Lotor sets up on the Sand Planet, with Haggar's plans to transform the thriving, small, pure natives into robotically-charged menaces. Coran's friend, Professor Sarwa, contacts the Voltron Force with the news and calls them to come help just before he disappears on his study-tour there. They meet him and are charmed by the amusing Sand People. But Lotor arrives and uses nature against them to prevent them from taking a group hostage, and transforming them to fight his enemies as well.
