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 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.
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.
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.
One possible reason could be some sort of dark force influencing Kushina's mind. Maybe she was under a powerful genjutsu that made her think she had to abandon Naruto for his own safety, even though it was a false perception.

Well, in such a fanfiction, Naruto might initially be filled with anger and confusion. He may have a harder time connecting with his peers in the village. As he gets older, he could start to piece together the events that led to Kushina's abandonment. Maybe there was some dark force or misunderstanding that caused it. This could lead to a whole series of adventures where he tries to set things right or find a new family in the form of his friends and mentors.
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.

For instance, Naruto's relationship with his father Minato would be more complex as he might also feel some resentment towards Minato for not preventing Kushina from leaving.
