Well, Naruto might be really confused at first. RWBY has a very different world setting compared to his own ninja world. He'd probably be intrigued by the unique characters and their powers in RWBY. For example, the use of Dust in RWBY might seem really strange to him as he's used to chakra-based abilities.
If Naruto reads RWBY fanfiction, he might get some new ideas for his own ninja techniques. He's always been open to new ways of fighting and improving himself. The diverse fighting styles in RWBY could inspire him to think about how he could incorporate some of those elements into his own combat. He could also be quite amused by the fanfiction's take on RWBY characters if it has a humorous slant.
They might be quite surprised. Minato, for example, could be shocked to see how some fanfictions might depict his relationship with his students or his family. Kakashi might find some of the stories about his past quite interesting, while Obito and Rin could have various reactions depending on how they are portrayed in the fanfiction.
They might be shocked by the different powers. For example, RWBY characters are used to their own semblances, and seeing Naruto's jutsus like the Rasengan would be quite a surprise.
She might be surprised at some of the creative interpretations of her son's story. For example, if there are fanfictions that explore different relationships for Naruto that she hadn't considered before, she could be taken aback.
They might be surprised by the complex and often dark themes in Warhammer fanfiction. RWBY characters are used to their own universe's rules and aesthetics, so the gritty and elaborate world of Warhammer could be a shock.
They might be amused. Some of the fanfiction could be really creative and different from the official storylines, so they could find it interesting to see how fans imagine their characters.
They might be shocked. In many cases, when a character like Jaune is betrayed in fanfiction, the RWBY characters could initially show disbelief as they've come to know him. It would disrupt their view of the group dynamic.
Well, they might be shocked. In the RWBY universe, the concept of betrayal is quite serious. If it's a Rose character being betrayed, the team could first show disbelief. They trust their comrades deeply, so this would be a huge blow to their morale.
The RWBY characters' reactions to RVB fanfiction could vary greatly. Ruby, with her love for stories, would likely be open - minded. She'd be eager to explore this new fictional world presented in the fanfiction. Weiss might initially scoff at it, thinking it's too different from the high - brow literature she's used to. But as she reads more, she might find some elements that she can appreciate. Blake could find herself relating to the complex relationships between the RVB characters, especially if there are themes of trust and betrayal. Yang would be the one shouting out her thoughts while reading, getting excited during the battles and making comments about how she would have done things differently.
One possible reaction is confusion. The future shown in the fanfiction could be so different from what they expect that they have trouble understanding it at first. Another reaction could be excitement. If the future seems full of great opportunities and adventures, they would be eager to experience it. And there's also a chance of disbelief. They might think that the future depicted is too far - fetched and not in line with their own beliefs about how things will unfold.
Well, they might be really confused at first. RWBY characters are from their own unique universe, and RussianBadger fanfiction likely has very different themes and settings. They could be intrigued by the new and strange concepts presented in the fanfiction.
