Ricardo Diaz, Jr., better known as Richard Dragon, is a villain in DC Comics, and an enemy of the Green Arrow. He is the leader of the Longbow Hunters and a crime lord based in Seattle. He was the main antagonist of the Jeff Lemire/Andrea Sorrentino run on the Green Arrow comic series.
Ricardo Diaz, Jr. was trained by the League of Assassins and vowed to take revenge on the Green Arrow after watching him and John Diggle humiliating his father. Diaz eventually murdered his mentor, the first Richard Dragon, and took his name for himself.
Returning to Seattle, Richard Dragon started to take down several crime lords in order to take over their turfs. When Count Vertigo started his attack on Seattle, Dragon tracked down Shado and fought and easily defeated her while she was on her way to stop Vertigo.
He left a message for the Green Arrow with her - that the Arrow could accept his supreme reign over Seattle or die. Later, Dragon assembles a group of villains, the Longbow Hunters, to collect the bounty on the Green Arrow's head.
Green Arrow is able to defeat all of them with the help of his young half-sister, Emiko. Green Arrow is then reunited with Diggle, after Dragon attempts to kill the latter by defenestration. In a fight against both Arrow and Diggle, Dragon is able to significantly injure both of them but is ultimately defeated.
