Obviously, the kyuubi itself is the central character. But there could also be characters like the shinobi who are either trying to control the kyuubi's new power or are afraid of it. Maybe there's a young and brave ninja who wants to befriend the kyuubi and help it use its power for good.
One possible plot could be that the kyuubi discovers a hidden ancient power source. Maybe it's a long - forgotten magic crystal or a special energy field. This new power source could enhance its existing abilities, like making its fire attacks more intense or its speed much faster.
In some fanfictions, the Kyuubi's power could be depicted as more spiritual. Instead of just raw chakra, it could have elements of ancient wisdom and spiritual energy that Naruto can tap into. For example, Naruto might be able to use the Kyuubi's power to communicate with the spirits of the past. Another way is to show the Kyuubi's power as having different forms. Maybe there's a 'benevolent' form of the Kyuubi's power that Naruto can access for healing or peace - making purposes, as opposed to the more destructive form we usually see.
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.
There should be no such fanfiction as it involves extremely inappropriate and unethical content. Fanfiction should focus on positive, creative and ethical storytelling, not on such offensive and immoral scenarios.
Well, in the 'kyuubi gets bigger' fanfiction, it could be related to a dark magic or an ancient curse. For example, an evil sorcerer might cast a spell on the kyuubi, making it grow uncontrollably. As it gets bigger, it could start to disrupt the balance of nature in the ninja world. And Naruto and his friends would have to find a way to break the spell and stop the kyuubi from causing more chaos.
Yes, there might be such fanfictions in the vast world of Naruto fanfiction. However, this is a rather unusual and non - canonical concept. Some fanfiction platforms may have works exploring such out - of - the - box ideas, but it's not part of the official Naruto storyline.
Well, the 'naruto full power of kyuubi fanfiction' might focus on the battles Naruto can have with his new - found power. He could be taking on stronger opponents that he couldn't face before. For example, he might be able to easily defeat some of the Akatsuki members who were once a great threat. Also, it could be about Naruto exploring the darker side of the Kyuubi's power and how he copes with it.
Obviously Naruto would be a main character. Since he has the kyuubi sealed within him, any change in the kyuubi's state would directly affect him. He would be in the center of the story, trying to deal with the kyuubi getting bigger.
In such a fanfiction, Naruto would likely face extreme danger. The extraction of the Kyuubi would leave him in a very weak state, perhaps near death. His body has been so intertwined with the Kyuubi's chakra for so long that suddenly losing it could cause his systems to shut down. Also, his ninja abilities that were enhanced by the Kyuubi would disappear, and he'd have to relearn how to fight without that power boost.
