Often, in Naruto fanfiction, Naruto himself could be depicted as the 'god of shinobi' in some alternate universe scenarios. Since he has the Nine - Tails' power and has achieved great feats in the original series, it's not a stretch for some fanfiction writers to take his powers to a god - like level.
Obviously, Naruto would be the main character as it's about him being the 'god of shinobi'. But there could also be other characters like Sasuke, who might be in a different relationship with Naruto now that he is a god - like figure. Sakura could also play a role, perhaps as a healer trying to understand Naruto's new powers.
In a lot of fanfiction, Naruto becomes the God of Shinobi. This is often because the writers want to create a more fantastical version of the Naruto world. By making Naruto a god - like figure, they can introduce new elements such as different power hierarchies, new types of jutsu that are on a divine level, and unique relationships with other characters. It's a way to expand the already rich Naruto universe in a very different direction. For example, in some fanfictions, Naruto as the God of Shinobi has the power to reshape the world or even rewrite the laws of chakra. This not only gives the story a new and exciting plot but also allows for a deeper exploration of the concepts introduced in the original Naruto series.
Obviously Naruto would be one of the main characters. Since it's about him becoming the next god of shinobi. There might also be Sasuke, as he has always been an important part of Naruto's story. And perhaps some of the older characters like Kakashi could also play important roles, guiding Naruto in his journey.
Most likely Naruto would be the main character since it's in his name. But there could also be other characters like Sasuke, Sakura, Kakashi etc. as they are important in the Naruto universe and might interact with Naruto in his 'god among shinobi' state.
Often it's a combination of things. His unwavering willpower, which was already a big part of his character in the original series, is intensified in fanfiction. Along with that, his growing list of extraordinary powers. For instance, if he has the ability to control all forms of chakra in a way no one else can, or if he can communicate with the very essence of the shinobi world. These factors combined can make him the God of Shinobi in fanfiction. He becomes a symbol of ultimate power and an enigma that other characters look up to or fear.
Typically, the 'god of shinobi' in Naruto fanfiction would have extremely powerful chakra. This could be chakra on a scale that far surpasses even the most powerful shinobi in the original Naruto series, like Hashirama Senju or Madara Uchiha.
Well, in 'naruto god of shinobi fanfiction', it often explores Naruto attaining a god - like status within the Naruto universe. It could involve him having extraordinary powers, perhaps being able to control all the elements in a way far beyond what was shown in the original series, and having an almost omnipotent influence over the shinobi world.
Naruto himself is often a popular choice in these fanfictions. Since he already has a lot of growth potential in the original series, it's easy to take him to a god - level. Sasuke is also popular as he is Naruto's rival and has his own set of powerful abilities. Another popular character could be Madara Uchiha. Given his already strong powers and complex character, fanfiction writers like to take him to new heights in the god - level shinobi concept.
Obviously, Naruto is one of the main characters as it's about him being a shinobi god. His friends like Sasuke and Sakura are likely to be important as well. They might support Naruto in his new role or have their own story arcs related to Naruto's transformation.
Obviously Naruto would be one of the main characters as the title implies he's the 'god of shinobi'. Sasuke could also be a main character as he has a long - standing relationship with Naruto in the original Naruto story. Sakura might be in it too, since she was part of Team 7 with Naruto and Sasuke.
