If Naruto was trained by Hashirama in a fanfic, he would probably become even stronger. Hashirama was a master of many combat techniques. Naruto could pick up some of Hashirama's unique fighting stances and strategies. Maybe he would learn how to better control his massive chakra reserves in more efficient ways. This training could also give Naruto a deeper understanding of the history of the ninja world. He might discover secrets about the origin of chakra and the first shinobi villages that could help him in his future battles and diplomatic efforts.
Well, Naruto would probably become extremely powerful. Hashirama was a very strong ninja with unique abilities like his Wood Style. Under his training, Naruto could learn new jutsu and gain a deeper understanding of chakra control. He might also inherit some of Hashirama's wisdom and leadership skills, which would be beneficial for Naruto in his journey to protect the village.
In this kind of fanfiction, Naruto might learn some unique jutsu from Hashirama. For example, he could master the Wood Style more quickly and effectively. Maybe Hashirama would teach Naruto how to better control chakra for large - scale jutsu, which would make Naruto even more powerful in battles against strong enemies.
In a fanfiction where Naruto is trained by Hashirama and Madara, he would likely become an extremely powerful ninja very quickly. Hashirama's wood - style jutsu and his ability to control tailed beasts could be passed on, and Madara's combat skills and Sharingan - related techniques might also be taught. Naruto could combine his own Uzumaki chakra reserves with these new skills and become nearly unbeatable.
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.
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.
