Scooter: It's pathetic.
She does stunts and
I assist her
Skeeter: He's my brother!
Scooter: And they tell me she's my sister!

A Sub-Trope of the Odd Couple wherein the odd couple are twins, usually identical brothers or sisters. A prominent exception is actually in the former Trope Namer, The Patty Duke Show. It featured identical cousins, who were described as "One pair of matching bookends, different as night and day" in the Expository Theme Tune.

Basically, Sibling Yin-Yang for (usually identical) twins. They'll usually embrace using Identical Twin ID Tags to help the differentiation.

Sometimes overlaps with Cain and Abel, in which case you might expect Fearful Symmetry. Also frequently overlaps with Foolish Sibling, Responsible Sibling and Red Oni, Blue Oni.

Compare Evil Twin. Extreme opposite is Single-Minded Twins or Creepy Twins.

    Anime and Manga 
  • Digimon Frontier: Kouji and Koichi. Kouji is arrogant and kind of a jerk at first, working by himself because he thinks the others will only drag him down. As time goes on, he shows a much kinder side. His Digimon forms are wolf-based and his element is light. Meanwhile, his twin is similar in appearance but far more soft-spoken and willing to be in the group once he's de-brainwashed. And, his Digimon forms are lion-based and his element is darkness (Dark Is Not Evil).
  • D.N.Angel: Riku and Risa even come out and say that their personalities are completely different. Risa is very girly and rather shallow (most of the time), while Riku is tomboy-ish and more down to earth.
  • Durarara!!: Mairu and Kururi Orihara actually invoked this. They actually flipped a coin to decide which girl got which trait. Strangely enough, their roles (Mairu as the Genki Girl and Kururi as The Quiet One) switch when they're on the internet. Even weirder is the fact that they don't consider themselves separate people.
  • Eyeshield 21: The Kongo twins Unsui and Agon. Unsui has a shaved head like a monk (it's sort of a theme at their school) is intensely hard-working, diligent, cautious, a very good athlete and basically a decent guy. But Agon (with a distinctive dreadlock hairstyle) is the series' Jerkass, a Jerk Jock to the extreme (including the womanizing, which apparently started in middle school) who gets away with being a sociopathic thug, slacker and general all-around asshole because he is a talent seen only once in a hundred years. It emphasized by the fact that 'A' and 'Un' represent "beginning and end" aka birth and death.
  • Fushigi Yuugi gives us easygoing, kind, polite Amiboshi contrasted to Hot-Blooded Jerkass Suboshi. Heck, even their weapons are different: Amiboshi has a flute which he can use for Mind Control on his opponents (for good or evil purposes), and Suboshi prefers to just smash through everything with a Killer Yo Yo. Even their clothes reflect just how opposite they are: Amiboshi wears a blue tunic, and Suboshi wears an orange one. (At least in the series; in promo artwork, they are very frequently dressed exactly alike.)
  • Toddlers Takuma and Kazuma from Gakuen Babysitters. The former is perpetually cheerful, while the latter always looks like he's about to cry.
  • Although the latter being conceived in a less-than-natural fashion, Amata Sora and Kagura Demuri from Aquarion Evol fit this to a T. Kagura is a hotblooded warrior from the enemy land raised to be a savage killing machine, while Amata is an insecure, shy and gentle guy with issues regarding his mother's apparent abandonment when he was a kid. Them being opposites of each other is actually a plot point.
  • Glass Fleet's Vetti and Cleo exemplify this trope. Though, their personalities are passed off as them having been raised separately, with the younger one subjected to mental and sexual abuse, giving him his screwed-up personality.
  • Hekikai No Aion: The twin sisters Shizuki and Yuzuki. Shizuki is a Manipulative Bitch and an Ill Girl, on the other hand, Yuzuki is a Ditz and a Dumb Muscle.
  • High School Star Musical has two pairs - Nayuki's younger sisters, Tsumugi and Yuki, are more typical and aren't major characters. But separated twins Tsubasa and Itsuki - who aren't even known to be related - have a large part of their conflict revolve around how they've developed into this since being separated.
  • I'm Gonna Be an Angel!: Noelle (the light) and Silky (the darkness) as described by Mikael. Mikael and Raphael might also count.
  • The Fubuki brothers in Inazuma Eleven. Shirou is a gentle, calm and timid defender, while Atsuya is a Hot-Blooded and rude forward. Coincidentally, Shirou's hair is bluish-gray and Atsuya' s hair is pink.
  • Is Kichijoji the Only Place to Live? has Miyako and Tomiko. Miyako is loud, cheerful and extroverted while Tomiko is a quiet introvert who prefers books to partying. They do share some things in common though such as their love of heavy metal music.
  • Kiss x Sis: We have Emotional Red Oni Ako and Soft-Spoken Blue Oni Riko.
