->''"But woe to the Earth and Sea, because the Devil has gone down to you! He is filled with fury, because he knows that his time is short...Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is Six hundred sixty six."''
-->-- '''Literature/BookOfRevelation''' 12:12, 13:18 New International Version.

You know what this is. Six hundred and sixty six, the NumberOfTheBeast, first mentioned in the ''Literature/BookOfRevelation'' in Literature/TheBible, making this OlderThanFeudalism. Sometimes used for that extra symbolism everyone loves, but it's usually used because it's [[RuleOfCool a nifty keen]] way to show that [[MarkOfTheBeast something is eeeevil]].

Oddly enough, the Beast of Revelation itself [[OneSceneWonder is rarely ever mentioned]] anymore. (In fact, there were two of them in the Book of Revelation, the Number describing the second.) The Number has totally eclipsed the being it represented.

Sometimes gets truncated to 66 or lengthened to 6666 (or even beyond) if 666 is too high or too low a number, yet still evokes the NumerologicalMotif. Or if you're dealing with LouisCypher, 666 may be part of his address or phone number, in the vein of FiveFiveFive. Another common gag is for this to overlap with SixIsNine, having someone ineptly render the Beast's number as 999.

The actual number, however, is a subject of debate among theologians and historians: many say the number is actually 616, as some of the older Latin copies of Revelation list it as that rather than 666; all the Greek ones list it as 666, and most probably the name it indicated had a different sum according to their numerological schemes in different alphabets. However, 666 is so much better known that if you try to go with 616 instead it will likely [[ViewersAreGeniuses fly over the heads of most readers and viewers]]. Note that either way, it is the value six hundred and sixty six or six hundred and sixteen, not just three sixes in a row (like June 6th 2006). In fact, back then it would have been written χξϛ/χιϛ (chi - xi - sigma / chi - iota - sigma)[[note]]The Greeks used a unique set of symbols for each decimal place. So χξϛ would be (600)(60)(6) and χιϛ would be (600)(10)(6)[[/note]] in Greek and the guy who wrote ''Revelation'' would totally not get the stuff about three sixes in a row.

Interestingly enough, another interpretation is 216, as some older translations define this enigmatic number as "6 by 6 by 6", or 6[[superscript:3]].

The "616" is also the number given to the main Franchise/MarvelUniverse (as opposed to the other alternate realities).

In Mandarin UsefulNotes/{{Chinese|Language}}, 666 sounds like the phrase that roughly translates as "everything going smoothly", so the number is considered lucky in China especially for commercial undertakings.

If you're looking for the SignatureSong of Music/IronMaiden which has the same name, see their Trope page.

Compare with its Asian counterparts, OneHundredAndEight and [[FourIsDeath 4]]. For the Creator/RobertAHeinlein novel, see ''Literature/TheNumberOfTheBeast''. Not to be confused with [[FiveFiveFive 555]], which is about fake phone numbers, though as stated above, sometimes an evil-associated fake number can make them overlap. See also MarkOfTheBeast, when association with dark powers gives someone a physical marking.



[[folder:Anime & Manga]]
* The [[ArtifactOfDoom Book of Darkness]] in ''Anime/MagicalGirlLyricalNanohaAs'' has 666 pages. The last Mistress of it, Hayate Yagami is also associated with the number 6, who has [[GoodWingsEvilWings seraph wings]] and was born in June. Six years after the Book of Darkness Incident, she decides to found her own section to investigate the Relic incidents, four years later she achieves her goal by founding the Riot Force 6. Six years after the JS Incident, she founds another section, Special Duty Section 6. The Yagami family has six members, Hayate herself, the four Wolkenritter and Reinforce Eins/Zwei. They adopt later a seventh member, Agito; but this can be interpreted as Hayate having six children now.
* ''Anime/NeonGenesisEvangelion''
** In ''The End of Evangelion'', Ritsuko uses program 666 to protect NERV from being hacked by SEELE.
*** There's also a parking lot bay number 666, however we only see the number of the bay next to it: 665. In the DVDCommentary they joke that it's the "Neighbour of the Beast".
** ''Anime/RebuildOfEvangelion'': Mari Illustrious Makinami [[spoiler:hijacks Unit-2 in order to fight the last Angel in You Can (Not) Advance, she activates the Eva's Berserker mode with Code: 666, named, you guessed it, The Beast]].
** Ironically, the new version of [[http://www.youtube.com/watch?v=V2N8woYX7io The Beast]] has the vocals (rather, vocal, as it's only one word) of ''Hallelujah''...which, given the use of Handel's [[CrowningMusicOfAwesome Messiah Chorus]] in the original continuity, [[MindRape caused many fans to freak out]].
* In the original ''Anime/YuGiOh'' episode "Evil Spirit of the Ring" (the first appearance of Dark Bakura in the anime(we see a card Bakura's {{Flashback}} where his father got the Millennium Ring from a merchant in Egypt (the Evil Spirit's previous host) with 666 ATK and 666 DEF points. The US version {{Bowdlerise}}d it to 1000/1000.[[note]]In the [[TabletopGame/YuGiOh real-life game]], the Attack and Defense stats for nearly all cards are some multiple of 50, before modifiers. It is probably no coincidence that the only exceptions to this rule were introduced in one duel before the rules for the RealLife version of the game came out.[[/note]]
* ''Franchise/{{Digimon}}''
** In the Eighth Child arc of ''Anime/DigimonAdventure'', a prophecy stated that the BigBad Vamdemon (Myotismon in the dub), [[NotQuiteDead who was thought to be killed moments ago]], will rise in [[{{Satan}} his true form]] at the hour of the Beast. And that evening, at 6:06 PM and 6 seconds, his insanely powerful OneWingedAngel form arises. Surprisingly, this plot point survived completely intact in the dub, and was even played up in the promotion for that part of the show.
** In the broader ''Digimon'' canon, the Seven Great Demon Lords possess a series of crests, the rings of which state of a "Level 666". No defined meaning is given to the statement, but given that no Digimon is classified by numerical power levels, odds are it's only there because for RuleOfSymbolism.
* There's an actual manga called ''Manga/SixSixSixSatan'', which is about humans, angels, and demons hunting for [[PlotCoupon magical artifacts]] and is [[RuleOfSymbolism loaded with Kaballahlistic imagery]]. For obvious reasons, it was released in America as ''O-Parts Hunter'', though is otherwise still the same.
* The title super-suit in ''Anime/{{Moldiver}}'' only worked for 11 minutes, 6 seconds at a time.
* Mr. Satan and Videl from ''Manga/DragonBall'' often had the number 666 plastered on their vehicles. Nothing evil about them (although the former is a bit of a prick) -- Toriyama was just throwing nods to the ThemeNaming.
* The ''Franchise/{{Gundam}}'' franchise has two HumongousMecha with 666 in their model numbers, the [=ZGMF-X666S=] Legend Gundam from ''Anime/MobileSuitGundamSEEDDestiny'' and the NZ-666 Kshatriya from ''Anime/MobileSuitGundamUnicorn''. With the Kshatriya it actually makes sense[[note]]It's a descendant of ''Anime/MobileSuitGundamZZ''[='s=] NZ-000 Queen Mansa and ''[[Anime/MobileSuitGundamCharsCounterattack Char's Counterattack]]''[='s=] NZ-333 Alpha Azieru[[/note]], but for Legend there's really no excuse other than [[WhatDoYouMeanItsNotSymbolic implying that the pilot is evil]]. Which is particularly odd since [[DesignatedVillain he clearly is not]]. [[spoiler:He is, however, [[CloningBlues a clone]] of the [[OmnicidalManiac very evil]] BigBad of ''Anime/MobileSuitGundamSEED''.]]
* In the manga version of ''[[VisualNovel/HigurashiWhenTheyCry Matsuribayashi-hen]]'' [[BreakTheCutie Mi]][[AGodAmI yo]] [[NietzscheWannabe Ta]][[DeadlyDoctor ka]][[AxeCrazy no]] says God keeps showing her the "one" face on the dice, but she'll force all the dice to be 6 on their faces. There are a number of dice on screen for the "one" dice, but only 3 for the "six" dice. Considering the speech given an issue or two before, this was likely intentional.
* In ''Manga/{{Berserk}}'', the Eclipse, which heralds the birth of a new member of the demonic Godhand, happens once every 216 years, or 6 x 6 x 6.
* In ''Manga/KatekyoHitmanReborn'', there are six powerful Mist-rings known as the Hell Rings. New Varia member [[DeadpanSnarker Fran]] owns the one with the number 666 on it.
* In the opening pages of the manga ''Manga/{{Biomega}}'', we see the protagonist driving along an abandoned bridge... going 666 km/h, of course.
* ''Manga/HighSchoolOfTheDead'' mentions the USA's National State of Emergency Tactical Regulation 666D.
* The ''Manga/LitchiHikariClub'''s ArtificialHuman Litchi runs on a series of commands issued by a clunky looking calculator. His activation code? "The Number of the Beast".
* In ''Manga/{{Yaiba}}'' the [[EvilWeapon Devil King Sword]] (Maoken in jap.) is kept in the room Six-Six-Six of Kaguya's moonbase. Probably it's called like that because of the sword inside it. It's also well guarded.
* In the infamous GainaxEnding of ''Anime/PantyAndStockingWithGarterbelt'', [[spoiler:Panty is sliced up into exactly 666 pieces by Stocking in her FaceHeelTurn.]]
* ''Anime/CTheMoneyAndSoulOfPossibility'' is full of 666 references, to emphasize the DealWithTheDevil theme.
* ''Manga/HayateTheCombatButler'' had a completely unintentional example: in the first popularity poll, Isumi got 666 votes. The chapter revealing this joked about how bizarre it was for her, of all people, to get that number.
* Around the beginning of the Fishman Island arc, ''Manga/OnePiece'' started a "Where are they now?" side story where chapter covers show what characters of varying importance are now doing after all the time that's passed. The chapters featuring characters from Impel Down, TheAlcatraz where each floor is its own special brand of Hell, take place during the 660s, and the final cover for this group is chapter 666.
* A cruise ship run by a MonsterOfTheWeek in ''Anime/SailorMoon'' has a maximum passenger capacity of 666.
* In ''LightNovel/ACertainMagicalIndex'', Creator/AleisterCrowley is eventually revealed to have used the CodeName [=Beast666=].
* With the premise of ''LightNovel/HighSchoolDXD'', this trope was inevitable. Called "Trihexa", it is considered to be the most powerful monster of the series that other mythologies, upon seeing it, claim that even they can't destroy it.
* ''Manga/BloodBlockadeBattlefront'' featured some genetically engineered monsters with a lifespan of 6 hours, 6 minutes, and 6 seconds.

