Disappearances plague the wizarding world and not even Hogwarts is safe from the sinister forces at play behind the missing wizards and witches. When a group of transfer students from America show up in Hogwarts, who seem to know their way around a blade and have the knowledge to defeat creatures from Greek mythology, Harry, Hermione and Ron find themselves allying with the Americans.

When a trip to the forbidden forest goes haywire, resulting in a missing student and a demi-god without their magic, Percy and his friends become wary of who they can trust, especially with their magic not working. With a false prophecy, disappearing demi-gods being taken by the cult, and the threat of a spy inside of Hogwarts, the demi-gods find themselves allying with the students of Hogwarts to save their friends and the wizarding community from the cult. While the demi-gods scramble to find out what the true prophecy is, Harry, Hermione, and Ron try to solve why hellhounds are in the forbidden forest.

"Fate has terrible power. You cannot escape it by wealth or war. No fort will keep it out, no ships outrun it" - Sophocles.

Takes place one month after BOO and five months after Harry Potter (Battle of Hogwarts).

HP and PJO Fanfiction by Avery_flores11

Percy Jackson is finally enjoying life. The summer before college starts and his new life in New Rome with Annabeth. But the gods aren't done yet. Percy is sent with two other demigods on a special quest in a parallel universe, where he has to protect someone called "The Chosen One" from a terrible force as evil as Tartarus himself. But Percy is still recovering. Will he be able to protect Harry, finish this quest, and save this parallel universe? Harry Potter is back. Never did he think that he would do an eight year at Hogwarts. Especially after the Wizarding War. Hoping for a normal, unchaotic year fills his dreams, but of course, he wished too soon. Three exchange students from America arrive, and Harry is suspicious. Not only does strange things seem to happen around them, people begin seeing... monsters. Then, one day, Professor Trelawny speaks a prophecy. Will Percy and Harry be able to stop this prophecy? Or will this world perish and the gods along with it?

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.

Demigods at Hogwarts by OnlyHereForTheSeven

Warning- I do not own any of these characters. Spoilers for the books are in this story as well as cursing. Read at your own risk. [Edit] Omg this is so bad. Read at your own risk lmao Setup- Pretend the Apollo thing never happened, but this would be around the time of the second ToA book. After the Battle of Hogwarts, students had to redo their last year. Also, Dumbledore, Fred Weasley, Hedwig, and Jason Grace are alive. When Hecate, the goddess of magic shows up at camp half-blood, a prophecy is spoken by Rachel. Nine demigods (Annabeth, Percy, Leo, Jason, Piper, Hazel, Frank, Calypso, and Nico) must go to Hogwarts School of Witchcraft and Wizardry under cover as transfer students from America's witchcraft and wizardry school "Nimvegut's School of the Specially Gifted." I suck at describing things, so there won't be much of that. Use your imagination! Go wild! Feel free to criticize my writing, as long as it is constructive. Join me for epic Percabeth, Caleo, Jasper, Frazel, Hinny, Romione, and maybe even some Solangelo moments! (and kick Malfoy's ass moments because all demigods are persassy!)

Hidden Wisdom and Wizards || PJO x HP by alternativekitkat

**Sequel in the Wisdom and Wizards series** If you haven't read the first it's Saving Wisdom and Wizards! ~~~ Everyone believes that Percy Jackson is for once thriving. Him and Annabeth are happily married, and they have a lovely place in New Rome. It's been months since they helped Harry, Ron, and Hermione save the wizarding world from Voldemort, and Percy and Annabeth have retired from world saving duties since. At least... that was the plan. Now? Harry's scar started to hurt again and he's been receiving dreams of some old dirt lady, reiterating words that he doesn't like to hear. Hermione, Ron, and Harry now have to track down a certain two demigods who don't want to be found, and are doing everything they can to not be found.

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.]

The second Titan war and the second giant war is over. Gaea is defeated. Peace has returned to the world. Everything is back to normal. Zeus, Poseidon, and Hades are bored to death. The big three has absolutely nothing to do, no demigods to send on heroic quests, no constant worrying over their enemies, blah blah blah. As days pass, the three gets into fights more often, causing floods and earthquakes and storms and the death of many, many innocent mortals. When Hestia, the goddess of the hearth, finally loses her cool, she sends the three back to Goode.

Collision (PJO/HP Crossover) by music_and_literature

All is as it should be. Percy Jackson and Annabeth Chase can finally relax after Gaea has returned to her slumber. Both are alive and excited for their future. But what will happen to their plan of college in New Rome when two meddling goddesses interfere once again? This time it's only a job for the Dynamic Duo. The rest of the Seven have earned their peace, but apparently Percy and Annabeth have not. They find out that not only are Greek and Roman gods real, but another myth is not such a fable. Their next journey will take them to Europe--to the Hogwarts School of Witchcraft and Wizardry. Harry Potter and his friends have finally beaten the Dark Lord. Voldemort is gone and all they want is a normal, uneventful year. Returning to pass their seventh year of magical studies, the Golden Trio finds that their troubles are far from over. Two new students join the misfits of Hogwarts and Harry, Ron, and Hermione do what they do best-dig deep to uncover the skeletons in Percy and Annabeth's closet. Little do the wizards know that the demigods are already on to them, and doing everything in their power to protect their secret. What will happen when all of the cards are on the table? Will they put aside their differences, trust each other, and work together? Or will the world witness a monumental battle between the Golden Trio and the two-time Saviors of Olympus?

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! Thanks for reading!
