Gear 4 Luffy Here
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.
