Who might be the main antagonists in a 'naruto gives in to hate fanfic'?

The village elders or certain hidden factions within the village could be antagonists. If Naruto turns dark because of their actions against him, they would naturally be in opposition to him as he seeks revenge or tries to change the village in a way they don't want.

Well, it could be that Naruto discovers some dark secrets about his family or the origin of the Nine - Tails within him. These revelations make him feel betrayed by those he trusted, such as the previous Hokages or his sensei. As a result, he gives in to hate. He might then form alliances with former enemies who also have a grudge against the established shinobi order, and together they plan to overthrow and reshape the world according to their own, more self - serving ideals.

Another possibility is a rival pirate hunter. Someone who is jealous of Sakura's skills or success and tries to get in her way, perhaps by spreading false rumors about her or even directly interfering with her missions.

There could also be some within the wizarding community who oppose Harry learning the Unforgivables. They might see it as a sign that he is turning to the dark side and try to stop him, so they could act as antagonists in the story.

Danzo could be a main antagonist. He's always been power - hungry and has seen Naruto as a threat to his control over the village. After Pain's attack, he seizes the opportunity to turn the villagers against Naruto.

There could be a new, mysterious force that is neither from the Naruto world nor fully part of the Olympian world. This force wants to disrupt the balance between the two worlds and sees Naruto as the key to achieving its goals. It could manipulate both sides and create chaos.

One potential antagonist could be a new and mysterious organization that is similar to Akatsuki but with different motives. They might be interested in using Daisuke to open a portal to a different dimension or something like that. They would be constantly trying to kidnap Daisuke and force him to cooperate. Also, Orochimaru or his remaining followers could be antagonists. Even though Orochimaru has changed somewhat in the series, there could still be some of his followers who are more radical and want to use Daisuke for their dark experiments, believing that he has some special chakra or ability that could help them achieve their twisted goals.

Another option could be Orochimaru. He has his own motives and is always looking for power. He could be the head of a powerful gang in the criminal underworld of the Naruto world. He would constantly be trying to capture Naruto or his friends to use them for his experiments or to gain more power over the ninja world.

There might be some ancient forces or entities that are awakened by Naruto and Sasuke's new 'godlike' status. These could be demons or spirits that were sealed long ago and now see Naruto and Sasuke as threats to their plans of domination. They would be very powerful and require Naruto and Sasuke to use all of their enhanced abilities to defeat.

It could be the village elders. They often have a lot of power and influence in the Naruto universe. If they believe Naruto is a potential threat or they have some ulterior motives, they could be the ones holding him back, thus acting as antagonists.
