Percy Jackson has always been different.  Even by demigod standards.  

He had normal demigod problems...dyslexia, ADHD, and monsters.  

He had normal problems.  Bad grades, getting into trouble at school, that kind of stuff.

But he was also the son of Poseidon, the subject of two Great Prophecies, the Hero and Savior of Olympus, one of the only living beings...gods included, to survive Tartarus, one of the only demigods to bathe in the Styx, and one of the only beings that ever held the sky.  All that makes him different.

But now, he was about to delve further into abnormality, when he finds out he has another evil grandfather.  This time it isn't an evil, immortal, all powerful Titan Lord that likes eating his kids...just a powerful, evil noseless creep with a freakish, yet hilarious name that somehow makes people flinch.

And now, Perseus Jackson, the son of Poseidon, is about to go on his strangest adventure yet...going to Hogwarts School of Magic.  Yet another tragically hilarious name.


(Look, I know there are a lot of these and it's pretty classic, cliche, and slightly overused, but I promise you readers that this story does not fit into that mold.  Give it a shot, and see how it goes.  But if anyone steals my plot...I'll feed you to my pet Hellhound :). )

The Prophecy That Changed the World by Marichfrlife
16 parts Ongoing
Percy Jackson is an average kid. He's bullied in school, has no intrest in learning math, and hates geometry. He's dyslexic and has ADHD, but his mom says thats normal, and she's always right. Just because he can read the weirld language his mythology teacher shows on the board doesnt mean he's weird, and its not like he told anyone about it. So yeah, he just a normal, average person...until he's transported back in time. Now he's fighting monsters he never thought he'd fight in Ancient Greece, because the gods and godesses sent him on a quest that could destroy the world if he fails. No pressure, but at least Percy's not the only one stuck saving the world, his emo neighbor Nico and "responsible" friend Jason are stuck with him too. Percy just wishes he could sleep properly again, and who is the cool blond girl that transfered to his school? Why does she look so familiar? Sorry in advance for bad gramar, this is my first fanfiction about an aready existing topic and I hope people like it. (Future author here, I just relized the first time I published this I spelled prophecy in the title wrong, sorry.)

Yup. Me, Percy Jackson, a monster? Ha. Could never be me. ... Funny story, actually- A/N Hi!! Tanks for checking out meh story :D Dis is NOT a Chaos story that actually has Percy as an overpowered revenge seeking super emo person that has trust issues. Well maybe the trust issues thing is true, but still I kinda hate those cliche chaos plots but hey Me personally They're pretty good So I added SOME chaos in here but it's just a side thing The rest, well, the rest is pretty much my own idea with plot twists that'll probably kill your soul (hehe), murder(mwahahahah), some crossovers, and plain good old persassy too. Enjoy!

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
The Moon's Shine (PJO) by TheDarkGamer123
71 parts Complete
Being one of the few survivors of the Second Giant War, twenty-two-year-old Percy Jackson is crushed. Nobody seems to be an ally anymore. Everyone appears to think he knows it all: How to deal with all the losses, how to deal with all the empty seats at the dining pavilion, and how to deal with the guilt. The guilt that he could've saved more people. Scarred and feeling like he isn't useful anymore, Percy doesn't know what to do with his life-until he meets a person who makes his heart beat again. But of course, like anything else worth living for, spending time with this person isn't as easy as pie. Follow Percy Jackson, the powerful son of Poseidon as he goes through an adventure full of drama, heartache, deception, and love. I'll try to make this as non-cliche as possible :) Rankings: #1 in percyjackson 8/14/23 #1 in theseven 3/10/24 #1 in pertemis 3/9/24 #1 in perseus 8/28/23 #1 in chb 8/28/23 #1 in pjofandom 10/30/23

All her life, she had loved. She embraced the love she received and shared it with the world who seemed to lack them. Loving has always been the one thing no one could take away from her. But loving was the one thing that could take her away from the world. Loving came with a price- undeniable loyalty. Personal loyalty. A fatal flaw that would lead to her demise. A flaw that even the strongest heroes could not recover from. A flaw that they could not change. Because with loyalty, comes the pain and suffering. With the second war brewing within the shadows of the world, comes the hardships and suffering. It was strange how ignorant humanity could be. The little things that people overlook, the ignorance they have that would ultimately lead to their demise. The pesky little problem within the Wizarding World was no match for a demigod- much less the daughter of Hades. But when two worlds collide- only then, did she wish she never overlooked the little things. That was her first mistake. How do you face death and darkness all your life and not succumb to it? But maybe, just maybe, it was time to give up. ▶︎ •၊၊||၊|။||||။‌‌‌‌‌၊|၊၊||၊|။||||။‌‌‌‌‌ • 00:23 ----- 𝗹𝗶𝘁𝘁𝗹𝗲 𝗳𝗿𝗲𝗮𝗸, harry styles ❛ somehow you've become some paranoia, but your gift is wasted on me. ❜ ⋆˖⁺‧₊☽◯☾₊‧⁺˖⋆ HARRY POTTER - The Order of the Phoenix HEROES OF OLYMPUS -

Percy Jackson is dead. That must be hard for you to hear, huh? After all, you knew him better than I did. Maybe this story would have gone a lot differently if he was around. But he wasn't. It's the year 2030. After all the mythical wars and battles the universe was beginning to calm down. But Percy Jackson is dead now, so there is no one left to keep it on order As a demigod life is kind of hard. Killing weird stuff that want to kill you for the fun if it, or because they feel slightly peckish? To that I say, such is life. My name is Xylee Cross; Daughter of Poseidon. I'm now his only demigod child. The expectations for me are pretty high being the half sister of THE Percy Jackson. Ah, yes, another cliche story about a daughter of Poseidon. You may ask "Xylee, why can't you be original?". Well, my birth had nothing to do with originality. It had to do with the fact that sometimes gods have children, and those children end up with a lot of work, many messes to clean and a lot of mistakes that probably won't be dealt with the easy way. Sounds fun, right? This is the one where I receive a prophesy that leads to a quest. That quest leads to a lot of confusion and irritation, but in the long run it leads to the world being saved. -------------------------------------------------------------------------------------------- Okay, so most of the characters are mine. This idea of this book was inspired by the amazing Rick Riordan. Please don't take this idea or this story or I swear I will hurt you.
