Mission T1. The Princess of Friendship Part 2

Twilight awoke yet again in the same demonic room. The agony of the procedure still haunted her, but what she stared down at made her realize the purpose of the machine.

Both her hooves were replaced with similarly shaped metallic nubs. Lines across the sheets and hard welds connected the device together. Glowing purple energy flowed in sections of light on the prosthetic. She focused her magic only a moment, her horn not glowing at all when she saw an energy blade schwoom out of the metal hoof.

She could feel the dangerous heat of it from a couple centimeters away, crackling with violet. Her other replacement hoof could do the same, her commanding it to jut out as well. Her weapons hummed with intense magic, ready to be utilized.

She looked to the upper walls, staring at all the names which surrounded her. If she was going to save them, she would have to properly pass the trial. Seeing as she couldn’t walk with her Hoof-Blades activated, she hovered on her wings, flying towards the skull-tipped switch and pulling it.

Twilight, recalling the positions of the first two demons, spun around and dashed at the spawning Imp. Just as it jumped out of the portal, she jammed her right Hoof-Blade through the chest of the monster, slamming it into the wall. She forced the second Hoof-Blade through the beast’s face, its head contorting and it croaking in death.

She removed the blades like a knife through butter, before ducking under the sweeping blade of an approaching Gargoyle. Twilight flew away from the beast, charging her horn to blast a wave of assaulting magic at the demon.

It roared in agony, lighting ablaze with light pink flame. It was stunned, scampering around on the ground and waving its wings. Before it could gather itself, she flapped over and swiped the Hoof-Blade through the monster’s neck, lobbing the head off with ease. Its fading screams didn’t bother her a bit, her mind stuck on the pained hollers of her people that they caused.

She looked around with a furious look, wings still batting the air angrily. Four portals surrounded her, two more Gargoyles and two more Imps clambering out in the corners of the arena. Twilight flew out of the way of a quickly encroaching fireball, dodging a gunk of acidic spit from a Gargoyle.

Twilight flew towards one of the Gargoyles with fervor, grabbing the neck of the demon and lifting it off the ground with her. Whatever the device had done had increased her strength drastically as she tossed the much larger being across the room. It collided with an Imp, the two beasts screeching as they barged into the wall with their back.

Before they could get back up, she charged a railing energy blast. She warmed up enough force in the beam to collateral straight through the two lined up demons, blasting the small head off the Gargoyle and shooting through the heart of the Imp. They wailed one last screech of agony before Twilight flew furiously after the two remaining fodder.

At first the energy beam was a light pink, her usual aura color. But the more hot and piercing it grew, it shifted into a blazing dark purple that matched the intense energy she had been injected with earlier.

She propelled another piercing beam through the chest of the remaining Gargoyle, the demon stumbling back. Her blasts were much more powerful now thanks to the new, strange magic flowing through her veins. Before it felt more blunt, but now they sliced through enemies like some sort of cannon.

It looked down at the hole in its chest, its heart pumping furiously. The rib cage was blown through before the demon collapsed to the floor dead.

Twilight shouted in pain at the feeling of an intense weight bearing on her. She fell to the ground, feeling a patch of feathers and flesh be removed from one of her wings before she bucked off the sneaky Imp and blasted it with a lighter bout of energy.

She felt the exposed hide burn with the hellfire tipped clawmark as she rose to her hooves and sliced the throat of the staggering Imp. Twilight attempted to take flight, finding it unbalanced and too painful with her immobilized wing.

The alicorn felt ill at the sound of the walls around her lowering. The building shook as the brick crumbled to reveal the noise of more roaring beasts and snarling monsters. Her ears reared at the sight of a screaming Pinky that presented itself ahead of the crumbled walls.

It charged furiously, the demon twice her size as it trampled her down before she could even react. The last thing she saw was her limbs tearing away from her body, ribs being crushed in and the sight of liters of blood flying from her.

She awoke with a start, feeling the restricting robotic arms of the EPD. The panel in front of her read in her mind again with its echoing, monotone voice.

“Results acquired. Processing… faster wing speed required.” it explained.

