Doom DXD

"Until we see each other again"

And with that, Hayden sent the Doom Slayer into the unknown.

The Marine seethed, unable to do anything. Transported against his will, he would have to wait until arriving at a new location.

An alert on his HUD informed the Marine of an incoming signal. The sender is shown as 'Unknown' with only static coming through. After a few seconds, the Slayer heard something.

"…I…ca-AT-….cali-cali-calibratinginginging…..trrrrrkkkkkkkkkssssssssccchhh-bing…Calibration Complete. Greetings Doom Slayer, I am VEGA."

VEGA. Though he took a backup of VEGA's source code, that doesn't explain how it is contacting him right now.

"To answer your question, yes, I am that VEGA. I thank you for taking a backup of myself. It has taken the length of time from when you made the backup to just now for me to correctly integrate myself with your suit." A few more beeps and a representation of VEGA appeared in the visor. A hollow blue circle cut into three, with another circle in the middle. "99% of my capabilities had to be disabled in order for me to come online. Though I am greatly hindered, I will still be able to assist you in your future endeavors." Some more beeps and another screen opened up. "We are currently trapped in an area referred to as the dimensional gap. From what I have been able to gather, Dr. Hayden did not actually set a physical destination for you. In fact, I believe that this is the exact place he meant to send you, in hopes of trapping you here forever." The extra screen disappeared. "Since I have integrated with your Praetor Suit, I can activate the Tether system to travel to the nearest dimension. Do you wish for me to do so?"

The Marine nodded. VEGA continued speaking. "Be warned though, I cannot guarantee we will be landing anywhere familiar. We may land in Hell, Earth, Mars, an alternate Earth or a completely Alien planet. It may take many jumps and many attempts before we can even get close to our original dimension, and there is no guarantee we will succeed during your lifetime or any lifetime. Do you still wish to proceed?"

Without any hesitation the Doom Slayer nodded again. What other choice was there?

"Very well. Scanning nearby dimensions." Trrk-tik. "Dimension found. Activating tether system. Jump in 3, 2, 1, Jumping now."

Just before the familiar light enveloped his body, the Doom Slayer sees a Great Red Dragon coming towards him. Just as the Dragon opened its mouth to eat the Doom Slayer, the tether system activated, transporting the marine away just in time.

As the light vanished, the Scourge of Hell landed heavily on his feet, the impact compensation message appearing. Standing up, the marine looked around at his location.

….which is apparently the grounds of a Japanese school. However, the completely white sky tells him that this is most definitely not earth.

Trrrrrk-tik. VEGA spoke again. "Tether activation successful. Location is currently unknown. Good news Doom Slayer, all of your weapons and upgrades have survived the trip intact."

The Marine swapped out a few weapons to ensure this fact, and settled on the old standby of the Combat Shotgun with Explosive Shot modification.

Trk-tik. "I am detecting life energy in two groups roughly 150 meters ahead of you. Creating a mini-map and waypoint for you now." A mini-map appeared on the top left of his vision, and a waypoint marker showed the location of the two groups. The Marine moved off at a steady jog, wondering what he'll find this time. Whatever it is, he'll be ready.

Rias has just finished briefing the members of her peerage on the battle plan when the announcer spoke once more. "Attention, attention. An unidentified intruder has appeared in the battle grounds. Until further notice, the Rating Game is suspended. All Devils are to congregate at the courtyard for further instructions. Any attacks on opposing Devils will be not be tolerated." The message looped one more time before ending.

Rias looked over at everyone, but they are just as confused as her. Since faking an announcement would result in an automatic disqualification, she knew Riser would not do something so underhanded, especially with how sure he was of his impending victory. So Rias gathered her pieces around her and calmly made her way to the courtyard.

It took a few minutes to get there, but by that time Riser and his entire Peerage was waiting for her. As usual, he had a haughty look on his face. Rias stopped when they were roughly 10 meters apart.

"Don't you feel lucky" said Riser, "that the Rating Game has been postponed? After all, since my victory was assured, you must have sneaked someone into the arena to cause this ruckus."

Issei growled at that. "Like our King needs to resort to underhanded tricks to beat your face in!"

Riser simply ignored him. "There's no point in delaying the inevitable. I WILL have you as my wife Rias."

