One possible plot could be that Naruto feels abandoned by Sakura after she chooses Sasuke over him. Naruto then goes on a journey of self - discovery, training harder than ever to prove his worth not just to Sakura but to the whole village. He might face new enemies alone and form unexpected alliances, all while dealing with the emotional pain of being left behind.
Maybe a mysterious ninja from a hidden clan shows up. This ninja is intrigued by Naruto's situation of being left behind by Sakura and decides to help him. They could have some really cool powers like the ability to manipulate shadows in a different way than the Nara clan. Also, there could be a healer from a neighboring village who comes to Konoha. She helps Naruto deal with his emotional wounds from being left behind, and in the process, they become good friends.
In a fanfic, if Naruto is left behind by his team, he might first feel a sense of abandonment. He could then use this as motivation to train harder on his own. For example, he might discover new jutsu or ways to improve his skills. He could also cross paths with other characters who help him grow in different ways, like an old hermit who teaches him some unique wisdom.
Naruto might initially feel angry. He'd probably think about all the times he's been there for his team and wonder why they left him. But then he'd turn that anger into motivation. He'd tell himself he doesn't need them and start working on his own skills even harder.
At first, he would be shocked and hurt. Naruto values his team highly. However, he has a strong will. So he would quickly turn his feelings into motivation. He could start exploring new places to gain more experience and knowledge. He might also try to understand why his team left him behind, and use that knowledge to better himself and his relationships with them.
One possible reason could be Naruto's over - eagerness to prove himself. Naruto is always trying to show that he's strong and capable, and sometimes this might come across as him not considering Sakura's feelings or opinions. For example, he might rush into a dangerous situation without consulting her, which could lead to an argument as Sakura is also a capable ninja who wants to be part of the decision - making process.
One reason could be to create shock value. By having two main characters kill another important character, it grabs the reader's attention. Another could be to explore a very dark and alternate version of the Naruto universe. Maybe the writer wants to show how far characters could be pushed in extreme situations.
In many Sakura Naruto fanfics, Sakura is often depicted as a strong - willed character. She uses her medical skills not only for healing but also for strategic purposes during battles.
There might be. The Naruto fan community is vast and diverse. Fanfic writers sometimes like to create alternative storylines for various reasons. Maybe they want to explore different character dynamics or add some drama. But this kind of plot goes against the typical perception of Sakura's character in the original Naruto story.
As he grows up, Naruto could become very angry. He might develop a sense of abandonment and this could fuel his determination to become stronger. He would want to prove himself to his mother, wherever she is. In this fanfiction, his anger could be a driving force in his character development.
