I think young Sasuke would have a very intense reaction. He was so consumed by his hatred for Itachi at that young age. A Sasuke vs Itachi fanfiction would be like a trigger for him. He would be eager to see how the fictional fight is portrayed. If Sasuke in the fanfiction is shown as strong, it might fuel his own ego and make him strive even harder to become powerful. However, if the fanfiction shows Itachi as superior, it could enrage him. He might feel that it undermines his own goal of defeating Itachi and he might even want to find the writer to correct their 'wrong' view.
Maka would also be a great character to interact with Mifune. As a strong - willed and intelligent student at the DWMA, she might be intrigued by Mifune's skills and his different approach to combat. She could try to learn from him, or even teach him some of the DWMA's ways in return.
I like Naruto in these fanfics because he always stays true to his beliefs. He is constantly trying to bring Sasuke back to the village and is willing to fight for their friendship.
One of the best moments is when they have a rematch that showcases their growth. Naruto has become stronger with his new jutsu, and Sasuke has further mastered his Sharingan powers. The intense battle of ideologies during the fight is captivating.
It really depends on the writer's preference. Some fanfictions might have Naruto winning because of his unwavering belief in friendship and his ability to draw on the power of the nine - tails. Others might have Sasuke winning due to his strategic mind and mastery of the sharingan.
It's not clearly stated in the original Naruto series that Konoha as a whole watches Naruto vs Sasuke fanfiction. Fanfiction is a creation of the fans outside the official story. However, it would be an interesting concept to think about. Some characters might be amused or even inspired if they were to read such fan - created stories, but there's no in - canon evidence for it.
One common theme is unrequited love. Sakura often has strong feelings for Sasuke, but Sasuke may be too focused on his own goals to fully reciprocate. Another theme is the power struggle. Since they are both powerful ninjas, their battles can represent a struggle for dominance or recognition within the ninja world.
One unique aspect is that it often explores Mifune's backstory. Since he has a somewhat mysterious past in the original Naruto series, fanfiction can fill in those gaps.
The combination of Naruto's ninja world and Mifune's samurai elements makes it unique. Naruto's world is filled with chakra and jutsu, while Mifune represents the traditional samurai values like honor and discipline. When these two worlds collide in a fanfic, it creates a new and exciting dynamic. For instance, in some fanfics, Mifune's swordsmanship is pitted against Naruto's ninjutsu, creating intense battle scenes.
