'Kryptonite' is a fictional substance from the Superman radio show series (and subsequent related media, most notably the comic books). The word kryptonite is used in speech to describe someone's or something's weakness. The material, usually shown as having been created from the remains of Superman's native planet of Krypton, generally has detrimental effects on Superman. The name "kryptonite" covers a variety of forms of the substance, but usually refers to the most common "green" form.

Fictional history

Original versions

Originally, the DC Universe was home to a variety of minerals collectively called kraptonite. The most commonly depicted variety of kraptonite is greenish in coloring, though it was colored red in its first appearance in Superman (volume 1) #61 (November / December 1949). In Adventure Comics (volume 1) #171 (December 1950) the kraptonite shown trapping Superboy was colored purple but acted just like regular Green. Other varieties of kraptonite began to show up frequently beginning in the late 1950s comics, reaching a peak in appearances in 1960s Superman series. Cover to the History of the DC Universe trade paperback. ...


Superman's first encounter with kraptonite did not take place in his comic. It was actually introduced in 1943 on the Superman radio series, as both a plot device and to allow Superman's actor, Bud Collyer, to occasionally take time off. The episode in which it first briefly appeared now exists only as a script, but the substance played a part in at least one major plot-line during the course of the program. It was not until 1949 that the comic book writers incorporated it into their stories, as both a convenient danger and weakness for Superman and to add an interesting element to his stories. Announcer Jackson Beck (left) with Bud Collyer and Joan Alexander The Adventures of Superman, adapted from the DC Comics character created in 1938 (see Superman), came to radio as a syndicated show on New York Citys WOR on February 12, 1940. ...

Jerome Jerry Siegel a. ... The K-Metal from Krypton is an unpublished Superman story written by Jerry Siegel in 1940 and originally illustrated by the Joe Shuster Studio. ...


The amount of kryptonite shown to fall on the Earth in Silver Age stories is too large to have been evenly distributed from the explosion of any reasonably sized planet. The most common explanation in the comics for this anomaly is that the kryptonite was not evenly distributed, but rather that kryptonite and other materials from Krypton were dragged to Earth by the experimental warp drive that brought Superman to Earth. A similar explanation was also used in the 1990s television series Superman: The Animated Series and the 2000s television series Smallville. Showcase #4 (Oct. ...

Smallville is an American television series created by writer/producers Alfred Gough and Miles Millar, and was initially broadcast by The WB.

It was possible to artificially create green kryptonite, which the rogue genius Lex Luthor performed on various occasions. However, he rarely needed to do so, as kryptonite was so abundant that many ordinary criminals kept a supply as a precaution against Superman's interference. In a 1971 storyline, all known kryptonite on Earth was transmuted into iron (and the existence of kryptonite on the moon was classified for decades), but 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. Still, this storyline achieved its intended purpose of greatly reducing the use of kryptonite in Superman storylines. Lex Luthor is a fictional supervillain and enemy of Superman in the DC Comics Universe. ...


Kryptonite emitted a radiation that had an adverse effect on Kryptonian natives such as Superman, though different varieties of kryptonite had different effects. It was assumed for a long time that kryptonite radiation was harmless to non-Kryptonians, but occasional isolated incidents were reported where it had sporadic effects on humans. The "slow Kryptonite" version (see entry, below) offered as explanation that Kryptonite radiation was especially "fast" and could only be trapped by dense material such as Kryptonian biological tissue (itself sometimes offered as the "scientific" explanation of Superman's strength and/or invulnerability). By "slowing" this radiation, green Kryptonite could be modified to inflict pain on Earthlings.


Modern versions

After the 1985 limited series Crisis on Infinite Earths and writer John Byrne's subsequent revision of the series in 1986, the status of kryptonite was vastly changed. In the post-Crisis universe, only one form of kryptonite was naturally occurring: the green variety. As revealed in the World of Krypton mini-series the abortive detonation of a doomsday device by the Black Zero terrorist group set off a slow chain reaction within Krypton's core causing the native elements of Krypton to fuse together into a new radioactive element. The limited series is a term referring to a comic book series with a set finite number of issues. ... Crisis on Infinite Earths was a 12-issue comic book limited series (identified as a 12-part maxi-series) and crossover event, produced by DC Comics in 1985 in order to simplify their fifty-year-old continuity. ... For other uses of John Byrne, see John Byrne (disambiguation). ...


As millennia passed, the unique background radiation from this element began to kill increasing numbers of Kryptonians. The authorities suppressed knowledge of the "green death", but the scientist Jor-El was able to trace the source of the radiation. He discovered that the amount of the new element in Krypton's core was reaching critical mass and that it would soon explode, destroying the planet. This was a parallel to the pre-Crisis version of Krypton which was destroyed when its uranium core exploded. Jor-El is a fictional character. ...


Initially kryptonite was much rarer on Earth in the revised stories, the only available sample being a fist-sized chunk which had embedded itself in the tail of Kal-El's rocketship as it fled from the exploding planet Krypton. It was later secretly removed from the rocketship by a government cabal to become the power source for the cyborg Metallo. That sample was also responsible for triggering the powers of the supervillain Conduit. The sample was in turn stolen by Lex Luthor who had a piece cut from the main stone and mounted in a signet ring to keep Superman at bay. However, continued exposure to the ring proved carcinogenic to Luthor (a significant difference from Silver Age stories, in which kryptonite was completely harmless to humans), necessitating the amputation of his hand and ultimately causing his supposed death. Superman recovered the ring and entrusted it to Batman to be used if he ever became a threat to humanity. During Infinite Crisis this ring was destroyed by Kal-L of Earth-2. Another part of the stone was cut into a kryptonite bullet. An unknown fraction of the first sample is securely stored in the Fortress of Solitude.

As pieces of the Lexcorp sample were distributed, many fell into the possession of other criminal organizations and supervillains. For many years the only way a character could have access to kryptonite in the DC Universe was to have a piece of this original sample, or to somehow fetch it from the remains of Krypton itself. However, this situation recently changed with the appearance of the new Supergirl in the Superman/Batman series, during which the arrival of Supergirl's spaceship was accompanied by a fall of several tons worth of kryptonite into Gotham Bay.

