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 Iruka, who holds him, would be forever changed and might become a more somber and withdrawn figure, affecting those around him as well.
Well, it would be a huge change. Naruto is the main character, and his death would mean the end of his story in a very tragic way. The balance of power in the ninja world could be thrown off. Enemies might become bolder, and allies would be in mourning. Iruka, having held Naruto in his dying moments, would carry that burden and it could lead to different relationships and power dynamics in the universe.
This situation in the fanfiction could have far - reaching consequences. Since Naruto is such a central figure, his death would cause a ripple effect. The ninja villages would have to reevaluate their security and future plans without him. Iruka's experience of holding Naruto as he dies would not only change his own life but also how others view him. It could inspire some characters to seek revenge, while others might lose faith. The very fabric of the Naruto universe, with its values and beliefs centered around Naruto's ideals, would be torn apart.
The emotional impact could be profound. Iruka has always been an important figure in Naruto's life. If he's holding a dying Naruto, it would be a heart - wrenching moment filled with grief, regret, and a sense of helplessness. It would also show the deep bond between them, perhaps making readers reflect on all the times they've shared together throughout the series.
It also improves Naruto's skills a great deal. He becomes better at combat and using his ninja techniques. For example, his Rasengan might be more powerful or more easily controllable after Iruka's training. Moreover, Naruto's confidence grows under Iruka's guidance. He no longer doubts himself as much and is more willing to take on challenges.
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 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.
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.
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.