Rias could feel the bile rising in her throat, and is unable to reply to him without throwing up. When she got her bodily functions under control, the sound of footsteps reached her ears. The heavy thumps did not sound familiar to her.

Turning to her right, she looked just in time to see a man in green and black armor walk out of the trees, pushing a branch out of the way while holding what looks to be a gun of some sort, though one she has never seen before. The armored being took two steps out of the trees before stopping to look at them, weapon at the ready.

Rias could feel something off with the intruder. He didn't feel human, but he didn't feel like an angel or devil either. Actually, now that she's paying more attention, he feels like a mixture of human and devil energy. It actually feels like he is absorbing devil energy somehow. It is a strange situation, which Riser completely ignored.

"Hey you!" Riser demanded, "Who are you and how did you get here?!"

The armored being didn't respond, and instead tilted his head slightly.

Trrk-tik. "Language identified Doom Slayer. Auto-translating to English now."

When he stepped out of the woods, two groups of kids iss not what he expected. Even stranger, one group is dressed like they're about to go to school, while the other group is dressed like … some horny guy's harem fetish.

The only male on amongst the group of females spoke again. "I said who are you? I demand you answer me!"

The marine ignored his shouting, pegging him as a spoiled brat, and instead turned his attention to the other group. Looking more closely, he realized that they must all be high school kids or younger. Two of the girls look like they should be in middle school. But of course, the spoiled brat decided to throw a temper tantrum.

"Since you refuse to identify yourself, I will force you to comply by force! Mira, bring him to heel!"

The red headed girl in the opposing group said something he didn't catch, while a blue haired girl came at him with a … wooden staff? She ran at a speed well below what he could move at, and jumped in the air yelling "This will teach you to disrespect Lord Riser!" and brought the staff down on his armored head.

Just as the Marine expected, the wood broke as it made contact. A glance at his status bars showed that no damage had been taken. The girl looked at her staff as if the impossible had happened. What other outcome could have occurred? It's a wooden staff against one of the most advanced armor system in the known dimensions, of course the staff would break.

"That-that, how did, that-that-that's impossible!" she shrieked. The Marine simply put a hand on her shoulder and gently pushed her aside.

Trrk-tik. Trrrrrrk-tik, trrk-tik-tik-tik. "Energy Analysis complete. Doom Slayer, the female exudes an energy similar to hell energy. Upon further analysis, every member of the group this female is part of exudes the same energy pattern. The sole male member has the highest amount of hell energy. Continuing analysis on other present parties."

A red outline highlighted the mostly female group members, including the one that had just attacked him. Are they all demons? They look like humans, but they look nothing like the possessed or unwilling. The group of school kids gained a yellow outline, marking them as neutral.

Trk-tik. "If you are wondering, yes, they are demons, or are related to demons, though not the ones you are used to fighting. As they have already shown themselves to be hostile to you, I recommend neutralizing the threats."

When VEGA said they are related to Demons, the Marine knew exactly what to do. The gentle grip turned into a fist of iron. Mira cried out in pain, but the Marine simply put the barrel of the shotgun on her chest and fired a single round.

Mira flew back, blood coming out of her mouth and chest. As she hit the ground, the female devil is engulfed in a bright light. The announcer came back on "Lord Riser, 1 pawn retired. Emergency medical personnel to the infirmary immediately!"

The Doom Slayer merely cocked the shotgun, loading another shell into the chamber.

Riser has an angry look on his face at the loss of his pawn. "HOW DARE YOU! Burent, Marion, Shuriya, teach this lesser being a lesson."

"YES LORD RISER!" they replied. Releasing their wings, they flew towards the Marine at their top speed.

The marine ran forward to meet their charge, swapping out the Combat Shotgun for the Super Shotgun. The two maids are in the front, while the…belly dancer brought up the rear.

The Doom Slayer ducked under the first maid and put one shell into her stomach. The second shell is fired point blank at the second maid's face. Reloading, the marine stopped and fired at the belly dancer, who is able to only partially dodge the shot.

Stunned, Shuriya did not see that she is going straight towards the marine, who merely held out his left arm and clotheslined her, before grabbing the devil and slamming her to the ground. In great pain, Shuriya is unable to do anything as the Marine lifted up his left foot, before bringing it down and crushing her head.

