History

Earth-One

On Earth-One it was accidentally created by Supergirl in an attempt to create an antidote to Kryptonite poisoning. X-Kryptonite temporarily endowed non-Kryptonians, such as Streaky the Supercat or Ellie Leeds, with Kryptonian-like super-powers.

Arrowverse

On Earth-Prime, X-Kryptonite is a naturally occurring but extremely rare and largely unknown form of Kryptonite. It can be found in multiple locations on Earth but the world's largest deposit is in Smallville, Kansas.[1] It is yellow in colour and can endow humans with some Kryptonian-like super-powers, although an outside catalyst (such as an explosion or intense heat) is required, simply being near or touching X-Kryptonite does not result in super-powers. The effects can be unstable and debilitating,[2] and even fatal in some extreme cases.[3]

Morgan Edge has developed a procedure to endow humans with Kryptonian superpowers using X-Kryptonite. Only people who have been exposed to trace amounts of X-Kryptonite over a long period are fully receptive to the procedure. The people of Smallville are the only viable subjects.[4] Humans who are granted Kryptonian powers by X-Kryptonite also become vulnerable to Green Kryptonite.[5]
