Sasuke is also highly likely to be affected. His relationship with Naruto and his own path of revenge could be drastically different. Maybe a small event that was supposed to bring them closer or push them further apart doesn't happen as expected, leading to a different dynamic between them.
Typically, the main characters are the horse, the rider, and those who were affected by the rider not reaching on time due to the horse's problem caused by the missing nail.
The main character affected is Naruto, no doubt. Since he's the one with the Kyuubi being removed. However, the whole village of Konoha could also be considered as affected characters. Naruto has been a key part of the village's defense with the Kyuubi's power. Without it, the village might face new threats and have to adjust their strategies. And other Jinchuriki in the Naruto world might also be affected in terms of how they view their own situations in comparison to Naruto's.
If a character is tasked with finding the nail, it could be a test of their determination. They might have to overcome many obstacles, and in the process, they become more patient and persistent. For example, if Hinata is on a quest for the nail, she could use this opportunity to prove herself not only to her clan but also to herself, thus growing in confidence.
His friends like Sakura and Shikamaru would be affected too. With Naruto's changes, their relationships with him and with each other could be very different. For example, if Naruto changes the course of events, Sakura might not be as fixated on Sasuke in the same way. And Shikamaru might find himself in different strategic situations due to Naruto's interference.
Madara Uchiha is another character who could be central in such a fanfiction. He had his own reasons for hating the world and seeking power. The 'power of hate' in a fanfiction could be used to delve deeper into his motives and actions, perhaps showing how his hate not only influenced his own life but also had far - reaching consequences for the entire Naruto universe.
Obviously, Naruto himself is the most affected as he has to deal with the knowledge of the future. But his friends like Sasuke, Sakura, and Kakashi would also be deeply affected. If Naruto saw a future where Sasuke was in trouble, he would do everything to change it, which would impact Sasuke's life. Sakura, being Naruto's teammate and also caring about Sasuke, would be involved in any plan Naruto made. And Kakashi, as their sensei, would be there to guide and support them through the changes Naruto tries to make based on his future vision.
In addition to Sasuke, Kakashi, and Sakura, other characters like Iruka sensei would be affected. Iruka was one of the first people to believe in Naruto. Naruto's death would be a huge blow to him. Also, the villagers of Konoha who had started to see Naruto in a new light might have to re - evaluate their views. And characters in the Land of Waves, like Tazuna and his family, who had come to rely on Naruto's help, would also be impacted. They might lose hope or face greater danger without Naruto there to protect them.
His close friends like Sasuke and Sakura would likely be among the most affected. They know Naruto well and seeing him in a terrifying state would be very shocking for them. For Sasuke, who has a deep bond with Naruto, it would be especially hard to face a scary Naruto.
Another plotline might revolve around how the overarching goals of the characters change. In the 'Naruto for want of a nail' concept, a single change can have a domino effect. So, if a certain mission fails due to this small change, the characters might have to reevaluate their long - term goals. Naruto may have to focus on different aspects of his training or a different enemy first, which would completely reshape the story's direction.
In 'deception naruto x sasuke fanfiction', not only Naruto and Sasuke's relationship but also their relationships with other characters like Sakura could be affected. For example, if Sasuke is deceived about Naruto, he might act in a way that makes Sakura misunderstand Naruto too. And Naruto, if deceived about Sasuke, might distance himself from Sakura as he focuses on sorting out the situation with Sasuke.
