Percy Jackson, banished to Tartarus for a crime he did not commit, is tainted and turned evil by an unknown, ancient evil, preceding the titans themselves. Percy is turned into this ancient being's champion, and is forced to fight against the place he once called home. Fallen Percy. Primordials involved. But what of camp halfblood, who think he is dead? T for language. Review!

When Percy and Annabeth fell into Tartarus, they had no clue the horrors in store for them. Three horrible weeks later, they have found the open Doors of Death, miraculously both alive. After the Seven save the world, Percy and Annabeth attempt to heal.

He's not a Demigod anymore- he left that aspect of his life behind a long time ago. Now he's an agent of SHIELD. With his past haunting him and the Avengers attracting trouble Percy Jackson is about to find out what it really means to be an Agent of SHIELD. Angst! Slight character bashing.
