Naruto himself could be a likely time - traveler. He has a strong sense of justice and a desire to protect his friends and the village. If he saw a way to go back in time and prevent the destruction and loss in the Fourth Shinobi War, he would probably take it. Plus, his chakra and determination might be what enables the time - travel in the first place.
Maybe in the fanfiction, the time travel causes a mix - up of jutsu knowledge. A character from the future accidentally gives the wrong kind of jutsu knowledge to a past - self or another character during the Fourth Shinobi War. This then leads to new and unforeseen strategies being developed by the shinobi, either for good or bad, depending on how it's used. It could completely change the power dynamics in the war.
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.
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.
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.
I think the 'Fourth Shinobi War Novelization Fanfiction' might focus on exploring the characters' inner thoughts during the war. For example, it could show Naruto's determination in more detail, how he was feeling while facing such a huge threat.
Naruto's Rasengan would be a game - changer. In the Second Shinobi War, such a powerful and unique jutsu would be unheard of. He could use it to take out enemy strongholds or important leaders quickly.
One of the most heartbreaking scenes could be when his friends find out about Naruto's death. For example, Sakura, who has been with Naruto through so much, would be completely shattered. Her reaction of disbelief and then overwhelming grief would be really sad. Another scene might be when the whole village of Konoha hears the news. The silence that would fall over the village, with people just stopping in their tracks, would be a very poignant moment.
One idea could be exploring the backstories of minor characters during the war. For example, how the normal shinobi were feeling and what they were doing on the sidelines. Another could be a what - if scenario where a different alliance was formed among the shinobi villages.
One possible plot twist could be Naruto changing the outcome of a major battle. For example, in the Second Shinobi War, there were many crucial battles. Naruto might use his future knowledge to prevent the death of a key ninja. This would have a huge impact on the future of the ninja world as that ninja could then go on to change other events.
