Marco

Marco (マルコ, Maruko) is the first division captain of the Whitebeard Pirates. He first appeared as a background character in chapter 234; when Rockstar asked if anyone knew him, Marco answered "Nope, never heard of him"

It was not until 200 chapters later in chapter 434 that he was givin a name and role in the series. He appears to be a patient and calm mild-mannered man, and he look very sleepy and displayed no emotion except when he told Shanks to shut up in a loud voice.

He is skinny, with a cross and crescent moon tattoo on his chest. His eyebrows are dome-shaped but at the end are curved down sharply before going a bit up, making him look creepy.
