->''"Reactions resulted in the product being coined 'Krazy Glue'; a product so crazy that it requires intentional misspelling."''
-->-- '''Website/{{Cracked}}''', "[[http://www.cracked.com/article_17134_5-accidental-inventions-that-changed-world.html 5 Accidental Inventions That Changed the World]]"

[[SelfDemonstratingArticle Certain letterz of the English alphabetz are just "kewler" than others]]. As such, many peoplez will intentionalli mizzpel wordz by xubztituting ðese letterz, in the hopez that this will draw moar attentshun from young peoplez and make the rezult look moar youþ-oriented.

Whether this actually ''works'' on the youth crowd is debatable; this is a pop-culture phenomenon that [[CyclicTrope comes and goes]] like many other fads, sometimes [[TotallyRadical losing its appeal]] almost immediately out of the gate.

Although, when it is used, it is often PlayedForLaughs to point out marketing groups that fail to understand an audience or, more often, weak attempts to seem hip to the younger generation.

The most common substitutionz are:
* "K" in place of a hard "C" (like in ''Franchise/MortalKombat'' and ''Music/{{Korn}}'')
** Note that this is often used to give characters that "medieval", "germanic", or "Soviet Russia" tinge. In actual German, however, spelling things with "C" instead of K (or Z, often seen in circuses spelling themselves "Circus" instead of the dictionary's "Zirkus") would have the exact same effect, or make words look old-fashioned (because they were written with C in former times).
** The reversal, substituting "C" instead of "K," is also very common in the Hip Hop community.
** Substituting "ck" for hard "c", especially at ends of words, also has a PhantasySpelling flavor.
* "X" substituted for "Ex," especially in the word "Extreme," or just slapped onto a name for no apparent reason.
** Also, "ix" substituted for "ics" or "icks" at the end of a word.
* "Y" instead of "I" in the myddle of a word.
* "I" instead of "Y" at the veri end of a word.
* "Z" instead of "S" at the end of plural wordz.
* "A" substituted for "er" or "or" at the end of a word.
* Spelling "cool" as "kool" or "kewl".
* Anything with AddedAlliterativeAppeal, such as "Kool Kids".

Less-common variantz include:
* Letters2Numbers, like "2" in the place of "to" or "too".
* [[FunetikAksent Phonetic spelling]]; for example, inserting "-shun" in place of "-tion" or its kin: "Acshun!"
* [[TheBackwardsR Substituting letters from foreign alphabets in place of English letters]], regardless of whether that letter has any similarity in pronunciation or meaning.

Interestingly, this trope tends to favor letters constructed primarily from hard straight lines and sharp angles -- "X," "K," "Z," so on. These letters are also worth many points in English-language ''Scrabble'', though examples of this trope would probably not be considered legal words.

This can also extend to acronyms/abbreviations/initializations to make them more memorable, even if the chosen letter isn't, technically, the one in the original word. "X-Tensible Markup Language," for example, is easier to remember by its initialization of "XML" than "EML".

"[[LeetLingo Leet speak]]" (or "1337") can be considered this trope played to extremes, where almost every normal letter is replaced by some form of "extreme" counterpart, which to those unfamiliar with the meme can vary anywhere from "slightly different" to "utterly unreadable," depending on how "hardcore" the user wishes to appear; it's believed that leet originated from the cracking[[note]]"Hacker" is a case of YouKeepUsingThatWord[[/note]] community, which may explain why it's never spread beyond circles of computer geeks, online gamers, and {{Homestuck}}s.

"Text speak," originating in IM and a popular shorthand for use with mobile phones, is similar to "1337," though the hardcore consider it a different language.

One possible justification for Xtreme Kool Letterz in RealLife is that, at least in the United States, "common words" cannot be trademarked as-is, but deliberate misspellings can.

The overall trope is OlderThanTelevision, and possibly OlderThanRadio, with deliberate misspellings being used for humor at least since the Victorian era. (And back then, of course, semiliteracy was such a problem that many otherwise articulate people ''unintentionally'' misspelled words, making this trope not only comical but also satirical.) In academic study of English, this is known as "sensational spelling".

Xtreme Kool Letterz shows up around this wiki as well, with titles such as DarthWiki/FriendsOfReallyKoolSobriquet, and yes, [[ThisTropeNameReferencesItself this article]].

Compare TheBackwardsR, DoubleX, HeavyMetalUmlaut, Letters2Numbers, LuckyCharmsTitle, MyspeldRokband, XMakesAnythingCool (for "X" used by itself), YeOldeButcheredeEnglishe, and more from the TextTropes index.

* Early advertising example: A 1950s print ad for Heinz baked beans included the caption, "Beanz Buildz Kidz!" And that wasn't even their main slogan... it was "Beanz Meanz Heinz".[[note]]That was probably unintentional in terms of Xtremeness, seeing as how the brand name is, of course, Heinz, and the ad was just a play on it, not on [=Sup4 Kule L3tt4rz=].[[/note]]
* The soda MDX, which stands for Mountain Dew Xtreme.
* ''Franchise/{{Bratz}}'' (doll lines, animated series, [=DVDs=]) totally qualifies. Not just with the name, but the name of ''every single doll line they have''. Doll names with a short '''I''' also have a double '''II''' for no apparent reason. Once they got to stringing together names like "Bratz Babyz Ponyz," you get to wondering how much longer until they trademarked the letter z and we'd all have to start paying them to be able to use it.
** One Bratz book is actually named ''Xtreme Kool''.
* Sprint's new [=WiMax=] service will be called "XOHM" (pronounced Zoam). ''"It's an invented term that went through extensive market research and tested well with consumer and business audiences," said Sprint's John Polivka. "There is a certain 'cool factor' with the X in it..." [[http://www.bizjournals.com/baltimore/stories/2007/08/13/daily34.html (source)]]
* Sheetz convenience stores have a fast food counter that sells "Bagelz" and "Wrapz".
* Intel's Xeon processors -- oddly enough, not really targeted at the "extreme" gaming crowd (they're mostly designed for use in commercial servers, where their support for multiple sockets, multiple CPUs per socket, and error-correcting memory are more useful).
* The Kia Forte is available as a four door sedan, or as a two door Koup.
* There are "freeline skates" with the brand name ''Xliders'' as well as a pumped-up Razor scooter called a ''Xootr''.
* As of 2008, the packaging and advertising for Goldfish snack crackers features four [[LetsMeetTheMeat anthropomorphic crackers]] as {{mascot}}s. One of these cracker characters is named Xtreme.
* According to Wiki/{{Wikipedia}}, KoolAid (originally Kool-Ade) was first sold in 1927, and Kool cigarettes were first sold in 1933.
* The banners on this page right now, which, many thanks to Ads by Google, are currently "XTREME Ringtones," "Xtreme Machine Wheels" and "Xtreme Diesel Performance."
* Many things marketed to kids seem to use this trope, probably in an attempt to make their product seem "cooler".
** Kidz Bop probably falls under this category
** "[[PhoneNumberJingle 1-877-]]Kars-4-Kids. [[SpellingSong K-A-R-S]], Kars-4-Kids..."
* There used to be a cider called "Xider". It may intend to evoke an American pronunciation of "exciter," but everyone around Sweden just said "kseeder". Then regulations changed and the stuff could no longer be legally referred to as a cider, so they changed the name to "Xide," whatever that's supposed to mean.
* Trix, and Kix.
* The next big global compact sedan from General Motors is sold in Europe, and will be sold in the U.S., as the [[http://en.wikipedia.org/wiki/Chevrolet_Cruze Chevrolet Cruze.]]
* Officially, the name of Elon Musk's private spaceflight company is Space Exploration Technologies, but they use "SpaceX" because it just sounds cooler.
* UsefulNotes/PlaystationNetwork has a sort of video-magazine entitled Qore (Core).
* Even fairly mundane things like public transport follow this trope. The transport manufacturer Bombardier is particularly fond.
** They have the "Flexity" tram and the "CX-100" people mover as two examples. Just to really make sure they keep this trope, most of their vehicles run on FLEXX bogies (or trucks). The fact one version is the FLEXX Eco is a trope in itself, as these days it's cool to be "eco".
** Also from Bombardier, the TRAXX locomotive. "Stands for Transnational Railway Applications with eXtreme fleXibility." TRAEF would not have sounded anything like as good.
* UNIX got its name when Unics became a NonindicativeName by no longer being a uniplexing (i.e. one thing at a time) system.
* Although it wasn't named this way for kewlness, Cheez Whiz[[note]]products must meet certain criteria to legally be called "cheese"; "cheez" has no such restrictions[[/note]] definitely fits the spelling pattern.
* Pringles "[[http://www.pringles.com/en_us/Pages/Xtreme.aspx Xtreme]]" flavors.
* [=DiGiorno=] Pizza & [[http://www.digiorno.com/Wyngz.aspx Wyngz]]. They actually couldn't legally call them "wings" due to the absence of any actual wing meat.
* The "ambient electronic device" [[http://www.karotz.com/home?locale=en_GB Karotz]], successor to the [[http://en.wikipedia.org/wiki/Nabaztag Nabaztag]].
* Springfield Armory Company imports the Croatian-made HS-2000 handgun into the U.S. and sells it under the name "Springfield XD". The "XD" is short for "eXtreme Duty".
* The fast food chain Zaxby's replaces "S" with "Z" at the end of words, bar their chicken wings, because [[LiteCreme "wingz" implies they aren't actually chicken wings]]. Appetizers is turned into Zappetizers, as well.
* King Kullen, one of the first self-service markets. Buy one and get AddedAlliterativeAppeal for free. (Or the other way round.)
* As a general thing, commercial products are more likely to use this trope because the more unique a name, the easier it is to trademark. Notice all the ''Transformers'' toys, for example, that bear either completely made-up names (Optimus Prime, Megatron) or names following this trope (Spittor, Demolishor, etc).
* In 1990, [[https://www.youtube.com/watch?v=ET8QzgFo5zg Pfister]] was billed as "The pfabulous pfaucet with the pfunny name."
* Irn Bru, Scotland's most popular carbonated drink and hangover remedy, is actually [[EnforcedTrope an involuntary example]]. The Advertising Standards Agency wanted Barr Soft Drinks to change the name from "Iron Brew" lest it mislead people into trying to use it as an over-the-counter anaemia remedy, but Barr had based their campaign on the fact the new drink was a similar colour to iron ore and gone all-out with the ForgingScene imagery for the TV spots etc, and didn't want to have to start over from scratch. A compromise was reached by spelling the name phonetically, and the rest is history.

[[folder:Animez & Mangaz]]
* The official English translation of the ''Manga/{{Bokurano}}'' manga explains the name "Zearth" by invoking this trope (justified, in that it's a bunch of kids piloting the robot). It is worth noting that the ''real'' reason for the name Zearth is that it's the Japanese pronunciation of "The Earth" rendered back into English (well, it's close to it anyway). On the one hand, even in a direct translation, the kids did go with "Zearth" instead of "The Earth" because it sounded cooler. On the other, has anyone ever actually said "the z makes it more extreme!" with a straight face? [[CrapsackWorld In the world of]] ''Bokurano'' they might.
* Franchise/{{Transformers}} examples:
** "Lazorbeak" from ''WesternAnimation/BeastWars''. (The Generation 1 character is always spelled "Laserbeak," as are the Cybertron and Animated ones. Expect a lot of people to get it wrong anyways.)
* ''Manga/IkkiTousen'''s fourth season, ''Xtreme Xecutor''
* Franchise/{{Digimon}} examples:
** ''Anime/DigimonXrosWars'', the sixth series of the franchise, and its sequel ''Anime/DigimonXrosWarsTheYoungHuntersLeapingThroughTime''. It's supposed to have a connection to the [[CombiningMecha DigiXros functionality]] in the series, which is, much as you'd guess, visually represented by an X.
*** "Xros" is still pronounced exactly like "cross" though.
** [=RizeGreymon=] in ''Anime/DigimonSavers''.
*** [[ZigzaggingTrope Some sources still spell his name with an 'S' though]]. This is more due to Japanese inconsistency with pronunciation vs. katakana.
** Khaosmon and UltimateKhaosmon.
*** This is more weirdness with translation, but referencing Greek as the origin point.
* The anime ''Anime/{{Texhnolyze}}''.
* The Japanese title of ''Anime/IlSolePenetraLeIllusioni'' (幻影ヲ駆ケル太陽) uses katakana where hiragana would normally be used.
* ''Anime/SenkiZesshouSymphogear G'': Kirika's attack names are spelled in a bizarre mishmash of randomly-sized Japanese and English characters, written in neon-colored "violent" calligraphy and accompanied by the sound of a witch's cackling. This is fitting for her nature as a {{Cloudcuckoolander}} and a massive {{chuuni|byou}}.

