Percy Jackson knew his 'aunt' since he was a infant. She was weird and her 'boyfriend' was also weird but that was the fun part. The only downside was when his mother died he was taken into Natasha's custody by her own free will. How will the Avengers handle the spies going soft over a kid. Percy will be smart Percy will be OCish Clintasha pairing Complete

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

The gods will rue the day they let Jackson, that rogue son of Sally Jackson and Poseidon, in on his heritage. And Jackson, well, he's ready to turn this world of Greek Mythology upside down. With his new friends, he might do just that. Besides, it's boring enough already. Time to make heads roll. Badass!Punk!Confident!Percy, AU

Six years since he left. He disappeared from the demigods, the gods know where he is but don't tell their children. He moved on after his love died. Only his cousins are allowed to contact him. This is Percy Jackson life, his code name is Riptide, and he is an agent of S.H.I.E.L.D...that meets the Avengers too. Includes Agents of SHIELD later on in Season 1 DISCONTINUED

Percy Jackson was Nine years old when his life changed. His mother died and he expected to be thrown into the system, only he was thrusted toward an uncle he never knew. That said uncle and his practically brother always disappeared when night came. Ten years old Percy found out where they went, what they did. He didn't want to be a superhero like his cousin, instead he was the mechanic behind the operations. But even then, Bruce wasn't always there for him when he sometimes wanted him to be, sure when he might've been sick or needed some boring school help he was but when it came down to it, Percy sometimes wished Bruce was never Batman. It was also weird relationship especially when Percy befriended Crazy, Not-So-Crazy person names Joker. It wasn't until he was eleven and a half is when he met someone who understood him more than the Wayne family, Luke Castellan a run away with no one but a schizophrenic mother, and he helped Percy. Started to treat him not like some rich dude's nephew, not some hot-shots younger brother/cousin, just...Percy Jackson the kid who lost his mother and never truly grieved. Notes: Darkish? Abandoned!Percy No Greek Mythology

Percy Jackson's first trip to America was one to be remembered, His father the great and powerful dark lord had to go on a negotiation trip to New York city and had taken him along. But Percy knew it was more then that. The way his father keeps stealing glances at him, like he had figured out a big secret and didn't know what to make of it. And something felt... different, the magic in the area felt so intense, the air practically crackled with power. Well.. that and the odd lightning strikes and storms. And he was sure someone was stalking him. #SEQUEL TO PERCY JACKSON, SON OF VOLDEMORT#

Perseus Jackson was left in an orphanage in London when he was just one years old until a man with cold red eyes and a snake as a familiar came and took him away. What will happen to the world's most loyal hero? will he create his own path? Or will he rule the wizarding world as the heir of lord Voldemort. #PLEASE BE AWARE THAT I WROTE THIS LITERALLY AGES AGO AND SO THERE MIGHT BE A LOT OF GRAMMAR ISSUES AND PLOT HOLES, I SUGGEST SKIPPING TO THE THIRD BOOK IF THAT'S SOMETHING THAT BOTHERS U#

1939 is when the war started. It's also when seven year old Perseus Jackson stumbled upon a camp made of of girls in Silver aiming blows at him. How is it that 1939 is when everything changed for Perseus Jackson especially in 1940 when he meets one small, frail Steve Rogers. Embark on the journey of friendship between man and dog/wolf. Thank you to @jjjmsl for the cover of the book and being my awesome editor.

Six year old Percy Jackson lives with his smelly step father, Gabe. After watching his mother die right in front of his eyes, Percy becomes a selective mute. However, that doesn't mean he's useless. The kid has something hiding behind the sea colored orbs. It only took a cup of hot coffee spilling on his expensive suit for Tony to meet the boy. Never in his life did he think he would pull over and help a boy out of the rain who couldn't even speak his name. Yet, something drew him in... and he let it.
