Naruto might be really entertained. He loves adventure and the fanfiction would be a new adventure for him. He could start imagining himself in the Bleach world, fighting Hollows or befriending Soul Reapers. He may also try to find similarities between his own story and the Bleach fanfiction, like how both have characters with strong wills and a desire to protect their friends and worlds.
He'd probably be shocked by the different power systems. Naruto is used to chakra and jutsus, while Bleach has spiritual energy and zanpakutos. So it would be a big change for him to read about.
Naruto's reaction would vary greatly. For stories that show his growth in new and interesting ways, he could be inspired. He might think about how he could apply some of the ideas in his real ninja training. But if there are fanfictions that are too far - fetched, he might scratch his head and wonder what the author was thinking. And if there are ones that play with his emotions in a way that's too intense, he might need some time to process it all.
She might be shocked. Rukia is used to the order and propriety of the Soul Society. Naruto's sudden request would be out of the blue for her. But she may also be intrigued by his boldness.
If the Avengers read Naruto fanfiction, different members would have different reactions. Bruce Banner might study the way the characters control their inner power, like how Naruto controls the Nine - Tails' chakra. Steve Rogers might be more focused on the moral lessons in the stories. He would look for similarities and differences between the values in the Naruto world and their own. Natasha Romanoff could appreciate the complex relationships between the characters, just like she values her relationships within the Avengers. And Clint Barton would probably enjoy the action - packed parts, imagining how he could use some of the ninja skills in his own battles.
He'd probably be very curious. Naruto has always been eager to learn about new things, and RWBY fanfiction would be a whole new world for him to explore.
Minato might be intrigued. He would be interested in seeing how the fans expand on Naruto's journey. Kushina would be delighted, seeing her son as the center of so many different tales.
They could be shocked. Some might not expect the wild ideas that fans come up with in fanfiction.
Kiba and Akamaru might find it really funny. They have a more light - hearted nature. They would enjoy reading about the different battles and situations the characters are put in, in the fanfiction. They might even get some inspiration for their own training or adventures from the wild ideas in the fanfiction.
Ruby would be all wide - eyed and full of enthusiasm. She'd be like a kid in a candy store, eager to share any cool ideas she found in the fanfiction with her team. For example, if there was a super - cool ninja weapon in the story, she'd start thinking about how Crescent Rose could be modified to have some of those features.
Rosario Vampire might be intrigued. It could be fascinated by the unique characters and abilities in Naruto's world.
Zeus, being the king, might be a bit dismissive at first. He's used to grandeur and the power plays in Greek mythology. But he could also be intrigued by the strong leadership shown by characters like Naruto. Athena would likely be very analytical, studying the problem - solving and battle strategies in the fanfiction. Ares, on the other hand, might be bored as he prefers more straightforward combat scenarios like in Greek battles.
