Name: Ace Portgas D.

Nick Name: Fire-Fist

Japanese Name: ポートガス・D・エース

Biography: Portgas D. Ace is Luffy's older brother and the commander of the second division of Whitebeard's pirates. Though it is implied at first that his father is Monkey D. Dragon, his actual father is Gol D. Roger. Rejecting his biological male parent, he only recognizes Whitebeard as his father and took the surname of his mother, because he owes her a great debt. To conceal his existence from the World Government, Portgas D. Rouge carried him for twenty months before giving birth. Afterwards, she died from exhaustion. He has the powers of the Mera Mera no mi (flame flame fruit) which allows him to manipulate, create, and transform into fire. Ace habitually falls asleep in the middle of meals or conversations, a trait also seen with Monkey D. Luffy and Monkey D. Garp. His back bears the mark of Whitebeard–a skull with a white mustache superimposed over a manji. The manji was changed to crossbones in the animated version and in later chapters of the manga.
