Who could be the main antagonist in 'naruto dragon warrior of kami fanfiction'?

Obviously, Kami would be the main antagonist. Since the title says 'naruto betrayed by kami', Kami is the one doing the betraying, which makes him the bad guy in this fanfiction.

It could be a powerful priest or someone who represents the traditional view of kami. They might see Naruto's forsaking of kami as a threat to their power and beliefs, and thus oppose him.

The plot might involve Naruto being transformed into a dragon warrior by the kami for a specific purpose. It could be to stop an ancient evil that is threatening to destroy the balance of the ninja world. As a dragon warrior, Naruto may have abilities like flight, enhanced strength, and the power to control certain elements. He would have to train hard to fully control these powers and overcome his own doubts and fears. His friends might be initially shocked by his transformation but later support him in his mission.

Maybe a rogue ninja who has somehow tapped into dark powers related to Kami's domain. This ninja wants to use these powers to take over the ninja world, and Naruto, with Kami's help, has to stop him. In this fanfiction, the rogue ninja could have some personal vendetta against Kami as well, which adds more depth to the story.

Another possibility is a corrupted dragon spirit that has been awakened due to the mixing of the two worlds. This spirit could be spreading chaos and trying to destroy both the ninja world and the dragon world. Naruto would have to figure out a way to stop it, as it has powers that are beyond what he has faced before.

It could be a powerful dragon hunter. This person would see Naruto's dragon as a prize to be captured or killed. They might have a personal vendetta against dragon riders in general.

There could be a powerful sorcerer who is jealous of the unique bond between Naruto and the dragon maids. This sorcerer wants to break that bond and take control of the dragon maids' power for himself. He uses dark magic to create illusions and obstacles for Naruto and the dragon maids, trying to turn them against each other so he can achieve his evil goals.

There could be a group of dark ninjas who see Naruto's connection with the dragon as a threat. They believe that Naruto and the dragon together could become too powerful and disrupt their evil plans. So, they set out to destroy the dragon and capture Naruto to prevent them from achieving their goals.

Maybe it's a completely new and unknown kami. A kami created specifically for this fanfiction. This kami could have unique powers and a different view of the ninja world compared to the existing characters in Naruto. It would add a fresh and exciting element to the story.

Maybe it's an existing character from Naruto who has been elevated to Kami status. For example, Tsunade could be turned into a Kami, and Naruto's relationship with her could be a very different dynamic from their previous ninja - leader relationship. Or it could be Kaguya, who was already a very powerful being, and in this fanfiction, she reforms and becomes a Kami and Naruto's wife.
