Fanfiction about Naruto being abandoned by Minato and Kushina can also be a way to explore different power - up scenarios. Since he doesn't have the emotional support from his parents, he might be forced to seek power in other ways, which could lead to a Naruto with a very different set of skills and abilities compared to the original series.
In this type of fanfiction, the story could also focus on how the village might react differently to Naruto. Without Kushina's presence, which could potentially have been a positive influence, Naruto might face more hostility. His struggle to fit in and gain acceptance could be more arduous, and this could be what drives him to the brink of insanity. Maybe he would develop a more jaded view of the world and the people in it.
One common theme is isolation. Naruto would be all alone without his parents, and this would shape his relationships. Another theme is revenge. In some fanfictions, he might seek revenge on the village for his abandonment.
There would be a lot of anger. Naruto might be angry at his parents for leaving him, and this anger could fuel his determination in some ways. For example, he could strive to become a great ninja just to prove that he didn't need them. But it could also cause problems in his relationships, as he might lash out when reminded of his abandonment.
In many Naruto fanfictions where Naruto meets Kushina and Minato, it often creates a very emotional scenario. Naruto finally gets to meet his parents who he has only heard about. It could be a heart - warming reunion where they share stories, hugs, and Minato and Kushina get to see how far Naruto has come.
On a more personal level, they could face internal guilt. As Naruto grows up and achieves great things on his own despite their neglect, Minato and Kushina may realize what they've missed out on. This realization could cause them a great deal of internal turmoil and regret for not being there for their son when he needed them.
One possible aspect to analyze in a Kushina x Minato fanfic could be their relationship dynamics. Their love was strong and Minato was always very protective of Kushina. Fanfics might explore their courtship in more detail, like how they first fell for each other.
In this fanfiction, Naruto could be found by a different ninja. Maybe an older, retired ninja takes him in. This new caretaker could teach Naruto different values and skills than what he would have learned from his parents. As a result, Naruto's personality might develop in a unique way, less influenced by the Uzumaki and Namikaze clans.
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.
A possible plotline is that Naruto gets adopted by a group outside the village. He grows up learning their ways and becomes a sort of outcast from Konoha. Then, he could return to the village with a different set of skills and a new perspective. Or, he might develop a vendetta against Konoha for allowing his abandonment and try to take revenge in some way.
In this fanfic scenario, Naruto's character could take a darker turn. Maybe he becomes more solitary and distrustful. His sister, on the other hand, might be favored by Kushina but have her own internal struggles. The story could explore how Naruto overcomes his feelings of being abandoned and reconciles with his family.
