Eight

if you had searched "Eleven" you would see a character from the show Stranger Things. This is also a character from Stranger Things. She was raised in Hawkins lab alongside eleven but escaped sometime before eleven. Like other test subjects, (yes there are others, I will touch on that soon.) she has her own unique power, which is making people see what she wants them to see. She appeared in a filler episode in season 2 where she tries to recruit Eleven into her criminal gang that hunts down Hawkins lab employees. I guess many people with psychic powers go through a weird phase when they are young where they are addicted to a specific brand because, in the book suspicious minds, young Kali (shoot I should have mentioned that was Eight's name) likes hostess cupcakes. Other test subjects include 3: Ricky, can control people by talking; 6: Francine, can see near future; 9: Jamie, can start fires; and 10: Marcie, no powers so far just Jamie's twin. There's also the Mk ultra test subjects: Ken, Gloria, Alice; who could see the far future, and Terry; Eleven's mom. Only 8 and Terry have appeared in The Tv series, the rest are from books. Eventually, Dr. Brenner relocated any remaining test subjects so that he could focus on Eleven, who had the most potential.
