Theme Twin Naming

Carly: If you did have a twin brother, why would his name need to sound similar to yours?

When twins appear in fiction, it's very likely that they will be named to sound like a matched set. Common options are rhyming names (Tyler and Skyler); alliterative names (Michael and Mitchell); thematic names (Dawn and Eve); or anagrams (Amy and May). Bonus points if the twins have dissimilar full names but usually go by nicknames which fit this trope, like Phil and Lil (full names Philip and Lillian) from Rugrats.

If the twins are often referred to as one individual (e.g. "Jim" and "Tim" are almost always called "Jim-and-Tim" in conversation) this is even more likely, so it's understandably very common with Single-Minded Twins.

Also, a character's Evil Twin will often have the same name as the character, only reversed, e.g. the evil twin of Alfred will be named Derfla. Of course, if the character's name is something like Bob, this leads to some confusion.

In Japanese and other syllable-based languages this is especially common, because twins often end up sharing either the first or the final characters of their names. Most definitely Truth in Television.

Like most twin tropes, this annoys the hell out of many real-life twins. Child psychologists even advise parents against the practice, since it can impede the children's development as individuals.

A subtrope of Family Theme Naming.

     Anime and Manga  

  • Kyon of Haruhi Suzumiya calls Mikuru's fake twin "Michiru", playing off this trope.
  • From the anime W~Wish, there's twin siblings Junna and Senna.
  • Appears in several CLAMP works:
    • Sisters Tarta and Tatra from Magic Knight Rayearth.
    • Fraternal Half-Identical Twins Hokuto and Subaru of Tokyo Babylon and X1999 are both named after constellations of seven stars. Subaru (昴) is Pleiades, while Hokuto (北都) means The Big Dipper. The seven stars theme is quite significant in X.
    • Cho Li and To Li from Miyuki-chan in Wonderland (themselves analogs to Tweedledee and Tweedledum).
    • In Chobits, Freya and Elda/Urda are named after Norse Goddesses.
    • CLAMP appears to have restrained themselves with the twins Fay and Yuui of Tsubasa Reservoir Chronicle, however, since their names have no apparent meaning and may have been intended to simply sound foreign to Japanese readers.
    • Maru and Moro of ×××HOLiC, whose full names are Marudashi and Morodashi (meaning "flashing" and "streaking", Yuuko has an odd sense of humor).
  • Suiseiseki and Souseiseki of Rozen Maiden ("Jade" and "Lapis Lazuli" respectively, also matching up to their dress colors).
  • Sakon and Ukon of Naruto take this a bit further than most — they actually share the same body, and the first kanji in their names mean "left" and "right" respectively. Also, Hinata and Neji's fathers are twins: Hiashi and Hizashi, which mean "daytime" and "sunlight" respectively, and both contain the kanji for "sun" like most Hyuga family members.
  • Ranma ˝ had Chinese Girl twins Pin-Ke and Lin-Ke (Pink and Link in some translations) and (anime-only) separate characters Rinrin and Ranran (Ling-Ling and Lung-Lung in the translation).
  • Mermaid Melody Pichi Pichi Pitch had Kaito and Gackto, both named after popular singers. The anime changed Gackto's name to Gaito in order to play up the connection to Kaito, or maybe just to play down the fact that Gackto has more in common with his namesake than that. There's also the Black Beauty Sisters, Mimi and Sheshe, although "sisters" is just a stage name (possibly so they could get away with public displays of affection in the seven-AM programming block). Although being a pair of enchanted anglerfish, they probably are sisters. The other pair of twins in the series, Caren and Noel, do not match.
  • Digimon Tamers has Ai and Makoto, meaning "Love and Truth" respectively, as well as being the title of a popular book.
    • Likewise, Digimon Frontier had Kouichi and Kouji - "First Radiance" and "Second Radiance".
  • Tiff and Tuff in Kirby: Right Back at Ya!. This does not match in the original, as their names were Fumu and Bun, respectively.
  • Momiji and Kaede of Blue Seed are both named after words for "Maple".
    • In Harukanaru Toki No Naka De, the story about Nue has him followed around by two deers whom he calls Momiji and Kaede. Whether it's a Shout-Out to Blue Seed or just a coincidence is unclear (the maple imagery in general does make a few other appearances in the Haruka franchise, along with the more traditional Cherry Blossoms).
  • Kyou and Ryou of CLANNAD both have Tomboyish Names that rhyme.
  • Yuna and Yuma Kashiwagi in Pani Poni Dash!.
  • Kirio and Kirika of Kamichama Karin. It's also worth noting that their father's name is Kirihiko.
    • Kazune and Kazusa Kujyou, though Kazusa is more of a opposite sex clone than a twin, and their father Kazuto.
  • Darry and Gimmy (puns on hidari and migi, Japanese for left and right, respectively) in Tengen Toppa Gurren Lagann.
  • Fuuka and Fumika Narutaki in Mahou Sensei Negima!. Less obvious in translation, as the former's name is usually Anglicized as "Fuka".
  • In Rurouni Kenshin's Kyoto arc, we learn that Cool Big Sis Tae Sekihara has a twin sister named Sae.
