After Gamora donned the identity of Requiem and set out to collect the Infinity Stones, Phyla-Vell and Heather travelled to the neighboring universe of Earth-616 to retrieve their universe's Reality Stone since each version of this artifact across the Multiverse had become displaced to an adjacent universe. They confronted Star-Lord and Collector, who handed the Reality Stone over to Phyla-Vell since it was useless in their 616 universe.
Heather and Phyla-Vell lost to their universe's Requiem, and since their universe was now doomed, Heather took control of their Requiem to make her use the Infinity Stones to shoot Heather and Phyla-Vell out of their Earth and into Earth-616 to escape.
After they helped prevent the destruction of Earth-616, Phyla-Vell and Heather left to explore the new universe they would inhabit from then on and they joined the Guardians of the Galaxy.
