Green dragon
Green dragons are a type of chromatic dragon. Their horns are little more than short spikes, but they have a long, fin-like crest running from the top of their head down the back of their neck.
Green dragons live in forests, consisting on a steady diet of woodland creatures. They are famously ill-tempered, and most mortals unfortunate enough to stumble upon their territory fall prey to the deadly, poisonous gas they can exhale. They are also, however, infamous schemers; masters of politics and intrigue. Their lust for treasure is rivaled by their lust for power, and many green dragon has been known to secretly take control of towns or cities through manipulation of their leaders - there has even been at least one recorded instance of an entire kingdom secretly being ruled by a particularly crafty green dragon.
