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.
The character dynamics would be greatly affected. Thor's bow could be seen as a catalyst for a whole new era of cooperation between the two mythologies. Percy would have to step up and be a diplomat of sorts, representing the Greek side. This would put him in a difficult position as he has to balance the expectations of his own people and the new relationship with Thor. Thor, on the other hand, might face some backlash from his own kind for bowing to an outsider. But this could also lead to a stronger bond between them as they face these challenges together.
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.
Since fanfiction is often shared on various platforms, it could be anyone from a dedicated Percy Jackson or Aquaman fan. It could be a young writer who loves both universes and decided to combine them in this interesting scenario. There are so many people writing fanfiction these days that it could even be someone who just had a creative burst one day and decided to pen this story.
In the fanfiction, once Loki bows, it could set off a chain of events. Percy might gain a certain status or power boost because of Loki's submission. This could make him a target for other villains or jealous characters. Meanwhile, Loki might be seen as a traitor by some of his own kind. The plot could then revolve around Percy and Loki trying to deal with these new situations, with Percy having to protect Loki from those who want to harm him for his actions, and Loki having to prove his new - found loyalty to Percy.
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.
I really like the fanfic 'When Thor Meets Percy'. In this one, the author focuses on the cultural shock between Thor, who is used to the grandeur of Asgard, and Percy, who is more in tune with the laid - back yet dangerous world of demigods. Their interactions are hilarious as they try to understand each other's powers and the different rules of their respective mythologies.
Probably not. Thor is busy with his own heroic deeds in Asgard and dealing with his Norse - related challenges. While Percy Jackson fanfiction is about a different set of characters in a different mythological world. There's no connection between them in the original works, so it's hard to imagine Thor taking the time to read Percy Jackson fanfiction.
One great 'Percy Jackson and Thor Fanfiction' is 'The Godly Alliance'. It combines the worlds really well. The author does a great job of bringing Percy's powers and Thor's hammer into the same story. It's full of action and adventure.
