A great Corazon Doflamingo fanfic could be one that delves into his relationship with his family members other than Law. Maybe it shows how his relationship with his brother was like before things went sour. It could also explore his connection with his father and how that influenced his view of the world. Fanfics like these can add more layers to his already complex character.
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.
Some dedicated One Piece fan forums might also be a good place to look for Corazon Doflamingo fanfics. For example, Reddit has One Piece - related subreddits where fans sometimes share their own fanfics or recommend ones they've read. Additionally, Tumblr can have some really creative fanfics, although they might be a bit harder to search for compared to the other platforms.
There's also 'Broken Ties'. In this fanfiction, it focuses on the emotional turmoil that their relationship causes. It shows how their different ideologies clash and yet there are still underlying feelings that neither can fully ignore. It's a really interesting take on their relationship.
I really like 'Doflamingo's Unseen Side'. It presents a different perspective on Doflamingo. It has a lot of action scenes and also explores his relationships with other characters in the One Piece universe in a unique way.
For Doflamingo, you can focus on his flamboyant and unpredictable nature. Show his sadistic side in how he deals with enemies, but also explore his more vulnerable moments, like when his plans are thwarted. For Crocodile, emphasize his cool and calculating demeanor. Let his past failures fuel his actions in the fanfiction, like his determination to regain his lost status. Maybe show how Doflamingo's chaos sometimes clashes with Crocodile's order.
One character that would make for an interesting pairing with Doflamingo in a crossover fanfiction is Zoro. Zoro's strong sense of justice and his skills as a swordsman would clash with Doflamingo's devious ways. They could have epic sword battles, and Zoro might be the one to cut through Doflamingo's strings, both literally and metaphorically. Also, Nami could be paired with Doflamingo. Nami's intelligence and ability to manipulate situations for her own gain, although in a more positive way compared to Doflamingo, could lead to some really interesting interactions. She could try to outwit him in a game of wits.
First, they should start with some kind of conflict or misunderstanding. For example, if the OC is a Marine - in - training and Corazon is undercover as a pirate, they'd be on opposite sides at first. Then, through a series of events where they see each other's true natures, like the OC seeing Corazon protect innocent people or Corazon seeing the OC's sense of justice that goes beyond the typical Marine view, they can start to build trust. This could lead to them working together on small tasks at first, and as they learn more about each other, their relationship can grow deeper.
I'm not entirely sure about the main characters in 'Corazon Indomable'. But typically, in a telenovela, there would be a female lead who is strong - willed and a male lead who is charming.
