15->''"When me and my sister were little, we had two older twin sisters who would take care of us. We always called one The Angel and one The Devil, because one was really nice and the other was a complete bitch."''

17
18A SubTrope of the OddCouple wherein the odd couple are twins, usually identical brothers or sisters ([[Series/ThePattyDukeShow or cousins]], as long as they're still using the "identical appearance, contrasting personalities" motif).
19
20Basically, SiblingYinYang for twins, as there is an extra bit of irony when people born at the same time (and who usually [[AlwaysIdenticalTwins look the same]] as well) are so different. They'll usually embrace using {{Identical Twin ID Tag}}s to help the differentiation.
21
22Sometimes overlaps with CainAndAbel, in which case you might expect FearfulSymmetry. Also frequently overlaps with FoolishSiblingResponsibleSibling and RedOniBlueOni. Compare EvilTwin. The extreme opposite is SingleMindedTwins or CreepyTwins.

27[[foldercontrol]]
28
29[[folder:Anime & Manga]]
30%%* ''Manga/{{ARAGO}}'': Arago and Ewan fit this trope to a T.
31* Tsubasa and Arisa from ''Manga/{{Arisa}}''. [[TheAce Arisa]] is loved by everyone at her school, has good grades, and is the ClassRepresentative. [[{{Delinquent}} Tsubasa]] is nicknamed "the Demon Princess" and is constantly getting into fights and has lousy grades. [[spoiler:As it turns out, Arisa is very much a BrokenAce]].
32* In ''Manga/{{Aruosumente}}'', the twins [[RhymeThemeNaming Lante and Dante]]. Lante is cheerful, outgoing, chatty, frilly, and can't fight to save his life. Dante, on the other hand, barely talks at all, keeps to himself, cares only about Lante, and is the best fighter in the kingdom, to the point of being called a beast. Interestingly, it's Lante who may be a schemer and capable liar, while Dante is very straightforward.
33* ''Manga/BlackClover'': The House of Faust had twin sons, with Morgen being the picture of a good man, beloved by many and having joined the Magic Knights to save others while Nacht was a delinquent disapproved of by others who used his magic only for himself. Morgen's name even means "morning" in German while Nacht means "night" in German.
34* ''Manga/{{Bleach}}'': The sweet HouseWife-in-training[[note]]She's still a kid, after all.[[/note]] Yuzu and the rough {{Tomboy}} Karin.
35* ''Manga/BlueExorcist'' is essentially about a pair of these, as both Okumura brothers are very different: [[BigLittleBrother Yukio]] is a [[TheStoic stoic]] BadassBookworm TeenGenius, kind at heart but thoroughly steeped in moral grays, who subverts HalfHumanHybrid due to being sickly when young, while [[AntiAntiChrist Rin]] is a HotBlooded BookDumb AlmightyJanitor who is the inheritor of {{Satan}}'s power and holds himself to strict principles for fear his demonic heritage will drive him off the deep end. They fell into this when younger as well, with Yukio being a ShrinkingViolet CuteBookworm (and still has shades of both still), while [[BigBrotherInstinct Rin]] was a PintSizedPowerhouse {{loner|sAreFreaks}}.
36%%* In ''Manga/ChronoCrusade'' we have [[spoiler:Chrono and his EvilTwin Aion]].
37* ''Anime/DigimonFrontier'': Kouji and Koichi. Kouji is arrogant and kind of a jerk at first, [[IWorkAlone 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 [[spoiler:once he's de-brainwashed]]. And, his Digimon forms are lion-based and his element is darkness (DarkIsNotEvil).
38* ''Manga/DNAngel'': Riku and Risa even come out and say that their personalities are completely different. Risa is very girly and rather shallow ([[HiddenDepths most of the time]]), while Riku is tomboy-ish and more down-to-earth.
39* ''Manga/Eyeshield21'': 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 JerkJock 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 [[TheGift a talent seen only once in a hundred years.]] It's emphasized by the fact that 'A' and 'Un' represent "beginning and end" aka birth and death.
40* ''Manga/FushigiYuugi'' gives us easygoing, kind, polite Amiboshi contrasted to HotBlooded {{Jerkass}} Suboshi. Heck, even their weapons are different: Amiboshi has a flute which he can use for MindControl on his opponents (for good or evil purposes), and Suboshi prefers to just smash through everything with a KillerYoYo. 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.)
41* Toddlers Takuma and Kazuma Mamizuka from ''Manga/GakuenBabysitters''. Takuma is an outgoing PerpetualSmiler, while Kazuma is shy and very ProneToTears.
42* Although the latter being conceived in a [[LiteralSplitPersonality less]]-[[EnemyWithout than]]-[[EvilTwin natural]] fashion, [[spoiler:Amata Sora and Kagura Demuri]] from ''Anime/AquarionEvol'' fit this to a T. [[spoiler:Kagura]] is a [[FieryRedhead hotblooded]] [[BloodKnight warrior]] from the enemy land raised to be a savage [[AttackAttackAttack killing machine]], while [[spoiler:Amata]] is an [[ButtMonkey insecure]], [[FriendlessBackground shy]] and [[NiceGuy gentle guy]] with issues [[FreudianExcuse regarding his mother's apparent abandonment when he was a kid]]. [[CockFight Them being opposites of each other is actually a plot point.]]
43* ''Anime/GlassFleet'''s [[spoiler:Vetti and Cleo]] exemplify this trope. Though, their personalities are passed off as them having been raised separately, with the younger one subjected to [[spoiler:mental and sexual abuse]], giving him his screwed-up personality.
44* ''Manga/HekikaiNoAion'': The twin sisters Shizuki and Yuzuki. Shizuki is a {{Manipulative B|astard}}itch and a sick girl, on the other hand, Yuzuki is a [[TheDitz Ditz]] and a DumbMuscle.
45* ''Webcomic/HetaliaAxisPowers'': the BoisterousBruiser America and the ShrinkingViolet Canada are only implied to be twins, but they fit in fairly well. The show also has sweet, softhearted [[LovableCoward Italy]] Veneziano and his brother, the temperamental, hotheaded [[{{Tsundere}} Italy]] Romano.
46* ''Anime/HighSchoolStarMusical'' has two pairs - Nayuki's younger sisters, Tsumugi and Yuki, are more typical and aren't major characters. But separated twins [[spoiler: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.
47* Ukon and Sakon Futatsuki from ''Manga/{{i tell c}}'' are twins, and are as different as night and day. Ukon is cool and unflappable while Sakon is hyper-enthusiastic and prone to overreactions. Their [[HairContrastDuo hair colors]], [[LightDarknessJuxtaposition skin tone and uniform colours]] reflect their opposite personalities.
48* ''Anime/ImGonnaBeAnAngel'': Noelle (the light) and Silky (the darkness) [[spoiler:as described by Mikael. Mikael and Raphael might also count.]]
49* The Fubuki brothers in ''VideoGame/InazumaEleven''. Shirou is a gentle, calm, and timid defender, while Atsuya is a HotBlooded and [[{{Jerkass}} rude]] forward. Coincidentally, [[RedOniBlueOni Shirou's hair is bluish-gray and Atsuya's hair is pink]].
50* ''Manga/IsKichijojiTheOnlyPlaceToLive'' 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.
51* ''Kiss x Sis'': We have Emotional Red Oni Ako and Soft-Spoken Blue Oni Riko.
52* ''Manga/LuckyStar'': Kagami and Tsukasa Hiiragi; the former is a smart, no-nonsense {{Tsundere}} while the latter is sweet but also [[TheDitz ditzy]] and BookDumb. When asked about this by Konata, they point out that they are fraternal twins.
53* In ''Manga/MiracleGirls'', Toni is an outgoing and athletic tomboy while Mika is feminine, studious, intellectual, and bad at sports.
54* ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'' has [[spoiler: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. [[spoiler:And one is genetically engineered to be physically "perfect", while the other...has superior physical abilities without any genetic alteration.]]
55* ''Manga/Mars1996'': Rei was always [[RedOniBlueOni very active and prone to getting himself into trouble while Sei was quiet, artistic, and something of a crybaby]]. [[spoiler:And then the real reason it turned out they were opposites was that while Rei had it in him to be well-adjusted, Sei was actually a sociopath who placed no value in human life aside from him and Rei]].
56* ''Manga/{{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 [[ExactlyWhatItSaysOnTheTin title character]].
57* Fuka and Fumika Narutaki of ''Manga/NegimaMagisterNegiMagi''. The former is 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.
58* Yuma and Yuna Kashiwagi from ''Anime/PaniPoniDash''. 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.
59* ''Manga/PandoraHearts'' 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. [[spoiler:Their opposite personalities, tastes, and clothing are what makes obvious which twin was in control of Alice's body in the flashbacks.]]
60* ''Pokemon Omega Ruby Crimson Passion & Pokemon Alpha Sapphire Indigo Wisdom'' has twins Alpha and Omega. Omega is a hot-headed goofball with blue TaremeEyes, while his younger brother Alpha is a calm boy with red TsurimeEyes.
61* ''Manga/PrivateActress'' has the twins Shuuto and Yuuto, Shiho's clients in one chapter. Older twin Shuuto is a MrFanservice and a famous model, while younger twin Yuuto is just as good looking but a ''very'' awkward ShrinkingViolet. Shuuto then hires Shiho to pose as Yuuto's suitor, in an attempt to help him. [[spoiler:Massively subverted: Shiho eventually finds out that Shuuto and Yuuto are ''the same person'' and a case of ''SplitPersonality''.]]
62* ''Manga/RanmaOneHalf'': Towards the end of the manga, the story introduces 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 [[MartialArtsAndCrafts "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 SingleMindedTwins.
63* Miki and Kozue Kaoru from ''Anime/RevolutionaryGirlUtena''. Miki is polite, a model student, and a highly-skilled piano player, while Kozue is blunt, has a tendency to sleep around, and isn't very good at playing the piano.
64* Suiseiseki and Souseiseki from ''Manga/RozenMaiden'' are very much this, both including a TomboyAndGirlyGirl relationship, but with several more differing characteristic traits. Where Souseiseki is {{stoic}}, Suiseiseki is [[TheMcCoy emotional]]. Souseiseki is serious and collected, while Suiseiseki is [[ThePrankster 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.
65* ''Manga/SaintSeiya'' has the twin brothers Saga (thoughtful, wise, just [[spoiler:until his SuperpoweredEvilSide kicks in]]) and Kanon (selfish, scheming, arrogant [[spoiler:until he has a HeelFaceTurn.]]) For major irony, Saga is the ''Gemini'' Saint, [[spoiler:with Kanon inheriting his position once Saga dies]].
66** From the villainous side, the twin gods Hypnos and Thanatos. Sure, they are CreepyTwins on their own, and aside from acting similarly, they also have similar creepy eyes. However, most of the time, they are more of this trope because of their personality, as they are textbook examples of RedOniBlueOni with Thanatos as the red oni and Hypnos as the blue oni. Thanatos has a much shorter fuse than Hypnos ever had, does show more emotion than 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 ''Manga/SaintSeiyaTheLostCanvas'', 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 [[GracefulLoser accepted his loss calmly and congratulates Hakurei instead. ]]
67* ''Manga/SaintSeiyaTheLostCanvas'' continues this tradition with [[ItsAllAboutMe arrogant, narcissist, megalomaniac, self-centered]], scheming, sleek and dainty Aspros, with the gritty and [[LoveMartyr self-sacrificial]] Defteros. And yes, they are the Gemini Saints of their era, [[spoiler: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]]
68* In ''Anime/SaintSeiyaOmega'' we have Gemini Paradox who has a crazy split-personality and good, loving, kind Gemini Integra. [[spoiler:Same thing happens. Paradox is beaten by Ryuuho, and Integra picks up the Gemini Cloth afterwards during the Pallas War.]]
