Perhaps in this fanfiction, Naruto, abandoned by Kushina, ends up in a world where ninjas don't exist in the same way. He has to adapt to a completely different lifestyle. But he still holds onto his ninja spirit. As he grows, he discovers secrets about his family that Kushina never told him and that knowledge helps him become stronger and more self - assured.
One character could be the person who finds Naruto after being abandoned. It could be a powerful and kind - hearted samurai from a different world. This samurai takes Naruto under his wing and teaches him about honor and different combat techniques.
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.
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.
I'm not sure specifically as there could be many different plots in such a fanfiction. It might involve Naruto having some god - like powers but being rejected or abandoned by his mother Kushina for various reasons, perhaps due to fear of his power or some dark influence.
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.
The fanfiction would also change the relationship dynamics in the story. 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. It could also affect how Naruto views family in general, making him more cynical or desperate for family love.
A fanfiction crossover between Naruto, Kushina and Fairy Tail could be really interesting. It could involve the unique powers from Naruto and Kushina's world combined with the magic in Fairy Tail. For example, Kushina's chakra chains could interact with Fairy Tail's ice - make magic in some creative ways. Maybe Naruto's shadow clones could be used in a joint mission with Fairy Tail wizards.
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.
