Percy had been kept behind enemy lines. Hydra lines. Hydra found Percy to be an adequate subject and started testing things in him. They wore him down and broke him. What happens when the new Percy meets the Avengers? (This starts a little before Age of Ultron and continues through that timeline). DISCLAIMER: This will be said now, and only now. I do not own any character of Percy Jackson nor the Avengers. Those rights go to Rick Riordan and Kevin Feige(?). BUT, like, half of the plot is mine. (Y'know. Otherwise how else did Percy get there?) Most impressive rank: #1 in the 'percy' tag

Percy Jackson couldn't care less what people think of him. Someone didn't like his newly dyed hair? Not his problem, look somewhere else. People think he's weird for hanging out with the friends he did? His choice, not theirs. But if they found out his secret. That'd be bad. Actually, if they found out his secrets. Yeah, plural. Percy Jackson has a few "dirty little secrets" that could mean life or death for him. He has a lot of enemies. Being a demigod does that to you. So does being an Avenger. A/N so this is one of my special AUs. Percy is a demigod. All his friends are not. He's not dating Annabeth in this one, though they are friends. I know I already have an Avengers AU, deal with it. I like to write and have a lot of ideas. Also, I MY NAME'S NOT RICK! Seriously though, I don't own the Percy Jackson stuff or the Avengers stuff. If there's OCs they're mine but that's it. Peace out.

Perseus Jackson, or, Percy Jackson. The name most monsters and demigods have heard of. The two time savior of Olympus, the destroyer of Kronos, and many other heroic deeds. But what if Percy was a child of Poseidon.... and the grandson of Lord Voldemort? One day, Percy gets summoned home from Camp Half Blood and his mother tells him that two strangely dressed people were here to see him. To take him to meet his grandfather that Percy had never known had existed until this very day. What's the harm of bringing a Grandson of Voldemort to Hogwarts? >I wrote this when I was twelve. Please don't expect much.< Completed 5/3/18