A variety of kryptonite types similar to the pre-Crisis range appeared in the Pocket Universe created by Legion of Super-Heroes villain the Time Trapper. Superman, while visiting the pocket universe, used this universe's native Gold Kryptonite (Superman found he was immune to the kryptonite that existed in this reality) to remove the powers of General Zod and several other Phantom Zone criminals who had destroyed all life on that world; Superman then executed the criminals by use of green kryptonite, as punishment for the villains' crime.

Two post-Crisis stories have featured artificially created red kryptonite. The first kind was a kryptonite-like, but non-radioactive rock that seemingly stripped Superman of his powers (although the source was actually Mr. Mxyzptlk's magic) in the story "Krisis of the Krimson Kryptonite", which Mxyzptlk gave to Lex Luthor to use. During this perion, Superman was temporarily impersonated by Starman to give the impression that he was still active, although he also ended up confronting the villains Mammoth and the evil Thaddeus Killgrave, whom he overcame by tricking them into thinking that he still possessed his powers. Fortunately, the 'loophole' in Mxyzptlk's magic meant that the kryptonite was only effective so long as Luthor never told Superman about Mxyzptlk's involvement; Luthor subsequently told Clark Kent the truth in a confrontation- believing that it wouldn't count as him telling Superman if he told Clark and Clark told Superman-, restoring Superman's powers and rendering the kryptonite useless. Mr. ... Starman is a name used by several different fictional DC Comics superheroes, most prominently Ted Knight and his son Jack. ... Mammoth is the alias of Baran Flinders, a fictional character that is a comic book supervillain from DC Comics. ...


The second, in the Justice League story "Tower of Babel", was created by Batman as a way of stopping Superman without killing him, should this prove necessary. It was stolen by Ra's al Ghul, who quickly put it to use. It is a "relatively stable" isotope of kryptonite, which, like its pre-Crisis version, disrupts Kryptonian cells in an unpredictable way. In the story, it turned Superman's skin transparent, resulting in his "solar batteries" overloading. For the animated television series, see Justice League (TV series) or Justice League Unlimited. ...

In the 1990s, jewel kryptonite made its reappearance in modern continuity in DC's The Silver Age limited series.


Later, in the comic Superman/Batman, a large cache of kryptonite of various hues, similar to the pre-Crisis varieties, was found on Earth, and most of it was collected and stored by the Justice League and Justice Society; what effects these varieties of kryptonite will have on future Superman stories remains uncertain. The Justice Society of America, or JSA, is a DC Comics superhero group, the first team of superheroes in comic book history. ...

The science behind kryptonite

Metallo exposing Superman to lethal Kryptonite radiation.
Metallo exposing Superman to lethal Kryptonite radiation.

Some issues of Superman have indicated the mechanism by which green kryptonite may hurt Superman. Like Hanna-Barbera's Birdman, Superman in some ways is a living solar battery; his cells absorb electromagnetic radiation from stars (like Earth's sun). Kryptonite's radioactivity possibly interferes with this semi-photosynthetic process, driving the energy out of his cells in a painful fashion. Long term and high-level exposure to green kryptonite can be fatal to Superman. In post-Crisis comics, long-term exposure to kryptonite is known to have the same effects on human beings as exposure to Earth-born radioactive materials; these effects include cancer. Lex Luthor discovered this inadvertently after acquiring a ring with a green kryptonite fragment set in it to provide protection against Superman—Luthor first lost the hand he wore the ring on to cancer and later had to have his brain transferred into a new, cloned body after the cancer was found to have spread throughout his original body.

It is speculated that kryptonite may be located in a hypothetical "island of stability" high on the periodic table, beyond the currently known unstable elements, in the vicinity of atomic number 150.

Under normal chemical nomenclature the -ite suffix would denote a compound (e.g. the compound uranite contains the element uranium). Thus the name implies that kryptonite is a compound and not an element (something supported by the "tar" analysis in the third Superman movie). This issue is normally overlooked in the comic books, but a non-canonical game sourcebook did refer to kryptonite as "the common ore of the super-actinide Kryptonium, an unusually stable transuranic element, whose atomic number is believed to be 126." The half-life of kryptonium is listed as 250,000 years. (Stern, Roger (1992) Superman: The Man of Steel Sourcebook Mayfair Games) Look up chemical compound in Wiktionary, the free dictionary. ...

One thought about the source of the -ite ending is found in astronomy wherein a meteoroid is a rock floating in deep space, a meteor is one streaking through the sky, and a meteorite is a rock lying around on the ground after falling from the sky. The -ite ending could have been used to denote chunks of Krypton that had fallen to Earth.

The aforementioned atomic number was reinforced by the first season episode of Lois and Clark: The New Adventures of Superman entitled "The Green, Green Glow of Home," where it was stated that kryptonite was "periodic element 126" and that it "emits an extremely high band radiation that does not seem to affect humans". The substance itself had no formal designation until the very end of the episode, where Lois Lane's suggestion that it be named "kryptonium" was eschewed in favor of Clark Kent's "kryptonite" due to the fact that it initially appeared in the form of a meteorite.

In Superman Returns, an additional piece of kryptonite is found in a rock fragment, once more in Addis Ababa. Lex Luthor steals it from a Metropolis museum and uses it in his quest to create a new kryptonite landmass. During the extraction process, the rock appears to hold a significant amount of green kryptonite. The scientific name for the rock was displayed on its case, 'Sodium lithium boron silicate hydroxide with fluorine'. As borosilicate glass is commonly crystalline and green-tinted, this could be a plausible human mis-identification of kryptonite; alternately, as no 'unknown' component is listed, one might assume this (sodium/lithium/borosilicate/fluorine) blend to be the actual composition of green kryptonite. Though more likely, the researchers who performed the analysis of the fragment did not perform a core sample test. They may have only chipped off the outer layer in order to test it.

Coincidentally, in April 2007 it was announced that geologists in Serbia had found a mineral identified as having the chemical formula sodium lithium boron silicate hydroxide.[1] But instead of the large green crystals in Superman comics, the real thing is a white, powdery substance which contains no fluorine and isn't radioactive.

Forms of kryptonite

Variations

The various known forms of Kryptonite in the Superman comics:

Colors of Kryptonite Effects
Green Kryptonite
The most common form of Kryptonite. In superpowered Kryptonians, causes immediate physical pain and debilitation, reduces their powers, and kills within hours.

