{{Fandom Specific Plot}}s amongst ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction writers.
----

* ''The'' standard plot for getting the ponies themselves into [[AlternateUniverseFic another]] [[CrossOver universe]] is famously "Twilight Sparkle tests out a new teleport spell, and it goes wrong". It's gotten to where Blog/EquestriaDaily [[LampshadeHanging explicitly points it out]] when a fic ''doesn't'' do this before they started banning such stories.
** It's not just "teleport turns into dimensional travel"; when Twilight tries out ''any'' new spell in fanfic, [[{{Flanderization}} things will go south]]. One fanfic involving Twilight visiting a darker parallel universe had Equestria Daily note that the universe's existence isn't her fault: "Is that even ''allowed''?"
* Because of copious use of SchizoTech and other arguably non-pony-friendly tools and equipment, it is a common FandomSpecificPlot to depict this show as taking place after HumanitysWake.
* Before Season 2, stories about the [[FanNickname mane six]] having to face the "Elements of Discord/Disharmony/Chaos", {{Evil Counterpart}}s to their Elements of Harmony, were quite common.
* ''After'' Season 2 and [[IKnewIt the reveal of]] Discord, [[GodOfEvil spirit of chaos and disharmony]], stories abounded with Discord escaping from [[SealedEvilInACan his can]] again, either to continue to wreak havoc... or somehow falling into DefeatMeansFriendship, despite him being one of the few purely evil characters in the entire series. The second of these became HilariousInHindsight given the premise of the Season 3 episode, "Keep Calm and Flutter On".
** Prior to his reformation, Discord was a prime choice for an UltimateEvil-type entity when one was needed to act as the BigBad or BiggerBad of a story, due to his nature as a god of chaos and disharmony and even now being one of the most powerful characters in the series short of Celestia and Luna.
*** A combination of the below and above, was an EnemyMine type where Discord would be forced to join with the Mane Six. Bonus points if it turned out the thing created Discord, or at least Discord knew what it was.
** Alternatively, an even ''worse'' evil shows up for the mane six to thwart, most commonly yet another SealedEvilInACan that Celestia and Luna dealt with millennia ago. Though considering this is how Seasons 1, 2, 3, ''and'' 4 began, it might just qualify as standard series narrative at this point
*** Lampshaded by Pinkie Pie in [[http://www.fimfiction.net/story/73019/as-twilight-fades at least one fanfic]], asking after yet another threat from a thousand years ago reared its head, "Was that just a really bad year for you?" Celestia noted that the actual reason for this is rounding.
* CrossOver fics dealing with other characters getting transported to Equestria, almost always getting inexplicably "ponified" in the process. ''Series/DoctorWho'' is the most common victim of this, thanks to a background character who looks like a pony version of the Tenth Doctor known as Doctor Whooves.
* And of course [[AuthorAvatar humans in Equestria stories]], most of which are in the form of [[TrappedInTVLand humans from the real world being sucked into the show's universe]]. [[RefugeeFromTVLand The inverse]] is also just as prominent.
** Whatever the case, [[IntriguedByHumanity Lyra Heartstrings]] usually gets involved, at least as a cameo, or in a more or less prominent role.
** Said inverse was eventually made (partly-)canon with the ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'' movie, wherein Twilight Sparkle gets transported to the human world.
** FirstContact type "Human in Equestria" stories are also fairly popular. Usually, the humans are space travelers, but [[WesternAnimation/MyLittlePonyTVSpecials Megan]] has frequent appearances as well.
* It's popular to pit the gang from ''Friendship is Magic'' against updated versions of G1 villains, such as Tirek from [[WesternAnimation/MyLittlePonyTVSpecials "Rescue at Midnight Castle"]], and the Smooze from [[WesternAnimation/MyLittlePonyTheMovie the movie]].
** It's also Generally accepted that if G1 is the past of FIM in a fanfic, 9/10 times, Megan has a Religion in Equestria dedicated to her.
