Well, Naruto is a really strong - willed character. So, at first he'd be really hurt. But then, he would probably try to figure out why his family has forgotten him. He might go on a journey to find answers, all the while dealing with the pain of this rejection. He could also be angry at his family for forgetting him so easily, especially considering all he's been through.
The 'naruto forgotten by family fanfic' might explore Naruto's emotional journey as he deals with being forgotten. He could start to question his identity and his place in the family. As he tries to get his family's attention back, he may discover secrets about his family that were previously hidden. He might also face challenges from those who don't want his family to remember him, and he would have to fight against them while also trying to re - establish his connection with his family.
One possible plot could be that Naruto, having reached the Jounin level, is suddenly shunned by his family. Maybe due to some false accusations or misunderstandings within the family. His family might cut off all communication with him, leaving Naruto to fend for himself while still carrying out his Jounin duties. He would have to struggle not only with the regular challenges of being a Jounin but also with the emotional pain of being forgotten by those he loves.
Maybe the main antagonist is a member of Naruto's own family who is power - hungry. This family member sees Naruto's growth to the Jounin level as a threat to their own position within the family. So, they manipulate the rest of the family into forgetting Naruto and excluding him from the family unit. They would stop at nothing to keep Naruto away and maintain their own power and influence.
One possible reason could be some kind of dark magic or jutsu that has affected his family's memories. Maybe an enemy cast a spell specifically to make his family forget about him to weaken him.
If the fanfic had a very niche concept or a plot that was a bit too different from the mainstream Naruto stories, it could have been forgotten. For example, if it focused on a minor character in a really unique way that not many people were interested in at the time. Also, if the website where it was hosted had some issues, like shutting down or losing data, that could contribute to it being forgotten.
In the 'naruto forgotten by family fanfiction', perhaps there's some kind of curse or misunderstanding that makes his family forget him. Naruto would then have to struggle not only with the normal challenges in the ninja world but also with the emotional pain of being forgotten by those who should love him the most. He may try different ways to make them remember, like showing great feats of strength or kindness, and along the way, he could make new friends who become like his new family.
I'm not sure specifically as there could be many different takes in such a fanfic. Generally, it might be about a character in the Naruto universe who is a prodigy but has been overlooked or forgotten. It could explore their journey to regain recognition, their unique abilities that were previously ignored, and how they interact with the well - known Naruto characters in new and unexpected ways.
Naruto may try to find out the reason why he is forgotten. He will start by reflecting on his own actions. Maybe he thinks he has done something wrong that made his family forget him.
