The Green Dragon is a boss-fight from the video-game Lunar: The Silver Star Story.

When the thief known as Dross escapes into the underground maze behind his store the heroes pursue him in order to retrieve the Dragon Diamond, a valuable gemstone that he had stolen from them via trickery - however when they caught up with him Dross unleashed his "pet" dragon on them in the hopes it would dispose of them.

However despite being large and capable of breathing fire the Green Dragon was defeated and presumably slain by the heroes, leaving a defenceless Dross to surrender to the heroes.
