The Canterlot Castle was engulfed in flames, but the flames were neither lethal nor were they burning the castle. Within the throne room, Slash sat upon Celestia’s throne and Twilight sat upon Luna’s throne. The two sisters were tied up in chains before them. He looked upon his paws where images of his enemies were imprinted. “Twilight, my dear, the age of terror commences today. With your friends as my faithful monsters to dominate this kingdom, you’ll have no choice but to obey my will. I mean, it is for your good after all.” Slash grinned.
“You won’t get away with this, Slash!” Twilight said while she glared. “We will stop you!”
“How will you be able to stop me if you have insufficient resources to do so?” taunted Slash. “Oh and by the way, your two precious princesses look quite beautiful. Perhaps they will do well as my queens also.”
“GET AWAY FROM TWILIGHT, FIEND!! You are destroying Equestria!!” defied Luna. She tried to blast off the chains from her but they were magic-proof.
“Did I forget to mention that I have bedded hundreds of princesses and queens of many species in my time? I even mated a changeling queen when I was younger. So none of you beauties will be any different from what I have specifically planned for you.” Slash said.
“You are a disgusting vile creature! Why are you doing all this? What is your objective here?!” Celestia demanded. Slash then dropped his smug look and scowled at Celestia.
“To gain the power what should have been rightfully mine long ago! With this powerful artifact, the Friendly Plague, I can turn any creature into a monster; combining that with the love and trust of friendship, they will be my slaves for all eternity!” he boasted.
“That's why you manipulated us to be your friends?!” Twilight cried. “So everything you told us about yourself being a lost abused cub enslaved to Grogar was a lie?! How can you betray us like that?! This isn’t right!!”
“Bravo, Twilight Sparkle, you’ve figured it out! Hahahahaha!!” Slash mocked, waving his arms. This made Twilight even more angry. “Now enough talk, my love. Come give me a kiss.” As he leaned to her, Twilight smacked him in the face and tried to move away from him. Unfortunately, her hooves were chained to the throne, and her horn was sealed shut by his magic.
“Ahhh, you like to play rough, huh? Very well. Even cats need to play rough. I know it’ll teach you a lesson.” Slash spoke. He extended his claws and readied himself to scratch her. But a sudden poof of magic interrupted him, causing him to turn around to behold the intruder. Right before him stood Grogar, his hated brother.
“BROTHER?!? HOW IS THIS POSSIBLE?! GUSTY WAS SUPPOSED TO DEAL WITH YOU!!” Slash roared in shock and wrath.
“Ha! We both have settled our differences though it was inconvenient. But now I’m here to put an end to your terror once and for all!!” Grogar declared. His presence shocked all three alicorns present.
“Grogar?! How are you here?! I thought you were a myth!!” Twilight exclaimed with a fearful expression.
“Twilight Sparkle, it’s quite an honor to meet you in the flesh. And fear not, my traitorous brother and all of his heinous crimes will become a myth from this day forward.” Grogar replied, glaring at the panther. Slash growled in rage and fear.
“It’s too late, Grogar! I’ve already won the battle! I’m now the new and only Father of monsters to rule this kingdom! Now, I am the most powerful being in Equestria!” Slash arrogantly gloated. Grogar then ignited his horns, ready to fight.
“You cannot take the love and kindness from these ponies and brainwash them to serve you. That isn’t fair for them!” Grogar reprimanded. This threw Slash in a rage.
“FAIR?! I’ll tell you what’s not fair! Spending a lifetime as a second-rate, unloved, and uncared child while you get all the attention and love from mother! Well, my patience has finally paid off, and no hand-me-down self-righteous ram is going to mess it up for me now!!” Slash shouted in fury. He raised his paws and generated clones of Grogar and his legion, surrounding him. “Clones, DESTROY HIM!”
They all shot their magic beams at Grogar. He jumped in the air which made all the shots strike at each clone standing. Some of them exploded on the spot while the others recovered quickly and refocused their attack on the ram. Grogar raised his hooves and sprouted magical whips. He lashed at every clone that attacked him. He dodged, kicked, punched, and shielded.
Slash was enraged to see him wiping the floor with them easily. “Fine! I’ll kill him myself!!” Slash yelled. He roared out loud and lunged at the ex-villain. He tackled him on the floor while scratching wildly at him. Grogar shot at his back to get him off of him. Slash recovered from the blast and shot several bolts at him. Grogar ran across the room to avoid being shot while he returned fire with his magic. One of Slash’s bolts collided with Grogar’s blast and exploded, blinding everyone in the room.
After the dust settled, Slash opened his eyes and didn’t see Grogar before him. It wasn’t until huge curved horns rammed into him from behind him. He skidded across the room until he hit the left wall. Slash got up and unsheathed his magical spears again and threw them at his rival. Grogar seized them through telekinesis and crushed them by stomping on the ground with force. Then he generated magical daggers from his hooves and aimed them at Slash. Once he threw them, Slash caught them by paw and ate them all.
Slash lunged again at Grogar while the latter did likewise. With curved horns and sharp claws clashing together, both brothers struggled for dominance. “You are a weakling, Grogar! The Friendly Plague has made me more strong and powerful than you ever were! So now, you will bow to me!” Slash taunted while grunting.
“Fool! That artifact will kill us all! If it contains too much power and magic from other creatures, it will destroy the whole world! Look! It is glowing brighter by the second. Stop this madness now!!” Grogar pleaded. Slash looked down and saw the artifact glowing brighter than before. Wickedly smiling, he bit Grogar’s muzzle, scratched his cheek, and kicked him on the stomach. Grogar fell down on the floor with many bruises, including scratch marks.
