DOOM DXD

The Demonic Fallen Angels

For people who care about the canon Devils. Doomguy or John has a problem with demons especially if they involved occultism or pentagrams or zombies which he kills on daily basis like his everyday chore. Since he consumed hundreds of power-ups over the course of the game, his body began to reach the limits to the max as he was exposed to ancient demon souls which also made him powerful as it now. And Highschool DxD Devils and Doom Devils\Demons are different but they are still demons if you look in the other way, for him anyways.

You want this to be continued? Well here's it is!

A park on a Japanese town

Late Night

Doomguy or John was resting at the local park since he can't seem to find a place to stay as he doesn't understand Japanese or Chineseto talk the locals here. He's a space marine who kills demons for a living, not a civilian or a tourist who waste time taking picture of people dressed in weird clothing's and unrealistic hairdos that people seems to like in this world. John prefers brutal demon-killing action than talk since he never spoke during his time on Hell since his first insertion at the Mars Base with all the people turned into zombies or demons populate the base, he has none to talk to.

He sighs as he thinks about living after the demons were eradicated from this world by his own hands, what will he do?

'Ah, even a badass demon-slaying space marine needs some rest too.' John as he relaxes out at the park bench outside waiting for something to happen.

Suddenly a boy runs from someone and was cornered by a Fallen Angel

"Help! Someone help me!" Said by a boy whose name is Issei as he tried to escape the Fallen Angel.

The Fallen Angel threw light-spears at Issei which hits him at the legs crippling him.

John saw the whole thing unfolding as another species of demons needs ass-kicking with brutal finisher. He then wore his helmet and drew his futuristic M9 pistol and shot at the angel at the limbs which also provokes him to attack John and stopped attacking Issei

"So a mortal dares to fight me? So be it, the devil has to wait." The fallen angel attacks John as his black wings fluttered and proceeds to skewer him with light-spears. John dodged his attacks with inhuman speeds that rivals of a high ranked Devils of his physical abilities. "Impossible! No human could ever move that fast!" The fallen angel began to spam his light-spear to overpower John and charges at him in attempt to kill him in melee battle.

"Too slow you moron of a demon!" John taunted the angel and shoots his pistol at him which also impossible to evade or deflect as it was propelled with unknown futuristic technology and a bit of demonic energy that made bullets travels instantly with no decrease in accuracy at all. The bullets hit the angel which also made him feel pain as he used a non-magical weapon to defeat him. John began to switch to his chainsaw as the angel approaches at him at full speed. He then did the same as him as he ran to the angel and started his chainsaw.

"BRING IT ON SPAWN OF HELL!" John shouted at the angel and jumped at him by using his newfound demonic abilities that he earned back in Hell. He then jumped towards the angel and thrust his chainsaw at the angel which he dodged it without effort. John began to switch to Super Shotgun as flying enemies are best used with shotguns. John taunted the angel more as he fired his shotgun which also impossible to dodge even with supernatural agility.

*KABAM*

The angel was hit with hit-scan bullets that the shotgun fired from. It seems his weapon also affects the supernatural as they can be killed with it despite being a mortal weapon. John began to use his Soul Cube at the fallen angel to chop the demon apart and consumes his soul via Soul Cube.

"NO! This can't be happening! I've been defeated by a mortal no less?" Shouted by the angel's final words as the Soul Cube chopped him up into thousand pieces and his soul being drained by the cube. John then receives the power of the fallen angel's soul, making him powerful and deadlier than before.

"I'm a badass demon-slaying space marine remember that!" John taunted now dead fallen angel.

The boy known as Issei saw everything and was terrified at the man's display of brutality.

(Note: Issei is a Devil now which means John can understand him somehow thanks to Devil's universal translator magic)

John saw a teenaged boy who somehow wounded at the angel's attack. He began to approach the kid with blue potion in hand.

"Stay still kid, I don't know what he did to you but sure that wound would kill a human being in one shot and you survived?." John throws the potion at Issei who cached it and asked.

"What is this potion?" Issei questioned

John answered "It's a healing potion. You could say that it can heal you like in video games that you kids play." Issei looked at the blue bottle that was written in demonic language that labeled 'Healing Potion' on its front.

Issei began to drink the potion and his wound healed as his devil powers assisted the healing process. He began to thank John for saving his life but he was away.

A portal appears at the park and spawned Rias herself. She began to look for Issei as she was her new recruit and wields the Longinus class Sacred Gear that is capable to kill gods and help her from Phoenix's attempt's on marrying her.

She then saw Issei who is laying down on a bench still wounded from the fight.

"Issei, are you alright? What happened?" Rias asked Issei.

"Club Leader, I've been attacked by a fallen angel but was saved by a man who has a Sacred Gear and killed the angel, taking his soul too." Issei explained.

"Do you know what he'd looked like?"

"None, Club Leader, as his face was covered in a motorcycle helmet after I saw him, but he was in a thick garment covering something." Issei fainted from apparent blood loss from the attack. Rias carried him back home and thought on the fallen angel's killer.

'If that person didn't use magic then he might be secretive about it and not being detected by my familiars. Strange, who is that person killing Fallen Angels at that time."

However Rias didn't know that she's being watched by Doomguy or John somewhere.

John was hiding in the bushes watching from afar from Rias's location. It seems that this boy has connection with the devils apparently as Rias appeared from the magic circle with pentagrams on it which further reinforces her connection with the devils in this world.

'Shit, that boy was her servant? I should have killed that demon-lady when I have the chance." John moved away from the park and wondered around in the city's lesser known parts finding more demons to kill and consume.

Outside of a church

Late Night

John was running around the city's outskirts looking for demons when he saw an ominous looking church on the sidewalk.

'This church looked unholy and abandoned enough for demons to live here and converge here. Well it's about time to rip their guts and free this planet of demons and crow-men.' John entered the church and was armed with a Minigun. He then kicked the door and saw an empty church with ruined benches and defaced statues and a broken cross.

"Well it's time to cause chaos and demolish this demon's lair." John smirked and drew his Rocket Launcher ready to break apart of this unholy church.

To be continued.

Well that was expected from our crazed badass space marine as he found the hideout of the Fallen Angels, there will be more blood and gibs at the next chapter so hold your horses as he will break the Canon of this series by killing important characters from Highschool DxD and killing even more Devils/Fallen Angel/Angel or any deities that looked evil and demonic.

If you don't know what Doomguy looks like. He has brown short hair and a pit-bull like face that grins when he got a new weapon or kills hundreds of demons in his line of sight. Just search Doomguy and the result will appear for you to visualize him killing Fallen Angels and their cultist followers.

Stay tuned on DOOM DXD

I was going to make it into Painkiller crossover but it seems it was less popular than Doom in this site. Still, Doomguy will not stop until he killed everyone on the church.

And then John was a demon, a half demon to be exact since he'd consumed the souls of the demons by using the Soul Cube as his device for gathering souls and using them, expect him to be more powerful as he kills more supernatural entities.
