Naruto would probably become more confident in some ways but also more vulnerable in others. The symbiote's powers could boost his confidence in battle, but at the same time, he would be vulnerable to the symbiote's possible betrayal or its negative effects on his body. His relationships with his friends would also change. Some might be afraid of him when they find out about the symbiote, while others might try to help him control it. All these factors would contribute to a significant evolution of his character in the fanfiction.
Naruto's character would likely become more complex. With the symbiote, he might start to question his own identity. Is he still just Naruto Uzumaki, or is he now something more? He could become more cautious as he has to deal with the new power and the potential risks it brings. For example, if the symbiote has a negative influence on his emotions, he would have to learn to control that.
He might develop a more solitary side. Since he has to keep the symbiote a secret at first, he would distance himself from his friends. This could make him more introspective. Also, the symbiote could give him access to knowledge or memories that are not his own. This could expand his understanding of the world and different forms of power, which in turn would change his approach to being a ninja. He could start to think more about the big picture rather than just focusing on becoming Hokage.
If Naruto gains a symbiote suit in fanfiction, his character development would be multi - faceted. He would initially be excited about the new power, but soon realize the challenges that come with it. His relationships with his friends could be affected. Some might be worried about the change in him, while others might encourage him to master the symbiote's power. He would have to learn self - control and discipline in a whole new way. His journey would involve not only mastering the physical abilities of the symbiote suit but also maintaining his positive and determined personality. He'd need to find a balance between using the symbiote's power for good and not succumbing to its possible negative influences, which would be a great test of his character and growth.
Initially, the relationship could be rocky. Naruto, being used to his own way of life, might find it difficult to adjust to the presence of the fem symbiote. However, as the symbiote reveals its powers and shows that it can help Naruto in his struggle against neglect, they begin to form a connection. The symbiote may start to feel empathy for Naruto's situation, and Naruto may come to see the symbiote as a partner. As they face more and more difficulties together, such as fighting against those who still look down on Naruto, their relationship evolves into a deep and unbreakable bond of mutual understanding and support.
Naruto's character development would be quite interesting. His relationships with his friends would change. Some might be jealous of his new power, while others would be worried for him. He would have to constantly balance his old ninja self with this new aspect of having a kagune. He'd also have to deal with the fact that the kagune might have its own will or instincts, and he'd need to assert his own will over it. This inner struggle could lead to a more nuanced and mature Naruto.
He could become more confident, bordering on overconfident. Since he has unlimited strength, he might not face the same challenges in terms of combat, so his development would shift towards moral and ethical challenges.
Naruto's character would likely become more guarded at first. In a crossover with the Attack on Titan world, for example, after being abandoned and then thrust into a world full of Titans, he'd have to be more cautious. He might not be as open and trusting as he was in his original world. But over time, his natural determination and will to protect others would still shine through as he learns to fight Titans.
Naruto would become more mature. With Minato's memories, he'd have a different view on life and responsibilities. He might be less impulsive as he'd understand the consequences of actions better, like Minato did.
He would become more confident. Having telekinesis would give him an edge in battles and make him feel more in control. For example, he wouldn't have to rely solely on his physical strength or ninjutsu. This new power could also make him more responsible as he realizes the potential harm it could cause if misused.
Naruto's development would be exponential. His fighting style would change as he'd incorporate his father's jutsu knowledge. His emotional intelligence would also increase because of his mother's memories of handling relationships. He'd be more in control of his emotions and actions, not just acting on impulse like before.
Naruto's view of himself and his purpose in life could also change. He might start to question his identity as the Jinchuuriki of the Nine - Tails. With new DNA - based powers, he could feel like he has a different role to play in the ninja world. He might explore new ways to use his powers for the greater good, which would be a significant development in his character.
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.
