[[caption-width-right:293:Pictured: The general Drow (Dark Elf) greeting reserved for Surface Elves in ''The Forgotten Realms''.]]
Two races, one AlwaysLawfulGood and one AlwaysChaoticEvil, which are specifically counterparts of each other. Essentially an EvilCounterpart on a species wide scale, and related to CainAndAbel and other sibling rivalry tropes.

While ElvesVsDwarves is about HarmonyVersusDiscipline, this is about good and evil, at least from the elves' point of view. Often subverted by a DefectorFromDecadence or deconstructed when it's discovered that the 'good' race is not so harmless, or the evil one has a case of MySpeciesDothProtestTooMuch (or is [[DarkIsNotEvil merely dark and not evil]]).

!!Examples

[[folder: Comic Books ]]

* Green Martians like the MartianManhunter J'onn J'onnz are wise, peaceful, and obscenely powerful (with one exception: OmnicidalManiac and EvilCripple Malefic). White Martians have all the powers of their green cousins, but are monstrously evil (also with, to date, a single exception). No, the respective exceptions are not in any meaningful way counterparts.
* Daxamites are descended from [[Franchise/{{Superman}} Kryptonian]] colonists, and gain the same powers at the same levels when exposed to the light of a yellow sun (though they're vulnerable to lead instead of [[KryptoniteFactor kryptonite]]). Unlike Superman, Supergirl, Power Girl and other Kryptonian heroes, though, Daxamites are rabidly xenophobic, to the point of murdering an alien who accidentally crashed on their planet. When a Korugarian Green Lantern helped liberate them from an alien conqueror, they merely demanded she leave the planet rather than killing her, as a show of gratitude. This really bites them in ass when the Sinestro Corps invaded.

[[folder: Film ]]

* The urRu and the Skeksis of ''Film/TheDarkCrystal.'' They're actually the good and evil halves of the same species.
* ''Film/TheSmurfs2'' has [[BigBad Gargamel]] creating the Naughties, who are two ChaoticEvil grey-skinned Smurf-like beings.

[[folder: Literature ]]

* In H.G. Wells' ''TheTimeMachine'', the pilot of a prototype time machine discovers himself in AD 802,701, where humans have apparently evolved into two species, the Eloi and the Morlocks. The Eloi are childlike, harmless people preyed upon by the Morlocks.
** In the original novel this was depicted as necessary symbiosis, since the Eloi can't live without the Morlocks running the machinery that keeps their home so idyllic. It's a major TakeThat at the late Victorian society where few aristocrats could enjoy luxuries of "natural" lifestyle at the cost of thousands of workers living in squalid, artifical conditions for all their lives. Today, similar comparisons could be drawn between the developed countries and the Third World.
** The Eloi incidentally aren't "good", but useless and childish, beautiful but meaningless. This has been heavily {{flanderiz|ation}}ed in the subsequent adaptions that omit the DownerEnding.
* In ''Literature/TheLordOfTheRings'', because '[[CreativeSterility the Enemy cannot make, he can only mock]]', some villainous races are literally bad counterfeits of good ones, such as Orcs of Elves and Trolls of Ents. There does not appear to be a set for Dwarves and Men, presumably because the Enemy was able to corrupt some of them directly, though some characters speculate that Saruman's 'goblin-men' Uruk-hai represent a blending of the races of Orcs and Men.
* Not a race but rather a religion, the ''Literature/HonorHarrington'' series has the two worlds which follow "The Church of Humanity Unchained:" Grayson, which is mostly just "heavily conservative", and Masada, which is violently misogynistic. It was an ugly schism.
* In the Literature/FirebirdTrilogy, the Shuhr are originally presented as the evil counterpart to the Sentinels. Brennen Caldwell, a high level Sentinel, even remarks once that the Shuhr provide a prime example of what the Sentinels would be like if not for the Sentinel's strictly enforced self-imposed moral and ethical codes. However, the trope is played with in the earlier books, as we see both {{Face Heel Turn}}s and a HeelFaceTurn, and ultimately subverted in ''Wind and Shadow'', where it is shown that only the upper level of the Shuhr were despicable, with the rest of the people being normal.
* ''Literature/MortalInstruments'':[[spoiler: The Dark Shadowhunters that Jonathan Morgenstern creates using the Infernal Cup and Lilith's blood. They are stronger and faster than regular Shadowhunters, but cannot use their Runes or angelically aligned weapons. Whether they will develop demonic equivalents remains to be seen]].

[[folder: Live Action TV ]]

* The ''Series/{{Star Trek|The Original Series}}'' episode [[http://en.wikipedia.org/wiki/Let_That_Be_Your_Last_Battlefield "Let That Be Your Last Battlefield"]] is an extreme case where Bele acts as if Lokai is a member of an AlwaysChaoticEvil race, despite it clearly being a case of GreyAndGrayMorality from the crew's point of view.
** Also in ''Franchise/StarTrek'', the Romulans to the Vulcans.
** In the Original Series, the Klingons to Humans.
** Within TheFederation's EvilCounterpart, [[TheEmpire The Dominion]].
*** The Changelings to The Prophets
*** The Vorta to Bajorans
*** The Jem'hadar to the Klingons.
*** The Dominion arc also introduced two profit driven races, the Dosi, evil counterparts to the ferengi, and the Karemma, who are good counterparts!
** Not forgetting [[OurDemonsAreDifferent the Pah-wraiths]] to [[OurAngelsAreDifferent the Prophets]].
* ''Series/StargateSG1'' had the Goa'uld vs. Tok'ra and the Ori vs. Ancients. In both cases the good race operated behind the scenes (the Tok'ra worked as spies and saboteurs since they lacked the numbers and the means to replenish them, and only a couple Ancients even tried to circumvent their self-imposed non-interference laws) while the bad race went around shouting "Worship me!"

