Our story begins long ago after the defeat of Nightmare Moon. The kingdom has faced another threat to pony kind…In the realm of Glacies, unicorn guards broke into a temple. An ice pony glared at them in the shadows as they stormed in.

One of the guards snapped, "Laufey? By order of Princess Celestia, you are under arrest for your crimes against Equestria."

"Fools! You won't defeat me so easily!" Laufey snarled as he charged to attack the guards.

They dodged his attacks quickly and tied him up with magical ropes, dragging him away to some unknown location. But not any of them noticed the young ice pony colt hidden behind a column. Princess Celestia sighed as she looked at the remains of what used to be the Ice Pony Temple. Not so long ago, the battle between the ice ponies had ended.

"I should've let him escape when I had the chance…" Celestia muttered, flying around the temple. "Nothing remains here, except—"She stopped as she wound up behind a column and saw something: an Ice Pony colt, about the same size as a normal pony foal, was cowering behind it.

Celestia used her magic to lift the scared foal up and examined it. "This must be Laufey's son…I have to tell the Ponyheim army at once. Odin must know about this foal…he must have a better life and not know about his true parentage." She muttered. With that, Celestia ran off with the foal in tow.

In the present day…"Run, Twilight, Run!" A voice called out as a young unicorn filly known as Twilight Sparkle ran away. She looked back in terror as the one yelling to her was following closely behind, but was levitated off by a mysterious attacker. "Foolish filly, you cannot hide from me!" An evil voice hissed in a dark British accent. Twilight can only watch in horror as the one talking in the dark voice fired a knife and killed the filly who told her to run. "Dinky, no!" Twilight screamed, seeing blood on the floor. "NOOOOOOOOOOOOOOOOOOOOOOO!"

"NOOOOOOOO!" Twilight screamed as she started sweating a little. "Ugh, not that dream again…" "Hey, Twilight? What's wrong? Are you having that nightmare again?" A voice asked.

Twilight turned to see that Spike, her assistant/adoptive brother/adoptive son and friend, was standing at her bedside, looking worried. "No, it's not. It's…" Twilight sighed. "Just another nightmare…"

"It's ok, Twilight. I'm here and I'm not going anywhere anytime soon." Spike reassured as he hugged Twilight. She sighed, knowing that it'll never be simple.

In the Canterlot Castle gardens, a unicorn guard was standing in front of the statue of Discord, making sure nopony starts a fight or creates chaos. After the last time, Celestia didn't want it to happen again. The guard felt the area get cold and shivered as he felt a dark presence. He turned and asked, "Who goes there?!" Evil laughter was heard as the guard gasped and saw a dark figure who demanded in a dark British accent, "I need that statue."

That was the last thing the guard saw before darkness cornered the edge of his vision. The guard's body was levitated to the ground with his chest covered in blood as the shadowy figure turned to Discord and fired a spell at the statue. The statue began to crack and fell apart, freeing the lord of chaos and disharmony inside. "Ow! What?" Discord asked, looking around in confusion. "Oh, I'm free again. Thank goodness…Who should I thank this time?"

"That would be me, Discord. I have freed you for a chance to get revenge on those ponies who imprisoned you."

"Really? How should I help you?"

"Let's say that we have a lot in common than you believe so…" The mysterious figure smirked as he pointed his horn to the evil Draconequus's throat. "I can destroy those ponies for you even if you say no. Trust me, I am difficult to fight with."

"Well, you got my attention…" Discord muttered with an amused expression.

Celestia woke up, a noise being heard from her room…and saw a message written in blood that read 'I'm back!' much to her horror. "No…" She gasped. Celestia knew this was going to happen. She ran to go warn her sister and the other guards.

In the Princesses' old Castle, the mysterious figure glanced as Discord joined the other members who were standing in the shadows. "Welcome to my army. Soon, everything shall be done and…" The mysterious figure said evilly. "Hey, boss!" A familiar voice called out. "Can we come out of the shadows? I'm getting tired of standing here."

"Alright, I suppose we are done acting like the 'mysterious ones'."

The figures stepped out of the shadows, revealing themselves to be Trixie (the unicorn who lied to Ponyville about defeating an Ursa Major), Gilda (Rainbow Dash's former griffin friend), Flim and Flam (the unicorn brothers who tried to put the Apple Family out of business), and the Diamond Dogs.

"Why, this is an interesting army you've put together." Discord commented. "Indeed, recruiting them was too easy. I sent Trixie to recruit the Diamond Dogs. For Gilda, I found her while I was in Cloudsdale." The mysterious figure chuckled evilly. "I recruited Flim and Flam during one of their inventions gone wrong and I found Trixie working at a rock farm. I also recruited General Shield Strike while breaking him out of prison after he committed a mass murder. He could not attend our meeting because he is currently planning our strategy with his soldiers."

