Doctor Strange was always fond of having some aces up his sleeve, and keeping tabs on Percy Jackson felt like the perfect occasion for him to do so. Little did he know that the teenage demigod would come in handy when it came to a certain war. All Percy wanted to do was graduate high school, even if that meant having a kid named Peter Parker tutor him. [I don't own Marvel or PJO/HoO, all credit goes to their creators] (do I even need to add this? Whatever, better to be safe than sorry.)

The World was at risk once more and he was called to fight for it again. Percy Jackson has outlived two wars; What can another one do to him. PERCY JACKSON AND AVENGERS COSSOVER age au (pjo) avengers assemble (set)

COMPLETED WE PROTECT After the war with Tartarus, things start winding down. Camp Jupiter heads for California, Magnus and his friends go back to Boston, and Carter, Sadie, Walt, and Zia head back to Brooklyn. But the Avengers stay. Because Percy needs them now more then ever. After getting run through with Tartarus's Under-worldly sword, Percy needs all the help he can get. The Grove of Dodona gave some helpful pointers such as, "Don't be afraid of your fate." He's trying, but will he ever get better? DISCLAIMER: I DO NOT OWN PERCY JACKSON OR MOST CHARACTERS. THEY BELONG TO RICK RIORDAN. AVENGERS BELONG TO MARVEL.

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.

[Poki] Get gay or get out. Percy Jackson is alone, whether they left on their own or he pushed them away. When he doesn't know who to turn to, he returns home to his uncle, Tony Stark in hopes he and his friends can help him control the darkness inside him. Cover by: @donutfindme

(Percy Jackson/Avengers Crossover) (Percy/Jason) Highest rankings: #1 in 'jercy' #27 in 'crossovers' #16 in 'percyjackson' Percy Jackson is a mystery - to Spider-man, to the Avengers, to SHIELD. But when they meet to battle a common enemy, they find they have more in common with the warrior than thought. And Fury seems to know him better than he's letting on. •Crossposted on AO3•

Captain America, the super soldier, war hero, the first avenger. Bucky Barnes, Steve's best friend. Until he died that is. But we all know now that he never really died. He was taken by Hydra and experimented on. Turned into the Winter Soldier. But during the time the Avengers were breaking apart, fighting against each other, they found out that there were more Winter soldiers. Men and women turned into super soldiers, people even stronger than Bucky, the first Winter Soldier, with power that could rival even Captain America himself. But when they later raided the base, they found every one of them dead. What they didn't know was that years ago, one of them had escaped. One Winter Soldier still alive. One Winter Soldier that could rival Captain America. One Winter Soldier with the power of the gods in his hands. And this Winter Soldier's name is Percy Jackson.

Steve stared wide-eyed at the mound of ice the SHIELD Ops team had fished out of the arctic five miles north of where he was found. The thing had been defrosting for close to two hours now, and he could just make out bits and pieces of the person underneath. Not that he would ever need to see the body to know what Percy Jackson, codename Western Flame, codename Submariner, codename First Captain America, looked like. He had grown up and fought with him and Buck after all. We're onto the Winter Soldier 'Era' now! Operation save Neeks and Bucky is a go!
