DEATH BY KRYPTONITE
Although it is often cited as being deadly, are there any canonical examples of Kryptonians dying by Kryptonite exposure? —Preceding unsigned comment added by 66.109.248.114 (talk)

Good question. But, didn't the entire city of Argon, Supergirl's home, die from kryptonite radiation when meteorites pierced their protective shielding? That was the reason they sent Kara Zor-El to Earth; at least that is what I thought. Bignole 02:32, 2 November 2006 (UTC)


 * In mordern continuity millions of Kryptonians died of kryptonite exposure before the planet finally exploded (World of Krypton mini-series) and Superman used green kryptonite to execute a trio of Phantom Zone criminals from a parallel universe he was visting (Supergirl Saga). Beyond them, the most famous, but non-canonical example would be Superman himself in Jerry Siegel's original Death of Superman imaginary tale. --Jason Kirk 11:05, 2 November 2006 (UTC)

I have several stories where various artificial Super-powered Kryptonians were ended by Green K exposure. A Superboy story has a Kryptonian turned into an Ape truned back and slain by Green K as a man. All of the inhabitants of Argo City did die of anti-kryptonite, which only effects non-super-powered Kryptonians, which must have been the case of the few who died on Krypton just before the big bang, No Bizarro died of Blue K exposure but that was just because they were never living in the first place. —Preceding unsigned comment added by 75.40.109.112 (talk) 05:09, 26 January 2009 (UTC)
 * A Bizarro-Supergirl did "die" from blue K exposure in Superman #140, the same issue that introduced blue K. WaxTadpole (talk) 18:51, 1 April 2021 (UTC)

Element?
Why is Kryptonite described as an "element" when it is later suggested that it is actually a compound or a mixture ("Sodium lithium boron silicate hydroxide with fluorine")? &mdash; Paul G 08:32, 24 April 2007 (UTC)
 * I assume it's because over 50 years of comic book stories have identified it as an element, as opposed to one movie that said it was a compound. Since Superman originated in comic books, it makes sense to give them priority. WaxTadpole (talk) 22:17, 12 August 2011 (UTC)
 * Actual Action Comics #591 expressly states that the Kryptonite of the Pocket Universe "contain all the elements as Kryptonite the radiation they produce is completely different from the stuff I know." (sic)--2606:A000:7D44:100:A5AB:92A:58C3:C3D8 (talk) 01:19, 3 December 2016 (UTC)

Lable in Superman Returns
In the movie Superman Returns, isn't a different chemical structure listed for the kryptonite displayed? I remember it saying things like silicone or something on the lable. Yami (talk) 16:54, 20 May 2009 (UTC)


 * according to IMDB the chemical name for kyrptonite is sodium lithium boron silicate hydroxide with fluorine Yami (talk) 17:05, 20 May 2009 (UTC)

kryptonite not Kryptonite
I have gone through the article (manually!) to remove the unnecessary capitalizations. Elements and molecules are not capitalized, except when starting a sentence, etc. Likewise, green doesn't need to be capitalized just because it is describing kryptonite. I may have missed a few instances (as I said, I very slowly read this sprawling article in edit mode), but let's try to keep things consistent. Matt Deres (talk) 02:41, 11 July 2009 (UTC)


 * Just wondering what the consensus is about capitalisation of kryptonite. The article still has lots of capitalisation. I agree with you, that it should not be capitalised. e.g., look at the wiki page on gold. dictionary.com and Max OS X dictionary all use a little 'k'. This has also been brought up under Other varieties and Length Ferion69 (talk) 01:25, 28 July 2013 (UTC)

Pink kryptonite
The wording "caused that universe's Superman act in a manner similar to stereotypes of homosexual men in the 1950s and '60s." seems POV. What is the source for this opinion? Wperdue (talk) 19:28, 15 October 2009 (UTC)


 * I'd say "the story", since it's absolutely clear that that's what's intended (he even uses the word "fabulous"). But I get that, since there isn't an explicit statement, it's not encyclopedic. The current version of the page, which just describes Superman's behaviour and leaves the reader to draw the conclusion themselves, is probably better. 92.21.250.153 (talk) 20:10, 17 April 2010 (UTC)
 * Seriously... this article goes to extreme lengths in dancing around the fact that PINK KRYPTONITE MAKES SUPERMAN GAY. Just say it!!! MultipleTom (talk) 16:14, 17 June 2011 (UTC)

