Percy Jackson and Annabeth Chase have survived countless monsters, gods, Titans, and finally their most difficult opponent of all--high school, though not without their fair share of mishaps and unexplained absences. All they want to do now is enjoy their summer before tackling their next adventure; college. After a series of strange encounters, however, they realize that this summer is going to be just as eventful as the rest. Meanwhile, Earth's Mightiest Heroes are fractured. Tony Stark and Steve Rogers haven't spoken in months, and even with new members, the team is suffering. They know that something is coming, but the question is; will they reconcile in time to thwart it? With the appearance of old friends, new enemies, and peculiar allies, the Avengers are forced to accept that the world is even bigger than they thought. A/N: Important information such as the timeline and other details provided in the beginning author's note.

After the war with Gaea, Percy left CHB to escape the memories. But what when SHIELD wants him locked away? Percy has lost everything, and now he's also a wanted criminal. Will he escape a life in jail??? Amazing cover by: rAnDOm-caPitAls

Percy and Annabeth are finishing high school at Midtown High. Phil and his team are trying to find the terrorist, Perseus Jackson. What will Percy do when offered to save the world again, but this time, with the Avengers. A/N: This takes place after the Blood of Olympus, Season 2 of Agents of S.H.I.E.L.D., and Avengers Age of Ultron, so spoilers. Also, Simmons didn't disappear, and Bruce is still MIA. Finally, I don't own anyone, they belong to either Rick Riordan or Marvel

Percy had been kept behind enemy lines. Hydra lines. Hydra found Percy to be an adequate subject and started testing things in him. They wore him down and broke him. What happens when the new Percy meets the Avengers? (This starts a little before Age of Ultron and continues through that timeline). DISCLAIMER: This will be said now, and only now. I do not own any character of Percy Jackson nor the Avengers. Those rights go to Rick Riordan and Kevin Feige(?). BUT, like, half of the plot is mine. (Y'know. Otherwise how else did Percy get there?) Most impressive rank: #1 in the 'percy' tag

Nico just wanted a happy meal, that's all. But apparently looking at government agents (SHIELD/ Avengers) and running is suspicious. So is looking exactly like a dead person.

Sequel to Agent Jackson: Level 12

Percy Jackson is trying to be normal. He has tests to take, he has a girlfriend and friendships to keep up. He has a life, but of course the fates have other plans for him. Percy Jackson gets chased by some strange people in spandex, so what's he do? He ran, which seems to have been a mistake. Now the Avengers are looking for him and without knowing their intentions, Percy begins to question his choices. Then things just get worse from there!

It'd been about a year since Thor had left. The project to bring Thor back through a tesseract portal was moved to a SHIELD base, after Nico Di Angelo wrecked it to 'prevent the worst'. Jane Foster and Darcy Lewis were moved to another facility to work on another project, but Erik Selvig stayed. Nico, after a talk with Nick Fury about behavior was moved to a facility far away from the Tesseract. He had been put on the Avengers Initiative, and then hired as a SHIELD agent. He was at the top of their ranks in days. He went on extreme missions that were near impossible to complete as Shadow. Currently, he was getting Bruce Banner in order to track gamma radiation from the Tesseract since apparently, just like Nico warned, the Tesseract brought nothing good. Though, Nico had yet to be told exactly what the new threat was....

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

Nico di Angelo just wanted peace after the war. However, the Fates just had to mess that up and throw a prophecy at him. Now he has to join a team called the Avengers.

Monsters are rising again with two new leaders to take another try at destroying the world. All Characters and setting go to Rick Roridan and Marvel
