In a fanfiction where Naruto is on a team by himself, his character would experience significant growth. He would start to view the world from a different perspective. Without the camaraderie of a team, he would look for other sources of motivation. His confidence could take a hit initially as he is used to having comrades. But as he overcomes challenges alone, his self - confidence would be rebuilt in a different way. He might also become more creative in his battle strategies as he doesn't have the same set of skills from teammates to fall back on. This would force him to think outside the box and develop his own unique combat approaches.
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.
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 a negative way. He may lose his trust in people easily.
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 Without the support system of Team 7, Naruto might become more self - reliant and withdrawn.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.
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.
His character would become more physically - centered. Naruto would focus more on his body's strength and speed. He'd be constantly pushed by Guy's extreme training methods. His confidence would also grow in a different way. Instead of relying on his ninjutsu and the Nine - Tails' power as much, he'd trust his own physical abilities more. For example, in a fight, he might choose to engage in hand - to - hand combat first rather than immediately summoning clones or using rasengan.
The plot could take a dark turn. Naruto's friends might become worried about him and try to stop his self - experimentation. This could lead to a conflict between Naruto's desire for power and his friends' concern for his well - being.
The story could start with Naruto being in a strange place and suddenly seeing his other self. Then they would start to exchange words. It might develop into a battle at first as Naruto tries to figure out if this other self is a threat.
In such fanfiction, Naruto's self - reliance grows. He becomes more confident in his abilities as he doesn't have a team to fall back on. For instance, he may start making his own battle strategies without consulting others, leading to more creative and risky approaches in combat.
Naruto and Shikamaru would have an interesting relationship. Shikamaru might find Naruto's impulsiveness annoying at first but would later learn to appreciate his determination. Naruto, on the other hand, would respect Shikamaru's intelligence and might try to learn some strategic thinking from him. With Choji, Naruto would bond over food very quickly. They could have eating contests and in the process, become really good friends. As for Ino, Naruto would probably have a bit of a rocky start. Ino might see Naruto as a bit of a nuisance, but as they go on missions together, she would see his good heart and they would become friends too.
Naruto's character would likely become more stoic. Vergil is known for his calm and collected demeanor, so Naruto might start to suppress his more exuberant emotions. He could become more calculating in battles, thinking several steps ahead like Vergil does when facing his enemies.
