Fall of Equestria: Bringer of Doom

"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.
