It would change the power dynamics. With her succubus powers, fem Naruto could disrupt the traditional balance of strength. For instance, she might be able to defeat stronger opponents more easily by using her charm and allure.
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 Naruto universe in several ways. Firstly, Fem Orochimaru's actions would be different from the male Orochimaru's. Her motives for taking Naruto might not be as purely power - hungry. This could lead to different alliances and enmities. For example, some characters who were against Orochimaru might be more lenient towards Fem Orochimaru if she shows a more benevolent side. Secondly, Naruto's growth and development would be altered. Instead of following the path with Jiraiya, he's with Fem Orochimaru. So his jutsu and combat style might incorporate more of her unorthodox and perhaps more feminine - influenced techniques. Also, the perception of Orochimaru's lair or hideouts would change. It could be less of a spooky, evil - filled place and more of a place of mystery and potential redemption.
Their relationship would become more complex. Sasuke would probably be more protective of Fem Naruto. Instead of just seeing her as a rival, he would have an added layer of emotional investment.
The power dynamics could shift. In fanfiction, new powers could be introduced to Naruto, making him even more powerful. This would change how he is perceived in the Naruto universe and how he interacts with other characters like Sasuke and Sakura.
The power balance would be greatly affected. If fanfiction gives Naruto some overpowered abilities like instant teleportation across any distance, it would make many of his battles much easier. Enemies that were once a threat would no longer be so.
The power dynamics would shift significantly. Naruto already being very powerful, with the connection to Kaguya, he might be seen as an even greater threat or asset. Allies and enemies would likely reevaluate their relationships with him.
If Naruto was Kenpachi - inspired in a fanfiction, the ninja world would see a more aggressive Naruto. He'd be quicker to engage in combat, which could either intimidate his enemies or make some of the more diplomatic ninja a bit wary. His new attitude might also inspire some of the younger ninja to be more bold in their training and battles.
The Naruto universe would be completely desolate. There would be no more ninja villages, no more clans, and no more shinobi way. It would be a world filled with silence and death.
It would change the combat dynamics a great deal. Guns are much more powerful in terms of long - range attacks compared to traditional ninja weapons. This would mean that strategies for battles, both in the village and against enemies, would need to be rethought. For instance, the importance of cover and stealth would increase significantly.
Well, Naruto getting a Keyblade would be a wild turn. Firstly, the Keyblade has a certain magic to it. Naruto's world is mainly about chakra, but with a Keyblade, he could introduce a new form of energy. He might be able to combine chakra with the power of the Keyblade. In terms of his friends, they would be both amazed and a bit envious. Sasuke, for instance, would see it as another way Naruto is getting stronger. And Naruto would have to learn how to wield it properly. He might start training with it in the same way he did with his rasengan, trying to master all its functions and forms.