69* ''Manga/SamuraiHighSchool'': Sakakido Kou and his sister Sakakido Tsukiko are MasculineGirlFeminineBoy.
70* Creator/RumikoTakahashi's one-shot ''The Samurai'' has identical twin ninja sisters, one of whom is [[LovableSexManiac a total nymphomaniac]], while the other DoesNotLikeMen and HatesBeingTouched. Woe be unto the person who confuses the latter for the former.
71* The ''Anime/{{Tamagotchi}}'' anime features Miraitchi and Clulutchi. Miraitchi is more outgoing, though panics easily. Clulutchi is more serious and thoughtful but isn't as sociable.
72* ''Manga/ThereBeyondTheBeyond'': gives us twin boys both named Virid Visette Viridian, who are summed up quite nicely by their titles: [[AxeCrazy "The Mad Prince"]] and [[ManipulativeBastard "The Sane Prince"]].
73* ''Manga/ToLoveRu'' 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}} [[TheIngenue Ingenue]] prude and can talk with animals.
74* ''Manga/{{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 [[UsedToBeASweetKid Knives was more sensitive]].
75* Hamel and Sizer from ''Manga/ViolinistOfHameln''. 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.
76* In ''Manga/WastefulDaysOfHighSchoolGirls'', Hisui is a ShrinkingViolet NightmareFetishist, while her twin sister Kohaku is an extroverted romantic.
77* ''Franchise/YuGiOh'':
78** Rua and Ruka (Leo and Luna, respectively, in the dub) from ''Anime/YuGiOh5Ds''. 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.
79** 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 SiblingYinYang.
80** The Tenma twins from the spin-off from the original series, [[Manga/YuGiOhR 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 BigBad, spends his time on screen showing his insanity, [[UnsportsmanlikeGloating gloating off his victory]] and telling the protagonists he is unstoppable or ranting about the fact that Gekkou used to be AlwaysSomeoneBetter 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. [[ThemeTwinNaming Their names reflect this too.]] Gekkou means "Moon Verse" when Yakou means "Night Verse". Lampshaded by Yakou himself in his match against Yugi.
81* Michele and Sara Crispino from ''Anime/YuriOnIce''. Michele is short-tempered and uptight, while Sara is friendly and more down-to-earth.
82* In ''Manga/{{Zipman}},'' Kaname is an athletic NiceGuy who gets no respect thanks to his fiendish looks. Meanwhile, his brother Koshiro is a ChildProdigy turned TeenGenius with a gentle face that everyone admires, but is incredibly rude to his twin brother in private. Even their color schemes are opposite: Kaname is known for having wild white hair that gets him labeled "White Demon", Kaname's hair is normal and black. The English blurb even refers to them as this word-for-word.
83[[/folder]]
84
85[[folder:Comic Books]]
86* Jezebel and Dinah in ''ComicBook/{{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.
87* Ember and Suntop in ''ComicBook/ElfQuest''. She is a [[FieryRedhead feisty, red-headed]] partially wolf-blooded mortal Wolfrider who is destined to become the next Chief of the Wolfriders. He is the complacent, magical, blond, immortal grandson of the mystic leader of the Sun Village and the apprentice of the equally mystic Mother of Memory. WordOfGod is that they actually chose these different destinies while in the womb.
88* ''ComicBook/TheFlash'':
89** [[AttentionDeficitOohShiny Hyperactive]], FunPersonified 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 [[TwinSwitch switch places to befuddle their friends]]. Thad responds by [[KickTheDog punching Bart in the nose]].
90** The Tornado Twins, Don and Dawn Allen, are barely shown enough to have characterization other than as SingleMindedTwins, but their individual personalities are AllThereInTheManual: 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.
91* Gregory Stark and Tony Stark in [[ComicBook/UltimateMarvel Ultimate Avengers]]. [[spoiler:Becomes a case of CainAndAbel.]]
92* In ''ComicBook/XMenNoir'', [[spoiler:Thomas and Robert Halloway]] are, respectively, a know-it-all afflicted with ChronicHeroSyndrome and a crude, violent sadist. It's probably important to note that they were adopted by different families after their father died.
93* ''ComicBook/YoungAvengers'': Caring geek Wiccan and hyperactive bad boy Speed.
94* ''[[ComicBook/{{Swordquest}} Swordquest: Earthworld]]'' has Gemini, who is composed of an evil white shade and a helpful black shadow.
95* In ''ComicBook/SilverSurfer'': Dawn Greenwood's EstablishingCharacterMoment 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 hometown. As an adult Eve's been all over the world, and Dawn still doesn't see why anyone would leave. (Too bad [[TheCallKnowsWhereYouLive The Call Knows Where She Lives]].)
96* ''ComicBook/TheAvengers'': 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.
97* [[ComicBook/{{Batwoman}} 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.
98* 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 HiddenHeartOfGold. Gabriel wants their father's approval despite the years of abuse. Mags saw getting discarded as a blessing, and only returned [[BigBrotherInstinct to protect her brother]].
99* ''ComicBook/WonderWoman1942'': Franchise/WonderWoman and her twin sister ComicBook/{{Nubia}} are very different in personality ''and'' appearance. Diana is a TechnicalPacifist raised in an all-female paradise with a Caucasian appearance and Nubia is a CombatPragmatist raised in a hellish male-dominated culture with a Sub-Saharan appearance.
100* PlayedWith in ''ComicBook/{{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 MuggleBornOfMages (and secret BadassNormal) while Toby is a RealityWarper, 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 StepfordSmiler).
101* Bibbo Bibbowski is a tough, good-hearted bruiser in ''Comicbook/{{Superman}}'' comics. ''Comicbook/ThePowerOfShazam'' introduced Professor Bibbowski, equally good-hearted, but a scientist and NonActionGuy.
102[[/folder]]
103
104[[folder:Comic Strips]]
105* In the ''ComicStrip/{{Scamp}}'' ([[SpinOffspring Son of]] WesternAnimation/LadyAndTheTramp) comics (Specifically the newspaper continuity), Scamp and his siblings are two sets of these. Twin Sisters Fluffy and Ruffy are dignified and tomboyish, respectively, while non-identical brothers Scamp and Scooter are adventurous and timid, respectively.
106[[/folder]]
107
108[[folder:Fan Works]]
109* In ''Fanfic/BoyScoutsOneHalf'', the Porter twins. Kirstin is a gentle, sweet homemaker. Nicole is a greedy, ruthless money seeker.
110* In ''Fanfic/EmpathTheLuckiestSmurf'', Hefty and Handy are the BrainsAndBrawn twins but are not identical.
111* ''Fanfic/MoonSoldier'' features ditzy and emotional Usagi and her twin brother, the calmer and more responsible Akira.
112* In ''Fanfic/TheRabbitAndThePuppy'' Kagami and Tsukasa from ''Manga/LuckyStar''. Kagami is a {{Tsundere}} and Tsukasa is TheDitz.
113* ''Fanfic/MegsFamilySeries'' 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.
114* ''[[http://archiveofourown.org/works/8491420/chapters/19459867 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.
115* Used in the ''Brave'' fanvid ''WebVideo/BraveTwins'', which manipulates the film in order to split Merida's character into [[DecompositeCharacter a pair of identical twins]]: one is a prim and proper princess while the other is a tomboyish RebelliousPrincess. The plot revolves around the TomboyPrincess fighting to stop her sister from being married off because neither are ready to be married yet.
116* {{Downplayed}} in ''Fanfic/TheNewAdventuresOfInvaderZim:'' Steve and Viera aren't that different in personality, but their specialties are [[MagicVersusScience science and magic]], respectively, and they initially clash about it a lot.
117* ''Fanfic/ADiplomaticVisit'': 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."
118* ''Fanfic/LeaveForMendeleiev'' features [[AlphaBitch Chloe]] and [[TheFashionista Amber]] Bourgeois. While Chloe prefers using her father's [[ScrewTheRulesIHaveConnections connections]] [[ScrewTheRulesIHaveMoney and funds]] to coast along taking everything she [[EntitledBastard 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 [[WellDoneDaughterGal 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.
119* A common {{Fanon}} in the ''VideoGame/Persona3'' fandom is that the male and female protagonist options are twins and that the chosen protagonist is the SoleSurvivor of the car crash that killed their parents. In stories where the two are portrayed as twins who both survived, it's common for the male protagonist to be portrayed as an example of the SugarAndIcePersonality type, who doesn't open up to the rest of SEES for quite some time, whereas the female protagonist is portrayed as a StepfordSmiler, who doesn't show off her own inner despair no matter how she feels except in the DarkestHour.
120* ''Fanfic/APairingOfSouls'' features Shen Jiu adopting Shen Yuan as his younger twin brother. If Shen Jiu is an unrepentant asshole who constantly plans for the worst and tries to hide his vulnerable soft center, Shen Yuan is openly nice and personable to the point of naivety but will display a steely spine when his buttons are pushed.
121* ''Fanfic/PokemonResetBloodlines'' has two pairs of HalfIdenticalTwins with this dynamic, overlapping with FoolishSiblingResponsibleSibling:
122** Elwood and Aideen, the twins who got the remaining starter Pokémon from Professor Oak on the same day as Ash and Gary. Elwood is the calmer, more mature and levelheaded of the two, while Aideen has a fiery and more outspoken personality that her older brother often needs to rein in.
123** The Lono twins in Alola, Frax and Velvet, invert it: Frax, the male twin, is a {{Keet}} who is a bit BookDumb and tends to jump headfirst into situations, [[WomenAreWiser while his sister Velvet is more responsible, does better at school and tends to think things through]]. This even extends to their Pokémon, as Frax is noted to have befriended most of his mons with ease and they just followed him, while Velvet had to catch hers through battles the traditional way.
124* ''Fanfic/AllMixedUp'' has Carlos and Carol, who are very different from each other in personality, purpose and appearance despite being siblings. Carlos is the sentient paper fortune teller that runs the Language Room, who is depressed, forgotten, and has his colors inverted to highlight how tainted he is. Carol, the sentient paper fortune teller that runs the Math Room, is much more eccentric, bright, cheery and helpful, with her displaying a wide array of colors and agents coming to her often whenever they get stumped on math problems.
125* ''[[https://www.fanfiction.net/s/3481778/1/The-Hero-Strikes-Back The Hero Strikes Back]]'' has [[Franchise/StarWars Luke and Leia]] as mentioned below in Live Action, and a particular quirk in their training, where Luke has a preference for meditation and communing with the Force, while Leia is more active and prefers practicing Lightsaber forms. When being punished for teasing each other, Anakin has Luke work on his forms while Leia is forced to practice her meditation.
