Naruto's character could become more somber. Learning Shiki Fujin, a very dangerous and potentially self - sacrificing jutsu, might make him more aware of the weight of his responsibilities. He might start to think more about the consequences of his actions and be less impulsive.
Another interesting approach is to focus on the origin of the Shiki Fujin in fanfiction. Maybe create a backstory where it was created by an ancient clan related to Naruto's Uzumaki heritage. This could open up new plotlines and mysteries.
In 'naruto uses shiki fujin fanfic', the story might focus on the consequences of Naruto using this powerful jutsu. It could explore how it affects his relationships with other characters. Since Shiki Fujin is a very dangerous and self - sacrificing jutsu, the fanfic could show how Naruto copes with the risks involved.
One possible plot twist could be that Naruto initially struggles a great deal with Shiki Fujin. Maybe he accidentally activates it in a wrong way and it starts to drain his chakra in an uncontrollable manner. This could lead to a situation where his friends have to step in to save him, and in the process, he discovers a new way to control the jutsu.
Incorporate unexpected twists. For instance, instead of the Shiki Fujin being a last - resort move, make it a move that has some unforeseen side effects that Naruto has to deal with throughout the story. This will keep the readers on their toes.
Well, one place to look could be on fanfiction.net. There are often a variety of Naruto - themed fanfics there, and you might be able to find some that involve Naruto using Shiki Fujin. Another option is Archive of Our Own (AO3). It has a large collection of fan - created works as well.
In some fanfictions, Naruto Shiki might possess the power to manipulate shadow elements in extremely unique ways. For example, he could use his shadow to not only mimic the movements of others but also to create shadow constructs that can be used in combat, like shadow swords or shields.
He might learn a time - traveling jutsu. This would be really cool as it could allow him to go back and change certain events in the Naruto world, or gain knowledge from the past to use in the present battles.
Often, Naruto Shiki's powers develop through intense training. He might face difficult challenges that force him to dig deep and discover new aspects of his abilities. For instance, in a fight against a powerful enemy, he realizes he can merge his shadow powers with his existing ninja techniques to create a more powerful attack.
One possible scenario in this fanfiction could be that Naruto, being banished from his village, stumbles upon a magical realm. There, he might meet a mentor who teaches him magic. This could lead to him developing new powers and a whole new identity, different from the ninja he once was. It could also open up opportunities for crossovers with other magical universes in the fanfiction world.
