Well, Naruto could develop some unique combat styles. Since Gai is all about the power of youth and his own special brand of fighting, Naruto might blend his existing ninja skills with Gai's teachings. For example, he could combine his shadow clone jutsu with Gai - style taijutsu moves. This would make him a more versatile fighter in the fanfic. Also, Gai's strict training regime would likely toughen Naruto up even more, both physically and mentally.
In a fanfic where Naruto is trained by Gai, Naruto's growth would be significant. Gai is known for his Spartan - like training methods. Naruto, who is already determined, would be pushed to his limits. His chakra control might improve as he learns to use his body more efficiently through Gai's training. He could also gain a new perspective on friendship and teamwork, as Gai values his relationship with Lee and others highly. Moreover, Naruto might start to see the value in hard - core physical training, which could enhance his overall ninja capabilities.
He would probably become extremely strong in Taijutsu. Gai's training is intense and focuses a lot on physical strength and speed. Naruto might also pick up Gai's positive and energetic attitude towards training and life in general.
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.
If Naruto were trained by Whis in a fanfic, it could lead to some really interesting crossovers. Naruto's ninja skills combined with Whis' training could make him a force to be reckoned with. He might even develop some new forms or abilities that are a blend of the Naruto and Dragon Ball universes. For example, he could use his chakra in ways similar to how the Dragon Ball characters use ki, but with his own ninja - style twist.
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 a fanfic where Naruto is trained by the Shinigami, Naruto would face a whole new set of challenges. The training would be tough as the Shinigami's methods are likely to be very different from what he has experienced before. He might have to endure tests that involve facing his inner demons or dealing with the power of death directly. This could lead to a significant character development for Naruto. He would not only become stronger physically but also mentally, as he grapples with the complex concepts associated with the Shinigami's realm.
In a fanfic where Naruto is trained by Madara, Naruto might gain some extremely powerful and unique jutsu. Madara is a very skilled and experienced shinobi. He could teach Naruto some ancient and forbidden techniques that are not known in the regular Naruto world. This could make Naruto an even more formidable opponent, perhaps with a new style of combat that combines his own natural abilities with Madara's dark and powerful knowledge.
If Naruto is trained by Kyuubi in a fanfic, it would change a lot of things. Firstly, Naruto's relationship with the Kyuubi would shift from a more adversarial one (initially) to a mentor - student relationship. Kyuubi could train Naruto to use its chakra more efficiently, which would enhance Naruto's physical abilities like speed, strength, and endurance. Naruto might also gain a deeper understanding of the nature of chakra itself. Kyuubi could pass on some of its ancient knowledge about the ninja world, and this could help Naruto in his quest to protect the village and his friends. Moreover, Naruto's standing in the ninja world would rise even more as he becomes more powerful under Kyuubi's tutelage.
Well, Naruto would probably become extremely powerful. Kami has great power and knowledge. With Kami's training, Naruto might learn some really unique and powerful jutsus. His understanding of chakra could reach a whole new level.
Well, Naruto being trained by the Shinigami in a fanfic would be a wild ride. Naruto's character would likely change a bit. He'd be exposed to the Shinigami's rather dark and mysterious world. This could make him more solemn at times. In terms of his abilities, he could gain the power to temporarily 'borrow' the strength of deceased ninjas. He might also develop a new kind of Rasengan that has a spiritual component, something that can not only damage the body but also affect the soul of his enemies.
