In such a fanfic, Naruto's character would develop in a rather interesting way. Initially, he'd be extremely frustrated and angry at the people who have caused him so much distress. But as he distances himself, he could turn to nature and solitude for solace. He might start to communicate with animals and understand the natural world better. This new connection could give him a different perspective on life. He would then return to the village, not as the overly - eager Naruto, but as a wiser and more balanced individual, ready to make changes in the village based on his newfound understanding of himself and the world around him.
Naruto would likely become more studious. Instead of just relying on his natural energy and willpower, he'd have to spend time in labs and studying books. His impulsiveness might decrease as he learns the importance of precision in scientific work.
His character would be shaped by the need for self - preservation. He may learn to hide his emotions better. Maybe he would become more perceptive of people's true intentions. He would grow to be more cautious in his interactions. Over time, as he endures the abuse, he could start to question the world around him and why people are so cruel. This internal struggle could lead to a more complex and mature Naruto, who still retains his core values of friendship and hope.
Naruto's character would likely become more reserved and stealthy. He'd be used to operating in the shadows, which is a big change from his normally boisterous self. His sense of justice might also be refined, as the ANBU has a different view on protecting the village.
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 might become more of an isolationist. Danzo was not one to form close bonds easily. So Naruto could be more reserved and keep to himself. However, his natural urge for connection might still be there, and he'd struggle between his upbringing and his true nature. He could start off as a loner but gradually learn to open up as he experiences different things in the village and realizes that not all relationships are like the ones Danzo had.
His character could develop in a darker direction. The torture and manipulation from Orochimaru's experiments could make him question his values. However, it could also strengthen his resolve to protect his friends and the village. He may start to see the world in a more complex way, understanding that there are greater evils out there. And his newfound powers from the experiments could give him a sense of responsibility that he didn't have before.
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.
He would probably be more calm and composed. Kurenai's influence might make him better at handling his emotions.
Naruto's character would develop a different sense of loyalty. Instead of being loyal to Konoha, he'd be loyal to Kumo. His goals would change too. Maybe instead of aiming to be Hokage, he'd aim to be one of the top - ranking ninjas in Kumo. His social skills could also be different. Kumo has a different social environment, so he might be more rough around the edges in his interactions.
Naruto's character could become more calculating. Since Jango is a more cold - calculated fighter, Naruto might start to think more before acting. He could become less impulsive in battles.