[[folder:Kard Gamez]]
* ''TabletopGame/YuGiOh'' card game:
** It includes a card called [[http://yugioh.wikia.com/wiki/Mind_Haxorz Mind Haxorz]] in the set ''Rise of Destiny''. Really! It's fun to mention that the original Japanese name of the card is merely "Mind Hack".
** We also have [[http://yugioh.wikia.com/wiki/Meklord_Astro_Machinicle Meklord Astro Mekanikle]]. Deserves special mentions because in ''Anime/YuGiOh5Ds'' it's the trump card used by the ''villain''.
** {{Invoked|Trope}} with the Xyz monsters introduced in ''Anime/YuGiOhZEXAL'' and the card sets. It's pronounced "ik-seez" and is a reference to spacial coordinates[[note]]three dimensions: its place on the mat, and the cards under it[[/note]]. Humorously, up to the point of their announcement in the TCG, fansubbers of the show never caught that meaning, assuming it was "Exceed" because it was the closest-sounding actual word.
* ''TabletopGame/MagicTheGathering'''s Phyrexia, with names like Gix, Xantcha, and Skithiryx. As Tom [=LaPille=] [[http://www.wizards.com/Magic/Magazine/Article.aspx?x=mtg/daily/ld/110 puts it]], "Are you more intimidated by the thought of the dread reign of Firecsia or Phyrexia?"

[[folder:Komix Bookz]]
* ''ComicBook/XMen'' examples:
** ''X-Treme X-Men''. Generally considered a really silly title, one online reviewer referred to the first three issues as ''That [[Creator/ChrisClaremont Claremont]] Book''. Ironically, when, after 46 issues, the book was canceled and the writer moved the characters to ''ComicBook/UncannyXMen'', the team was renamed "X-Treme Sanctions Executive."
** "Storm claims it was an inside joke, and blames Gambit. Gambit blames Rogue. I blame society." -- Cable, ''X-Men: Future History - The Messiah War Sourcebook''.
*** It helps that the initials XSE also match the team Bishop was part of in his BadFuture: the Xavier Security Enforcers. The name ''really'' exists so Bishop can go "OhCrap, the XSE! It's coming true after all."
** Arguably, the ComicBook/XMen themselves. In the first issue, Professor Xavier notes that it stands for "X-tra power!" Fortunately, it's been {{retcon}}ned to stand for both Xavier's name and the X Factor, the unknown genetic factor that gives mutants their powers.
** And then there's Professor Xavier's name:
*** There's all the adaptations that pronounce it "Professor Ex-avier," just to make it clear to stupid viewers that there's an X in his name. "Xavier" is an archaic Spanish spelling of "Javier," so it should be "khavi-air" (or "zavvy-ay", in French), people. ("Ex-avier" is a common (mis)pronunciation of "Xavier" in RealLife, though).
*** The Spanish dubs fortunately make a point of pronouncing his name "Xavi-air".
*** There is a comic where Xavier admits that ''technically'' it isn't pronounced like that -- he just prefers it.
** And the ''ComicBook/XMen'' spin-off book ''ComicBook/XForce'' once had a character called Adam-X, the X-Treme. Ah, the '90s. Thankfully, "the X-Treme" part rarely appeared outside of cover announcements of his guest appearances.
** Before Adam-X, there was ComicBook/IllyanaRasputin, aka Magik. Although ''magik'', pronounced with a long 'a' and a hard 'g', is an actual word in Russian; it means "magician". The question is if Chris Claremont knew that when he gave the Siberian mutant that name.
** Even earlier, there was Alex Summers, aka Havok.
** Played with in two spin-off titles launched by Creator/ChrisClaremont, ''Excalibur'' and ''[=GeNext=]''. In both cases the "X" was the biggest letter in the cover logo. It went even further in the ''ComicBook/{{Age of Apocalypse}}'' crossover in the 90's, when ''Excalibur'' became X-Calibre.
** Averted in the first arc in Creator/GrantMorrison's ''ComicBook/NewXMen'' run, which was titled "E is for Extinction." Let's just say that another writer might have emphasized a different letter of that word. [[spoiler:Except that the "X-tinction" title had already been used multiple times throughout the history of the team. He probably just wasn't allowed to use it again.]]
** When the second incarnation of the ''X-Force'' was threatened with legal action over their name, leader the Orphan simply changes it -- to "ComicBook/XStatix". He says it came to him in a dream and he doesn't really know what it's supposed to mean.
** This was a subject of a TakeThat moment in an issue of ''ComicBook/BloodSyndicate''. A RealityWarper villain briefly caused the team to transform into parodies of the X-Men and X-Force, and as such, everyone now had ridiculously misspelled names. Brickhouse became "Brique," DMZ became "Mister Ree," Flashback became "Regrette," Kwai became "Kwiklash," and so on.
* In the second issue of ''Hyperkind'', one of the newly empowered Hyperkind decides to adopt "Logic" as his CodeName. Another member (the resident comic nerd of the team) stops him, telling him to call himself "Logix" because, "That's how it's done!" Said comic nerd then decides to call himself Amokk, for the same reason.
* In ''Comicbook/TheLeagueOfExtraordinaryGentlemenBlackDossier'', Mina delivers a TakeThat to the producers of the ''League of Extraordinary Gentleman'' movie when she identifies a rocket as being American because "who else would think that "extra" starts with an "X"?" The League movie was often referred to as ''LXG''.
* In Franchise/TheDCU:
** The hero ComicBook/{{Aztek}} was named by a newspaper. Drawing on the South American motif in his costume, a reporter dubbed him Aztek "with a 'K' -- because of all the neat high-tech stuff he's got on his uniform."
** Kobra
* Underground Comix. So called to distinguish them from mainstream comics.
* ''[[ComicBook/{{Miracleman}} Kimota!]]'' ("Atomik" spelled backwards).
* In the weekly AnthologyComic ''ComicBook/TheBeano'', there is comic strip entitled ''Ratz''.
* ComicBook/CaptainAmerica of Marvel's Super Soldier program was Weapon 1. 40 years later came the last major Super Soldier trial: [[ComicBook/XMen Weapon X]].
* The AnthologyComic ''Comicbook/TheDandy'' was reinvented as ''Dandy Xtreme'' in TheOughts. It reverted back to being ''The Dandy'' at the start of TheNewTens for its final years as a print comic.
* This trope was popular during UsefulNotes/TheDarkAgeOfComicBooks and the Speculator Boom when comic creators were looking to make a quick buck off of original characters. The reasoning for using Xtreme Kool Letterz at this time was likely done to help insure that whatever name a creator came up with for their NinetiesAntiHero could be trademark/copywrited. You can't retain the rights to "Strike", but you can retain the rights to "Stryke".
** Although Creator/StanLee and Creator/JackKirby (the creator of "[[AddedAlliterativeAppeal Kirby Krackle]]") also indulged in this, e. g. with names like Klaw, Kalibak and Apokolips (this last one replacing a 'y' with an 'i'). Other Marvel examples from the 1970s and 1980s include Deathlok the Demolisher, Drax the Destroyer, Karisma, Mahkizmo, Nekra, Terrax the Tamer and Terrex. Also, Creator/FrankMiller called Daredevil's first love ComicBook/{{Elektra}}, while "Electra" is the more common spelling in English; however it was justified by making her Greek.
* There was a short lived company in (of course) TheNineties making creator-owned sci-fi comics under the banner of Tekno Comix.

[[folder:Fan Workz]]
* In ''[[Fanfic/TotalDramaComebackSeries Total Drama Comeback]]'', Chris attempts to apply the C->K variant to the Cool Kids' Club. The campers [[DudeNotFunny react badly]], and even Chris seems horrified when he realizes the UnfortunateImplications.
* ''Fanfic/CalvinAndHobbesGetXtreme''.
* "Karlix" from ''FanFic/PrettyCurePerfumePreppy'' is actually just the word "garlic" (or even the plural "garlics") with this invoked.

[[folder:Filmz -- Anym@tion]]
* ''WesternAnimation/{{Antz}}'' can be read as a misspelling of "ants", [[DoubleMeaningTitle but also as]] "Ant Z" ([[CharacterTitle referring to the protagonist]], an ant [[OneLetterName named "Z"]]). For this reason, it's often stylised as "[=AntZ=]".

[[folder:Filmz -- Lyve-Aktion]]
* The 1950 film ''Film/RocketshipXM'', where the titular spaceship's name is short for "Expeditionary Mission".
* When the teleplay ''Series/TheQuatermassExperiment'' was made into a film, it was titled ''Film/TheQuatermassXperiment'', apparently in reference to its BBFC X certificate (the film is nowadays rated PG).
* ''Film/{{eXistenZ}}'' could be justified because "Existenz" is the German word for existence and "isten" is Hungarian for "God," giving the director a reason to frame it with Caps.
* ''Series/DaAliGShow'' is a chronic abuser of this, with such recurring words like "Respek" being used intentionally by the titular character, who referenced that all respect had been lost in the world since [[TooDumbToLive the word "respek" had been removed from the dictionary]]. [[RuleOfFunny But of course...]]
* The marketing for ''Film/TheLeagueOfExtraordinaryGentlemen'' used the acronym "LXG". Didn't help the movie either.
* From the silent movies, the ''Keystone Kops'' were the inspiration for many later examples. Although at this time, K's weren't meaning "cool," but rather "funny," as in "ha ha, those guys can't spell correctly."
* The titles of the hood classics ''Film/BoyzNTheHood'' and ''Film/MenaceIISociety''.
* ''Film/{{Zardoz}}'' has some curious spelling like this, but it seems to be meant more as Futuristic Fonetiks ("applz" for "apples"). Not to mention the revelation that [[spoiler:it's actually ''The Wi'''zard''' of '''Oz'''.'']]
* ''Film/AmericanDreamz'' parodies this. The title is the name of the show-within-a-show, an ''Series/AmericanIdol'' [[NoCelebritiesWereHarmed knockoff]] with a contestant played by Music/MandyMoore, who at one point sings a ridiculously vapid ballad with the chorus, "American Dreamz... ''dreamz''... with a ''Z''."
* In ''Each to His Own'', Olivia [=DeHavilland's=] character makes her fortune as selling "Lady Vyvyan" cosmetics. As her lowlife partner remarks "Classy, hunh?"
* ''Film/BillAndTedsExcellentAdventure'': Wyld Stallyns!! Played for laughs, of course.
* The "Rekall" brand in ''Film/TotalRecall1990'' and [[Film/TotalRecall2012 the remake]].
* The religious film ''Film/CMeDance''.
* While HeavyMetalUmlaut is a case of "everything's cooler with umlauts," ''Film/ThisIsSpinalTap'' takes it, like many other things, UpToEleven: the trema in the band's logo is not even over a ''vowel'', but rests proudly atop the letter N.
* The title of the direct-to-DVD kid flick ''Film/EZMoney'' and the Ez Loan company featured within it.
* Pixxi de la Chasse in ''Film/RepoChick.'' Her parents obviously didn't think that Pixie was Xxtreme enough.
* The low-budget direct-to-video 2004 film ''Film/{{Vampiyaz}}'', about urban bloodsuckers.
* ''Film/IndependenceDay'' was widely marketed in posters and toys as [=ID4=] - despite the fact that the inclusion of the '4' is completely redundant.

