Another way to do this crossover is to have a prophecy that links Percy and Thor. The prophecy could say that only by the combined might of the son of Poseidon and the God of Thunder can a great evil be stopped. This evil could be a new kind of monster that has the ability to absorb both Greek and Norse magic. Percy and Thor would have to overcome their differences quickly. They would travel to different realms, both Greek and Norse, to gather items or allies needed to defeat this monster. Along the way, they would face many challenges and grow to respect each other.
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.
Percy's water - based powers could interact interestingly with Thor's lightning. For example, water is a great conductor, so if Thor were to strike Percy's water constructs, it could create a powerful blast. Or Percy could use his control over water to create a shield against Thor's lightning, diffusing it in a spectacular show of power.
One plot idea could be that Percy Jackson discovers a magical artifact that somehow links his world to the Marvel Universe. Thor senses the power of this artifact and comes to investigate, leading to a meeting with Percy. Meanwhile, the Avengers also get wind of it and think it could be a threat. So, they all end up in a big showdown where they have to figure out if they're on the same side or not.
In this type of fanfiction, the power levels would be really interesting to explore. Naruto has his chakra and all his powerful jutsu like the Rasengan. Sasuke has his Sharingan and his own array of attacks. When compared to the powers of the demigods in Percy Jackson's world, such as controlling water like Percy or having super strength like some of the other demigods, there could be some epic battles and team - ups. They could also learn from each other. For example, the demigods could teach Naruto and Sasuke about Greek mythology, while Naruto and Sasuke could show them some cool ninja techniques.
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.
In most Percy Jackson canon, there is no relation to Thor. However, in fanfiction, anything can be possible. It could be that the author has created a unique crossover where Percy Jackson has some connection to being the heir of Thor, perhaps through some magical or divine intervention that the fanfic writer has dreamed up.
There could be Annabeth. She is Percy's close friend and often plays a crucial role in Percy's adventures. In a situation where Thor kneels to Percy, she might be there to witness it and offer her own thoughts or reactions.
One possible reason could be that Percy has shown some extraordinary power that even Thor, a powerful god, respects. Maybe Percy has defeated a common enemy in a really remarkable way that makes Thor recognize his strength and kneel in admiration.
Another plot could be that there is a prophecy in the Percy Jackson world that can only be fulfilled with the help of the Thor Corps. So Percy has to convince them to join him on a quest. This would involve a journey through different mythological realms, facing various challenges, and building relationships between the two groups of characters.
One idea could be that Percy and his friends find themselves in the Star Wars universe. Maybe they land on a planet that's rich in water, like Naboo. Percy could use his water - controlling abilities to help the locals against some kind of threat, like the Trade Federation. Meanwhile, the Jedi could sense the different kind of power Percy has and be both intrigued and cautious.
