What they look like: e621.net/post/show/362133/

Spike was currently re-shelving some books Twilight had wanted him to put back. What he didn't notice was a certain book in the pile lightly glow. It was a book on teleporting and portal magic.

As he idly grabbed it, he noticed the book seemed to shake in his grip.

"Whoa! What's happening?! Ahhhh!" exclaimed the young dragon as a swirling portal appeared from the book and sucked him in.

Suddenly, in his place was a creature that seemed to be an amalgam of various animals. This creature was Discord, a draconequus, a creature capable of warping reality with a mere thought that loved to cause chaos.

"Hahaha! Have fun Spike, I know I will." said the chimeric creature, as a TV suddenly appeared in front of him, as well a bowl of popcorn and a soda.

Spike screamed as he was pulled through a weird tunnel of different colors before landing on some ground.

"Ow." said the dragon as he looked around. He appeared to still be in the library, but it looked like it hadn't been cleaned in a long time.

After leaving the library, he saw that it was night and the town was deserted, there weren't even any candles or lights on.

"Okay, this is really weird." he remarked heading into town. As he looked around, he thought that he saw something in the shadows, but when he went to check, there was nothing.

The clouds of shadows rushed to their queens castle to quickly report about the dragon.

=NightMare Castle=

We find ourselves in a large chamber of a dark, but surprising cozy seeming, castle. In said chamber were six larger-than normal ponies. These were the Mane 6, or rather, what used to be the Mane 6.

Each one wore their element around their necks, but where there was originally gold, was black steel, with the Elements being darker than before.

The girls, or rather women, looked at the servant who had appeared, and looked to the one known as Fluttershy, whose skill with animals allowed her to pretty much understand any, no matter the species. Though nowadays she had an affinity for darker ones.

"He says an odd dragon has appeared in town." she translated for them.

"Which one dear? There are lots of towns. And what is so strange about a dragon being in one?" asked the one known as Rarity, a fashionista and self-proclaimed 'lady' by nature.

"Ponyville, and this one has green spines with purple scales." finished Fluttershy.

All of the other girl's eyes widened at that. Their leader immediately looked at the creature before saying, "Describe this dragon more, and where did you first see him?", the way she spoke sent shivers down the beings spine as he spoke to the queens.

Fluttershy's eyes widened as it did as it was told, Fluttershy made sure to translate each word. "This dragon was small and looked like a baby with green eyes. He came from your old library and looked lost and confused."

"Ya'll don't think?..." questioned the dark yellow-orange mare with a slight country accent as she looked at the others.

"It can't be! That thing must be blind!" yelled a cyan pegasus with rainbow mane and tail.

"I enjoy a good joke, even dark ones, but there is a limit." said the pink one with a poofy tail and mane in an uncharacteristically serious tone as she, out of nowhere, brought out a cannon, aiming it at the creature, which looked very nervous, and started grunting and growling at the translator.

"He says he is serious and swears he can bring him to us." translated Fluttershy.

"Do it." stated the leader of the group, with all the other giving looks that said the same. The creature then turned into a shadow and rushed it's way out of the room.

After the creature had left, the horn of the Alicorn of the group glowed as a small section of the walled moved to reveal a purple and green statue made of precious stones, mainly amethysts and emeralds. This statue bore a great resemblance to the dragon that the creature had spoken of.

"I still doubt it." remarked the cyan pegasus.

=Back to Spike=

The purple and green dragon was getting worried, he started out by calling out the names of the various ponies, even looking in some windows. The city was completely barren, aside from the moving shadows, which were seriously freaking him out and making him think he was going crazy, and not Pinkie-Crazy either.

What he didn't see were a few shadow clouds coming up behind him.

"Hey Spike." said a voice behind him suddenly.

"Ahhh!" yelled the young dragon, as he turned and saw his friend Twilight Sparkle.

"Twilight, what's going on? Where is everybody?" asked Spike.

"I think I see Rarity over there." smiled 'Twilight' pointing opposite of her.

"Rarity?! Where?!" exclaimed the excited dragon, hoping to see his crush, when he didn't see her and was about to ask his friend where said crush was, he felt a pain on his head, then all was black.

