In a more complex scenario, Naruto could be influenced by an outside force. Let's say an enemy of Konoha uses mind - control or some form of manipulation on Naruto. They make him believe that the ANBU is the enemy of the village and that he needs to take them down. As he betrays the ANBU, he slowly starts to realize that he's been used, but by then he's already in too deep and has to find a way to fix the situation and regain the trust of his friends and the village.
In this fanfiction scenario, Naruto's betrayal by Akeno could be due to a misunderstanding of their goals. Maybe Akeno has been influenced by some dark forces that made her turn against Naruto. It could also be that there is some hidden information that led to this sudden change in their relationship.
In fanfiction, Naruto being betrayed by Akeno could be a very interesting plot twist. It might start with Akeno having some hidden motives or being forced by an external power to turn against Naruto. Maybe she was blackmailed into doing so. This could lead to a whole new set of adventures for Naruto as he tries to figure out why she betrayed him and also deal with the consequences of her actions.
Sasuke could also be a character who is frequently betrayed in these fanfictions. Given his complex personality and his history of being both a loner and a seeker of power, he might be lured into dangerous alliances in the DxD world. And his partners in the DxD world could betray him when they realize they can't control him or when his power becomes a threat to them.
It could mean that in some fan - created fictional works, Naruto is depicted in a way that goes against his original character, like making him do things he would never do in the official story. This can be seen as a 'betrayal' of the essence of Naruto as a character.
One idea could be that their own village betrays them. Maybe there's a power - hungry leader who sees Naruto and his sister as threats to their new regime. They could be framed for a crime they didn't commit and then forced to flee the village. In the process, they might have to rely on some unlikely allies they meet on their journey, like a group of outcasts who also have a grudge against the village.
One idea could be that in the fanfiction, Hinata is under the influence of a powerful genjutsu. This genjutsu makes her see Naruto as a threat to the Hidden Leaf village. So, she betrays him to protect the village in her distorted view. It could lead to a lot of inner conflict for Hinata once she realizes the truth and Naruto having to deal with the pain of her betrayal.
Grayfia in this fanfiction might be a powerful figure. She could be a ninja with unique abilities or a non - ninja with influence in the Naruto world. Since she betrays Naruto, she probably has her own set of beliefs and goals that conflict with Naruto's. Maybe she's part of a secret organization or has a personal vendetta against Naruto that we'll find out as the story progresses.
Naruto would be determined to get to the bottom of it. He would not just accept the betrayal at face value. He would use his skills and the help of his friends to investigate what made Jiraiya turn against him. Naruto's ninja way is about never giving up, and this situation would be no different. He would fight against this betrayal, both physically if Jiraiya became an enemy in combat, and emotionally, trying to understand the reasons behind it all while still holding on to the hope that Jiraiya could be redeemed.
