In the mirror universe, the Tantalus Field is an alien device that vaporizes victims at the touch of a button. James Kirk used it to become captain of the ISS Enterprise. (TOS episode: "Mirror, Mirror") It was one of the secrets that Tiberius was able to gain from the First Federation representative Balok before he was killed. (TOS novel: Dark Victory)

Spock took possession of the device upon his assassination of Kirk and used it to eliminate his political enemies, including a mutinous Uhura and Empress Hoshi Sato III. (TOS novel: The Sorrows of Empire)
