Well, here it is. The version boothnat sent me.

After I post this, there will be a poll. I won't lie that this is better, since the grammar and stuff are fixed, but which one do you prefer? Mine or this one?

The rest are boothnat's version, copied from mine with some changes. And I edited a few since apparently they made this at night. So just me fixing things.

See, boothnat didn't play the new DOOM, so me fixing what they fixed helps too. Gotta keep it close to canon, right?

I am hyped for the new Doom. So much that wanted to write fanfic out of it even before I buy the game.

There is a lack of Doom fanfics that interest me, crossover or not. I decided to make my own, as usual. And again, I add more to the RWBY Crossover section.

Put that shotgun away; I love the Doom series (even though I've only finished 3 and Resurrection of Evil and own the BFG Edition) and I intend to honor it.

There will be blood… lots of them.

As for Doomguy, I'll be taking cues from Mad Max: Fury Road by having his actions speaks louder than words.

MUCH LOUDER

Oh, and spoilers for the ending of the game… Yeah, I originally wanted to keep things ambiguous by having him forgetting whether he has experienced the story of the new game to the end or not. I decided that it's better if he did. I'm that hyped and impatient to do this.

They said that Doom 4 took so long because the original draft didn't have that "Doom feel" to it. I'm not entirely sure what the Doom Feel is, but I do hope I channeled it in this fanfic.

Anyway, as I said, spoilers for the game. So hurry the fuck up and buy the game so you can read this story.

GET PSYCHED!

DOOM: Knee-deep in the Dust

They are rage, brutal, without mercy.

But you… You will be worse.

Rip and tear, until it is done.

He awakened as a voice echoed through the chamber. The only light belonged to the demonic emblem etched in front of him. It was shaped somewhat like the letter D.

'Wait. This looks familiar.'

The man tried to move, he couldn't. His arms were chained. He tried his legs, but there was no room, the stone walls of his prison preventing all movement.

He was back in his sarcophagus.

'No...Did I ever get out?'

The man squinted, trying to remember what happened to him, but no dice. It was all a blur. He could have sworn he had gotten out before, but he could recall nothing.

Seconds later, he felt something, as if something had coiled into his very being. All of a sudden, a series of numbers popped up in front of him.

It was his helmet's Heads-up Display. The numbers were what he called his 'health bar'. It showed him how much damage he taken, and how much he could take. From the feeling on his skin, he could tell he was in a suit of armor.

His suit of armor. The Praetor suit.

He shook his head. He could think about that later, when he got out of his coffin.

The prison began to shake. He felt the container be lifted. Someone was either transporting him, or digging him out.

The question was, who... or what?

DEMONS

That word was enough. He could remember what happened when they invaded for the first time. He remembered how they tore apart his fellow warriors. His home. He remembered the one-man war he fought against every last one of them.

He remembered they killed Daisy, his pet rabbit.

They would pay for that, and every other death they caused.

But he was all alone. Something or someone had destroyed everything. Everything he fought for. Everything he cared for. Were they betrayed? Did the hellspawn use a trump card?

'I guess it dosen't matter now.'

He was all that remained of his world. Hell had taken it over a long time ago, and there was no getting it back. There was only one thing he could do. The one thing he did best. Rip and tear every single one of the fuckers.

Rip and Tear

Those words seemed familiar. They felt right.

His thoughts were interrupted when his prison jolted to a halt. He could see light between the gaps in the coffin. He strained his ears, and heard...voices.

'People, not demons.'

He was slightly relieved. At least they weren't setting up explosives. The voices were muffled, but one of them was feminine. As far he could tell, the rest were men, young men.

He could hear raised voices. Did they want to bury him again? Kill him?

'I don't think so.'

He gathered his strength, and pulled. The chains on his right wrist snapped. So did the chains on his left. Pulling the things off, he began to push on the lid.

It was heavier than he thought.

The man capable of punching apart hellspawn began to slam his fists into it. Again. Again. Again. The gap to his left widened, and his tomb brightened.

He slid it to his right, and it fell.

The light came from a star. The sun.

This wasn't hell. It felt like forever since the warmth of the sun entered his helmet. It was... comforting.

But no. He couldn't relax. Those people were still around. No doubt they planned to deal with him.

He felt time as his weapon wheel popped up. He remembered collecting many weapons. The Chaingun, two rifles—one using bullets and the other plasma rounds, shotguns, a gauss cannon, a rocket launcher… his chainsaw that's also a Great Communicator, his beautiful BFG… all gone. All he saw was his energy pistol.

He wondered where his other toys were, and where he got this one. Still, better than nothing.

He glanced at the weapon, and within miliseconds it was sitting in his hand, materializing in his right hand. Despite being trapped for so long, he was still strong enough to escape.

As he rolled away, he observed that he was on some sort of stony altars, in the middle of a green forest. Planting one foot on the ground, the man aimed his pistol at a group of eight of the strangest dressed people he had ever seen.

A few minutes ago…

"Guys, that thing's circling back… what are we gonna do?" Jaune Arc pointed to the skies, the giant Nevermore was getting closer to the group.

Weiss Schnee turned to the boy and said, "Look, there's no sense in dilly-dallying. Our objective is right in front of us."

Said objective were artifacts shaped like chess pieces. They were located in the middle of the forest and were set on a lone altar.

"She's right." Said Ruby, "Our mission is to get the artifacts and make it back to the cliffs." Weiss looked at the younger girl with a smile, which she returned with a nod. "There's no point in fighting these things."

"Run and live… that is an idea I can get behind." Jaune Arc said. Then, he and Ruby walked to the altar to aquire their objectives. Ruby decided to take the knight, and Jaune the rook, both white.

But as the boy was about to grab the piece, his foot stepped on a peculiar slab of stone; it had an odd looking rune etched onto it, its formerly red color had faded away due to time. His foot pushed it down.

Jaune stepped back with a cry, "Whoa! What was that?"

Weiss couldn't help but slam her palm into her face, "Ugh. What did you do this time?"

"I don't know! I was about to get the knight piece when—"

"I can see that." She retorted. Fantastic. She would have to deal with his antics for three whole years. Being chased by giant Grimm, dealing with an overconfident girl who was two years younger than… could this get any worse?