  • The Half-Identical Twins in Kiddy Grade are named Tweedledum and Tweedledee (see Literature section above). There are also two bishonen Sinistra and Dextera ("left" and "right" in Latin), who are not actually twins but look very much alike.
  • Kidou Tenshi Angelic Layer has sisters Shōko and Shūko, although they, too, are not twins — Shuuko is older. This was lampshaded by their English voice actresses in the audio commentary, who wondered what kind of cruel parents their characters had.
  • A variation occurs in Fushigi Yuugi. While Amiboshi and Suboshi are known by their Seishi names and not their real ones, it is still worth noting that their Seishi names sound alike. Miboshi, however, is another story...
  • The Tachibana twins in Captain Tsubasa are named Masao and Kazuo.
  • The Dylandy twin brothers in Gundam 00. The older twin is Neil, whose name means "cloud"; the younger twin is Lyle, and his name means "island". In a twist, they share the same Code Name in Celestial Being: Lockon Stratos.
  • Sarasa's and her twin Tatara's name from Basara sound rather similar.
  • Tatsuya and Kazuya from Touch. Taking it a step further, they are nicknamed Tacchan and Kacchan.
  • In and Yoh (Japanese for Yin and Yang) from Cos Prayers.
  • Marchiano's 12 Sisters in Coyote Ragtime Show. All twelve of them are named after the months of the year (though their relative ages [they're gynoids] are not the same as the order of the months). The three "youngest" sisters are October (Octo), November (Nove), and December (Dece).
  • Yua and Mia Kusunoki from Chaos;Head.
  • Sailor Moon: Deimos and Phobos (Rei's pet crows) are both named for Mars' two moons. Phi and Chi (and Theta) are named for Greek letters. Lethe and Mnemosyne are named around the idea of memory.
  • Luki and Noki from Dogs: Bullets & Carnage.
  • Fist of the North Star:
    • Raiga and Fuga who are modeled after Raijin and Fujin (the Twin Gods of Thunder and Wind in Japanese mythology).
    • The true identity of the Heavenly Empress is none other than Lin's twin sister Lui.
    • Raoh's suspiciously similar elder brother Kaioh, although they're not exactly twins.
  • Nijuku and Sanju from Shoulder-a-Coffin Kuro, whose names are also contracted versions of the Japanese words for twenty-nine and thirty.
  • Zero and Ichiru Kiryu from Vampire Knight. 'Zero' literally means 'zero' and the 'ichi' in 'Ichiru' means 'one'.
  • Zero and Rei from Kurohime.
  • Hana (flower) and Ageha (butterfly) in Papillion.
  • Yanbo and Mabo from 20th Century Boys, though these seem to be nicknames.
  • Creepy Twins Hansel and Gretel from Black Lagoon.
  • Slayers has main character Lina and her (never-appearing) older sister Luna.
  • The Kongo Twins of Eyeshield 21 are named Agon and Unsui, which is all part of a very intricate pun:
    • Kongo-Rikishi are the two guardian statues seen at the entrance of Japanese Buddhist temples. The nicknames for these statues are "Agyo" and "Ungyo".
    • Symbolically, "a" represents birth/beginning since it's the first character of the Sanskrit alphabet and "Un" represents death/ending since it's the last character. Thus referring to something as an "A-Un relationship" is another way of saying it's harmonious and natural.
    • An "a" statue refers to a statue with an open mouth. An "un" statue is one with a closed mouth (usually frowning). Guess which twin is the quiet one and which one's the talker?
  • There is a yaoi manga called Twins Labyrinth (not about Twincest) where the twins are named Rin and Ren.
  • Tekkaman Blade has a main character and Evil Twin named Takaya and Shinya. Teknoman breaks the pun by renaming Shinya as Cain.
  • Mei and Kyu in Yu-Gi-Oh!; "meikyu" means labyrinth. In the dub their names become Para and Dox.
  • This sometimes happens in Magical Girl anime where the main character as two sidekicks/assistants/what have you. Examples include Posi and Neganote  from Creamy Mami and Pigu and Mogu from Fancy Lala (renamed Pog and Mog in the English dub, despite never being seen on TV).
  • Mipple and Mepple from the original Pretty Cure.
  • While not twins exactly, Ran, Miki, and Suu from Shugo Chara! were named after the members of a Japanese singing group from the 1970s called Candies.
  • Shizuki and Yuzuki from Hekikai No Aion. Shizuki's name means "calm moon" and Yuzuki is "kind moon".
  • An episode of Pokémon features Forrest and Forrester. Their original names are Jiro ("second son") and Ichiro ("first son") respectively.
  • Risa and Riku from D.N.Angel.
  • Takuma and Kazuma from Gakuen Babysitters share the same character for "horse," which also goes along with the rest of the characters' Animal Theme Naming.
  • Code Geass has Princes Castor and Pollux Rui Britannia in one of the video games. There's also Oldrin Zevon and Orpheus Zevon in the manga spinoff OZ The Reflection.
  • Fraternal twins Miki ("tree trunk") and Kozue ("tree top") Kaoru from Revolutionary Girl Utena, and reflecting their names Miki is the quieter, more stable one while Kozue is a flashy Attention Whore, especially towards her brother, but is a lot less emotionally stable.

