A/N (Post chapter authors note for extra info since ffn story info has a character limit): This is an M rated fic as it contains extreme violence, including gruesome scenes of death, bodily mutilation, usage of guns and other weapons. swearing, some smut/sexual scenes and scenarios which have detail to them, and other mature themes. The bio says canon pairings so the obvious one being Harry/Ginny (its says in the tags anyway) with background Ron/Hermione and other pairings are mild and not mentioned much.

This is a crossover however if you are an HP fan, you dont have to know much about the SCP foundation as a fair bit is explained throughout the fic.

please enjoy my first crossover!!!

The Rise of SCP-1853

For many decades the SCP Foundation had been working tirelessly to keep the world from being ravaged by many anomalies, receiving funding from foundation projects and from many large government's it functioned to protect humanity.

it was a regular day for many researchers as some containment procedures were updated or changed, tests run to determine how volatile, sentient and powerful some of them were. For the researchers posted at site 1853-A it was a normal day at first, monitoring the peak of Scafell Pyke, the highest point in England where water ran, the site was relatively small and only housed a dozen researchers and facility guards, including the site director and Head of facility protection management. it was around an acre of space built of brick and mortar and concrete. The site served one purpose for the last 32 years, to monitor Euclid class anomaly SCP-1853, pending Euclid-Thaumiel classification.

Not a lot was known of SCP-1853, but what is known is incredibly vital to the SCP foundation. SCP-1853s sole purpose was to protect humanity at all costs from anything other than itself. It is believed that SCP-1853 has existed since around the time of 2 AD but others believe that SCP-1853 dates back as far as 2000 BC, when SCP-1853 becomes active it exits a stone coffin with unidentified rune like markings and proceeds to burrow itself out of the ground and onto the surface, SCP-1853 is always successful at exiting its coffin, once it reaches the surface it will remain idle for around half an hour to an hour at times. This is believed to be a homing in process where all of SCP-1853s vital functions begin and it gathers information on what has happened since it last laid dormant and what its target is. Once this process is complete, a shotgun identified as an FN pump action shotgun will materialise into its right hand, it is believed to have an endless pit of ammunition as a result of SCP-1853s extra-dimensional properties.

SCP-1853 is also written by scribes that have documented its presence to possess a large blade of "the sun" due to its bright, blazing red colour and incinerating anything it comes into contact with, SCP-1853 can dematerialize and rematerialize all of its current arsenal. SCP-1853 is measured at around 6 foot and 7 inches, its weight is unknown due to its black exoskeleton which is made out of an unidentifiable but believed to be indestructible material. It is known to possess a large amount of strength due to its body and its exo suit. SCP 1853 is able to create portals that allow it to move around effectively, though it takes around 5 seconds for them to form and requires a large amount of concentration to create them.

After its homing in phase, SCP-1853 will seek out its target, having an innate sense of its location but not a specific location, but more of a general location of where their target is. Upon the target being defeated, SCP-1853 will journey back to the peak of Scafell Pyke, it will use a portal to travel 100 metres away from the point where its coffin lays and travel the rest of the distance on foot, looking to become slowly more tired as it gets closer to its resurrecting point, the coffin will anomalously float until it is right below SCP-1853, which will then lie facing upwards, its arms rested with its sword, at this point the ground begins to crumble and re-bury SCP-1853s coffin.

One of the staff, Junior level 1 researcher Dr. Joseph Bradley was busy filling out some papers to do with his training at the SCP foundation, his quarters had a window that viewed directly to where SCP-1853 was currently idle, new seismometers had been put in place to monitor SCP-1853 activity that wasn't visible unless you could see through all the mud and dirt as the storm kicked in, it wasn't easy living atop of Scafell Pyke but it was designed to be suitable for isolation, they had area where food was grown and harvested and communication towers so that they could alert upper command and even 05 in the event that SCP-1853 became active.

He glanced at the monitor and watched the steady beeping as a laser image was shown of the coffin, thermal imaging was also shown and there was just, nothing.

Dr. Bradley rubbed his eyes, already feeling the effects of tiredness, something he was about to do was turn in for the night, his thoughts and mind were drawn away when he felt something, he turned back to the monitor and did not expect what he saw. Movement

The machines beeped loudly as movement was detected, at first it was what looked like SCP-1853s hand, it clenched into a fist and smashed the ceiling of its coffin. Dr. Bradley dashed out of his quarters as the alarm began to blare and the words blared around the site made everyone alert.

