Each of the big three has a warrior-- one son from each god of the big three. Each son helps control their domains, the sea, sky, and underworld. They fight whoever appears as a threat. Helping the innocent and punishing the guilty. Then one day the warriors meet because of a new threat-- Will they see each other as enemies or allies? (AN ORIGINAL STORY MADE UP BY ME! APOLLOTHEFIRST! At least I think...)

What if Perseus Jackson was raised on Olympus by the gods? What if he was the strongest demigod to ever live?

Percy is the son of Poseidon. Jason is the son of Zeus. Nico is the son of Hades. These are the legendary warriors of old. Born from the bloody battles of war, they have a bond stronger than any other. Separated they are powerful, but together they are unstoppable. These are the deadly and powerful demigod son's of the eldest son's of Kronos. They have fought in both mortal and immortal wars. The divine shiver at their names, monsters run at the sight of these three brothers, and their enemies die by the swiftness of their blades. Can these legendary warriors face down the endless hordes that have been called upon from Tartarus himself? Or will they fail to defeat the most powerful child of Chaos?

A new threat is rising, Tartarus. The sons of the Big Three are called to face this new foe. To do so they all have to claim their true power. Otherwise Tartarus and every monster in his pit will destroy everything. Percy Jackson: Son of Poseidon- He made it through high school. He and Annabeth are going to make a life in New Rome. But Percy's plans get cut short by a new danger. Jason Grace: Son of Jupiter- So far Jason has kept his promise. He's been building shrines and remembering the mistreated and forgotten Gods. But now he has to put his project on hold to protect what he loves. Nico di Angelo: Son of Hades- Nico has been playing nice. Living at Camp Half-Blood with Will has made him happy. Or as close to happy that he's ever been. But when a new threat rises, Nico won't let what he cares about get hurt.

All credit goes to PercyJacksontheChicken on fanfiction.net. here's the description By: PercyJacksontheChicken When things go downhill for our favorite hero, Percy Jackson, he leaves sight of the gods and demigods. Blessed by Chaos, he now patrols the Earth, protecting others, as well as running from a crazy hunter. But what happens when he is forced to return? Not your usual betrayed story.

The Phantom isn't like you or me. He isn't mortal...not anymore. And he can't be considered a mere demigod, either. He is something...else. Something greater...more powerful...something impossible. The Phantom lives in a rift in the Universe. He created it himself. If you've seen him, chances are you've been an inch from death. He isn't a hero...not anymore. He isn't a villain. He just...is. Not he is back to save them...even if he doesn't really want to. Can you guess who he is? I think the title rather gives it away... Yes. The Phantom's true name is Perseus Jackson. He hasn't been called that in a very long time...

This is off the top of my head, so....enjoy, my lovely readers! Disclaimer for whole story: Rick Riordan owns PJO/HOO. Inspired by @ZanktheGreat Hope you like, Zank!

Two hundred years pass by and now the gods are faced with another was, this one against the creator himself, Chaos. Chaos feels that the gods can no longer rule and threatens war. He has his most powerful beings his army come fight against the gods. So what has happened to Percy Jackson and who will win this war. Read and find out!

Percy Jackson is gone. Or rather, he was forgotten. It was like Hera's scheme all over again; but this time, he had no Annabeth to stay by his side, or Poseidon to call his father, or Camp Half-Blood to go home to. The world simply forgot about him. His powers had betrayed him, those who were once his comrades became his enemies, and his legacy was lost. So he decides to write a new one.
