History Main / NumericalThemeNaming

** ''Series/KamenRiderRevice'' has the Igarashi siblings named in order of birth: Ikki ('''1st'''), Daiji ('''2nd'''), and Sakura ('''3rd''').

** ''Series/KamenRiderZiO'' plays this straight with Zi-O and his upgraded forms. Zi-O Decade Armor ('''1'''0), Zi-O II ('''2'''), Zi-O Trinity ('''3'''), and [[spoiler:Grand Zi-O from Grand Slam]]('''4''').

* ''Manga/GohanNoOtomo'' features a pair of siblings named ''Ichi''ta (one) and ''Ni''ko (two).

** [[spoiler: Their newest addition also holds true to this trend: the '''fourth''' user, Hikage '''Shin'''omori, and '''fifth''' user, Dai'''go'''ro Banjo.]]

* ''Manga/TheFoxAndLittleTanuki: Both Senzou's (the fox) and Manpachi's (the tanuki) names use older kanji for specific numbers. The "sen" in Senzou's means "thousand", while the "man" in Manpachi's means "ten thousand" which Koyuki suggested be incorporated into his name since Manpachi is "coming after" Senzou as his underling. Additionally, the "pachi" in Manpachi's name means "eight" which is a number often associated with tanuki. Senzou's "follower" Momoji even gets in on it; "momo" means "hundred" in his case.

* In the book ''Merlin's Mistake'' one of the protagonists is named Tertius. His two brothers are named Primus and Secundus. It is mentioned their father wasn't very creative.
* In Creator/JRRTolkien's legendarium, the first three Elves to awake were called Imin, Tata and Enel, that is One, Two, and Three. Much later, we have Nelyafinwë, that is, Third Finwë (after his grandfather Finwë and his father Curufinwë...quite possibly in an attempt by said father to spite his own brother, yet another Finwë.)
** It is assumed Celebrimbor's father name is Nelyacurufinwe ("Third Skillful Finwe") ... after his grandfather Curufinwe Fëanaro (Feanor) and father Curufinwe Atarinkë (Curufin). So his whole name in Quenya would be Tyelperinquar Nelyacurufinwe Curufinwion.

* In the ''Literature/{{Remnants}}'' series, the Blue Meanies / the Children are all named by the system (Number) (Positive adjective) (Geographic feature), e.g., "Four Sacred Streams," "One Divine Mountain."
** In the Literature/{{Discworld}} [[ImperialChina Agatean]] [[FantasyCounterpartCulture names]] also work like this.

* In ''Literature/SeptimusHeap'' the titular character is the [[MagicalSeventhSon seventh son of a seventh son]].
* Septimus and Octavia of ''[[Literature/NightLords The Covenant]]'' ''[[TabletopGame/{{Warhammer 40000}} of Blood]]'', are somewhere between this and YouAreNumberSix mixed with MeaningfulRename. Their master renames all his slaves with ordinal High Gothic names. When he charged into a stronghold of his enemies to save Octavia from her abductors, she accepted the change from Eurydice. Maruc, Septimus' assistant, is trying valiantly to avoid becoming Nonus in the eyes of his masters.
* In Creator/NeilGaiman's ''Literature/{{Stardust}}'', the King of Stormhold followed the ancient Roman method in the naming of his sons: Primus, Secundus, Tertius, Quartus, Quintus, Sextus, and Septimus. There's a daughter named Una, too. Had there been more daughters, they'd surely follow a similiar trend.
* In Creator/JohnCWright's ''Literature/ChroniclesOfChaos'', the children were originally named Primus, Secunda, etc. When they are told to chose names, Quentin decides that he's fine as he is.

* In Creator/AaronDembskiBowden's Literature/NightLords series, [[VillainProtagonist Talos]], like most other Night Lords, takes captives for the purpose of [[MadeASlave enslaving them]]. Unlike most of their slaves, Talos takes slaves that are particularly useful as his personal slaves rather than to serve on their ship. His slaves are renamed, presumably after High Gothic numerals, starting with Primus, then Secundus, and so on. The current slaves he holds in the story are [[BadassNormal Septimus]] and [[FishOutOfWater Octavia]][[note]]Seven and Eight[[/note]], and later another slave, [[ActionSurvivor Maruc]] is taken. While he would have been number 9, only Talos' best friend and squadmate [[AffablyEvil Cyrion]] refers to him as "Nonus", and on only the one occasion where a member of [[TheSquad First Claw]] calls him by name "onscreen" after his capture.
* In ''Literature/TheWonderfulAdventuresOfNils'', the wild geese that the protagonist travels with are named Yksi, Kaksi, Kolme, Neljä, Viisi and Kuusi - which are simply the numbers between one and six in Finnish.

