The main characters could also include some of the antagonists or anti - heroes in the Naruto universe. Maybe a reformed criminal or a ninja from a rival village who wants to learn from Naruto. This would add an interesting dynamic as Naruto has to not only teach them but also deal with the potential mistrust from the village.
In addition to Naruto and his students, some of the other senseis from the village could also be important characters. They might offer advice to Naruto on how to handle his students, or they could be involved in joint training sessions. Kakashi, for example, could pop in from time to time to share his wisdom with Naruto based on his own experience as a sensei.
Obviously, Naruto himself would be one of the main characters as he is the sensei. His students could be a group of new genin. For instance, the children of his old friends like Boruto and Sarada could be among his students.
It's possible that a group of students could be the main characters. They all learn from the genius sensei in different ways. One student might be great at physical combat, another at ninjutsu, and they have to work together under the sensei's guidance. Their combined growth and how they interact with each other and the sensei can form the core of the 'naruto genius sensei fanfic'.
Obviously, Koro Sensei would be the central character. His unique appearance and abilities would add a lot of fun elements to the story. The students from Class 3 - E like Nagisa, Karma, and Kayano could also be main characters. They could interact with Koro Sensei in various ways related to the lemon theme, like using lemons in their assassination attempts in a very comical and harmless way.
Naruto is often paired with Ebisu Sensei in fanfiction. Since Ebisu was assigned to train Naruto at one point, many fanfictions build on that relationship, showing how Naruto grows under his tutelage and how Ebisu has to adapt to Naruto's unorthodox ways.
The main characters are Naruto and Anko Sensei. Naruto brings his optimism, his will to protect the village, and his ever - expanding list of ninja techniques. Anko Sensei, on the other hand, contributes her knowledge of the ninja world, her combat skills, and her unique personality. Their interactions, whether it's sparring, having conversations, or facing challenges together, form the core of the fanfiction.
Well, the main characters usually start with Naruto. Then there are his students. They might be a diverse group. There could be a foreign exchange student from another ninja village, who has different abilities and a different view of the ninja world. Hinata could be involved too, maybe as Naruto's wife in the fanfiction and she helps him with the emotional side of teaching, like dealing with homesick students. And there could be a mischievous student who constantly challenges Naruto's patience and teaching skills.
In the fanfiction, Naruto's new sensei could be a mysterious figure who has ties to the Sage of Six Paths. This person might have been waiting for the right time to appear and train Naruto. They could possess knowledge about the origin of chakra and how to fully unlock Naruto's power. It could also be someone who was once an enemy but has now changed their ways and wants to use their skills to train Naruto for the greater good of the ninja world.
There's a chance that Naruto's new sensei could be a self - taught ninja who has developed their own unorthodox style. This person sees Naruto's ability to think outside the box and wants to refine that in him. They could introduce Naruto to a new way of looking at chakra control and combat strategies that are completely different from what he has been taught so far.
Well, it could be the children of his friends. For instance, Boruto could be one of his students, and Naruto could use his own father - son relationship with Boruto as a teaching tool, sharing stories of his own father to inspire Boruto. Another student could be Sarada, Sasuke's daughter. Naruto could teach her some of the skills he learned from Jiraiya, passing on that knowledge.
Tenten would also be an interesting choice. She could focus on weapon - based combat training for Team 7. Since she has extensive knowledge of all kinds of weapons, she could introduce new and unique weapon techniques to the team.
Well, the plot might involve Kushina seeing Naruto's potential right from the start and training him intensively. She could also share her own experiences of growing up as an Uzumaki, which could help Naruto better understand his heritage. And perhaps they go on special missions together where Kushina guides Naruto not just in combat but also in making tough decisions. There could be a lot of emotional moments as Kushina fills the role of both a sensei and a mother - like figure to Naruto. Also, Kushina could introduce Naruto to other Uzumaki - related things like ancient seals or special chakra control techniques that were unique to their clan.
