The war with Gaia had finally finished, there were many injuries but many survivors. Percy had justgot home to his mother Sally Blofis to discover a horrific secret about her past... Then he hear "Stupefy" and everything went black... Disclaimer I don't own any of the PJO or HP characters only the storyline is mine.

Harry has a little brother

Percy Jackson was nineteen, nearly twenty years old and was the boss of an aquarium of his own. Demigod life put behind him, he moved to the United Kingdom to start a new life. He didn't know was that one day he would meet an eight year old abused Harry Potter. Unaware that he once again messed with fates plans, Percy Jackson adopted Harry Potter and with some help from his friends, created a wizard that can change the course of the future.

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's first trip to America was one to be remembered, His father the great and powerful dark lord had to go on a negotiation trip to New York city and had taken him along. But Percy knew it was more then that. The way his father keeps stealing glances at him, like he had figured out a big secret and didn't know what to make of it. And something felt... different, the magic in the area felt so intense, the air practically crackled with power. Well.. that and the odd lightning strikes and storms. And he was sure someone was stalking him. #SEQUEL TO PERCY JACKSON, SON OF VOLDEMORT#

Perseus Jackson was left in an orphanage in London when he was just one years old until a man with cold red eyes and a snake as a familiar came and took him away. What will happen to the world's most loyal hero? will he create his own path? Or will he rule the wizarding world as the heir of lord Voldemort. #PLEASE BE AWARE THAT I WROTE THIS LITERALLY AGES AGO AND SO THERE MIGHT BE A LOT OF GRAMMAR ISSUES AND PLOT HOLES, I SUGGEST SKIPPING TO THE THIRD BOOK IF THAT'S SOMETHING THAT BOTHERS U#

After his quest in finding the lightning bolt Percy Riddle was hoping to have a nice and peaceful year in Hogwarts. What a laugh. An eleven year old girl has his father's diary (which isn't actually just a diary), there are bloody writings in the walls of Hogwarts and whispers from within them. Grover has also (once again) been kidnapped (you just can't be more careful can you buddy?). And who is this oddly dressed black haired girl he keeps seeing in his dreams?
