History Fanon / MyLittlePony

** When the cast is "humanized" in fanart, Twilight is often given a brown-skinned ethnicity, most often African-American or Indian -- many artists also choose to because the darker skin tone looks best with the palette of purples; one of the most popular pony fanartists, Yamino, also claims Twilight reminds her of a Sri Lankan she once knew -- or just AmbiguouslyBrown. She's also often depicted as wearing lavender sweater vests, usually over white dress shirts, for a generally nerdy or academic look. Twilight usually keeps her hime cut from her pony form but a lot of fan-artists also shorten her hair into a prim-and-proper bob haircut.
** Human Rainbow Dash is almost always drawn as flat-chested and short. She dresses tomboyishly, often in sweatshirts, track jackets (often with goggles) or tank tops; her hairstyle differs more than most other characters, but short ponytails/having an undercut are popular.

** Applejack's blonde hair, green eyes, and Texan drawl mean that she is almost always white, with most fan artists tending to ignore the idea of her having dark skin, and the fact that there ''are'' POC in the south, too. Regardless, she usually wears cowboy-ish clothing (typically with short shorts, no matter how impractical that really is).
** Fluttershy is a StatuesqueStunner, due to being a model and being depicted as a lanky filly. Human Fluttershy is almost always depicted as wearing sweaters, with the sweaters almost always being yellow to match her fur color as a mare, but occasionally green to match her theme of loving nature.

** Scootaloo having leg prosthesics is common as a counterpart to her inability to fly.

* When it comes to the Mane Six's sexualities, Twilight Sparkle (and less commonly, Fluttershy), is often headcanoned to be asexual (though bisexual is also common, the former's mane is even the colors of the bisexual pride flag), Pinkie Pie is almost ALWAYS pansexual (like Twilight, likely because her color scree resembles the pansexual pride flag), Rainbow Dash is lesbian (see above), Applejack will either be completely straight or completely homosexual, and although Rarity is the only one in the Mane Six who has shown attraction to stallions before, only half of the fandom sees her as completely straight. The other half sees her as bisexual, homo/heteroflexible, a hetero/biromantic of any sexuality, etc. Pansexual Princess Cadance is also popular, as the princess of love. Celestia and Luna are often bisexual and have had various female and male lovers over the centuries.

* The presence of an Equestrian nobility is very popular, despite no nobles actually appearing in the show -- there are royals, including the Princesses and the one-shot character Prince Blueblood, and there are a lot of rich upper-crust members, but actual titled nobility never appears. These are typically depicted as corrupt, arrogant, racist/speciesist/tribalist (i.e., they're unicorns and look down on non-unicorns or -alicorns), and generally shallow and conceited. They're also constantly angling for tax breaks in Celestia's court.

* Due to their interactions in ''School Daze'', fans potray Thorax as Ocellus uncle or older brother.

** Princess Celestia being SemiDivine or otherwise having access to godlike magical power. This originated during seasons one and two, where a very sharp divide was visible between Celestia and all other ponies, and very little was known about her besides her being immortal, moving the celestial bodies, and being associated with a lot of heavenly and angelic imagery. As the show went on, however, Celestia never really demonstrated magical power beyong the bounds of the show's other various powerful beings -- the movement of the sun and moon was replicated by others, she lost most fights she got into, and magical attacks affected her the same as anybody else. The only exception to this was her evil counterpart, Daybreaker, claiming that she secretly knows that she's strong and doesn't need Luna, but Daybreaker was a figure in the nightmare of another character who isn't portrayed as being very close to Celestia anyway. Ultimately, Celestia in canon is portrayed as a teacher and adminstrator first and foremost, and there is very little emphasis on her personal magical might.

** The gray pegasus extra in ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Spotted with [[FishEyes wonky eyes]] in a very brief shot, she was quickly embraced by the show's adult viewers as "Derpy Hooves" and cast by one fanfic writer as a mail carrier. There are varying interpretations of her personality (though generally she has always been a CuteClumsyGirl), but her name and occupation are generally agreed on. %% Let's not bring up her... appearance in "Feeling Pinkie Keen" until we can properly gauge the fandom's response to it.
** Frequently, Derpy has a daughter named Dinky Hooves, a greyish-purple unicorn with a blonde mane that first appeared in "Winter Wrap Up", and is a {{Good Parent|s}} to Dinky and [[MamaBear extremely protective of her]]. Occasionally her daughter will be the child of either Pokey Pierce, his PaletteSwap Ponet (who is also a purple unicorn with a blonde mane), or another background pony. If shipped with Doctor Whooves, she'll be the adopted daughter of his. Although the show itself seems to insist quite clearly that Dinky Doo is the daughter of Carrot Top[=/=]Golden Harvest and Written Script, fans of the show ''insist'' that Dinky is Derpy's daughter. Mostly, it's because Dinky ''looks'' so much like a younger Derpy.