[[folder:Card Games]]
* ''TabletopGame/MagicTheGathering''
** Perhaps fittingly, the card classified under Multiverse ID 666 [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=666 is a black spell that turns you into an undead planeswalker]].
** Innistrad, the block with a horror theme, [[http://www.wizards.com/magic/magazine/article.aspx?x=mtg/daily/arcana/666 was first announced on the 666th Magic Arcana]]. In addition, [[http://markrosewater.tumblr.com/post/21786917572/the-total-number-of-cards-in-the-current-block-is-666 the number of cards in the block also totaled 666]]
** The Mythic Rare [[http://www.examiner.com/article/ranking-the-titans-magic-the-gathering-s-2011-titan-cycle Titan]] cards are all 6/6 creatures with 6 converted mana cost.
** The VideoGames spin-off ''Duels of the Planeswalkers 2012'' states that Nicol Bolas, one of the evilest character in the verse, is 60 foot tall, 60 foot wide and weighs 60 tonnes. (He's a dragon by the way)
* In Poker, a three-of-a-kind made of sixes is colloquially known as "The Beast", though this invokes the erroneous "three sixes in a row" version.

[[folder:Comic Books]]
* Creator/MarvelComics' main universe is Earth-616. The term was created around the time of Alan Moore's run on ''ComicBook/CaptainBritain''. Moore's son-in-law said that Moore intentionally used a random number with no meaning (as a deliberate contrast to Franchise/TheDCU, where the main universe is Earth-1, with the idea being that Marvel's "main" Earth is just one random universe out of many, no more or less important than the rest), but artist Alan Davis said it was created by the previous writer David Thorpe, who intentionally used the Number of the Beast to indicate his feelings about superheroes.
** Marvel also has Earth-666, in which everybody is some sort of horror movie monster.
* ''Franchise/TheDCU''
** There is a demonic BigBad called Neron which, numerically, translates as 666.
** In the pre-''52'' DC multiverse, the Wildstorm 'verse had supervillains from an alternate dimension designated 666, where the bad guys won because the heroes never killed villains. They were shocked to meet the Authority, and dead shortly thereafter.
** Wildstorm also had a CrisisCrossover called "The Number Of The Beast", featuring a logo of three sixes arranged to have one-third turn symmetry.
** {{Green Lantern}}s were forbidden from going to the world Ryut, where all life was obliterated by a [[AIIsACrapshoot Manhunter]] atrocity in the distant past. When Abin Sur crash lands there, he uncovers the prophecy of the [[ZombieApocalypse Blackest Night]], and the [[EldritchAbomination Anti-Monitor]] is turned into the Black Power Battery there. Earth is sector 2814 -- anyone wanna guess what sector Ryut is?
* ''ComicBook/KingdomCome'' has an Anti-Hero whose name is 666. Not only that but he has a huge "6" tattoo on his face and two more 6s on his chest. Alex Ross used Brian Azzarello as the model.
* The address of the title character in ''ComicBook/JohnnyTheHomicidalManiac'' is 777. A man taking a survey points this out and jokingly asks if it's the number for Heaven. Johnny growls "Does this look like Heaven?" According to the comic, 777 is the "number of the moose".
* In ''Comicbook/{{Hellboy}}: Wake the Devil'', Karl Ruprect Kroenen plans to usher in the apocalypse with an army of 666 golems. When Herman von Klempt points out that this is far too few golems to conquer ''anything'', Kroenen replies [[WhatDoYouMeanItsNotSymbolic "The number is symbolic."]]
* The French graphic novel ''[[http://tinyurl.com/cgjthd 666]]''. It has a sequel, ''[[http://tinyurl.com/d3lssd 6666]]'' (which is the year the story is set in).
* ''Creator/WaltDisney's Comics and Stories'' issue #666 contains the first English printing of the story "Mickey's Inferno", an adaptation of ''[[Literature/TheDivineComedy Dante's Inferno]]''. This being Disney, they don't even mention the number when they talk about the story in the afterword.
* Issue number 666 of ''Franchise/{{Batman}}'' features a BadFuture where Batman's son Damien takes the cowl after the former's murder. Discount symbolism at its finest.
* In ''ComicBook/JudgeDredd'', iso-block 666 is used to contain the most dangerous criminals in Mega-City One.
* The ComicBook/XMen snuck some of their members into a hostile installation once by pretending they were unconscious, their bodies marked with numbered tags. Dr. Hank [=McCoy=] is known as the Beast; one guess what number he put on ''his'' tag.... And when one of the {{mooks}} commented on the number, Hank immediately jumped into action and knocked them out. That's right, one of the greatest geniuses in the Marvel Universe he based his infiltration strategy around a joke.
* In issue number 666 of ''Franchise/{{Superman}}'', Superman dreams about killing all his enemies and taking over Hell.
* In ''Flesh'': "Texas", [=McGurk=] brands Gorehead three times with a symbol that looks like the number 6. This is enough for Pastor Sunday to declare that Gorehead is in fact Satan.
* ''Comicbook/GhostRider'': the "Vicious Cycle" arc had Johnny Blaze accidentally bring Lucifer with him when pulling an EscapedFromHell stunt, at which point Lucy fragmented and possessed 666 recently-dead people.
* The first ''Franchise/SilentHill'' comic, ''Dying Inside'', mentioned and invoked this trope, when the main character declared a door code to be her own personal NumberOfTheBeast. She had issues.

[[folder:Comic Strips]]
* In ''ComicStrip/{{Nemi}}'', one of Nemi's friends tells her that if you remove all letters that are not Latin numerals in the inscription on the Pope's hat, they add up to 666, leading Nemi to ponder if the hat is there to hide the horns.
* ''ComicStrip/TheFarSide'' got in on it with Satan glowering at a confused painter, and "999" over the cave leading to Hell.
* ''ComicStrip/{{Foxtrot}}'' has a subtle example. While playing the game '[[VideoGame/DukeNukem Duke]] VideoGame/{{Quake}}[[VideoGame/DukeNukem m]]', Jason, having just finished level 5, cheerily explains "Only 661 levels to go!" You do the math.

[[folder:Fan Works]]
* ''Fanfic/MyImmortal'' is filled with this number, largely because the MarySue protagonist is supposed to be a satanist, and yet [[FridgeLogic Voldemort is referred to as Satan]].
* ''Plan 7 of 9 from Outer Space''. The heroes are looking at a floor plan in the SupervillainLair. Level 666 is just marked: Trust Me [[YouDoNOTWantToKnow You Don't Want To Know]].
* The SoBadItsGood [[Literature/HarryPotter Remus/Sirius]] {{lemon}} ''Passion Night'' has 666 words. Whether this is an amusing coincidence or evidence of it being a TrollFic is unknown.
* In the beginning of the 25th chapter of ''Fanfic/TheUltimateEvil'', [[spoiler:Valerie Payne is [[DemonicPossession possessed by Shendu]]]] in a Hongkongese hotel room that's numbered 666.
* A meta example in ''Fanfic/AdviceAndTrust''. [[{{WAFF}} Asuka's Birthday Party]] went up on page 666 of the Sufficient Velocity thread, simply for the sake of irony. The author even ''locked the thread'' to make sure that it went up on that page.

* In ''Film/{{Bedazzled 2000}}'', the protagonist can contact {{Satan}} with a pager, using the number...
* In ''Film/TheBurbs'', Ray and Art go over to the Klopecks house and knock on their door. The first knock changes the address number on the Klopecks' wall plaque from 669 to 666. The second knock knocks over the plaque, unleashing a horde of bees.
* The [[Film/ChildrenOfTheCorn666IsaacsReturn sixth]] ''Franchise/ChildrenOfTheCorn'' film shows that it means business by having 666 as its numbering instead of a roman number like the previous films.
* In ''Film/AClockworkOrange'' [[VillainProtagonist Alex]] is seen with two of his former friends, now police officers, whose uniform numbers are 665 and 667. Since Alex is between them, that makes him 666.
* The directors of ''Film/{{Devil}}'' were positively thrilled that their location, a real office building that hadn't opened yet, had the address number 333 (close enough).
* Hell in ''Film/TheDevilsCarnival'' has 666 rules. [[EarWorm All six-hunded sixty-six rules are policed, all six-hundred sixty-six rules you must heed.]] There are... consequences, otherwise.
* The Gregg Araki flick ''Film/TheDoomGeneration'' is filled with references to this number. Among other things, every purchase made by the main characters comes to a total of $6.66, and the female lead had an SAT score of 666 in high school. By the way, SAT scores end in 0.
* Played with in the 1999 film ''Film/EndOfDays''. Apparently, people who saw the number of the beast in their dreams/visions didn't realize it was shown upside down, so the number of the beast was 999 instead of 666. The Devil will then try to return on the last day of the year, for every year ending in 999 (999, 1999, 2999, etc). [[CriticalResearchFailure except they used Roman Numerals back then.]]
* In ''Film/EscapeFromLA'', the code that unleashes the worldwide {{EMP}} is 666.
* In ''Film/HalfBaked'', Tommy is scribbling over a calendar page of the big inmate who's been stalking him, at one point screaming "666, the mark of the beast!!!"
* In ''Film/HighlanderEndgame'' the Watchers reveal that BigBad Jacob Kell has decapitated a grand total of 661 immortals so far. Three guesses how many more people he'll have killed when it's all over.
* In ''Film/LittleNicky'', when the titular character gets hit head on by a garbage truck, [[RunningGag not the first time he was hit by a moving vehicle]], his two fanboys John and Pete get splattered with his blood, which forms a 666 pattern on Pete's shirt. It stays there for the rest of the film.
* In ''Film/TheNinthGate'', guess what the keypad code to Satanic book collector Boris Balkan's private elevator is?
* The origin of the "modern" use of the Number of the Beast is probably ''Film/TheOmen1976''. They even released a [[Film/TheOmen2006 remake of the film]] [[MeaningfulReleaseDate on June 6, 2006]] nationwide. The original came out in the UK on June 6, '76... close enough.
* In the beginning of ''Film/ThePhantomOfTheOpera2004'' the chandelier that the Phantom [[spoiler: had dropped thus starting the fire that destroyed the theater]] is sold on an auction under listing number 666.
* Officer Vickers from ''Film/PsychoCop'' has the number 666 tattooed on the back of his hand. [[Film/PsychoCopReturns In the sequel]], it is his badge number.
* The code for the suitcase in ''Film/PulpFiction'' is 666.
* In ''Film/ReignOfFire'', a ruined sign on a road states that London is 66 miles away. Aside from other things scribbled onto the sign, a large 6 is scratched in above the 66.
* Used in ''Route 666'', which involves an abandoned stretch of highway nicknamed such after the mysterious death of a prison chain gang.
** There was a real Route 666, which was a turnpike of Route 66. It's Route 491 now.
* The serial killer from ''Seed'' was captured after killing this many people.
* This is used as an address in ''Film/SilentNightDeadlyNightPart2'' and ''Film/{{Inside}}''.
* ''Franchise/StarWars'': "Order 66" in ''Film/RevengeOfTheSith'', which might double as a reference to [=WW2=] Executive Order 9066, which interned Japanese civilians.
* ''Film/StayTuned'' loves this trope; after all, it's about a satellite TV network run by {{Satan}} himself. Said network has 666 channels and airs stuff like ''[[Series/BeverlyHills90210 Beverly Hills 90666]]''.
* ''Film/TheDarkSideOfTheMoon'': 665 ships are said to have been lost in TheBermudaTriangle. Guess [[{{Satan}} who's responsible]] for these disappearances?