     Comic Books  
  • A Spanish Comic serie features Zipi and Zape, named after the word zipizape, meaning chaos. Their father wanted to call them Romulus and Remus, but their mother disagreed because they would get to many IncrediblyLamePuns.
  • In Marvel Comics, the Fenris twins Andreas and Andrea von Strucker; and mutants Jeanne-Marie and Jean-Paul Beaubier. Additionally, the latter twins' code names, Aurora and Northstar, are both astronomy-themed.
  • Twin sisters Dusk and Dawn of Noble Causes.
  • The Flash:
    • Dawn and Don Allen, the twin children of the second Flash. One suspects their parents resorted to nicknames early on, since the two are homophones in most American dialects.
    • Albert Desmond and his "psychic" Evil Twin Alvin both went by Al.
  • Michael and Michelle Carter from Booster Gold, were given the masculine and feminine versions of the same name respectively.
  • Amusingly enough, Thompson and Thomson (originally Dupond and Dupont) from the Tintin comics are not twins. They're not even related, despite being identical except for the shapes of their mustaches. Dupond with a D has the slightly d-shaped one, and Dupont with a T has the slightly t-shaped one.
  • Tambi and Bambi Baker from Strangers in Paradise. (Real names: Mary Beth and Sara Beth.)
  • In Paperinik New Adventures, when you have a character who's an artificial intelligence named ONE, you can't REALLY act surprised when his twin, TWO, shows up. Or when he goes evil for that matter.
  • Pre-Crisis on Infinite Earths, two of Clark Kent's neighbors in his apartment building were twin sisters April and May Marigold.
  • While not phonetically similar, the Teenage Mutant Ninja Turtles share themed names, as Splinter named them after Renaissance artists; Michelangelo, Donatello, Leonardo and Raphael.
  • Donald Duck:
    • A trio of brothers Huey, Dewey, and Louie.
    • There's Daisy's nieces April, May, and June. They only appear in the comics.



  • Parodied in the third Austin Powers with the twins Fook Mi and Foo Kyu.
  • Noreen and Doreen from Hairspray.
  • President Scroob's twin mistresses, Marlene and Charline, from Spaceballs.
  • Star Wars: Luke and Leia Skywalker, Ann and Tann Gella, Jaina and Jacen Solo.
  • Dawn and John from the second Care Bears movie.
  • Mia and Tia, the Miata twins from Cars.
    • Also Rusty and Dusty RustEze and Johnny and Jamie.
  • Flora and Fauna, the Conjoined Twins from The Addams Family.
  • Speaking of Conjoined Twins, Terri and Terry from Monsters University.
  • In the sequel to the deliberately campy The Lost Skeleton of Cadavra, two characters who had been killed off turn out to have had identical twins. One of them merely shares the last two letters of his dead brother's name, but the other one has exactly the same name. When he's asked whether it ever caused confusion, he explains "We have different last names".
  • In Face/Off, the fraternal twin terrorists Castor and Pollux Troy (Castor and Pollux are the Gemini twins).
  • Adelita and Scardelita from The Book Of Life.


