Can they trust him? Disclaimer: NO PERCABETH. I still ship it, I just wanted to try something different and if you aren't comfortable with that, please just don't read, I'm well aware that it goes against the core story but this is fan fiction, not cannon.

Another Evil Grandfather 《COMPLETED》 by League_to_Legend

Percy had his day planned: eat, spend time with Annabeth and stay out of trouble. I can assure you that nowhere in that plan included getting a visit from Gandalf and a miniature version of himself to inform him that he has another evil grandfather. Great! (note the sarcasm) Taken to Hogwarts for his 'safety', Percy's year looks set to be eventful, again. Not to mention that Moldeshorts knows of his existence, or more importantly his demigod heritage, and wants to recruit him. But first Percy has to get through the year. Can Percy make it through the year without revealing the Gods and demigods' existence? *set in the Order of the Phoenix and after The Last Olympian* *The Lost Hero hasn't happened yet* *Percy is 16* *Harry is 15*

Grandson of Voldemort (Discontinued) by gr33n_b3ans

Disclaimer: I was young and dumb when I wrote this and this story is an abomination but Im keeping it up for the memories. Perseus Achilles Jackson just wanted a normal life. He wanted to settle down with Annabeth, graduate high school, and go to college in New Rome. But when a group of oddly dressed people shows up at his door, he has to go to England, become friends with the wizards while keeping the demigod world a secret, and save to world. Again.

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]

The Time-turner Chronicles by Iwantapinkporsche

After Achieving everything you have ever want... The same time realizing that life was full of mistakes and regrets... " I am not afraid of making mistakes. But some mistakes were those that I could afford But there are some that I couldn't " Percy is granted one wish by Chaos herself. His only wish is to have his friends back. There's only one way Chaos can full-fill his wish and that is by sending him back in time to do everything again. . . . I don't own Percy Jackson or anything related to him. All I own are the plotlines and the Original Characters. I'm kinda writing this story in a different style than usual. It's gonna not be heavy on description and vocabulary but more like a plot vomit. I honestly am pretty confused myself and some parts make not make a lot of sense. This story is basically how my bff talks and is dedicated to her for introducing me to the mighty world of Wattled. Anyways hope you have a good read.I hope you leave a lot of comments and enjoyed it as much I did while writing it.

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 Final Fight (A PJO x HP Fanfic) - Discontinued by SkyeWalkerz

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. What will he do when American wizard Perry Johnson joins his year? Read to find out.......
