For Quasar, see: Wendell Vaughn
Phyla-Vell was created when her brother Genis-Vell helped to destroy and then re-create the universe. The alternate universe that was created was one in which the genetic process that was used to create Genis was so successful that his mother chose to also create a daughter.
Phyla is the genetic (albeit cloned) offspring of Elysius of Titan and Captain Marvel of the Kree, just as her brother Genis-Vell was; as such, she is an Eternal/Kree hybrid. She was aged at an accelerated rate and trained by simulators on Titan in most things. She has been shown to have the tendency to come off as cocky and overconfident because of her extensive training.
She was first seen attempting to neutralize her brother when he had gone insane, in effect helping to partly restore his sanity. She then immediately attempted to lay claim to the mantle of Captain Marvel, to which her brother refused.
Also during this time she began a romantic relationship with Moondragon, who had recently been in a similar relationship with Marlo Jones , Rick Jones' temporarily estranged wife. Moondragon was greatly hurt by the dissolution of the relationship, but Phyla piqued Moondragon's interest. It was implied that the two took a vacation together. Sometime later she was seen at the trial of Starfox.
Later still, she was seen during the Annihilation crisis. She sought out Drax The Destroyer when Thanos had abducted his daughter, Moondragon, who Phyla had been seeing romantically. She then sided with Nova’s resistance movement and was instrumental in Annihilus’ defeat when the Quantum Bands chose her over Annihilus during his conflict with Nova, turning the tide of the conflict.
With Annihilus defeated and Phyla wearing both a pair of Nega-Bands and the Quantum-Bands, she seems to be deciding to follow in the footsteps of her predecessors, her father, Captain Mar-Vell; the previous bearer of the Quantum-Bands, Quasar. Even going so far as to start calling herself the new ‘Quasar’.
Recently, Phyla and Moondragon were seen protecting a monastery to Pama on the edge of the Kree Empire. In the aftermath of the Annihilation War the denizens of the universe attempt to rebuild from the devastation, the war has left most without food or shelter and has made many desperate. Phyla is forced to defend the monastery from such people and have formed a gang of sorts, but she shows mercy in offering them shelter and food. She hears a voice from the Quantum-bands and it tells her to seek out the one who can save the Kree Empire which is now under assault by the Phalanx
Recently, as Phyla-Vell has adapted to the power of the Bands, with the help of a Cotati priest discovered that Annihilus had indeed corrupted the Quantum-bands when he wielded them. Phyla was drawn into the bands themselves and found an area of inky darkness within them. Shortly thereafter, she learned that with the Phalanx having cut off the Kree empire from the rest of the universe, also have cut off the Quantum Bands from the Quantum Zone, leaving only the energy that happened to be within the Bands for Phyla to complete her quest to find the savior of the Kree people.This savior turned out to be Adam Warlock, and the voice guided her to him was the last surviving sentience of the Supreme Intelligence. She raced against the Super-Adaptoid, who had been turned into a Phalanx Select, to reach Warlock and battle him over Warlock's hibernation cocoon. Even with her power dwindling, she defeated the android. But Annihilus' evil almost consumed her afterwards. It was only the intervention of Wendell Vaughn's spirit purging the darkness from the Quantum Bands that saved her.
Phyla's work was far from over, because her next task was to get Adam Warlock to cooperate. He emerged from his cocoon too early. He was amnesiac and unstable, not particularly wanting to listen to her about the Phalanx. Even when the Phalanx attacked, he was unconvinced, but he did at least escape with Phyla and Moondragon to a refuge he could remember. This refuge was a hidden facility belonging to the High Evolutionary. Having her doubts that Warlock was much of a savior, Phyla tried to explain the situation to the High Evolutionary instead and get his help. He could engineer an army of enhanced Kree warriors to combat the Phalanx. There wasn't time to make plans, though. The Phalanx teleported into the facility along with their leader, Ultron. She could only watch as Ultron killed Moondragon in the first seconds of his arrival. The High Evolutionary chose to explode the star his facility hid within to destroy the invaders, and Warlock saved him and Phyla from the blast, heading to Hala where there was another lab. Phyla remained devastated by Moondragon's loss.
The High Evolutionary betrayed her on Hala, siding with the Phalanx and giving them Warlock. There was nothing Phyla could do at this point. Her Quantum Bands had been completely drained of their energy stores. She could not stop Ultron transferring himself into Warlock's body and taking it over. Then as the battle waged on elsewhere, Phyla found a mysterious new charge in her Quantum Bands. She joined the battle and found where Warlock's empty husk of a body after Ultron had been purged from it. It turned out that the energy she wielded was Adam Warlock's soul, and she put it back into his body. She was then able to draw energy from all the souls the Phalanx had killed to power their Spire, reforge her sword and strike the killing blow upon Ultron.
Guardians of the Galaxy
Peter Quill, the Star-Lord, put together a team of heroes in the aftermath of the Phalanx conquest, and Phyla was among those he recruited. What she did not realize was that he used Mantis to telepathically nudge her into joining. A bond formed between her and Adam Warlock from their shared experiences fighting the Phalanx, and she spent much time with him on Knowhere, the new base for the Guardians of the Galaxy. She also tried to bond with Drax the Destroyer, wanting a connection to Moondragon's father.
When what Star-Lord had done to get them all to join was revealed, Phyla was deeply offended as most of the others were. She left with Adam but would later be seen traveling with Drax in his search for Cammi. This search took a detour when instead of Cammi they received information that could lead them to Moondragon, bringing them to Mentor whom promptly murdered them!
