One idea could be that during a dangerous adventure, Zoro and Robin get separated from the crew. They have to rely on each other's skills. Zoro's combat abilities and Robin's knowledge of ancient texts help them navigate through an ancient, forgotten island filled with mysteries and traps.
Perhaps a story where Robin discovers a prophecy that involves Zoro in a crucial way. It could be about an ancient weapon and Zoro is the key to either controlling it or preventing it from falling into the wrong hands. Their relationship then deepens as they work together to fulfill the prophecy's requirements.
Well, a great plot might be that the OC is an artist who can draw the secrets of the Poneglyphs without actually reading them. Robin is fascinated by this ability and they work together to uncover the true history of the world. Also, perhaps the OC has a connection to Robin's past, like knowing someone who was important to her family, which creates an emotional bond between them.
Expect a lot of character exploration. Since Robin has a complex past and Zoro has his own goals and dreams, the fanfiction could delve into how they influence each other. For example, Zoro's pursuit of becoming the world's greatest swordsman might inspire Robin to pursue her own academic or personal goals more vigorously.
Another plot could involve a battle where Law and Zoro have to fight against a common enemy. Maybe a new and powerful pirate group emerges that threatens the safety of their respective crews. They start off not trusting each other fully but as the fight progresses, they learn to work together and combine their unique fighting styles. Law could use his Room to manipulate the battlefield while Zoro unleashes his powerful sword attacks from within the Room, creating a deadly combination.
In Robin x Zoro fanfiction, their relationship can be really interesting. Robin is the intellectual and mysterious one, while Zoro is the strong and determined swordsman. Their interactions might start from a simple comradeship on the Straw Hat crew. Maybe in some fanfictions, Robin's knowledge could help Zoro in his swordsmanship journey, like providing him with historical information about some special swords or fighting techniques from the past.
In the fanfiction, the baby could have some unique abilities inherited from both Zoro and Robin. For example, it could have Zoro's sense of direction in combat and Robin's ability to read ancient texts. This could lead to many interesting adventures as the crew tries to understand and help the baby develop these powers.
One idea could be that during a dangerous adventure, Zoro and Robin get separated from the crew in a mysterious island. There, they have to rely on each other for survival. As they face various challenges together, their bond deepens and a romantic relationship starts to form, filled with their unique personalities interacting. For example, Zoro's tough and straightforward nature combined with Robin's calm and intelligent demeanor.
One idea could be a time - travel plot. Zoro and Robin could be sent back in time to an era that Robin has only read about in history books. Zoro would have to rely on Robin's knowledge to survive, and Robin would depend on Zoro's combat skills. They could also encounter younger versions of their crewmates and have to figure out how not to disrupt the timeline while also trying to find a way back to their own time. This would be a great opportunity to explore their relationship in a new and exciting setting.
One idea could be that the OC has a special power which Zoro becomes possessive over because he realizes its potential in battles. For example, the OC can sense the weak points of enemies, and Zoro wants to keep this ability within the crew for strategic advantages.
Their different personalities make them an interesting pair. Zoro is the tough, straightforward swordsman, while Robin is the intelligent and mysterious archaeologist. In fanfiction, this contrast can lead to some great character - driven stories. For example, Zoro's simple view of right and wrong can clash or complement Robin's more complex understanding of the world's history and secrets.
One interesting plot idea could be that Aokiji, after leaving the Marines, crosses paths with Robin. They start to share their knowledge of the lost history. Aokiji's past experiences in the Marines and his knowledge of certain secrets could complement Robin's search for the true history. Another plot could involve them teaming up against a common enemy who is trying to destroy all evidence of the Void Century. They use their unique abilities, Aokiji's ice powers and Robin's ability to sprout body parts on any surface, to fight off the enemy and protect the ancient artifacts related to the One Piece world's history.