* ''Literature/{{Discworld}}'':
** In ''Discworld/SoulMusic'', an all-troll Music With Rocks In It band want to call themselves simply "Trolls" they're told, "But you've got to spell it with a Z. Trollz." [[HilariousInHindsight Funnily enough]], on a non-''Discworld'' note, when the Trolls doll line was revived for the 21st century (along with an animated series), the powers that be [[http://www.trollz.com/ did just that]].
** The vampires in ''Discworld/CarpeJugulum'' express a desire to [[PhantasySpelling spell it "vampyres"]], as the Y makes it look more modern. Even though said spelling is probably [[OlderThanTheyThink older]].
** Dr. Hix in ''Discworld/UnseenAcademicals'', head of the Department of [[{{Necromancer}} Postmortem Communications]], is really named Hicks, but with his black robe and skull ring he "would have been mad, or let us say even madder, to pass up a chance to have an X in his name." (This actually goes along with a change in his character; he appears first in ''Discworld/MakingMoney'' but there is more sheepish and actually cares about the rules, and is still spelled Dr. Hicks. Apparently his CardCarryingVillain, by university statute, personality came with the placement of an X in his name.)
** Agnes Nitt's alter ego Perdita has the middle initial X, which stands for "a person who has a cool and exciting middle name."
** And of course, there's the whole continent called XXXX. But pronounced "Fourecks" (and named after a RealLife brand of Australian lager).
* The ''Matthew Martin'' series by Paula Danziger features a character who spells her name "Jil!" because she got bored with "Jill."
** Another children's book has a character named Susan who changes her name to, well, the title says it all: ''My Name is [=Sus5an=] Smith. The 5 is Silent.''
* Several names in ''Literature/TheWheelOfTime'' are actually perfectly ordinary names that have been grossly misspelled. Examples include "Elayne" (Elaine), "Padraig" (Patrick), "Birgitte" (Bridget), and "Logain" (Logan).
** Well, to be fair, Padraig is a legitimate Irish variation of Patrick in its own right and Birgitte is a legitimate Scandinavian variant of Bridget. It should be noted that in the Norwegian translation of ''The Wheel of Time'', Birgitte's name is translated to the more exotic sounding Bergithe, as Birgitte is quite an usual name in Norway.
* Same goes for ''most'' personal names in ''Literature/ASongOfIceAndFire''. The letter "y" is particularly common.
** True for several titles as well. For example, "Ser" instead of "Sir". "Maester" instead of "Master".
* ''Literature/OryxAndCrake'' pictures a future where hyper-rich corporations call themselves things like [=HelthWyzer=] and [=RejooveNation=] with a straight face. It's never explained, but one gets the feeling they have been forced to come up with these "creative" spellings because all the normal ones had been trademarked. Unless they actually thought it sounded cool.
* Species in Creator/PeterDavid's ''Hidden Earth Chronicles'' include Mandraques, Firedraques and draqons.
* Rob Grant's ''Literature/{{Fat}}'' had a pop group parodying Girls Aloud by the name of "Gurlz Banned".
* One Franchise/DoctorWhoExpandedUniverse novel has a character being dubbed "code-boy" by another because he spends a lot of time doing computer programming. You know, writing code. He loses his real name and ends up known as Kode, likely because of this trope.
* In ''Literature/TheEdgeChronicles'', the academics of Sanctaphrax want to seem educated, and all the Leaguesmen want to sound like them. The result is a lot of polysyllabic names.
** There is also the species of cruel humanoid birds called "shrykes". They are obviously named after shrikes, birds widely known for impaling prey on thorns, only with a "y" instead.
* J.R. Ward's ''Literature/BlackDaggerBrotherhood'' series has a number of main characters with NamesToRunAwayFromReallyFast coupled with this sort of spelling. Some examples include: [[WhoNamesTheirKidDude Phury, Rhage, Zsadist, Rehvenge, and Tohrment.]]
* ''Literature/AConfusionOfPrinces'' uses this for the names of the three technologies in the Empire: Mektek, [[PsychicPowers Psitek]], and [[BioAugmentation Bitek]].
* Invoked in Creator/RayBradbury's short story "Literature/ASoundOfThunder." The bizarre spelling on the time-travel safari sign is the first clue the characters have that [[ButterflyOfDoom killing a butterfly in the past dramatically changed the future]].
* ''It All Started with Columbus'' credits the UsefulNotes/KuKluxKlan with the introduction of phonetic spelling, which "gave us such words as Kleenex, Krispies and ComicStrip/KrazyKat."
* ''Literature/DiaryOfAWimpyKid'':
** One brand of carrot sticks is Xtreme Sports Stix (despite them having nothing to do with sports).
** One book Greg's mother hates is called "Xtreme Pop-up Sharks".
** One comic strip mentioned is called "Xtreme [=Sk8ters=]". Another is "Action Fighterz", which features a character "Captain Klobber", another is "Wacky Dawg" and another is "Office Antix".
** A brand of shoes Greg buys is Sportsterz.

[[folder:Lyve-Aktion TV]]
* ''Series/AllInTheFamily'': In the episode "Archie and the KKK", the Kweens Kouncil of Krusaders organization that Archie considers joining goes ''only'' by this name ... but it becomes very obvious to Archie, once the group announces its plans to burn a cross on Mike's lawn (for writing an editorial with whom the group's members took issue), that this group is actually the Klu Klux Klan going by an alias.
* A late episode of ''Series/SabrinaTheTeenageWitch'' involved Sabrina, Roxie and Morgan forming a girl group called "Girlz." During their first audition, they think they can easily beat the guy who went on before them because they have a Z in their name; however, his name turns out to be Zeke.
* ''Series/StargateSG1'':
** Parodied in episode "Wormhole X-Treme," with the eponymous ShowWithinAShow. One character comments that he "wanted to call it ''Going to Other Planets'', but [[ExecutiveMeddling the network said]] that shows with 'X' in the name get better ratings."
** Of course, the titles of all Stargate series do the same thing, replacing the second "A" in "Stargate" with the gate symbol for Earth. Not mandatory, thankfully. Which, incidentally, is just an uppercase lambda with a krou�ek on top of it. A rather strange blend of a Greek letter with a Scandinavian diacritic (Å). It is described in-show as representing the sun rising above the Great Pyramid of Gizah.
*** However it was more likely a fluke that the symbol looks like a combination of those, even though it is "sort of" a letter in the cannon, as it did only "become" a letter in a much later episode where we find out the Ancients DID apply sounds to Stargate symbols anyway.
* Johnny Xtreme, one of the most recurrent non-intern (nor host, obviously) characters in ''Series/XPlay''. He was pretty much the AnthropomorphicPersonification of "extremeness." He even tattooed Xs onto his arms and cut his beard in X shape. Given the tone of the show, it is pretty certain that Adam or Morgan must have pointed out the fact that there was an "X" on their show's name for no real reason.
** In reality, the show started out as "Extended Play" and received a retitle when it was relaunched, reducing "Extended" to "X". ''XP'' was floated as a title before the producers realized people would be confused that it was a tech show about [[UsefulNotes/MicrosoftWindows Windows XP]].
** During a review of ''MortalKombat'', Adam and Morgan commented on the title, saying "everything is cooler when spelled with a K."
* ''[[Series/MostExtremeEliminationChallenge MXC: Most Xtreme Elimination Challenge]]''. Used tongue in cheek, since it's a GagDub show.
* The French series ''Series/{{Kaamelott}}'', parodying the Arthurian legends. A lone stylized "K" is also used prominently during the credits and even on fictitious heraldry. The author justifies this as being close to an ancient variant of spelling for "Camelot"; hence, here the effect aimed at isn't to look "cool" but "antiquated".
* The shameless cable network Creator/DisneyXD, which outright tells you they're both extreme and 'wit it', as the XD part is an "extreme!" emoticon denoting extreme happiness.
* Variant: On ''Series/TopGear'', their homebuilt electric car (the Hammerhead Eagle i-Thrust) was named with a [[IProduct lowercase "i"]] because it was the Xtreme Kool Letter for the eco-friendly set.
* Ed Helms filed a report on ''Series/TheDailyShow'' about an insurance made especially for teenagers and concluded with a fake ad that said it even covers you if you break your coccyx while skating -- spelled ''kokkyx''.
* ''Series/KamenRiderDouble'''s SuperMode is literally called [=CycloneJokerXtreme=]. This is primarily because the show's TransformationTrinket relies upon USB flash drive-like devices, each with a logo consisting of a stylized version first letter of its name that also represents its power (for example, a volcano shaped like an "M" for "Magma").
* On ''Series/BigTimeRush'', when James briefly joins Hawk Records, they change his name to Jamez. And as can be seen from the posters in their studio, all of their other artists have a 'Z' in their name too.
* In political satire ''Series/TheThickOfIt'', Emma wonders why people leaving hate mail on her boss Peter's blog spell "hate" as "h8". [[ComicallyMissingThePoint "If you're going to leave a message,]] [[YouMakeMeSic at least spell it correctly."]]
* ''Series/ThePriceIsRight'' has a pricing game called Eazy az 1 2 3.

