The Movie starts with our story opening on a dark and creepy full moon lit night, the Mane 6 plus Spike are wondering around a creepy old graveyard, naturally Rainbow Dash is trying to take advantage of the situation my acting scary.
"Full Moon lit Night, Spooky Atmosphere, Creepy old Cemetery, this would be the perfect place to tell some Scary Stories" Rainbow Dash boasts and finishes with a creepy evil laugh "Muh-ha-ha-ha-ha-ha".
"Knock it off Rainbow Dash" says AppleJack, "This ain't the time fer that".
"So, remind me again why we have to be in a creepy old graveyard in the middle of the night?" Fluttershy asks as she turns to Twilight.
"Because Princess Celestia sent us here to meet somepony making a special delivery of absolute importance" said Twilight to not just Fluttershy but the rest of the gang as well.
"Well I wish that they could have had the rendezvous point be somewhere a little less Terrifying" says Spike while he's latching himself onto Twilight's leg, trembling in fear.
"Oh I Agree" said Rarity to Spike, then while trying to shake some dirt off her hoof she complains "This place is just filthy and oh so drab, the groundskeeper really needs to do a better job around here".
Naturally Pinkie Pie tries to make light of the situation by trying something weird like make a puppet show out of nothing but some sticks, rocks, leaves, vines & moss, where she uses sticks as the bodies, rocks as heads with faces drawn on them using mud, leaves & moss as clothing, and vines as strings to control them like marionettes, and moss as a curtain, with some big rocks or broken tombstones as a stage, or some other weird Pinkie Pie thing like that, then at some point when Pinkie turns around facing behind herself, Rainbow Dash wearing a bug-bear face mask stands right up to Pinkie's Face and goes "BOO!" .
Scaring Pinkie so bad that she jumps up through a cloud in the sky leaving a hole in the shape of her body, and the camera is in the right position for the opportunity to have Pinkie break the 4th wall right in front of the camera, "Ooh, I can see the whole audience from up here" says Pinkie, "Too bad this movie isn't in 3-D, am I right?" she says as she falls back down leaving a new hole in the same cloud, only to have a soft landing thanks to a thick moss covering a dead bush.
Then Rainbow with the mask still on her face starts laughing hard at that, the others are all aggravated at R.D. right now, then as R.D. is enjoying the moment, a wisp of shadow-like smoke comes out of the ground right behind her, then it takes the form of a humanoid, demonic-looking creature with bat-like wings, small devil-like horns on it's head, a pig snout-like nose, a mouth full of fangs, clawed 4-fingered hands, pointy ears, glowing red eyes, rough dry skin as pitch-black as coal, and stands about the same size as the ponies are when they stand up on their hind-legs, sneaking towards Rainbow from behind her.
The others see the creature behind Rainbow & try to warn her, but they're so freaked out that they can't even form a single word, so they keep pointing to the monster behind Rainbow, Rainbow is confused saying "Come on girls, it wasn't that bad", a second later she asks "What's up with you guys?", then another second later she figures it out and points the tip of her hoof behind her while saying "There's something bad right behind me isn't there?", she turns around, then she freaks out while zipping away from the creature as it slashes it's claws and turns her bug-bear mask to shreds without even touching Rainbow, because she was so freaked out, that she moved so fast, that the mask just popped right off her face & temporarily floated in mid-air just long enough for the creature's claws to make contact with the mask.
Our heroes then try avoiding the creature's attacks as it chases after them acting like a feral beast, suddenly a strange glowing, spinning disk-like object comes flying towards the creature, then when it makes contact with the creature, the creature turns to smoke & evaporates into nothing, the disk-like object then passes through the evaporating smoke a second time, then it stops right beside the face of a mysterious figure, a male pony with a pale-colored coat of fur, a tall yet thin body figure like that of the Flim Flam Brothers or Cheese Sandwich, with a short haired tail & an almost completely bald hairdo similar to that of Curly Howard from the Three Stooges, wearing pieces of some kind of armor on certain parts of his body, plus some belts with pouches meant for carrying stuff, and some scabbards set in an X-shape on his back holding a pair of swords, and wears a set of reflective sunglasses that make it so we can't see his eyes, he also has a cutie mark depicting a coat of arms with a pair of swords, but the biggest thing about this strange pony is the fact that he has not just one, but Two Unicorn Horns on his forehead, both about the same length as Prince Blueblood's or Shining Armor's, and are lined up with one in front of the other, positioned at about a thirty-degree angle of separation from each other, once the disk-like object stops, we see that it's a 4-prong shuriken throwing star being held by levitation magic with a Platinum colored aura, the Mane 6 then gasp at the mysterious imposing stranger, then at a close up of the stranger's face, he then says "Run!" in a deep, serious toned voice that sounds like the one that Steve Blum used in his voice-over for Marvel Comics' Wolverine.
Then Fluttershy begins flying away while saying "You don't have to tell me twice!", but before she can escape two more of those exact same creatures appear above her, then she squeals in terror & heads back down.
Then several more creatures appear all around the ponies, the stranger leaps in and everyone forms a circle, looking at the swarm of creatures as they keep coming closer & closer, Applejack says "What the hey are these things?!".
"Ghosts?!" says Rarity.
"Zombies?!" says Spike.
"Dark Goblins!" says the stranger.
Then as the Goblins begin charging in we see Pinkie Pie saying "D-Duh-Do-Dee-Doh-D-" and she places her hooves on her cheeks in the style of Macaulay Culkin from the Home Alone movie and shouts "DARK GOBLINS!!!", then we cut to the opening title sequence.
During the opening sequence we see the My Little Pony logo & hear the theme song, but the song is being distorted as the logo begins cracking with some smokey-shadow like substance coming out of the cracks, then the logo is shattered as a deformed silhouette of what looks like a ram-like being is shown looking at the camera with glowing red eyes, then it raises it's hoofed fore-limbs & a huge shadow consumes the land with deformed versions of the Dark Goblins running loose around the area, then we see some staff credits of the cast & crew, then it all gets engulfed in shadow, then we see deformed versions of Ponies running away from the encroaching shadow consuming all in it's wake, as all this goes on we see more staff credits as it's all being consumed by shadow, we also see dark goblins wreaking havoc, one of them slashes it's claws at a pony, only to have it miss & we see some staff credits in the claw-marks, later as we see deforms of the Mane 6 completely surrounded by shadow & dark goblins, when all hope seems lost, a bright ray of light shines so bright that it repels the shadow & destroys those dark goblins, then the deformed Mane 6 look to the source of the light to see a deform of the two-horned pony/stranger from earlier, the stranger then fires a huge magic beam from his horns and blasts the shadow away revealing more staff credits, as a swarm of dark goblins form a tidal wave about to hit the stranger, he takes out one of his swords and slices the tidal wave right down the middle, causing it to dissolve into nothing, then the stranger levitates out a bunch of throwing stars, then the throwing stars mow right through the shadow like a lawn mower, revealing more of the staff credits, when more dark goblins dive bomb the stranger from above, the stranger levitates what looks like a chain, then spins it around to form a vacuum funnel that sucks the dark goblins in, then the stranger slams the funnel on the ground, destroying all of the dark goblins that were in the funnel, the imprint left on the ground reveals more staff credits, after clearing a bunch of the shadow & getting rid of a lot of the dark goblins, the stranger heads towards the ram silhouette, then the ram silhouette fires a dark magic beam, and then the stranger fires a magic beam of his own, when the two magic beams hit they create a huge flash transition, then we see the deforms of the stranger, the Mane 6 & the ram silhouette all right above the movie's title which states "My Little Pony: the Last Twonicorn".
