X-Men: Pheonix Endsong #1-5
The Phoenix force is resurrected, only to be shattered again by a Shi’ar crew. It heads to Earth, very weakened and in the form of a firefly, it arrives at the home of the X-Men, and flutters around Wolverine, the Stepford Cuckoos, and Beast, while discovering that Quentin Quire is still alive and held in a tank in Beast’s lab. The Phoenix finds Cyclops and the White Queen, and causes Scott to dream about he and Jean Grey, resulting in him losing control of his powers temporarily. After Cyclops talks to Beast, a very disgruntled White Queen reminds Scott that Jean Grey, his first love, is dead. The Phoenix finds the graveyard and calls to Jean Grey, who, even though she is not ready, climbs out of her coffin and back to Earth.
The Phoenix and Jean struggle, before the Phoenix once again takes up residence in Jean’s body. Wolverine discovers the resurrected Jean and tries to learn what she is doing alive. The Phoenix forces Jean to don the Dark Phoenix colors, before Logan gets ready to kill her again - except the Phoenix stops him, and with Jean struggling to take control, it flies away.
Cyclops and the White Queen try to resolve their relationship conflicts over Jean Grey, when Wolverine informs them that Jean is back. Several X-Men discuss their options on what to do regarding the return of the Phoenix who has resurrected Jean Grey. They mostly agree that Jean is fighting the Phoenix, who has again become Dark Phoenix. Cyclops gives everyone their orders and sets about his plan, having Beast make a containment egg to hold the Phoenix once they capture her. Everyone is shocked when Quentin Quire is resurrected and goes in search of his beloved Sophie, only to find that she has died. He brings her body to the surface and decides that he will see what the Phoenix can do for them. Storm and Nightcrawler deal with a hurricane that is moving in the wrong direction, before coming into contact with the Shi’ar crew that have been harassing the Phoenix. They confront the Shi’ar vessel which is set on destroying the Phoenix and the second Omega mutant, Quentin Quire, who is moving North. After much debate, the Phoenix and Wolverine are bombed with a Shi’ar weapon, before Storm convinces them to help her stop Quire, not kill him.
Meanwhile, Cyclops, the White Queen, Shadowcat, Archangel and Beast prepare for their battle with the Phoenix / Jean, who is currently antagonising Wolverine. Wolverine and the Phoenix survived the bomb from the Shi’ar, and Logan goes about killing the Phoenix over and over again.
Jean seems to take control, and plunges into the frozen waters beneath them. Cyclops and company arrive, and the Phoenix returns, and the X-Men realize that it was not Jean who returned for Cyclops, but the Phoenix!
The Phoenix Entity holds Cyclops in her grasp, using his optic blasts to power itself, while Wolverine, the White Queen, Beast, Shadowcat, Archangel try to defend Cyclops. The X-Men know that the Phoenix thinks it wants Cyclops for love, because Jean Grey used to want him too. Cyclops has Kitty ready to crush his heart. The Phoenix says things that Scott knows he wanted Jean to say, until Emma re-enters the fray, offering the Phoenix her help, as the Phoenix cannot get Cyclops on her own. Before Emma can let the Phoenix consume her, Kitty grabs her, reminding everyone that Emma was once one of their greatest enemies, until Wolverine talks Kitty out of it.
The Phoenix consumes Emma, and while it gets used to the new form, Cyclops grabs her and seals them both in the containment egg. Inside, Emma / the Phoenix bathes in Cyclops’ optic blasts, while Beast monitors the egg, assuring everyone that no cosmic energy is escaping. But after a while, Emma can no longer contain the Phoenix, she is not strong enough for it, and adding to complications is the arrival of Quentin Quire at the Phoenix’s location.
Wolverine engages Quentin Quire in battle while Beast and Shadowcat defend the egg housing the Phoenix, Cyclops and Emma, however Quire manages to crack it, at the same time as Emma gives in to the Phoenix’s power. The X-Men turn their attention to stopping the Phoenix, but Quire manages to intrigue her, and they protect themselves from the others. The Shi’ar learn that Quire has claimed the Phoenix and begin the Endsong as they prepare for an Event Horizon, to destroy both the Phoenix and Quire, which Storm does not object to. Storm and Nightcrawler leave the Shi’ar to be with their friends, and watch as the Phoenix resurrects Sophie, who learns that Quentin expects her to be his girlfriend. Sophie is disgusted and kills herself, causing her sisters who are watching telepathically to jibe Quire, who goes insane. The Phoenix proceeds to leave in Emma’s body, until Storm stops her temporarily. Cyclops and Wolverine agree that they need Jean’s help, and as Scott blasts the ice where Jean is frozen, she emerges, firstly freeing Emma from the Phoenix’s hold, before she once again bonds with the Phoenix, to her friends’ protests. Cyclops informs a cosmic Jean that he knows why she came back, and with the help of the Stepford Cuckoos Emma uses her powers to telepathically “bring” the other X-Men to Jean, including Polaris, Rachel and Xavier. Various images of Jean’s time with her friends are seen, before Jean creates a new white and gold outfit for herself, just as the Shi’ar launch their Event Horizon, killing everyone. Cyclops finds himself elsewhere with Jean, and Cyclops fills Jean with assurance of who she is, and optic power. The X-Men wake, knowing that Jean saved them, and they saved her. Quentin dissipates and returns to his tank at the Institute, while later, a firefly lands at the window of the Stepford Cuckoos. One of the Cuckoos wakes up and asks the firefly what took it so long.
