Superman Robot 15
The criminal Barkh and his gang capture the Superman Robot 15 in order to try to discover the tomb of the mysterious ancient Malis. When they are defeated by Superman, Superman Robot 15 is retired due to malfunctions (WF No. 202, May 1971: “Vengeance of the Tomb-Thing!â€). This adventure convinces the Man of Steel that the effects of atmospheric pollution on Earth are harmful to his robots and he begins to deactivate them from service (see Superman Robots).
