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.
In a fanfiction where Naruto gets a Keyblade, his fighting style would be revolutionized. The Keyblade is not just a weapon but also a symbol of connection to different worlds in its own lore. Naruto could potentially use it to travel to other dimensions, which would open up a whole new set of adventures. He could bring back knowledge or power from these other dimensions to help in his fight against the Akatsuki or other threats in his own world. Also, the Keyblade's design might attract the attention of collectors or enemies who want to steal it for its power. Naruto would have to protect it at all costs, and this could lead to some really interesting story arcs.
If he wishes for peace, the entire political structure of the ninja world would change. There would be no need for the hidden villages to constantly be on guard against each other. This could lead to a more unified ninja world where resources are shared, and everyone can progress together.
Well, he'd probably be an even more powerful force. The Keyblade has its own unique powers and abilities. Naruto's already strong ninja skills combined with the Keyblade could make him nearly unbeatable. He might use it in combat in ways similar to how he uses his ninja tools, but with added magical elements. For example, he could use his chakra to enhance the Keyblade's attacks.
His fighting style would likely incorporate more acrobatic moves. Since the Keyblade can be used for things like jumps and dashes in mid - air, Naruto would start using these abilities. He might also use the Keyblade to block attacks more effectively than he could with just his kunai or shuriken. And he could use the Keyblade's power to enhance his speed, allowing him to quickly close the distance between him and his opponents or dodge attacks more easily.
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.
In a fanfiction where Naruto kills Sasuke and obtains the Sharingan, it would be a game - changer for the story. Naruto would gain new abilities like enhanced visual perception and the potential to use some of the Uchiha's signature jutsu. However, this would also create a lot of internal conflict within Naruto. His ninja way has always been about saving his friends, not killing them. So, this act would make him question his own identity and values. Moreover, the political situation in the ninja world would be in chaos. The Uchiha clan's power being transferred to Naruto, an outsider in terms of the Uchiha, would be a controversial matter that could spark new rivalries and alliances.
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.
