Based off of a story called 'The Legend of the Son of Poseidon' on Ao3. Percy is young when he heard a voice in his head, that voice helping him kill a monster.

Peter Parker was never normal. That's why it didn't surprise him to find out that he was actually a Demi-god. Between school, superhero-ing, and finding his place in a world of Greek and Roman mythology, he doesn't have a lot of time for anything else. Percy Jackson, on the other hand, has plenty of time to try and get the oblivious and adorable Peter to notice him. This is a Percy Jackson and MCU crossover. The main pairing is Percy x Peter. I don't own Marvel or Percy Jackson. I don't own the picture I used for the cover, I just put the words on.

Percy is transported to Earth-16, as an attempt to rid him of the final battle against Gaea. But, instead of dying like she intended, Percy is turned a God at the doorstep of Atlantis. When the Light tries to destroy the world, they have a new enemy wailing on them. Trident, Hero of Atlantis.

14-Year-Old Percy Jackson just wanted a quiet school year. But when he finds himself kidnapped by monsters and himself being sacrificed to Gaia to aid in her rise, he comes to realise something. A quiet life was never for him. And if that was the case, he would tear his way through the world and live. All on his own. [Secret Quest: A Weakling's Will Has Been Cleared!] Gamer! Percy! AU!

He killed his brother, but was concealed away to another land. He gains powers and finds his long lost "thought to be dead" Mother who looked like a... 8 year old? Now at a camp where there hero is shunned, will Natsu change them, and saved them or will his demon take it all. Percy x Natsu Flame/seaweed brain perfect for every word.

Percy Jackson; Son of Artemis, Prince of Animals. Percy Jackson's mom was killed by his scumbag of a step-father. Together, Artemis, Hestia and Apollo, do everything they can to raise Percy as the greatest demigod to ever live. But danger is never far and with Percy announced Prince of Animals, what will the other gods think? Also, who in Tartarus dared to kidnap his new mom? Disclaimer: *insert sassy disclaimer about Rick Riordan owning the Percy Jackson series here.*

Ciri helped Sally Jackson with a Greek monster problem and Sally didn't have the currency of her world, so she envoked the Law of Surprises. Desperate to return her debt, Sally stayed true to her word and brought the first thing she saw when returning home. Ciri half expected a painting, a chair perhaps, even hopefully some food. She never expected to be given a child. And a boy for that matter. So as the code states, she took the boy back to her home, Kaer Morhen. Geralt was reluctant to bring in the boy. He didn't want to burden any more children. After all, jobs for Witchers where dying off... litterally. But eventually he trained the boy and even went on to preform the traditional witcher trials, like the Trial of Grasses. Much like Geralt, the boy also went through extra mutations, though due to him not completely being human, it didn't effect his skin nor hair, well, not completely. At the age of 18 he returned to his home, and a war is brewing. A war between humans and monsters. (The prophecy follows Percy's brother's age, not Percy) I don't own Percy Jackson, The Witcher, nor any characters involved unless their an OC. Rick Riordan owns Percy Jackson and Andrzej Sapkowski and CD Projekt own The Witcher.

[I don't own PJO or HOO Rick Riordan does] Percy Jackson Percy was betrayed so per usual in my stories He leaves and becomes stronger, fighting monsters and such One day while in the forest a deity as old as time itself aproched him This deity was Chaos, Creator of the Universe. He was going around to different planet's and people and giving them a different spirit to hist their body He has been watching Percy for a while and was debating on a multitude of things. He wanted him to be the commander of his army His assassin Or his sin. Percy grew tired of wars and didn't ask to be the commander, he wasn't cut out to be an assassin so he was thinking of turning down all of his offers He then re-thought. The sins. The Seven Deadly sins Wrath Greed Lust Envy Sloth Gluttony And pride. He decided to be a sin. One of the strongest in the Universe Chaos took him to Utopia his first planet. Where one of the sins would choose him... Little did he know the mess he was about to get himself into...

Percy Jackson is as normal as can be. Well, as normal as a kid with ADHD in high-school can be. He is only always seen with two students in his school, his best-friends Grover and Rachel. Percy has a crush on his school's number one bad boy/quarterback Nico di Angelo, also known as Ghost King. Percy had long accepted that Nico will never notice him, but still continued admiring him from afar. What happens when one day, Percy gets a blue rose and a drawing of himself in his locker?
