As a direct result of his modifications that he's conducted upon himself as well as years having spent as a ship dismantler, bounty hunter, and street thug in Water 7, Franky is a powerfully built man with a height of at least seven feet, and he is the second tallest member of the Straw Hats. His forearms are relatively enormous while his biceps are comparably small. He has brightly-colored blue hair and blue star tattoos on his forearms. His choice of clothing usually comprises of a speedo, which causes people to call him a pervert, and an open loud Hawaiian shirt with a large golden chain necklace around his neck. During the Straw Hats separation, after blowing up Vegapunk's laboratory, the skin gets burned off Franky's face. He also has a pair of sunglasses which he usually wears when things start to get serious.
