I think all three are great in their own ways. Naruto is the heart of the story, his optimism and determination are infectious. Sakura has the potential to be a complex and strong female character. She can have her own character arc that is independent yet related to Naruto and Tsunade. Tsunade, with her long history and powerful abilities, can be a source of both conflict and resolution in the fanfictions. For example, her past experiences can create interesting plot twists when combined with the current situations of Sakura and Naruto.
For Naruto, he could develop by learning more about leadership from Tsunade. He already has his own unique style, but Tsunade's wisdom in leading the village could give him new insights. Sakura could develop her medical ninjutsu further under Tsunade's guidance and also become more confident in her combat abilities. Tsunade herself could develop by seeing the new generation, Naruto and Sakura, grow and be inspired to take on new challenges for the village.
Well, Naruto himself could be involved. He might be concerned about Tsunade's pregnancy and offer his support in some way, like running errands for her or helping to keep the village in order while she's dealing with her pregnancy.
It's Naruto and Tsunade. Naruto is known for his determination and his ability to make friends and influence those around him. Tsunade, on the other hand, is a strong - willed woman with great medical and combat skills. In this fanfiction, their interactions are likely to be the focus, with Naruto looking up to Tsunade as a mentor and Tsunade seeing Naruto as a symbol of hope for the future of the village.
There might be a fanfiction where they are all involved in a medical emergency. Since Tsunade is a great medical ninja and Sakura is her apprentice, and Naruto is always in the thick of things. They have to work together to save a village from a mysterious illness. It would be full of drama and moments of them relying on each other's skills.
The plot could involve a mystery in the village. Strange things start happening, and Naruto, Sakura, and Tsunade have to work together to solve it. Along the way, they face various challenges, and their individual skills and teamwork are put to the test. They also learn more about each other's pasts and how it relates to the current mystery.
One great 'Naruto and Tsunade Fanfiction' is 'The Mentor and the Student'. It explores Tsunade's role in Naruto's growth further. It shows how she not only teaches him medical ninjutsu but also imparts wisdom about leadership. Another one could be 'A Different Bond' which delves into their relationship in a more emotional way, showing how they support each other through tough times in the village. There's also 'Naruto and Tsunade: The Unseen Alliance' which creates unique adventures for them that are not part of the original storyline.
One great Sakura Tsunade fanfic is 'The Healer's Legacy'. It shows how Tsunade trains Sakura to be an even better medical ninja. Another is 'Sakura's Mentor', which focuses on their day - to - day interactions during Sakura's training. 'Tsunade's Apprentice' is also worth reading as it delves deep into Sakura's growth under Tsunade's wing.
I would recommend 'Tsunade's Legacy: Sakura's Growth'. It beautifully portrays how Sakura evolves under Tsunade's guidance. It has great action scenes and also some heart - warming moments between the two.
Sakura might support Naruto. Despite the exile, she could believe in his innocence and try to find ways to help him. Also, Kakashi, who has always had a connection with Naruto, would be likely to support him. He might secretly provide Naruto with some resources or training advice.
Sasuke would be a great secondary character. His complex relationship with Naruto and Sakura could add a lot of drama. Kakashi too, as he can be a mentor figure to them. And Shikamaru, with his intelligence, can help them out in difficult situations.
