Richard "Dick" Grayson, aka Nightwing, is quickly becoming cemented as one of DC's most important heroes. As Batman's very first Robin, he is certainly one of the most adept and best-trained vigilantes, and he has paid it forward by taking on training responsibilities for an entirely new generation of heroic figures. He initially broke away from his mentor years ago to discover his own voice and place in the world and has done so by leading his team, the Titans, who have recently stood as DC's premier hero team in place of the Justice League.
