The slimmed-down Yonko tears through the upper deck to find the cake she craves. She sees nothing, and Jinbe affirms that there is no cake on the ship, but Big Mom refuses to believe him because that would mean Prospero lied to her and she would have to kill him.

At the end of chapter 889, Jinbe says they’d have to leave the Thousand Sunny if it occurred to it, but he decides to fight back instead.

Despite not finding the cake on the Thousand Sunny, Big Mom attacks the Straw Hats.
Big Mom is furious and thinks Jinbe is saying her son is lying. So she user her Cognac, a giant flaming sword, to attack Jinbe but he blocks her attack with his haki-filled arms.

Jinbe blocks the massive hat-sword with Busoshoku Haki-imbued arms, but even though he stops it for a brief moment, Big Mom quickly overwhelms him with strength and sends him flying into the ocean.

Jinbe sends a significant sea current to douse the ship, which weakens Prometheus. The Fishman then jumps up and uses a powerful Fishman Karate technique, punching Big Mom’s chest with such great force that she falls off the ship.

The Straw Hats then devise a strategy as Brook and Nami weaken Zeus next, and they’re able to escape before Big Mom recover immediately.
