In Naruto family betrayal fanfiction, the Uchiha family is often at the center. Itachi's relationship with his family can be twisted in different ways. Maybe Sasuke discovers that Itachi was actually planning a full - scale betrayal all along. Then there's the Inuzuka family. Kiba's family members could be involved, like if his mother or father were secretly working for an enemy and had to betray their family to keep their cover. And the Yamanaka family as well. Ino's father could be a character in a plot where he betrays the family due to some political intrigue within the Hidden Leaf Village.
Naruto himself could be a victim of family betrayal. His father Minato or mother Kushina might be involved in some alternate - universe plot where they turn against him for some dark reason. Sasuke's family is also a likely candidate. Itachi's actions could be re - imagined in a way where his real motives are more about betrayal of the Uchiha family rather than protecting it. And Hinata's family might be involved too, like if Neji, before his death, was made to betray the Hyuga family in some fan - created scenario.
Snape is a likely candidate. In the original series, his loyalties were always a bit of a mystery at first. In fanfiction, he could be further explored in terms of false betrayals or real ones. Another one could be Draco Malfoy. He was on the verge of becoming a full - blown Death Eater in the original, so in fanfiction, he could either truly betray his Hogwarts classmates or be wrongly accused of betrayal.
The village elders are often depicted as the ones involved in Naruto's betrayal. They might see him as a threat to their power or the stability of the village. Also, some fanfictions might involve Danzo. He has always been a bit of a shadowy figure in the Naruto series, and his underhanded ways could easily be written into a plot where he is behind Naruto's false accusations and subsequent banishment.
Peter Pettigrew is a very likely character to be involved in more acts of betrayal in fanfictions. Since he already betrayed James and Lily Potter in the original story, it's easy to imagine him continuing his traitorous ways. Another could be Draco Malfoy. In some fanfictions, he might be made to do more extreme acts of betrayal rather than just being a bully. He could be forced to betray his schoolmates in a more serious way for the sake of his family's safety.
Cedric Diggory could be an unexpected character in a betrayal scenario in fanfiction. Maybe in an alternate version, he becomes jealous of Harry's fame from being in the Triwizard Tournament and betrays him. This could be a really interesting twist as Cedric is generally seen as a good and honorable character in the original story.
Naruto is the central figure in this 'naruto imprisoned by his family fanfiction'. His family, including Minato and Kushina, are likely to be directly involved in his imprisonment. However, other characters from the Naruto universe might also play a role. For instance, Jiraiya could be a character who tries to find out why Naruto has been imprisoned and works towards his release. Also, Sasuke might get wind of Naruto's situation and decide to take action, either to help or because he sees it as an opportunity to gain an advantage.
Obviously Naruto himself. Then his parents, Minato and Kushina. His wife Hinata and their children would also be part of it. Jiraiya could also be involved as he was like a father figure to Naruto. And maybe some of the remaining Uzumaki clan members if they are still alive in the fanfiction. Also, characters like Iruka, who was an important person in Naruto's early life, could be there to witness the family reunion.
Sasuke is a likely candidate in some fanfictions. Given their complex relationship throughout the original series, it's easy to imagine a scenario where Sasuke's thirst for power or some misinformation leads him to betray Naruto. Another could be Sakura. If she becomes jealous of Naruto's growing power or if she's manipulated by outside forces, she might turn against him.
There could be new characters specific to the village where he becomes Kamikage. For example, some powerful shinobi clans within that village. Their leaders would be important as they could be Naruto's allies or opponents. Also, the previous Kamikage's advisors might still be around and play a role in guiding or challenging Naruto. Maybe an old sage - like figure who has deep knowledge of the village's secrets and helps Naruto understand and respect the village's heritage.
Well, Ares could be involved. He has had his clashes with Percy in the original stories. In fanfiction, his war - like nature and desire for chaos could make him set up Percy to look like he's betrayed the community. Also, Octavian from the Roman side might be a character in such a scenario. He's power - hungry and jealous of Percy's status. He could spread false rumors or create situations that make it seem as if Percy has betrayed the Roman demigod community.
In some more creative fanfictions, even characters like Kakashi could be made to betray Naruto. Maybe he is put under a powerful genjutsu that makes him see Naruto as an enemy, or he is forced to choose between the village's interests (as misinterpreted by some) and Naruto, and unfortunately chooses the wrong side. However, this would be a more out - of - the - box scenario compared to the more common ones.
