Loki always keeps his promises. No excuses. This time shouldn't be any different, right?

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

Everyone knows Steve Rogers is Captain America. But when Tony finds him arguing with a blonde girl of about 18 in their new tower, the truth comes out. Annabeth is missing her Seaweed Brain, who disappeared long ago on a mission, falling to his supposed death with another man who has turned up alive. Bucky Barnes. But where is Percy? ***DISCLAIMER I AM NOT RICK RIORDAN OR STAN LEE OR WHOEVER WROTE THE COMIC BOOKS I ONLY OWN ANY OCS THAT COME UP, NOBODY ELSE!***

After enduring Tartarus and then winning his second war, Percy Jackson is the Champion of Olympus. However, he didn't come out of the war his normal self. He came out broken and with flashbacks and nightmares haunting his mind. In order for Percy to get better, the gods push him to stay with the Avengers. But the enemy isn't going to wait for Percy to defeat his demons. A darker power is stirring. A darker power so fearsome and strong that even the gods and goddesses are scared. Scared enough that this time, they want the Avenger's help. A third war is coming and whether or not they will win isn't clear. (Complete)

Dan is sick and Phil is suffering - so what the hell are they supposed to do now?

They say he was born in hell. He is the definition of fear and terror. Titans weren't foolish enough to challenge him. The Olympians believed it was the creator Chaos himself from the power that pulsed from his body. He is even feared by death himself. When the threat of Erebus rises, the Olympians prepare for war. Unfortunately for them, their old hero is on the enemy's side and will stop at nothing for his revenge. He is Percy Jackson.
