Portgas D. Ace

Portgas D. Ace (ポートガス・D・エース, Pōtogasu D. Ēsu), also known as Gol D. Ace, is commander of the 2nd division of the Whitebeard Pirates and the adopted elder brother of Monkey D. Luffy. He was later revealed to be the son of the Pirate King Gol D. Roger and took his mother's surname Portgas after the death of his father. When one of his subordinates, Marshall D. Teach, killed another crew member, Ace swore to hunt him down only to lose track of him and was eventually handed to the World Government after losing to Teach in a duel. Ace was sentenced to death which resulted in the Marineford War, an event that took the lives of both Ace and Whitebeard. Players can unlock him in the third game's Dream Log Mode.

Personality
Ace is an intelligent but sometimes impatient young man who always treasures his friends. He treats Whitebeard as his father and the Whitebeard Pirates as his family. He also cares about Luffy to a great extent. He is also somewhat narcoleptic, a trait that became one of the many running gags of the series.
