"Victory Unintentional" is a humorous science fiction short story by American writer Isaac Asimov, published in the August 1942 issue of Super Science Stories and included in the collections The Rest of the Robots (1964) and The Complete Robot (1982). Background Written in January and February 1942, "Victory Unintentional" is a sequel to a non-robot story, "Not Final!". John W. Campbell of Astounding Science Fiction so disliked the story that he rejected it with the chemical formula for butyl mercaptan. Campbell knew the chemistry graduate-student Asimov would understand this as saying that the story stunk. Asimov sold it to Super Science Stories in March, which published the story in August 1942. It was the last story he wrote for 14 months, as he became busy with graduate school, got a job at the Philadelphia Navy Yard, and met and married Gertrude Blugerman. Plot Human colonists on Ganymede send three extremely hardy and durable robots, ZZ One, ZZ Two, and ZZ Three, to explore the physically demanding surface of Jupiter and contact the Jovians. Initially they are greeted with hostile attempts, though it takes the robots some time to deduce the hostile nature of activities because the attacks are too feeble, but reproduce normal conditions on Earth (e.g., using oxygen to poison the robots). After the initial hostile encounters with both Jupiter's wildlife and the suspicious Jovians, the robots establish a line of communication and are taken on a tour of the Jovian civilization. They quickly discover that the Jovians have a vastly larger population than the humans, since Jupiter has a much greater surface area than Earth. The robots also realize that the Jovians are considerably more advanced scientifically, and that they have developed force field technology far beyond that of humanity. Moreover, the Jovians are culturally inclined to believe themselves superior to the extent that they consider all other life forms, including humans, "vermin". They arrogantly threaten to use their force field technology to leave Jupiter, in order to destroy humanity. However, as the tour proceeds, the robots repeatedly (and unintentionally) surprise the Jovians with their immunity to extremes of heat, cold and radiation. Because they use gamma radiation for close range vision, they even pose a danger to local microbes and the Jovians themselves. At the conclusion of the tour the Jovians return the robots to their spacecraft, only to be astonished that it does not need to