Twilight reared her head to look at another pair of metallic arms clamping tightly around the base of her wings. She clenched her teeth, feeling her stomach churn at the sound of roaring buzzsaws. She turned her head away from them, sending the alicorn defining limbs a silent farewell before she squirmed in the suffering induced by the wing deducting blades.

She shut her eyes, tears leaking as Twilight held back any screams of pain. Her metal hooves shook violently and the occasional gasp or quick scream echoed through the room. Eventually, she heard the thuds of her feathery wings crashing into the ground.

The princess grunted, sobbing a tear or two as the platforms where the new replacements would be created were raised. The melted metal formed sections of the new wings, being set on another table on her left where the advanced replacements would be built.

She shut her eyes, searching for rest. All the pain had brought wear to her consciousness. She let her head go limp, closing her eyes gently as the arms welded and soldered the technology together.

Twilight’s eyes flung open. The piercing jabs of needles being stuck into the base of where her wings used to be. The device implanted tiny neurological connectors, before lifting the new wings off the table. They were made of many different layers of gray steel, hunked together with unlit lights on the ends of the metal wings. At the backof the prosthetics were a pair of jet-like devices.

She turned to watch as the arms placed the wings into the bases, the prongs on them digging into her bone and flesh. She watched the dim feather-lights glow a bright purple with similar energy as her Hoof-Blades. Twilight shifted the metal, moving just like her old, natural wings. The alicorn flapped them gently, the metal folding between creases gently.

"New wings set. Neurological sync confirmed. Preparing trial number three."

With a blink, she awoke back in the hellish realm. She turned, flexing her wings. Twilight’s back was still cursed with the pain of the operation, but the new glowing pair shimmered wonderfully. The princess felt a wave of disturbance at her thoughts of death to the demons with this new device. Was this the Equestrian way? She looked back down at the ground to her new hooves. Would Celestia want this?

She shook her head, fury filling her mind at the reminder of her friends. If she doesn't do this, no pony would survive, not even Celestia. A growl rose from her throat as she imagined the horrors being committed on her friend and people.

Twilight could imagine innocent Fluttershy being ripped to shreds by Imps. Pinkie Pie getting her tongue sliced away by a Gargoyle. Rainbow Dash getting her wings torn off by the strong arms of a Hell Knight. Rarity's gorgeous coat melted away, the pony turning into a dragging Zombie. The sight of Applejack being immobilized, legs snapping from terrible torture devices. All these visions and imaginated nightmares held echoing screams of her friends.

But one she didn't need to imagine glowed in her mind like an ever-present lightbulb. It was all still so fresh. The gruesome crack from Spike's tiny body, the cruel glare of Kronos. It repeated in her mind every moment, her conscience refusing to let her forget. She lifted her metal hoof, the purple energy blade shooting out.

Twilight consumed the switch in her aura, pulling it. She immediately spun, hovering on her flying metal, grabbing the teleporting Imp by the throat. The horrified scream was music to her, before she plunged the energy dagger into the beast's chest, throwing it to the ground and blasting its head off with a beam.

She predicted the approaching Gargoyle. Twilight unsheathed her other blade, charging at the demon with all the speed her wings could fly. She cleared the large room in a little over a second, impaling the Gargoyle into the wall. One blade was stuck in its mouth right between the mandibles, the other right through its heart.

Twilight watched blood pour from the demon's body with cruelty, a psychotic laugh between her breaths before letting the body drop to the ground. She watched as the other four demons, two Imps and two Gargoyles, jumped into the arena, flinging fireballs and acidic spit right at the still alicorn.

One of the demon's exclaimed in surprise as it was teleported, the Gargoyle flashing in front of Twilight. It was lifted off the ground, hoof around its neck as she hovered on wings. The powerful energy that the EPD injected into her provided unusual levels of strength. The many projectiles burned and melted the chitin of the Gargoyle. With a satisfied grunt of the maneuver succeeding, she plunged an energy dagger through its chest and hurled it at the closest Imp.

The Imp fell to the ground from the weight of the fellow demon's corpse. As it was stuck on the ground, Twilight flew as quick she could to slam her hooves through its head. Its scream was cut off. She lifted a gray hoof, watching the blood drip off of it for only a moment.