Oh, these eight will get one HELL of an initiation.

Pyrrha Nikos sighed as she looked at Jaune. Sure, he was cute, but he could be such a klutz. She didn't mind. However, the red haired champion some sort of red energy emanating from the altar. "Everyone… what is that?"

Ruby and Jaune turned around; the floor of the altar was shaking. The floor slowly opened to reveal a gap that slowly grew wider.

"Uh… I think we should get away." Jaune told Ruby, grabbing the white rook piece while he was at it.

"I agree." She replied. Both of them moved to their comrades as something came out of the floor.

A burst of energy emanated from the altar. It created a strong gust of wind that almost knocked the teenagers down.

Well, knocked one down. Jaune fell on his ass. Pyrrah promptly gave him a pick-me-up.

"Are you alright?" she asked him.

"Oww… I'm fine, thanks Pyrrha." He replied, grinning. If Jaune wasn't paying attention to what was happening within the altar, he would've had noticed the blush creeping up on Pyrrah's cheeks.

As he got up, the others noticed something emerging from opening. It was a rectangular box of some kind. Etched into the object were numerous glowing scratches. The energy began to fade away as the object finally came out.

The eight stared, mouths agape. Were they to remember that they had a pair of enormous Grimm after them; they'd notice that neither of them approached the future hunters and huntresses. The Nevermore was hovering away from them. The Deathstalker stopped trying to get its tail out of the mini-iceberg it was stuck in.

Whatever the object was, it made humanity's worst enemy, the unceasing tide of darkness, the greatest threat to mankind afraid.

"Is… is that a coffin?" Ruby asked, looking at her sister.

Blake Belladonna answered, "Actually, it's a sarcophagus. Coffins are usually made out of wood. This one is made out of stone."

"Well, whatever it is," Jaune added, "It's not normal. I mean, look at those marks!"

Ren took a few steps towards the sarcophagus, his childhood friend Nora clutching his hand in a vice-like grip. "Ren… I don't think you should get closer to that thing."

It was one of those rare situations where Nora was the one who tried to stop Ren. That's how terrifying the thing was.

"Nora, it's okay. I'm not going to touch it or anything… but those runes." He pointed out, "I think they resemble letters…. I don't know what the symbol on the cover means, but it could have something to do with the inhabitant."

As anxious as they were, the others, too, began to approach it. Most of them had no idea what runes were, but they knew words when they saw them.

"Whatever it is etched on the sarcophagus, it isn't in any language known on Remnant." Weiss pointed out.

"Um, guys… I don't know if you play video games," Jaune said, "But I know demonic runes when I see 'em."

Weiss scoffed. "Demonic? Really, Jaune? What's next, are you going to say that the Four Maidens are real?"

"I'm serious! Look, those letters are glowing red, and it has pentagrams here and there! I'd recognize those anywhere; I've seen them in my games and they're always bad news… Oh, man. Did I just summon an ancient demon or something? I'm too young to sell my soul…"

"Now, Jaune." Pyrrha assured, "I'm sure nothing terrible will happen to you. You're too kind to have your soul taken."

With a laugh, the boy replied, "Heh… Thanks Pyrrha. So what do we do? I don't think this is part of the initiation."

"Obviously not." Yang said. "This is waaaaay to elaborate for a prank. And if it was, wouldn't the teachers have checked this place before they send students in for initiations?"

Again, the eight stood in silence. Contemplating what to do.

"You know, as much as I want to know what's really inside," Ruby began, "Our objective is to take an artifact and make it back to the cliffs. We all got ours, and all we need to do is to get out of here."

One by one, they nodded in agreement. But before they could turn around, they heard an ominous pounding.

It was coming from the sarcophagus.

Pyrrha shifted Milo into its rifle form, and aimed it at the stone coffin. Ren did the same with his Stormflower twin machine pistols, followed by Nora who shifted Magnhild into its grenade launcher form. Jaune was last, clumsily unsheathing Crocea Mors out of its shield-sheath, before unfolding the latter into its shield form.

Yang pointed her Ember Celica shot gauntlets at the sarcophagus. Blake pointed Gambol Shroud at it as well, the chain scythe in its pistol form. Weiss gripped Myrtenaster as the dust rapier's dust chambers rotated, settling on the red, explosive ones. Ruby unfolded Crescent Rose into its rifle form, loading a round into the chamber of the sniper-scythe.

Their hearts pounding, the eight waited to see what happened.

"Holy crap, there's something's alive in there." Jaune whispered.

And it was. The sound of chains being snapped could be heard from within, followed by another snap. Then, they saw its cover budge slightly. Suddenly, whoever or whatever was inside began to slam on the cover.

The teenagers backed up, not taking their eyes off of the sarcophagus as the sound got louder.

The cover was knocked slightly ajar. Something green was inside. Then, its green, armored hand reached out and slid the cover to its right. It fell with a loud thud.

They broke out into a cold sweat. Each of them—even Jaune despite his cluelessness—knew the risks when they attended Beacon Academy. Being a hunter is a dangerous lifestyle, and they would face all sorts of problems.

A demonic sarcophagus containing something never-before seen on Remnant was not what they had in mind.

Suddenly, its green inhabitant rolled out of the sarcophagus. The armored being dropped to the teens' right, before planting a foot down, crouched down, and aimed something tiny at them. It was a pistol, but from how the weapon shifted a bit when he aimed, it had glowing blue parts in it, so perhaps it was dust powered.

The teens noticed that the armor was scarred and worn, a peculiar mark on the top left of it's helmet. It was the same red emblem on the cover.

Ruby couldn't help but think about how cool it looked.

Both he and the young hunters kept their distance as they pointed their weapons at each other.

The marine stood his ground, as did the people in front of him. From the looks of it, their weapons were something he had never seen before, except for the idiot with a sword and shield. Seriously, he had an appreciation for the classic, but not carrying a gun was just stupid.

