One common theme is friendship exploration. Since Nami and Robin are both important female characters in One Piece, their relationship can be explored in deeper ways, like how they support each other through tough times. Another theme could be adventure - related, where they go on a side - adventure together and face challenges that strengthen their bond.
Some fanfictions might explore their pasts and how that affects their present relationship. Nami's history with Arlong and Robin's with the World Government are rich areas to draw from. By delving into these past traumas, the fanfiction can show how they heal and grow together, which is a very interesting theme in many of these works.
One common theme is the exploration of their relationship in different settings. For example, in some fanfictions, they might be in a situation where they have to rely on each other more than usual, which deepens their bond.

Since they are all part of the Straw Hat crew in One Piece, fanfictions often involve them going on new adventures together, facing new enemies or exploring uncharted islands.

Well, I can't really speak for all of them as I don't actively seek such fanfiction. But generally, if it's a crossover like this, there might be themes of two characters from different worlds coming together. Maybe there's some initial confusion or curiosity about each other's powers and worlds. But again, the 'lemon' aspect might add themes related to romantic or more adult - like interactions which are not appropriate for a general discussion.
One common theme is friendship. Nami and Vivi have a strong bond in the One Piece series, and fanfictions often explore how this friendship endures different challenges. For example, they might face a powerful enemy together and have to rely on their trust in each other to get through it.
Romance is also a big part. Usually, it focuses on Nami's relationship with a specific character from One Piece, and the 'lemon' aspect adds a more sensual or passionate side to that relationship. It could be about her relationship with Luffy, Zoro or other crew members in a more romantic and adult - themed way.
One common theme is friendship development. Since they are both part of the Straw Hat crew, many fanfics explore how their friendship deepens over time. Another theme could be adventure - based, where they go on a special mission together and rely on each other's skills.
One common theme could be the power dynamic between Slade and Robin. Since Slade is often portrayed as more powerful and experienced, it creates an interesting dynamic in the fanfiction. Another theme might be the forbidden nature of their relationship, considering their different sides in the story's context.
Adventure is a very common theme. Since Nami and Robin are part of the Straw Hat crew in One Piece, many fanfictions involve the OC joining them on their adventures in the Grand Line. For example, they might go on a quest for a lost treasure or to discover a new island.
Common themes might include power dynamics. Given Slade's more experienced and often menacing nature compared to Robin, there's often a play on who has the upper hand in the relationship. Another could be redemption, where Slade might be on a path to redemption through his relationship with Robin.
One common theme could be the exploration of their relationship in a more romantic and sometimes sexual way. Since it's 'lemon' fanfiction.
