I'm not really into this kind of fanfiction much. But generally, in such fanfictions, the relationship between Doflamingo and Law might be explored in a very different way from the original story. Maybe it focuses on their power dynamics and how they interact with each other in a more personal or emotional level.
Power dynamics is a very common theme. Doflamingo is a powerful character, so when paired with an OC, their relationship often involves struggles for control or mutual respect based on power. For example, in many stories, the OC has to find a way to hold their own against Doflamingo's authority.
Power dynamics is a very common theme. Given that both Law and Doflamingo are powerful characters in their own right, fanfictions often explore how they interact in terms of power. For example, who has the upper hand in different situations.
Power is a common theme. Both Doflamingo and Crocodile are powerful characters in their own right, and fanfics often explore how their powers interact when they are together. For example, in some fanfics, they might compete to show who is more powerful.
One common theme could be the clash of their personalities. Luffyko's more carefree and adventurous nature against Doflamingo's more calculating and menacing side. This contrast can create interesting dynamics in the fanfic.
Power dynamics is a common theme. Doflamingo is a very powerful and manipulative character, and Law has his own set of skills and goals. Their interactions often involve a struggle for power or influence over situations or other characters.
The contrast between their characters. Doflamingo is this power - hungry and somewhat cruel character, while Corazon is more empathetic. Their relationship is a mix of loyalty and conflict, which makes for great storytelling in fanfiction.
Finally, use vivid descriptions and good dialogue. Describe their appearances, the settings they are in, and their emotions. Good dialogue can bring the characters to life and show their relationship development. For example, Viola might say something like 'I know you have done bad things, but I see a glimmer of good in you' to Doflamingo, which can start a whole new dynamic between them.
One great doflamingo x crocodile fanfic is 'The Unlikely Alliance'. It delves into a world where Doflamingo and Crocodile are forced to work together on a mission. Their personalities clash at first, but as the story progresses, they start to understand each other better.
One common theme could be power struggle. Doflamingo is a very powerful character and Law also has his own strength. In fanfiction, this power play between them can be a central theme. Another could be the idea of redemption or corruption. Depending on how the story is written, one character might influence the other in terms of moral standing.
