Eleven

Eleven, known primarily by the number eleven due to her numerical code name and lack of known birth name, is a character from the TV series Stranger Things. She is an adolescent girl with psychic abilities, including telekinesis, telepathy, and the power to move through the Upside Down, a parallel dimension filled with danger. Eleven's early life was marked by harsh treatment in a secret government lab where she was used as a test subject, causing her to develop an intense fear of her captors. She is fiercely protective of her friends and demonstrates courage, compassion, and determination in the face of supernatural threats. She has a complex relationship with her own powers and often wears her hair long to cover the bald spot on her head, a result of those experiments. Eleven is close to her adoptive family, especially Mike Wheeler, and forms deep bonds with her friends in Hawkins, Indiana. Her arch-nemesis is the Mind Flayer, a creature from the Upside Down that is recurrently trying to invade the normal world.
