The Giant war is over and Percy Jackson is spent. Finally there's a chance he can be with Annabeth for a while and he eagerly awaits the summer they have planned together. But when Hecate shows up and sends Percy on a new quest, it could be the by far stupidest thing he has ever done. He must be the new teacher at Hogwarts. Harry Potter has been attacked by the Ministry and Dementors. If that wasn't enough he now has a new teacher. But he is like, a 17 year-old kid. Who looks a lot like him. It's Harry's 5th year and he is now a nutter to the wizarding world. So when he sees the kid show up at Number 12 Grimmauld Place, he starts thinking he might actually be mental. The new kid turns out to be a teacher. The teacher of DADA. But Umbridge is still there- as the High Inquisitor. It seems she watches the new teacher-Professor Jackson- a lot more than the others. Something is off about him. And the Golden Trio always tries to find out what.

Percy Jackson goes to Hogwarts to protect Harry Potter. Then he ends up in the Triwizard Tournament. Harry soon becomes friends with him, but a secret could break them apart. What happens when Harry finds out Percy's secret? Does anyone else know? What will Percy do? Will I drop a few crazy bombshells? Am I asking too many questions? Probably, just read. My first story so DON'T JUDGE MEH! AMAZING cover by @HaileyLongbottom394

Percy finds out that his grandfather is Kronos! And voldermort! Yay, best grandfathers ever Note: disclaimer: I am not Rick Riordan or J.K Rowling and I do not own any of their things

After the giant war Percy is left alone in the world. He decides to leave camp and goes to London where he meets the goddess Hecate. In London he is asked to teach at a magic school, Hogwarts. Set after the giant war (the giant war didn't end like it did in BoO so there are no spoilers) and after the war against Voldemort.

NO LONGER CONTINUED. NOT GOING TO PUBLISH CHAPTERS

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.

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

Percy thought his life was going to be normal for a change after the Giant War . . . or as normal as demigod's life could get. It wasn't till his mother disappeared that he truly realized how messed up his family truly was. Going to Hogwarts was the last thing he wanted to do, but Nico and Annabeth thought it was safest. Never in a million years had he thought his mother could be related to such a psychopath. And to top it all off his name mysteriously appeared in the Goblet of Fire. Wars he could handle - piece of cake! Another evil grandfather out to get him . . . now that was stretching his patience too far.

When Dumbledore discovers the grandsonson of voldemort, things start to get a little weird. He didn't mean for it to happen, it just did! Percy didn't want to be the grandson of another old cart who wanted to take over the world, it just happened. What happened when Percy goes to Hogwarts?