Quasar No More
She found herself ion a borderland called Oblivion, where the Quantum bands fell of her wrists seeing as the bearer was now dead. Not long after she was faced by her own demons (Her father, brother, and Annihilus) but Drax soon send them packing. They however were joined by Maelstrom whom used Moondragon as bait to lure them for his master Oblivion with the intent of then using them to cross back over into reality. After his apparent defeat he agreed to lead them to her but he led them to the Dragon of the Moon where he said Moondragon was supposed to be within the dragon that was regaining its strength after Ultron dispatched it back to Oblivion. Maelstrom however regained the upper hand once the Quantum bands re-bonded with him and quickly encased Phyla and Drax with the intent of feeding them to the Dragon in exchange for the Dragon using its energy to release Maelstrom from Oblivion.
After Maelstrom dropped Phyla into the Dragon's mouth, who was rising. and after a short battle with the original Quasar, Phyla tore herself out of Dragon of the Moon, carrying Heather in her arm. With the Dragon dispatched and Maelstrom gone Quasar tried to return the bands to her but Phyla declined stating that she couldn't fill his shoes and that she had powers of her own. Together with Heather and Drax she returned to Mentor's place where Heather demands to know what the price that Phyla paid for her was after Mentor startled observation of Phyla's change.
Back on Oblivion, Maelstrom reveals that their plan succeeded Death now has a new avatar Martyr.
War Of Kings
She and Drax rejoin the rest of Guardians of the Galaxy back on Knowhere accompanied by Heather. where she shows a more pessimistic view on things as well as more confrontational which disquiets the rest of the group. Upon Warlock and Gamora's return they are informed of the Shi'ar/Kree war and the Guardians need to intervene for the sake of the Galaxy. She is then placed on Star-Lord's team to visit the Kree Empire.
During the visit Phyla once more demonstrates a more combative stance when she mouths of against both Peter and Medusa. Upon her quick frustration with Medusa she draws her sword which prompts the battle eager Gorgon to try and engage her but she quickly blasts him sending him flying back to crash into a pair of soldiers. Even when Crystal tries to intervene on behalf of the Guardians Phyla once again tiring of the lack of resolution to the surprise and strong disapproval of her fellow team members snatches Crystal with the intent of forcing the Inhuman's to listen. Peter realizing that they lost any chance of peaceful talks thanks to Phyla's actions apologizes to King Black Bolt and teleports his team back to Knowhere.
Where Phyla teleports in bringing Crystal as a hostage with them infuriating the already angry Star Lord even more. She argues that they now have a bargaining chip to force negotiations. Moondragon is clearly disappointed in her but as she tries to reason with her they are interrupted by both the Shi'Ar Imperial Guard and the Inhuman Elite led by Black Bolt himself. Crystal having enough of it quickly turns things around on Phyla freeing herself. Phyla is convinced that she did the right thing but they soon find themselves fighting Blackbolt himself who after grabbing Crystal pulls out with his Inhumans from Knowhere leaving the Guardians to the deal with the Shi'Ar alone.
The team find themselves scattered with Moondragon, Gamora and Phyla heading in a different direction they however soon are missing Moondragon while fighting the Shi'ar soldiers. They soon find Moondragon but she is clearly concerned for her lover. Then Knowhere awakens from his slumber with a message from the future, sent by Starlord. The message says that the fate of the universe depends on Adam Warlock.
But it is too late. The Inhumans detonate a device known as the Terrigen Bomb, which creates a massive, expanding rip in space-time known as the Fault. Adam Warlock uses his powers to stop the Faults expansion, but at a cost to himself. He overlaps the time line with an unused future: the future in which he becomes the Magus.
Phyla stabs and attempts to kill Warlock, which enrages Gamora who in turn kills Phyla. Thanks to the help of Kang the Conqueror, Starlord and some other Guardians are transported to before this event, where Starlord stays Phyla's hand. She had made a deal with the Dragon of the Moon to kill the Avatar of Life, which she believed to be Adam. This was the price of releasing Moondragon to her.
But the help from Kang was not enough, and Adam transformed into the Magus anyway. As the Magus, he killed Phyla, along with Gamora, Mantis, Cosmo and Major Victory. Using the Cosmic Cube which he received from Kang, Starlord is able to revert the Magus back into Warlock, but only temporarily. At Adam's request, Starlord shoots and kills him. Phyla watches the entire thing happen outside of her dead body along with the rest of her fallen comrades. The Magus has staged their deaths and takes them back to Sacrosanct.
With the power of the Church's belief fonts, Phyla and the others are made prisoners, tortured into worshiping the Magus. The Magus is particularly interested in the Avatar of Death being one of his followers. While unconscious, the others help formulate a plan with Phyla, who has the power to escape the Magus hold on them. Cosmo and Mantis assist and Phyla is able to send a message to Moondragon and break herself and the others free. As they begin to fight their way out, Phyla is approached by Maelstrom, who is not happy that she did not complete her deal with Oblivion. He tells her a cocoon abroad contains the Avatar of Life that she has sworn to kill and if she does her job she will be released from service. But it is a trap, for inside the cocoon is the new Avatar of Death, Thanos. The enraged Thanos kills Phyla in a single blast.
She has superhuman strength and durability that is the norm for both Titans and Kree. She can also act as an "energy sponge" absorbing energy blasts and redirecting them as energy blasts of her own. She has exhibited flight as well.
For a time she came into the possession of a pair of Kree Nega-Bands which were apparently her birthright. After the events of Annihilation, she laid claim to the Quantum Bands which seemed to absorb the Nega bands. She primarily used the Quantum-Bands to manifest a "Quantum-Sword". Recently Phyla lost the Quantum-Bands during a trip to the realm of Oblivion to rescue the soul of her love, Heather Douglas.
Having apparently made a deal for Heather's soul, Phyla-Vell seems to have accepted a position as Death's avatar and has a new set of powers which have yet to be explained, though she still seems to be able to manifest a sword, but this doesn't appear to be made of quantum energy.