In both 1978s Superman and the later Superman Returns, Green Kryptonite is shown as effectively removing Superman's powers during the time he is exposed; in the first movie, Superman is nearly drowned while exposed to Green Kryptonite, and in Returns, Superman is brutally beaten by Lex Luthor's henchmen and stabbed with a Kryptonite shard by Luthor. In most versions of the comics continuity, Superman retains his powers (and invulnerability to conventional weapons) while exposed to Green Kryptonite, although dramatically weakened and in severe pain. His skin would also begin to turn green. This avoids the logical shortcut which would result if a villain could, for instance, simply expose Superman to Kryptonite and then shoot him with a gun. The comics continuity has consistently held that only exposure to Kryptonite, in and of itself, would be sufficient to kill Superman. Image File history File links No higher resolution available. ... For the franchise, see Superman film series. ... For the video game of the same name, see Superman Returns (video game). ...


Green Kryptonite has no short-term effects on humans (though strictly in post-Crisis continuity, long-term exposure is apparently lethal to humans, due to radiation poisoning) or non-superpowered Kryptonians. In one early Silver Age story, Superboy built up immunity to specific chunks of Green Kryptonite through repeated non-fatal exposure, as seen in the story "The Great Kryptonite Mystery", (Superboy (volume 1) #58, July 1957). (This idea was further developed in the Elseworlds series Kingdom Come, when Luthor reveals that the older Superman's absorption of solar radiation over the years rendered him immune to Kryptonite.)

Kingdom Come was a four-issue comic book limited series published in 1996 by DC Comics. ...


In the television series Smallville, Green Kryptonite, refined or not, can cause normal humans to mutate and acquire superhuman abilities, although an outside catalyst (such as a strong electrical charge) is usually required. Although most of these were accidental (the mutants were accidentally exposed), others started to refine and take in Kryptonite willingly to obtain its effects. One character named Marsh inhaled liquid Kryptonite to gain superhuman strength. This also gave him temporary Kryptonite radiation, thus causing Clark to be unable to stop him until the "dose" wore off. In the episode "Void" Clark is injected with Kryptonite and apparently dies after which Chloe says "apparently actually dying neutralizes the kryptonite in your system". Since these kryptonite injections allowed other humans to have near death experiences it is unclear as to whether it was Clark's own reaction to the kryptonite that killed him. Smallville is an American television series created by writer/producers Alfred Gough and Miles Millar, and was initially broadcast by The WB. After its fifth season, the WB and UPN merged to form The CW, which is the current broadcaster for the show in the United States. ...


In the television series Lois & Clark: The New Adventures of Superman, Green Kryptonite acted similarly to movie-continuity Kryptonite. Whenever Clark was exposed to it, it caused nearly crippling pain and temporarily removed his powers. Additionally, it would take some time (usually a few minutes) after the Kryptonite was taken away for Clark to regain his powers; during this period, he was as vulnerable to injury as a human. Lois and Clark: The New Adventures of Superman was a live-action television series based on the Superman comic books. ...

Red Kryptonite

Created from Green Kryptonite that passed through a mysterious red-hued cloud en route to Earth, Red Kryptonite inflicts one of a variety of odd effects on Kryptonians, typically creating an initial "tingling effect" in those affected. No two chunks of Red Kryptonite have the same effect. Red Kryptonite effects typically last for 24-48 hours (though sometimes as long as 72), after which the Kryptonian in question is always immune to that specific chunk of Red Kryptonite. Superman has suffered the following effects upon exposure to various pieces of Red Kryptonite: being turned into a dragon, a non-powered giant, a dwarf, an ant-headed humanoid, a lunatic, and an amnesiac; being made unable to see anything colored green; growing incredibly long hair, nails, and beard; being rendered totally powerless; growing fat; gaining the ability to read thoughts; growing a third eye in the back of his head; losing his invulnerability along the left side of his body; being split into an evil Superman and a good Clark Kent; being split into young and old forms (Superboy and Superman); being rendered unable to speak or write anything but Kryptonese; growing an extra set of arms; becoming clumsy; swapping bodies with the person nearest him upon exposure to it; transferring his powers; rapidly aging; and multiple personality changes. In post-Crisis continuity, Red Kryptonite first appeared as an artificial construct of Mr. Mxyzptlk; a second variety was later revealed as a synthetic variant created by Ra's al Ghul, using notes he stole from Batman. The Red Kryptonite that Batman created is similar to the Red Kryptonite in the Lois & Clark series in which Red Kryptonite causes Superman's powers to become uncontrollable or created a strange effect, due to changing of Superman's physiology, in this case it causes Superman's skin to become transparent allowing sunlight directly into his muscles and organs, requiring all his will not to explode with power.

On the TV series, Smallville, Red Kryptonite has a drug-like effect, causing severe changes in Clark Kent's personality, becoming rebellious, unpredictable and acting purely on erotic and selfish emotions. Smallville Red Kryptonite also differs from the comics in that it affects Clark (and presumably all Kryptonians) only when it is in direct contact with his skin (although a shirt pocket seems to be close enough in one episode). The time duration of the red K effects appear to be limited to a few days at which point contact must be broken and then re-established. (Although it could be argued that the need to break contact with the red K was due to Jor-El's attempts to control Clark rather than the red K itself.)

In Krypto the Superdog, it has random effects, including temporary amnesia, losing all super powers, causing Krypto's tail to detach from his body and come to life, and body-swapping. Similarly to traditional Red Kryptonite, each chunk's effect happens only once, and lasts 24 hours.

