Suppose Naruto is in a team with Orochimaru (in a non - evil scenario for the sake of the fanfic) and Kabuto. Naruto would be constantly on edge as Orochimaru is unpredictable. He'd have to be more cautious and observant. His character would develop a sense of self - preservation that he didn't have before. With Kabuto, he'd learn about medical ninjutsu and intelligence gathering. This would make Naruto a more well - rounded shinobi, but also change his usually carefree and impulsive nature as he has to deal with two very different and complex personalities.
If Naruto was in a team with Sasuke and Sakura, but with different team dynamics. Maybe Sasuke is more open and friendly from the start. Naruto would develop a different kind of rivalry, more of a friendly competition. He'd also be more influenced by Sasuke's Uchiha techniques and might try to incorporate some of that into his own fighting style. His relationship with Sakura would also be less one - sided as they all work together more equally.
Sakura might become more independent. In her original team, she had certain roles and relationships that defined her. In a different team, she'd have to rely on herself more. For example, she might not have the same kind of support she had from her old teammates. This would force her to make decisions on her own and grow as a ninja.
At the start, Naruto would be deeply hurt and confused. His abandonment by Team 7 would be a major blow to his self - confidence. However, this could also be the catalyst for his growth. He would start to look inward and discover hidden strengths within himself. He might become more empathetic towards others who have been rejected or alone. His view of the ninja world would change, and he could become more of a lone wolf type of ninja. He would no longer rely on the teamwork that he once cherished, but instead find his own way to be strong. This new - found independence could lead him to make decisions that are more in line with his own beliefs rather than following the group.
His character could develop in several ways. First, he would become more independent. He'd be forced to make all decisions on his own, which could lead to him growing up faster. Second, he might become more solitary in nature. Since he doesn't have a team to bond with, he could focus more on his own goals and desires. However, this could also make him more empathetic towards others who are alone. Third, his ninja skills would likely improve at a different pace. Without teammates to spar with regularly, he might focus more on solo training techniques and develop unique skills that are tailored to his individual fighting style.
Their relationship would start off a bit rocky, considering Itachi's past actions. But as they work together, Naruto would start to understand Itachi's motives more. Itachi, in turn, would see Naruto's growth and potential. Eventually, they would develop a mutual respect for each other.
If his parents were strict disciplinarians from a traditional ninja clan, Naruto might be more reserved and less of a prankster. He'd be more focused on following the clan's rules and traditions, and his drive to become Hokage could be more about upholding the family's honor.
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 could develop a more solitary nature. Without the support system of Team 7, Naruto might become more self - reliant and withdrawn. He would have to figure out things on his own more often.
Naruto's personality could become more reserved. If he were in a class with more serious students, he might feel the need to tone down his exuberant self. He'd still be determined, but might show it in a more subdued way.
Suppose the teacher was from a different culture within the Naruto world. Naruto would be exposed to new values and ways of thinking. He might become more empathetic towards other cultures and incorporate elements of that culture into his ninja way. This could make him a more well - rounded and diplomatic shinobi in addition to being stronger in combat.
Naruto might become more cautious. Dealing with the 12 - tails, which is likely extremely powerful, would force him to think before acting. He can't just rush in like he sometimes does.
