One possibility is that Ryu trains Naruto in the ways of self - discipline and inner strength. Since Ryu is known for his strong will in the Street Fighter universe. Naruto, under his guidance, might learn to better handle his emotions during tough battles. This could lead to Naruto becoming even more powerful as he doesn't let anger or over - confidence cloud his judgment. And they could go on adventures together, facing enemies that require both Naruto's ninja skills and Ryu's martial arts expertise.
One possible plot could be Naruto learning Zabuza's unique water jutsu techniques. For example, he might master the Hidden Mist Jutsu which Zabuza was famous for. This would give Naruto an edge in combat, especially in stealthy attacks.
One possible plot could be that Naruto, under Killer Bee's training, quickly masters new forms of his Rasengan. Since Killer Bee is a master of the Tailed Beast Bomb, he might teach Naruto how to better control and combine the power of his Nine - Tailed Fox chakra with his existing jutsu.
One possible plot twist could be that Tsunade trains Naruto not just in physical combat like she did with others, but also in medical ninjutsu. This would be unexpected as Naruto is more known for his brute force. Maybe Naruto uses his new medical skills in a creative way during a battle, like healing his opponents to show mercy and then defeating them when they are off - guard.
A plot twist could be that Slade has an ulterior motive for training Naruto. Maybe he plans to use Naruto as a weapon against Konoha in the future. He might be secretly feeding information about the village's defenses to an enemy while training Naruto. So, when Naruto discovers this, he has to find a way to stop Slade and also deal with the fact that he has been unknowingly part of a scheme against his own home.
One possible plot twist could be that Mikoto discovers Naruto has a hidden kekkei genkai that she helps him unlock. This new power could completely change Naruto's abilities and how he's perceived in the ninja world.
In this fanfic, there could be a lot of character development for Naruto. Genma's training might not only be about physical skills but also about mental strength. Genma could share his own experiences in the ninja world, which would help Naruto understand the importance of strategy and patience. This could lead to Naruto becoming more of a well - rounded ninja, able to handle different situations more effectively than before.
One possible plot twist could be that Sakumo's training methods are very unorthodox compared to what Naruto is used to in the village. For example, he might focus more on stealth and assassination skills which Naruto initially struggles with as he is more used to head - on combat. Another twist could be that Sakumo has a hidden agenda for training Naruto, like he is preparing Naruto for a specific threat that he foresees but hasn't shared with the village yet.
Well, in this fanfic, perhaps Naruto is sent to the Hidden Mist for some sort of exchange program. There, Mangetsu takes him under his wing. Mangetsu might train Naruto not only in combat skills but also in stealth and strategy. Naruto, with his already strong will and determination, quickly adapts to Mangetsu's teachings and starts to combine his own Uzumaki - like chakra control with the water - style jutsu he learns, becoming a more versatile ninja.
Perhaps in this fanfic, Kosuke trains Naruto not just in physical combat but also in the mental aspects of being a ninja. He might teach Naruto how to handle difficult situations, make strategic decisions, and overcome his inner demons. This could lead to Naruto becoming a more well - rounded and powerful ninja.
The fanfic could involve Asura taking Naruto to some secret places for training. There, Naruto might discover hidden aspects of his own heritage. He could also meet other powerful beings related to Asura. Asura could train Naruto to master his emotions better, which is crucial in the ninja world. This training would help Naruto make more rational decisions during high - stress situations like in the middle of a war or when facing a powerful enemy who tries to manipulate his feelings.
