Demon Holocaust (R-Rated Cut)

PROLOGUE

In the land of the unicorns, in a small village, everything was hell. Body parts were everywhere, and so much blood was all over the street, it was nearly impossible for any pony to move very far without getting the substance on their hooves. Massive clouds of black smoke rose into the sky, blocking out the sun and turning daytime into night.

The clouds of smoke were rising from burning buildings in the small town that a group of unicorns were desperately trying to save. Dirtied, tired, and covered with the blood of friends and colleagues, they fought on, fought against the Corrupted Ponies which were slowly driving them towards the town square.

The Corrupted used to be normal ponies, both Earth, Pegasi, and Unicorn, but they were now gone, all trace of personality wiped, complete with glowing yellow eyes, and merciless. The unicorns fought bravely, but the Corrupted had strength in numbers, and no matter how many of them the unicorns took out, more were behind them. The unicorns themselves were taking heavy losses, mostly from Corrupted unicorns that had once been friends.

Leading the attack against the town was a pony named Nightshade. Nightshade didn't used to be like this. He had been just another simple unicorn, trying to find his way in life as all unicorns did. That was before he had been taken over by a demon.

The demon was old, impossibly old, born from hate and darkness, and had been trapped in the ground for a long time, until recently, a search team had accidentally unleashed the monstrosity upon the world. Nightshade had been the first unicorn it had found, and the unlucky colt had been taken over by the demon.

Over a matter of weeks, the now-possessed Nightshade had used his new powers to Corrupt ponies, make them follow his command, and he had done this not only with many unicorns, but Earth and Pegasi as well. Soon, with an army big enough, he had spent the last few weeks attacking the land of the unicorns. Town after town, they all fell, leaving nothing but bodies behind, as the survivors were all Corrupted and forced to join Nightshade's army.

This town seemed no different, Nightshade thought as his army advanced, with him at the front lines. It seemed it was going to be the usual routine, kill the defenders, rape the mares and foals, Corrupt or kill the survivors of the battle.

As Nightshade and the Corrupted advanced through the carnage, several bolts of energy hit him. The first few didn't penetrate his coat, the fourth one was dead-on though, and it tore part of his face off in a messy spray of blood. The wound quickly healed itself, and Nightshade laughed.

By now, the unicorns had retreated almost all the way to the town square, while Nightshade's army set fire to the buildings as they passed them to drive out the hiding unicorns.

As the Corrupted began to surround the defenders of the town in the square, the fight quickly turned into a massacre. With nowhere for the defenders to run, the Corrupted attacked them with everything they had, mowing them down as they desperately tried to protect themselves.

Just as victory seemed imminent for Nightshade, a unicorn- a mare- suddenly appeared at the edge of the town square. At first, Nightshade didn't notice, but he then looked up from the battle and saw the mare heading right for him, seemly unconcerned of the stray energy bolts that were flying everywhere.

Nightshade grinned and turned to face the seemingly defenseless mare, just as her horn glowed and six colored crystals rose up from her sides. This, surprisingly, seemed to grab the rest of the ponies' attention, and they all stopped fighting, Corrupted and defenders alike, as they watched the mare trot up near Nightshade.

About fifteen feet away from Nightshade, the mare stopped and spoke.

"I have been watching you for awhile," the mare said. "I have seen what you have done. I know you want to rule this land. But I'm afraid your rule is at an end."

With those words, the crystals floated above the mare's head, joined together, and began to glow brightly.

Nightshade stepped back and gathered energy in his horn, suddenly afraid. He didn't know what those crystals were but he instinctively knew that if they fired, it would be the end for him.

"NO!" he shouted, and fired, right as dazzling rainbow light burst from the crystals. The two streams of energy hit each other in midair, but Nightshade was already being beaten, his energy being forced back. Right before the rainbow energy touched his horn, he gave a final scream of rage, and then suddenly, the demon was forced right out of his body, ripped from the unicorn's soul, and the demon, now little more but a puff of smoke, super weak, sank right down into the ground, straight to the farthest depths of Tartarus.

The rainbow energy suddenly arched out from Nightshade's head, and began going into all of the Corrupted, driving the yellow out of their eyes, and then, it was all over. Hundreds and hundreds of once-Corrupted ponies, along with Nightshade himself, slumped to the ground, unconscious, as the few remaining defenders watched in disbelief. It was hard to believe- but the nightmare was finally over. The demon was gone, and the land of the unicorns was saved.

(Apx. 3,000 years later, present-day Equestria)

It had been nearly three thousand years since the demon had been banished to Tartarus. But it has finally escaped. It had hid in the depths of the hell itself until even the mighty guard dog Cerberus had forgotten about it. After that, it was easier to escape, but still hellishly difficult, as it had to be careful and not alert the guards of its presence. But it had succeeded. And now that it was out, it was mad. It had been evil to begin with, born out of hate and darkness, but after being banished for three thousand years, its fury was beyond imagination and it was more evil than ever. It was weak, however, no more than a puff of smoke floating on the wind, but after so long trapped in Tartarus, that was to be expected. What the demon needed was a pony to possess, possess once again, then the fun would begin.

