Percy handed himself to the CIA after Annabeth died. He then cut all ties with the godly side of his family and handed himself to the CIA. Now, he is seventeen, and wanted by the Avengers Initiative. Was written before HoH, BoO, and Age of Ultron. EXTREME OOC'NESS. Sequel is up! I was much younger when I wrote this; I won't be editing it, so don't bother asking.

Adopted from Blueh. Used to be called The New Avenger. Percy knew that he had bad luck, as it always was for a demigod, but he never thought about how his life would change after a group of mortals witnessed him face off a hellhound. He didn't even think that they might be the head of a secret agency, or that they would want him to join a group called the Avengers...
