Some characters might be amused. For example, Ichigo might find it interesting to see how fans imagine his adventures in different ways. He could chuckle at some of the more out - there scenarios.
Some characters might be shocked. For example, if a heroic character sees a fanfiction where they turn evil in the future, they would be very surprised. They might start to question their own actions and whether there are any signs that could lead to such a change.
They would probably be shocked. For example, Naruto might be amazed to see how the village develops further. He could be excited to see new generations of ninjas and the peace that his efforts have led to in the future. Sasuke might be more reserved in his reaction, but he would also be interested in seeing if his own actions had a long - term impact on the ninja world.
Some characters might be shocked. For example, Naruto himself. He has always been full of hope for the future and worked hard to build a better world. If he saw a future that was not as positive as he expected, he would be very disappointed at first. But then he would surely try to find a way to change it, because that's his nature.
Well, some characters might try to change the future they read. For example, Ichigo might see a future where his friends are in danger and immediately start training harder to prevent it. He's always been the type to take action.
They might be shocked. For example, Ruby could be amazed by how her skills develop in the future depicted in the fanfiction. She might see herself using new techniques and facing different challenges, which would make her eager to train more to reach that level.
Sasuke could have a really unexpected reaction. If the fanfiction portrays a future where he and Naruto have a very different relationship than he expected, he could be completely thrown off. He might start to question his own actions and decisions. Also, Tsunade's reaction could be quite a shocker. If the fanfiction has her in a situation where she has to give up her position as Hokage in a way she didn't anticipate, she might get really angry at first but then start to consider the implications for the future of the village.
The X - Men might have mixed reactions. Professor Xavier would likely be intrigued by the potential for better mutant - human relations in the future. However, Wolverine might be skeptical and on guard, fearing that the future holds new threats to mutants. He's always been the more cynical of the group. The different reactions among the Marvel characters would add a lot of depth and interesting plot points to the fanfiction.
Some characters might be amused. They could find the creative interpretations in the fanfiction interesting, especially if it gives a new spin on their relationships or adventures in the Batman universe.
Some might be amused. For example, characters like Nagito Komaeda could find the different interpretations of himself in fanfiction either interesting or in line with his self - deprecating view. He might chuckle at how fans perceive his luck cycle in strange new ways.
