One possible plotline could be that they are forced into a situation where they have to be together, and over time, feelings develop and Sakura gets pregnant. Another could be a magical or alternate universe situation where their relationship is different from the original Naruto story, leading to her pregnancy.
Yes, there might be some. Some fanfiction writers may choose to explore the relationship between Madara and Sakura in a more innocent and family - friendly way, like focusing on their friendship or a non - romantic bond that could lead to an unexpected situation like Sakura being pregnant but in a very platonic or alternate universe context.
One interesting scenario could be that Madara and Sakura are in a parallel universe where the normal rules of their world don't apply. Here, their union and Sakura's pregnancy could be seen as a symbol of hope for uniting different clans. Another scenario could be that they are the only ones left after a great battle and Sakura's pregnancy represents the future of the shinobi world. They then have to find a way to raise the child in a desolate world while also rebuilding their society.
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.
There could be some out there. You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own. Look for tags related to Madara, Sakura, and pregnancy. However, the quality can vary greatly from one story to another.
One possible plot could be that they are in a world where enemies have become allies. Madara, with his powerful abilities, and Sakura, with her medical skills and strength, find themselves in a situation where they accidentally get closer and Sakura becomes pregnant. This could lead to a story of them trying to protect their unborn child from various threats in the shinobi world while also dealing with the shock and change in their relationship.
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.
Their relationship would likely become more protective. Madara, who was once a fearsome warrior, might soften and become extremely protective of Sakura and the unborn child. Sakura, on the other hand, would use her medical knowledge to ensure the health of the baby and also rely on Madara for emotional support in a different way than before.
One possible plot twist could be that the pregnancy is a result of some sort of ancient jutsu gone wrong. Maybe a forbidden technique that was meant to save Madara's life but instead had the side effect of causing Sakura to become pregnant. Another could be that an enemy has somehow manipulated their DNA to create the pregnancy as part of a grand scheme to control the two powerful shinobi.
