The Green dragon is a rarely appearing monster in the Dragon Quest series. Introduced in the original game, they are powerful, scaly beasts of legendary status.
In appearance, green dragons are quadrupedal and wingless, their underbellies an orange-brown shade. Like dragons in most other tales, green dragons are powerful, boasting impressive stamina, strength, and resilience, as well as the ability to breath fire.
While this monster can be found in the overworld, a specific one is guarding Princess Gwaelin in the Quagmire Cave, and must be fought to rescue her. This green dragon was no different from it's brethren originally, but was given a full boss promotion in the remakes.
Only one wild green dragon can be encountered in the game, guarding a treasure room within Palaish Isle's shrine. It is important to save at a scout post beforehand if attempting to scout this green dragon, seeing as how it does not respawn once defeated.
