Prototype meets TCB

It has been 15 years since the barrier of Equestria appeared, now all of Humanity is gone.

I am not gone, I am not Pony or Human. I am something different, me and my fellow species will turn Humanity, and Ponity into ourselves.

Matthew Brewer stood atop of the Empire State building, looking out at the encroaching Equestrian barrier, the shimmering blue barrier brought back memories he wished would stay down forever, things no man should've done. He fell foward, to end his life, and closed his eyes, to dwell in his memories.

A thin, wiry man walked through the streets, his short, spiked black hair was covered by a hooded jacket, the jacket was covered by a leather jacket with the three horns of Odin on the back, colored red. He was heading back to his home, to see if his wife and child were still human, as the PER did a bombing run with serum. He went to the door of his apartment, locked, he lifted his foot up, and kicked. Breaking the door, he walked through the gaping hole, and nearly dropped in shock.

His Wife, lay on the floor, caught in between Pony and Human form, he checked her heartbeat.... dead. His tears streamed out of his eyes, the warm, salty fluid stung his wounds were infected had slashed him. He cradled his lover close to his chest, sobs drilling out the cries of pain around him, as converted humans were took over by Celestia's will. " I love you Selena, I'm sorry, I should've never have left you alone for a day." The last word was high and shrill, as another pack of sobs echoed from his throat. He set his wife down gently, tears pooling on her cold body. He stormed around his apartment looking for his daughter. He busted open his daughter's door, looking for his infant daughter. He felt a large burst of relief, as his little baby Sylvia was still alive.

The wind turned warm, and the air began to smell of blood and flame, metal long rusted, he opened his eyes, only to be assaulted by the stinging winds. He closed his eyes again, and allowed his memories to finish playing in his head.

He sped down the freeway, Sylvia in a car-seat beside him, he was fleeing from the wave of infected, former people corrupted by the Mercer virus, started by Alex Mercer. A ragged, humanoid form dropped in front of the car, hitting the speeding car in the windshield, startling Matthew, his vehicle steered off course and crashed into the guard rail. He caught his breath and looked for Sylvia, she was gone, her window was broken.

He opened his eyes again, seeing the rapidly approaching ground, and Mercer. He couldn't do anything about Mercer walking right underneath where he would splatter, and raising a arm-turned-blade to spear him as he fell down. SHUNK! Matthew was stabbed by Alex, blood running from his mouth in a small river, Alex's strain of the virus merging with his body. Mercer pulled the blade out, slang Matthew onto the ground, and shape shifted into a pony, then walked through the barrier.

Matthew put his hand over the massive, gaping hole in his stomach, and promptly fell down, silent screams shaking his body, as for without a diphagram, he couldn't breathe. In his dying vision, he saw hooves, coming towards him. He was turned onto his back, and serum dumped upon the gaping hole in his body.

He promptly passed out, from the severe pain caused by the Serum coming into contact with his flesh, steam rose off his body. His body twisted, shrunk, and morphed as the Serum transformed him into a pony, however, the Mercer Virus was protecting his mind, keeping the serum away from the parts that allowed him to feel Anger, Hate, Vengeance, Pain, and sadness.

Soon, a Jet Black coated, Blood-red maned Earth Pony lay on the street, the Three Horns of Odin, colored the same red as his mane, was his cutie mark, blood red eyes stared empty at the ash-filled sky.

" NO NO NO NO!" Yelled a tearful Matthew, kicking open the car door and looking around for his daughter. " SYLVIA!" He shouted, the wailing cry of an infant sounded, his infant's wailing. " NONONONONO FUCK!" Matthew ran towards the sound of his daughter crying, and found the infant wrapped up in a blanket, and held in the arms of a individual in a leather jacket and hoodie. " Thank you, thank you." He reached out to take his daughter, and keep her in his safe hold. But the individual, turned and stared at Matthew. A frown plastered on his face, Matthew soon got angry, he pulled out a pistol from under his jacket and pointed it at the hooded man. " Give me my daughter now." He said, in voice that dripped with homicidal venom.

