Well, in such a fanfiction scenario where Naruto becomes the Death God, it would change the entire power dynamic. Naruto, being the Death God, could potentially end wars instantly. He might be able to manipulate the souls of the dead, which could lead to some really interesting plotlines. For example, he could communicate with the souls of past Hokages more directly and gain their wisdom in a whole new way.
Well, when Naruto becomes the Death God in fanfiction, his relationship with Sakura would change. She might be more hesitant around him, as his new power is so otherworldly. And his bond with Kakashi would also be different. Kakashi, being a wise ninja, would try to guide Naruto in using this power responsibly. Naruto's relationships with the villagers would shift too. Some might worship him, while others could be suspicious of his new - found power.
In some fanfictions, Naruto can be depicted as the God of Death. Fanfiction allows for a lot of creative liberties, so authors might come up with such unique concepts. It gives a whole new perspective to the Naruto character and the Naruto universe in general.
In this fanfiction, Naruto could gain the powers of a God of Destruction through a special encounter. Maybe he meets an ancient being who sees his potential. His training to control these powers would be intense. He would have to learn to balance his old ninja values with the new role of maintaining balance in the universe through destruction when necessary.
It's also likely that Naruto becomes a god dragon slayer as a result of a prophecy. The fanfiction could explore how he initially struggles with this new role. He has to deal with the expectations that come with being a 'god' - level dragon slayer. Along the way, he might make new allies, like other dragon slayers or magical creatures who recognize his potential and help him in his journey to master this new power.
I think Hinata would also be an ally. She has always been in love with Naruto and would support him no matter what. And the rest of the Konoha 11 would probably be his allies too. They have all fought together and have a sense of camaraderie. With Naruto as a god - like figure, they could help him spread his message of peace and use his powers to protect the village and the world at large. They would be the ones who understand Naruto the best and would be there to assist him in any way they can.
It could mean a major change in the Naruto universe's cosmology. If Naruto is the God of Death, then concepts like the afterlife and reincarnation might be re - defined according to the fanfiction's plot. Also, his enemies would have to face a much more powerful adversary, which could lead to very different battle scenarios. The whole ninja world would be forced to re - evaluate their understanding of Naruto and his place in their world.
Perhaps in the fanfiction, the God of Death has been observing Naruto's journey all along. When Naruto is on the verge of losing a crucial battle against an overwhelming foe, the God of Death appears and offers him a pact. If Naruto can endure a set of challenges that test his will, his chakra control, and his understanding of life and death, he will be granted the God of Death's powers to turn the tides of the battle.
Well, one key element could be Naruto's new role as a Death God. It might change his abilities and how he interacts with other characters. For example, he could have powers related to death and the afterlife, like being able to judge souls or something.