* Used in the Creator/RobertAHeinlein novel ''Literature/TheNumberOfTheBeast''. One of the protagonists builds a device that makes it possible to move arbitrarily through a six-dimensional space-time to [[AnotherDimension multiple universes]]; the number of possible destination universes is (6^6)^6 (10,314,424,798,490,535,546,171,949,056), which when written sloppily one of the characters mistakes for the traditional 666. This prompts a discussion over whether biblical prophecy actually refers to the 6-dimensional space-time geometry and the bad guys they've already encountered. (The conclusion is that there are enough similarities to at least be cautious about it.)

** The address of Famine's club is 666, which he has advertised in a giant neon sign on the side of the building.
--->It was just a number, of course. If you kept counting, you'd reach it eventually. But still, you had to smile.
* Literature/{{Discworld}}: In ''Discworld/ReaperMan'', 668 [[Franchise/ANightmareOnElmStreet Elm Street]], Ankh-Morpork, is the address where the all-undead Fresh Start Club holds its meetings.
* In ''Literature/WarAndPeace'', Pierre Bezukhov calculates the Hebrew number equivalent of Napoleon's full title (''L'Empereur Napoléon'') to be 666, shoehorns his own name to yield the same number (''L'Russe Besuhof''), and thinks that he's destined to kill Napoleon or at least for something great. In reality, the scheme he used yields 661 for Napoleon, not 666, rendering all his actions based on this observation bunk.
* In Book the Sixth of Lemony Snicket's ''Literature/ASeriesOfUnfortunateEvents'', ''The Ersatz Elevator'', the address of the Baudelaires' new home is 667 Dark Avenue. In addition, it has sixty-six floors.

* Creator/JohnHodgman's ''Literature/TheAreasOfMyExpertise'' includes a list of (North American) phone numbers beginning with the prefix "666" including "a bunch of Satanists who got lucky" and "the author's home phone number".
* ''Literature/NightmareAcademy'', by Creator/FrankPeretti has a rather contrived situation near the end of the book in which a row of buildings is being demolished and one of the characters needs to stop it by putting in a code that corresponds to... some technical detail. Anyway, it ends up being 666 (or 666.0 if you want to be picky, and the computer did). Lampshaded by the kid stopping it when he figures it out.
-->"Twelve times 55.5 is... Really?"
* In Creator/RobertRankin's ''Apocalypso'', every dimension is assigned a Greek letter and a number. Hell is Omega 666.
* Conservative shock commentator Ann Coulter released a book called ''Godless'' on 6/6/06. She said it wasn't coincidence.
* Surprisingly averted in the ''Literature/LeftBehind'' series. Nicolae Carpathia is the aforementioned Beast himself, but the obligatory references to 666 are all [[FridgeBrilliance subtle]]: a fixation with the number 216, an assistant named [[MeaningfulName Viv Ivins]], and the numerology of his full name. Nobody brings any of this up directly; they have other, less coincidental, ways of knowing he's the Antichrist.
** Likewise, when the MarkOfTheBeast finally shows up in the series, the coding for the marks are all the results of equations where different operations are plugged, between the sixes, such as 30 (6 x 6 - 6), 18 (6 + 6 + 6), 42 (6 x 6 + 6), etc.
* In Regina Doman's [[FairytaleNovels ''The Shadow of the Bear'']], the villain uses "666" as the keypad code for his apartment.
* In ''Literature/DeathByGaslight'' by Creator/MichaelKurland, the members of the Hellfire Club carry tokens that read DCLXVI. Professor Moriarty helpfully reads from Revelation 13.
* Used in The Lord of Opium, where it's mentioned that [[SlaveMooks eejits]] are marked with 666 after their brainwashing operation.
* in ''Literature/TheLaundryFiles'' the 666th RAF Strategic Bomber Squadron "The White Elephants" is a secret unit flying militarized Concordes equipped with nukes, designed to hit a certain site in Russia where the boundaries between dimensions are especially thin and something with too many angles and tentacles might manifest.


[[folder:Live Action TV]]
* ''Series/DoctorWho'':
** The atmosphere readings of "The Impossible Planet"/"The Satan Pit" are 66.6, the gravitational field is "6^6 every 6 seconds", and the name of the base, "[=SB6=]" is seen gradually melting into "666". The two-part episode was even aired over the week of 6th June 2006, or 6/6/06. Also, the Ood go to work to the sound of Ravel's Bolero, which Torvill And Dean famously skated to in the 1984 Winter Olympics -- and received perfect 6s for artistic impression.
** As an extra metatextual touch, the official web site's Fear Forecasters gave "The Impossible Planet" a Fear Factor score of 3/6/6/6 -- on a scale that usually only goes up to 5. ("The Satan Pit" got straight 5s.)
** The coordinates for The Void -- the Whoniverse equivalent to Hell -- are all sixes, as seen in "Doomsday".
** Also invoked in "Midnight": When Mrs Silvestri starts repeating what everybody says, the teenage Jethro says "six six six" to get her to repeat it.
** In "Mummy on the Orient Express", the Foretold kills its targets in ''66'' seconds, and each time a stopwatch appears on screen to count down the seconds remaining. Guess how many times the watch appears? ‘‘Six''.
** The [[ArcWords prevalence of 666]] in the Doctor Who universe has led observant fans to come up with [[{{WMG}} theories]] to explain it.
* In the ''Series/TheTwilightZone1985'' episode "Dealer's Choice", a group of gamblers find themselves playing poker against the Devil. Every hand the Devil receives includes three sixes. When one of the players ends up playing for his soul, he attempts to use this to his advantage by invoking dealer's choice and choosing Low Ball as the game.
* ''Series/{{Reaper}}'':
** Sam's house number is 667. In one episode, he hits the snooze button on his alarm clock and the numbers turn red and read "6:66".
** Played for pun later: The demon rebellion needs the Number of the Beast to summon the Devil...his cell phone number, specifically.
* One episode of ''Series/TheXFiles'' ("Orison") had Scully's alarm clock read 666 twice, warning her about the evil man after her. It proved to be surprisingly effective as a piece of mis-en-scene.
* An episode of ''Series/FridayThe13thTheSeries'' did a more "realistic" twist on this by having some bad stuff happen at exactly 3:33 AM.
** Possibly a reference to Jesus's Crucifixion, which had Him die at 3:30 PM.
* An episode of ''Series/{{QI}}'' had Stephen Fry asking the teams what the number of the beast was (Johnny Vaughan fell for the 666 trap). After Fry had revealed that 616 was the actual number, one of the panel concluded that 666 must be his fax number!
* In the ''Series/QuantumLeap'' episode "The Boogieman", Sam and Al visit a home with the house number 966. As Al crosses the threshhold, the top 6 becomes loose and spins around to reveal a 666 [[spoiler:because Al has been supplanted by the devil, who has hijacked this leap.]] Luckily, [[spoiler:it was AllJustADream!]]
* ''Series/StargateSG1'' visits a planet whose designation is [=P3X-666=] in the two-part episode "Heroes". [[spoiler:Dr. Frasier dies there.]]
* In ''Series/PointPleasant'' the mark on the protagonist's eye is a series of three six-figures, overlapped and rotated in a particular pattern. It's probably a ShoutOut to the 666 mark on Damien's head in ''Film/TheOmen'', which is three sixes with their tails in the center. The mark of ''Point Pleasant'''s heroine is a circle with three tails curving outward.
* ''Series/{{Supernatural}}'': There was a rather reviled Season 1 episode called "Route 666", and then there were the 66 out of 600 possible seals that needed to be opened in order to set Lucifer free from his prison. When Dean wakes up in a post-Apocalypse BadFuture where Lucifer is winning, there's a movie theatre with NOW SHOWING: ROUTE 666. When Crowley (the King of Hell) rings up our heroes in "Clip Show", the number displayed is 666.
* ''Series/TheMightyBoosh'' episode ''Nanageddon'' features a demon going on a rampage at a bingo night. As she reveals herself, the bingo caller announces the number: ''"All the sixes - 666."''
* An episode of ''Series/{{Frasier}}'' showed Frasier's old agent Bebe staying in a hotel room numbered 666.
* The third episode of ''Series/{{Crusade}}'' has a religious fanatic setting a time bomb at 666 seconds. Rather unlikely for a "God-fearing" nut to use the Number of the Beast.
* ''Series/TheGlassHouse'' reported the discovery that 616 might actually be the number of the beast, and noted that, by international dialling, Canberra's former area code was + 61-6.
* One of the threats of the week for the ''Series/BigWolfOnCampus'' team was a wrestler who would cause ''the apocalypse'' once he got to 666 victories.
* One episode of ''Series/CriminalMinds'' had a Satanist whose name was '''F'''loyd '''F'''eylin '''F'''errell. F is the sixth letter of the alphabet.
* An episode of ''Series/That70sShow'' had Laurie, Eric, Hyde and Kitty playing cards with their youth minister. Laurie ends up having three 6 cards (and this is after she tried to come on to him). The minister promptly gets up and leaves.
* The titular town of ''Series/EerieIndiana'' is listed as having a population of 16,661
* ''Series/SixHundredSixtySixParkAvenue'' where if you want to live at 999 Park Avenue, you have to sell your soul to the Devil.

