In some fanfictions, Naruto's abandonment could cause a rift in the ninja world. His friends might be divided in their opinions about him. Some might side with his family and try to bring him back, while others might think he had his reasons. This division could lead to political unrest or new alliances being formed as everyone tries to deal with the situation.
Well, it could go in many directions. For example, his family might start to search for him, which could lead to a series of adventures where they encounter new characters and face various challenges. His wife, if he has one in the story, might become stronger and more independent in his absence, vowing to bring him back.
In some fanfictions, Naruto might abandon his family due to a false prophecy that convinces him he's a danger to them. He may think that by leaving, he can protect them from harm that might come his way because of his past or enemies.
Naruto might initially be in shock. He has always counted on Kushina's love, and this sudden abandonment would be a huge blow. He could become withdrawn and quiet, not understanding why his mother would do such a thing.
The story could develop in many ways. One way is that Naruto might become a target of the Akatsuki. Since he knows their secrets and has left their group, they would see him as a threat. This could lead to a series of battles where Naruto has to fight against the Akatsuki members one by one to protect himself and his village.
He may develop trust issues. Being abandoned by his mother could make him more cautious about getting close to people. However, this could also make him more determined to prove himself. He might strive to be the best ninja in the village to show that he is worthy of love and acceptance, despite being abandoned. For example, he could push himself extra hard during training.
Well, it would have a huge impact on the other characters. For Sasuke, it could change their dynamic completely. Sasuke might lose his motivation for rivalry as Naruto was a big part of his drive. As for Sakura, she might feel a sense of loss and try to bring Naruto back to his old self. And for the village, it would be a big blow. Naruto was seen as a symbol of hope, so if he abandoned his dream, the morale of the village would likely decline.
Naruto would be devastated. He sees Kakashi as a mentor and father figure. He might initially go into denial, not believing that Kakashi would actually abandon him.
At first, Naruto is likely to be heartbroken. Konoha has been his home, and he has always longed for acceptance from the villagers. So being abandoned would be a huge blow to him.
The story could take a dark turn for Stiles. Without Scott, he might become more vulnerable and attract the wrong kind of attention. He could end up in a dangerous situation that forces him to grow and become stronger on his own.
Well, the story could develop in many ways. Ash might go into a deep depression at first. He has been with Pikachu for so long that its absence would be a huge blow. He could start doubting his abilities as a Pokémon trainer.
He could become very determined to find out why Sakura left and try to win her back. Naruto is known for his perseverance, and he wouldn't give up easily on his family. He might also start to question his own actions and wonder if he could have done something differently to prevent this.
