General Donald Morden is the main antagonist of the "Metal Slug" franchise. He is depicted as a rambling madman wearing a beret, eyepatch, and wearing his army's uniform. In some games, he bears a passing resemblance to Saddam Hussein. He appears in every game except "Metal Slug 5." He apparently mends his ways by the end of "Metal Slug 6", as he (or Rootmars depending on the player(s)' chosen route) rescues the player(s) after they are knocked off a wall by an explosion caused by the alien end boss. His army is the main force of opposition in the Metal Slug games, with the exception of "Metal Slug" 5 and 6. He commands the Rebel Army, and in "Metal Slug 4" he was thought to be behind the Amadeus Terror Syndicate. He once again returns to his roots of attempted world domination in "Metal Slug 7", this time with the help of the Rebel Army from the future, also being the final boss for the first time since the original "Metal Slug". Like the main characters, General Morden appears in various SNK games as a cameo, especially in the "" series.
