The table showing all the different types of kryptonite and their effects is not showing up! —Preceding unsigned comment added by (talk) 08:49, 28 January 2008 (UTC)

More info about animated series[edit]

This page needs more info about the 90's Superman: The Animated Series. It seems way to heavily geared towards the live action movie versions of Superman. Alph

3 Doors Down[edit]

I added some 3 Door's down info (mainly just a link) since they did a song called Kryptonite. Zikar


Whose "theories" are these about Kryptonite being in the island of stability, the krypton nucleon, etc.? Were they introduced in the Superman comic book, or are they simply the inventions of a fan (and/or the author of this Wiki article)? If the former, please mention the issues in which these concepts were introduced. If the latter, I really think it has no place on Wikipedia, and should be removed.

I have no idea, I was working from secondary material that didn't attribute anything. I don't read the comic myself. I do remember hearing the "island of stability" theory on the TV show "Lois and Clark", however; I believe Kryptonite was given atomic number 126 in that show. -BD
Fictional chemical substance confirms that number, so I added the info to Unbihexium... However, now I realized this article says it's in the vicinity of atomic number 150. 126 isn't mentioned at all in this article. 126 is also in the island of stability, however... --Spug 17:45, 2 Feb 2005 (UTC)

Also, I believe that the different variaties of kryptonite were eliminated in the post-Crisis DC universe. There is only green kryptonite, and the red isotope discovered by Batman in last year's JLA storyline. Can someone verify this? If it is true, it should be mentioned in the article as well.

-- CYD

Needs confirmation[edit]

moved here from main article until confirmation can be found:

Another theory proposes that Kryptonite is actually an ordinary element that contains an unusual type of nucleon in addition to the usual protons and neutrons present in atomic nuclei. This hypothetical nucleon has been dubbed the krypton (lowercase, to distinguish it from the planet of the same name); atoms that contain them are said to have been kryptonized, and highly kryptonized atoms (such as those of Kryptonite) may be unstable and emit krypton particle radiation. The exact properties of kryptons and kryptonized atoms have not been studied in any sort of rigorous detail, but it is speculated that low levels of kryptonization in their tissues may be directly responsible for the unusual properties exhibited by Kryptonian natives in krypton-poor environments such as Earth. Krypton theory can account for many of the effects that different versions of Kryptonite have; for example, gold Kryptonite may contain high levels of antikryptons that dekryptonize any Kryptonians that are exposed to its antikrypton radiaton.

Under this theory, the transmutation of Earth's Kryptonite to iron may be explained by Kryptonite being kryptonized iron which returned to the form of ordinary iron when the kryptons were removed.


I once wrote a song about Kryptonite, the theory being that just as Superman was made weak by his home planet, so were we, and if we could just live on some other planet, we would have superpowers too.

The whole damn world's made of kryptonite,
Robbing us all of our X-ray sight.


Other varieties[edit]

Hey. Added information about Magno-Kryptonite and Bizarro Red K on 1/15/05, and altered the capitalization of "kryptonite" to conform with DC's (Pre-Crisis) style as defined by editor E. Nelson Bridwell. --MWaid

Cartoon series?[edit]

I belive the Superfriends or origional Justice League (pre-Cartoon Network) had an episode, which gave Superman double or more the ammount of limbs (both arms and legs), and involved a form of Kryptonite. : STrRedWolf

Pink Kryptonite?[edit]

Supergirl v5 issue 2 ends with Lex Luthor making an inventory of the post-Crisis Kryptonite in his posession: Green (natural, but he refers to synthetic too), Red, Blue, and Black. I'm willing to assume that the rainbow of inert Kryptonite found in the Pocket Universe is irrelevant, as is the stuff that Ultraman from (Grant Morrison's) Earth-2/Antimatter Dimension calls Kryptonite. -- Mozai

Is it appropriate to mention "Pink Kryptonite?" At first glance it seems like an ingredient of slash fiction, but I found mention of it in regards to Supergirl v4 issue 79. However, all of the comments made were "hilarious," "great joke," and "tip of the hat."

