Naruto is still extremely popular in these fanfictions. His never - give - up attitude and his growth as a ninja make him a central figure. People love to read about how he overcomes new challenges during the Fourth Great Ninja War.
There could be a new group of villains who emerged from the shadows. They might have been observing the war and learned from the mistakes of previous antagonists. They could be more powerful and cunning, perhaps using new forms of jutsu or technology that were developed during the war. Maybe they are after some ancient artifacts or secrets that were unearthed during the Fourth Great Ninja War.
Perhaps the fanfiction could explore how Naruto deals with the psychological aftermath of the war. He witnessed so much death and destruction. He might have nightmares or struggle with PTSD. Meanwhile, the other villages may approach the Hidden Leaf for help in various ways, such as asking for resources or training methods, which Naruto has to handle while also taking care of his own village.
One interesting plot twist could be that some of the dead ninjas from previous wars come back not as enemies but as allies with a secret mission to end the cycle of hatred. They might have gained new powers or knowledge in the afterlife that can turn the tide of the Fourth Great Ninja War.
A unique plot. For example, if it changes the way some jutsus are used or creates new strategies in the war. It can make the fanfic stand out from the usual interpretations of the Fourth Ninja War.
The ninjas who were revived in Naruto's fourth ninja war were the ninjas who died in the attack of Uchiha Dashiro, Uchiha Banban, Wave Wind Gate, Thousand Hand Pillars, Ape Flying Asma, Sky Earth Dream Help, Water Moon, and Nine Tails. I recommend reading "Because I'm too afraid of death, I'll order all Susanoku" and "The Throne from Naruto", which involve the topic of the battle between the Uchiha clan and the ninjas. I hope you like this fairy's recommendation. Muah ~😗
It could be an original character. For instance, a young ninja from a small, unremarkable village who has a strong sense of justice and a hidden potential. This character could be inspired by Naruto's own journey, starting from being underestimated but growing into a powerful force during the war.
A civilian who somehow gets involved in the war and discovers they have latent shinobi abilities. They could start as a clumsy and inexperienced character but grow into a powerful force.
One idea could be to focus on a young and unknown ninja who rises to prominence during the war. They might start with simple missions like scouting but gradually become crucial in major battles, perhaps by using a unique and unexpected jutsu.
