The relationship would likely become strained. Naruto might start to doubt his friends' loyalty, and his friends would feel guilty once they realize they've been wrong. There would be a lot of tension, and it could take a long time for them to repair the damage.
If Naruto is deeply hurt, he might isolate himself from his friends. This would make his friends realize the gravity of what they've done. They would then have to work hard to regain Naruto's trust. It could involve them proving their loyalty over and over again through various deeds.
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.
He would likely feel extreme loneliness. Naruto has always valued his friends, so being forgotten by them would be like losing a part of himself. He might start to doubt his self - worth, thinking that if his friends could forget him so easily, then maybe he wasn't as important as he thought.
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.
Well, in certain fanfictions, Naruto getting hurt during the bell test can change the dynamic of the team. For example, Sakura could start to see Naruto in a new light, perhaps realizing his determination more deeply. It might also lead to Naruto having to recover for a while, during which time he could have some self - reflection about his skills and how to improve without overexerting himself.
He might have physical injuries that could slow him down in his training or his future battles. For instance, if he gets a deep wound on his leg, it would affect his mobility.
One possible scenario could be that in a battle, Naruto gets seriously injured while protecting Kaka - naru. This could lead to Kaka - naru being extremely worried and taking care of Naruto with great dedication, showing the depth of their relationship.
In a hurt comfort fic, perhaps Sakura has an emotional breakdown after a failed mission. Naruto finds her crying alone. He sits beside her and just listens as she pours out her frustrations. Naruto then shares his own insecurities, like how he sometimes doubts if he can really become Hokage. This mutual sharing of pain and comfort brings them closer, strengthening their friendship in a way that goes beyond their ninja duties.
One reason could be a powerful new enemy. Maybe an enemy with a unique jutsu that catches Naruto off - guard. The consequence would be that his friends would be extremely worried. They would probably rush to his side to protect him and find a way to heal him. His enemies might also take advantage of his weakened state to launch more attacks on the village.
He might be disqualified. If Naruto gets hurt badly during the Genin Exam in fanfiction, the examiners could decide that he is no longer fit to continue and thus disqualify him. This would be a huge setback for him as becoming a Genin is his big dream.
Another possibility is that Naruto has made a decision for the greater good that his friends don't understand at first. For instance, he might have to sacrifice something important that his friends think he shouldn't. So they react negatively and end up hurting Naruto with their harsh words and actions.
