Monkey D Dragon

Monkey D. Dragon better known as Dragon the Revolutionary and labelled as The World's Worst Criminal, is a supporting character of One Piece. He is the father of Monkey D. Luffy and the son of the Marine Vice-Admiral Monkey D. Garp. Dragon is a tall middle-aged man with spiky black hair with a widow's peak and a tattoo on the left side of his face, which is colored dark red in the anime and bright red in the manga. He has a bit of stubble on his chin. He is usually dressed in a long green cloak, underneath which he wears the orange garb of a revolutionary. He is most often seen sporting a grin. Only on rare occasions, such as at Roger's execution, has Dragon not been seen smiling.

At Gol D. Roger's execution, 24 years ago, Dragon did not have his tattoo or his stubble on his face.As the leader of the Revolutionary Army, Dragon is dedicated to dismantling the World Government and its corrupt nobility system that allows its World Nobles to oppress lower-class citizens as they please. He considers the corrupt nobility in his homeland of the Goa Kingdom to be the same problem on a smaller scale and was enraged when their self-serving actions caused an innocent noble boy like Sabo to denounce them.[12][13] When he rescued Sabo the next day from being attacked by a World Noble's ship, Dragon was shown with a powerful glare of anger on his face.[14]

Dragon is typically seen with a serious and business-minded disposition and takes care to stay highly informed about the happenings of the world and educate his subordinates about relevant objects and events in current affairs. Dragon is quick to caution his subordinates against celebrating small victories, reminding them of the war they are in and of the World Government's great power.[15] However, he has been shown smiling when reflecting on the changing course of the world, particularly his son Luffy's role in it as a pirate.[16] Dragon is extremely secretive about his personal life and history, as he did not tell anyone in the Revolutionary Army that he was Garp's son or Luffy's father, and once shut down an attempt by Ivankov to ask if he had family out in the world.[17] When the news of his family ties came out following the Summit War of Marineford, Dragon noted that it would help his subordinates to see him as a human for once.[18]

Dragon has shown himself to be an empathetic person, particularly to those who are oppressed by the World Government's system. He checked to see if a young Sabo was all right after seeing him be thrown to the ground, and did not hesitate to take his denouncement of the Goa Kingdom's nobles extremely seriously.[12] He cares greatly for the plights of people who are oppressed by the World Government and their member islands, and seeks them out to invite them to join his fight for freedom.[13] He also cares about the members and associates of his army, as shown when he asked Koala if Nico Robin was doing well.[15] When he was under the impression that Portgas D. Ace was Dragon's son, Emporio Ivankov expected that Dragon would go to Marineford to save Ace,[17] showing that Dragon holds love and care towards his family and possibly his son, Luffy, despite not being involved in his childhood.

Dragon is very unforgiving to those he considers had done wrong, stating he would not forgive Sabo if he really had killed Nefertari Cobra during the Levely no matter the reason, as killing regular royals is not part of the Revolutionary Army's goals.