  • Lucky Star: Kagami and Tsukasa. The former is a somber Tsundere while the other is a ditzy Cloudcuckoolander. When asked about this by Konata, they point out that they are fraternal twins.
  • Fuka and Fumika Narutaki of Mahou Sensei Negima!. The former's the trouble-making class prankster while the latter's constantly worried about how the former's pranks will get them in trouble as she gets dragged along.
  • In Miracle Girls, Tomomi is an outgoing and athletic tomboy while Mikage is feminine, studious, intellectual, and bad at sports.
  • Gundam SEED has Kira and Cagalli. The former is quiet, polite, and kind to a fault. The latter is brash, flippant, and has quite a temper. Also one's a boy and one's a girl. And one is genetically engineered to be physically "perfect", while the other...has superior physical abilities without any genetic alteration.
  • Monster: Anna and Johan Liebert. Anna's a nice, sweet girl who practices aikido and delivers pizza as a part-time job. Johan is the title character.
  • Yuma and Yuna Kashiwagi from Pani Poni Dash!. Yuma is an extreme extrovert, Yuna is an extreme introvert. Yuma goes so far as to actively sabotage Yuna's attempts at being more accepted just to keep eyes on her.
  • Pandora Hearts has Alice and the Will of the Abyss. Alice is boisterous, tomboyish, ill-mannered and she likes to wear dark dresses as opposed to her sister, who is lady-like in every way and always wears light-colored dresses. Their opposite personalities, tastes, and clothing are what makes obvious which twin was in control of Alice's body in the flashbacks.
  • Pokemon Omega Ruby Crimson Passion & Pokemon Alpha Sapphire Indigo Wisdom has twins Alpha and Omega. Omega is a calm boy with blue Tsurime Eyes while his older brother Alpha is a hot-headed goofball with red Tareme Eyes.
  • Ranma ½: Towards the end of the manga, there is Pink and Link, identical twin girls from a village of herbalists that neighbours Shampoo's village of "Chinese Amazons" and who practice different branches of an unnamed "Martial Arts Herbalism", a fighting style that revolves around plants and herbalistic concoctions. Pink, who is usually smiling, is a wicked and vicious girl who loves to poison people. Link, who is usually frowning, is a kind and gentle girl who considers it her duty to heal those her sister hurts. Despite these opposite natures, they care for each other deeply and are capable of uniting with singular purpose when given motive... which means that, in their actual appearance in Nerima, they function more like Single-Minded Twins.
  • Suiseiseki and Souseiseki from Rozen Maiden are very much this, both including a Tomboy and Girly Girl relationship, but with several more differing characteristic traits. Where Souseiseki is stoic, Suiseiseki is emotional. Souseiseki is serious and collected, while Suiseiseki is mischievous. Souseiseki believes it is the duty for every doll to participate in the Alice Game regardless of personal attachments, while Suiseiseki strictly opposes the Alice Game due to fear of losing her sisters.
  • Spirited Away: The identical twin sisters Yubaba and Zeniba. Yubaba is selfish and materialistic; Zeniba, while vengeful at first, turns out to be kindly and humble.
    • It's worth noting, though, that the sisters aren't really polar opposites—Yubaba has an introspective side (musing about the nature of humanity and its greed), treats her workers relatively well, so long as they work hard, and genuinely loves her son Boh to the point of spoiling him. Similarly, Zeniba can be just as nasty as her sister—one of her first lines to Chihiro is a threat to rip the girl's tongue out if she says anything about her presence. Miyazaki seems to be deconstructing this trope with the characters, pointing out that unlike fairy tale villains, most adults are both bad and good, with positive and negative qualities alike (a fact suggested by Chihiro eventually calling both sisters "Granny").
  • Private Actress has the twins Shuuto and Yuuto, Shiho's clients in one chapter. Older twin Shuuto is a Mr. Fanservice and a famous model, while younger twin Yuuto is just as good looking but a very awkward Shrinking Violet. Shuuto, then, hires Shiho to pose as Yuuto's suitor, in an attempt to help him. Massively subverted: Shiho eventually finds out that Shuuto and Yuuto are the same person and a case of Split Personality.
  • Saint Seiya has the twin brothers Saga (thoughtful, wise, just until his Superpowered Evil Side kicks in) and Kanon (selfish, scheming, arrogant until he has a Heel–Face Turn.) For major irony, Saga is the Gemini Saint, with Kanon inheriting his position once Saga dies.
