DOOM DXD

Prologue

A Different kind of Hell

This story will be one-shot unless given with reviews to continue on as working two stories makes me feel more lazy and stressed


Icon of Sin's Chamber

Unspecified Time due to distortion of the space

Doomguy finished the fight by killing Icon of Sin's forehead with a BFG with one shot, exploding its brains as it tried to spawn more demons to kill Doomguy. He already concluded this place has no exits or secret passages as the exits are blocked by debris and too high for him to climb or jump.

With no hope of escaping Doomguy began to say his final words.

"The world is better without demons lurking around the world anymore." Doomguy as he accepts his final fate as the savior of the world and becoming an unsung hero as everyone on Earth is dead somehow or turned as a zombie.

What he didn't know as he closed his eyes to expect him getting crushed by falling rocks and skulls, a great flash of light engulfed the area, saving him from imminent doom.


Dimensional Rift

Unknown

Ddriag watches the mysterious vortex appearing on his realm as he saw a green armored human invading his privacy who is somehow wounded from his last battle with the demons of Hell, from his dimension at least. Ddriag used his godly power to see through the man's memories and why he's here.

"Hmm, a mortal defeated the Old Demons with him alone. I wonder if he partook in the Great War himself with all these weapons and his uncanny skill in defeating the demons of his world. He also possesses a sacred artifact of unknown make from his world. I wonder if he's going to kill all Devils as they have changed from their barbaric ways to civilized one." Ddriag shrugs as he sent Doomguy into to mortal world as he was being converted into a Sacred Gear.


Abandoned Warehouse somewhere in Japan

Night

Doomguy woke up from his apparent death in Hell. It seems he cheated death once more as he was alive and somehow ends up in Earth. His weapons are also present including the Soul Cube which helped him to defeat Cyberdemons with ease without using his precious BFG. He also feels someone is watching him as he looked into the warehouse with his shotgun drawn to the horizon.

"This keeps better and better." Doomguy as he waited potential demon to pounce him.

"Khekhekhekhe. You are my easy snack for the night." A spider-woman-demon prepares to eat Doomguy.

"Fuck you." Doomguy shoots the spider-woman with shotgun shells hit the demon in the head.

"Fool! Mortal weapons won't hurt me! PREPARE TO DIE!" The spider-woman-demon braced for her attack with unholy laser blast.

'Guess the demons here are tough enough to be resist bullets. Well then, time to bring my chainsaw.' Doomguy switched to his chainsaw and proceeds to dismember the demon with brutality.

The demon fired her unholy laser blast which also been evaded by Doomguy's inhuman speed as he sunk his chainsaw into the demon's torso and started it causing the demon's body to bleed uncontrollably as the chainsaw ripped apart the demon's torso in half. Doomguy wasn't finished though as he slashes the demon's head and then stomped with greater force, crushing the demon's head and ripped apart of the remaining pieces of the demon's body for a brutal finisher that he always does at the demons of all sizes. Doomguy began to use the Soul Cube to clean up the remaining gibs of the demon as he was in Earth, people might get freaked out seeing a demon up close.

Doomguy began to wonder why demons already speak now that most of them grunts or roars as they saw him. He exited the warehouse to see his new surroundings.


Docks

Night

Doomguy saw his surroundings as he looked around and saw no apparent demon invasion like his world does, it seems after killing Icon of Sin he was transported into a different dimension as the demons already has that kind of power enough to make normal humans insane. He was different however as he consumed Ancient Souls (Invincibility power-up and Mega Health) since his time on Mars and Hell, making him sort a demi-god as he absorbed their powers and made him stronger as he can punch a Cyberdemon without a scratch. He also ponders if that demon was a hidden one, many of them still lurking in the shadows waiting helpless humans to prey on. Doomguy began to wrap his armor with rags found at the warehouse to prevent people from freaking out and removed his helmet storing it into his hammerspace reviling his face.

(He looked the same guy that you see in Doom. No needs for exposition if you played Doom or do I have to explain it?)

He began to find more demons by going into the city deeper.


City Streets of a Japanese city

Late Night

Doomguy has trouble in understanding Japanese as he never heard of it during his duty as a space marine on Mars or anything. It seems that the buildings are different compared to his world as they don't have any spaceports or floating cars at that time, which means he really came from a different dimension. He also mistakes Japanese letters around the buildings as Chinese because they are all the same according to him which makes it even harder to understand.

Since he has no currency of this world he began to run everywhere at full speed hoping to find an abandoned place to stay for the night, when he realized that he never got tired during his time on Hell and Mars. He still wants to find a hideout though so he ran very fast as he finds a new place to stay from this new world.


Rias's Peerage POV

Warehouse

Late Night

They received a request to hunt and kill the Rogue Devil as they found their target at the warehouse which the target waits there. They did not expect that they were late as they saw bloody floors with entrails left by Doomguy's brutality at the Devil with the body were nowhere to be found as the Soul Cube destroyed the rest of it.

Akeno began to speak.

"Ara, Ara. It seems someone killed it before you even kill it."

RIas was baffled as they never heard or saw someone killing Rogue Devils alone without them detecting their presence, which means a stealthy person killed it and did quite a mess too.

"Let's go back at the Occult Club for a meeting. We have a new potential of a member to recruit, and investigate our mysterious killer." Rias's peerage complied and returned to Kouh Academy.


No single soul have ever thought about DOOM x Highschool DxD starring Doomguy as the main character as he was transported to a world full of supernatural which he kills them in most brutal ways . This story will be one-shot until further notice and might be removed as I'm too lazy to think more ideas to move on and hated cluttering dead fics around.
