There are plots where the characters from the Percy Jackson series are transported to a world dominated by Kung Fu. So, Percy, Annabeth, and the others have to quickly learn Kung Fu to survive and find their way back home. In some fanfictions, the gods themselves are interested in Kung Fu and Percy is sent on a quest related to it, like finding a sacred Kung Fu weapon or learning a secret Kung Fu form that could save the world of the gods.
One common plot is Percy learning Kung Fu to enhance his combat skills. Maybe he goes to a hidden Kung Fu school in the demigod world. Another plot could be a crossover where Percy teams up with a Kung Fu master from a different mythology to fight a common enemy. For example, he might work with a Shaolin monk.
One great Percy Jackson and Kung Fu Panda fanfiction is 'The Quest of Po and Percy'. It combines the mythological elements of Percy Jackson's world with the martial arts and humor of Kung Fu Panda. In this story, Percy and Po team up to face a common enemy that threatens both their worlds.

One popular trope is the 'fish out of water' story. For example, Percy being in the Kung Fu Panda world not understanding all the martial arts and cultural norms there. Or Po in the world of demigods, confused about the Greek mythology stuff.

A common theme is the power transfer. Usually, the dragon imparts some sort of special kung fu power or knowledge to a human. For example, it could be a secret fighting style.
One common plot is Percy being framed by his friends for a crime he didn't commit. This often leads to him being hunted by other demigods or facing exile. Another is his friends siding with his enemies for power or personal gain, leaving Percy alone to fight against the odds.
Often, you'll see plots where Percy discovers his Gryffindor heritage in a really unexpected way. Maybe he has a vision or finds an old artifact that links him to Gryffindor. Then there are plots where he forms new friendships at Hogwarts. Since he's used to being a demigod, his relationships with wizards and witches can be really different. He might also get involved in Hogwarts house rivalries in a unique way because of his Gryffindor connection. There are also plots where Percy has to use his water - related powers in the context of the Hogwarts magic, which can be really cool to read about.
One common theme is the crossover of different fighting styles. Kung Fu from Kung Fu Panda and Ninjutsu from Naruto are often compared and combined in these fanfictions.
A common theme is self - discovery. Since Tigress is a complex character, many fanfictions explore her journey to understand herself better, like her emotions and her place in the world of kung fu.
One frequent theme is cross - cultural exchange. Since Naruto is from a ninja - based world and kung fu has its own cultural roots. In these fanfictions, Naruto may interact with different cultures that practice kung fu, leading to exchanges of ideas, values, and techniques. It also often includes the theme of power - up. Learning kung fu gives Naruto an extra edge, and he uses this new power to face greater challenges and protect his friends and village.
