As commander of the 1st division of the Whitebeard Pirates, Marco has authority over the lower-ranking subordinates. Following Whitebeard's death, Marco became the highest authority of the Whitebeard Pirates, and as such the crew was under his command as they retreated from Marineford. He was one of the few men unaffected by the powerful Haki released by the Yonkou Shanks. He is a very experienced veteran, as he was shown as a member of the Whitebeard Pirates from the times of Gol D. Roger.
