In which the Avengers know that they can't defeat Thanos alone so they call a powerful ally to be on their side. Disclaimer: violence,mild swearing I DON'T OWN MARVEL AND PERCY JACKSON! THEY BELONG TO STAN LEE AND RICK RIORDAN! THANK YOU!

"Then you have incurred the event horizon upon yourselves. I am the bane of the Protogenoi. Now, prepare to meet your doom." A year after the Second Giant War, Percy Jackson is living a life of peace. However, when a bitter son of Nemesis enters camp, his life turns upside down. Will he break? "For I created the cosmos, and now I must stand against those who wish to destroy it."

Eons ago before the present time, there was a prophecy: announcing the deaths of the Olympians at the hand of a God Killer. Someone was said to stop this God Killer, a powerful half-blood hero: a Nephilim child. But, what if he didn't want to save the gods. What if he knew how they acted like and what if he wanted to kill them, believing them to be threats to humanity? OC Centered

Clint Barton didn't expect visitors in Homestead. Especially teenagers stealing from him in the middle of the night. But when Clint confronts him and realizes he's not alone... well, what's he's supposed to do? The Avengers have everything, it seems, but a family man. Featuring fanboy Thor, Steve's overprotective nature, and twice the Jackson as you'd expect. (Percabeth later on.)

What happens when Nico Di Angelo accidentally texts Tony Stark? An Avengers/Heroes of Olympus crossover.

The avengers make a grave mistake

The infinity stones are surfacing, what will Zeus do, will he just ignore them or will he actually give heed to them, also what will happen to Apollo, What is percy doing?, All questions will be answered. Please read and tell me if I should make more chapters or not.

When Directory Fury sends the Avengers to bring Percy Jackson in for questioning what will he do? Will he join the team of misfits protecting the world or will he refuse to get attached to anyone else. Crossposted on Wattpad. Set after the war with Gaea. Will also have some slight crossover with DC Arrow. Idea from BlahBlahBlah144000 on Wattpad.

Steve Rodgers is getting used to the modern world, what happens when he crosses paths with someone from his past? What is she hiding? How is she connected to Peggy? Will demigods be able to work alongside the Avengers? This is the story of Aria hunter of Artemis and how she was destined to meet Captain America.

Two orphaned demigods. One uncle stark, who happens to be iron man. A family of super heroes. mutants, gods, cosmic gems, prophecies, titans, primordials, giants, and the fate of the multiverse. all on the shoulders of one boy, who is destined for great things.

Percy & Jason find themselves in the custody of the Avengers. While attempting to keep their world a secret and prove they are not a threat to mortals, they try to explain themselves without actually explaining anything. The Avengers get worried for these teens, thinking that there could be an organization worse than HYDRA turning kids into soldiers, which leads to more problems

Percy just wanted a normal day. But when the Avengers kidnap him and his girlfriend, he finds that hiding the mythological world from the mortals is harder than he thought. Join Percy as he learns about the superhero team's world while hiding his own. (I updated it to T because stabbing)

A third Great Prophecy. A war for the universe itself. This challenge is bigger than Percy and the demigods of New Rome and Camp Half-Blood can face alone. They must combine their forces with the greatest of Mortal Hero's and Percy must lead the forces of Olympus while at the same time keeping the mortals from discovering the gods. But the Mist is failing. Rating subject to change.

He lead as normal a life as he could, from Camp and those extracurricular activities. At least his sister and her husband were there sometimes. More than could be said for his mother. Maybe, once Tony Stark found him and brought him to Germany, it would all be a mess. But at least he could have some protection? (no bad language ever, rated because I'm paranoid) UPDATES THURSDAYS

"Wait, wait hold up. Agent Jackson-Fury?" Percy turned to face Tony "What is it Mr. Stark? Is it that shocking that my dad has a son?" At Tony, Steve, and Bruce's faces, Nick Fury snorted. "I think you just broke the Avengers, son" "Didn't think that this prank would have happened so well. Thanks for the help dad" Cross-posted on Wattpad and Archive Of Our Own(AO3) same username

Percy Jackson has finally escaped his life as the assassin known as the Shark. But things are not what they seem. A new threat is rising against Percy's new family. A certain Norse god with a grudge against his own family who wants to conquer the Earth. Will Percy be able to stop him? Or will he fall to the manipulations of Loki? (Revised "It's Time to Fight")

When Percy goes into Police custody, SHIELD does a background sweep on him. Realizing that he could be a dangerous terrorist, Fury has two shield agents bring him in. When Fury can't get anything out of him, he is given to Stark and the rest of the Avengers to keep an eye on him. Their task: Find out who this kid is.

For once, Percy's live isn't a Greek tragedy because of his godly relatives. No, this time it was aliens. In a world where superheroes and demigods coexist, the gods are not as all-knowing as they might think, and demigods and mortals alike must rise to the challenges of a new, more dangerous world. Part 1: "Of Gods and Men" series

Calla isn't seen. Ok, so she is seen... a lot. It's not her fault that Zeus struck her out of the sky, or that Captain America was once her best friend, or that she may or may not have hated George washington... whatever. This isn't that story. It is the story of what happened when she became an avenger. maybe OC/Steve Rogers(not likely)

Percy Jackson and Spider-Man meet accidentally. Peter Parker meets Percy Jackson on purpose. One way or another Percy Jackson is a hero to many and an enemy to even more. But with a control of powers that the gods haven't seen in a millennia, Percy Jackson is determine to survive, and keep those along side him alive as well.

SHIELD has many secrets, but this one secret is bigger than the most. The hushed voices whispered through the night called him 'Noir'. The tainted hero, the fallen prince. Unpredictable, unconquerable. "He's one with the sea. You can't restrain him, all you can do is to go with the flow" /Pairings undecided ATM/

It had been fifty-two years since the oath had been completed. A god mourns. Nick Fury takes notice of three teenagers who aren't aging. Little does he know, they aren't exactly normal.

As a result of a desperate attempt to save his life, Percy ends up in a new and unfamiliar world. Tasked with finding a way back, he realizes that it would be much more difficult than he thought when the world he finds himself in needs saving.

When the Avengers find 4 demigods and 1 god knocked out on the beach. They take them to stark tower. The Avengers noticed something is weird with the visitors. Will they be able to hide the secret from Shield? (Discontinued)

The Giant War is over. All of the Seven except Percy were killed. Now Percy just wants to relax but when he goes back his family is dead too. Also the Avengers are on the hunt for him. Surprising new revelations are in store for everybody be it demigod or mortal. Once again a new threat is rising and a new prophecy has been made. Will Percy be able to save himself and the world?
