Karg is a villain in the Masters of the Universe franchise. He only appears in the 1987 live-action film and a few comics. In the movie, he was played by Robert Towers.
Live-Action Film
Karg is a mercenary serving Skeletor on Eternia. He is short with reptilian features, batlike ears, sharp teeth and long white hair. He dresses entirely in black except for a stoll trimmed in white fur. He is missing his left hand, having lost it at some point prior to the events of the film and replaced it with a hook. He is rather dim and not particularly brave, more than once showing great fear and cowardice in battle.
He appears first out of the mercenaries, leading a group of troopers to try and recapture Gwildor after he has been helped by He-Man. However, Gwildor and his rescuers escape from Karg and his troops by slipping through a secret passage in the inventor's home. Karg angrily yells for his men to tear the place apart. Later, after it turns out that He-Man and his friends have used the Cosmic Key to go to Earth, Karg is told to take a team consisting of himself, Blade, Beastman, Saurod and three troopers to retrieve the Key, kill all of He-Man's friends and return with the heroic warrior as a prisoner. Upon arriving, the villains find only high school student Julie Winston and Carl the school janitor. Beastman attacks Carl, beating him up, despite Karg yelling for him not to kill him. When Beastman throws the janitor through a door, revealing Julie, Karg decides Julie would make a better captive and orders her captured.
Fleeing the school, Julie is rescued by He-Man, who fights the mercenary team, killing the three troopers they brought with them. Thanks largely to Karg's cowardice, the group fails miserably. Even though they outnumber He-Man, Karg orders a retreat back to Eternia after a short battle.
Back on Eternia, Karg lies to Skeletor and says he and his team were outnumbered. An enraged Skeletor kills Saurod, and Karg and the other two are saved only by the intervention of Evil-Lyn. She goes back to Earth with them, and quickly reveals Karg's lie by using a device to scan the past, showing the recent fight, revealing that He-Man and He-Man alone defeated the mercenaries long before the other heroic fighters arrived and drove them away. Karg growls at her angrily. Following this, Karg falls out of favor with her, with the more competent Blade serving as Evil-Lyn's second in command on Earth. Karg manages to get himself back into her good graces, however, by finding a photograph of Julie with her parents, which gives Evil-Lyn the idea to impersonate Julie's mother to steal the Cosmic Key.
After He-Man's capture, Karg returns with the other villains to Eternia, where he witnesses Skeletor's transformation into Master of the Universe using the Sword of Grayskull. Following the sudden appearance of He-Man's friends, who teleport into the throne room using the Cosmic Key, Karg shoots at them. When Evil-Lyn decides to abandon Skeletor, Karg tried to persuade her to stay and help him, but she refuses, and so Karg winds up escaping with her and Beastman before Skeletor is defeated by He-Man.