* "Number Of The Beast" by Music/IronMaiden, which even begins with the above quote from Revelations. The songwriter, LeadBassist Steve Harris, [[http://images.rapgenius.com/e34754151fd45601bfc959ed72d18d3f.333x500x1.jpg has also worn a]] FunTShirt reading "666 The Number of the Beast, 664 The Bloke Next Door".
* Music.{{Slayer}} planned to release an album on 6.6.06, but due to problems they could only release a single. The album? ''Christ Illusion''. By amusing coincidence, 6.6.06 was also bassist/lead singer Tom Araya's 45th birthday.
** This was successfully done however by AFI who released their album "Decemberunderground" on 6.6.06
** Ditto for Music/{{Lordi}}, who released their Series/EurovisionSongContest winner ''Hard Rock Hallelujah'' as a single in the UK on 6.6.06.
** Music/{{Metallica}} played a concert in Berlin on 6/6/06.
* "666" in metal in general is very common due to its satanic connotations. Bands that have made songs with the number include Music/{{Helloween}}, Anvil and Burn to Black as well as many others.
** Danzig's album ''6:66 Satan's Child''.
* The death rap group Three 6 Mafia (aka Triple Six Mafia), once notorious for their Satanic lyrics and references to the occult. However the group has since stated that the name is just a reference the fact that their group started out with three members and ended up with six. That, and the fact that back when they were just starting out, they needed to put out something that would [[NoSuchThingAsBadPublicity draw attention to themselves]].
* ''666'', a ConceptAlbum thematically centered on [[TheBible the book of Revelation]], was the only NewSoundAlbum Aphrodite's Child ever released (in the two years between the completion of the album and its release, the band broke up).
* Alluded to by the Christian Post-hardcore band Underoath's DVD which has "777" in its title due to their religious beliefs.
** Electronica group System 7 also has two different albums both titled ''777''. (The first of these is titled ''System 7'' [[MarketBasedTitle except for]] in the United States, because of [[UsefulNotes/MacOS Apple's System 7 operating system]].)
* Parodied (somewhat) in the song "665: The Great Bean" by [[http://www.theenid.com The Enid]].
* Parodied by Green Jelly with their 1994 album ''333''.
* Blackened Thrash band Destroyer 666. They take it to extremes, portraying themselves as Australian anti-Christs.
* Music/{{Soundgarden}}'s songs "665" and "667", which are parodies of other metal bands' Satanic imagery.
* Heavy metal band Music/{{Loudness}} has an instrumental titled "222" and (more recently) a song titled "#666".
* The German trance band 666.
* The song "Six Sixty-Six" by Christian-folk singer Larry Norman, covered by his fan Frank Black, is a straightforward retelling of the prophecies about the Antichrist in Bible fanon.
* Murdoc Niccals, the fictional bass player of Music/{{Gorillaz}}, was born on June 6, 1966 (6/6/66) and is a Satanist.
** He also refers to [[PunnyName "Number of the Beats"]] as a band name they had been considering.
* Music/SteveVai was born on June 6, 1960 (6/6/60) and has skills that could very well be described as not of this world.
* Music/{{Slipknot}}'s song "The Heretic Anthem" featured the chorus: "If you're 5-5-5 then I'm 6-6-6", though the lyrics feature no real Satanic overtones and the use of the number was really just for shock value.
** Since 555 is commonly used as the exchange for phone numbers in movies and television, the line could be interpreted to mean that if you're trying to fit in and be acceptable, he's trying to be edgy and unacceptable.
* ChristianRock group [=DeGarmo=] and Key's 1984 album "Communication" included a song ttled Six, Six, Six. It gained attention [[http://www.youtube.com/ix wach?v=Z7Cdxl4INfw as one of the first CCM music videos]] to appear on Creator/{{MTV}}. It also became infamous for MTV ordering an edit removing a scene where a man kicks a burning trash can down, [[http://www.youtube.com/watch?v=vUVj47rpuoo briefly setting the man representing the Antichrist on fire]].
* "666 - The Enemy Within" by Music/HammerFall.
* Music/ThePixies reference this in "Monkey Gone To Heaven" from ''Music/{{Doolittle}}'', with the lines "man is five", "the devil is six", and "god is seven."
* "Disconnected 666", a spooky audio collage by Cop Shoot Cop, has an excerpt from a prerecorded disconnection notice repeating the number 666 over a backdrop of busy signals.
* Mentioned in The Wicked End by Music/AvengedSevenfold.
* "Your Sweet Six Six Six by Finnish love metal band HIM.
* The album cover for Music/BlackSabbath's ''Sabbath Bloody Sabbath'' sports a demon with 666 engraved on its body.
** In a weird coincidence, the studio version of Sabbath's self titled song has a running time of 6:16.
* The LP cover of Music/DeepPurple's ''The Book Of Taliesyn'' lists the running time of "Exposition/We Can Work It Out" as 6:66.
* Music/PatoFu has a song called "Capetão 66.6 FM" ("Capetão" being Portuguese for "Big Devil").
* Music/TheDingees' album ''Rebel Soul Sound System'' has a fake (and unreadable) bar code with the UPC "06660 06660".
* The first disc of DoomMetal band Reverend Bizarre's final album, ''So Long Suckers'', is sixty-six minutes and six seconds long. According to WordOfGod, this is not coincidence.
* Music/{{Genesis}}' song "[[Music/SuppersReady Supper's Ready]]" has the line "Six six six is no longer alone". Since the segment it's from is a musical adaptation of Revelation, this probably isn't terribly surprising.
* Proto-heavy metal band Atomic Rooster were ''seriously'' into magick and gematria. Their best-known track ''Devil's Answer'' carries a coded suggestion that 666 is not the number to look out for. Apparently ''357'' is the badass number. Aleister Crowley and others also thought so.
* Music/JohnZorn signed and numbered 666 copies of the album "The Satyr's Play/Cerberus" (2011) and produced 66 copies of a limited edition book version which were individualised and hand bound in black goat skin.
* The late Harlem rapper Big L mentions in the song "Devil's Son" that these numbers are on his scalp if one looks closely.
* For the 666th episode of his long -running radio show A State of Trance, Music/ArminVanBuuren dedicated the episode to the [[DarkerAndEdgier darker and eviler]] side of {{trance}} music (primarily psychedelic and tech trance).
* In an unusual example for a religious group, the ChristianRock band Music/{{Red}} released their debut album, ''End of Silence'', on 6/6/06.

[[folder: Mythology & Religion]]
* The TropeNamer comes from the Literature/BookOfRevelation 13:18 from Literature/TheBible (KJV): "Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and [[LampshadeHanging his number is six hundred threescore and six."]]
* Another example from the Bible occurs in [[Literature/BooksOfKings 1 Kings 10:14]] (KJV): "Now the weight of gold that came to Solomon in one year was six hundred threescore and six talents of gold.", mnaking this OlderThanDirt.

[[folder:Pro Wrestling]]
* There's a small and odd federation in Japan called 666. One notable character is President Ramu, a demonically-possessed wrestler with super strength for her size. Which is good, given that she'd fit under CuteBruiser. Note she is NOT the least likely champion they've ever had....
* Back in Wrestling/{{WCW}} as the original [[Wrestling/NewWorldOrder nWo]] [[PowerTrio Wolfpac]], [[Wrestling/TheKliq Kliq]] members Wrestling/KevinNash, Wrestling/ScottHall, and Wrestling/SeanWaltman sometimes all wore shirts with number-6 pool balls on them at once. [[GettingCrapPastTheRadar Though they had the excuse that Waltman was called Syxx at the time and for more than just that reason at that…]]

