How does the concept of 'Naruto is transmigrant' change the Naruto story in fanfiction?

It changes it a great deal. For example, Naruto's power source becomes more directly related to the Kyuubi. Instead of just having the Kyuubi's chakra, he might be seen as an extension of the Kyuubi itself. This could lead to different relationships with other characters, like Sasuke might view him more as a monster.

The 'dark killer Naruto' concept in fanfiction often alters the overall tone of the story. It becomes more edgy and intense. For instance, the battles are no longer just about protecting the village but also about Naruto's personal vendettas. His actions may not always be morally right, which challenges the reader's perception of what it means to be a hero in the Naruto universe. This can lead to a whole new exploration of the themes of power, friendship, and redemption as Naruto navigates his new, darker identity.

Well, it changes the Naruto story by adding a new layer of humor. Naruto's crossdressing would lead to some really funny moments. For example, when he tries to interact with his male friends while dressed as a girl, their reactions would be quite comical. Also, it could change the way some of the storylines progress. Maybe certain missions would be different because of his new look.

It changes the power structure. If Naruto is a demon, he may have powers that are more raw and uncontrollable. For example, he might not be able to rely on chakra in the same way.

The concept changes the relationships too. Naruto's relationship with Sasuke could be seen in a whole new light. Since Sasuke is related to Indra, they might have a more fated connection. They could be forced to work together more often to fulfill some greater destiny related to their reincarnation status. Also, the way other characters view Naruto could change. They might see him as a more significant figure in the grand scheme of things, not just as a powerful ninja but as a key part of a long - standing cycle.

It changes the family dynamic completely. Instead of the normal mother - son relationship, Naruto has to take on a caretaker role. It can add a layer of cuteness and uniqueness to their interactions.

The 'Naruto Kyuubi Mother' concept can change Naruto's story by adding a new source of guidance. Instead of just relying on Jiraiya or Kakashi, he now has this mysterious connection to the Kyuubi's mother which can lead him in different directions.

It changes the Naruto universe by adding a new element of magic. In the original Naruto, there is mainly ninja magic. But with fem Naruto being a mermaid, there is now water - based magic. For example, she could use her mermaid powers to create water barriers or communicate with sea creatures, which is completely different from what normal ninjas can do.

It changes the power dynamics. Usually, Naruto is a force for good, but as an evil avatar, he becomes a major threat. Villages that once saw him as an ally would now need to strategize against him. For instance, Konoha would have to find ways to contain him without harming him too much, as he was once one of their own.

It adds an element of mystery. Suddenly, there are things in the Naruto world that not everyone can perceive. This can lead to Naruto having a unique role, like a bridge between the living and the dead. For example, he could use the knowledge from ghosts to prevent disasters.
