Yes, there are likely fanfictions out there where Jaune is somehow related to the Naruto universe. Fanfiction writers often like to cross over different fictional worlds and characters.
Well, Jaune in RWBY fanfiction can vary a lot. Sometimes he's the underdog who overcomes huge challenges, and other times he might have unique powers or a special backstory.
His character could become more self - assured. Jedi are known for their confidence in their abilities, and Jaune might gain that as he masters Jedi - like powers.
Well, not literally everyone. While Jaune fanfiction might have a large following, there are plenty of people who may not be interested in it at all. Some might be into different shows or types of fanfiction, and some might not be into fanfiction in general.
It could be because Jaune is a relatable character. He starts off as a bit of an underdog in RWBY. So, fans like to write stories where the other characters notice his potential and become obsessed with him as he grows.
Perhaps there are antagonists in the form of other players. These could be characters who are overly competitive or have some sort of grudge against Jaune. Their actions and decisions during the games would drive the conflict and keep the story moving forward.
Maybe there are other magical creatures. Like a friendly sprite that befriends Jaune and helps him understand the more delicate aspects of the magical world that the dragon might not be so good at explaining. There could also be an evil sorcerer who wants to capture Jaune because of his unique connection to the dragon, thinking he can use it for his own dark purposes.
One idea could be that Ruby and Jaune are partnered for a special mission outside of Beacon. Ruby's speed and combat skills combined with Jaune's strategic thinking could make them a great team. For example, they might be sent to investigate a mysterious Grimm activity in a far - off village. Ruby can quickly scout the area with her speed, while Jaune plans their approach based on the information she gathers.
One possible secret could be about his family heritage. Maybe in the fanfiction, Jaune has a hidden connection to a powerful family in the RWBY universe that he's kept under wraps for some reason, like to avoid unwanted attention or because of some family feud.
I'm not sure specifically about 'jaune and raven pregnant' fanfiction. But generally, in the world of fanfiction, any scenario is possible. Writers might use this as a way to explore new aspects of the characters, such as their growth, their relationships with other characters in a changed context. It could also be a way to introduce new plot twists and emotional arcs in the fan - created stories.
