The 'fish - out - of - water' trope is also seen a lot. When Percy ends up in Thor's world or vice versa, they are both out of their element. Percy has to deal with the strange Norse landscapes and customs, while Thor might struggle with the modern - day world if he goes to Percy's. It creates a lot of comical and interesting situations in the fanfiction.
The popularity of Thor Percy Jackson fanfiction lies in the unique combination of two different mythologies. People are drawn to seeing how the Norse and Greek mythologies interact. For instance, Thor's hammer in the world of Percy Jackson's demigods is a really exciting concept to explore.
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.
The 'Power - up' trope is also quite common. Fans like to write about Percy getting new powers or strengthening his existing ones. It gives a sense of growth and development. There's also the 'Alternate Universe' trope, where the story is set in a completely different world from the original Percy Jackson universe, like a modern - day high school setting but with the demigod elements.
Another common trope is the 'alternate universe' or AU. This could be something like a modern - day retelling of the stories in a different setting, or even a world where the characters have different powers or relationships. In Percy Jackson fanfiction, you might see an AU where Percy is a regular kid without knowing his demigod heritage at first. In Shadowhunters fanfiction, it could be an AU where the Clave has different rules.
One popular trope is memory recovery. In many of these fanfics, Percy has to gradually remember his past life as a demigod. It adds an element of mystery and character exploration as he figures out who he was. Another is the 'fish out of water' situation. Since he's reincarnated, he often has to adapt to a new world or time period, which can lead to some really interesting and comical situations.
One common trope is the 'fish out of water' situation. For example, Percy suddenly finding himself in Hellboy's world and having to adapt to the much darker and grittier environment. Another trope is the 'team - up against a greater evil'. This usually involves Percy and Hellboy combining their unique skills to take on a powerful villain that threatens both their worlds.
One popular trope is the 'fish - out - of - water' scenario. For example, Percy might find himself in the world of Danmachi and have to adapt to its different rules and cultures. Another common trope is the power - up trope. Characters from Percy Jackson's world might gain new abilities in the Danmachi setting or vice versa.
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.
