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.
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.
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.
If Naruto were betrayed in RWBY fanfiction, his values would be put to the test. Naruto believes in friendship and hard work. Being betrayed would make him question those beliefs. He might start to become more cynical, which would be a big change from his usual positive self. On the other hand, he could also use this as an opportunity to grow. He could learn about the different values in the RWBY world and try to find a new path. And perhaps, in the end, he would be able to forgive the person who betrayed him, but not without a long and difficult journey.
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.
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, one possible plot could be that Naruto is somehow transported to the Star Wars universe. The Jedi sense his strong force potential within him, which is similar to his chakra in his own world. They decide to adopt him and train him in the ways of the Jedi. He might struggle at first with the different concepts and rules, but his determination from his ninja training helps him adapt quickly.
Well, it might be about Naruto somehow ending up in the Star Wars universe and being the last Jedi. Maybe he uses his ninja skills combined with Jedi powers to fight against the Sith or some new dark force.
Well, it could start with Naruto mysteriously being transported to a cosmic dimension. As the father of the universe, he first has to figure out what that means. Maybe he has the ability to create new planets or life forms. He might meet some of his old friends in new forms in this universe. He could use his sage mode to sense the energy imbalances in the universe and work towards restoring harmony. His character development would be interesting as he goes from a village hero to a universal savior.
One possible plot could be that Naruto is somehow transported to the DC Universe. He might team up with Superman. Naruto's chakra and his ninja skills could be a great addition to Superman's powers when they face a common enemy like Darkseid. Naruto could use his shadow clone jutsu to create multiple decoys, confusing the villains while Superman uses his strength and heat vision to attack.
In this fanfiction, it might be that Sirzechs is being manipulated by some dark force. This dark force convinces Sirzechs that Naruto is evil. As a result, Sirzechs betrays Naruto.
