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.
In a 'Naruto 5th Great Ninja War Fanfiction', the story could start with a strange phenomenon that begins to disrupt the chakra balance in the ninja world. This is a sign of the approaching war. As the war breaks out, the younger generation of ninjas, inspired by Naruto's heroics in the previous wars, step up to fight. They face off against a coalition of rogue ninjas who are being controlled by a shadowy figure with a vendetta against the established ninja order. Along the way, there are many battles, with each side using new and creative jutsus and strategies.
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 ~😗
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.
It could be a long - lost relative of Orochimaru. This person might have been secretly studying Orochimaru's forbidden jutsu and developed even more terrifying techniques. They could be seeking revenge on the ninja world for ostracizing Orochimaru.