" I'm not, I'm saving her from Celestia, no matter what your opinion is, I'm not going to let some Batshit-insane royal fuck, murder a perfectly capable young child." After his small speech the hooded figure revealed his face, Mercer, then the Evolved man jumped away, Sylvia cradled in one of his arms.

Matthew dropped to the ground, tears forming in his eyes. " FUUUUUUUUUUUUUUUUUUUUUUUUUUCK! MERCER YOU FUCKING ASS EATING SHIT! I'M GOING TO GET A SAW, AND SHOVE IT UP YOUR ASS SO FAR, .... SO FAR... IT"s GOING TO BE REALLY FUCKING UP THERE!"  Matthew screamed in rage, he threw the pistol to the ground, a stray bullet fired from the gun as it impacted the concrete.

He picked himself up and ran after Mercer, knowing that he could never catch up to him, but he would try, even if he died trying, he would murder any selfish bastard who got in his way. He would make a Pony look like a Modern-Art masterpiece if they tried to stop him. The only thing he could feel, the only thing he could register in his mind was rage.

The large, pillars of infected biomass vanished as the barrier consumed them, the buildings crumbling into dust as the barrier pushed them over like child's toys. He stared at the now blue sky, he wasn't peaceful like most Newfoals after his conversion, in fact he was quite the opposite, he was Very Fucking Angry.

Displeasure

Matthew Brewer picked himself up unsteadily, thick blocks of keratin as hands and feet, and being quadrupedal, was not in the man's instinct or knowledge. Then, realization slapped him in face and socked him in the groin... he... was...a....fucking...Eathy pony. He exploded in rage, filthy thoughts echoing in his head, shaking his soul to the very core. His hooves pounded the ground, earth splitting under the massive strength of his hooves impacting the soil. Heavy pants resounded through the grassland, wisps of Mercer Virus Biomass swarmed across him, and soon the pony was no longer a pony,  Matthew was human again! " What the fuck?" Deadpanned Matthew as he looked over himself, joy seeping into his head from the sudden realization  , that he could become human again.

" Wait, can I ?" Matthew wondered as he tried the theory that suddenly popped it's way into his head, as he suspected, it worked! He could transform in between his pony and human form, he transformed into pony form, and began to gallop away, looking for the pony that transformed him. As if on cue, his vision went red, and a white pulse went across the ground. Making Matthew clutch his head, " What the hell, am I see goddamn sonar ?" He willed for the sonar-like vision to come back, and it did just that. Except this time, the sonar came back to him, the man put two and two together and guessed that the object the sonar was bouncing off of. Was the pony that converted him, he galloped faster to the location, going nearly 70 MPH, much to Matthew's thrill, while using his sonar vision.

He soon found his target, inside a small town by the name of Garden Gait, apparently near Canterlot, he galloped into the small town, sonar vision going off, bringing him closer to his target, untill he finally saw the pony walking alongside a mare, on the sidewalk.

Hmmm, must be that asswipe's bitch, I'll make her suffer too. Matthew, testing his powers, jumped up, over the couple, and landed in front of them, creating small cracks in the concrete where he landed.

" Oh, hey, hello there! You feeling great now, because I'm the one who- HAUK!" The last word was cut out as Matthew's hand shot out, and grabbed the stallion by the throat, the other hand smashed down upon the mare's head, caving the skull in, and causing the eyeballs to pop out, trailing nerves and blood behind them, her crumpled body fell to the ground, blood pouring out of her eye sockets. The stallion began to cry, sobs cut off by the strong hand grabbing his throat.

" What the fuck is your name ?" Demanded Matthew, words dripping with venom, seeding fear within the Stallion.

" P-p-p-pepper ssss-s-s-s-s-auce." The yellow coated Unicorn croaked, gasping for air.

" Good, now I'm going to take that lantern post over there, shove it up your ass, and cut your throat till you look like a fucking cherry Popsicle." Matthew stormed over to the lantern post, Pepper sauce still gripped within his hands. The angry man ripped the pole out of the ground, threw the lantern off, and held it upright between his feet. He then grabbed Pepper Dance, and positioned the stallions asshole right above the pole, and threw him down upon it.

