Later on down the line, Rachel went to space on a mission lead by Charles Xavier to track down Vulcan. During the mission, she met Korvus, who was sent to kill her, but instead the spark of Phoenix in his sword rekindled her own Phoenix-enhanced powers during UNCANNY X-MEN #478-486. Since then, she and Korvus have traveled the spaceways to continue using their pieces of the Phoenix Force for good.
The antagonistic young mutant telepath Quentin Quire was initially mentioned int he same breath as the Phoenix Force in the last arc of Grant Morrison's NEW X-MEN run. Shortly after, in X-MEN: PHOENIX ENDSONG, he was brought back to life by a piece of the Force and even became one with it for a short time.
In other tales, versions of Quire from the future were seen wielding the Phoenix Force with relative ease. Later, when the Shi'Ar weaponized the cosmic power in their war with the Asgardians, Quentin made a deal to take on a part of the Force and even became a Shi'Ar god for a brief time before returning to Earth and using up the rest of his Phoenix power to remove Jubilee's vampirism.
During AVENGERS VS. X-MEN, the two teams had very different ideas about what to do about the impending return of the Force. Cyclops wanted to use it to restart the sputtering mutant race while Captain America decided to end the threat. The Avengers' plan to kill the Phoenix Force ultimately failed, splintering it into five pieces that entered Cyclops, Namor, Colossus, Magik and Emma Frost.
