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.
For the OC, give them a distinct personality trait. For example, if they are overly curious, it can lead to interesting interactions with Robin's love for knowledge and Nami's practicality. Show their growth over time, like learning from Robin's wisdom and Nami's street - smart ways.
A different approach could be a fanfic where Nico Robin discovers she's pregnant first, and Nami later. Robin could be more calm and collected about it initially, while Nami is a bit more panicked. But as time goes on, they both grow into their new roles as future mothers. The story could also explore how their pregnancies change their relationships with the other crew members and their own personal goals.
There's a fanfic called 'Fateful Encounters'. In this story, the OC meets Nami and Robin in a rather unexpected situation in a bustling port town. The author does a wonderful job of developing the relationships gradually. As the story progresses, they embark on a journey to find a hidden treasure, and throughout the adventure, the bond between the OC, Nami, and Robin deepens.
Maybe the OC is from a long - lost island with unique knowledge. Robin is interested in the historical aspects of this knowledge and Nami sees the potential for great treasures. The OC then has to deal with the different personalities of Robin and Nami. Robin is calm and intellectual, while Nami can be feisty. Their interactions lead to a series of adventures and a deepening of their relationships.
A luffy x nami x robin fanfic often explores the complex relationships among these three characters from 'One Piece'. It could show their different interactions, like Luffy's carefree nature affecting Nami and Robin in unique ways. Maybe it delves into how they support each other during their adventures on the Grand Line. For example, Luffy's determination might inspire Nami and Robin to be braver in the face of danger.
Often, these fanfics highlight their strong female friendship. They show how Nami and Robin, being two intelligent and capable women in the Straw Hat crew, support and complement each other.
Yes, there are likely many fanfics that focus on their adventures without involving pregnancy. For example, there could be ones about them exploring new islands, facing powerful enemies together, or uncovering ancient secrets. These types of fanfics would center more on the action and camaraderie aspects of their relationships.
To write a great fanfic, start with a strong plot. Maybe there's a prophecy about their children being very important in the One Piece world. This would add an interesting layer to the pregnancy story. Develop the relationships between the characters well. Show how the other Straw Hats interact with Robin and Nami during this time. And don't forget about the details. Describe how they might decorate a nursery on the ship or what kind of baby clothes they'd get.
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.
