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 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 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.
In the 'Naruto Mata Sharingan' fanfiction, it can also change the training and development of characters. A character with this combination of powers would need to train in both Naruto - style chakra control and Sharingan - related skills. This would open up new training methods and challenges. They might also discover new jutsus that are a combination of the two power sources. This would not only change the individual characters but also the overall balance of power in the Naruto universe, as new and unexpected abilities emerge from this unique combination.
The concept can also influence the relationships in the Naruto universe. Naruto being a Jack of All Trades might make some characters respect him more, while others could be jealous. For example, Sasuke might have a different view of Naruto if he sees him mastering all these different skills. It could either bring them closer or create more tension. Moreover, Naruto's newfound skills could attract different mentors or allies. He might get help from unexpected people who are interested in his unique set of abilities, which in turn could change the flow of the story.
The 'Naruto banished demon' concept in fanfictions can completely change the power dynamics. Since Naruto is removed from the village, the balance of power within the village shifts. At the same time, Naruto in exile might gain new powers or knowledge that the village is unaware of, which could potentially make him a greater threat or a powerful ally in the future, depending on how the story unfolds.
Well, it changes a lot. Firstly, it disrupts the relationships. His friends like Sasuke and Sakura would be affected. They might feel abandoned or confused by his new attitude. Secondly, the power dynamics in the villages change. Without Naruto's usual care for justice and protection, other forces could rise and try to take over. For example, some hidden villages might see this as an opportunity to expand their territory.
In this kind of fanfiction, the very fabric of the Naruto universe might be altered in terms of relationships. The reincarnated character could have a different perspective on things like the Uchiha - Senju conflict. They might try to resolve it in a new way, or their presence could even make the conflict more complex as different factions react to their existence and power.
The concept can change the Naruto universe by opening up new storylines. Instead of just the typical ninja missions and battles against the main villains, there could be stories about Naruto trying to understand the true nature of Kyoka Suigetsu. He might have to go on a journey to find out more about the power's origin, and this could lead to exploring new parts of the Naruto world that were previously unknown.
When Naruto is a transmigrant in fanfiction, it often changes his character development. He may have knowledge or skills from his previous life that alter how he approaches training and battles. For example, he could have advanced medical knowledge and use it to save more lives. It also changes his relationships. He might view some characters differently based on his transmigrant experiences. For instance, he could understand the pain of certain villains better and try to rehabilitate them instead of just fighting them.
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.
