No. In the Naruto series, Naruto is the host of the Kyuubi, not its slave. Fanfics might deviate from the original concept, but in the official story, Naruto has a symbiotic relationship with the Kyuubi. He gains power from it and eventually befriends the Kyuubi spirit.
Well, generally his power would increase significantly. He'd likely have enhanced physical abilities like strength, speed, and stamina. His chakra reserves would also be much larger, allowing him to perform more powerful jutsus for a longer period without getting exhausted.
At first, Naruto might be overconfident with his reality - controlling power. He'd probably use it without thinking, like getting instant ramen whenever he wants. But as time goes on, he realizes the responsibility that comes with it. He starts to use it more carefully, for example, to heal the wounded or prevent natural disasters in the shinobi world.
One possible aspect could be a story about Naruto befriending the female Kyuubi. In many fanfics, they might start with Naruto trying to understand the Kyuubi's female form better. Maybe he discovers that she has a different personality compared to what he expected from the regular Kyuubi. For example, she could be more gentle and protective in a way that surprises Naruto.
Yes. In many Naruto fanfics, Kyuubi plays a significant role. Since it's so closely tied to Naruto, it can easily be made to serve the fanfic. It might be used to introduce new characters who are interested in the Kyuubi's power. Or perhaps the fanfic is set in a different timeline where the Kyuubi has a different relationship with Naruto and has to serve in a way to protect the village or Naruto himself.
In the naruto looks like kyuubi fanfic, a similarity could be in their expressions. When Naruto gets angry or is about to use his power, his facial expressions might mirror those of the Kyuubi. His eyes could narrow in a very fox - like way and his teeth might seem a bit more prominent, like the Kyuubi's fangs. Additionally, in terms of combat style, Naruto could incorporate some of the Kyuubi's natural instincts. For example, he might be more likely to attack from unexpected angles, just like a fox would when hunting.
Well, one key element is how Naruto acquires the ability to control sand. It could be through some ancient jutsu or a strange encounter. Another element is how he combines this new power with his existing skills. For example, using his shadow clone jutsu along with sand control.
Their relationship could also grow through mutual respect. The female Kyuubi respects Naruto's strength and determination, and Naruto respects her power and the fact that she has been trapped for so long. This respect can lead to a friendship or even something more as they rely on each other more and more in difficult situations.
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.
