Percy is betrayed by his friends and the person he loved the most..he decides to leave ,to change the environment.what happens when he Hecates offers him a job...to do what he does best Protect...only this time it's a school for wizards... called Hogwarts

Percy Jackson is broken. After the Giant War, Camp Half-Blood's protective barriers were destroyed, and he was the only one who escaped. He watched his friends and family be slaughtered by an army of monsters, and he has nothing left to lose. When Professor McGonagall comes to ask if he could teach a class called Defense Against the Dark Arts in a school called Hogwarts, he agrees. But there was one thing that will be difficult- not revealing that he is a demigod. Will he keep the secret, or will the year end in disaster? I do not own the Percy Jackson series, Harry Potter series or the characters in them. They are owned by Rick Riordan and J.K. Rowling.

Percy Black lost his mother, Sally Black, at a young age, and never knew his father, he is raised by his Aunt Narcissa and uncle Malfoy to be a proper pure-blood but hes not sure he wants to be one. Hes faced with a choice (Crappy summary I know but I was never able to explain my work) Under editing

He'd finally found them. Tom Riddle's heir. A boy no older than seventeen, with hair of a raven night and eyes of a churning ocean. The wizened old man closed the weathered book. The Fates had been kind enough to let him in on this secret, one he fully intended to use to his advantage. The boy must not fall into the wrong hands. It was time to pay an old student a visit. ~ DISCLAIMER: I do not own either the Harry Potter characters nor the Percy Jackson characters used in this story. None of the characters are mine more shall I pretend they are, this is but a work of fiction. Characters belong to their respective owners (JK Rowling and Rick Riordan).

Perseus Potter was three years old when their house was attacked. His mother handed him his baby brother and told him to always protect Harry. So he did. He even went so far as to jump in front of the killing curse. Dumbledore told him that Harry was to be the chosen one and to always protect him. Strange things begin to happen when the older Potter begins to attend Hogwarts. Missing students, strange creatures, secretive teachers, and hidden parentage. It is sure to be an eventful year. Disclaimer: I do not own Percy Jackson or Harry Potter.

Percy Jackson lost his mother at a young age. From then on he was stuck with his abusive step-father, Smelly Gabe. He didn't have much. Just one good friend. This friend was Harry Potter. One day, an owl pecked on Percy's window, and his life was changed. For the better or for the worse, he's not sure. That was the day Percy found out he was a wizard. Now, Percy finds himself a student at Hogwarts School of Witchcraft and Wizardry. He also finds that he's abnormal for wizard standards. Percy Jackson is a demigod. A powerful, illegal, demigod son of Poseidon. Follow Percy as he deals with magic, training, and three-headed dogs in his first year at Hogwarts.

After the war, it was straight back to the Dursley's for Harry. But not before someone else joins the "family". During the final battle, Gaia sent one of her minions to kill Percy's mortal parents. But they weren't the only ones to die. The police, not knowing what to do, sent Percy to his only known living relative. Petunia Dursley. --- Written by: ThatOnePezz #10 in dudleydursley as of November 2019 #92 in Fanfiction as of October 2017 #319 in PercyJackson as of March 2020 #647 in jackson October 2023 #980 in percabeth as of November 2019 Being Edited by: HeyThatsAiko (Shes awesome, go follow her)

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 Jackson-Blofis family visits Sally's cousin Petunia Dursley. They meet the Petunia, her husband Vernon, their angel of a son Dudley and their delinquent nephew Harry Potter.

One night Harry's dream show him something he can't get out of his mind. He's show the night he's parent's were murdered, or so he thought. His father is alive and his mother disappeared to who know's where. But the most surprising fact might be that young Harry Potter has an older brother. What happens when 7 exchange students come to Hogwarts and Why does one look so much like Harry? (This is my first story and I'm not sure how it's going to work out so I'm just going to say sorry a head of time.)