She felt a fireball suddenly scorch her flank, Twilight screaming in scornful pain. The alicorn flew to the center of the room, spotting the Imp culprit.

She shot the Imp's head away with a purple magic shot, turning and decapitating the Gargoyle that was trying to sneak up on her. Hearing their wings was trivial. Twilight caught her breath, preparing for the next wave of demons. The alicorn made sure to keep above the ground, knowing what demons greeted her.

Twilight chuffed with amusement as the four Pinkies that crushed her all rammed straight into each other’s faces. She lifted her Hoof-Blades directing her flight path downward. The pony drilled down into the back of one of the beasts. It roared in pain, collapsing to the ground as Twilight flew back up, covered in blood after diving into the guts of a demon. She spat out the viscera, shaking her head in disgust before refocusing on the three remaining stunned Pinkies.

Her horn whooped with power, unleashing a wave of magic through the tail of another Pinky, blood exploding out. In her idle flight, an intense heat blasted her fur, scorching down her hide.

She blocked the next ball of violet flame with her energy dagger. Twilight saw a familiar beast below. A duo of those purple, Imp-like demons that had attacked Fluttershy prepared another heap of fireballs. Anger roared in her chest, fizzing like a shaken soda. Prowlers, the Codex called them.

The two formerly stunned Pinkies looked up at her, trying their best to leap with their heavy and clumsy bodies. They could never reach the alicorn. Their hops were pointless. She flew out of the way of two more fireballs, the Prowlers disappearing in a cloud of purple flame.

She dispatched the two Pinkies, flying onto the back of one, stabbing it to death. The other attempted to charge her while she was atop the dead beast. Before it could make contact with the alicorn, a portal opened, the exit appearing on the horizontal side of the room. It ran out, its purely straight charge continuing. Another purple vortex appeared, teleporting it to another area of the arena, before the Pinky continued into yet another.

Twilight repeatedly sent it through dozens of portals, its velocity accelerating faster and faster. Its screaming war cry turned from rage to terror as it realized it couldn't stop running. Finally, she planted the final portal right in front of the wall. The demon crashed into it, the ground shaking. Its body was torn and demolished from the absurd speed it had met the wall at. Blood crackled out of the Pinky's crushed corpse, its own natural armor dug into its brain matter.

The alicorn heard the Prowler poof behind her, raking its gnarly claws down her back. Twilight threw her wing, screaming in agony. No further attacks occurred, the dead body of the Prowler falling to the floor. She turned, curious how it had been killed. Then she glanced at the blood dripping from her wing. The sharp limbs could slice nearly as well as her blades.

She ducked under a flame ball meant for her, glaring at the demon with the fury of a hundred stars. It was about to sculk away, but it was gripped in her magic, being lifted off its feet. Twilight slowly walked towards the last demon, her loud clanking hooves echoing through the room. She watched as the immobile demon roared in fear, trying to break free. It wailed like a foal.

She lowered her horn to it, a wall of magic blades appearing in front of the Prowler. Just like this demon had done to Fluttershy, it would be met with thousands of lethal cuts. Blood rained from the demon as the sharp magic was sent forth, agonizing roars filling the room that made Twilight’s ears twitch with satisfaction.

It felt like ages had passed as the legion of magic slices continued. Twilight felt a moment of disgust as she realized that, for a second, she was beginning to enjoy its screams. The beast roaring in agony was beginning to soothe her of guilt.

When the blades cleared, all that remained in her magical grasp was the skeleton of the Prowler. Twilight dropped it, bones clanging to the ground. Her legs wobbled, the pony collapsing to the ground with weakness. Her horn burned, sizzling and steaming with use. She gasped for breath on the floor, slowly climbing to her hooves.

The pony had several patches of fur burnt away, the hide beneath burned away to reveal flesh. A heavily bleeding scratch sat on her back and she was covered in sizzling demon blood. When she finally stood, she saw the walls of the arena fall away, revealing a demonic wasteland outside. It was dark brown and red, giant skeletons dotting the desolate place.

The alicorn sighed, worried that she'd not have enough magic to finish the trial. She had wasted much of it on the last two encounters. Twilight flew cautiously out the room. She kept her eyes widened for any demons. She swiftly spotted a green, pony-sized ball of hurdling flame. Twilight dodged it, flying around and spotting the Baron of Hell that confronted her.