* You think "Muzak" is just slang? Think again... it's originally a brand name, created in 1934, to sell background music to retail stores and other buildings.
* The KoreanPopMusic GirlGroup Music/{{Pristin}} used to be called Pledis Girlz. Siyeon's stage name is Xiyeon, making it ultra kewl.
* The record label Avex Trax, while Avex is an acronym of Audio Visual Label, the word Trax came from "tracks".
* The musical group Music/{{Gorillaz}}.
** Also, the film to go with it, ''Bananaz''.
** And the short non-clip animations are ''Gorillabitez''.
** And their fifth studio album, ''Humanz''.
* [[Music/{{Pink}} P!nk's]] album ''M!ssundaztood''. "P!nk" is more of a LuckyCharmsTitle.
* Music/KoolKeith
* Music/{{Kreator}}
* The Music/TheLonelyIsland songs ''Just 2 Guyz'', ''We Like Sportz'' and ''We'll Kill U''.
* Music/{{Megadeth}} is suppose to be spelled without a second "A".
* Music/KoolAndTheGang.
* During Music/ChristinaAguilera's "Dirrty" phase, she was usually referred to as "Xtina", because "X" is used as an abbreviation for "Christ" (as in "Xmas") for reasons dating back to Greek times -- in Greek, the name started with the letter chi, which looks like an X.
** Her 'Love Me 4 Me' uses extremely cool letters.
* Xzibit, or as he likes to say, "X to the Z Xzibit." Hell, one of his most famous songs is "'''X'''"!
* Rap group Onyx has their debut album titled "Bacdafucup" and their sophomore titled album "All We Got Iz Us", as well as a good number of their songs. Also, one of the members' name is Sticky Fingaz.
* French example: la [[http://en.wikipedia.org/wiki/Tecktonik Tecktonik]]. Xtreme Kool Letterz (in particular the use of "ck") is also very popular amongst its practitioners around the world, either for individual aliases or group names.
* The entire genre of jazz may owe its name to this. The name is derived from the Cajun patois word jass (referring to "strenuous activity" in general, and one activity in particular), and reputedly, it started being spelled with the double-z not only because "jazz" looked cooler, but more mundanely, at least in part because jokers kept stealing the letter J from the billboards.
* Music/KatyPerry has quite a few, "Hot N Cold", "Ur So Gay", and "California Gurls".
* The US PowerMetal band Kamelot. (And no, the Arthurian Camelot is usually spelled with a C in German.)
* [[Music/{{Metalocalypse}} Dethklok]] and to a lesser extent their "kvlt" spelling Dëthkløk.
* Those Y's guys from Pyrymyd.
* Strangely [[InvertedTrope inverted]] with the Japanese band Music/{{Polysics}}, whose name is based on a synthesizer named [[http://en.wikipedia.org/wiki/Korg_Polysix Korg Polysix]]
* Electronic artist [[http://en.wikipedia.org/wiki/Sasha_(DJ) Sasha's]] hard-to-pronounce remix compilation: Invol2ver.
* One of Enigma's latest [=CDs=] replaced the initial E with a Greek letter sigma. Sigma-nigma?
* The UK disco house label Hed Kandi, taking it to the vowels as well.
* British pagan rock band Inkubus Sukkubus. Technically, they were originally named Incubus Succubus, but changed it to Inkubus Sukkubus for "numerological reasons."
* Pick a nu metal band. ANY nu metal band.
** The UrExample, Music/{{Korn}}, or rather, KoЯn, used that to look childish - which is why the logo is crayon-like and has TheBackwardsR.
** Music/LimpBizkit's in da house y'all$.
* Music/PrimalScream's seventh album is a bit... conflicted about this. Its title is spelled ''XTRMNTR'' on the mostly vowelless album cover, but then again the band's name is similarly written "PRML SCRM" there, and ''Exterminator'' is written in some other places.
* Music/DefLeppard, whose name is misspelled to make them sound less punk.
* Music/LedZeppelin. Because their manager thought dropping the 'a' from Lead would help to prevent [[ViewersAreMorons "thick Americans"]] from pronouncing it "leed". Famously produced an album with a 'title' that could not be vocalised or spelled at all, only four symbols, which veers beyond this trope through LuckyCharmsTitle to TheUnpronounceable.
* Boyz II Men.
* For Synth musicians, most are familiar with these days with Yamaha XG Lite (that XG stands for Yamaha's proprietary eXtension to General MIDI, of course).
* Music/HelloProject group Berryz Koubou. ZYX also counts.
* A few songs by Swedish hair band Crashdïet, like Knokk 'Em Down and Breaking the Chainz.
* Music/AvrilLavigne's song "[=Sk8er=] Boi."
* Industrial bands in general love swapping "K" for "hard C."
* Music/{{Metallica}} sometimes spelled their names like this (Jaymz, Larz).''S&M'' does it [[http://www.ilbaluardo.com/Cover/Audio/M%20-%20N%20-%20O/METALLICA%20-%20S%20&%20M%20-%20Back.jpg for some songs]].
** Beatallica follows/parodies it. Their [[http://beatallica.org/lyrics.html lyrics]] are transcripted with gratuitous "Z" everywhere, and the band members are Music/TheBeatles + Music/{{Metallica}} mashups written with Xtreme Kool Letterz (Jaymz Lennfield, Grg Hammetson, Kliff [=McBurtney=], Ringo Larz).
* The American Hip Hop duo Music/{{OutKast}}.
* The acid house group Phuture
* The Southern California ska band Shame & Skandal.
* Music/{{Prince}} abused this a lot in his song titles (2 and U used wherever possible), combined with LuckyCharmsTitle (an eye-symbol for I), and he even wrote his lyrics and liner notes in Xtreme Kool Letterz. Famously swapped his own name for a [[TheUnpronounceable symbol]] that transcended this trope altogether.
* Music/{{Klymaxx}}, an all-female band best known for the soft rock single "I Miss You".
* An awful lot of songs by [[Music/TupacShakur 2Pac]]. 2pac himself was also an example, though rather than "to," it replaces "tu" (his real name was Tupac).
* Stewart Copeland, ex-Music/ThePolice drummer, in the first 2 years of band's existence, released some solo material under the name "Klark Kent." One of the songs was titled "[[http://www.youtube.com/watch?v=h92Z8Y1DjCA&fmt=18 Too Kool To Kalypso]]." On top of that, a CD compilation of Klark Kent material, released in 1995 was named "Kollected Works." And to top that all, his private little recording label is called "Kryptone Records."
* One of Music/LinkinPark's remix albums, [[http://en.wikipedia.org/wiki/Reanimation#Track_listing Reanimation]], has almost all of its song's names written this way. And, of course, ''Linkin'' Park itself. They originally set out to call themselves ''Lincoln'' Park, but they went for the misspelled version because it made it easier to acquire a .com domain name.
* Music/LynyrdSkynyrd, naturally.
* Then there's the American New Wave/synthpop band [[http://en.wikipedia.org/wiki/Ebn_Ozn Ebn Ozn]], whose band name was taken from each of the main band members' last names, Ned '''Liben''' (EBN) and Robert '''Rosen''' (OZN).
* [[Music/{{Eminem}} EMINƎM]].
* There's also a Scottish post-punk band named Fingerprintz who wrote and recorded songs such as "[[http://www.youtube.com/watch?v=W7BOOROoFLU&translated=1 Wet Job]]" and "[[http://www.youtube.com/watch?v=puB27JD6Hso Bulletproof Heart]]" before basically rebooting and renaming themselves into the more familiar The Silencers.
* There's also a British jazz-funk band named [[http://en.wikipedia.org/wiki/Freeez Freeez]] that had a minor hit with a song called "Southern Freeez." Curiously, like EBN OZN above, they too had their most major hit with a song titled "AEIOU," though EBN OZN's song featured spoken word lyrics and Freeez's featured falsetto vocals.
* And there's a pop/rock band that existed in the 1960s and '70s called Jaggerz, best known for their song "[[http://www.youtube.com/watch?v=-fYV3dJp-k4 The Rapper]]."
* Litefoot. U may kno him moar 4 da ''MortalKombat'' moovee n ''[[Literature/TheIndianInTheCupboard Da NDN n da Cubberd]]'' but hee iz allso a rappr. [[OverlyLongGag Eeven haz hiz pwn laybel. Itz djuzt lyke inny otha rekrd laybel tho, nkloodin skrewin hiz sined artiztz.]]
* Classic rock band Music/{{Slade}} has this in spades: "Cum On Feel The Noize" being one of the more harmless (and well-known) examples; then there are "Cuz I Luv You," "Look Wot You Dun," "Skweeze Me, Pleeze Me," "Mama Weer All Crazee Now," "Gudbuy T'Jane" ... And I'm pretty sure that somewhere in the list, there are some misspellings I missed.
** In fact, the album title ''Slayed?'' suggests that [[MyspeldRokband the band's own name might be intentionally misspelled]].
* BlaqkAudio. It's either to pronounce it as "Black" or else it sounds like "blak-k" and "Blak-k Audio" just sounds dumb.
* One of the song intros in Music/TomLehrer's live album ''Music/AnEveningWastedWithTomLehrer'' mentions an eccentric who changed his name to [=Hen3ry=] with a silent 3.
* Music/SplitEnz, although they chose that spelling as a nod to their home country of '''N'''ew '''Z'''ealand, not just because it looked cool. Also, before changing the spelling, they actually released a few early singles as Split Ends.
* [[http://www.youtube.com/watch?v=EmZvOhHF85I&t=1m28s 2 CHAINZ!!!!!!]]
* Country music group [=SHeDAISY=], complete with idiosyncratic capitalization. The name is derived from the Navajo word ''shideezhí'', meaning "my little sister".
* The Christian rock/ska band The Insyderz
* British BoyBand 5ive.
* Music/RedHotChiliPeppers' album ''Music/BloodSugarSexMagik'' spells "magic" with a "k" and all the single words as one long word.
* Music/SarahMcLachlan's "U Want Me 2"
* For a long time KMFDM gave every one of their albums a five-letter title, which led to album names like "Xtort" and "Attak."
* "[=DGTal=] Blood" by Helalyn Flowers. "Digital" pronounced with an Italian accent.
* Music/{{Covenant}}'s ''Ritual Noise'' single has a B-side titled "Xrds"(pronounced Crossroads).
* PowerPop group The Superfriendz. They probably went with that spelling to avoid confusion with {{WesternAnimation/Superfriends}}.
* Creator/EpicRecords has a division dedicated to film soundtracks called Epic Soundtrax. They initially wanted to go with the proper spelling, but were sued by musician Epic Soundtracks, who had laid claim to his StageName first.
* Country music duo Bomshel.
* There's a bluegrass group called Russell Moore and [=IIIrd=] Tyme Out. Yes, you read that right, a ''bluegrass'' group.
* Country duo Music/FloridaGeorgiaLine has an EP titled ''It'z Just What We Do''.
* Music/BigAndRich released a song called "Party Like Cowboyz" in early 2013.
* Music/TheKovenant, who were originally named Covenant until a lawsuit from [[Music/{{Covenant}} the EBM band of the same name]]; they also had to spell their name with a K to avoid conflict with another metal group named The Covenant.
* Music/TheyMightBeGiants has a song called "Mr. Xcitement", as well as one called "Mr. Klaw".
* Australian duo The Bumblebeez ([[MarketBasedTitle formerly known as]] Bumblebeez 81 in America)
* Scottish synthpop trio CHVRCHES. Although their name is pronounced "Churches," they replaced the "u" with a "v" because they wanted to show up more easily on Google Suggest.
** Replacing Us with Vs has since become their thing.
* Rapper Spaceghostpurrp and his hip hop collective Raider Klan have invented the "Raider hieroglyphics," which replaces all A's with V's all other vowels with X's (for example, "Spaceghostpurrp" becomes "SPVCXGHXZTPXRRP" and "Raider Klan" becomes "RVXDXR KLVN").
* Ferry Corsten's ''WKND''(Weekend) album.
* Music/TheKLF may stand for "Kopyright Liberation Front" or even "Kopyrite Liberation Front"; the latter would have [[ArcNumber 23]] letters.
* Music/MileyCyrus' 2013 album title ''Bangerz''.
** One of her YouTube accounts, which she opened after she had trouble posting videos on her own website, was (with some irony) called "[=MCForRealzzz=]".
** When making ''WebVideo/TheMileyAndMandyShow'', she nicknamed herself and her dancer friend/co-host Mandy Jiroux "Milez" and "Manderz" in many episodes.
** Her free 2015 album, ''Miley Cyrus And Her Dead Petz''.
* Music/SkinnyPuppy are frequent abusers, to the point where oddly spelled song titles are sort of a signature. Random examples include "Worlock," "Ambiantz," "Cullorblind," "Empte," and "Illisit."
* Music/IgorStravinsky's ''Oedipus Rex'' writes K in place of C in many words just to force the hard Classical Latin pronunciation.
* Music/AdamAndTheAnts:
** All the Ants albums have 'ADAM' written as 'AⱭAM'
** Very early in their career, mainly on singles and ''Music/DirkWearsWhiteSox'', 'ANTS' is spelled 'ANTZ'.
* Music/DelThaFunkeeHomosapien: The word "Tha" instead of "the" in his name and the word "funkee" instead of "funky".
* Music/{{Chvrches}}. Spelled that way to make it easier to Google.
* A lot of bands in the 1960s [[MyspeldRokband myspeld]] their names, often for a "psychedelic" effect from 1965-66 onward. This was arguably kickstarted by Music/TheBeatles in England in the early '60s, then by Music/TheByrds in America in 1965. The Left Banke had a big hit in 1966 with "Walk Away Renee." Then you had lesser-known bands like the Myddle Class (featuring future Music/SteelyDan member David Palmer on vocals), Kenny and the Kasuals (whose best-known song is called "Journey to Tyme"), and Zakary Thaks (who didn't have any members named Zachary...or Zakary), just to name a few.
** Subverted by Music/TheTurtles, who were briefly known as "The Tyrtles" before reverting to the conventional spelling.
* The song (and album) "Tuff Enuff" by The Fabulous Thunderbirds.
* Music/{{ABBA}} usually spells their name with the first "B" backwards.
* According to an episode of Creator/{{VH1}}'s Pop Up Video, Rockwell (of "Somebody's Watching Me" fame) initially wanted to call himself "Roqwell", but was afraid people would think he as illiterate.
* J. Cole has "Wet Dreamz", "No Role Modelz" and "Love Yourz", all three being released in a row and ending with "Z".
* {{Music/Kesha}}'s 2010 consecutive chart-topper "Tik Tok" was the biggest song of the year.
* British HairMetal band Wrathchild use this in most of their song and album titles. Examples include "Stakk Attakk," "Nukklear Rokket," "Stikky Fingerz," and "The Biz Suxx."
* German [[RuleOfCautiousEditingJudgment ...doubtful political stance...]] band "Böhse Onkelz".

[[folder:Noozpaper Komix]]
* ''ComicStrip/KrazyKat'' is one of the very first examples. She had bit parts in George Herriman's assorted Sunday comics as early as 1903, was called "Kat" by 1909, and "Krazy Kat" by 1910. By the time she got her standalone strip in 1913, she'd developed her personal dialect, a mixture of Spanish and Yiddish accents with Ks everywhere.
* Parodied in a ''ComicStrip/FoxTrot'' strip. Jason buys a gory video game called ''Mortal Karnage'' that his mother dislikes, and she lectures him on how inappropriate it is: "You're too young for this sort of thing. I mean, look at what it teaches: that human disembowelment is entertainment...that "winners" decapitate their enemies...[[ArsonMurderAndJaywalking that carnage is spelled with a 'K']]..." When he says "[[ITakeOffenseToThatLastOne I know carnage isn't spelled with a 'K'.]]", she replies, "The sad part is, that's the least of my concerns." Even funnier when you realize that at the time, his mother was a newspaper columnist.

[[folder:Nyoo Me-D-ya]]
* UsefulNotes/MicrosoftWindows NT 5.1, also known as XP, which is supposed to be short for [=eXPerience=].
* Applications written for the Linux "KDE" desktop environment tend to be named with K's replacing hard C's (Konqueror, Konsole). Sometimes the "K" usage is a tad bit more... nonsensical, as with the name of the bundled golf game, Kolf. (Admittedly, Kgolf would've looked stupid.)
** Though KDE is a project that started on Germany, and several of those words are valid German words (like Konsole).
** Originally KDE was supposed to stand for Kool Desktop Environment (currently it's simply K Desktop Environment; the K no longer stands for anything), with the Xtreme Kool Letterz spelling of "cool" being [[JustifiedTrope chosen for a good reason]], in that the commercial Common Desktop Environment (which is a proprietary (i.e. not open-source) program with more restrictive terms than KDE) already claimed the name CDE, so KDE was chosen instead to avoid lawsuits from the owners of CDE. Plus, well, "kool" is better than "common." (Eventually KDE and its rivals GNOME and Xfce went on to replace CDE on Linux and some other Unix-like systems.)
*** The aforementioned desktop environments are all based on a certain common GUI system. This system is named... [[http://en.wikipedia.org/wiki/X_Window_System X]]. Just like that.
*** It's part of a pattern. It was the successor to the W GUI system, which was used by the V operating system. No Y yet.
*** W, as in "windowed". X, being the letter after W, was a perfectly legitimate name for W's successor.
** And then there's POSIX. It stands for Portable Operating System Interface. Where does the X come from? [[RuleOfCool It looks cool]].
*** Probably from UNIX which is 'successor' of Multics (Multi-/Uni-) with an Xtreme Kool Letter at the end.
*** Ken Thompson's original version of the OS, written in Assembly, was called UNICS, a pun on MULTICS. Dennis Ritchie's C rewrite saw the name change to Unix.
** An interesting case is the music player Amarok, which was originally spelled amaroK until it was decided that looked stupid. "Amarok" is the name of a real Inuit deity, however.
* There was the Newgrounds troll group the "Kitty Krew." This sometimes lead to some unfortunate acronyms with some anti-KK groups, such as the "Kitty Krew Killers."
* The music database [[http://musicbrainz.org/ MusicBrainz]].
* it iz common 4 teenz 2 do dis when textinq, also there iz a trend of usinq q instead of g.

