Kyla Frost

{| class="article-table"	Origin
While Emma Frost was laying in a comatose state, Dr. John Sublime harvested eggs from her to begin experimentation. The Weapon Plus program began the cloning to develop a powerful weapon capable of killing every mutant on Earth by combining their telepathic abilities. Dr. John Sublime had created one last subject, using Emma's body and harvested another egg, with Julian Keller's sperm. The project was designated, Weapon XV. The other girls being the XIV were incubated and artificially aged inside the subterranean level of The World as well as Weapon XV. Thousands of girls were cloned from the ovum, but while the others remained dormant, six girls were sent to infiltrate the Xavier Institute as student sisters to hone their talents for Sublime's purpose. Kyla hadn't known how she had been created but after seeing Emma for the first time it became obvious. After the Xavier Institute went public, the orphan quintuplet sisters Sophie, Phoebe, Mindee, Celeste, and Esme, were enrolled. Kyla was apart of the Five-And-One, but she was kept secret by Emma, to protect the origins of all the girls due to the fact that Kyla shared special DNA traits, unlike all the other Thousand-In-One. To protect their secret origins, the girls unconsciously placed mental blocks in the minds of the faculty, preventing them from investigating their background as well as cloaking Kyla to be another student. The girls quickly gained the moniker "The Stepford Cuckoos", though their chosen codename was the Six-In-One. Kyla was jealous of this. She felt her own presence being ignored, with Emma paying more attention to the other Cuckoos. Emma Frost assisted the girls when Esme and Kyla had a crush on a student who turned out to be Stuff, an advanced guard of the Shi'ar. This sparked Emma to take a special interest in the girls, and the Cuckoos becoming her protégés. As gifted telepaths, they were registered into Professor X's psychic course along with their rival, Quentin Quire with Kyla left to train apart from the Cuckoos. Quire developed a crush on Sophie, but the Cuckoos considered him to be odd and completely rejected him. Sparked by his uncontrolled powers and learning that he was adopted, and fueled by the use of the drug Kick, Kid Omega led a rebellion of students at the X-Mansion. To stop Kid Omega and his Omega Gang, Sophie and the other Cuckoos covertly snuck into Cerebra. Using Kick to amp up her powers, Sophie and her sisters were able to stop Quire. Unfortunately, Sophie died in the process. Unbeknownst to the others, Sophie was actually being influenced into these actions by Esme, who was also using Kick. With the death of Sophie, the Five-In-One became the Four-In-One and Kyla tried to take this opportunity to join the girls, but Emma denied her, being that she wasn't quite ready for Kyla to be seen yet. Kyla was angry with this, and she went to the Cuckoos. The girls were furious with Emma Frost, whom they blamed for Sophie's death, due to Kyla's influence. To exact their revenge, they informed Jean Grey of the psychic affair between Emma and Cyclops. Not long after Sophie's death, Esme attempted to murder Emma by shooting her with a diamond bullet. While Bishop and Sage investigated the murder, Esme fled the X-Mansion fearing that the truth would be revealed about her involvement in the deaths of Sophie and Emma. Fortunately, Emma was saved by the combined efforts of Beast and Jean Grey with the Phoenix Force. With Esme now gone, Kyla became apart of the Cuckoos. Esme returned, it was alongside her lover, Xorn, posing as Magneto and his Brotherhood of Mutants. Esme and Xorn had both become mentally unstable through excessive use of Kick. When Xorn's affection was withheld from her, Esme turned on him, and Xorn killed her by burying her metal earrings in her brain. With the departure of Esme, the Four-In-One remained as is until Kyla had departed her sisters, just up and disappearing. Kyla joined a new team called Unity X-Men, as well as keeping in contact with her sisters due to their shared hive mind. The Four-In-One became the Three-In-One.
Kyla had been iced out by her sisters due to her friendship with Maxille, she and Maxille became a pair, being seen everywhere. She learned he confronted her sisters about the issue and Maxille nearly killed the Cuckoos, upon draining their psychic energy, but she had stopped him. After this happened, the Cuckoos shunned Kyla, no longer considering her their sister. But this didn't last long, soon enough the Cuckoos came to forgive Kyla but Kyla still remained on her own, no longer wanting to be held in the shadows of the Cuckoos. After seeing how Kyla could stand on her own, Emma admitted to herself that she truly thought Kyla would be the last Cuckoo standing and that Kyla would have so much more potential if she weren't so stubborn.
