experiments on Kali and probably wanted to capture Eleven for the same reason, so her powers could be weaker as compared to what we saw in Season 2. So, let’s wait and see what the future holds as new episodes come out way on December 25, 2025.