* Creator/SternPinball's ''Pinball/StrikerXtreme'' combines this with TotallyRadical.
* ''Pinball/BigBangBar'' has "Cosmic Dartz".
* ''Pinball/CirqusVoltaire'' has the unusual replacement of the second C in circus with a Q.
* ''Pinball/ShaqAttaq'' dares to use ATTA'''Q'''. 'nuff said.

[[folder:Pro Wreztling]]
* The [[Wrestling/MattHardy Hardy]] [[Wrestling/JeffHardy Boyz]], and their perennial Wrestling/{{WWE}} rivals Wrestling/{{The Dudley Boy|s}}z.
** The Hardy's stable with Wrestling/{{Lita}} was also referred to as Team Xtreme
** [[LampshadeHanging Spotlighted]] in a promo by Wrestling/{{Edge}} and Wrestling/{{Christian}}, the rivals of both teams, when mentioning "The Hardyz, and the Dudleyz, both of whom inexplicably spell their names with Z's"
** Edge and Christian once brought out two senior citizens dressed as the Hardys to mock them, claiming that they were the Hardy Boyz from the future. Christian asked them if, in the future, people still spell things with Z's instead of S's.
* There's NXT. Doesn't stand for anything, that's just the "xtreme kool" way of spelling "next", since the program is the "next" generation of WWE, though at least [[OlderThanTheyThink one promotion]], The Scottish Wrestling Alliance, did it beforehand.
* After many years of identifying Wrestling/WrestleMania events with Roman numerals, #17 was officially X-Seven -- pronounced "ecks-seven". And the next year saw X8, "ecks-eight". From #19 (XIX) onwards, all-Roman numbers have been back in vogue.
* Wrestling/{{ECW}}'s Rhino was renamed Wrestling/{{Rhyno}} when he went to WWF. That wasn't about being "Xtreme" though, that was so WWF/E could establish a trademark, hence why he went back to being Rhino after they canned his ass.
* ECW itself was an xception to the rulez, so to speak, by correctly using an E for Extreme. (Other wrestling promotions such as XPW are not so grammatically-minded.) It was founded in 1992, though: you can bet that 10 or so years later there would have been an X in there for sure; their late-period pay-per-view Anarchy Rulz submitted to this trope, for instance. They also started out as Eastern Championship Wrestling.
* Wrestling/ShawnMichaels and Wrestling/TripleH (and [[Wrestling/SeanWaltman X-Pac]], and Wrestling/{{Chyna}}, [[OverlyLongGag and]] Wrestling/BillyGunn [[ThoseTwoGuys and Road Dogg]] and [[Wrestling/RonKillings K Kwik]]) ARE Wrestling/DGenerationX, and they've got [[CatchPhrase two words for ya...]]
* Wrestling/VinceRusso's [[FunWithAcronyms Sports Entertainment Xtreme]] faction from the early days of Wrestling/{{TNA}}. Russo was especially fond of this. He used to pen a regular article in Magazine/WWEMagazine in the 90's where he changed any hard "S" sound to a z. For instance:
--> ''"What killz me iz that my kidz could put more heart into a match than theze guyz"''
* Towards the end of Wrestling/{{WCW}}, wrestler [[Wrestling/GlennGilbertti Disco Inferno]] started spelling his name "Disqo Inferno."
* The Radicalz PowerStable.
* NWA-TNA had a B Show in 2002 called Xplosion. In 2010, Xplosion Nacional de Lucha Libre in Chile joined the Wrestling/NationalWrestlingAlliance.

* Many radio stations especially those using a Top 40, rock, or classic hits/oldies format, although other formats have been known to use it, too will often use one of the rarely letters of the alphabet (most often, Q, X or Z, with K the next most-frequently used) along with the frequency as part of its on-air identity, such as "Q106" or "97X."[[note]]The two examples are indeed radio stations in the Quad Cities, Iowa-Illinois; Q106 is KCQQ, a classic rock station in Davenport, Iowa, while 97X is the Moline-based WXLP, also playing classic rock.[[/note]]
** Early promos for WHTZ New York (better known as "Z100") referred to "HTZ" as "the new way to spell 'hits'".
* Creator/AdamAndJoe introduced a series of Song Wars Classics, which they insisted was spelt Song Wars Kqllasixcq (with a silent X).
* Univision uses the "La Kalle" brand for many of its music stations in the U.S.
* "Kool" is also a common radio brand, used primarily on oldies stations.
* Sometimes a station's official call letters will feature a form of this. Los Angeles has a number of examples, including KROQ (pronounced "K-Rock"), KOST (pronounced "Coast"), and KIIS (pronounced "Kiss").

* Many minor league sports teams use Xtreme Kool Letterz in their names, especially indoor football teams. A few examples: Kissimmee Kreatures, Nashville Kats, Oklahoma City Yard Dawgz, Kalamazoo Xplosion, Lehigh Valley Outlawz, Kansas Koyotes, Memphis Xplorers. Baseball has the Orem Owlz, the West Tenn Diamond Jaxx, and many varieties of "Sox".
** The Orem Owlz are one of the final examples of a period of history in the state of Utah when this trope got out of hand. After people started making the connection that the three main sports teams in the state all had a double Z (The Jazz, the Grizzlies and The Buzz) people decided every team in Utah needed to follow suit. This lead to such team names as The Freezze, the Starzz, the Blitzz and the Owlz. Even The Buzz was changed to The Stingerzz for a while. This fad has since been proven to be stupid and doesn't show up with new teams.
* Another French example: LeParkour.
* The XFL lived on this trope... which is why it died after a single season.
* [[http://mywesttexas.com/articles/2009/12/13/sports/top_stories/doc4b248945ad9fb074726171.txt This high school football team.]]
** Bearkats seems to be the preferred spelling for Texas high schools using that mascot, probably inspired by the Sam Houston State University Bearkats, who adopted that name in 1923.
* Subversion: The UsefulNotes/{{Boston}} Red Sox and UsefulNotes/{{Chicago}} White Sox baseball teams didn't get their names because they looked cooler than "Red Stockings" or "White Stockings" (their original names), but because it was easier for the newspapers to print "Sox" than "Stockings." Eventually, the names stuck.
* Quebec City's minor league basketball team is known as the "Kebs," short for "Kebekwa" -- a phonetic spelling of Québécois, but rather ironically in English phonetics.
* Creator/{{ESPN}}'s Summer and Winter X-Games, originally the "Extreme Games".

[[folder:Taybletop Gamez]]
* [[OurOrcsAreDifferent Da Orkz']] FunetikAksent is spelled with these in ''TabletopGame/{{Warhammer 40000}}'', to say nothing of their species name. So are the names of lots of daemons. (Although the daemons often look like they've been spelt by randomly punching a keyboard).
** The Orks have one notable aversion- their larger tribes are ''clans'', not... [[UsefulNotes/KuKluxKlan you know...]]
* ''Waste World'' RPG presents some kool spelling variationz like "skavengers," "drakonium," "konvoys," "kimera" and the like.
* Many games, including ''TabletopGame/DungeonsAndDragons'' from 3rd edition forward, gave in and abbreviated "experience points" as "XP". This carries over to computer games, too.
* ''Dark Age'' has one character known simply as "X'cess". It's...''almost'' the correct way to spell "excess"!

* In the original Worlds of Wonder version of Lazer Tag[[note]]This specific spelling; now copyrighted by Creator/{{Hasbro}}.[[/note]], the gun was referred to as a "Starlyte".
* In ''WesternAnimation/LegendsOfChima'', the speeders are referred as "Speedorz"
* In ''Toys/NexoKnights'', the fortress is called "Fortrex"
* ''Diva Starz'', which is similar in concept to, but predates...
* ''Franchise/{{Bratz}}''
** ''Moxie Girlz'', from the same company[[note]]A SpiritualSuccessor of sorts to the above. At the time, MGA was being sued by Mattel, who claimed that the original designer of Bratz was working for Mattel at the time the Bratz toyline was being designed.[[/note]]
* ''WesternAnimation/GIJoeExtreme'', as one could expect from its name, indulges in this quite a bit. The main villain is named "Iron Klaw", one of the G.I. Joe member is "Quick Stryke", and the K in "SKAR" stands for "Kaos".

