Percy, Annabeth, Frank, Hazel, Jason, Piper, Leo, and Nico are going to Hogwarts to discover more about the wizarding world, but they have to keep undercover! What will happen as the (undercover) demigods and wizards meet?

Harry stared at me. "You're just like him. Looks like you do take after your uncle," He sneered at me with an undertone of sadness," He killed my parents and tried to kill me, too. Is that what you wanted to hear? When I was eleven, eleven, He came back as one of my professors. He tried to make himself come back. But I beat him. Then," He pointed at Ron,"His little sister was possessed by the man who ruined my life. He almost got back, but we destroyed the diary and saved the muggle-borns. Then, I find out t hat my godfather was an evil mass murderer but he was actually innocent. Then, Ron's rat turned out to be Peter Pettigrew, who was Volde-" "Harry, no! You can't say his name!" Hermione burst in. She looked afraid. "We'll have to face the death eaters and we're not ready for that." "'Death Eaters'." I said in disbelief. Trying not to laugh, "Who would want to eat Thanatos?" ************* This takes place after Blood of Olympus, before The Hidden Oracle, and during Deathly Hallows. It is mostly in Harry's and Percy's point of view but a few others are thrown in. I worked really hard on this and I really hope you guys enjoy. The first couple of chapters are about 500 or so words but they get longer, I promise. If there are any spelling mistakes or grammar mistakes, feel free to comment them down below. It is an alternate ending to Deathly Hallows. Please don't kill me when you read the bonus chapter/ epilogue. In your demigodishness and all that, stay potterheads. Love you guys! Thanks for reading!

A hero who lost too many to save so much. Who has had the world rest on his shoulders again and again. Who will never give up till his final breath. Has disappeared. His name is Perseus Jackson and will he rise again? And will he be the hero or the villain? Percy Jackson/Avengers/Agents of SHIELD crossover.

When Percy, Annabeth, Nico, and Thalia get assigned a quest to protect Harry Potter, they never expected it to be back in time and in a whole different world: a world of magic. In Hogwarts, no one suspects a thing. But what happens when three young wizards find out the truth? Fandom time period: Takes place after the Blood of Olympus but during The Sorcerers Stone. DISCLAIMER: I own NOTHING. Characters, plot, ideas, and lines ALL belong to the wonderful authors Rick Riordan and Joanne Rowling. [Highest rank: 304 in fanfiction]

Perseus Jackson was a strange person, Harry decided. He came from overseas, had the weirdest American accent, spoke strange sayings, had ADHD and dyslexia, and stood up for every kid. He was a Gryffindor, but consorted with Hufflepuffs, Ravenclaws, and even Slytherins. Perseus Jackson was a weird person, Harry Potter decided. But he wouldn't have it any other way.

Percy Jackson is gone. Or rather, he was forgotten. It was like Hera's scheme all over again; but this time, he had no Annabeth to stay by his side, or Poseidon to call his father, or Camp Half-Blood to go home to. The world simply forgot about him. His powers had betrayed him, those who were once his comrades became his enemies, and his legacy was lost. So he decides to write a new one.

Voldemort is alive, and growing stronger. The Ministry are ignoring Dumbledore's warnings and are making him out to be an old fool to discredit him. The Order of Phoenix are trying their best, but they aren't certain themselves. Harry Potter is losing his cool....and Albus Dumbledore is contacting Percy Jackson. Dumbledore needs Percy...knows that Harry is the one destined to defeat Voldemort, but desperately needs help. So he asks Chiron, and Percy Jackson is sent to Hogwarts to protect Harry.

Betrayed. Forgotten. Five abandoned friends with nowhere to go, on the run from their parents who now wanted to kill them. Portrayed as liars and traitors, and forced to leave their home, what will become of the five innocent, young demigods?

A being born from the Five Rivers of the Underworld, stronger than most gods, Feared by many. Always hiding, always there. An immortal being that carries out the will of the Rivers. Stronger than a First-Born of a god. Much stronger. He is made of the Essence of the rivers. But he was not always like this. He was once a demigod, the most powerful demigod. He was respected by many and feared by his many enemies. But a hero's fate is always tragic. His fate was no different and he became someone else. He is now Raze, the Champion and Heart of the Rivers, a deity in his own right. But who was he? This ill fated hero? That was Perseus Jackson, Hero of Olympus. The greatest hero to walk the Earth. But fate is cruel. He is now Raze, the immortal bringer of Judgement. You can call him Raze, but only Raze. If you call him Percy, consider yourself lucky if he doesn't respond. Because much worse could happen to you. Much worse. He has changed a lot and it is their fault. They want him back? Too late.