126* Harry and Danny in ''Fanfic/LifesCurseDeathsGift'' share a temper and a ChronicHeroSyndrome, but being SeparatedAtBirth ensured they grew quite distinct from each other. Harry lashes out in anger against injustice and was eager to drop his abusive relatives to join the Wizarding World, Danny is more cautious about antagonizing other people even when they clearly are in the wrong and is upset to leave his loving parents and sister in order to study magic at Hogwarts. It causes a lot of friction between them.
127* In ''Fanfic/KaijuRevolution'', one Mothra larvae is brown with blue eyes and is friendly and curious, while the other is black with red eyes with a more solitary personality and more violent when provoked.

130[[folder:Films -- Animation]]
131* ''WesternAnimation/QuestForCamelot'' has the serious and snooty Devon and the boisterous, fun-loving Cornwall. Unfortunately, they're not only Polar-Opposite Twins, but they're also ConjoinedTwins, 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.
132* ''Anime/SpiritedAway'': 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 [[DeconstructedTrope 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").
133[[/folder]]
134
135[[folder:Films -- Live-Action]]
136%%* ''Film/{{Adaptation}}'': Charlie and Donald Kaufman have completely opposite approaches to screenwriting and to life.
137* ''Film/Constantine2005'' has the aggressive cop Angela, and her twin sister Isabelle who is TheOphelia.
138* ''Film/DeadRingers'' has identical twin gynecologists Elliot and Beverly Mantle. Elliot is smooth and a ladykiller while Beverly is a ShrinkingViolet. They are so identical that the only way Beverly can have sex is for Elliot to seduce the woman [[BedTrick then substitute Bev for himself at the very last moment in the bedroom]].
139* ''Film/DoubleTrouble'': David is an honest cop with slobby habits, and his brother Peter is an unrepentant cat burglar with a taste for culture.
140* ''Film/{{Eurotrip}}'': The twins Jenny and Jamie are pretty different. Throughout the movie, the phrase "worst twins ever" is repeated.
141* ''Film/GlassOnion'': One twin is a high-flying big-city Disruptor, the other is a humble small-town teacher. [[spoiler:The latter Brand twin, Helen, has to impersonate her glamorous executive sister Andi, and is very uncomfortable throughout.]]
142* ''Film/AHauntingAtSilverFalls'': The Dahl twins. When Jordan goes to meet with their father, Holly is described as having been a good Christian girl, while Heather acted out because she was afraid of being forgotten.
143* ''Film/HellboyIITheGoldenArmy'' has Prince Nuada and Princess Nuala; while they are HalfIdenticalTwins in appearance, WordOfGod says they were intended to be as different as night and day in all other respects.
144* In ''Film/LicenseToDrive'', protagonist Les (Creator/CoreyHaim) is laid back, fun-loving, and just a typical teenage boy in most respects. His twin sister Natalie is bookish, serious, and depicted as being rather a stick in the mud. The trope is lampshaded when Natalie aces her written driving exam and Les fails his. He manages to knock out the computer system before his grade can be recorded; this leads the woman running the exam to just allow him to go ahead with the practical exam. Her logic?
145-->''"How different can you really be from your ''twin sister''?"''
146* ''Film/NewYorkMinute'': Rock star wannabe Roxy and [[BlondeRepublicanSexKitten Young Republican]] Jane.
147* ''Film/TheParentTrap1961'': Susan and Sharon. Sharon is the ProperLady of the two, while Susan is a hip tomboy. In both the original and the remake, this is at least partly the result of their parents' SolomonDivorce, with the ladylike Sharon/Annie raised by their mother while the scrappier Susan/Hallie was raised by their father.
148* ''Film/TheParentTrap1998'': The twin girls, Annie James and Hallie Parker, are completely different. Annie is calm, reserved, and rather uptight while Hallie is relaxed, loud, outgoing, and a BigEater.
149* ''Film/ThePrettyOne'': 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.
150* ''Film/ShesTheMan'': 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.
151* ''Film/ShockTreatment'': TheReveal is the fact that this is the case of [[spoiler:Brad Majors and [[BigBad Farley Flavors]]]], who were separated as infants when their parents died.
152* ''Franchise/StarWars'':
153** Luke Skywalker is a blonde, blue-eyed, calm, mild-mannered, naïve, mystical, religious Jedi Knight. Leia Organa (née Skywalker) is a brunette, brown-eyed, quick-tempered, sharp-tongued, world-wise, shrewd, practical politician. Interestingly, [[GenerationXerox they parallel their parents' personalities from the Prequel Trilogy, with Luke taking after their mother Padmé while Leia takes after their father Anakin]].
154** The Franchise/StarWarsLegends show Luke having trouble teaching Leia to be a Jedi. What worked for him (he has a lot of Jedi qualities) won't work for her. Hot temper is not something a Jedi knight ought to have. It also doesn't help that she's pregnant while trying to learn, and is constantly busy with politics. In the reboot, Luke ended up training Leia to become a Jedi without much trouble as seen in ''Film/TheRiseOfSkywalker''.
155** Also in ''Legends'', Han and Leia's first children are the twins Jaina and Jacen, who like Luke and Leia also partially take after their opposite-gender parent. Jaina, like Han, is blunt, mechanically-inclined, and an excellent pilot, while Jacen, like Leia, is more thoughtful and focused on responsibility. It becomes [[CainAndAbel much more tragic]] when Jacen turns to the dark side, emulating their grandfather Darth Vader, while Jaina grows more patient, and in the end, Jaina has to kill Jacen.
156* ''Film/ThroughBlackSpruce'': Despite them being identical, Annie and Suzanne are opposites in many ways. Before going to search for her sister, Annie seemed happy living in their rural home town, which Suzanne hated, leaving it for Toronto. Annie wears more masculine clothes mostly, while Suzanne became a model. Suzanne had gotten in trouble with drugs and an abusive boyfriend; conversely Annie is a sober, very responsible person overall.
157* ''Film/Twins1988'': The premise of the movie is that Creator/ArnoldSchwarzenegger and Creator/DannyDeVito play genetically-engineered twins, with Julius Benedict (Schwarzenegger) being the product of attempting to make the perfect man and Vincent Benedict ([=DeVito=]) being all the "genetic garbage" they were weeding out of Julius.
158* ''Film/Underworld2003'': In ''Evolution'', Markus and William Corvinus are 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, [[AlwaysIdenticalTwins but they probably were]].
159[[/folder]]
160
161[[folder:Literature]]
162* ''Literature/ArtemisFowl'': Beckett is cheerful, ditzy, and much prefers physical activity, while Myles is basically a toddler version of [[ChildProdigy Artemis]].
163* ''Literature/BakaAndTestSummonTheBeasts'': the NiceGuy Hideyoshi and the {{Jerkass}} Yuuko. Further differences include that Hideyoshi is not smart enough to qualify past Class F (the bottom of the barrel), while Yuuko is in Class A (the best), and Hideyoshi is a beautiful singer but Yuuko is completely tone-deaf.
164* Polgara and her twin Beldaran in ''Literature/TheBelgariad'' 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.
165* ''Literature/BrimstoneAngels'': Main character Farideh is broody, angsty, and painfully self-aware that her heritage as a Tiefling (human-devil hybrid) marks her as an outcast. Her twin sister Havilar is cheerful, friendly, and if she has any awareness of how people view her and her sister, she never shows it (much to Farideh's chagrin). On top of that, Havilar is a traditional ActionGirl, who took to their adoptive father's martial training ''much'' better than Farideh, whose decision to become a warlock sets the plot in motion. Part of Farideh's angst is that she's convinced people want her to be ''more'' like Havilar.
166* In ''Literature/CastleHangnail'', 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.
167* Occurs in Creator/GordonRDickson's ''Literature/ChildeCycle'' series of novels and short stories, in the characters of Ian and Kensie Graeme. Both are Dorsai ({{Proud Warrior Race Guy}}s). 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 - ''[[ChickMagnet without realizing it]]''.
168* ''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.
169* The Brothers Majere; easy going, heroic BoisterousBruiser Caramon and intense, morally ambiguous SquishyWizard Raistlin in ''Literature/{{Dragonlance}}''.
170* Deliberately invoked in ''Literature/RaiseTheTitanic''. 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.
171* Lampshaded in ''Literature/TheLegendsongSaga''. 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.
172* In ''Literature/DragonBones'', 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.
173* Shaun and Shem from ''Literature/FinnegansWake'' 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.
174** Specifically, Shaun is dull and conformist but successful in society, while Shem is a slovenly outcast but also an artistic genius.
175* ''{{Literature/Durarara}}'': Mairu and Kururi Orihara actually [[InvokedTrope invoke]] and [[SubvertedTrope subvert]] this. They actually ''flipped a coin'' to decide which girl got which trait. Strangely enough, their roles (Mairu as the GenkiGirl and Kururi as TheQuietOne) switch when they're on the internet. Despite how differently they act, the subversion lies in the fact that they [[SingleMindedTwins don't actually consider themselves as separate people]].
176* 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.
177* Nicky and Alex Katsopolis, in the ''Series/FullHouse'' spinoff book series, grow up to be different; one is tough, one shy. Interestingly, in one episode of the show, their father was concerned that their personalities would turn out the other way around.
178* The Eiran twins Eamonn and Grainne from ''[[Literature/KushielsLegacy Kushiel's Dart]]'' by Jacqueline Carey.
179* The Marlow twins Nicola and Lawrie from [[Literature/TheMarlowSeries 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.
180* In the original Story ''Literature/LottieAndLisa'' by Erich Kästner (aka "Das doppelte Lottchen"), the titular twins had extremely different personalities, which made their [[spoiler: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.
181* Eve and Alexandra in ''Master of the Game'' are a CainAndAbel 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 Creator/SidneySheldon co-created the much gentler TropeNamer years before.)
182* Abby and her twin sister Anna of ''Literature/TheBabySittersClub''. 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.
183* Dawn and Eve of Creator/PiersAnthony's ''Literature/{{Xanth}}'' are literally as different as day and night, from the fact that Dawn is [[SignificantGreenEyedRedhead red-haired and green-eyed]] and is like the morning, while Eve is black-haired and eyed and is like the night.
184* Belle and Samuel from ''Literature/{{Rolitania}}'' are very different, indeed. Belle is popular, sociable, and has thousands of Instagram followers. Samuel, on the other hand, is the ButtMonkey of the class, a former NEET, and can hardly speak for himself when confronted.
185* Both the books and TV version of ''Literature/SweetValleyHigh'', with the Wakefield twins Jessica and Elizabeth.
186* The ''Literature/TortallUniverse'' gives us:
187** In ''Literature/SongOfTheLioness'', Alanna the down-to-earth ActionGirl who dislikes magic, academic pursuits, and social games, and Thom the fame-hungry career mage and scholar who thinks he's AboveGoodAndEvil.
188** A deliberate subversion of this trope in the next generation with Alanna's [[UntoUsASonAndDaughterAreBorn daughter and son]] Alianne and Alan in the ''Literature/TrickstersDuet'', who are neither this nor SingleMindedTwins. WordOfGod says this was to point out that there's not always some mystical weirdness about twins.
189* In Pierce's ''Literature/{{Circleverse}}'', Nia the shy, retiring one (with woodworking magic) and Jory the hyperactive, overeager one (with cooking magic).
190* Literature/{{Tatterhood}} and her [[NoNameGiven 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 DamselInDistress. Despite this, the twins are inseparable and get along famously.
