When trained by Gai in the fanfic, Naruto's character would experience a profound transformation. Firstly, his sense of determination would be sharpened. Gai's unwavering belief in the power of hard work and the 'power of youth' would fuel Naruto's already existing determination. He would be more tenacious in achieving his goals. Secondly, Naruto would become more of a team player. Gai emphasizes the importance of comradeship and working together. Naruto, who already values his friends, would further understand the significance of relying on others and being reliable for them. His overall personality would become more balanced, with his brashness being tempered by Gai's teachings of self - discipline and respect for others.
He might become more disciplined. Gai's training is very structured, so Naruto would have to follow a strict routine, which could make him more organized in his approach to things.
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.
Naruto's morality could be somewhat skewed. Orochimaru has a very different view on right and wrong compared to Naruto. So, Naruto might start to question some of his previous beliefs. For example, he might be more willing to use dangerous or forbidden jutsus if it means achieving his goals. He'd also probably be more distrustful of others, as Orochimaru always has ulterior motives. This would be a big change from the Naruto who was always so quick to trust and befriend people.
If trained by DIO, Naruto's character would likely change in several ways. Firstly, he might become more self - centered. DIO is all about self - preservation and power, and some of that could rub off on Naruto. However, he would still have his core values. His sense of justice might get distorted a bit as DIO's methods are often amoral. But on the positive side, he could become more confident and fearless in the face of stronger opponents, as DIO's training would surely toughen him up both physically and mentally.
Naruto's character would likely become more complex. On one hand, he would have the raw power and new skills from Tremor's training. But on the other hand, he might struggle with the more aggressive and perhaps morally ambiguous aspects of Tremor's fighting style. He might question his own values at times, but ultimately, he could emerge as a more well - rounded ninja. For example, he might initially be hesitant to use some of the more destructive techniques Tremor teaches him, but as he realizes the necessity in certain situations, he would grow in his understanding of the grey areas in combat and ninja life.
Naruto might become more brooding. The dark training from Darkseid could make him less of the cheerful, optimistic Naruto we know. He may be more secretive about his new powers and training.
Naruto might become more calculating. Urahara is a very strategic person, and under his training, Naruto could start thinking more before acting. For example, instead of just rushing into a fight, he'd analyze the situation first.
Naruto would likely become more serious. Madara's influence would probably make him less impulsive. For instance, he would think twice before charging into battle without a proper plan.
Naruto would likely become more stealthy. Itachi is known for his stealth and if he trains Naruto, Naruto would pick up some of those skills. He might start to rely less on his brash and straightforward fighting style and incorporate more subtlety.
Naruto's fighting style would likely become more stealth - oriented. Since Obito is known for his ability to move undetected, he might teach Naruto some techniques to blend into the shadows and surprise his opponents. For example, Naruto could learn to use the environment to his advantage in a more subtle way, rather than his usual straightforward attacks.
Naruto's fighting style would likely become more refined. With Sakumo's training, he might start using more precise jutsu instead of his usual brute - force attacks. He could also incorporate more strategic movements, like better use of the terrain and stealth.
