Monkey D. Luffy

Monkey D. Luffy, also known as "Straw Hat Luffy" and commonly as "Straw Hat" is the main protagonist of One Piece. He is the founder and captain of the increasingly infamous and powerful Straw Hat Pirates, as well as one of its top three fighters. His lifelong dream is to become the Pirate King by finding the legendary treasure left behind by the late Pirate King, Gol D. Roger. He believes that being Pirate King means having the most freedom in the world. He is the son of the Revolutionary leader Monkey D. Dragon, the grandson of the Marine hero Monkey D. Garp, the sworn brother of late "Fire Fist" Portgas D. Ace and Revolutionary Chief-of-Staff Sabo, and the foster son of Curly Dadan.

Appearance
Luffy has black shaggy hair, round black eyes, and a slim muscular build. He is renowned for his trademark straw hat (from which he gets his nickname "Straw Hat Luffy"), which was lent to him when he was young by the legendary pirate captain, "Red-Haired" Shanks, who in turn received it from Gol D. Roger. He wears short, blue trousers with cuffs, sandals, and a sleeveless red vest. Luffy also has a scar with two stitches underneath his left eye (which he earned by stabbing a knife under his eye to show Shanks that he was tough and not afraid of pain) and short, messy black hair. He was severely wounded by Akainu in the Battle of Marineford, leaving a large X-shaped scar on his chest. Appearing to be scrawny underneath his shirt, he has a surprisingly well-built physique. He is quite short since he appears dwarfed by most individuals in the series (though it must be noted that characters in One Piece are often very tall by real-life standards).

Luffy wears an open, long-sleeved red cardigan with four buttons with a yellow sash tied around his waist, somewhat reminiscent of Gol D. Roger's outfit. He has grown slightly taller and is shown to be significantly more muscular due to his training. This can be seen in his slightly thicker neck, more pronounced deltoids, and better-defined chest.