    • From the villainous side, the twins gods Hypnos and Thanatos. Sure, they are Creepy Twins on their own, and aside from acting similarly, they also have similar creepy eyes. However, most of the times, they are more of this trope because of their personality, as they are textbook examples of Red Oni, Blue Oni with Thanatos as the red oni and Hypnos as the blue oni. Thanatos have much shorter fuse than Hypnos ever had, does show more emotion that Hypnos ever does, will jump into the fight if challenged, and underestimated humans in general. Hypnos however, hates fighting, and will seek ways to avoid fighting and calmly analyzes his enemies. This is even more prominent in Saint Seiya: The Lost Canvas, where they still share similar personality with their classical counterpart, where when they are defeated and sealed, Thanatos continue cursed Pope Sage pettily and furiously when Hypnos accepted his loss calmly and congratulates Hakurei instead.
  • Saint Seiya: The Lost Canvas continues this tradition with arrogant, narcissist, megalomaniac, self-centered, scheming, sleek and dainty Aspros, with the gritty and self-sacrificial Defteros. And yes, they are the Gemini Saints of their era, where Defteros had to kill Aspros because he showed his true colors, wanting to kill Defteros so that he could be the Pope. After Aspros'death, Defteros takes the Gemini Cloth with him and becomes the new Gemini Saint
  • In Saint Seiya Omega we have Gemini Paradox who has a crazy split-personality and good, loving, kind Gemini Integra. Same thing happens. Paradox is beaten by Ryuuho, and Integra picks up the Gemini Cloth afterwards during the Pallas War.
  • Samurai High School: Sakakido Kou and his sister Sakakido Tsukiko are Masculine Girl, Feminine Boy.
  • Rumiko Takahashi's one-shot The Samurai has identical twin ninja sisters, one of whom is a total nymphomaniac, while the other Does Not Like Men and Hates Being Touched. Woe be unto the person who confuses the latter for the former.
  • The Tamagotchi anime features Miraitchi and Clulutchi. Miraitchi is more outgoing, though panics easily. Clulutchi is more serious and thoughtful but isn't as sociable.
  • There, Beyond the Beyond: gives us twin boys both named Virid Visette Viridian, who are summed up quite nicely by their titles: "The Mad Prince" and "The Sane Prince".
  • To Love-Ru features Momo and Nana Deviluke, which also personify this trope very well. Momo is a Yandere Chessmaster sex maniac and can talk with plants. Nana is a B-Type Tsundere Ingenue prude and can talk with animals.
  • Trigun: Vash and Knives. One is a genocidal maniac and the other is a pacifist. Vash is also all about how other people feel and love and peace, and Knives doesn't even do empathy for his twin with whom he has an effing psychic link. Vash acts like a fool whenever he can and Knives is all superiority and icy control except when his temper gets away from him. They do have a bit in common still when you get past the good and evil divide. For instance, scary if you get them mad. Stubborn as hell. Charisma. Way of speaking, when serious, is even a little similar. Pretty good, when you consider they've been separated over a hundred times as long as they were together. When they were kids in the anime, one was unusually mature and one was goofy. No prizes for which. In the manga, they were much more similar, but Vash was more outgoing and Knives was more sensitive.
  • Hamel and Sizer from Violinist of Hameln. Hamel is loud, obnoxious and tends to spaz out while his sister Sizer is calm, sensible and serious. He's arrogant and loves to boast while she's a bit shy and doesn't like a lot of attention. Them being opposites is also emphasized by the fact Hamel is half-demon while Sizer is half angel, and she starts as a villain while Hamel is the hero.
  • In Wasteful Days of High School Girls, Hisui is a Shrinking Violet Nightmare Fetishist, while her twin sister Kohaku is an extroverted romantic.
  • Yu-Gi-Oh!:
    • Rua and Ruka (Leo and Luna, respectively, in the dub) from Yu-Gi-Oh! 5D's. Rua is a rowdy, cocky duelist who overestimates himself. Ruka is quiet, introverted and is usually the one to notify Rua when he goes too far.
    • The original series' Yugi and Yami Yugi can be counted as this if you consider them twins (of the split personality/alternate guy living in your head kind), with a dash of Sibling Yin-Yang.
    • The Tenma twins from the spin-off from the original series, Yu-Gi-Oh! R. Gekkou is mature, gentle, reasonable and already independent from Pegasus, meanwhile Yakou is very dependent on Pegasus, that he flips his shit upon Pegasus's disappearance and takes over Kaiba Corporation to resurrect Pegasus, effectively becoming the Big Bad, spends his time on screen showing his insanity, gloating off his victory and telling the protagonists he is unstoppable, or ranting about the fact that Gekkou used to be Always Someone Better to him. In their flashback too, they are this. Gekkou is cheerful and always in the spotlight, meanwhile Yakou is gloomy and forgotten or only seen as the inferior version of Gekkou. Their names reflect this too. Gekkou means "Moon Verse" when Yakou means "Night Verse". Lampshaded by Yakou himself in his match against Yugi.
  • Michele and Sara Crispino from Yuri!!! on Ice. Michele is short-tempered and uptight, while Sara is friendly and more down-to-earth.

