One plotline could be that Naruto is tricked into believing the Jedi are hiding a great power that could save his world but are being selfish about it. So, he decides to steal it from them, which is seen as a betrayal. Another could be that he falls in love with a character who is an enemy of the Jedi, and for love, he turns against them.
Well, in this fanfiction scenario, the Jedi Council could betray Naruto because they misunderstand his ninja way. The Jedi are all about peace through control and discipline, while Naruto is more about passion and believing in others no matter what. This clash of ideologies could lead the Council to think Naruto is a danger, so they betray him, perhaps by trying to imprison him or strip him of his powers.
The Jedi Council themselves could be the main antagonists. Since they are the ones betraying Naruto, they would be the ones he has to oppose. Their actions of betrayal would drive the conflict in the story.
Perhaps in this fanfic, Naruto is forced to make a choice between his ninja values and the Jedi code. He might choose something that the Jedi don't agree with, like using his chakra in a way that goes against their light - side - only beliefs. The Jedi then shun him, making Naruto feel betrayed. He might then try to find his own path, separate from both the ninja world and the Jedi order.
In the Naruto fanfiction, the Jedi's powers would be a significant factor when he's betrayed. His Force - enhanced speed and agility could be mistaken for some sort of forbidden ninja jutsu. This would fuel the betrayal as the ninja village might think he's using some dark power. However, as he tries to clear his name, he could start teaching some of the more open - minded ninjas about the Force, showing them that it's not a threat but a potential new source of strength for their world.
Well, perhaps the Jedi, in the Naruto fanfic, is betrayed because he refuses to use his powers in a way that the hidden village wants. For example, they might want him to use the Force to assassinate an enemy leader. When he refuses, they spread false rumors about him being a spy from another land. As a result, he has to team up with some outcast ninjas who believe in his innocence and together they fight against the unjust accusations.
In many fanfictions, Anakin's betrayal by the Jedi Council is often depicted as a complex web of misunderstandings and power plays. One common take is that the Council's secrecy and lack of trust in Anakin, especially regarding his relationship with Padmé, pushed him towards the dark side. They constantly held him at arm's length, not fully accepting him despite his great power.
Naruto's ability to create a large number of shadow clones could be a major factor. In the Star Wars universe, the Jedi might see this as a form of over - powering or unethical power use. They could misunderstand his intentions and think he's trying to overpower them, leading to the feeling of betrayal. For example, if Naruto uses clones to scout a Jedi - held area, they might think he's spying on them for an enemy.
Naruto would initially be confused by the Jedi Code. His world is so different from the Star Wars universe. But as he spends more time with the Jedi Master, he would start to understand. For example, the idea of not using the Force for personal gain would be new to him. He would have to learn to use his newfound Jedi powers in a selfless way. He might also find it hard to let go of his dreams of becoming Hokage in a sense, as the Jedi Code doesn't really have an equivalent goal, but he would try to find a new purpose within the Jedi teachings.
He could be betrayed by a false friend in the DxD world who spreads lies about him. For instance, telling others that Naruto has a hidden agenda to take over their realm.
