Yes, this is a Splatoon Doon crossover. In this story we are gonna pretend that Doom Eternal doesn't happen and instead of teleporting the Slayer, Samuel Hayden freezes the Slayer for 11,900 years. Doom is 100 years in the future and considering that in Splatoon lore they found a Wiiu console let's just say the flood happens in modern time.
As Samuel Froze the Slayer he went back to the ships cockpit.
He would create Demons that he would control but first he needed to get rid of the demons that were on earth.
Using the ships scanners Samuel realized that most of the water tanks that's the government kept in space were still operational.
"Vega, how many gallons will be dumped onto earth if I lower the Water tanks and release the water through the emergency hatches?" Samuel Hayden asked the AI.
"According to my calculations Dr Hayden, if you release the water tanks onto earth 10 gillion gallons will be dumped onto earth. It will take another 10,000 years for the land to dry. Are you sure you want to proceed with the opening of the tanks?" Vega asked.
Samuel hesitated before responding.
"Vega, lower all remaining water tanks then open the emergency hatch."Samuel said.
"And the surviving humans?"
"There are hardly any. Only the ones on this ship and hidden away on Mars." Samuel said.
As Samuel Hayden saw the water tanks lower from the cockpit he prayed to whatever god might exist that some demons and humans would survive.
The demons didn't expect the flood and were washed away.
A lot of humans that were hiding survived the floods.
Samuel decided to turn himself off for 10,000 years to see what would happen once the land dried.
Over the next 10,000 years, the surviving demons became smarter and not just Demlns that had a lust for tearing humans apart. They learned how to speak, something they could only do telepathically and only with a demon of their own race.
Most sealife evolved into humanoid versions of their water inhabited counter parts.
The inklings are evolved squids that used the human technology and made their own cities, technology, and even video games.
Demons were a legend in inkling society.
Some said that if you performed certain rituals you could summon these beasts.
Some said that if you wondered the woods late at knight an imp would stalk you. These legends were true to a certain extent. But the real thing you came for was the doom Slayer right? Well he's waking up.
2019 M.E. THE UAC CRYO STATION.
The Slayer woke with a throbbing headache.
He only had one objective, to get out.
The doors to the chamber were he was put in cryosleep were suddenly bursted open.
A figure walked up to his cyro chamber.
The Slayer realized it was an Imp, and it was smiling.
"It took me 10 years but I found you!" The Imp exclaimed.
The Imp used its claws to pry open the chamber.
"Now, follow me we need to get ou-" The imps eyes went wide as the Slayers fist wrapped around his neck.
The Slayer cocked his head the scum of a demon.
It spoke, and it tried to trick him.
Without a second thought the fist wrapped around the demons throat was squeezed which turned it into a bloody pulp.
Stepping out from the chamber the Slayer thought. 10 years just to die. It was pathetic.
The Slayer rushed to the open doors and found himself in a long hallway.
He scanned a chart on the wall which labeled the room numbers.
The armory was R4 and the escape pods were in R17.
Running at maximum speed down the empty hall he scanned each door.
The killing machine stopped the sprint when he reached his destination. The Slayer brought his left predator leg to the door and gave it a kick which sent the door flying into two Imps inside the armory, killing them instantly.
Stepping into the gorified room the Slayer noticed a symbol on each of body's left arms.
He bent down and saw that the symbol was the classic demonic symbol with an angel enscribed into the rune.
The Slayer would think about that later though. Looking at the armory it was picked clean.
Looking around the room The Doom Slayer saw the body of a UAC elite guard.
In the bodys hands were a combat shotgun and a EMG pistol in the other. This man went down like a badass.
Picking up the weapons the Slayer rushed out the broken door and towards the escape pods.
He manually opened the jammed door and saw a hell knight opening escape pods for some Imps.
"H-he's here!" The hell knight shouted.
He pressed a button on the wall and all escape pods were launched but one.
The Slayer pointed both guns and fired a barrage of bullets bring the Hellknight down.
The Slayer needed to conserve ammo so he put away his shotgun and kept his pistol out. Climbing into the empty escape pod and messing with the wiring to get it to launch the Slayer was back in space.
Before the craft launched a fireball from an Imp damaged it.
It must have been another demon from back on the space station.
The pod was getting closer and closer to earth and soon the pod would burn up.
Once the pod was in the atmosphere The Slayer not giving two fucks opened the hatched and jumped out. This would give him time to escape.
The Slayer passed out before he hit the ground.
"Surge he's awake!" A voice said.
The Slayer opened his eyes and saw two figures each with blue tentacles on their heads.
The Slayer thought that this was a new type of demon and punched the one closet to him in the head splattering all its guts which were suprising blue.
The other demon screamed then began to cry. The Slayer then realized the voice sounded like a child.
The Slayer assumed this another demon trick and brought out his pistol and held the trigger charging up a shot.
