Kizaru (real name Borsalino) is a Marine Admiral. He first appears at Sabaody Archipelago when Luffy knocks out a World Noble, attracting the attention of the marines and causing them to dispatch an admiral to the aid of the World Nobles. He leads the marines in the battle against the Straw Hat pirates, along with his comrade Sentomaru. He fights against the old pirate Silvers Rayleigh, while the former first mate of Gol D. Roger holds Kizaru off to buy the Straw Hat Pirates time for escape. After Bartholomew Kuma sends the pirates flying away, Kizaru demands to know why he let them escape, to which no answer was given.
