Genbou

Genbou 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. (Source: One Piece Wikia)
