Children of the Underworld

Percy Jackson, he is the first child to have ever been born as a mix between the Greek and Roman Pantheons. Much different than you think. He was born as a result of his father combining his two aspects together. As a child of both Hades and Pluto, he is immensely powerful, and will one day make a decision that decides Olympus' fate. AU Percy as a child of Hades and Pluto.