His vision was blurry; it had been so long since he had seen actual sunlight that his eyes had a hard time readjusting. A few seconds later, he could see a bit clearer. A woman wearing a corset, looking somewhat like a gladiator, aiming a rifle, a man in green robes wielding dual machine pistols, a woman wielding, also wearing a white corset, and a...skirt, equipped with a grenade launcher, the blond with the sword and shield, a red hooded sniper, a white dressed rapier wielder, who reminded him of snobby and wealthy aristocrats, a black clad pistol user, and a woman dressed like a teenage bar-hopper equipped with yellow gauntlets.

Something about them felt off. He squinted his eyes and noticed—

"Hello? Can you understand what I'm saying?"

The one with the red hood asked him a question. The marine then realized how young she looked… how young they all looked.

'These are...kids?'

Annihilating demons for what felt like centuries may have dulled him to certain things, but somewhere deep within him, he still remembered the innocence of the far past. The innocence of youth.

'No.' he thought to himself. 'No children shall be harmed.' It was one of the oaths he had taken alongside his brothers in arms in the distant past. He may have failed his home then, but now…

This moment of calmness cleared his mind. He knew what to do.

The marine slacked his shoulders as he slowly pointed his pistol to the ground. He then stood straight as the young ones holstered their weapons away.

He knows that they were uncomfortable. From the outside, the visor obscured his face so to them, he was practically faceless.

The marine set his gaze at the youngest of the eight. The hooded girl had a glint of fear in her silver eyes, but he could sense something different about her.

"Um… do you speak Valean?"

"Ruby, what are you doing?" the blond boy whispered. Fighting the forces of hell had sharpened his senses, so his attempt to hide his intention was for naught. And what was this Valean? The name of the country he's in?

"Jaune," she replied, "Whoever this person is, he or she is probably confused at where they're at right now."

"They just busted out of that sarcophagus. For all we know, this guy—or gal—is a zombie or something."

"I don't smell anything rotten."

"Bet that armor masks the smell."

As they continue their whispered banter, he felt something he hadn't felt in ages; amusement.

'Perhaps… this means something.' The marine thought. Fighting was all he knew, yet these children had reminded him of something he had long forgotten. His feelings.

However, the other six weren't as amused. The blond girl looked back-and-forth between the hooded girl and him with a wary look. The gladiator girl in may have put away her firearm, but she was ready to draw them within an instant. The girl with the grenade launch—wait, it changed into a hammer. How did it do that? The marine always wanted something that could create explosions when he hit something, and that nearly made him squee in delight.

The girl with the hammer felt his gaze, and looked at him curiously. She noticed that when she moved her weapon, his gaze seemed to follow it.

"Ooooh, do you like my weapon?"

It was a simple question. The armored one gave a simple answer; a few nods.

With a grin, the girl stepped forward, "My name is Nora Valkyrie, and this here is my Magnhild!" she shouted, "There are many weapons in this world, but this one is mine!"

Nora twirled her hammer as if it was a baton. In a blink of an eye, she shifted it from its hammer form to its grenade launcher form. And switched it back again.

It was one of the most beautiful things the marine had ever seen.

"If you're wondering, the answer is yes; it can make things go boom even in hammer form."

To the surprise to the teens, he gasped. Sort of, the helmet obscured his voice as well. But they could tell how impressed he was.

"Oh, you think that's impressive?" The blond girl asked rhetorically, "Check out Ember Celica here!"

She raised her gauntlets, and he noticed something; there were shotgun shells inside them!

Noticing that he was fawning over her weapon too, she introduced herself, "Name's Yang Xiao-Long, and as you can see," she moved her forearms so he could get a better look, "When I punch things, anything will go boom, too."

His heart nearly stopped as he felt the sheer beauty of it. But he quickly controlled himself.

Speaking of quick, the girl in white began to yell, "What are you two doing?! Don't you remember that we're in the middle of our initiation and are currently being chased by two giant Grimm?!"

Fan-fucking-tastic. She was probably the life of the fucking party, wasn't she?

"And you!" she pointed at the marine, "I am glad that you are smart enough to recognize that we're not your enemy, but that doesn't mean the same goes for you! Who are you and where did you come from?"

As she continued to blather on, he tuned out most of what she said. The marine wondered if he should pay attention to her, but when she said two Grimm, he searched the horizon behind them.

A few meters in front of him, was a giant black scorpion-like creature with a skull-white carapace and face mask, its tail stuck inside a miniature iceberg. How could an iceberg appear in a forest? And why wasn't it trying to break free?

A squawk drew his attention skywards. A giant crow-like bird, also with a skull-white face mask, was circling above them. However, it kept its distance.

He knew monsters when he saw them, and whatever world he woke up in seemed to have pest problems as well.

"Weiss, is he even listening to you?" the one in black asked.

Weiss—the girl in white—turned around to face her, before noticing that the marine wasn't even looking at her. "The nerve!" she exclaimed.

Before anybody could continue, he raised his left hand. Now he has their attention. Clearing his throat, he pointed a finger at the hooded girl.

It had been a long, long time since he had last spoken a word. Considering what he had been doing, it was natural that he needed to get used to using his mouth to communicate again.

"Full name." It was short and straight to the point.

The teenagers—now knowing that the armored being was no robot, but a man—widened their eyes. So he could talk. But judging from how hoarse his voice was, it appears that he hasn't talked since… whenever he was entombed.

"Um… I'm Ruby Rose." She said sheepishly. It seems that she had trouble communicating.

He then pointed his finger to the blond boy, Frantically, he introduced himself, "My name is Jaune, Jaune Arc. Short, sweet… ladies love it."

"Again, do they really?" Ruby asked with a raised eyebrow.

Whatever answers Jaune had, the marine moved on to the girl in black. "Blake Belladonna." She answered; he noticed her bow was twitching. Whether it was wind or something else, he didn't care.

He looked at the blond girl. "Yang Xiao Long. Life of the party. Pleased to Meetcha" The girl grinned, a wide smile forming.

The marine finally settled his gaze on the girl in white in front of him. Or to be more precise, below him due to how he towered over them all. Her face was filled with contempt. After a few seconds of staring, she sighed and introduced herself. "My name is Weiss Schnee."

