Jane (Eleven) Hop

Jane Hopper (born Jane Ives), also known as Eleven or El, is a main character in Stranger Things. She is portrayed by Millie Bobby Brown. Jane was born with special psychokinetic abilities; Jane's mother, Terry, was experimented upon in the controversial government program known as "MKUltra", which, by accident or by Dr. Martin Brenner's design, affected Jane in the womb. Upon her birth, Jane was immediately kidnapped by Dr. Brenner, and brought to Hawkins National Laboratory. Jane was designated "Eleven", as one of many in Brenner's series of child test subjects.
