Who could be the main antagonists in a 'naruto god of nature fanfiction'?

The Titans related to chaos and destruction of nature could be great antagonists. For example, Cronus might want to use Percy's newfound power as the God of Nature to further his own dark plans.

Another antagonist could be a powerful and corrupted legendary Pokemon. It could be causing chaos in the Pokemon world and Naruto would have to use his skills and the power of his Pokemon team to stop it. This would be a great challenge as legendary Pokemon are extremely powerful, but Naruto has his own set of unique abilities that could give him an edge.

Another possibility is that the very entity that bestowed god - like powers on Naruto has an ulterior motive. It could turn out to be the true antagonist, using Naruto as a pawn in its grand scheme. This entity might be manipulating Naruto to cause chaos in the ninja world so that it can feed on the negative energy or fulfill some other dark purpose.

The Akatsuki could still be the main antagonists. Even though Naruto is the'son of god', they might see his power as a threat to their own goals. For example, Pain might believe that Naruto's new - found status will disrupt the cycle of pain and suffering that he wants to maintain in the world.

It could be other shinobi who envy Naruto's new - found connection to the primordial god. They might see his power as a threat to their own status and ambitions, and thus try to undermine or even kill him.

It could be a new group of ninjas who oppose Naruto's new - found power as the 'god of blades'. They might be jealous or see him as a threat to their own power - hungry plans.

It could be the traditional God of War villains like the gods who oppose Izuku. Maybe Ares, if he's still around in the fanfiction's version of the God of War world, would see Izuku as a threat and try to stop him.

Perhaps the very magic that made Harry a god has a sort of negative side - effect. This could manifest as a shadowy entity within Harry that tries to take over his mind and use his powers for evil. So, in a way, this internal struggle could be the main antagonist in the story.

The old - fashioned and conservative gods who don't like the idea of a new, young god like Percy shaking up their established order could be antagonists. They might see him as a threat to their power and try to undermine him.

In this kind of fanfiction, the Titans could also be antagonists. They might want to use Percy's power over time to their advantage. Maybe they think they can rewrite history in a way that would bring them back to power. Kronos, in particular, if he were somehow still a threat, could be a major adversary. He could try to manipulate Percy into using his time powers in a way that would benefit the Titans, like going back and changing events that led to their downfall.
