The Caribou have almost entirely conquered Equestria. The Princesses lay broken in Dainn's clutches, and the new world order is being established by his loyal followers. But something has left Tartarus in search of blood... it will bring their doom.

'They are Rage, brutal, and without mercy...

but you...

You will be worse.

Rip and Tear. Until it is Done.

\\\\\\//////

Dainn has won. The Princess of the Sun lays broken beneath his hooves, fit now only to clean his crotch. The Elements of Harmony are scattered and scared. Equestria has fallen, and the Caribou move to impose their society as the absolute law of the land.

Yet from their well of magic, something stirs.

The once dominating power they had has weakened significantly, and those that once channeled the mighty magics of the Caribou have gone insane, blabbering about the "end times". It was thought to be mere superstitions, the ravings of old lunatics.

That was until the Slayer had arrived.

Into the Fire

Rainbow Dash gagged and choked as the Caribou in front of her rammed his length into her mouth. Her eyes watered at the horrible scent that was flooding her muzzle and wanted to puke at the taste of his likely unwashed junk. In response, she bit down as hard as she could.

"Fuck!" he cried as he pulled out and backhanded the pegasus.

Rainbow crashed onto her side, coughing up and spitting out whatever was left in her mouth as she covered her chest with an arm.

"She bit me! That cunt dared to bite my rod!" he shouted angrily.

"Get bent and die!" Rainbow shouted back.

"Ah!"

Rainbow turned to see Cloudchaser being held down onto a bench as she was forcibly stripped of her shirt before the Caribou began to grope her painfully.

"Stop it! Please!" she cried in pain.

"Yeah, keep begging, slut! You'll grow to love it!"

Something collided with the side of Rainbow's face, sending her to the ground as a hand yanked her tail up.

"That's it, time to break in the n-"

The Caribou behind her wailed in pain as Rainbow bucked him straight in the daddy bags. He crumbled down onto his knees crying before Rainbow stood up, forgetting her nudity for the moment, and wrapped her hands around his neck as they went to the ground. She kept choking the life out of him, tears flowing from her own eyes as her mind failed to process the sudden shift in her world.

Just this morning, everything had been fine. She had a great night with her friends before having an even better night with Bulk and Flitter, and now these bastards were going around and burning the town and raping mares in the street while the stallions were all either comatose or screaming in pain. An evacuation had started some time ago, but she came back to make sure that there weren't any other mares trapped in town, and that was when they got the jump on her.

She just wanted to end this evil bastard in her grip. She just wanted to end this sudden invasion. She just wanted it all to end...

"Get that bitch!" a Caribou shouted.

Rainbow turned away from the blue-tinted face of the Caribou she was strangling to see a group of six Caribou charging at her with collars and electric batons.

'They're not gonna take me,' she thought, rage building in her heart. 'They're never going to take Ponyville!'

Before they could make it halfway to her, however, six flaring objects flew down from a nearby rooftop and lodged themselves into the faces of each Caribou. In an instant, the lights exploded, showering bits of brains and helmets over the immediate area. One Caribou pointed up from across the way and shouted.

"The Slayer!"

Something heavy thudded behind Rainbow Dash as she was yanked off of the Caribou. She had enough time to recover and watch as his head was crushed underneath a green metal boot. The pegasus looked up in horror at the armor-clad warrior as he hefted up some kind of smoking weapon.

\\\//////

Doom Guy pulled back the Charging handle for the Assault Rifle before examining the scene before him. There was another Flutter-something on the ground with no clothes looking up at him through a hairstyle that somehow made him want to rethink his thoughts on the collection of colors. Across the way were several once alive Caribou that he had properly dealt with, and now were being replaced by more than he bothered to count. It wouldn't matter. They'd stack up and die all the same.

"What the fuck are you?" the rainbow-Flutter-thing asked.

"Run," was all he said.

The Caribou charged at him with a war cry as Doom Guy leveled his weapon and opened fire. The .50 Caliber rounds tore through their flimsy leather armor and bare-chested assault, breaking through their bodies in a shower of blood as bits of their chests burst apart while they fell. Some of the luckier ones were shot straight through the head, ending their lives in the least painful way possible.

Doom Guy had enough of that.

Carelessly, he tossed the Rifle aside into some kind of Argent void (VEGA, yadda yadda, suit, blah blah hold more weapons, that's the only answer he cared about) and willed his Combat Shotgun forth from who-gives-a-shit. He pumped in a fresh shell and ran towards the remaining few Caribou.

A burst from his weapon tore the upper half of one off instantly. Doom Guy weaved around the body as he pumped the shotgun before firing at another's leg. As it was falling, he kicked it into the nearby fountain, breaking the stone and impaling the Caribou on the spire. Once more he pumped the shotgun and blasted the next unlucky fucker's right arm clean off. As he screamed in pain, Doom Guy repeated the action with the opposite arm before leaving him to bleed out.

"GGGGRRUUUURRRR!" something roared.

Doom Guy turned around and faced... one of the ugliest abominations that he's ever seen in his entire life (and that was an achievement all on its own). It had a face that looked similar to the ponies and Caribou, but its head made up at least a third of its body. It had uneven teeth, a shorter muzzle, scraggly hair and downward facing horns that overlaid its ears. On top of it was another Caribou, handling the reigns that ran through the cracks in its teeth.

And Doom Guy once thought that the Pinkies looked bad.

"Time to die, you heretic!" the rider said.

The beast charged towards the Doom Marine and lowered its head. In response, Doom Guy cast away his shotgun and cracked his neck as he dug his feet into the ground.

"Sir, I highly recommend that we move out of its way," VEGA informed. "By my calculations, this creature has the potential force to crush a UAC standard light-assault vehicle at its current velocity."

Ignoring the advice of the smartest thing on this planet, Doom Guy grinned as he held his arms open.

The Warbeast charged right into Doom Guy's arms and...

Was lifted straight off of the ground.

Using the momentum from it's charge, Doom Guy gripped its lower jaw tightly before allowing himself to fall back. He used his inhuman strength to slam the Warbeast onto the ground, crushing the rider. Doom Guy stood up and grabbed the edges of the Warbeast's head before twisting, snapping its head 160 degrees before it went limp.

"Astounding," VEGA commented. "However, there are more approaching from behind."

Sure enough, two more riders and Warbeasts were waiting for the Doom Marine.

"Kill it!" one said.

The second Warbeast charged towards him and Doom Guy chuckled as he decided to switch it up a bit. He jumped to the side and grabbed its horn, breaking it off as he hoisted himself onto the saddle. The rider gaped in shock before his face was introduced to an intimate relationship with Doom Guy's boot, their love for one another so intense that the Caribou's neck broke from sheer jealousy. Turning around atop the Warbeast, Doom Guy plunged the severed horn into its eye and punched it in deeper, the beast falling onto its stomach as it moaned in agony.

The Doom Marine hopped off of the dead creature and turned to face down the last Warbeast and rider, who were circle-strafing a good distance from him. Doom Guy spread out his arms in a gesture that spoke, 'Well, what is it?' without him having to say anything. Angered by the taunt, the Warbeast acted on its own accord and roared a wave of flames at the Slayer, drowning him in fire.

\\\//////

Rainbow Dash watched in horror as the armored killer was engulfed in flames. She cried out for the unknown hero. She didn't even know what he was, but he had just sacrificed himself to make sure that she and the other ponies in the Town Square could get out.

Before she could even think of shedding a tear, she noticed two green-clad hands grip the Warbeast's mouth while a boot pushed its jaw down. The pressure broke the Warbeast's jaw and the flames stopped as it went limp, revealing the armored killer, whose armor didn't even look touched.

He released his grip on the Warbeast as it slumped over, the Caribou rider jumping off in an attempt to escape. However, he tripped on the hoof-step and fell to the ground. The green guy grabbed the Caribou by the back of the neck and hefted him up.

"Please! Have mercy!" he begged, crying his eyes out.

The armored one gave no response, and dragged the Caribou to the front of the dead Warbeast. He lifted its mouth open with one hand and threw the Caribou into its maw.

"No!"

