One possible storyline could be the male reader being a new pirate who arrives on Dressrosa where Viola is. He could initially be mistaken for an enemy but then Viola realizes his true intentions are good. They then team up to help the people of Dressrosa against some new threat that emerges. This would allow for a lot of action and also some romantic tension to develop between them.
Viola is a strong - willed and perceptive character. The male reader's personality could be developed to complement hers. For example, if he is more of a carefree spirit, his positive attitude could influence Viola to be a bit more relaxed at times. And in turn, Viola's seriousness can make the male reader more responsible. They can also have shared values like a love for justice or protecting the innocent, which would strengthen their bond as they face challenges together in the fanfiction.
One common theme is adventure. Since One Piece is all about adventure, these fanfics often have the OC and Viola going on adventures together, exploring new islands and facing challenges. Another theme is romance, of course. Writers like to explore the relationship between Viola and the OC, how they fall in love and deal with the obstacles in their relationship.
One Piece Trafalgar Law x Reader fanfictions are really interesting. They allow readers to immerse themselves in a fictional relationship with Law. A lot of these fanfictions focus on the unique dynamic between the reader's character and Law's complex personality. For example, some might explore how the reader's character influences Law's decisions, or how they navigate the dangerous world of One Piece together. It's a great way for fans to explore different scenarios that the original manga or anime might not cover.
Well, in such fanfictions, the relationship might start off with the reader being in awe of Mihawk's strength. For example, they could meet on an island, and the reader is immediately drawn to his presence. As the story progresses, a bond might form, perhaps through some shared adventures or the reader getting caught up in Mihawk's world of swordsmanship and power.
One popular theme is the power imbalance. Mihawk is extremely powerful, and the reader character is usually much weaker. This creates an interesting dynamic where the reader might look up to Mihawk and strive to become stronger. Another theme could be the exploration of Mihawk's backstory through the eyes of the reader.
One idea could be that the male reader is a new member of the Straw Hat crew. He and Robin gradually develop a bond during their adventures. For example, they could be exploring an ancient island together and the male reader saves Robin from a hidden trap. This shared danger could be the start of their relationship. Another plot could involve the male reader having a special power or knowledge that Robin is interested in, and through their interactions, they fall in love.
One interesting One Piece x Reader fanfiction could be where the reader is a new crew member on the Straw Hat ship. They have to prove their worth and form unique bonds with each member.

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.
