Genbou (ゲンボウ, Genbō) is one of the Shandian warriors that fought to take back Upper Yard from Eneru. He is fat and bald, and wears a chef's hat. He uses a bazooka which fires rare (in Skypiea) iron cannonballs as his weapon. He loses to Yama in the Survival Game, but later recovers as the war ends. He is voiced by Brad Jackson, and by Adrian Cook for his younger self, in the Funimation English dub.
