Yes, in some fanfictions, Luffy can be more like Dragon. Luffy and Dragon both have a strong sense of justice. Luffy wants to become the Pirate King and free the oppressed islands, which is similar to Dragon's goal of overthrowing the World Government to create a more just world. Also, they both possess great leadership. Luffy leads his crew, and Dragon leads the revolutionary army.
The shared ideology might be another factor. Both Luffy and Dragon seem to oppose the unjust systems in the One Piece world. Luffy wants to bring freedom to the islands he visits, while Dragon aims to topple the World Government which is often seen as corrupt. So in fanfiction, this common ground can be exaggerated to make Luffy more like Dragon.
One common theme is friendship. Just like in the original series where Luffy forms strong bonds with his crewmates, in fanfiction with dragons, Luffy often forms a deep friendship with the dragon. They support each other through various difficulties.
One popular type of 'One Piece' fanfiction involving Luffy and Dragon might be about their eventual reunion. Since Dragon is Luffy's father, many fans like to imagine the moment when they meet again. In some fanfictions, Dragon could be secretly guiding Luffy's journey without him knowing. This adds an interesting layer of mystery to Luffy's adventures as he is unknowingly following a path his father has some influence over.
Well, one possible plot could be that Luffy starts off as a Celestial Dragon but then has a change of heart due to seeing the cruelty and inequality in the world. He might use his privileged position to start making changes from within the Celestial Dragon system.
Perhaps Dragon would also introduce Luffy to some new allies or inform him about the greater political and power struggles in the world of One Piece. This would give Luffy a broader perspective and help him understand the significance of his actions. He might learn about the true nature of the World Government and how to better fight against it, not just for the sake of his crew and friends, but for the freedom of the entire world.
One main theme could be friendship. Luffy is known for his ability to make friends, and in fanfiction with Inami and Dragon, it could explore how new friendships form between them. Another theme might be adventure. They could be on a journey together, facing various challenges.
One popular 'luffy inami dragon fanfiction' might be 'The Adventure of Luffy and Inami with Dragon'. It has an interesting plot where Luffy teams up with Inami and they cross paths with Dragon. The story is full of action and the character interactions are well - written.
She'd probably be more serious. Canon Luffy is carefree and naive in a lot of ways. But Fem Luffy raised by Dragon would likely be more cautious and calculating, having grown up around a revolutionary. She might not be as quick to trust strangers.
A good one could be 'Luffy and the Forbidden Dragon Fruit'. In this fanfiction, Luffy stumbles upon a dragon fruit that was thought to be lost. It gives him some extraordinary powers that are not seen in the original series. The story is filled with exciting battles and new character developments.
