Percy was found as a baby due to his sister hiding him from certain death. The god that found him was neither Greek nor Roman but something much more powerful. Upon returning him to one of the most powerful (I think the most powerful deity) beings, he was adopted by him and his family. Now called Parsī, he will be the strongest hero in history. (COMPLETE AND UTTER HAREM) Enjoy :)

Arceus had a severe vision of a terrible evil returning, however, Ash Ketchum the Chosen One perished due to an unforeseen disease that took his life. The only thing left now is to have Dialga and Palkia create a new timeline which will rewrite history as they know it. But Ash can't do this alone, another champion must be crowned. A Champion of Aura.