191* Amoret and Belphoebe in ''Literature/TheFaerieQueene'': The former was adopted by Venus, the Goddess of Love and Beauty, and became a ProperLady. The latter was adopted by Diana, the Goddess of Maidenhood and the Hunt, and became an ActionGirl.
192* Robert L. Stevenson's ''Literature/TheStrangeCaseOfDrJekyllAndMrHyde'': Dr. Jekyll and Mr. Hyde may be considered a variation of this trope.
193* Emmeline and Adeline March from ''Literature/TheThirteenthTale'', who are totally passive and excessively violent respectively.
194* The twins in ''Literature/FlowersInTheAttic'': Cory is quiet, polite and gentle. Carrie is loud, adamant, and forceful. [[spoiler:Her personality shifts dramatically after Cory dies, however.]]
195* WebSerialNovel ''Literature/CorrespondenceFromTheGoddess'' 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.
196* Creator/JacquelineWilson's ''Double Act'' has [[TomboyAndGirlyGirl Tomboy Ruby and Girly Girl Garnet]]. This becomes more apparent when [[spoiler:Ruby cuts off her braids to distinguish herself further from her sister]].
197* Squirrelflight and Leafpool from ''Literature/WarriorCats'', especially when they're apprentices. Squirrelflight is sharp-tongued and energetic, and becomes a warrior, while Leafpool is calm and more reasonable, and becomes a medicine cat. They're even compared directly to fire and water once.
198* ''[[Literature/TheMillenniumTrilogy The Millenium Quadrology]]'' has Lisbeth and Camilla Salander. Lisbeth is a brilliant hacker with NoSocialSkills who stands up for abused women and children and has a strong moral code. Camilla is highly manipulative, does not care about those she considers "weak", and has very little in terms of morals [[spoiler:being the leader of a Russian crime syndicate]].
199* Cilla and Tina from ''Literature/IMissYouIMissYou''. Cilla is down to earth and is interested in directing theater while Tina is mainly interested in boys and can be quite petulant.
200* The Creator/JackieCollins novel ''Chances'' has Lucky and her brother Dario. Lucky has dark hair and a vigorous personality, and she's extremely ambitious. Dario is blonde and a slacker, more interested in his Porsche than the family business.
201* Tobi and Toklo from ''Literature/SeekerBears''. Tobi is timid, quiet, and delicate, while Toklo is adventurous and more than a little grumpy.
202* ''Literature/StarWarsScoundrels'': Bink and Tavia Kitik are amazingly identical physically, but couldn't be farther apart in personality. Bink is bold, outgoing, and a risk-taker, a ClassyCatBurglar who's very good at infiltration and the physical aspects of the robbery. Tavia is quieter and less confident, but very skilled with electronics and computers, acting as an able MissionControl 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.
203* ''Literature/IveBeenKillingSlimesFor300YearsAndMaxedOutMyLevel'' has the slime spirit twins, Shalsha and Falfa. The former is cold, bookish, and reserved, and the latter is warm, sporty, and outgoing.
204* ''Literature/FairyOak'': Vanilla and Lavender are this as well as being a NightAndDayDuo. Lavender was born at the stroke of midnight while Vanilla was born exactly twelve hours later. Vanilla is outgoing, friendly, and friendlier than her sister, who in turn is impatient, a bit aggressive, and NotAMorningPerson. The fact that they both have PersonalityPowers only drives the point home since Vanilla's magic is light-based and Lavender's is drawn from darkness.
205* ''Literature/HarryPotter'' has Parvati and Padma Patil. Parvati is the more outgoing twin, while Padma is the more studious twin. It's noted that the two are sorted into different houses, Parvati in Gryffindor and Padma in Ravenclaw, when family members are usually sorted into the same house.
206* ''Literature/AnansiBoys'': [[EmbarrassingNickname Fat Charlie]] and Spider start out as this. Fat Charlie is the mundane, responsible, and anxious twin with the dull accounting job and absolutely no knowledge of his family's supernatural background -- while Spider is an impossibly cool, impossibly confident party animal who goes through life without a care for anything or [[JerkAss anyone]] and is seemingly the only one of the two to inherit their father's TricksterGod powers. It's eventually even revealed that they are [[spoiler: not technically twin brothers, but rather Spider is Charlie's LiteralSplitPersonality, his magical half that was cast out of him by an old lady that he angered as a child. Although Charlie concludes that they have both grown into their own whole persons from it and the two still regard each other as brothers]]. As the story goes, Spider becomes more humble and responsible due to experiencing consequences for his actions for the first time in his life and learns how to care about other people, while Charlie learns how to be more confident and carefree and how to harness his own TricksterGod powers. [[spoiler: So by the end of the story, the twins are basically on equal footing. With [[HourglassPlot Charlie possibly being the more confident and magical out of the two now]], but still a far cry from the total opposites they were at the start.]]
207* In the ''Selerbergiada'' short stories by [[Literature/KronikiDrugiegoKregu Ewa Białołęcka]], [[MasculineGirlFeminineBoy Rita and Ricky]] von Selerberg are fraternal twins, and they can be mistaken for each other when seen from the behind. But while Rita trains dwarven box and hides her [[TomboyWithAGirlyStreak fashion-related interests]] (because she considers herself too unattractive to look anything but ridiculous in cute clothes), Ricky is definitely a lover, not a fighter - his main interests remain dating and music (dwarven metal, admittedly). Most of the time she's the mastermind behind whatever they do, while he just goes along and snarks.
208* ''Literature/XanaduStoryverse'': One short story describes a pair of twins, one a picture of politeness and courtesy around adults but wicked, false and demanding around other children while the other is sullen, quiet and stubborn but trustworthy, sincere and devoted to helping others. At the convention, the wicked twin had gone as an angel and the good one as a devil, but after the Change they only remain in these forms for a moment before they feel a pair of immense hands pick them up and set them down in each other's bodies.
209* ''Literature/ASongOfIceAndFire'':
210** Aerea and Rhaella Targaryen, the daughters of Aegon the Uncrowned. As children, Aerea was shy and timid, while Rhaella was bold and willful. Growing up, however, their personalities dramatically switched, as Aerea became a wild and outspoken girl, while Rhaella turned into a studious girl who devoted herself to religion by becoming a septa. Because of this discrepancy, there are rumors that the girls switched places when they attended their uncle Jaehaerys' coronation at Oldtown.
211** Baela and Rhaena Targaryen, Daemon's daughters with Laena Velaryon, were identical when they were young, but by the time they turned sixteen they no longer looked alike. Short-haired Baela was an energetic tomboy who loved to ride and fly, while long-haired Rhaena was a ProperLady who loved dancing. Baela was a warrior during the Dance of the Dragons and personally dueled Aegon II using her dragon, while Rhaena, who didn't get a dragon until she's come of age, mostly stayed out of the conflict.
212* In ''Literature/TheIckabog'', [[spoiler:the two baby Ickabogs at the end as they respond to how they're treated as they're born. The first hates humans as they were trying to kill it and its Icker. The second is friendly as things had calmed down when it was born a few minutes later]].
213* ''Literature/SweetAndBitterMagic'': Although [[AlwaysIdenticalTwins identical]], Tamsin and Marlena were very different otherwise. Tamsin is the most powerful witch in her generation, able to do spells with ease which exhaust others. Marlena though was very weak, and doing even simple spells put her in the infirmary, even into a coma. She grew to hate Tamsin for accidentally killing a friend of hers. Tamsin though had caused this as a result of a spell to save Marlena because of how much she loved her, which caused her to risk everything.
214[[/folder]]
215
216[[folder:Live-Action TV]]
217* ''Franchise/PowerRangers'':
218** Fraternal twins Madison and Vida Rocca, the Blue and Pink Rangers, from ''Series/PowerRangersMysticForce''. Madison is calm and thoughtful, V is on a permanent sugar high and goes rushing into things with a mad grin.
219** The Blue Ranger Theo Martin and his civilian identical twin brother Luen from ''Series/PowerRangersJungleFury''. Theo is calm, focused, and studious, while Luen is adventurous and outgoing.
220* ''Series/SisterSister'', with Tia and Tamera Mowry. SeparatedAtBirth, Tia is the mature, smart, and responsible one, while Tamera is irresponsible and BookDumb. Their characters in the Disney film version of ''Film/TWitches'' are basically the same.
221* ''Series/TwoOfAKind'' and ''Series/SoLittleTime'', both with Mary-Kate and Ashley Olsen -- the twins also played this up in most of their DTV movies as well. Mary-Kate typically played the wild and tomboyish twin while Ashley usually played the more responsible and more feminine sister.
222** One of the only times that this was ever reversed was in ''Winning London'' (the movie where they went to England), where Mary-Kate was Chloe Lawrence, a serious and competitive overachiever, while Ashley was Chloe's laid-back/fun-loving twin sister, Riley.
223* A few Creator/DisneyChannel shows:
224** ''Series/TheSuiteLifeOfZackAndCody'': Dylan Sprouse as jockish troublemaker Zack Martin and Cole Sprouse as nerdy Cody Martin. However, only the Tipton Hotel's ''Suite Life'' makes them this trope; in the spinoff series ''On Deck'', [[{{Flanderization}} they are more similar and realistic]]. (It has been said that each Sprouse twin is a better fit to the ''opposite'' Martin twin.)
225*** {{Lampshaded}} in "Grounded on the 23rd Floor":
226---->'''Zack:''' I swear, we're not related.
227** Also used in ''Series/LivAndMaddie'' and ''Series/IDidntDoIt''. Creator/PattyDuke herself would appear on ''Liv and Maddie'' [[ActorAllusion as the twins' grandmother and her own twin sister]].
228* ''Series/{{Friends}}'' gives us identical twin sisters Phoebe and [[Series/MadAboutYou Ursula]]. Phoebe is a (mostly) light-hearted and cheery {{Cloudcuckoolander}}, while Ursula is mean-spirited and thoughtless, and, in Phoebe's words, a "real high-powered, driven career-type" (she's a waitress).
229* The '80s sitcom ''Double Trouble'': Identical twins Jean and Liz Sagal (younger sisters of Katey Sagal of ''Series/MarriedWithChildren'') play identical twins Kate and Allison. Allison is serious and bookish; Kate is happy-go-lucky.
230* [[spoiler:BigGood Jacob and BigBad The Man in Black, Jacob's fraternal twin]] from ''Series/{{Lost}}''.
231* [[AlwaysChaoticEvil Jerome Valeska]] and his [[spoiler:identical twin Jeremiah]] are this in ''Series/{{Gotham}}''. Jerome is a LargeHam psycho, [[spoiler:Jeremiah is cold and meticulous]]. Their actor even compared them to a chainsaw and a scalpel.
232* ''Scoundrels'', Cal and Logan West, an incompetent burglar/criminal, and an intelligent defense lawyer, respectively. The characters are so different, you can barely tell they're played by the same actor.
233** This is a remake of a New Zealand show, ''Outrageous Fortune'', with Van and Jethro West in the same roles (also played by the same actor).
234* The good and evil brothers in ''Series/TheWanderer''. Despite both being played by Bryan Brown it isn't at 'all' difficult to tell Adam from Zachary, the evil cackle gives it away every time.
235* ''Series/{{iCarly}}'': Sam and Melanie Puckett. The former is almost permanently grouchy, borderline sociopathic, and sarcastic, while the latter is upbeat, outgoing, and perky. Notably, Carly says she can't believe that they're sisters. They agree.
