In this kind of fanfic, Naruto's character development would be significant. Initially, he'd be full of anger and resentment towards Sarutobi and Konoha. But as he faces the challenges of the outside world, he realizes that there are bigger issues at play. His experience outside the village would make him more empathetic towards those who are also ostracized. He'd become a more well - rounded character, not just a loud - mouthed ninja from Konoha. His relationships with others would change too. He'd form deeper bonds with those who accept him during his exile, and these relationships would shape his future actions and decisions. He might also start to question the whole ninja system, which could lead to him trying to change it when he has the chance to return to Konoha.
Naruto would likely be more confident. With Sarutobi as his adopted father, he would have a strong support system. He might not be as brash as in the original story, as Sarutobi's teachings would instill more discipline in him.
Naruto would become more disciplined. Sarutobi is a strict teacher, so Naruto would have to follow rules more closely. This would make him less impulsive in battle.
Naruto's jutsu repertoire would be different. Hiruzen could teach him some of his own signature jutsu or long - forgotten techniques. This would make Naruto stand out even more in combat. He might also be better at taijutsu as Hiruzen could have trained him in more traditional and refined forms of hand - to - hand combat. His overall combat style would be more refined and less reliant on brute force. This new - found finesse in combat would earn him more respect from his peers and opponents alike.
In a 'Naruto banished by Sarutobi' fanfic, the plot might revolve around political intrigue within the village. There could be a group that convinces Sarutobi to banish Naruto for their own gains. Naruto, being banished, would likely set out on a journey of self - discovery. He'd meet new allies and foes. He might even discover new powers or lineages that were hidden from him while he was in the village. And all the while, he'd be thinking about getting back to Konoha to clear his name.
His character would develop in a major way. Banishment is a huge blow, and in the Avatar world, he'd face new challenges. He might start as a lost soul, but as he meets new people and discovers bending - like abilities, he'd grow in confidence. He'd also become more empathetic as he experiences different forms of discrimination and power struggles in the Avatar world, and this would shape him into a more mature ninja when he eventually returns to Konoha.
Naruto would likely be more conflicted. Instead of his usual cheerful self, he'd constantly struggle with the idea of being associated with 'evil'. He might be more withdrawn at first, not sure how to handle this new identity.
Naruto's character could develop in many ways. Firstly, he would be less impulsive as he has his parents to guide him. He might also become more understanding of the village's politics since his parents could explain things to him. His self - esteem would improve, and he would be more at ease with his status as a jinchuriki. His relationships with others in the village would also change, as people would see him in a new light with his parents' support.
Naruto's character would likely become more independent. Without his parents, he'd have to rely on himself. He might become more cautious too, as he's been betrayed by his own family. His view of the world could change from being naive to more cynical at first. But as he meets new people and has new experiences, he may regain some of his positive outlook, while still maintaining a new - found sense of self - reliance.
Naruto's character could develop a more jaded side. After being banished, he might start to question the values he once held dear. However, his underlying kindness still remains. He becomes more cautious and calculating with his new power, not wanting to be used again.
Naruto's view of family would be different. Instead of longing for a family like in the original story, he would have a real family with Sarutobi. This would change his motivation. Instead of wanting to be Hokage to gain recognition, he might want to be Hokage to continue Sarutobi's legacy and protect the family he now has in the village.
