Percy is accused of the attempted murder of one major and one minor goddess and the fading of a minor goddess. He is sent to Tartarus but years later the gods realize their mistake and bring him back just in time for a war against a new villain. Only this time Percy isn't the same. Tartarus changed Percy and not in a good way.

(A/N: I do not own any of the pictures or characters used in this fanfic.) You all know Perseus Jackson, the great hero son of Poseidon. We know his girlfriend, Annabeth Chase, and their friends, the Seven demigods of the great prophecy. There is Nico DeAngelo, and Will Solace, and even more. They are the good guys, and Percy, well, he's been good from the very beginning. That's just the way he is, and always will be... Or do we thought... When an all new dark force rises, Percy is the first one to realize it. The thing, it talks to him, and tells him to do things, bad things, unspeakable things. Things that Percy wants to do. He wants to listen to the voice. Can Percy resist? Dose he even want to? Or is that just the strange thing, whispering thoughts in Percy's mind?

(DON'T READ THIS VERSION, I HAVE A COMPLETELY NEW VERSION THAT IS WRITTEN FAR BETTER ON MY PROFILE) Percy Jackson has had a hard life, and no one denies that. Everyone knows about the suffering he endured, his pain, his misery, his ups and downs all thorough his life. The legends about him, his 'king of sass' moods, his quests. They know everything about their hero. But Annabeth got a glimpse of something more. In Tartarus, Annabeth got a quick glimpse of something that terrified her. She, nor he, ever brought it up again, but it always lingered in the back of her mind. What had she seen down in Tartarus? Was it possible, the happy, preppy, sass king, had a dark side?

Percy Jackson is not a good person. At least, not anymore. Percy has been through a lot. Annabeth is dead and his few remaining friends are scattered across America. Percy's been loyal and heroic his whole life, he's always done what the gods asked. And they have only ever repaid him with pain and indifference. So now it's his turn. His longing for justice is growing and the more bitter he becomes, the more it sinks in that without Annabeth, he has nothing left to fight for. But then again, there's nothing holding him back. Revenge is something that has long been above Percy. But at the end of the day, at least it's something to fight for. The gods have forgotten that loyalty goes both ways. It's about time someone reminded them what happens when you lose the trust of a Demigod who rules on loyalty. ////Don't be afraid to spam comments or questions, I love attention teehee////

They're gone. The gods always known that the children of the Big Three were liabilities. They were dangerously powerful and extremely decisive. And now two of them have gone AWOL. Zeus is panicking, as is Poseidon. Hades isn't as concerned, since his son wasn't one of the disappeared demigods. But Nico does have to stop the other two, along with Thalia. The two no one ever thought would ever go bad. But they did. And now everyone has to suffer the consequences. Percy and Jason have gone dark. *****THERE ARE VERY GRAPHIC SCENES AND SEVERAL TRIGGERING TOPICS SUCH AS SUICIDE IN THIS FANFICTION!