The unicorn screamed in pain, but was soon cut off as the pole speared through his intestines, went through his stomach, went up his esophagus, and came out his mouth, jamming into the roof of his mouth. His entire body was filled with agony, then Matthew slit the Stallions throat, and cut the back of his neck to shreds, causing blood to pour all over his body, untill he was completely red.

Matthew walked away from the town, ponies looking shocked and sick at the event that had happened, vomit went flying, the iron smell and taste of blood ran through the air, it's red tendril's filling the airway's of all. Nopony chased after Matthew, scared that the man would do the same, or worse to them.

As Matthew walked away, he looked at the pony impaled on the pole, still clutched in his hand, he lifted the body to his mouth like a Popsicle, and began to eat, big, meaty chunks of raw flesh from the stallion. " Hmmm, tastes like cherry." Matthew thought to himself, strong teeth and jaws cutting through the tough flesh, as if it were made of soft fruit.

Princess Celestia sat upon her throne, looking out upon the great hall of Canterlot Palace, it had been a celebration, all of Earth was consumed and now under her reign, and all Humans had been converted. Which meant more servants, and power for her, which meant she could take over Odinson's land in the far north of Equestria.

However, her short moment of joy was ended abruptly as a courier, bursted through the door, and ran for Celestia, letter held firmly within the MailColt's jaws. " Princess Celestia, urgent news from Garden Gait! A pony transformed into a human and killed two ponies. Vanilla  Cream, and Pepper dance, the human ate Pepper Dance!"

Celestia's heart filled with dread, a filthy human was in her kingdom, she could not have this. " What does this human look like ?"

" Well, when he was a pony, he has a jet-black coat, blood-red mane, red eyes, and some weird human-religion symbol as his cutie mark, and as a human, he's Caucasian, brown hair, grey eyes, a white hoody, with a black Leather jacket, with the same symbol as his cutie mark on the back, and blue jeans."

Celestia turned away from the courier, and walked through the halls, to find Shining Armor. This human is going to pay, I didn't waste so many pony lives to get the barrier to expand and kill humanity, only for one to come in and ruin it all. Celestia thought, face twisting into a wicked smile.

She pushed open the door to the guard barracks and shouted. " GUARDS, MEET ME AND MY SISTER IN THE GARDENS, AS SOON AS POSSIBLE! WE'VE GOT A HUMAN IN EQUESTRIA!"

Power

( Tendril demonstration and power)

Matthew walked along th grass lands, the grass beneath his shoes soon gave way to old, dried leaves. His mouth chewed the bloodied remains of Pepper Dance, the iron tang of blood wrapped around him, causing the creatures of Whitetail Woods to flee in terror, of this apex predator. His meaty popsicle, was soon running out, Pepper's head was all that was left upon the wooden pole, and Matthew wasted no time to sink his teeth into the Unicorn's skull. The hard bone split apart like wet cardboard as Matthew's jaws closed, then his teeth hit the brain.

Mercer Virus Biomass swarmed along the crushed head of Pepper Dance, and memories transferred into Matthew. Causing him to drop the meatsicle and clutch his head in pain, he fell onto the ground. Memories swarming into his head, however, one was more noticeable than the others, and caused him to see it, like a flashback.

A PER suited Pepper Dance raced through the Scarlet Zone, looking for Humans that had not been infected by the Mercer Virus, infected human were 'purified' as the ponies put it, they killed the infected, then poured serum onto them, bringing them back from the dead, whether or not if they wanted to come back. Souls screamed in torment, as they were torn from their families and friends from the afterlife, and forced into the world again. Their souls rejected the bodies, causing a week of pain untill Celestia trapped the soul within the pony body.