He slammed the head down teeth-first into the Caribou's midsection, the Warbeast's jagged teeth bluntly splitting his midsection in twain, not able to cut him clean in half. The killer left the Caribou in the mouth of his mount, bleeding through its teeth as he pleaded for anyone to save him.

The killer looked around again before going to pick up his weapon. He pumped it once more and nodded to himself. Then, he pointed at Dash and then pointed South. He let out a grunt as he turned about to hunt down the remaining Caribou.

Dash lifted herself and covered her breasts with one arm, and as she did, she watched with a fire in her eyes that hadn't been there before. She nodded to his backside.

"Fuck them up," she pleaded. "Make them pay."

\\\//////

Dainn slapped the pony princess before him and gripped her black collar tightly.

"Tell me where she's hiding!" he screamed in her face.

Celestia stared down at the floor, her eyes stinging from crying so much as she refused to give Dainn anything more than what he already had.

"Your midnight whore of a sister won't resist us for long! Either you tell me where she is so she can join you, or I can have her mind broken until she's an empty husk of a bitch!"

"She'll never break to you," she whispered bitterly.

Another slap echoed through Dainn's new bedchambers as he left the Sun Princess chained to the bed. He approached a fireplace and drew out a branding iron, a circular piece that depicted chains.

"She'll break like you will, and she'll beg for my cock like she it was the surface of her precious rock."

He came up to Celestia's flank and readied the branding iron, poised over her Cutie Mark, before his down was thrown open.

"Lord Dainn! Your- your majesty! I-" the Caribou was silenced from a magic blast that struck his throat.

"Learn your manners, boy!" he chastised. "Knock when I'm occupied with my Sun-slut!"

"ACK! For- kack-ack! Forgive me, Lord Dainn," the cadet wheezed out.

"State your business and pray I don't have you castrated for insubordination."

"My Lord, the town known as Ponyville-"

"You interrupt my training of Equestria's former Goddess to inform me that a small town has been conquered!?"

"No, sir... Something terrible... the... the Slayer."

The moment that word reached Dainn's ears, his excitement for torturing Celestia died, replaced by crippling fear.

"What of the Slayer?" Dainn asked in a whisper.

Celestia noted the mention and recalled what had happened earlier this very day. She chuckled darkly as she recalled the Magi's general reaction. This did not go unnoticed by Dainn, however, and he proceeded to whip out his cock and stuffed it straight into the treasure that he had claimed earlier. Her chuckled turned into a scream, and soon, Dainn began to take his aggression out on Celestia's marehood.

"Tell, me, that, they, managed, to, kill, it!" Dainn ordered with each harsh thrust.

"My Lord, they're all dead. One messenger managed to make it out alive, but... he committed suicide the moment he warned us. He said that we can't stop it, only prevent it from taking our lives by dying now."

Dainn reacted by slapping Celestia once more, the Princess crying out in agony as her senses were overwhelmed by both pain and unwanted pleasure. She squirted across the sheets and Dainn's crotch as the Caribou King groped her chest. The cadet waited for a response until Dainn's thrusts stopped and Celestia grunted in her attempt to keep her arousal in check, to no avail. As they both came, Dainn pulled out of the whimpering Princess and turned to the cadet.

"Tell them to fortify everything we have from each city to-"

"We don't have any other cities, my Lord."

Dainn stomped up to the cadet before grabbing him by the neck and slamming him against the wall.

"What!?"

"We- our forces were pushed back across Equestria! The Crystal Cock's magic hasn't reached past the Great North! The generals ordered a retreat to Canterlot and the Crystal Empire! They say that without the Magi, they'd lose all forces in the next week!"

Dainn managed his anger by throwing the cadet through a wall.

"Damn that Slayer! DAMN IT!" He cursed. "Fine. I'll have my sons fortify this city and crush the Slayer when he arrives while I go to the Crystal Empire and try and see why the Crystal Cock hasn't had our desired effect. And you," Dainn emphasized by magically pulling Celestia's collar, "will learn to love the taste of cum while we are there. Maybe have the pink bitch give you some lessons."

Celestia wept as she prayed that whatever this Slayer was, it would act before Dainn could retaliate.

Storming the Gates

"Fluttershy!" Rainbow Dash called out as she flew over the south end of Ponyville.

She was approaching the cottage fast, and was trying to find any sign of her friend outside. She could see from her height, however, that whoever that armored guy was, he had passed through here. Which either meant that he started his rampage against the Caribou here and saved Fluttershy, or...

She dove down to the cottage entrance and gagged as she saw something horrifying. Fluttershy was naked and covered in blood, cradling a limp Angel Bunny as she nestled against Harry's corpse.

"Fluttershy," Rainbow choked out, not bothering to hold back her tears.

The yellow pegasus looked up to see Rainbow there, her eyes red from crying over the death of her animal friends.

"Rainbow..."

"Did... did that... thing, do this?" she gaped.

Fluttershy ran a trembling hand over Angel's ears and shook her head.

"He... h-he came here after th-they were m-m-m-mmm..." she broke down and started crying.

Rainbow rushed to her friend and threw her arms around her, stroking her mane as they held on to each other. They sat there and cried together, unable to cope with their dramatic shift in how their worlds were destroyed. Fluttershy sniffled and spoke after a few minutes of silence.

"He... h-he's going to kill them all," she whispered.

Rainbow paused her stroking of Fluttershy's mane and looked her in the eyes.

"A-and... I don't know if... I want to stop him," she whimpered. "What... what's wrong with me?"

"Fluttershy, there's nothing wrong with you," Rainbow reassured by nuzzling her. "I want him to stop them too."

"No, Dash. I-I mean... I want them to suffer... I want to know that they died in pain and afraid... I... I feel sick... I feel like some kind of monster!"

Rainbow held her friend closely as she whispered into her ear.

"We've all got a voice like that, Shy. But what's important is that we don't follow through with it, alright? You're not evil or a horrible pony because you thought of it. The Caribou acted on whatever shitty belief they had and that's what makes them monsters. But whatever he is... sometimes... I think someone needs to follow that voice, and I think we should be glad he's going through with it for us."

"... Doom."

"What?"

"I asked him what he was... he said, 'Doom'."

"... Well, I guess he's some kind of... Doom Guy, then," Rainbow said.

\\\//////

Doom Guy slammed the underside of his boot into a Caribou's head, crushing it against the wall of a nearby house while giving the laws of physics a serious rage boner. Whatever kind of erection of anger that the laws of the universe may have held for Doom Guy, however, were overshadowed by the great obelisk that was his own sheer hatred manifested into his own pillar.

Turning the corner, the Doom Marine saw the Caribou retreating through a portal, someone with a staff of some kind on the other side.

"It's here! Close it!" one of the Caribou on the other side shouted.

They tried to react, but their will over Demonic energy wasn't able to keep up with Doom Guy's speed. He jumped through the portal, drawing out his Plasma Rifle, and unleashed its alternate fire. The Caribou were cut down by the sheer force of the rifle's output before their flesh and bones melted and fused together from the heat of the blast, setting their coats on fire as they toppled to the ground.

The one with the staff, however, managed to throw up a transparent orange shield in time to protect himself from the weapon's discharge.

Disregarding his advanced arsenal, Doom Guy settled to put this one down the good-'ol fashioned way.

He punched straight through the shield and grabbed him by the antlers before slamming his face on the inside of the bubble, breaking both his concentration and his nose. Blood began to pour out of his face before Doom Guy threw him to the ground. The armored Marine picked up the fallen staff and twirled it about so that its gem end was facing the Caribou's backside, which was facing upwards while his face met the ground. Doom Guy pulled him up by the waist and moved his robe aside to reveal a puckered hole.

If they valued having a hard wooden rod above all else, then this was surely going to be something that the Caribou would appreciate.

The Caribou screamed in agony as his back hole was penetrated by the staff, burning away at his prostate at it glowed red with the rage that the Doom Marine was unintentionally channeling through it. However, the Doom Marine showed no mercy for the Caribou's first time on the bottom bunk, and rammed the wooden shaft further in before dragging it back out, only to plow it straight through his gut as the gem burst apart.

Satisfied with his impromptu shish kebab, Doom Guy picked up his Plasma Rifle and examined his surroundings.

