Monkey D. Dragon

The father of Luffy and the son of Monkey D. Garp. He is the infamous Revolutionary Leader and has been causing trouble around the world.

Appearance
He is often seen in a long green cloak and recently he wears a revolutionary clothes. He has tattoos on his left side of his face and a hairstyle similar to Raditz from Dragon Ball Z.

Personality
His personality is mostly unknown due to the many mysteries surrounding him, save for an apparent love for freedom and belief in fate, which are traits of a D. Unlike other members of his family, or D's for that matter, he looks stern and serious. Like his father Garp, he seems to hold high expectations for Luffy and although has not introduced himself to him, seems to support his sons actions so far. He speaks as though he is a mystic of sorts and according to the World Government, has some very dangerous ideals. He also seems to be incredibly powerful, as the World Government has trouble capturing him, not to mention his tremendous bounty which is unknown at this time (He holds the title of "The World's Most Wanted Man")

Past Story
His history remains mostly a mystery, thus it is unclear why Luffy was left to be brought up by his father Garp instead of himself. At some point he began the Revolutionary movement becoming its leader and his ideals began to slowly spread throughout the world. One by one countries slowly began to support him, though sometimes through war.

The little known history on him is that Six years ago, the Council of the Kings in Mariejois. The meeting was to discuss his revolutionary movement and his ideals that were threating the World Government. Thalassa Lucas showed the picture of him.

Present Story
His first appearance was during the Loguetown Arc where he saved his son Monkey D. Luffy from Captain Smoker. He stopped Smoker from killing his son. At that moment a gust of wind passed through LogueTown blowing Luffy (and several other characters like Buggy the Clown present in LogueTown). It's not known if he used the wind that blows off the marines at this point.

Current Story (spoilers)
While visiting Luffy, Garp let slip that Dragon was Luffy's father in a causal conversation with him. The reaction of those present was of dire shock. It was then revealed to Luffy just who his father was by Robin.

Robin stated that he was the top of the revolutionary army and has spread his ideals to every nation and kingdom, causing many of them to fall into his hands. He manages to stir rebellion around the world and has successfully pushed the world towards civil war. His actions greatly anger the World Government and he is considered the most dangerous man in the world.

Until that moment, no one had known known anything about Dragon, not even his full name.

Finally, after over 7 years(in real time) and 340 chapters since he last appeared, he reappeared again in chapter 440, having to read Luffy's bounty and walks out into the castle's balcony where he remarked that the true nature of the world will be answerd and he will meet Luffy again.

Dragon currently resides on Paladego
