When Stranger Things began, Eleven (Millie Bobby Brown) was a total mystery. Aside from her telekinesis, one of the first observable facts about her was her numeral designation. If she was “Eleven,” then it followed there must have been 10 before her, right? Stranger Things 2 introduced us to Kali (Linnea Berthelsen), a.k.a. “Eight,” but that leaves others — and what better way to explore those stories than with the Stranger Things kids’ beloved comic books? EW can exclusively announce that Dark Horse’s next Stranger Things comic will be a prequel focused on another of Eleven’s predecessors: Six.
