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

Spoiler warning for Homecoming and (obviously) The Defenders. After Peter decides to stay a street level hero, a mysterious organization enters his life and makes his life as Spider-Man harder.... The Hand. Things get even weirder for Peter when he meets the likes of Matt Murdock, Jessica Jones, Luke Cage, and Danny Rand and gets involved in the war against the Hand. Now Spider-Man must join the Defenders and save New York from falling into the control of the Hand.

This is my first story, so please don't judge. Also, I own neither Percy Jackson nor the Avengers. Basically, this is a wrong number fanfic, but with Percy Jackson, not just spiderson and Irondad or something like that. Feel free to comment, but I don't want people to fight in the comments, so try to stay calm if you do write something there.

Like most brothers, Percy and Peter Parker have always had a complicated relationship. With Percy's secret life as a demigod and Peter parading as a superhero there are many secrets in the Parker household. A/N: This story will mostly be a bunch of snapshots of the life of Percy and Peter as they grow up and secrets become revealed. Disclaimer: I do not own any of the characters. Rick Riordon owns the Percy Jackson characters and Marvel owns the Avengers and their villains

What happens when Nico Di Angelo accidentally texts Tony Stark? ~~~ Be prepared for hilarious drama, very weird author's notes, and lots of fanart and memes. There are also a few random chapters at the end of this that are basically one-shots related to the story. ~~~ DISCLAIMER: I am not Rick Riordan nor Stan Lee, which means (unfortunately) I do not own Heroes of Olympus or the Avengers. ~~~ Btw, this has Solangelo in it, so if you don't ship it, don't read this. ~~~ Why did it take me thirty minutes to come up with that? ^ ~~~ (Completed May 17, 2020)