"SCP-1853 HAS BROKEN OUT OF IT'S CONTAINMENT!!!"

*

He had to get out, he thought, and with a clench of his fist, SCP-1853 stuck the underside of the coffin lid, cracking the stone, he struck again, and the stone crunched and crumbled away, grunting at the impact for all the dirt and muddy earth that filled his vision. SCP-1853 began to crawl its way out of the mess it found itself in, its exo suit gearing into life, the sounds of a blaring alarm filed his ears as it the storm raged on as well.

The facility guards were stationed in a small circle around thirty-five metres away from the point at which SCP-1853 would arise, their SCP foundation standard rifles pointed ahead of them, they were ordered too only keep an eye on the anomaly but not to open fire. The earth above where SCP-1853 began to climb up rippled and bulged before a hand with the unknown black material surrounding the back of his hand rose, flexing its fingers as it felt the biting cold of the rather stormy night.

The head facility guard spoke into its radio, informing the rest of the site that they had officially spotted SCP-1853, he was ordered to remain in his position and that the information of SCP-1853s breach had been sent off to the 05 council.

SCP-1853 broke through the surface completely and slowly got up, almost testing its balance, the last time it had been active was around a few hundred years ago and it would need to be documented, it then remained in its original standing position, firmly looking at the ground.

"Team, command advises you to approach the target." came from the head facility guards radio.

The head facility guard ushered for five of his men to approach SCP-1853, the remaining seven were to hold their positions, the team slowly approached SCP-1853 and waited patiently for any signs that SCP-1853 had exited its homing in phase. it was around half an hour before SCP-1853 turned and looked at the head facility guard and spoke.

"I know you will monitor my actions and whereabouts," Began SCP-1853, its voice echoing through the stormy night as the rain pelted them, and lightning flashed. "But you will not interfere with the people I am helping, for a once normal human has become so inhumane, I am required to step-in." he finished with a steely glare.

Without waiting for an answer, SCP-1853 turned around and with a look of concentration, a portal appeared, and it materialized its FN shotgun, holding it by its side with its right hand. it held up the gun to its chest, cocked the shotgun with his left hand, almost like it was preparing to walk into a fight, and stepped through the portal. The portal soon disappeared and the whole site was left in disbelief.

A few months earlier, we go to harry potter at the Dursleys)

The hottest day of the summer so far was drawing to a close and a drowsy silence lay over the large, square houses of Privet Drive. Cars that were usually gleaming stood dusty in their drives and lawns that were once emerald, green lay parched and yellowing - for the use of hosepipes had been banned due to drought. Deprived of their usual car-washing and lawn-mowing pursuits, the inhabitants of Privet Drive had retreated into the shade of their cool houses, windows thrown wide in the hope of tempting in a non-existent breeze. The only person left outdoors was a teenage boy who was lying flat on his back in a flowerbed outside number four. Harry potter, a young man who had been given what could be considered as the worst hand that life had dealt him, just last year he had been forced into a tournament for wizards and witches three years older, with more experience and better knowledge than him, despite winning it, there had been losses, Cedric Diggory had been murdered by Peter Pettigrew under Voldemort's orders and he had been used in a ritual which involved the use of his blood to resurrect Voldemort, or has he was known to only by Harry, Ginny and Dumbledore, Tom Riddle.

Ginny was another person playing on Harry's mind, there was something he felt towards her that confused him greatly, he loved Ron and Hermione, they his best friends in the whole world, he was good friends with Ginny, but he often found himself thinking about her ever since she stopped acting so shy and started showing him what she was really like. To him, she had just been Ron little sister.

His pleasant thoughts were interrupted however when he was ordered by Uncle Vernon in a not so nice way to get his freak backside into the house and make dinner as "poor duddykins was hungry".

The fat bastard.

Harry stretched his back muscles as he slowly got up off of the grass floor, which was now yellowing as well due to the heat and it hadn't been the most comfortable, and this was coming from someone who lived under the stairs until he was eleven years old.

