''[[http://www.fimfiction.net/story/101408/black-queen-red-king Black Queen, Red King]]'' is a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fan fiction story by [[http://www.fimfiction.net/user/wille179 wille179]][[note]] who is also a troper[[/note]].

''Black Queen, Red King'' stars a teenage boy named [[OrdinaryHighSchoolStudent William]] who forms a [[PsychicLink psychic connection]] with [[Characters/FriendshipIsMagicMajorVillains Queen Chrysalis]]. The story is set on a version of Earth [[TwentyMinutesIntoTheFuture set in the year 2029]] and during the middle of season two of ''My Little Pony''.

Eventually, William[[note]] who changes his name to [[MeaningfulName Alvarium Rex]][[/note]] after {{metamorphosis}} into a [[HiveQueen royal]] [[VoluntaryShapeShifting changeling]] capable of [[{{Teleportation}} transporting matter]] and opening [[ThinkingUpPortals portals]] to Chrysalis's universe.

The thing is, he's not the only human to start pairing up with creatures in the other world, and not every human is as interested as he is at [[{{Masquerade}} upholding the masquerade.]] And then there's [[OmnicidalManiac Oblivion...]][[note]] who is more of a multiverse-scale SpacetimeEater.[[/note]]

''Black Queen, Red King'' has a companion story named ''[[http://www.fimfiction.net/story/177244/gatekeeper-prince-of-darkness Gatekeeper: Prince of Darkness]]'' written by [[http://www.fimfiction.net/user/InfiniteBrony InfiniteBrony.]] It follows the adventures of [[TheDon Victor DiVinci]], who may or may not be [[PsychicPowers Clairvoyant]], and his partner, [[TheEvilPrince King]] [[LivingShadow Sombra]].

Several other authors are writing additional side stories featuring other Characters within the same [[SharedUniverse 'verse]].