Everything around him was a horribly bright shade of white. It wasn't the sterile environments of the UAC base, no, this had a more... anti-Hell theme to it. The golden highlights in the buildings didn't help either, as they made it more unbearable to be in.

"Stop right there, Slayer!"

Doom Guy turned to see a group of Caribou block off a street, all wearing heavier armor while hefting about larger hammers and even a few swords.

"In the name of Lord Dainn, we will stop you here and now!" the one in front said, brandishing a large double-headed axe.

At least he'd be able to paint his path a more pleasant color.

\\\//////

"What do you mean, 'she's gone'!?" Dainn shouted at the General.

The stone-masked Caribou before him cowered back in fear as Dainn's fists glowed a sinister red. He gulped down whatever moisture remained in his throat before addressing his King.

"What I mean, my Lord, is that... we left the Pink-Princess slut in the main foyer to prepare for your arrival, and when the groomer arrived, all he found was her collar and a note."

"What did the note say?" Dainn strained through gritted teeth.

Another Caribou came up, holding the note before him as he read.

"'Dear shitlord, we hope you've had an awful time as of late. Since you were so near-sighted with how your implement worked with Stallions as opposed to mares, we were able to circumvent its effects and warn the rest of the country while you focused the bulk of your forces on Canterlot. Enjoy what little power you have now, because now you've surrounded yourself with enemies that cry out for you head on a pike that will die a thousand deaths to ensure your demise. You think that because you've taken Celestia, you've won? You wouldn't be able to even start cracking her down before we take back our home. P.S. What did you think would happen when you tried to brainwash a Captain of the Royal Guard who had experience prior with mind control and a Princess who rules the shadows?'"

Dainn clenched his fists tightly before throwing them at the nearest wall, annihilating the crystal structure with a massive burst of Argent energy.

"Find them! I will not have my regime ended because of some traitorous half-dick stallion that gets off on mares dominating him, and some cunt that sat around fucking rocks for a thousand years!"

The soldiers before him scattered like the wind, running off to follow his orders. Dainn slumped into the Crystal Throne and rubbed his temples.

"This was supposed to be our time to rise," he spoke to no one. "It was supposed to be a glorious revolution that would save males everywhere... how have we managed to lose so much in such a short period of time? Ugh... if there is any solace to this, maybe I'll be able to strike fear into them when they learn the fate of their Slayer when that fool walks right into Canterlot."

\\\//////

"AAAH!"

A random Caribou was thrown into the side of a building, his spine shattering upon impact with the marble structure. His body was dug into it, however, and if he could still feel anything below his neck, he would have tried screaming in agony of the jagged stones that cut into his body.

Ignoring the impaled Caribou, the Doom Marine walked around the corner as he slapped the side of his Plasma Rifle, the battery readout coming up blank.

"I believe we need to find a suitable battery of Argent Energy to replenish our ammo," VEGA informed.

Grunting in a way that spoke both a thanks and an insult for stating the obvious, Doom Guy watched as more and more Caribou started to pile into the street before him. These ones had giant shields and began to form a wall with them.

"Slayer!" some jackass shouted from his comfort zone between his wall of meat-shields, "you cannot penetrate our wall of righteousness! Lay down your weapons and we will make your death quick!"

Doom Guy gave a brief chuckle as he pulled out his Rocket Launcher.

"What is that?" an actually aware Caribou asked. "No, seriously, what is that?"

Doom Guy gave him the answer in a barrage of fire and explosions.

Rockets streamed out of his weapon and impacted the ground by their feet, the blasts crushing, burning and sending bits of shrapnel into the clustered Caribou. Limbs and guts fell apart as screams and booms echoed through the streets of Canterlot. Bits of stone and steel flew in different directions, one fortunate Caribou managing to have a cut section of a shield slice through his head, destroying his brain instantly while those around him bled and burned.

Satisfied with the destroyed state of their Phalanx formation, the Doom Marine strolled up to one of the Caribou that managed to survive the onslaught of explosive persuasion. He grabbed him by the neck and slammed him face-first into the ground, crushing his head in and staining the road.

He repeated this with about three more unlucky survivors before something nearby roared loudly. A massive creature came up to the street, walking on six legs that ended in tentacles. Its body was covered with a blue, chitinous armor that was leaking a disturbing amount of white sticky stuff, even more tentacles reaching out from its plates, and its face carried one giant eye and, what a surprise, more fucking tentacles!

"It strangely resembles animated footage archived in the Barracks' casual lounges," VEGA informed.

"Behold, Slayer!" a blue-armored Caribou shouted from a saddle atop the beast. "This is your end! You will be raped to death by my personal pet, The Defiler! Now behold the might of a creature that only an Heir of Dainn can achieve!"

The Doom Guy watched as the creature slumped about, sliding across the marble to reach him. Just as he was about to dive out of the way, something erupted up from the ground. A series of blue tentacles wrapped around his boots and held down the Doom Marine as the Defiler closed in.

"There is no escape!" the rider shouted.

Before Doom Guy could think of an out, the Defiler was upon him, and swallowed him whole into a mass of acid coated tentacles. As the Slayer was sucked into its gut, the beast held its head high to swallow, and eventually, its prey went down.

"Hehahahahaha!" the rider bellowed. "I've done it! I've beaten the Slayer! Let's see who those thick-skulled morons worship when our father elects me as his sole heir when he learns that I've won!"

His laugh of victory was short lived as the Defiler lurched about, side to side, spitting up bile and blood. Before the Son of Dainn could interpret this as a sign to flee, he heard a growling noise underneath him.

The chitin underneath his saddle burst apart, the bar of a chainsaw reaching out like a vengeful sword. And vengeful it was, as the chain cut through the saddle and dug into the flesh of the rider, shredding through his crotch in the most intense pain that the Son of Dainn had ever endured. His testicles and penis were ripped apart as the chainsaw tore through his lower intestines, crushing and mixing his bone fragments with his internal fluids as he was split in half the way that he thought a mare would.

Unable to comprehend the pain any longer, the Caribou's brain ceased to process anymore and he went limp atop his mount, who died that same instant.

The chainsaw was pulled back into the Defiler's bowels before erupting through the side, cutting out a hole large enough for the Doom Marine to fit through. His armor was coated in acidic compounds, sizzling and burning at the contact of the outside world's air. It wasn't enough to do more than dim the paint on the armor, however, and caused little more than a nuisance for the Doom Guy.

He stared up at the castle before him, and cursed to himself as he played around with different ways of maiming his next victims.

Bring the House Down

Two Caribou stood guard at the entrance to the Grand Hall of Canterlot Castle. They looked between one another as well as the door, waiting for their moment to shine.

"Hey," one of them called over.

"Yeah?" the other answered.

"... we're kinda fucked, aren't we?"

As the Caribou reflected on their ultimate truth, they heard the battle raging on outside.

Their attempt at mind-fucking-curing the stallions of Equestria had backfired considerably, since a majority of the Royal Guard were wearing enchanted helmets designed by Shining Armor himself in retaliation of the Changeling fiasco. In hindsight, maybe it wasn't a good idea to mind-control a population that was preparing for a race with mind-control capabilities.

"Yeah..." the other Caribou sighed.

"I mean, why did we even think Dainn's plan was good? Just stroll in here and take everything for ourselves?"

"It worked with the Sun-slut, didn't it?"

"Well, yeah, but we're not getting any, so I'm calling it a failure."

"Fair enough."

"And now we've got orders to slow down the Slayer while Dainn's children prepare to finish it off."

They stood there, swallowing their orders like one would swallow a sandwich.

"Wait," the other said, tasting the shit smeared underneath the lettuce of their second-handed BLT, "they said 'slow it down'?"

"Um, yeah... why?"

"Shouldn't we try to stop it if we can?"

"I think they're implying that we won't be able to stop in more than anyone else, so we're just meat shields to try and buy them precious seconds to formulate some kind of plan... but I think we're just a distraction while they have their way with Celestia's student and are using the Slayer as an excuse to get one last rutting in before-"

The doors before them burst open to reveal the Slayer running in, carrying a Great Lance that belonged to a Warbeast Rider. Speared on the lance were no less than five Caribou, hanging limply as he rammed through them.