* [[ArtificialHuman Seth]], from ''VideoGame/StreetFighterIV'', has the codename I-5; the number '5' is equivalent to the roman numeral 'V', thus, Seth's "number" is related to the game he first appears in.
* In ''Videogame/{{Earthbound}}'', the towns are named Onett, Twoson, Threed, and Fourside. Likely unintentional, but adding those four numbers together gives you 10, which is funny considering that the game was on the Super Nin'''ten'''do
* The Legendary ''Franchise/{{Pokemon}}'' Artic'''uno''', Zap'''dos''' and Mol'''tres'''.[[note]]The first three numbers in Spanish.[[/note]]
** And in ''VideoGame/PokemonBlackAndWhite'', we have D'''ein'''o, '''Zwei'''lous, and Hy'''drei'''gon, which are one headed, two headed, and three-headed dragons respectively. [[note]]The first three numbers in German.[[/note]]
** ''VideoGame/PokemonXAndY'' introduces H'''one'''dge (a possessed sword) and '''Doubl'''ad'''e''' (two possessed swords).
** In non-legendaries, Doduo and Dodrio.
** Would Mew and its clone Mewtwo count?
** There's also Dug'''trio''', which is composed of three Digletts.
* ''VideoGame/ChronoCross'' has a mixture of Latin and Spanish numbers for the Vita boss: Vita Unus, Vita Dos, and Vita Tres. Yes, we are aware that Vita Unus is not proper grammar.
* Gehn, villain of the second ''Videogame/{{Myst}}'' game, ''VideoGame/{{Riven}}'', and one of the novelisations, numbers everything he has control of, most notably his Ages, [[YouAreNumberSix and the people in them]]. Because Riven is his Fifth age, much of his property within it has that number on it somewhere.
* {{Terraform}}er ships in ''[[VideoGame/{{X}} X3: Terran Conflict]]'' and ''Albion Prelude'' are given a four-letter designation that proves to be a number in base 16. Some examples: #deca (57,034 in base 10), #fade (64,222), #cafe (51,966).
* ''VideoGame/PennyArcadeAdventures'': The Academic Symposium has a quartet of scientists named Dr. Uno, Dr. Twee, Dr. Drei and Dr. Quatromain [[note]]Spanish, Dutch, German and Portuguese(kinda) for One, Two, Three and Four, respectively.[[/note]]. A later sidequest involves getting all the Symposium's attendees to sign a petition, and because of the various grudges, rivalries and prejudices they have for one another, they need to be approached in a certain order. Guess what it is. [[spoiler:The catch is that the numbers are somewhat of a RedHerring; while ''those specific'' scientists must be spoken to in the order their names suggest, there are two other scientists whose names don't fit the convention and one of them must sign between Uno and Twee to get the proper order.]]
* ''VideoGame/FinalFantasyType0'': The members of Class Zero have names related to cards in a deck, resulting in numerical naming - Ace, Deuce, Trey, Cater, Cinque, Sice, Seven, Eight, Nine, Tiz (Hungarian for ten), Jack, Queen, King, and Joker.

* A sidequest in ''VideoGame/Borderlands2'' features a quartet of assassins named Oney, Wot, Reeth, and Rouf.
* Most major characters in ''VideoGame/Drakengard3'' are named after numbers. The intoner sisters run from One to Five, with our heroine [[MyHeroZero Zero]] being their older sister [[spoiler:and PatientZero of the evil flower on her eye]]. Two to Five have Disciples whose name are non-English numbers: Two's Cent (hundred), Three's Octa (eight), Four's Decadus (ten) and Five's Ditto (close enough to Duo: two).
* In ''Franchise/TouhouProject'', side character Hieda no Akyuu is a one-person version of this, being a person who dies and {{Reincarnat|ion}}es every ten to twenty years but retains her PhotographicMemory of every life. A'''kyuu''' is the ninth reincarnation; for bonus points, her original incarnation was the RealLife historian [[https://en.wikipedia.org/wiki/Hieda_no_Are Hieda no Are]], whose name can be seen as representing zero[[note]]Though the real Are's name is written with entirely different kanji[[/note]].