** It's also become fairly popular to depict, or at least reference, previous generations of ''Franchise/MyLittlePony'' as actual historical events in Equestria. Sometimes this even leads to crossovers due to time-travel or other such plot points. G1 is the most popular, but there is some G3 equivalent material out there.
** Inverted with a series of epic fanfictions known as the ''FanFic/TwilightThenTwilightNowUniverse'', aka "The Firehooves Cycle", in which a (DarkerAndEdgier) version of G1 is actually portrayed as a post-Gotterdammerung future of G4.
** This particular FandomSpecificPlot is likely to receive a huge boost, since the ending of season 4 involves a confrontation with an actual G4 rendition of Tirek, the very first G1 villain, and also namedrops Scorpan, the original Tirak's [[TheDragon lieutenant]][[note]]rendered here as his brother and equal, who pulled a HeelFaceTurn and allied with the ponies to imprison Tirek, then returned to their kingdom[[/note]].
* [[BigGood Princess]] [[ReasonableAuthorityFigure Celestia]] [[RonTheDeathEater turning out to be a horrible tyrant]], or Equestria being a CrapsaccharineWorld. Often this will involve the characters being unaware of this, and scolded by some OC (or [[DarkIsNotEvil Princess Luna]]) for [[SillyRabbitIdealismIsForKids how naive they were]].
** Or, before the events of the story, Celestia turning evil and being [[{{Irony}} sealed into the sun]].
** Corollary: Luna (or even Nightmare Moon) taking over where Celestia was de-throned.
* Rainbow Dash having an accident and, irreparably or not, injuring her wings, requiring another character to care for her (may or may not involve shipping). At one point these were ''so'' ubiquitous that Equestria Daily outright ''banned'' them. Then there was the ''actual episode'' where Rainbow broke her wing and was confined to a bed... [[MadeOfIron for three days]], [[RealityEnsues in a hospital]].
* Fluttershy [[HurtComfortFic nursing a hurt character back to health]] (which has some basis, given that she's the Element of Kindness), often overlapping with the above.
* Trixie is a common target for {{Hurt Comfort Fic}}s, and multiple fics exist for her being taken in by (and often [[FoeYay shipped with]]) every single member of the mane cast, but especially Twilight.
* Unless it's a story where EveryoneIsGay, Rainbow Dash is the go-to choice for a lesbian or bi-curious character. Some fics in turn play with this by having her defy this stereotype and be offended by other characters making this presumption of her.
* "Character X becomes an alicorn" has always been a popular plot, as it allowed exploration of what it ''meant'' to be an alicorn, having to deal with power and immortality, and what the Canterlot royalty was like. While all of the mane six have undergone it at some point, Twilight was by far the most common. [[spoiler:And then [[IKnewIt it actually happened]].]]
** A popular theme in these has Twilight Sparkle (and possibly the other members of the mane six as well) turning into alicorns and taking over the rule of Equestria from Celestia and Luna, who have [[WhoWantsToLiveForever grown tired of immortality]].
* It used to be common for [[MemeticBystander Derpy]] to be TheWoobie, having a speaking disorder that typically made her speak gibberish and being TheKlutz, which caused her to be ostracized by other ponies. This plot has since faded out, with more fans (and the show itself) preferring Derpy as just being a klutz with a lazy eye instead of disabled, and the only remainder of it is Derpy calling Dinky "muffin".
** In Derpy fics where she's the mother of Dinky, it'll often center around the hardships of being a single mother, and Dinky would either be embarrassed of her mom but learn to accept her by the end, or would be the helpful daughter.
* Many a [[FanPreferredCouple Bonbon and Lyra]] fic are about Lyra being unable to get a job, as she's a musician in {{Fanon}}. [=LyraBon=] itself is a very common ship, and the pair is frequently presented as together or married even in random stories that aren't even about them.