"-exactly that happens. Well, it's been a horrible time knowing you," he said, resigning to his fate.

Doom Guy chucked the lance forward, sailing it through the air and impaling his sixth straight kill with the weapon, pinning the Caribou to the marble floor with it.

"My only is regret is that I-" never finished his sentence, as Doom Guy grabbed him by the neck and impaled his face into the dented handle, marking the seventh kill with the weapon.

Satisfied by his handiwork, the Doom Marine nodded in appreciation to his addition to the castle's modern art exhibit before turning to see some winged Flutter-somethings screaming as they decapitated Caribou in the streets, bathing in their blood as they screamed for their deaths. When they laid eyes upon the Slayer, something within them lit and they fought with a ferocity that hadn't been seen in eons.

"Rip and Tear!" a Unicorn follower of the Doom Marine cried out as he pulled an antler out of a Caribou's skull before slashing his throat with it. As the Caribou fell to the ground, clutching its neck in a feeble attempt to retain its life, the unicorn stomped on its neck and reveled in the bloodshed. When the neck was split open enough to the point where the Guard looked like he had just procured an expensive carpet/boot-cleaner, he looked to the Doom Marine.

Doom Guy responded with a thumbs-up.

The unicorn cheered as he stormed through an adjacent hallway, gripping the bloodied antler like a knife.

The doors before the Doom Marine were sliced apart before being blown away, showering the unmovable Doom Marine with splinters and ornate metal designs. On the other side stood two Caribou, one wearing a wrapping around his eyes that was as black as his leather armor, wielding a curved blade that looked like one of those things that some casual scrub would spam like a disgusting fucking Weeaboo.

The other figure, standing nearly a full meter taller than the Doom Guy. He had massive plated armor and forgone any actual weapon to instead use two great shields as a crushing wall of might. This managed to get a slight nod of respect from the Slayer, but little else.

"We've come to stop you, once and for all, Slayer," the Weeb said in a Weeb accent, trying to sound cool and failing miserably by default.

"You will not topple our defense," the wall of a Caribou stated.

"I am Master Virces," the idiot muttered, holding the Weeb sword at his hip, sheathing it in an attempt to look remotely interesting.

"And I am the Wall," the giant mass said before him.

Doom Guy had enough of their talking and pulled out his baby girl, letting her barrels hang downward.

"You've slain too many of our brothers, and for your desecration of our forefather's practice, we have no choice but to ensure that no flesh shall be spared."

Doom Guy loaded in the first shell.

"We will crush you until your armor is flattened into the road," the Wall started. "We will ensure that your last moments are that of pleading for the end to come, as you saturate the ground beneath us to last generations."

Doom Guy loaded in the second shell.

"We will be written as heroes while the Stags of the Stonehoof tribe sing our names as they break the mares of this pathetic country like the ungrateful sluts that they are!"

Doom Guy flipped his baby girl closed.

"Now suffer the wrath of the Twin Princes!" they shouted simultaneously.

The Wall charged forward, his shields at his sides as he steamed towards the Doom Guy. Virces faded from sight, leaving only afterimages behind as he leaped from wall to wall, trailing only dust and the sheen of metal. They closed in on him from both the front and the back, ready to end his life in an instant.

Doom Guy pointed Jessica over his shoulder and pulled the trigger.

The Super Shotgun thundered much like Doom Guy's own climax as he felt the kick of his beautiful companion unload all over the unsuspecting wannabe-ninja behind him. Virces burst into a shower of shrapnel and gore, his uchigatana breaking into a hundred pieces as Doom Guy let Jessica's burst push his arm forward, using his elbow as a fulcrum for her descent. When she was leveled with the Wall, he pulled the trigger again, the shotgun's blast an obvious metaphor for what was happening within the Praetor suit. The Wall was sent flying back as his midsection was shredded and eviscerated by the blast, his ribs and spine visible from the clear third of him that was cut out.

As VEGA cleaned up the mess inside of Doom Guy's suit, he popped Jessica open and loaded in two fresh shells as he examined the Wall die slowly as he gasped for air. He looked up to the door that they came out from and noticed a large group of Caribou standing there, one of whom had decided to dye his pants brown and yellow. Doom Guy smirked as they screamed and retreated in a desperate attempt to save their lives.

How fun it was to hunt them down.

\\\//////

"Are you fucking kidding me!?" Dainn roared.

He seethed Argent Energy in arcs of red lightning as he saw the empty streets of the Crystal Empire.

"Where are the slaves and stallions!? Why are they gone!?" he demanded.

Dainn kicked a nearby building, destroying the support and ripping it from its crystalline foundations before it toppled over away from him.

"Why has nothing gone right!?"

Dainn looked down and spotted something that irked him: a letter addressed to him specifically. Calling it forth with his magic, he read the note as it hovered in front of his face.

'To the professional Anus Taster, Dainn,'

Don't fuck with the Crystal Empire.

They'll only bow down to one overlord, and that's *me*.

Forever your superior,

Queen Chrysalis

P.S.

Just because they've been my target before, doesn't mean you can get away with attacking the Equestrians. I'm sure your little hometown of Eichenwalde would simply adore the Slayer's company, once this is over.'

Dainn incinerated the note from the Bug Queen as he roared in sheer rage.

"I WILL HAVE YOUR HEAD, SLAYER!!!"

\\\//////

"Do you think that those barricades will hold?" one Caribou soldier asked.

"They have to. We don't know when reinforcements will arrive," an immaculately dressed Caribou answered. "As the heir to the throne, I say that-"

"That's a load of broken does, and you know it!" a taller Caribou cried out. "I'm the heir to our Father's throne, and none of you are strong enough to usurp me!"

"Can we focus on surviving this before we start backstabbing each other for the bloodline!?" another Caribou cried out, cradling a hammer closely. "We've to focus on what happened with the males here! How did they become so-"

The barricade furthest from them buckled and shook, the stacks of furniture toppling a bit as the ponies beyond it screamed for blood. On the opposite end of the Throne room, fire and smoke pooled above the door frame, eluding which angered being lay behind it.

"I thought that the enchantment that we used on Spike the 'Brave and Glorious' would have induced his primal urge to mate and hoard! He shouldn't be able to think about anything other than subjugating the mares!"

"Clearly it triggered something else! Look, right now, we need to think of an out."

"Maybe we should open the portal, and-"

"No! Father told us to keep the portal closed at all times! Even if we are to die here!"

"There is no, 'if'!" a pony behind the barricade shouted as they continued to assault their defenses.

"Shut up you filthy traitors!"

"Rip and Tear!" they chanted as they slammed the doors.

As the mantra repeated, none noticed the heavy footfalls outside the main hall before a Caribou outside shrieked. One Caribou came flying through the doors, his spine snapping in half as he sailed through the broken pile of stuff meant to hold the door shut.

"The Slayer!"

The Doom Guy walked forward, reloading Jessica as one stupid Caribou thought that he could catch him off-guard. Loading in the second shell, Doom Guy grabbed him by the throat and hoisted him upwards, crushing his windpipe slowly. Another tried to retaliate, but was quickly dissuaded when Doom Guy brought up the fact that he was late for his meeting with Death, promptly assisting him by replacing his innards with shrapnel and lead, propelling him to the other side at the speed of 'Fuck'.

Snapping the neck of the struggling Caribou, Doom Guy used the corpse as a weapon by hurling it into the two charging him before grabbing a grenade off of his belt. One Caribou had the sense to duck underneath the corpse-toss, and was rewarded with the privilege of meeting Doom Guy's boot, face-to-heel.

The Doom Marine tossed the grenade across the ground, sliding it underneath the shield-bearers, counting down in his head as he jumped over them in time to catch the shock wave of its detonation. The explosion propelled him high enough to get a shot off on the last few in his way, shredding their upper halves to shit before landing before the thrones, cracking the stone floor upon landing.

"We're all gonna die!" one of the Sons of Dainn shouted in panic.

"Finally, I can face you at last," the armored Son of Dainn triumphantly shouted. "Now, let's see how you-"

He never finished as Doom Guy swept his right foot underneath the Caribou's feet before bringing his fist down against his skull, staining the carpet and thrones with blood and brains.