* Creator/{{Nintendo}}:
** When Nintendo introduced the UsefulNotes/NintendoEntertainmentSystem in North America and Europe, they [[CallARabbitASmeerp referred]] to its game cartridges as "Game Paks," a term which they continued using until the UsefulNotes/GameBoyAdvance.
** Two words: [[UsefulNotes/{{Nintendo 64}} Rumble Pak]]!
** Controller Pak and Expansion Pak
** System + game bundles are referred to as "paks."
* Website/GOGDotCom displays the message "Kewl, your purchase is complete" after you buy a game.
* ''Franchise/SuperMarioBros'': Bowser's vehicle in ''VideoGame/SuperMarioWorld'' was originally called the Koopa Klown Kar. For [[UnfortunateImplications obvious]] [[TheKlan reasons,]] it's spelled normally in newer games.
* The ''Franchise/MortalKombat'' series takes this to an extreme. Nearly ''every'' word which starts with a hard C (with some of the exceptions being Johnny Cage, the male Chameleon, and the live action series ''Series/MortalKombatConquest'') is spelt with a K. Worse still, those are apparently the ''proper'' spellings of those words in the MK universe. ''Damn''.
** According to pinball designer Creator/SteveRitchie (who voices Shao Kahn), he came up with "Kombat" specifically '''because''' of this trope.
--->'''Steve Ritchie:''' I made up that name and gave it to Ed Boone. They had 'Mortal' on the white board. I added the word 'Kombat'... because it was cool.
** ''VideoGame/MortalKombatX'' has a stage called "The Cove", which Boon apologized for misnaming sans the 'K' during an E3 interview (so in a sense it's the Xtreme Kool Letterz spelling for the ''MK'' universe).
* ''VideoGame/{{Gruntz}}'' is a puzzle game where plurals end in Z instead of S in the help file and in-game text. There are a few missed instances, however.
* In ''VideoGame/HauntingStarringPolterguy'' there are magic spells called "supr-scare" and "ecto-xtra" for you to pick up.
* In the ''Franchise/JakAndDaxter'' videogame series, the police {{Mooks}} are called the Krimzon Guard, despite the fact that the elites are dressed in yellow armor. (To be fair, the normal Krimzon Guard do dress in red.)
* ''Franchise/KingdomHearts'' is especially bad with this one:
** Every single member of [[TheOmniscientCouncilOfVagueness Organization XIII]] has an X in his or her name. What's more, their names are anagrams on their real names with an X thrown in for ThemeNaming. 'Roxas' is also a real name (both place and person -- it's mostly popular in the Philippines), which helped to shade the obvious anagram [[spoiler:that would ruin the TomatoInTheMirror]]. The more you know! Axel and Xion are real names as well, and the three make up the most sympathetic members of the Org.
** WordOfGod from the ''VideoGame/KingdomHeartsBirthBySleep'' [[AllThereInTheManual Ultimania]] vaguely justifies the Organization's Xtreme Kool Letteringz as being due to Xemnas's memories of his former self Xehanort's goals to [[spoiler:obtain the χ-blade.]]
*** Subversion in the above rules, as normally the foreign letters aren't pronounced any different, but here χ-blade was not pronounced as X-blade but as "chi" blade (which actually sounds more like keyblade, so it fits).
* [=HeadGames=] made a series of extreme sports games, including ''eXtreme [=PaintBrawl=]'', ''eXtreme Watersports'', and ''eXtreme Bull Riding''.
* The unofficial abbreviation usually used for the UsefulNotes/PlayStation (until the UsefulNotes/PlayStation2 came out, at least) was "[=PSX=]." This is because the console's codename during development was the "[=PlayStation=] Experimental." Made much worse by the fact that Sony actually released a separate console called the PSX (only in Japan, of course) which incorporated a video, photo, and music player with DVR support, along with the capability of playing [=PS=]/[=PS2=] games.
* This is just a screw-up of IGN's, but in a video report they referred to a [[VideoGame/SigmaHarmonics game]] as "Sigma Harmonix" in text. Ten seconds later, we have a shot of the game's logo, which spells "Harmonics" like a normal person would. (Harmonix [spelled that way] is a [[VideoGame/RockBand different brand entirely]].)
* Parodied repeatedly in ''VideoGame/KingdomOfLoathing'', especially in the [=eXtreme=] Slope zone.
* The UsefulNotes/{{XBAND}} service used a primitive modem cartridge for the SNES/Genesis to connect to players (as if on a BBS) through a now-defunct service. The company that made it went on to create a Windows-based [=MPlayer=] service, which also eventually shut down. What made it even more Xtreme was the ''A'' in the logo was upside-down. Wait for it... '''XB∀ND'''!
* Any term related to the Kremlings in ''VideoGame/DonkeyKongCountry'' has its hard "C"'s replaced with "K"'s. [[http://www.smbhq.com/users/botvgh/season7/2k1christmascarol.html This installment]] of ''BattleOfTheVideoGameHeroes'' {{lampshade|Hanging}}s this by having DK ask if they honestly have to keep doing it.
* The ''Shutokou Battle'' series of street racing games is known as ''VideoGame/TokyoXtremeRacer'' in North America.
* There's a game in the ''Franchise/{{Grandia}}'' series which is outside the main game 'continuity' (though none of the numbered games are related in any way). It's called... ''VideoGame/GrandiaXtreme''! What's so Xtreme about it? It's primarily focused around LevelGrinding.
* ''Franchise/{{Pokemon}}'': The series name outside of Japan is this. It's a shortened form of its Japanese name, Pocket Monsters, so were the trope not present, it should be Pockemon.
** The SpiritualSuccessor to ''VideoGame/PokemonColosseum'', ''Pokémon XD: Gale of Darkness''. Apparently, "XD" stands for "eXtra Dimension." The pronounciation is actually supposed to be "Excess," but really, no one says that.
** ''VideoGame/PokemonBlackAndWhite'' introduces us to Klink, Klang, and Klinklang, an animated set of living gears. There is also Krokorok and Krookodile, which are bipedal crocodile Pokemon. Averted with the first in the evolutionary line, Sandile.
* ''VideoGame/Left4Dead'' ostensibly has a reason for doing this, but it would be a blatant lie if we said the marketing team didn't use the [[Letters2Numbers 4]] in the title for this reason.
* The undeniably awesome "Petz" genre for the DS, namely the related "Dogz," "Catz" and "Horsez." How can you resist these 4 awesome names?
** Who wants to play [[http://wii.ign.com/objects/142/14254709.html Party Babyz]]!!!
** The trend started with PF Magic's original development of the Petz, Babyz, and Oddballz games. PF Magic was also responsible for ''VideoGame/{{Ballz}}''.
* Creator/TelenetJapan's ActionRPG series ''Exile'' was originally called ''XZR'' in Japan. They are pronounced the same if you torture the phonetics enough.
* The BigBad in ''VideoGame/FinalFantasyVIII'' replaces every c with a k. Although the BigBad isn't really that cool or extreme in the relative sense. That didn't stop her theme music from being ''called'' "The Extreme".
* A lot of Creator/{{Rare}}'s early games for the UsefulNotes/ZXSpectrum and UsefulNotes/{{Commodore 64}}. ''Jetpac'', ''Tranz Am'', ''Atic Atac'', ''Sabre Wulf'', ''Underwurlde'', ''Blackwyche'' and ''Dragon Skulle'', half of these could be added to YeOldeButcheredEnglish as well.
* Certain expansion packs of Koei's ''VideoGame/DynastyWarriors'' and ''VideoGame/SamuraiWarriors'' games bear the subtitle of ''Xtreme Legends''.
* The name of ''VideoGame/BattleTanx'' just says it all really, with bonus points for making it a [[WeWillUseWikiWordsInTheFuture Wiki Word]]. Also apply to one of its little-know spinoff, ''WDL: War Jetz''.
* Somewhat lampshaded in ''VideoGame/BrutalLegend'', where Eddie Riggs names his faction Ironheade, with an E to let others know that they're not kidding.
* ''VideoGame/IntelligentQube'' gets an honorable mention. It has a Q so it can be shortened to IQ. The European version goes for the more hard-hitting "Kurushi".
* [[VideoGame/GearsOfWar Marcus Fenix]], sort of. Maybe they were targeting it to a base that they knew couldn't spell "phoenix"?
* Did Blizzard think players of ''VideoGame/StarCraft'' wouldn't be able to spell "phoenix?" One of the Protoss characters is named Fenix.
** Justified. He's a Protoss, not human. Said ScaryDogmaticAliens also have names like Zeratul, Aldaris, Artanis and Raszagal[[note]]pronounced "rash-a-gall"[[/note]].
** ''VideoGame/WarCraft'' ''2'' had a good amount of this, with words like "magiks" and "berzerker" seemingly to make the universe sound more arcane and exotic. It seems Blizzard dropped this by the time ''Warcraft 3'' came around though, and they reverted back to normal spelling.
*** It's now lampshaded by Gul'dan in ''VideoGame/HeroesOfTheStorm'':
--->'''Gul'dan:''' And back then, 'daemon' had an 'a' in it, like I intended! It looks more mystical that way.
* The interface used on the [[UsefulNotes/PlayStation3 PS3]], [[UsefulNotes/PlayStationPortable PSP]], and some Sony [=TVs=] is officially named the [=XrossMediaBar=] (pronounced cross media bar).
* Some of the ''Franchise/SonicTheHedgehog'' series' music albums sometimes have the word 'Traxx' or 'Soundtrax' within its title. There's also ''[[DevelopmentHell Sonic Xtreme]]''.
* [[VideoGame/TheIdolmaster THE iDOLM@STER]]
* VideoGame/IMadeAGameWithZombiesInIt
* ''VideoGame/ComixZone''
* ''[[https://en.wikipedia.org/wiki/Dynowarz:_Destruction_of_Spondylus Dynowarz]]''
* ''VideoGame/ClockWerx''
* ''[[VideoGame/FirstEncounterAssaultRecon F.3.A.R.]]''. Usually satirically pronounced as F'three'er, Eff'three'er, or even Free'r.
* Frequently used in {{MMORPG}}s when a player really wants a name that has [[OneSteveLimit already been picked by someone else]].
* Creator/{{Jaleco}}'s ''Karnaaj Rally'' is a rather confusing variation. After a quick analyzation you've probably come to the realization that it's "Carnage Rally". It seems they changed "C" to "K", which is common ever since ''Franchise/MortalKombat''. They added an extra "A" and changed the last two letters to "J".
* ''VideoGame/AggressorsOfDarkKombat'', the title of a FightingGame for the UsefulNotes/NeoGeo, played on both ''MortalKombat'' and the name of the company that created it, ADK.
* ''VideoGame/SamuraiGunn''. Yes, two "n"s.
* The obscure 1982 Creator/{{Midway|Games}} UsefulNotes/ArcadeGame ''Kozmik Krooz'r''.
* The Turtlez in ''VideoGame/TalesOfGraces'' talk with letter Z'z replacing S'z in not just plural wordz, but also random wordz.
* ''VideoGame/RockmanXover'''s title (pronounced "crossover").
* ''Streemerz'' from ''VideoGame/Action52''
* ''Loopz''
* ''VideoGame/{{Xexyz}}''
* The UsefulNotes/GameBoyColor versions of ''VideoGame/MegaManX'' were titled ''Mega Man Xtreme''.
* ''Skeleton Krew'' goes a bit krazy with K's.
* ''[=EZ2DJ=]'', apart from the title itself, has a judgement called "COOL"...followed by a higher judgement called "'''K'''OOL".
* ''VideoGame/CrimzonClover''
* In the ''[[Videogame/{{X}} X-Universe]]'' series, the highest Combat rank and the highest Trading rank are both called X-TREME - both of which require you to [[NGOSuperPower slaughter tens of thousands of capital ships or utterly dominate the economy]], respectively. There's also the expansion pack for the first game, called ''[[PunBasedTitle X:Tension]]''. The signature ship of the [[Videogame/XBeyondTheFrontier first game]] (which can be [[ContinuityNod re-acquired]] in ''X3: Terran Conflict'') is called the ''Xperimental Shuttle''. In the ''Xtended Terran Conflict'' GameMod, there's also the "[[HarderThanHard XTREME]]" difficulty setting.
* ''VideoGame/DynamiteDux''
* The entire [[FourX 4X]] game genre. eXplore, eXploit, eXpand, eXterminate!
* ''Videogame/CounterStrike'' 1.6 has the Terrorist faction ''[[Main/LeetLingo L337 Krew.]]''
* ''VideoGame/{{Qix}}''. (Proof that it's this trope: The Sparx.)
* ''[=DethKarz=]'', a futuristic racing game.
* ''Shuuz'', a horseshoe-pitching UsefulNotes/ArcadeGame.
* The VideoGame/JustDance series has a song called "Chiwawa" [[note]]As in "chihuahua", the dog breed.[[/note]].
* ''[[VideoGame/{{DJMAX}} SUPERBEAT XONiC]]''
* ''VideoGame/DragonballFighterz''. Contrary to its stylization and the pronunciation of ''Anime/DragonBallZ'', it is simply pronounced "''Dragon Ball Fighters''", making it this trope.
* Pictured above, a recurring joke in the ''VideoGame/ClubPenguin'' comics was a penguin who created X-Treme versions of the games by adding jet packs.
* ''VideoGame/MoshiMonsters'':
** One shop is called Dodgy Dealz. Another is Katsuma Klothes.
** There's a cereal called Katsuma Krunch.
* The online flash game creator Website/{{Sploder}} has a power-up called the Power Gluv.
* ''VideoGame/{{Oddworld}}'': The hick chicken folk encountered in ''Stranger's Wrath'' are called Clakkerz.
* ''VideoGame/SimTunes'': The little musical insects in the game are called Bugz.
* ''Franchise/SpyroTheDragon'': Spyro's dragonfly sidekick is named Sparx.

[[folder:Vizual Novelz]]
* In ''VisualNovel/UminekoWhenTheyCry'', Furudo Erika is an example of this in Japanese. Her given name, which would usually be written エリカ in [[UsefulNotes/JapaneseWritingSystem katakana]], instead has the archaic spelling ヱリカ. Fitting for a MarySue {{Deconstruction}}.

[[folder:Web Anym@tion]]
* Parodied on ''WebAnimation/HomestarRunner'': the creators have intentionally used Xtreme Kool Letterz in ways that make no sense:
** Spelling "awesome" as "awexome."
** The best is "[[http://www.homestarrunner.com/sbemail191.html Videlectrix Kidx]]."
** For AprilFoolsDay, they make an intro for [[DarkerAndEdgier HSR Xeriouxly Forxe]]. Homestar... er, "H. Star" pronounces this with each X as a "KS" sound, rexulting in him getting xcolded by "S. Bad," who replaxes ''all'' hix xibilant conxonantx with pronounxed X's.
* ''WebAnimation/DSBTInsaniT'': The title of the series itself, which uses [='insaniT'=] instead of 'insanity'

[[folder:Web Komix]]
* ''Webcomic/PennyArcade'''s Tycho [[http://www.penny-arcade.com/comic/2008/02/04 has a fit]] when he hears about "Gamez N Flix."
* In a similar fashion, Erin from ''Webcomic/CriticalMiss'' has an "[[http://www.escapistmagazine.com/articles/view/comics/critical-miss/7665-Critical-Miss-7 English gland]]" that flares up that flares when the language is abused, and becomes an EldritchAbomination when she sees too much of this.
* ''Webcomic/KhaosKomix''. It fit the original comic a bit better than the current incarnation.
* ''Webcomic/{{xkcd}}'': The apparent acronym has no particular meaning, but hits a few kool letterz. According to the author: "It's just a word with no phonetic pronunciation -- a treasured and carefully-guarded point in the space of four-character strings."
** {{Discussed|Trope}} with car model names in [[http://xkcd.com/1571/ this comic]]. The author offers a few... [[UnfortunateNames suggestions]] (Lincoln [[{{UsefulNotes/Socialism}} Marxism]], anyone?) that nevertheless score high on this rubric.
* In ''Start of Darkness'', a print addendum to the popular webcomic ''Webcomic/TheOrderOfTheStick'', Xykon's main goal while he was alive was to be a "badass evil villain". To this end, he not only invents a "cool-sounding name with an 'X' in it" for himself, he [[SpellMyNameWithAnS splits hairs over how people spell it]].
-->'''Xykon:''' ... and my name is Xykon.\\
'''Right-Eye:''' Um, yes, OK, great and powerful sorcerer Zykon--\\
'''Xykon:''' No, no, no! With an X, not a Z! Z's are for pussies.
* A.I. in ''Webcomic/SchlockMercenary'' sometimes use numbers to substitute for letters, and even whole syllables, in their names; for example, "5er0" (pronounced "Ver-None," with 5 substituting for its Roman equivalent, V) instead of Vernon.
* ''Webcomic/LastRes0rt'' has it right in the title, though WordOfGod justifies it on the basis of having a hard time securing a domain name in the "correct" spelling.
* [[http://overcompensating.com/posts/20100126.html Parodied]] in ''WebComic/{{Overcompensating}}''.
* The title ''Webcomic/{{Loserz}}'' has to be a bit sarcastic about this.
* ''[[http://theslackerz.com/ Slackerz]]'', (even in the title) alludes to this constantly.
* And there's "Mylytant Femynyst" from ''Webcomic/{{Precocious}}'', for the "wymyn" version (see below).
* The trolls of ''Webcomic/{{Homestuck}}'', who seem to be in a LensmanArmsRace for the most obnoxious IM behavior, among other things pathologically replace letters with Xtra Kool ones, or with numbers.
** An update gave us the most literal example of this trope with [[spoiler:Latula Pyrope]].
* Dan of ''Webcomic/ElGoonishShive'' sometimes uses these in the narration boxes.
* Duzz talks like this in ''Webcomic/LuminaryChildren''.

