Another aspect is that Naruto might have a different relationship with the other shinobi. Since they are all focused on the war, they might initially see him as a burden. But as he grows, they could realize his potential earlier. His training might also start earlier and be more combat - oriented, as the village needs all the help it can get during the war.
One implication could be that Naruto grows up in a more war - torn environment. He might see more death and destruction from an early age, which could make him more determined to end wars. For example, he might witness the pain of orphans like himself on a much larger scale, fueling his desire for peace.
It could also mean that his birth is more of a symbol of hope during the dark times of the war. The village, already in chaos, might view his birth as a sign that better days are coming. And perhaps the Third Hokage would be even more protective of him, knowing that he represents a glimmer of light in the midst of all the fighting.
The relationship with the village elders would be complex. They might have seen him as both a great hope and a potential liability. His relationship with the other Jinchuriki could also be different. If he was known earlier as a Jinchuriki, he might have been in contact with others, like Gaara, earlier. And his relationship with Sasuke would have an added layer. Maybe Sasuke's family would have seen Naruto in a different light, knowing he was born before the war and had some sort of special significance.
Well, in a fanfiction where Naruto is born before the Third Shinobi War, it could mean that the prophecy about him might have been known earlier. This could have led to different training methods for him. Maybe the Sannin would have been more involved in his upbringing. Jiraiya could have started training him much earlier, and Tsunade might have been more focused on his physical well - being. Orochimaru, on the other hand, might have seen him as an earlier opportunity for power and tried to manipulate him much sooner. All these changes would have a huge impact on the overall Naruto storyline.
His relationship with Iruka could be more intense. Iruka, who has also lost a lot during the war, might see Naruto as a chance to heal his own wounds. He could be even more nurturing towards Naruto from the start.
One possibility is that it would change his physical abilities in combat. The wings could allow him to have greater mobility, like quickly evading attacks or launching surprise aerial assaults. It might also make him a target, as his unique feature would draw attention from both allies and enemies who might be curious or jealous.
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.
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.
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.
One interesting plot idea could be Naruto using his future knowledge to prevent certain tragedies. For example, he might be able to save some of the ninjas who died in the original war. Another idea is that he could change the power dynamics between the villages. Maybe he teams up with a younger version of an enemy ninja and they form an unexpected alliance that changes the course of the war.
One implication is that he may have stronger ties to his family heritage. He could inherit more Uzumaki - specific powers or knowledge. For example, he might be better at sealing techniques from the start.
