Bartolomeo can be rather vulgar and laid-back at times. He is also very provocative, as Bartolomeo not only taunts people with his shenanigans but also mocks his opponents, usually in a nonchalant manner. Even when attempting to stay cool, however, Bartolomeo can become angered when provoked in return. Despite the cruelty he shows to others, he has immense respect for the Straw Hat Pirates. He's a bit of a fanboy.
