<P> Strange psych occurrences around the world, which include a large bird flaring out from the sun and an explosion on the moon, raise red flags for the X-Men, who quickly launch an investigation of these events . After a string of bizarre encounters with familiar enemies, many of them considered deceased, the X-Men come to one conclusion: the Phoenix Force is back on Earth . The X-Men also discover that psychs are going missing or falling ill, which prompts the team to investigate the grave of Jean Grey . As they find the coffin of their long - dead teammate empty, they race to locate the Phoenix before it can find a suitable host . As it turns out, with the time - displaced teen Jean Grey out of the Phoenix Force's way, the cosmic entity has already resurrected the present adult Jean Grey . However, she doesn't recall her life as a mutant and an X-Man, and terrible visions from her previous life have left Jean unsure of the difference between reality and fiction . As she lays inside of what appears to be a Phoenix Egg, the X-Men theorize that the strange psych occurrences are subconscious cries for help made by Jean Grey and must try to stop the Phoenix from merging with their old friend . Old Man Logan is able to make Jean Grey remember her true life and she learns about the fate of her family and several of her friends, among them Cyclops . As Jean faces the Phoenix Force, she is finally able to convince the cosmic entity to stop bringing her back and let her go . Alive once again, Jean is reunited with her friends as the Phoenix Force journeys back to space . </P> <P> Restored to life, Jean gathers some of the greatest minds on Earth together so that she read their minds to plan her next move . Recognizing that there has been a sudden surge in anti-mutant sentiment, to the point where there are plans to abort pregnancies if the mutant gene is detected, Jean announces her plans to establish a more official mutant nation, making it clear that she will not establish a geographic location for said nation as past examples make it clear that doing so just makes mutants a target . To support her in this goal, she assembles a team including Nightcrawler, X-23 and Namor, but is unaware that her actions are being observed by Cassandra Nova . </P> <P> In All - New X-Men, present - day Beast goes to the past and brings a younger version of Jean to the present day along with the other original X-Men in hopes of helping the present - day Cyclops to see how far he's fallen . This version has experienced a surge in her abilities due to the trauma of being brought to the future . The time travel also caused her suppressed telepathic powers to awaken much earlier in her life than they were supposed to . She also has a habit of reading people's minds without their permission, to the great frustration of her team . During the Battle of the Atom crossover, a future version of this Jean Grey, who had never returned to the past and whose powers had grown beyond her control, would return to the present as Xorn, a member of the future Brotherhood of Mutants . Xorn perished during the battle, but in the process the X-Men also found out that there is something preventing the All - New X-Men from returning to the past . During this timeline, she reads the mind of current Beast, who regrets never admitting his feelings for her, so confronts younger Beast and gives him a kiss, which creates problems with the younger Cyclops . She and her team also leave the Jean Grey School for mutants and go to Cyclops's school, where she forms a reluctant friendship with Emma Frost as she trains her psychic abilities . </P> <P> Jean is later kidnapped by the Shi'ar and placed on trial for the destruction done by the Phoenix Force years earlier in a 2014 crossover story line Trial of Jean Grey . The All - New X-Men team up with the Guardians of the Galaxy to rescue Jean from the Shi'ar homeworld, but Jean would end up awakening a new power that she never had, in which she is able to absorb massive amounts of psionic energy from others and combine her telepathy and telekinesis, which she used to defeat the powerful Gladiator, leader of the Shi'ar . </P>
