Hero One was Great Britain's foremost hero and the predecessor to the Vanguard's Hero 1. He was a member of the Dawn Patrol. During the Cold War era, as the United States and the Soviet Union governments were stopped by the efforts of the Dawn Patrol and the Freedom Phalanx, who would not tolerate nuclear war, Hero One negotiated a peaceful solution between the two governments, opening up the beginning of the break in close cooperation between governments and hero organizations.
