Who could be the main antagonist in a 'naruto super ninja fanfic'?

Maybe an entire rival village decides to target the prodigy. They see the potential threat that the prodigy poses to their own village's dominance, so they send their best ninjas to take the prodigy down.

Perhaps it could be a powerful ice spirit that has been awakened by some dark jutsu. This ice spirit has no concept of good or evil but is causing destruction as it spreads ice everywhere. Naruto and his friends would have to find a way to either seal it or make it understand the harm it's causing. In this case, the ice spirit would be the main antagonist as it opposes the well - being of the villages.

It could be Orochimaru. He's always been after power and new jutsu. If Naruto is guarding something really valuable, like a new powerful ninja technique, Orochimaru would be a likely antagonist. He'd stop at nothing to get his hands on it.

It could be Danzo. He was always a bit of a shadowy figure in the Naruto series. In a ninja tribunal fanfiction, he could be working behind the scenes to manipulate the tribunal for his own gains, perhaps trying to get rid of those who oppose his more extreme views on protecting the village.

It could be Orochimaru. He is always after power and Naruto's new silent and perhaps more powerful form could be a threat to his plans, so he would try to stop Naruto.

A powerful and corrupt ninja from another village could also be the main antagonist. This ninja might be jealous of Naruto Regbinks' skills or the attention he gets. He could try to undermine Naruto Regbinks at every turn, starting conflicts between villages and trying to make Naruto Regbinks look bad in the eyes of his own people. This would create a lot of political and personal drama within the fanfiction.

It could be a long - lost relative of Orochimaru. This person might have been secretly studying Orochimaru's forbidden jutsu and developed even more terrifying techniques. They could be seeking revenge on the ninja world for ostracizing Orochimaru.

The Organization in the Claymore world could be the main antagonist. They already have a lot of secrets and do some morally ambiguous things. If Naruto shows up and starts changing the status quo, like teaching Claymore warriors to be more independent, the Organization might see him as a threat and try to eliminate him.

It could be a rogue ninja who was once a student of Orochimaru and has now developed his own dangerous jutsu. He wants to take over the ninja world and believes the old ways are holding everyone back.

Orochimaru could be a great antagonist. He might want to use Shenron's power for his own dark experiments. He could try to steal the dragon balls and manipulate the wishes to gain immortality or create an army of powerful, immortal ninja.