The two remaining Sons inched away from the death of their brother as the Slayer craned his neck to the side.

"I'm not dying like this!" one of them shouted as he ran towards one of the windows.

Just as he did, however, the barricade burst apart and let a purple form through.

"SPIKE RIP!"

The Caribou cried out in fear as the Dragon hefted him up by a leg before gripping an arm.

"SPIKE TEAR!"

The Dragon pulled apart the screaming Caribou, his spine and intestines dangling out and dragging across Spike's face. He opened his maw and spit out green flames that seared and burned the inner flesh of the Caribou before chomping down on it and swallowing chunk after chunk.

Doom Guy turned around to see the third Caribou's horns glowing as a small hole began to expand in between the thrones. He caught the sight of the Slayer marching to him and protested.

"I can lead you to my father! Just spare me, please!"

The other barricade fell, and nearly two dozen gold-clad ponies poured in. They stopped in awe as they watched not only Spike devour one of the Sons of Dainn, but also the Slayer.

"I can help you kill Dainn, give you information on his weaknesses, let you know how to avoid his magic, and- guck!"

Doom guy gripped his antlers and pulled him close. He didn't need a strategy or help on killing this 'Dainn' fucker he'd heard too much of. He already had a winning solution.

Shoot him until he dies.

The Guards began to chant.

"Rip and Tear! Rip and Tear! Rip and Tear!"

As if Doom Guy didn't have enough motivation.

The Caribou screamed as Doom Guy pulled his antlers in separate directions, his scalp breaking open as his skull began to give. With one pull, Doom Guy split the Caribou's head in half and tore half way down his torso.

A Fitting End Pt. 1

"Damn it, he got away!" Spike shouted as he punched a wall.

"Dainn may have escaped, but his armies are crowding towards the south of Canterlot right now! We're going to need to fortify our position and dig in before those zealous shits try and take the city!" some guy said.

The crowd cheered in approval at his statement, but behind them all, standing between the shattered thrones, the Doom Marine stood staring at the tiny blip that was supposed to be a portal.

"The portal is still technically open on both sides," VEGA expositioned. "However, in its current state, it would take a great deal of Argent Energy to expand it while maintaining a stable connection."

Doom guy grunted as he racked his brain for ideas. Shooting it wouldn't work (as he already tried that, much to the wall's dismay) and punching it didn't do much (much to the thrones' dismay).

"Lord Slayer, sir," one brave soul spoke to the Doom Marine, "what plan do you have for that portal?"

"I wouldn't try anything else if I were you," Spike said, almost meeting the Doom Guy in height. "I mean, it's not like you could just rip it open."

Of course! How could the Doom Marine have neglected his tried-and-true method of solving problems?

Doom Guy cracked his knuckles.

"He's gonna rip it open, isn't he?" Spike blanched.

Doom Guy planted his boots firmly into the marble as he reached his fingers into the portal and gripped its inner ring. Argent surged from the fringes through his armor, his HUD flickering wildly as he began to force the edges further and further apart. The Doom Marine grunted and exhaled as he put more effort into tearing the portal open. Reality began to waver and quake before his might, and with one final pull, Doom Guy tore this dimension's anus asunder.

The hole gaped and flickered before Doom Guy as the ponies behind him cheered and whooped for him.

"Kill that bastard dead, Slayer!" one of them shouted.

Doom Guy jumped through the portal, and seconds later, it collapsed into nothingness.

When the Slayer landed on the other side, his boots crunched against the glass-like surface as he stood up.

He seemed to have teleported to an entirely different part of the world, as the sky was dark and full of storming clouds that let snow down while the buildings around him were made of the same kind of glass that the street was paved with.

In front of the Doom Guy was a massive wall of Caribou, all barring their hammers as they stood shoulder to shoulder.

"It's over Slayer!" some fucker shouted. "We've got you outnumbered 100 to one!"

This seemed like quite a problem. Thankfully, Doom Guy had a 9-barrelled solution that could solve up to 900 problems a minute. He reached into the ether and willed forth his preferred method of dealing with large crowds and began to spin up all three triple-barrels.

"Get him!"

The Caribou charged forth with a combined war cry as Doom Guy smiled broadly under his helmet.

He pulled the trigger.

15mm tungsten rounds poured forth from the Chaingun, each round ejected with more than 220,000 PSI as they found their new homes within the flesh and bones of the Caribou. The storm of firepower surged through their lines, shredding the iron and leather armors of the Caribou while reducing their flesh to a fine paste. Shrapnel and burnt flesh made up the scent of the city as Doom Guy strode forward into the carnage that his little friend laid down. The hundred Caribou were reduced to nothing more than a bleeding lump of seared flesh, broken bones and shattered steel as the Doom Marine stood at the top of the gore.

In the center of the city stood a massive spire, which VEGA marked as the source of streamlined Argent that the Caribou seemed to channel. A new target in sight, Doom Guy strode forth to end this species.

\\\//////

Dainn roared in rage as he sent a bed flying through a nearby wall, enraged that his only legitimate prize had been stolen the moment he looked away.

"How did they take that dumb cunt so easily!?"

Dainn was so enraptured in his own rage that he didn't even hear the gunfire that echoed through the Crystal Empire until it started to thunder from beneath the Crystal Tower.

"Slayer!"

\\\//////

Doom Guy felt another Caribou cry underneath his boot before he shoved his leg down through his chest, crushing bone and flesh with ease. He fired another barrage from the Chaingun before the cycling cylinders clicked as the weapon beeped.

"We are out of ammo for all weapons," VEGA said.

Doom Guy grunted before seeing another Caribou charging at him. The marine spun around the Caribou before knocking him to the ground and slammed the Chaingun above the poor shit's head, fitting him right in between all three rotating units. Doom Guy then spun up the gun, the chambers spinning fast enough to tear the Caribou's head apart in a twirling mess of gore, splattering innards all over the crystal pavement.

"Slayer!"

The Doom Marine looked away from the Caribou soup he had just finished to see another deadman walking. This one was wearing gold-plated armor and held a single-edged blade in his right hand as he glared hatred at the marine. Doom Guy accepted the unspoken challenge and released his hold on the Chaingun before cracking his knuckles.

"You dare to come into this world and oppose our great rule?" the baby cried. "You dare stand against the march of male dominance? You dare kill my fellow Caribou? You dare to stand against the almighty Lord Dainn!? This is your end!"

Doom Guy was about to charge at the apparent leader of the Caribou before his horns glowed a familiar red. The light arced towards Doom Guy before a paralyzing pain erupted across his flesh. The marine was frozen as he fought against the overwhelming surge of Argent, but only for a moment as Dainn lifted his left hand up, causing the Argent to lift the Doom Marine into the air.

"You are worthless!" Dainn shouted as he threw his arm out to the side.

The Doom Guy flew through the air in the same direction before he was slammed against one of the four large supports to the Crystal Tower. His armor buckled and a small fissure opened up on one of his back plates as bones began to crack under the pressure.

'Administering nanomachines," VEGA announced.

Before the pain could subside, Dainn hefted the marine out of the massive badass-shaped crater in the building before throwing his arm down.

"You are powerless!"

Doom Guy felt a few ribs snap as he was thrown down into the hard crystal surface of the ground, his visor cracking a bit as blood stained the inner glass.

"You are nothing compared to ME!"

Dainn threw his hand over his head, sending Doom Guy high into the air before he was brought back down with twenty times the force. Shards of crystals and dust burst out from the impact, hiding the marine.

"I am the legacy of a God!" Dainn monologues. "I am the heir to a throne that has existed before your kind learned how to walk! I am Dainn, the Lord of Caribou and I will be the one to slay the so fabled 'Slayer of Gods'. You might have killed those that our ancestors once worshiped for our power, but now you face a true force of might, so great that not even Equestria's Sun goddess could hope to resist! I am the pinnacle of male superiority, and when I am through here, I will find your world and conquer your sluts as well!"

"Rerouting excess Argent to BFG."

Doom Guy smiled as he rolled over.

