Kali (008) from Stranger Things is about 20–21 years old in Season 2 and is later listed as 23–24 years old by Season 5 in the show’s timeline.

Who Kali Is In Stranger Things

  • Kali Prasad, also known as 008 , is a former Hawkins Lab test subject with illusion-based powers, letting her alter what people see rather than move things like Eleven does.
  • She appears primarily in Season 2 as a kind of “fork in the road” for Eleven, representing a harsher, revenge-driven path shaped by trauma and isolation.

How Kali’s Age Is Described

  • Fan and wiki timelines place Kali at around 9–11 years old in the 1974 flashbacks , when she and Eleven are children in the lab.
  • Those same timelines list her as 20–21 during the events of Season 2 , which is why she feels notably older and more experienced than Eleven on-screen.

Later Timeline (With Season 5)

  • Updated character breakdowns and fan-maintained canon notes age Kali to 23–24 years old by Season 5 , tracking with the jump forward in the series’ in‑universe years.
  • This keeps her a few years older than characters like Nancy and Steve, fitting her more independent, adult life away from Hawkins.

TL;DR: If you’re wondering “how old is Kali from Stranger Things?” the best-supported answer is:

  • Child flashbacks: about 9–11
  • Season 2: 20–21 years old
  • Around Season 5 era: 23–24 years old