Has since been unofficially canceled as {{Tropers/wille179}} has left the fandom.
----
!! "Black Queen, Red King" provides examples of:
* AccidentalMurder: [[spoiler:Catherine]] is killed when [[spoiler:Gilda]] attempts to free her from her cocoon. She drops twenty feet and breaks her neck. [[spoiler:Gilda [[HoistByHisOwnPetard dies a minute later due to the connection of their souls]].]]
* AmnesiaDanger: Two examples:
** Taruke uses a spell to prevent memories from forming, Trapping Victor for a time because he cannot remember his detectors going off.
** [[SpacetimeEater Oblivion]] can erase all evidence of its existence, including memory. It's also the BigBad.
* AntiMagic: Catherine and Co. get their hands on a set of Anti-Magic rings. The problem for Catherine is that they nullify the magic in her wings, rendering her flightless.
* ArtifactOfAttraction: Anything that has the Want-It, Need-It spell cast on it. Inverted: the Notice-Me-Not spell.
* {{Autocannibalism}}: Rex eats his own arm after it gets shot off in order to recover the [[HealingFactor nutrients he needs to heal]].
* BoomHeadshot: Rex was shot in the head at close range.
* BrainwashingForTheGreaterGood: Rex uses cognitive dissonance and positive reinforcement to curb Slagteri's murderous tendancies.
* BrokenMasquerade: Catherine discovers early on that William is actually a changeling.
** Later, she creates a whole anti-changeling movement dedicated to ending the {{Masquerade}}.
* ConspiracyTheorist: Catherine and the anti-changeling movement all qualify as this.
* CurseThatCures: Implied that becoming a changeling helped Slagteri quit using heroin.
* DeadMansSwitch: The anti-changeling movement has ''twelve of them.'' One eventually does go off.
%%* DeathByFallingOver: See AccidentalMurder above.
* DemonicPossession: At one point, Rex pretends to be the devil, kidnaps a serial killer from a prison, rips out the man's soul, and then Rex animates the body with a fragment of his own soul to create Ψ.
* EatTheEvidence: Changelings eat the bodies of their [[DisposingOfABody own dead and those of the humans they kill]] in order to uphold the {{Masquerade}}.
* EldritchAbomination: There are at least six of them named, each vaguely described at best. They are [[spoiler: Rex and Chrysalis's souls]], [[spoiler: the mouth of Death/Chaos]], [[spoiler:the darkness]], [[spoiler:Scythirraax]], and[[spoiler: [[SpacetimeEater Oblivion]]]].
* EmotionEater: The changelings are this. They can feed on ambient positive emotions, actively drain someone nearby who feels emotions towards them, or rip the emotions from their prey by biting the victim[[note]] which causes the victim to rapidly age[[/note]].
* GlamourFailure: Cause a changeling pain, and it (partially) reverts to normal. Also, Rex's eyes tend to revert temporarily when he is overcome with lust or anger.
* {{Greed}}: Rex, who spends time as a bank robber, and Taruke, the hive's accountant, the most economically minded of the hive.
* HeKnowsTooMuch: Any human who discovers the changelings is considered this by the changelings.
* {{Hermaphrodite}}: Changelings. Rex and Chrysalis have both impregnated themselves at some point in time.
* HiveMind: Each changeling hive has its own mental network. It acts like a PsychicLink most of the time, but it can be turned up all the way to full unity and control.
* HiveQueen: William and Chrysalis both qualify. They each have their own hive.
* HorrorHunger: Downplayed due to a lack of emphasis on the ''horror'' part. The list of horrifying things Rex has eaten (and enjoyed) include (true) love/lust/happiness[[note]] not eating emotions causes heart failure in changelings[[/note]], human flesh, other changelings (his own subjects, though this was in a funeral for their murders; the changelings eat their own dead) and human souls. However, he is not so much upset about his appetite as what his (human) daughter would think of him if she knew.
* IHaveManyNames: Rex has ''sixty'' different false [=IDs=], several of which are opposite genders.
* ImAHumanitarian: The changelings eat their own dead. It is a decision based on practicality, as it [[EatTheEvidence eliminates the risk of the body being found later]].
ImHavingSoulPains: John Smith suffers from this right before his soul is [[spoiler: crushed to death and consumed by Rex.]]
* JoinOrDie: Played with: The anti-changeling movement is told that they can join... or leave the room completely unharmed. What they don't know is that the latter option involves cocooning them and using them as food.
** Averted the next chapter: all of the cocooned humans are converted to stop a series of [[DeadMansSwitch dead man's switches]] from going off. It's not done soon enough.
* KilledToUpholdTheMasquerade: The Silencers tend to do this from time to time.
* LaserGuidedAmnesia: The hive is searching for a way to do this to humans in order to keep their existence a secret, but has yet to succeed.
* LotusEaterMachine: Changeling venom paralyses its victims and forces them to hallucinate visions of the people they love, often erotic visions. It is the emotional equivalent of digestive enzymes.
%%* {{Lust}}: Changelings in general are big fans, since this is a quick substitute for love.
* {{Magitek}}: One of the goals of Research & Development. [[InstantAIJustAddWater Change.lng is a sentient, animated computer program]], while Rex creates a golem out of a robot and the soul of a serial killer[[note]] He destroys it a minute later. It was just a proof-of-concept[[/note]].
* {{Masquerade}}: Ginny Skinner and the Silencers work for the hive to uphold the masquerade.
* MeaningfulName: Invoked: the changelings on Earth choose their own names.
