Highest rank #298 in Fanfiction They could not believe that they were stalking a teenager! Them the Avengers were spying on some kid because he had a suspicious file! Granted they had sent others but the next time they were seen was when they were dumbed on the doorstep of the Stark tower. It also didn't help that they were all beaten to hell and back. That's the reason they were called in for this one and currently outside Goode High school waiting for Percy Jackson to walk out. (This will be going with the books and movies. The only difference will be with Thor. We wont be going with Magnus Chase version of him but... Oh just read it. AND NO THE SEVEN AREN'T DEAD! JFC!!)

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.

After the war with Kronos, the Olympians were weak. So they created guardians. The strongest of these guardians was a son of Poseidon named Perseus. He lived for hundreds of years. He fought in both the war against the Persians and the Trojan War, fighting along side the great Achilles himself. After serving his father for hundreds of years he disappears. At the final battle of the second Titan war, Perseus makes an entrance worthy of Zeus and defeats the Titan Lord. When he is reunited with his family, he brings terrible news of another war with Gaea and her giant children once again. Unfortunately or fortunately, the Fates are not in control of when he dies. That decision is up to the great Chaos himself. Cover by Xx_Anaklusmos_xX

Princess Annabeth Chase of Greece must work together whit some special allies to save Olympus and the world from the Titans. The Titans hunt the demigods to get one child from each of the big three gods. A child of Zeus, a child of Hades and a child of Poseidon. They need them to get the treasure of Olympus. The key to destroying Olympus. But it all can be stopped by one Captian of a certain ship.

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

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!!

The war with Gaea is over, but Annabeth, Jason and Piper are dead. Percy is struggling to get over Annabeth and just trying to live a normal life when he is recruited by the Avengers. *** "Why is his folder so classified, don't you trust us enough?" Romanoff asked, shooting me one of her famous glares. I just glared back and answered, "I don't have the clearance to access it." They all sat in a stunned silence for a few seconds before shouting at me. "You're the director of S.H.I.E.L.D, how don't you have access!" "Stupid mortals." "If he's so classified how can he be on our team?" "Shark Tank! That's BRILLIANT!" I raised my hand and waited for silence, one by one they all copied me until just Stark was talking, "Did you guys read the cannon bit yet!" *** Set after BoO and the first Avengers movie. Loki is an Avenger. Tartaurus and Kronos are NOT the bad guys (well they are but you know what I mean... I hope) ****** DISCLAIMER I do not own any of the characters, they belong to Marvel and Rick Riordan. * Cross posted on ff.net
