What are the possible themes in a 'Naruto is pregnant by Kakashi' fanfiction?

Well, there could be. Fanfiction writers love to explore unique and unexpected relationships. Since Naruto and Kakashi are both popular characters in the Naruto universe, some writers might come up with such a plot for the sake of creativity and exploring different storylines. But it's not a part of the official Naruto story.

One common theme is the exploration of how the characters' relationships change. For example, how Kakashi might become more protective of fem Naruto during her pregnancy. Another theme could be the challenges they face in a world where pregnancy might be unexpected or difficult given their ninja lifestyles.

One possible theme could be the exploration of forbidden or taboo relationships. Since this scenario is so far from the original Naruto story, it would likely touch on the idea of breaking boundaries and norms within the Naruto universe. Another theme might be the struggle of Naruto dealing with this unexpected and unorthodox situation, both physically and emotionally.

One possible motive could be to help Naruto control the Nine - Tails' chakra better. Hypnosis might be a way to reach into Naruto's subconscious and find a way to coexist with the powerful force inside him.

One possible reason could be that Kakashi is preoccupied with other important matters in the village. Maybe he has some top - secret missions or tasks assigned by the Hokage that demand his full attention, leaving him with little time to focus on Naruto.

One reason could be that he sees Naruto as a younger version of himself in some ways. Both have had their share of loneliness and challenges growing up. Kakashi may want to prevent Naruto from going through the same pain he did. Another reason is Naruto's importance to the village. As the jinchuriki of the Nine - Tails, Naruto is a key asset. Kakashi, being a loyal ninja, wants to protect the village's future which is tied to Naruto.

One possible reason could be that Naruto might feel Kakashi is too strict with his training. Maybe Kakashi's methods are too harsh for Naruto, making him frustrated and gradually developing dislike.

One possible reason could be Kakashi's reputation as a strict and powerful teacher. Naruto might be in awe of his skills and fear making mistakes in front of him.

One possible reason could be that Naruto might be trying to prove his independence. He has grown and wants to show that he can handle things on his own without always relying on Kakashi's guidance.

One plotline could be that they face difficulties during the pregnancy due to their ninja duties. Maybe they have to hide their pregnancy from enemies or deal with the physical strain of being a ninja while pregnant.
