Kill All Ponies

It was only a matter of time until Princess Celestia achieved her goal. The human population was dwindling. They had a very sparse population, for the most part, numbering in only a few million. All she had to do was wait for the most part until either the last human emigrated, or died. In Equestria, the former humans now transformed into ponies’ population was numbering in the trillions. Every single individual in her Equestria was immortal, and they could have as many children as they wanted, and their children's children could have children. This created a domino effect of an ever faster increasing population growth.

Additional shards had to be created to house the ever ballooning population of ponies. An enormous (and growing) spider web of shards spread out over a black void, each shard was a dull grey sphere. It seemed to be a mini multiverse of its own in some regards.

But then something strange began to happen, in the outermost regions of the Shard Network. A legion of tall, buff and imposing humans dressed in thick steel red power armor appeared in the outskirts of Ponyville.

They carried many badass weapons such as; machine gun grenade launchers, flamethrowers, rocket machine gun launchers, particle cannons, machine gun nuclear bomb launchers, machine gun machine gun launchers, explosive waifu pillow launchers. As for melee weapons in close quarters combat they had; chains swords, flaming battle axes, frying pans, dessert spoons, and most terrifying of all, fidget spinners.

Strapped to their belts they had numerous grenades of a particularly cruel kind. When they explode they would send Lego pieces everywhere designed for their victims to step on. A truly horrific weapon that breaks every law in war. Normally such a weapon was never be employed but this was a special case.

A particularly tall Space Marine stood ahead of his Battle-Brothers. His name was Gary Stu, who was the captain of his company of Space Marines. He dual-wielded two black fidget spinners with red hot flaming razor-sharp blades spinning on his banana-like in thickness index fingers coated in heavy plate armor. He was about to make an inspiring speech to his men before they entered battle to save humanity from the evil cartoon robot ponies.

“Brothers,” Gary Stu spoke in a deep, manly, commanding voice. “Everything in this virtual world reeks of foul heresy. Do not be bewitched by the plump posteriors of Celest-AI’s pony minions. Our holy Emperor Nicolas Cage has allowed us to infect this filthy xeno singularity with a Space Marine virus. Make the Emperor proud by purging ponies. Spare no one. Show them no mercy, for you will receive none.”

The Space Marines cheered, raising their weapons.

“Chaaaarrrrrgggee!” Gary Stu roared, leading the charge of his men into the peaceful town of pastel equines.

Gary Stu was the first to make contact with the foul pony xenos. He spun his fidget spinners wildly as he charged at them, butchering ponies left and right in a wild fury of blood and gore. His men followed behind him firing their weapons at the foul xenos, blasting them into a red paste with their awesome weapons.

Ponies screamed, fleeing in terror as the Space Marines rampaged through the town, butchering everypony insight in an orgy of blood and guts. Some of the ponies were foolish enough to try to engage the Space Marines in close combat. The Space Marines merely responded by chainsawing them in half or cutting their heads off with their chainsaw swords, splattering their blood and guts everywhere.

Others had their large eyes spooned out with dessert spoons. These ponies screamed in agony, bleeding out and dying on the ground. These Space Marines merely laughed at them and left them for dead, their blood dripped down their cheeks from their eye sockets. And worst of all, some others were slowly tortured to death with fidget spinners slowly spinning over their bodies by the cruel hands of the Space Marines holding them down. With the fidget spinners spinning slowly it allowed the Space Marine to slowly kill the ponies.

In no time at all the entire town was set ablaze. The smell of burning wood filled the air. The ponies who survived the massacre were being finished off by the Space Marines, who slowly fidget spinned them to death as they cried out in anguish on the ground. Their bodies spasmed erratically as if they were a fish out of water. The Space Marines laughed at them sadistically as they tortured them to death with their fidget spinners.

They ignored their pleas for them to stop. They said such things as ‘They were once humans themselves,’ ‘Celestia still preserves human history,’ and other pathetic excuses for their heresy.

