Naruto would be devastated. He has always valued his friends highly, and their betrayal would shatter his world. He would likely feel a deep sense of loneliness and confusion. His self - confidence might take a huge hit as he wonders what he did wrong. For example, he might start doubting his own worth and his ability to make good relationships.
Naruto's power might also be affected. If he was betrayed, he could lose the will to fight or train. He might even start to doubt his own purpose. This could lead to a decline in his abilities, which in turn could put the village at risk if he was its main protector.
In a fanfiction where Naruto is betrayed by his friends, it could start with jealousy. Suppose Naruto gets a great power or a special recognition. His friends, feeling overshadowed, might be tricked by an evil force into thinking Naruto is using them. So they betray him, which makes Naruto realize that he has to rely on his own strength and find new allies who truly understand him.
Sometimes in fanfictions, character development takes a dark turn. The friends might have their own personal goals that conflict with Naruto's. They could see Naruto as an obstacle to achieving those goals. Or perhaps there was a long - hidden secret that came to light, which made them change their attitude towards Naruto, leading to the so - called betrayal.
One possible way this could develop is through a misunderstanding. Maybe Naruto is framed for a crime he didn't commit, and his friends believe the false evidence against him. For example, an enemy could plant evidence that makes it seem like Naruto is working with the villains. His friends, not knowing the truth, turn their backs on him. This would lead to Naruto feeling extremely hurt and isolated, and he might have to go on a journey to prove his innocence on his own.
There might also be a sense of self - doubt. Naruto may start to question his own judgment. He thought his friends were true to him, so the betrayal could make him wonder if he was wrong about them all along. He might also doubt his own worthiness as a friend and leader, which could have a long - term impact on his self - esteem.
One possibility is that Naruto could turn to the dark side. After being betrayed by his friends, his faith in the bonds he once cherished is shattered. He might start using his godlike powers for revenge, targeting those who wronged him. This could lead to a series of battles and a whole new dynamic in the Naruto universe.
Naruto might initially be in shock. He has always believed in his friends, so the betrayal would be a huge blow. He could try to reason with them at first.
At first, Naruto would be in disbelief. He has always trusted his friends wholeheartedly, so this would be a huge blow. He might then feel a deep sense of anger and sadness. However, Naruto being Naruto, he would likely also start to look for ways to prove his innocence or the misunderstanding. He might go on a journey of self - discovery to figure out what went wrong and how he can win back his friends' trust, all while dealing with the pain of the betrayal.
