Who could be the main villain in 'As the Wind Blows Naruto Fanfic'?

I'm not entirely sure as I haven't read the specific 'as the wind blows fanfic' in detail. But usually, the main characters could be those who are most affected by the wind or are somehow central to the concept of the wind in the story. Maybe there is a young adventurer who follows the wind's direction.

A new character could be introduced as the main villain. This character could be someone from an ancient clan that was once in control of the 10 - tailed beast but lost it. Now, seeing Naruto with that power, they want it back and will stop at nothing to get it. They could have unique powers and abilities that make them a formidable foe for Naruto and his friends.

It could be a new character, a powerful dark wizard who wants to use the combined power of Naruto's chakra and Pikachu's electricity for his own evil purposes. He creates all sorts of dark creatures and sends them after Naruto and Pikachu to try and capture them. He's very cunning and has a lot of minions to do his bidding.

It could be a rogue ninja from the village with the Tenshikage. Maybe he's jealous of the Tenshikage's power and wants to take it for himself. He could be causing chaos in the village, stealing important ninja scrolls and attacking innocent villagers.

Maybe an ancient evil spirit that has been awakened due to some mistake. It targets Ageha because she has a pure and powerful chakra. Naruto, being the hero he is, tries to fight the spirit, but he quickly realizes that he needs Ageha's help as well as the help of all his friends to defeat this powerful foe.

The main villain could be Darkseid. Imagine if he somehow finds a way to enter the Naruto universe. He would be a formidable foe for both Naruto and Supergirl. His omega beams and immense strength would be a huge challenge for them to overcome.

A powerful demon named Malice could be the main villain. He has the ability to absorb both chakra and ki, making him a formidable foe for Naruto and Goku. He has a dark plan to destroy both the Naruto universe and the Dragonball Super universe and create his own realm of chaos.

It could be a jealous relative who wants Naruto out of the picture so they can have more attention or power within the family.

It could be a rogue Uchiha who has turned against the clan's values. He might be jealous of Naruto's power and popularity, and decides to use his Uchiha abilities to create chaos in the ninja world. He could also be trying to revive an old and dangerous Uchiha - related technique that was sealed away long ago.

A powerful dark wizard could be the main villain. He could be jealous of the clone's unique powers and want to steal them for himself. He might use dark magic to try and corrupt the clone or simply try to destroy it to prevent it from becoming too powerful.
