When Wand and Sword Collide || Percy Jackson/ Harry Potter by galaxiasgreen

Percy Jackson wakes at Hogwarts. Harry Potter wakes at Camp Half-Blood. Neither know who they are, where they are, or where they come from - but when the line between demigod and wizard blurs and a sinister prophecy arises, Harry and Percy must unite with Hermione, Ron, and Annabeth before it's too late. [WINTER 2023 UNDERGOING REVISIONS] --- Harry and Percy swap roles story, with an original plot and prophecy! Altered Timeline, taking place in 'modern day', after the war with Gaia assuming everyone survived (as this was written pre-HoH and BoO) with no canon from MCGA or ToA, and around the start of Harry's sixth year, where no events of HBP have occured (i.e. Snape is still Potions Master and Draco has not been chosen to kill Dumbledore). Percy and Harry are around the same age. Chapters alternate between 1POV for Percy and 3POV for Harry. [Luth art by Rowen Satell.]

Spy on wizards and determine if they're a threat to Olympus. But the more time he spends in the wizarding world, the more tangled things become. Between dodging bloodthirsty monsters, uncovering hidden family secrets, and dealing with wizards who either fear him or want to kill him, Percy has enough on his plate. As tensions rise and dark forces stir, Percy realizes the real danger might not be the mission... but what happens if he starts to belong in a world that was never meant for him? ps: honestly I don't even think its possible to describe this story.

[1] New Beginnings: Percy Jackson, Harry Potter, and the Philosopher's Stone by ssamkayy

[1] New Beginnings: WARNING!! Story is technically complete but I started editing literally years ago then never finished so the beginning's a little funky! Percy Jackson was adopted at the age of seven by the nastiest family in the world: the Dursleys. He met Harry Potter, the most wonderful person in the entire universe, that same day. Though completely unrelated, the boys were nearly identical, a connection forming between them that would last years to come. The pair would go through life as brothers in everything but blood. Connected at the hip, these seemingly average boys had much more in store for them than they could ever imagine. A note: Percy Jackson doesn't discover anything about the demigod side of his universe until later in the second book. Just a warning. If that's too slow for you, don't read. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan. I only own some of the plot and the occasional person or place that I may create myself. WARNING When people comment mistakes, I come back and I make sure that they're fixed. So, I'm still editing.

Percy Jackson: Grandson of Voldemort by Poke_Master57

Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne
