In some fanfictions, if Naruto was sent to the Third Shinobi War, he could change the course of many battles. His unique jutsus like the Rasengan might surprise the enemies. He could also inspire his comrades with his never - give - up attitude.
In a fanfiction about Naruto, the Gura Gura Fruit, and the Third Shinobi War, perhaps the Gura Gura Fruit is a new, mysterious element introduced into the war. Naruto, being the curious and adventurous ninja he is, might be the first to discover it. His friends and allies could be initially wary of this strange power, but as Naruto learns to control it, they see its potential in turning the tide of the war against powerful enemies such as Orochimaru or the Hidden Stone Village's forces.
It could also be a veteran ninja who has already seen a lot in their life but is still drawn into the Third Shinobi War. This character could have a complex backstory, perhaps they lost someone dear in a previous war and are now fighting to prevent the same from happening to others. Their wisdom and experience could be a key factor in the story.
The character development. The Third Shinobi War can be a crucible for Naruto's growth. He could learn new skills, make new friends or enemies, and develop his ninja ideology. It's interesting to see how he evolves from an inexperienced ninja to a more battle - hardened one.
One great Naruto Third Shinobi War time travel fanfiction is 'Back to the War'. It has an interesting plot where the main character goes back in time and tries to change the outcome of the war. The character development is well - done and it stays true to the Naruto universe's lore.
One idea could be to focus on a young and inexperienced ninja who gets caught in the middle of a major battle during the Third Shinobi War. They could witness the horrors of war and have to quickly learn to survive. Maybe they form an unlikely alliance with a ninja from the enemy side who also has a different view on the war.
Rock Lee could be an interesting main character for a Third Shinobi War fanfiction. Since he doesn't rely on ninjutsu, his unique fighting style could be a great asset during the war. We could see him face off against powerful ninjutsu users from other villages and prove that taijutsu is just as effective. Also, his unwavering determination could inspire his comrades during the dark times of the war.
In a Naruto time - travel to the Third Shinobi War fanfiction, Naruto could have a huge impact on the power balance. He could team up with younger versions of his mentors and teach them new things. For instance, he could show Kakashi some new ways to use the Sharingan that he learned from watching Kakashi in his own time. He could also influence the development of the Hidden Villages. If he helps a certain village more than he should, it could shift the political dynamics among the villages. And his presence alone could inspire young ninjas to be better and stronger, as they see someone with such unique abilities.
Madara Uchiha might also be a main antagonist. His goals of reshaping the ninja world could be directly opposed to what Naruto is trying to achieve with his newfound 'godlike' powers. Madara would likely see Naruto as a major obstacle in his grand plan for the shinobi world.
One possible interesting plot could be Naruto having some unique and super - powerful abilities that completely change the course of the Third Shinobi War. For example, he might be able to instantly teleport across the battlefield and surprise the enemy, turning the tides in his side's favor.
