The baby might inherit Sasuke's brooding and determined nature. It could be very focused on achieving its goals, just like Sasuke was on his revenge mission. At the same time, from Sakura, it could get a sense of compassion. So it might be a complex character who is tough - minded but also caring towards others.
Well, perhaps the baby would be quite independent, much like Sasuke. However, it would also have Sakura's kindness. This combination could make it a bit of a loner at times, preferring to do things on its own, but also someone who is always ready to help those in need. It might be a bit reserved, not showing its emotions easily, but when it does, it's very sincere. For example, in a situation where a fellow ninja is injured, it would use its skills (inherited from Sakura) to heal them without hesitation, all while maintaining a somewhat aloof exterior.
Their baby's personality would be a blend. Naruto is known for his loyalty and his big heart. The baby would likely have that same loyalty towards its friends and family. Sakura is a hard - working and confident woman. The baby could inherit her confidence and work ethic. It might also have Naruto's sense of humor, always able to make others laugh. At the same time, it could have Sakura's focus, being able to concentrate on tasks at hand. Overall, it would be a complex personality with a mix of the best traits from both parents.
Sasuke becomes more gentle. Usually he is cold and aloof, but with baby Sakura, he has to be soft. He shows more patience as he takes care of her needs, like when she cries and he tries to figure out what's wrong.
His personality could be a blend of introversion and extroversion. In some situations, he would be like Sasuke, preferring to be alone and train or study. But when it comes to protecting his friends or family, he would show an extroverted side, being vocal and taking charge, much like Sakura when she is in a leadership role. He would also have a great respect for the ninja way, having been brought up hearing stories from his parents about their adventures and sacrifices.
One possible fanfiction could be about their baby inheriting Sasuke's Sharingan abilities. Maybe the baby shows early signs of these powers and Sakura has to figure out how to train the baby in both medical ninjutsu like her and also in the ways of the Uchiha clan. It could also show how Naruto interacts with the baby, being a close friend of Sasuke and Sakura. He might be like an uncle figure, teaching the baby some of his unique jutsu or life lessons.
In such a fanfiction, perhaps the story could focus on how Sakura and Sasuke adjust to parenthood. Maybe they face challenges like protecting their baby from old enemies who might target the new addition to the Uchiha family.
One possible reason could be her long - standing and deep - rooted love for Sasuke. Since childhood, she has had strong feelings for him. Maybe in this fanfiction, she realizes that her feelings for Sasuke are unshakable and that she can't continue to be with Naruto while having such intense feelings for another.
It could be very curious, a trait from both of them. Since Flynn is adventurous and Rapunzel was always eager to see the outside world. The baby might also be creative, perhaps having Rapunzel's talent for art or music.
She could be more nurturing. Since girls are often associated with nurturing qualities in many cultures, Sasuke as a girl might show more compassion towards her friends and comrades. Maybe she would be more in tune with her emotions and not suppress them as much as she did when she was portrayed as a male. This could lead to more complex emotional interactions with other characters.
One possible story could be that Sasuke returns to the village after his long journey. He and Sakura finally have time to be together. They discover they're going to have a baby. Sakura is both excited and a bit worried. Sasuke, though not very expressive, is secretly overjoyed. He becomes more protective of Sakura. As the pregnancy progresses, they start preparing a room for the baby. Sasuke might even go on small missions close to the village to get things for the baby.
One possible reason could be extreme jealousy. Sakura might be so blindly in love with Sasuke that she sees Naruto as a threat to Sasuke's attention or her relationship with Sasuke. Maybe she thinks Naruto is getting in the way of Sasuke's return to the village or her attempts to win Sasuke back.
