Percy Jackson saved the world. But the price was much steeper than he was willing to pay. To separate his life from the bitter memories of his past, Percy is sent to London to live with a distant cousin in hopes of a nice easy mortal life. He should have known the Fates weren't done with him yet.

She first saw him when she was 22 years old, and injured on a mission. He was 10 years old, and visiting an aquarium. Percy Jackson looked into Natasha Romanoff's weary but determined eyes, and decided to help her. And so, he pulled a lever, spilling his class and her enemies into a tank. That was not the last she saw of him. By the time several years pass, the two green-eyed siblings by bond will be known as heroes, albeit of different worlds. Perhaps they don't know everything about each other. But they do know that they will always have each other's backs. He helps her out when her missions don't go the way they planned, which doesn't happen too often. She teaches him how to be a good spy, although that isn't the intention when they start the lessons. And they become very close, just as close as true siblings, in fact. So when Natasha finds herself in a complicated position during the Avengers' Civil War, Percy decides to interfere. And the Avengers are extremely surprised when they meet Natasha's younger brother. Plans are made and set in motion, alliances are completely misconstrued, friendships are tested and broken, and the two siblings find themselves on their own side against the world. However, there's something bigger in the works for the Avengers, and they'll need all the help they can get to face it. Including the two green-eyed siblings in everything but blood. This is largely Marvel canon compliant up until Captain America: Civil War, with Percy's interaction with Natasha being a background to the PJO books. Cover by @cajoling - she's awesome, honestly I'd check out her work as well lol

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. [Disclaimer: I do not own any characters mentioned in this fanfiction. All rights go to Rick Riordan] ***on hold***

Six year old Percy Jackson lives with his smelly step father, Gabe. After watching his mother die right in front of his eyes, Percy becomes a selective mute. However, that doesn't mean he's useless. The kid has something hiding behind the sea colored orbs. It only took a cup of hot coffee spilling on his expensive suit for Tony to meet the boy. Never in his life did he think he would pull over and help a boy out of the rain who couldn't even speak his name. Yet, something drew him in... and he let it.

In a world where the wars are over, the hero has disappeared. He was turned immortal by a gift he never wanted. He vanished. But are the wars truly over? Will he return? Can he be found? Where did he go? Disclaimer for entire story: Rick Riordan owns Percy Jackson and the Olympians and Heroes of Olympus, I do not.

Percy Jackson has always been different. Even by demigod standards. He had normal demigod problems...dyslexia, ADHD, and monsters. He had normal problems. Bad grades, getting into trouble at school, that kind of stuff. But he was also the son of Poseidon, the subject of two Great Prophecies, the Hero and Savior of Olympus, one of the only living beings...gods included, to survive Tartarus, one of the only demigods to bathe in the Styx, and one of the only beings that ever held the sky. All that makes him different. But now, he was about to delve further into abnormality, when he finds out he has another evil grandfather. This time it isn't an evil, immortal, all powerful Titan Lord that likes eating his kids...just a powerful, evil noseless creep with a freakish, yet hilarious name that somehow makes people flinch. And now, Perseus Jackson, the son of Poseidon, is about to go on his strangest adventure yet...going to Hogwarts School of Magic. Yet another tragically hilarious name. (Look, I know there are a lot of these and it's pretty classic, cliche, and slightly overused, but I promise you readers that this story does not fit into that mold. Give it a shot, and see how it goes. But if anyone steals my plot...I'll feed you to my pet Hellhound :). )

As the final battle was drawing to a close, Gaea would not go down without taking the one person who gave everyone hope down with her. Percy Jackson soon found himself in a new world of magic, dragons, elves, and dwarves. An unexpected event put a giant target on his back only within a day of this new adventure and now Percy has to figure out what he wants to do fast. How will Percy cope with this new world and how big of a factor will Percy play in the ongoing war?

Summary: Perseus Jackson was betrayed by the people he called his family. Cheated by his girlfriend, Annabeth Chase, dis-owned by his father, forgotten and hated by his friend/family, and replace by his half-brother, Austin Reed, he left the place he called home. His mother died at the age of 6, he had no one. Until a person, powerful, older than the Olympians combine, helped Percy get back on his feet, a whole new fresh start, and hope. He left New York, and went to live with his Aunt Mellisa, and cousin Scott ( related by Sally ) who he hasn't seen since the death of his mother, to Beacon Hills, California. Living like a normal teen, life couldn't get any better. But the fates have other plans for him. Percy will soon figure out the secrets of Beacon Hills, and will soon go back to his old life, sooner than he thought. And all the problems seem to be at the center of his cousin Scott, Stiles, and him. ( Start of Teen Wolf and End of PJO and HoO )

This is something I have been experimenting with for a very long time now, so I hope you all enjoy it. Disclaimer: I do not own PJO/HOO, Rick Riordan does. Clue: About the Hunt and Apollo. But let's not forget the man himself, Perseus Jackson.

What happens to Percy Jackson when the Manticore comes back and chases him into a new world? Disclaimer: Rick Riordan owns PJO/HOO.
