Marco is a tall, lean, muscular, blond-haired man with a rather sleepy look on his face and some stubble around his chin. He wears an open purple jacket and a light blue sash adorned with an elaborate golden-yellow belt around his waist. He has dark gray knee-long pants and black sandals, and on his left leg he wears what appears to be some sort of straw decoration, in a similar fashion to Arlong.
