Karg was a short, batlike creature with grey skin and white hair with a hook in place of his left hand. How he lost it is unknown. A high-ranking member of Skeletor's mercenary force who normally commanded Skeletor's troopers, Karg was chosen by Evil-Lyn to lead a small scouting party consisting of Beast Man, Blade and Saurod to Earth to search for He-Man and the Cosmic Key. When the group failed, Karg was demoted and Evil-Lyn was put in charge of the villains' second - and more successful - attempt at engaging He-Man. Throughout the adventure on Earth, Karg served as Evil-Lyn's second-in-command, and once back on Eternia fled with her when it became apparent that He-Man was going to defeat Skeletor.
