One Piece Chapter 13, page 10-12: Chapter 13: TREASURE

Mohji commands, 'RICHIE, BITE HIS HEAD OFF!! KILL!' Richie roars and lunges forward with his jaws wide open. Luffy calmly winds up his arms, twisting them tightly like ropes, and says, 'IT'LL TAKE MORE THAN THAT LION... TO KILL ME!' Mohji watches in horror, screaming, 'WHAT'RE YOU DOING TO YOUR ARMS!? HOW CAN YOU--!?

Luffy unleashes his attack, shouting, 'GUM-GUM... GAVEL!!!!!!' His untwisting arms spin Richie through the air and slam the giant lion headfirst into the ground with a massive crash.

Richie lies completely knocked out, upside down on the street. Mohji panics, screaming, 'RICHIE!!!! WHAT ARE YOU, YOU FREAK!?' Luffy explains, 'A LONG TIME AGO, I ATE THE FRUIT OF THE GUM-GUM TREE!!' Mohji realizes, 'YOU ATE THE DEVIL'S FRUIT, LIKE CAPTAIN BUGGY!?' Terrified, Mohji begs for his life, pleading, 'OKAY, OKAY! I'LL GIVE YOU ALL THE GOLD YOU WANT!!! J-JUST LET ME APOLOGIZE AND GO! ALIVE!' Luffy, his eyes shadowed with anger, replies, 'IT'S TOO LATE FOR APOLOGIES... THEY WON'T BRING THAT DOG'S TREASURE BACK!