Silver Kryptonite
Someone with any patience might want to edit the table to add in silver Kryptonite as a actual element. Smallville season five, episode seven, he gets a splinter of the stuff and it turns him into a paranoid freak. It also affects Lana Lang. —Preceding unsigned comment added by 98.207.255.223 (talk) 20:40, 20 November 2009 (UTC) Nah, silver "kryptonite" isn't actually kryptonite. thus, it doesn't belong in the table.--Marhawkman (talk) 20:47, 20 November 2009 (UTC)

Color / Effect

Gemstone kryptonite
"Jewel kryptonite" in the comics enhances the psychic powers of Kryptonians. "Gemstone kryptonite" in Smallville gives Clark mind-control powers. Are these two continuities' versions of the same substance? 92.21.250.153 (talk) 20:07, 17 April 2010 (UTC)
 * Dunno. Might want to look for a citation - something in writing and not an observation of the show or reading of the comics that describes and compares them. Jack Sebastian (talk) 05:13, 18 April 2010 (UTC)

Jason Siegle
Not trying to be a smart alec, but the article refers to Jason Siegle at least twice. Is this the error it seems to be? — Preceding unsigned comment added by Captrose (talk • contribs) 21:08, 24 January 2011 (UTC)

When was kryptonite introduced to the storylines?
I've just reverted an anonymous user's addition of an uncited statement that it first was used in the tv series. Lois and Clark. I know that as patently inaccurate, but do not know when it was first introduced. I've found through a number of suspect sources that it was in the radio shows of the 1940's, but a better citation is needed. The most likely (but again, unreliably sourced) likely introduction in the comics would be Superman #61, after the aforementioned appearance in 19431 I don't see how we can include anything about the first appearance without reliable, verifiable citation. Thoughts, anyone? - Jack Sebastian (talk) 18:46, 18 February 2012 (UTC)


 * Here's an episode of the radio show that introduced it: oldtimeradiodownloads .com/ adventure/superman-the-adventures-of/the-meteor-from-krypton-ep03of07-1943-06-07
 * As of 2023, the wiki article states Superman was not exposed to it, but listen to the episode. WimbledonGreen (talk) 18:18, 23 October 2023 (UTC)

Empty Nest
In the TV show, Empty Nest, the pedriatician who is the show's protagonist suggests using kryptonite to treat a young boy who is in costume as Spider-Man. The boy protests that kryptonite is part of the Superman universe, not Spider-Man's. However, the good doctor is right. Since Spider-Man is an earth-human (and one who got his powers from radioactivity, according to some versions), kryptonite would definitely enhance his powers.

White kryptonite and Superman 3
Im not sure who wrote the entry on this but im pretty sure they were wrong about the color in the movie, as the compound that Richard Pryors character produces tuned out to be a dull red color, not white. Perhaps this was meant to give a new origin to red kryptonite for possible movie sequels, but it was in no way white. 65.74.45.157 (talk) 02:39, 2 April 2012 (UTC)

Nonsensical
"Jerry Siegel also stated that the naming of the planet Krypton was taken from the element Krypton due to the common denominators of high density and viscosity between the two." I doubt this is actually what he said. It makes no sense due to the fact that he invented the planet Krypton. How can he take the naming of the planet from the element due to the "common denominators" when, in fact, his creation doesn't exist? — Preceding unsigned comment added by 71.84.167.16 (talk) 06:55, 31 May 2013 (UTC)
 * I have no published source for this, but I heard it from veteran DC editor Julius Schwartz when he spoke at a convention. He said that Jerry Siegel once told him that one of his inspirations for Superman was the John Carter stories of Edgar Rice Burroughs. John Carter was an Earthman on Mars who had great strength and could leap long distances because of the lesser gravity. Since the capital city of Mars was called Helium, Siegel named Superman's home planet after a different noble gas, Krypton, as a nod to ENB fans. WaxTadpole (talk) 18:40, 1 April 2021 (UTC)

Red Kryptonite -Smallville
Under "Forms of Kryptonite -> Variations -> Red Kryptonite" I'd like to change the end of the 5th paragraph and add a reference:

currently: "Smallville red Kryptonite requires close contact with skin to be effective, such as being worn in a ring or necklace."

change to something like: "Smallville red Kyrptonite requires close proximity to the skin to be effectives, such as being worn in a ring, necklace or in a shirt pocket. ,"

The change removes the word "contact", as it appears that contact with the skin is not necessary for the red Kryptonite to have an effect on Clark. See Rush around 26min 21s. Here Pete puts the Red-K into Clark's shirt pocket and it has an effect on Clark. What do people think? Thanks, Ferion69 (talk) 00:43, 28 July 2013 (UTC)


