People who are born with two souls in their body are rare. But since when did Harry and Percy obey the rules? Follow them as they try to survive after their brother was mistaken for being the Boy-Who-Lived. AU. Wrong BWL

This is a story I also have on Quotev under the same name and username, and I was going to post it on here at some point so I decided on a whim to do it now instead of later. Summary: What would happen if Percy Jackson and Harry Potter were twins?? What would happen if on the night Voldemort attacked the Potters and became a wraith, Dumbledore separated the twins, giving Harry to the Dursleys while shipping Percy off to a supposed squib by the name of Sally Jackson?? What would happen if they met up at Hogwarts, knowing that the other existed and had already formed a deep bond?? Well, let's just say that Dumbledore isn't getting the brash, ignorant Boy-Who-Lived Harry was in canon, because now, Percy comes in and does what he does best; he messes with Fate, kicks butt, and pulls off death-defying moves to protect his friends and family!!

What if Sally Jackson had a half-brother? What if he was a wizard? And what happens when Percy decides that he needs to help his uncle out? Percy travels across the seas, and into the shadows in a personal quest to help his uncle survive his role as double agent. And all the while, Percy must do his best to hide his true identity from the leader of the side his Uncle is spying on, Lord Voldemort.

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

You remember the war with Gaea right? Leo dies, is brought back to life etcetera, etcetera. What if the war ended with more casualties? What if the fates themselves gave Percy a solo quest? What if it was during World War II? Worry not, this IS a Percy Jackson/Captain America crossover. DISCLAIMER: I DO NOT OWN EITHER OF THE SUBJECTS OF THIS CROSSOVER BUT I DO OWN THE PLOT! DO NOT STEAL IT, I WILL REPORT ANY COPYCATS TO WATTPAD FOR PLAGIARISM
