Who could be the main character in the 'one man team naruto fanfiction'?

It could be a rogue ninja from a rival village. This ninja has a personal vendetta against Konoha and specifically targets Team 10 because of Naruto's presence. He might be jealous of Naruto's growing power and fame and wants to prove himself by defeating the team.

In such fanfiction, Naruto's self - reliance grows. He becomes more confident in his abilities as he doesn't have a team to fall back on. For instance, he may start making his own battle strategies without consulting others, leading to more creative and risky approaches in combat.

Perhaps an old enemy of one of the members of Team 9 shows up. Since Naruto has joined the team, they might see it as an opportunity to get revenge. This antagonist could be someone who was once defeated by the member's family and now wants to prove themselves. They would be very cunning and use their knowledge of the team member's past to try and divide the team.

It could be Danzo. He's always been a bit of a shadowy figure in the Naruto series. Maybe he sees Naruto as a threat to his power and influence in the village and manipulates the situation so that Team 7 has to abandon him. He would be a great main antagonist as he has the resources and the motives to cause such a rift in Team 7.

It could be Orochimaru. He has always been interested in Sasuke and might target ANBU Team 7 to get to him. Orochimaru's experiments and his desire for power make him a formidable and menacing villain. He could also be using some new jutsu or have created more powerful minions to fight against Team 7.

Well, it could be about a single character in the Naruto universe forming their own team for various reasons. Maybe they don't fit in with the normal teams or they have a unique mission that requires them to work alone but still be considered a 'team' in a sense. For example, they might be on a solo espionage mission where they have to rely only on themselves like a one - man team.

Well, in such a fanfic, Naruto could be shown as a lone wolf. His character might be more solitary, focusing only on his own goals. He may not rely on the support of his friends like Sasuke or Sakura. He might develop his own unique fighting style that doesn't require teamwork. His relationships with others could also be different, perhaps more distant as he's so used to being on his own in this fictional scenario.

Mega Man Zero could also be the main character if the story focuses on his adventure in the Naruto world. He would be the outsider, having to learn about chakra, ninja clans, and the political structure of the Naruto world. His combat skills and sense of justice would play a big role in how he navigates this new and strange world.

Kurenai might be a good sensei for Naruto's different team. Her expertise in genjutsu would be valuable. She could help the team develop their skills in this area, especially if the new team members have some potential in genjutsu. Kurenai is also very perceptive, which would be great for guiding Naruto and his new teammates through difficult situations.

Perhaps a forward - thinking businessman. He might be the one who sees the potential in new technologies and invests heavily in them. He then uses his business acumen to spread these technologies across the fictional land, making him the catalyst for the industrial revolution. For example, he could be the first to mass - produce a new type of machinery, which then becomes the cornerstone of many industries.
