| Synopsis | Luthor takes a liquid kryptonite serum which makes it impossible for Superman to get near him. Superman makes a lead suit to protect himself, but Luthor has discovered a way to turn lead into glass. Eventually, Superman tricks Luthor into thinking he has become immune to Luthor's kryptonite radiations and Luthor takes an antidote, leaving himself open to capture. |