“FINALLY!! Finally, I get to kill you for good! Look at everybody’s favorite villain now! You’re just a stupid, pathetic excuse of a brother! You’ve been number one for too long, Grogar! Now, your time is up! But don’t worry...this artifact will wipe clean all that unpleasant morality in this land.” Slash spoke before he readied himself for the kill.
Suddenly, he was blasted to the right wall of the throne room. Surprised and puzzled, he turned to see Celestia, Luna, Gusty, and Discord standing together. “Nice shot, Gusty! Looks like somepony’s target practice has improved.” Discord remarked, smirking. He snapped his fingers which made Slash’s magic seal and chains on Twilight disappear. Twilight ran to them and hugged Discord in gratitude.
“You see, old buddy? I told you that we need to work together.” Gusty reproved. Grogar growled in defeat and annoyance.
“I was able to hold my own against him! But there’s no time to argue! The Friendly Plague is about to detonate in the next couple minutes! It must be destroyed!” Grogar sternly warned.
“How? Slash is too powerful! How can we get pass him to get it?” Twilight asked. Grogar looked behind him and saw Slash quickly recovering. He then saw his legion and Gusty’s friends burst through the doors and joining them. He then got an idea.
“It’s just like how I’ve been emphasizing to my villains in my lair. We need to work together!! Though we may be opposite forces to each other, by being united in our common goal, we will emerge victorious! Concentrate your attack on Slash!” Grogar commanded them. Nodding in agreement, the heroes and villains gathered around Slash and unleashed their attack on him. Slash did everything in his skill and power to dodge all their magic blasts and attacks; however, he did suffer a number of hits and shots.
He kicked away Groundbreak and Tirek who tried to hold him down with their feet. He shot several bolts at Sharpbeak and Chrysalis but they managed to fly out of the way of the assaults. Celestia and Luna combined their magic and blasted him on his back, causing him to stagger on the floor. While he was distracted, Cozy and Twilight took him via telekinesis and kept him high in the air. “Let me go! You dare side with that worthless degenerate!! I am your true master!!” Slash defied while swinging wildly to set himself free. His effort was in vain.
“Joypath, now!” Grogar ordered. The hyena swung her chain right at the Friendly Plague and snatched it away from Slash. She gave the artifact to Grogar and Gusty.
“Ready, old friend?” Gusty asked.
“More than ready. Now!” Grogar said. Both of them combined their magic on the device. The surge of magic started to fully overwhelm the Friendly Plague to the point where it cracked and crumbled to pieces in a huge white explosion. All the heroes and villains were protected in Twilight’s bubble shield. The explosion took out half of the castle. All the love and friendship the artifact drained were then set free and returned back to the beasts who were still lying on the ground. Once they returned, all of them returned back to normal ponies.
Spike, Starlight, Applejack, Rainbow Dash, Rarity, and Pinkie Pie woke up and saw their surroundings. “What...what happened? Where are we?” Spike asked.
“Wait a second...ah remember!! That backstabbing animal tricked us to be his friends! He turned us into monsters!” Applejack said, glaring at the sky. Discord appeared right in front of them.
“Now that you've mentioned it, you might want to head right back to Ponyville. That is where karma will be served for dinner!” he said, wearing his chef garment and hat. He snapped his fingers that caused all the smoke, dark clouds, burning fires, and debris to all disappear from Ponyville. All the houses were quickly rebuilt and all the corpses were sent to their burials in the cemeteries.
Twilight and Cozy then dropped Slash on the ground. Tirek then gave a death glare on the defeated panther. “This is for my uncle and for my family!!” he shouted. He opened his mouth and drained Slash all of his magic. Slash yelled in pain as all of his magic was taken from him. Grogar and Gusty looked upon him with scorn.
“I believe that a proper punishment would be more appropriate for you, Slash. Being sent to Tartarus is too merciful in my book.” Grogar judged. “Wouldn’t you agree, my friend?”
“Absolutely. In fact, Discord has a nice surprise for you in Ponyville.” Gusty added, smirking. She and Grogar blasted Slash all the way to Ponyville. There, he landed hard in the middle of town.
Once he got up, he saw everypony and every creature surrounding him and death glaring at him. He saw the Mane 5, Spike, the CMCs, Gabby, the Young 6, Big Mag, Sugar Belle, Ember, Lyra, Bon Bon, Cadence, Shining Armor, Flurry Heart, the griffons, Thorax, Pharynx, Grandpa Gruff, the changelings, the yaks, and everyone else. Suddenly, Twilight, the Royal Sisters, Discord, Grogar, Gusty, Sombra, Chrysalis, Tirek, Cozy Glow, Groundbreak Tusk, Sharpbeak, and Joypath appeared in a white flash and rejoined them.
“Uhhhh...hahaha...hello there—fr-friends! It’s...good to see you all!” Slash uttered fearfully.
“You ain’t no friend to us no more! Not after what ya did!” Applejack snapped.
“Out of all the animals I’ve cared for, you are the WORST!!” Fluttershy added angrily.
“I guess you all know what this means!” Discord asked, snapping his fingers again. Javelins, knifes, nunchucks, and whips were given to everyone present except for the ancient beings. “Roasted cat coming right up on the MENU!!” Discord shouted, ringing his little bell.
Slash’s face went pale in fear and horror. He started fidgeting once he looked around and saw the ponies and creatures drawing nearer to him. Without warning, they stabbed him on every side of his body. He screamed in agony. The Mane 5 punched and kicked him repeatedly; Gabby and Terramar whipped him; the yaks kept stomping him on the ground, breaking all of his bones; the changelings stabbed his legs; the CMCs bit his arms and cut off his tail; Chrysalis sucked up his love; and finally, the dragons including Spike breathed fire on him, consuming all of his flesh. What was left of him were his broken bones.