'Twilight Sparkle' then transformed into a cloud of darkness, that bore some resemblance to a shape-shifting creature called a changeling. Said creature smirked and put the young dragon in a burlap sack, before merging with a nearby shadow and vanishing.

=Canterlot Castle=

Twilight and her friends were getting agitated from how long it was taking, and that's when the changeling appeared with the sack.

"Well?" said the rainbow-maned pegasus of the group.

The changeling gently took the knocked out dragon out of the sack and gently placed him in front of them to see.

They noticed a small lump forming on his head and turned to the shape-shifter.

"I had to knock him out," defended the changeling covering under their gaze. “,otherwise he would have put up a struggle!"

They then dismissed him, he walked out of the throne room with a sigh relief, before he was suddenly blasted in back by a magic-beam and into the opposite wall as the door slammed shut.

Twilight's horn dimmed down as the girls surrounded the dazed dragon/.

The alicorn of the group summoned a very luxurious and comfortable purple and black colored bed. Said alicorn used her magic to gently levitate the dragon onto the bed.

"Wha-What's going on?" groaned Spike rubbing his head.

The girls decided to not scare their friend, and transformed back into their original forms.

"Spike, are you okay?" asked the purple alicorn.

"Twilight?" groaned the dragon.

"Oh, my little Spikey-Wikey, what happened to you?" asked said dragon's crush.

"I don't know, one minute, I'm looking around for anyone in Ponyville, the next everything's black and pain." said the dragon as a he hissed as he touched his new lump. "Speaking of which, what happened to Ponyville? Everyone's gone, and it looks like it's been abandoned for months." inquired the curious hatchling.

Thinking fast, Twilight came up with an explanation. "Well you see, months ago, Queen Chrysalis somehow took over the Everfree Forest, then suddenly attacked Ponyville, and we had to help everyone else escape, by the time we got back with the Element of Harmony, it was too late. Luckily she's satisfied with Ponyville and the surrounding area." 'explained' Twilight. "Where did you come from, though, you've been gone for nearly a year?" asked the purple-furred mare.

"A year? I just got here." replied the dragon.

"What's the last thing you remember, before coming out of the library?" asked Twilight.

"You told me to put the books back, one of them glowed, and for some reason the place was real dusty."

"Do you know what book it was?" continued the duel-haired princess.
"No. I didn't see the title." “, but I think it said something about teleporting and dimension, or something like that."

Twilight nodded at his answer, knowing what book he was talking about, it was basically on how the various magical forms of teleportation might affect other dimensions. Though as far as she knew, it had no magical properties.

‘If that's true, than this Spike is from another dimension.’ “While ours is still-" she looked down at the memory of what happened to him.

"Still what?" asked the now worried dragon, nervous about their depressed looks.

"On Vacation!" shouted Pinkie all of a sudden, startling Spike.

"Yeah, we sent you on vacation, about a week before Chrysalis invaded, so we made sure you stayed there to keep you safe." explained Twilight, catching on to what Pinkie was doing.

Spike gave them a raised eyebrow look at the explanation and merely shrugged his shoulders. "So, anything else interesting happen?" he asked, mainly looking focusing on Applejack, who for some reason blushed at his look.

"Nope, nothing at all!" she said in her typical lying manner, in other words, so badly, even a 5 year could tell she was lying. The other ponies face-hoofed at this.

Spike crossed his arms as the other girls could tell Spike knew Applejack was lying.

Twilight exhaled a sigh as she asked him to wait as she and the other huddled and started talking, something about 'telling him the truth', him freaking out and being scared, and blaming Applejack, with her blaming her honest nature.

Spike was confused as the girls broke away from their huddle.

"Um, Spike, try not to freak out, okay?" Twilight said nervously, causing him to get nervous himself, he didn't even notice that door and windows lock themselves while glowing purple.

"Why would I freak out?" he asked nervously at how they were acting.

The girls all started to glow and grow before his eyes, his eyes widened, they all became around the same size as Celestia, their hair had grown practically floor length, and the color of their fur and manes had darkened considerably. However, it was Rarity that shocked him they most, not that she became scary, but the form she had was 'very' familiar. That of Nightmare Rarity.

He involuntarily stepped back as he could feel some strange power emanating from each one. It was the power of the Nightmare Essence. The same power that had corrupted Princess Luna over a millennia ago, as well as his crush only a few months ago.

