''[[http://www.fimfiction.net/story/138303/curse-of-the-demon-pony Curse of the Demon Pony]]'' was a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' story by Website/FanFictionDotNet author Creator/JusSonic.

Set two weeks after the events of the season two finale, Twilight Sparkle and her friends are invited back to Canterlot to participate in the "founding ceremony." While there, they learn a demon pony is on the loose, and that it may have a connection to Twilight's lost love...

This was the first of several stories in the author's universe, followed by ''Fanfic/BensFirstDay'', ''Happy Birthday, Nyx'', ''FanFic/BlackPonyOfTheFamily'', and ''Lorcan's Wrath'', as well as the side stories ''The Return of an Old Friend'' and ''Lorcan's Rage''. More stories followed soon after, even going as far as crossover, such as [[FanFic/TotalDramaEquestria ''Total Drama Equestria'']].

As of 2013, Creator/JusSonic has been banned from Website/FanFictionDotNet, so this story and all of the others by this author no longer exist on said site.

----

!! The following story contains examples of:

* AbhorrentAdmirer: Boris for Twilight. Not that he notices.
* AccessoryWearingCartoonAnimal: Ben is mentioned to only ever wear a red collar, a gift Twilight got him as a colt. [[spoiler: This is how Twilight realizes he's the Demon Pony]]. Despite this, Boris also threatened to give him a wedgie back in the past. If he doesn't wear pants, let alone underwear... Perhaps one shouldn't think about that too much.
* AerithAndBob: Boris' and Ben's names really don't sound like they belong among the other characters' names.
* AsYouKnow: A pair of pegasus guards helpfully inform the hiding Crusaders (and the readers), about that mysterious locked room in the Eastern part of the palace that Princess Celestia doesn't let anyone enter, and can only be opened with alicorn magic.
* TheAtoner: Spell Nexus (from ''Fanfic/PastSins''), who still feels bad about that whole "bring back Nightmare Moon" thing.
* BerserkButton: Don't ever say anything bad about Ben Mare (and oddly enough not her friends or adopted daughter) around Twilight, or she'll transform into [[Franchise/{{Pokemon}} Rapidash]].
** Also, demon pony or not, do not ruin Pinkie's games!
** Hurting Nyx is one for Twilight, and hurting Nyx or Twilight is one for the Demon Pony, as Boris found out the hard way.
** Nyx does not appreciate being called Nightmare Moon.
** She also doesn't like it when somebody hurts her mom or her friends.
%%* BigBad: Boris.
* BreakingTheFourthWall: At one point, Pinkie talks directly to [=JusSonic=], where she tells him that he means "A filly on her way to a concert" rather than "a girl on her way to a concert".
* BroadStrokes: The author takes elements of ''Fanfic/PastSins'', ''Fanfic/TheElementsOfHarmonyAndTheSaviorOfWorlds'', and ''FanFic/FixingUpMissSmartypants'' and acknowledges they all happened in the show's canon, despite pretty much all contradicting each other.
* BroughtDownToNormal: All the Mane Six (except Twilight), Derpy Hooves and Pony Joe lose their horns and wings thanks to Boris. [[spoiler:They're restored after Ben comes back to life]].
* BumblingHenchmenDuo: Boxco and Dum Dum, Boris' moronic flunkies.
* CallForward: During her flashbacks to her fillyhood with Ben, the story notes how Twilight used to tease Shining about liking Cadence.
* CerebusRetcon: Twilight yelling "Snakes! Snakes!" in "Winter Wrap-Up"? Funny stuff, but this story reveals that, when she was a filly, she was nearly killed by snakes in the sewers of Canterlot.
* ChekhovsGun:
** The flower camera that Rainbow gives Twilight [[spoiler:is later used to record Boris's confession of what he did to Ben]].
** The necklace the Cutie Mark Crusaders find in the palace [[spoiler:restores Ben to life as well as everyone's missing horns and wings]].
* ContinuityNod:
** Many for ''A Canterlot Wedding'' since this takes place after it, including Pinkie again [[GatlingGood using Twilight like a gatling gun]].
** Twilight notes that the pegasus guard that arrives to take them to Canterlot is one of the ones who dropped her off in the pilot.
** Twilight yells "[[WhyDidItHaveToBeSnakes Snakes! Snakes!]]" again, like she did in ''Winter Wrap-up'', only this time, a reason for her dislike of snakes is revealed.
** When trying to keep Fluttershy from learning about that they saw the Demon Pony, the CMC tell her they're playing the "shh game" from ''Stare Master.''
* DarkIsNotEvil: The Demon Pony; he looks and seems evil, but only attacks when he's provoked. [[spoiler: That's because he's Ben, and he has his intelligence]].