The writer of issue #79, Peter David, had in that issue a visit to a pre-Crisis-like alternate Earth (accessed via Hypertime IIRC), where Pink-K is revealed to exist. Thus, figure the entry on the page (complete with note about it being from an alternate Earth) should be fine.
Also, if you want to sign your name, you can put "~~~~" (four tildes) at the end of your message. Anthony Dean 15:10, 2 October 2005 (UTC)
I had to look that up to be sure, but it's indeed there. Page 13, top panel (and only there). The context is as follows: Supergirl III (Linda Danvers of post-Crisis Earth) trades places with Supergirl I (Kara Zor-El from pre-Crisis Earth 2; read the comics to know the mechanics behind all this, which are as usual far too complicated to explain in one sentence). Of course, things were a little different in the old days, which is gently poked fun at. Scene: the Daily Planet. Caption: "Granted, every so often there's some genuine weirdness. Fortunately, I'm the only one who seems to pick up on the context." Lois: "You know, Superman's been acting awfully strange since being exposed to pink kryptonite. What do you think's wrong with him?" Linda: "Lois, you so don't want to know". Superman talking to Jimmy Olsen on the right: "Did I ever tell you how smashing you look in bowties, Jimmy? By the way, that's a fabulous window treatment you've put together." Jimmy: "*gulp* Gee... thanks, I guess."
This pokes fun at both the "innocent times" and the myriad hues of kryptonite that fueled the old stories. I've updated the article to reflect that it was a one-shot joke (the previous version read as if pink K could be introduced in mainstream continuity any moment now, which is unlikely to say the least). 19:55, 2 October 2005 (UTC)


I don't quite understand how the synthesized kryptonite from "Superman III" is anything like Red Kryptonite. It has the effect of Black Kryptonite, in my opinion, splitting Superman into two. I could be wrong. RandallFlagg 00:20, 11 November 2005 (UTC)

Well for one thing there was no "Black Kryptonite" back when the movie was made. That is an invention of Smallville. Red Kryptonite originally had a different effect on Superman each new time he was exposed to it. One of the effects was being split into two. One good and one bad. "Black Kryptonite" is redundant. Avilos 27 January 2006 (UTC)
The Kryptonite in Superman III was created when Richard Prior's character substituted tar for the unknown constituent. Maybe it can be called "Tar Kryptonite." Also, it did not create an "evil Superman." It let him act upon selfish desires, just like the Red Kryptonite in Smallville. (talk) 22:14, 2 June 2008 (UTC)

In the section on Superman 1, someone has written that "kryptonite seems to mean simply a kryptonian meteorite." I don't understand the meaning of this comment. What else is "kryptonite" supposed to mean, and how does the movie fail to satisfy this meaning? Chalkieperfect 03:51, 18 February 2007 (UTC)

In World's Finest 100 Lex Luthor invaded the bottle city of Kandor both shrinking himself and boring through the "cork." He greeted the visitor-starved Kandorians with, "Kryptonites!" That would make the earliest form of Kryptonite, the Kryptonians themselves and the most common color flesh. All Kryptonian-based Bizarros would thus be artificial Kryptonites.

The Animated Series[edit]

The pocket of Batman's utility belt that holds his kryptonite would most definitely have to be lead-lined, not only for his safety but that of Superman. Otherwise Superman would always be affected by the kryptonite in Batman's presence. RandallFlagg 00:38, 11 November 2005 (UTC)

That may make logical sense, but it still constitutes original research, unless it is specifically mentioned in the show (or perhaps in supplementary features or something). (talk) 18:46, 8 April 2009 (UTC)


