The ancient world was a harsh and unforgiving place. Alone and without family, a child has almost no hope of survival. But the life of a demigod is almost always full of surprises. Unlikely friends and dangerous enemies often change destinies. With a little luck and the grace of the gods, what could have been ordinary can quickly become extraordinary.

It is three months after Gaea's defeat and Camp Halfblood is hanging by a thread. Percy is a shadow of who he was; a war hardened warrior. He takes on quest after quest to distract him from his losses, but he is still broken, no matter how much he tries to stay strong for the Camp. During a sudden visit to his mom's house, he gets a glimpse of her past while being pulled into another war. His PTSD is at an all time high and he was finally starting to accept their deaths when he discovers the woman he calls mom has her own skeletons hiding in the closet. And they are only now beginning to crawl out from the cracks. Albus Dumbledore and the Order of the Phoenix are running out of options. Voldemort is getting stronger while their numbers are dwindling. In a desperate attempt to gain allies, he tracks down an old student of his. Sally Jackson, or, as she was known, Sally Potter. Joined by some of her old classmates and friends, he tries to persuade her to join their war effort. To their surprise and disappointment, she adamantly declines only for the reunion to be interrupted by her teenage son. One who possess magic, the one they never knew existed.

This was the book to make me stay. Percy's persona is wonderfully written, the grammar is perfect, and it is completely original. Well done and I can't wait to read the rest." ~Unrealqueen "DAM YOU ARE THE GODDESS OF WRITING" ~Labinzel "This is one of the best stories on Wattpad period. Not just in fanfiction or crossovers but out of all the books on Wattpad. This is THE BEST and my FAVORITE. You are such a good writer!!" ~fanficreader14 ~~~

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

Reborn in a new world after he is killed by Zeus here lies Percy Jackson, but this is not your simple world. This world is complete with its own Adventures, Dragons, Dungeons, and just about anything you can imagine.

It's been a while since the Giant War. Annabeth sealed the doors with her life, and promised Percy that she would wait for him in Elysium. Percy went into a rage, he destroyed nearly everything in his wake, and wielded the Master Bolt. The war was won, and Percy Jackson was again, offered a wish, he was too distraught to think straight, so his wish was put on hold. Sally and Paul tried to offer consolation, but he turned than away, and left them for good. He went missing after that, neither Poseidon, Hades, or Apollo knew where he was. Percy had given himself to the Central Intelligence Agency to maybe do something good for a change. He was too good at his work, and quickly flew up the ranks. Percy Jackson was dead inside, without Annabeth, he was only a shell of his past self. He could hear her voice sometimes, laughing, yelling, crying. He soon became one to follow orders. As the years went by, he gradually eased back into the world, and slowly returned to a somewhat normal state. Then he confirmed his existence to Thalia and Nico, who quickly told the Gods, but only that he was alive and well. Perseus Achilles Jackson, Level Twelve Classified spy, and assassin, is now wanted by SHIELD to be a part of Avengers Initiative. *Warning. Contains dark scenes. Read at your own discretion.

Percy Jackson had his future sort-out, a simple life that's all he ever wanted. However, life has never been simple for him. Read as.his life turns a dark turn. Torn between heartbreak and pain. How will he deal with a new threat arising? Why is the Creator interested in him? Percy/multi. Percy/Annabeth/Artemis/Piper, and maybe more?

Perseus Jackson is not the demigod son of Poseidon, he is the son of Poseidon with Hera much before the both of them were married to their respective spouses. He must live in exile due to Zeus paranoia, only for Artemis to know where he is. What will happen between the two gods?