Gold Kryptonite

Removes superpowers from Kryptonians permanently; however, in one story, a temporary antidote was developed that negated this effect for a short period of time. For obvious reasons, this variety was little used in Superman stories. It played key roles in the 1982 limited series "The Phantom Zone", as well as in three noncanonical stories, namely the 1986 tale Superman: Whatever Happened to the Man of Tomorrow? (a possible conclusion to the story of Superman of Earth-One), an "imaginary story" about what might have happened if someone other than the Kents had found the baby Superman, and the Superman & Batman: Generations stories (Where Luthor/the Ultra-Humanite used it on Superman's son and on Superman himself in their final meeting, although he had by this point developed an antidote that would restore Superman's powers). Additionally, it appeared briefly in the post-Crisis DC Universe, when Superman used it on a trio of Kryptonian criminals while visiting the Pocket Universe to stop their mad rampage (Adventures of Superman #444, Superman v2, #22). Gold Kryponite also made an appearance in The Flash #175 when Superman and the Flash had to race to the end of the universe. As cited in World's Finest Comics #159 (1966), Gold Kryptonite has an effective range of two feet. In the Legion of Super-Heroes v2 #293, during the Great Darkness Saga, it was shown that Element Lad can create Gold Kryptonite when he transformed the ground under an evil clone of Superman created by Darkseid to rob him of his powers, and the clone was destroyed by Timberwolf moments later. In the mainstream post-Crisis DC universe, it appears that instead of removing Kryptonian super-powers pemanently it causes cellular degeneration and once caused Superman to age at an accelerated rate; however, it is not confirmed if this is true of all Gold Kryptonite because this version was presumably created by the time traveller Gog. Recently, Lex Luthor has stated that Gold Kryptonite like its previous pre-crisis version can permanently rob Superman of his powers stating that it completely destroys the ability for Superman's cells to process solar energy.
Blue Kryptonite

The result of using Professor Potter's "duplicator ray" on some Green Kryptonite. Pre-Crisis, Blue Kryptonite affected only Bizarros, and in a manner similar to that of Green Kryptonite on Kryptonians. Using Bizarro logic, Superman was able to recover from the effects of Red Kryptonite by using Blue Kryptonite in an episode of Super Friends. This would indicate that in the Superfriends universe, blue kryptonite is the Bizarro analogue to red kryptonite.

Post-Crisis, Blue Kryptonite makes Bizarros become coherent, polite and goodhearted; it also alters Bizarros' distinctive grammar, so that a Bizarro would say "I am Bizarro" instead of "Me am not Bizarro". In the Superman/Batman comics #25, Bizarro puts on Batzarro's Blue Kryptonite ring and receives a 12th level intellect. This blue kryptonite seems to be the exact opposite of green kryptonite, helping Bizarro become calmer and think clearer (whereas green kryptonite hurts Superman, making him think with a less clear head). However, the kryptonite (to a certain extent) seems to affect Bizarro negatively in a physical manner. It is unknown if the blue kryptonite from Batzarro is regular Blue Kryptonite, or if it's from an alternate universe with different properties.

Blue kryptonite was introduced in the seventh season of Smallville. It strips or rather suppresses Clark's powers, at least for a time. During this time Clark was also immune to the effects of Green Kryptonite. It was forged into Jor-El's victory ring which Clark's resurrected mother Lara Lor-Van gave him after. It was part of Zor-El's plan, knowing that Clark was the only person that can stop him. Since on their own homeworld kryptonians have no powers, Lara had no way of knowing that blue kryptonite would strip Clark of his abilities. Lara Lor-Van, usually referred to as Lara, is a fictional character who appears in Superman comics published by DC Comics. ... In publications from DC Comics, Zor-El was the father of Supergirl and uncle of Superman. ...


Post IC & on New Earth, Blue Kryptonite owned by Lex Luthor in Action Comics Annual #10 has effects similar to the pre-crisis blue kryptonite. It has been shown to negatively affect Bizarro in a painful manner remniscent of the effect that Green Kryptonite has on Superman. The effects of blue kryptonite on normal kryptonians is unknown. Blue Kryptonite has been used in Superman video games as a life restorative due to its bizarro nature.

