One Piece Chapter 48, page 3: GIVE UP ON THAT SEA

Don Krieg continues explaining the origin of Zeff's nickname: "YOUR NICKNAME 'RED-LEG' REFERS TO YOUR LEGS, THAT WOULD BE DYED IN THE BLOOD OF YOUR ENEMIES AFTER A FIGHT." He notes that despite rumors of Zeff dying in a shipwreck, he survived at the cost of one of his legs, concluding, "WITH ONE OF YOUR LEGS GONE, YOU SHOULDN'T BE ABLE TO FIGHT ANYMORE." Sanji listens silently. Zeff raises his hands and replies, "I MAY NOT BE ABLE TO FIGHT ANYMORE BUT I CAN STILL COOK AS LONG AS I HAVE THESE HANDS. BUT JUST WHAT ARE YOU GETTING AT EXACTLY?"
