Here's a bare bones explainer for the One Piece DonSwap!AU that me and @carrioncreations have been kicking around as we watch together, because I want something to point to if I start talking about it in posts:
So... Donquixote Swap AU:
Doflamingo and Rosinante's childhood happens the same as in canon up to the point that Doffy leaves for Marie Geoise (though technically it happens a few years later in the world timeline because we pushed some birth years around for certain age gaps). Rosi is left behind very upset, and Marines soon arrive to sweep the island. However in this AU instead of finding Rosi, Sengoku's squad thoroughly spooks him while searching for "the Celestial Dragons". Insert domino effects leading to Doffy sitting in a cell at a CP9 base while Trebol & co. are accepting they have to make it work with the 8-year-old crybaby. Both assume the other is dead.
11 years later, Rosinante is a notorious up and coming pirate in the North Blue when his dead brother miraculously reappears. He folds him into the crew as Corazon, and starts carefully ignoring that Doflamingo is possibly the most suspicious man he's ever met, won't give a single solid detail about his life before now, loves to disappear for weeks with vague explanations, and is crystal clear on the fact Corazon needs to be a fucking ghost - no government eyes, ever. Because Rosi loves his brother. And if he has to confront him, then he's a little concerned that what comes out is going to irreparably blow up their relationship. Surely this will be fine and no dying Trafalgar Laws will be traumatized.
Highlights of this AU include:
The CP9 Child Soldier Program
This Rosi meme:
Rob Lucci and other dubiously brother-shaped figures
Doffy being king of cognitive dissonance and plans that are great and will work forever so long as nothing ever goes wrong
Crime boss Rosinante being exactly as terrifying as canon Doflamingo with extra arson and immolation for spice
Rosi's grown adult brother wanting to murder his new dying 10-year-old because he's absolutely seething with jealousy and Rosi is the only one who realizes this 🤣
Law's beloved "dead" savior being a gleeful psychopath in pink feathers who has done coke in front of him and was absolutely not hiding a heart of gold, but also spent six months and nearly had a manic breakdown saving him and seemed possibly more panicked about the thought of Law dying than Law was and extra panicked that he cared in the first place, so Rosinante definitely needs to die for killing him
Doflamingo sort of faking his death to put off definitely killing his brother for as long as possible
One man's determination to protect his career slowly sprawling out into a giant cover up at the highest levels of Marine command, entirely because everyone is trying to make someone else be the guy that triggers the lose-lose timebomb of getting caught by / informing the World Government
Law rationalizing to himself: "Doffy says I'm not allowed to make the call on killing his brother, but Doffy is an idiot about Rosinante AND I'm not killing him if I destroy the factory, so..." #PlanStillOn
Dressrosa Family Screaming Match + Collateral Damage, feat. Strawhats / Revolutionaries / an Admiral / etc.
Sabo: "You've killed over 25,000 Revolutionary Army soldiers and associates that we've been able to confirm" / Doffy (fondly): "I did do that"
