The path the Jean Grey of this universe followed was seemingly the same as that of her Earth-616 counterpart, until the day when a Beast from an alternate future traveled to their universe in order to inform them that the future was in a bad state, and that only these X-Men could help fix it.
Jean and the rest of the team accompanied this Beast to the "future," where Cyclops had killed Charles Xavier, Jean was dead (and had the school named after her), and Beast was dying from his second mutation. Because Charles Xavier was not present, the mental blocks he placed on her telepathy were destroyed. That caused Jean to access her telepathy a year earlier than she was supposed to. After confronting and seeing into the mind of the "future Cyclops" Jean was repulsed and rejected her own Scott. Later, she used her telepathy to help "past Hank" save "future Hank" from death.
Under Kitty Pryde's leadership, the team decided to stay and resolve the problems of this time before returning to their own. Due to the present X-Men expressing doubt about Scott's leadership due to the actions of his future self, Jean was appointed leader of the displaced X-Men.
Following the battle with the future X-Men and future Brotherhood, which included a future version of young Jean who had defected to the Brotherhood, the displaced X-Men and Kitty relocated to join the future Cyclops due to Kitty's feelings that Logan's team had betrayed their founders.
Soon after their relocation, Jean Grey was abducted by the Shi'ar Empire to be put on trial for crimes perpetrated by the Phoenix. After her teammates and the Guardians of the Galaxy and the Starjammers team up on a rescue mission, they got into a battle with the Shi'ar Imperial Guard and Jean developed new powers combining her telepathy and telekinesis, fighting face-to-face with Gladiator and coming out on top. Afterwards, Jean pointed out that none of what had happened to her had happened before, so she should not be held responsible for a future she may no longer be a part of.
The time-displaced X-Men disbanded and went their separate ways in the wake of the M-Pox crisis, caused by the Terrigen Clouds roaming the Earth's atmosphere. The presenttime X-Men suffered a similar fate, though Storm eventually banded them together in order to face this new threat to her people. Jean was personally asked by Storm to join her team, and she accepted, even though she had spent the previous months building a normal life and going to college.
Once the M-Pox crisis was neutralized and the Terrigen Cloud was destroyed, Jean reunited with her time-displaced friends at Beast's request. Hank had found a way to go to the past, but he wanted to show them an unfortunate discovery. He had only managed to travel to the past within the timeline they were currently inhabiting and not their own, which led to them finding this timeline's young X-Men in the past they initially believed would be available for them to return. Now certain of their inability to return to their time, the young X-Men looked forward to the new future they could build, which was no longer tied to that of their present selves.
Warned that the Phoenix Force was coming to claim her as its host by the ghost of her older self, Jean refused to share her older self's fate and took steps to prepare for its arrival by consulting its prior hosts - Rachel Grey, Hope Summers, Magik, the Stepford Cuckoos and Emma Frost - as well as deific beings like Odinson, powerful psychics like Psylocke, and mages like Doctor Strange and Scarlet Witch. When the Phoenix Force manifested, Jean engaged the cosmic entity in battle and managed to wound it. Despite all of her preparations and Ghost Jean's assurance that the Phoenix Force wanted her alive, the cosmic entity instead immolated the younger Jean Grey, reducing her to a charred skeleton in order to resurrect the older Jean Grey as its one true host. Despite not being a Phoenix host, Jean found herself in the White Hot Room, where the Phoenix attempted to destroy her using manifestations of its past hosts. Jean realized she was
somehow in control of the White Hot Room and commanded the Phoenix to resurrect her, which it did so as to get rid of her. She then returned to Madripoor, where she was approached by her resurrected older counterpart.
