Naruto could fit in by using his physical abilities. His superhuman strength, speed, and endurance, which he developed through his ninja training, would make him a formidable opponent in the One Piece world. He could easily take on weaker pirates or even some of the lower - level Marines.
The law is definitely not dead in One Piece. It exists in various forms and degrees, and its enforcement or violation drives many of the story arcs. The struggle against injustice and the search for true justice are ongoing themes related to the law within the manga.
The 'one piece law novel' could potentially be a story that uses the One Piece setting to explore legal concepts. For example, it might look at the legality of the different pirate crews' actions. Some crews might have their own codes that conflict with the world government's laws. It could also be about how the marines enforce the law and what happens when there are loopholes or corruptions in the legal system of the One Piece world.
It depends on how well it has been marketed and the quality of the story it presents. If it offers a unique and engaging take on the One Piece world from a legal perspective, it could gain a decent following among fans who want to see new interpretations. However, compared to the mainstream One Piece products, it may be relatively niche. There are so many spin - offs and related works in the One Piece franchise, and its popularity would likely be a fraction of the main series.
Not at all. Law remains a significant character and has many ongoing plotlines associated with him. His presence continues to shape the events in the One Piece manga.
If Naruto were in the One Piece world, he could form interesting alliances. He might team up with Luffy and the Straw Hats. Naruto's ability to make friends easily would fit right in with the Straw Hat crew's spirit. His Rasengan could be a very powerful attack against some of the strong foes in the One Piece world. Also, his experience with dealing with different types of enemies in his own world would give him an edge in strategizing in the new and strange world of One Piece.
Some fanfiction also pairs Law with Kid. Given that they are both Supernovas and have a somewhat competitive relationship in the main story, in fanfiction, they could end up as reluctant allies or even friends. Their combined strength and different personalities can create interesting storylines.
In a fanfiction where Naruto is a fishman in One Piece, Naruto would face new challenges. For example, dealing with the discrimination that some fishmen face in the One Piece world. But he'd also have new opportunities. He could use his fishman physiology to swim faster and deeper, discover hidden treasures, and maybe even find a way to connect the ninja world with the pirate world. His Nine - Tailed Fox chakra might also have some interesting interactions with the strange powers in One Piece.
In this fanfiction, Naruto and Law's interaction could be complex. At first, their different personalities might cause some friction. Naruto is more open and impulsive, while Law is more reserved and calculating. However, when they see the potential in each other's abilities, they would start to cooperate. Naruto's positive attitude could gradually influence Law to be more open. They might have some friendly competitions, like Naruto showing off his Rasengan and Law demonstrating his Room ability. And in battles, they would learn to coordinate their attacks, with Naruto using his speed and agility and Law using his strategic spatial manipulation.
