One common theme is the power dynamic. Since the dragon girl usually has unique and often powerful abilities, it creates an interesting power balance with Naruto. Another theme is discovery. Naruto discovers the dragon girl's world and she discovers his.
One popular 'naruto x dragon girl fanfiction' might be 'The Dragon Girl's Bond with Naruto'. It often explores how the dragon girl's unique powers and her relationship with Naruto develop. Another could be 'Naruto and the Dragon Girl's Adventure' which takes them on an exciting journey through different lands in the Naruto universe.
Yes, there are some. You can start by looking on fanfiction websites like Archive of Our Own. Some fanfics in this genre might explore unique storylines where Naruto is paired with a bunny - girl character, perhaps in an alternate universe setting.
Naruto would probably be very curious about the Dragon Queen. He'd be excited to see her dragons and might try to befriend them. The Dragon Queen, on the other hand, would be cautious at first. But Naruto's friendly nature and his display of powerful ninja skills could earn her respect. They'd likely have conversations about their different worlds, with Naruto talking about his friends in the Hidden Leaf and the Dragon Queen about her claim to the Iron Throne.
One that I've heard is quite good is 'Naruto and the Dragon Princess'. It has an interesting plot where Naruto meets a dragon girl from a different realm and they develop a relationship through various adventures. The story does a great job of blending the Naruto universe with the concept of a dragon girl.
Power and its use is another theme. Naruto has his own set of powers like chakra manipulation, and in The Dragon Prince world, there's magic. Fanfictions may show how these powers can be combined or used against each other, and how the characters deal with the responsibility of having such powers.
One common theme could be an unlikely pairing. Naruto's world is full of ninjas and battles, and pairing him with a bunny - girl - like character creates an interesting contrast. Another theme might be about acceptance, where Naruto and the bunny - girl character learn to accept each other's differences.
In this fanfiction, the role of Mikoto is also very interesting. She has the power to change Sasuke's gender, which implies a certain level of control or influence. It could be that she has some ulterior motives for doing this. Maybe she wants to see how Naruto and Sasuke's relationship will develop in this new situation, or perhaps it's part of a larger plan within the fanfiction's universe.
There's also 'Fox Girl's Affection for Naruto'. In this one, the fox girl is initially a bit of an enigma, but as the story unfolds, her relationship with Naruto deepens in a really sweet way. It's full of cute moments and some exciting battles as well.
The appeal often lies in the unique combination. Naruto has his own charm and the addition of a fox girl, which ties into the whole fox - related lore in the Naruto world, creates an interesting dynamic. It can bring in new storylines about different clans and powers.
