First, Naruto would experience a new level of happiness. This would make him more positive in his outlook. He would no longer carry the same sense of loneliness that had shaped him in the past. In terms of his ninja skills, he might become more strategic, following Minato's guidance. Emotionally, he would be more balanced. He wouldn't be as quick to anger or jump into dangerous situations without thinking. His relationships with others would also change. He could be more of a role model for the younger generation in the village, inspired by his parents' example. And his sense of purpose might shift slightly. Instead of just seeking to be recognized, he would want to make his parents proud, which would add a new dimension to his character development.
The training could also make Naruto more disciplined. Minato and Kushina were both highly disciplined ninjas. Their training methods would likely instill in Naruto a sense of order and routine. He would learn to manage his time better for training, and also be more meticulous in his study of jutsu. This new - found discipline could help him in all aspects of his ninja life, from mission planning to combat.
Meeting his parents would make Naruto more confident. Knowing where he comes from and having that connection would boost his self - esteem. He would have a better understanding of his own strength, as he gets to see the great Minato and the feisty Kushina.
Naruto's character would likely become more confident. With his parents by his side, he'd have a newfound sense of security. He could learn more about his family's history and heritage directly from them. This would make him feel more connected to his roots and might even inspire him to develop new jutsus based on his family's techniques.
If Minato and Kushina disown Naruto in fanfiction, Naruto's character might develop in a very different way. He may grow up with a sense of abandonment that shapes his entire personality. He could become extremely independent but also very lonely. His idea of family would be completely distorted. He might even start to view the concept of 'home' as something he doesn't have or need. This could also make him more empathetic towards other outcasts, as he himself has been cast out by his own parents.
Well, if Minato and Kushina ignored Naruto, it would likely make Naruto grow up feeling extremely unloved and unwanted. He might become more withdrawn and lack the confidence he has in the original story. His drive to be recognized might turn into a desperate need for any kind of attention, not just positive, which could lead him down a much darker path in terms of his character development.
Well, Minato could start training Naruto from a very young age. He could pass on his Flying Thunder God Technique, which would give Naruto a huge advantage in combat. Kushina could train Naruto in the ways of the Uzumaki clan, like their strong chakra reserves and sealing techniques. With both of them alive, Naruto's training would be more comprehensive and personalized compared to what he had in the original story.
Well, it could have a huge impact. If Kushina hurts Naruto in the fanfiction, it might make Naruto more distrustful. He could become more withdrawn and have to work harder to build relationships later on.
Naruto would likely be very confused and hurt. He would grow up with a sense of abandonment that could make him more withdrawn at first. But this could also fuel his determination to prove himself, as he may feel he has to be strong without his parents. He might also be more eager to seek answers about his parents as he gets older.
One possibility is that Minato and Kushina would be overjoyed to see Naruto again. They would probably first have a very emotional reunion, hugging him tightly. Then, Minato could start training Naruto more intensively, passing on some of his most advanced jutsu techniques that he didn't have time to teach before. Kushina, on the other hand, would likely focus on the more motherly aspects. She might cook all of Naruto's favorite meals and give him the love and care he missed during his childhood. Also, their presence could change the political situation in the Hidden Leaf Village as Minato was a respected Hokage. Their return could boost the morale of the villagers and make the village even stronger in the face of threats.
Naruto's character would likely become more mature. Being saved by his parents is a huge event. It could make him more responsible and less impulsive as he realizes he has a legacy to uphold. He would understand that his actions not only affect himself but also the memories of his parents.
