Jean Grey was ten years old when her parents brought her into the care of Charles Xavier. Her telepathic powers had manifested themselves after she experienced the emotions of a dying friend. Charles helped her by erecting psychic shields in her mind that prevented her from using her powers until she was mature enough to control them.
Jean Grey was a young girl with a bright future ahead of her when Henry McCoy arrived, planning to take the original X-Men into the future to stop Scott Summers from causing a civil war. The time-travel shocks her telepathy into action a year before it was supposed to. Now an untrained psychic, Jean looks to her future mentee Kitty Pryde for help in containing her new and overwhelming powers.