"Exactly." Trixie nodded. "So, how are we going to do this?" Flim asked the mysterious figure.

"Simple, I help you get rid of your pains while you help me get rid of my pain." The mysterious figure answered.

"I still remember when Twilight embarrassed me with that Ursa Minor…" Trixie muttered. "And when everypony hated the cider my brother and I made!" Flam exclaimed angrily.

"Well, you cannot let your enemies defeat you like that." The mysterious figure said. "I would've gift wrapped those fools for all of you and you couldn't even dispose of them."

"You know, it wasn't like the ponies were alone, Loki." Rover stated. "Yeah, what are we supposed to do? Kill the princesses?" Spot asked.

However, Loki's serious expression turned into a sinister smile and he spoke the following words. "Precisely…" He hissed.

Then, without warning, Loki was jumping from column to column and left to right until he landed and the members of his army yelped and scampered out of his way.

Though, as Loki landed with grace, he began calmly walking through a vent of green smoke from the ground; then, on the opposite side of him, a second vent of green smoke shot out, but Loki continued walking in a calm pace. Then, both sides began shooting out green smoke while he walked through them without being affected. Finally, another blast of green smoke blew right in front of Loki, but instead he passed right through it. And what was even more frightening was that he was singing in a dark and sinister voice.

Loki: I know that your powers of retention

He sang while his emerald green eyes scanned one spot to the next.

Are as wet as a warthog's backside

The scene showed Fido chewing on a bone and not noticing that Loki was circling him around him.

But thick as you are, pay attention!

Loki levitated the bone away and Fido got into a force salute with a determined expression.

My words are a matter of pride

He continued to circle the dog while still singing.

It's clear from your vacant expressions

Loki waved his hoof in front of Fido's face and left.

The lights are not all on upstairs

When he was done, Fido smiled in a dumb way.

But we're talking kings and successions

Oblivious to Loki, Flim and Flam were behind him while snickering at what he was doing to Fido.

Even you can't be caught unawares!

He leaped at the two brothers, causing them to tumble over and land on two vents of steam. "WHOA!" Flim and Flam shouted as they were launched into the air.

So, prepare for the chance of a lifetime

Then, Loki continued to sing as he leaped from his spot to another ledge while Flim and Flam were screaming in the background during their fall.

Be prepared for sensational news

He snuck behind the ledge and was unseen until he said the 'sensational' part and reappeared, smirking at the viewers.

A shining new era is tiptoeing nearer

Loki strutted his way past Discord while Gilda noticed his act.

Gilda: And where do we feature?

She asked, wanting to know what would happen to the other members of the army.

Loki: Just listen to teacher

Then, he came near the griffin, playfully pinching her cheek as she yelped.

I know it sounds sordid

As Loki walked the other way, Gilda stared in confusion at him.

But you'll be rewarded

She then glared in his direction while rubbing her cheek.

When at last, I am given my dues

Then, he jumped off of his current spot and jumped onto another ledge where Spot was chewing on a bone. When he said 'dues', he put his hoof on his chest proudly

And injustice deliciously squared

Loki bucked Spot off the platform and into a pile of bones.

Be prepared!

He shouted out before glaring at the army below.

"Yes, be prepared! We'll be prepared! For what?" Fido asked. "For the deaths of the princesses!" Loki announced.

"Why? Are they sick?" Rover questioned.

"No, fool, we are going to kill them. And Twilight Sparkle and her friends and my brother too." Loki smirked.

"I'm only doing it to pay Twilight back for the Ursa Minor incident." Trixie shrugged. "I'm gonna destroy Rainbow Crash!" Gilda declared happily.

"A little payment to Applejack and her family will be the sweetest payback, wouldn't it, brother?" Flim asked. "I agree!" Flam nodded with an excited expression.

"I guess that leaves me with Fluttershy since the Diamond Dogs decide to get their payback on Rarity." Discord muttered.

"Great idea! Who needs a king?" Spot asked. "No king! No king! La-la-la-la-la-la!" The Diamond Dogs sang.

"IDIOTS! THERE WILL BE A KING!" Loki snapped down in a vicious tone. "But you said—"Flam protested, but was cut off by Loki.

"I WILL BE KING!" Loki interrupted. "Stick with me…and you shall rule Equestria for all eternity!" A light shone down on the area mysteriously behind him while his identity remained hidden.