More lights enveloped the fallen devils, with the announcer coming on again. "Lord Riser, 3 pawns retired, critical condition. All Medical personnel are to report to the infirmary immediately!"

The Scourge of Hell simply reloaded.

"HOW DARE YOU!" screamed Riser. "I'LL HAVE YOUR HEAD FOR THIS! EVERYONE ATTACK!"

Riser, Mihae, Yubelluna and Ravel rose into the air on their wings to give them better line of sight for their long range attacks, while the others charged forward on the ground.

Xuelan reached the Doom Slayer first, striking out at him with her first. He responded by breaking her left arm and crushing her skull.

Next came Ile and Nel, both with their chainsaws out and running. Doomguy took out his own chainsaw, bringing it down on Ile. His chainsaw tore through hers, before he carved her body in half from shoulder to hip. Nel screamed in horror and charged forward as well, but the marine simply batted her chainsaw away before cutting her right down the center.

As the three disappeared in flashes of light, Ni and Li came forward in coordinated strikes. It was all for naught, as the Doom Slayer dodged each strike before sweeping out the legs from Ni. As Ni fell, he grabbed Li by the head and brought it down upon his knee, caving in her skull. He then curb stomped Ni, crushing her head underfoot.

Siris tried to take him one on one with her Zweihänder, but he merely caught the blade before ripping off her arm. Taking the blade for himself, the marine then skewered Siris before pinning her to the ground.

Isabela came in a berserker rage, and managed to actually land a few hits on the Doomguy, but was quickly defeated. A round house kick broke her back, before the Scourge grabbed her head and separated her upper and lower jaw.

Karlamine didn't even have time to attack before the Doomguy came at her with a jump. Landing on her, he put a knee to her chest before punching her in the head three times, crushing her skull.

And now, it is down to four.

For the first time, Riser felt fear at facing an opponent. But the anger at having his peerage so quickly and brutally taken apart overrode the fear he felt. Gathering his energy, he let loose a large ball of flames. The Doom Guy easily dodged the fireball, bringing out his rocket launcher.

Deciding to get rid of the small fry first, he targeted the one wearing a kimono, using the lock-on feature to make sure he doesn't miss. As the three missiles fired and homed in on her, Mihae tried her best to run away. Her dodging and evasion is for naught though, and soon she is blown to pieces by the powerful explosives.

He tried the same trick with the one wearing the cape, but she threw out an explosive which brought down all three missiles. As he dodged more incoming spell fire, the marine swapped out the Missile launcher for the Gauss Cannon with Precision Bolt modification. Waiting until the caped demon stopped moving, the marine quickly zoomed in, charged up a shot and took her head off.

The last two started flying erratically while shooting fireballs at him. The marine missed several shots before deciding that if quality doesn't work, quantity will. Putting away the Gauss Cannon, the marine deployed the Chaingun and used it as a mobile turret. Hundreds of rounds flew through the air, all headed towards Ravel. She tried her best, but even she could not dodge everything. They ripped through her, shredding her wings and body. The pain made her lose concentration, causing her to crash into the ground.

In pain, Ravel could only partially lift herself before the Doom Slayer is upon her. He grabbed her by the throat before putting the barrel of the Plasma Rifle against her chest and pulling the trigger. The full auto attack is too much for Ravel's regeneration abilities, and the extreme pain left her unable to fight back. Soon, she too disappears in a flash of light.

Seeing his sister injured so gravely, Riser lost all decorum and flew straight at the one who is responsible. Doom Guy stood his ground, and when Riser came in range, activated the Heat Wave. The pulse from the Plasma Rifle not only stopped Riser, but pushed him backwards while also incinerating an arm, his wings and half his face.

Tumbling backwards, Riser finally stopped about 20 meters away. He got up on his knees while his body quickly regenerated.

Trrk-tik. "Doom Slayer, the final Demon is able to regenerate. I suggest a constant and unrelenting assault to override the healing abilities." The Marine can comply with that.

Double jumping into the air, the Marine switched to the Combat Shotgun and fired off an explosive round. The direct hit caused secondary cluster munitions to go off, further damaging and disorienting Riser, leaving him unable to dodge the descending Marine.

Putting a foot on Riser's stomach, the Marine grabbed one of Ravels legs, twisting it 180 degrees before ripping it off. He then repeated the action for the other leg. That taken care of, he knelt on Riser's chest and started punching him in the face. Riser tried to push the Marine away, but had his right arm torn off for the trouble.