He replied with a nod. Next, he looked at the girl with the hammer. "Nora… Val... kyrie?"

The girl smiled and saluted, "Yessirree!"

Responding with an amused grunt, he pointed at the boy in green. "Lie Ren." From the way he said it, apparently he too was a man of few words. At least the boy was able to talk normally.

Finally, he set his finger on the redhead. "I am Pyrrha Nikos." She introduced with a bow.

A fucking bow. Who does that these days?

He shrugged internally, responded to the girl with a nod. Despite how archaic she looked and acted, at least she seemed polite.

Then, he cleared his throat again, asking one more thing, "Not soldiers. Why carry weapons?"

The teenagers looked at each other with confusion, and then Weiss answered, "No, we're not. We carry weapons because we are training to become hunters."

Cocking his head to the side, Weiss took it as a sign that he didn't have the foggiest idea. "You know, defenders of humanity?"

He continued staring.

She pointed at the Deathstalker and Nevermore, "Slayers of the Grimm, the unending tide of death?"

The heiress noticed that neither beast made any attempt to approach; the avian Grimm hovered a good distance away from the group, and the scorpion-like Grimm did not move at all—not even trying to extricate itself from the iceberg she incased it with.

She decided to worry about that later as she continued, "How can you not know what HUNTERS are? Anyway, point is, they defend humanity from the Grimm, creatures that have existed for centuries, forever the enemy of mankind. They—that is to say, we—are the last bastion of humanity, the role model all must look up to. We work under the four kingdoms." She sounded like she was quoting a book.

The marine nodded. So this world had kingdoms. He needed to read more about this world—no matter how boring he thought it would be—if he planned to survive in it.

"Soooo do you have a name?"

On hearing Ruby ask this, the marine stiffened.

'My name… what was it?'

It didn't help that he still had trouble speaking. He was willing to flat out tell her- he no longer remembered his own name.

Unfortunately, he never got a chance to answer, because he heard a howl coming from behind him.

"Guys… what are those things?" Jaune asked, his voice shaking in fear and confusion.

"A Beowulf pack," Blake answered, readying her weapon, "And—what are those?"

He turned around as the young ones readied their weapons. What he saw made his blood boil.

It wasn't the werewolf-like creatures, but the ones behind them. He counted their. 'Fifteen runts… a platoon. Big ones… three.'

The Beowolf pack—as Blake called them—was snarling at the group. But they gave way to the smaller brown creatures and the three larger gray things.

"Are these new kinds of Grimm?" Pyrrha questioned, "I don't think I've seen them from the books."

"Demons."

The teenagers looked at the marine, whose left fist was clenched.

"Wait, hold on." Yang said, "Are you serious—"

He turned to his right. She could feel the anger from his eyes. "Whoa, okay. I guess you are."

Jaune did his best to not panic. Fighting Grimm was one thing, but nobody ever said that he'd have to slay demons. 'Keep it together, Jaune… this isn't like those games where you hunt demons and save the princesses.' He thought to himself, 'The movies keep showing that to get rid of them, we need prayers and stuff. But I skimped out on exorcism class…'

"Guys, I doubt we can pray them away." The blond told the others, "What do we do?"

"Kill them all." The man in green cracked his knuckles as he answered Jaune. Turning around, he ordered to teenagers, "You run. Find safe place."

Yang intervened, "Whoa, hold on there. You're going to take them all on by yourself?", and that question was replied with a nod, "Well, I don't know how serious you are, but no huntsman fights alone."

"No." he retorted, "Too dangerous. Kill them myself."

He wanted to warn them that whatever these Grimm were, they were nothing compared to the demons. He wanted to assure them that he had been fighting the fiends of Hell for years, so they didn't need to worry. He wanted to tell them to run away so he could protect them better.

The frustration of his incapability to properly communicate angered him even more.

"The Doom Slayer is loose! Kill him! We must kill him!"

One of the demons had talked. In all the years the Doom Slayer had fought them, such an event had never occurred.

'They had never talked before.' He thought, 'Why now?'

The teenagers began to feel fear for the first time as the demons began to chant, every one of them for the marine's death, and the large gray trio roared alongside the Beowulf pack. The smaller demons clenched one of their hands, a ball of energy gathered into their palms. Then, they flung balls at them. Balls of fire.

"Take cover!" Ruby shouted, pointing at the altar. The teenagers ran towards it as the volley of projectiles landed where they once stood, each hiding behind the pillars.

"Okay, this is officially the worst initiation ever!" Jaune cried out, "Let's get out of here!"

"We'd love to, Jaune," said Blake, "but the fact that there are two giant Grimm, a pack of Beowolfs, and those… demons on our backs, I don't think running away is an option!"

"Wait a minute!" Ruby cried, "Where did that new guy go?"

She got her answer when she heard screams of pain coming from the direction of the Beowulf pack. Blood and limbs were flying.

"Whoa."

(Play Doom BGM: At Doom's Gate; any version you want—preferably the 2016 one)

The marine… no, the Doom Slayer, charged forth into battle.

He shot one of the beowolves with a charged shot from his pistol. The beast was stunned, the Slayer saw that it glowed blue for a bit, his HUD indicating it was ready to be put out of its misery. As he approached the creature, the blue glow turned orange.

Time for a Glory Kill.

He grabbed its lower jaw, and with ease, the Slayer tore it off. He proceeded to embed said jaw into it's eye socket.

Blue energy flew out of the thing as it fell apart. The health bar on his HUD indicated that he now had 50 life points.

"Works on them too, eh?" he joked. With a grin, he aimed at an imp and blew its skull out. Both Beowolves and imps charged right at the Slayer. Fortunately, his supernatural agility made it easier for the Slayer to dodge their melee attacks and the imps' fireballs.

He grabbed one of the imps and threw it right into the group of beowolves. One of the Grimm managed to get close and clawed at him, but the Slayer answered by tearing its arm off.

Hearing an imp's growl, he turned around—a left fist extended—and slammed his fist into its skull. Seeing its glow, he shoved his harm, tearing out the creature's 'heart'. He squeezed it until it popped, like a disgusting balloon, and pulled his arm out of the demon as it fell to the ground.