"Yay! Alright! Long live the king!" The Diamond Dogs cheered as the light shone on some dark areas, revealing Diamond Dog soldiers.

"Long live the king! Long live the king!" The soldiers chanted. Suddenly, yellow flames covered the screen when they started singing.

Diamond Dog Soldiers: King, king, king, king, king, king!

The flames lit up a bit to show the Diamond Dog Soldiers marching like the Third Reich while many turned their heads to pay attention to Loki.

It's great that we'll soon be connected

With a king who'll be all time adored

Loki smirked evilly as he watched the marching from a platform above.

Loki: Of course, quid pro quo, you're expected

He held up one hoof with a sly evil smile on his face.

To take certain duties on board

Loki moved his hoof across his neck slowly, hiding an evil smirk to his army.

The future is littered with prizes

He continued to watch the marching soldiers who stared at him as if he were a dictator.

And though I'm the main addressee

Loki put his hoof on his chest as if he were declaring something important to his army.

The point that I must emphasize is

He jumped off of the platform and approached a Diamond Dog soldier without warning that was freaked out by the villain's presence. Suddenly, the ground began to crack and emit red smoke under Loki's pressure.

You won't get a sniff without me!

Loki raised his voice, moving to close to the frightened soldier while still in the shadows until he fell through the crack. "AHHHHH!" The Diamond Dog soldier screamed.

So prepare for the coup of the century

The columns in the fortress were soon rising as he jumped from one spot to another while declaring what they should be prepared for.

Be prepared for the murkiest scam

Loki jumped onto another column while the Diamond Dog soldiers were on their own columns.

Background Chorus: Oooh la, la, la!

A trio of soldiers was moving to the music at the last part while being lifted up by their own columns.

Loki: Meticulous planning

He turned to his right.

Background Chorus: We'll have food!

Some Diamond Dog soldiers were dancing while singing the chorus.

Loki: Tenacity spanning

Loki swiped his right hoof in a sly style.

Background Chorus: Lots of food!

Behind Loki's rising column, more soldiers were dancing in their own way.

Loki: Decades of denial

He raised his left hoof while his column rose.

Background Chorus: We repeat!

The Diamond Dog soldiers were unseen as the scene focused on Loki on his column.

Loki: Is simply why I'll

He declared while posing on the top of the column.

Background Chorus: Endless meat!

The Diamond Dog soldiers were last seen on their columns while they're singing.

Loki: Be king, undisputed

He lowered his head.

Respected, saluted

Loki stared from left to right.

And seen for the wonder I am

He proudly put his hoof on his chest. As soon as that moment ended, the scene changes to the shadows of two skeletons of ponies.

Yes, my magic and ambitions are bared

The camera moved down to reveal Discord swaying the skeletons around to the music before he smashed them against the wall.

Be prepared!

Loki grinned evilly as he looked down at his army. Now, a lot of the Diamond Dog soldiers were hopping from column to column while dancing to the music.

Then, from the smoke of some erupting vents, Trixie, Gilda, Flim, Flam, Discord, and the Diamond Dogs stuck their heads out of the smoke while singing with Loki and the others.

All: Yes, our teeth and ambitions are bared

The members of the army smirked.

Be prepared!

The scene then showed Loki, his army, and the Diamond Dog soldiers standing on their columns in front of the moon while the main villain was on his column in the middle.

"BWAHAHAHAHAHAHAHAHAHA!" They cackled as the song ended.

This sound would spell trouble if this plot was kept secretly. But afar, watching them, was Princess Luna. She was guarding the night when she overheard the whole commotion and listened from above.

"This must spell trouble…I have to tell my sister right away!" Luna mumbled to herself, flying to Canterlot Castle.

Back at the castle, Celestia was looking through her telescope on the balcony, waiting for Luna to come back from her night patrol. All of a sudden, Luna came flying in with a concerned expression on her face.

"What troubles you, sister?" Celestia asked as her sister landed on the balcony. "I'm afraid there is an evil plot brewing." Luna sighed, staring at the columns rising in the distance.

"You mean…the God of Lies and Mischief will attack us?" Celestia gasped.

"Yes, take a look!" Luna shouted as she gazed through the telescope where the columns were. "There were strange sounds from afar…that sounded like distant singing."

"Gather the guards and inform them of a possible invasion of Equestria! After that, meet me back here and we'll discuss what to tell the citizens of Ponyville about the invasion and send a letter to Shining Armor to tell him to follow you there!" Celestia commanded to her sister. "Yes, sister!" Luna nodded before running to tell every guard in the castle.

"We'll need your help fast, Twilight…" Celestia muttered.