  • In the Anne of Green Gables series, there are three sets of twins:
    • Davy and Dora Keith
    • Gerald and Geraldine Raymond
    • Nan and Diana Blythe (named after Anne Shirley and her childhood best friend, Diana Barry)
  • Tweedledee and Tweedledum of Alice in Wonderland. In The Care Bears Adventure in Wonderland, the Wizard calls them simply "Dim" and "Dumb". This suggests that Tweedle might be a surname, much like Turanga or Mao. But these Tweedles still have their own theme: low intelligence.
  • The Baby-Sitters Club:
    • Marilyn and Carolyn.
    • And later, when Abby joined the club, her twin was named Anna. Which is rather funny, considering the Author admitted that Abby and Anna were called Lucy and Ethel in drafts, as naming the twins was the grand prize of a fan contest.
    • There are also twins named Mariah and Miranda in the girls' class at school.
    • Terri and Tammy Barkan, Ricky and Rose Salem. Averted with the Pike triplets Adam, Byron, and Jordan.
  • Most twins featured in A Song of Ice and Fire have half-rhyming or alliterative names, including the Tyrell guards Erryk and Arryk (named after a famous historical pair of twins in-universe), Aegon and Aemon Blackfyre (although those are both popular names in their family tree), Horas and Hobber Redwyne, and Jeyne and Jennelyn Fowler. Averted with major characters Cersei and Jaime, though.
  • Alanna, herself a twin, from Tamora Pierce's Daughter of the Lioness, named her twins Alan and Alianne. Alan was the name of her late father, as well as the name she used while posing as a boy during her knight training. However, in an aversion, her twin's name was Thom. Which itself means twin.
  • Rhyme and Reason from The Phantom Tollbooth, on top of the fact that most characters in the story are just about the definition of Anthropomorphic Personification.
  • Sara and Tara Leighton from Tales Of MU.
  • Adele and Eleda from The Truth Tellers Tale. The mirror-image names are a reference to them being Polar Opposite Twins, but the author also gave everyone else in their family palindromic names.
  • Tira and Kira from the Belgariad and prequels, and even more so once they get their wizard names: Beltira and Belkira.
  • From Discworld "Pyramids", a pair of twins named Ptaclusp IIa and Ptaclusp IIb (their father being simply Ptaclusp). They're actually pronounced "two-ay" and "two-bee".
  • Happens in J. R. R. Tolkien's Middle-Earth (The Silmarillion, The Lord of the Rings, etc), although here it is only part of the larger tradition of family members commonly being given similar names: Amrod and Amras (Fëanor's twin sons, who were also both named Ambarussa); Haleth and Haldar, the twin children of the human chieftain Haldad; Dior's twin sons Eluréd and Elurín; twins Elrond and Elros; Elladan und Elrohir (Elrond's twin sons); Folcred and Fastred (twin sons of a king of Rohan).
  • Also happens in Narnia, specifically Archenland, which may be connected given C.S. Lewis' and Tolkien's friendship and their influence on each other. Archenland is known for sets of twins with similar names such as Cole and Colin, Corin and Cor, and Dar and Darrin. In The Horse and His Boy, Cor tells Aravis this is an established naming tradition.
  • In the Cambridge Latin Course, there are a pair of twins named Loquax and Anti-Loquax. This sort of thing may have been relatively common practice among the ancient Romans; see Real Life below.
  • Anatole, a French mouse who is also a cheese expert, has three sets of twins (sextuplets?): Paul & Paulette, Claude & Claudette, and Georges & Georgette.
  • David Weber does this in the Honor Harrington series with the Masadan ships in Honor of the Queen.
    • Power and Dominion
    • Throne and Principality
    • Angel and Archangel
    • David and Solomon
    • Cherubim and Seraphim
      • Most of these are from the medieval celestial hierarchy; in decreasing order, Seraphim, Cherubim, Thrones, Dominions, (Virtues,) Powers, Principalities, Archangels, and mere Angels.
  • Shakespeare's The Comedy of Errors features two sets of twins who both have the same name. This is somewhat justified in that both pairs were raised separately.
  • From Harry Potter: Padma & Parvati Patil and Lorcan & Lysander Scamander Luna's twin sons with Rolf Scamander, grandson of the author of Fantastic Beasts & Where to Find Them. Averted with the most notable pair of twins in the series, Fred and George Weasley.
    • Played straight in the Norwegian version where the Weasley-twins are renamed Fred and Frank.
  • Daisy and Demi in Little Women, named after their parents Margaret (Meg) and John.
  • Sent up in Ray Romano's book Everything And A Kite:
    Now with twins, I don't know what it is, but parents have a natural instinct to give them those soundalike, same-initial, cutesy names.
    "Hey, meet our twins, Timmy and Tommy."
    Once again, it's cute when they're four, but by ten they're in therapy.
    Each twin needs to have his own personality and that should start with the name. It should be unique in and of itself, and not dependent on the sibling. That's the healthiest thing you can do for them as parents.
    I can see different personalities already starting to develop in my boys.
    Gregory's the independent one, outgoing and daring and not afraid to try anything.
    Schmegory... well, he's got a few problems.note 
  • In BattleTech, a renegade group of Clan Jade Falcon scientists created children that were genetic clones of their war hero, Aidan Pryde. All named children in the book had anagrams of Aidan for their names.
  • East of Eden, which draws heavily on the Cain and Abel story from The Bible, first depicts the relationship with two brothers (not twins) named Charles and Adam. When Adam's twin sons are born, he considers actually naming them Cain and Abel, but a neighbor tells him that would be asking for trouble. He goes with Caleb (Cal) and Aaron (Aron) instead. Of course, the relationship repeats anyway.
  • V. C. Andrews has done this a few times: Carrie and Cory Dollanganger, Deirdre and Darren Marquet, Cade and Adrian Eaton, Justin and Austin in the "Secrets" series. Averted with Celeste and Noble, Richard and Melanie, Cary and Laura, Ruby and Gisselle, and both sets of Pierre and Jean Dumas.
  • Over the last two books in the Teenage Worrier series, Letty's classmate gets pregnant with twins and is forced to drop out of school. She names them Barin and Rabina, which Letty finds funny, but turns out to be significant because the names are more or less anagrams of "Brian" - Brian Bolt is the father.
  • Bradley and Brian in the Calendar Mysteries series.
  • Triplets Snipp, Snapp, and Snurr in the Swedish picture book series by Maj Lindman, who also wrote a series for girls with triplets Flicka, Ricka, and Dicka.
  • The Malazan Book of the Fallen series gives us the triplets Envy, Spite and Malice. With the added info that if there was another one she'd be called Venom.
    • Compared to that, the twins Stavi and Storii have very tame theme naming.
  • Robert A. Heinlein seems to have been unable to give twin characters non-thematic names: Castor and Pollux from The Rolling Stones, Laz and Lor (Lapis Lazuli Long and Lorelei Lee Long) from Time Enough for Love. At first it seems that Tom and Pat Bartlett, from Time For The Stars, are an exception — but they were named for their father's two favorite figures from American history and their mother's two favorite Renaissance artists, and thus are actually Thomas Paine Leonardo da Vinci Bartlett and Patrick Henry Michelangelo Bartlett.
  • Chalet School - the Maynards' triplets: Mary Helen, Mary Margaret and Mary Constance (although they go by "Len", "Margot" and "Con" respectively.)
  • Geek Love has Conjoined Twins Iphigenia and Electra (nicknamed Iphy and Elly).
  • Subverted in The Power of Five in Jamie and Scott's case; their first names came from the box in which they were found and their last from the doctor who checked them out.
  • Achille and Hercule Poirot are both named after Greek heroes with the final "s" removed. Except Achille Poirot doesn't exist.
  • Heidi and Hannah in Hope Was Here.
  • Flora and Ferdy Devere in Agent Angel.