[[folder: Religion ]]

* [[OurAngelsAreDifferent Angels]] and [[FallenAngel fallen angels]][[OurDemonsAreDifferent /demons]] in a lot of {{works}}, though in the Literature/TheBible they're the same species, just on different sides.
* {{Subverted}} in {{Islam}}. The Devil (called 'Iblis') and humankind are fated to be enemies, but the descendants of the Devil --the Djinns-- have free will just like humans, they can choose to be good or to be evil, thus they aren't human's Evil Counterpart Race. Of note is that they aren't counterpart to angels either, because Iblis was never an angel to begin with.

[[folder: Tabletop Games ]]

* ''TabletopGame/DungeonsAndDragons'' has a habit of doing this for ''everyone'', creating evil (and occasionally good) counterpart races for just about everything:
** Elves vs. Drow.
** Dwarves vs. Derro and Duergar.
** Aasimar and Tieflings from ''{{Planescape}}'' onwards.
** The Githzerai and Githyanki - though that's more like "paranoid neutral isolationists" and their evil counterpart.
** [[GoodColoursEvilColours Chromatic (evil) and metallic (good)]] dragons in many D&D settings -- especially ''TabletopGame/{{Dragonlance}}'', where the chromatic dragons were corrupted versions of the original good dragons.
** Subverted with the Svirfneblin, the Deep Gnomes from the Underdark, the home of the drow. [[DarkIsNotEvil They aren't evil]] (generally neutral, actually), but certainly can be considered 'dark gnomes'.
*** But played straight with the Gnomes and Kobolds due to the fact that their gods hate each other.
** "The Book of Vile Darkness" gives us Jerren for Halflings and Vashar, who are a race of purely evil humans.
* ''WarhammerFantasy'' has both High Elves vs. Dark Elves (with both being highly magical naval oriented empires who hate each others guts...) Oh, and incidentally humans usually can't tell them apart... And the dwarfish counterpart Chaos Dwarves (who are even more greedy than the regular variant) arguably the Vampire Counts also serve as a twisted reflection of Empire society, and the Beastmen serve a similar role for the Wood Elves.
** The bit about humans' difficulty in telling High and Dark Elves apart is odd, because their visual designs pretty much scream good guys and bad guys respectively.
** In ''Elfslayer'', a particularly naive High Elf couldn't tell a Dark Elf was a Dark Elf (and was severely reprimanded by his bodyguard for that). Then again, Dark Elf cultists frequently infiltrate High Elf society, so it's not just naive High Elves who can't tell them apart.
* Dark Eldar in ''TabletopGame/{{Warhammer 40000}}''. [[BlackAndGreyMorality Although the Craftworld Eldar aren't exactly nice guys either]].
** The Eldar and the Necrons.

[[/folder]]

[[folder: Toys ]]

* Franchise/{{Lego}}'s ''WesternAnimation/{{Mixels}}'' has the titular characters opposed by the Nixels, who represent conformity juxtaposed to the Mixels representing creativity. This is apparent in their black and white blocky appearance and their base looking completely blank inside.

[[/folder]]

[[folder: Video Games ]]

* In the ''VideoGame/{{Warcraft}}'' games, night elves are not especially fond of high elves, and are downright hostile to blood elves. In addition, gnomes vs. goblins, and humans vs. orcs. The gnomes vs. goblins is more of a rivalry than outright hostility, though.
** There are also specific subraces like the Dark Iron dwarves (generally same look but black skin) or the several kinds of trolls opposing the Darkspear tribe that belongs to the Horde. And in Northrend there are several races heavily implied or outright stated to be the original of the player races, which developed on their own over time.
** Way back in ''Warcraft II'' trolls served as the Evil Counterpart Race for the elves (before the eigh elf/blood elf split and before we knew of the night elves), both races providing the main ranged unit and light naval craft for their respective factions.
* The ''VideoGame/{{Warlords}}'' games, as well as having High Elves and Dark Elves, has Dwarves and Dark Dwarves, the former being the typical ale-swilling axe-bearers, the latter being industrial {{Mad Scientist}}s.
* In ''Franchise/DragonAge'', The Darkspawn are created when [[spoiler:a female of a race -Human, Elf, Qunari or Dwarf- is captured and turned into a [[FateWorseThanDeath Broodmother]] and spawns them.]] Each race has a Darkspawn equivalent that is [[spoiler:born of the Broodmother]] of that race- Human [[spoiler:Broodmothers]] produce Hurlocks, Dwarves produce Genlocks, Elves produce Shrieks, and Qunari produce Ogres. Dark''spawn'', indeed.
* A lot of Franchise/{{Digimon}} species are Evil Counterparts to other species:
** Devimon to Angemon.
** Deathmon and Demon to Seraphimon
** Lilithmon to Ophanimon
** Kuwagamon to Kabuterimon
** Tsukaimon to Patamon
** And, of course, the innumerable examples of cases where the evil counterpart's name is the good version's name plus the word 'black' (and coloring alterations to match), such as [=BlackAgumon=], [=BlackTailmon=], [=BlackToyAgumon=], [=BlackWarGreymon=], etc. Justified in that they are intended according to the fluff to literally have originally been of the resepective good race, but were transformed by computer viruses.
* Goombas to Toads in ''Franchise/SuperMarioBros''

[[folder: Webcomics ]]

* Played with in ''Webcomic/{{Drowtales}}'', as explained in the no-longer-canon guide [[http://www.drowtales.com/worldsettingarchive.php?id=15 here]].

[[folder: Western Animation ]]

* Fairies versus anti-fairies and pixies in ''WesternAnimation/TheFairlyOddparents''.
