One key moment could be when Naruto gets seriously injured and Tsunade heals him with great care, showing her motherly love. Another might be when Tsunade gives Naruto some important advice about handling political situations in the village, like a mother guiding her son. And also, when Naruto defends Tsunade against someone who disrespects her, showing his loyalty as a son would to his mother.
Well, it could make Naruto more confident. Having Tsunade as a mother - figure gives him a sense of stability. He might grow to be more empathetic as he experiences a different kind of family bond. Tsunade's tough - love approach could also toughen Naruto up further and teach him more about leadership and responsibility.
In such fanfictions, the relationship between Naruto and Kyuubi can be developed in various ways. For example, the Kyuubi could start teaching Naruto about his heritage in a more motherly way, like sharing stories of the Uzumaki clan. Naruto, on the other hand, could show his loyalty and love towards the Kyuubi as he would to a mother. This could also impact his relationships with other characters. His friends might be initially confused but later come to understand and support this new relationship of Naruto's.
She might be initially shocked. Given her own past traumas and her relationship with Naruto, she could be hesitant at first. But then, considering Naruto's lonely situation, she might warm up to the idea and show a more maternal side towards him.
Well, in this fanfiction scenario, if Naruto discovers Tsunade is his mother, it could change his entire world view. He has always seen Tsunade as a strong and somewhat intimidating figure in the village. Now, as his mother, she could become a more nurturing presence. Naruto might also start to question his own identity more deeply. He's used to being the orphaned Naruto, but now he has a family connection to one of the most powerful people in the village. This could lead to new storylines about him learning more about his family history and what it means to be related to Tsunade.
If Tsunade was Naruto's mother in fanfiction, his childhood could have been filled with more discipline. Tsunade is a strict person when it comes to certain things. She would have made sure Naruto studied and trained properly. However, she would also have shown him great love and care. Maybe she would have taken Naruto on trips around the village and told him stories about the old days, which would have given Naruto a greater sense of belonging.
Naruto might be longing for a motherly figure in his life. He has always been alone and has seen how others have mothers. Tsunade, being a strong and caring woman in the village, could be someone he looks up to and wishes to have as a mother.
A frequent trope is the emotional bond between them. Naruto might seek comfort from the Kyuubi during tough times, and the Kyuubi would be there for him. There could also be a trope where Naruto tries to make the Kyuubi proud, similar to a child trying to impress their mother. He would constantly strive to become stronger and better at using the Kyuubi's power in a positive way.
Well, if Tsunade were Naruto's mother in fanfiction, it would likely change the story a great deal. For one, Naruto might have had a more stable upbringing in the village. Tsunade could have protected him from some of the early hardships he faced, like being ostracized for having the Nine - Tails. Also, Naruto might have learned medical ninjutsu much earlier from Tsunade, which could have added a new dimension to his fighting style. And perhaps he would have had a more confident personality from the start, since Tsunade is a strong - willed and confident character herself.
In fanfiction, Naruto might show his love for his mother through his memories. He could constantly recall the little time he had with her. For example, he might remember any advice or lullabies she gave him. These memories could fuel his actions, like when he faces difficulties, he might think about how his mother would want him to be strong and persevere.
