Monkey D. Dragon

Monkey D. Dragon is the father of Monkey D. Luffy and the son of Monkey D. Garp. He is the infamous Revolutionary leader who has been attempting to overthrow the World Government. He is the World Government's greatest enemy, and is the most dangerous and most wanted man in the world. Dragon is usually seen dressed in a long green cloak (colored black in the manga), underneath which he wears the garb of a revolutionary, colored white in the anime, and orange in the manga. He has spiky black hair with a widow's peak hairstyle, and what resemble tribal tattoos on the left side of his face (which he received sometime after Gol D. Roger's death), they are colored dark red in the anime, and bright red in the manga. Also, he appears to have no eyebrows, however, he does have a bit of stubble on his chin in the form of a goatee. He is most often seen sporting a sinister grin on his face, further aiding his already intimidating visage. Only on rare occasions, such as at Roger's execution, has Dragon not been seen smiling.

Twenty two years before the start of the series, at Roger's execution, his appearance was the same as it is now except he did not have his tribal tattoos or his stubble. He is the leader of the Revolutionaries and has full command of the organization. There have been some hints that Dragon may be one of the most powerful characters in the entire One Piece series, since the World Government has dubbed him as the "World's Most Wanted Man". After Luffy tells Emporio Ivankov that Ace is his brother, the okama queen greatly fears the possibility of the World Government warring against Dragon along with Whitebeard. Dragon is already a powerful threat in his own right, as well as having powerful subordinates such as Sabo, Emporio Ivankov, Bartholomew Kuma, and Inazuma who are in comparison, lower in rank. This only speaks volumes of Dragon's true power. When Sengoku told everyone of his relationship with Luffy, most people were stunned, including Gekko Moriah of the Shichibukai and members of the Whitebeard Pirates. This reputation alone was enough for Luffy to be marked as a dangerous potential to the future, and for Demaro Black to take advantage of via impersonation. Ivankov has been seen commenting on how Luffy's will to live and his phenomenal strength only helps to prove the idea that he is indeed Dragon's son, implying that Dragon has similar strength and will.
