Well, Naruto has always been a fighter. In this situation, he might start to explore his own unique abilities more deeply. He could go on solo missions to prove his capabilities. Also, he might look for a mentor figure other than those in his immediate family. For example, he could turn to Kakashi for more guidance and training. By doing these things, he gradually shows that he is not someone to be neglected.
Perhaps there are family secrets or misunderstandings. His family might have some hidden agenda or past issues related to Naruto's brother that make them focus more on him. It could also be that Naruto's brother is seen as more compliant with the family's traditions and expectations, while Naruto is more of a free - spirit, which causes the neglect.
In these fanfictions, a common theme is Naruto's relationship with his friends. Given the neglect at home, his friends become even more important. They might be the ones to support him through his difficult times. Also, there could be a theme of Naruto learning to forgive his brother. This could involve a lot of inner - conflict as he has to deal with his hurt feelings while also trying to understand his brother's situation. It's often a complex exploration of family dynamics and personal growth.
Maybe the brother is seen as more obedient and studious. In a ninja village, those traits are often highly valued. Naruto, on the other hand, is very boisterous and doesn't always follow the rules. So, in the fanfic, the family or those around them might give more attention to the brother. Also, it could be that there's some sort of prophecy or family legacy associated with the brother that overshadows Naruto, causing the neglect.
One possible fanfiction could be where Naruto is somehow transported to the world of Rias. Her brother, perhaps being caught up in his own duties and status, neglects Naruto. Naruto, used to being an outcast in his own village at times, initially feels a sense of deja vu. But as the story progresses, he shows his strength and determination, which gradually makes Rias's brother take notice and start to regret his neglect.
Well, it could make him more desperate to catch up. He might become more self - doubting at first. But then, as he realizes his mistake, he could develop a stronger sense of determination to overcome his lack of training. For example, he might start training in more unorthodox ways to make up for lost time.
One possible story could be that Naruto discovers his unique bloodline abilities later in life and realizes that his parents' neglect was partly due to fearing his power. He then has to come to terms with this and learn to control his abilities on his own.
He might try to prove himself. Naruto has always been a determined character. He could focus on his ninja training more intently, aiming to show everyone his worth despite being neglected. Maybe he'd also start to distance himself a bit from his family situation and form closer bonds with his friends like Sasuke and Sakura, who might understand and support him through this tough time.
He might try to prove himself. Naruto has always been a determined character. So, he would likely focus on his training more, aiming to show his worth to those who neglect him. For example, he could strive to become a stronger ninja faster than his siblings, in the hope that his efforts would be noticed and the neglect would stop.
He might focus on his training more. By pouring all his energy into getting stronger, he can distract himself from the pain of family neglect. For example, he could spend long hours practicing new jutsu or improving his physical abilities.