    Live Action TV 
  • Arrested Development has identical twins named "George Oscar" and, presumably, "Oscar George". note 
  • In Denji Sentai Megaranger, the not so twin Shibolena (絞れな) and Hizumina (歪な) share a name that are synonym with the word "twist". It's more like theme naming since the entire Nejirejia were named after the word "twist" too.
  • Northern Exposure: Joel Fleischman's twin brother Jules show up for one episode. Although it was strongly implied that Jules isn't real.
  • Seventh Heaven has the Camden babies Sam and Dave. Yes, that's a theme, Sam and Dave are the musical duo that sang "Soul Man".
  • Although they're not actually twins, the Identical Stranger nurse who replaced Laverne Roberts in Scrubs is called Shirley. As in Laverne and Shirley.
  • Miss Piggy's nephews Andy and Randy Pig in Muppets Tonight.
  • Porter and Preston on Desperate Housewives. Their siblings are Parker and Penny.
  • Beverly Hills 90210 twins: Brandon and Brenda.
  • Power Rangers RPM has Half-Identical Twins Gem and Gemma. Likely justified as being codenames given to them by the government think tank they were abducted into - their friend in the tank was known as "Dr. K" and specifically could not remember her real name.
  • No twins in Wonderfalls, but an example close to the Ben 10 quote above: The members of the Tyler family are named Karen, Darrin, Sharon, Aaron... and Jaye.
  • In an episode of Wings, Lowell is asked to name his pregnant cousin's child, and she has twins, which gives him some trouble, since what with Lowell being what he is, he thinks the names have to rhyme. Not long after, Joe jokingly throws out Nancy and Fancy, which Lowell immediately loves, leading to the line: "If in 25 years a very large man named Fancy Mather shows up to kill you, this is why."
  • From Newhart: "I'm Larry, this is my brother Darryl, and this is my other brother Darryl."
  • Privileged takes the "thematically similar" route with Rose and Sage.
  • Popular featured the Tuna twins, April and May.
  • In the second series of ITV crime drama Whitechapel, Ronnie Kray's twin sons who are not actually related to him, although they don't know this, Jimmy and Johnny Kray.
  • The Amazing Race had the teams of Derek & Drew (Season 3) and Kami & Karli (Season 5).
  • Utterly averted on The West Wing: Andy's twins are named by two different people, for completely different reasons, and in fact not even at the same time.
  • Towards the end of Dark Angel, it was revealed that the heroine Max had a long-lost twin sister named Sam.
  • The Doctor Who serial The Twin Dilemma featured twins called Romulus and Remus. Unfortunately the actors playing them had difficulty pronouncing the letter "R".
  • In an episode of Full House Jessie and Becky attend a support group for parents of twins. One set of parents there named their two kids, Phil and Phyll. The father is also named Phil and the mother is named Phyllis.

  • In Vocaloid, twins Rin and Len respectably mean "right" and "left". Also, their last name Kagamine includes the character for "mirror", representing their mirror representations of each other.