236* Lee and Leah, the SeparatedAtBirth twins from the British teen show ''The Gemini Factor'', are a rebellious boy and a teacher's pet girl, with a sprinkling of TwinTelepathy. They also tended to wear black and white, respectively.
237* Katie and Emily Fitch from ''Series/{{Skins}}''. In the beginning, Katie is portrayed as the shallow, popular, boy-obsessed AlphaBitch, and Emily as the sweet, socially-awkward ShrinkingViolet (and closet lesbian) who does everything her bossy sister says until she comes out of the closet and begins dating her girlfriend Naomi. But when both girls suffer a series of [[BreakTheCutie severe personal setbacks]] they handle it very differently, with Katie gaining a lot more depth and maturity, having to hold the family together virtually on her own, and Emily becoming more and more angry and destructive.
238* Cathy and Patty Lane from ''Series/ThePattyDukeShow''. "But they're cousins, Identical cousins all the way. One pair of matching bookends, Different as night and day."
239** ''Series/{{SCTV}}'' parodied the show, running promos for "Identical Bellhops", "Identical Cheese Hostesses" and "Identical OPEC Oil Ministers", all shoehorning their titles into the familiar theme song.
240* Sutton and Emma on ''Series/TheLyingGame''. Sutton is a BookDumb RichBitch IceQueen AlphaBitch while Emma is sweet, caring and intelligent. The only things they have in common are a love for tennis and [[SiblingTriangle for Ethan]].
241* ''Series/TheBigBangTheory'' has Sheldon and Missy Cooper. Missy is an athletically built, charismatic, SouthernBelle whom their mother once described as being "dumb as soup." Sheldon is the page image for InsufferableGenius, a nerd, with NoSocialSkills to the point he does not understand typical human interaction.
242* Patricia and Piper Williamson from ''Series/HouseOfAnubis''. Patricia is the bold, [[TomBoy 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 Determinator]] sister is. It's pretty obvious when you compare their crushes - Patricia likes JerkWithAHeartOfGold Eddie, while Piper likes the NiceGuy ClassClown Alfie.
243* Max and Phoebe of ''Series/TheThundermans'' share only one trait: their superpowers.
244* ''Series/{{Bewitched}}'' had identical cousins Samantha and Serena. Sam was (mostly) happy maintaining [[{{Masquerade}} the Masquerade]] as a suburban housewife, while Serena was a wild party-girl who regularly abused her magic.
245* Jeannie and her sister on ''Series/IDreamOfJeannie''. Jeannie is a blonde who wears pink, and while she can be selfish and impulsive, is generally sweet and wants the best for Major Nelson. Her sister is a brunette who wears green and is a lot more malicious, self-centered, and sexually aggressive (constantly going after Tony, who's not interested), and causes a lot of problems whenever she shows up.
246* Turns out that every Spellman family member is born with a Polar Opposite Twin in ''Series/SabrinaTheTeenageWitch''. The most glaring example is Zelda and Jezebelda. Zelda is an intellectual who values knowledge and culture. Her twin, on the other hand, speaks like a SouthernBelle and describes herself as a "bad bad girl".
247* Protagonist Chip of ''Series/{{Baskets}}'' is creative, sensitive, and withdrawn but also bitter and pretentious, while his brother Dale is bombastic, charismatic, and optimistic but also cruel and competitive.
248* Saba's twins in ''Series/SavageKingdom'' are a curious, feisty female and a shy, laidback male. The latter's shyness works to his advantage when the twins come across a lioness. The more adventurous female is killed because she didn't hide as well.
249* ''Series/ControlZ'': The Alexander twin sisters are very different, as Sofia {{lampshaded}} in the first episode. Maria is nice, selfless, and more supportive, while Natalia is derisive, self-centered, and more independent.
250* ''Series/TheWilds'': Rachel and Nora not only look quite distinct, but they have very different personalities. In Rachel's case, she's a more outgoing athlete who's extremely focused on that and seems neurotypical. Nora has social anxiety from implied autism and is a shy, quiet, bookish girl overall.
251* ''Series/{{Himmelsdalen}}'': Helena is staid and more conservatively dressed. Siri is wilder, adventurous, with a more relaxed style. It turns out Helena is also neurotypical, while Siri's a sociopath.
252* ''Series/Scoundrels2010'': Cal and Logan are identical twins with contrasting personalities: Cal is a thuggish deadbeat who wants to become a career thief and conman like his father, while Logal is a professional and driven lawyer who doesn't want to get involved in crime.
253* In one episode of ''Series/ModernFamily'', Luke and Manny date a pair of identical twin sisters who basically had the same personalities as them, except the dumb one liked Manny and the smart one liked Luke. The boys wanted to switch to be with the more compatible sister but the girls refused, although they did offer to make out with them.
254* The main characters of ''Series/ComplicesAlRescate'' are the SeparatedAtBirth twins Silvana and Mariana. Silvana is the vain, snobby and bratty twin who was raised by her rich foster parents while Mariana is the humble, sweet and cheerful twin who was raised by her biological family in a very small town and is much poorer.
255* ''Series/{{Elementary}}'': The Ellison twins from "While You Were Sleeping". Rebecca Ellison is a kind-hearted woman that wanted to welcome her late father's illegitimate children into the family. Her twin sister Yvette is a selfish, ManipulativeBitch who was so determined to inherit everything that she killed the half-siblings and was plotting to kill Rebecca until Sherlock Holmes intervened.
256[[/folder]]
257
258[[folder:Myths & Religion]]
259* [[MasculineGirlFeminineBoy Artemis/Diana and Apollo]] from Myth/ClassicalMythology. She's associated with the wilderness and hunting, he's the god of arts and civilization. She protects girls; he protects boys. She eventually became associated with the moon and night while he got the sun and day. She made a vow of [[ChasteHeroine eternal chastity]], and he...[[ReallyGetsAround did not]]. They both have a connection to archery, however, and they both love their mother Leto. As Niobe unfortunately found out, they love her so much [[KnightTemplarParent they will kill people on her behalf.]]
260* Myth/HebrewMythology has Shachar and Shalim, the twin gods of dawn and dusk.
261* In Literature/TheBible, we have Jacob and Esau. Esau is the older one, and he displays a CarpetOfVirility and is [[ARealManIsAKiller a skilled hunter]]. Jacob is younger, isn't so hairy, and prefers to use his [[GuileHero brains over brawn]]. [[spoiler:This eventually enables him to receive Esau's birthright.]] 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. [[spoiler:They do manage to make peace... several years later.]]
262** According to Jewish tradition, Jacob's [[KissingCousins 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.
263* Nissien and Efnissien from the Mabinogion. Their names literally mean "peace" and "not-peace" which, funnily enough, highlights the main theme of the story. Not much is said of Nissien. His sociopath brother, on the other hand...
264[[/folder]]
265
266[[folder:Theatre]]
267* In ''The Venetian Twins'' by Carlo Goldoni, this trope is combined with theme of the accidental [[TwinSwitch twin switch]]. The twins are completely different in their way of acting and talking; one is considered well-mannered and intelligent, while the other is seen as tactless and [[TooDumbTolive stupid]].
268[[/folder]]
269
270[[folder:Tabletop Games]]
271* ''TabletopGame/DungeonsAndDragons'':
272** ''TabletopGame/ForgottenRealms'': A number of the gods in the pre-Fourth Edition setting are opposed siblings, although they usually look noticeably different -- Shar and Selûne (the moon and the dark), Tymora and Beshaba (good and bad luck), Vhaeraun and Eilistraee (drow thieves, often male, and redeemed drow, often female).
273** ''TabletopGame/{{Ravenloft}}'': Laurie and Gennifer Weathermay-Foxgrove are identical twin monster-hunters and proteges of Rudolph van Richten. Laurie is an exuberant tomboy, fencer, and pistoleer who dresses like a man, while Gennifer is a demure, sober-minded wizard with closets full of conservative dresses. [[spoiler:Also, Gennifer may be an unwitting lycanthrope.]]
274* ''TabletopGame/WarhammerFantasy'': The elves really seem to be prone to this trope.
275** The High Elf heroes Tyrion and Teclis are identical twins with radically opposing personalities and skills. Tyrion is proud, fair, noble, athletic, and well-spoken, while Teclis is dark, feeble, scholarly, caustic-tongued, and bitter. The one is the greatest warrior and commander of his race but has no talent for sorcery, the other is a poor fighter but [[TheArchmage the most powerful living wizard in this age of the world]].
276** 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.
277** The Wood Elves have Naestra and Arahan, polar opposite personalities in identical bodies produced when Naestrahan was split into two women due to an unknown event deep in the woods of Athel Loren. Naestra is peaceful, kind and compassioante, while Arahan is wild-tempered and aggressive, and revels in death and battle.
278[[/folder]]
279
280[[folder:Toys]]
281* Not ''technically'' twins, but Toys/MonsterHigh has Jackson Jekyll and Holt Hyde, complete opposites who share a body. While Jackson is quiet and nerdy, Holt is outgoing and upbeat. They even used to have a "night and day" system of who was the one in control, although that has since changed.
282* The ''Toys/{{Bratz}} Twins'' characters Phoebe and her identical twin Roxxi are this way. Phoebe likes soft colours and dresses poppy while her sister Roxxi likes dark colours and dresses punkish. Their jingle even calls them "Sweet and spicy".
283* Skyburst and Stormclash, twin sisters from ''Franchise/{{Transformers}}''. Skyburst is a pacifist who only engages in combat when absolutely necessary after all other solutions have failed, Stormclash is a ruthless warrior whose only response is to fight and show no mercy.
284[[/folder]]
285
286[[folder:Video Games]]
287* Django and Sabata from ''VideoGame/{{Boktai}}'' fit this trope perfectly: not only do they have opposite demeanors, but their powers are the exact opposite of one another.
288* The titular VideoGame/{{Cuphead}} is known for being the hot-blooded, courageous, and sometimes devious older twin brother. [[http://kingfeatures.com/licensing/licensed-brands/cuphead/ "A shoot-first-and-ask-questions-later type of guy."]] Mugman is known for being the good-humored, industrious, and rascally younger twin brother. "Calculated in battle and a tricky adversary." While both of them have a rebellious streak, Mugman does try to stop Cuphead when the latter gets too overconfident when betting against the Devil.
289* The fourth installment of ''VideoGame/DetectivesUnited'' introduces Agent Dorian Brown's EvilTwin, Mortimer. Mortimer is calculating, self-serving, and perfectly willing to use or hurt other people to get what he wants. Dorian is honest, loyal, strives to do the right thing, and will defend those closest to him to the death if need be.
290* The ''VideoGame/DevilMayCry'' series has [[RedOniBlueOni hothead Dante and calculating Vergil]].
291* ''VideoGame/DragonAgeII'' has [[PlayerCharacter Hawke]]'s younger brother and sister, fraternal twins Bethany and Carver. Carver is a tall, burly swordsman with an abrasive and somewhat irritable personality. Bethany is a petite mage and is gentle, sweet-natured, and friendly to everyone. They even have opposite feelings toward their elder sibling; each companion in the game has a relationship meter, and Bethany's starts with a heavy tilt toward the friendship end, while Carver's starts with a heavy tilt toward the rivalry end. The game itself also draws attention to their RedOniBlueOni personalities, as the background of Carver's icon is a reddish-brown while Bethany's is a vivid blue.
