An Equestrian Nightmare

The wall of darkness continued it's advance on Celestia. She accepted her fate, knowing full well of Moon's enhanced power. She closed her eyes and waited.

BOOM

The wall of darkness dissipated in front of Celestia and Luna. Nightmare Moon was shocked.

"What?!" exclaimed Nightmare Moon. The remaining darkness gathered in front of Moon. It the molded itself into that of a tall man with long black hair. The man was wearing a dark trench coat and had black shoes. The man then looked up at Moon. Her expression changed in a heartbeat.

"Nightmare Moon." said the man. His voice was rather soft, like Fluttershy's, but much deeper in pitch. Two demon heads then broke through the man's coat. They originated around his shoulder blade area.

"No." said Moon.

"Yes." said the man. A black hole then formed behind Moon. She tried fighting it's powerful suction, but failed. She was dragged into the hole, screaming as she went. The hole then closed, leaving the man and the two princesses alone.

"Who are you?" asked Luna.

The man turned and looked at her, his eyes were glowing yellow with power "Your guardian angel." The man then disappeared, leaving some darkness behind when he teleported.

"Wow." said Celestia.

"He's kinda cute." said Luna. Celestia looked at her in disbelief.

"What?"

"Your unbelievable." said Celestia. She then went back outside to assist with the reconstruction of Canterlot.

Nightmare and Siegfried slashed upward toward the monsters, Inferno and Necrid dodged the attacks. Nightmare smacked Necrid with the flat of his sword, sending the green monster to the ground. Siegfried slashed at Inferno, causing some of Inferno's flame to fall off. Nightmare also slashed at Inferno, removing more of his flame. The two warriors then combined their power and simultaneously sliced Inferno, causing the flaming monster to scream and disappear.

Necrid got back up, the medallion on his chest turned green. He then ran up and sliced at Nightmare. Nightmare blocked the strike and kicked Necrid in the stomach, leaving the monster open for attack. Siegfried capitalized on the opportunity and stabbed Necrid's medallion. Soul Calibur began to drain Necrid's power into itself. Necrid dropped onto his knees, weakly grasping at the sword in his chest. Necrid noticed that his skin was reverting back to it's normal self, slowly losing the green, scaly appearance. Necrid then looked up at Siegfried. The sun gleamed off his armor, giving him a somewhat angelic appearance. Necrid's body then began to vaporize.

"Thank you." whispered the now human Necrid. Soul Calibur dropped to the ground, it glowed a bright blue from it's new power. Siegfried picked up Soul Calibur and sheathed it.

Nightmare walked up to Siegfried "Good teamwork."

"Yeah, thanks." said Siegfried. The two warriors walked through town, stopping by the train station. Twilight and the other ponies gathered there to avoid the fight.

"Is it over?" asked Twilight.

"Yes." answered Siegfried.

Nightmare sensed something was wrong. "No." Siegfried and Twilight looked at him. "It's only just begun." Behind Nightmare, Inferno's sword began to levitate. The three ponies watched as the sword caught fire. Inferno then appeared by the sword and grasped it. Siegfried was about to attack him, but Nightmare stopped him.

"This is my battle." said Nightmare.

Siegfried looked at Nightmare "Good luck." Nightmare slowly trotted up to Inferno. He stopped a good distance away from him. The two looked at each other with intent. Inferno was first to attack, running up to Nightmare. Inferno raised his sword above his head and brought it down. Nightmare blocked the attack with the front of his sword. He then slashed at Inferno's body, removing some of his flame and causing the monster to scream. Inferno lashed out at Nightmare, sending the Azure Knight back. Nightmare readied his sword, for he had a plan. Inferno ran toward Nightmare, sword held high.

