Percy Jackson was a hero, yes. But he was also a boy who had lost to much. Harry Potter is the Boy Who Lived, yes. But he is getting cocky with his fame. What happens when these boys meet? With their different cultures, different views, and different pasts. I present to you: The Greatest Heros. I DO NOT OWN HOO OR HP ALL RIGHTS GO TO RICK AND JK I ONLY OWN THE PLOT!

Voldemort has risen, and Dumbledore tells Harry, Ron and Hermione about a group of mysterious half-muggles who are willing to help. Harry reads Percy Jackson and the Lightning Thief with a few others-what will their reactions be when they read the book? As their knowledge builds up, the wizards prepare to meet the demigods.

Nico di Angelo leads a quest to find Tom Riddle, who has defied Hades and cheated death twice. With Percy and Annabeth, he'll find and destroy seven horcruxes and navigate through Hogwarts. Between a budding romance with Will Solace and a burning desire to make his father proud, he is going to do whatever it takes to outwit the Fates and succeed... or die trying. COMPLETED

When Dumbledore finds out that Voldemort has a grandson, he and few other members of the Order, including Harry Potter go to Manhattan to bring him to Hogwarts. Will this child and Harry be best friends or worst enemies?

The Gods of Olympus messed up big time. With a wrong opinion and incomplete facts, they believe none other than Draco Malfoy needs protection from Harry Potter. They send a few demigods over to Hogwarts to help out. However, how happy will these demigods be with this new quest? And although the gods were wrong about many things, does Draco end up needing protection after all?

After the war, Percy Jackson is prepared for a normal, peaceful life. However, he is thrown into the middle of a war between wizards and finds out more about his family. Percy Jackson is Voldemort's grandson.

Anybody related to Voldemort must be inherently evil... right? Harry Potter thinks so. Nobody good could come from Voldemort. When Dumbledore announces that Voldemort has a grandson named Percy Jackson, Harry's already labeled Percy as EVIL and put him on his enemy list. But Percy Jackson is not whats expected by a long shot and he's not going to take any prejudices lying down...

All Percy Jackson wanted was a little peace. His old friends Irony and Mayhem have other plans when it is discovered that he might just have more than one evil grandfather. Because, really, one never seems to be enough. HP/PJ crossover. Set during OotP and after TLO.