Twilight dashed past it, slicing a duo of her wing and Hoof-Blade through its shoulder. The Baron tried to grab the Alicorn as she passed by, missing her. Twilight dodged more attempts of grabbing and launched fireballs. The alicorn dodged each attack, getting cuts and slices in. She was like a fly to the huge demon. It wasn't so effective, but on occasion the Baron groaned in pain from the minor cuts.

A plan formed in her mind as she made another cutting dash, rushing back towards one of the beast's legs. She diced through one of the ankles of the Baron, blood spewing onto the hellish ground. Now behind it, she charged into its back, forcing it to the ash and bone covered floor. Twilight lifted a hoof, driving the energy blade through its nape. She saw the burning energy cut through its spine with ease, the demon going limp with a pathetic roar.

"AAAAAAAAHHH!" Twilight jumped at the screech as it rapidly approached. She was knocked off her hooves as the Lost Soul tore into her flank, bone fragments causing numerous bleeds. The fire burned at her cutie mark, sizzling the emblem away.

She was tossed away off the Baron. The purple pony laid on the ground, too weak to stand. Twilight gently lifted her head, heavy with weakness. She stared at her lack of cutie mark on her left flank, the star actively burning out, the colored fur wisping into smoke. Her wings and blades flickered as she looked up at the culprit. It shocked her when the huge, round demon that had struck her presented itself so near.

Her friends flashed in her mind again as the Pain Elemental gaped its mouth to devour Twilight. Her weak breaths for air quickened, anger seeping through each exhale. Rage clouded her mind as she lifted her wings, the jet boosters activating. A growl busted through her lips, like a parasite through flesh. It sounded like a million centipedes crawling up her throat. Pure, visceral hatred seeped out before she propelled into the mouth of the monster.

Before it could even attempt to swallow her, she jetted through the back of the Pain Elemental, drilling through flesh and bone with her blades and wings. Twilight dove out the back of the dead demon, soaring high above the field in search of more threats. Looking below, she spotted a Mancubus gawking at the brutal murder of its ally. Before it could even trace Twilight, she propelled downward, blades first. She dove straight through the head of the demon, blood spewing as she flew back out the top of the demon.

Twilight was now covered in more blood than fur as she glared viciously at the remaining monster. A tall Cyberdemon, pointing its cannon straight at her. Lethal lasers whirred toward the alicorn before launching legions of missiles. The alicorn landed on the arm of the monster. It stared at her a moment with brutish confusion before she drove a dagger through the arm cannon of the Tyrant.

Sparks flew as the energy blades drove through the wire and metal of the missile launcher. She twisted her blade, aiming the arm-mounted weapon right at its face. It screamed in effort, Twilight gnashing her teeth to fight against its strength. Her enhanced energies which changed her aura's color bright purple boosted her force, but the main drive was the rage that fueled her.

The Cyberdemon attempted to wave its other arm at Twilight, each time the hand got zapped by the remaining spells her low energy could produce. A great pain but no major damage from the small purple beams. The cannon charged beneath her hooves. The alicorn could feel the weapon pulse as rockets were loaded. The wave of lasers burnt away patches of flesh from its face. The roars of the demon filled the clearing as its head was blown away by a gang of rockets.

The self-killing Cyberdemon collapsed to the ground, Twilight taking flight as it quaked the arena. Slowly, she settled to the floor. Twilight scanned across the clearing. The corpses of the large enemies surrounded her, and the only noise that accompanied the buffeting wind was the sound of blood and viscera dripping from the princess’ fur. The trial was over.

Her breathing slowed gently, the alicorn slowly got off her hooves. She laid down, staring at the sky. Her anger gently steadied, transforming to solemn. Tears gently drifted down her cheeks, washing away the blood that stood in its wake.

She woke back up to the waking world with wet eyes still. Twilight hoped this was the last one as the buzzsaw noise descended upon her head, directing right to her horn.

~

The pony that was released from the machine was now sealed in a cold, metallic suit of unimaginably strong armor. Her friendly violet fur was welded shut within the confines of the emotionless armor. The gray colored, monochrome suit was only punctuated with a dark purple glow shimmering between cracks.

