Jean Grey is a mutant with vast empathic and telepathic abilities that were traumatically awakened during childhood when she witnessed her best friend's death. For years, Jean Grey was mentored by mutant specialist Professor Charles Xavier, a telepath himself. Eventually, she also developed telekinetic powers. When Xavier opened a school for mutants in order to prepare his students to carry on his dream of peaceful coexistence between mutants and humans, Jean Grey was enrolled as the last student of his first class. As Marvel Girl, she became one of the original X-Men, a group that fights for a world that hates and fears mutants.
Jean Grey is intimately associated with the Phoenix, an immensely powerful cosmic entity. After being corrupted by the Hellfire Club, Phoenix rose as the Dark Phoenix and caused immeasurable destruction. Jean Grey's conscience led the Phoenix to sacrifice herself to prevent further destruction. Jean Grey's connection to the Phoenix, a force of destruction and rebirth, inflicted a number of deaths, and resurrections. Upon her most recent return, Jean Grey permanently rejected the Phoenix and took the direction of a new X-Men team.
When all of mutantkind was united on the mutant-exclusive island nation of Krakoa by Charles Xavier's initiative, Jean Grey joined her former friends. On Krakoa, she was part of the governing body known as the Quiet Council, as well as part of recreating X-Force, the Krakoan black ops organization, in its intelligence sector. More recently, alongside her husband, Cyclops, she decided to reform the X-Men as a Krakoan super hero team who fights to protect mutantkind.