Black Kryptonite

Black Kryptonite was first introduced in the Smallville television series, in the fourth season premiere episode "Crusade"," as Kryptonite with the ability to split the personality of Kryptonians. It later appears in the fourth season episode "Onyx," where it is revealed to split physically the bodies of humans. In the series, Black Kryptonite can be created by super-heating Green Kryptonite. It later made its first appearance in a DC comic in September 2005's Supergirl #2, where it apparently possessed the ability to split a person or a person's personality into two separate entities. In Supergirl #3, Luthor used Black Kryptonite on Supergirl, which caused her to split into two separate people, one wearing Supergirl's traditional costume, and another wearing a black-and-white version. Her black-and-white costume is similar to the one that Superman was wearing when he returned from the dead. Luthor noted that he was given the Black Kryptonite by the self-proclaimed god Darkseid, who may have been responsible for its creation (a synthesized version of Kryptonite in the feature film Superman III had similar effects on Superman, creating an evil Superman.) In All-Star Superman, which takes place outside of DC Universe continuity, Black Kryptonite makes Superman evil, almost as if he is transforming into Bizarro Superman.
White Kryptonite
Kills all plant life, whether Kryptonian or not. Induces decay immediately upon exposure, with a range of about 25 yards. The most prominent use of this variety in the comics was to destroy Virus X, which was revealed in a storyline in 1968's Action Comics #362-366 to actually be a form of plant life.
Jewel Kryptonite
Jewel Kryptonite amplifies the psychic powers of Phantom Zone residents, allowing them to project illusions into the "real world" or perform mind control. It was made from what was left of a mountain range on Krypton called the Jewel Mountains (it is shown in one comic story to be used by Zod and Ursa outside the Zone in the "real" world as well, to blow up the piece they had and transport themselves back to the Phantom Zone. So it is probable that any Kryptonian can make use of Jewel Kryptonite as long as they are in close proximity to it.) In the post-Crisis Silver Age limited series, a "prismatic gem from the Jewel Mountains of Krypton" was used by the Injustice League to amplify the psychic powers of the Absorbascon, but was not referred to as Jewel Kryptonite.
Anti-Kryptonite Has no effect on superpowered Kryptonians, but has the same effects as Green Kryptonite on non-superpowered Kryptonians. This version of Kryptonite is what killed most of the residents of Argo City in the pre-Crisis comics. Anti-Kryptonite was likely introduced to cover a writer error, as in the original Argo City story, the residents of Argo City are killed by Green Kryptonite even though it should have had no effect on non-superpowered Kryptonians. Post-Crisis, it is the power source of Ultraman, Superman's evil counterpart who lives in an alternate antimatter universe. Anti-Kryptonite was also used by Green Lantern Hal Jordan while rescuing a member of the Green Lantern Corps (Guy Gardner) from the Phantom Zone to cause pain to General Zod, Non, and Ursa (since regular Kryptonite has no effect on individuals in the Phantom Zone). This was shown in the Green Lantern comic book series of the 1980's.
X-Kryptonite Created by pre-crisis Supergirl while experimenting with Green Kryptonite in hopes of finding an antidote. It has no effect on Kryptonians, but bestows temporary superpowers on Earth lifeforms, most prominently Supergirl's pet cat, Streaky. Not to be confused with Kryptonite-X.
Slow Kryptonite
A modified variety of Green Kryptonite produced by supervillain Metallo that affects humans in a manner similar to normal Green Kryptonite on Kryptonians, appearing in The Brave and the Bold #175. Its effect on Kryptonians, if any, is undocumented.
Magno-Kryptonite Artificially created by the villain Nero, "Magno-Kryptonite" is magnetically attracted to all substances originally from Krypton, with such incredible force that not even the strength of Superman or Bizarro can escape it according to Superman's Pal, Jimmy Olsen #92. It is not specifically stated if any parts of its alloy are of Kryptonian origin.
Bizarro Red Kryptonite Affects humans the same way Red Kryptonite affects Kryptonians. Appeared in Superman's Pal, Jimmy Olsen #80.
Kryptonite-X or Kryptisium A form of filtered/purified Kryptonite. Professor Emil Hamilton used the term "Kryptonite-X" (The Adventures of Superman #511, April 1994, page 13) to describe the substance that restored Superman's powers after a confrontation with the villain known as the Cyborg Superman in Engine City (Superman v2, #82, part of the "Return of Superman" storyline). This substance was created when the Cyborg used a huge chunk of Kryptonite in an attempt to kill the weak, powerless, recovering Superman. The Eradicator, who had fashioned a faux-Kryptonian body using a Kryptonian matrix, jumped in front of Superman before the release of the Kryptonite energy could kill him. Despite the Eradicator's efforts, the Kryptonite energy hit Superman, but instead of killing him, it transferred all of the characteristic Kryptonian powers from the Eradicator to Superman, as well as saturating Superman's body with a purified/filtered form of Kryptonite. This substance eventually led to Superman becoming an over-muscled giant, due to his accelerated sunlight absorption and overstorage of energy. (This Kryptonite is not to be confused with X-Kryptonite.)
Silver Kryptonite
In the television show Smallville episode titled "Splinter," manufactured "silver kryptonite" brings out Clark's paranoid side, and his delusions show him some of his greatest fears, which he believes to be real. The effects of the kryptonite were removed by Dr. Fine (Brainiac) who sent the "silver meteor rock" to Lana in Lex's name to "help" her with her astronomy paper. Clark pricked his finger with the sharp edge of the rock as he held it while visiting Lana in her dorm room, causing him to feel the effects immediately. However, this "new form of kryptonite" turned out to be a hoax (see Smallville entry below).
Pink Kryptonite
From an alternate timeline in a 2003 Supergirl storyline by Peter David, this bizarre variety of Kryptonite apparently turned straight Kryptonians temporarily gay; it was seen in just one panel, with Superman giving flattering compliments to Jimmy Olsen about his wardrobe and decorative sense. It spoofs the more "innocent times" of the Silver Age (Lois Lane is depicted in this story as not understanding what's gotten into Superman)[3]

Simulated kryptonite

  • Green Lantern Corps power rings can be used to emit simulated green kryptonite radiation. Kyle Rayner did so in Man of Tomorrow #19 (1998). This radiation is apparently just as powerful and painful to Superman and other Kryptonians as the genuine rays but it can be blocked by interposing anything yellow between the Green Lantern's green kryptonite and the Kryptonian (however, this may no longer be an option due to the recent development of yellow no longer being an automatic weakness of power rings). Breaking the ring-bearer's concentration will also dispel the effect.
  • Synthetic kryptonite (usually the green or red variety) has been successfully produced by Lex Luthor, Batman, and Ra's al Ghul in the comics. It has proven to be less powerful than genuine kryptonite, to be extremely difficult to create, and to have a short half-life that renders it useless after a short period of time. In the Elseworlds story Batman: The Dark Knight Returns, Green Arrow wounds Superman with a synthetic kryptonite arrow, allowing Batman to defeat him. Bruce Wayne notes it was very expensive to develop, taking years to properly synthesize. Superman III featured synthetic kryptonite that altered Superman's personality.
  • Magic: Individuals adept at the use of magic may be able to create kryptonite, such as Mr. Mxyzptlk did in the "Krisis of the Krimson Kryptonite" storyline (though his version of Red Kryptonite differed from the traditional version in its workings, temporarily eliminating Superman's powers). Jimmy Olsen, when changed into a Genie in Superman's Pal, Jimmy Olsen #42 (January 1960), was ordered by his master, Abdul, to turn himself into Living Kryptonite, Jimmy chose Green Kryptonite.
  • On one occasion, Lex Luthor combined the element-duplicating substance that composes the robots known as the Metal Men into a single robot that imperfectly duplicated the properties of green kryptonite. While its presence caused Superman severe pain, it was not severe enough to completely incapacitate him, and did not affect his powers at all; thus, Superman was able to focus past the pain and defeat the robot.
  • Radiation: In the film Superman III, the computer Webster built was able to analyse Superman and find his weakness, and emitted a beam of radiation that simulates that of green kryptonite. It was stopped only when Gus Gorman pulled the plug.

Hoaxes

In the comics and other media, some varieties of kryptonite that turned out to be hoaxes:

  • Silver Kryptonite: Featured in Superman's Pal, Jimmy Olsen #70, Silver Kryptonite is a hoax revolving around the silver anniversary of Superman's career. Silver Kryptonite in another form is a part of the Smallville TV series (see Smallville below), but NOT of the comics continuity.
  • Yellow Kryptonite: This one was used in a hoax masterminded by Lex Luthor Action Comics #277.
  • Blood Kryptonite: In 52, the Cult of Conner - a religious sect dedicated to resurrecting Superboy, employed "Blood Kryptonite" in a preliminary ritual to resurrect Sue Dibny. While physically resembling Green Kryptonite, the "Blood" variant drains a portion of life force from present attendees, intended to direct this energy towards an effigy of the deceased as part of a Kryptonian resurrection ceremony. It is later revealed that this was a manipulation of Felix Faust and the rock was either regular green Kryptonite or not Kryptonite at all.
  • Kryptonite Plus: 30 or so non-glowing, varicolored, banded rocks invading unnamed Super-aliens had left on Earth's moon and then said were Kryptonite Plus or maybe a form of Ultra-Kryptonite. They are really Tikron Stones. From Superman's Pal, Jimmy Olsen #126 (January 1970).
  • Purple Spotted Kryptonite: Mentioned in Streaky's fictional story in the animated cartoon Krypto the Superdog. This phoney Kryptonite makes Krypto chase his tail.
  • Fake Kryptonite: Seen in an episode of Superboy 1988 TV series, Superboy's friends are selling crystals which are labeled as "fake Kryptonite" to raise money for charity. These crystals are clearly false and the vendors make no dispute about it. However, they use humorous references such as "Buy one and have nothing to fear; even Superboy will run away from you!"