But the crying and pleads for mercy got to him and he threw the pistol aside.
Only then did the Slayer realize that earth did not look hellish at all.
Infact, it looked just it looked before the demons.
The two seemed to be in a forest clearing.
The Slayer was confused at the sight of buildings in the distant.
Overall the Slayer was confused at the greeness.
He was sure the pod landed in Tokyo a place he knew was taken over by demons.
The whatever it was spoke in a language he didn't understand.
The Slayer brought a hand to his helmet and pressed the translator button.
The words became clear.
"W-why did you kill him?" The voice was clearly feminine as so was the appearance.
Based on the voice she didn't look much older than 14.
The Slayer looked to the blood splatter on the floor.
His head was gone and his neck was just pulp.
The Slayer looked back at the girl and cleared his throat. Something that sounded like a rumbling.
"I thought it was a demon ." The Slayer spoke, the voice that erupted sounded more like satin that an actual human being.
The girl looked into his helmet, tears pouring from her eyes. She didn't except the thing to talk. And Demon? She was confused.
The Slayer shook his head and cleared his throat.
"He's waiting for you." The Slayer spoke. His intentions where clear to the girl as her eyes went wide.
The Slayer raised his fist with a grunt and plunged it towards the girls head.
The head turned into bloody pieces and her body flew into a nearby tree.
Standing up, the Slayer retrieved his pistol which was laying just a few feet from the boy's body.
The Slayer looked at the destruction and felt something he hadn't felt in a long time.
It wasn't anger, it was guilt. The Killing Machine realized the creatures were harmless and we're probably trying to help them and all they got was an armored fist to the face.
Brushing the guilt away The Slayer made his way through the woods and towards the city.
Inkopolis square
An inkling with long red tentacles and tan skin was standing outside Ammo knights. She had orange eyes, red lips, average weight and medium sized breasts.
Her name was Angy. Angy is an average 14 year old girl living in inkopolis. Like most 14 to 15 year olds in inkopolis they loved 3 things. Turf wars, rap, and boys.
Angy was fairly new and was yet to make friends. Only being level 9 had a way of not giving you attention.iin
She had squidpods in (yes the splatoon version of AirPods) and was listening to music.
5 hours of Turf wars straight left her exhausted a she needed to relax.
In her other hand was a can of squid cola, which actually had beer in it.
Angy smiled when her favorite song played on her playing.
I pop out at the turf war, I'm with the gang. Buts it's gonna be robbery so tuck your chains. Ima splat your girl I'm sorry, but I can't change.
Angy bobbed her head to the rather disturbing song.
"Fuck!" Angy shouted to herself because she saw a hot guy. Something about being a virgin bothered her for whatever that reason might have been.
Angy was sick of the cheap beer she was drinking so she fumbled in her pocket to find her fake I.D
That night she came stumbling home and passed out on her bed.
The next morning was the usual. Wake up, eat breakfast, walk the 2 blocks to the Square and do some turf wars.
Callie from the Squid sisters had been back for a few months now. She was missing for a few weeks and no one knew where she went. Callie was Angys favorite Squid Sister and she was miserable everyday she was gone. With her back it seemed nothing could go wrong for her.
That all changed when she tripped while walking to grizzco.
Angy had fallen on someone.
When she looked she saw the sewer grate was wide open.
She poked her head through and saw a blue squid that had barley any of its color left.
The person changed to their bipedal form revealing and old man that was atleast 120 with short blue tentacles, a short white beard, and almost colorless eyes.
"Bucko, down here before anyone sees you!" The old man said and he walked through the sewers.
Angy was outright confused. She thought for a minute then decided to see what he wanted. If he had a group of younger inklings that would try to rape or mug her she always her splattershot mini (the pistol equivalent of the splattershot)on her at all times.
Quickly reverting to her squid form she dove into the grate.
When she reached the exit she found her selves in a canyon of some sort.
She was on some type of floating island it seemed.
Looking ahead of herself she saw the old man next to a small shack.
He had his back facing Angy and appeared to be looking at something.
He turned around when he saw her.
"Now, before you ask my name is Captian Cuttlefish of the new squid beak splatoon!" Cuttlefish exclaimed, pointing his cane in the air.
Angy let him speak.
"I watch everyday to find the look in someone's eyes, the look that tells them they are ready."
"Ready for what?" Angy curiously asked.
"To become an Agent of the new Squid splatoon!" The cap'n exclaimed.
"Agent? Why me?"
Cuttlefish walked a few steps foward before resuming.
"Because young one, something terrible as happened." Cuttlefish said, his old eyes turning into a look of sadness.
"Go on."
Cuttlefish sucked in a deep breath then continued.
