Well, one idea for this crossover could be that Savitar somehow ends up in the world of Percy Jackson. Maybe he's chasing after some new kind of speed - the speed of a demigod? And Percy has to figure out how to deal with this strange, super - fast being who doesn't seem to follow the normal rules of the Greek myth world.
A great start for a Percy Jackson and Savitar crossover fanfiction could be that Savitar is lured to the Percy Jackson universe because he senses a great power there. This power could be related to the gods or the magical items in the Percy Jackson world. Once there, he teams up with some of the minor villains in the Percy Jackson series, like the Laistrygonians. Percy and his friends then have to not only deal with their normal foes but also this new, super - fast adversary who has teamed up with their enemies. This would create a whole new level of challenges for Percy and his friends, and also open up opportunities for new friendships and alliances within the story.
In this fanfiction concept, imagine Savitar being from a different dimension and accidentally stumbling into the Percy Jackson universe. He doesn't understand the rules at first. The demigods are initially scared of him because of his speed and strange powers. But Annabeth, being the smart one, figures out a way to communicate with him. Through their interactions, Savitar starts to question his own motives and actions, leading to a character arc where he may even end up helping the demigods against a greater threat.
Another idea is that Sophie Foster from KotLC travels to the Percy Jackson universe. She could be mistaken for a demigod at first. She would have to learn about the Greek gods and monsters. Her telepathic abilities would be really useful in the Percy Jackson world. For example, she could communicate with some of the monsters to find out their plans. And Percy and his friends would help her understand this new and dangerous world.
I really like 'Percy in the Marvel Universe'. In this fanfiction, Percy gets transported to the Marvel universe. He has to figure out how to get back home while also dealing with all the superheroes and villains there. It shows his character development as he tries to adapt to this new and very different world. The story also has some interesting pair - ups, like Percy and Spider - Man becoming friends and having adventures together.
One great Percy Jackson and Immortal crossover fanfiction is 'The Immortal Demigod'. In this story, Percy discovers he has an immortal side due to some ancient magic. It's full of action and interesting character interactions. The author does a great job of blending the two worlds together.
Another one to check out is 'Justice League meets Camp Half - Blood'. In this fanfic, the Justice League discovers Camp Half - Blood. It's cool to see how Batman would interact with Chiron, or how Wonder Woman would view the demigod powers. There are a lot of great character moments as the two very different universes collide.
One great Percy Jackson crossover fanfiction is the one where he crosses over with the Harry Potter universe. It's exciting to see how the magic of the two worlds interact and how Percy and Harry might team up. Another good one is the crossover with the Avengers. Imagining Percy fighting alongside superheroes like Thor and Captain America is really cool.
One idea could be that Naruto, with his powerful chakra and skills, is somehow transported to the world of Percy Jackson. He might be mistaken for a demigod because of his extraordinary abilities. Naruto could then team up with Percy to fight against a common enemy, like an ancient monster that threatens both their worlds.
One way could be to have Percy Jackson's powers of being a demigod interact with the superpowers of the Avengers. For example, his ability to control water could be used in a joint mission with Thor's lightning powers. Maybe they are facing a common enemy that can only be defeated by combining their unique skills.
One idea could be a crossover with the Harry Potter universe. Percy could visit Hogwarts and have to deal with both magical and mythological threats. Maybe he'd team up with Harry to defeat a common enemy that combines dark magic and ancient Greek monsters.
One great Percy Jackson crossover fanfiction is 'Percy Jackson in the Marvel Universe'. It combines the world of Greek mythology from Percy Jackson with the superheroes of the Marvel world in an exciting way. The author does a great job of integrating Percy's powers and his demigod status into the Marvel setting, creating interesting new storylines and character interactions.