My interpretation of Silver Kryptonite as seen in the episode "Splinter" is that Silver Kryptonite is indeed a hoax. It was actually a part of Braniac imbedded in a rock, meant to be passed off as a new type of meteor rock. A piece of Brainiac then entered Clark's bloodstream when he cut his finger on it, causing the delusions. How it caused delusions is unclear, perhaps it was a sort of bio-software that rewired Clark's brain. RandallFlagg 02:10, 11 November 2005 (UTC)

Speaking of Silver Kryptonite, I've reverted the page several times within the past day or so already---information on the "Smallville" version of Silver-K belongs in, and is already listed in, the "Smallville" section, not the "Comics" section's entry on Silver-K (which is something else entirely). Anthony Dean 03:19, 12 November 2005 (UTC)

Just a comment on the Smallville section[edit]

It is interesting to note that exposure to kryptonite among whites causes them to gain superpowers while prolonged exposure to blacks causes them to have involuntary spasms and seizures (as evidenced in the episodes "Jitters" and "Duplicity").

Am I the only one who finds this comment bigoted or prejudiced especially in light of more recent episodes?

Bigoted or not, this doesn't have any business in the article unless the series itself has ever made this point. There's no call for "speculation" about something that could be empirically confirmed or rejected just by consulting the series' staff. Chalkieperfect 03:37, 18 February 2007 (UTC)

Size of Krypton/ Essene New Testament?[edit]

The "Size of Krypton" section currently has passage referring to "determinations of the mean distance between Krypton and Earth derived from certain passages in the Essene New Testament." What possible relevance could the "Essene New Testament" (whatever that might mean in this context) have to the distance between Krypton and Earth? (There are various works of dubious authenticity which use the title or subtitle "Essene New Testament", usually to claim a connection with the Essenes and the Dead Sea Scrolls, but none of them have any relevance to Superman, as far as I know.)

This absurdity seems to have been added by an anonymous editor way back in 2003. I find it hard to credit that such a bit of patent nonsense could have lasted so long on an article with so many contributors. Now, I don't know much about astronomy, so I can't speak to whether the rest of that section is as silly as the "Essene New Testament" reference. But my inclination would be to remove the entire section, or move it to WP:BJAODN. I won't do that until other editors have a chance to comment, but I will remove the Essene New Testament business. —Josiah Rowe (talkcontribs) 04:52, 14 November 2005 (UTC)

Hmm...I was tempted to remove the "Essene" bit earlier, but I didn't know whether it was some religious material or an actual (obscure even for *me*) comic reference (not having heard of it before), so left it alone for someone else to delete. That, and being too busy trying to deal with the "Smallville" material being added to the comics-related material... Anyway, if there's an actual reference to Krypton's size from somewhere else, I'd cite that, but otherwise, guess the section can be removed. Anthony Dean 13:39, 14 November 2005 (UTC)
There is a nugget of sense in the section: that since Krypton was many, many light-years away from Earth (possibly even in another galaxy), it's pretty silly to assume that, after it exploded, large quantities of matter from the planet would end up here. There probably is even an argument to be made for saying "the only way this much Kryptonite could have ended up on Earth is if the planet was bloody huge, so big in fact that it would have collapsed under its own weight." But I doubt that the 107 figure can be supported, and the "several sources" mentioned in the paragraph should either be named or deleted. —Josiah Rowe (talkcontribs) 16:25, 14 November 2005 (UTC)
Okay, did a little research and a little creative math to come up with a size for Krypton. According to "Superman: The Ultimate Guide to the Man of Steel", Krypton orbited a Red Dwarf star (as a a side note, it is stated Krypton was located only 50 light years from Earth, making it impossible for Krypton to have been located in another galaxy). According to Wikipedia, Red Dwarf stars are supposed to be less than one third the size of our own sun, which measures 1,400,000km or 868,000 miles in diameter. Giving Rao (the Kryptonian sun) the benefit of the doubt, I made it exactly one third the size of our sun,466,666km or 289333 miles in diameter. Then based on a diagram of the Krytonian solar system in said guidebook, I was able to extrapolate the size of Krypton as compared to Rao and arrived at a diameter of 58,333km or 36,166 miles as compared to the Earth's 12,756km or 7909 miles. I know that's not an entirely seemless method. But, I do believe it merits review.RandallFlagg 02:24, 15 November 2005 (UTC)
Hmm... while I admire your ingenuity, I'm not sure that we should base an entry in an encyclopedia on a calculation based on an illustration in a tie-in book. (Is the diagram even necessarily to scale? I know that diagrams of our own solar system often are not.) That said, the 50-light-year distance is interesting (I notice it's mentioned at Krypton (planet) as well), and might be the seed of something more solid here. —Josiah Rowe (talkcontribs) 04:12, 15 November 2005 (UTC)

