In a fanfiction, Madara might capture Sakura to gain leverage over Naruto. Since Sakura is one of Naruto's closest friends, Madara could think that by having her in his control, he can manipulate Naruto's actions. Sakura, being the strong - willed character she is, would surely try to find a way to escape and send a message to her friends.
If Madara captured Sakura in fanfiction, she could try to use her intelligence to outwit him. Sakura is not just a strong fighter but also a very smart character. She might pretend to cooperate with Madara while secretly gathering information about his plans and weaknesses.
In such fanfiction, Sakura might be depicted as more alluring and perhaps more bold in her interactions with Madara. Madara could be shown as having a certain charm that draws Sakura to him.
Well, it could be through his powerful ninja techniques. Maybe he uses his Sharingan to paralyze Sakura, or perhaps he physically restrains her with his great strength. In fanfictions, there are many creative ways for such a scenario to play out.
Perhaps he sees her as a threat. Sakura is a skilled kunoichi, and Madara may want to prevent her from interfering in his plans. So he restrains her to keep her out of the way.
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.
Since it's a fanfiction about Sakura being captured, it could have multiple interpretations. It could be that the capture is a plot device to explore Sakura's character more deeply. Maybe she's captured by a powerful villain who wants to use her skills for their own ends. Or it could be a more psychological capture, like being trapped in a false reality. Fanfiction often takes the basic elements of a character and creates unique and unexpected stories around them.
If Naruto is captured by Madara in a fanfiction, it could also explore Naruto's internal struggle. He might start to question his own power and abilities since he was caught by such a powerful enemy. On the other hand, Madara might use this opportunity to study the Nine - Tails' chakra within Naruto more closely. This could potentially lead to some new and unexpected developments in the story, like a new form of the Nine - Tails chakra being unlocked due to Madara's interference.
Sakura would probably be angry at herself for being captured. She's a proud ninja. So she would start looking for weaknesses in Itachi's hold on her. Maybe she would try to engage him in conversation to find out his motives, all the while formulating a plan to break free. She could also try to send out some sort of signal to her comrades if possible.
One common theme is redemption. Madara, having made many wrong choices in his life, often finds redemption through his interactions with Sakura. For example, in some fics, Sakura's kind heart makes Madara re - evaluate his actions.
