Gear Fourth (Gear 4) is a transformative technique developed by Monkey D. Luffy following his two-year training under the legendary Silvers Rayleigh on Rusukaina Island. It represents a paradigm shift from his previous Gears (2nd and 3rd), combining immense physical power, advanced Haki application, and creative bodily inflation.

The Three Signature Forms Luffy adapts Gear 4 into specialized forms depending on the opponent: Form Focus Key Features Boundman Balance The standard form used against Doflamingo. It prioritizes overall power and mobility, though its constant bouncing makes standard standing difficult. Tankman Defense A massive, defensive version used to "tank" damage. The "Stuffed Version" famously defeated Charlotte Cracker by using his own biscuit-enhanced momentum against him. Snakeman Speed A leaner form designed for rapid-fire strikes. It uses the "Python" technique to change the direction of punches mid-flight, accelerating with every turn to bypass an enemy's Guard.