Fans noticed that a ridiculously large amount of Kryptonite fell on Earth in all those old stories.

Someone said "Hey, I bet it'd be amusing to calculate how big the planet would be to send us that much Kryptonite."

Of course they calculated a really big number. It's like watching Indiana Jones hold onto a falling bridge and slam into a cliff, then calculating that his muscles would have to be stronger than steel for him to hold on. The calculation is technically correct, but the point isn't that Indiana Jones' muscles are stronger than steel--it's just a roundabout way of saying that what we see doesn't make a lot of sense.

Which in turn is the point of the anisotropic reference and the kryptonite being towed by the rocket--if you don't assume the distribution is anisotropic and make up some explanation as to why it isn't, the whole thing makes more sense and you don't calculate an impossibly huge planet.

I've modified the paragraph myself. The "anisotropic", "107", and black hole are gone. Ken Arromdee 05:51, 15 November 2005 (UTC)

Thanks, Ken. It's much more sensible now. —Josiah Rowe (talkcontribs) 06:14, 15 November 2005 (UTC)
Edited it again. The space warp was mentioned in an earlier section, so the entire paragraph was redundant.
Also, removed speculation about Infinite Crisis. Ken Arromdee 00:16, 16 November 2005 (UTC)

Color links[edit]

I am going to take out the color links in front of the various Kryptonites’ if people really want to see the colors they can look them up. We do not need links for all of the colors as well. Whispering 21:22, 16 November 2005 (UTC) disambiguation link repair (You can help!)

Now this, I agree with. (^_^)Gzuckier 04:20, 17 November 2005 (UTC)
Just a little more editing I think I'm going to go take out the rest of the color links as well. Maybe any other useless links, someone can always put them back in if their judged useful later. Whispering 19:35, 17 November 2005 (UTC)
Oh I wish you wouldn't. I found it the section on colors most interesting. It's the first time I've ever seen them all gathered together. Why should we make people interested in all the types of kryptonite hunt for them, especially if they don't know that some of them exist. This is an encyclopedia entry on kryptonite and should include all of the varieties, wheter real or fake, Crisis or pre-Crisis.RandallFlagg 13:18, 18 November 2005 (UTC)
However they are not useful for anything. There is no reason to link to the various colors. If they were linking to pictures of the various Kryptonite’s I could understand. However, how it is its just linking to the colors themselves and is of no real use.Whispering 19:00, 18 November 2005 (UTC)
You're right. I misunderstood. Thought you were getting rid of the whole section. My mistake.
Not really color links but it should be under links anyway. So I'm going to drop it under here anyway. I'm going to keep editing out the less than useful links. I for one don't like reading a blue word every other sentence it's rather disconcerting. Whispering 04:31, 22 November 2005 (UTC)

The "science" behind kryptonite[edit]

Some one smarter than me needs to edit this section. As is I can only read about half of it before my brain reaches meltdown. Some how we need to make it more clear and put it in layman's terms or get rid of it entirely. Just a little addon I removed the ISBN because it wasn't really linking to anywhere useful. Whispering 00:38, 18 November 2005 (UTC)