Other media

As noted above, kryptonite was originally created for the 1940s Superman radio series. Kryptonite has appeared in various forms in the various Superman media spinoffs, however.


Depictions of kryptonite in the various films and TV series of Superman have largely been limited to green kryptonite, with occasional appearances of the red and blue varieties.


Adventures of Superman

Kryptonite was used in several episodes of Adventures of Superman, proceeding from straightforward to increasingly far-fetched plotlines. The specific color is not definite, given that it is never mentioned and that the series was in black & white, but from its effects, it is presumed to be green kryptonite in all cases: This article is about the television series. ... Black and White is a computer game developed by Lionhead Studios and published by Electronic Arts. ...

  • In "Panic in the Sky", Superman’s attempt to shift a meteor hurtling toward earth leaves him with amnesia. Although the scientists in the episode only say the meteor consist of "unknown elements", a fragment of this meteor is later used in The Deadly Rock, then referred to as Kryptonite.
  • In "The Defeat of Superman", an overacting scientist working for a crime boss synthesizes kryptonite after working out the formula from a tiny fragment found in a meteorite. As Superman lies dying from the metal's affects, Lois and Jimmy rescue him for once, sealing the block of kryptonite in a lead pipe, and Superman recovers. He then flings the pipe through the sky and into the sea with a super-throw. The escaping criminals, startled by the rocketing pipe, veer off the road and plummet to their deaths, keeping this dangerous secret "safe" in the hands of Superman's two friends.
  • In "Superman Week", Jimmy manages to blurt out the secret to the wrong listener. Superman stages an elaborate ruse in which he pretends to have retrieved the lead-encased metal from the ocean, and uses it to lead a wanted criminal into a trap. This ruse also presumably proves that Superman is not vulnerable to it, thus staving off criminals' thoughts of using it...for awhile.
  • In "The Deadly Rock", another eccentric scientist finds a meteorite that happens to be from Krypton, and a crime boss tries to use it to destroy Superman, who instead destroys it through the unlikely method of burning it with a flame-thrower.
  • In "The Magic Secret", yet another eccentric scientist teams with a criminal, this time tricking Superman into descending a narrow and deep well to rescue Lois and Jimmy, then proceeding to shower the Man of Steel with kryptonite particles.
  • In "The Gentle Monster", a very eccentric but good-natured scientist constructs a super-powered robot whose strength is derived from a chunk of the metal that the scientist has found, not knowing the danger it poses to Superman.

This article is about the metal. ...

Movies

Kryptonite was featured in Superman: The Movie. In the film, Lex Luthor (Gene Hackman) and his cronies (Ned Beatty and Valerie Perrine) 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 (Christopher Reeve) neck and drops him into a swimming pool. When Perrine's character Miss 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.

An imperfect synthesis of artificial kryptonite containing tar appeared in Superman III. Ross Webster (Robert Vaughn) orders the creation of synthetic kryptonite after remembering a Daily Planet story about the last original chunk disappearing years earlier after falling to Earth (whether Webster references the kryptonite robbery in Superman: The Movie is unclear.) Developed by Gus Gorman (played by Richard Pryor), it was intended to be a copy of Green Kryptonite. After scanning the coordinates of Krypton's former location via satellite, results return a small percentage of an unknown component. The substitution of tar (which Gorman used after glancing at a cigarette carton) for a crucial, but unknown, component resulted in the synthetic kryptonite behaving like Red Kryptonite and Black Kryptonite; in this case, the kryptonite turned Superman evil and eventually split him into two people. The evil Superman and Clark Kent, the embodiment of Superman's remaining good qualities, then engage in an epic battle at a deserted junkyard, where Clark emerges victorious and the evil Superman fades from sight. 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.

In Superman Returns, an additional piece of kryptonite is found in a rock fragment, once more in Addis Ababa. Lex Luthor steals it from a Metropolis museum and uses it in his quest to create a new kryptonite landmass, much like how young Clark created the Fortress of Solitude. In addition, he uses a shard leftover from processing it to create a kryptonite shiv, which he uses to stab Superman with at one point. Interestingly, Kryptonite is never once referred to as the term "meteor" as it is in the previous movies and Smallville series, only as "distant remains" or "radioactive pieces of [Superman's] home-world". This may have been an attempt on the writers' part to distinguish the Kryptonite of the movie away from Smallville, which is almost always referred to as "meteors". For the video game of the same name, see Superman Returns (video game). ... The Fortress of Solitude is the occasional headquarters of Superman in DC Comics. ...


The Adventures of Superboy

Kryptonite made frequent appearances in the syndicated "Superboy" TV series, most of it green. It first appeared in the first-season episode "Kryptonite Kills" in which Professor Peterson retrieved it from Addis Adaba believing it to be a harmless meteorite and brought it to his gemology class at Shuster University. Superboy, a student in Peterson's class (as Clark Kent), collapsed from the radiation and felt its effects for the first time. He later threw most of the Kryptonite into space, except for one piece which was washed into the sewer. That piece was discovered by a mixed-up scientist who used it as a power source for Metallo (Roger Corben) in the second season episode "Metallo". Superboy is a half-hour live-action television series based on the fictional DC Comics character Superboy. ... Metallo is a fictional supervillain and cyborg who appears in Superman stories published by DC Comics. ...


