How Luffy Invented Gear 4: the 2-Year Ruskaina Training Secrets
By David Miller
During the Whole Cake Island arc, Boundman encountered its direct counter in Charlotte Katakuri. Katakuri's ability to peer several seconds into the future using advanced Observation Haki rendered Boundman’s heavy, predictable arcs ineffective. Katakuri simply molded his Mochi-Mochi body out of harm's way before Luffy's fists made contact.
Luffy adapted by deploying Snakeman in Chapter 895 and Episode 870. In this variation, the muscle inflation focuses entirely along the limbs rather than bloating the torso. Instead of relying on brute destruction, Snakeman deploys the Python mechanic: punches accelerate exponentially the longer they stretch and bounce through air corridors.
By combining this accelerating trajectory with Luffy's own budding future-sight Observation Haki, the form bypassed Katakuri’s evasion windows. The attacks struck from blind spots Katakuri had already ruled out, confirming Gear 4 as a modular combat system capable of evolving to counter distinct tactical challenges.
