History Main / ArcNumber

* The number 1138 pops up a lot in Creator/GeorgeLucas' work, as a tribute to his first film, ''Film/{{THX 1138}}''. As does 327, for reasons unknown. Franchise/StarWarsLegends adds a third: 1977, the year the original movie was released.

* ''ComicBook/EightBillionGenies'' uses '''8''' as an arc number in a meta sense -- the story tracks the effects of the genies in multiples of eight. Eight seconds, eight minutes, eight hours, eight days, and so on. The series is eight issues long.

* The ''VideoGame/FiveNightsAtFreddys'' franchise has the number 1987, referring to an... incident that happens in the timeline.

*** ''Literature/YumiAndTheNightmarePainter'': Virtuosity seems to have been associated with the number thirteen: there are a lot of thirteens in Yumi's rituals, while a nightmare requires thirteen feedings to achieve full stability, and there are thirteen yoki-hijo plus Yumi.

* ''Literature/TheCosmere'':

*** Cultivation, otoh, seems to be associated with threes. 3 Gods, 3 Bondsmiths, 3 personal interventions (Lift, Dalanar, Tarvargian.) Each of the 16 original shards appears to have their own number associated.

** ''WesternAnimation/SpiderManIntoTheSpiderVerse'': 42 is the lottery number that got Miles into the school,
42 is the number present on the spider that bit him, 2 numbers that spell out 42 are present after Miles falls off a building, and 4+2 makes 6, the number of main Spider-People we see as part of the Spider-Gang. [[https://www.insider.com/spider-man-spider-verse-42-meaning-2019-2 According to the director]], it's a reference to UsefulNotes/JackieRobinson, "a barrier-smashing black superhero" like Miles.

* 42 appears a lot in ''WesternAnimation/SpiderManIntoTheSpiderVerse''. [[https://www.insider.com/spider-man-spider-verse-42-meaning-2019-2 According to the director]], it's a reference to UsefulNotes/JackieRobinson, "a barrier-smashing black superhero" like Miles.

* Series/{{Arrowverse}}:
** Much like the comics, ''Series/{{Arrow}}'' and ''Series/{{The Flash|2014}}'' tend to feature the number 52 rather frequently. Just like the comics, it referenced the number of Alternate Earths... [[Series/CrisisOnEarthX barring one]].

* [[https://tvtropes.org/pmwiki/pmwiki.php/Franchise/Kirby Kirby]] has 86, as it is the GoroawaseNumber for Creator/HAL.

* In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', the number four revolves around the Champions, most likely to invoke FourIsDeath and the past's tragedy regarding them. There are four major non-Hylian races with major quest arcs, four dead Champions, each from the four races and four Divine Beasts once plioted by the Champions. The Champions represent the four weapon types in the game. There are four Blights corrupting the Divine Beasts and four powers to be gained from the Champions' freed spirits.
** Even the runes and upgrades rely on fours. There are four main rune shrines at the beginning of the game. There are four Great Fairies to upgrade armor and clothing up to four times. The Goddess Hylia statues's price for health or stamina is four spirit orbs.

* The number 12 is everywhere in ''Anime/JuniTaisenZodiacWar'': The War happens every twelve years (on December 12th, no less), there are twelve participants, twelve Beast Gems to collect, and twelve hours to win it all before the poison in their bodies kills them. Even this year's host is named Duodecuple (12 in Latin).

* The number 12 is prevalent in ''LightNovel/{{Katanagatari}}''. There are twelve swords. The story takes place roughly over twelve months and comprises twelve episodes/volumes. Also, there are twelve Maniwani leaders and twelve Shogunate guards.

* In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', the number four revolves around the Champions, most likely to invoke FourIsDeath and the past's tragedy regarding them. There are four non-Hylian races, four dead Champions, each from the four races and four Divine Beasts once plioted by the Champions. The Champions represent the four weapon types in the game. There are four Blights corrupting the Divine Beasts and four powers to be gained from the Champions' freed spirits.

* ''Film/{{Holocaust 2000}}'' has the Number of TheAntichrist, 30.397368 = 2√231, which looks like "IESVS" spelled upside-down.

* 2-1-6 is important in ''VideoGame/{{Fallout 3}}''.