    Comic Books 
  • Jezebel and Dinah in Blacksad: Dinah is a black bear (= dark brown) with a white patch on her chest, Jezebel a polar bear (= white) with a dark patch on her chest. Otherwise, they share face structure, and body and hair type. Personality-wise, Dinah is softer and Jezebel harder, although both have it in them to do what they need if it's for righteous revenge.
  • Ember and Suntop in ElfQuest. She is a feisty, red-headed partially wolf-blooded mortal Wolfrider who is destined to become the next Chief of the Wolfriders. He is the complacent, magical, blonde, immortal grandson of the mystic leader of the Sun Village and the apprentice of the equally mystic Mother of Memory. Word of God is that they actually chose these different destinies while in the womb.
  • The Flash:
    • Hyperactive, Fun Personified speedster Bart Allen (aka (Impulse) and his collected, scheming, evil clone Thaddeus Thawne (Inertia). Bart even mentions The Patty Duke Show the first time they meet, suggesting they switch places to befuddle their friends. Thad responds by punching Bart in the nose.
    • The Tornado Twins, Don and Dawn Allen, are barely shown enough to have characterization other than as Single-Minded Twins, but their individual personalities are All There in the Manual: Don is studious, levelheaded, and prefers to carefully think of a plan before taking action, while Dawn is extroverted, impulsive and will follow her gut nine times out of ten.
  • Gregory Stark and Tony Stark in Ultimate Avengers. Becomes a case of Cain and Abel.
  • In X-Men Noir, Thomas and Robert Halloway are, respectively, a know-it-all afflicted with Chronic Hero Syndrome and a crude, violent sadist. It's probably important to note that they were adopted by different families after their father died.
  • Young Avengers: Caring geek Wiccan and hyperactive bad boy Speed.
  • Swordquest: Earthworld has Gemini, who is composed of an evil white shade and a helpful black shadow.
  • In Silver Surfer: Dawn Greenwood's Establishing Character Moment is when she and her sister Eve see a shooting star (actually the Surfer), Eve wishes to go everywhere and see everything, and Dawn wishes that the star could keep going so everyone could get a wish. Eve thinks Dawn's wasted her wish since she didn't really ask for anything, and Dawn doesn't understand why anyone would want to leave their home town. As an adult Eve's been all over the world, and Dawn still doesn't see why anyone would leave. (Too bad The Call Knows Where She Lives.)
  • The Avengers Scarlet Witch and Quicksilver are polar opposites most of the time—Pietro is stern and stubborn and hot-tempered, his sister is gentle and patient and demure. This is especially true of their earliest appearances, where it was easier to define Wanda's personality as "Pietro's opposite". Over the years, however, Wanda has gained a stubborn temper of her own, making her more similar to her brother.
  • Kate Kane and her twin sister Beth were like this as children. Kate was aggressive, protective, and mostly stoic, while Beth was far more meek and openly emotional.
  • The Adami twins, Gabriel and Mags, in C.O.V.E.N. Gabriel has a healthy tan, blond hair, and wears bright blue and white preppy clothes. Mags has pale skin, dyed black hair, and is a black and red-wearing Goth. Gabriel acts like a smooth and friendly guy, but he's a complete Narcissist with a sadistic streak. Mags acts aloof and ruthless but has a Hidden Heart of Gold. Gabriel wants their father's approval despite the years of abuse. Mags saw getting discarded as a blessing, and only returned to protect her brother.
  • Wonder Woman and her twin sister Nubia are very different in personality and appearance. Diana is a Technical Pacifist raised in an all-female paradise with a Caucasian appearance and Nubia is a Combat Pragmatist raised in a hellish male-dominated culture with a Sub-Saharan appearance.
  • Played With in PS238—Tyler's "brother," Toby, is actually a clone who's now been adopted by his parents. The most obvious difference between them is that Tyler is a Muggle Born of Mages (and secret Badass Normal) while Toby is a Reality Warper, but this trope also fits their personalities: Tyler is dry and rational, while Toby is increasingly showing himself to be extroverted and cheerful (if possibly a Stepford Smiler).

