If Tsunade adopted baby Naruto in fanfiction, it would greatly impact the story. Naruto would grow up with a better understanding of the importance of self - control, as Tsunade is known for her strong will. The relationship between the Leaf Village and other villages might also be affected. Tsunade could use Naruto as a symbol of the village's new beginning, leading to more diplomatic relations. Additionally, Naruto's training would be more focused on a combination of combat and medical ninjutsu, creating a more versatile ninja.
In the fanfiction world where Tsunade adopts baby Naruto, the Naruto universe would change significantly. Firstly, Naruto's upbringing would be more stable and he would likely have better access to resources and training. Tsunade's influence would mean Naruto has a more strategic approach to being a ninja. He would also be more aware of the sacrifices that come with being a shinobi from an early age. Politically, Tsunade could use Naruto to bridge gaps between different factions within the village. This would create a more united and powerful Leaf Village in the long run.
At first, their relationship would be very awkward. Naruto would be a bit shy and Tsunade might be stern. But as they get to know each other better, they could become friends. Eventually, they might develop romantic feelings. For example, Naruto could start to admire Tsunade's leadership skills and Tsunade could be impressed by Naruto's growth.
The relationship would become extremely complex. Naruto, who respects Tsunade deeply, would be uncomfortable with the power dynamic. He would constantly try to find a balance between respecting her as a person and fulfilling whatever the 'slave' situation entails. Tsunade, on the other hand, would be in a position of having to follow Naruto's commands, which would be a huge shift from her normal authoritative role.
His relationship with Sasuke would be different. Since Naruto would have a more stable upbringing, he might approach Sasuke with more understanding and less of the desperate need to bring him back. His friends in Konoha would also see him in a new light, as he is now under the care of two very respected shinobi. And his relationship with the village elders might be less strained, as Tsunade could act as a buffer.
His personality might be more reserved. Tsunade is not as boisterous as some of Naruto's other mentors. So he could be less likely to jump into things without thinking. For instance, he might analyze a situation more carefully before acting.
The power dynamics could shift. In fanfiction, new powers could be introduced to Naruto, making him even more powerful. This would change how he is perceived in the Naruto universe and how he interacts with other characters like Sasuke and Sakura.
The power balance would be greatly affected. If fanfiction gives Naruto some overpowered abilities like instant teleportation across any distance, it would make many of his battles much easier. Enemies that were once a threat would no longer be so.
In the beginning, Tsunade's relationship with baby Naruto could be based on her sense of duty as a village leader and a healer. However, as she spends more time with him, she discovers his unique charm. Naruto's innocent nature and his unwavering spirit would start to break down Tsunade's tough exterior. She would gradually open up to him, sharing her own experiences and wisdom. Naruto, being a baby, would soak up all this attention and care, and as he grows, he would repay her kindness with loyalty and love. This would lead to a deep - seated relationship that is part family - like, part mentor - mentee, and would be crucial for Naruto's growth as a ninja and a person.
Naruto would become more introspective. He has to understand his new role as the father of the universe. His relationships with others would change too. He might distance himself from his old friends in some ways as he tries to figure out his new place in the cosmos. His ninja skills would also be adapted to the cosmic environment. For example, his shadow clones could be used to explore different parts of the universe simultaneously. He would be constantly learning about the vastness of the universe and how to best care for it.
It could change the political landscape. If Shizuka is from a powerful family or village, the alliance through their marriage could strengthen Konoha's position. For example, in times of war, they could use the combined resources more effectively.
In this fanfiction, their relationship would be transformed. They would be like a married couple in a way, but without the formalities. Jiraiya would probably tone down his womanizing ways as he has a family to think about now. Tsunade would be more open and less prickly around Jiraiya. They would bicker less and cooperate more. Their relationship would be centered around Naruto, and as he grows, they would grow together as a family unit, with their bond getting stronger over time.
