One consequence could be that he becomes extremely powerful. His physical abilities like strength, speed, and endurance are enhanced. He can also use more powerful jutsus with the extra chakra boost from the Kyuubi.
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.
One common plotline is the Kyuubi teaching Naruto new and powerful jutsu. Since the Kyuubi has a vast amount of chakra and knowledge, it could share unique techniques with Naruto that are not part of the regular ninja training. Another plotline could be the Kyuubi's influence on Naruto's relationships. For example, some fanfictions explore how Naruto's connection with the Kyuubi affects how his friends and villagers perceive him. It can also lead to some interesting character development as Naruto has to learn to control the Kyuubi's power without being consumed by it.
Well, in Naruto fanfiction, the Kyuubi often has the power of destruction. It can unleash huge amounts of raw chakra that can level mountains or create massive shockwaves. The Kyuubi's power can also be used for healing in some fanfictions. Since it has such a large amount of chakra, it can be used to heal the jinchuriki's wounds, even from near - fatal injuries. Also, in certain fan - made stories, the Kyuubi has the ability to communicate telepathically with the jinchuriki, providing wisdom and knowledge from its long existence.
It could be in an alternate universe fanfic where the rules of the Naruto world are completely rewritten and Naruto's identity as the kyuubi is central to a new and unique storyline.
In Naruto fanfiction, 'naruto dominates kyuubi' can be significant as it shows Naruto's growth and power. Naruto has a complex relationship with the Kyuubi. By dominating it, he is taking control of a powerful and previously menacing force within him. It could symbolize his journey towards becoming a stronger shinobi and his ability to use the Kyuubi's power for good, rather than being controlled by it.
Maybe it's because Naruto has some sort of special connection or resemblance to the Kyuubi that Kushina notices. For example, Naruto might display some of the Kyuubi's power characteristics in an obvious way that makes Kushina jump to that conclusion.
At first, Naruto might see the Kyuubi as just a source of power. But as he starts to protect it, he realizes it's more of a partner. Their relationship evolves from a simple user - power source dynamic to a deep - seated friendship. He begins to understand the Kyuubi's emotions and past, which further cements their bond.
Sasuke is often a popular character in these fanfictions. His relationship with Naruto can be further explored in the context of the Kyuubi's fatherly influence. Maybe Sasuke is initially skeptical of this new - found bond between Naruto and the Kyuubi but later comes to accept it. Sakura is also a common character. She might notice the changes in Naruto due to the Kyuubi's fatherly presence and be either supportive or a bit jealous. Kakashi could also be there. He might be observing Naruto's growth under the Kyuubi's guidance and offer his own wisdom as Naruto's former teacher.