Three thousand years ago, the demon had possessed a unicorn, and using that unicorn, it had killed thousands of ponies. It was only stopped by those crystals. Those strange crystals that had somehow torn him from the unicorn he was possessing, the crystals that had drained his power and banished him for so long. He knew one of the first things he would have to do would be to find out if those crystals were still around, and if they were, not let any pony possess them.

This land is mine. Kill anyone who stands up to me. I shall become the new leader. No one will stop me this time...

The wind blew the demon, the tiny puff of smoke, over a large forest and over a road, high in the bright blue cloudless sky. Down below walked a male unicorn- just what the demon needed to begin its slaughter. Fighting against the breeze, the demon forced its way down, towards the unicorn, and it hit the unicorn's body, and-

Falling Streak was just an ordinary unicorn living in Ponyville who never should have had a big impact on history. He had a sky-blue coat, dark purple eyes, and his mane was even lighter blue than his coat was with streaks of white in it. His cutie mark was a paintbrush; he was an expert at art. Although not exactly well-known, his work had been displayed across various art shows around Equestria, a few of these shows taking place in Canterlot itself.

This one particular morning, Falling Streak got out of bed as usual, and went downstairs but skipped breakfast. He got around quietly as to not wake his daughter or wife, who were still asleep. He wanted to get to a nearby village where his work was; he would just have breakfast there. He set off as soon as the sun rose high enough in the cloudless sky, walking because it was such a beautiful day out. He started on his usual path, trotting along the road, humming to himself. As he walked along, he passed several other ponies out for morning walks, and greeted them warmly.

As Falling Streak was walking along, on the road next to the Everfree forest, minding his own business, he suddenly felt something very cold sink into his back. He gasped as the freezing cold spread throughout his body. His heart stopped, and he fell to the ground, convulsing uncontrollably, gasping for breath. His vision instantly began growing gray, and he felt his blood run ice-cold. He felt the thing that had been absorbed through his back spread throughout his body. His very last, absurd thought was, maybe I should have taken my carriage...

The thing that was Falling Streak and at the same time wasn't investigated its own brain. Ohh, this was interesting. The land was now called Equestria. This pony, Falling Streak, was an artist. Lived in a town called Ponyville. Wife and a young teenage daughter. Enjoyed going to a place called Sugarcube Corner occasionally for a treat or two. All of Falling Streak's memories now belonged to the demon, including the directions to get back to Ponyville. Falling Streak laughed to himself, he wasn't going to work today, there was some killing to get to.

The demon turned Falling Streak's body around and made it start to walk back towards the place called Ponyville. The pony had already walked about a fourth of a mile, so he had to walk a bit of a ways to get back.

Walking back to Ponyville, Falling Streak passed several ponies. Several of these ponies smiled at him. The demon just glared at them all, leaving them confused as to what they had done wrong.

After a few minutes, the demon entered Ponyville. A lot had changed in this land, Equestria, over the last three thousand years, but he was expecting it, Falling Streak's memory told him everything he needed to know. Everypony looked happy, and one of them stood out in particular, a pink pony (Pinkie Pie, his memory told him) who was bouncing around cheerfully, giving greetings to all she passed.

The demon looked around town, wondering where to begin the slaughter. It thought of Sugarcube Corner. Falling Streak's memory told the demon that four ponies lived and worked there; the Cakes and their two babies. The demon smiled. Perfect.

Approaching Sugarcube Corner, the demon saw that the shop didn't open until a little later in the morning. Falling Streak's mouth turned upwards into a smile, this would make things so much easier.

The demon went around to the back of Sugarcube Corner and used Falling Streak's magic to open the window without a sound. The demon climbed in, and as it did, it felt the final stage of possession happen. The unicorn's body finally absorbed the rest of the demon. The demon was now no longer sharing Falling Streak's body, Falling Streak was the demon now. And he felt powerful, ready to kill.

***

Mr. Cake was upstairs, changing the baby's diapers that morning, and never heard the window open downstairs. All he was doing was concentrating on getting the smelly job done, and finally, done with that, he threw the two soiled diapers away and left the babies' room after each giving them a kiss on their foreheads.

Done with that, Mr. Cake walked downstairs- and was instantly blasted into the wall with a bolt of energy. The back of his head slammed into the wall with incredible force, leaving a bloody smear there. Gasping in pain and surprise, the pony tried to stand up, but his vision was already going gray and blurry. His attacker stepped into view behind the counter, took careful aim, and fired off another bolt at the helpless Mr. Cake. There was a flare of agony as the left side of Mr. Cake's face blew apart in a spray of blood which sprayed onto the walls and floor, and Mr. Cake slumped to the ground again, in too much pain to get up or make a noise, a waterfall of blood running down from the ruined side of his face and onto the floor.

