Percy has never been on any quests in all of the years that he has been at Camp Half-Blood, so what happens when World War Two breaks out?

What will happen when Percy and Annabeth becomes the heirs of Chaos? What happens when they meet the Avengers? What happens when Avengers try to capture them? Will they fail or will they succeed? What happens when an enemy rises and threatens both the sides? Read to know! The events of this story takes place after The Blood Of Olympus and starts in between Avengers: Infinity War.

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's mother Sally has a past that haunts her. She may have left her old life behind but that doesn't mean that it won't come searching. Sally was childhood friends with Natasha Romanoff who decides to pay Sally a visit successfully involving Percy in more than he signed up for (as usual). Takes place after The Blood of Olympus and before The Avengers. I don't own any of Rick Riordan's creations, nor any Marvel ones. I also don't own the image used for the cover.

After being betrayed by everyone he loves, Percy Jackson not only meets the avengers, but also discovers he has more than one dad.

Percy Jackson is a son of Loki and Sally's sister Sarah, Loki can't stay for obvious reasons and Sarah died in a car crash. Percy goes to live with his Aunt Sally who adopts him at age 4 along with her lover Poseidon also adopts him for he senses he is also a demigod and a possible chance for him to be the child of the prophecy anyways. Note: Age 8 Percy finds out he is a demigod and goes to Camp Half-Blood Age 12 defeats Kronos Age 13 defeats Gaea Ages 9 to current (13) finds out his magic powers and some say he should be child of Athena for he reads for a long time. I know the ages are all wrong but I like this Percy Jackson meeting the Avengers at a young age. Takes place during/after Avengers movie and Before/During/After Age of Ultron