I just put a confusing template on the "science" behind kryptonite section. How it is rather confusing still. Whispering 00:07, 4 March 2006 (UTC)

It's not just confusing, it's mostly nonsensical. This section is in need of a major overhaul, or else it should be jettisoned completely. At any rate, the section seems to have been written as if the author thinks kryptonite is real. This article is about a work of fiction, NOT about a real substance. The questions regarding kryptonite are to be settled based on testimony from the series and/or its creators, not fan speculation ("speculation" is, after all, impossible when its subject does not really exist). Chalkieperfect 03:44, 18 February 2007 (UTC)

doesnt the "ite" in kryptonite come about cause its metorite?

NO the "ite" at the end is a common suffix meaning a compound containing stuff like hematite or bauxite. —Preceding unsigned comment added by (talk) 05:01, 26 January 2009 (UTC)

I took 2 screen shots in the movie that illustrates the origin and composition. Someone with an account can upload them if you choose to:


The original term used by Siegel and Shuster when the concept of kryptonite was 1st formed was called "K-Metal". You can find out much more about this and the original story that was never published at [1]. The preceding unsigned comment was added by (talk • contribs) .

This is already mentioned in the third paragraph of the article. Thanks for the link, though, I'll add it to the external links. Bryan 07:22, 2 February 2006 (UTC)

"Purple Kryptonite"[edit]

After weeks of searching, I finally found the source of the apocryphal "Purple Kryptonite" entry causing much discussion on the web. Whoever inserted it originally was misremembering a story from SUPERMAN #371 where Superman was given temporary mind-over-matter powers by the rays of a purple SUN. Have since edited out the Purple K reference.

--Mark Waid

Thanks for the edit! Also, in the future, you can sign your name by putting four "~" symbols (no spaces) at the end of your post (though this'd require you to register/log in first). Anthony Dean 01:34, 7 April 2006 (UTC)
I sifted throught the google results for "purple kryptonite" and patterns start to form. Purple Kryptonite seems to have become something of a meme - it's the one fans refer to when they want to make a joke or a comment, but don't want to reference an "existing" kryptonite. It seems to get confused with Pink Kryptonite quite often or with the black kryptonite from Smallville. It may have appeared in the Krypto cartoon where it "makes him chase his tail."[2] The adult fan fiction community also seem to think it affects a human's sex drive. --Jason Kirk 11:03, 11 April 2006 (UTC)
If that was really THE Mark Waid, Mark Waid doesn't have to sign in if Mark Waid doesn't want to. Although I have my doubts, the real Mark Waid would have access to Superman #371 (as well as all others). (talk) 19:16, 30 January 2008 (UTC)


"Kryptonite is also another reference to the 2005-2006 George Mason University's Mens Basketball team. Other teams who thought they were supermen were no match for Mason's Kryptonite. The only thing that can defeat kryptonite is the extreme ugliness of another team."

What relevance does this section have to the DC Comics substance? Remove?

None... already removed. Anthony Dean 03:38, 12 April 2006 (UTC)


I noticed that the effects of lead on Kryptonite does not seem to be in the entry at all, except for a quick reference towards the end. I threw in a mention under "Green Kryptonite." Dustinroolez 17:03, 3 June 2006 (EST)

I did mention that imperfect duplicated Blue Kryptonite rays are only blocked by imperfect duplicated lead. The Blue radiation passes right through real lead. So does the rays of Red K in some early stories. No real word yet on White K or Jewel K or Kryptonite Fire or artificial, imaginary yellow K.

The Big Couldn't[edit]

I was just looking through the article and found this sentence under Blue Kryptonite 'In ML Thompson's Lois & Clark story "The Big Couldn't" it causes erectile dysfunction (impotence).' I was intrigued and I looked it up. I can't find any reference to it. I did, however, find a reference to the author as a fanfiction writer.