* The ''VideoGame/DukeNukem'' games use a numerical theme naming for their main games: ''[[VideoGame/DukeNukemI Duke Nukem]]'' '''''[[VideoGame/DukeNukemI I]]''''', ''[[VideoGame/DukeNukemII Duke Nukem]]'' '''''[[VideoGame/DukeNukemII II]]''''', ''[[VideoGame/DukeNukem3D Duke Nukem]]'' '''''[[VideoGame/DukeNukem3D 3]]'''''''[[VideoGame/DukeNukem3D D]]'', and ''[[VideoGame/DukeNukemForever Duke Nukem]]'' '''''[[VideoGame/DukeNukemForever For]]'''''''[[VideoGame/DukeNukemForever ever]]''.

* ''VideoGame/Idolish7'' All of the [=IDOLiSH7=] and TRIGGER members incorporate 1-7 and 8-10 in their names, respectively.

* Tetras, from ''Webcomic/TheMotleyTwo''. Obsessed with the number four, has a fitting name (the prefix tetra-).

* In ''Literature/{{Hyouka}}'', four of the prestigious families in Kamiyama are '''Juu'''monji (10), '''Saru'''suberi (100), '''Chi'''tanda (1000), and '''Man'''ninbashi (10000), and Satoshi unofficially grouped them as "Exponential Four Clans".

** [[spoiler: Their newest addition also holds true to this trend: the '''fifth''' user, Dai'''go'''ro Banjo.]]

* The ''VideoGame/DukeNukem'' games use a numerical theme naming for their main games: ''[[VideoGame/DukeNukemI Duke Nukem]] '''[[VideoGame/DukeNukemI I]]''''', ''[[VideoGame/DukeNukemII Duke Nukem]] '''[[VideoGame/DukeNukemII II]]''''', ''[[VideoGame/DukeNukem3D Duke Nukem]] '''[[VideoGame/DukeNukem3D 3]]'''[[VideoGame/DukeNukem3D D]]'', and ''[[VideoGame/DukeNukemForever Duke Nukem]] '''[[VideoGame/DukeNukemForever For]]'''[[VideoGame/DukeNukemForever ever]]''.

* The ''VideoGame/DukeNukem'' games use a numerical theme naming for their main games: ''Duke Nukem '''I''''', ''Duke Nukem '''II''''', ''Duke Nukem '''3'''D'', and ''Duke Nukem '''For'''ever''.

* The ''Franchise/DukeNukem'' games use a numerical theme naming for their main games: ''Duke Nukem '''I''''', ''Duke Nukem '''II''''', ''Duke Nukem '''3'''D'', and ''Duke Nukem '''For'''ever''.

* In ''FranchiseTouhouProject'', side character Hieda no Akyuu is a one-person version of this, being a person who dies and {{Reincarnat|ion}}es every ten to twenty years but retains her PhotographicMemory of every life. A'''kyuu''' is the ninth reincarnation; for bonus points, her original incarnation was the RealLife historian [[https://en.wikipedia.org/wiki/Hieda_no_Are Hieda no Are]], whose name can be seen as representing zero[[note]]Though the real Are's name is written with entirely different kanji[[/note]].

* In ''Manga/KatekyoHitmanReborn'' almost every character has a number that corresponds to their name. For example Gokudera is 59 (Go=5, Ku=9). Some other examples include Tsuna (27), Yamamoto (80), and Hibari (18).

* ''Manga/MahouSenseiNegima'' has Averruncus series: [[PosthumousCharacter Primum]], [[PsychoElectro Secundum]], [[AntiVillain Tertium]], [[AxCrazy Quartum]], [[FauxAffablyEvil Quintum]] and [[TokenGirl Sextum]]. [[PlayingWithFire Nii]] and [[AnIcePerson Septendecim]] similarly fit.
* In ''Anime/MaiHiME'', Yuuichi's name contains the kanji for "one". The other kendo club members' given names, as seen on nametags in episode 2, are Tamaji, Kouzou, Shirou and Gosaku -- containing the kanji for "two", "three", "four" and "five" respectively.

* In ''VideoGame/{{Touhou}}'', side character Hieda no Akyuu is a one-person version of this, being a person who dies and [[{{Reincarnation}} reincarnates]] every ten to twenty years but retains her PhotographicMemory of every life. A'''kyuu''' is the ninth reincarnation; for bonus points, her original incarnation was the RealLife historian [[https://en.wikipedia.org/wiki/Hieda_no_Are Hieda no Are]], whose name can be seen as representing zero[[note]]Though the real Are's name is written with entirely different kanji[[/note]].

