When Does Luffy Use Gear 3 〈Working × GUIDE〉

Furthermore, Luffy reserves Gear Third for the final, climatic phase of a major boss battle. The technique has a crippling drawback: after the air escapes, Luffy temporarily shrinks into a child-sized, chibi form, drastically reducing his strength and mobility. Consequently, using it prematurely would be suicidal. In his fight against Gecko Moria, Luffy waits until he has absorbed 100 shadows and is in his "Nightmare" form before using Gigant attacks. Against Rob Lucci, he only inflates his fist after Lucci has been worn down by Gear Second. In the Sabaody Archipelago arc, he attempts a Gigant Pistol against a Pacifista, but the attack is insufficient, proving that he uses the move only when he believes it is a guaranteed finisher. This tactical hesitation shows that Luffy understands Gear Third as a "king's move"—if it fails, he is left completely vulnerable.

During the war to save Ace, Luffy uses Gear 3 briefly to break through the wall defenses created by the Marines. He uses "Gomu Gomu no Giant Stamp" to smash through the siege walls, showing that he can now use the form more fluidly, though he still shrinks afterward (at this point in the story).

After training with Silvers Rayleigh, Luffy mastered Gear 3.

Throughout the One Piece saga, Monkey D. Luffy’s ingenuity as a fighter is defined by his ability to transform his own body into a weapon. Following the destabilizing speed of Gear Second, Luffy develops Gear Third: a technique that inflates his bones by blowing air into them, transforming his limb into a massive, wrecking-ball force. Luffy does not use Gear Third as a casual attack; he deploys it as a strategic last resort, reserved specifically for overcoming immense physical barriers, destroying nearly indestructible objects, and delivering a decisive, fight-ending blow against opponents whose durability surpasses conventional combat. In his fight against Gecko Moria, Luffy waits