  • Romulus and Remus: Founders of Rome.
  • Apollo and Artemis: Fraternal twin offspring of Zeus.
  • Castor and Pollux: The original Gemini. Averted with those.
  • Amphion and Zethus: Sons of Zeus. First and last letter of the alphabet could count...if not for the fact that zeta is not the last letter of the Hellenic alphabet (that's omega).

     Video Games  
  • Gauche and Droite from Tales of Vesperia. They even wield swords in their respective hands.
  • Mio and Mayu from Fatal Frame II: Crimson Butterfly. The story also includes twins named Sae and Yae, Azami and Akane, and Itsuki and Mutsuki. (The entire game is essentially about a village that considers twins to be one spirit.)
  • The Neptunia series has Rom and Ram.
  • Palom and Porom in Final Fantasy IV.
  • Hurdy and Gurdy in Final Fantasy XII.
  • Ai and Yu from Final Fantasy: Unlimited. In addition to being homophones for I and You, Ai can mean "love, affection, friendly" and "indigo" while Yu can mean "happy, pleased" or "jade".
  • Lucas and Claus in Mother 3. They were actually named after the protagonists of Agota Kristof's novel The Notebook. Lucas and Claus are anagrams of each other. Not that you can tell when they're written in katakana...
  • Lei-Lei and Ling-Ling, twin Chinese girls who use a Dangerous Forbidden Technique to fuse into a Chinese Vampire in Darkstalkers.
  • Solid and Liquid Snake (of Metal Gear) are twins named after opposing states of matter, while the third brother is named Solidus. This has led to jokes (and more than a few Urban Legends Of Zelda) that there may be a fourth Gas Snake out there somewhere (and knowing Kojima this may very well be possible). note 
  • Twins Chinami and Ayame of Gyakuten Saiban 3 have flower-themed names. Their names in the English Phoenix Wright: Ace Attorney: Trials and Tribulations are Dahlia and Iris.
  • Ariel and Mariel in Summon Night: Swordcraft Story not only have similar names, but dress the same (though in different colors). At one point Mariel refers to Ariel as "big sister", but as they are specifically called twins, this is probably a title of respect.
  • Kat and Ana of WarioWare. Yes, they're ninjas. But are they better?
  • Dante and Vergil from Devil May Cry, named after the two protagonists of the Divine Comedy.
  • Hannah and Hinnah from The Last Remnant.
  • Vent & Aile of Mega Man ZX. French for "Wind" & "Wing", respectively.
    • Though they aren't twins so much as alternate universe equivalents of each other (or something).
    • And of course Rock & Roll from the original. They're not quite twins, as Roll was built a bit later, but it still fits.
    • There's also Crea and Prea (create and pray) from Mega Man Zero, named by Alouette.
    • And Mega Man Battle Network has the Hikari twins, Netto (熱斗) and Saito (彩斗). Both names share a kanji character and are both puns on computer terms - "netto" (ネット) is short for "intaanetto" (インターネット), Japanese for "Internet", and "saito" (サイト) means "web site". In the English version, their names were changed to Lan and Hub, both computer terms.
  • Ingram & Viletta (a corruption of Baretta) from Super Robot Wars, both named after guns. They're not ''exactly'' twins, though.
  • Billy and Jimmy Lee from the Double Dragon series. The NES version of the third game infamously misspelled the former's name as "Bimmy" in the 2-Player version of the opening intro.
    • Their counterparts in River City Ransom are named Randy and Andy, the Dragon Twins. In the Japanese Kunio-kun games, their names are Ryūichi ("first dragon") and Ryūji ("second dragon") Hattori.
  • Vocaloid has Rin and Len Kagamine. Their names are a pun on the words "right" and "left", respectively.
  • The Edison twins Jed and Ned in Day Of The Tentacle.
    • The whole Edison family gets in on this. In total, there are Dr. Fred, Weird Ed, Edna, Dead Cousin Ted, Red, Ned, Jed, Zed, Zedna and Ved (The latter three being in the far future, explaining their use of Xtreme Kool Letterz.)
  • Serena and Sera (Suu and Muu in the Japanese version) from Rune Factory 2.
  • Bubble Bobble games: Bub(blun/by) and Bob(blun/by), the main protagonists in the games. And Coro(ron/n) and Kulu(lun/n), that female Beta Couple in Bubble Symphony.
    • In Bubble Bobble Plus (WiiWare), Pab and Peb, a different female Beta Couple. (refer to Title Operations Guide in Wii Shop Channel)
  • Maori's twin sisters Koito and Kouta in Arcana Heart. It's more obvious in Japanese, their names both start with the kanji for 'small'.
  • Gouken (Strong Fist) and Gouki (Strong Demon) from the Street Fighter series, although this is Lost in Translation due to the latter becoming "Akuma" in the international versions.
    • Also, Yun and Yang
  • While the cast of Eternal Sonata falls under something more like Population Theme Naming (so that March and Salsa aren't particularly noteworthy), a better example, similar to Kat and Ana above, can be found in Tenuto's fields early in the game: a pair of twin girls named Sop and Rano.
  • Big Bang Beat's Kendo and Kyudo Nakanishi are named for their respective fighting styles - Kendo is the "way of the sword" (practiced with the 'shinai' that Kendo uses as well as actual swords), and Kyudo is "the way of the bow", or archery.
  • See Chaos;Head in the "Anime" folder above. (Warning: it's a Spoiler.)
  • Eirika and Ephraim of Fire Emblem: The Sacred Stones.
  • Redmond and Blutarch in the backstory for Team Fortress 2 just so happens to be the founders of the rivalling companies Reliable Excavation Demolition and Builder's League United, aka RED and BLU. You will also notice that the first three letters of the brothers' names syncronize pretty well with the acronyms for their companies.
    • And now their long lost third-triplet brother, Gray, who grows up to command a machine army.
  • Single-Minded Twins Timmy and Tommy from Animal Crossing series.
    • Also, the triplets, Mable, Sable and Label Able.
  • Many members of the Twins trainer class in the Pokémon series use this trope, especially in the Gen II games. Twins Ann & Anne are probably the most extreme example. They also tend to use identical, similar, or complementary Pokémon.
  • Ami and Mami Futami from The Idolmaster franchise.
  • Though not twins, Gears of War gave us brothers Anthony, Benjamine and Clayton Carmine. A rather dark Running Gag involves one Carmine dying in each game - though after voting it was averted with Clay.

