There could be. Given the creativity within the RWBY fan community, many unique interpretations of characters are explored in fanfics. Jaune Arc being a monk in a fanfic isn't too far - fetched. However, I'm not sure if there's a well - known or widely - read one specifically. You might have to dig around in the RWBY fanfic sections of various websites.
Jaune would likely become more self - reliant. Without the support of his friends and family, he'd have to learn to take care of himself. He might become more cautious in trusting others, having been betrayed by those closest to him.
One great RWBY Musician Jaune fanfic is 'Jaune the Melodic Huntsman'. In this fanfic, Jaune discovers his musical talent and uses it in a unique way during battles. It's really interesting as it combines his newfound musical abilities with his growth as a huntsman.
A unique take on Jaune's character as a female. For example, how she might interact differently with the other characters in Beacon Academy. Maybe she has a different fighting style or a distinct personality trait that sets her apart from the male Jaune in the original series.
One common theme is self - discovery. Jaune often finds himself in new and unfamiliar situations in crossover fanfics, which forces him to learn more about himself. Another theme is friendship. As he interacts with characters from different universes, he forms new bonds.
Growth is a common theme. After the chaos at Beacon, Jaune often has to grow up quickly, both in terms of his combat abilities and his mental strength.
One common theme might be growth. Jaune is a character who has a lot of room to develop in the RWBY series, so in fanfics, his growth as a fighter or as a person could be a theme. Another could be friendship, as he forms bonds with the other characters in RWBY.
The plot is crucial. It could be something like a new adventure that the female Jaune embarks on, perhaps in a different realm or with a different set of goals. For instance, she might be on a quest to save her family or prove herself in a male - dominated world. The plot should keep the readers hooked from start to finish.
A RWBY fanfic where Jaune has a system can be really interesting. It often gives him unique abilities or ways to progress that are different from the original series. For example, the system might provide him with stat boosts or special skills that he can use in combat. This can lead to new and exciting storylines, like him facing stronger enemies earlier or having to figure out how to use his new powers in creative ways.
