Ace is a 2nd Division Commander of the Whitebeard Pirate. He was fearless, intelligent, and even polite, which made him a prevalent character. Ace was a tall muscular young man with curly black hair. Although they were not blood related, Ace looked remarkably like his foster brother, Luffy. However, Ace was more serious looking than Luffy's lighthearted design, and was also taller and more muscular. Ace is one of Pops/Whitebeard sons and a close friend of Marco and his death friend Thatch.
