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.
Perhaps the kyuubi gets more power through a pact with another powerful being. It could be a spirit from a different realm. In this fanfiction, they make an agreement where the kyuubi gains new powers in exchange for some future service. This would lead to the kyuubi having to face moral dilemmas as it tries to figure out how to use its new - found powers while fulfilling its side of the pact.
It could also be that the kyuubi gets more power as a result of its own self - discovery. It delves deep into its own nature and finds latent powers that it never knew it had. For example, it might find out that it has the ability to manipulate time on a small scale. This new power would change the way it interacts with the world around it and the other characters in the fanfiction.
