Yes, in the vast world of fanfiction, there are some really out - there concepts. There could very well be such a fanfiction exploring this highly unusual and creative scenario. However, it would likely be a very niche and perhaps controversial piece due to the nature of the concept. It might involve a lot of creative license in terms of how the pregnancy could even be possible in the Naruto universe's lore and mechanics.
In fanfiction, such a concept could lead to an interesting story. The baby might inherit Naruto's determination and the Kyuubi's power. It could be a powerful force for good in the Naruto universe, perhaps having unique abilities that no one has seen before. Maybe the baby would have to learn to control its power from a young age, just like Naruto did with the Kyuubi's chakra.
One main theme is the relationship between the innocent and vulnerable baby Naruto and the powerful, yet somewhat trapped Kyuubi. It shows how two very different entities co - exist.
One consequence could be that Naruto grows up with an even stronger connection to the Kyuubi's power from a very young age. This might make him a much more powerful ninja earlier on in his life.
There is a fanfiction where Naruto as a baby has some really cute interactions with the Kyuubi's consciousness. It's a heart - warming story that explores how the Kyuubi might have different feelings towards a baby Naruto compared to the older Naruto. It delves into the idea that the Kyuubi, despite being a powerful and often feared entity, has a sort of soft spot for the innocent baby Naruto.
The baby could be a symbol of a new era in the Naruto fanfiction world. It might have the ability to communicate with all tailed beasts easily, given its unique parentage. This would give it a great advantage in resolving conflicts between different factions.
There's no way for me to tell who the author is just from the title 'kyuubi baby a naruto fanfic'. It could be someone who is really passionate about Naruto and the concept of the Kyuubi in a different form. To find the author, you might want to check popular Naruto fanfic archives or forums where fans discuss and share fanfics like this one.
I'm not sure specifically as I haven't read it. But generally, a Naruto fanfic with 'Kyuubi baby' in the title might be about the nine - tailed fox (Kyuubi) in some form of a baby or new - born state within the Naruto universe. It could involve how this Kyuubi baby affects the story, the characters like Naruto who has a connection to the Kyuubi, and perhaps new adventures or relationships that form because of it.
Often, the relationship development begins with Kyuubi being a menacing presence in Naruto's mind. However, as time passes, Naruto's determination and the fact that he is just a baby stir something in Kyuubi. Kyuubi might start to see Naruto as a potential ally or even a friend in the long run. Maybe there are times when Naruto is in distress, like when he is ill or being bullied in the orphanage, and Kyuubi unconsciously sends some of its warm chakra to comfort Naruto. This act of kindness, even if it's involuntary at first, starts to change the dynamic between them.
A 'naruto is pregnant with kyuubi's baby' fanfiction would probably be a wild ride. It could start with some sort of strange event that leads to this situation, like a powerful jutsu gone wrong or a mysterious prophecy. As the story progresses, Naruto would have to come to terms with his new state. The other characters like Sasuke, Sakura, and Kakashi would have their own reactions, some might be supportive while others would be horrified. The story could also touch on how the baby might change the balance of power in the Naruto universe, whether it would be a force for good or something more dangerous.