Harry got round to helping make dinner and eventually went up to his room as he knew he wouldn't be fed anything. When he entered his room, he grabbed the two photos, one was of his parents that he was found in the photo book Hagrid gave him in first year, the other one was Harry with the Weasley's at the World Cup, with Hermione as well, Harry glanced at Ginny in the photo and a smile formed on his face when sh egave a brilliant smile, her flaming red hair moving about.

He put the photo back in his chest of draws and decided it would probably be best for him to get some sleep, his relatives seemed to be in a good mood and he was thankful to take the few extra hours of sleep.

*

Over the next few days, Harry continued to spend his day's lying either on the front lawn outside of number four Privet Drive, or on one of the benches at the park nearby. Durley and his gang sometimes hung out there and thankfully they had been ignoring him so far which allowed his thoughts to wonder and for him to clear his mind, it was days like these he cherished despite the horrible guardians he had. At the end of the day he was still a nearly fifteen year old boy who unfortunately was constantly worried with the looming threat of Voldemort and he wondered whether people truly paid a thought to how difficult it was mentally being famous for accidentally obliterating Tom Riddle at the age of one and having to deal with losing his parents, and his godfather being thrown in jail.

He had sent off letters to Ron, Hermione and even Ginny, all asking what was going on.

He only recieved a letter from Ginny and he eagerly began to read it.

Dear Harry.

I know you are wondering, where are Ron and Hemrione's letters, they don't exist. Dumbledore forbid us to send letters to you and said to keep this whole thing a secret but I feel it is wrong to leave you in the dark.

We are currently staying at your Godfather's family home, I can't reveal the location because I'm not the secret keeper and I would get in the shit if I did.

The truth is that ever since Tom returned, Dumbledore has recalled an old group known as The Order Of The Phoenix. During the first war, it was setup to combat Tom and his death eaters and disbanded after he was defeated by you, obviously. However with recent events we were all forced to move here for the summer and neither I nor my brothers or Hermione, know anything they are discussing during the meetings.

I hope this finds you and we all are worried about you, I know it isn't easy and that I cannot fully know what's going on in your mind but if you need to talk, or even send a ranting letter, I'm only an Owl away.

Love Ginny.

Harry smiled slightly, always the troublemaker of the group she was, at least he had some idea and he couldn't fault his friends, he would definitely have to feign ignorance a little when he arrived, infront of the order members anyway.

He stared back up at the bright, yet cloudy sky, he felt like almost nodding off when he was interrupted by the sounds of Dudley's friends howling and laughing at something as they approached him.

Harry raised himself up just intimate for Dudley to appear and jab his fist into Harry's face, thankfully he didn't have his glasses on but a bit of blood came out of his nose.

"Oi, potter," began Dudley. "Were you eavsdropping on my conversation?"

"No." Said Harry simply as Dudley slammed his fist into Harry's gut, winding him.

"Don't lie to me you piece of shit, it doesn't concern you." Said Dudley before turning away, but Harry couldn't resist a jibe at the jackass that was his cousin.

"Is it that popular girl at your posh school," began Harry knowing who he was talking about, a girl Dudley had a bit of crush on. "Does she know you still get called ickle-duddykins as if you are only four."

Dudley and a look of fury on his face and piers polkiss said "Oi dud mate, wanna beat the shit out of four-eyed prick again?"

Harry groaned knowing he was about to have the life knocked out of him, he would hopefully be able to leg it somewhere, if he came back home bloodied and bruised, Petunia would complain about him making a mess.

"FIGHTS ON LADS!" said Dudley as he turned to face Potter, who had already turned and ran for his life.

Harry was panting as he took off full sprint, Dudley and his gang were already on his heels, but years of doing this taught Harry some tricks. He leapt over a stone wall, using his arms to push and hold is weight over, being skinny had its advantages as Dudley couldn't keep up with the pace of Harry.

One Dudley's mates cut him off and Harry ran straight into him, hitting him in the stomach and knocking him out of the way, though not enough for him to trip over his foot and scramble back up as Dudley reappeared.

"Come on Dudders, use those legs you fat bastard." Shouted Harry as he ran towards one of the tunnels which led to another part of the village, where Privet Drive was, there was a bridge overhead as cars moved along.

"GET THE ANNOYING SHIT!" Ordered Dudley, panting as he stumbled, trying to keep up.