* "Luna reintegrates into Equestrian society" stories became endemic in the fandom almost since day one, even after the actual episode which featured it, with ''FanFic/{{Progress}}'' only being the most well known. Almost all contain some form of TheAtoner mixed with {{Adorkable}}, NoSocialSkills and FishOutOfTemporalWater, and most draw some sort of parallel to Twilight's situation, if not outright having Twilight help her adjust. "Luna Eclipsed" [[IKnewIt confirmed all of these]] and further strengthened their prevalence, although later ones drop the fan-made ShrinkingViolet portrayal and adopt the official LargeHam portrayal.
* Any fanfic centered on Scootaloo is usually gonna make her [[TheWoobie an object of pity]]; it'll either be about her inability to fly or her lack of any known family. She often ends up being comforted or adopted by Rainbow Dash as a result. Her inability to fly [[IKnewIt has become canon]], to an extent, as has Rainbow Dash taking her under her wing and acting as a big sister of sorts.
** Due to the lack of visible family, "Scootaloo is discovered to be orphaned/abused/etc. and gets adopted" is practically a genre unto itself by now. Rainbow Dash is popular of course, but there are adoption stories with each of the main six, pairings among the main six, Ms. Cheerilee (it helps that in G3, Scootaloo is Cheerilee's little sister and their personalities don't change overly much for FIM) Lyra and Bon Bon, OriginalCharacters, ''fellow classmates'' of hers who are aged up for the story, Celestia, Luna, and even '''Discord.'''
* There's a surprisingly large number of fanfics about the background ponies Vinyl Scratch and Octavia--who, being a modern techno DJ and classical musician respectively--somehow have to work together, whether they go to the same university, get assigned the same radio show, or become roommates. HilarityEnsues. {{Shipping}} also frequently ensues.
* {{Alternate Universe}}s where the Elements of Harmony are assigned to different bearers. This may entail switching them around between the Mane Six, with different aspects of their personality coming to the fore (or else having different personalities ''entirely''), or having other ponies answer the call in this 'verse. Partial replacements or combinations of the above are also possible. Yet another Fandom Specific Plot that became canon (although it was a result of a magical mishap which nearly destroyed the characters' livelihoods).
* "Character X was a changeling all along" fics exploded in popularity after the changelings were introduced, though their ubiquity made them something of DeadHorseTrope before long.
** While we're talking about Changelings: there's a good number of fics revolving around a Changeling turning up in Ponyville sometime after the Royal Wedding...and one can safely bet that Fluttershy will be the first to find said Changeling.
** One fiction parodies this concept in general (though it was written as a parody of one specific fic), by making ''everypony'' a changeling (except Celestia). A three-way changeling civil war ensues.
** Speaking of ponies being Changelings, there are also a number of fics that seek to exploit the sheer ParanoiaFuel that Changelings represent, either by having them attempt to reinvade, or retconning the original invasion. But instead of the ZergRush used by the Changelings in the actual show, they make full use of their shapeshifter abilities to selectively replace ponies (including major characters), planting deep-cover agents in Equestrian society and bring about its downfall through the use of full-on infiltration and spies.
** Related to the above, some fics portray Shining Armor as a ShellShockedVeteran haunted by how he almost lost his wife and married a Changeling. Considering there's no telling just how long Chrysalis impersonated Cadance before she was discovered, some authors go for [[RapeAsDrama the most extreme interpretation]] of the FridgeHorror this invites.
** There are countless fanfics where Changelings are made out to be the [[DracoInLeatherPants noble, majestic master race]], and more often than not victims of an [[RonTheDeathEater increasingly demonized, hate-filled, fascist and Balkan-esque genocidal Equestria]].
* Trixie becoming a laughingstock and forced into destitution following the events of "Boast Busters" and seeking revenge on Twilight. Bonus points since [[IKnewIt this plot became canon]] in the episode "Magic Duel".
** Trixie being considered for Luna's apprentice. This in turn produced fics in which Trixie became the leader of a rival mane six.
* A common subject is the possibility of a Griffon kingdom/empire that rivals Equestria in power, and what the relations between ponies and griffons are like.
