Another reason might be related to their different ideologies within the ANBU. Naruto may have believed in a more collaborative and friendly approach within the organization, while Sasuke might have been more focused on individual achievement and power. This fundamental difference could lead to Naruto hating Sasuke in the fanfiction.
In the original story, Naruto and Sasuke have a complex but deep - rooted friendship. In this fanfiction, the hatred completely flips their relationship. They would no longer be friends but rather rivals or even enemies. There would be no more of Naruto's attempts to bring Sasuke back to the village.
A really interesting fanfiction idea could be that Sasuke in the Anbu discovers a conspiracy within the village that even Naruto as Hokage is unaware of. Sasuke then has to decide whether to go to Naruto directly or investigate further on his own. This would create a lot of tension and drama, as Sasuke's loyalty to the village and his relationship with Naruto are both at stake.
One possible scenario in such a fanfiction could be Naruto as Hokage having to deal with political situations in the village while Sasuke, as an Anbu, is sent on dangerous covert missions. Naruto might rely on Sasuke's intelligence and combat skills from his Anbu work to protect the village from external threats. They could also have some internal conflicts due to their different roles and the secrecy associated with Sasuke's Anbu work.
Another theme is the exploration of the ANBU world itself. These fanfictions often describe the dark and dangerous nature of the ANBU, the strict training, and the complex hierarchy. Sasuke's experience in this world is then contrasted with his relationship with Naruto, who represents a more positive and hopeful side of the Naruto universe.
One reason could be a misinterpretation of their complex relationship. In the original story, Naruto actually cares deeply for Sasuke. But in fanfiction, the author might be exploring a 'what if' scenario where Naruto's frustration turns to hate due to Sasuke's repeated betrayals. Another reason could be to create a more angsty or dramatic plot. By having Naruto hate Sasuke, it can introduce new conflicts and character developments that are different from the canon.
Their relationship would be one of mutual respect. Naruto, as Hokage, would trust Sasuke's abilities as an Anbu member. Sasuke, on the other hand, would respect Naruto's leadership. They would be comrades again, but with a new dynamic due to their different positions in the village.
A new character could be created as the main villain. Maybe a rogue ANBU agent who was once a friend of Naruto and Sasuke but has been corrupted by power. This character would know all the ins and outs of the ANBU, making it very difficult for Naruto and Sasuke to stop him as he tries to take over the ninja villages using the secrets he learned while in the ANBU.
In a fanfic scenario, Naruto as Hokage might have some concerns about Sasuke being in the Anbu. He could worry that Sasuke's past and his more solitary nature might not fit well with the Anbu's group dynamics. However, Sasuke proves himself by using his unique skills and insights to protect the village. Meanwhile, Naruto tries to integrate Sasuke more into the village's core, leading to some interesting character - development moments for both of them.
Sure. For example, 'The ANBU Bond' is a popular one. In this fanfic, Sasuke and Naruto are teamed up in ANBU and have to learn to trust each other in a whole new way. Their skills are put to the test as they face tougher enemies and more complex missions. It really delves into their characters and how they've changed since their days in the regular ninja teams.
