Clark Kent after he went missing (actually kidnapped and brainwashed by Darkseid). However, Lex Luthor had known for some time that Superman was a robot. In the Justice League episode "A Better World", the alternate Earth of the "Justice Lords" is shown to have its own version of Arkham Asylum, populated by several members of Batman's rogues gallery. All the inmates have been lobotomized by that world's Superman, and any hostilities are dealt with by a contingent of Superman robots. They are dressed the same as that world's Superman, featuring a black, white and red color scheme. When the "good" Wonder Woman fails to give the correct password, a lobotomized Joker triggers an alarm, and several robots battle the League members present. In the Legion of Super Heroes episode "Message in a Bottle", a damaged Superman robot was seen in the abandoned Fortress of Solitude, resembling the Cyborg Superman. In one episode of the Krypto the Superdog animated series, a Kryptonian construct called "Dogbot" was painted to resemble Krypto, and, as "Superdogbot", filled in for the real thing for a short time. The Superman robots appear in the Justice League Action episode "Battle for the Bottled City". They appear as one of the defenses of the Fortress of Solitude at the time when Brainiac plans to reclaim the bottled city of Kandor that was taken from him back in "Plastic Man Saves the World". Brainiac manages to destroy some of them. One Superman robot was piloted by Atom in order to fight and defeat Brainiac. Film In Superman: Doomsday, a Superman robot (voiced by Tom Kenny) features quite prominently in the plot. The Superman robot has a very mechanical design, the only resemblance to Superman being the "S" logo on its chest. The robot is seen in the beginning of the film, maintaining the Fortress of Solitude, and providing Superman and Lois, information on "Doomsday". After Superman's apparent death, the robot rescues Superman's comatose body from Lex Luthor's building and brings Superman back to the Fortress to nurse him back to health. The robot is referred to simply as "The Robot", and plays a role similar to the Eradicator. In All-Star Superman, based on the acclaimed storyline by Grant Morrison, the Robots fill the same role as in the books, except one of the differences is that the robots have their numbers on their symbols, instead of the usual Superman
