Percy Jackson had survived the unsurvivable. He had faced off against Liam and the Titans and the war had been won. But the battles left their marks on him and the other campers. Not even a day after the war ended, Percy is called on to help aid in another war of a more magical sort. When there is a friend suffering from a prophecy equally as ugly as the one he'd just gotten away from, who is he to take a break? Especially when that friend is Harry Potter. During their sixth year at Hogwarts School of Witchcraft and Wizardry, the recovering demigod has to prepare for another war of life-altering proportions, helping in the search of one of Voldemort's weak points - Salazar Slytherin's Locket, and one of several Horcruxes. Follow Percy as he deals with magic, monsters, and an upcoming war in his sixth year at Hogwarts.

Percy Jackson is a 23-year-old aspiring author. His whole life revolves around writing and his family. When he finds out that his little brother has developed cancer, his whole life turns upside down. Percy needs to make money and fast. Annabeth Chase is the young COO of an architecture company. After her last assistant quits, the job for a personal assistant becomes available. Despite everyone's warnings, Percy decides to apply for the job. However, Percy Jackson never expected to receive a boss like Annabeth Chase.

After the incident with Annabeth that caused her death, Percy shut himself out of the world for six years. After that, he's changed and the world had changed. Olympus and Camp Half-Blood are in a mess without him, and now they're facing a threat which would decide the fate of the world. Would Percy save his old life or would he leave everything behind? Post HoO.

At first, Percy thought he was going to live an easy life after years of constant battle and danger. But as fate would have it, it wasn't meant to be. The veil that separates mortals from the mythological world, the Mist, has suddenly stopped working and everything was laid bare for mortals to see. Attempts to ensure coexistence were made, but mortals quickly concluded that demigods were a danger and sought to eradicate them from the Earth. And so, demigods were now on the run as they were hunted by Crusaders that look to dispose of the world of demigods.

A/U. The seventh child of Kronos and Rhea, hidden from all of his siblings for three millennia. Now that he's discovered, Zeus threatened to kill the god, endangering Artemis in the process. With a solemn declaration, the Goddess of the Moon finds her fate more seemingly intertwined with the recently discovered Olympian. Would destiny twist their fates as such that would lead to their own demise, or would the two triumph over the challenges that are headed their way?

*NO GREEK MYTHOLOGY* Perseus 'Percy' Achilles Jackson was always in foster care. Never knew his real parents or how he got his powers of water and shadow. From a young start he learned that no one is nice and that once people are home they show their real colors as a world class jerk. He doesn't remember how many homes he was kicked out of or how many he ran away from but he knows that he is never there for a full year. At 4 year olds he learned how to take care of himself and earn money, he learned to cook food and how to pickpocket people along with who has the most money on the streets. Now 12 years old he is in New York City living with yet again another abuser named Gabe something (he never bothered to learn last names), he was in New York where the Avengers were. What happens when Percy tried to pickpocket from a blond spy and is caught? This story contain Norse demigods This story mentions abuse This story does not contained sexual abuse This story is going to be a bit sad This story was asked by @booklover121345 NOTE: THIS BOOK IS PRETTY MUCH A CLUSTER F AND I HAVE NO IDEA WHAT I WAS THINKING WHEN I WROTE THIS WEIRD BOOK NOTE: This book is weird and I have no idea where my brain went with it and information contained, you are allowed to skip over if you very much disagree with.

Six years since he left. He disappeared from the demigods, the gods know where he is but don't tell their children. He moved on after his love died. Only his cousins are allowed to contact him. This is Percy Jackson life, his code name is Riptide, and he is an agent of S.H.I.E.L.D...that meets the Avengers too. Includes Agents of SHIELD later on in Season 1 DISCONTINUED

After his quest in finding the lightning bolt Percy Riddle was hoping to have a nice and peaceful year in Hogwarts. What a laugh. An eleven year old girl has his father's diary (which isn't actually just a diary), there are bloody writings in the walls of Hogwarts and whispers from within them. Grover has also (once again) been kidnapped (you just can't be more careful can you buddy?). And who is this oddly dressed black haired girl he keeps seeing in his dreams?

Annabeth breaks up with Percy and he gets wasted that same night. 9 months later he gets a little surprise.

When Percy, his mom, and step-dad go to Star City for his mom's author expo, Percy meets the Green Arrow when a monster attacks the city. But they capture Percy, thinking he's a rogue metahuman of a sort. But when Percy escapes and meets Team Arrow for the second time, they need his help. Will Percy help them? And will they team up, and they go through the thrilled chase to find another villain, who goes by Prometheus? Will Percy and Team Arrow become friends? Or will they become enemies along the way? PJO x ARROW crossover I don't own any of the characters. After HoO and during season 5 with Prometheus.