An apartment door was kicked in, Pepper Dance and other members poured in, Matthew's wife turned around in shock, and was promptly shot by a white-coated, light-brown maned stallion. The serum pellet tore a hole in Selena's chest, causing her to fall to the ground, her hand clutching her now torn open chest, blood pooled out in masses, and she shrieked in the utmost agony as the serum started to transform her.

" Nice shot Blueblood, no wonder they elected you as head chief of the PER!" said Pepperdance.

Pepperdance stood over a bloody Matthew, the man's arms were now made of Mercer Virus Biomass, and instead of hands, were crude, three-fingered hands. Pepperdance quickly got a serum-vial and poured it upon the man, determined to save the pony trapped within this cruel, filthy being. Much to his relief the transformation was successful, and the yellow stallion trotted away.

The flashback ended, leaving Matthew on his knees, heavy, ragged breathes shook himself to his core, his arms began to shift into MVB, his hands soon shifted into the crude-three fingered form that he had seen in that weird flashback. He picked himself back up, shaking from the sheer amount of anger that flowed through him. " Blueblood... that's the fucker's name."

" HALT HUMAN SCUM! YOU HAVE BEEN TRIALED AND FOUND GUILTY OF MURDER, TREASON, AND TRESPASSING ON EQUESTRIAN TERRITORY! SURRENDER NOW AND YOU WILL BE EX-!" The guard didn't get to finish his statement, as his head was soon torn off of his body by three, individual tendrils. The mouth was torn off from the esophagus, leaving the long, organic tube flailing around, as the lungs gasped for air, broken jugulars spurted blood in a crimson shower, torn muscle latching onto the stallion's neck.

The enraged Matthew began to do a punching motion with the Tendril Arms, tendrils shot out and ensnared guards, the long, red biomass hooking onto trees, and the ground. Causing the guards to scream in terror, before they were ripped to pieces by the sheer force of the tendrils contracting. The trees soon became Garlanded, as intestines, kidneys, stomachs, and esophagi were soon tangled, or caught within branches.

Very soon, an entire platoon of guards lay strung and dismembered at the entrance of WhiteTail Woods, and soon ponies would be coming out of the woods to return to their homes, and they would see the bodies, and they would flip the fuck out. However, Matthew did not give one tiny shit, he was going to find Blueblood, and make that motherfucker pay.

To say Celestia was displeased would be an understatement, she read the report, and almost burned it from anger. The human could shoot tendrils out of his hands, and tear ponies apart with them. It had destroyed an entire platoon in thirty seconds. This called for extreme measures, she walked out onto her balcony, and looked at the Equestrian Royal Task Force 58, ERTF58 partook in counter-terrorist, and during the conquest of Earth, extermination of humans deemed dangerous by Celestia, and all someone had to do to get marked as dangerous. Was to have a pony cry because of them, sometimes they faked to have someone killed.

" ERTF58, I know this may be short, but this human is extremely dangerous, and carries the Mercer Virus. You are cleared to use human firearms against him. If you find him, neutralize him, then bring him to me. I will have him publicly executed, and his head mounted on my fireplace. Move out."

( Short chapter, but I have been sitting for 7 hours in a plane, I am tired, and will post another, bigger chapter tomorrow.)

Blood

The moon hung high in the sky, crickets chirped a peaceful tune, a pony couple were enjoying this outside of Canterlot. " Such a beautiful night." "Yeah it's just me, you and the m-!" Both were cut off as a pair of feet trampled their windpipes, leaving them to die. " Sorry." Grumbled Matthew as he continued to run for Canterlot, hellbent on finding Blueblood.

Squad Zeta flew in the night sky, eyes trained to spot targets in the black of night, and to their dismay they saw the target, Matthew Brewer, highly-dangerous, Evolved, and murderous. They readied their various human firearms, M4's, AKs of various models, Uzis, and many others. Then they fired, sending a rain of lead at Matthew.