    Fan Works 
  • In Boy Scouts ½, the Porter twins. Kirstin is a gentle, sweet homemaker. Nicole is a greedy, ruthless money seeker.
  • In Empath: The Luckiest Smurf, Hefty and Handy are the Brains and Brawn twins but are not identical.

  • In The Rabbit And The Puppy Kagami and Tsukasa from Lucky Star. Kagami is a Tsundere and Tsukasa is TheDitz.
  • Meg's Family Series has Chris and Jillian's twins, C.J. and Tilly. The former basically inheriting their parents' (lack of) brains, and the latter being a super-genius.
  • We are the Chatroom Gems has Yella and Azura Diamond, this story's versions of a human Yellow and Blue Diamond. Yella is cold, yells at a student (Lapis) for wearing a "Say hi if you're Bi" shirt, and is heavily implied to have undiagnosed IED, while Azura is emotional, has no problem with student's sexualities, and says that her depression is "apparently" obvious.
  • Used in the Brave fanvid BRAVE TWINS, which manipulates the film in order to split Merida's character into a pair of identical twins: one is a prim and proper princess while the other is a tomboyish Rebellious Princess. The plot revolves around the Tomboy Princess fighting to stop her sister from being married off because neither are ready to be married yet.
  • Downplayed in The New Adventures of Invader Zim: Steve and Viera aren't that different in personality, but their specialties are science and magic, respectively, and they initially clash about it a lot.
  • A Diplomatic Visit: Pinkie and her little twin sister Marble, as discussed in chapter 12 when she reveals she's a twin and Twilight reacts with surprise, since she's seen the Pie family portrait and Pinkie is the only pink one of her family. Pinkie replies that "Marble's a lot quieter and shyer and grayer than I am. Kind of like a mix of Mac and Fluttershy and a rock."
  • Leave For Mendeleiev features Chloe and Amber Bourgeois. While Chloe prefers using her father's connections and funds to coast along taking everything she feels obligated to have, Amber has been raised by their mother to work hard and earn things rather than relying upon the station she was born into. Naturally, Chloe believes that Amber has screwed her out of her mother's love by her very existence, rather than considering that it might have anything to do with how she's always cutting corners and trying to trick and bully her way into getting everything she wants handed to her.

