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.
An old and retired shinobi who is forced to come out of retirement due to the extreme circumstances of the Fourth Great Shinobi War. They might have a different perspective on the war compared to the younger shinobi and use their old - fashioned techniques in new and innovative ways.
One idea could be focusing on a young shinobi who is an unknown hero during the war. They might use some unique and forgotten jutsu to turn the tide in crucial battles.
There's also the possibility that a civilian who has no ninja training at all becomes the unexpected hero. They might use their wits and knowledge of the land to help the ninja. For instance, they could lead a group of ninja through a secret passage to avoid an ambush, or they could come up with a strategy to cut off the enemy's supply lines using their understanding of the local economy and trade routes.
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.
Rock Lee is often overlooked in some of the larger war - time stories. His unique taijutsu skills could be really interesting to explore in the context of the Fourth Shinobi War. He could take on some really tough opponents and show off his growth.
I think Obito could be really interesting. His complex backstory and his role in the war were so crucial. You could explore his internal struggle further, like his lingering feelings for Rin and how that influenced his actions during the war in more depth.
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.
If Naruto dies in the Fourth Shinobi War in fanfiction, it would have a huge impact. For one, the morale of the Allied Shinobi Forces would plummet. Naruto was the symbol of hope. Without him, many might lose the will to fight. His friends like Sasuke would be deeply affected. Sasuke's whole journey of redemption was somewhat tied to Naruto. His death could also lead to a power vacuum. Nations that were relying on Naruto's strength and his idea of peace might fall into chaos as they scramble for power or new forms of protection.
In a 'godlike Naruto' Fourth Shinobi War fanfiction, Naruto could have a connection to a divine entity. Maybe he discovers he is a descendant of a god of the ninja world. This newfound heritage gives him superhuman strength, speed, and the power to foresee his opponents' moves. He uses these powers to single - handedly take on Madara Uchiha and Kaguya. His godlike status also earns him the respect and loyalty of all the shinobi clans, uniting them under his leadership against the common enemy.
An older, retired shinobi who is forced to come out of retirement during the shinobi wars. He has old - fashioned techniques but a wealth of experience. He could mentor a group of young shinobi and help them develop new strategies based on his years of combat knowledge.
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.