Matthew began to duck and dodge wildly as bullets began to fly, burying into the ground around him. Several of the bullets hit their mark, and simply reflected off, much to the amazement of both Brewer and Zeta Squad. " Huh, I am bulletproof, that's a fucking relief." Matthew then morphed his arms to have the tendril power, then a large mass of tendrils shot out of his hands. Striking a pegasus in the middle of a formation, more tendrils sprouted out of the mass and grabbed other pegasi in the group. Then the tendrils contracted, mashing the pegasi together in a massive blood explosion. Causing blood, organs, and flesh to splatter upon Brewer. " Son of a bitch! I just fucking washed." Matthew sighed and continued to run.

Meanwhile in Manehattan

A certain pony walked along a certain square, his red and black tail swished behind him, a grey hoodie was hidden underneath a leather jacket. His coat was a peachy-color, like human skin. His cutie mark was grey DNA, the pony walked up behind a random Earth-Pony stallion, and tapped him on the back of the head, implanting a Bio-Bomb into the Earth-Pony. The pony continued to walk away, while the stallion screamed in pain, causing a crowd to gather around him, asking if he was okay.

Then the tendrils sprouted out, grabbing ponies, carriages, concrete, everything they could touch. Then they contacted, smooshing all the ponies in a large area, around the stallion. Causing the square to be painted red, organs fell onto shops, broke through windows, bones went flying, and speared unfortunate individuals. Ponies soon became garlanded in intestines from the explosion. Several Mercer Virus tendrils were left behind, hooked onto the buildings.

Mercer smiled, this would be just one of many attacks. He pushed open the door to his apartment, and transformed back into a human. Looking for Sylvia, who he saved from the ponies.

Canterlot was a mess, both physically and mentally, ponies lay strung up between every sort of object, buildings were covered with gory garland, intestines wrapped around the white spires of Canterlot, Mercer Virus tendrils littered the streets. Many who survived lay crying, at what little remained of their loved ones, the tears washing away the thin layer of blood that had covered Canterlot.

ERTF58, lay scattered and strung in the Canterlot Courtyard, ripped and broken bodies hung by Mercer Virus tendrils, guts hung out of their bodies, as twisted streamers. However the sound of crows and tears, were drowned out by a massive banging. As Matthew beat upon the doors of the Canterlot Palace, his fists now transformed into massive, black and red bludgeons. The metal was bent, and well on it's way to be broken in, however none of this mattered to Matthew. Who was stained red, from the sheer amount of individuals he massacred. The door collapsed and caved in, squishing two unfortunate guard ponies into a thick, creamy paste.

Micheal Crenshaw walked down the sidewalk of Manehattan, the cool night air filled with the smell of wet pavement, however this moment of peace was cut short, as the sound of snickering and insults soon came from an alleyway, right next to Mercer's apartment.

Crenshaw heard the disturbance, and went to investigate. Truth be told he wasn't exactly concerned about Mercer's identity. He knew that he could easily defeat all of the guards that Celestia would throw at Mercer. Crenshaw turned into the alleyway, and was appalled by what he saw. Dive Onirs standing over thr corpse of another pony. "Stupid newfoal, can't believe that he actually liked them. If you ask me the more of them dead the better." A shady-eyed stallion spoke, in a stereotypical city accent.Crenshaw having heard enough to know who they were, did the most rational thing he would do to those ponies. He shifted into his human form and lunged at the lead stallion, hands wrapping around his face and neck, then pulling, snapping the leader's head clean off, his body dissapearing into Crenshaw as the Evolved consumed him. Crenshaw then lunged for the unicorn mare, grabbing and tearing her horn out, leaving a large hole to her brain, Crenshaw shoved his fist down the hole, smashing her brain, her body absorbed by Crenshaw's.

Micheal's hands formed into wicked claws, the claw's metal edges flashing the moon light into two Eath Ponies eyes, he clawed at two earth ponies, the claws headed down vertically, causing each one to fall into four slices. He then lunged at the lone pegasus, tearing of it's wings, he then smashed his hands into the hole, tendrils forming out of his hands, slashing apart the pegasus's organs, turning it's insides into a bloody paste. " You killed a pony for being different from the rest of you. You will atone for innocents deaths in blood."  The pegasus soon dissapered into Micheal, and the upset Evolved turned to the innocent victim. He squatted down and closed the poor pony's eyes. " Rest in Peace, you're in a better place now."