[[folder:Tabletop Games]]
* Ed Greenwood sometimes used the number 666 (or variations thereof) when creating Forgotten Realms spells for the 1st and 2nd editions of ''Advanced TabletopGame/DungeonsAndDragons''.
* Speaking of ''Dungeons & Dragons'', according to most editions' Dungeon Master's Guide, one of the planes, the Abyss, has supposedly infinite layers, but "conventional wisdom" says the bottom layer is the 666th.
** The demon goddess Lolth has her home on the 66th layer.
* The secret Grey Knights chapter of [[SuperSoldier Space Marines]] in ''TabletopGame/{{Warhammer 40000}}'' is Chapter 666. They are an all-psyker, elite-among-elites group serving under the aegis of the Inquisition's Ordo Malleus and dedicated to combating Daemonic threats.
** Also before they join they have to go through the 666 Rites Of The Emperor, which can be described as 666 {{Mind Rape}}s.
** [[ArsonMurderAndJaywalking And their favorite]] SoundOff, the Canticle of Absolution, is [[NumerologicalMotif sixhundredsixtysix words long]]
** It's implied somewhere that they chose this number [[GenreSavvy specifically because of the bad connotations]]; the Grey Knights are such an elite force that they can handle whatever it means for them.
* Also in ''TabletopGame/{{Warhammer 40000}}'', Zarakynel, the Keeper of Secrets model produced by Forge World, costs exactly 666 points to field. (This is because Slaaneesh's magic number is 6. Ann'grath (Khorne) has a points costs of 888, similarly.) Interestingly, Slaanesh is the only Chaos God in the backstory who does not exist before far into the future.
** As explained in the Daemon codex, due to way time flows in the Warp (that is, very erratically) despite being created about 30 000 years in the future, Slaanesh has in a way always existed, and never existed. [[MindScrew Warp is confusing like that.]]
* In Sanguine Productions' ''TabletopGame/{{Ironclaw}}'', the use of Black Magic can have dangerous side effects. Namely, when three sixes appear in any dice roll involving it. This includes skill rolls, resistance rolls, and difficulty rolls. Just to maximize this effect, the Difficulty Dice for Black Magic are, uncharacteristically, almost all d6s.
* ''TabletopGame/InNomine'' is an RPG system where players take sides in a demon vs. angel battle between hell and heaven. The game system uses d666 (3 six-siders for all rolls). Bad things happen to angelic characters whose players roll all 6's, conversely good things happen if you roll all 1's (the Trinity). This is reversed for demonic characters.
* In ''TabletopGame/{{Rolemaster}}'', a roll of 66 indicates a very unexpected result.
* ''TabletopGame/HunterTheVigil'' features the Lucifuge, a secret order made up of people who have inherited the powers of Hell from demonic parents. The head of the organization (also known as the Lucifuge) has spent centuries keeping track of them, and knows exactly how many are on Earth at any one time. Take a guess.

* The catalog number for the auctioning of the infamous chandelier in ''Theatre/ThePhantomOfTheOpera'' is 666.

[[folder:Video Games]]
* Beelzebub from ''VideoGame/RagnarokOnline'' has a starting HP of 6,666,666 HP. And he looks like a Steel Chon Chon. Changing to his true form gives him more HP.
* ''Franchise/ShinMegamiTensei'':
** Beelzebub (human form) in ''VideoGame/ShinMegamiTenseiIIINocturne'' has 666 HP.
** Evil Land gives 666 damage to demi-humans at LV 6.
** Satan's design has '''6''' arms, '''6''' wings, and '''6''' breasts.
** In a display of grand irony, one of the DLC bosses in ''VideoGame/ShinMegamiTenseiIV'' is [[spoiler:ArchangelMichael]], who, despite who he obviously works for, has an attack that inflicts a fixed 666 HP of damage.
* ''VideoGames/TeamFortress2'' has the Ghost Town Halloween Event, which is an extremely challenging version of [[ManVersusMachine Mann Vs Machine]], reskined as zombies.
-->''"[[LampshadeHanging How many zombies? How does 666 sound, fear friends? Because it sounds like a candy-ass pile of crap to us! 666 is where we STARTED. But where we ended was MORE THAN EIGHT HUNDRED! That said, we're still calling it "Wave 666", because we asked Glenn Danzig and he said that sounded way more badass than "Wave More Than Eight Hundred".]]"''
-->-- '''[[http://www.teamfortress.com/blizzbobarrabas/ Promotional description for Wave 666]]'''
** The amount of enemies is actually 911 robots and 9 tanks, and additional Spies and Snipers which continuously spawn for as long as you play.
* ''Franchise/{{Castlevania}}'':
** In ''VideoGame/CastlevaniaSymphonyOfTheNight'', Death is level 66, the vampire Olrox and the Succubus have 666 HP, and the Malachi (which was ''supposed'' to be called {{Cthulhu|Mythos}}) and the Fire Demon gives 666 experience points.
** In {{Metroidvania}} games, Dracula typically has 6666 HP. ''VideoGame/CastlevaniaOrderOfEcclesia'' averts this trope by giving him 9999 HP instead. Then again, '9' is just '6' upside-down.
** The three Dominus glyphs in ''VideoGame/CastlevaniaOrderOfEcclesia'' CastFromHitPoints: Dominus Anger and Dominus Hatred consume 1/6 of Shanoa's HP with each attack, while Dominus Anger raises all of Shanoa's stats by 66 at the cost of 66 HP per second.
* ''VideoGame/ChronoTrigger''
** Magus, the leader of the Fiends, has 6666 HitPoints and 666 Magic Points as a boss.
** Bashers and Lashers, two minor enemies in the Ocean Palace, have 666 HitPoints.
* One of the Chemist's mixes in ''VideoGame/FinalFantasyV'' is a "Dark Potion" which deals 666 damage.
* ''VideoGame/SecretOfMana'' has the [[TheDragon Dark Lich]], who has 6,666 HP.
* In ''VideoGame/SagaFrontier'', the Pain Doubler spell under Zamza's Evil Magic library deals 666 damage... which sucks quite a bit since the average damage in the game is four digits. Of course, when used on the player, it can be a death sentence, since max HP tops out at 999.
* In ''VideoGame/{{Pikmin}} 2'', there's a [[DefangedHorrors creepy doll's head]] that's worth 670 pokos; in the Japanese game, it's worth 666.
* ''VisualNovel/{{Tsukihime}}'' features a villain called Nrvnqsr Chaos who controls 666 animal familiars. And Nrvnqsr (pronounced 'Nero') is numerically equal to 666.
* In the old ''VideoGame/UltimaII'' computer game, the Earth was located at coordinates (6,6,6) in the solar system.
* ''VideoGame/SNKVsCapcomSVCChaos'' has an overall cast of 33 characters, with 663 pre-battle dialogues for each of them... okay, not '''each''', because Athena and Red Arremer have no dialogues between each other or their clones whatsoever. If they would be, though, it would result in a straight 666. [[CrapsackWorld May be excuseable.]] [[MoneyDearBoy Or maybe not.]]
* Instead of ''VideoGame/{{Doom}}'' "version 1.6", the producers went with "version 1.666".
** In the ''Ultimate Doom'', [=E1M1=] has 666 sidedefs.
** Doom also uses UDP port 666.
** Sector tags 666 and 667 are used for actions that require certain monsters to be killed. (instead of crossing a specific linedef)
** In ''VideoGame/Doom3'', there are lockers scattered around that contains items. One of them, however, contains an Imp. The locker's number goes without saying.
** During the E3 presentation of the ''VideoGame/Doom2016'' game, Bethesda's representative [[https://www.youtube.com/watch?v=QiinO9JPUGw&t=34s joked]] that they internally refer to the [=IdTech=] 6 engine the game runs under as [=IdTech=] 666.
*** In a super-obscure EasterEgg, viewing the music from the Cyberdemon BossBattle through a spectrogram reveals a repeating pattern of [=666s=] and pentagrams.
* In ''VideoGame/DevilMayCry4'', Dante gets a weapon called Pandora, which is a demonic briefcase [[SwissArmyWeapon that can transform into 666 evil forms]], which all seem to be big guns (along with its original purpose of containing all the world's evil and still holding onto hope, as its debut cutscene seems to imply).
* ''VideoGame/MaxPayne'' had a level where the access code for a different part of a lab was 665, which Max sarcastically comments as the "neighbor of the beast". In the sequel, the code to access the suites in Max's apartment is 667, and the "neighbor of the beast" line is echoed.
** Both mentions are based on a recurring joke in the developers' native country of Finland. Of course, with street numbers the neighbor would be 668, but apartments need not be numbered the same way.
* ''VideoGame/KingdomOfLoathing'' spoofs this with the 668 scroll, allowing you to summon the ''neighbor'' of the beast.
* In ''VideoGame/{{killer7}}'', Emir Parkreiner's locker is #666. Looking in locker #616 leads the player to Mask's final mask.
* In ''VideoGame/{{Bayonetta}}'', there's Route 666, a dangerous place where the heroine can be flattened by oncoming traffic (suffering a OneHitKill) if she's unlucky enough to end up on the wrong side while fighting enemies.
* The original ''VideoGame/{{Quake}}'' features a power-up called the [[InvincibilityPowerUp Pentagram of Protection]], which puts a red 666 on your armor counter, although that's just for symbolic and aesthetic purposes -- your health will not go down while this power-up is active, and anything that tries to spawn at your position will be reverse telefragged. Note that your armor will still take damage if you have any on.
* The demon morph SuperMode from ''VideoGame/{{Painkiller}}'' is activated by Daniel's absorption of 66 souls. At least, without a powerup that reduces the number to 50.
** The 666 Ammo card, obviously. However, the number on the card is written in Roman numerals (DCLXVI), which shows that the devs knew the ''value'' is important, not three sixes.
* ''VideoGame/Disgaea3AbsenceOfJustice''
** Mao calculates that it will take exactly 666 Nether hours (after Mao hijacks his "Hero" title) until HeroicWannabe Almaz becomes a full-fledged demon.
** And Maritsu Evil Academy has 666 bathrooms.
* In ''[[VideoGame/KingdomHeartsChainOfMemories Kingdom Hearts]] [[VideoGameRemake Re:]][[VideoGame/KingdomHeartsChainOfMemories Chain of Memories]]'', Marluxia's final form has a sleight that is activated by using three 6 cards, which forces Sora to break all of the cards within six seconds or face [[OneHitKill instant death]].
* 666 is the phone number for Hell in ''Franchise/SamAndMax'''s second SeasonFinale.
* The "All the 6s" level from ''VideoGame/{{Lemmings}}''. It's not even close to being a [[ScrappyLevel level from hell]], though -- actually more of a BreatherLevel.
** Several ports of the game replace "All the 6s" with a completely new level -- whether because of the NumberOfTheBeast reference or just because it's the ultimate BreatherLevel is difficult to say.
* ''VideoGame/AceCombat'':
** Galm Team from ''[[VideoGame/AceCombatZeroTheBelkanWar The Belkan War]]'' is the Ustio 6th Air Division, 66th Squadron. By the way, "Galm" is a mistranslation of "Garmr", a hellish wolf in Myth/NorseMythology that kills Tyr during the Ragnarök. And the Galm 1's call sign is "[[LouisCypher Cipher]]", in case you still didn't catch any symbolism.
** The final mission of ''[[VideoGame/AceCombat04ShatteredSkies Shattered Skies]]'', appropriately a ScrappyLevel with tunnel-flying, has Mobius One start at 6666 feet.
* The title antagonist of the first ''VideoGame/{{Diablo}}'' has 1,666 HP.
* Rubedo from ''VideoGame/{{Xenosaga}}'' is URTV #666.
* In ''VideoGame/WorldOfWarcraft'', [[ThatOneBoss Hogger]] has 666 health.
** There is a statue of a serpent in Zangarmarsh with 666 in its scales. However, it was far more common during The Burning Crusade and Wrath of the Lich King expansions than it is now. In fact, there was a warlock spell that did 666 base damage, but that has since been changed. There were also icons for warlock and demon spells with stylized 666's in them, these have all been removed.
* ''VideoGame/BlazBlue'' has Ragna, Nu-13 and Hazama give the line "Restriction 666 released" when activating their [[ArtifactOfDoom Azure Grimoires.]]
* In the [[{{Woolseyism}} English version]] of ''VisualNovel/{{Snatcher}}'', the date of "[[AfterTheEnd the Catastrophe]]" was moved from June 6th, 1991 (6/6/1991) to June 6th, 1996 (6/6/1996).
* ''VideoGame/EternalDarkness'' places great significance on 3:33 times on both digital and analog clocks.
* In ''VideoGame/FinalFantasyXIII'', the Tonberry staggers at 666%.
* In ''VideoGame/FiveNightsAtFreddys'', Foxy's height is 4.666 feet.
* In ''[[VideoGame/DigimonWorlddawnDusk Digimon World Dawn]]'' and ''Dusk'', the Digivolution requirements for [[spoiler:[=VenomMyotismon=]]] are level 66 with 6666 Beast experience (the game puts it, BST 6666). This is also a shout out to the anime.
** Slightly more subtle, in ''VideoGame/DigimonWorldDS'' a requirement for the character is 99990 EXP, which, if viewed upside-down, reads 06666.
* In ''VideoGame/LuminousArc3'', the first stage of the final boss will have 666 HP. [[spoiler:However, the final boss is an [[GodIsEvil evil god....]]]]
* In ''VideoGame/EndlessOcean: Blue World'', of all places, the PandorasBox salvage item with net the player 9,666 pelagos (the in-game currency). Notably, the only treasure to not have a multiple of ten (or a multiple of ten minus one) for its price.
* ''VideoGame/AsheronsCall'' featured an event boss, Bael'zharon, who when inspected, was level 666. There is also the White Rabbit, who has 666 in every stat (and [[GameBreaker instant-kills you]] when you inspect it.)
* TheVeryDefinitelyFinalDungeon in ''VideoGame/{{Purple}}'' has a prominent 666 on its entrance [[DieChairDie which you can freely break]]. The game in general uses {{Satan}} motif shamelessly.
* Several inferno units in ''VideoGame/HeroesOfMightAndMagic V'' utilize this: Nightmares and Hell Stallions have 66 HP, Pit lords and Pit spawns cost 1666 gold, Devils, Arch Devils and Arch Demons all have a maximal damage of 66, and cost 2666 gold (devils) or 3666 gold (the other two). Additionally, Devils have 166 HP (and Arch Devils have 199, turn that upside down).
* In chapter 5 of ''VideoGame/AliceMadnessReturns'', a wall in the Dolltown Cellar[[note]]in the room with the glass floor with hazards underneath[[/note]] has 666 affixed to it.
* In ''VideoGame/SpacePiratesAndZombies'', the ship known as the Brute (one of the strongest ships available from the Bounty Hunter faction) has 666 base health.
* In ''[[VideoGame/SeventhDragon 7th Dragon]]'' the total number of Dragons that live at the start of the game add up to 666.
* In ''VideoGame/SonicTheHedgehog2006'' we have the BigBad [[OurDemonsAreDifferent Solaris]], a sun god whose initial form upon being fused together features '''six''' stones on his back, '''six''' wings, and '''six''' horn pieces on his head. Note that this is a character whose raw power and cunning mind were separated into [[AlmightyIdiot a beast and]] a false prophet [[LouisCypher named after the Muslim devil and a pun on Mephistopheles respectively]].
* In ''Videogame/BioShockInfinite'', one of the upgrades for the [[PlayingWithFire Devil's Kiss]] Vigor costs six-hundred-and-sixty-six dollars.
* ''VideoGame/CookieClicker'':
** The Portal upgrade is a thinly-veiled reference to opening a {{Hellgate}}, and originally costs 1,666,666 cookies to purchase. It produces 6,666 cookies originally, and its upgrades cost 16,666,660, 166,666,600, and 1,666,666,000
** When you reach the end-stages of the [[spoiler:grandmapocalypse]], you can eventually form a covenant with the [[TheOldGods Elder Gods]], at a price of 6,666,666,666,666 cookies.
* In ''VideoGame/VagrantStory'', the FinalBoss's OneWingedAngel form has 666 HP and 666 MP.
* The [[FinalBoss final Impact boss]] in ''VideoGame/GoemonsGreatAdventure'', Devil Death God, has 6,666 HP.
* In the ''VideoGame/SaintsRow'' series, Stilwater's "The Krunch" and Steelport's "The Blood" are both hard rock and metal radio stations that broadcast at 106.66 FM. [[note]]In the first game, it was just 106.6, but close enough.[[/note]]
* Averted in the ''Franchise/{{Pokemon}}'' series. Pokémon #666, Vivillon, is a cute butterfly.
** It ''does'' kind of look like the famous ''Dictionnaire Infernal'' illustration of the insect demon Beelzebub if you squint a bit, though.
* In ''VideoGame/LollipopChainsaw'', Killabilly is said to be 666 years old.
* In ''Videogame/TheLogomancer'', [[BossBattle Nikolai's Regret]] has 6666 [[HitPoints willpower points]].
* One of the dozens of planets in ''VideoGame/{{Meteos}}'' is the PlanetHeck Jeljel which can be unlocked as playable by launching 666 Fire, Soil and Zoo meteos and 3 Dark meteos.
* Getting a [[{{Combos}} combo]] of 6 hits in ''VideoGame/{{Skullgirls}}'' is "Naughty", 66 is "Devilish", 616 is "Infernal", and 666 is "Diabolical".
* ''VideoGame/{{Touhou}}'' pokes fun at it a few times. In ''Imperishable Night's'' Extra Stage, the requirement for obtaining the last Extend you can gain from point items is 666 point items, the next being an impossible 9999 requirement. More fittingly, [[http://i.imgur.com/dLB968k.png an adequately trained player will often run into Keine in her beast form with the number on screen]]. Clearing the Extra Stage also gives you a Clear score of 66600000.
** Also in ''Subterranean Animism'', Parsee mocks Marisa and Alice's [[WrongGenreSavvy RPG trope discussion]] by claiming that her bridge is "Floor 666 of the Underground Skyscraper". In ''Double Spoiler'', getting pictures of the shapeshifting hellcat Rin Kaenbyou in cat form gets you a bonus of 666 points.
* ''VideoGame/JudgeDreddDreddVsDeath'': Judge Death's prisoner ID number in the load-up screen happens to be 101-100111-666.
* In the ''VideoGame/SonicDreamsCollection'' minigame "My Roommate Sonic," your cell phone only has the bottom six buttons on it, and the top row is nothing but 6's.
* ''VideoGame/KingdomRush[='=]s'' villain [[EvilSorceror Vez'Nan]] (who made a DealWithTheDevil) has this as his number motif. On Normal mode, his first form has 6666 health (which is very low for a boss), and his attack in that form deals at least 666 damage to your soldiers and heroes (which is pretty much overkill).
* The end of the train level in ''VideoGame/TheHouseOfTheDeadOverkill'' shows that the train's locomotive has has the number 666 on it.
* ''VideoGame/RuneScape[='=]s'' Lowerniel Drakan has a combat level of 666.

