Part 2: "The Broken Code"

Synopsis:
Brainiac designs and builds a female robot named Genia. He sends the robot to replace a UN dilplomat, Madam Tru. The disguised robot then manipulates Superman and Batman into placing shrinking devices around large cities. Brainiac intends to steal the cities after shrinking them. However, Superman learns that Genia is a robot and foils her plot. After Brainiac escapes, Superman and Batman decide to exile the female robot. Batman tries to send her to the Phantom Zone, but Superman sends her to Kandor to be reprogrammed instead.