* DepartmentOfRedundancyDepartment: One of the story's most frequent criticisms is that it tends to repeat what the characters say after they've just said it.
* DidIJustSayThatOutLoud: "The princesses hired me to get rid of [[spoiler: Ben Mare]] and that's exactly what I'm going to do!"
* DidntThinkThisThrough: After catching the dangerous Demon Pony, the Mane Six left it completely unguarded all night. Guess what happened next?
* DisneyDeath: [[spoiler: Ben]] dies in the penultimate chapter, only to be revived at the start of the next one by a DeusExMachina.
* DraggedOffToHell: As a result of the spell he cast, [[spoiler:Boris]] is banished to some sort of Hell-like realm. [[spoiler:It doesn't last, however, when Lorcan brings him back to serve on his army.]]
* EasilyForgiven:
** Nyx and Cutie Mark Crusaders are told to stay at Twilight's parents' house while the Mane Six go to hunt for the Demon Pony. They disobey them by sneaking out after having drugged Spike. While it does lead to Derpy saving Shining Armour (albeit through her clumsiness), the fact still stands they disobeyed the older ponies. The following morning, they are let off from punishment under the reason that no one was harmed and are allowed to visit Zecora with the Mane Six after Nyx begs Twilight with little effort.
** Nyx, as Nightmare Moon, destroys the Devil's Red Sun before Princesses Celestia and Luna can finish purifying it, leaving the ponies without their wings and horns. None of the ponies hold a grudge against Nyx for what she did.
** The Cutie Mark Crusaders accidentally set of Pinkie's party cannon and blow up Twilight's parents' house at the end of the story. They are not punished for it.
* {{Expy}}:
** Boris is basically a unicorn version of [[WesternAnimation/BeautyAndTheBeast Gaston]]; he has a red coat, is an EgomaniacHunter, has two bumbling Lefou-like sidekicks, and even has a ''gun'' for a cutie mark.
** Speaking of which, his sidekicks are both heavily based on Lefou.
* FantasticRacism: Boris and his goons have an extreme hatred of Earth ponies, believing them to be low class. Naturally, this doesn't endear them to the Mane Six.
* FateWorseThanDeath: Celestia tells Luna that she considers Boris [[spoiler: being sucked into the Void]] to be this.
* {{Flanderization}}: The Mane Six (minus Twilight).
* FlatCharacter: Pretty much all of the original characters in this; especially Ben Mare.
* HandWave: So as not to have to write her [[RhymesOnADime rhyming dialog]], the author has Zecora explain that she only rhymes whenever she's trying to appear strange and mystical (i.e pretty much always).
* InsultBackfire: Twilight calls Boris "primitive" for thinking Nyx is still a threat, which he thanks her for.
* ItsPersonal: Both Twilight and Celestia have their own reasons to capture the Demon Pony, and both involve Ben Mare.
* JerkJock: Boris was kind of this in school to Ben.
* LaserGuidedKarma: [[spoiler:After Ben Mare is restored, Boxco and Dum Dum are sentenced to work as janitors as punishment for their crimes in harming him and banished. The banishment part also extends to Boris.]]
* LockedIntoStrangeness : Boris' hair becomes silver when he's corrupted by the Red Sun.
* TheLostLenore: Ben is basically a male version of this, as his disappearance apparently made Twilight give up on dating completely, fearing that any new love interest would disappear like he did.
* LukeIAmYourFather: [[spoiler:Ben turns out to be Princess Celestia's adopted son]].
* MurderTheHypotenuse: Boris's main reason for wanting to kill the Demon Pony. [[spoiler: He knows it's Ben, seeing as he was responsible for turning him into it.]]
* NarratingTheObvious: This happens a lot.
* OhCrap: Most likely Boris's reaction when he realizes he said [[spoiler: Ben Mare]] instead of "the Demon Pony" in front of Twilight and friends, thus revealing he knew what it was the whole time.
* OneWingedAngel: [[spoiler: Boris uses a forbidden spell to transform into a giant, powerful form, known as a "devil"]].
* ThePowerOfLove: [[spoiler: What activates the [[MacGuffin Love Eternal]] and brings Ben back to life and restores everything Boris destroyed, is Twilight's love for Ben.]]
* PunctuatedForEmphasis: I! Am not! Nightmare Moon!
* RescueRomance: Sort of. When they were young, Twilight protected Ben from bullies (i.e. Boris) and they eventually developed a deeper relationship.
