Maybe Madara trains Sakura in the art of stealth and assassination. He could teach her how to move silently, read an opponent's movements, and strike with deadly precision. This would be a departure from Sakura's usual role as a support and healer, and she could become a more well - rounded ninja. It could also lead to interesting interactions between her and her teammates when they see this new side of her.
One possible plot idea could be that Madara sees Sakura's potential in medical ninjutsu and trains her to combine it with combat in unique ways. For example, she could learn to use her medical chakra to enhance her physical attacks or to disrupt an opponent's chakra system more effectively during battle.
One idea could be that Genma is tasked with training Sakura in a special form of combat. He takes her to a secluded place and teaches her unique jutsu. Along the way, they face various challenges that test not only Sakura's physical skills but also her mental strength.
A third plot idea is that Madara is somehow cursed and Sakura, with her medical and combat skills, is the only one who can help him. In the process, they start to understand each other better. Madara discovers that there is more to the younger generation than he thought, and Sakura realizes that there is a depth to Madara that goes beyond his villainous reputation.
One plot idea could be that Madara, as a powerful vampire, saves Sakura from a group of dark vampires. He initially sees her as just a human to protect, but as they spend time together, he starts to develop feelings for her. Sakura, on the other hand, is intrigued by Madara's mysterious vampire world and wants to learn more. This could lead to a journey of discovery and love.
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.
The Akatsuki could be antagonists. They might see Sakura being trained by Madara as a threat to their plans. Since Madara has his own motives and is associated with the Akatsuki, they could fear that Sakura will become a powerful force against them if she is fully trained by him.
In some fanfictions, Madara trains Naruto in the art of swordsmanship. Since Madara was a formidable warrior, he could pass on his skills. Naruto, who is mainly known for his ninjutsu and taijutsu, might discover a whole new combat style under Madara's tutelage. This could lead to some epic battles where he surprises his enemies with his newfound skills.
Perhaps the fanfiction could center on the unborn child's potential power. Madara might worry about the child being used as a weapon or a tool by his enemies. There could also be a side plot about the reactions of the other ninja clans when they find out about Madara's pregnancy, and how it might change the power dynamics in the ninja world.
One idea could be that Jiraiya focuses on Naruto's rasengan training in a more extreme way. He takes Naruto to a secluded place full of natural challenges like strong water currents or rocky terrains. There, Naruto has to constantly adapt and use his rasengan in different situations to overcome obstacles. Another plot could involve Jiraiya teaching Naruto some secret clan jutsus that he discovered during his travels, which could give Naruto an edge in future battles. And also, Jiraiya could train Naruto in stealth and espionage skills, which are essential for a shinobi but Naruto hasn't had much focus on before.
One idea could be Hiruzen teaching Naruto some of the most secret and powerful jutsu in the village. For example, a special fire - style jutsu that was once used by the First Hokage. This would give Naruto an edge and also show the bond between him and Hiruzen. Another plot could be Hiruzen training Naruto in the art of political leadership. Since Naruto is destined to be a great leader, Hiruzen could impart his wisdom on how to handle different clans and political situations within the village.