If this is the case, should this be in here?--Jcvamp 02:42, 17 July 2006 (UTC)

Page Move[edit]

There is supposed to be a discussion on this page about merging Kryptonite in Smallville into this page. I cannot find a discussion anywhere, but I think that it is appropriate for it to be on this page. Bignole 20:32, 21 August 2006 (UTC)

Old Kryptonite[edit]

Can somebody confirm the date of intro? Daniels says it was 1945, not 1943. Trekphiler 07:05, 16 October 2006 (UTC)

I answered this at Talk:Superman#Old Kryptonite. Bottom line: whoever or whatever this "Daniels" is, don't trust him/her/it/them. --Joe Sewell 16:48, 16 October 2006 (UTC)
Daniels, in the this content almost certainly refers to Les Daniels, author of several coffee table books about DC and Marvel comics including Superman: The Complete History. In there is an actually references 1943 as the radio origin, but he says that its 1945 appearance was "Radio's most dramatic use of kryptonite." He also notes the unpublished 1940 K-metal story. --Jason Kirk 20:03, 16 October 2006 (UTC)


"Product names and/or code names of AMD processors consist of the format "Kx", where the letter "K" is a reference to Kryptonite and "x" is a number that represents the generation of processor. This is a clear reference to that Intel is dominant in the CPU market and AMD seeks to be a viable competitor to Intel."

How is this a clear reference? I don't see any sources for this assumption, either. Should it be erased from the article? 07:52, 22 October 2006 (UTC) M

The article on AMD cites a Forbes article. -- 01:55, 11 August 2007 (UTC)


Although it is often cited as being deadly, are there any canonical examples of Kryptonians dying by Kryptonite exposure? —Preceding unsigned comment added by (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 (talk) 05:09, 26 January 2009 (UTC)


The website Superdickery archives quite a number of Superman covers, many of which showcase what happens to Superman, Jimmy Olsen, etc., when exposed to Kryptonite. A few months ago, I tossed in the external link to the Superdickery page about Pink Kryptonite to substantiate the reference. I will be posting a links to Superdickery both in See also and in External links. I know, they're horribly irreverent, and not encyclopedic in nature, BUT they are highly relevant for this page. If you feel like removing them, please discuss it here first. samwaltz 20:48, 5 April 2007 (UTC)

Kryptonite found[edit]

Someone might want to add stuff from this article. --SLi 00:14, 24 April 2007 (UTC)

I'm wondering if nearly as much space should be devoted to this. Considering that the "formua" in Superman Returns is so obviously contradictory to the rest of the Superman canon anyways. Octan 23:50, 24 April 2007 (UTC)


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")? — 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)

Kryptonite in Serbia?[edit]

Please be kind, I don't know how to use the talk page. However, you may want to know that "Kryptonite" has actually been found in Serbia. Link to the BBC story 'Kryptonite' discovered in mine

This is jadarite, which journalists have deliberately (but incorrectly) termed "kryptonite" because of the similarity between the chemical formulae of the two substances. — Paul G 08:35, 24 April 2007 (UTC)

Here is another link I found on Yahoo! the Kryptonite cheetahman2006 10:22, 24 April 2007 (UTC)

I've cleaned the section on the serbian "kryptonite" - I suggest a section header change to something a little more encyclopaedic. I removed the first section, as it was little more than a cut & paste. - Tiswas(t/c) 09:03, 24 April 2007 (UTC)

-According to the article above, the "Kryptonite" is a compound that has nothing to do with Krypton- the element. I was shocked when I heard someone found "Kryptonite" because Krypton is a noble gas and if they really found "kyptonite" then there could be Heliumnite! and that would be very useful! since is lighter than air.--Wxyrty 00:19, 25 April 2007 (UTC)