Wiping the gore off of his gauntlet, he continued his onslaught as the number of imps dwindled.

Meanwhile...

"Oh, man… I think I'm gonna be sick."

"Cool it, Vomit Boy. Now's not the time; I'm trying to enjoy this!"

Pyrrha observed the man carefully. They had called him the Doom Slayer. The sarcophagus behind them had scratches that weren't just runic letters; no doubt it was created by whatever trapped the marine. Perhaps the demons?

What she could tell from his actions were that he was a ferocious warrior. The champion saw hints of cunning in his attacks; dodging the demon's bites and swipes with ease. And his speed! She had her share of opponents, but never had they display such swiftness the Doom Slayer had.

'He's dangerous. Good thing he's on our side...'

One by one, the beowolves and the smaller demons fell. The Doom Slayer had created a pile of gore and torn apart limbs. Standing on the corpses of his foes he blew them apart. One Beowulf managed to grab his left arm, only to be pulled up and have pure energy melt through its torso.

Then, one of the beowolves turned around, and saw the would-be hunters watching from the altar.

It howled, calling attention to the new preys.

"Seems we need to do our job." Weiss stated.

"Stand your ground!" Ruby ordered, "We can't leave him behind!"

Yang retorted, "Didn't you say there's no point in fighting these things? Not saying that I'm not eager for another fight, but…"

"That was before we stumbled onto that… that guy!" Ruby countered, a finger pointing at the Doom Slayer.

The older sister of Ruby put her fingers on her chin, before snapping them, "You know what, let's just call him Doomguy!"

Blake rolled her eyes, "That sounds ridiculous, but I can't help but think it fits, since those… demons called him the Doom Slayer."

"Anyway," Ruby continued, pulling out Crescent Rose from her back and shifting it into its scythe form, "We have to hold the line. I don't want to leave, er, Doomguy here all alone. That wasn't what hunters would do!

They draw their weapons as the pack come closer. The Doom Slayer had cut down most of them; the teens could handle them.

It was at that moment when Ruby saw the Slayer being thrown away by one of the large demons. She wanted to help him, but she was needed more by her team.

'The Hell Knight and Imps… why are they here?'

Did whatever powers that brought him into this world make a way for them to follow? Would there be more demons invading? Would Vale and the other three kingdoms be consumed by the Forces of Hell, just like last time?

'Fuck that.'

Doom Slayer stumbled for a bit as he got to his feet. The Hell Knights were tough sons of bitches, and even though his pistol had inflicted damage, it was superficial. He needed a weapon—a proper weapon—in order to deal with these three. But all he saw were corpses and red grass.

He needed a better gun. A big gun… a big fucking gun.

Slayer, Slayer… it's been a long time.

Doom Slayer looked around for the source of the voice. Checking his helmet radio, he noticed that it was turned off. Turning it on, all he heard was static. Still, the voice sounded familiar… he had few friends before Hell invaded his home, and none whatsoever since.

We shall meet again in due time… but right now I believe you need a pick-me-up.

He heard a noise coming from his right. The familiar red color of Hell's energy was transporting something near the mountain of Beowulf and Imp corpses (the former slowly fading away). A Hell Knight was about to pounce. He rolled and took a few potshots as he made his way to the hellish energy. The other two followed, but he outran them.

As the energy peaked, he averted his eyes from the brightness… and saw a familiar weapon.

A combat shotgun, surrounded by frag grenades. Both mods for the firearm were there, and a pair of metal boots with thrusters on the calves was there too. 'The freaking Delta V jump boots?' There was even a 'Mega Health' as he had taken to call the flesh regenerating spheres and forms 200 points of armor.

I thought making you get all those upgrades and mods of yours again would be a waste of time. So I did you a favor and got them all right here. Don't worry, you'll find your other toys when the time comes. For now, just take these and you're all set, Slayer.

The Doom Slayer wondered what he was talking about. 'He said 'Again'… I must have gotten out of that sarcophagus sometime ago, but when?'

He shook his head, 'No. No time for that. Three demons to kill.' He thought as he looked at the teenagers blowing apart the Grimm. 'Then I help them.'

They were holding their own. Pyrrah Nikos and that Jaune boy were fighting side by side, though the boy didn't seem to be doing much. Pyrrah was as a goddess of battle, though nothing compared to the marine. Ruby was utilizing hit and run tactics to back up her sister, who was tearing through Grimm like a battle tank. Blake and Weiss were keeping the Grimm away, wearing them down with attrition.

It wasn't enough.

In an instant he picked up his supplies, surprised by how the shotgun had 60 shells.

You've upgraded your suit with the Argent Energy to make you stronger, remember? That includes more bullets. Don't worry; they won't blow up in your face unless you do it yourself. As I said, you will find them in due time—maybe after you get out of here with those young mortals and follow them to wherever they're going.

A part of his mind wondered what other 'gifts' he would get later on. As if hearing his thought, the voice replied.

You will get them, Slayer. Think of it like one of those video games the mortals created. You want better stuff? Progress further into the story to get them. Explore every nook and cranny of a level if you have to. Fortunately for you, you have progressed a bloody lot in your last adventure… I'm just saving your progress by giving back your achievements. Well, some of them, anyway. Wouldn't be fun if you got everything from the beginning, wouldn't it?

The Slayer couldn't help but agree. He always loved a challenge.

Cocking a shell into the chamber, he turned around and fired away. The pellets tore into belly of a Hell Knight, another blast ripping into its leg, and pulled the trigger. Now on its knees, he charged the demon and punched its jaw with his right fist.

It was blown apart. Before it could get the chance to comprehend its injury, the Doom Slayer had jammed the fingers of his left hand into the base of its neck. Using all his might, he yanked hard to his right. The Hell Knight's head was torn off its body.

In quick succession, the Slayer inserted the Charged Burst mod onto the shotgun. He aimed at the second Hell Knight as the three lights from the mod blinked one by one. Even as the beast got closer the topmost light lit, he let loose a burst shot, almost blowing through it's chest. He finished it by splattering its brains with another shell.