** Vaults [[{{Room 101}} 101]] and 108, the latter of which is also half of 216.

* ''WesternAnimation/TheFairlyOddParents'': Virtually all major events in the fairies' lives, such as Cosmo's birth, Wanda Meeting Cosmo, both becoming fairy godparents for the first time, etc. all happened exactly 10,000 years ago. As mind-boggling as it sounds, the fact that Wanda once said fairies have terrible memories makes these claims to the time of the events as unreliable.
* ''WesternAnimation/YoungJustice2010'':
** The series is set on Earth-16 of the [[Creator/DCComics DC]] {{Multiverse}}, with 16-year-old Aqualad as its leader. Superboy and Miss Martian are aliens that are roughly equivalent to 16-year-old humans, with Superboy being a clone grown for 16 weeks prior to the first episode. Wally has his sixteenth birthday towards the end of the first season. Time stamps are often at 16 minutes or 16 hours. The second season is set in the year 2016, and its first episode begins at 16:00.

* The number 87 appears mulitple times throughout ''WesternAnimation/DuckTales2017'', whether it's DT-87, the [=McDuck=] Manor security system, or 87 cents that was stolen from Scrooge's money bin one day. This is a reference to when the original ''[=DuckTales=]'' series premiered in 1987. [[spoiler:Webby is also known as experiment 87, code-named April, created by F.O.W.L. using Scrooge's DNA]].

* In ''Literature/TheHungerGames'', 12. 12 districts, 24 tributes (who become eligible at age 12), training scores of up to 12, 12 arrows in the quiver in the arena, 12 houses in the Victor's Village, 24 [[spoiler: wedding]] dresses designed for Katniss, then voted down to 6, and lightning strikes at midnight and noon in a certain section of the [[spoiler: Quarter Quell arena]], which later becomes important to the plot. Also, in the first book, Prim and Rue were 12 years old, and Rue was one of 6 siblings. And of course, the main characters are from District 12.

** ''VisualNovel/ZeroTimeDilemma'' continues the trend. There are nine people who were living in Dcom and were abducted, as well as [[spoiler:nine bodies for the robotic ''tenth'' player, Sean 729. Note that 729 = 9x9x9, referencing the triple nines of the first title.]] The AB Game makes a brief reappearance, and again the goal is to reach 9 points, though the fact that it's only for one section means the point values increase to allow it to occur with a single betrayal.
*** However, 10 also proves to be a recurring number. There are ten doors in the Monty Hall problem, [[spoiler:ten total players]], ten total lives trapped down in the shelter thanks to the presence of TeamPet Gab, [[spoiler:and the escape door has an X, the Roman numeral for 10. Also, it's not a Nonary Game this time, it's the '''Deci'''sion Game]].

* ''WebAnimation/BattleForDreamIsland'' has 2763, a number often used for how many times something has happened, the distance it will take to get somewhere, or other purposes. WordOfGod confirms that this is because of the amount of offspring within Cary and Michael Huang's family per generation. Specifically, Cary and Michael make two, their father is one of seven siblings, the father's father is one of six siblings, and that father is one of three siblings.
** Played with in episode 5 of TPOT, which instead uses the number 2762, which Coiny justifies as not everything always being the same distance away.

*** However, 10 also proves to be a recurring number. There are ten doors in the Monty Hall problem, [[spoiler:ten total players]], ten total lives trapped down in the shelter thanks to the presence of TeamPet Gab, [[spoiler:and the escape door has an X, the Roman numeral for 10.]]

* ''TabletopGame/{{Eberron}}'': 12+ 1, a Baker's dozen. The guy who designed ''TabletopGame/{{Eberron}}'' is named Keith Baker, although by WordOfGod he didn't realise the "Baker's dozen" connection until the setting was already nearly done. There are lots of examples where you get 12 obvious things and a 13th hidden one. 12 dragonmarked houses -- and the eradicated (apart from one lich, who can't use it, and some non-canonical novels) 13th dragonmark of Death. 12 Planes -- and the sealed 13th Plane of [[CosmicHorrorStory Xoriat]]. 12 moons -- plus the 13th dark moon, which disappeared with the sealing of the 13th plane. 12 nations in the Khorvaire continent, plus Cyre... the 13th nation, which is now the D&D equivalent of Fallout. It was made especially blatant in "Faiths of Eberron", which states that the Silver Flame celebrates 13 holidays, including one that seems to have nothing to do with anything and is just about eating pastries, and which is on its way out. The name of the fading holiday? Baker's Night.

* ''Series/TheLordOfTheRingsTheRingsOfPower'': Number 3. Season 1 presents 3 candidates who could be Sauron in disguise: [[spoiler:Adar, the Stranger and Halbrand]], there are the 3 priestesses of Sauron from Rhun, and the first 3 rings of power that are made at the end of the season, Narya, Nenya and Vilya.

* 5 in ''TabletopGame/MagicTheGathering''. There's a reason: There are 5 colors of magic, each with 2 enemies and 2 allies [[SigilSpam (as illustrated on the card backs)]] so the creators often do the same thing with a variation for each color.
