## One Piece Chapter 421, pages 13-16: Gear Third - Chapter: 421 - Pages: 13-16 - Characters: Monkey D. Luffy, Rob Lucci ### Summary Page 13: Luffy is hit by a "STAMP!!!" and drops back, panting. Then he stands again and changes the battle. "HAA... HAA... IF YOU WANT TO HAVE A BATTLE OF FORTITUDES," he says, "LET ME SHOW YOU... MY OTHER TECHNIQUE!!!" Lucci pauses, alert. Luffy grips his thumb between his teeth and speaks the word that gives the chapter its title: "GEAR" and then "THIRD." The quiet before the technique is almost heavier than the fight itself, because Luffy is choosing a power Lucci has not seen and one that clearly costs him something to use. Page 14: Luffy bites into his thumb and forces air into his body. "HAAAAA..." he breathes, then releases the technique: "HONE FUU-SEN!!!" The note of the move becomes visible as his arm swells grotesquely, a "BONE BALLOON" filled by the air moving "FROM BONE TO BONE." Lucci stares and repeats the idea in disbelief: "BONE...!?" Luffy displays the result with wild confidence: "BEHOLD!! THIS LEFT ARM IS..." His body remains small beneath the absurdly massive limb, and the page makes the new technique feel both comical and terrifying. Page 15: The enlarged fist looms in front of Lucci. Luffy names it with pride: "THE ARM OF THE GIANTS!!!" Lucci tries to dismiss it, saying, "IF IT'S JUST ALL LOOKS, DON'T EVEN BOTHER...!!" and prepares "TEKKAI!" Luffy begins the attack again: "GOMU GOMU..." His giant arm draws back with the mass of a weapon far beyond his usual rubber punches. Lucci hardens himself, confident that a defensive technique that stopped Rifle can stop this too, but the scale of the fist suggests the battle has changed completely. Page 16: Luffy's new attack lands with monstrous force: "GIGANT PISTOL!!!" The swollen fist smashes Lucci through the wall and into the outer tower structure, blasting stone apart and throwing debris across the sea-facing side of the building. Lucci's shock is visible in the narrow panel as the impact carries him away. The blow is so large that it looks less like a punch and more like a siege weapon fired from Luffy's body. Gear Third has finally answered Lucci's question about whether Luffy's abilities can match his resolve.
