Well, in some fanfictions, Naruto gains control of the Kyuubi and then he starts to train others in how to better handle their own inner demons or chakra beasts. It's like he becomes a teacher of sorts. Another common plot is that Naruto uses the Kyuubi's power to travel to different dimensions. He might go to a dimension where the Uchiha clan was never massacred and try to prevent the events that led to so much pain in his own world. And then there are those stories where Naruto, with his new - found Kyuubi - controlled power, challenges the very idea of the ninja hierarchy and tries to create a more equal society among the ninja.
One popular plot is Naruto using the Kyuubi's power to protect Konoha from a new, powerful enemy. For example, he might face off against a group of rogue ninja who have united to take over the Hidden Leaf. Another plot could be Naruto exploring the memories of the Kyuubi, which leads to him learning ancient ninja secrets. This could involve finding lost jutsu or understanding the history of the ninja world better. Also, some fanfictions might have Naruto using the Kyuubi's power to finally bring peace between the ninja villages by showing his overwhelming strength and his will for peace.