He turned and was ready to bolt, but was held in place due to Twilight's magic.

"Whoa there Spike, where do you think you're going?" asked Twilight.

"Uh, outside?" spoke Spike in a nervous tone.

"No, you're not." said Twilight in a light, but commanding tone as she used her magic to put him back on the bed.

Spike gulped as he took a moment to try and understand what happened to his friends. From how they were acting, it seemed like they didn't expect him to know what Nightmare Rarity looked like, so either it never happened in this dimension, or he wasn't involved for some reason.

"This Spike is definitely not ours." whispered Rainbow to Applejack.

"Yeah, he's acting like we'd eat him faster than a mouse on cheese." replied the country mare.

"Okay, what's going on around here?" asked Spike who wanted answers. "Why are all of you Nightmare-possessed?!" shouted the dragon, startling the mares with his knowledge of what had happened to them.

"It's a long story." sighed Twilight.

Spike gave her a look that pretty much demanded that she explained. The fierce look in his eyes caused the girls to feel a warmer.

"Well, our Spike didn't go on vacation." admitted Twilight.

The way they all looked depressed made him feel more nervous than he had in a long time, not since their fight with their last big bad.

"He died!" cried Rarity who covered her eyes with her hooves as she couldn't stop the tears from coming out.

"WHAT?!!" shouted the freaked out dragon at the news of 'his' death.

Fluttershy was the next to cry as both her and Rarity turned on the waterworks.

"In your world, have you fought a being known as Tirek yet?" asked Twilight, whose eyes were starting to water.

"Yeah, why?" asked Spike.

The girls all gained angry(and envious?) looks in their eyes. Twilight asked Spike to explain how the fight in his dimension went, he say no harm in it and did so.

After he was done, the girls still looked angry.

"S-so, what happened here?" the now, once again, nervous Spike.

"That bastard killed you just to distract me." growled Twilight.

Spike's eyes widened in shock at the news of his counterparts death and asked what that had to do with their transformation.

"It made us all dark and gloomy like this." piped in Pinkie.

"After Tirek killed you, we were all distracted and he escaped." explained Twilight as tears started coming out of her eyes. "That night, after your funeral, something visited all of us, we didn't know what it was at the time, but we were promised power, the power to protect our friends and family from everyone, and the power to avenge your death." she finished with a scowl on her face at them memory, the other ponies all had similar looks on their faces, even Pinkie and Fluttershy.

"So, what happened to everypony?" asked Spike.

Pinkie Pie popped up in front of him suddenly, startling him. "Welllll, after taking care of the big red meanie, we decided to take over the world!"

"WHAT?!" exclaimed Spike in shock.

"After you died, we decided that enough was enough, and while Princess Celestia is a good ruler overall, her pacifist nature makes every believe that we're all pushovers. That is part of the reason that we have been invaded so often and are the target of pretty much everybody." explained Twilight.

"So we took over and made sure all of our families were safe." continued Applejack.

"And we made sure that no one would want to mess with us and ours!" went Rainbow Dash as she hit her hooves together.

Spike gulped in slight fear. "Wh-where is everyone, like Big Mac and the Cutie Mark Crusaders?" asked Spike.
"They're all in the city Spikey, though Applejack's family still insist on living in the countryside on a new apple-farm, for whatever reason." spoke Rarity.

"They want to have something do and not just laze around all day, like a certain cat we all know." explained Applejack with an annoyed tone that said that they'd done this before.

"So, what happens to me?" asked the dragon.
"Isn't it obvious my little Spikey-Wikey, you stay with us in the castle. In fact, you can stay with me in my room." said Rarity as she hugged Spike, who blushed as contact of the more mature form of his crush.

"I think Spike should bunk with me." spoke Fluttershy pulling the dragon away from Rarity and to her chest.

*Whoosh!* "No way! Little guy's staying with me!" Rainbow Dash shouted down from a balcony after taking Spike.

"Nope!" Applejack swung a lasso up and pulled Spike to her. "He's stayin in ma room."

*Boom!* The party cannon blasted Applejack into the wall, somehow missing Spike, who was just picked up by Pinkie. "Sorry, but this little bundle of fun is mine for the night."