As a nod to this, the fans who choose not to call this move the Minus Warlock Punch instead call it the '''Satan Punch'''.
* The very dreaded, grim-reaperesque Terror Fiends in ''VideoGame/{{Miitopia}}'' have ''exacly'' 666 HP.
* In ''VideoGame/TheDarksideDetective'', one case involves spectral goings-on at the 66-6 St subway station. Lampshaded by [=McQueen=] as an appropriate place for spooky nonsense to happen.

[[folder:Web Comics]]

* ''Webcomic/QuestionableContent's'' 666th strip featured a non-canon "[[http://www.questionablecontent.net/view.php?comic=666 spontaneous metal interlude]]". Jeph Jacques had ''quite'' some fun drawing it (the strip is even titled "I've Been Waiting Three Years For This Strip).

** Had two extra strips not been added to commemorate the deaths of ''D&D'''s co-creators, ''[=OotS=]'' #666 would have featured a scene of three fiends revealing their diabolical intentions to a fourth.
* In ''Webcomic/{{Blip}}'', strip #666 features the very ominous arrival of [[http://blip.rampagenetwork.com/666/ some kind of demon-baby]].
* The author of ''Webcomic/SequentialArt'' would like to point out that he's much too mature and classy to include some arbitrary and random occult references in his [[http://www.collectedcurios.com/sequentialart.php?s=666 666-th strip]].
* ''Webcomic/AnsemRetort'' Season 7 [[http://www.ansemretort.org/ansemretort/index.html?comic=666 ended]] on this exact strip number. As did the use of Comic Sans in the comic. [[spoiler: And AR's dominance of RealityTV since Season 6, with the premiere of rival show Shibuya Shore.]]

