Wonder Woman#137(1963)

Wonder Woman and Steve Trevor find themselves, within the Robot Plane, drawn through space magnetically to a parallel Earth populated by robots. A robot Wonder Woman has seen Steve from afar and brought him to the robotic Paradise Island to be her lover, but she has no use for the human Wonder Woman. Steve, who has been hypnotized by the robots, rejects Wonder Woman in favor of her robot double. But the human heroine refuses to give him up, so the robot Queen Hippolyte proposes a series of tests, with the winner gaining Steve Trevor and the loser facing doom. The first test is a wrestling match, which ends in a draw, thanks to the robot Hippolyte's biased refereeing. The human Wonder Woman wins a race to the top of a skyscraper and a contest to find the way out of a darkened labyrinth. The last contest, a duel with swords, ensues, and Wonder Woman hears the Hippolyte robot saying that, if the human Wonder Woman wins, she will have her destroyed on grounds of harming royalty. The human Amazon does destroy her robotic opponent, but then disguises herself to look like the robot Wonder Woman. The robot Hippolyte surrenders Steve Trevor to her, completely ignorant of the ruse, until Wonder Woman takes off with Steve Trevor in her robot plane. When the robotic Amazons try to follow in spacecraft, they are destroyed in a meteor shower. Later, Steve Trevor shakes off his hypnotized spell, and does not recall anything of their adventure.