    Film 
  • Eurotrip: The twins Jenny and Jamie are pretty different. Throughout the movie, the phrase "worst twins ever" is repeated.
  • Hellboy II: The Golden Army has Prince Nuada and Princess Nuala; while they are Half-Identical Twins in appearance, Word of God says they were intended to be as different as night and day in all other respects.
  • She's the Man: Sebastian and Viola. He's artsy and musical, and she's athletic and loves soccer. It's even lampshaded near the end of the movie.
  • The Reveal in Shock Treatment is the fact that this is the case of Brad Majors and Farley Flavors, who were separated as infants when their parents died.
  • Star Wars: Luke is a blonde, blue-eyed, calm, mild-mannered, naive, mystical, religious Jedi Knight. Leia is a brunette, brown-eyed, quick-tempered, sharp-tongued, worldly-wise, shrewd, practical politician. Interestingly, they parallel their parents' personalities from the Prequel Trilogy, with Luke taking after their mother Padmé while Leia takes after their father Anakin.
    • The Star Wars Legends show Luke having trouble teaching Leia to be a Jedi. What worked for him (he got a lot of Jedi qualities) won't work for her. Hot temper is not something a Jedi knight ought to have. Especially since she's pregnant with Han's baby while trying to learn.
  • The Parent Trap: In the 1998 remake, the twin girls, Annie James and Hallie Parker (Lindsay Lohan), are completely different. Annie is calm, reserved, and rather uptight while Hallie is relaxed, loud, outgoing, and a Big Eater. (Compare Annie with Cody and Hallie with Zack of The Suite Life.)
  • Susan and Sharon in the original The Parent Trap, to a lesser extent.
  • Markus and William Corvinus, from Underworld: Evolution, were twin brothers who respectively became the first vampire and first werewolf. One is scheming and pompous, the other is near-mindless and savage. Unusual in that we never learn if they'd been genetically identical or not, as William is already locked permanently in his wolf-man form at the time the film is set, but they probably were.
  • Rock star wannabe Roxy and Young Republican Jane in New York Minute.
  • Charlie and Donald Kaufman in Adaptation. have completely opposite approaches to screenwriting and to life.
  • In Double Trouble, David is an honest cop with slobby habits, and his brother Peter is an unrepentant cat burglar with a taste for culture.
  • The whole concept of Twins is that Arnold Schwarzenegger and Danny Devito play genetically-engineered twins, with Arnold being the product of attempting to make the perfect man and Devito being all the "genetic garbage" they were weeding out of Arnold.
  • In The Pretty One, Laurel and Audrey are identical twins. Audrey is self-assured, confident, and popular. Laurel is reclusive and is convinced that she is the inferior of the two.
  • Constantine has the aggressive cop Angela, and her twin sister Isabelle who is The Ophelia.
  • Quest for Camelot has the serious and snooty Devon and the boisterous, fun-loving Cornwall. Unfortunately, they're not only Polar-Opposite Twins, but they're also Conjoined Twins, and they're unable to use their shared body to fly or breathe fire until they learn to get along near the end of the movie.

