In a fanfiction where Naruto befriends Sasuke early, the Akatsuki's plans might be disrupted. Since Sasuke would be less likely to go rogue in search of power, the Akatsuki would have a harder time recruiting him. Also, the relationship between Naruto and Sasuke could inspire other characters. For example, Sakura might see a different side of Sasuke and Naruto's bond could make her more determined to be a better ninja herself. The whole ninja world dynamic would be different as their friendship would have a ripple effect on many events and characters.
A really interesting fanfiction is 'The Forgotten Beginning'. It delves into a scenario where Naruto and Sasuke are friends long before the academy. They grow up side by side, and this early friendship shapes their characters in unique ways. For example, Sasuke becomes more open and Naruto becomes more focused because of their influence on each other. It's a different take on the Naruto - Sasuke relationship that gives a fresh perspective on the whole story.
One great example could be 'The Bond Reformed'. In this fanfic, Naruto uses his unwavering determination to break through Sasuke's cold exterior. He constantly reaches out to Sasuke, sharing memories of their time together as kids. Another is 'A New Path'. Here, Naruto and Sasuke are forced to work together on a mission outside the Hidden Leaf. Through this, they start to understand each other better and their friendship slowly rebuilds. There's also 'Friendship's Redemption' where Naruto has to save Sasuke from a new enemy, and in the process, their friendship is strengthened like never before.
One possible plotline could be that Naruto and Kurama start training together early on. This would give Naruto a huge power boost right from the start. He could learn to control Kurama's chakra in new and unique ways, leading to him being able to perform more advanced jutsu earlier in the story.
In most of these fanfics, the friendship develops through Naruto's persistence. He refuses to let Sasuke go, whether it's physically or emotionally. For example, in some stories, Naruto follows Sasuke on his travels, constantly trying to talk to him and remind him of their bond. Also, shared experiences play a big role. When they face a common enemy or a difficult situation together, it makes them rely on each other more and thus strengthens their friendship.
One possible reason could be their exceptional skills. Naruto might have shown great progress in his Rasengan training earlier than in the original story. And Sasuke could have mastered some advanced Uchiha techniques faster. Their teachers, like Iruka or Kakashi, might have recognized their potential and decided to let them graduate early.
Naruto would be more confident earlier. Since he has Kurama as an ally, he doesn't face as much ridicule from his peers as in the original story. He knows he has power, so he stands up for himself more. For example, when Sasuke acts all high - and - mighty in the early days at the Academy, Naruto can counter him more effectively.
One possible fanfiction could start with Naruto being assigned to a team with Shikamaru for a simple village - protection task. At first, Shikamaru complains about having to work with the noisy Naruto. However, when a group of rogue ninjas attacks the village, Naruto's quick reflexes and Shikamaru's ability to analyze the situation save the day. After that, they start to hang out more. Naruto is always eager to play pranks, and Shikamaru, though reluctant at first, starts to enjoy Naruto's company. They often sit under a tree, with Naruto talking about his dreams of becoming Hokage and Shikamaru sharing his thoughts on life and strategy.
It could make their peers jealous. For example, characters like Shikamaru might feel that Naruto and Sasuke are getting special treatment. But for their mentors, it could strengthen the bond. Kakashi might have more faith in them and train them more intensively. And for Sakura, she might be both proud and a bit envious of Sasuke's early graduation.
Well, in many fanfictions, Naruto might first notice Shino's quiet and reserved nature. He could start by trying to include Shino in group activities. For example, inviting him to team lunches or training sessions. Naruto's outgoing personality gradually breaks through Shino's shell, and they start to bond over their shared experiences in the ninja world, like facing tough enemies together. Their friendship could also be strengthened by Naruto's understanding of Shino's unique abilities with his bugs, and Shino seeing Naruto's determination to protect the village.
