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 changes in multiple ways. Firstly, his determination is even stronger. The toad training hones his willpower. He becomes more self - reliant too. Before, he relied a lot on his friends in battles, but now he can hold his own better. Emotionally, he matures. He understands the consequences of his actions more deeply. For example, when he uses his new jutsu, he's aware of the potential damage it can cause, not just to the enemy but also to the surrounding environment. He also becomes more of a mentor figure. He can pass on the knowledge he gained from the toads to the younger ninjas in the village.
Well, in many such fanfictions, a key plot development is Naruto's enhanced combat skills. Since he's trained by toads, he might learn new jutsu like more powerful toad - related techniques. His relationship with the toads also deepens, and this could lead to him having a better understanding of the Sage Mode. Maybe he discovers new ways to combine his regular ninjutsu with the toad - based training. Another aspect could be his growth in terms of leadership. As he gets stronger, he might inspire other characters in the fanfiction to follow his lead more, which in turn could change the dynamics of battles or the overall story's progression.
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.
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.
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.
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.
Naruto's confidence might increase. With Cus's training, he could master new skills more quickly, which would boost his self - assurance in battles.
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 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 may become more calm and composed. Itachi's presence and training methods would likely instill a sense of discipline in Naruto. He'd probably be less impulsive in battles and think more before acting.