    Visual Novels 
  • Mion and Shion from Higurashi no Naku Koro ni. The "on" in both names is the same kanji, 音 (meaning "sound").
  • Miho and Maho Shirayuki of Tokimeki Memorial 2. Maho's name is especially ironic, in that she's the "shadow sister" of the two, while the Kanji "Ma" (真) of her name means "Truth" in Japanese.
  • The Meido twins from Tsukihime, Hisui (jade) and Kohaku (amber), are named after their respective eye colors.

  • Thoss and Thlassa in Juathuur.
  • Sally and Sammy in LnM. Their nicknames for each other, L and M, come from being the only letters in their names that are different.
  • Magical 12th Graders: Despite not actually being twins, Yeorum and her older sister Gyeowul fit this trope quite neatly. "Gyeowul" means winter and "Yeorum" means summer, so it's often assumed they were born in winter and summer respectively. The truth is that they were both born in December, albeit a year apart. Yeorum was just named to fit Gyeowul's theme.
  • The Same-Sex Triplets born to Robin and Leslie in Shortpacked! are named Abby, Tabby and Gabby, but these are just nicknames and their full names are Abigail, Tabitha and Gabriella respectively.

  • Subverted in We're Alive. Latch and Scratch are nicknames.
  • In Red vs. Blue, there are a pair of twin Freelancers codenamed North Dakota and South Dakota.
  • Toki and Doki and Brownieand Brittani. The former is a play on Japanese word for "sometimes" (tokidoki) and in the case of the latter, well, we don't really know where that came from, though that could be used to to denote their personalities as well as physical differences (Brownie is a blonde and Brittani is a brunette).

     Western Animation  
  • Azula's elderly Creepy Twin teachers Lo and Li from Avatar: The Last Airbender, playing off a Chinese phrase that means "to mumble endlessly".
  • In The Legend of Korra, sequel to The Last Airbender above, Korra's fraternal twin cousins, Desna and Eska, are named after rivers : the Desna is a river in Russia and Ukraine that flows into the Dnieper, and the Eska is a river in southern Alaska.
  • Sherri and Terri from The Simpsons. Patty and Selma are an odd exception to the theme naming rule. Kang and Kodos are also an interesting topic, considering they both look alike, but whether they are even related is still up for debate.
  • Kim Possible:
    • Kim's younger brothers, the twins Jim and Tim Possible.
    • Shego's twin brothers are Wego. Both of them.
    • Their father James "Jim" Possible has a non-twin brother, Slim. Plus, mention was made of an ancestor named Mim (short for Miriam). The Possible family got a lot of mileage out of that rhyme scheme.

  • Tomax and Xamot, the twin leaders of COBRA's Crimson Guard, in G.I. Joe.

As in "Ben Tennyson. Gwen also shares his last name. Kevin's last name, however is Levin... as in "Kevin Eleven". note 
  • Camp Lazlo provides an interesting subversion. Of the loon twins, the most commonly referred-to one is "Ping" which makes you think the other's name would be "Pong". In actuality, though, the first is named "Ping Pong" and the other is named "Dave". It is, however, played straight with Chip and Skip, the dung beetle twins.
  • DuckTales: Huey, Dewey, and Louie, the nephews of Donald Duck and Uncle Scrooge McDuck. They rhyme without sharing any letter combinations.
  • The Proud Family had fraternal twin babies BeBe and CeCe, which not only rhyme, but are a reference to Gospel music artists BeBe and CeCe Winans, a brother and sister duet group.

