Mr. Moss is the Head Prison Officer of Terra Zartacla. He is first seen in the episode "Escape" when he chases Aerrow deep into the jungle only for Aerrow to slip away, make a dent in Moss's prize Heli-Blade, "Bessy" and leave his prison empty. Ever since, Mr. Moss has held a grudge against Aerrow. His second appearance was on the episode "The Last Stand" when he summoned a group of Fire-Scorpions to attack the Storm Hawks while the Condor was stranded and overheated in the Wasteland. Mr. Moss and Hamish are presumably eaten by Fire Scorpions. He makes a cameo in A Colonel of Truth when he and Hamish are webbed up by the Colonel when the Storm Hawks make the gangster break out the prisoners in Zartacla (most of whom the Colonel had put there).