292* ''VideoGame/EldenRing'' has several sets.
293** Malenia and Miquella. Malenia is a redheaded StatuesqueStunner of an ActionGirl who's best known for her unparalleled swordplay, while Miquella was blonde and a NonActionGuy as he was cursed to eternal childhood, but was TheArchmage and an excellent inventor. The two work together to support Miquella's plan to become a full god and nurture the Haligtree as a home for those outcast from the Golden Order.
294** There's also Mohg and Morgott, the Omen twins. You wouldn't know the two were related just from seeing them together, as Mohg barely looks humanoid while Morgott looks like a tall human with horns sprouting around his body. Morgott is also a staunch supporter of the Golden Order despite its hatred for Omens and currently being in shambles, while Mohg has embraced the defilement he was born into and worships an Outer God called the Formless Mother, and with her aid created BloodMagic.
295* ''VideoGame/TheElderScrollsVSkyrim'' has fraternal twin brothers Vilkas and Farkas in the Companions guild, who are a combination of this trope and RedOniBlueOni. Vilkas is very intelligent but abrasive, hot-blooded, and not especially friendly to new arrivals. Farkas is generally regarded as being dumb muscle, but much more laid back, difficult to anger, and sweet-natured. They are both good people, however, and they love each other and their guildmates.
296* ''Franchise/FinalFantasy'' series:
297** ''VideoGame/FinalFantasyIV'': Palom and Porom. Palom is the bouncy, mischievous user of black magic, and Porom is the serious-minded user of white magic.
298** ''VideoGame/FinalFantasyVI'': Edgar and Sabin Figaro. Edgar is smart, TheStrategist, and a GadgeteerGenius, while Sabin is not much of a thinker and prefers to act with his hands since he's an incredibly powerful martial artist.
299** ''VideoGame/FinalFantasyXIV'': [[{{Deuteragonist}} Alphinaud]] and Alisaie Leveilleur. Both are TheAce, but he is more levelheaded and diplomatically inclined, while she is HotBlooded and prefers [[LeeroyJenkins a more direct approch]].
300** ''VideoGame/WorldOfFinalFantasy'': Lann and Reynn. Lann is bright and energetic, while Reynn is calm and calculated.
301** ''VideoGame/FinalFantasyDimensions'' contains gender-swapped [[{{Expy}} Expies]] of these characters in soft-spoken, serious white mage (at game start) Dusk and his snarky, energetic black-magic-using (again, at game start) twin sister Alba.
302* ''Franchise/FireEmblem'':
303** Edain and Brigid from ''VideoGame/FireEmblemGenealogyOfTheHolyWar''. Edain is a sweet WhiteMagicianGirl who didn't train as an ActionGirl because it simply didn't fit her kind nature, while Brigid is a stubborn {{Ladette}} that was first kidnapped and then raised among pirates.
304** ''VideoGame/FireEmblemTheBindingBlade'' introduces another pair in Lugh and Raigh. Lugh is a [[CheerfulChild cheerful]] mage (specializes in elemental magic), while Raigh is a cold and calculating shaman (specializes in dark magic).
305** ''VideoGame/FireEmblemFates'' features ''two'' sets, though they're actually non-identical in both cases:
306*** Nohr natives [[NinjaMaid Felicia and Flora]] are more adept at combat and housework, respectively. When push comes to shove, Felicia's loyalty is to Corrin, while Flora's loyalty is to her tribe.
307*** From Hoshido, Kaze is fairly calm and collected, while Saizo is more HotBlooded and blunt. Kaze becomes one of Corrin's closest allies in all three routes, while Saizo distrusts Corrin in the two routes in which he joins. Fittingly, [[RedOniBlueOni Saizo's hair is red and Kaze's is green]].
308* Saku and Bo from ''[[VideoGame/DotHackGU .hack//G.U.]]'' are twins taking turns playing one character, Sakubo. You can tell who's logged on by the character's eyes (Saku has TsurimeEyes, Bo has TaremeEyes), hat (Saku has the "sun" side pointing up, Bo has the "moon" side), and [[RedOniBlueOni their general attitude towards you]].
309* The ''Manga/GetBackers'' game ''Jagan Fuuin'' has the Mikado twins: Daisuke is very compassionate and sweet and easily befriends the main cast, whereas his identical twin Kyosuke is cold, emotionless, rarely speaks, and seems robotic. It's eventually revealed [[spoiler:that the twins are the same person, namely Kyosuke, who, due to fear of their immense spiritual power, were split into two entities, the "body" and "soul". Daisuke is the soul, and once they're merged back into Kyosuke, he acts much like his "brother" did]].
310* Sven and Grancy from ''VideoGame/{{Gyee}}''. Sven is HotBlooded, outgoing, and passionate person who has fire powers and is classified as a Warrior. Grancy is calm, stoic, DeadpanSnarker, and is a Mage who uses ice powers. Sven has black hair with a red streak, while Grancy has white hair with a blue streak.
311* Felix and Ted Huxley from ''VideoGame/Kindergarten2''. Felix is a pint-sized RichBastard who constantly belittles and bosses around his brother [[spoiler:and is planning to have him murdered so he won't have to share his inheritance]]. Ted on the other hand is [[NiceGuy far more pleasant]], but is also an ExtremeDoormat to his brother and so desperate to [[WellDoneSonGuy win his and their father's approval]] that he's willing (though reluctant) to go along with Felix's plan to murder one of their classmates, even though he doesn't even know ''why'' said classmate needs to die beyond vague reasons of "inheritance" and "for the good of the company".
312* ''VideoGame/MOTHER3'': Lucas is [[ShrinkingViolet shy and withdrawn]], while Claus is [[HotBlooded rash and reckless]].
313* The ''Franchise/{{Neptunia}}'' series has the extrovert Ram and the shy Rom. These twins are also a huge source of [[AnnoyingYoungerSibling irritation]] for their big sister, Blanc.
314* In ''VideoGame/PathfinderKingmaker'' Kanerah and Kalikke are identical tiefling twins. Kalikke is idealistic and dreamy, ChaoticGood, [[MakingASplash controls water]], and can [[EmpathicHealing heal others at a cost to herself]]. Kanerah is pragmatic and ambitious, LawfulEvil, [[PlayingWithFire controls fire]], and empowers herself by [[YourSoulIsMine torturously offloading the cost of her abilities onto dead souls]]. Due to peculiar magical circumstances, they're rendered unable to exist simultaneously, communicating only through notes, and one of them comments this has the benefit of preventing them from constantly fighting.
315* Andrey and Peter Stamatin from ''VideoGame/{{Pathologic}}'' and its sequel/remake are a classic RedOniBlueOni. They're both architects who have worked together on many of the town's structures, but Andrei is a more social person who runs his own bar, is hedonistic, and has a somewhat hot temper; Peter, on the other hand, is depressive, tends to keep to himself, and gets drunk on the town's version of alcohol.
316* Yu and Rei, the ghost twins from ''VideoGame/PuyoPuyo''. Yu is a loud, pun-spouting GenkiGirl while Rei is quiet and depressed. [[spoiler:It's implied their personalities were vice versa when they were alive.]]
317* The Ryō twins from ''VideoGame/SenranKagura''. Ryōbi is a {{sadist}} who hates [[ACupAngst her flat chest]], whereas Ryōna is a masochist who loves [[BigBreastPride her large rack]].
318* ''VideoGame/TheSims2'':
319** In Strangetown there's Lola and Chloe, in the Singles household, although [[ContinuitySnarl whether or not they are actually twins is somewhat debatable]]. Lola is MarriedToTheJob, while Chloe is a HardDrinkingPartyGirl.
320** The Davis twins from the ''University'' expansion are described as "different as night and day" within the game, yet they actually have identical personalities and aspirations. The only real difference between them is their appearances and what they like to talk about. Similarly, the Pleasant twins in Pleasantview are supposedly very different but have very similar personalities.
321* ''Franchise/StreetFighter'': Hyperactive Yun and brooding Yang of the Lee Brothers.
322* The titular ''Franchise/SuperMarioBros''. Mario is brave, outgoing, and HotBlooded; Luigi is reluctant, timid, and shy.
323* The Bruiser Brothers in ''Super VideoGame/PunchOut''. Rick Bruiser is outgoing and hot-blooded, while Nick Bruiser is quiet and cold.
324* The Yorigami sisters from ''Franchise/TouhouProject''; Jo'on is prideful and domineering while Shion is gloomy and pessimistic. Jo'on can steal other people's wealth and fortune for herself while Shion causes everyone around her to suffer misfortune, including herself.
325* Greg and Sidney Kasal from ''VideoGame/TraumaCenter''. Sidney is serious and straight-laced, while Greg is far more relaxed.
326* In ''VideoGame/UntilDawn'', Beth is blunt, cautious, and responsible, compared to her twin sister Hannah, who is naive, sensitive, and impulsive.
327* ''VideoGame/VampireTheMasqueradeBloodlines'': The Voerman sisters, stoic businesswoman Therese and emotional party-girl Jeanette. You eventually discover that [[spoiler: this trope is subverted. Therese is a Malkavian, a member of a clan of vampires known for insanity, and her "sister" Jeanette is actually her SplitPersonality developed to cope up with her father's abuse that cranks up to eleven due of being a Malkavian means worsening one's existing mental health issues. With [[TalkingTheMonsterToDeath high enough Persuasion skill]], you can convince the "sisters" to cooperate instead of one "killing" the other.]]
328* The ''VideoGame/WarCraft'' universe has Malfurion and Illidan Stormrage, the night elf twin brothers. The former leads his people to druidism as an alternative to the dangerous magic that brought the [[LegionsOfHell Burning Legion]] to Azeroth. The latter insists on tapping both that magic and the power of the demons themselves, is imprisoned for centuries, and eventually becomes an EvilOverlord.
329* Calvin and Sam from ''VideoGame/WhatRemainsOfEdithFinch''. Calvin wants to be an astronaut, and Sam a soldier.
330* ''VideoGame/XenobladeChronicles2'': Pyra is a RoseHairedSweetie [[SilkHidingSteel with a surprising strength]]. Mythra, her other personality, is a tough warrior girl [[{{Tsundere}} who can be surprisingly tender]]. [[spoiler:This was, in fact, intentional. Mythra was the original personality, and was so horrified when she destroyed three Titans (killing many of her friends in the process) that she created Pyra to be everything she wasn't]]. Pyra is even an [[SupremeChef excellent cook]] when Mythra is [[CordonBleughChef aggressively terrible]].
331* ''VideoGame/XenobladeChronicles3'': Segiri (Number 7) is TheStoic who speaks exclusively in RoboSpeak, but is ultimately an excellent leader who wants what is best for everyone. Number 13 is an AffablyEvil BloodKnight [[IWorkAlone Lone Wolf]] who doesn't care about anyone besides Segiri. For bonus points, no one even knows what twins ''are'' due to being born from {{Uterine Replicator}}s; everyone is rather confused that the two look identical, and their opposing personalities just confuse them more.
332
333[[/folder]]
334
335[[folder:Visual Novels]]
336* Dahlia Hawthorne and Iris from ''VisualNovel/PhoenixWrightAceAttorneyTrialsAndTribulations''. Dahlia is [[spoiler:a ruthless sociopath who has been using her cute and innocent image to get away with murder, literally, for years]] and Iris is [[spoiler: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]].
