In this story, the Harry Potter prophecy is really about both Harry and Percy. Same old, same old.... Harry and Percy are twins, sons of Lily Evans and Poseidon. Lily and James got married when she realized she was pregnant. They both live with their muggle (and mortal) family, the Dursleys. The twins had to depend on each other (and only each other) their entire lives to survive. Everything changes suddenly as they started receiving mysterious letters... (Mainly follows the plot of The Sorcerer's/Philosopher's Stone, mostly from Harry's perspective. (3rd person POV though.)) I'm going to put this on ao3 as well at some point. Past chapters are being continually edited when I have the time to help get rid of younger me's cringe, but nothing too big will be changed without a notification about it.

Percy Jackson and Harry potter have a secret. Each other. When they were eight, Harry and Percy potter were separated. The twins were attacked while in an orphanage, one going to the Dursleys, while other goes to a squib named Sally Jackson in America. The only person who knows about Percy is Sally and Dumbledore, besides the twins themselves. So what happens when the are reunited? Will they cause more harm the help? How will people react when they find out about Percy? And what if Voldemort is on the brink of rising? Find out in Harry Potter's Twin! * Takes place after BoO, but before the Wizard War *In this, Percy and Harry are both 17 and percy is starting out at Hogwarts, but at 7th year with Harry *DISCLAIMER- I DO NOT OWN PERCY JACKSON OR HARRY POTTER

Percy Jackson always knew he was missing something, or rather, someone. When he fell in love with Annabeth, he thought he had finally found a way to fill it, but he didn't. He has kept a secret from everyone. It is one thing that causes the most problems and makes even more secrets. He was born with a rare disorder, called Hyperthymesia. It is when a person can remember everything, with very great detail. Percy knew that Sally wasn't his real mother, and that he wasn't just half human and half god. The scar on his forehead proved that theory. He also knew that he wasn't from America, but actually Europe. He kept his spell-casting secrets to himself, which came in handy every now and then, but with his kind of life, secrets are easier to keep when you're dead. Join Percy as he loses everything, but gains something important. What is Percy hiding?

Eight years ago, Percy and Harry Potter were separated. Percy was sent to live with their aunt, Sally Jackson, in New York, and Harry stayed with the Dursley's. Now they are both eighteen, and Harry has lived through a war. Percy has lived through two. Neither Percy's friends nor Harry's know about the other. What happens when the seven get sent to Hogwarts on a quest. Will the Potter twins finally reunite? Or will they miss each other completely?

Twins Percy and Harry Potter have always been freaks. Harry had a lightning bolt shaped scar on his forehead but Percy has it worse. He is a mute. Unable to speak or sing or even hold a proper conversation with anyone other than Harry who learned sign language to communicate with his brother. The Dursly's never cared until one day two letters arrive at their door. I DO NOT OWN HARRY POTTER OR PERCY JACKSON THE BOTH BELONG TO THEIR RESPECTIVE OWNERS!

Percy Jackson can't wait until school starts.I know,big shock.But he looks toward to spending time with Annabeth.But when a letter arrives saying that he needs to go to Hogwarts,his plans are ruined.He later meets his supposed to be twin brother,who is the one and only,Harry Potter.There is not gonna only be the Wizard War,but there is also going to be a quest.A saving life quest.

(A Percy Jackson and Harry Potter Crossover) Percy Jackson was hiding. This time, at least, it wasn't from mythological Greek monsters. No. He was hiding the truth from everyone. Born in England, growing in an abusing atmosphere, the older brother of "The chosen one", the first demi-wizard to ever attend Hogwarts, two times saviour of Olympus, Percy Potter had a lot on his plate. But he couldn't tell that to anyone until his coming of age, or both of his worlds would crumble, and it'd be his fault. Join Percy in this awesome story, where he will overcome the hardships of...well, being himself. TRIGGER WARNING: Mentions of Abuse, and some cursing! (Not too much, just a bit sometimes...). I own the plot and nothing more! [Won't update for a while]

Harry doesn't think much is going to happen in his final year at Hogwarts, how wrong he is. Percy has finally finished the wars and he believes he is done, but there is still another battle to be fought. Loki doesn't think his future is very bright, with chains wrapped around him in Odin's cell, but he will once again see the light. How will these three people be brought together? How will they realize their relations? How can they overcome obstacles to be with each other, and survive?

Harry and Percy are twins and are separated when they are five because they have different destinies. Percy goes on all of his quest and then he leaves to find his brother and no one ever knows about his twin. Harry never tells anyone about his twin but when he sees him again it's a big surprise. I might own a couple characters but mother then that I OWN NOTHING thxs
