Collision Course (Percy Jackson and Harry Potter Crossover) by goodness_graecus

Harry stared at me. "You're just like him. Looks like you do take after your uncle," He sneered at me with an undertone of sadness," He killed my parents and tried to kill me, too. Is that what you wanted to hear? When I was eleven, eleven, He came back as one of my professors. He tried to make himself come back. But I beat him. Then," He pointed at Ron,"His little sister was possessed by the man who ruined my life. He almost got back, but we destroyed the diary and saved the muggle-borns. Then, I find out t hat my godfather was an evil mass murderer but he was actually innocent. Then, Ron's rat turned out to be Peter Pettigrew, who was Volde-" "Harry, no! You can't say his name!" Hermione burst in. She looked afraid. "We'll have to face the death eaters and we're not ready for that." "'Death Eaters'." I said in disbelief. Trying not to laugh, "Who would want to eat Thanatos?" ************* This takes place after Blood of Olympus, before The Hidden Oracle, and during Deathly Hallows. It is mostly in Harry's and Percy's point of view but a few others are thrown in. I worked really hard on this and I really hope you guys enjoy. The first couple of chapters are about 500 or so words but they get longer, I promise. If there are any spelling mistakes or grammar mistakes, feel free to comment them down below. It is an alternate ending to Deathly Hallows. Please don't kill me when you read the bonus chapter/ epilogue. In your demigodishness and all that, stay potterheads. Love you guys!

Harry Potter and the Lost Half-Bloods. *1* by waywardsolace

Hera is infamous for meddling in other people's business. But when she takes it too far, this can lead to nothing good... Prophecies will be made. Quests will be planned. Two magical worlds will finally meet. A Harry Potter and Percy Jackson Crossover *** While this is a Harry Potter/Percy Jackson Crossover, it will still make sense reading it having only read one of the series. *** WARNINGS: swearing, death, spoilers, consumption of alcohol. No self harm or suicide. (We are also disregarding the actual events of Order of The Phoenix. No Umbridge in this story!) All characters belong to Rick Riordan and J.K. Rowling (Started: 1/11/17) (Finished: 7/5/18) (Ranks: number one in #pjofandom)

Babysitting Hogwarts {Book 1} by pearjam111

"You can't seriously expect us to go to a school for magic!" "You want us to what?" ~~~~~ Dumbledore sends out a distress call to the demigods. Voldemort is back and the gods made the mistake last time to refuse the wizard's call. Chiron sends Nico, Will, Thalia and Percy to go protect Harry Potter, the targeted wizard who Voldemort wants dead. The demigods must protect and defend Hogwarts from the dark wizard, but keep their identities as demigods secret at all costs. No one must know because it could put them in danger. But the golden trio keep persisting that the new students are up to no good. They make the secret terribly hard to keep. Contains Percabeth, Solangelo, and others ----- I don't own Percy Jackson or Harry Potter, credit goes to Rick Riordan (who is amazing) and J.K Rowling (who I do not support).

Who Could Have Known (Percabeth AU)✔️ by bellaschneeb

Annabeth Chase is your average junior at Goode High School. She gets straight A's, and you will never find her sitting in detention. Her best friend since kindergarten, Piper McLean, has always been there for her, since Annabeth's mother had died when she was six, leaving it to be just Annabeth and her father. Annabeth is just like everyone else. Just another face in the crowd. But what happens when she suddenly gets tangled up with Percy Jackson, the high school heartthrob? Percy Jackson is popular. His grades aren't great and he's had a few detentions in his high school career. He is known to be a bit of a troublemaker, in a lighthearted way. His best friend, Reyna (a bunch of names I dont remember) Arellano, is always at his side supporting him since kindergarten. Reyna was there when Percy's father walked out on him and his mother, Sally. She then got remarried to Gabe Ugliano, Percy's dangerous step-father. Percy faces the pressure of being popular, always in the limelight. He is able to keep cool on the outside to maintain his reputation, but on the inside, he's struggling with the stress. But when he runs into Annabeth Chase, his life is changed. For the better. What will happen to Annabeth? How is she so life altering to Percy? Find out in Who Could Have Known. I do not own any of the characters from the Percy Jackson and Heroes of Olympus series. They belong to Rick Riordan. And yes. I drew this cover myself. I know, I'm such an artist. However the idea was not originally mine. I copied it off google. So credit goes to the original picture, whoever made that.(idk tbh) Also, this is my first fanfic so be gentle and I apologize for any cringe/errors thank you FINISHED: 6/2/18

Back in time to help fight in a wizarding war for a world she didn't even know existed. Ootp-DH Happy readings!

The Ghosts of Millennia by ninjagirlmai

Half-bloods, hunters, and wizards go east, west and descend, A god's warrior appears when the first meets their end, The bane of the gods lies with the world's first high, At the price of the cherished never seeing the sky, A parent's mistake leads to a deadly fight, Black and green destroy or make peace over white, The flower and angel reach out their changed hand, For the ghosts of millennia and the promised land... All Nico wanted was a quiet, mortal life and a high school diploma. But when a shaky peace between Hades and Demeter finally snaps, he's forced on a quest with no prophecy that quickly spirals out of control. Tensions rise until they threaten to turn into all-out war among the gods. And in the wake of Voldemort's death and a massive Ministry cover-up, the Wizarding World falls into anarchy. Ron, Hermione, and Cho are thrown into the world of the gods as they set out to save their home before it collapses completely. How can you fight when there's no enemy in sight? How can you be free when fate itself has turned against you? There's nowhere to run, nowhere to hide. Not when all of Western Civilization is on the line.

But, Percy would much rather spend it with his Wise Girl. Their job: protect Harry Potter. A seemingly easy quest, until Harry's name ends up in the Tri-Wizard Tournament. Now, they find themselves getting grey hairs, and losing sleep, as they try to keep us with the Wizarding World. In this crossover, they meet Ron, Harry, and Hermione as they try to navigate their fourth year and the Tri-Wizard Tournament. But what evil plans do they discover one Goddess has in mind? Read and find out.

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.]

Demigods Vs Magic. by KnightCrawler101

Part 1 of the "Demigods...." Anthology. Demigods and Wizards. Two groups of supernatural ability. So similar, yet so different. Ever wondered, which one would come victorious in a battle to the death? Well, it happened. Their worlds collided head-on, erupting in a swirling inferno no one could have predicted. It was survival of the fittest, the most ruthless. Two sides entered the battlefield, but only one will walk out. Percy Jackson and Harry Potter knew this. And they were ready. To fight, and to kill. "Neither can live while the other survives." Let's see who won, shall we?
