In One Piece Aokiji x Robin fanfiction, how could their relationship develop?

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.

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.

Start with small interactions. For example, the OC could accidentally save one of Hancock's pets or help with a small task on the island. This would make Hancock notice the OC in a positive light.

It's quite significant. Aokiji plays an important role in the One Piece manga and his storylines have a major impact on the overall plot.

First, they could start with a mutual interest in knowledge. Robin loves to study history, and if the OC has some special knowledge or a thirst for knowledge as well, that can be a starting point. For example, if the OC discovers a new type of Poneglyph and brings it to Robin's attention.

In a fanfiction, their relationship could develop in a rather unorthodox way. For example, if they both get caught in a devil - fruit - related experiment gone wrong. They are forced to rely on each other to survive and in the process, they realize that they have more in common than they thought. This shared trauma could be the starting point of a deep connection between them.

In a fanfiction, their relationship might develop when Luffy gets injured and Hancock has to take care of him. This would be a new situation for Hancock as she is usually the one being protected. Luffy, in his injured state, would still be his positive self. Hancock would see his vulnerability and also his unwavering spirit. This could lead to a deeper emotional connection between them, with Hancock realizing she wants to be by his side not just because of her love for him, but also because she admires his character.

During time travel, Luffy and Robin might discover new sides of each other. Luffy could see Robin's more vulnerable side when she is faced with historical events that are related to her past and her people. Robin, on the other hand, would be in awe of Luffy's ability to adapt so quickly to any situation in different time periods. This mutual understanding and discovery could lead to a deeper bond between them. They might also share some quiet moments where Robin tells Luffy more about the history she has studied, and Luffy listens intently, strengthening their connection.

In this fanfiction, the plot could develop around the idea of a shared prophecy. There could be an ancient prophecy in both the One Piece and Naruto worlds that foretells the coming of a great being with the combined powers of both universes. Naruto, with his godlike abilities, is seen as a possible candidate. However, there are forces in both worlds that don't want this union to happen. So, Naruto has to fight against these opposing forces while also trying to understand the true meaning of the prophecy. Along the way, he forms deep bonds with the One Piece characters, and together they work towards either fulfilling or preventing the prophecy from coming true.

Perhaps in this fanfiction, Naruto is on a mission in his own world when a strange portal opens and leads him to the One Piece universe right where Robin is. At first, they are both cautious of each other. But as they learn about their respective powers and goals, they decide to join forces. Maybe there's a common enemy that is threatening both the ninja world and the pirate world, and together they strive to defeat it.
