(Percy Jackson Mortal AU)
Percy Jackson was sent to a lab when he was just six years old. Everything about him, from his DNA strands to his physical strength was peculiar and unnatural, so his mother sent him away, thinking it would best for his health. They promised to give him back. But they found his immune system and his DNA so incredible, they kept him as a lab rat and moved their lab to California from New York. The thing so incredible that the scientists and experimentalists loved most, was his DNA was alterable. They could give him a chemical and his body would turn it into a power that he absorbed. Over the course of twelve years in the lab, one last power may be the one to help him escape the torturous lab.
(Probably Pernico. Maybe Jercy. Perleo? I honestly have no clue.)