Calling Jadarite Kryptonite (as is currently done at the beginning of the article) is incorrect. According to one scene in the movie Superman Returns, Kryptonite is composed of "sodium lithium boron silicate hydroxide with fluorine;" but Jadarite has no fluorine in it. Other formulas for Kryptonite have been given in other media, and this is really just the news trying to make a story out of a minor coincidence. I doubt that the formula given in the movie is even correct. The nature of Kryptonite as it is explained in the comicbooks should take precedence. But even if the movie is to be considered relevant, that composition was determined by Earth scientists attemping to examine an unknown alien substance and they were probably wrong. They most likely also missed the radiation aspect. -- Macduff 21:16, 25 April 2007 (UTC)

I have created article. Kryptonite (real) not a good name. I know. I will add material in it tomorrow because I have to catch last train of the day. Please update (move around) it. --- ALM 20:57, 26 April 2007 (UTC)

Some additional out of universe material[edit]

(For those that don't know the distinction between out of universe and in universe, see Wikipedia:Manual_of_Style_(writing_about_fiction).) Generally, I think this article has a nice balance, but what about adding how Kryptonite was created for the movie? What special effects were used, if any, etc. Sancho 18:15, 23 May 2007 (UTC)

I seem to remember there being a table of the colors and effects in the Variations section. As it stands, only a list of artificial and fake kryptonite shows up.

I used an old version of the table to fix the problem. I think what must have happened is that someone made additions to the table and some how deleted important code. Since my knowledge of wikicode is limited I just used an old version of the table from about a year ago. If there needs to be info added to it from a later edition of the table, go ahead and change it. just make sure that the table actually shows up when you preview it before making the change. -IthinkIwannaLeia.

This article is gigantic. It seems to contain a vast amount of information about almost every single appearance of kryptonite in every medium it has appeared; the capitalisation of "kryptonite" (which 1. is a mineral, not a proper noun and 2. does not have a capital letter in the comics) wanders; there is a lot of duplication of information between the list of types of K and the list of depictions in media. Both of these are unnecessarily detailed. I have been trying to pare it down to broad strokes without removing too much information, which is possible, because the article is currently very verbose. Please don't just arbitrarily revert the article back to its bloated state. -- SamSim (talk) 21:58, 2 February 2008 (UTC)

So you don't want the data on the only two appearances of artificial imaginary yellow kryptonite? Is this a space thing or a we just don't care thing? An early Lois Lane letter-of-comments page answer gives the origin of green K as normal rocks from the explosion of Krypton that passed through a glowing green radioactive cloud in space. Should that be included? I put the use by Lex Luthor of addressing the citizens of the bottle city of Kandor as, "Kryptonites!" is that too long. What is our goal here, an overview or some type of encyclopedic coverage of the topic? Ken Rowand```` —Preceding unsigned comment added by (talk) 05:17, 26 January 2009 (UTC)

Clear Kryptonite[edit]

On an early episode of Smallville, there is a clear piece of kryptonite on a chain that has been drained of all its power and has no effect whatsoever on anyone, including Superman. (talk) 18:47, 1 March 2008 (UTC)

Lable in Superman Returns[edit]

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[edit]

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. 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[edit]

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. (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[edit]

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 (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)

Gemstone kryptonite[edit]

"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? (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[edit]

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 (talkcontribs) 21:08, 24 January 2011 (UTC)

When was kryptonite introduced to the storylines?[edit]

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)

Empty Nest[edit]

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[edit]

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. (talk) 02:39, 2 April 2012 (UTC)

"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 (talk) 06:55, 31 May 2013 (UTC)

Red Kryptonite -Smallville[edit]

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


Smallville red Kryptonite requires close contact with skin to be effective, such as being worn in a ring or necklace. [1]

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. [1],[2]

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)

  1. ^ a b Smallville, Episode 02x04 "Red"
  2. ^ Smallville, Episode 02x14 "Rush"
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[edit]

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 (talk) 11:30, 27 January 2015 (UTC)

Forming black kryptonite[edit]

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.( (talk) 19:17, 27 October 2015 (UTC))

Ant Kryptonite[edit]

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.-- (talk) 01:04, 3 April 2016 (UTC)
