If Naruto were trained by Aizen in a fanfic, it could lead to a significant change in his character. Aizen's influence could make Naruto more calculating and less impulsive. Naruto's view of the ninja world might also change as he starts to see the potential for power and control that Aizen represents. His relationships with his friends might be strained as he delves deeper into Aizen - like tactics. For example, he could start to keep secrets from them in the name of achieving greater power for the protection of the village.
In a fanfic where Naruto is trained by Aizen, Naruto would likely gain a whole new set of abilities. Aizen has the power of hypnosis and can manipulate the senses of others. Naruto could learn to use these powers in combat, perhaps to make his opponents see illusions of multiple clones or to make them misjudge his attacks. His training might also include learning about the nature of power and how to gain it without being noticed. This could make Naruto a more stealthy and dangerous opponent. His Rasengan, for instance, could be enhanced with Aizen - like illusions, making it even more unpredictable for his enemies.
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.
They might have a mentor - student relationship. Aizen, with his vast knowledge and power, would be in the position of a mentor, guiding Naruto. Naruto, being eager to learn and grow stronger, would be the student. However, there could be some tension as Naruto has his own sense of justice which might conflict with Aizen's more self - serving motives at times.
Naruto's powers would evolve in a very different way. Aizen's training might focus on the psychological aspect of combat. So, Naruto's chakra control could be enhanced in a way that allows him to project his presence in a more intimidating way, similar to how Aizen can make others feel his overwhelming power. His ninjutsu could also be modified to have hidden elements, like a Rasengan that has a secondary effect that only activates when the opponent least expects it, just as Aizen has multiple layers of deception in his attacks.
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.
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.
