His character development would likely be much darker. He would lack the initial source of love and support that Kushina was supposed to provide. This could make him more distrustful of others. For example, he might not be as quick to form bonds with his teammates in the same way he did in the original story.
His training would likely be more intense. Since he has the blood of Kyuubi, he might have a natural affinity for chakra control and large amounts of chakra. So, his training could focus on refining and mastering this huge chakra reserve from an early age. For example, he could be taught advanced chakra - based jutsu much earlier than in the original story.
In such a fanfiction scenario, Naruto's character development would likely be deeply affected. He would probably grow up with a stronger sense of self - doubt and a more desperate need for acceptance. Without Kushina's love and support, he might be more withdrawn initially. However, this could also fuel his determination to prove himself even more, making him strive harder to become a great ninja.
Naruto would likely be more confident earlier. Since the Kyuubi bloodline gives him great power, he might not face as much ridicule from the villagers. This would change his initial motivation from seeking recognition to something more like fully mastering his bloodline powers.
His character development would likely be more extreme. With Superman's abilities like super strength, flight and heat vision, Naruto would face different challenges. He might become overconfident at first. But as he realizes the great power also comes with great responsibility, similar to Superman's ethos, he would learn to be more humble and use his powers for the good of the entire ninja world, not just his village.
His training would likely be more intense. Since Kyuubi is a very powerful being, she would push Naruto to his limits. For instance, she might teach him more advanced chakra control techniques earlier than in the original story.
In this kind of fanfiction, Naruto could also end up leaving the village in search of answers about his abandonment. Along the way, he might encounter other outcasts or people with their own troubled pasts. They could form a sort of makeshift family or team. This journey could lead to Naruto discovering new powers or secrets about his heritage that were previously unknown to him. He may return to the village later with a new perspective and new abilities, ready to prove himself despite being abandoned.
Naruto's character would likely be more reserved in some ways. Kakashi is a rather stoic and composed person, and his influence might make Naruto less brash. Instead of always charging headfirst into situations, he would think more. For example, in battles, he might analyze the situation like Kakashi does before acting.
Well, Naruto's character would be different in many ways. Firstly, he'd have a stronger sense of discipline. Kakashi would instill in him the importance of following rules and regulations in the shinobi world. His view of friendship might also be different. While he'd still value his friends, he might be more guarded initially, as Kakashi might teach him to be cautious. His relationship with the Hokage and the village elders would also be distinct. He might have more respect for their authority due to Kakashi's influence, but at the same time, he could be more critical of their decisions if he felt they were not in the best interest of the village, based on the knowledge and values Kakashi has imparted to him.
Naruto's social skills would also be different. Instead of being the lonely outcast, he would be part of a family. He would interact with other ninja kids in a more positive way. His parents could also guide him in making friends. He might be more diplomatic in his relationships because he has seen how his father, as the Hokage, dealt with people. This would all contribute to a very different Naruto compared to the one we know from the original series.
Naruto's character development would take a very different path. Since he has the Rinnegan from birth, he would be more isolated in a way. People might fear him or envy him. This would force him to be more self - reliant at first. His view of the world would be different too. He might not see the need to prove himself as much as he did in the original story. However, as he grows up, he would come to understand that power alone is not enough. He would still need to develop his emotional intelligence, his relationships, and his understanding of the ninja world. So, his growth would be about learning to balance his immense power with his values and relationships, which is a very different journey from his original character development.
