The plot could also involve Thor being curious about the demigod world. He might have heard tales of Percy's adventures and wants to meet him to learn more about how demigods operate, their powers, and their training. It could be a kind of cultural exchange between the Norse and Greek mythological worlds.
Perhaps there's a prophecy that only Thor and Percy together can fulfill. This could bring them together in an epic adventure. They would have to learn to work together, despite their different backgrounds and powers. Percy's ability to control water and Thor's power over lightning could be combined in some cool ways to fight against the forces of evil in the story.
Fanfiction.net is also a good place to look. There are many Percy Jackson fanfics, and although it might take some searching through the different categories and using relevant keywords like 'Thor' and 'meet', you could come across what you're looking for.
They might start with some mutual suspicion. Percy would be cautious around Thor as he's a very powerful being from a different mythology. Thor might see Percy as a bit of an oddity at first. But then they could start to exchange stories about their adventures. Percy could tell Thor about his battles with the Titans, and Thor could share his tales of fighting giants. This would lead to a newfound respect between them.
Well, in such a fanfic, there could be epic battles. The Avengers with their superpowers like Iron Man's high - tech suits and Thor's lightning, and Percy Jackson with his water - controlling abilities. Maybe they would team up against a common enemy, like some ancient and powerful monster that threatens both the world of the Avengers and Percy's demigod realm.
It could mean that Thor, in this fictional scenario, is really into the world and characters of Percy Jackson as depicted in the fanfic. Maybe he admires Percy's heroic deeds and the unique mythology in the Percy Jackson series.
Perhaps in the fanfic, Percy is a weapon in the sense that he is the key to activating a super - powerful ancient weapon. The gods and goddesses are all vying for control over him because they know that with Percy, they can wield this ultimate weapon. Percy has to navigate through political intrigue among the deities while also trying to figure out his own role in this whole mess.
The plot could be that Percy discovers an old sweatshirt in his attic that turns out to be a magical artifact from one of the gods. Maybe it gives him the power to control water in a new and unique way, and he has to figure out how to use it without getting into trouble with the other gods.
One possibility could be a story where the worlds of Norse mythology (represented by Thor) and Greek mythology (Percy Jackson's world) collide. Maybe there's a threat that only their combined powers can defeat. Thor bows as a sign of respect for Percy's skills and heroism in this new, combined adventure.
One possible plot could be that Percy discovers he has a hidden Norse heritage that makes him the heir of Thor. He then has to learn about Norse mythology and how to control Thor's powers, all while still dealing with his Greek demigod life. For example, he might have to face off against Greek monsters using Thor's hammer, which could cause some confusion and interesting battles.
In this fanfic, Percy could be driven to revenge because of a personal loss caused by the Olympians. He might start by infiltrating Olympus under a false identity. Once inside, he begins to subtly undermine the gods' authority. He could spread rumors among the minor gods and spirits, causing unrest in the divine realm. As the chaos builds, Percy's revenge plot unfolds, leading to a big showdown between him and the Olympians.
A great plot could involve Percy being a character in a magical world. He's been on a long and dangerous adventure and has finally returned home. All he desires is to cuddle with his family or his beloved pet. The fanfic could then focus on the tender moments of their reunion, with lots of hugs and cuddles, and Percy finally feeling safe and loved in their embrace.