"Let's make sure you stay there, now!" Falling Streak said with a laugh, and used his magic again. A knife floated into the air and flew at Mr. Cake, going through his hoof with little resistance and pinning it to the wall. As blood began to leak out from the hoof pinned to the wall, Falling Streak used his magic and brought another knife into his own hoof and turned to go upstairs.

Falling Streak walked into the Cake's bedroom where Mrs. Cake was standing making the bed, and as she turned, Falling Streak casually used his magic and sent his knife slashing across her face diagonally, the blade cutting through skin and muscle. Mrs. Cake screamed in pain as bright red blood fell, running down her face and falling to the floor and the bed. Falling Streak jumped on top of the wounded pony and clamped his jaws around Mrs. Cake's right ear, and with a tremendous yank, tore it, causing more blood to spatter. She screamed again, and Falling Streak used his magic to bring the blade straight down into Mrs. Cake's mouth, slicing into her cheek.

As Mrs. Cake began to choke on her own blood from her slashed mouth, Falling Streak felt his member harden. This was going to be fun, the most fun he'd had in a very long time.

Falling Streak grabbed the knife in his hoof and brought it down into Mrs. Cake's eye. He wiggled the knife, and blood began to come out of the socket. Mrs. Cake tried to scream in agony, but she just inhaled more of her own blood and began to cough more and her own blood sprayed back out of her mouth in the form of a reddish mist.

"You want this, don't you!" Falling Streak said with a glint in his eyes. "You want it!"

Mrs. Cake struggled weakly, but Falling Streak moved fast, lined up with Mrs. Cake's crotch, and shoved his stiff member into her, laughing.

Mrs. Cake's face was now completely covered with eye fluids and blood, and still, Falling Streak stayed on her. With one final thrust and grunt, Falling Streak came inside of Mrs. Cake, right as he shoved the knife the rest of the way into her head. Mrs. Cake convulsed violently one last time in a death spasm, and Falling Streak wrenched the knife out of her head, pulled himself out of the corpse's body, and licked the blade of the knife clean.

Done with that, Falling Streak used the knife and brought it down into the corpse's stomach as deep as it would go, then made cut straight across. He then grabbed the wound in his hooves and tore it open, revealing Mrs. Cake's insides. Done with that, Falling Streak reached in, and began tearing out her intestines and internal organs. He threw them carelessly behind him, spattering blood all over the floor. Falling Streak thought of something else. He was an artist- why not use his talent? He used his hooves and began to paint the bedroom walls with Mrs. Cake's blood, laughing crazily as he did so.

There was suddenly the sound of crying outside of the room. Falling Streak turned towards the door. The babies. This was going to be fun. He hadn't slaughtered babies for three thousand years. He ran into the hall and listened, and heard the sound of the babies in a bedroom on the other side of the hall, near the stairs.

Falling Streak walked into the bedroom and saw the babies lying in their cribs. He used his magic, lifting Pound Cake and Pumpkin Cake out of their cribs and slamming them to the floor, very hard, and both babies began to scream in pain.

"Oh, shut the fuck up!" Falling Streak yelled, walking over to them. He looked at both babies wailing in pain, and he decided to start with the girl.

Without hesitation, Falling Streak picked up Pumpkin Cake, used the knife he had used to kill Mrs. Cake, and with one quick motion, sliced and flung the body out of sight behind the crib. Pound Cake watched this the whole time through tear-filled eyes, and although he didn't know what was happening, he began to scream louder. That was when Falling Streak turned to him. He used his magic to pick up Pound Cake, and threw him up into the ceiling, and the baby fell to the floor in a lifeless heap.

Using his magic, Falling Streak carried the baby out into the hall, and threw him down the stairs with brutal force, and the dead baby landed downstairs near Mr. Cake, who gave a groan as he saw his son.

Falling Streak arrived at the foot of the stairs several moments later, holding his knife. He stepped in front of Mr. Cake who was still pinned to the wall by his hoof. Mr. Cake looked up in fear, as Falling Streak brought the knife down, slashing across his one good eye in a quick motion. Blood and fluid began to run down the intact side of Mr. Cake's face, and, blinded, he screamed.

"Shut up!" Falling Streak hissed. "Someone outside will hear you!"

Falling Streak kicked Mr. Cake in the face as hard as he could, right in the mouth. Blood and teeth fell out of Mr. Cake's mouth, and Falling Streak kicked him in the ribs over and over until he heard several crack.

"I'm done with you!" Falling Streak shouted, picked up a knife, and slit Mr. Cake's throat. Mr. Cake began choking, and Falling Streak reached down with his hooves and tore the wound open, enjoying the wet sound of tearing muscle. The inside of Mr. Cake's throat was visible and shreds of skin and muscle hung down. Falling Streak lowered his head, listening to the pony gag weakly as he stared at him. Mr. Cake struggled a little more, choking on blood, then he was still.

Falling Streak, covered in blood and body fluids, grinned. Feeling more happy than he ever had, he went to the back of Sugarcube Corner to escape from the back window, and continue his slaughter.