--> '''Usopp''': "[[LampshadeHanging Shouldn't it be Goka?!]]"

* A minor character in ''LightNovel/OokamiSan'' is modeled after Snow White, with the seven dwarfs represented by her seven younger siblings, all with this naming convention.

[[folder:Film]]
* A Filipino film, ''Ang Tanging Ina'' has a mother of 12 name her children as thus: Juan, Ger'''tu'''dis, Dimi'''tri''', '''Por'''cia, Pip, '''Six'''to, '''Seve(n''')rina, Cate, Shammy ('siyam' being Filipino for nine), Ten-ten, and two unnamed baby twins.
* ''Film/TheMatrix'' includes characters Cypher (zero), the One, Switch (two), Trinity (three), and Dozer (twelve).
* ''Film/{{Ran}}'' has the three sons of Lord Hidetora, named (in somewhat typical Japanese fashion) Tarō, Jirō (second son), and Saburō (third son).

[[folder:Web Original]]
* Tetras, from ''Webcomic/TheMotleyTwo''. Obsessed with the number four, has a fitting name (the prefix tetra-).

** Japan has a similar scheme available for male given names; Ichirō ("One" + "Son"), "Jirō" ("Two") Saburō ("Three"), and so forth.[[/note]]''Film/{{Ran}}'' in Film above is a particularly famous fictional example, albeit with "Tarō" substituted for Ichirō[[/note]] A DeadHorseTrope was to have Asian stereotype characters use a BlindIdiotTranslation and refer to "Number-one Son".

** Girls Witokape, Hapan, Hepistanna, Wanska, Wihake, Hakata, Cekpa

** Another large city where the numbered naming is in full display is UsefulNotes/{{Philadelphia}}. The numbered streets are numbered west from Front Street (which takes the place of a "1st Street"), which is (or was, at any rate)[[note]]Reclamation and other things have meant that some streets, etc., have been built closer to the river[[/note]] on the waterfront of the Delaware, running parallel to its course in Center City (that's downtown). The major exception to this rule is Broad Street, which would be 14th Street but it was designated by William Penn as marking the main north-south artery through the city. Because the river bends fairly sharply eastward a little bit north of Center City, Front Street (which just keeps going in a straight line) gets pretty far from the waterfront in North Philly; in some areas, they have [[AlphabeticalThemeNaming lettered streets]] going eastward from Front Street. (Streets perpendicular to the numbered ones in Philadelphia are largely named after [[FloralThemeNaming trees and plants]] in Center City, with names after what appear to be people but also other random things outside Center City, e.g., one substantial area in the northern part of the city where it's all [[LocationThemeNaming Pennsylvania counties]].)

** UsefulNotes/{{Chicago}}, with its large-scale street grid, still uses numbers for almost all east-west streets on the South Side. (Near the center axis, a presidential naming scheme takes priority; Roosevelt Road, Cermak Road and Pershing Road are 20th-century rebrands of 12th, 22nd and 39th Streets.) Many of the north-south avenues on the West Side were originally assigned numbers as well; they have all been renamed by the city, but the avenue numbers persist in street addresses and in a few western suburbs.

** Japan has a similar scheme available for male given names; Ichirō ("One" + "Son"), "Jirō" ("Two") Saburō ("Three"), and so forth. A DeadHorseTrope was to have Asian stereotype characters use a BlindIdiotTranslation and refer to "Number-one Son".

** It is assumed Celebrimbor's father name is Nelyacurufinwe ("Third Skillful Finwe") ... after his grandfather Curufinwe Fëanaro (Feanor) and father Curufinwe Atarinkë (Curufin). So his whole name in Quenya would be Telperinquar Nelyacurufinwe Curufinwion.

* The Nerdlucks in ''Film/SpaceJam'' are an unusual case of this trope, all named after the same number. That number is zero: Nil, Nada, Zilch, Zip, and Bupkus.[[note]]Bupkus is named after "bupkis," Yiddish for "nothing."[[/note]]

* ''Manga/JojosBizarreAdventure'':

Note that this only applies to proper names. For one who is given a number instead of a name, see YouAreNumberSix. For a more specific sort of numerical theme naming, see OneTwoThreeFourGo, SevenIsNana and GoroawaseNumber.
