One possibility in this fanfiction scenario is that the mind - wipe of Kushina was an accidental result of some experimental jutsu gone wrong in Konoha. This could create a mystery that Naruto and other characters would need to solve.
In a Naruto fanfiction with Kushina's mind - wipe in Konoha, it could change the entire political landscape of the village. Kushina was from the Uzumaki clan, which had a lot of influence. Her being incapacitated in this way could lead to power struggles among different clans and factions in Konoha.
In Naruto fanfiction, a Kushina mind - wipe in Konoha could lead to some really interesting plot twists. Maybe it could be part of a scheme by an enemy to disrupt Naruto's life further. Since Kushina was Naruto's mother, her having a mind - wipe would change the dynamics of how Naruto discovers his family history and heritage.
The relationship between Konoha and the Uzumaki clan might be further strained. With Kushina leaving, Konoha would lose an important link to the Uzumaki. And other Uzumaki members might see this as a sign that Konoha is not a safe place for them.
One possible reason could be to protect Naruto from the hidden threats in Konoha. Maybe she discovers some dark secrets or plots within the village that she believes will endanger Naruto, so she decides to take him away.
One possible reason could be for his safety. Konoha is a well - protected village with many skilled ninja. She might believe that leaving him there would ensure he has the best chance at survival and growth as a ninja. Also, she may have some mission or obligation that forces her to leave him behind, perhaps something related to the greater good of the village or the ninja world in general.
One possible reason could be for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
Yes, it is. In the original Naruto story, Kushina is Naruto's mother and their relationship is based on love and protection. The idea of her wanting Naruto's body goes against this fundamental relationship and is very disturbing as it implies a perversion of the mother - son bond.
Well, if Naruto and Kushina left Konoha in fanfiction, it would change a great deal. Naruto would not have the same relationships with his friends like Sasuke and Sakura. He might develop different fighting styles as he wouldn't be trained by the same people in Konoha. Kushina, being a strong kunoichi, could train Naruto in her own unique ways. And their departure could also cause a stir in Konoha, with some people trying to find them and others realizing the mistakes they made in how they treated Naruto and his family in the past.
I don't think it's a super popular concept in the Naruto fanfiction community. There are so many directions fanfiction can take. Some focus on romance, others on battles or new powers. While Naruto's relation to Konoha is fundamental, the idea of him 'owning' it in fanfiction is not something that seems to be everywhere. That said, there may be some fanfictions out there that play with this idea, but compared to things like exploring Naruto's heritage or his growth as a ninja, it's probably not as prevalent.
It's popular because Naruto is such a central character in the Naruto universe. He has a unique backstory and a set of abilities that make him a natural savior for Konoha. Fans like to explore different scenarios where he uses these to help the village.
This kind of fanfiction often involves very inappropriate and unethical concepts. In proper Naruto - related stories, we should focus on positive themes like friendship, growth, and the pursuit of dreams rather than such disturbing and improper ideas.