The final hell knight slammed into the distracted Doomguy, who recovered midair, replacing the front half of his shotgun with the Explosive Shot mod. He fired three normal shots at the demon, breaking its arms and rupturing its torso. Roaring in pain, the Knight 'screamed', but tried to leap at him once again.

It would be its last mistake. Gripping the shotgun's pump loader, he waited for the demon to be airborne as he pressed his thumb on a button in front of the loader.

The Hell Knight leapt skywards, a clawed hand prepared to attack. The Doom Slayer retaliated by firing the Explosive Shot. The enlarged projectile flew in an arc, heading straight into the Knight.

As the shot connected, the projectile combusted. The explosion created a hole where its chest used to be. The Hell Knight fell flat on its face, its momentum stopped as gravity did its job.

(End BGM)

The Slayer took a few calming breaths. It was done; he had his fun.

'Wait.' He began, 'The voice said something about my last adventure… when—'

He remembered things...The U.A.C., an AI. Crucible... Argent energy…

"I am not the villain in this story. I do what I do because there is no choice."

REROUTING OF TETHER COORDINATES COMPLETE

"Our time is up. I can't kill you, but I won't have you standing in our way. Until we see each other again…"

'Samuel Hayden… Not the villain my fucking ass, you're the villain in my story. One way or another I am going to find that robotic fuckhead and shove the Crucible up his metallic ass!'

Calm yourself, Slayer.

'He betrayed me!'

Indeed he did… but there's no point getting furious over it. I may not have much power beyond providing you with your toys, but I know for sure that you will face that man again.

'How would you know… I was tethered away, but was inside the coffin. Are you responsible for sending me here?!'

No, I'm not. Do remember that I betrayed my kind to join your side. Why would I betray you, knowing what you are capable of, Slayer? I am no fool. Plus, I just found you a few moments ago.

Then, something clicked within the Doom Slayer's mind. A memory from his time in Hell. Centuries of battle, immeasurable amount of demon corpses he had created. Out of all the chaos, there was only one good thing that happened.

A lone demon, doing something extremely intelligent; he did not fuck with him, and joined his side. He read a codex entry mentioning a Betrayer amongst the demons. The voice belonged to him.

I also made that Praetor Suit of yours. So in a way, you owe me. Do not be angered; it will be beneficial to your cause against the slaves of Doom.

The Slayer remembered something else, 'Wait. You talk. The demons here did too. Why?'

Oh, we could always talk. Most of us just don't bother to do so when we're killing. You must've read those Slayer Testaments the others had planted in Hell. And don't you remember me begging for my life as I tried to join your side?

He paused, and then replied by shaking his head.

Eh, I guess it's for the best; that was pretty embarrassing. Anyway, you must be wondering how I'd find you in this world, and how I can talk with you like this, and whether we'll meet or not… but I believe you have people waiting for you right now.

Blinking, he realized that he has forgotten about the eight youths he just met. When he turned, he sighed in relief, as that they were a few meters away from him. For some reason, despite leaving behind a mountain of dead beowolves, they had nary a scratch on them. 'Either they're weaker than I thought, or the people of this world are stronger than I think.

The hooded girl, Ruby, slouched her head with her mouth agape. The Slayer walked to them when the girl squealed in excitement.

"THAT WAS AWESOME~!" she cried out, "How did that shotgun work? How could you change its form so quickly? How how how?!"

The Doom Slayer was overtaken by how excitable she was. But deep inside, he was overjoyed; another lover of weapons!

"Alright, alright, tone it down a bit, little sister." Yang said, putting her hands on Ruby's shoulders.

'Sister? Looked different… half-siblings?' The Slayer wondered.

Ruby apologized, which he accepted with a wave of his hand. Yang approached the Slayer, "Sorry about that, my little sister can be quite the fangirl when it comes to weapons." she said, as she herself eyed his, "Gotta say, it does look impressive, but not as cool as mine." She grinned at him while brandishing her shot gauntlets; the Doom Slayer could sense her joking tone.

He responded by putting his hands on his hips, looking at the girl in faux disgust.

Yang laughed at his posture, "Oh, I'm just kidding, Doomguy. No need to pout."

That made him flinch. "Doomguy?"

Ruby elbowed her sister, "Yang! Sorry, but… since you haven't told us your name, she came up with that nickname. At least it sounds nicer than Doom Slayer?" she reasoned with a sheepish shrug.

For a moment, the Slayer looked away. He knew that he should've told them his name.

'But… I can't remember.'

Come now, Slayer. I never realized you could experience an existential crisis. I may not know it, but whatever your true name is; you better make sure you told it to the right people. You know how some demons are powerful enough to control you using your true name…

The armored man contemplated the Betrayer's words. He wouldn't be surprised if one of the Great Lords of Hell had taught their followers the power to manipulate mortals and weak-minded people.

He was neither of those things.

'Still… a better name than none.'

The Doom Slayer looked down, Yang and Ruby looking at him,worried. The older sister scratched her head, "Hey, look. I'm sorry if you don't like the name. We could—"

"No."

Again, one word was enough to get their attention.

"It's fine." The Slayer continued, "I like it."

The blond brawler pumped her fist and grinned, "Hah! I told you he'd like it! Welcome to Remnant, Doomguy!"

The Doom Slayer… no, Doomguy felt something from his heart. A sense that he hadn't felt since the hell meat party began.

Relief.

Huh. They say that changing your name will also change something within you. Guess it's sort of true, huh?

Doomguy internally nodded at the Betrayer's commentary.

Blake chimed in, "By the way… do those demons have names?"

Looking at the girl in black, he titled his head, so she elaborated, "I mean every Grimm has their names. Surely those things have one too… unless you don't know and named them yourself?"

He looked aside, remembering the names of the demons. 'No harm in telling.' He figured. So he did, "Small ones… Imps. Big ones… Hell Knights."

Blake stroked her chin, "I see… appropriate, I suppose. The smaller ones do remind me of imps. The large brutes, too. Nothing knightly about them, but the names matches their size."

Yang's grin promptly returned. "Know all about sizes, dontcha?" To the glares—and in Ruby's case, confused look—she received, she only provided a grin as a reply.

