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.
Zoro is also sometimes paired with Baby 5 in fanfiction. Zoro's strong and stoic personality is a contrast to Baby 5's more emotional and compliant nature. Fanfiction writers might explore how they could influence each other. Maybe Baby 5 helps Zoro open up more emotionally while Zoro teaches her to be more self - reliant.
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.
Luffy is often paired with Law in interesting ways. Their different personalities and yet similar goals make for great stories. Also, Robin. Her knowledge and Law's skills can create some really cool storylines.
In these fanfictions, a common trope is the 'fish out of water' situation for the reader - character. Since the One Piece world is so wild and different, the reader - character has to adapt, and Law is often there to guide them. Also, the 'enemies to lovers' trope can be seen sometimes. Maybe at first, Law and the reader - character have different goals or misunderstandings, but as the story progresses, they fall in love. And don't forget the 'power couple' trope, where Law and the reader - character are shown as a strong duo in battles and other situations.
Detective Robert Goren is often a popular character. His complex personality and brilliant detective skills make him a great focus for fanfiction. Writers can explore his psychological insights and how he uses them to solve cases. Another popular one is Captain James Deakins. His leadership role and his relationship with the detectives under him can be interesting to write about.
Genos and Rukia could also be a popular pairing. Genos' robotic nature and his loyalty to Saitama could be an interesting contrast to Rukia's cool and collected Soul Reaper self. They might have some unique interactions, like Genos being curious about Rukia's zanpakuto and spiritual powers.
Tashigi is also a favorite. Her determination to collect all the Wazamono - grade swords and her relationship with Zoro add an interesting layer to her character. In fanfiction, she can be developed further, especially in her role as a marine trying to uphold justice in a chaotic world.
Ace was also a very popular character in One Piece gamer fanfiction before his death. His fire - based powers and his connection to Luffy made him a great addition to any story. In fanfictions, he could be a powerful ally or a challenging boss depending on the plot. Trafalgar Law is also getting more popular in these types of fanfictions. His devil fruit ability and his complex personality make for some interesting plot twists in a gamer - style One Piece story.
Luffy and Naruto are often very popular. Luffy because of his carefree and determined nature in One Piece, and Naruto with his never - give - up attitude in Naruto. Fans love to see how these two strong - willed characters interact in fanfiction.
Sanji is another character that is often featured. His chivalry and his own moral code can be put to the test in stories about justice. For example, he might have to make a choice between following the Straw Hats' view of justice or his own personal sense of what is right when dealing with issues like slavery or oppression in different islands in the One Piece world.