    Literature 
  • Polgara and her twin Beldaran in The Belgariad series. The former is dark-haired, has a grim disposition, and grew up to be an immortal sorceress. The latter was blonde, had a sunny disposition, and married young to become the queen of an island kingdom and bear the royal line which would deliver the child of prophecy, before dying young of pneumonia. As Polgara's biography explains, the two were originally much more similar, but their mother tampered with them in the womb to prepare them for their destinies.
  • In Castle Hangnail, Molly is a Wicked Witch who likes bats and earwigs and animal skeletons and dresses in black as much as her parents will let her; Sarah loves pink and glitter and ponies, goes around making insipid comments to "Mr Bluebird" and "Miss Rabbit", and regularly visits the residents of the local retirement home.
  • Occurs in Gordon R. Dickson's Childe Cycle series of novels and short stories, in the characters of Ian and Kensie Graeme. Both are Dorsai (Proud Warrior Race Guys). Ian is the epitome of the Warrior - seemingly aloof and intimidating by his sheer presence. Kensie is his polar opposite - warm, caring, social - everything that Ian is not. In the stories, it's implied that together the two make up one individual. Ironically, it's Ian who's irresistible to women - without realizing it.
  • Double Trouble: Randi likes red, soccer, and is outgoing; Sandi likes pink and purple, schoolwork, and is rather quiet. They do agree that their two-year-old brother is a pill.
  • The Brothers Majere; easy going, heroic Boisterous Bruiser Caramon and intense, morally ambiguous Squishy Wizard Raistlin in Dragonlance.
  • Deliberately invoked in Raise the Titanic!. Pitt has been hunting for Silver and Gold, a pair of Soviet spies on the NUMA Titanic project. He's figured out Gold is Drummer and while much of his background was hidden, the FBI were able to discover he was one of a pair of non-identical fraternal twins. Sandecker says it must have been easy for one twin to lead to the other but Pitt corrects him that the two were very smart and played as total opposites in personality while rarely hanging out so no one would make any connection. Pitt himself was stumped until Drummer was going crazy about a submarine in trouble and Pitt realized his twin had to be one of the three men on board. Since one was eight years older than Drummer and the other Mexican, that left Merker.
  • Lampshaded in The Legendsong Saga. Glynn and Ember are twins who are both physical and personality opposites. Their only physical similarity is the same coloured eyes (yellow); personality contrasts include Ember�s musical talents and Glynn being tone-deaf.
  • In Dragon Bones, Erdrick is the shy, sensible twin, Beckram is a ladies' man and troublemaker. They look so alike that Beckram often persuades Erdrick to take his place at boring social occasions.
  • Shaun and Shem from Finnegans Wake probably count, but it's hard to figure out which is which, due to the book changing their names constantly. All you need to know is one is boring and dull, and the other is really creative and artistic.
    • Specifically, Shaun is dull and conformist but successful in society, while Shem is a slovenly outcast but also an artistic genius.
  • Owen and Porter from First Person Plural by Andrew Beierle. Owen is a book-reading drama nerd. Porter is a cheerleader-dating football player. Owen is gay, and Porter is straight. They are also conjoined twins sharing one body with two heads. This is incredibly awkward considering that Porter married a homophobic woman.
  • Nicky and Alex in the Full House book series grew up to be different, one tough, one shy, although in one episode of the show their father was concerned that their personalities would turn out the other way around.
  • The Eiran twins Eamonn and Grainne from Kushiel's Dart by Jacqueline Carey.
  • The Marlow twins Nicola and Lawrie from the Marlow series by Antonia Forest.They are so identical in looks that they are easily mistaken one for the other by people who don't know either of them well, but so different in mannerisms, behaviour, and speech, that anyone who does know them well can tell them apart immediately. Lawrie, a skilled actor, can more easily pass for Nicola when she wants to than Nicola can for Lawrie - a plot point in one of the books.
  • In the original Story Lottie and Lisa by Erich Kästner (aka "Das doppelte Lottchen"), the titular twins had extremely different personalities, which made their place change all the more hilarious, and later difficult. Lisa was a cheerful, bratty tomboy while Lottie was a sensible, serious, prim and proper girl who behaved almost like a grown-up. Most film versions omit this aspect.
  • Eve and Alexandra in Master of the Game are a Cain and Abel crossover version — Alexandra is sweet, honest, and innocent, with no ambitions towards running Kruger-Brent, Ltd. Eve is consumed by ambition and the desire to be the center of everyone's attention, and starting from the age of five she's determined to kill and/or ruin Alexandra, who's in the way. (Incidentally, author Sidney Sheldon co-created the much gentler Trope Namer years before.)
  • Abby and her twin sister Anna of The Baby-Sitters Club. Anna is musical, bookish, and introspective; Abby is athletic, noisy, and enjoys babysitting. About the only things they have in common are that they both have scoliosis and poor eyesight.
  • Dawn and Eve of Piers Anthony's Xanth are literally as different as day and night, from the fact that Dawn is red-haired and green-eyed, and is like the morning, while Eve is black haired and eyed and is like the night.
  • Belle and Samuel from Rolitania are very different, indeed. Belle is popular, sociable, and has thousands of Instagram followers. Samuel, on the other hand, is the Butt-Monkey of the class, a former NEET, and can hardly speak for himself when confronted.
  • Both the books and TV version of Sweet Valley High, with the Wakefield twins Jessica and Elizabeth.
  • The Tortall Universe gives us:
  • In Pierce's Circle of Magic universe, Nia the shy, retiring one (with woodworking magic) and Jory the hyperactive, overeager one (with cooking magic).
  • Tatterhood and her unnamed twin sister from the Norwegian fairytale are a perfect example of this: Tatterhood is an ugly but spirited princess who rides on a goat and singlehandedly beats up hordes of trolls and witches, while her sister is a beautiful, but helpless Damsel in Distress. Despite this, the twins are inseparable and get along famously.
  • Amoret and Belphoebe in The Faerie Queene: The former was adopted by Venus, the Goddess of Love and Beauty, and became a Proper Lady. The latter was adopted by Diana, the Goddess of Maidenhood and the Hunt, and became an Action Girl.
  • Robert L. Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde: Dr. Jekyll and Mr. Hyde may be considered a variation of this trope.
  • Emmeline and Adeline March from The Thirteenth Tale, who are totally passive and excessively violent respectively.
  • The twins in Flowers in the Attic Cory is quiet, polite and gentle. Carrie is loud, adamant and forceful.
  • Web Serial Novel Correspondence From The Goddess has Lydia Devin, the main character, a snarky aimless twentysomething who slowly gains divinity-level powers over the course of the story, and Elana Devin, her twin sister, who is perfect as perfect can be but doesn't seem to have any powers at all.

