Anyway, we find out in "Blue Magic" that Flash is the spitting image of Azura's long-departed lover, named "Gor-Don." You see, "Gor-Don" was once the all-powerful ruler of Mongo, a sort of Alexander the Great figure. He ruled the planet wisely with Azura as his mate, but then he left to conquer other worlds and his high priest - Ming the Merciless - seized power on Mongo. Ming once attempted to defeat Azura but she used her magical powers to destroy his million-man army. Now, Ming gives Azura a wide latitude and no longer attempts to conquer her domain.
In this episode, Azura, who commands the "Blue Fire Worms," captures Flash, Thun, Zarkov and Dale while they are still riding the railroad back to Arboria (from Fridgia) to rendezvous with Barin and Vultan. Inconvenient that the rocket rail passes right through her kingdom. But anyway, the captives are ushered into the blue cavern kingdom on a magic carpet (by a wizard.) Then Zarkov, Thun and Dale are entrapped in a giant crystal ball, as Azura imposes the personality of Gor-Don upon Flash with a "memory crystal," thereby making him forget his friends and become her consort. Hubba-hubba.
But Zarkov, realizing that "knowledge is the sharpest weapon of all," manages to outfox the evil wizard minion, and he and the others race to stop Flash as the earther leads Azura's army (on a chariot, no less...) into battle against Barin and Vultan, who have come to his rescue.
Next week: "King Flash!"
