Demigod Diaries: The Mad Usurper by gerbre

A few years after the war with Gaea, the demigods face another series of problems. A new wave of maleficence headed by someone only known as the "Mad Usurper" is coming for the gods and demigods. In addition to that, their personal problems are also in the way. Will the heroes be able to resolve their problems and stop the Mad Usurper? How will the succeeding events affect Olympus and their fellow demigods? All persons, monsters, gods or demigods living or dead in this fanfic is purely fictitious...or are they? Any event/s about to happen or happened before is/are purely coincidental. This is a fanfic of PJO and Heroes of Olympus in case you're wondering. FOREWORD: The comment section is always open if there are suggestions about the writing style, threats, bashing, reactions, etc. My co-editors are Keira_Viresse and enigmaticyouniverse. Take time to read their amazing works too. Enjoy reading!

Percy Jackson: Grandson of Voldemort by Poke_Master57

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. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne

THE GOLDEN QUARTET ━━━ percy jackson by ryleeoverhere

❝Uh, mom, why are Gandalf and company lounging in our living room?❞ Percy Jackson is about as normal as it gets. Or so he wishes. But instead, he's the son of the god of the sea, has saved the world a grand total of two times, and now has a second evil grandfather? You'd think one was bad, but nope there's another one. Did I mention the wizards? Harry Potter is frustrated. Dementors coming after him, the so called Order of the Phoenix, who won't tell Harry anything, except for one thing. Just one thing. That the grandson of Lord Voldemort himself is going to live with them? [discontinued]

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!

WARNING: This story is probably going to be inconsistent and have a good few mistakes. Also probably swearing and maybe some other things but I'll put trigger warnings at the beginnings off chapters. Most will have swearing of some sort. The 7 died and Percy killed Gaia. He was tortured by Tartarus but ended up friends with him and all monsters. He is immune to all poisons, can withstand major blood loss, can hide his emotions expertly, and feels nearly no pain. What will he do when Hecate asks for help? Harry has nowhere to go after the war but then Hogwarts opens its gates to him once again. With Gryffindors behaving like arrogant pricks, Snape back from the dead, and the love of his life bing in Slytherin Harry is in a bit of a pickle.

Slytherin's Heir by Borntosingwithdrama

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.

Saving Wisdom and Wizards || PJO x HP by alternativekitkat

Being a half-blood isn't easy, and it doesn't get easier. Of course, fighting in two wars and being drafted into a third doesn't help. But there are those lucky ones. The ones who survive and move on, have families, education, life. Percy Jackson is not one of them. He's a demigod and apparently, a very powerful and hated wizard. Percy is tasked with helping the Wizard World, and protecting Harry Potter, which is hard to do when Harry wants nothing more than to kill him. ~~~ *Completed* Sequel is up! Check out Hidden Wisdom and Wizards :) ~~~ Rewrite is also up! Same title, but with gray cover. I highly recommend checking that out as well! ~~~ Highest Rankings: #1 Percy Jackson #1 Percabeth #1 Annabeth Chase #1 Wizards #1 Dark!Percy #1 Heroes of Olympus #1 Rick Riordan #1 PJOHOO #2 Crossover
