Naruto's character development in such a fanfiction would likely be very different from the original. He may become more withdrawn at first, hiding his pain of being ignored. But as time goes on, he could develop a stronger sense of self - reliance. Since he doesn't have his parents' support, he has to figure things out on his own. This might make him a more independent and resourceful ninja in the long run.
Naruto could also develop a rebellious streak. Instead of following the traditional shinobi path to become Hokage, he may choose to go his own way. He might question the values and systems of the Hidden Leaf Village that allowed his parents to ignore him. This could lead to him trying to change things from within the village or even leaving to find a place where he truly belongs. His character would be a complex mix of hurt, anger, and the search for identity outside of his family.
At first, Naruto and Kushina might start to distance themselves from Minato. They could avoid him and not talk to him as much. As time goes on, the hatred might grow deeper. Naruto could start to oppose Minato in public or in important village matters. Kushina might also try to influence others in the village against Minato.
The fanfiction could develop this hatred through the introduction of new characters. These characters might feed Naruto false information about Minato and Kushina, making him question their motives and ultimately hate them. For example, a character who has a grudge against the Uzumaki family could manipulate Naruto.
Perhaps in this fanfiction, Naruto turns to the darker side of the ninja world. Since he lacks the love and guidance from Minato and Kushina, he might be more easily influenced by Orochimaru or other villains. He could start to believe that power is the only way to get respect and recognition, and thus embark on a path that is different from his canon self. He might also form unexpected alliances with characters who are also outcasts in the shinobi society.
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.
He would likely become more self - reliant. Without Minato and Kushina's guidance, Naruto would have to figure things out on his own. He might make more mistakes at first, but those experiences would toughen him up.
Naruto's character may develop a sense of independence. Since he was neglected by Minato, he has to rely on himself more. He becomes more self - reliant and less likely to depend on others for help.
Naruto's character would likely be more confident. With Kushina by his side, he'd have someone to constantly affirm him. He might not have the same desperate need for recognition from the village. His skills could develop faster as Kushina could train him. He'd also have a better understanding of his Uzumaki heritage earlier, which could shape his identity in a different way.
He may develop trust issues. Being abandoned by his mother could make him more cautious about getting close to people. However, this could also make him more determined to prove himself. He might strive to be the best ninja in the village to show that he is worthy of love and acceptance, despite being abandoned. For example, he could push himself extra hard during training.
His character would be more confident. Growing up with parents, he'd have that support system. He wouldn't be as desperate for attention as he was in the original. Instead of seeking validation through pranks, he'd get it from his family. His ninja skills would also develop more smoothly as he'd have Minato's direct training from an early age.
Naruto might become more strategic. Minato was known for his quick thinking and strategic planning in battles. As his reincarnation, Naruto could start to incorporate these traits, making him a more well - rounded fighter. For example, instead of just relying on brute force, he'd consider different ways to approach a fight.
