Sally died protecting her nephew Harry Potter. Lilly and James Pottor come back home to see her dead and Harry crying. But they notice something else is wrong. Their nephew Percy is gone. All rights go to Rick Riordan and JK Rowling So in this story there is going to be a lot of people who aren't dead. There's Snape, Sirius, Lupin, Tonks, Lilly and James (of course!). Also Fred not going to be dead because separating the Weasley twins is like separating the Stolls! Blackjack and Percy are going to seem more close in this. I've only seen the movies to Harry Potter so sorry for incorrect information! Just tell me and I'll try to fix it!

Percy finds out that his mother is actually a wizard. Now he must go to Hogwarts and compete in the Triwizard Tournament representing camp half blood whilst trying to keep Harry safe. There's just one problem, making sure that the Wizards don't find out about the Gods. Who will win the competition? Will Percy keep his secret safe? Will the dark lord rise once more? First part released: 1st April 2015 Disclaimer: All rights go to JK Rowling and Rick Riordan.

Harry Potter is used to being the Hero of his world. He and every other wizard believes he is the destined savior of the world. Now that wizard world knows Voldemort is back Harry is going to need protection. Percy Jackson has finally defeated Gaea and saved the world yet again and thinks things will start to calm down. Unfortunately for him, he is that protection. Except he can't do it alone. He is going to need the help of six certain people. Worlds collide in Demigods at Hogwarts. (Guys I suck at summaries. I swear the book is better.)

When Percy is summoned home from camp to see some weird people on his couch, let's just say he's confused. When he finds out that he has another evil relation, he's not happy. Well, off to Hogwarts. Harry is astounded. Voldemort- the lowlife scum of the wizarding world- has a grandson. Now Dumbledore wants him, Hermoine, and Ron to get him, and become friends. Harry must be crazy because he agrees to go. Set after PJO but before HoO ( I want him 15/16) and during OoTP Check out my other crossover: Percy Jackson - the New Hogwarts Teacher Cover created by @Emer28702000

When demigods find out that wizards are real, and they are wizards to then they go to hogwarts. They meet the golden trio. But will they get along? And does everything go to plan

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.

The order of the Phoenix asks the demigods in America for help to defeat Voldemort. Now Nico, Thalia, and Percy are going to Hogwarts to avoid being thrown into another war. Will they be friends or enemies with the golden trio? Will they be able to avoid the war or will they be at the center of it? And for which side will they fight? Disclaimer: I don't own Percy Jackson or Harry Potter. All rights go to Rick Riordan and J.K. Rowling. Except the plot. The plot is mine.

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

Percy Jackson just won his own war, and now Chiron wants to send him, Annabeth, Nico and Thalia to a wizard school in England? Not to mention it's called Hogwarts. What kind of name for a school is that? Their quest is to protect some guy named Harry Potter, and stay undercover. No one can know he's a demigod. Well, off to Hoggy-Warts. WARNING: I wrote this when I was twelve, and it has lots of hate towards Harry & Ron in the beginning, even though I love those guys. It's not very good, sensible, or developed!
