"Orochi, you useless fool. Manage Wano Country properly, or I won't hesitate to replace you."

"Big Mom, behave yourself. My strength is on a whole different level now. I can beat you up without even breaking a sweat."

"What? The Marines won't let me enter the Grand Line? Then I'll go straight and wipe out Marine Headquarters!"
