History Main / PolarOppositeTwins

* The main characters of ''Series/ComplicesAlRescate'' are the SeparatedAtBirth twins Silvana and Mariana. Silvana is the vain, snobby and bratty twin that was raised by her rich foster parents while Mariana is the humble, sweet and cheerful twin that was raised by her biological family in a very small town and is much poorer.

[[caption-width-right:250:And this is ''before'' they were redesigned.]]

* ''WesternAnimation/TheLoudHouse'' features Lana, a caring AnimalLover who enjoys FilthyFun, and Lola, a bratty pageant queen who wants to rule the world.

* ''WesternAnimation/TheLoudHouse'' has identical twin sisters [[TomboyAndGirlyGirl Lana and Lola]]. Lana's masculine, tomboyish and loves getting dirty, whereas Lola [[PrincessPhase dresses like a princess]], regularly competes in beauty pageants, and is far more conceited than her twin.

* The elves of ''TabletopGame/{{Warhammer}}'' fantasy really seem to be prone to this trope.
** 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]].
** 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.
** 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. They ride a dragon.
* ''TabletopGame/{{Ravenloft}}'s'' 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.]]
* A number of the gods in pre-Fourth Edition ''TabletopGame/ForgottenRealms'' were opposed siblings, though they usually looked noticeably different--Shar and Selune (the moon and the dark), Tymora and Beshaba (good and bad luck), Vhaeraun and Eilistraee (drow thieves, often male, and redeemed drow, often female).

-->"How different can you really be from your ''twin sister''?"

* ''Film/UnderworldEvolution'': 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]].

* ''WesternAnimation/YinYangYo'' has [[BadassBookworm smart]] NeatFreak Yin and her [[BookDumb less intelligent]] [[BloodKnight violence loving]] brother, Yang.

* ''Manga/BlueExorcist'' is essentially about a pair of these, as both Okumura brothers are very different: [[BigLittleBrother Yukio]] is a [[TheStoic stoic]] BadassBookworm TeenGenius 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. 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}}.

* ''[[https://www.fanfiction.net/s/3481778/1/The-Hero-Strikes-Back The Hero Strikes Back]]'' has [[Film/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.

* ''LightNovel/IveBeenKillingSlimesFor300YearsAndMaxedOutMyLevel'' has the slime spirit twins, Shalsha and Falfa. The former is cold, bookish, and reserved, and the latter is warm, sporty, and outgoing.

* ''{{LightNovel/Durarara}}'': Mairu and Kururi Orihara actually [[InvokedTrope invoked]] 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. Even weirder is the fact that they don't consider themselves [[TheDividual separate people]].
