Tsunade's character might develop by becoming more maternal towards Naruto. Saving him could make her see him as more than just a village ninja. She could start to care for him in a more personal way, like a mother figure.
She might become more fearless. Rescuing baby Naruto could put her in a dangerous situation, but coming out of it successfully could boost her confidence. She may start taking more risks in battles and leadership decisions, knowing that she has a responsibility to Naruto now.
Tsunade's character often develops a stronger sense of purpose. In fanfictions where she finds baby Naruto, she realizes that she has a new mission, which is to raise Naruto to be a great ninja. This might lead to her changing her ways in terms of leadership in the village. She might start to focus more on the future generation and how to make the village a better place for Naruto and others to grow up in. She also may become more empathetic towards others in the village as she experiences the joys and challenges of raising Naruto.
In many fanfictions, Naruto's determination and positive attitude start to rub off on Tsunade. She has been through a lot and is a bit jaded, but Naruto's energy makes her feel alive again. This new - found connection leads to a budding romantic relationship. For example, Naruto might bring her small gifts from his travels, which are simple but meaningful gestures that slowly warm Tsunade's heart.
Naruto's understanding of sacrifice could deepen. If he has to put himself in great danger to save Tsunade, he'll learn more about what it means to sacrifice for others. He might recall the sacrifices of his predecessors like the Hokages and use that as motivation to keep going, even when the odds are against him.
The story could develop with other characters getting involved. For example, Sasuke might hear about what happened and come back to the village to confront Tsunade. This would create a lot of tension and drama in the fanfiction.
Well, it could develop through shared experiences. For instance, if they both go on a diplomatic mission to another village. During the journey, they face difficulties like hostile ninja attacks or harsh weather. They have to rely on each other's skills. Naruto's combat skills and Tsunade's strategic thinking complement each other. This cooperation makes them closer and over time, love might bloom between them.
If Tsunade kisses Naruto, it could strengthen their relationship in a mentor - like way. Naruto might see it as a sign of deep respect and trust from Tsunade. He would likely feel more confident in following her guidance. For Tsunade, it could be a way of showing her pride in Naruto's growth.
In fanfiction, if Tsunade discovers Naruto, she could enlist his help in some of her projects. For instance, if she is working on improving the village's medical facilities, Naruto could use his strength and determination to assist. This would not only strengthen their relationship but also give Naruto a new sense of purpose. He could learn about the importance of non - combat aspects of being a ninja, like helping the community. And this new experience could shape his character in different ways compared to the original story.
Naruto may also develop a darker side to his personality. The abandonment could make him feel betrayed and angry. He might struggle with controlling his emotions, especially his anger. However, this could also lead to him learning how to channel that anger into power in a more controlled manner, like he did with the Nine - Tails' chakra, but in a more refined way.
His character could become more self - assured. Tsunade's belief in him would boost his confidence further. He might become more strategic in combat, learning from Tsunade's battle - hardened experience.