Tavia is quieter and less confident, but very skilled with electronics and computers, acting as an able Mission Control and support for her sister. Tavia makes herself sick with worry every time Bink goes on a job, is even more nervous when she has to go into the field herself and would like for them to go legit, but every time she tries Bink pulls them back into the life. Bink, for her part, considers Tavia naïve; her "legitimate" jobs have all involved someone taking advantage of her to accomplish something even shadier than thievery with her skills.

Patricia is the bold, Tomboyish, defiant and rude one; Piper is highly talented in piano, very sweet and polite, and much less inclined to make big moves out of fear of failure than her Determinator sister is.

  • In The Bible, we have Jacob and Esau. Esau is the older one, and he displays a Carpet of Virility and is a skilled hunter.

They were at odds with one another before they were even born—God explains to their mother that her difficult pregnancy came from them fighting in the womb. Though they manage to make peace... several years later.
    • According to Jewish tradition, Jacob's cousins/wives, Rachel and Leah, were also twins and had similarly disparate personalities, the former being a quiet introvert, the latter more gregarious and emotional.

    • Another example can be found in the 5th edition Tears of Isha campaign pack, which focuses on the war between Calaidan and Kaldor, twin scions of the High Elf house Coraith, one of whom defects to Naggaroth and becomes an evil Dark Elf while the other inherits the family estates and continues their proud High Elven traditions.

Also, Gennifer may be an unwitting lycanthrope.

  • Felix and Ted Huxley from Kindergarten 2. Felix is a pint-sized Rich Bastard who constantly belittles and bosses around his brother and is planning to have him murdered so he won't have to share his inheritance.

    Visual Novels 
  • Dahlia Hawthorne and Iris from Phoenix Wright: Ace Attorney - Trials and Tribulations. Dahlia is a ruthless sociopath who has been using her cute and innocent image to get away with murder, literally, for years and Iris is sweet, gentle, and compassionate, and honestly fell for the lead character while posing as her sister because she needed him for a master plan but didn't want to be bothered with actually seducing him.

  • Higurashi: When They Cry: Mion and Shion Sonozaki. Mion is assertive and bombastic, the leader of her True Companions; Shion is sly and seductive, preferring to manipulate people subtly rather than openly command them. It's even more odd when you realize that they're acting like each other, thanks to a Twin Switch they made when they were younger.
  • Tsukihime: Kohaku and Hisui. One is carefree, energetic and always smiling, while the other is silent with little expression. It's also odd when you consider that they switched places from when they were children: Hisui was originally carefree and cheerful, while Kohaku was shy and untalkative. Then they got older and things got worse for them (specially Kohaku), so Hisui buried her emotions to help Kohaku stay stable while Kohaku hid her very darkened True Self behind a facade of happiness.

Not entirely, though.
  • ef - a fairy tale of the two.: The Shindou sisters. Chihiro is an ingenue, Kei is a Shorttank.

They're a weird example though, in that Didi slowly budded off Gogo which would make her some kind of clone/daughter, but they see each other as twins and have a more sisterly relationship.
  • The Hong twins in Sharp Zero. Elliot is dorky, unorganized, and believes others see him as the evil twin and a screw-up. Marcus is the put-together Mom Friend was a straight-A student, and never gets in trouble.

  • Sikue and Tatsuma in Beyond Bloom, are not identical, but were "born" together. They are polar opposites in many ways, one being loud and aggressive, while the other is quiet and gentle. This is especially emphasized in their magic. Tatsuma has offensive abilities while Sikue's are defensive.
  • Played with in Ennui GO!. Izzy and her twin sister Adelie are very similar, the only real difference being that Adelie lacks Izzy's crippling depression and prefers alcohol to drugs.

Both dress somewhat alike but wear different colors: black or purple for Toki, reflecting her enigmatic, yet domineering but secretly kindhearted personality, and pink and white for Doki, reflecting her kind, gentle, and angelic personality. It isn't just that, according to Amoridere, Doki is more morally grounded than Toki is (as in, she wouldn't stoop to schemes or anything illegal to meet her demands, whereas the latter probably and more often than not would), along with being more levelheaded, and, Toki, well, she is described as being one who does what she wants, whenever she so wants to do it, consequences be damned.

Plus, the birthmarks on their face make them a literal example of Sibling Yin-Yang.

National Geographic has done an article on it.
