Monkey D. Dragon, also known as the "Rebellious Dragon", is a 55-year-old man and the infamous Supreme Commander of the Revolutionary Army and one of its founding members, as well as formerly the captain of the Freedom Fighters. He used to be part of the Marines but became disillusioned with the organization's outlook on justice; this, along with the fallout from the Ohara Incident, sparked Dragon's desire to attempt to overthrow the World Government.
