In DC's New 52, Yrra first joined the New Guardians, having perused the Star Sapphire ring of a fellow Corps member to Earth, where she found Kyle Rayner in possession of it.
After the mystery of that strange occurrence was solved, she's taken up a romantic relationship with John Stewart, helping him in his Green Lantern duties, acting as, essentially, his partner.
In addition to following her belief in love and in the mission of the Star Sapphire Corps, that love is the only thing that can save the universe and bring it peace, she also seems to be very much trying to make up for the things she's done in her past during her quest for vengeance.
Yrra Cynril is a native of the planet Xanshi, where she was a member of the ruling family. As the eldest daughter of a royal lineage, she was sent to Okaara to receive training and education in the ways of a warrior by Warlords of Okaara. Initially resistant to this life path that had been set out before, she tried to run away from Okaara more than once and had to stay an extra year as a result. Despite her reticence, she did have a natural gift for combat however. While on Okaara for that extra year though, her home world, Xanshi, was destroyed becasue of a mistake by Green Lantern John Stewart. Yrra was unaware who Stewart was at time, so she blamed the entire Green Lantern Corps for the loss of her world, her people, and her family. She dedicated herself to her training on Okaara as never before, until she had gained all the skills she could from her teachers. Following this, she adopted the name "Fatality" and set off on a bloody path of retribution against the Green Lantern Corps that would eventually lead her to Earth where she would find Kyle Rayner, who, at that time, was the last Green Lantern in existence.
After her campaign to rid the universe of Green Lanterns, she eventually discovered that there was only one Green Lantern left in the universe: Kyle Rayner. When she located him, she attempted to ambush him in his civilian life. However, she unaware that his power ring did not have the twenty-four hour time limit before needing to be recharged by a power battery. He was subsequently aided by John Stewart, who revealed that he was the one responsible for the destruction of her planet. However, before she had chance for retribution, she was attacked by an alien creature and was presumed dead when only her arm was found a midst the rubble.
Yrra had not died however, and when she returned it was discovered that her arm had been replaced by a weaponized synthetic one. She returned again to Earth and this time hunted Jade, who was a member of the Green Lantern Corps at the time. After their confrontation, she was once again presumed to be dead.
The Controllers offered Yrra a a chance to join their newest attempt at an answer to the Green Lantern Corps - she accepted, and, again, fought Kyle Rayner.
While Rome Burned
Yrra was given a yellow power ring by a mysterious benefactor, which she used to attack New York City, demanding to be given Green Lantern. Kayle Rayner showed up to answer her challenge, they battled briefly, but Yrra used her ring to destabilize a bridge over the water. She could have done much worse damage, but did not, so no one was killed. She used the distraction to go after John Stewart again. She threatened to harm his girlfriend, Merayn, so John would have to watch, before she would eventually kill him. Kyle showed up and confronted her, asking her how she could reconcile her actions with her warrior's code, attacking a helpless man in a wheelchair as she was. She told Kyle that John had the blood of two billion of her people on his hands, and that a debt like that went far beyond her code as a warrior. Kyle used the time while they were talking to launch a sneak attack against her, using a pinpoint beam, angled, and fired quickly, to hit her in her eye. He then knocked her out of John and Merayn's apartment with an energy blast and pinned her to the ground with an energy construct, a two pronged spear in this case. Yrra swore that she would kill him, John, and Merayn if he didn't kill her. She was crying, wailing really, and seemed to be hoping for death. Kyle didn't kill her, instead he asked Yrra to give him the yellow ring. She was doing so, when the ring exploded her arm and flew off, apparently at the behest of the one who'd given her the ring in the first place. She ended up in the hospital afterwards.
John Stewart began visiting her in the Slab, wanting to talk to her about Xanshi. She taunted his attempts at therapy with her and his current confinement to a wheelchair. She had an innate ability to see the weakness and frailties in things. She told John that what she saw when she looked at him was a man in perfect physical health, meaning he had no spinal damage keeping him in that wheelchair and that it was all in his head. She was later released from the Slab thanks to Major Force using his government contacts. He wanted her to kill Kyle Rayner and bring him the ring. After that, she could kill John Stewart and do whatever else she wanted. All he wanted was Kyle's ring. She was outfitted with all the weapons she desired and engaged Kyle in combat, injecting him with a neurotoxin she was certain would cripple his ability to use his ring. Kyle overcame the drug and took her down with a thrown jet.
