The Gasbagon is a recurring monster in the Dragon Quest series, first appearing in Dragon Quest VI. It is a bloated, orange dragon resembling a balloon with a long, corked tail taking the place of a string.
Gasbagons are rotund dragons with orange spotted scales, beige undersides, and long tails ending in a cork. They have a singular purple eye, long snouts, and purple tongues. These air-sailing drakes will drop on party members and smother them, dealing heavy damage. They're also capable of flaming the party with a fierce fire. The dragons are also capable of sacrificing themselves by violently exploding to harm parties of adventurers. After their original appearance in VI, gasbagons have only appeared in spinoff games in the series.
Gasbagon appears as an A-rank monster of the Dragon family as part of the limited Dragon Fest event. It will join the player in Chapter 1, Episode 5 of the event quests and it stars in its own Battle Road. There is also a gasbagon named Gaston who runs a hot-air balloon business, transporting characters throughout the world of Orchesterra.
