Persephone 'Percy' Jackson. A simple name in the mortal world. In the godly world, not so much. In the godly world Percy Jackson was famous, praised, and adored. Why? She's save the world. Not just once, but twice! After saving the world for the second time she'd had enough. She left camp, not that she had anyone to stay for anymore. Sadly, the price of winning the Second Giant War has been high, very high. When an old friend contacts her Percy knew that even beyond the godly world and into the mortal one her life would be everything but normal. She realized that once you venture into the hero's ways, there was no going back. Now as Wonder Woman's protégé, Percy returns to help the world once again, but now with new allies. Fem!Percy Just for the plots sake, Percy is going to be 15. Sorry if any of the characters are OOC (Out Of Character)

Percy Jackson is not a perfect hero. He's a scarred, broken, and battle-hardened demigod and the only survivor of The Seven... the last remaining person in his family, all except for his baby sister. What else isn't perfect is the whirlwind of change he finds himself in. Taken in by the Wayne's- Gotham's secret protectors- he hears whispers of caped crusaders taking justice into their own hands. So what happens when he takes up a mantle in his loved ones names, vowing to protect the innocent? Battling crime with his new team and family (𝘸𝘪𝘵𝘩 𝘮𝘰𝘯𝘵𝘩𝘴 𝘰𝘧 𝘯𝘦𝘢𝘳-𝘥𝘦𝘢𝘵𝘩 𝘦𝘹𝘱𝘦𝘳𝘪𝘦𝘯𝘤𝘦𝘴 𝘭𝘢𝘵𝘦𝘳) one question still remains: Will he learn to love again? He knows what he was made to do; he was made to protect. ⚠WARNING⚠: Panic Attacks, PTSD, Abuse/Violence Publishing Schedule: Every Wednesday (hopefully o7) (DC and Percy Jackson belong to their respective creators; they do not belong to me) Rankings: #7 dccomics #105 percyjackson *Disclaimer: The image used in the book cover was made using AI USING MY OWN SUIT DESIGN.

Hi! This is a Hunger Games, Percy Jackson, and Harry Potter crossover. I am doing this for my 100 followers celebration. It's a BIG leap but I'm willing to try it. Our favorite villains, Voldemort, President Snow, President Coin, and Goodie Kronos as well as the giants are here, thinking they can destroy these heroes once and for all. At the moment, President Snow has the whole country in his massive iron grip. He is deeply upset by what happened in the Quarter Quell and even more furious that they came out alive. So now he has done the worst thing imaginable. The 76th Hunger Games. The deadliest of them all. No one knows each other except for a select few. Haymitch, Effie, Cinna, and Plutarch have a very specific plan going on for them. There are a few people joining the rebellion and they've talked it all over with them. They've planned alliances. They're just hoping this deadly game won't end the Mockingjay Mission once and for all. Hope you enjoy! Highest rankings: #1 in 76thhungergames (June 11, 2021)

Well, I was thinking that this one is hardly ever done. So, I hope you enjoy it as much as I have enjoyed writing it. It isn't done yet, of course, but I have been debating about putting this up. I didn't know if it was good enough or not. Right. Lycaon is tracking Perseus Jackson, let's see what happens! Disclaimer: Rick Riordan owns PJO/HOO. #Wattys2015

A child born from a miracle was named Perseus Jackson. His mother, a loving mortal with the gift of sight, brought together both aspects of the Ocean, combining Poseidon and Neptune into a single being, born from her love. Something never done before, nor heard of. A child armed with the powers from both personas of the sea, knew nothing of the truth. He'd inherited, not only the power to subjugate water, but to charm with his songs like the tides of the sea, an ability exclusive only to the rarest children of Neptune. He was a siren. After unleashing his powers one day, the world realized that he held much greater power than once perceived. But he had to hide it. Such authority was unwelcomed in a world where survival was a fight. One slip up and they would know that he was not normal, even among children considered abnormal- Demigods. It was the beginning of a silent song. It could heal; it could destroy. And the melody was controlled by Percy Jackson, the one demigod who wanted nothing more than peace and quiet.

**UNDER EDITING** Upon being betrayed by all his friends and cheated on by his girlfriend, Percy Jackson flees from Camp Half-Blood, broken hearted with an unquenchable thirst calling for revenge. Antagonistic, broken and slightly on the brink of insanity, Percy sought out Hecate, the only goddess who was impartial to him. She offers to send him to a school she created, safe from the destruction of the Gods- but with a price. He had to grant her one wish in exchange, whenever she wanted it and if it was in his ability to do so. Left with nowhere else to go, nowhere else to run, Percy accepts Hecate's offer. Arriving at Hogwarts School of Witchcraft and Wizardry on the 1st September as a Seventh year in solitude, Percy Jackson takes upon a new identity, a chance to start afresh. Could Hogwarts help him back to glory, and succor the hero back to who he was before? There is no try anymore. There is only do.

[Completed] After the Giant War, Percy Jackson had thought for his demigod life to be placed on standby. No more attacks from past enemies, no more prophecies to survive through, and no more near-death experiences whatsoever. During a surprise attack at Camp Half-Blood, Percy finds himself with two choices at hand: stay and survive through the endless waves of Greek monsters, or leave and save everything he loves. What he never would've predicted, is being transported into another dimension, transformed into a beast to shield him from his human appearance, and in great need to stop a war side to side with stubborn, hot-headed villagers and their "flying companions." Meanwhile, Hiccup Haddock the Third has critical problems at hand. Now knowing of the existence of a mysterious new Night Fury in the wake of Drago's attack against the Dragon Riders makes the young Chief-to-be question the reality of the Berkian's beliefs. The truth of it all comes down to an epic battle of demigods and fantastical creatures against a madman sought to destroy both Greek and Viking cultures, no matter the cost. * * A How To Train Your Dragon 2 and Percy Jackson crossover.