"Yesterday a pod of the some sort crashed in the forest 4 miles south of inkopolis. Next the pod were the bodies of two inklings. Their heads were reduced to pulp and the females body was msngaled and slumped onto a nearby tree. Whatever came from the pod had murdered those children with its own hands. Rumors say it's a demon. But the forces of hell wouldn't have been launched through escape pods, would they? Wrong, actually 4 more pods were located in a mile radius of the bodies and 2 contained the bodies of demons. The government has been trying to cover it up but we know what happened. But whatever had killed those poor children survived the crash obviously uninjured. There was no blood that wasn't blue like the empty pods found. It wasn't a demon. Now I've located whatever this thing was thanks to agent 3 and agent 8." At exactly the same tune he said this a male inkling with yellow tentacles and a female octoling came out of the half kissing and half naked.
They both fell on the ground.
"What is going on here!" Cuttlefish shouted at the two which faces were red.
The male was trying to cover the shocked females breasts which just made her moan.
"Oh pappi SQUUEZE!" The female octoling shouted.
Angy recovered from shock and ignored it entirely.
"I assume these agents found whatever it was and also like having sex in your shack?" Angy questioned.
Cuttlefish glared at the two.
"Agent 8 is most likely drunk. As for agent 3 he was just going with it to make her happy. I HOPE!" Cuttlefish said, glaring harder at the couple.
"S-sorry sir!" The male exclaimed and rushed agent 8 back inside.
"As I was saying, if you want to become an agent, I will task you with taking down whatever creature this is down. So, are you in?"
Angy thought for a second. She then smiled and nodded.
"Sure, got nothing to lose, plus killing kids is totally wrong."
"You are now officially agent 9 of the New Squid Beak Splatoon!"
The Slayer stumbled through the alleyways bordering the city.
The main things he wondered was why the land was normal, what the fuck are these things, and why the fuckity fuck those demons spoke.
The Slayer took a moment to sit on the dirty floor.
Unholstering his shotgun and cocking it the Slayer thought.
He didn't have to kill them, but he was sure he wasn't normal to them. They would most likely lash out and attack, something humanity did when they saw something they didn't understand.
Then there was another issue. The Slayer wasn't a human anymore. If he were to make peace with these creatures he would have to act like a human again, something he could do if he were to be death of hell itself.
Looking at his weapon, The Slayer wanted to use it, to dance with it and make hell bow to it. Something his great great grandfather BJ Blaskavich did to nazis. But the Slayers job was more enjoyable. Instead of killing the dumbasses of the human race he was taking on hell itself.
The Slayer was part of a family of badasses. Even his great great great great great great great great grandfather which used magic (reference to hexen if anyone reading is a big ID software fan) was a badass. Hell, BJ escaped castle Wolfenstien itself.
The Slayer knew he would become the badass of the baddasses and would kill anyone who pissed him off. He would travel to heaven if Jesus tried anything (totally not happening). But the man in the predator suit had no time to think about the fun he would have. He needed to get through this city and find the demons and tear them apart.
Standing up the Slayer slowly walked through the ally's, careful to run into anyone taking a smoke in the ally.
Fortunately that didn't happen:
Unfortunately the Slayer felt someone watching.
"Your going to die" The Slayer said to the air.
Upon saying this something hit his visor. Something sticky, something red.
Using a free hand the stuff was wiped off and his shotgun was out.
Instead of more shots being fired, the figure jumps from a low building and pulled out a knife.
The Slayer scoffed as the figure ran towards him.
The killing machine was about to grab the figures arm and blow it's stomach out with the combat shorty when suddenly the fiv fire shot the ground past his legs with the red substance.
Suddenly they disappeared and reappeared behind them.
Two knife stages connected with the Slayers back and he fell foward.
Confused on how a knife could do that but staying on guard the Slayer shut up and fired a shot to to the figure which was a female of the same species as the girl he had killed.
The pellets connected with her stomach and pain came from her mouth.
The armor seemed to be broken but shelled her from the blast.
The girl took out a strange device and threw it.
It started to swim towards the Slayer.
The Slayer was distracted and shot at the strange device which gave her time to. To pull of his helmet which required a jump due to him being 6,6 and her being like 5,4.
She dropped the helmet as soon as she saw the face.
The face was blistered and filled to the brim with scars. His expression was rage filled and had bloodlust in his eyes.
The female shook off the shock and threw the knife straight between the Slayers eyes.
The knife made a splattering sound as it connected with the target.
It didn't kill him, not it. It just pulled it out and tossed the weapon away.
The Slayer slowly walked towards the girl who was on her knees and was filled with shock.
She began to cry.
The Slayer bent down a few feet from her and spoke.
"I won't slaughtered you. Not like the blue ines." The Slayer said.
Angy scanned the Slayer for a hint of trickery but found none
She didn't know what to do, what to say. Her breath caught in her throat and she couldn't even form the words in the mind.
After a minute she released a breath she didn't know she was holding and started to cough.
Realizing the Slayer hadn't moved, she spoke.
"Wh-what are you?" She asked looking into the Slayers eyes through his visor.
"The Doom Slayer"
