Kryptonite is a fictional material from the Superman mythos — the ore form of a radioactive element from Superman's home planet of Krypton.

Originating in the Superman radio show series, the material is usually shown as having been created from the radioactive remains of Superman's native planet Krypton, and generally has detrimental effects on Superman and other Kryptonians.

A forerunner of the kryptonite concept was the unpublished 1940 story " The K-Metal from Krypton ", by Superman co-creator Jerry Siegel.

The K-metal in the story was a piece of Krypton which robbed Superman of his strength while giving humans superhuman powers, a plot point which decades later made its way into the TV series Smallville.

" Kryptonite " was introduced in June 1943 on the Superman radio series, in the story arc " The Meteor from Krypton ".

When Superman followed the time trail of a piece of red rock that weakened him, he was able to trace his origin back to Krypton for the first time.

In an effort to reduce the use of kryptonite in Superman storylines, all known kryptonite on Earth was transmuted into " k-iron " in a 1971 storyline titled " The Sandman Saga ", though kryptonite could still be synthetically manufactured by a variety of known and unknown means, and additional material left over from the destruction of Krypton would continue to fall from space.

By the events told in the New Krypton storyline however, several Superman villains, like Metallo and Reactron, have acquired some kryptonite samples to use against the Kryptonians on Earth.

Lex is later revealed to have obtained contact with the " Collector of Worlds " through unknown means and was told to say the word " Krypton " to Superman.

Krypton is a fictional planet in the DC Comics universe, and the native world of the super-heroes Superman and, in some tellings, Supergirl and Krypto the Superdog.

As originally depicted, all the civilizations and races of Krypton perished in the explosion, except for one survivor: the baby Kal-El who was placed in an escape rocket by his father, Jor-El, and sent to the planet Earth, where he grew up to become Superman.

Soon, beginning in the Superman comic strip, Krypton was shown to have been a planet similar to Earth, older by eons and possessed of all the beneficial progress that implied ( though the downside was the hint that Krypton exploded due mainly to old age ).

The debut of the Superman newspaper comic strip in 1939 also delved into further details about Krypton, including introducing the idea that all Kryptonians possessed a level of heightened physical abilities, including super-strength and super-speed.

However, after the introduction of DC's multiverse in the 1960s, this version of Krypton was declared to be the Krypton of the Earth-Two universe ( the native dimension of DC's Golden Age characters ) and its Superman.

In the Golden Age, Superman was unaware initially of his true origins ; in Superman # 61, Superman discovered the existence of Krypton for the first time and learned of his Kryptonian heritage.
