In the 'dark naruto abandoned by kushina fanfic', Naruto could be shunned by the village due to his mother's abandonment. This isolation drives him to the dark side. He may learn unique and forbidden jutsu from mysterious sources. His goal could be to reshape the ninja world in a way that would make those who abandoned him regret their actions. He might also have internal struggles between the remnants of his good nature and the new - found darkness within him.
The main antagonist could be the Hidden Leaf Village itself. Since Naruto was abandoned by Kushina, the village that failed to take proper care of him could be seen as the enemy. The village elders or those in power who turned a blind eye to his suffering could be the ones he has to oppose.
Well, one possible plot is that Naruto is left all alone at a very young age by Kushina. This makes him an outcast even more so in the village. He might start to question his identity and purpose. He could end up having a different set of friends or allies, perhaps those who are also outcasts. And as he grows, he has to face the fact that his mother abandoned him while still trying to protect the village that didn't always accept him.
Well, it could be that Dark Naruto, after being abandoned, is found by an outcast group. They take him in and teach him their own values which are different from the village's. He grows up with a different perspective and starts to question the whole idea of the ninja world. Eventually, he might try to create his own 'utopia' in his mind, which could involve overthrowing the current system. But at the same time, he still has that internal conflict of his Uzumaki heritage and what Kushina's abandonment means.
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.
His character would likely be more guarded. Without Kushina's love, Naruto may not have the same level of optimism. He might be more prone to anger and have a harder time making friends. He'd have to rely on himself more, which could make him either more independent or more isolated, depending on how he copes with the abandonment.
Well, one possibility is that Dark Naruto would be overjoyed. After all, Kushina is his mother. But at the same time, he could be very conflicted. His dark side might make him suspicious of her motives. He could test her in various ways to see if she's really who she says she is. And Kushina, on her part, would probably be heartbroken to see what her son has become.
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.
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.
It could develop in a complex way. Maybe at first, Kushina is shocked by Naruto's dark transformation. But as a mother, she tries to understand him. She might start by reaching out to him, trying to find the root of his darkness.