* "Spike gets turned into a pony" (often a pegasus, for some reason) is also pretty common, either [[BalefulPolymorph accidentally]] or deliberately in order to impress Rarity. Presumably because 1: It makes {{Shipping}} easier and 2: It's a good setup for a BeYourself Aesop that wouldn't be out of place in the actual show.
* Having crossover fanfiction wouldn't usually be considered a Fandom Specific Plot, but the ''MLP'' fandom has a disproportionate amount of them compared to most for some reason. It may have to do with one of the [[Fanfic/FalloutEquestria fandom's most popular fanfictions]] also being a crossover.
** It's very common for Equestria to serve as a sort of afterlife, with a character finding themselves in Equestria after they died in their original story.
** In particular, ''Videogame/{{Portal}}'' and ''VideoGame/TeamFortress2'' crossovers are ''extremely'' common, largely because Valve's games really helped spread the fandom in the early days.
*** Or Wheatley and the Space Sphere meet Luna out in space.
** So are ''Series/DoctorWho'' crossovers, simply by the deal of having the TARDIS land in Equestria (which, granted, is also a Fandom Specific Plot amongst ''DW'' fanfics for crossovers). Also, the Doctor almost always becomes his pony self, if he isn't already, and either Twilight or Derpy are his companions.
** Also, because of the ease with which a crossover plot can be written this way, many, many crossovers involve some spacefaring civilization making planetfall on Equestria, leading to a FirstContact type of situation.
* Twilight Sparkle grows old. This is a common topic as both her mentor and her little brother/assistant can [[WeAreAsMayflies expect to outlive her by centuries]].
** Now that Twilight is an alicorn, the tables have been turned, leading to Twilight to outlive her friends, and sometimes even Spike, Luna, and Celestia.
** It isn't uncommon to have stories of the other members of the mane cast getting together in their middle/old age and discuss just how much things have changed over the years and what sorts of issues they are facing now that they're older and not as active as in their youth. How the characters achieved their dreams, what their descendants are doing, who got paired up with whom and the deaths of loved ones are common topics.
** Other stories that take place in the future may also be about the adult lives of characters who are children or babies in the actual series.
* Ever since "The Cutie Mark Chronicles" and "Party of One", Pinkie's straight-haired emo hairstyle has been something of a fixture of the fandom, with the change of Pinkie's mane and tail from fuzzy to straight indicating some form of emotional trauma. Equally frequently is the tendency of writers to refer to her straight-haired form as "Pinkamena" to distinguish it from the puffy-maned Pinkie.
** Combine it with the popularity of {{Fanfic/Cupcakes}} and you have Pinkamena being less depressed and more AxCrazy.
* Diamond Tiara is a ClosetGeek. Or she's at least hiding something that would ruin her reputation. Another common trend involving her would be having to move in with the Apple family and having to deal with Applebloom.
* When ''A Canterlot Wedding'' aired, a lot of people were disappointed with how the inevitable fallout from [[spoiler: Twilight's outburst at the wedding rehearsal]] was just casually brushed aside. Deconstructions of the episode, [[Fanfic/TheNuptialverse ranging from the rest of the cast (and occasionally Twilight as well) still feeling guilty about the whole thing]] to [[Fanfic/FaithAndDoubt Twilight going completely nuts about it]] cropped up almost immediately. A subplot would usually include mention that the kingdom nearly getting conquered would serve as a black mark on Celestia and Shining Armor's reputation, especially when they were both warned beforehand and heavily prepared for a threat, usually leading to rebellions or a call for Celestia to step down, with some more darker stories having Celestia tried for treason (with or without a guilty verdict and/or an execution).