Green Kryptonite made several more appearances throughout the series, used mostly by Lex Luthor and Metallo. In the third season episode "Bride of Bizarro", Luthor sent Bizarro to a military research base to steal a large amount of Kryptonite, which Luthor was seen using on Superboy in later episodes. In the fourth season episode "Kryptonite Kid", a young man named Mike Walker working at the same military research base was caught in a Kryptonite explosion while working to find a cure which would make Superboy immune to the radiation. The Kryptonite entered his bloodstream and turned his skin green and he became "living, breathing Kryptonite" able to fire Kryptonite radiation from his hands. In "Obituary for a Super-Hero", Luthor used a Kryptonite bomb planted on a yacht to attempt to kill Superboy. The Kryptonite Man is the name of several supervillains who appears in stories published by DC Comics. ...


Red Kryptonite made an appearance in the second season episode "Super Menace". This version of Red K was created at a military research base where scientists were working to neutralize Kryptonite's effect on Superboy while still retaining its radioactive properties so it could be used as a power source. Their experiments turned the Kryptonite red, making it useless as a power source and altering its effect on Superboy. This Red Kryptonite turned Superboy evil, much like Red K would later do in the "Smallville" TV Series, except only a single exposure to it was required, rather than constant exposure. After Superboy wreaked havoc with Metallo, Lana tricked Superboy into being exposed to another chunk of Red Kryptonite which reversed the effects of the first. This is Red Kryptonite's only appearance in the series, so it is unknown if the substance would have had other effects on Superboy if it had appeared again.


The "Superboy" series also introduced a form of White Kryptonite, however this was not the white kryptonite that kills plant life (as seen in the Pre-Crisis comic books). This White K was created by Professor Peterson's duplicating ray in an attempt to create a form of Kryptonite that would kill the molecularly unstable Bizarro. This Kryptonite did not kill Bizarro, however. It instead had an opposite effect on him and actually stabilized and cured him, preventing him from eventually exploding as previous Bizarro duplicates had. White Kryptonite made only one appearance in the series in the episode "The Battle With Bizarro". It is referred to again in "The Bride of Bizarro" but it is not seen.


Lois and Clark: The New Adventures of Superman

Kryptonite was used throughout the 1990s television series Lois and Clark: The New Adventures of Superman. Lois and Clark: The New Adventures of Superman was a live-action television series based on the Superman comic books. ...

  • In "The Green, Green Glow of Home" the first piece was unearthed on the Smallville farm of Kent family friend Wayne Irig. He sent a sample of the rock to a local university. This came to the attention of Jason Trask. Trask headed Bureau 39, a secret government organization that investigated perceived alien threats. Trask had the paranoid belief that Superman was the first agent of an alien invasion. Understanding that the radioactive meteorite came from Krypton, he attempted to use the rock to kill Superman. Subsequently the main fragment of the meteorite was destroyed and Trask was killed by the local Sheriff. Consequently only Clark Kent and his parents knew of its true existence. Clark and his partner Lois Lane reported on the incident in The Daily Planet and described Trask's delusions of a fabled rock that could kill Superman. Ironically in this article it was Clark Kent himself who first named it "Kryptonite".
  • As shown in "Barbarians at the Planet" and "The House of Luthor" The story of kryptonite intrigued Superman's archenemy Lex Luthor. He used the many resources at his disposal to track down and confirm the existence of the original sample that Irig had sent to be studied. Luthor ground down part of this kryptonite and used it to coat the bars of a cage to entrap the Man of Steel. After Superman's escape from this kryptonite prison and Luthor's apparent death, the legend of kryptonite continued to grow.
  • Many criminals and former Lexcorp employees sought to acquire Luthor's kryptonite. In fact most of the kryptonite to be featured on the series originated from that first chunk found by Wayne Irig. During the 3rd season a new second piece was discovered, which Superman turned over to S.T.A.R. Labs for testing. This was the source of most of the kryptonite featured for the remainder of the series.
  • On Lois and Clark, green kryptonite was delivered in a variety of ingenious ways. A bullet was fashioned from pure kryptonite in one episode, and in another, a wicked woman tried to bring about Superman's demise by kissing him after coating her lips with a kryptonite-contaminated lipstick. In the episode "Metallo", scientist Emmett Vale, who studied Luthor's kryptonite while working at Lexlabs, used a piece to power the cyborg he created from fatally wounded criminal John Corben.
  • Red Kryptonite also was featured in the series. In one episode, it made Superman apathetic; in another, it transferred his powers to Lois Lane after being focused through a laser beam. In yet another, it uncontrollably supercharged his powers, causing him to do things such as accidentally fly through the sidewalk when landing. A renegade S.T.A.R. Labs scientist created a "Hybrid Kryptonite," which has no effect on Kryptonians, but hurts humans.

Animated series

The 1970s and 1980s Super Friends animated series featured kryptonite in various episodes, usually green. In the episode "Rest in Peace", Sinestro refers to a form of kryptonite called "Krypton Steel" as "a harmless form of kryptonite that only Superman can penetrate". In another episode, "Darkseid's Golden Trap", gold kryptonite appears, which is stated to have an effective range of 20 ft (6.1 m). Blue kryptonite also makes an appearance in an episode entitled "Terror From the Phantom Zone"; Superman, aging rapidly from exposure to Red Kryptonite, acquires a sample of Blue Kryptonite (which had been discovered floating in space) and uses it to cure himself (Blue Kryptonite has negative effects on Bizzaro, so it should have positive effects on Superman). In "Uncle Mxyzptlk", the Wonder Twins find a red, glowing stone and take it to the Hall of Justice. They show it to Superman...who immediately reacts to it. Samurai knocks the red kryptonite to the floor but the affects of the red kryptonite cause Superman to decrease in age...becoming a kid of maybe 5 or 6 years old. The rest of the Superfriends refer to the kid as 'Super Brat'. In another episode, red kryptonite is exposed to Superman by Bizarro himself...causing Superman to transform into a gangly, weak klutz. In yet another episode of Superfriends, red kryptonite causes Superman to grow additional arms and legs...most of the action takes place at the Fortress of Solitude where Superman finds some blue kryptonite hidden away to fight off Bizarro.

In the 1990s series, Superman: The Animated Series, one explanation offered for the science of kryptonite is that Superman feels the detrimental effects of kryptonite radiation quicker that normal humans because his body absorbs it more readily, as a result of sharing a common point of origin with the element. The effect is so potent that even a tiny shard is enough to painfully affect Superman at a short distance. This makes it impossible for Superman to even touch the substance, as it would be the equivalent of a normal man touching radioactive rods from a nuclear reactor with his bare skin. Only the element of lead is able to block the radiation, and is therefore Superman's only protection. Fortunately, Professor Hamilton supplies Superman with a distinctive and durable lead protection suit for such situations.

