(Percy Jackson and the Avengers) What if Percy wasn't only the son of Poseidon? What if, when he was still a baby, Loki made Percy his son as well? A lot of chaos that's for sure. When the Avengers find out about Percy, what will happen? Set during and after the Battle of Manhattan (Avengers) and will go along with the Percy Jackson books. Just add the Avengers. I do not own Percy Jackson or the Avengers or any familiar characters.