  • Molly and Polly from Pigeon Street ("Molly and Polly, they're two of a kind / They look both the same when they're seen from behind / But when they turn round then it's easy to see / Who's Molly with an M and Polly with a P").
  • Single-Minded Twins Hip and Hop Koopa in The Adventures of Super Mario Bros. 3.

     Real Life  
  • http://www.behindthename.com/twins.php is a page on such theme naming.
  • Kishimoto Masashi, author of Naruto, has a twin brother Kishimoto Seishi, author of 666Satan. The last character in both names is the same.
  • The Social Security list of popular names for twins shows that this is distinctly a case of Truth in Television. Nearly all of them rhyme, alliterate, fit into a theme, or are names of famous siblings. This could be a case of statistics not telling the whole truth. It makes sense that two similar names would be used on more sets of twins than two unrelated names. And the numbers aren't that big; less than two percent of the sets of twins born per year have name sets on that list.
  • Mark Antony and Cleopatra's twins, Alexander Helios and Cleopatra Selene. Helios is the god of the sun; Selene is the goddess of the moon.
  • The famous newspaper advice columnists Abigail Van Buren and Ann Landers were identical twins. Their real names are/were Pauline Esther (the original Abby — the current columnist is her daughter) and Esther Pauline (the late Ann).
  • New Zealand had a case where the parents wanted to name their twins Fish and Chips. This was blocked by the courts. The courts did allow a request from another set of parents to call their twins Benson and Hedges. More details can be seen here

  • Jennifer Lopez and Marc Anthony named their twin children Max and Emme. As in Dragon Tales.
  • It was apparently somewhat common for Romans to name one kid Xxxx and the other Anti-Xxxx. In other words, one kid was defined as being the other one's opposite. The Romans were very uncreative about naming in general and had a tendency to give their daughters the same name, so this probably wouldn't have stood out.
  • Rami Malek (known for his role in The Pacific and Night at the Museum, just in case if you don't recognize him) has a twin brother named Sami Malek.
  • Actress Jill Hennessey has a twin sister named Jacqueline. In other words, "Jack" and "Jill".
  • Ronnie and Reggie Kray, notorious London gangsters.
  • Back in the Middle Ages, "Adam and Eve" were common as twin names. Fridge Logic makes you wonder why parents were naming siblings after a married couple, however, until you realize that Eve was a clone created from cells taken from Adam's side, and therefore both were genetic identical twins. (Not that anyone in the Middle Ages would have thought of that.)
  • Legendary Mixed Martial Arts fighters and identical twins Antônio Rodrigo Nogueira and Antônio Rogério Nogueira, with only their middle names being slightly different. To avoid confusion, most fans refer to them as "Big Nog" and "Lil Nog" (given that Rogério cuts weight to fight at light heavyweight and his "big brother" doesn't), or less commonly, "Diet Nog" (Rogério has even been seen wearing a Diet Nog t-shirt). They've even been referred as this by the announcers on TV (more for Lil Nog, Rodrigo can also be differentiated by his nickname Minotauro).
  • Funny enough it's subverted in Danish culture. The strange thing about this is that many, if not most, normal siblings have similar sounding names but in case of twins, parents are apparently obeying the advices of child psychology.
  • Kin Narita and Gin Kanie, the oldest twins ever (lived to be 107 and 108 respectively) - Kin means "gold" and Gin means "silver".
  • Averted with Bill and Tom Kaulitz — though, amusingly enough, the name Tom means, simply, "Twin".
  • Totally played straight in China, where not only twins are subjects of the trope, but entire families. Chinese names are usually two-part names, with two elements. In twins and often in non-twinned siblings, the same element is often used for either the first or second part of the given name, and then different elements used for the other. Well known examples include Madam Chiang Kai-shek, whose birth name was Soong May-Ling. Her sisters were Soong Ai-Ling and Soong Ching-Ling.
  • LaShawn Maurkice Pouncey and James Michael Pouncey (centers from the Pittsburgh Steelers and Miami Dolphins, respectively) seem like an aversion, until you realize both use their middle lames, Maurkice and Mike.
  • Swedish songwriter (among other things) Emil Norlander named his twin sons Tore and Nore. Besides going through life as part of a rhyme, Nore Norlander was also stuck with an Alliterative Name yet didn't get to be a superhero.
  • Mariah Carey has twins and named the girl Monroe (after Marilyn), and the boy Moroccan (after...the style of furniture).
  • Yoruba (Nigerian) culture has specific names for twins: Taiwo and Kehinde (literally, "first" and "second" born of twins respectively, regardless of gender). Many used them as middle names because every 5th person you met probably shared your name!
  • All five Dionne Quintuplets were named for the Virgin Mary: Marie Reine Alma, Yvonne Édouilda Marie, Annette Lillianne Marie, Cécile Marie Émilda, and Émilie Marie Jeanne.
