Marco

Marco (マルコ, Maruko) is the first division captain of the Whitebeard Pirates.

Appearance
Marco is a blond haired man with a rather sleepy look. While his chest was barren in his initial appearance, in his subsequent appearances he has a cross and crescent moon tattoo on his chest that vaguely resembles a silhouette of Whitebeard's Jolly Roger after Oda changed it.

Personality
Marco appears to be a patient and calm mild-mannered man. He is knowledgeable in the sense that he knew about Shank's powerful Haki.

Powers and abilities
He seems resistant to Shanks' Haki. In addition, he is also one of the top four commanders of the Whitebeard pirates.

Jaya Arc
He first appeared as a background character; when Rockstar asked if anyone knew him, Marco answered "Nope, never heard of him".

Post Enies Lobby Arc
He next appeared when Shanks came to visit. He appeared to be fairly well knowledgeable and experienced with dealing with Shanks since he knew exactly what would happen to the younger crew members in his presence. He also told the members still standing afterwards not to worry about their fallen comrades as they are just unconscious.

Manga and Anime Differences
In the anime when he was first shown, he was replaced with a generic crewmember with black haired man with lighter colored skin and different clothes. This is a common mistake that occurs in transferring a scene from manga to anime and has been witnessed in One Piece before, in particular when characters are first introduced without a formal introduction.