* Ever since the Pinkie Pie-centric DarkFic ''{{Cupcakes}}'' became a smash hit, slews of fanfics have followed in its footsteps. They typically involve a character turning evil (or turning out to be evil all along), usually for no good reason, and slaughtering one or more other characters, usually for no good reason either. Almost all Mane Six members have at least one popular fanfic with this premise. Rainbow Dash has ''Rainbow Factory'', Twilight Sparkle has ''The Experiments of Twilight Sparkle'', Rarity has ''Rarity's New Dress''. Fluttershy is a variation - her ''Pattycakes'' contains no gratuitous violence, but it's often said to be just as traumatizing than the above fics, if not more so. Secondary characters get this too - Big Macintosh has the infamous ''Sweet Apple Massacre'', Cheerilee has ''Cheerilee's Garden'', and Trixie has ''Trixie's Funhouse''.
** A popular type of these follows the lines of "Twilight Sparkle is destined to turn evil, or is turned evil by by a malevolent force destined to re-take Equestria." These often feature torture/mind rape of the Mane Six and/or the CMC, and an epic quest to defeat her or turn her back to good.
*** King Sombra and his corruption are sometimes involved in this.
** Another popular type is Twilight [[TheStarscream overthrowing Celestia, possibly even killing her]]. [[spoiler: Now that Twilight actually is a Princess herself, the fics have taken a new direction; instead of being like an [[Franchise/StarWars Sith Apprentice killing his master to become the next Sith Lord]], it's more like an assassination]].
* A seventh Element of Harmony being revealed. If an OC is involved, it usually requires a retcon of what happened when they were first used. When an OC isn't involved, Trixie is a common candidate, and with [[spoiler: Twilight being an Alicorn]], the harmony of two pegasi/unicorns/earth ponies is restored.
* While not as common as the others on this page, Mr. and Mrs. Cake's having a unicorn filly and a pegasus colt has fueled more than a few investigatory fanfics.
* Alternate Universe fanfics are quite popular. Either the circumstances of Rainbow Dash's first sonic rainboom (which lead to mane 6 earning their cutie marks), the beginning of Twilight's magic studies (and her relationship is Celestia) or the plot of the pilot episode (how they all became friends and defeated Nightmare Moon) play out rather differently. Alternate histories for Equestria have also been done.
** Before [[spoiler: Twilight became an alicorn]], a number of alternate universe fics posed the question of how different events would be if Twilight had different attributes then usual. Either she was born as a different species, a different gender or other physical, mental or emotional attributes. A different life history where she's an orphan and gets adopted by Princess Celestia is also quite common.
* What with the profusion of princesses in the setting, a very common plot involves one of the princesses holding open court and the various difficulties and adventures that result from the petitions brought before them. Became especially common upon Princess Luna's return in season two and even more so once [[spoiler: Twilight Sparkle became an Alicorn Princess at the end of season 3]]. As often played for humor (ridiculous requests and royal shenanigans) as for drama (princesses angsting over responsibilities, politics, etc). [[spoiler: Twilight-centered fics tend to wind up with both: she's extremely neurotic and a perfectionist, but just what exactly is she the princess of anyway?]]
* Fanmade backstories for characters who have no backstory. [[DracoInLeatherPants Giving villains]] {{Freudian Excuse}}s is particularly common, often by way of {{Shipping}}.
** The Discord/Celestia pairing shows up a lot - a common interpretation is that Discord was good until Celestia rejected him. [[http://cosmicunicorn.deviantart.com/art/discordantly-1-259123093 This comic]] is a prominent example of this trend - [[MisaimedFandom even though]] the author himself stated that he wanted to portray Discord as an UnreliableNarrator who just treated the rejection as an excuse to embrace his true evil nature.
** Due to King Sombra's [[ShroudedInMyth lack of backstory]], he gets this a ''lot''. Many stories see him corrupted by dark magic, either accidentally or not. A lot of shipping between him and Princess Luna (as well as Chrysalis) also occurs.
** Queen Chrysalis is FetishFuel to many and it's not very surprising that she gets shipped and {{Freudian Excuse}}d a lot. A common motivation has it that she just wants to feed her people, despite canon portraying her as blatantly cruel and sadistic.
** Minor antagonists occasionally receive the treatment as well. Backstories for Gilda featuring Rainbow Dash shipping are particularly prominent.
