Monkey D. Dragon

Dragon (ドラゴン, Doragon) makes an appearance to save Luffy from being captured by Smoker. When he saved Luffy from Smoker a mighty gust of green wind swept through Roguetown blowing everyone caught in it away. It is undetermined whether or not he was the cause behind the gust of wind, however the story leads you to believe there is more to him then it seems. Many fans believe he did indeed cause the wind and that he may also be a Devil Fruit user, but neither of these has been proven so far in the story.

Dragon is one of the most mysterious characters in One Piece to this date. He is mentioned once as a revolutionary in the flashback of the Drum Island Arc of six years ago (chapter 142 of the manga). In that flashback, it was told that during the World Government's meeting at Marejois, it was said that in a few years, he would be a threat to the world. He is high on the World Government's wanted list, and looks incredibly powerful. He has not been mentioned or seen since.

In the english dub he is voiced by Dan Green.
