I'm not entirely sure as I haven't read that specific fanfiction. But it might be about Naruto having some sort of connection to a dragon king. Maybe he gains dragon - like powers or has to deal with a dragon king in a new adventure.
The unique element is the Dragon King power. It often gives the characters abilities not found in the original Naruto series, like the power to control water in a more dragon - like way or the ability to breathe fire.
You can try looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a large collection of Naruto - related fanfictions.
One great Naruto Dragon King fanfiction is 'The Dragon King's Ascent in Naruto'. It features an interesting plot where the main character gains the powers of the Dragon King and uses them to change the Naruto world in unique ways.
They might intersect through character crossovers. Imagine a scenario where a character from Naruto has the ability to use Fairy Tail - style magic. And when it comes to the Dragon King, perhaps it's a powerful entity that affects both the Naruto and Fairy Tail universes. For instance, the Dragon King could be a threat that forces characters from both Naruto and Fairy Tail to team up. This could lead to really interesting interactions between the ninjas and the mages.
One idea could be that the Dragon King is a long - lost entity that once had a connection to both the Naruto and Fairy Tail worlds. In the fanfic, Naruto and his friends are on a quest to find out more about this entity and end up in the Fairy Tail world. There, they meet the Fairy Tail guild members and together they try to uncover the secrets of the Dragon King.
One possible fanfiction could be where Naruto discovers a dragon during one of his solo adventures. Maybe the dragon is injured and Naruto uses his kind heart and ninja skills to heal it. As he holds the dragon, he forms a special bond with it, and the dragon becomes his powerful ally in future battles against stronger foes.
Naruto would first be cautious, but then his friendly nature would take over. He'd try to find common ground with the dragon. Since he has a connection with all living things, he'd attempt to communicate with it on a deeper level. He might share his dreams and stories with the dragon, hoping to gain its trust.
It could be a majestic golden - scaled dragon that has been living in seclusion for centuries. Maybe it's a dragon that has the ability to control time, and Naruto's encounter with it is fated. The dragon might be female and is attracted to Naruto's strong will and determination.
