A fanfiction plot could start with Percy having strange dreams about Thor. These dreams lead him to discover that he is the heir of Thor. As he delves deeper into this new identity, he finds that there is a dark force that is trying to prevent him from fully claiming his inheritance. This force is causing chaos in both the Greek and Norse mythological worlds. Percy has to race against time, using his wits, his friends from both mythologies, and the powers he gradually unlocks as Thor's heir to stop this evil and restore balance. He might also have to deal with internal conflicts as he tries to reconcile his two very different heritages.
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 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.
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 Percy discovering his connection to Hufflepuff while on a quest. Maybe he stumbles upon an ancient artifact that reveals his heritage. He then has to balance his duties in the Percy Jackson world with his new - found identity in the Harry Potter world, and deal with the reactions of both his demigod friends and the Hogwarts students.
A plot could involve Percy being sent to retrieve Thor's hammer as a favor to the Norse gods. He'd have to face many challenges on his way to the hammer, like battling Norse monsters that are guarding it. Once he gets there, he might find that the hammer has a mind of its own and tests Percy to see if he's worthy. This could be a great way to show Percy's growth as a character, as he'd have to rely on his wits and not just his powers. And in the end, he might either return the hammer or keep it for a while to use against a greater threat in the Percy Jackson universe.
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.
One possible plot could be that Percy and Thor meet during a battle against a common enemy that threatens both the Greek and Norse realms. They initially clash due to their different fighting styles and personalities. Percy, with his water powers and quick thinking, and Thor, with his mighty hammer and thunder powers. But as they face challenges together, they start to respect each other's abilities. They learn from one another, like Percy teaching Thor about the subtleties of water combat in certain terrains, and Thor showing Percy how to better use his strength in a more brute - force kind of way. Eventually, they become friends and vow to protect both their worlds from future threats.
One possible plot could be that Voldemort's heir somehow discovers a way to cross into the Percy Jackson universe. They might target the demigods because they see them as a source of power, perhaps thinking that the demigods' connection to the gods could be harnessed for their own dark magic. Percy and his friends would then have to figure out who this new threat is and how to stop them.
It could also lead to an interesting crossover in the fan community. Fans of both Thor and Percy Jackson might start creating their own fanfiction that combines the two universes. This could bring more creativity and excitement to the fanfiction world. Moreover, Thor's fangirling could attract more attention to Percy Jackson fanfiction, increasing its popularity.
Well, it could be about Percy Jackson being chosen by Thor to be his champion. Maybe Percy has to go on quests that are related to Thor's realm, like dealing with frost giants or retrieving some powerful Asgardian artifact. He might use his water - controlling abilities in new and interesting ways in the context of Norse mythology.
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.
