There could be a young and ambitious ninja as the main character in 'naruto sharingan god fanfic'. This ninja starts out as an underdog but with the discovery of the Sharingan God, their life changes completely. There might also be a mentor - like figure, perhaps an old and wise ninja who has some knowledge about the Sharingan God and helps the main character on their journey. Additionally, there could be antagonists, like other power - hungry ninjas who want the Sharingan God power for themselves.
Often in these fanfics, the main character with the Sharingan God is surrounded by a group of friends or comrades. These characters may have their own unique abilities and personalities. For example, there could be a healer in the group who helps the main character when they get injured during battles related to the Sharingan God power. There could also be a strategist who comes up with plans to protect the main character from those who want to steal the power. And of course, there are usually some villains who are after the Sharingan God power and will stop at nothing to get it.
There could also be original characters created specifically for this fanfic. These new characters might have their own motives related to the Sharingan. For example, a new character could be a researcher who is trying to unlock the ultimate power of the Sharingan and sees Naruto as a key subject. They could add a whole new dynamic to the story.
It could be Sasuke. Since the fanfic has 'Sharingan' in the title, Sasuke, who is well - known for his Sharingan abilities in the original Naruto series, might be one of the main characters.
I'm not sure exactly as it's a fanfic, but likely there will be a character inspired by Naruto. There might also be characters related to the Sharingan's origin or those who are affected by the power of the 'holy' Sharingan.
Another possibility is that it could involve Naruto as a main character even though he doesn't have the Sharingan. His relationship with the character having the Eternal Sharingan could be explored. Maybe Naruto helps the character come to terms with their power or they team up to face a common enemy. This would add an interesting dynamic to the fanfic as Naruto's ideals and the power of the Eternal Sharingan collide and combine in different ways.
Obviously, Naruto is the main character. He is the one who becomes this 'god - like' figure in the fanfic. But there are also other important characters like Sasuke. Sasuke might play a role in either supporting Naruto's new power or being in conflict with him because of it.
It could be Sasuke. Since he has the Sharingan, in fanfiction about the Eternal Sharingan, he might be a central figure, evolving his powers further.
Other characters like Sakura might be involved as well. She could be curious about how Naruto got the Sharingan and how it changes his abilities. Characters from the Uchiha clan, even if they are just mentioned in flashbacks, could be important. For example, Itachi's actions and the secrets he held about the Sharingan could be explored more deeply in relation to Naruto now having this power. And then there are the villains. They might see Naruto with the Sharingan as a new and greater threat or as an opportunity to gain power for themselves.
In this fanfic, Naruto is the central figure as the 'mortal god'. But we might also see characters like Kakashi playing a significant role. He could be acting as a mentor or guide to Naruto, helping him come to terms with his new powers and the responsibilities that come with it. And then there could be new characters introduced specifically for this fanfic, perhaps some ancient beings who have knowledge about the 'mortal god' concept and interact with Naruto.
In addition to Naruto and Sasuke, characters like Kakashi could also be main characters. He is a very popular character in the Naruto series, and his wisdom and combat skills could be crucial in a story involving the 'death god'. Also, characters like Sakura might be there. She could be involved in the story either as a healer or as someone who also has to deal with the new and dangerous elements brought by the 'death god' 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.
