|Debut||Curse of the Blood Rubies (December 1986)|
Gurumes is the king of his own land, the Land of Gurumes. Shortly after discovering that the deposits beneath his country harbored priceless blood rubies, he begins mutating into an obese horror with a virtually unsatisfiable appetite. This leads to his actions becoming corrupt in nature, as he continues ordering excavation of the blood rubies in order to fund a plethora of the world's greatest cuisines in a desperate attempt to cure his essentially painful hunger. Eventually, Gurumes comes to the conclusion that only the eternal dragon Shenron has the power "to wish [his] hunger away."
When the story of Curse of the Blood Rubies begins, Gurumes has four Dragon Balls in his possession. Early in the film, his two most esteemed henchmen, Raven and Bongo, confiscate Goku's Four-Star Dragon Ball from his home without his knowledge, leaving decent payment in its place. This causes Goku and Bulma, who is a passionate hunter of the artifacts, to seek out the two minions throughout the remainder of the film. During their adventure Goku and Bulma make several acquaintances, among them Penny, a girl native to the Land of Gurumes who seeks the assistance of Master Roshi in overthrowing the selfish tyrant to rescue her decaying land.
At the climax of the film, Shenron is summoned whilst the seven Dragon Balls are gathered inside Gurumes' stomach; the ray of light emitted by the Balls during the summoning process explodes through his mouth, destroying the upper floors of his castle. Penny requests that the Eternal Dragon restore her land's former peace and beauty, and thus Shenron removes the blood rubies from the deposits beneath the region (the dialogue between Penny and Shenron during the wish-granting sequence varies between the two versions of the film, but the result does not deviate between the two). It is also shown that Shenron's actions have re-granted Gurumes his human form, and ultimately his appetite is cured when Penny hands him a common apple, its simplicity shocking the king.