Green Lantern Corps: Recharge
During the events of Green Lantern Corps: Recharge, while Kyle Rayner, and other members of the newly reassembled Green Lantern Corps, were busy dealing with an attack on the Corps by the Spider Guild, Yrra, teaming up with Bolphunga the Unrelenting, who has had a long-held grudge against Guy Gardner, attacked the Corps. Yrra engaged Kyle in yet another duel. She very nearly had him dead to rights this time, when Kilowng punched Bolphunga and knocked him into her from behind. The ship they were on was coming apart at the time, Kyle and the rest of the Corps with him used that opportunity to escape.
Secret Society of Super-Villains
Yrra joined Lex Luthor's latest incarnation of the Secret Society of Super-Villains, presumably in order to have another chance at gaining vengeance against Green Lantern John Stewart. She was first featured in that role in the 6-issue Villains United series, where she was one of the team of villains the Society sent to bring down the Secret Six. Later, in Justice League of America #13-15, she teamed up with Poison Ivy, Killer Frost, and Shadow-Thief to take on, and capture John, Hawkgirl, and Red Tornado. After the Justice League of America's eventual triumph over the Secret Society, Yrra was turned over, along with the other members of the Society, to Amanda Waller and Task Force X. From there, she was teleported to an alien world that was being used as a penal colony. Her story after that was picked up in the 7-issue Salvation Run series, though she only played a background role and wasn't featured as a main character.
Sinestro Corps War
After the events of Salvation Run, Yrra managed to avoid being taken to prison again and eventually returned to space. She returned to the Vega System, where she hooked up with other bounty hunters. When Sinestro established the Sinestro Corps, she was recruited and given a Yellow Power Ring. After the events of Sinestro Corps War, Yrra was among the female members of the Sinestro Corps, scattered across the universe, apprehended by the Star Sapphire Corps.
Joining the Star Sapphire Corps
Following the Sinestro Corps war, after being captured, Yrra was brought to Zamaron. There, as opposed to imprisoning her, like the Green Lanterns would have, the Star Sapphires sealed her inside a crystal that attempted to alter or heal her mind by fueling her with the violet light of love.
Once the process was completed, Fatality emerged from her crystal cocoon as a Star Sapphire, with her first thought being to locate John Stewart.
Yrra later located Stewart on Okaara, while the Green Lantern Corps were engaged in a battle with the Orange Lantern Corps.
Separating Stewart from the fight with her new found power, she explained to him that she had changed. The Star Sapphire Corps had made her realize how wrong her previous actions had been and they even allowed her to forgive herself for not being there for Xanshi's destruction.
Before leaving Stewart, she told him that next time he grieves among Xanshi's remains, he should forgive himself too.
With that business concluded, Yrra returned to Zamaron just in time to defend it against an attack from the Sinestro Corps, who had come to retrieve their captured female members. Even though she was originally one of them, she had already been converted by the Star Sapphire Corps, unlike many of the others.
The battle on Zamaron between Yrra's Star Sapphire Corps and Sinestro and his Corps was cut short, with the onset of Blackest Night. Yrra and the Zamarons fled Zamaron after the lovers who had powered their battery were converted into Black Lanterns.
Yrra ended up joining a coalition of lanterns from different corps, that included Kilowog and John Stewart of the Green Lantern Corps.
Yrra's dead home-world, Xanshi, was reanimated by a conglomeration of many Black Lantern rings and brought to Earth to attack Coast City, where the final battle in the Blackest Night was taking place.
Her new ad-hock team fought their way to the center of Xanshi to destroy those rings and stop the threat to Earth. Pieces of Xanshi rained down on Earth and her team and others constructed a latticework of energy constructs to protect Earth from the fallout.
The New 52: New Guardians
When the Star Sapphire from Sector 22 is murdered, Yrra is sent to confiscate her power ring. When she finally located the power ring, she found that it was in sector 2814 on planet Earth. Once there, she discovered that the power ring was in the possession of Kyle Rayner, and that he had possession of other Lanterns Corps power rings. To her surprise she found Saint Walker, Arkillo, Munk and Bleez there as well. After interrogating Kyle, the group headed to Oa and later to Okaara, in search of answers before being forced to confront Invictus. Yrra would continue working with the group for a short while until the events of Wrath of the First Lantern forced them to split, to help protect their fellow corps.
The New 52: Green Lantern Corps
Following her departure from the New Guardians, Yrra has been perusing her relationship with Green Lantern John Stewart, basically acting as his partner.
