In SUPERMAN #13, the Man of Steel finds himself testing his strength on machines under the direction of Dr. Veritas, a beautiful woman who designed the instruments gauging Superman's abilities. These machines are so powerful, in fact, that Superman feels exhausted and actually begins to perspire for the first time since he can remember. But does the fact that he and Dr. Vertias have known each other for a while mean that they can trust one another? After all, why is she collecting all this data on Superman in the first place?