Nightmare summoned all his strength "Let darkness..." Soul Edge was now on fire "...take you!" Nightmare slashed Inferno at an upward angle, sending him flying into the sky. Inferno hit the ground with a loud thud. Nightmare walked up to Inferno and kicked his sword away. He then raised Soul Edge into the sky and brought it down on Inferno. The sword went right through him. Nightmare then raised his claw. A bolt of lighting hit Nightmare and arced into Soul Edge. Inferno's power flowed into Soul Edge. The evil sword was glowing a bright red, wisps of energy surrounding it. Nightmare walked back up to Siegfried and Twilight.

"Now it's over." said Nightmare.

"How...did you do that?" asked Twilight.

"Trade secret." answered Nightmare.

"So what now?" asked Siegfried.

"I don't know. With Inferno's power in Soul Edge, the fragments are cannon fodder. They serve no purpose anymore." explained Nightmare.

"Alright, we better report back to Celestia." said Twilight. She looked at Nightmare "She's gonna want to talk to you."

"This should be good." said Nightmare. He then teleported himself, Siegfried, and Twilight to Canterlot.

Celestia went back to helping the citizens of Canterlot. She saw Whirly and her subordinates helping the injured. Celestia walked through the town, observing all the damage, the loss of life, everything. She almost wanted to cry, but remembered who was the root cause of all this. Discord.

Discord, you better pray I don't get my hooves around your throat. thought Celestia. She stopped at the center of town, noticing the burn marks where the monster appeared. The spot began to glow.

"Get back!" yelled Celestia. The ponies hid in fear as to what other monstrosity could appear next. A ball of flame appeared before Celestia. She readied her magic. The flame then dissipated and revealed the forms of Nightmare, Siegfried, and Twilight.

Nightmare looked at Celestia "Princess."

"Was there call for that?" asked Celestia.

"To flashy?"

"Quite."

"Don't care."

"Anyway..." said Twilight, trying to avoid the awkward scene "We've got important information for you."

"Due tell." said Celestia.

"Nightmare and Siegfried are working together."

"I kinda noticed that due to the fact that they aren't killing each other right now."

The two warriors looked at Celestia "Hey, that is uncalled for."

Celestia waved it off "So now what?"

"We find Discord and kill him, plain and simple." said Nightmare.

Twilight looked at Nightmare "Are you always this blunt?"

"Subtlety isn't one of my strong suits." said Nightmare.

"Enough talk, let's go find Discord and end him." declared Siegfried.

"Alright, but first. Whirly!" called Celestia. Whirly appeared by Celestia in a nano second.

"Yes, your highness?" asked Whirly.

"You're going to help these three." Whirly looked at Twilight. She smiled when she saw Siegfried, but grimaced when she saw Nightmare. Nightmare noticed this.

Every time thought Nightmare

"I will help them to the best of my ability." said Whirly.

"Excellent." said Celestia "I heard of a disturbance in Stalliongrad, would you four go check it out?"

"Sure." agreed the four. Celestia then teleported the group to Stalliongrad. When the four arrived, they were met with a grizzly scene. The bodies of ponies were either strung up on the roofs, decapitated, or burned beyond recognition.

"Dear, Celestia." said Whirly "They were massacred."

Discord was busy going over today's events in his head.

So, I finally get Necrid and Inferno to work together, and they can't even defeat Nightmare and Siegfried. I'm running out of evil to help me. I got Stalliongrad out of the way, but Canterlot and Ponyville still stand.

He got out of his chair and teleported back to the cliff overlooking Canterlot.

"Got to do everything my damn self." said Discord. He was about to teleport to Canterlot, but was stopped by an unknown force. A ball of darkness enveloped Discord.

"What treachery is this?" asked Discord. Discord found himself in a dark place. There was not light anywhere. He heard footsteps.

"Who's out there?" asked Discord.

I thing you mean "what is out there" whispered a voice. A shiver traveled up Discord's spine.

"No, it can't be." said Discord. A flame then appeared in front of him. A figure then walked out of the flame, holding a glowing scythe.

"IMPOSSIBLE!" exclaimed Discord.

"You miss me?" asked a fully revived Abyss.