"And look at you now, Slayer! Crawling onto your back to accept your fate as a whore! No, I don't think I'll kill you just yet. I think I'll turn you into a bitch and rape you until you need my seed to so much as breathe."

Dainn walked up to the Slayer and set a hoof atop his armored chest, twirling the sword about before holding it right over where most people's heart would be.

"I would if I were an idiot who didn't believe in vengeance," Dainn whispered as he scratched the Doom Guy's armor. "I'm no fool so obsessed with self-indulgence that I wouldn't kill the most prominent threat to my kind."

Dainn raised his sword into the air.

"DIE!"

And plunged his sword straight through the marine's heart.

Doom Guy hacked up a wave of blood, coating his face in crimson as he felt the Argent infused steel slice into his armor and flesh. The familiar burn of a Hell Blade seared his inner flesh as he hissed in pain.

It's not like he hadn't tanked worse.

Dainn faltered a bit and backed off as he heard the Slayer's dark voice chuckle.

"What... why are you laughing!? You dare laugh in the face of Lord Dainn!? I've pierced your heart with my sacred blade, and now here you are, dying at my hooves like you did to so many of my brethren! What about his is funny to you!?"

Doom Guy responded by materializing the UAC's pride and joy.

Dainn froze as he saw the weapon come from the ether, and felt the sheer power that began to charge in the barrel of the weapon. He could have sworn that a nightmare of a smile was bleeding through the Slayer's helmet.

A nearby Caribou that hadn't yet died stared in awe at the weapon before speaking his final words.

"That's a big fucking gun."

The world went green as Doom Guy pulled the trigger.

A Fitting End Pt. 2

Celestia and Luna coughed as they used their magic to dispel the dust that had been kicked off when the burst of green energy went off.

"Wha-ack-agh-at was that!?" Luna half-shouted as the debris ceased to shake.

"That... must have been the wrath of the Slayer," Celestia said grimly.

"To think that such a force had rampaged through Equestria not too long ago," Luna shuddered. "Do you think it died in that blast?"

"We're more likely to see Discord as an Element Bearer. I've read the ancient texts that depicted the Slayer while you were gone, Luna. He makes our fights look like preschool roughhousing."

The sisters watched the Crystal Empire as the light from the eruption started to fade away, allowing them to see the remains of the Empire.

"Stars above," Luna gasped.

The Crystal Tower that once shone brilliantly was now a bare thing, all of its crystals stripped away to reveal ancient wood and iron, the nearby housings having been reduced to ash from the blast.

"Are you sure this Slayer could have survived this, sister?" Luna asked.

"I'm afraid to look through the rubble in case he might think of us as a target."

"I think it's worth a look," a voice said behind them.

Celestia and Luna turned to see Discord standing behind them with an irate expression.

"Discord!" Luna shouted. "Where were you when Canterlot was being raped!? Where were you when my sister needed your help!?"

"The Caribou had used Demonic Runes to hold me down until either I was drained of all energy or I converted to their disgusting way of thinking. I only just got out now, and I wanted to thank the Slayer for saving Fluttershy. Let's go."

With that, Discord teleported them to the epicenter of the BFG's destruction.

\\\//////

Amidst the rubble and ashes that had once been the Crystal Empire, a single glowing object could be seen. A perverted fragment of the Crystal Heart, reforged and cursed to corrupt the minds and bodies of Equestrians everywhere. This unholy abomination of what was once a symbol of unity floated above the destroyed portion of the city, crackling with rage and hatred as the minds it sought to corrupt redirected its power into a desire to kill and maim to protect themselves.

Aside from the Crystal Cock, a burned hand grasped onto a fragment of its stand.

Dainn pushed a chunk of burned crystal off of himself as he gasped for air, only to cough up blood and specs of his inner flesh as he crawled to his only lifeline.

"No... i... it c-can't be..."

The Crystal Cock, once a conduit of Caribou magic to spread unbridled lust and the mindset of male dominance across Equestria, now glowed with menace and anger, a conduit of bloodshed that urged Equestrians across the nation to rip and tear. Even now, Dainn could feel what little that kept him alive fading into nothingness amidst the sea of hatred.

The former Lord of Caribou examined what little of himself remained from the Slayer's final act, and blanched as he realized his end was near. His legs were but stumps of charred meat and bone, his mighty Kingly scepter reduced to nothing (so not much of a difference), and his torso was sporting a large crater from the weapon's blast. Even with all of his holy and demonic powers, Dainn barely managed to survive that attack, and would succumb to it anyways. He pondered why he had survived if he were only to die when his magic would run out.

He turned towards a shift in the rubble and froze.

The Slayer rose out of the ashes with nary a scratch on his armor. Dainn's sword was still piercing through its chest, and its helmet sported a large crack, but other than that, nothing about the Doom Marine suggested that Dainn had managed to land a single blow against him.

"No..." Dainn gasped as he hugged the Crystal Cock's stand, failing to draw anymore power from it.

The Doom Marine stalked towards the cowardly King as he cracked his knuckles.

"No!" Dainn cried as two of his burnt fingers fell off, causing him to collapse to the ground.

The Doom Guy reached up and unlatched his cracked helmet before tossing it to the side.

If Dainn's innards were working properly, he would have pissed out his ass and shat out his dick.

The Slayer's face was that of brick and mortar, unflinching and unbreakable, sporting a great deal of scars. His jaw was square and chiseled as though it were freshly cut for a cornerstone of a mighty fortress. Atop the Slayer's head was a weave of dark gold hair, and those eyes...

Dainn screamed in fear.

"Mercy!"

The Doom Marine grabbed Dainn by the throat and lifted him up to eye-level, scowling and glaring pure rage into his very soul. Whimpering and cowering, Dainn pathetically tried to peel the Marine's fingers off of him, only to have them break off as well. This was the being that brought death to thousands of his brothers and children. This was the creature that destroyed everything that he had worked for, and now it was the one who would end his life. As everything that Dainn had ever accomplished burned and crumbled in the world around him, he muttered one last word.

"Why?"

The Doom Guy reached out and ripped the Crystal Cock out of the air before shifting his grip to hold Dainn's mouth open. With a voice that shook the world, the Slayer spoke.

"You pissed me off."

Doom Guy slammed the Crystal Cock into Dainn's mouth, shoving its flared head down his throat before reeling back and punching the base of the fake dick. The force broke Dainn's jaw off its hinges and tore into his esophagus before tearing straight through what remained of his body, shooting out his ass as Dainn released a small cry before his eyes lost all life.

With that, the Doom Guy threw the King's body to the ground, satisfied that Angel bunny had rightfully been avenged.

Epilogue

\\\//////

Three Years Later

\\\//////

"Keep pushing them back!" Luna shouted over the hail of gunfire. "We'll take this land and burn and salt it until they're but dredges of guts and dirt beneath our hooves!"

"FOR EQUESTRIA!" came the chorus of Equestria's reformed army.

Ponies of all kinds and backgrounds charged over the rubble of cobblestone and iron, each one wearing a green suit of composite materials to withstand the new weapons that they now carried into battle. Showers of lead and explosive rockets sailed overhead as the Equestrians charged the borders of Eichenwalde, stomping over the corpses of Caribou as they pushed in.

"Clear the area!" a mare shouted from the gates.

Nightmarish energy rippled the space in front of the city until massive beasts of red writhed from the tear in reality, screeching and roaring as they swiped at nearby Equestrians.

"Fire in the hole!" a maroon stallion shouted.

A burst of flame erupted from the barrel of his massive cannon, the demon exploding into a shower of gore as the explosive device impacted its hardened flesh. As it recoiled in pain from the surprise amputation, nearby soldiers began to concentrate their weapons on its opened innards. The combined firepower from their automatic rifles and pump-action shotguns brought the beast to its knees, whereupon Luna flew up to its face with her new weapon.

She pulled back the cord on the end of the sword's handle, the inner engine rumbling awake as the teeth of the two-meter long blade began to run down the track of the sword before she plunged the mechanical weapon into its maw, forcing it upward until its eyes began to pour blood. After another few seconds of this, she tore upwards with another heave and ripped the skull of the demon in two.

