The mutation methods mastered by the Kymellian Clan were highly unusual, completely different from the Ghost Clan's physical enhancement, the Centaur Clan's shapeshifting camouflage, and the Rogue Clan's adaptability. Other than the Civilian Clans, the genetic mutations of the other four clans far exceeded every trait human genes could express. This was because all four clans had undergone mature modifications in Kree Empire war laboratories and had been deployed in actual warfare against the Skrulls. Each clan had been designed to meet different wartime needs, and their differing modification paths had granted these lab-created Mutants distinct abilities—the Kymellian Clan had been the result of targeted mutation experiments intended to counter Skrull sorcerers, with some reference taken from the mutation traits of psychic-adaptive genes within the Skrulls. It could be said that all four clans with especially pronounced Genetic Mutation traits had once fought side by side.
However, after victory in the Skrull War, the Kree Empire government had been unwilling to maintain the enormous expenses of war slaves and genetic engineering. Thus, the war slaves of the four clans, along with the high-potential Civilian Clans whose modifications had only been preliminarily completed at the time, had been completely abandoned. Yet during the war, in order to ensure that the war slaves could replenish their ranks smoothly, the Kree Empire's frontline war departments had also handed over the technology to those slaves. After the Inhumans who had been repatriated to Earth settled in Attilan, their wartime fortress, the four clans, including the Kymellian Clan, had gradually strengthened their particular talents through inbreeding and even more radical genetic engineering.
Their specially modified psychic genes had continued to grow stronger. Skull deformation and increased brain capacity caused by drinking medicinal nectar had forged an increasingly close connection between the Kymellian Clan and the
