Percy Jackson comes to Hogwarts after given a Quest, that Albus Dumbledore and Chiron have agreed on. He is a teacher for a new subject, Muggle Fighting. Despite nobody knowing he was preparing them for an ultra war, which will unite the DemiGods and Wizard/Witches. Harry Potter is in his fifth year of Hogwarts. Things are at the beginning of the approaching war. He hears about a new subject that every fifth, sixth, and seventh year is required to take. He wonders who the professor is, and more importantly, why they needed it. *Disclaimer I don't own any of the characters. All thanks to Rick R. and J.K. Rowling. *

We won the war against Gaea, I was overjoyed. That is, until I saw blonde curls stained red. A month after Annebeth died the camp was attacked, causing a big secret Chiron kept from me to surface. My name is Percy Jackson, and I'm a wizard. (This does not follow the original plot in Harry Potter.) Percy belongs to Rick Riordan and Harry belongs to J.K. Rowling. In case you didn't know.

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

(Sequel to Percy Potter) Two years after Percy visited Hogwarts and taught for a year, he is demanded by Snape to come back and help, seeing as Hogwarts is no longer safe for students. So Percy must travel back to Hogwarts and teach students about his sword fighting techniques. Not only that but he has to teach them how to survive Hogwarts seeing as Voldemort has overthrown it as soon as Dunbledore fell off the Astronomy Tower. Follow Percy, Annabeth and Nico in their never Ending Quest of keeping as many students as safe as possible, and out of the hands of the Carrow Twins, the lords of punishment at Hogwarts. In all this mix up Harry and his two friends are out hunting for horcruxes, breaking into places people wouldn't dream of, and doing things that would've landed them in Azkaban.