* ''WebVideo/AMVHell Championship Edition'' was released on June 6, 2006.
* Both used and subverted in the ''Wiki/SCPFoundation''. [[http://scp-wiki.wikidot.com/scp-616 SCP-616]] is a hellish door with a strong BrownNote effect and vaguely specified "bad things" happening when it opens, but [[http://scp-wiki.wikidot.com/scp-666 SCP-666]] seems slightly more benign.
* In v4 ''Roleplay/OpenBlue'', the date of the foundation of the [[TheFederation Axifloan Coalition]] is June 6th, 1666. In v5, that day is when Princess Elizabeth of Avelia is assassinated, prompting the three largest members of the Coalition to secede and declare war on one another. Most people in-universe consider it the day the Coalition ended (even though it still exists if weakened).
* In [[http://www.youtube.com/watch?v=jR1_epbmI2g The Number 24]], a trailer spoofing ''Film/TheNumber23'', one of the professor's random associations is: "Two plus four is six. What's the number between two and four? Three. Three sixes, ''the sign of the devil!''"
* In [[WebVideo/RedLetterMedia Mr. Plinkett's]] review of ''Franchise/StarWars Episode III: Film/RevengeOfTheSith'', when he got to talk about Order 66, he pretended to be George Lucas and decided that the Kill E'm All code phrase should be "an evil-sounding number". At first he considered "666" but rejected it because he thought it was "too obvious."
* The Halloween episode of ''WebAnimation/BowsersKingdom'' was titled episode 666.
* ''[[Roleplay/GlobalGuardiansPBEMUniverse Global Guardians]]'' villain 666 is [[SuperStrength super-strong]] and NighInvulnerable, and puts on a good game of being a "demonic force for evil", but the truth is he's just a thug in a costume who uses some special effects to put the "demon" angle across to the rubes.
* The footage from LetsPlay/MarioPartyTV adds a StaggeredZoom and ScareChord whenever it appears someone is about to roll three sixes.
** It was first invoked when a player had six stars and sixty-six coins.
** [[SixIsNine This is also done when someone rolls three nines on 6's Snowflake Lake.]]

* ''WesternAnimation/AmericanDad'': When Stan is worried that his adopted grandson Nemo is the anti-christ he checks him for the mark finding a 66 but is relieved to find the next number 2 but then he sees a he has a +4 after that, cue ScareChord.
* In an ''WesternAnimation/AquaTeenHungerForce'' episode "The Cloning" the channel number that the cursed TV is playing, is channel six sixty six. Another episode included the Satanic sandwich "The Broodwich", which, among other horrifying ingredients, was, "layered with six-hundred and sixty-six separate meats from an animal which has maggots for blood!"
* In the ''WesternAnimation/{{Futurama}}'' episode "The Honking", Bender sees the binary number 0101100101 written on the wall and is unfazed, calling it "gibberish" (it's 357 with an unnecessary leading zero). Then he sees it in a mirror and realises it's 1010011010, which is 666.
* Parodied in ''WesternAnimation/CourageTheCowardlyDog'', when the characters (Except for the titular dog, who is forced to sleep outside because of the No Dogs Allowed Rule) book a room at Hotel Katz, they are given room number 666½.
* In ''WesternAnimation/{{Gargoyles}}'', the Illuminati have exactly 666 members, although you have to work it out.
* An episode of ''WesternAnimation/RockosModernLife'' ended with the character [[{{Satan}} Peaches]] playing with a paddle ball. He says, "664, 665" and then he misses and has to start all over.
** Furthermore in the episode "Hef in a Handbasket", the number to apply for Peaches' game show is "555 and THEN A BUNCH OF SIXES," the show is broadcast on channel 66, and Heffer needs to score 666 points to "win."
* ''WesternAnimation/TheSimpsons''
** The Treehouse of Horror part of one episode had Lisa and Bart going through the occult section of a library. Dewey Decimal System designation? 666. (For the curious, the [[http://en.wikipedia.org/wiki/Outline_of_Dewey_Decimal_classes actual designation]] would be 130 or 133. 666 is assigned to "ceramic and allied technologies".)
** In the opening of another Treehouse of Horror episode, a cheerful Fox Censor tells the viewers that the episode is rated TV-G, only for the ratings box to sprout an arm holding a knife and stab him, and turn to TV-PG. The stabbing continued, going to TV-14, TV-MA, TV-21, and finally, TV-666. (Which isn't a real rating, of course. The ''actual'' rating for the episode was TV-PG.)
* In the WesternAnimation/LooneyTunes short ''A Pest in the House'', hotel bellhop Daffy Duck continually disturbs a tired guest in his efforts to get some shut-eye. Guess what the unfortunate patron's room number is?
** It was probably chosen not for symbolism, but because it has a lot of "s" sounds for Daffy to lisp.
* In the first episode of ''WesternAnimation/TheBoondocks'', Huey tries to convince the guests at Ed Wuncler's garden party that UsefulNotes/RonaldReagan is the Devil by pointing out that Ronald, Wilson, and Reagan each have six letters in them. Therefore, 666. However, this just makes him look even more adorable to the guests.
** The [[ComicStrip/TheBoondocks comic strip]] had a similar joke about SantaClaus. Huey evidently went through several possible "proofs" before landing on the fact that the date of Santa's annual errand, December 24th, adds up to 36 when expressed numerically. [[InsaneTrollLogic 36 = 3 6's!]]
* ''WesternAnimation/{{Wakfu}}'':
** Episode 4 of season 1: In the flashback showing the backstory of the Ugly Princesses, there is such a long line of princes wanting to woo them that they use a "TakeANumber" device. Then comes the god Osamodas, who picks number 666 before laying a curse on the disrespectful princesses.
** In episode 9 of season 2, some of the protagonists are trapped in the Shushu world. They are forced to invoke the Rush, the favorite pastime of the Shushu, in order to avoid immediate execution. The Rush pits them against [[ZergRush 666 pyralshus]] until they fall. And to make ''sure'' they fall, Rushu also sends his [[TheDragon Dragon]] Anathar into the fray.
* The ''WesternAnimation/SouthPark'' season 1 episode "Damien" manages to sneak in a couple of visual references. At the very start of the episode, a group of number magnets on the wall have three red sixes next to each other, and the chalkboard has a sum that adds up to 666.
* In ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' episode "Wishbones", Grim says that this robe has gone through "665 washings, and it still reeks!"
* Subverted in ''WesternAnimation/StarVsTheForcesOfEvil'', where the Blood Moon Ball, which is celebrated in the underworld, takes place once every 667 years. Also, Marco's [[ItMakesSenseInContext Dragon-Motorcycle]] has "667" on its number plate. According to the creators, they wanted both cases to be played straight, but Disney wouldn't allow it.
* Amanda from ''WesternAnimation/BunsenIsABeast'' subverts this every now and then, such as when she claimed that her makeovers for her class photo cost her $667.
* In ''WesternAnimation/HotelTransylvaniaTheSeries'', episode "Buggin Out", Mavis delivers room service to a room only to realize that the card was upside down, as it was actually supposed to be delivered to room 999 (for a second you can actually see 666 on the card). In another episode, Mavis' uncle mentions room 665B.

