Besides Naruto, there might be a young girl named Hana. She could be from a family that was once friends with Naruto's family but now has mixed feelings about him. She's conflicted between her family's stance and her own sense of justice. And then there's Kenji, a strong - willed boy who was also shunned in a different way and he and Naruto form a bond based on their shared experiences.
Their children could be main characters. For example, if they have a son, he could inherit Naruto's determination and Samui's calmness. He might struggle with living up to his father's reputation while also trying to carve out his own identity in the ninja world.
Well, it could be that Naruto is shunned by his family because of some false accusations or misunderstandings. In the fanfiction, he might then go on a journey to discover the truth behind his family's actions. Along the way, he could encounter other outcasts who he bonds with and together they form a sort of 'family' of misfits.
It could be a family member who has a personal vendetta against Naruto and is the main instigator of his being shunned. Maybe an older cousin who is jealous of Naruto's potential.
Sasuke is often a main character in such fanfictions. He could be Naruto's right - hand man, using his skills and intelligence to support Naruto's rule. Their relationship might be more complex, with Sasuke having to come to terms with Naruto's new position of power.
The demihumans themselves would be important characters. There could be a demihuman leader who Naruto teams up with.
Sakura might also play an important role. She could be one of the first to notice the changes in Naruto due to his divine connection. Maybe she tries to help him understand and control his newfound abilities, while also dealing with her own feelings for him in this new context.
There could be the princess of Altomare. She might play a crucial role in helping Naruto understand the city and its needs. Also, some of the local fishermen or sailors could be main characters as they are likely to be affected by any threats to Altomare and could assist Naruto in his guardian duties.
Well, in addition to Naruto, Gaia herself could be considered a main character in a sense, even if she might not be a physical presence all the time. If the fanfiction delves into Naruto's heritage, there could be other characters related to Gaia's past or other 'sons' or 'daughters' of Gaia in the Naruto world. And of course, Naruto's friends like Sakura would also be important. Her reaction to Naruto's new identity could range from shock to being supportive, and she might be involved in Naruto's new adventures related to his connection to Gaia.
Kakashi could play an important role. His experience and wisdom would be valuable in strategizing against the gods. Additionally, characters like Jiraiya might make an appearance, perhaps guiding Naruto from the afterlife or having left some knowledge that helps Naruto in his defiance. Another character could be Gaara. His unique abilities could be crucial in fighting against the gods' minions.
Bulbasaur - girl might be a great choice too. Her connection with nature and plant - based attacks could add an interesting dynamic. She could help Naruto understand the Pokemon world better, especially when it comes to things like finding herbs or dealing with forest - related challenges. There could also be a fiery - tempered Charmander - girl who provides a contrast to Naruto's more easy - going nature and has her own set of powerful fire - type attacks.
