Jean Grey

Jean Grey, the famous red head from the X-men is one of the world's most powerful telepaths. She can read minds, control the thoughts of others, and move objects with a thought. Jean has even more power buried deep within her, that emerged with her dark side when she became the Dark Phoenix.

Jean Grey had transformed several significant times in her life. She had been a young adult known as Marvel girl, who had almost no control over her powers. Then she'd worn a Green dress and yellow mask. Later in life she'd been known as just Jean Grey, and was one of the most powerful members of the X-men. Then, when her power's went mad she became the Dark Phoenix, a twisted version of herself. Later on she'd been entangled with the on again off again villain Emma Frost, the two competing over the same love interest, Cyclops.