The Marine keeps punching Riser, crushing his head over and over again. And though the regeneration has slowed down slightly, it's not quick enough for Doom Slayer's liking. As such, after ripping off the remaining arm, the Hell Walker took a new course of action.

Moving his knee to Riser's stomach, the Marine started wailing on Riser's chest until an indention formed on his breast bone. Putting both hands on either side of the indention, the Scourge of Hell pulls Riser's chest apart. With the beating heart exposed, the Marine quickly grabs it, pulls it out and crushes it in his hand.

This is too much damage for Riser to be able to regenerate from, and he is quickly transported out of the Arena.

The Hell Walker stood up with his Combat Shotgun and got ready once more, turning towards the school students, who had retreated back inside a building.

Trrk-tik. "All enemy Demons defeated." Trk-tik. "Energy Analysis complete. The entirety of this area, as well as the individuals before you, all exude Hell energy." The Marine got the shotgun ready. Looks like this arena needed a few more Demons killed. Trrrrrk-tik. "Incoming energy signature."

A bright flash of light appeared halfway between him and the other group. When it disappeared, what emerged is a tall, red headed man dressed in grey armor with yellow highlights, and green and white clothes underneath, and a blue cloak.

The man spoke first, a smile on his face. "Greetings Doom Slayer. I am Sirzechs Lucifer, and it is an honor to meet the Scourge of Hell."

Sirzechs stood between his sister and the Doom Slayer. Not even in his wildest dreams had Sirzechs believed this day would come. But here he is. The savagery and utter ruthlessness fit the description to a T. But more so than that, is the symbol upon the man's helmet. One he has seen in the ancient scriptures, when the Old Demons still ruled Hell.

Sirzechs had wanted to transport everyone out of arena the moment an intruder had been discovered. However, the head of the Phenex family objected, stating that Riser will be able to deal with the intruder. As such, Sirzechs could only put the game on hold. He wasn't even allowed to send in any more Devils until Riser is defeated or Lord Phenex allowed it.

So he did nothing as the intruder made himself known. The unknown male didn't talk, and at first, seemed somewhat confused. He didn't retaliate when one of Riser's pawns attacked. Of course, it didn't look like the attack did any damage, but the principle of it would matter to a Devil. But then something changed. Shooting the pawn caused enough damage to cause her to retire, something that a normal gun should not be able to do. When the now hostile intruder turned back towards Riser, Sirzechs spotted a symbol on the helmet. One he has not seen outside some very old tomes.

There are stories about this Hell Walker. Children's tales, told to keep young Devil children in line. "Be good, or the Scourge of Hell will come and take you in the night." He remembers his mother telling him that, and has even told his own son similar stories. But it was not until Sirzechs became the current Lucifer that he discovered the true facts behind the legend, hidden deep in the library.

It told the story of the Scourge of Hell, a human that defied the old Demons and slaughtered them by legion. Many of the old heroes stood before this single human and fell. And no matter what was done, no matter how hard they tried, no matter what recesses of Hell they fell back to, he would always find them, taking joy in causing them untold misery and destruction. And the more Demons fell, the stronger the being became. Not even the mighty Titan could stop his relentless assault upon the Denizens of Hell. It is only through an intricate trap and the sacrifice of hundreds was the Hell Walker stopped, entombed in Stone and Magic, hidden away at the deepest levels.

But now he is free, and in the same area as his sister. Sirzechs pleaded with Lord Phenex to teleport everyone out, but he refused. And so they watched as the Doom Slayer went through Riser's Peerage with ease and brutality. Even when Riser was being literally torn apart, Lord Phenex merely smiled and said "Maybe this will teach Riser to not underestimate his opponents. And that Regeneration is not an unbeatable power." But with the removal of Riser from the arena, Sirzechs is able to take action.

Now he waits, wondering if the Hell Walker will listen to him or try and kill him. And as powerful as Sirzechs is, legends such as he are not to be taken lightly.

Doom Slayer.

That's what her brother called the armored man. Rias and Akeno gasped, while Koneko whimpered and hid behind Kiba. The other members of her Peerage all look confused, as they were not raised by Devils and thus do not know the history behind that name.

