My Name is Omega, Not Percy Jackson
Percy Jackson ran away from his family and friends because they betrayed him. Zeus and Hades ask if he wants to be in Chaoses army as a commander. Percy accepts and becomes Omega (his code name.) Percy never wanted to go back to earth but when the gods and demigods need his help to defeat Kronos and Gaea he must become the hero he once was. Disclaimer: All the characters belong to Rick Riordan, only one character belongs to me, and that is the forgotten god, oh and Daniel. This is not a Pertemis story, but has a little Pertemis in it. Under revisions.