[[folder:Real Life]]
* Scholars contend that the number in the Revelation was a code for Nero. When treated as Hebrew numbers, the letters of "Nero Caesar" add up to 616, and "Neron Kesar", the Greek version of his name, to 666.
** The scholarly theory is that Revelation is written as "prophetic allegory" -- writing a prophesy-style piece as social commentary on then-present conditions. On a similar note, there are those that believe the code stands for Gaius Caesar (which can also add up to 616) instead. Most scholars find that it's hairsplitting, however: Nero is the TropeNamer for WhileRomeBurns, and Gaius is better known by his nickname, [[TheCaligula Caligula]]. Nero is considered more likely, though, he was known for persecuting Christians whereas Caligula's reign was before the Romans considered Christianity even worth their attention.
** One theory relies on the assumption that 666 is purely symbolic, not some code: basically, the number 6 is supposed to represent man ("a human number"), because man was made on the 6th day. Also, the fact that there are ''three'' 6s is meant to stand for {{Satan}}, the Beast of the Sea, and the Beast of the Earth being an evil mockery of the Holy Trinity. This theory is total hogwash; as noted above, the number would have been written in [[http://en.wikipedia.org/wiki/Greek_numerals Greek numerals]], and the idea of "six-hundred-and-sixty-six" having anything to do with "three sixes" is a bit of a stretch (place-value notation would only have just been invented in India at the time, and it would not arrive in the Middle East until transmitted by Muslim Persian mathematicians in the 9th century).
* It was a joke in Real Life during Ronald Reagan's presidency because "Ronald Wilson Reagan" is 6 letters, 6 letters, 6 letters. (Furthermore, Ronald Reagan had his house, 666 St. Cloud Road, renumbered 668, from superstition.)
** According to conventional ''Assign-numbers-to-letters-of-the-alphabet,-add-them-up,-and-keep adding -until-you-get -a -result'' numerology, each name in the triad '''MARGARET HILDA THATCHER''' ultimately summed to '''6-6-6'''.
* A totally serious chain email in the late '90s claimed that Bill Gates was the Antichrist and that the Internet (which... [[InsaneTrollLogic he owned?]]) was his Mark, by adding up the ASCII for "Bill Gates" (66 + 73 + 76 + 71 + 65 + 84 + 69 + 83) and [[AssPull adding 3 as in William Gates ''III'']]. It went on to say this method also worked for "Windows 95", and that "WWW" represented the Number because of its resemblance to "VI VI VI".
* Speculation ran rampant the week before the 6th of June, 2006, over speculation that Armageddon would occur on 6/6/6... [[CaptainObvious It didn't.]] Maybe it was the fact that the date was actually 6/6/'''0'''6[[note]][[FridgeLogic or rather 06/06/06]][[/note]], or that if the theory held water then the [[FridgeLogic world should have already undergone divine judgement two thousand years ago]]. Creator/JonStewart called this out on ''Series/TheDailyShow'' the day before June 6 2006.
---> "Here's the thing about all the hype on the news and the marketing tie-ins, et cetera. Uh, it's not 6/6/6. It's 6/6/''0''6! It's not even 6/6/06, it's 6/''0''6/''2006''! You think God's gonna send the Four Horsemen based on a typo!? It's not happening! Forty years ago, it was 6/6/66, ''then'' you mighta had somethin' right there! ''That'' would've been the time. The only time it was really 6/6/6 was June 6 in the year 6,[[note]]A.D.[[/note]] which at the time wasn't even called 6."
* [[ImageBoard B3TA]] had a helpful announcement in 2005: "Satanists! This is the last week to conceive if you want you child born on 6/6/06!"
* Comedian/Nerd/Metalhead Brian Posehn stands 6'7, but he likes to refer to himself as 6'6.6 or "the height of the beast."
* The A666 runs from Pendlebury to Langho in [[OopNorth north-west England]] and there are many local jokes about its number. Often in conjunction with its high accident rate.
** Where it passes through the city of Bolton, the A666 is renamed ''St Peter's Way'' in the hope this either trumps 666 or cancels it out.
* U.S. Route 666, from Gallup, NM to Monticello, UT, was re-numbered US 491 in 2003, but retains the "Devil's Highway" nickname. It was the subject of various superstitions, as well as a target for sign theft. US 666 was a spur of the world-famous U.S. Route 66, but since that route was removed from existence in 1985, a numbering change was somewhat necessary, anyway.
* Another highways example. On northbound Interstate 29 just north of North Sioux City, South Dakota, there was a sign that used to read "Elk Point 6 / Sioux Falls 66." At some point in the mid-00s, the sign was changed to read "Elk Point 7 / Sioux Falls 66." Either the small town of Elk Point moved a mile to the north, or people got uncomfortable about the 666 associations and asked to have the sign changed.
* There's another theory that this was just a way to express "a large number" in roman numerals -- either DCLXVI or DCXVI, one each of several Roman numerals. Of course, this doesn't lend itself to numerologists, conspiracy theorists, televangelists or other lunatics.
* The P.O. Box address for This Is True -- who also has Get Out Of Hell Free cards to keep up -- is 666. According to the owner, he had had box number 668 for a while, then noticed 666 was free. When he inquired about it, he learned it was not to be offered to avoid people being offended. Since he specifically asked for the number, though, the post office figured it safe to give him the box.
* SF and computing journalist Creator/DavidLangford once wrote a computer program that could prove that ''any'' name [[http://www.ansible.co.uk/writing/ft107.html adds up to 666]]. You just have to assign numbers to the letters correctly (and there are hundreds, if not thousands, of ways to do that), then manipulate the numbers the right way (and there are more hundreds, if not thousands, of ways to do ''that'').
* A problem for Intel; back in the 1990s -- when computers were still running at the megahertz level -- the company would release speed increases every 33MHz (for example, all of their 400MHz-range processors would be rated for speeds clocked at 400, 433 and 466 megahertz). The number combination they would hit when they reached the 600MHz range was therefore [[CaptainObvious fairly obvious]]. When the long anticipated processor hit the market however, it was clocked not at 666MHz, but rather 667MHz. AMD also followed suit with this convention, and all subsequent processors in the hundreds of megahertz used the "number-6-7" convention.
** Not that it's still avoiding the trope, but Intel could get away with it by fudging with the numbers. The increment suggests the clock speed was divided by 3 somewhere. 2/3 is 0.6666... Which at any given point you decide to chop off how many 6's you want, you could round up the last one to 7.
* A church was "lucky" enough to get 666 as part of its phone number. They quickly changed it. On the other hand, the University of San Francisco, a Catholic medical college, had 666 as one of its proprietary prefixes throughout the '90s, mostly for dormitory rooms.
* Here's one for the oddity department: Yahoo! Sports lists athletes and assigns them an ID number in the URL. For hockey, guess who gets 666? [[http://sports.yahoo.com/nhl/players/666 Miroslav Satan]] (though it's pronounced Shuh-tan, and spelled Šatan in Slovak).
** Altough, that's how they pronounce Satan (as in the devil not the player), this goes for most Eastern European languages.
*** If you plug in athlete number 616, you get Richard Smehlik, a player for the [[http://sports.yahoo.com/nhl/players/616 New Jersey Devils]].
** Also on Yahoo! Sports, the blog Puck Daddy has a "Jersey Foul" feature highlighting the worst in homemade jerseys. They joke on how Miroslav Satan should be on the Devils with the number 6 (as it would repeat on both sleeves) when facing stuff like [[http://l.yimg.com/bt/api/res/1.2/iWd_5K82wXaT80Tc4o80sQ--/YXBwaWQ9eW5ld3M7cT04NTt3PTYzMA--/http://media.zenfs.com/en/blogs/sptusnhlexperts/SCOTT-BENNIE_FLAMES.jpg this]].
* There's an urban legend among fundamentalist Christian conspiracy theorists that the UN General Assembly and/or the European Parliament chambers have a seat number 666 that is never occupied and is presumably being reserved for their [[TheAntichrist boss]] when he turns up. This is, of course, not the case; the [[http://coc.dgacm.org/ga67.htm UN General Assembly seats]] are assigned in alphabetical order by nation, and are not numbered, while seat #666 in the EU Parliament chambers in Strasbourg and Brussels were, around [[http://www.europarl.europa.eu/sed/hemicycle.do January 2014]], occupied by Verónica Lope Fontagne of Spain and Eva Lichtenberger of Austria, respectively.
* Creator/TheABC's Canberra radio station is numbered 666. Being that the ABC is government-funded, EpilepticTrees ensued.
* Interestingly, if the number is actually 616 and not 666, several places have been afraid of the wrong number all along. Examples include: The USA, who changed highway 666 to highway 491 in 2003, and most especially the Moscow transport department, who changed the 666 bus route [[HilariousInHindsight to... 616.]]
* The first [[UsefulNotes/AppleMacintosh Apple]] computer ([[ExactlyWhatItSaysOnTheTin the Apple I]]) went on sale in July 1976 at the price of $666.66. This was due mostly to a collection of mundane coincidences: Steve Jobs setting the price at $500 (plus a 1/3rd markup), because Steve Wozniak "liked repeating digits" and both Steves' general ignorance of the significance of the number.[[note]] This was before the Internet.[[/note]]
* Similar to the usual omission of a thirteenth floor (as well as the [[FourIsDeath fourth]] in East Asian-dominated cultures), many larger hotels have no room 666 for superstitious reasons.
* As Website/NotAlwaysRight records, superstitious customers may become a bit alarmed if their purchase or change totals $6.66, and some add more items to their order to avoid it. For instance, [[http://notalwaysright.com/sinfully-delicious-part-2/11299 here]] and [[http://notalwaysright.com/armageddon-shopping-list-holy-water-crucifix-tic-tac/827 here]].
* A bill in the California Assembly would return red-light cameras to many cities and make the resulting tickets well-nigh-unfightable "administrative fines" rather than the current punitive fines which can be challenged in court. Opponents have lost no time in remarking that the bill is AB666.
* Creator/TheCriterionCollection numbers its hundreds of famed films in the order that they enter the collection and decided to have fun with this trope when they reached 666 in 2013 -- they assigned it to ''Film/TheDevilsBackbone''!
* There is at least one case of an atheistic man who was tired of evangelists calling his house phone, so he requested the first three digits to be 666.
* A Qatari man bought the phone number 1(666)666-6666 for 10 million riyals (about $1.5 million), as Jewish and Muslim tradition believe the number to be holy. The Jews, because the number 6 represents the six directions (forward, backward, up, down, left, right), and the Muslims because they associate it with the Arabic word "ellah," (itself reminiscent of 'allah'). Seen [[http://www.theregister.co.uk/2006/05/23/mobile_number_sold/ here.]]
* During the Falklands War of 1982, the British expeditionary force was given the field post office number BFPO 666. The British Army Chaplaincy Department, along with its colleagues in the Royal Navy and RAF, protested mightily. British soldiers considered it both a huge joke and a licence to bring seven different sorts of Hell down on the Argentinians.
* June 16th, 1943, a single B-17E Bomber was flying a mapping mission over the Solomon Islands. It's tail number? 41-2''666'', nicknamed "Old 666". At 7:40, with only 22 minutes left, Old 666 was attacked by 15 [=A6M=] Zeroes and 2 Ki-46 Dinahs. Old 666 proceeded to [[CrowningMomentOfAwesome fight them off until they ran out of fuel and ammo, shooting quite a few down in the process]] and completed the mapping mission. June 16th is shown as 6/16, meaning this got ''both'' versions of the number.
* There's an UrbanLegend going around that suggests that Monster Energy drink is funded by Satanists, since the people peddling the legend interpret their symbol as three Hebrew sixes. As mentioned above, even if they were correct about the symbol three sixes is not six hundred and sixty six.
* The ecodesign regulation of the european commission, which outlaws certain types of vacuum cleaners (and is a frequent target for eu critics, especially in germany), is the Regulation 666/2013. ( http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32013R0666 )
* At Devil's Lake State Park near Baraboo, Wisconsin, there's a very long staircase on the East Bluff named the Devil's Staircase. This troper decided to count the number of stairs on said staircase. Give or take (there were some steps that might qualify as stairs, but might not), the number of stairs is 666.
* In Canada, dialing *666 on cellphone connects you to [[https://www.tc.gc.ca/eng/canutec/menu.htm CANUTEC]], Transport Canada's emergency response center. Appropriately, they deal with toxic and explosive chemicals, which can be pretty hellish.
* In 1988, nuclear engineer Robert W. Faid wrote a book entitled ''[[http://www.deuceofclubs.com/books/086gormbachov.htm Gorbachev! Has the Real Antichrist Come?]]'' Among other prophecies of the Antichrist [[EpilepticTrees supposedly fulfilled]] by [[UsefulNotes/MikhailGorbachev the Soviet leader]], Faid observed that the letters of "Gorbachev" transliterated into Greek added up to... [[AvertedTrope 888]], the number of Christ, and therefore Mikhail Gorbachev must be the false Christ. That is, if you transliterate it as "Gormbacob", [[InsaneTrollLogic with an m]]. Naturally, this theory was blown to smithereens by TheGreatPoliticsMessUp.