Harry kept running, his legs were burning and he was losing any energy he had left, he really did not want to have to deal with this. He kept moving though taking sharp turns and avoiding some of the random people, including Mrs. Figg who was frightened to death as Harry nearly tackled her by accident.

Eventually Harry slowed down leaning against a subway tunnel as he tried to catch his breath, his lungs felt like they were on fire and he felt the sudden urge to cough and he did, wheezing as air re-entered his lungs.

"Fucking hell." Harry panted as he walked slowly forward, aiming to get back to Privet Drive.

After a good few minutes, Harry felt much better, though he knew his legs would be stiff as a brick the next day.

It wasn't like it could get any worse, but that changed when Dudley appeared round the corner, he mates behind Harry as well as they turned the corner.

"Thought you could lose us, dickhead." Said Dudley, stalking up to Potter.

"Well, your fatarse fell over a few times," said Harry fixing him with a steely glare. "I consider it a win."

"Well you don't get your hopes up, your here now and I'm going to beat you so hard you'll be crying to join your dead good for nothig parents." Said Dudley and his mates laughed at his insult as the knew that would hit a nerve.

And it did, Harry could feel anger bubbling up inside of him. It was cut short when they heard the pouring of rain outside, and the lashing of thunder and an unmistakable chill filled the air.

"Come on Dudley lets go." Said Piers as he began to feel like he had been shoved in a freezer.

They left though Dudley stayed there, a look fo fear on his face especially since Harry had his wand out.

"What are you doing?" Said Dudley worriedly.

Harry shook his head and then he felt them.

Dementors.

Suddenly Harry was spun around by the scruff of his collar and was being hoisted up by a Dementor, the guardians of Azkaban that could suck the soul out of a human, making them an empty husk of a human, Harry wfelt his airways close as he struggled to breath, the cold now on his lips as the air was sucked in and the Dementor was preparing to kiss him.

Dudley couldn't see what was happening other than Harry bing hoisted up. "Go" rasped Harry as he tried to raise his wand, he turned and ran but slipped over as he felt a wave of cold and dread rush over him, he slipped and smacked himself in the back on the floor as Harry watched a Dementor descend on Dudley and it begin to reach into kiss him.

He turned his attention to the Dementor now, its face mere inches from his lips, heeeked out the words "Expecto Patronum." And a light shot out of his wand.

The effect of a half decent patronising combined with the point black range, sent the Dementor reeling backwards as Harry sent his full corporeal patronus at it, causing the Dementor to retreat completely.

Harry turned to the one over Dudley and pointed his wand at the Dementor and shouting "Get it!"

The Stag Patronus charged at the dementor, its glowing, white antlers stabbing the Dementor, causing it to reel back and float away before fully retreating, seeing its next meal to be a lost cause.

Harry breathed a sigh of relief, he needed to get Dudley back to Privet Drive, knowing he would have a lot of explaining to do. He hauled Dudley up onto his right shoulder and Mrs. Figg waddled over.

"Harry dear, what happened?" Asked the older woman.

"Nothing, I'm fine." He said

"I saw those Dementors and then your patronus chase them off." Mrs. Figg added.

What then ensued was a long conversation back to Privet Dirve as Mrs. Figg filled him in on everything about who she really was, a squib who was there to keep an eye on Harry.

They stopped outside number 4 Privet Drive. "Well you better get him inside, and no doubt you'll be in an undeserved world of pain." Said Mrs. Figg with a sympathetic look.

Harry dragged Dudley's arm over his shoulder again as he felt his muscles become exhausted pulling the lump that was his cousin to the door. He rung the doorbell as it was locked.

Aunt Petunia opened it and her mouth gaped as Harry dragged Dudley inside.

"What have you done?!" She hissed.

"We were attacked by Dementors." Said Harry as Petunia gasped and paled. Vernon walked in and growled, anger boiling inside him.

"WHAT HAVE YOU DONE TO MY SON BOY?!" he bellowed grabbing Harry by his collar and lifting him up.

"I didn't too anything, I saved his life." Said Harry, somewhat desperately.

"AND IM SUPPOSED TO BELIEVE YOU." Shouted Vernon as swung his fist at Harry's face, blood spurred from Harry's nose.

"Vernon." Said Petunia.

"What?" He asked before he saw that Dudley was awake.