Said dragon was yanked from her by Twilight's magic. "Nope. I've known him longer."

*Glow!* Spike was suddenly glowing purple, then flew into Rarity's arms once again. "Now now dears, Spike obviously wants to stay with me." said Rarity primly.

This continued for a bit longer, each pony taking Spike from the other in their own unique manner, with Twilight being the only one not doing anything. A few more minutes passed before said pony signed before using her magic to freeze all of them.

"Girls, have you forgotten what tonight is?" said Twilight in a kind manner, with only a twitching eyebrow portraying her feelings.

It took a minute for the other ponies to get what she was saying, when Pinkie shouted "Sleepover Night!!!".

The other mares smacked their heads at that.

Sleepover Night, was something they did after they took over the Canterlot Castle, it was done so that they could discuss more innocent times and such at first. But it eventually become something that had them get a LOT more personal and close than expected, thus leading to its second name, Orgy Night.

Spike figured they were just being girly over a sleepover.
A few minutes later they had been teleported to a room that had six beds, each one was easy to tell who is belonged to, by its coloring and design, but in the middle was one large bed, that looked to be made of some very fine material, and there was a mirror on the ceiling for some reason.

Just as he was about to ask what the mirror was for Twilight gave him perhaps the most heated kiss he had ever received. After she released him to let him breathe, Rarity grabbed him and did the same, it continued until each one had a turn, then they had started kissing each other, much to his embarrassment. And it just kept getting steamier and more intimate from there.

(Omake)

Discord was chuckling as he continued to watch from the TV he had conjured up.

Discord's ears increased in size as he heard a familiar set of voices talking and snickered as he imagined their reactions to the young dragon's 'situation'.

"Discord? What are you doing here?" asked Twilight as she and her friends entered the castle. “And where's Spike? He said was going to do some organizing." said Twilight

"Why don't you take a look for yourself?" said the mischievous reality-warper, gesturing to the TV. The reactions were all about what he believed they would be.

Rarity made a loud gasp while fainting on the spot.

Fluttershy let out a small 'eep', becoming redder than Big Mac's fur, before fainting as well.

Rainbow Dash's eyes widened as her wings unfurled.

Applejack immediately lowered her hat to hide her massive blush.

Pinkie let out an "Ooh" while jotting down notes.

Twilight's eyebrow was twitching as she frowned, before taking deep breath and releasing her opinion on Spike's situation out at Discord.

"WHAT THE HELL IS GOING ON?!" she yelled, unconsciously using the Royal Canterlot Voice.

Discord shook his head, making some random items fall out of his ears. "I simply decided to send Spike on a little vacation." he said an 'innocent' smile, even having a halo over his head.

"I repeat, WHAT THE HELL DID YOU DO!?", this time waking up the ponies that had fainted.

The yell sent the halo flying into wall behind Discord and ricocheted it onto the back of his head, which he rubbed irritably.

"It's just as I said, I sent him on a small Pleasure Vacation." he re-explained, getting glares from all of the ponies in the room.

"Bring him back!" yelled Rainbow.

"No can do, sending the little dragon took a lot more out of me that I thought it would. So you'll probably wait about, hmm, a week until I can summon him back. Unless 'you' want to inter-dimensionally summon him? Fair warning, to summon a specific person, requires a 'very' precise magic, no matter the form it takes." explained the trickster.

Twilight gritted her teeth while Pinkie continued to take notes from the TV.

"And if I didn't know any better, I'd say you're jealous of your counterparts." said Discord.

"Counterparts?!" exclaimed all of the Mane 6.

"Those six are you from another world." grinned the spirit of chaos with a chuckle.

They ponies then took a look at one whose form was 'very' familiar, having done battle with 'her' only a few months ago.

"Nightmare Rarity?!" gasped Applejack.

Fluttershy 'eeped' as she quickly hid behind the other pegasus in the room.

"Wow! Fluttershy's counterpart is really flexible!" called Pinkie with a pile of notes beside her.

"Pinkie! You're embarrassing her!" shouted the blushing blue-furred pegasus.

"I say sit back and enjoy." smiled Discord sitting in the air while watching the TV.

Rarity and Applejack were facing the opposite wall blushing, with Rarity saying stuff about 'evil witches corrupting my sweet innocent Spikey-Wikey'.