As the beast dropped dead, soldiers began to throw themselves against the massive doors to the city, forgoing their firearms as they unleashed the rage of the Fall onto the barrier that tried to cease their advance. Luna flew above the wall to the city and examined the other side, her metal-plated armor deflecting a few spells as she saw the Caribou mount their last defense.

\\\//////

"And once we wipe out the last of Dainn's loyalists, we can begin indoctrinating the surviving does and young," Blueblood proposed.

Celestia slowly nodded along as she strained herself to keep a neutral look.

"Very well. Have there been any other developments?" she said.

Looking over the refurbished war-room, she was able to see a live feed of the battle for Eichenwalde, currently from Luna's view, broadcast on the center screen of the wall. In the middle of the room sat a white-plated terminal with a strangely shaped triangle in the center. From this terminal came a voice.

"The surge of Argent Energy in the Eastern continent has been identified and located," VEGA said. "I can send the Marine in at any moment, should we need to."

Celestia shook her head as she cracked her neck.

"No, it's my turn now."

"Understood. I will inform the Marine that he does not need to be present."

\\\//////

Fluttershy sighed as she stretched in her lawn chair, the chirps of the birds and the running stream beneath the nearby bridge lulling her into a serene calm that she was ever so thankful for. Cracking an eye open, she spotted a familiar figure approaching, his hulking form casting a long shadow over her.

"Something wrong, Doomy?" she said.

The Doom Guy held up a small device to her, the line of text reading, Orders retracted.

"Oh, it's okay, I'm sure you'll get a work day soon."

The Doom Guy proceeded to crush the device in his hand before gesturing to her.

"Of course," Fluttershy said before getting up.

Doom Guy then proceeded to sit on the chair himself, the steel and plastic groaning in protest at the weight of his sheer muscle mass. Fluttershy then proceeded to sit on top of the Doom Marine as he pulled out a comb from under the chair. She laid over his body before curling up a bit so that she was resting on him entirely, the Marine slowly starting to brush her mane as a small smile cracked on his face.

thump

A figure stood up from the shadow behind the chair, a broken horn sticking out of the side of the figure's head as it glared at the Doom Marine with one eye.

"You monster, I'll have revenge for my people!" the Caribou shouted as it pulled out a knife.

"WRYYYYY!"

A white mass then impacted on the side of the Caribou's face, the victim screaming in agony as the small animal began to eat its way through his eye. It then tunneled through the large open space inside the Caribou's head before ingesting its minuscule brain in one gulp before clawing its way out of the skull.

As the body hit the ground with a solid thud, the rabbit hopped over the chair and landed on Fluttershy's lap, the mare gasping at the sight.

"Angel Bunny!" she cried with a smile.

The rabbit squeaked in joy as Fluttershy cupped the bunny before nuzzling him affectionately. As she did, Angel gave the Doom Guy a thumbs up, to which the Marine responded with a large grin and a thumbs up in return.

Reckoning of Lead

The slapping of flesh on flesh echoed throughout the once great halls of Canterlot Castle.

Banners of the once mighty Twin Sisters, Celestia and Luna, were crumpled to the sides of the halls and burned in piles that reeked of oil. Flags of Equestria were replaced by those that carried the curved, Cervidae horns over a red backdrop. The once great window panes that proudly shone with the history of Equestria's greatest triumphs were melted or shattered across the floor.

Where the twin thrones for the Royal Sisters stood, a group of invaders had situated themselves, lost in the throes of their carnal pleasure. In their midst were a group of struggling mares, fighting their captors to no avail, as the two unicorn mares had their horns severed, whilst the pegasi had their wings bound.

A mix of semen, tears, and blood stained the once pristine marble below the group, the air filled with the scent of sex and the muffled screams of mares of all professions.

Today, Equestria's fall had arrived.

Across the land, Caribou of great magic and might laid siege to the once formidable nation of Equestria. Mares across the country were being stripped, raped, and taught their proper places through either sheer brute force or the otherworldly magic that the Caribou Grand Elders had mastered, warping the minds of stallions everywhere to fight their female captors, and rise to true male glory.

Where the once untouchable, incorruptible ruler of the Sun, Princess Celestia herself sat, instead was a Caribou of unrivaled might and intellect. Upon his lap, naked and panting as though she were in heat, was the bitch of the Sun herself, riding the mighty cock of King Dainn.

Dainn's right hand shot up from its place on Celestia's thigh to roughly grope her left tit, squeezing it and molding it before his eyes like a prize he had so rightfully earned. The once great ruler of the Sun moaned in both pain and ecstasy from Dainn's fondling.

"You're lucky I didn't have to show you your place with my bare hands, cunt," he whispered on an especially hard thrust.

Celestia cried in pain as she felt Dainn slam into her further. Tears streamed down her face as her head ached in pain. The inhibitor atop her horn crackled as it held back Celestia's magic. The runes on it were all-too familiar to the alicorn.

"Look what we managed to find, father," another voice added.

Dainn smirked as he watched his sons drag in a crying, purple unicorn mare into the room. Her eyes locked onto Celestia as she broke down into hysterical sobs.

"Tw... Twili-AUGH!" Celestia said as Dainn slammed into her again.

"You will speak when addressed, Cunt!" He yelled before smacking her off of his lap. Dainn stood over Celestia as he stroked his length. "Now open wide, bitch, it's feeding time," he grunted before emptying his balls onto her pristine white coat.

Behind him, Dainn could hear the tearing of fabric and the choked screams of Celestia's apprentice as his sons went to town on the mare's throat. "By the Gods, she's a tight one! You'd think this cunt never took it before!"

The King of the Caribou stood proudly over his accomplishments thus far. Celestia lay at his hooves, coated in his sperm, his sons have taken their prize of Celestia's finest bitch, and Equestria is on the brink of becoming the revolution for male superiority everywhere.

This would be remembered as the day Dainn had changed the world for the better. He inhaled deeply, savoring the aroma of his victory and his new empire.

\\\//////

Beneath the lost caves of Everfree, stood a massive set of doors. The stone constructs were etched with thousands upon thousands of soul-laced runes, which once powered the doors enough to withstand the mightiest onslaught of Tartarus' most grievous beasts.

Now, though, it stood as a flimsy wall, sapped by the Caribou sorcerers until the runes were faded and greyed out. The doors that could hold against armies barely managed to halt the wind that tunneled through. It was as weak as it was forgotten and isolated.

Thud

Demonic energy rippled between the crevices of the doors, surging forwards as it pried the doors apart. Cracks and fractures hair-lined out from the sudden burst of demonic intervention. As parts of the doors began to break away, the doors to Tartarus opened once more, and revealed ... a single demon. There was no army marching onward, no roars or shrieks to signal the end, only a single staggering demon. It towered over three meters in height on two hooves, covered head-to-hoof in thick red skin that was thicker than any armor.

At least, it would have been were it not for the gaping hole where its right arm would have been.

The Baron of Hell struggled to dredge forward, bleeding a trail as it limped on, its knees threatening to cave in from extensive damage. It clutched at its stump in an act of futility, trying to find a way to end its horrible pain.

Unfortunately for the Baron, the end was upon it.

A green blur shot forth from the ruined gates, a whirring noise accompanying its charge. It slammed into the back of the Baron's knees and sent it toppling over. Seconds later, the legs were severed by the motorized chain as the Baron pulled itself along the ground with its last limb.

The green figure walked up to the Baron's face and looked it in the eyes, reflecting its terror back at it with a transparent, golden visor before bringing up both of its fists and slamming them into the demon's eyes.

Grey matter and skull fragments exploded from the remains of the demon's skull, coating the green armor in an even fresher sheen of gore.

The figure looked up and around himself as he grunted in annoyance. Once again, he was lead out of Hell at some kind of junction between worlds. However, it wasn't entirely red, nor was it covered entirely in sand, so it wasn't his intended destination.

"I apologize for the lack of directions," the backup of Mars' Sentient Intelligence, VEGA, echoed in his helmet. "I am unfamiliar with any of the maps that lay outside of recently explored areas. As I do not have access to any UAC equipment in this state, I-"

The Doom Guy silenced his companion with a swift knock to his own helmet.