"Harry?" Petunia asked calmly though she seemed scared that what she was thinking was correct. "The dementors guard the wizarding prison don't they?"

Harry nodded, Vernon looked between them in confusion and anger. "How do you know that Petunia?"

"My sister, talked about it," said Petunia "Harry, go up to your room, Vernon get me some warm blankets for Dudley."

Harry didn't know what to do and Vernon nodded. "Well boy, up to your room as your aunt says." Vernon said to him much quieter and with less anger.

Harry made his way up to his room and found a letter on his bed, with the seal from the ministry of magic. He sighed, knowing he was now in the proverbial doghouse. He picked it up just as Hedwig returned with more letters.

Dear Mr. Potter

Under the sixth decree of the statue of secrecy from the laws of the ministry, you are hereby expelled from Hogwarts and will have your wand snapped by Aurors who will arrive at your home.

Any resistance will be met with increased disciplinary action.

Sincerely

Miranda Hopkirk

Secretary to the Head of Department of magical law enforcement.

Harry let out a breath and felt nervous. How soon would the aurors be here to snap his wand?

And he was now expelled from Hogwarts.

He sank down on to his bed, he pulled one of the other letters from the pile and read it, it was from Dumbledore.

Harry.

DO NOT SURREMDER YOUR WAND TO THE AURORS IF THEY ARRIVE. I am currently in the process of getting you a trial as you are entitled to by the laws of the ministry, I will have some people you know pick you up and take you back to where we are.

From Dumbledore.

It had been hastily written and Harry could understand why, he picked up the others and they were from Sirius and the Weasley's who gave him the same instructions.

Guess I'm not getting any sleep.

*

Vernon had locked the door to his bedroom, he had told Harry that he, Petunia and Dudley were going to the hospital to see if Dudley was going to be okay and to get some groceries and that he was to not leave his room.

Harry couldn't sleep of course and was staring up at the ceiling of his bedroom, he felt nothing and everything in terms of emotions and thoughts, the aurors hadn't shown up and Harry didn't know if that was good, or whether it just made the night seem more ominous.

He was distracted from his thoughts by the sounds of footsteps and the rattling on his doorknob, Harry grabbed his wand and pointed it at the door, if the aurrors were here he would fight them off if he had too.

The lock clicked and the door creaked open, he saw a young woman with bright pink bubblegum hair, she looked friendly and Harry heard the voice of Alastor moody.

"Put your wand down Potter, it's only us." Growled Moody.

Harry gripped his wand tighter. "In my fourth year, during October, what curses did you teach the class."

Moody grinned a little. "Wouldn't know would I, I was trapped in a trunk by Barty Crouch Jr."

Harry relaxed a little and the woman with pink hair whipped her wand and Harry's stuff packed itself and she grabbed his trunk and hauled It down the stairs, Harry followed the group, other than Moody, he recognised no one.

"Potter, do me a favour would you and grab me a glass of water." Said Moody popping his electrical eye out.

Harry headed into the kitchen and grabbed a glass and filled it till it was half full and turned off the tap, he passed it to Moody.

Moody then dropped the magical eye into the glass of water Harry gave him as he spoke "Ever since that criminal used it in his disguise as me, its been all smeary and not spinning around in its socket properly, the stupid bastard."

Harry just nodded not sure what to make of Moody's irritance at his magical eye as with a squelch, he popped it back into his empty eye socket.

"Right less dilly-dallying you lot," Ordered Mad-eye Moody to the group as they headed out of the door. "We are going to apparate out of here back to Grimmauld place." Before he heard a loud crash as the pink haired woman knocked over the coat rack. "Tonks, you buffoon, this is a stealth operation, it means no knocking things over."

The woman called Tonks flushed. "Sorry."

"Anyway, Tonks you can side-apparate Potter back to headquarters." Said Moody.

They all headed outside and Tonks told Harry to grab hold of his arm, and the sensation of being squeezed into a tight and small tube overcame his body as he and Tonks, along with the rest apparated away.

They all landed outside a long row of houses.

"Read this Potter and memorize it." Said Moody, producing a folded sheet of parchment, he opened it and read the contents.

The headquarters of the order of the phoenix, can be found at number twelve, Grinmalud place.

A/N: Once I have finished my main fic which is on my wattpad I will be publishing the other chapters I have done weekly.