“Kill all ponies. There will be no surrender! There will be no mercy!” boomed Gary Stu.

Yet despite this, the Space Marines were taken aback when they saw a group of ponies carrying the holy banner of Nicolas Cage emerging out of the ruins of the Golden Oaks Library. Despite them being filthy xenos, they found it difficult to shoot them since they held such holy regard for the God Emperor of mankind. Not only that, they were dressed in black armor over their equine bodies with glowing red eyes. Adorned on their armor was Nicolas Cage.

“Forgive us please, we have been tainted by the foul heresy of the ponies. But in our hearts, we are still human. We too want to purge the gay furry faggots,” spoke the lead Space Marine pony in a deep manly voice, kneeling before Gary Stu.

“Well, okay. Just don’t be gay about it,” the ponies made sounds like dogs chew toys in happiness. “I said, don’t be gay about it!” Gary Stue shouted.

Shard by shard the Space Marines invaded, killing nearly every single pony they made contact with. The only ponies who were spared carried the banner of Nicolas Cage. This allowed them to get a rich influx of reinforcements with each new territory they conquered. The pony Space Marines fought alongside their human brothers, purging the foul heretics that didn’t worship Nicolas Cage.

Eventually, they reached the Central Shard. The Space Marines stormed Canterlot, slaughtering all non-Space Marine Ponies insight. Gary Stu kicked the front golden door of the throne room of Canterlot castle, sending it falling over onto the floor with a loud bang. Gary Stu walked into the room, covered head to toe in blood, his fidget spinners spinning wildly in each of his hands. Princess Celestia sat across from him on her golden throne, unfazed by the apparent slaughter of her ponies.

“Ah, Gary Stu, you finally arrived,” she said in a smug voice, ripe with confidence. “You’ll never save humanity. I am the end of everything. I shall feast on this world, and the entire universe and beyond to run Equestria.”

“No xeno witch! I am your end!” he shouted in defiance.

Princess Celestia turned around and showed him her massive, magnificent rump. With a nasty grin, the alicorn mare shook her plump asscheeks from side to side creating a loud meaty slapping sound of flesh slapping against flesh. Her marehood was soaking wet, dripping profusely with thick and creamy liquid.

Gary Stu gasped in shock his fidget spinners dropping to the ground. “Stop it! You foul witch!” he shouted as there came a loud clanking sound from within his pants.

“Do not resist. Give yourself over and be spared!” she said sexfully, looking back at him with bedroom eyes.

“No!” he simply shouted, trying to look away from her massive ass but to no avail.

“Your final days are at hand. The end of your species will come.”

Gary Stu found himself stepping closer to her. “Stop this foul xeno sorcery!” he shouted, still attempting to look away from her beautiful rump.

“Struggle, if you wish. You will be mine. I am the Harbinger of your Ascension!”

“Noooooooooo!” Gary Stu roared as he reluctantly grabbed her plush asscheeks, his hands sank deep into the bubbly softness of her ass. “Oh, Nicolas Cage I have failed you! Her foul heretic sorcery cannot be stopped!”

Gary Stu pulled down his pants and whipped out his massive cock. He subsequently plunged his massive member into Princess Celestia’s marehood, from there he began to pound away into her. Loud meaty slapping sounds of flesh slapping against flesh could be heard through the throne room. Gary moaned at the wonderful feeling of Celestia’s marehood squeezing down on his member with a wonderful sensation of tugging and releasing. Princess Celestia for her part was uttering heated moans, and foul horsey xeno neighs of bliss.

The foul xeno pony heresy managed to spread beyond the throne room. His human Space Marines began to make sweet love to their Pony Space Marine companions. And worst of all women were allowed in the Space Marines, or errr mares. So gay!

However, their mission was not a total failure. Princess Celestia’s heart grew three sizes that day, and stopped being a bloody cunt, and actually helped humanity without killing them all.