337* ''VisualNovel/{{Clannad}}'': Kyou and Ryou. Long-haired {{tsundere}} and short-haired, easily-embarrassed sweetheart.
338* ''VisualNovel/HigurashiWhenTheyCry'': Mion and Shion Sonozaki. Mion is [[{{Tomboy}} assertive]] and [[LargeHam bombastic]], the leader of her TrueCompanions; Shion is sly and [[TheTease seductive]], preferring to [[{{Troll}} manipulate people subtly]] rather than openly command them. It's even more odd when you realize that [[spoiler:they're acting like each other, thanks to a TwinSwitch they made when they were younger.]]
339* ''VisualNovel/{{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 [[spoiler: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 [[RapeAsBackstory Kohaku]]), so Hisui buried her emotions to help Kohaku stay stable while Kohaku hid her very darkened TrueSelf behind a facade of happiness.]]
340** Averted in ''Flower of Thanatos'' side story, where Kohaku and Hisui synchronize to the point where they are no longer themselves and their personalities fuse into one. Becoming SingleMindedTwins instead.
341* Ember and Daystar in the ''ComicBook/ElfQuest'' visual novels. Ember is active, bold, and like her name in looks and attitude. Brother Daystar is mystical and calm, and blond with pale skin.
342* ''VisualNovel/LittleBusters'' has [[spoiler:Haruka and Kanata]], who form an AllWorkVsAllPlay duo. In reality, though, these roles were mainly either in response to or outright enforced by [[spoiler:their abusive extended family and in the end when they are able to move on from their past and accept one another as friends their personalities become a lot less extreme. Not entirely, though.]]
343* ''VisualNovel/EfAFairyTaleOfTheTwo'': The Shindou sisters. Chihiro is an [[TheIngenue ingenue]], Kei is a {{Shorttank}}.
344* The Kazato twins from ''VisualNovel/IfMyHeartHadWings''. Asa is the timid one, and Yoru is the blunt one. [[ThemeTwinNaming Their differences in personality are literally night and day.]]
345* ''VisualNovel/TokimekiMemorial 2'' has the twin sisters Miho and Maho Shirayuki. Miho is a sweet, daydreaming girl who believes in fairies, loves [[FortuneTeller fortune-telling]] and plushies, and dreams of becoming a scenario writer of stories for children. Maho is a playful, blunt, and mischievous street-wise girl, who enjoys [[TheFashionista fashion]] and window-shopping, and dreams of becoming a model.
346* The Prince of ''VisualNovel/LadykillerInABind'' is a largely asexual, [[InsufferableGenius highly educated]], callous ManipulativeBastard. The Beast, his [[HalfIdenticalTwins Half-Identical Twin]] sister - who has to [[TwinSwitch take her brother's place]] for a week - is much more affable, ''extremely'' flirtatious, and pretty BookDumb.
347* ''VisualNovel/SuperDanganronpaAnother2'' has the Otonokoji sisters. Hibiki is brash, outspoken, and feisty, while Kanade is more submissive, friendly, and gentle-hearted. Additionally, Kanade proves to be quite helpful and insightful during Class Trials, while Hibiki isn't initially willing to trust anyone but gradually warms up to her classmates. [[spoiler: Chapter 3 later reveals just how deep it runs: Hibiki is really a kind girl who genuinely loves and cares for her sister, while Kanade is revealed to be an utterly remorseless {{Yandere}} who's spent years making her "inferior" twin sister emotionally dependent on her. Namely by mentally abusing her and killing everyone who she feels gets too close to Hibiki.]]
348[[/folder]]
349
350[[folder:Web Animation]]
351* ''WebAnimation/MoniRobo'': [[https://www.youtube.com/watch?v=SSntJF1JM6w Mayuko and Mayuka]] are twins with opposite personalities. Mayuko is an active, sporty girl while Mayuka is a smart, quiet girl. They're still opposites even after their mother Akane divorced their father Yoshiichi and took Mayuka with her: Mayuko became more diligent on helping her dad with the chores and raising her grades, while Mayuka [[spoiler:became a delinquent after her mom neglected her for so long.]]
352* In ''WebAnimation/RedVsBlue'', North is a relatively NiceGuy who is more than willing to put himself in harm's way to save others, while South tends toward ChronicBackstabbingDisorder, [[spoiler:with tragic results for her brother]].
353[[/folder]]
354
355[[folder:Webcomics]]
356* ''Webcomic/ItsWalky'': Fraternal twins Beef and Walky. Justified as Beef was actually switched at birth with Walky's real twin Sal as part of Mrs. Walkerton's SeparatedAtBirth gambit, Sal and Walky later, after the truth was uncovered, and used to set up some NotSoDifferentRemark moments between the two of them.
357** Sal and Walky again in ''Webcomic/DumbingOfAge'' despite not being raised apart this time around.
358* ''Webcomic/LnM'': L is energetic and childish, M is laid back and precocious.
359* Sikue and Tatsuma in ''Webcomic/BeyondBloom'', 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.
360* Gogo and Didi from ''Webcomic/{{Bomango}}''. Gogo is a BoisterousBruiser with a [[HairTriggerTemper short fuse]], a heterosexual {{Ladette}}, and a JerkWithAHeartOfGold who acts as TheId in their FreudianTrio (Andy is TheEgo). Didi is a polite perky scientist and a LipstickLesbian who acts as TheSuperEgo. 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.
361* Subverted in ''Webcomic/CursedPrincessClub''. While Gwendolyn and her twin brother Jamie couldn't ''look'' more different from each other (she's a [[FaceOfAThug creepy goblin-like girl]], he's a pink-haired PrettyBoy), they are both equally sweet, kind, and supportive.
362* Played with in ''Webcomic/EnnuiGo''. 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. Meanwhile, both of them stand in contrast to Izzy's clone Kirsty, who is a GenkiGirl and lacks their cynical attitudes. [[spoiler:This is justified by the cloning process didn't include Izzy's [[DarkAndTroubledPast memories]].]]
363* ''Webcomic/ElGoonishShive'':
364** Elliot and his OppositeSexClone Ellen are very different from each other. Elliot is reserved, shy, and is naïve to a ridiculous degree. Ellen is brash, worldly, and outgoing. Justified since Ellen has tried to distance herself from Elliot's memories, and she also had an entire lifetime's worth of experience from an AlternateDimension implanted in her head.
365** Susan is a nerdy asexual introvert while Diane is a bisexual LovableAlphaBitch. Justified since they weren't raised together and [[spoiler:aren't actually twins; they're distantly related through an immortal elf and only happen to be identical to each other due to destiny or magical shenanigans or elsewhat]].
366* Molly and her clone/twin Galatea in ''Webcomic/TheInexplicableAdventuresOfBob'' were raised separately. Both are brilliant, naive, and devoted to Bob, Jean, and each other. But while Molly is upbeat, friendly, and gentle, Galatea is paranoid and megalomaniacal.
367* ''Webcomic/TheOrderOfTheStick'' has Elan and Nale, who look the same except for [[BeardOfEvil a goatee]] on Nale, but their personalities are the complete opposite. Elan is good, naive, and GenreSavvy, while Nale is evil and scheming. [[http://www.giantitp.com/comics/oots0725.html It turns out]] that Elan got his goodness from his mother and his genre savviness from his father, while Nale got his evilness from his father and his ComplexityAddiction from his mother. Their opposite is also indicated by [[SdrawkcabName their names]].
368* ''Webcomic/{{Realta}}'': The Gemini twins. Fletcher is cheerful and gregarious, while Milo is more serious.
369* The Hong twins in ''Webcomic/SharpZero''. Elliot is dorky, unorganized, and believes others see him as [[TheUnfavorite the evil twin]] and a screw-up. Marcus is the put-together Mom Friend was a straight-A student, and never gets in trouble.
370* ''Webcomic/SleeplessDomain'': Forte Bass (aka Gail) and Outrageous Apple. Bass has music-based powers, is pretty modest, and is mute, while Apple runs on a rebel/punk/fruit theme, uses her skateboard to attack, is loud and brash, and speaks enough for both of them. Oddly enough, they both still have red as their magical girl color.
371* ''Webcomic/{{Unsounded}}'': The Gefendur gods are two pairs of very different twins. Riv is a violent macho manly man while his twin Baelar is a quiet warrior scholar and poet. Yerta is a plump, loving fertility godess who loves creating life while her twin Tirna is a skinny wrathful trickster who doesn't understand the appeal of imprefect living things.
372* ''Webcomic/WelcomeToRoom305'' has the HotBlooded [[TheLadette ladette]] Yoona as the older twin to Yoon Sung, a ([[NotSoStoic normally]]) [[TheStoic stoic]] young man. As young children, Yoona was a tomboy while Yoon Sung was a sensitive crybaby. Both twins have tempers when they want to though.

376* Creator/{{Amoridere}}:
377** [[http://nazr.in/1eTm Doki]] is much different than her twin sister [[http://nazr.in/1eTn Toki.]] 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. It was also noted that, when the two were children, Doki was always the shy one, while Toki was more assertive.
378** [[http://nazr.in/1eTo Brownie]] is very much different than her sister, [[http://nazr.in/1eTp Brittani,]] in that Brittani is described as being prim and proper, while Brownie is described as tomboyish. Apparently, them looking different than one another is supposed to reflect that.
379** Website/{{Killerbunnies}}: [[http://nazr.in/1eTq Kamu and her twin sister Kanran]] are somewhat similar in some personality traits, however, Kamu can be said to be more levelheaded and is typically polite whenever needed, whereas Kanran is typically gluttonous, rude, and usually acts before thinking, making her rather foolish. Likewise, [[http://nazr.in/1eTr Miren and Citrine,]] with the former being described as being "LeanAndMean" and the latter being "bright and bubbly".

383* Vex and Vax from ''WebVideo/CriticalRole'' play RedOniBlueOni to each other. [[Creator/LauraBailey Vex]] is [[GenkiGirl excitable]], [[TheCharmer flirtatious]], and [[HotBlooded emotional]]. While [[Creator/LiamOBrien Vax]] can be all these things in the right contexts, he's more prone to being [[TheStoic composed]], [[DeadpanSnarker sarcastic]], and [[PragmaticHero pragmatic]]. The twins love each other dearly, though. [[spoiler:They also become champions of gods that are practically night and day -- Vax under the god of death, the Raven Queen, and Vex under the god of the sun, Pelor.]]

386[[folder:Western Animation]]
387* ''WesternAnimation/AmericanDragonJakeLong'': Oracle twins Kara and Sara (pictured). The gothic Kara foresees good events in the future and is always gloomy because everything good about to happen gets spoiled for her, while cheerful and preppy Sara foresees the bad events and is always so happy because any time the horrible things she sees ''aren't'' happening is absolutely fantastic in comparison.
388* ''WesternAnimation/TheAngryBeavers'': Dagget and Norbert, twin beavers, the latter of whom is sensible and collected and the former of whom is essentially insane.
389* In ''WesternAnimation/BoJackHorseman'''s ShowWithinAShow, ''Mr. Peanutbutter's House'', the titular character adopts human twins Zoe and Zelda; the former is outgoing and cheerful, while the latter is sullen and brooding. It became an InUniverse [[MemeticMutation meme]] in the show's fanbase to classify people as either "Zoes" or "Zeldas" depending on their outlook and personality.
