Their relationship in the Zoro x Sanji Christmas fanfic could be presented through a series of challenges and reconciliations. For instance, when they are tasked with getting a Christmas tree for the ship. Zoro wants to just chop down the first tree he sees, but Sanji has very specific requirements. They argue, but then realize that by combining their ideas, they can get the perfect tree. This pattern of arguing and then coming together could be repeated throughout the Christmas celebration, showing the complexity and depth of their relationship.
One great fanfiction could be about their adventures on a new island not shown in the original story. Maybe they encounter a powerful and strange new enemy. Luffy's determination, Zoro's strength, and Sanji's culinary skills all come into play in this new situation.
There might be. However, it's important to note that this kind of fanfiction is more of a creative and often not part of the official storyline. Some fans really enjoy exploring this kind of relationship between Zoro and Sanji in their own fictional interpretations. They might add interesting plot twists and character developments to make the kiss scenario seem more believable within the world they create in the fanfiction.
Often, they involve a lot of emotional build - up. Since Zoro and Sanji have a complex relationship in the original story, in fanfiction, the kiss might be a result of resolving their differences or a sudden realization of deeper feelings.
Well, perhaps in this fanfic, it's a snowy Christmas. Zoro gets lost in a town while looking for a special Christmas drink for the crew. Sanji, worried despite their differences, goes to find him. Along the way, they encounter various Christmas-themed obstacles and enemies. By the time they return to the ship, they have a newfound respect for each other and share a warm moment under the Christmas lights.
Another theme is rivalry. Zoro and Sanji have a friendly rivalry which can be elaborated on in fanfictions. For instance, they might compete in a friendly tournament on the ship to see who is stronger or more useful in a certain situation.
A very popular one is 'Beyond Rivalry'. In this fanfiction, it explores the idea of Zoro and Sanji having to rely on each other completely when they are stranded on an uncharted island. It really shows their growth as characters and how their relationship can be more than just the typical rivalry.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). Just type in 'One Piece Zoro x Sanji' in the search bar, and it will show you a bunch of relevant fanfictions. There are also tags on AO3 that can help you narrow down your search based on what you're interested in, like 'angst' or 'fluff'.
I think it might have been a character introduced to add depth to Sanji's backstory and motivations. But without more context, it's hard to say for sure.
One character that would fit well is Robin. Her knowledge of the world and its secrets could be relevant if there's some mystery involved in the Zoro - Mihawk relationship. Brook, with his unique personality and his own skills as a swordsman, could also be included. He could have some interesting conversations with Zoro and Mihawk about swordsmanship. And Shanks, as a great swordsman himself and a significant figure in the One Piece world, could potentially play a role in the story, perhaps as an old acquaintance of Mihawk.
