A new life form has arrived on Remnant. Clever and resourceful, this life form could prove to be deadlier than the threat of Grimm. But will it be able to adapt to its new habitat?

The Giant war is over and Percy Jackson is spent. Finally there's a chance he can be with Annabeth for a while and he eagerly awaits the summer they have planned together. But when Hecate shows up and sends Percy on a new quest, it could be the by far stupidest thing he has ever done. He must be the new teacher at Hogwarts. Harry Potter has been attacked by the Ministry and Dementors. If that wasn't enough he now has a new teacher. But he is like, a 17 year-old kid. Who looks a lot like him. It's Harry's 5th year and he is now a nutter to the wizarding world. So when he sees the kid show up at Number 12 Grimmauld Place, he starts thinking he might actually be mental. The new kid turns out to be a teacher. The teacher of DADA. But Umbridge is still there- as the High Inquisitor. It seems she watches the new teacher-Professor Jackson- a lot more than the others. Something is off about him. And the Golden Trio always tries to find out what.

"He saw a almost identical boy a few feet away from him. The only difference was that he had a small scar shaped like a lightning bolt on his forehead a glasses. Percy walked closer to him, realizing that he noticed him too" If you're a Potterhead AND a PJO/HOO fangirl/boy then this book is for you! Read to find out what happens next.... The character Percy Jackson and the other demigods are owned by Rick Riordan and The character Harry Potter and the other wizards are owned by J.K Rowling, thus other characters belong to the author of this book/me! The dragon belongs to the amazing artist viria and I only did a little change to Percy's mouth to make him smile.

The order of the Phoenix asks the demigods in America for help to defeat Voldemort. Now Nico, Thalia, and Percy are going to Hogwarts to avoid being thrown into another war. Will they be friends or enemies with the golden trio? Will they be able to avoid the war or will they be at the center of it? And for which side will they fight? Disclaimer: I don't own Percy Jackson or Harry Potter. All rights go to Rick Riordan and J.K. Rowling. Except the plot. The plot is mine.

After the war with Gaia, the seven, Reyna, Calypso, Nico and Thalia are sent on a quest to Great Britain, to go to Hogwarts, a School of Witchcraft and Wizardary in Britain to learn the ways of the forgotten wizarding world. On their quest, they will make friends and enemies amongst the students at Hogwarts. However, one question remains above all others. Will they be able to make an alliance between the two worlds, or will a raging war erupt between them? DISCLAIMER: I DO NOT OWN ANY OF THE CHARACTERS IN THIS STORY, I ONLY OWN THE PLOT! THE PJO/HOO CHARACTERS BELONG TO RICK RIORDAN AND THE HP CHARACTERS BELONG TO J.K. ROWLING! ALL RIGHTS GO TO THEM!

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?

Y/N L/N was an ordinary son, well ordinary on the surface. He was skilled in parkour, weapons, as well as stealth. But when his fathers store is robbed he will be forced to attend a school he wants nothing to do with. After all how's an assassin supposed to work with eyes watching him at all times I DO NOT OWN ASSASSIN'S CREED, OR RWBY. THEY BELONG TO THERE RESPECTIVE OWNERS

When an extremely overpowered monster meets the forces of heaven and hell, chaos is sure to begin! I own nothing

(Y/N) (L/N) is just an ordinary school going boy, atleast that's what he thinks. He is the wielder of a Sacred Gear that is supposed to be extremely powerful, to the point where it can beat Ophis and The Great Red even at their prime, combined. This Sacred Gear houses the Dragon God of Creation and Destruction, Xaimur. Xaimur's name was never mentioned in the List of the 10 Strongest Beings as he didn't want to show of his power. Legend has it that Xaimur was so strong, so strong, that he could destroy or create alternate realities using just a mere thought. He is the twin brother of Ophis. It was believed that the Universe was created when Xaimur and Ophis started feeling lonely, and felt the need of the existence of other beings. Read the story as (Y/N) starts to uncover more and more about about his past, while learning about his fate and the power that resides within him. *I do not own any of the characters in this story except the fictitious character and Xaimur.
