If Naruto is trained by Hinata in a fanfic, it could be really interesting. Hinata has a deep understanding of the Hyuga clan's techniques and traditions. She could share this knowledge with Naruto. Maybe he would learn how to better sense and anticipate his opponents' moves, just like the Byakugan allows. And on a more personal level, their relationship could grow stronger as they spend more time together during the training sessions, which might also affect how Naruto views himself and his role in the village.
In such a fanfic, Naruto might become more in tune with his emotions. Hinata is known for her calm and perceptive nature. She could teach Naruto how to better control his chakra in a more gentle and patient way compared to some of his other teachers. This could lead to Naruto developing new and unique jutsu that combine his natural exuberance with Hinata's precision.
In this fanfiction, Naruto and Hinata might gain unique powers. Since they are trained by the Kyuubi, they could potentially learn to control and utilize the Kyuubi's chakra in new ways. Naruto already has a connection with the Kyuubi, so this training could enhance that bond further. Hinata, on the other hand, might develop more confidence and stronger combat skills, making her a more formidable ninja.
In a fanfiction where Naruto and Hinata are trained by Kami, there are numerous possibilities. For Naruto, he could receive insights on how to achieve a new level of Sage Mode or even something beyond. Hinata, on the other hand, may be shown secrets about the Hyuga clan that were long forgotten. They would both grow in strength and character. Their relationship might also evolve in a different way as they support each other during this intense training. This training by Kami would likely put them in a position to face much stronger foes in the future of the fanfiction.
In this fanfiction scenario, Naruto and Hinata would likely gain extraordinary powers. Kaguya has immense and unique abilities. Naruto might learn new forms of chakra control or even some ancient jutsu that Kaguya knew. Hinata could improve her Byakugan skills to a whole new level, perhaps even being able to see things on a different plane of existence. They might also gain a deeper understanding of the origin of chakra and the history of the ninja world from Kaguya directly.
In this kind of fanfiction scenario, Naruto and Hinata would likely gain extremely powerful abilities. Naruto already has a connection to Hagoromo through his Sage of Six Paths powers. With direct training, he could master new jutsu and control his power more precisely. Hinata, on the other hand, would be able to enhance her Byakugan skills and maybe even develop new techniques related to the Otsutsuki power that Hagoromo possessed. They could also gain a deeper understanding of the ninja world's history and the true nature of chakra, which would make them even more formidable in battles and in protecting the Hidden Leaf Village.
In fanfiction, if Naruto and Hinata were trained by Kurama, they would likely become extremely powerful. Naruto already has a connection with Kurama, and with Hinata by his side, Kurama could teach them new jutsu and ways to better control their chakra. Maybe they would develop unique combat styles that combine Naruto's brute force and Hinata's elegance, making them an unbeatable duo in the ninja world.
Well, Naruto might become extremely powerful in terms of his mental manipulation skills. Aizen is known for his cunning and ability to deceive. Naruto could learn new ways to outwit his opponents. He might also gain some unique combat techniques that are more psychological in nature, rather than just relying on his physical strength and ninjutsu.
If Naruto were trained by Toriko in a fanfic, it would be an interesting blend of two different worlds. Toriko's training might introduce Naruto to a whole new concept of the 'food chain' in terms of power. Naruto could learn how to incorporate the energy from different foods into his jutsu. Moreover, the cultural differences between the ninja world and Toriko's world would create some really fun and unique interactions. Naruto might be shocked at first by Toriko's appetite but then learn to respect and utilize the power that comes with it for his own growth as a ninja.
Well, Naruto might gain some really cool new combat skills. Vergil is a very skilled fighter, so he could teach Naruto some advanced sword techniques or unique ways of using chakra in combat. Maybe Naruto would also pick up on Vergil's more strategic and calculating approach to battles.
In such a fanfic, Naruto might gain unique abilities. Cell is a powerful and complex character from Dragon Ball. If he trained Naruto, Naruto could potentially learn new combat techniques, perhaps even something related to Cell's perfect form's regeneration ability. This would make Naruto an even more formidable ninja in the Naruto universe.
Well, in a fanfic where Naruto is trained by Tremor, Naruto could end up with a whole new set of jutsu. Tremor's influence might lead Naruto to combine his existing Rasengan technique with earth - based chakra manipulation. This could result in a Rasengan that not only has the spinning force but also causes massive tremors upon impact, making it a much more devastating attack. Also, Naruto might learn to sense opponents' movements through the vibrations in the ground, giving him an edge in combat.
