%% * ''Anime/TransformersArmada'': the Star Saber, Skyboom Shield, and Requiem Blaster.

* ''ComicBook/TheLegendOfTheChaosGod'' is a Disney multi-'verse crossover comic centering on an ancient monster kept imprisoned after it was [[SealedEvilInACan sealed into]] [[CrystalPrison a ruby crystal with a gold setting]]. As long as the crystal and setting remained seperate, the monster couldn't escape. But someone stole the two and wanted to revive it. The consciousness in the crystal influenced characters as it tried to get itself reunited with the setting.

* Each set of rings in ''Literature/TheLordOfTheRings'', except for the supreme (and evil) One Ring, which has no counterparts.

* Creator/MichaelMoorcock's ''[[Literature/TheElricSaga Elric of Melnibone]]'' stories. The twin swords Stormbringer and Mournblade, one possessed by Elric and the other by Elric's cousin (and enemy) Yyrkoon.

* Maybe parodied in ''Literature/JourneyToTheWest'': After stealing the dreaded Crinsom Gourd (capable of sucking inside and melting people called by name in front of it) and putting a fake in its place, Monkey challenges the owner Silver Horned King to a duel, claiming that he possess the "male" counterpart of his gourd. He does an identical trick later, this time claiming that he possessed the "female" counterparts of a trio of deadly bells.
* In the second ''Literature/{{Dinotopia}}'' book, 'The World Beneath', Arthur searches for the other half of an old key that opens a door in the World Beneath. Its owner, Oriana, ends up going with him on the expedition.

* ''Franchise/PowerRangers'' morphing devices.

* ''Videogame/{{Suikoden}}'':
** The Bright Shield and Dark Sword runes in ''Videogame/SuikodenII''.
** ''Videogame/SuikodenV'' has the Dawn and Twilight runes; they're opposites to each other, but not opposed, as they both work to keep the Sun rune in check.
* Seraphim, the sword of ''VideoGame/ExitFate'' protagonist Daniel Vinyard, and its counterpart Cherubim.
* The White Chronicle and the Black Chronicle in ''VideoGame/RadiantHistoria''.
* The ''Videogame/SoulSeries'' has Soul Edge and Soul Calibur which represent chaos and order (Calibur was made from a purified shard of Edge, so it's still kind of evil). Both get stronger when Soul Edge absorbs souls.
* ''Franchise/KingdomHearts'' has a million and one Keyblades, and with several Keyblade wielders, it's no surprise that this trope is pulled every so often.
** Sora and Riku: in the first game, Riku gets an [[DepartmentOfRedundancyDepartment evil keyblade of evil]] to unlock peoples' hearts rather than, more harmlessly, doors.

* ''VideoGame/FireEmblemRadiantDawn'' has the two blessed swords formerly wielded by the heroine Altina, the golden Ragnell and the silver Alondite.
* ''VisualNovel/FateStayNight'' has Archer's chinese swords, Kanshou and Bakuya, that have a yin-yang theme going on and magnetically attract each other.
* ''VideoGame/KingdomOfLoathing'' has a set of five elemental clubs for the Seal Clubber, which are smithed from a [[http://kol.coldfront.net/thekolwiki/index.php/Bad-ass_club Bad-ass club]] and an item obtained from an Infernal Seal, and a high-tier chefstaff for each element, all of which are made of a staff associated with the respective elements and elemental feathers, noodle dishes, mushroom wine and wads.

* ''VideoGame/KingdomsOfCamelot'' on Facebook has four elemental Guardians: Wood, Ore, Stone and Water, each of which raises production of that resource (water actually raises Food, there is no 'water' resource) and adds to attack or defense stats in battle. SetBonus applies here.
* ''VideoGame/DragonAgeOrigins'' had the twin rings Dusk and Dawn, while the expansion had Dumat's Spine and Dumat's Claw, a sword and a dagger created from the bones of the first Archdemon.

* ''VideoGame/{{Egoboo}}'': The Sporks of Yore. They serve as a DismantledMacGuffin, and each of them is attuned to a different virtue.
* ''VideoGame/MightAndMagic VIII'' has Elsenrail and Glomenthal. Though they have no story influence, their flavour texts describe them as linked yet opposite, with Elsenrail being the Blade of Light and Glomenthal being the Blade of Dark, and the forging of these Swords of Balance having destroyed the Forge of Chaos.

* ''Series/TheLordOfTheRingsTheRingsOfPower'': The first three Rings of Power created by Celebrimbor for the Elven kind: Vilya, Nenya, and Narya.

[[folder:Film]]

* The Atlantean Scion from the original ''VideoGame/TombRaider''. Three pieces, one for each ruler of Atlantis.

* ''Franchise/WonderWoman'': The Lasso of Truth and the Lasso of Submission. [[ComicBook/WonderGirl Cassie]]'s Lightening Lasso is made to call the other two to mind but doesn't really fit as it's designed to channel Zeus' powers through her.

* ''Franchise/FinalFantasy'': A recurring theme related to the series's themes of DarkIsNotEvil and balance between light and darkness is that the four Elemental Crystals have counterpart Dark Crystals. They pop up in ''[[Videogame/FinalFantasyI I]]'', ''[[Videogame/FinalFantasyIII III]]'', and ''[[Videogame/FinalFantasyIV I]]V''. ''V'' has no Dark Crystals, but does have a counterpart quartet of Crystals in the second world.

** ''Videogame/FinalFantasyVII'', Sephiroth seeks the Black Materia that can call Meteor. Aerith in turn has the White Materia that can call Holy, which can destroy Meteor.

One common plot element is {{the Hero}} having to acquire one of these to allow him to defend against and/or defeat the villain, who has the counterpart, making each item a NemesisWeapon to the other. It's also common to distribute them among siblings, partners or a group of TrueCompanions.

* In the 1980s version of ''WesternAnimation/{{ThunderCats|1985}}'', the Sword of Omens had an evil counterpart in the Sword of Plundarr.

* In Filmation's re-imagining of the ''Blackstar'' concept, ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'', He-Man and Skeletor each wield half of the Power Sword.

* ''VideoGame/TheLegendOfZeldaI'', the iconic Triforce began as this, Zelda having the Triforce of Wisdom and Ganon the Triforce of Power. It wasn't until the second game that the Triforce of Courage was introduced.
** In ''VideoGame/TheLegendOfZeldaSkywardSword'', the Goddess/Master Sword and the Demon King's sword, [[spoiler: Ghirahim]]. Also, among the collectibles you can find are Amber Relics (pretty much anywhere); their counterpart, the Dusk Relics, can also be found pretty much anywhere but only during the Silent Realm trials.

Sometimes you GottaCatchThemAll to enter a place or learn a special technique; compare AllYourPowersCombined and DismantledMacGuffin.

[[folder:Toys]]
* ''Toys/{{BIONICLE}}'': the Mask of Light and the Mask of Shadows. They were combined once in TheMovie.

** The relationship is inverted in the [[WesternAnimation/ThunderCats2011 reboot series]]: the Sword of Omens was created as a ''good'' counterpart to the Sword of Plundarr, forged from the metal slag that was left over after its creation.