Micheal sighed in disappointment at the gang and what they did, he grabbed the newfoal and set him down lightly near someponine's doorstep. He then walked over to Mercer's apartment door and knocked, a piece of wood slid out from the door, and a red eye peered at Crenshaw. The piece soon slid back to it's original place, the door opened up for Crenshaw, and he soon found himself staring down at a pony Mercer.

Revenge (Short Chapter)

Mercer stared at Crenshaw above him, then transformed into his human form. " Why hello Crenshaw, I heard what you did out there. Good job." Crenshaw walked inside the noir-themed apartment. The air smelt heavily of cooked meat, obviously some poor-pony that offended Mercer.

" Well Crenshaw, I have found another evolved. Take a look." Mercer handed Crenshaw a "wanted" poster. A Caucasian male, with green eyes, and black hair. The poster read:

Name: Darwin O'shea, Human scum infected with Mercer Virus

Highly dangerous, he can shift forms with ease, however he has been found to wear a black, leather jacket, and blue jeans when he is in human form.

if you spot him, report to your nearest REA station.

Last known Location: Fillydelphia

Matthew stormed through Canterlot Palace, chasing the bastard who killed his wife. " BLUEBLOOD! NOTHING CAN SAVE YOU FROM ME! NOT PONIES, NOT WEAPONS, NOT MAGIC!" Matthew lunged, catching Blueblood right as he teleported, teleporting was horrible. Matthew felt as if he was being torn apart, cell by cell. The teleport ended, causing Matthew to throw up, the massive disorientation from the teleport making his head pound.

However, this could not stop the power of revenge, as Matthew continued to chase Blueblood, through some city. Creating a massive racket as he screamed curses at Blueblood. Scaring the pompous unicorn to run faster, for fear of being brutally killed, or worse. However this proved to be futile, as Blueblood felt a massive hand close around his throat. Then he was hoisted into the air, suffocating from the tight grip.

" You killed my wife, you remember her. You probably don't, you pro-pony fuck. You are fucking emotionally-crippled brat, your soul is worth dog-shit. Every single thing about you is ugly, so I don't think you deserve what was given to you." Matthew's left hand shot down, and tore Blueblood's junk off, the prince screamed in pain as his stallion-hood was violently removed from him. The pain was too intense for Blueblood, as every fiber of his mind was screaming in pain. Matthew dropped Blueblood, then grabbed the prince's horn. And tore it off, leaving a bloody hole straight to his brain, he then shoved Blueblood's stallion-hood into the hole. " DICKHEAD!" Yelled Matthew, as he raised Blueblood's horn and shoved it into the hole, where his stallion-hood used to be.

Blueblood screamed in pain, wishing that he was dead. Matthew, getting sick of the screams. Grabbed ahold of Blueblood's top half of his muzzle, and the bottom half. Then he tore them right off, leaving a tongue flopping around, feeling for it's mouth. Blueblood's cries became guttural as his ability to perform coherent speech was taken from him. Then Matthew grabbed the prince's tongue, and ripped it out.

Blueblood passed out in pain, but the fun wasn't over for Brewer, he willed for his Tendril power to activate, and was greeted with the familiar sight of the three fingered hands. He then began to tear Blueblood into pieces, leaving bits of him strung between the buildings of Manehattan. The blood forming a large puddle on the cobblestone street. Matthew, didn't give one shit, now that he was done with Blueblood. He was going to find Sylvia, then kill that bitch Celestia

He used his hunting vision to find Sylvia, and surprisingly, she was right next to him. In a apartment complex. Matthew kicked in the door, and jumped up the stairwell onto the correct floor. he kicked open the door and stormed in, to see Mercer and some other man. Mercer smiled and said slowly.  " Well hello there Matthew, angry I see ?"

(Notice) Hell, it's about time

I'm sorry i've abandoned this story, but, expect me to start on this little conglomerate of shit once again.
