It was a transuranian substance that was found naturally under its crystalline form. There were several varieties of kryptonite, classified by color. There were two major sources of kryptonite in the Beta Quadrant: Kevratas and a planet on the border of the Lyran Star Empire called Krypton. There were several kryptonite varieties, black, red, green, orange, blue, white and pink being discovered before the RIS Bouteina surveyed Krypton for kryptonite deposits. All variants known as of 2385 were radioactive. (RIS Bouteina: "Sphere of Influence")
- As the events of Sphere of Influence seem to depict kryptonite as it is in Superman, Sphere of Influence thus implies that the Hypersonic series were the elements in the island of stability in the RIS Bouteina continuity. Thus it is assumed, for both RIS Bouteina and Star Trek: False Vacuum, that kryptonite's atomic number is 126.
Effects of kryptoniteEdit
A shipment of white kryptonite was smuggled by Klingon pirates aboard the IKS Gomex'Zha in 2415. White kryptonite was illegal in the Federation and the Interstellar Concordium by that time. (Star Trek: False Vacuum: "Black Tornado")