"Well, speaking of names," Ruby interrupted, "can you tell us yours?"

Doomguy lowered his head for a moment, before raising it with an answer, "Don't remember."

Short, simple, and honest.

"Oh, er... Okay...I'm sorry... Sorry to hear that!" the young girl said, her face showing her guilt at bringing it up.

Then, he did something nobody expected, not even he himself knowing why he did it.

For a moment, the universe paused. And then—

Doomguy raised his right hand, and petted Ruby Rose's head.

Within his helmet, his eyes widened, 'What am I doing?' he wondered, but as his hand gently petted the girl, Ruby didn't seem to object. In fact, the action cheered her up, indicated by the adorable smile she gave him.

HNNNNNNGH.

It was at that point Doomguy experienced something so rarely seen in hardened warriors, trained in demon slaughter via tearing apart flesh.

Poets call it compassion. We plebians call it a "D.A.W. overload."

By the Nine Circles... and here I thought your only emotions were anger, rage and satisfaction. It seems that you like this little mortal.

Removing his hand, Doomguy sighed. Not because he didn't enjoy it, but because of what the Betrayer said; he was calm—a state he had not been in for a long time.

Come on, now. I don't plan to do anything to her, honest. I may be a demon, but believe it or not, some of us have standards. Messing with juvenile mortals doesn't interest me at all, and I only deal with weapons and armor. Speaking of which, I'm glad that the suit's function for putting multiple weapons into the hammer realm still works. I wonder if any of them realize it…

Just as the Betrayer hoped, Weiss Schnee took notice of the glaring flaw in the Doomguy's outfit. Something was missing, and it was-

"Hey, hold on… where have you hidden your pistol? And didn't I hear shotgun blasts? I don't see them with you. And what's with those boots?"

Oooh, this is going to be funny.

'For once, I agree.'

Doomguy answered by holding out his right hand… and then in a blink of an eye, his pistol was there.

"W-what?! When did it—"

Before Weiss could finish, he pulled his hand back. The pistol disappeared, and when he raised it again, the shotgun replaced it.

Nora was gaping in awe, or perhaps jealousy. Ren too, albeit his mouth wasn't as wide as hers. Jaune scratched his eyes in disbelief, and Pyrrha gasped, putting her hands close to her mouth.

Inside his helmet, Doomguy didn't realize that he was grinning. He continued his demonstration as the teens looked on in confusion. He detached the Explosive Shot mod of the shotgun, putting it behind him… none of them saw what happened but it was suddenly replaced by another muzzle with the Charge Burst mod attached.

"Oh. My. God." Ruby slowly said. "You can do magic tricks!"

"Don't be ridiculous!" Weiss interrupted, "It's obviously his semblance!"

Doomguy didn't know what a semblance was, but if that meant superpower or something, he'd take it. He flipped his shotgun skywards, but before any of them could see it fly, it was already gone. He was holding his pistol again.

"Alright, I'll admit it." Yang said, "That's cool."

"But it's impossible!" Weiss shouted, "I read that some semblances leave a trace, but what he did… there's none whatsoever! And those pouches on your waist couldn't possibly hold them in... How are you doing this?!"

He answered her with a shrug.

"What do you mean you don't know?!"

After a slight pause, Doomguy repeated his answer; another shrug.

This infuriated Weiss, who was pinching the area between her eyes.

As amusing as this is, Slayer… you got company.

Just then, a horrible roar filled the area.

"What was that?!" Jaune cried out.

"Over there!" Blake shouted.

The group turned to the direction she pointed at. Doomguy could feel the vibration of its footsteps. There were many giants within Hell's ranks, whether they were as big as tanks or of titanic proportions. He recognized those footsteps anywhere. He responded by switching to his shotgun.

Ruby then asked, "Um… is it as big as the Hell Knights?"

"Bigger. Meaner. Stronger."

Yang cocked her shot gauntlets, "In other words, bad news."

She had no idea.

A green explosion blasted the surrounding trees, incinerating the area. From the smoke walked a goliath of a demon. Normally, the usual depiction of the devil in many cultures involves a red skinned being with satyr legs and big horns.

The Baron of Hell matched the description.

The teenagers stepped back a bit as its glowing green eyes glared at them. Now that was an intimidating demon.

"What… what is that?" Ruby asked, fighting to stop her trembling hands.

"Baron of Hell." He answered.

Jaws chattering, it was Jaune's turn to ask Doomguy "S-s-so… is that the boss of the demons?"

"No. More than one Baron. I sense just one. Never met actual boss."

They were relieved, but they didn't relax just yet.

"It may be just one," Pyrrha added, "but I do not think it is wise to engage it."

"True. You all run."

Ruby was flabbergasted, "W-what?! What about you?"

"I hold him off."

"Alone?!"

"Fought many. Killed many. Will be fine."

Before he could charge, he saw something else emerge from the forest. Followed by three others that looked similar to it.

Imagine a bull/pig hybrid from Hell. Except these ones eat meat, aren't really mammals, have chitin plates on their front sides, a very big mouth… and are pink.

"Pinkies."

Yang raised an eyebrow, "Not a very scary name."

"No names. I call them that."

"What can they do?" Pyrrha asked.

"Know what warthogs are?" he answered with a question of his own.

(Pyrrha, what's a warthog?)

(Not know, Jaune)

Seeing how they nodded, Doomguy continued, "Much worse. Eats meat. Tough head with armor up front. Attack their backs."

Now the stakes were higher. Usually, he wouldn't hesitate on taking them all on by himself. He knew their weak spots, knew the proper strategies to outmaneuver them.

But this time, he wasn't alone. Fucking escort missions.

'Can't risk their safety. Have to get them far away.'

The Baron let out another roar. Then, something else answered it with a screech.

"You guys..." Jaune shouted, "Nevermore incoming!"

Looking up behind them, Doomguy saw the giant bird Grimm approaching fast. It stopped itself by flapping its wings forward… and sending its feathers forth like spears!

Doomguy swapped Charged Shot for the Explosive Shot mod, shoved the teens away, and used his jump boots to reach higher into the sky.

