It could be an old - fashioned village elder who has always been against Naruto. They might see him as a threat to the traditional way of life in the village and so start spreading rumors that lead to the villagers turning on him.
Percy could be the instigator if he has a moment of rage or is misinformed. His impulsive nature might lead him to start the fight without fully understanding the situation.
One possible plotline could be that the villagers, out of long - held fear and jealousy of Naruto's growing power, band together in a mob. They might ambush Naruto when he is least expecting it, perhaps on his way back from a mission. Another could be that they are influenced by a powerful and evil - minded individual who manipulates them into believing Naruto is a threat to their safety.
It could be a random civilian. This would show Naruto the impact of the ninja world's violence on ordinary people, making him more determined to protect the innocent.
In Lord of the Mysteries, the instigator was a Sequence 8 aptitude user. He was good at inducing the evil desires in everyone's hearts, intensifying conflicts, and causing bloodshed. Hurry up and click on the link below to return to the super classic " Lord of the Mysteries "!
His father, Minato, could be a likely candidate in a really dark fanfiction. Maybe he was resurrected in an imperfect way and his mind was warped, causing him to turn on Naruto.
One possible reason could be fear. Naruto has the Nine - Tails inside him, and the villagers might be so afraid of the power of the Nine - Tails getting out of control that they decide to take extreme measures. They might see Naruto not as a person but as a potential threat that needs to be eliminated.
Sasuke could turn into the main antagonist if Naruto is killed. Their bond was so strong, and Naruto's death might break Sasuke completely, leading him to go against everything Naruto stood for and become a new threat.
Perhaps Kaguya Otsutsuki is resurrected again, but this time with a stronger will and more dangerous plans. Since Naruto was the one who played a major role in defeating her before, she targets him first in this fanfiction.
One possible reason could be the way the villagers treated him as a child. They ostracized him because he was the host of the Nine - Tails. He was often alone and looked at with fear and disdain, which could have gradually built up his hatred.
Hinata would be devastated. She has always had deep feelings for Naruto. She might lose all hope and become a shell of her former self. Also, Kakashi would feel a great sense of guilt. He was Naruto's teacher and protector in a way. He would probably question his own abilities and actions that led to this situation. And for the village as a whole, it would soon realize the mistake they made when they face new threats without Naruto to protect them.