"I would advise against such means of intervention, sir. You would likely bring more harm to yourself than to me in long-term damage."

Doom Guy grunted in annoyance again.

Without warning, his HUD began to blink and highlight a trail into the... it was colored like his armor, except more vibrant. Whatever it was, it made him angrier just looking at it.

"I'm detecting surges of Argent energy across multiple channels. It is likely that there is a Demonic incursion in this dimension. My scanners are reading a minimum of several hundred in close vicinity. Will you intervene?" VEGA asked.

The Doom Guy responded by bringing out his Combat Shotgun and pumping it.

\\\//////

"AAAAHHHHH!!!"

Dainn turned to see one of his Archmagus, Carmine, burst through the doors to the Throne Room, screaming in agony as he clutched his horns.

"Carmine, what are you doing?" Dainn asked.

"THE SLAYER! HE IS UPON US!" he yelled, red flashing in his eyes. "HE HAS COME FOR US! HE WILL BRING RUIN AND DEATH TO EVERYTHING WE HAVE ACCOMPLISHED! HE WILL SHOW NO MERCY! HE WILL SPARE NONE! THE WORLD WILL DROWN IN OUR BLOOD AS HE... AS HE... AAAAAAAAAAAAAAAAAAGGGGHHHHH!!!"

Several other Magi began screaming in agony, the runic symbols on their bodies glowing with rage as they burned their hides. Carmine pulled out his dagger and brought it to his neck.

"GODS HAVE NO MERCY! WE ARE ABANDONED! NOTHING WILL STOP HIM!" he shouted before plunging the blade into his throat and jerking it to the side to split his neck open.

The Magi before Dainn repeated the action, executing themselves as their screams were drowned out by those in the streets, witnessing the mass suicide as the battle for Canterlot raged on outside.

Dainn watched in horror as his greatest line of control over Equestria suddenly killed themselves en mass, screaming of the Slayer.

'The... Slayer?' Dainn thought as he heard the shrieks of the whores.

There was something about this world that was familiar to the Doom Marine. The colors were disgustingly vivid, and the tall brown things around him wanted him to bring out the Chainsaw again (which VEGA managed to help him fix with an Argent something or other) and cut down everything before him. However, it also felt like he was reliving some part of his past, before he went to Hell. Something... that he may have missed...

Although it was hard to tell when there were so many things to kill.

These were strange Hell-creatures, being made out of the brown stuff, but they kept getting back together, bigger and stronger, every time he tore them to pieces. It was actually pretty fun being able to kill them again and again, until it pissed him off. He pulled out a Plasma Rifle, and that was the end of that story.

Now he was reaching the end of what VEGA called a 'forest', and heard something scream. It wasn't the cry of an Imp, nor was it a shriek of a Lost Soul (thankfully). It was a singular sound, without echoes or presence. For some reason, it was a higher pitch than most of what the Doom Marine could remember, and had a hint of his favorite reaction: fear.

The Doom Marine approached the end of the canopy, and what he saw was... something.

There were about seven figures that were... he didn't want to describe them. Instead of the red hardened flesh that he was used to beating/stabbing/shooting/exploding/ripping apart, they were covered in fur. Six of them were shades of brown and had large horns on their heads and wore nothing from the waist-down. The seventh, however, was yellow and pink, and had wings. It was screaming as the others ripped its not-armor off and proceeded to drag it across the dirt and rape it.

The Doom Marine was familiar with scenes of Rape, as he had stumbled onto a few demons doing so in his earlier days when Hell was full of life. This was no different. They began to stroke themselves onto the screaming creature, one of them stuffing itself into the screaming one's mouth.

Doom Guy silently thanked it for shutting it up.

"I'm detecting language patterns similar to the ones in Hell. Activating Translators," VEGA announced.

Doom Guy silently cursed VEGA as he heard them talk.

"War-God, this cunt is tight!"

"Yeah, but her screams feel good on my cock!"

Doom Guy looked to his side to see a large mass of dark brown fur and blood to the side, with some knives sticking out of it. Beside the pile were tiny, crying things that were watching the scene unfold with looks of horror etched onto their tiny faces.

Bored of what these things were doing, the Doom Marine grunted and went to find another-

"Angel Bunny!" the yellow one screamed.

Bunny

Doom Guy froze. Something about that word was... familiar with him. It brought back pain and... something else he only felt when he ripped an Imp in half.

Curious of the connection, Doom Guy turned to see one of the brown things holding a-

Daisy

Time stopped for the Doom Marine.

Pain and happiness alike flooded his mind as visions of a white bunny, prancing across a meadow flashed before his eyes. He watched as she skipped about the flowers and twitched her little nose with those shining blue eyes, pleading the same question as the bunny before him did.

Why?

"Please, no!" the yellow one cried out as the brown one before her shook the bunny.

"Little cocksucker things he can insult me by pelting me with carrots!? I'll fucking show you!"

The brown one grabbed the bunny's head and snapped it around with a sickening crack.

And the world went red.

Rip and Tear

Doom Guy watched with a frozen heart as the bunny was released carelessly, and flopped onto the ground with a blank face, the yellow one screaming out his name.

"Angeeeeeel!"

Rip and Tear

Something in Doom Guy's mind began to burn with an intensity that he had not felt for a thousand years. Memories of the Demons invading Earth, destroying cities, and Daisy...

RIP AND TEAR!!!

Doom Guy pulled out his Shotgun and charged at them.

Fluttershy wept in pain and sorrow as she watched Angel's lifeless body fall to the ground, the Caribou behind her mercilessly pounding into her once virgin behind. She felt numb at his actions, only able to cry at the loss of life around her. Harry lay dead and skinned, Margaret and the other birds were thrown into the river, and now Angel was dead, all trying to save her. She wasn't worth this loss. She didn't want them to die like this. She didn't want to lose herself like this. She prayed for anypony, anyone, anything, to stop this.

"RRRRRRRRAAAAAAAAAAAAAAAAGGGHHH!!!!!!"

*CLICK-CLICK

*BOOM

One of the Caribou by Harry's remains suddenly exploded into a shower of gore as a massive figure in green blood-stained armor charged forth, holding a weapon with a smoking barrel.

One of the Caribou tried to react, but it was already upon him. It grabbed the Caribou's right arm by the wrist and pulled. Flesh and bone tore as the arm was ripped straight from his socket. Before he had a chance to scream, the monster swung the arm right at his head, smashing it inwards and embedding the arm elbow-first into his face.

It stood there and glared sheer rage into the other four Caribou, before it pumped the underside of its weapon and charged once more.

The third Caribou managed to pull out his hammer, but wasn't able to do much else as the beast used its momentum to slam its foot into his knee. The Caribou cried out in agony as his leg crumpled underneath the metal-clad monster before another thundering burst from its weapon blew his head into a red mist.

Another pump and the monster turned around to be met with the blunt end of a warhammer. When it impacted its head, however, the stone broke apart into dust on impact. The monster replied by grabbing the Caribou by an antler and holding him at least a foot off the ground as it dropped the weapon. The beast brought its fist into the Caribou's jaw three times, caving in his muzzle and skull through sheer brute force.

It dropped the corpse without hesitation and turned to the last two, craning its neck and letting out a crack. It stomped its way forward and Fluttershy suddenly felt the Caribou behind her pull out as she was pushed before it.

"Take the bitch! Please spare us!" he cried.

Fluttershy watched in horror as it approached her, cracking its knuckles as it...

... stepped right over her.

Fluttershy watched on in horror as the monster launched itself onto the last two, grabbing them both by their necks and slamming their heads into each other, repeating the action faster and faster, sending bits of blood, skull and grey matter flying everywhere. Once they were nothing more than bloody messes, it dropped the corpses onto the ground and looked right down at her.

The pegasus tried to cover herself in any way as to not appear as vulnerable as she'll ever be, but the thing before her seemed... immediately different. It didn't look at her, it was looking at Angel's body. It walked right past her and, with a delicate hand, picked up Angel and slowly slid its fingers down Angel's eyes, closing them.

"Who... w-what are you?" she managed.

It put down Angel, looked at her, and uttered one word that would echo throughout the world.

"Doom."