Time slowed as he aimed his weapon in the direction of the feathers. He pulled the trigger, and the explosive round made its way to them. A few seconds later, it hit one of the feathers and exploded, the force threw off most of them.

But not all. He saw more incoming.

'Shit.'

He turned his head, the others were already getting out of the way, but one was falling behind.

"Jaune!" Pyrrha shouted.

Turning back to the feathers, Doomguy saw that they would hit Jaune if he got out the way… so he braced. Using his boots for a second jump, they did their job. He was in their way.

One. Two. Three. Four… Four feathers struck him. Thankfully, his armor piece was still intact when he was hit, stopping the majority of it.

Ruby saw what happened, and cried out his name, "Doomguy!"

The Slayer landed, recovering flawlessly.

'Armor and health at one-fifty. A strong one.' He muttered internally.

Turning his head to where Ruby was, she suddenly disappeared, leaving rose petals. Seconds later, she was right in front of him.

It took everything within him to not accidentally blow out her chest. He was never fond of teleporting demons like those Summoners (or was it Archviles?), and those who were stupid enough to appear right in front of him usually ate lead.

"Are you okay?" she asked, "Wait, stupid question. Come on, we have to get out of here, and you're coming with us!"

Ruby tried to convince him, pulling his armored arm. Despite his weight, the girl desperately struggled to get him—him of all people—to safety alongside her friends and half-sister.

'Oh. How nice. Somebody cares. That's...new.'

The way I see it Slayer, as much as it pains me to say it… this isn't the right time to Rip and Tear.

Doomguy would have loved to enjoy himself, but this little girl… she was persistent. "Please! I know you're strong, but we can't do anything in here. Not with that Nevermore flying around!"

'Huh. True, never fought a real flyer before.'

Now that she mentioned it, I've never seen any demons that could properly fly. The Lost Souls just go about, never too high, and the Cacodemons were just oversized balloons that spat. And I've never seen you take on any flying demons before.

'And none of my current weapons can reach its height… give me the rocket launcher.'

Oh… were it so easy, Slayer.

'What?'

I did say I would help you… but there's a price for everything. See, it takes a lot out of me to transport your toys into this world, and I need to recharge myself for the day. Surely you understand.

He clenched his free hand in frustration.

Now, now. I can transport a bit more. Say, a Great Communicator?

Doomguy widened his eyes. 'Where?'

I believe she could lead you to them.

Looking down, Ruby was panting. "Man… you're so heavy!"

Behind her, Yang was running to them, "Come on, what we are waiting for?!"

"Doomguy… he's not budging!"

Yang clicked her teeth, "Look, big guy. I know you probably want to rip and tear these things all you want, but we don't have time for that! So either you move or so help me—"

"Okay."

The blond stuttered, "W-what?"

"Changed my mind. Let's go." Doomguy then looked to Ruby, "Know where to go?"

"Um, yes! Can we please move?"

"Lead the way."

Personally, he would rather go and find the cliffs on his own. But the fact that he was in an unknown world and fate had given him the job of protecting the eight teenagers meant wandering off as usual wasn't the best idea.

The Doom Slayer, running away? The lads back home would never believe this! Then again they'd probably rip my testicles off and stuff them into my skull, but still!

'Shut up. Merely tactical retreat.'

Hehehe… Whatever you say, Slayer.

As Doomguy, Ruby, and the others ran towards the Deathstalker, passing by it, Doomguy noticed that the Grimm was about to break the ice. He decided to be nice for once by shooting an Explosive Shot at it.

Behind them, the Baron of Hell roared. The Pinkies charged with incredible speed towards the group, the Baron followed and threw a couple of green fireballs at them. They missed, but the splash nearly slowed them enough to be caught.

Well, staggered one. This time, Jaune kept his footing as they entered the forest, but Blake tripped. Fortunately, Doomguy was right behind her, pulling the back of her shirt, preventing her fall.

"Thanks!" she shouted, catching up with the others. Doomguy looked behind as he kept moving, 'Pinkies charge fast. Trees might slow them down. Baron could just burn them.'

He turned to the teens, his supernatural speed helped him catch up, but Doomguy kept his distance to cover their six.

The Forces of Hell have entered Remnant. But the legendary Doom Slayer is there to protect its denizens. He shall wreak havoc upon the Slaves of Doom, and he will Rip and Tear them apart until he feels like stopping.

And he never feels like stopping.

Holy shit you guys.

Almost 10,000 words, including my author's note, but will probably get to it or more when I edit this… DAMN.

I'm still working on my other fanfics. Don't worry, you'll get them… sooner or later. Depends on what happened in my life—if I'm not inspired enough, then it will be slow. But rest assured that I still have plans for them.

But as for this, until I bought the game, collect all the bits for the codex, find the weapon mods and see how the upgrades for the suit and guns worked, and the collectibles that allows me to view the models for everything for the details, chapter 2 may take a while.

Don't bitch about spoilers; I've already warned you right at the beginning.

I originally planned to cover the entire E8V1 of RWBY, but my gut tells me that this is the right time to finish the chapter. Besides, as much as I enjoy writing long ass chapters, even I get tired.

If you know your Doom, and played the new game, you know in what order Doomguy will get his weapons. I think you can guess which two I'm referring to. Enjoy!

Oh, and the Betrayer is in the game if you read the lore. As what kind of demon he is... what's the one demon that never appeared in the campaign, but only in another mode of the new game?

His voice is inspired by the Merchant from Resident Evil 4. His behavior too, in a way.

Anyway, Read, Review, and Rejoice!

So, here it is! The revised version by boothnat. You can probably guess which words were fixed by boothnat.

Still, as I said before they didn't play the new DOOM. So I fix some stuff to match canon. Also some words needed to be changed because I have my own interpretations of how Doomguy acts.

Hope you don't mind, man.

There are also some fixes and additions from me; can't believe I didn't see the Pinkies as warthogs. Couldn't help but do an obligatory RvB reference.

Anyway, it would take a while until I finish Chapter 3. There's a life I need to fix, and mine is a goddamn mess.

Hope the poll helps in deciding where do I take the story...
