Another possibility is that Naruto, being the protagonist and having a great willpower, manages to find a way to break the natural laws of death in the Naruto world. This could be through his understanding of the cycle of life and death, which he has witnessed multiple times. He might have some sort of epiphany that allows him to use his own life force or chakra in a self - sacrificing way to revive everyone.
He could use his strong bond with the Nine - Tails. The Nine - Tails has a vast amount of chakra and unique abilities. Naruto, having a symbiotic relationship with it, might find a way to use the Nine - Tails' chakra in a way that can bring back the dead. For example, he could use it to reverse the effects of certain death - causing jutsus or even create a large - scale resurrection jutsu.
Well, in some fanfictions, Naruto might use some super powerful jutsu that he either discovers or creates. Maybe it's a new form of the Rasengan combined with some sealing techniques. It could also be that he taps into some ancient power or makes a deal with some sort of god - like entity within the Naruto universe.
One consequence could be an imbalance in the world's population. There might be too many people for the existing resources, leading to shortages of food, water, and living space.
He might be initially shocked and heartbroken. Naruto has always valued his friends and the village's trust, so when that's suddenly taken away, he's in disbelief. He could try to reason with his friends at first, but when they don't listen, he might become angry and determined to prove his innocence on his own.
He could try to fight back against this hatred. Naruto has a strong will. Instead of just accepting being hated, he might try to prove everyone wrong. He could start by doing good deeds secretly or try to expose any false rumors that are causing people to hate him.
Hashirama's revival might also bring back old wisdom and knowledge. He could teach the new generation of shinobi things that have been lost over time. However, there could also be political issues. Some might not be happy with a long - dead Hokage coming back and potentially interfering in current affairs. And his revival could also have an impact on Naruto's own growth. With Hashirama around, Naruto might have to re - evaluate his role as a leader and a shinobi.
One way could be through some powerful forbidden jutsu. Maybe he discovers a long - lost scroll that contains a jutsu specifically designed to bring back the dead. However, such a jutsu would likely come with a great cost, like sacrificing a large amount of his own chakra or even his life - force.
Well, Naruto is a very popular anime. Everyone loves it. Fanfiction based on it gives people a chance to be creative. They can continue the story in their own way, or even change some parts they didn't like in the original. It's like building on a well - loved foundation. Also, it can attract different types of fans, those who like action, those who like drama, and those who like character development, all can find something in Naruto fanfiction.
Because Naruto has a huge and diverse world. The fanfiction allows fans to explore different scenarios, relationships, and adventures that the original might not have fully delved into. It gives them a chance to see their favorite characters in new situations, like imagining different pairings or what would happen if a certain battle had a different outcome.
The Naruto universe has so many interesting characters. Everyone wants Naruto fanfiction because it gives a chance to dig deeper into these characters. For example, we can see what Sasuke would do in a situation where he has to team up with Orochimaru again. Fanfiction lets fans be creative with the existing Naruto world.
In some fanfics, Naruto might shock everyone by revealing a powerful new jutsu he's secretly been developing. For example, a jutsu that combines all the elements in an unexpected way, which goes against what others thought was possible in the Naruto universe.
It could be that his new 'godlike' power has isolated him. People might be either in awe or afraid of him, and he may feel that he can't be close to others as before. So he acts coldly as a defense mechanism.
