Blue Cookies and Viola's Milk by Jinglebells852

When Nico has to shadow travel himself, Percy, and Annabeth out of the woods one Capture the Flag, he goes somewhere unexpected. What happens when the worlds of Percy Jackson and Fablehaven collide? (All canon ships including Percabeth, Solangelo, and Brackendra, takes place after BoO and Keys to the Demon Prison) I only own the plot I write, Rick Riordan and Brandon Mull own their respective stories, I own no characters or plot other than the plot I create in this fanfic.

The Spirits of the Universe (PJO) by anagnostiswrites

Percy Jackson is tired. Tired of the frivolous battles. Tired of all the quests. Tired from the countless deaths. But when something devastating hits home, he knows he's tired of another thing: the entire Greek world. And when two voices appear, he thinks he's going insane. But, of course, he can't take the simple way out. In comes Poseidon, giving him a chance to heal. He happily takes it, expecting no more drama in his life . . . But with a city flooded with duplicitous citizens, assassination attempts, and a world-ending prophecy, can he really find peace?

Percy Jackson, Son of Chaos - Edit by Cetirus

Percy is betrayed when Nick Waters, a son of Poseidon and Percy's half brother, comes to camp. Loyalties are tested and enemies are made. Sally abandons him to start a mortal family. Even with the friends he still has, Percy decides to leave the place he is unwanted. He is summoned on Olympus and accused of things he didn't do. Some believe him but most are just eager to get rid of him. But when will they learn, you can't get rid of Percy that easily. He is met with some gods and the creator himself, who gives him a chance to go back in time and relive his life but not as a son of Poseidon but a son of Chaos. What will Percy find in the new timeline? Friendship? Love? But one thing's for sure, he will definitely have his revenge on those who wronged and shunned him. I own nothing except the OCS and plot. PJO belongs to Rick Riordan. Full credit for this story goes to MidnightIridescence. I found the story, and decided to make a few edits to improve overall quality. Full credit to them! :)

Commander Alpha by koroy003

Commander Alpha of Chaos's Army (PJO/HOO Fanfic) Highest Ranks: #1 in Percy Jackson; #1 in PJO Percy Jackson. Savior of Olympus. Hero of the century. For a while, he's the most respected demigod out there. But it's surprising how fast things can change. Brendan, another demigod, appears and starts spreading lies about Percy and soon has the whole camp against him, except for Percy's closest friends. But soon, even they begin to have their doubts. In a turn of events, Percy runs from his home and into Chaos, becoming the commander of Chaos's army and the adopted son of Chaos. It's been 500 years, and Percy loves his new home on Chaos's planet. But, when trouble arises on Earth, Percy and his army are forced to face their pasts and Percy has to defend the ones that betrayed him. This story of betrayal, love, the everlasting bond of a family, and forgiveness filled with endless twists and turns will keep you entertained and inspired until the very end. - - - All credit goes to Rick Riordan for PJO and HoO and all of the characters, except the ones that I make up, duh!

Another War by LANALLAMA05

Another war is coming. Percy is thrown into that war. What's new? Well, that would be the fact that wizards exist and a few goddesses like to mess with people's lives. Oh, wait. The last part wasn't new. ¤¤¤¤¤ Percy woke up in an unfamiliar bed. He grunted, clutching his head as new information flashed into his brain. Light. Dark. Spells. Potions. And. . . Nico? ¤¤¤¤¤ Set in Harry Potter's 4th year. Set after BoO I do not own Percy Jackson and his Greek world. I do not own Harry Potter and his Wizarding world. I do not own any of the art on the cover.

Persephone Jackson, after winning two enormous wars, got left behind broken and alone. Betrayed by her most loved ones, the scars ran deeper than even the ones from Tartarus. Everyone, from Chiron to even Annabeth and the others Seven, turned their backs on her. Decided that it was better leaving her demigod life behind, she ran away. Persephone Jackson, Heroine of the Olympus, my ass. Let's have fun and be a villainess instead. I do not own anything besides the plot☀︎ Started: 01/07/21 Ended: 07/07/21

Betrayed|A Perthena Story ✓ by sfridley

Please don't read this. This was my first fanfiction and it has a lot of cliches, my writing has also improved dramatically. If you still want to read more of my Percy Jackson fanfictions, please check out "the legacy (pjo)" In "Betrayed," Percy Jackson finds himself betrayed by those he once trusted. Seeking an escape from the pain, he implores the gods for a release, only to be handed a new purpose by Zeus himself. As Percy grapples with his shattered trust and newfound responsibilities, a mysterious threat emerges. The gods and goddesses, pillars of Olympus, begin vanishing inexplicably. Now, Percy must navigate a perilous journey alongside the Seven Heroes of Olympus to uncover the truth behind the disappearances and prevent a looming catastrophe. Together, they embark on a quest filled with challenges, betrayal, and the ever-present danger of an unknown adversary. As the stakes rise, Percy's resilience is put to the ultimate test. Will he not only survive the betrayals that scarred him but also rise to the occasion and become the hero Olympus needs? "Betrayed" is a riveting tale of redemption, camaraderie, and the enduring strength found in the face of betrayal, as Percy and the Seven Heroes strive to save their world from an ominous threat that could unravel the very fabric of existence. -𝚠𝚛𝚒𝚝𝚝𝚎𝚗 𝚋𝚢 𝚊𝚒 All of the PJO and HoO characters belong to Rick Riordan.
