Ishigo is a pale man with short black hair and a black mustache. He wears a white shirt with purple overalls.
He is somewhat sneaky, as he tried to take the Straw Hats' gold for less money than it was worth.
Water 7 ArcEdit
When Luffy, Nami, and Usopp brought him their gold to exchange for cash, he appraised it to be worth 100,000,000. Nami then got angry and told him to stop lying, saying that the gold was really worth 300,000,000. Ishigo realized that he had been caught and became frightened of Nami. He then gave them the full cash value of their gold.