** Lampshaded by Klika in this quote to Taruke: "We all name ourselves; Protector[[note]] Taruke, whom she's speaking to[[/note]], Slaughterhouse, Daughter,[[note]] the meaning of Klika's name in the changeling language[[/note]] Stalker – of course it’s fitting."
** Slagteri: As a definite case of NamesToRunAwayFromReallyFast, his name means Slaughterhouse.
* MindRape: Rex does this to his subjects on a couple of occasions, sometimes on accident. There was even a case where a changeling, having had her personality altered, is DrivenToSuicide.
* MushroomSamba: Oddly, Candy Hearts do this to changelings as a combination of Weed and LSD. It also makes them continuously excrete binding gel and temporarily restores their ability to taste normal food[[note]] much to their delight[[/note]].
* MisterSeahorse: Since changelings are biologically capable of holding both reproductive roles, any changelings that identify as male qualify[[note]]the main character included[[/note]].
* MonsterProgenitor: Rex and Chrysalis both serve as this for their respective hives.
* OneGenderRace: Changelings are this, which aids in their ability to assume the forms of both human genders. Changelings can both sexually[[note]]Each partner takes the role of either male or female[[/note]] or asexually[[note]] Only the king/queen can do this[[/note]]. Rex is both the mother and father of Klika.
* OneLetterName: Ψ, the artificial drone changeling. Bonus points for being a Greek letter.
* OrdinaryHighSchoolStudent: William, Nick, and Catherine each start out in high school. They graduate in a few chapters.
* OurSoulsAreDifferent: Rex gains the ability to see souls. He describes them as brilliant, flaming figures that glow an impossible color. His own soul [[spoiler: is described as a horrifying monstrosity that damages the eyes of those who look at it.]]
* PaintingTheMedium: While Rex telepathically thinks to Chrysalis, it's in orange. When she replies, it's in green.
** Discord (rather, his counterpart [[Creator/JohnDeLancie John]] [[Series/StarTrekTheNextGeneration Q.]] [[SdrawkcabName Drocsid]]) thinks, writes[[note]] even his letter, written in green crayon, turns to blue ink. This was [[LampshadeHanging lampshaded]] by his psychologist[[/note]], and speaks in blue.
** Also, certain words that describe [[spoiler: Rex and Chrysalis's souls]] have Zalgo text, like this: t҉̻̙ḛ͈̩̫͚n̠̭͍̗̫d̤̬͍͇̲͝ͅr̘̯͠i͝ļs̞̤̜͓.
* PhysicalGod: Celestia, Luna, and Cadance qualify. It is implied that Selene is one, too, though it is never explicitly stated.
* PortalCut: The characters have often used teleportation to cut things, including security cameras, a giant cocoon, and a man's hand.
* {{Pride}}: Taruke is extreamly prideful of his contributions to the hive and that his mind was warped by Rex[[note]] he considers it a blessing[[/note]]
* ResurrectiveImmortality: Rex, Chrysalis, and all [[PhysicalGod physical gods]]. However, the mechanism behind the resurrection is different for each. Rex and Chrysalis have to climb their way back from the afterlive, while the [[PhysicalGod physical gods]] just don't stay dead.
* ShapeshifterBaggage: The changelings can shrink down to the size of flies or grow to the size of a large man. WordOfGod handwaves this by saying that the false bodies are magical constructs with simulated mass.
* SharedUniverse: ''[[http://www.fimfiction.net/story/177244/gatekeeper-prince-of-darkness Gatekeeper: Prince of Darkness]]'' is set in the same universe. Many other authors are looking at joining.
%%* SevenDeadlySins: Many characters exhibit some of the sins.
* SoulPower: Rex and Sally-Anne, to a lesser extent, have this power.
* TailorMadePrison: Two examples: The prison for Discord is [[DiscussedTrope talked about]] while ''inside'' a temporary, custom prison for Victor. The former was designed to launch Discord elsewhere in the multiverse, while the latter simultaneously held mind and body prisoner.
* {{Teleportation}}: With a snap of their fingers, any Gatekeeper can teleport matter to their counterpart.
* TheMenInBlack: The Silencer Division were established explicitly for this purpose.
* ThinkingUpPortals: This is one of the default power of the Gatekeepers.
* ToServeMan: Many of the changelings, hatched and [[ImAHumanitarian ex-human]] alike have eaten human meat.
* TransferableMemory: Changelings can easily upload their memories to the HiveMind, and all memories there are known by everyone in the hive.
* TranshumanTreachery: Most converted changelings are this way, though Slagteri and Taruke take it up to eleven. However, the latter case suffered from MindRape, which made him that way.
* TwentyMinutesIntoTheFuture: The story is set in the year 2029.
* VerbalTic: Selene has one, see?
* VillainousGlutton: Rex. This overlaps with lust due to the way [[EmotionEater changelings feed]].
* VoluntaryShapeShifting: The changelings. This is the primary power of their species.
* WarmBloodbagsAreEverywhere: Rex comments about ''not telling Selene about this'' in the narration. He wants both human emotions and human/changeling flesh.
* WingedHumanoid: Catherine and Selene, who both grew wings. Gilda, a griffin that turned humanoid, also applies.
* WordOfGod: Loads and loads. The author gives commentary at the end of almost every single chapter.
* YouCannotGraspTheTrueForm: [[spoiler: Rex's soul]] damages Sally-Anne's eyes and visual cortex when she sees it.
* YourHeadAsplode: Rex was shot in the head at close range.
* YourSoulIsMine: Rex says the name of the trope verbatim to John, then proceeds to rip his soul out, play with it, and then accidentally ''swallow'' the man's soul.