[[folder: Web Ureejnul]]
* [[WebOriginal/LOLCats I can haz cheezburger?]]
* Meez was guilty of this, though it has improved over the years. It would lead to a lot of {{Narm}}.
-->"You have received an infraction for violating the Meez Rulz."
* Parodied in the WebAnimation/HomestarRunner toon [[http://www.homestarrunner.com/aprilfool10.html "Xeriouxly Forxe"]], which itself was referenced by [[http://www.homestarrunner.com/main26.html main page number 26]].
* From ''Website/TheOnion'': "[[https://www.theonion.com/alphabet-updated-with-15-exciting-new-replacement-lette-1819571356 Alphabet Updated With 15 Exciting New Replacement Letters]]"
* ''WebVideo/AtopTheFourthWall'' has a running gag whenever someone uses this (or other bad grammar) where an echoey version of Linkara's voice appears along with the text "Because Poor Literacy is ''Kewl.''" Later episodes have him swapping out "kewl" for another word or phrase. Elsewhere, he'll use some variation of this phrase to denote [[RougeAnglesOfSatin mistakes that could have been proofread out]].
* WebVideo/{{Brutalmoose}} discusses this in his review of ''Razor Freestyle Scooter'': "The next level is called 'Schoolz Out'...with a z. Because, y'know, z is the hippest letter of the alphabet. It's what all the kids are into."
* Qrow from ''WebAnimation/{{RWBY}}''. Everything about him has a major crow motif but with qooler spelling.

[[folder:Westurn Anym@tion]]
* ''WesternAnimation/ThePowerpuffGirls'': In "Knock It Off," Professor Dick Hardly is selling his PPG clones under the name "Powerpuff Girlz X-treme," even going as far as calling Chemical X "Chemical X-treme."
* ''WesternAnimation/FostersHomeForImaginaryFriends'' gives us Jamez Withazee. Get it?
* ''WesternAnimation/CloneHigh'' parodied this with a TotallyRadical energy drink called X-Stream Blu.
* Presumably, the reason ''WesternAnimation/SWATKats'' isn't titled ''SWAT Cats'' is because of this trope. The fact that the subtitle is "The Radical Squadron" seems to support that (as does the whole series' tone).
* Following the "Keystone Kops" example above, an episode of ''WesternAnimation/TheSimpsons'' has Krusty the Clown (which is an example right there) hosting "Krusty's Komedy Klassic" at the Apollo Theater. He ''really'' shouldn't have put the [[FunWithAcronyms acronym]] on stage in big white letters in front of ''that'' many black people...
-->'''Krusty:''' Hey, hey! It's great to be back at the Apollo Theater, and... ''(notices the three white K's behind him onstage)'' [[UnfortunateImplications KKK?]] ''That's'' not good!
* Also related to the above example, ''WesternAnimation/SpongeBobSquarePants'''s principle restaurant is titled the Krusty Krab.
* Another early example of this trope being applied deliberately: ''WesternAnimation/DragonFlyz'' (from 1996).
* "Sonic Sez" from ''WesternAnimation/AdventuresOfSonicTheHedgehog''. Of note, though, is the fact that "Sez" was written by Tails in each case, and when Sonic appeared, he would correct it to "Says". "Sez" was also used on newspaper headlines [[OlderThanTheyThink decades]] before ''[=AoStH=]'' came about.
* ''WesternAnimation/XMenEvolution'' has [[TheScrappy Spyke]] and [[AscendedExtra Berzerker]].
* ''WesternAnimation/GalactikFootball''
* In ''WesternAnimation/BatmanBeyond'''s future, the streets of Gotham City are plagued by a gang called the "Jokerz." Bruce is not impressed.
* ''WesternAnimation/CodeLyoko'' does this with the monsters: Kankrelat (from French "cancrelat"), Blok, Krabe, Kongre, Rekin, Kalamar, Kolossus... Justified in-story with Odd doing most of the naming, and that's just the kind of thing he'd do. On the same note: "[[CallingYourAttacks Lazer Arrow!]]"
* The world of ''WesternAnimation/InvaderZim'' has no school, but rather a "Skool." Although it's not there to be cool, just to show how [[CrapsackWorld crappy their world is.]]
* Disney had also originally intended to use that spelling of the word for the title of ''WesternAnimation/TheEmperorsNewSchool''. They also have the main character '''K'''uzco, whose name came from the Peruvian city '''C'''uzco.
* The ''[[http://www.imdb.com/title/tt0482151/ X-DuckX]]'' play this totally straight.
* ''WesternAnimation/{{Futurama}}'':
** In the year 3000, occurrences of "sk" have been replaced by "x". You can frequently hear characters saying "Can I ax you a question?"
** One episode {{lampshade|Hanging}}s this while {{playing with|ATrope}} BlackmailIsSuchAnUglyWord.
-->'''Bender:''' Blackmail is such an ugly word. I prefer "extortion." The "x" makes it sound cool.
* Though it's not really in the cartoons themselves, these fan-made profiles for [[http://users.cwnet.com/xephyr/rich/dzone/hoozoo/simba.html Simba]] and [[http://users.cwnet.com/xephyr/rich/dzone/hoozoo/timon.html Timon & Pumbaa]] spell ''Disney/TheLionKing'''s villain's name as "Skar", despite it being spelled as "Scar" everywhere else.
* Ellipsanime's ''WesternAnimation/{{Xcalibur}}'' drops the E from the name of a certain legendary sword to supposedly sound cool.
* ''WesternAnimation/{{Wakfu}}'' makes largely use of SdrawkcabName, but sometimes combines it with this for some names, like "Rubilax" ([Exc]alibur again), "Kabrok" ("corbac", French slang for raven), "Sybannak" (Cannabis)...
* ''WesternAnimation/TheAmazingSpiez'', a spin-off series of ''WesternAnimation/TotallySpies''
* Two episodes of ''WesternAnimation/JimmyTwoShoes'': "No Rulez Rules Jimmy" and "Team X-treme Team."
* The title character from ''WesternAnimation/TheLegendOfKorra''. At first, the creators could not find a name for her, but when they were staying in an eco-lodge, the owner introduced them to his dog "Cora". They agreed on the name and changed it to "Korra", most likely to fit into the Water Tribe's tradition of having "K" somewhere in their name, so this trope might be a coincidence.
* WesternAnimation/{{Ratz}}
* [[LampshadeHanging Lampshaded]] in the ''WesternAnimation/RobotChicken'' sketch "[[Film/EightMile 8]] [[WesternAnimation/LooneyTunes Carrot]]".
-->'''[[WesternAnimation/DaffyDuck Daffy]]:''' B-Rabbit, you're on.\\
'''WesternAnimation/{{Bugs|Bunny}}:''' Eh, I told you, Daffy, my name is Bugs.\\
'''Daffy:''' No, your MC name is B-Rabbit! [[WeAreStillRelevantDammit We've got to appeal to today's kids!]] [[TotallyRadical No longer Looney Tunes, we're "Lizooney Tizunes"! Woo-hoo! Real hip-hop, dawg!]]
* ''WesternAnimation/CourageTheCowardlyDog'' has [[strike:Cats]] Katz.
* ''WesternAnimation/TheProblemSolverz'' and many of its episode titles. Interestingly, "Zoo Cops" is an exception to this. And bizarrely enough, Problem Solvers is actually spelled correctly in the pilot (just not in the title).
* ''Animation/CubixRobotsForEveryone''. Standard robots will have 'ix' on the end of their names, while Doctor K's creations always have a name beginning with K. Kolossal, Krab, Katastrophe, Klobber, Kannon, [[spoiler:the Kulminator]]...
* A short-lived SaturdayMorningCartoon on Creator/{{CBS}} in 1998 was called ''WesternAnimation/{{Birdz}}''.
* In ''WesternAnimation/{{Daria}}'': Mystik Spiral, Trent Lane's band. Though he might change the name....
* The third season of ''Literature/{{Franklin}} and Friends'' has Aunt T.'s Karate Klub.
* There's also Klondike Kat, which was produced by Total Television (the makers of [[WesternAnimation/KingLeonardoAndHisShortSubjects King Leonardo]], [[WesternAnimation/TennesseeTuxedoAndHisTales Tennessee Tuxedo]], and WesternAnimation/{{Underdog}})
* ''WesternAnimation/{{Birdz}}''
* In the second Disney episode of ''WesternAnimation/{{Doug}}'', Doug's new school is having a contest to see who can come up with a name. One of Skeeter's suggestions is "Kool Skool". He then has to point out he spelled it wrong on purpose.

