It might suggest that Kyuubi is confused or surprised about something related to itself.
If Kyuubi says 'Who me?', it could potentially mean that it's either not expecting attention or is trying to play innocent in the fanfic. It could also be a moment of self-doubt for the powerful entity.
Well, when Kyuubi says 'Who me?', it could indicate that it's unsure of why it's being addressed or involved in a particular situation. Maybe it's questioning if it's the one expected to do or be something.
It could imply that in this fanfic, Naruto is made into a character who is a big fan of the marines. Maybe he admires their discipline, their sense of justice, or their military might.
It could be another powerful entity that is secretly manipulating the situation. Maybe there is a dark shinobi or a hidden organization that wants to see the Kyuubi and Naruto at odds. They could be the ones who set in motion the events that lead to Naruto scaring the Kyuubi. For example, they might have given Naruto a false power or false information that is causing the Kyuubi to be scared, all in an attempt to further their own evil plans. This entity would then be the main antagonist as they are the real source of the conflict.
The Akatsuki could still be the main antagonists. Even with Naruto's training by the Kyuubi, they would be after the tailed beasts. Their goals of collecting all the tailed beasts would put them in direct conflict with Naruto. And they have some really powerful members like Pain and Itachi.
The plot might involve Naruto entering the Kyuubi's mental space in a new and more powerful way. He could bring with him some sort of 'light' or positive energy that is anathema to the Kyuubi. This positive energy could represent all the good things in Naruto's life, like his friends, his dreams, and his love for the village. The Kyuubi, being a creature of darkness and power, is scared by this pure and positive force. Or maybe Naruto discovers a hidden weakness of the Kyuubi through his own growth and understanding. He then exploits this weakness, causing the Kyuubi to be afraid of what Naruto could do to it.
A 'naruto ganbanged kyuubi fanfic' could potentially be about Naruto and the Nine - Tails (Kyuubi) forming an unexpected and deep bond. Maybe Naruto discovers new powers within the Kyuubi that no one else knew about, and they work together to face new threats in the ninja world. This could involve Naruto learning to control the Kyuubi's power in a more refined way and using it to protect his village in unique ways.
It could be an original character created by the fanfiction author. This character might be a descendant of the original Kyuubi, but with a female form and her own distinct personality.
Well, if Naruto and Kyuubi fuse in a fanfic, one possibility is that Naruto gains an even greater boost in power. He might be able to access Kyuubi's chakra more freely and without the usual drawbacks. His physical abilities could skyrocket, like his speed and strength. Also, his appearance might change a bit, showing some characteristics of the Kyuubi, such as his eyes taking on a more fox - like look.
In the 'naruto banished kills the kyuubi fanfic', it might start with Naruto being wrongly accused and banished. As he's on his own, he starts to explore his relationship with the Kyuubi more deeply. He realizes that the only way to break free from the chains that the village's treatment has put on him is to defeat the Kyuubi. So, he uses his ninja skills, combined with some unexpected twists in his chakra control, to fight and kill the Kyuubi. This would completely change the Naruto universe as we know it, since the Kyuubi is such a fundamental part of the story.
Well, one possible plot twist could be that when Naruto consumes the Kyuubi's power, he doesn't gain full control immediately. Instead, he has to battle the Kyuubi's consciousness within his own mind. It could be like a mental tug - of - war where Naruto's will is tested against the Kyuubi's primal instincts. This would add a whole new layer of internal conflict to the story.
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.
