Member of the King Vega royal guard, Gorman is an arrogant officer always feeling superior to Gandal and blaki, both currently in charge of defeating Duke fleed and his friends. Coming on the Vegan moon base for only one purpose, showing that he can defeat grendizer easily and demonstrate the weakness of blaki.
Indeed, Gorman is a very capable fighter, extremely well trained, and during the fight Gorman piloting GIN GIN did place duke fleed and his Grendizer in a difficult situation, but lost the fight, as mad jealous, blaki, ordered vegan fighters to fire at gin gin in the back, making the fight much easier for duke Fleed.
