What are the reasons for Luffy being more like Dragon in fanfiction?

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.

One reason could be a devil fruit power gone wrong. Maybe he ate a fruit that was supposed to give him some new ability but had an unexpected side effect of changing his appearance to that of a girl. Another possibility is that he was hit by some strange magic or curse during an adventure on an island. It could also be the result of a prank by some powerful and mischievous character who has the ability to change appearances.

Perhaps Nami is under a curse. The curse makes her see Luffy as a threat, even though he's not. So, she ends up hurting him because she's compelled to by the dark magic of the curse until the crew can find a way to break it.

Maybe in that fanfiction, Nami's character is distorted in a way that Luffy, with his straightforward and honest nature, can't stand. For example, if she is portrayed as overly greedy or mean in a way that goes against the essence of her character in the original work.

He could be bored during a long voyage at sea. With not much else to do, reading fanfiction might be a way to pass the time without his crewmates knowing. Also, he might want to see how others view his adventures and his relationships with his friends in the fan - created stories.

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.

In some fanfictions, character corruption can be a factor. The author might decide to corrupt the pure relationships in the original story. So Ace and Sabo are written as hating Luffy because they are influenced by some external dark force or bad ideology within the fan - created universe.

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 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.