[[folder:Reel Lyfe]]
* American English favors using a Z, instead of an S that sounds like a Z, in various words, including "recognize" and "analyze." This follows the general trend for American English to favor more symplified and phonetic spellings even when it messes with the etymology. However, 'recognize' (though not 'analyze') is a permissible spelling in British English, and is in fact closer to etymology: Latin 'izare', Ancient Greek 'izo, izein'. Spelling analyse with a Z is further from etymology, however; it is not '*anal' + 'ize' with an odd spelling shift, but a derivation of 'analysis'. The Z in '-ize' and 'lyse' does not simplify spelling, because the regular spelling for these words ending in similar sounds is S, and so a Z is aberrant. (This is not to say American spellings do not mess around with etymology, but only a few do: 'ae' and 'oe'/'e', for example.)
** Inspector Morse once used this as a plot point; Morse noted that if someone were truly Oxford-educated as he claimed he would know his Greek roots well enough to spell "realize" with a "z", not with an "s".
* ''America's Best Dance Crew'' is a particularly JustForFun/{{egregious}} example of this. Almost every crew have "kool letterz" their name, but as an example three crews have the word "crew" in their name. Here are the ways they spell that otherwise simple word: "Cru," "Kru," and "[=Cr3w=]."
* For the same thing with different causes, see the [[https://en.wikipedia.org/wiki/Womyn womyn]]'s movement and [[https://en.wikipedia.org/wiki/Asian_pride AZN pride]].
* Many of the baby names discussed at [[http://www.notwithoutmyhandbag.com/babynames/index.html this page]] suffer from this. "Mackenzie" not unique and special enough? How about Makenzy? Mykynzy? Mkynzptlk.? [[Characters/SupermanRoguesGalleryMToZ Mxyzptlk]]?
* When parents name their children with Xtreme Kool Letterz:
** Common both in Brazil and in Hispanic countries around the Caribbean: many mothers (specially from poor families) like to put fancy, Xtremely Kool names on their children. From simply replacing 'c' with 'k' to entire contraptions with loads and loads of 'k', 'w', 'y', 'll' etc...
** The tendency in Hispanic countries to uses names with a 'Y' somewhere, usually substituting 'J' if at the beginning of the name, and 'I' or the 'LL' sound if in the middle or at the end. The fad was so bad in Caribbean countries in general that Cuban dissident blogger Yoani Sanchez named her blog "Generación Y (Generation Y)", not only as a pun on "Generation X", but to point out the whole generation of people born from TheSeventies to TheNineties saddled which such kind of names.
** This is also common as hell in Black America. Those "Stereotypical {{ghetto baby name}}s" are that way because it's popular. "Shaniqua" and "Keyshana" etc etc. [[http://www.youtube.com/watch?v=pCdmiZyyGjQ link]]
** Filipino families today are guilty of naming their children with such names as Krizalyn and Johndex. And their names are written on their ''birth certificates''. Their excuse is that the old Filipino names [taken from Spanish names] are a tad boring and the recent American names are quite becoming cliche, so they decided that it would be cool if they add an extra letter and change some letter.
* The AHEM [[PrivateMilitaryContractors military contracting company]] formerly known as Blackwater has changed their name to Xe. One could say that these days, Blackwater's name is mud.... So they changed it. Plus, there is the irony of them changing their name to the chemical symbol of an almost inert gas. [[Creator/{{MSNBC}} Rachel Maddow]] quickly took to pronouncing it "she."
** In a further attempt to reinvent their PR image and distance themselves from their notoriety, Xe is now known as "Academi," which still hits this trope pretty hard.
* There is a cable TV channel in Brazil (Telecine) that once a week broadcasts movies subtitled with internet slang and Xtreme Kool Letterz.
* A possible etymology for "OK" is that it was an Xtreme Kool Letterz version for "All Correct": "Oll Korrect".
** More likely it was shorthand for Zero Killed.
** There was a short-lived fad for these abbreviations around 1840, such as "KG" = "(K)no Go". OK seems to be the only one that caught on and lasted, at least partly because of its association with UsefulNotes/MartinVanBuren--his campaign actively linked the abbreviation with his nickname, "Old Kinderhook" (Kinderhook being his hometown in Upstate New York).
* The UsefulNotes/KuKluxKlan is clearly an example of this, and they have a potential to ruin an otherwise appealing use of Xtreme Kool Letterz when someone notices that the initials are KKK. Sometimes in comedy, as with ''Krusty's Komedy Klassic'' in ''WesternAnimation/TheSimpsons'' or the Kappa Kappa Kappa sorority on ''Series/{{MADtv}}'', this unfortunate set of initials will be played for laughs. Remember, though, that HitlerAteSugar and this trope is still [[TropesAreTools not a bad thing]] even though a group of equally repulsive racists has taken a liking to the use of Xtreme Kool Letterz.
** In the 20s, a Klansman could meet at a Klavern to have a Klonversation with the local Kleagle. Don't know the rules? Don't worry, they're all laid out in the Kloran. (Apparently, the Klan had the same naming conventions as the ''VideoGame/DonkeyKongCountry'' series.)
** There's an urban legend that "Ku Klux" approximates the sound of a shotgun being cocked. Another idea was that "Ku Klux" is a bastardization of ''kuklos'', Greek for "ring" or "circle". The Kuklos Adelphon was basically the KKK before it was the KKK. Rumor has it that "klan" was added to the end, because the founders of the KKK were Scots-Irish.
** There are various theories (some with more credibility than others) about the origin of the name, but no one knows the true story. All of them, however, contain a tacit admission of "it was mostly done that way because it looked cool." Whatever the reason, it gave an unhelpfully tongue-twisting name that many people erroneously or accidentally render as ''Klu'' Klux Klan.
* For trademark purposes, the Sci-Fi channel changed its name to [[http://io9.com/5170447/sci-fi-channel-changes-its-name-to-a-typo "Syfy"]], which is Polish for "acne", and just happens to be (plural) short for syphilis. Parts of the sci-fi fanbase ran along with it. (No doubt you saw the subtle irony in the Polish translation.)
* In the UsefulNotes/JapaneseWritingSystem:
** Using katakana in places where hiragana or kanji is normally used is something of an equivalent of Xtreme Kool Letterz. For example, オ早ウゴザイマス is considered more Xtreme than お早うございます. This is OlderThanTheyThink: in medieval Japan, hiragana was considered an effeminate script, and many male writers used katakana instead. (Usually, when a character's lines are written in katakana, it's done to indicate that the character is speaking in a thick foreign accent or with NoIndoorVoice. Katakana is normally used for loanwords originating in non-Japanese countries, especially English.)
** There's also the inverse, writing foreign words in hiragana instead of katakana (example: "start" as "すた〜と" instead of "スタート").
** Currently, it is considered 'kewl' to render foreign-originating words in Kanji for phonetic value ("[[http://en.wikipedia.org/wiki/Ateji Ateji]]", it's called; VideoGame/{{Touhou}} uses a lot of these, incidentally).
** Using the archaic katakana ''wi'' (ヰ), ''wo'' (ヲ) and ''we'' (ヱ) as substitutes for ''i'' (イ), ''o'' (オ) and ''e'' (エ), which are pronounced exactly the same, in words such as "{{otaku}}". The 1946 reform of the Japanese language eliminated the use of ''wo'' within words, and abolished ''we'' and ''wi'' entirely.
* The research paper database arXiv (the X is a Greek chi). Its pronounced "archive."
* Aleister Crowley popularized the "Magick" spelling for magic [[OlderThanTelevision in the modern western world]]. Now, there are people who spell it "majyyk."[[note]]Fun fact: dropping needless 'k's at the end of words like "magick," "musick" and "publick" was one specific goal of folks like Noah Webster.[[/note]]
* All X-perimental aircrafts by the USAF, from the Bell X-1 to the Boeing X-53 are called [[http://en.wikipedia.org/wiki/X-plane_(aircraft) X-planes]].
* The Old English/Old Norse letter ''thorn'' (Þ / þ) has been used in place of a p in the "tongue sticking out" emoticon. Conversely the ð in Skaði (pronounced like the th in thus) has been turned into a d among astronomers.
* In the UK at least, it is common to give limited-stop bus routes a number with an "X" prefix for Express, although this goes back many years. Of cource whilst giving a bus route an "X" prefix doesn't make it sound cooler (try as they do, making buses "cool" is very hard), it does make it sound ''faster''. It is not uncommon to find "X" routes that are far from express.
* Kamaz. It is actually an abbreviation, standing for ''Kamsky Avtomobilny Zavod'', or "Kama Automobile Plant" (Kama is the name of a river).
* The '50s and early '60s hot rod culture favored the term "kustom", particularly in George Barris' Kustom Kars (Barris is famous for many awesome TV Kars, including Series/TheMunsters' family koach, the [[Series/TheMonkees Monkeemobile]], the [[Series/TheDukesOfHazzard General Lee]] and the [[Series/{{Batman}} Batmobile]]).
* In 11 markets, Comcast has changed the name of its "Triple Play" service to [[http://www.xfinity.com/home/ Xfinity]], probably under the belief that it is "contemporary." Furthering this delusion, they have covered the site with Klavika (a [[UsefulNotes/{{Fonts}} sans-serif typeface]] with squarish curves that has become a go-to "web 2.0" face). Their mobile Internet service, meanwhile, is the predictably "kewl" ''Internet 2go''.
* The Monster Raving Loony Party has purposely misspelled "Education" in their suggestions (2) page for their manifesto.
* Toys "Я" Us. In this case, it owes more to the idea that kids sometimes write letters backwards when they're very young and just learning to write.
* Native Instruments seem not to be able to decide between Xtreme Kool Letterz and GratuitousGerman. Product names like Reaktor or Kontakt fall into both categories, Komplete falls only into the former, and Maschine falls only into the latter.
* Roland's top workstation generations of the 21st century have been named Fantom. The true reason, however, is that they weren't allowed to use Phantom.
* The Oberheim Xpander synthesizer.
* Wichita Falls, Texas has a mall called Sikes Senter.
* The Improv Comedy troupe known as [[http://comedysportz.com/ Comedy Sportz]].
* The computer hardware manufacturer Asus has a range of "Xtreme Design" motherboards.
* "Tyre". Sure, it's the legitimate British and Commonwealth spelling of the word (for "the rubber thing you put on a wheel" -- as distinct from "to weary", which remains ''tire''), but it sure rubs off this way to North Americans.
** Ditto for "kerb" and "gaol".
* An Android OS Twitter Client was renamed Twidroyd from Twidroid after being bought by Idealab's TweetUp. The reasoning for this is that Lucas Films owns the trademark for the word Droid, nevermind the other bamillion apps with Droid in the name that aren't being sued right now.
* In U.S. Air Force Civil Engineering units, pavement and heavy equipment operators are also known as "Dirt Boyz."
* In the Philippines, there is a language called jejemon which follows the rules of this trope. And yes, the Filipino {{grammar nazi}}s hate them.
* Raven-Symoné. The accent serves no obvious purpose, since it's pronounced "Raven-Simone".
* Phreaking, a now-discredited trope. (When was the last time you saw a phone booth?) Also, fone cards.
* Coca-Cola had Coke Blak, with the a having what was supposed to be a breve but looked more like a tilde. It was a mixture of Coke and coffee.
* Many Christian youth-oriented church groups have been doing variants on this since the late 80's and like most, it's questionable if there's any payoff for doing it.
* The Cité Internationale Universitaire in Paris, which houses international students at the various Paris learning institutions, has a lot of fun with foreign letters on its signs, [[http://farm5.static.flickr.com/4001/4548338390_703ca13892.jpg such as this]] or [[http://www.decitre.fr/gi/31/9782858938131FS.gif this]]. They don't even stay consistent throughout.
* There's an office building in the St. Louis suburbs called Cequel III.
* Xian and Xmas are common abbreviations for Christian and Christmas. The X abbreviation is taken from the Greek letter X or Chi, the initial of Christ.
* Behold...the [[http://jalopnik.com/5882944/chevy-cruze-wagon-fords-c+suite-shuffle-and-amg-aint-going-diesel Chevrolet Cruze Wagon]]!
* The Citroën Xsara. Pronounced "Zara" in UK adverts.
* The [[CoolCar AMC AMX]]. Its full name is the American Motors Corporation [[DepartmentOfRedundancyDepartment American Motors]] eXperimental
* Car and motorcycle manufacturers in general are very fond of the letter {{X|MakesAnythingCool}}, as it can be associated with sportiness, technology and luxury.
* The names kids choose for themselves on UsefulNotes/XboxLiveArcade. Hell, even the name ''UsefulNotes/XBox'' itself.
* The now defunct Burger Chef chain, which was sold to Hardee's, had sandwiches named the Super Shef and the Top Shef (a burger with cheese and bacon).
* As mentioned above in Sportz, there was a ''ZZ'' naming fad in Utah in the 1990s. Another surviving [[ArtifactTitle artifact]] of that era is one Salt Lake City suburb's community festival: Taylorsville Dayzz.
* [[http://www.sheetz.com/main/ Sheetz]] a Mid-Atlantic convenience store chain replaces the plural S with a Z for many of their [[http://www.sheetz.com/main/food/menu.cfm menu items]] EX: Saladz & Wrapz. As well as including the letters SH. EX: Shmuffin or Shwings.
* A once-popular fad that might have receded by now was making cubes ("squares") out of flavored gelatin. When Knox-brand gelatin was used, the cubes were affectionately called "Knox blox."
* Some Blood and Crip sets change spellings of words to fit their gang mentality. Bloods will replace "C" with "CK" meaning Crip Killer wherever applicable (or replace it with a B, as in the phrase "bickin back being bool.") Alternatively, Crips will replace any "CK" with a "C", and would write "kick back" as "kicc bacc."
* Tastee-Freez, an American ice cream chain.
* Also Karmelkorn, a mall-based popcorn vendor. Once popular in malls through the 1970s, it's now down to about 25 locations, almost all of which are co-branded with Dairy Queen and/or Orange Julius.
* Donut vendor Krispy Kreme.
* The Spanish language has the "hoygan" 'dialect' for those people who don't give a flying rat's ass about spelling. The rules involve adding or removing random "h"'s anywhere (since it's a silent letter, you can put as many as you want and not notice a thing in the final pronunciation!), and switching "b" and "v" around (same pronunciation), "y" and "i" or "y" and "ll" (depending on the sound); "qu", "c" and "k"; "g" and "j"; and "z", "c" and "s" as much as you want. And, of course, no accents whatsoever. So "Hoy es un buen día" would become "oi ez un vuen dya". Enjoy the eyebleed.
* Philadelphia snack cake company "Tastykake."
* The Great Northern Railway [[http://en.wikipedia.org/wiki/GNR_Class_C1_%28small_boiler%29 Klondyke]]-class locomotive of 1897 , named for the Klondike gold rush that happened that same year. Both spellings had equal currency on the GNR.
* Kampgrounds of America (KOA), an American campground franchise.
* The word "laser" is often misspelled "lazer" despite being an acronym.[[note]]Light Amplified by Stimulated Emission of Radiation[[/note]]
* ''WesternAnimation/{{Futurama}}'' writer/producer David X. Cohen, whose middle name is actually Samuel. There was already a writer credited as David S. Cohen in the Writers Guild of America and members are not allowed to have the same name, so he changed his middle initial to X because it "sounded sci-fi-ish" and he thought it would make him "the David Cohen people would remember".
* In the early 90s, a cooking-ware company *very* briefly applied this to one of their product lines, resulting in "Kook's Klub".
* There was once a restaurant named Goombazz Big City Eatzz, most known for being the subject of an episode of ''Series/RestaurantImpossible''. As the owner was an old man with a technophobic streak, the edginess was unintentional: When host Robert Irvine asked him about the spelling, he said that the double Z's come from the word "pizza."
* UsefulNotes/SpaceX, a.k.a. Space eXploration Technologies Corporation. Elon Musk's other company, Tesla, has a car called the "Model X" despite having only three different models (the model numbers spell [[GettingCrapPastTheRadar "S3X"]]).
* Some fan conventions use a "K" instead of a "C" for "Con" (short for "convention"). Notable examples include A-Kon in Dallas and Otakon in Washington DC.
