Percy is left deeply hurt after the giant war. No tartarus rising, just percy healing. Sorry, I'm really bad at this.

He stood on the balcony, watching the city below. His trained eyes flickered from one event to the next; the angry cabbie shouting for the traffic to move; the dog walking their owner along the streets; the father trying to keep his children in arm's reach. He sighed, rubbing his hands on his arms. He saw no real threats, no monsters in the shadows and no waiting traps. It was normal. If only he could be too. I do not own anything from Percy Jackson or the Avengers. TRIGGER WARNINGS

Percy, Clint, and Natasha have known each other for a while, Percy's apartment has become kind of a safe haven for the trio. When a new threat surfaces, Percy is called in by Nick Fury to help, meaning he has to work with the rest of the avengers, whoops.

Harry Potter always knew he was different. Even by wizarding terms. He could never explain it so he stopped trying. He brushed it of but knew deep down there was something else. He knew many things like the fact that dumbledore was a manipulative bastard who payed people to befriend him. He knew the 'true' him would never belonged so he stopped trying and hid himself away. He built a wall around his heart never letting anyone in. He put on a mask and started acting like the perfect golden boy that Dumbledore wanted. Nobody noticed. Nobody cared. He didn't mind. Meanwhile the Big Three Gods are mourning the loss of the son they created together long ago when they hear word of a boy who looks like them with unique powers like theirs attending Hogwarts school of witchcraft and wizardry. They go over to the school and enrol as guests to befriend and get back their long lost son. But is he willing to just let them in? Bit by bit they break down every defence mechanism Harry put up and see the broken boy behind the invisible mask. But with the Triwizard tournament coming soon it becomes apparent someone wants him dead. When he is chosen as a champion he doesn't know what to do. Luckily the Olympians are there to help.
