Shikamaru would be lazy about it at first. He might think it's a waste of time. But once he starts reading, he'd get drawn in by the interesting plot twists. He'd then start to analyze how the fanfiction changes the existing dynamics between the characters and might come up with his own theories about how the story could continue.
Sakura would be a bit more critical. She would check if the fanfiction portrays her accurately in terms of her strength and her relationships. If it doesn't, she might be tempted to write a comment correcting the author. But if it does, she would be flattered.
Naruto would be thrilled. He loves attention and the idea that people are writing stories about him would make him feel really special. He might even try to find the authors and befriend them.
They could be shocked. Some might not expect the wild ideas that fans come up with in 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.
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.
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.
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.
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.
Naruto would likely be excited yet a bit scared. He'd be eager to make the future a better place but also worried about the bad things he might see. Sasuke would probably be more reserved, analyzing the future information carefully. Hinata would be shy about it but also determined to protect those she loves if she saw any danger in the future for them.
If Naruto was an Ajin in a fanfiction, the characters in Naruto would have a mix of reactions. Hinata would be concerned for Naruto's well - being. She might be a bit scared at first because of his new and strange abilities, but still stand by him. The villagers, who have had a rocky relationship with Naruto in the past, might be afraid of him all over again. They could see his Ajin powers as a threat. On the other hand, Naruto's close friends like Shikamaru would try to understand what's going on and help Naruto control his powers if they can.
He may be surprised. Fanfictions can have some really out - there ideas that he might not have considered before. For instance, a fanfiction might have Naruto suddenly having a new, super - powerful jutsu that was never seen in the original series.
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.
