Naruto's character would experience a significant shift if trained by Deidara in fanfiction. His sense of strategy would likely be enhanced as Deidara is a master of planning his explosive attacks. He would become more calculating and less impulsive in battles. Additionally, Naruto's concept of power would expand. He would no longer solely rely on the Nine - Tails' chakra but also on the skills and knowledge imparted by Deidara. His relationships with his friends might also be affected. Some might be worried about the new, more dangerous Naruto, while others might see it as an opportunity for him to grow and become an even stronger protector of the village.
When trained by Deidara in fanfiction, Naruto's view of art could change. Deidara has a very distinct view of art as something that is transient and explosive. Naruto might start to see the beauty in destruction in a way, which could make his character a bit darker. His attitude towards his enemies might also change. Instead of always trying to redeem them, he might be more willing to use forceful and destructive means to defeat them, as he has learned from Deidara's combat approach.
When trained by Ibiki in fanfiction, Naruto's character would experience a significant transformation. He'd lose some of his naivete. Ibiki's world is full of deception and danger, and Naruto would have to adapt. He'd become more calculating, weighing the pros and cons of his actions more carefully. His sense of humor might also change, becoming more dry and sarcastic as he gets used to Ibiki's gruff personality. His relationships with his friends could be affected too, as he might seem more distant at first while he adjusts to his new mindset.
Naruto might become more reserved. Since Obito has a more brooding personality, Naruto could pick up on some of that. His once - bright and exuberant nature might be tempered.
Naruto's confidence might increase. With Cus's training, he could master new skills more quickly, which would boost his self - assurance in battles.
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.
The story would change a great deal. Naruto's power - up would be significant. He could face tougher enemies more easily. His friends might be both amazed and a bit worried about his new, more aggressive style. The overall tone of the story could shift towards a more action - packed and intense direction.
The training by death would likely toughen Naruto up both physically and mentally. He'd probably have a darker, more determined edge to his character. He might be more solitary in his training, spending more time alone to master the skills death has taught him. This could make him seem a bit more distant to his friends initially, but in the long run, it would make him a stronger and more reliable ally.
Naruto becomes more confident. After the time - skip and toad training, he knows he has the skills to face tough opponents. He's no longer the underdog who doubts himself all the time. His appearance might also change slightly to reflect his growth. Maybe he has a more serious look in his eyes. His sense of humor could still be there, but it's more refined, not as brash as before.
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.
