Well, it could make the plot more complex. Naruto's new ability might give him an edge in battles. For example, if he summons kami during a fight with a powerful enemy like Sasuke, it could turn the tide. Kami might have special powers that Naruto can use to his advantage, like some sort of super - healing or powerful attack that was previously unavailable to him.
In the fanfiction, Naruto's ability to summon kami would be a game - changer for the plot. Firstly, it would expand the world - building. The concept of kami in the Naruto universe is not fully explored in the original, so this would add a new layer. It could also change Naruto's character arc. He might become more confident or more cautious depending on how he perceives the power of the kami. Moreover, it would affect the power balance among the characters. This new ability could either make Naruto the strongest or put a huge target on his back, leading to various plot twists and turns.
Maybe Jiraiya. Since Jiraiya was Naruto's mentor and taught him a lot of things. He might have some knowledge about summoning kami and pass it on to Naruto.
The ability to summon foxes might make Naruto more of a target. Villains would be interested in his new power. This could lead to more dangerous and complex storylines as Naruto has to not only protect himself but also the foxes he summons. It could also lead to new alliances as other characters see the potential of the foxes in the fight against common enemies.
In some fanfictions, Naruto might gain the ability to summon zombies through dark magic or a forbidden jutsu he discovers. Maybe he stumbles upon an ancient scroll that teaches him this unorthodox summoning technique.
Well, it could change the power dynamics completely. If Naruto can summon duel monsters, he might have an extra edge in battles. For example, against strong opponents like Pain or Madara. He could use the monsters' unique abilities to turn the tide of the fight, which would make the plot more unpredictable as his enemies would have to deal with not just Naruto but also his summoned monsters.
Kami can play a significant role in Naruto fanfiction. One way is through its connection to the spiritual side of the Naruto universe. Kami could help Naruto or other characters in their spiritual growth. This could be like helping them to better understand the chakra system or how to connect with their inner selves. Additionally, Kami might have a role in the balance of the ninja world in fanfiction. It could ensure that the power levels among different ninja clans or villages remain in a state of equilibrium, which in turn affects the plot and the actions of the characters.
Naruto might become more patient. Kami's training is likely to be intense and require a lot of concentration. So, Naruto would have to learn to be patient to master the new skills.
His relationship with the older generations like Kakashi and Tsunade could shift. They would see Naruto as a more mature and capable ninja. Naruto could use the insights from his doujutsu to contribute more to the decision - making in the village, and they would respect his opinions more.
One possibility could be that it completely changes the power dynamics. A female Kami as Naruto's father might introduce a more nurturing yet still powerful figure. She could pass on different types of chakra or special abilities to Naruto in a way that is unique compared to the original story. For example, instead of the more brute - force - like training Naruto might have received in the canon, he could get more spiritual and intuitive training from his 'father' who, being Kami, has a different perspective on power and growth.
Maybe it's a completely new and unknown kami. A kami created specifically for this fanfiction. This kami could have unique powers and a different view of the ninja world compared to the existing characters in Naruto. It would add a fresh and exciting element to the story.
Maybe it's an existing character from Naruto who has been elevated to Kami status. For example, Tsunade could be turned into a Kami, and Naruto's relationship with her could be a very different dynamic from their previous ninja - leader relationship. Or it could be Kaguya, who was already a very powerful being, and in this fanfiction, she reforms and becomes a Kami and Naruto's wife.
