What are some interesting plot ideas for a Harry Potter x Percy Jackson fanfic?

One idea could be that the wizarding world discovers the existence of demigods. Harry and his friends team up with Percy and his crew to fight a common enemy that threatens both their worlds, like an ancient, powerful dark force that feeds on magic and the power of the gods. For example, a new kind of dark wizard who has made a pact with a minor, evil god.

A plot could involve a competition between the two groups. Maybe the wizards challenge the demigods to a series of magical and physical tasks. This would lead to some really interesting interactions as they learn about each other's abilities. The demigods would be amazed by the wizard's spells and the wizards would be in awe of the demigods' powers.

A really interesting plot could be that there is a tournament where demigods and shinobi compete. Naruto and Percy are the representatives of their respective groups. Along the way, they learn about each other's cultures and powers. They also discover that there are some dark forces trying to manipulate the tournament for their own evil purposes. So, they have to put aside their differences and work together to expose and defeat these forces.

A unique plot idea could be that the Greek gods and the wizarding world's magic are actually two sides of the same coin. So, Percy and Harry have to figure out how to use both types of magic to defeat an ancient evil that is trying to destroy both realms. Another one is a plot where the demigods are being hunted in the wizarding world because they are seen as a threat to the balance of magic.

One idea could be that they discover their family connection during a magical crisis. Maybe a dark force is threatening both the wizarding world and the world of the Greek gods, and their combined powers as cousins help in the fight. For example, Harry's knowledge of complex spells and Percy's control over water could be used in creative ways to defeat the enemy.

A plot where the villains from both universes team up. Voldemort and the Titans or Giants could join forces. This would force Percy and Harry to put aside their differences and work together. They would need to combine their unique powers and knowledge. Percy's ability to control water and his combat skills along with Harry's magic skills and knowledge of the wizarding world's secrets would be crucial in fighting this powerful alliance.

Well, they could be the result of some sort of cross - over experiment gone wrong (but in a good fanfic way). Maybe they have powers from both worlds but struggle to control them at first. For example, they might accidentally cast spells while trying to use their demigod powers. And they could be the bridge between the two groups of friends. The demigods are skeptical of wizards and vice versa, but the twins help them understand each other.

One idea could be that Harry and Percy meet during a magical convergence. They realize they can combine their powers to fight a new, powerful dark force that threatens both the wizarding world and the world of the Greek gods. For example, Percy could use his water powers to put out a magical fire created by a dark wizard, while Harry uses his magic to protect Percy from a monster attack.

One idea could be that the twins have powers from both the wizarding world and the demigod world. They can use magic spells like in Harry Potter and also have the abilities of a demigod from Percy Jackson. For example, they can control water like Percy and at the same time cast defensive spells. Another plot could be that they are sent on a mission to stop a threat that endangers both the wizarding world and the Camp Half - Blood. They have to use their combined knowledge and skills to succeed.

One idea could be that the demigods and wizards have to team up to fight a common enemy that is threatening both the magical and the mythological worlds. For example, a dark force that can manipulate both magic and the powers of the gods. Another plot could involve Percy and his friends getting lost in the wizarding world and having to navigate Hogwarts while also dealing with their own demigod issues. Maybe they discover that some of the magic in the wizarding world has its roots in the ancient Greek magic that the demigods are familiar with.
