If Naruto goes evil in fanfiction, first of all, the power balance in the ninja world would be severely disrupted. He has so many powerful techniques and a lot of chakra. He could easily overpower most of the shinobi. His sense of justice would be warped. Maybe he would think that the only way to achieve true peace is through force and domination. This would lead to him clashing with other villages and even his own former comrades. His relationships with characters like Sasuke would become extremely complicated as they were once rivals but also friends, and now Naruto's evil turn would put Sasuke in a difficult position of whether to fight him or try to bring him back to the light.
Well, in such a fanfiction where Naruto becomes evil, it would be a total upheaval of the Naruto universe we know. His dark side could lead to alliances with villains like Orochimaru. He might start to hunt down those he once considered friends. His change could also be a result of some great betrayal, and his quest for vengeance would make him a very dangerous force. This would not only change the story's dynamic but also the fates of all the characters involved.
Well, in a fanfiction where Naruto is pure evil, the whole Naruto universe would be in chaos. He'd likely form alliances with villains. His once - noble goal of becoming Hokage would be replaced by a desire for power and domination. His relationships with characters like Sasuke and Sakura would be completely different. Instead of protecting them, he might target them. And the ninja world would have to unite in a different way, against Naruto this time.
Well, if Naruto becomes the Kyuubi in the fanfiction, he would likely have an overwhelming amount of power. He might be able to defeat his enemies with ease. But he would also face the struggle of controlling such a powerful and wild force inside him. Maybe his friends would be both in awe and a bit scared of him at first.
Well, if Naruto becomes the reaper in fanfiction, he would probably have a whole new set of powers. He could start reaping souls in the Naruto universe, which would be a huge change. Maybe he'd use his new reaper abilities to deal with the more dangerous enemies in a different way, like sending their souls to some sort of afterlife realm.
If Naruto becomes an Arrancar in a fanfiction, he would likely gain new and powerful abilities. Arrancars have unique Hollow powers, so Naruto might be able to use Cero or other Hollow - based attacks. His physical abilities could also be enhanced, and his appearance would change to something more like an Arrancar. He might struggle with the more evil tendencies that come with being an Arrancar at first, but being Naruto, he would probably find a way to use these new powers for good and protect his friends and the village in a different way.
Well, if Naruto becomes Mikoto, he would be a female in the body of Mikoto. He could bring his own values and experiences as Naruto. This could potentially change the relationship dynamics within the Uchiha clan. He may try to bridge the gap between the Uchiha and the rest of the village in a way that Mikoto might not have been able to do in the original story due to her own limitations and the circumstances of the time.
If Naruto becomes the Flash in fanfiction, he would be incredibly fast. He could use his new speed to outmaneuver his enemies in combat. For example, in battles against the Akatsuki, he could zip around and strike them before they even realize it. His Rasengan might also be enhanced as he could deliver it with the speed of the Flash, making it even more powerful and difficult to dodge.
In this kind of fanfiction, Naruto might gain even more incredible power. He could have enhanced physical abilities like super strength and speed, as well as new jutsu related to the bijuu's nature. For example, if he becomes the Nine - Tails bijuu, he might be able to use the Tailed Beast Ball more effectively and on a larger scale. His appearance might also change, perhaps taking on some of the characteristics of the bijuu, like fox - like features if it's the Nine - Tails. This could lead to new relationships and dynamics with other characters. His friends might be in awe of his new power, while his enemies would be even more fearful.
In the 'naruto becomes a dad' fanfiction, Naruto would be passing on his values to his children. He'd be a role model for them. There could be storylines where he has to deal with his kids getting into trouble at the ninja academy. He might also struggle with giving them enough time while still being there for the village. It could show a more mature and responsible side of Naruto as he navigates fatherhood.
In the fanfiction where Naruto becomes a Shinigami, he could potentially have the power to traverse between the world of the living and the dead. This would open up a whole new realm of adventures. He might meet old enemies or friends who have passed away and learn things that could help him in the living world. Also, his Shinigami form could give him a different appearance, like the traditional Shinigami robes and a scythe - which would be a really cool visual transformation for him.
Well, he'd probably be super OP. He already has his ninja skills and if he gets the Avatar powers on top of that, he could be nearly unbeatable. He might use the Avatar state to enhance his Rasengan or something.
