It could be the same antagonists from the original Naruto series who were involved in the events that led to his family's misfortune. For example, Orochimaru might be one of the main antagonists as he was always after power and could have been involved in something related to Naruto's family.
One interesting plot point could be Naruto using his knowledge from the future to outwit his enemies more easily in the past while on the mission to rescue his family. For example, he might know the weaknesses of certain villains he didn't before.
In these types of fanfics, Naruto's time travel can be a very interesting plot device. When he is neglected by his family in the original timeline, going back in time gives him a chance to rewrite his story. He could use his skills and knowledge to confront his family about their neglect. Sometimes, he may even find out the reasons behind their behavior in the past. It's a great way to explore different aspects of Naruto's character and the Naruto universe in a new and exciting way. And again, the best way to find these fanfics is to search on the major fanfic platforms and engage with the Naruto fan community.
One common plotline is that Naruto uses his knowledge from the future to gain power quickly in the past. For example, he might already know some powerful jutsu and train himself to master them earlier. Another is that he tries to make his family notice him and regret their previous neglect. He could also change the course of events in the village to make it a better place sooner.
Well, it could be a combination of things. Maybe he saw through some hidden agendas of the village elders or was constantly overlooked for important missions despite his skills. Maybe there were trust issues with his teammates or mentors that built up over time and caused this hatred.
One great 'Naruto Time Travel Fanfic' is 'A New Chance at Life'. It has an interesting plot where Naruto goes back in time and tries to change things for the better. The character development is really well - done in this fic.
I really like 'Time - Twisted Naruto'. In this fanfic, Naruto goes back to his younger self's body. It's cool because he gets to use his future skills and knowledge right from the start. It also has some great fight scenes that are different from the original Naruto series as he uses his new - found advantage in unexpected ways.
In 'naruto and his family fanfic', a frequent theme is identity. Naruto's children, for example, have to come to terms with being part of the Uzumaki family. Another theme is the importance of home. The family's home in Konoha is often a central element, representing safety and stability. Additionally, the theme of unity is common. The family sticks together through thick and thin, much like Naruto united the ninja world in the original series.
Naruto might initially be heartbroken. He's a character who values family and connection deeply, so rejection would hit him hard. He could go into a state of self - doubt, wondering what's wrong with him.
Naruto could try to communicate. He could sit down with his family members and try to understand why they hate him and also explain his side of the story.
