There's 'Smoker's Dilemma'. In this fanfic, Smoker is constantly conflicted between his duty as a marine and his growing understanding of Luffy's ideals. It's really interesting to see how their relationship develops over the course of the story.
Another theme is friendship development. Since they start as adversaries, many fanfictions show how they slowly become friends or at least respect each other more. For example, they might find common ground in protecting the innocent or in taking on a powerful villain.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. There, you might find various interpretations of the relationship between Ace and Smoker. Some stories could focus on their unlikely encounters in the One Piece universe, while others might explore a more in - depth emotional connection between the two characters.
Archive of Our Own is a great place to start. It has a large collection of fanfiction, and you can easily search for ace x smoker fanfiction using the search bar. Just type in 'ace x smoker' and a list of relevant stories will come up.
First, understand the characters well. Luffy is carefree and driven by his dreams, while Smoker is strict and upholds justice. For the 'lemon' part, if you want to add a romantic or more adult - themed element, do it in a way that is in - character. Maybe start with building a unique plot where they are forced to interact in a new way, like being stranded on an island together.
A great Smoker x Luffy fanfic stands out when it explores their ideological differences. Luffy is all about freedom and adventure, while Smoker is a marine with a sense of justice. When a fanfic delves into how they can coexist or even learn from each other, it becomes really engaging.
Well, 'Luffy and Ace: Unbreakable Ties' is a fanfiction that I really like. It focuses on their childhood memories and how those shaped their relationship as they grew up. There's also 'Ace and Luffy's Great Escape' which is full of action. It shows their cleverness in getting out of difficult situations. 'Luffy and Ace: The True Friendship' is a must - read too. It simply and effectively shows the depth of their friendship.
In 'One Piece' they are on opposite sides, so in fanfiction, seeing them interact in different scenarios is fascinating. For example, they could be forced to team up against a common enemy. Their different abilities, like Smoker's smoke - based powers and Ace's fire powers, can also lead to some really cool fight scenes and power combinations in the fanfictions.
One example could be a story where Luffy and Smoker are forced to team up during a strange pirate - marine alliance situation. In this fanfiction, their initial animosity slowly turns into mutual respect as they face a powerful common enemy. The 'lemon' aspect might be subtly added with some underlying romantic tension that builds between them during their adventure.
A possible plot is that Fem Luffy accidentally gets involved in one of Smoker's investigations in a new island. She initially seems like a hindrance to him, but as the story progresses, they find out that there is a much larger conspiracy at play that involves both the Marines and some powerful pirate groups. They have to work together to expose the truth, and during this time, a strange friendship starts to form between them.
