Jean Grey

Jean Grey is a mutant and one of the original members of the X-Men.

Inner Circle
With the Phoenix still inside of her, Jean underwent treatments by Moira McTaggart, who tried to get her to remember that she had taken the M'Kraan Crystal into the sun and asked her what happened to her inside the sun. Jean began to scream after McTaggart asked her why the Phoenix had not left her alone yet and was soon contacted by Charles, who told her that they were there for her before the Phoenix Force stated through her body that she was as well. Charles asked Phoenix why she remained in her body and stated that she did more harm than good by remaining in her before the Phoenix caused the treatment center to explode. After the explosion, Jean uttered to the non-present Scott to help her. Scott was at a club when he received her cry for help telepathically and returned to the Xavier Mansion after stopping Dazzler from being kidnapped by a few members of the Inner Circle. After Wolverine pointed her out to him, Scott came to Jean and hugged her.

After Scott asked her how she was, Jean told him that the therapy worked and that she was better before Charles ended their reunion by stating that the two could talk after she received some rest. While in the hospital, Charles asked Jean what the Phoenix wanted. Jean replied that the Phoenix hungered and prompted a reply from the Phoenix herself, who confirmed that it did indeed. The Phoenix started to make large bright lights come out of Jean's mouth and eyes, prompting Cyclops to tell Charles to help him before the latter told Jean to control her. After Charles left the room, Scott revealed that he would have to go back to the club he attended the previous night, to ensure that the Inner Circle did not return for Dazzler. With the Phoenix dominant, she told Scott that he could leave her for another woman and stressed that he might have to protect her from him. Scott told her that she did not mean that, prompting Jean to tell him that while she did not, the Phoenix did. Scott assured her that he would stay longer and would find a way to help her.

Later that night, Storm approached Scott as he slept. She told him that it was getting late and that he should go before assuring him that she would watch Jean. Scott thanked her and promised that he would come back. With Scott gone and Jean asleep, Inner Circle resident telepath Emma Frost entered her mind, with Jason Wyngarde using his powers of illusion to create a fantasy. In the fantasy, Jean awoke to nearly-drowning in a sea before being saved by Shaw. He took her back to his ship, where he laid her in bed as she told him that she was not in her proper world. Knowing that she was correct, Wyngarde told her that she needed her rest and shushed her as she tried to explain her position and told her that all was well. Wyngarde fabricated a lie, telling her that she had stowed away on his ship and was desperate to see America. Jean lamented to him that she recalled another life, calling it strange and filled with unusual people that were somehow her friends while obviously referring to the X-Men.

Jason assured her that it was all a dream and asked her if she remembered how frightened she was when he found her. She recalled that he had told her about how beautiful she looked and confirmed that she remembered. After Jason told her that he would always be there when he needed him, the two kissed, with Jean reminiscing about when she married Scott. After waking up, she screamed and was comforted by Storm, who asked her if anything had happened to her. Jean told her that she merely had a dream, before stating that it had felt so real and asking Storm if she could get her a glass of water. While Storm left, Jean flew out the window of her room and after landing, found herself in her Phoenix costume before telling it to stay back and making her way into the club Scott was in. While roaming, she questioned why she was even in there and was devastated by seeing him be kissed by Dazzler. After Jason arrived at the club, Jean walked up to him and morphed back into her clothes in the fantasy and kissed him.

She willingly went with him to his ride and soon arrived at the Inner Circle's base. She and Jason had a wedding ceremony, where she agreed to take him as her husband before Rogue arrived and told her to snap out of her delusion. The X-Men soon arrived after her and fought the Inner Circle for her. Despite their initial disadvantages, the X-Men began to dominate the group before Jean made her willingness to serve them known when she shot Storm in the back. After Storm questioned why she would go against her, the Phoenix confirmed that it was not Jean's doing and that it was only her body before stating that she was Phoenix as her eyes began to glow. With Wyngarde thanking her, the Phoenix went over to him and kissed him.

Independence
Following their kiss, Wyngarde redressed the Phoenix in Jean's body as a member of the Inner Circle and took her into the room. After he argued with some of his fellow members of the Inner Circle, Sebastian went up to her and gave her a kiss on the check while asking her if he should refer to her as Jean or Phoenix. Sebastian explained to Cyclops after he yelled out that the X-Men were allowed inside their building so that he could introduce them to the Inner Circle's newest member, as he threw his hand in Jean's direction. Sebastian told her that her power and beauty were all inspiring before asking her if she would freshen up outside as he discussed her with the other members of the Inner Circle, the whole group discussing how they would keep her under wraps and control her power. Jean was brought back in and made to eat with the rest of the Inner Circle. The group toasted in her honor, causing Jean to show visual appreciation before toasting as well.

Cyclops telepathically contacted her, which caused her to show a worried facial expression that Emma Frost quickly picked up on and learned that he had made contact with her, soon allowing Wyngarde back into her mind and starting a duel between him and Cyclops. Jean approached Cyclops during their duel, who told her that he had come to free her. However, Jean claimed that she had already been freed and that she had been set free from the constraints of sympathy and morality that bind ordinary human beings. She told him that the Phoenix Force inside of her hungered for more and that Jason Wyngarde had shown them the way before questioning gleefully if he could see it all around him. As Cyclops told her that Wyngarde was deceiving her, Jean began to laugh menacingly at him and remarked about the dark joy of destruction. Wyngarde striked Scott in the stomach with his sword, seemingly killing him.

After Sebastian questioned if Scott was still alive, Wyngarde confirmed he was not by stating that when the mind perished, there was nothing to control the body and stated that his wife Jean had taught him and demonstrated that as he put his hands around her. However, Cyclops was not deceased, explained by Emma Frost as having still been connected psychically to Jean Grey. After being ordered to finish him off, Jean made her way to him before being completely interrupted by Wolverine. Ordered to stop him, Jean attacked him and nearly knocked him out as he laid defeated. Jean made her way to him and planned to execute Wolverine, before recalling when she came to his aid while he tried training during his injuries from Sabretooth. Regaining her senses, Jean questioned what she had done and questioned what she had let the Phoenix do to Scott.

Wyngarde told her that he had a job for her, to terminate Sebastian Shaw. She began to laugh manically, stating that no one controlled the power of the Phoenix and blindsiding Cyclops after he told her to talk to him while under the impression that Jean had regained full control. The Phoenix stated that she tired of their squabbling and told them to amuse themselves as she departed...

Background
Jean Grey was voiced by Catherine Disher in all her speaking appearances. Her cameo in was unvoiced.

In adapting the Dark Phoenix Saga, the producers could not actually kill Jean. The comics did state that the one who died was merely a copy of the real Jean, to absolve her of Phoenix's crimes. The producers did not have her commit the same crimes so she would not have the same blood on her hands.

In the Comics
Phoenix actually did destroy a star and the Shi'ar patrol.

She did die by the Shi'ar. Later it was revealed that the Jean who died was a copy and the real one survived.

Cable is the son of Scott and Jean's clone. In the series he knows about Scott and Jean but no direct connection is made.
