Alien scientist NamTar (enacted by Adrian Getley, with voice provided by Julian Gartner) offers to show Zhaan (Virginia Hey), D'Argo (Anthony Simcoe), and Rygel (Jonathan Hardy) the way back to their various homeworlds. In exchange, NamTar demands one of Pilot's arms. At first agreeable, the three crew members uncontrollably lapse into blatant hostility and greed -- while Aeryn (Claudia Black) learns the hard way that NamTar has a hidden agenda. "DNA Mad Scientist" was first telecast on June 18, 1999. ~ Hal Erickson, Rovi
