What if Percy, Annabeth and Thalia aren't just demigods. What if Percy's mum is a witch? What if Annabeth's Dad was a wizard? What if Thalia, though her mum is mortal, what if she is a witch? What happens when they go to Hogwarts and be friend the golden trio? Be prepared for a whole year of trouble, fun and secrets. I do not own Percy Jackson or the Heroes of Olympus. Rick Riordon does. I do not own Harry Potter. J.K. Rowling does

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

Percy Jackson had the life everyone wanted, he was the hero of Olympus, respected by the most powerful beings, and had the best of friends. However, fate works in cruel ways, and everyone around him began to change. His friends had abandoned him, his girlfriend betrayed him, and our hero was banished to the darkest depths of Tartarus by the gods he had given so much for. What happens when he returns stronger than ever? Will he want revenge, or is he beyond repair?

His time at Hogwarts is over, but the fight against Voldemort has just begun. Straight out of a barely complete Physical Therapy, Percy finds himself in the-middle-of-nowhere-snow-land with only a backpack and book, no knowledge of how he got there or how to get out. His test from the fountain of fate has finally begun and he has to solve whatever mystery that shrouds Emerson Earthfire. Facing the most difficult time of his life, Percy has to fight against death and the deadline of the fast approaching war, alone until the appearance of an unlikely face. All Harry Potter knows is that the place he called home is no longer safe; Hogwarts has been compromised. On the run with Ron and Hermione, the only safe place is Number 12 Grimmauld Place. Avoid capture, destroy Horcruxs, stop Voldemort, that is the mission. He doesn't have time to think about their friends at Hogwarts, the Order of the Phoenix, and-because it pains him too much to-Harry definitely doesn't have time to think about Percy Jackson's death. Avoid capture, destroy Horcruxs, stop Voldemort. Draco Malfoy needs help, and more than ever, he needs his best friend, Percy. But Percy's dead, he has to keep reminding himself of this, to stop the pain he feels when he forgets and has to remember again. Now, he's all alone in the evil life his father's trapped him in, wishing so much he could change it. Forced to follow the evilest wizard in history and wear a tattoo that hurts him to see, Draco's running out of time to find a way out. What's on the other side is something he could have never prepared for. This is a SEQUEL and will make a lot more sense if you read the first book. BUT, you don't have, though I encourage you to.

Perseus is the son of the Roman goddess Lupa and Lycaon the king of werewolves. Perseus is raised by the Hunters of Artemis. Takes place before and after the prophecy of the seven. Follows Percy's life. He is part of the two prophecies. Percabeth! Cover art not mine! I do not own Percy Jackson. All the characters except for the ones I created all belong to Rick Riordan

When Percy loses almost everything, he cuts off his remaining ties and heads off into the clueless mortal world. Percy builds a new family but is struggling to protect them. Percy must pull himself together to gain the trust of the Avengers themselves... But will Percy trust them? When all seems lost... Will there be a light to guide Percy... Or rather, 7 lights?

Voldemort is back and Percy, Thalia, and Nico are sent to Hogwarts to help with the war against the dark wizard. Will they be able to make it through the school year without revealing themselves? Placed after the giant war and in Harry's 5th year A/N: The writings kinda suckish in the first few chapters, stick with it, it gets better. Edited as of: 2/13/17

In the worlds of Harry Potter and Percy Jackson, Harry is eating dinner in the Great Hall and Percy is being chased by monsters. How do the two worlds meet? Simple. Percy falls through the enchanted glass ceiling of the great hall unconscious. Percy doesn't know where he is, only that he's being chased by monsters. Fighting in the sky with Blackjack, there are only two monsters left. The monsters hit Blackjack and Percy with their clubs upside the head, rendering them unconscious and spiralling in different directions. As Percy plummets downwards, Riptide slips out of his hand and slices through the two remaining monsters, killing them out of pure luck. Or is it pure luck? When Percy wakes up in the Hogwarts infirmary and tries to leave, Hecate tell him to stay and protect the Boy Who Lived and his two closest friends. Except how is he supposed to protect people that don't trust him? Disclaimer: I do not own PJO, HOO, or HP.

This takes place in an AU where the seven have died and Nico, Reyna and Will are sent off to Hogwarts.

Percy Jackson was made from the hearth, Vesta and Neptune had to keep him a secret so they sent him away to keep him safe. Convinced he was abandoned the demigod strays farther and farther from the orphanage, only to meet a silver-eyed goddess.
