Jean Grey

Jean Grey was ten years old when her mutant power of telepathy first developed. Jean was out playing when her friend was struck by a car. Jean experienced the emotions of her friend as she died.

Professor X, perhaps the world's most powerful telepath, put in place psychic shields that prevented Jean from using her abilities until she could handle them. Jean also developed the power of telekinesis and became a student at Xavier Institute for Higher Learning for mutants and a founding member of his mutant team, the X-Men.

Jean developed a relationship with teammate, Scott Summers, the mutant known as Cyclops. Returning from a mission on a space station, the X-Men had to return in a space shuttle through a solar radiation storm. Jean was the only that could fly the ship back home by reading the pilot's mind and encasing herself in a telekinetic shield. Her shield wasn't enough and Jean was dying of intense radiation poisoning.

At this time, a cosmic entity known as the Phoenix Force offered to save Jean. It created a duplicate body with all of Jean's personality, assumed her place, and placed Jean in a recuperative cocoon at the bottom of the Jamaica Bay.

The Phoenix actually believed itself to be Jean. The power became too much for the human portion it assumed and became Dark Phoenix. Dark Phoenix destroyed countless star systems. Put on trial by the alien Shi'ar Empire, the X-Men fought for Jean's life. The human portion of Jean resurfaced in the Phoenix and committed suicide to prevent any injury to the X-Men as they fought for her.

Some time later, the real Jean was discovered in her cocoon and Jean returned to the X-Men. Scott and Jean were married. There was some strain placed on their marriage through their lives as X-Men.

On a later mission, Jean and teammate Wolverine were trapped on a space station that was sent hurtling towards the sun. Barely able to stay conscious, Wolverine took it upon himself to ease her suffering by "killing" Jean. Jean's "death" unleashed the Phoenix Consciousness that was inside her which then resurrected her. In the meantime her husband, Scott, was having a telepathic affair with teammate and former villain Emma Frost (The White Queen). They fell in love. Upon discovering their infidelity, Jean nearly destroyed Emma's mind through telepathic torture and Scott ran off after a fight with Jean.

Soon after, Jean was again killed by Xorn, who had been impersonating Magneto. Through a electromagnetic pulse, Jean experience the equivalence of 200 strokes at the same time. She told Scott to "live" and died soon after. The Phoenix Force then returned to Earth and found Jean dead. It resurrected her (once again). Jean merged with the Phoenix Force and left Earth in an attempt to fully heal itself.

The Phoenix came back in Jean's body and the X-Men again had to face her. They immediately began preparations to capture her in an egg. Wolverine attempted to kill her but only weakened her. After a final battle, Jean was shown via telepathy, from Emma Frost and the Stepford Cuckoos, all the people that love and care for her. She tearfully realized that through this powerful emotion, she could overcome the Phoenix's urges of destruction. She left.

Jean has not been heard from since. However a small part the phoenix force did return and take the Stepford Cuckoos as its host.then the force reveled that there where thousands of Stepford Cuckoos at a lab called the world. Then it destroyed the extra Cuckoos because they where created to kill all mutants. Then it reveled that the original Cuckoos and the extras where the children of Emma frost, the White Queen. This part of the force became trapped in the Cuckoos new organic diamond hearts so that it would cause no more harm.

Powers and Abilities

The Phoenix Force is a completely omnipotent entity and is described as one of the most powerful forces in the universe. It can wield its energy and fire it into an immensely powerful concussive force. It can travel in time and space by collapsing its powers from the inside, much like a black hole, and reforms itself in its destination. It can absorb many kinds of energy, from the life-force of an individual to an entire energy of a sun. The Phoenix Force has the power over life and death itself. Since it is the source of all psionic energy, it has vast telepathic and telekinetic powers and is always searching for a host that is strong enough to bear its power. When the Phoenix Force does enter a host, it amplifies the basic abilities that host innately have, manipulate matter in sub-atomic levels, and can teleport others from various corners of the universe via wormholes. When the Phoenix Force leaves its host, it leaves behind a small fraction of its power within the host. Should the Phoenix Force be harmed, or possibly killed, it becomes an egg of cosmic power and incubates in the White Hot Room until it hatches out completely healed.

Alternate Realities

Age of Apocalypse (Earth-295)

Ultimate Universe (Earth-1610)

Jean Grey was put into a mental institute because she believed that she was hearing voices and seeing visions of the Phoenix. After her released, she thought that it was a god-like entity that will destroy the world. The Hellfire Club decided to merge the Phoenix and Jean together as she can be used for the interest. They successfully merge them together, but the Phoenix destroyed the club.

Recently, Charles Xavier was contacted by Lilandra Neramani, the leader of the Church of Shi'ar Enlightenment. she believed that Jean is the reincarnation of the Phoenix and wanted permission to prove that she is. In the process of testing, Jean exhibit a different personality similar to the Dark Phoenix, but Charles managed to suppress it back in Jean's mind. After the testing, Charles and Lilandra were informed by her assistant, Gerald, that she is not the avatar. But it is later proven that she is the avatar but he chose to keep it under orders by his true superiors, the Hellfire Club.
