In a fanfiction where Naruto kills the Akatsuki, it could lead to a much more peaceful ninja world much sooner. The Akatsuki's plan to capture the tailed beasts was a huge source of unrest. With them out of the picture, the villages might not be as paranoid about security. However, it could also lead to new problems. The power vacuum left by the Akatsuki could be filled by other evil forces or there could be internal power struggles within the villages that were previously united against the Akatsuki threat.
In this fanfiction scenario, Naruto killing the Uchiha clan would make him an outcast in Konoha. The village that once supported him would turn against him. This could lead to Naruto leaving the village and becoming a rogue ninja. He might then form his own group of allies who believe in his cause, whatever that might be in this altered story. It would also change how the Akatsuki views Konoha. Instead of targeting Sasuke, they might target Naruto directly as the one who eliminated the powerful Uchiha clan.
For such a plot to be possible in the fanfiction, it could involve some major changes in the Naruto world. The Akatsuki could have some new secret weapons or techniques. Also, Naruto might be in a situation where he is not able to access his full power, like being poisoned or something. And perhaps the Akatsuki are more united and desperate than ever to achieve their goals, leading them to take out Naruto who is a major obstacle for them.
Well, perhaps in the fanfiction, Naruto kills Orochimaru and the Akatsuki, but it turns out that Orochimaru had a failsafe. His death triggers a powerful curse that starts to affect Naruto and the Hidden Leaf Village. Naruto then has to find a way to break this curse while also dealing with the remaining threats that were associated with the Akatsuki. It could be a race against time to save the village and himself.
Well, if Naruto becomes a Mist Ninja, the whole power dynamic in the Naruto world would change. For one, the Mist Village has its own set of unique jutsus and training methods. Naruto would be exposed to different forms of combat and ninja skills. This could also lead to different alliances. Since Naruto is a central figure, his shift to the Mist Village might make Konoha view the Mist Village in a new light, either as a threat or as a potential closer ally. And his relationships with characters like Sasuke and Sakura would be greatly affected. He might end up having new rivalries within the Mist Village itself.
In a Naruto kills Kabuto fanfiction, it would likely have a big impact on Naruto's character development. Naruto is usually about saving and redeeming his enemies. Killing Kabuto would be a departure from his normal values. This could lead to internal conflict within Naruto. He might struggle with guilt or question his own actions. On the other hand, it could also show his growth in a different way, that he's willing to do whatever it takes to protect his friends and the village. And from a plot perspective, it would create a rift between Naruto and those who believe in second chances, like Tsunade.
Well, in this fanfiction concept, the power balance in Konoha would shift. Tsunade being Naruto's twin would mean there's another strong force in the village. Naruto might be more involved in the village's political and medical aspects earlier on. She could use her Uzumaki blood in combination with Tsunade's teachings for new types of jutsu. In terms of character development, Naruto would face different challenges. Instead of the struggle for male - dominated recognition, it could be about breaking gender norms in the ninja world. And this would also impact how the other villages view Konoha, seeing two powerful female shinobi from the same family.
Yes, it can be quite a common theme. Many Naruto fans like to explore the idea of Naruto taking on the powerful Akatsuki members and defeating them in their own fan - created stories. It allows for a lot of creative freedom in terms of the battles, the power - ups Naruto might get, and the overall plot development.
One possible plot could be Naruto joining the Akatsuki under some false pretense. Maybe he's trying to infiltrate them to gather intelligence for the Leaf Village. He'd have to keep his true identity and motives hidden while interacting with the dangerous members like Itachi and Kisame.
Well, if Naruto had Hashirama's memories, it could completely change the plot. He might gain knowledge about the early days of the Hidden Leaf, like how to better manage the village resources. Also, he could use Hashirama's experience with the tailed beasts to deal with his own situation. For example, Hashirama was able to control the tailed beasts to some extent, and Naruto could learn from that to perhaps have an even better relationship with Kurama.
Well, in this fanfiction scenario where Naruto kills the Uchiha clan, it would mean the end of the Sharingan bloodline in a very unexpected way. This would have huge implications for the ninja world. Without the Uchiha, there would be no potential for the Mangekyou Sharingan or the Eternal Mangekyou Sharingan. The balance of power in the ninja world might shift as the Uchiha were quite powerful. And Naruto himself would be a very different character. He's always been about protecting and saving people, so this act would make him a much darker and more complex figure, almost an anti - hero.