* [[BurlyDetectiveSyndrome Lavender Unicorn Syndrome]] is a fan term used to describe the tendency of fan fiction writers to refer to characters by their description as opposed to their name. Specifically, writers will often call Twilight Sparkle "the lavender unicorn".

* Pinkie Pie having ADHD, depression (and she [[StepfordSmiler acts happy to cope]]), or bipolar disorder.

* Applejack being depressed and being a StepfordSmiler.
* When characters have emotional breakdowns (such as Pinkie Pie falling into a slump in "Party of One" and Twilight having a nervous breakdown in "Lesson Zero"), it's speculated to be [[SanitySlippage actual temporary insanity]] as the result of the pony's special talent failing, dubbed "Cutie Mark Failure Insanity Syndrome".

** Frequently, Derpy has a daughter named Dinky Hooves, a purple unicorn with a blonde mane that first appeared in "Winter Wrap Up", and is a {{Good Parent|s}} to Dinky and [[MamaBear extremely protective of her. Occasionally her daughter will be the child of either Pokey Pierce, his PaletteSwap Ponet (who is also a purple unicorn with a blonde mane), or another background pony. If shipped with Doctor Whooves, she'll be the adopted daughter of his. Although the show itself seems to insist quite clearly that Dinky Doo is the daughter of Carrot Top[=/=]Golden Harvest and Written Script, fans of the show ''insist'' that Dinky is Derpy's daughter. Mostly, it's because Dinky ''looks'' so much like a younger Derpy.

** Derpy is frequently Doctor Whooves' companion; if not, Twilight Sparkle or Colgate (Romana) takes that role.

** Derpy (sometimes Doctor Whooves) is often portrayed as being the leader of the secondary six, a group that consists of herself, Whooves, Lyra, Bon Bon, Octavia, and Vinyl Scratch, even though these characters haven't been shown all together and are often split into pairs (Derpy and Doctor, Lyra and Bon Bon, and Octavia and Vinyl).

** Lyra's profession is usually given as being a harpist. Due to the "[[StarvingArtist impoverished musician]]" cliche, Lyra is often written as having difficulties getting work.

** Because Trixie was originally written as a male character, fan-works about her being trans pop up.

* In many fan works, especially in the shipping fics, lesbian ponies are called "filly foolers" or "mare munchers" while gay ponies are "colt cuddlers" or "stallion stuffers". This can be a hateful slur (like "dyke" or "fag) or a polite but informal term (like "gay" or "lesbian"). "Jackmare" (a jack is a male donkey) and "gelding" (a castrated horse) are less often used as the equivalent of "dyke" and "fag".

** Human Diamond Tiara is occasionally drawn as Latina due to the fact she had a cutecenera (a party thrown for her cutie mark acquisition, which is a pun on "quinceneara", which is a term for a Latina girl's fifteenth birthday).

* On a more {{Squick}}-ish part of {{Fanon}}, it's a popular belief that Applebloom is [[BrotherSisterIncest Applejack's and Mac's child]], and that [[FamilyRelationshipSwitcheroo Sweetie Belle is Rarity's illegitimate child with someone]]. Since the airing of [[Recap/MyLittlePonyFriendshipIsMagicS2E5SisterhoovesSocial "Sisterhooves Social"]], it's been revealed that Rarity and Sweetie Belle were not raised by mules, and that not only is Sweetie Belle not Rarity's child, she lives with hers and Rarity's parents!.[[Series/HomeAndAway That hasn't totally displaced the "Sweetie Belle is Rarity's illegitimate child" bit]], although it required fanon-holders to get a bit more creative about it.

** Princess Celestia, aka [[AlternativeCharacterInterpretation Trollestia]] or [[FanNickname Molestia]], is behind ''everything''. (Except Discord.) Despite her godlike power, she is largely hands-off for most of the events in the series, but just about ''any'' unusual negative event where the Mane Cast learns a lesson about friendship is laid at her feet by some fan or another.