* RougeAnglesOfSatin: Most of the story is written with this.
* SchizoTech:
** Well, in addition to Boris's gun, there's also walkie talkies (although those have been seen before), Rainbow's laptop (see ShoutOut below) and [[ChekhovsGun the flower camera]].
** Boxco and Dum Dum mention a submarine (or "ponymarine") as part of a joke.
* SequelHook: [[spoiler: At the end, Lorcan rescues Boris from the Void and recruits him to join the [[LegionOfDoom Brotherhood of Tadaka]]. The other known members include Gilda and three unicorns (later revealed as Trixie and the Flim Flam Brothers), and they've got a spot reserved for Discord...]]
* ShoutOut:
** Pretty much the whole story is a shout out to ''WesternAnimation/BeautyAndTheBeast'', including the idea of a bookish filly being pursued by an EgomaniacHunter, [[spoiler: the beast destroying a picture of his former self]], and his [[spoiler: DisneyDeath]]. A number of lines are taken from the film, including Twilight using a modified version of Belle's famous line; "he's not a monster Boris, you're the monster!"
** The climax has lines blatantly stolen from ''WesternAnimation/{{Hercules}}'' (specifically, the "What do you call that thing?!" "Two words: AM-SCRAY!" exchange) and ''WesternAnimation/{{Aladdin}}'' (specifically, "Perhaps you'd like to see how ''ssssssssnake-like I can be!''").
** One scene has a pair of guards admit that they're not super-helpful in a major crisis, a slightly reworked version of an exchange between two Stormtroopers in one ''WesternAnimation/FamilyGuy'''s ''Franchise/StarWars'' parodies.
** This fic also has some references to ''WesternAnimation/TheCurseOfTheWereRabbit'', including the title.
** It also contains references to the author's ''Rainbow Dash e-mails'' and ''Dasheresque'' fics, both of which are basically ''WebAnimation/HomestarRunner'' [[RecycledInSpace with ponies!]]
** In one of the battles, when Fluttershy summons animals for help, "The Immigrant Song" by Music/LedZeppelin is said to be playing. This is taken directly from [[WesternAnimation/{{Shrek}} Shrek The Third]] since it's the exact same thing that Snow White did in that movie (because let's face it, the author's probably never even heard of Led Zeppelin outside of that movie).
** When Ben [[spoiler: is brought back to life]] near the end, his cutie mark is [[Franchise/TheLegendOfZelda a triforce]].
** The "ponymarine" joke was taken from 'Film/BackToTheFuturePartII''.
** A later chapter also has the "shoot you like a duck" joke from ''Film/BackToTheFuturePartIII''.
** One of the most famed lines from ''Film/{{Scarface 1983}}'', of all things, is (sort of) used at one point.
--> "Say hello to my little unicorn friend," Pinkie said in a weird gangster like voice.
* SurroundedByIdiots: They may be loyal, but Boxco and Dum Dum are constantly screwing up Boris's plans.
* TemptingFate: At the end, the CMC decide to try out Pinkie's new upgraded party cannon, wondering what would happen. [[spoiler: They end up blowing up the Sparkles' home, forcing them to move into the palace for a while]].
** Also when the CMC are walking through the streets of Canterlot at night, Nyx comments that everything has been fine moments before the Demon Pony finds them. Scootaloo even says "You had to say it, didn't you?"
* TookALevelInDumbass: Twilight Sparkle unintentionally comes off as a moron for some of the story.
* VillainWithGoodPublicity: Boris. He's a self-centered jerk with a hatred of Earth ponies, yet its' acknowledged that he was a big help during the Changeling attack, the princesses accept his idea (only after it appears that the Mane Six have failed), and he's easily able to persuade the ponies of Canterlot to go after the Demon Pony. [[spoiler: By the end, he's lost the "good publicity" part]].
* WhoNamesTheirKidDude: [[LampshadeHanging Lampshaded]] in the story by Apple Bloom, who notes that "mare" is a female pony term. Twilight tells her that Ben was teased because of that. [[note]] One of the author's later stories revealed his name is actually "Maregillian," but Celestia couldn't fit that on the birth certificate [[/note]]
** Maregillian? I don't know if that's better or worse.
* WouldHurtAChild: Boris has absolutely no problem trying to kill Nyx if it means getting the Demon Pony. This comes back to bite him later.
* WhatHappenedToTheMouse: Just what the hell is a Miniwere and what happened to it after it attacked Ben?!