390* ''WesternAnimation/TheCrampTwins'': Lucien is smart and highly responsible, with a keen interest in nature; while Wayne is a mischievous prankster and bully who is scared of animals.
391* ''WesternAnimation/CatDog'': Cat and Dog, ConjoinedTwins who are essentially the opposite of each other. Cat is sophisticated, risk-avoidant, and short-tempered. Dog is uncultured, reckless, and chipper.
392* WesternAnimation/PixarShorts: ''WesternAnimation/DayAndNight'' actually took this literally, featuring an encounter with two traditionally-animated figures, through which views of a CGI world during different times of the day can be seen.
393* ''WesternAnimation/DragonTales'': Zak and Wheezie, who are even very different colors despite being conjoined. Zak is green and uptight, while Wheezie is purple and a GenkiGirl.
394* ''ComicBook/ElfQuest'': Suntop and Ember actually brought CBS down on them when their creators tried to get an AnimatedAdaptation going. Turns out {{Saturday Morning Cartoon}}s is not the time to reverse gender roles and have a spunky little girl and a mild, intuitive little boy. Or, for that matter, parents with different skin colors.
395* ''WesternAnimation/TheFairlyOddParents'': Timmy's more serious and responsible fairy godparent Wanda has a twin sister named Blonda who's a fun-loving TV star.
396* ''WesternAnimation/FreakyStories'' features a story about a pair of twins who take advantage of their wildly different interests in talents by using TwinSwitch to appear to be one perfect person.
397* ''WesternAnimation/KimPossible'': Gemini identifies himself as being opposite his twin sister Dr. Director in every possible way, which is mostly accurate. They don't even look much like siblings, let alone twins.
398* ''WesternAnimation/{{Kaeloo}}'': Rabbit sisters Pretty and Eugly. Eugly is a kind, friendly GonkyFemme, and Pretty is a beautiful yet selfish and manipulative AlphaBitch who is hated by the rest of the cast.
399* ''WesternAnimation/TheLoudHouse'' has identical twin sisters [[TomboyAndGirlyGirl Lana and Lola]]. Lana's masculine, tomboyish, and [[FilthyFun loves getting dirty]], whereas Lola [[PrincessPhase dresses like a princess]], regularly competes in beauty pageants, and is far more conceited than her twin.
400* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
401** Pinkie Pie and her fraternal twin sister, Marble Pie. Pinkie Pie is bright pink, exuberant, and outgoing, while Marble Pie is a dull gray, reserved, and very shy.
402** According to the [[ComicBook/MyLittlePonyFriendshipIsMagicIDW IDW Comics]], the mild-mannered schoolteacher Cheerilee has an identical twin sister named Cherry Blossom who's a professional wrestler.
403* ''WesternAnimation/{{Muppet Babies|1984}}'': Scooter and Skeeter. The former is a socially awkward computer nerd, the latter an energetic {{tomboy}} who likes sports. They sang a song dedicated to this in the episode about opera, as seen in the quotes section.
404* ''WesternAnimation/RazzberryJazzberryJam'':
405** The Drum Brothers, Buddy and Krupa, are about as different as night and day- a fairly apt metaphor, as Buddy is cheerful and sunny, while Krupa is gloomy (and snarky).
406** There’s Bonita and Woody from “A Bonnie Tale”. Bonita is stuffy, uptight, and dislikes improvisation, and while Woody is never actually seen, from the way the Jazzberries talk about him he’s cool, fun to hang around with, and has a tendency to make up stories about his supposed adventures (which Bonita hates).
407* The Interesting Twins From Beneath the Mountain from ''WesternAnimation/CodenameKidsNextDoor'' come off as [[CreepyTwins creepy]], SingleMindedTwins at first, but after a series of failures, their personalities shine through: the female twin is hot-tempered, commanding, and impulsive, while her brother is calmer and more likely to go along with her plans (he is fiercely protective over her when she's upset, however). Plus, the birthmarks on their face make them a literal example of SiblingYinYang.
408* ''WesternAnimation/TheVentureBrothers'': Thanks to DivergentCharacterEvolution - Dean has slowly become a nervous, cowardly NonActionGuy while Hank has evolved into a SmallNameBigEgo who [[TooDumbToLive leaps into danger]] at the slightest provocation.
409** Also bitter, unsuccessful, frail Rusty and the much more skilled and charismatic JJ. It is implied that JJ got all the best DNA from their father, despite having spent decades as Rusty's [[BodyHorror conjoined foetal twin]].
410* ''WesternAnimation/GravityFalls'':
411** The series has [[AdorablyPrecociousChild smart, serious Dipper]] and [[GenkiGirl ditzy, energetic Mabel]].
412** It's later revealed that [[spoiler:Grunkle Stan was also a twin. [[BrainsAndBrawn His brother, the real Stanford Pines, was a genius, while Stanley was a laid-back oaf.]] While they had a close relationship as kids like their niece and nephew, their different interests eventually separated the two. Fortunately, they end up making amends in the series finale.]]
413* ''WesternAnimation/YinYangYo'' has [[BadassBookworm smart]] NeatFreak Yin and her [[BookDumb less intelligent]] [[BloodKnight violence loving]] brother, Yang. [[MeaningfulName No wonder their names are literally]] [[SiblingYinYang Yin and Yang.]]
414* ''WesternAnimation/SofiaTheFirst'': Prim and proper reserved Amber who is prone to flights of fancy with her down-to-earth practical casual funloving brother James.
415* ''WesternAnimation/GrojBand'' has brothers Kin and Kon Kujira, who are a diminutive GadgeteerGenius and a FatIdiot respectively.
416* {{Downplayed}} on ''WesternAnimation/TheSimpsons:'' [[ObnoxiousInLaws Patty and Selma]] are similar in their chain-smoking, raspy voices and dislike of Homer; but Selma has married about a half-dozen times, while Patty initially [[DoesNotLikeMen seemed uninterested in romance]]. Since then, she's come out as a lesbian, though still isn't as quick to commit as Selma.
417* ''WesternAnimation/MiraculousLadybug'':
418** A pair of identical cousins Adrien and Félix. Adrien is an ExtremeDoormat but he's a genuinely sweet kid and a NiceGuy with NoSocialSkills due to [[LonelyRichKid his lonely rich kid's upbringing]], while Félix is a {{Jerkass}} ManipulativeBastard and possible [[TheSociopath sociopath]]. Even their appearances contrast - Adrien keeps his hair wavy and wears casual clothes most of the time, while Félix has more carefully combed hair and wears a vest and tie.
419** Émilie (Adrien's mother) and Amélie (Félix's mother) are implied to be twins, but while Émilie was (as far as anyone knows) a genuine NiceGirl who was close with both [[HappilyMarried Gabriel]] and [[GoodParents Adrien]], Amélie is a BitchInSheepsClothing with a disturbing LackOfEmpathy, as she mocks Gabriel for still wearing his wedding ring (even though she herself lost her husband at some point after Émilie's disappearance, not to mention that Émilie is, again, ''her twin sister'') and encourages Félix to become [[DaddysLittleVillain Mommy's Little Villain]].
420* ''WesternAnimation/{{Ninjago}}'': The Hands of Time are definitely this.
421** Kru is old because he has been waiting forty years for his twin. He hates modern technology but admits that it has its uses, and at least tolerates his brother's love for what he hates. His powers are Reverse and Pause, for which the colors are copper/yellow and red. He's the brains and the calmer of the two but can fight on his own, even without his powers.
422** Acronix is young, having traveled forty years into the future. He loves modern technology but is willing to return the old ways in life for Krux, though not without trying to get him to like technology. His powers are Forward and Slo-Mo, for which the colors are green and blue. He is the more excitable and brawny of the two but still able to understand technology within just a few days after his return. He's also quite adaptive, especially in battle.
423** In the past, their outfits are even inverted versions of each other. In the present, they've undergone different CostumeEvolution. Krux's is darker and more faded in coloration (since it's forty years old), and has an hourglass with a chain printed on his left torso and right leg, but was already there when Acronix returned. Acronix's is brighter and more vibrant in coloration just like it was in the past (since it hasn't had forty years in which to fade) and later has a phone with green earbuds attached printed on his right torso hand left shoulder. Acronix's hair is long and black while Krux's is white (formally black) and short. Krux has a mustache while Acronix has a beard. Krux has a pocket watch that is rarely seen outside his disguise, while Acronix has a smart watch that is constantly seen on his wrist.
424* ''WesternAnimation/StrawberryShortcake: Berry Bitty Adventures'' has Sweet and Sour Grapes. As their names indicate, Sweet is cheerful and friendly. Sour is crass and sometimes downright mean, particularly in situations where she's reminded that she and Sweet are twins. Both are bakers, but Sweet favors, well, sweet dishes, whereas Sour focuses on savory dishes. {{Lampshaded}} in their first appearance.
425-->'''Strawberry:''' They don't look much like twins.\
426'''Lemon:''' I don't think they ''want'' to.
427* ''WesternAnimation/TotalDrama'': Amy and Samey are identical twins. Amy is an AttentionWhore and a ManipulativeBitch, whereas Samey is an ExtremeDoormat yet also TheHeart of her team. Amy goes out of her way to make trouble for her sister and treats her like a servant, while Samey just wants to get out from under her sister's thumb and become more confident in herself.
428[[/folder]]
429
430[[folder:Real Life]]
431* ''Series/AmericasNextTopModel'': Amanda and Michelle Babin, who were contestants on Cycle 7. Michelle is tomboyish and more outgoing, whereas Amanda is more feminine and introverted. Michelle also came out of the closet during the course of the show, just to add another night and day difference to the mix.
432* Nikki and Brie, the Wrestling/BellaTwins of ''Series/TotalDivas'' and WWE fame. Brie is a GranolaGirl, who loves being a hippie and CountryMouse - but also is a HardDrinkingPartyGirl. Nikki is TheFashionista and powerlifter, who loves anything expensive - while preferring wine and desserts to excessive drinking. Their workout methods are different, with Brie opting for yoga and cardio while Nikki enjoys powerlifting to maintain AmazonianBeauty.
433* ''Music/TokioHotel'': Bill and Tom Kaulitz are identical twins, but (among other things) they dress and wear their hair differently, to the point that some people don't believe they're identical. One of the more notable differences is Bill's focus on "true love," while (until recently) Tom was only looking for love of the one-night variety.
434* The public perception of [[LondonGangster the Kray twins]] has traditionally had Ronnie, the younger twin, as pure AxCrazy psychopath, and Reggie as quieter and more AffablyEvil, even acting as something of a MoralityChain to his brother. There's not necessarily much evidence of this, but that just makes the fact that people ''want'' it to be the case an example of this trope in action.
435* Twin musicians Chuck (bass) and John (drums) Panozzo of Music/{{Styx}}. Chuck is soft-spoken and more down-to-earth, while John [[AllDrummersAreAnimals was a wild man]] and more outgoing.
436* Happens to twins in RealLife, as twins growing up together try to develop different personalities to distinguish themselves from their sibling. However this is usually subverted in identical twins -- twins that came from the same zygote, not from two different zygotes in the womb -- as they are practically genetically identical copies of each other and will share many similarities in personality and preferences even if they act differently. National Geographic has done an article on it.
