History[]
Superman: The Movie[]
Lex Luthor and his cronies Eve Teschmacher and Otis track a large chunk to Addis Ababa, Ethiopia, where they steal it from a museum under the cover of night. In this film's usage, the term "kryptonite" seems to mean simply a "Kryptonian meteorite". After co-opting and launching two missiles for opposite ends of the United States, Luthor places the kryptonite on a chain around Superman's neck and drops him into a swimming pool. When Teschmacher learns that one of the missiles is headed for Hackensack, New Jersey (where her mother lives), she rescues Superman from drowning and removes the kryptonite, after which his strength and powers quickly return.
Superman III[]
Billionaire Ross Webster orders the creation of synthetic kryptonite after remembering a Daily Planet story about the last original chunk disappearing years earlier after falling to Earth. After scanning the coordinates of Krypton's former location via satellite, computer programmer Gus Gorman determines that kryptonite is "an intense heat fusion" of; 15.08% plutonium, 18.06% tantalum, 27.71% xenon, 24.02% promethium, 10.62% dialium (which is a plant genus, not an element) 3.94% mercury, with the last 0.57% being an unknown element not found on the periodic table. The substitution of tar (which Gorman used after glancing at a pack of cigarettes) for the crucial, but unknown, component resulted in the synthetic kryptonite - like black kryptonite in the DC comics - turning Superman evil and eventually splitting him into two people. Retaining Superman's remaining good qualities, Clark Kent defeats the dark Superman, who vanishes. Later in the film, Gorman's creation, the Ultimate Computer, severely weakens Superman with a Kryptonite ray before Gorman has a change of heart and attacks his own machine.