To be in the presence of the Doom Slayer, the Hell Walker, the Scourge of Hell, the Unchained Predator, is a nightmare that all Devil children have had.

"Who? What's going on Rias?" asks Issei. Why would she be so scared if her brother is here, the current Lucifer and strongest Devil alive?

"The Doom Slayer" responds Rias. "He's a myth. A ghost story from the annals of our history, a lost tale of warning and destruction the likes of which no one living has ever witnessed." Rias gulped. "Did your mother ever tell of stories when you were young? Stories of monsters, of predators in the night who would come and try to take you away?"

Issei nodded, while Asia and Kiba, being orphans, merely shook their heads. "For us Devils, he is our boogeyman. He is the one who will take away the bad Devils and punish them. Only by being a good Devil will he pass you over, on his endless hunt for the souls of the damned." Rias swallowed heavily again, glancing momentarily at her Sirzechs. "And even with my brother here, I do not believe we would be able to get away."

Koneko whimpered again, trying to hide even more behind Kiba. Rias kept looking at her brother, hoping that he would be able to pull off a miracle.

Seeing that the Doom Slayer is not speaking, Sirzechs said "Peace Doom Slayer. We are not the Demons you have fought before. I only wish to talk to you. We may re-engage hostilities at a later date, should you wish for it." With every fiber of his being, Sirzechs hopes that will not happen.

The Marine hesitated for a moment. This is the first time a Demon has actually attempted to talk to him, other than cursing him or that they'll eat his soul. Still, he can't trust a Demon. Ever.

Trrk-tik. "Doom Slayer. My Analysis concludes that though they all use Hell energy, it is completely different from what we have experienced before." A graph opened. "The energy they emit is based on the basic underpinnings of Hell Energy, but it is neither as chaotic nor as potent as what we have previously experienced." The graph disappeared. "And even though this goes against everything you know about Demons, I suggest taking this Demon at his word."

No. A thousand times no. "I can understand your hesitation but until the tether system recharges, my Analysis of our Dimensional jump is complete or Dr. Hayden recalls us again, we are stuck here. This Demon has not yet attempted to attack us as of yet. I do not see any other viable options available to us."

Again, the Marine hesitates. On one hand, VEGA has never lied to him and has always done its best to assist him. On the other hand, it's saying to believe the words of a Demon.

In the end, the Marine decides to trust VEGA. If this is a trap, he'll just kill everything moving and move on. As many times as necessary.

So he dropped from his combat stance, lowering the barrel of the shotgun so that it is now pointed at the ground.

Sirzechs lets out a sigh of relief. "Thank you." A snap of his fingers, and a pentagram appears between the two of them.

"Shall we?"

The Doom Slayer and the Lord of Hell walked forward into the pentagram, until they are an arms lengths away from each other. And with a flash of light, both are transported out of the arena.

AN

Well, I did not plan on writing this story. At all. It came to me over Memorial Day weekend and I just couldn't stop thinking about it. I spent most of Memorial Day writing this, so to the few who actually read this, I hope you enjoyed it. I should have spent that time working on my other stories, but nooooo, this one wouldn't get out of my head.

And no, I have no plans on continuing this. Why? Because I have not read/watched Highschool DXD at all. And I mean, at ALL. The only part I read is the Rating game, and stuff on both wikis to make sure I have the names and powers correct.

The only reason I know about High School DXD is due to the story 'A Demon amongst Devils.' If you like Highschool DXD, read this story. The Crimson Lord is one of the best authors on this site. I would rate him/her equal with cywscross, the author is that good.

So, I have no plans on reading/watching Highschool DXD, so I would be unable to continue the story. As such, if anyone reads this and is inspired, feel free to take over for me.

And before anyone asks, my theory is that Hell is its own plane of existence, its own different reality. As it is an infinite plane of existence, why can't there be something completely different then what is experienced before? Their little slice of Hell is what is shown in Highschool DXD, but that doesn't mean it can't exist in the same plane as the Hell from Doom. Also, the timeline in the 2016 game is all sorts of messed up, so I put that here as well. Make what you will of it.

Also, I may have spelled Riser's name wrong. Is it Riser or Raiser? In the wiki, it is Riser. In here, it's Raiser. Meh, whatever.

Peace

Gunkatas.
