Perseus Jackson is the son of Eros, the god of love, procreation, and sexual desire and Loki, the god of shape-shifting, mischief, fire, trickery, and ice. (You may be asking how two males can have a child, please read, and you will find the answer.) He is also the Fates' son and plaything. They screw with his life, A LOT. He goes to Camp Half-Blood, much to Loki's displeasure, because of Eros, but Loki puts a spell on Percy to make him seem as if he is a son of Poseidon. Both Percy Jackson series by Rick Riordan play out, and this takes place during the end of the final battle with Gaea (I change the end up a tiny bit).
You may have read fan fictions about Percy Jackson being a god, but this one trumps them all (but I may be a bit biased). Of course it could also just be really stupid. You pick ;)
OFFICIAL DISCLAIMER: I don't own any of the characters, but Rick Riordan, and some other authors do (I don't think I have to name them because you will probably already know them). I also made this mature, because there are a few things that kids might not want to read about.