 * I'm having some difficulty taking seriously this discussion about each and every form that kryptonite takes in a single tv series, even one as long-running as Smallville. And I should point out that citing different episodes and then drawing conclusions/inferences/implications from the viewing of those episodes, without a single shred of reliable sourcing from a notable reference commenting about any of this is going to attract a lot of deletionist attention. I'm going to wait about a week, giving the main contributors to this series to come up with some sourcing that isn't directly lifted from the series (and therefore OR) before starting a fairly large trimming. It cannot remain in its current form. - Jack Sebastian (talk) 04:33, 29 July 2013 (UTC)
 * Further to this, a great deal of the article is very fannish and speculative in its style. I have to agree with the info boxes. I'm going to tidy this up section by section so that it reads like an out of universe article (as it should) as opposed to appearing like it was written by and for DC fans. It would be nice to be able to eventually nominate this article for Featured status, but we are a long way off right now. A review in perhaps a month would be nice. Asgardian (talk) 09:29, 6 July 2014 (UTC)
 * Making a start. Other Media straight-forward, although all Music examples will need to be sourced. Asgardian (talk) 10:06, 6 July 2014 (UTC)

New 52
Should the different origins and qualities for the Post-Crisis and Post-Flashpoint versions be explicated? There is, in fact, no mention of the post-Flashpoint versions (Green, Red, Blue, Violet) of the mineral at all. — Preceding unsigned comment added by 62.163.78.104 (talk) 11:30, 27 January 2015 (UTC)

Forming black kryptonite
Quote: "black, formed when superheating green kryptonite." When a green kryptonite meteor comes through the Earth's atmosphere, friction hot enough to melt metal and stone (surface only as stone is a poor conductor of heat) would turn all green kryptonite to black kryptonite.(80.31.144.16 (talk) 19:17, 27 October 2015 (UTC))

Ant Kryptonite
I recall a sidebar in a 60s or early 70s comic that identified several types of Kryptonite, including one that turned Superman into an ant-like being.

It didn't identify a previous story that used it but it did assert that such a kryptonite existed.--23.119.204.117 (talk) 01:04, 3 April 2016 (UTC)


 * I think red kryptonite once gave Superboy an ant head. (See my question below.) —Tamfang (talk) 00:43, 17 August 2019 (UTC)

Dark Blue kryptonite?
In Superboy #23 (Dec 52-Jan 53), a dark blue rock which must surely be kryptonite to affect Superboy, makes him a hundred times as strong as normal and even invulnerable to the weakening affects of green kryptonite. (5.8.188.52 (talk) 06:35, 4 October 2016 (UTC))

Collyer taking breaks
From Flights of Fantasy: The Unauthorized but True Story of Radio & TV's Adventures of Superman by Michael J. Hayde:

""One of the most persistent Superman legends is that kryptonite was created so Bud Collyer could take a vacation. Presumably the Man of Steel would remain exposed to the deadly element for several days, and any male voice could moan and groan while other characters carried the story. That may have turned out to be a fringe benefit much later, but this introductory arc lasted only 7 days and Collyer was present for all of them. [...] Since Superman's life isn't threatened - the meteorite never leaves the doctor's custody - it's likely that Lowther's primary intent was to create the means for Superman to discover his own origin.""

Christ, I'm sick of how often this myth keeps turning up on r/todayilearned.Kurzon (talk) 16:28, 15 July 2018 (UTC)


 * I don’t have a source for this but in a later arc Collyer is in fact absent for several shows after the villains bury Superman alive with kryptonite. Batman and Robin take over the lead roles in these episodes. These shows also establish that radio kryptonte doesn’t actually kill Superman, only incapacitates him — the villains must resort to attempting to starve him to death because he retains his invulnerability. — Preceding unsigned comment added by VisualPal (talk • contribs) 22:19, 16 August 2019 (UTC)

red uniqueness
Do I remember right that (in the Silver Age) each piece of red kryptonite affected Superboy differently and only once, so that he could harmlessly keep any piece that had already done its thing? —Tamfang (talk) 01:16, 6 September 2018 (UTC)

X-kryptonite harmful to Kryptonians?
The section on X-kryptonite says "Harmless to Kryptonians, the mineral gives normal lifeforms superhuman abilities, as in the case of Supergirl's pet, Streaky the Supercat. Revised in Superman Family #203 (Oct. 1980) to have the same effect as the green variety on Kryptonians." I'd like to see a citation for the first part of this. In Action Comics #261, Supergirl accidentally created X-kryptonite while attempting to find a chemical that would neutralize kryptonite radiation. She declared her experiment a failure and disposed of the rock, not realizing that she had transformed it. If X-kryptonite was harmless to her, she would not have considered the experiment a failure.