The metal hugged each body part to near perfection, nimble and light yet difficult to pierce. The only object that poked from the sleek form of the metal were tubes of the purple magic that now replaced her much brighter violet. Her tail was absent, and all that remained of her mane were steel frills folding up from the nape, edged with the same lethal magic.

She stretched her wings, now replaced with the metal pair tipped with the same slicing energy, jets readied at the back of them. Her peaceful and fluffy wings were now sails of murder. The empty space where her horn resided filled with a holographic variant, glowing in magical brightness even more intense than her organic one would shine.

Finally, the soulless and emotionless helmet flickered with light. The only sign of a facial feature on the armored pony’s head being a visor for the alicorn to gaze through, glowing much like the rest of her armor in more dark purple. The rigidly shaped helmet gazed down at her mechanical hoof, lifting it to activate her Hoof-Blade, a shard of shimmering magic extended from the wrist of her hoof.

The only indication that it was Twilight Sparkle in the high-tech suit was the stamped copy of her Cutie Mark residing on her hip, where it would be under the suit. Though, even the colorful emblem was flaky and worn on the gray metal. The ink that was utilized on it must have been aged greatly.

She gazed at the HUD displayed in her visor. A blue bar sat at the bottom left with a green one above it. The number 150 was plastered over the blue, 100 over the green. The words “health” and “armor” in upper case sat to the left of them. 100 armor, 150 health. At the bottom right sat a violet bar, the word magic neighboring it. It was filled completely. The HUD was thankfully translated to modern Ponish.

“Are you ready, Princess?” the Praeleanthor queried.

She lifted the Blade near her helmet, gazing at it slowly before finally speaking up. “Yes.”

NotAnEditor пожалуйста ответьте на мой вопрос хорошо я буду ждать вашего ответа!?

Finally managed to catch up.

I really like the worldbuilding you did here. With any luck, when all ends, Twilight will still be at peace on Equestria. Would be interesting if Discord gave Twilight a better set of weapons and armor.

And I want to see the Slayer face when he learns Discord enjoys his tea afternoons with Fluttershy. The look on his face as he tries to comprehend what is happening will be awesome.

Then Slayer Twilight invites him for a picnic.

Thanks for reading the story! This whole project is just me stretching my writing muscles and see if I have the capacity and patience to produce a full novel. I had so many ideas about how a MLP and DOOM world would work. I don't really like it when in fanfictions its just "Oh, its a different dimension!" so I decided to do something different. To plaster MLP into the world of DOOM as a former Sentinel nation and an undercover gateway territory for Hell to use to get back to power after the DLC ending. I'm glad you enjoy it.

The idea worked out. It is plausible. One thing I found strange was tgat bit on the beginning, about Davoth *letting* the Slayer win, so he could be resurrectedcon Equestria

The Archdemons motives are reasonable., and it is refreshing they dont go stupid evil. I will keep reading new chapters as they release.

Also, are you going to let the Slayer meet Angel? Would be interesting if Angel followed the meme about being the Beast of Caerbannog, from Monty Python.

[Calmflame]

Despite what has happened to Twighlight, I would like to think that the slayer would still be able to beat her.

[NotAnEditor]

11516591
When is that mentioned? I think you may be misinterpreting Davoth commanding the arch-demons to invade Equestria if he died as a backup plan. Not the main idea.

[I like burguers]

11516656
This passage of the chapet "Codex/Dread legion" may be understood like that;

Davoth commanded the two to form the Dread Legion, the primary invading force to be sent to Equestria. The plan was that the Dark Lord was to give himself up to the Slayer and let him be encased in Ingmore Sanctum. Without him, it’d be a cakewalk.

"Give himself" here can be understood as allowing himself to be defeated so the Slayer wins, and ends up locked on the Ingmore Sanctum. Equestria is invaded, and Davoth is resurrected, without the danger of the Slayer

[NotAnEditor]

11516687
Oh! Okay, weird. Yeah, I often workshop things in the actual chapters and forget to change them in the Codexes.

[Wargod642]

Slayer Twilight, lets GO!
