The fanfic is called Sweet and Sour by Eexis. It's a One Piece story that includes the AOT cast, but most of them aren't in major roles. Instead the major characters are Mikasa and Eren in the roles of Big Mom and Kaido. The story is in its very early stages, with the writer's plan being to adapt the Whole Cake Island and Wano arcs. What has me interested in the story so far(heck I comment many times lmao), is its concept of Mikasa and Eren having "higher" status than Linlin and Kaido because of their mindsets. They're still human and the same size though. Compared to Linlin and Kaido they have higher bounties, more territory, more intelligence as captains and rulers, and it seems like their subordinates will be stronger
It's even where I got inspiration for the goals of my rewritten BM: https://worstgen.alwaysdata.net/forum/threads/how-would-you-rewrite-big-mom-here-are-my-ideas.28391/
Here's the story if you want to check it out: https://archiveofourown.org/series/2781256. There are only four chapters out, so for anyone who's not interested in reading I'll summarize its renditions of the Emperors here. Keep in mind the author is planning to go back and edit things.
"Big Mom" Mikasa Ackerman: She is the captain of the Big Mom Pirates and The Strongest Woman in the World. Mikasa's goal is to create an empire separate from the World Government; to show the world they are not absolute. Her family, the Ackerman Family, consists of 51 children who all admire their mother, marry based on compatibility, and at least three endured rigorous training as kids. Through 49 years of political alliances and marriages, conquests, and constantly battling pirates and Marines including Roger/Whitebeard, she has forged a massive empire named Totto Land. Totto Land is a monarchic empire comprised of 200+ islands across the New World, Fishman Island, North and West Blue, and hidden East Blue islands.
Possessing a current bounty higher than Whitebeard's, a bounty of 5,139,019,000, the World Government is trying to topple Mikasa Ackerman's empire.
"The Destroyer" Eren Yeager: He is the captain of the Beasts Pirates and The Strongest Creature in the World. Eren possesses knowledge of Joyboy's history, and his goal is to destroy everything about the World Government. Starting off his career as a captain by raiding WG research facilities, he then proceeded to take over Wano silently via scouts and the conquest of all surrounding islands. The Beasts Pirates' current activities are amassing Artificial Devil Fruits, Artificial Giants, and weaponry to prepare for the execution of the Destroyer's plan. In addition, they trade weapons to destabilize the world. Unlike canon, Queen the Plague is a truly monstrous opponent. The fanfic's short summary of the Dressrosa Arc's events wrote him to be strong enough to defeat Admiral Akainu, live to tell the tale although injured, and then fight Jesus Burgess.
Possessing a current bounty higher than even Gol D. Roger's, a bounty of 5,913,800,000, the World Government is trying to topple Eren Yeager's empire as well.
