Well, the plot might develop with Sakura being hunted by ninja clans who fear the return of Madara through her. She could then go on a journey to find out more about her reincarnation status. Along the way, she might discover some long - lost jutsu that Madara was known for. She could also form an unlikely alliance with some of Madara's old comrades or enemies in the fanfic. And as she delves deeper into her new identity, she might have to make some tough choices between her old self and this new 'Madara - influenced' self.
A possible plot development could be that Sakura's friends initially reject her when they find out about her being Madara's reincarnation. But as she starts to show that she's still the same Sakura in some ways, they gradually come to accept her again. She could also use her newfound connection to Madara to try and prevent a new war that's brewing in the fanfic world. Maybe she has to battle some dark forces that are trying to use her reincarnation for their own evil purposes. There could be a lot of internal struggle within Sakura as she tries to balance her normal self with this new identity thrust upon her.
In most fanfictions, the evidence is often created within the unique narrative of the story. Maybe it could be things like similar chakra signatures, or shared memories in a dream - like state. However, in the original Naruto canon, there is no such connection, so it's all fictional speculation within the fanfiction.
One possible plot development could be that after saving Naruto, Madara tries to mentor him. He sees Naruto's potential and wants to shape him into an even greater ninja, sharing his own knowledge and skills that have been honed over years.
In many fanfictions, the idea of Sakura being the reincarnation of Madara is used as a plot device. This can lead to some really interesting story developments. For example, it might change how Sakura interacts with other characters like Naruto and Sasuke. Her new 'reincarnation' status could give her access to Madara's powers or knowledge in some way. It also allows the author to play with themes of destiny, power, and self - discovery in a different way compared to the original Naruto story.
There could be implications for the overall plot of the fanfiction. It could lead to a different kind of conflict, perhaps with other characters who have a vendetta against Madara or the Uchiha clan. Sakura's new identity as the reincarnation of Madara could also attract the attention of powerful and dangerous entities, forcing her to face new challenges and make difficult choices that she wouldn't have had to in the original Naruto story.
Well, a plot could develop where Naruto is trained in secret by an old ally of Madara and Hashirama who knows about his heritage. This training could involve unlocking ancient jutsu that were lost over time. Also, his relationships with other characters like Sakura and Kakashi would change as they try to come to terms with his new - found family background. And there could be a conflict with the Akatsuki, who might see Naruto as an even greater threat or a valuable asset because of his relation to Madara and Hashirama.
One possible plot development could be that Sakura has an innate talent for interrogation, inherited from Ibiki. This could lead to her getting involved in more espionage - related missions in the fanfiction.
One challenge is to make their relationship believable. Madara is from a different era and has very different values compared to Sakura. Another is to balance their power levels. Madara is extremely powerful, and Sakura, while strong, is not on the same level. So, it's hard to create scenarios where she can hold her own against him without making it seem unrealistic. Also, staying true to their original characters can be difficult when creating new situations for them in the fanfiction.
One possible plot could be Sakura ending up in the Pokemon world and becoming a Pokemon trainer. She might use her medical knowledge from Naruto to take care of injured Pokemon. For example, she could set up a sort of Pokemon clinic.
One idea could be a time - travel plot where Sakura is sent back in time and meets Madara. She tries to change his path of destruction. Another could be a scenario where Madara is resurrected in Sakura's time and they have to team up against a new common enemy. Maybe a plot where Madara, in his search for power, discovers Sakura's unique medical and combat abilities and tries to use her for his own gain.
Well, a plot could involve Sakura and Madara being forced to team up against a new, powerful enemy that threatens the entire ninja world. Sakura initially distrusts Madara, but as they fight side by side, she begins to see a different side of him. Maybe there's a plot where Madara is cursed, and Sakura is the only one who can break the curse because of her unique chakra. As she tries to break the curse, they get to know each other better. Or perhaps in a parallel universe, Sakura and Madara are lovers from the start and they have to fight against the forces that want to tear them apart.
