His character might become more cautious. Kakuzu is a cautious fighter, and Naruto could pick up this trait. He would be less likely to rush into battles without a proper plan.
Naruto's character could become more complex. He may start to question some of the values he learned in Konoha. With Yami's influence, he might be more inclined to take risks that he wouldn't have before.
Naruto's confidence may grow. Being trained by toads gives him new skills and knowledge, which makes him feel more capable in the face of challenges. He becomes more sure of himself and his abilities.
He becomes more patient. Kami's training likely involves a lot of self - reflection and inner - peace - seeking, which forces Naruto to slow down and think more before acting. This newfound patience helps him in both combat and his relationships with others.
Naruto's character might become more solitary. The training by Juubi could be intense and isolating, causing him to focus more on his own power and less on his friends. But at the same time, he might also develop a greater sense of responsibility towards the world as he realizes the power he now holds.
Naruto's character would become more disciplined. Vegeta is a strict trainer, so Naruto would have to follow a more rigid routine. This could make him less impulsive.
Naruto's character development under Onoki's training in fanfiction would be multi - faceted. Firstly, his patience would increase. Onoki is not one to tolerate rash behavior, so Naruto would have to learn to be patient. Secondly, his view of power would change. Instead of just relying on his brute strength and the Nine - Tails' chakra, he would start to appreciate the finesse and strategy that Onoki's earth - style jutsu represents. This would make him a more well - rounded ninja. He would also become more diplomatic, as Onoki would surely impart some of his wisdom about dealing with other villages and ninja. Overall, Naruto would transform from a head - strong young ninja into a more calculated and respected figure in the ninja world.
Naruto's character would likely become more patient. Yoda's training often requires a great deal of patience, which Naruto doesn't always have. So, he'd grow in that aspect. He might also become more in tune with his spiritual side, which could lead to him having a deeper understanding of his ninja way.
His character would become more mature. With the future Kurama's training, Naruto would face different challenges that force him to think and act more like an experienced ninja, rather than the impulsive one he used to be.
Naruto's character could become more empathetic. Hinata's kindness and understanding might help Naruto see things from different perspectives. For example, he might start to consider the feelings of his opponents more often during battles.
His confidence would soar. With Kyuubi's training, Naruto would realize his true potential and become more self - assured. He'd be less likely to doubt himself in battles.
