Well, if Naruto learns magic in a fanfiction, it would be really interesting. Magic might give him the ability to heal in ways that normal medical ninjutsu can't. He could use magic to restore not just physical wounds but also mental and spiritual ones. This would be a huge advantage in a world full of trauma and conflict. Also, his magic - enhanced abilities could attract the attention of other powerful entities from outside the Naruto universe. These entities could either try to recruit him or see him as a threat. It would add a whole new layer of complexity to the story, as Naruto would have to navigate not only his own world's politics and battles but also deal with these new external forces.
If Naruto learned magic in a fanfiction, it could completely change the power dynamics in the Naruto universe. For example, his already formidable combat skills combined with magic could make him nearly unbeatable. He might be able to use magic to enhance his jutsu, like adding an element of fire magic to his Fireball Jutsu to make it even more powerful. Also, it could change his relationships. His friends might view him differently, either with awe or a bit of envy. And his enemies would surely be more afraid of him, forcing them to come up with new strategies to deal with this magically - enhanced Naruto.
Well, in a fanfiction where Spider Man learns magic, it might lead to some really interesting team - ups. He could collaborate with Doctor Strange in a whole new way. Instead of just being the friendly neighborhood Spider - Man, he could become a sort of magic - using superhero. This would attract new enemies as well, perhaps some dark magic - based villains who see him as a threat to their plans in the magical realm.
If Naruto had Arrancar powers, he might gain the ability to use Cero, which is a powerful energy blast. This could replace his Rasengan in some ways, or he could combine them for an even more devastating attack. His movement would also become more like an Arrancar's, perhaps with the ability to move at high speeds in a more fluid and menacing way. And his appearance might change, with some Arrancar - like features, which would shock his friends and foes alike.
If Naruto were killed by Kushina in a fanfiction, it would completely shatter the Naruto universe as we know it. Naruto is the main character, and his death would mean the end of his journey to become Hokage and bring peace. All the relationships he had built, like with Sasuke, Sakura, and his other friends, would be left in ruins. It would also mean that the prophecy about him might not be fulfilled, leading to a darker and more chaotic future for the Hidden Leaf Village.
If Naruto kills Madara in fanfiction, it could completely shift the power dynamics in the Naruto universe. For one, it might lead to a more peaceful era much sooner as Madara was a major source of conflict. The Akatsuki's plans would likely fall apart without his influence, and the shinobi villages might start to focus more on internal rebuilding and cooperation rather than external threats.
If Naruto and Hanabi got married in a fanfiction, it could change the power dynamics in the village. Their combined strength would make the Hidden Leaf even more formidable. Also, it could lead to new diplomatic relations as other villages might view the union as a sign of a new, stronger Hidden Leaf.
The fanfiction could change the Naruto universe by introducing new threats. With Naruto so powerful, there could be forces that emerge to try and counterbalance his strength. Also, the story could explore different ways of using chakra, as Naruto's merged state might have unique chakra abilities. It could also affect the way ninjas are trained, as they might try to achieve a similar level of power.
It could change the Naruto universe drastically. Naruto is often seen as a symbol of hope. If he were to die, it would shatter the hopes of many characters. The villages that rely on him would be in chaos. Iruka, who holds him, would be forever changed and might become a more somber and withdrawn figure, affecting those around him as well.
Naruto could use his newfound magic to make alliances with other magical beings. This would expand his influence and power base. He could then use these alliances to either seek revenge on those who wronged him or to protect the world from greater threats that the ninja world alone couldn't handle. In this fanfiction, the possibilities are endless as magic adds a whole new dimension to his character.
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.
In a fanfiction where Naruto kills Sasuke at the Uchiha compound, it's a very dark turn. Naruto's character would be severely damaged in the eyes of many. His journey was about saving Sasuke, not killing him. This could also lead to a power vacuum as Sasuke was a powerful shinobi. The Uchiha clan's already tragic story would become even more so. It might also cause Naruto to lose his way, as Sasuke was a sort of mirror to him, and without Sasuke, he might lose his motivation to keep getting stronger.
