It has a certain level of popularity. Since both RWBY and Naruto have their own unique elements, the idea of Jaune Arc in a Naruto - inspired fanfiction allows for a lot of creativity. Writers can play with concepts like Jaune having a Sharingan or using ninjutsu. This type of fanfiction can attract readers who are looking for something new and different in the fanfiction world.
Well, some characters might be shocked. For example, Deku would probably be very concerned about how he's portrayed in the fanfiction. He might be a bit embarrassed if it shows his more vulnerable moments during the War Arc. Bakugo, on the other hand, could be angry if the fanfiction doesn't show his strength accurately. He's all about being seen as powerful, so any misrepresentation might tick him off.
One interesting Naruto arc fanfiction could be about an alternate ending to the Pain arc. Maybe Naruto finds a different way to convince Pain without using brute force. Another could be a fanfiction set during the Chunin Exams arc, where a minor character gets more spotlight and changes the course of the exams in a unique way. There are also fanfictions that explore what would happen if Naruto was raised by different people during his early life in the Hidden Leaf Village arc.
The first story arc of Naruto concludes approximately at episode 21. It's marked by the resolution of certain key events and the advancement of the overall plot. However, the exact determination can be subjective based on individual interpretations.
War Machine's story arc in Avengers 2 mainly focuses on his participation in the fight against Ultron. He uses his suit's capabilities to take on the enemy.
In a Naruto fanfiction, Jaune Arc could start his own ninja clan. He could use his knowledge from RWBY to create a new style of combat that combines aura and chakra. Maybe he falls in love with a kunoichi and has to deal with the cultural differences between his world and the Naruto world while also facing off against powerful villains who want to steal his new - found ninja techniques.
It could be a rogue ninja who has mastered the art of embodiment in a dark way. He might be able to steal the powers or abilities of others by embodying them.
Naruto is definitely one of the most popular characters. Since he is the main protagonist in the original arc, he often takes center stage in fanfiction too. His growth, his new jutsu, and his interactions with Pain are frequently explored. Another popular character is Pain himself. His complex motives and powerful abilities make him an interesting subject. Writers often try to humanize him more in fanfiction.
