In this fanfiction, perhaps Luffy uses the Copy - Copy Fruit to copy the ability to fly from a certain character. Then he can explore new areas that were previously inaccessible. He might also use this flying ability in combination with his rubber powers to perform amazing acrobatic maneuvers during battles, making him even more unpredictable and difficult to defeat.
Definitely Luffy is the central character. In addition to his crew, there could be new characters created specifically for this fanfiction. Maybe there's a powerful villain who has a unique power that Luffy tries to copy. This villain would be a major character as Luffy's actions and development are centered around trying to overcome this foe and make use of the copied powers against him. There could also be a mentor - like figure who helps Luffy understand the full potential of the Copy - Copy Fruit.
One interesting luffy dragon fruit fanfiction could be about Luffy discovering a new type of dragon fruit that gives him the power to control time. He then uses this power to go back and prevent some of the tragedies that happened to his crew. This would add a whole new layer of depth to his character and the story.
One interesting idea could be that Luffy has to rely solely on his Haki and physical training, making him even more of a badass in combat. He might develop unique fighting styles that we haven't seen in the original story where he had devil fruit powers.
A long copy paste story might be a travelogue. You could start with a person leaving their home town and traveling to a far - off destination. They copy paste their experiences at each stop. Like when they reach Paris, they describe the Eiffel Tower, the cafes, and the art galleries. Then as they move on to Venice, they copy paste about the canals, the gondolas, and the beautiful architecture. It's like stitching together different experiences into one long story.
One consequence could be that the character becomes a target. Since having the ability to copy Devil Fruit powers is extremely powerful, many villains would want to either control or eliminate the character. This would put the character in constant danger.
The idea of characters using copied bloodlines to break the traditional power hierarchies in the Naruto universe is also quite engaging. They could use these abilities to challenge the established clans and their dominance, opening up a whole new set of power dynamics and political intrigue within the fanfiction.
In some naruto bloodline copy fanfiction, there might be a plot where the ability to copy bloodlines is not limited to just the main characters. This could cause chaos in the ninja world as more and more people start using powers they weren't originally supposed to have. It would be interesting to see how the different ninja villages deal with this new threat or opportunity.
One interesting idea could be that Luffy's dragon devil fruit gives him the ability to control different types of weather related to dragons, like summoning thunderstorms or creating strong winds. Another could be that he gains the power to transform into a dragon - like form with enhanced strength and speed.
One story could be about a school project. For example, a group of 8th graders had to do a presentation on a historical event. They copied and pasted some information from the internet at first, but then they realized they needed to put it in their own words and add their own research. So they went to the library, found some old books, and combined that knowledge with what they had initially copied. In the end, they created a really great presentation.
Another possibility is that the character has some sort of technological device. In a more sci - fi inspired fanfiction, a super - advanced gadget could be created that can scan and reproduce the energy signatures of Devil Fruit powers. This device might have been created by a brilliant scientist who was studying the Devil Fruits. The character then gets their hands on this device and uses it to copy the powers. However, using this device might come with its own set of risks, like overloading the body with too much power or attracting unwanted attention from powerful villains.