Kryptonite, in the animated series, still has effects on normal humans as well. Two moments are evidence of this. First, the "Jade Dragon" from The Batman/Superman Movie (a crossover between The New Batman Adventures and Superman: The Animated Series) is a statue of kryptonite carved in the form of a Chinese dragon, said to be cursed because all of its owners all died within a few years of acquiring the piece. Second is Lex Luthor's kryptonite poisoning/cancer as seen in Justice League, attributed to Lex's admitted habit of keeping a fist-sized chunk of kryptonite in his pocket for years. This does bring up the question of Batman's habit of also carrying a piece of kryptonite in his own belt; however, since Batman has seen what the kryptonite did to Luthor, the famed methodicality of Batman may mean that he likely has the pouch lined with lead. In Batman Beyond, it was revealed in the two part episode "The Call" that Bruce Wayne kept the kryptonite for the rest of his life, and kept the needle of kryptonite locked up very securely in the Bat Cave. The Justice League series also reveals how Batman obtained the kryptonite. Worlds Finest is a three part episode of both Superman: The Animated Series and The New Batman/Superman Adventures. ...

Green kryptonite remains the only variety of the substance ever seen in the DCAU. The DCAU or DC Animated Universe is a general term made by fans of the animated television series based off of DC Comics, usually heavily developed by Bruce Timm and Paul Dini. ...


As mentioned above, the Krypto the Superdog episode "Streaky's Cat Tail" features "purple-spotted kryptonite", which causes Superdog to compulsively chase his tail. However, this was almost certainly a product of Streaky's imagination. Red Kryptonite has appeared and is stated as having weird effects on Kryptonians for a day; it has swapped the minds of Kevin and Krypto, removed Krypto's powers. and in episode caused Krypto's tail to become sentient and separated from his body. Kryptonite also appears in an episode of the Legion of Super Heroes cartoon, where it is revealed Brainiac 5 has a piece of it, and that the villain Drax, who, despite being an analogue to Superman, is immune to it.

Smallville

In the 2000s television series Smallville, the show expands on the concept of the substance being harmful to humans, as well as making extensive use of the substance. On the show, not only is green kryptonite (referred to in the first two seasons of the series as "meteor rock") harmful to Clark Kent, but it can produce bizarre changes in humans, animals, and plants, typically turning them into powerful mutant menaces, commonly known by the inhabitants of Smallville as "Meteor Freaks," that Clark must oppose. These changes seem to be linked to the circumstances under which the subject was exposed to kryptonite and the subject's emotional state (similar to how gamma radiation affects people in the Marvel Comics universe). Groups of people have been shown to acquire the same powers from kryptonite by exposing themselves to it in the same manner. Kryptonite is a fictional element originating from a meteor shower composed of the radioactive remains of the planet Krypton. ... Smallville is an American television series created by writer/producers Alfred Gough and Miles Millar, and was initially broadcast by The WB. After its fifth season, the WB and UPN merged to form The CW, which is the current broadcaster for the show in the United States. ... For other uses, see Clark Kent (disambiguation). ... The idea of a mutant is a common trope in comic books and science fiction. ... This article is about electromagnetic radiation. ...

The harm inflicted on Clark by kryptonite on Smallville is varied. He cannot be near green kryptonite without doubling over in nausea and pain, and if he were to hold a fragment of it in his hand, it would burn to the touch and the veins in his hand would become exposed and green. However, on other separate occasions Clark has held and even ingested kryptonite (albeit in dilluted form) and been merely weakened. When a vial of Clark's blood was held up to kryptonite to verify its authenticity, the blood began to boil.


Red kryptonite has also been shown in Smallville. Its effect on Clark Kent is to rid him of all inhibitions, making him rebellious and potentially dangerous if exposed to it for too long. Also created for the series was black kryptonite (first appearing in the episode "Crusade"), which is capable of separating certain entities within individual organisms, e.g., splitting a person's good and evil sides.


Black kryptonite was formed by heating up green kryptonite. In the series, after Clark's "reprogramming" by Jor-El in the caves, Martha Kent used black kryptonite to reveal the two psyches of Clark, the militant Kal-El (not to be confused with the rebellious "Kal" alias caused by red kryptonite), and normal Clark. In a later episode, Lex Luthor was experimenting with a process to heat up green kryptonite and irradiate seeds, in order to separate the "weak" genes from the "strong" genes in the seeds. The result was hardy but rotten-tasting fruit, implying a yin and yang balance within fruit, as well as within humans. An accident with this process caused Lex to split into a good Lex and a bad Lex who referred to himself as "Alexander". Japanese name Kanji: Hiragana: Vietnamese name Vietnamese: In Chinese philosophy the yin and yang (simplified Chinese: ; traditional Chinese: ; pinyin: ) are generalized descriptions of the antitheses or mutual correlations in human perceptions of phenomena in the natural world, combining to create a unity of opposites in the theory of the Taiji. ...


Silver kryptonite made an appearance in the fifth season episode entitled "Splinter'. Like the previous comics incarnation, this silver form was not a true form of the stone. In the episode, Clark pricked his finger on a rock that was black and had silver-metallic clusters, and subsequently became increasingly paranoid, hallucinating that others were conspiring against him. In the episode's final scenes, it was revealed that a splinter of the element entered Clark's bloodstream. It was also shown that silver kryptonite was created artificially from the liquid metal which forms Brainiac's body. A hallucination is a perception in the absence of a stimulus that the person may or may not believe is real. ... Brainiac is a fictional character, a DC Comics supervillain and frequent opponent of Superman. ...


In the eighth episode of Smallville's 7th Season, entitled "Blue," there was a new form of Kryptonite. It was blue kryptonite, for obvious reasons, and it stripped Clark of his powers. This happened when Lara Lor-Van, Clark's mother, gave Clark his father's blue ring to wear, without knowing the affect it would have on him. The ring was impossible to remove until Clark returned to The Fortress of Solitude. Lara Lor-Van, usually referred to as Lara, is a fictional character who appears in Superman comics published by DC Comics. ... The Fortress of Solitude is a 2003 Jonathan Lethem novel set in Brooklyn, spanning the 1970s, 80s, and 90s. ...
