My Hero Arachnid.

Chapter 1: Mysterious mishaps.

Little edit, I noticed that FF deleted all of my custom line breaks as well as a few words, so I went back to fix that... if you notice anything feel free to tell!

"MJ, no, it's not that I'm not happy about it! But life doesn't work like that! I don't just win at life, something is gonna come and stomp me, mark my words."

Peter Parker was on a winning streak and that made him incredibly uncomfortable.

"Tiger, you're overthinking again. Maybe you're finally getting good at this hero stuff?" Mary Jane Watson, top 10% of her class, an incredible actress, one of the most popular girls on the entire school and somehow, dating the biggest dork in her class, was also an optimist. "Life has got to give you a break sometime right? Might as well do it for our finals." She grumbled the last part, staring daggers into the book sitting on her lap.

"It really doesn't. Whatever cosmic being decided to watch over me is a sadistic son of a bit-" Before he could finish his complaints about the universe a portal spun itself open in his room between him and MJ. Reflexes grown from two years of dodging bullets sent Peter jumping to the ceiling, his web-shooters already attached to his wrists and ready to make any monster that stepped out of that see so much white they'd become color blind.

A figure stepped through the portal, wearing a gold trimmed, dark blue shirt, loose brown pants and leather shoes. On its back, a red cloak seemed to move with a level of sentience no article of clothing should have. As the figure settled in the room they could finally see it's face, a man in his late thirties, he had black hair with a single white streak on it and one of the coolest goatees Peter had seen since he helped Tony Stark in the Avengers' tower a few months back.

"Peter Parker?" Doctor Stephen Strange. Sorcerer Supreme, one of the most powerful humans on the planet. Peter had met him on the same Avengers fiasco that led him to meeting most of the team. They hadn't talked much, but the sheer aura of power the man possessed made the Spider Sense go all kinds of nuts while standing anywhere near the guy.

"Doctor? Dang it, I knew I forgot to eat my apple today." Smartass quips, the best way to deal with stress. Letting himself fall from his ceiling the teen motioned to Mary Jane so she wouldn't throw his lamp at the man who could make her into an eldritch combination of woman, tea kettle and six different goats. He also really liked that lamp.

Stephen smiled softly at the jab to his old profession before donning his serious persona once more. "I wish this was a mere visit, but I need your help." Normally the Doctor would never get such a young mind involved into his more mystical affairs but something was blocking him from finding whatever was causing disturbances in the magic of the area, and since this was Spider-Man's usual stomping grounds, he figured that a little help wouldn't be entirely unwelcome.

"But I'm just a normal kid."

Strange's eyebrow rose.

Peter's eyes darted to Mary Jane.

The eyebrow rose some more.

Peter gave him a pained look that was practically begging him to cling to any sense of normality.

Stephen's smile shattered any hope Spidey had managed to drag from the depths of his soul. "She's in your room wearing one of your uniform pants as pajamas Peter."

Mary Jane looked down and notice that she was in fact doing just that, looking back up to her boyfriend who seemed divided between pulling his hair out and smiling dumbly at her, the redhead could only shrug. "Oops?" Before returning to her reading, she had finals and Peter could very well deal with his spider stuff without dragging her into it.

"Just… Let me change clothes, I'll meet you on the roof Doc." That seemed to satisfy the sorcerer who nodded and stepped through another portal.

"You couldn't wear one of the 17 leggins you left here? I washed them just so you wouldn't have to keep bringing more."

"It's not my fault you made your costume so comfy Tiger."

The New York Harbor. Peter had only really come here twice, the first time when Mysterio first popped up and kicked his ass up and down the whole place and the second one when he teamed up with Daredevil to bring down one of Fisk's warehouses. And now he was back here, and from the flashes of green light and thick grey smoke it seemed his illusionist pal had made his way back to his place of origin.

"Wait, so you're telling me one of the guys I'm usually dealing with got a mystical artifact powerful enough to get your attention? Doctor, no offense, but you do know most of my guys are 100% psycho and if that smoke is any sign, we got possibly the second worst person that could ever have this kind of power, right?" Spidey did not enjoy the idea of Mysterio having a super powered magical thing, no matter what that thing did, that particular villain was almost as sadistic as the Green Goblin and even smarter considering he wasn't as prone to bouts of absolute insanity like Osborn.

"I'm afraid I'm not aware of such things, it's why I brought you, if it is one of your more common foes you're certain to have more insight than I." Strange had been doing a ritual for the past fifteen minutes, trying to determine what object might be inside the warehouse, finally ending his magic with a long sigh he stood from his place on the roof. "The Object seems very… determined to keep me from knowing what it is, I won't be able to determine its nature without having it within eyesight. But knowing it's smart enough to not want me near it is worrying, to say the least."

"Alright, so magical magoo that is smarter than the common tug, shouldn't be too hard right? I'll try to sneak in, stay close in case things go south." Before Strange could respond, Peter jumped from the roof, swinging closer to the building and sneaking in through one of the many holes that had been blown out of the roof in the last couple minutes. Whatever it was that Mysterio had on his person now could not mean a good time for anyone involved.

Crawling inside the first thing he noticed was the horrid stench, it smelled like someone grabbed all the fish from the harbor, left them in the sun for a week, dragged them to the warehouse and took a piss all over the mess just for good measure. The second thing he noticed as his spider-sense kicked in telling him he did not want to go anywhere close to the source of this smell, was Mysterio laughing himself mad, sitting on a golden throne. That wouldn't be a problem considering the illusionist did have a flair for the dramatic, what worried Peter was that said throne was on top of a pile of corpses, none of them human, but twisted creatures from all kinds of fantasy, Goblins, Spiders, Trolls, Faes, Elves, Dragons, Satyrs. No single culture was spared from the grotesque pile Mysterio had built his throne on.

Around the mad magician, several creatures fought to the death, using only what their myths gave them as weapons, they ripped each other apart, screaming in pain and fury the whole time. "What the…" Peter knew Mysterio to be a sadist, but nothing like this. For as smart as he was, the illusionist was never really a killer. He would severely wound people in his escapades but never went as far as outright killing someone.

Trying to sneak back out as quietly as he could to call upon the Sorcerer Supreme because there was no way in hell Peter was dealing with that mess alone, one of the creature who had been beaten down by it's mystical foes spotted him, and using its last breath and choking through the blood, pointed straight at him and screamed.

A single moment of silence, as Mysterio twisted his neck to see what had interrupt his fun was all that the teen hero had before having to jump away as the head of a dragon materialized besides his long time enemy and and shot a stream of flames at his position. The other creatures in the room completely forgot about their previous battle to chase after him as Mysterio's usual fishbowl helmet exploded in green flames and he screeched something that felt like needles made of ice were being stabbed into his brain.

Jumping away from a Satyr that was trying to impale him with his horns and swinging from a Troll's fist that was at least as big as his torso, Peter tried to hone in on the now corrupted villain. "Damn Mysterio! I always knew you were good with illusions but this takes it to a whole other level!" Not stopping for a second less he'd have one of the creatures manage bite his legs off, Spidey started webbing monsters together in hopes to hold them off until Strange managed to drag his slow mystic behind inside and help him.

"And I love the new look! Really shows how bright you are!" The Illusionist had never had any patience for his humor, time to see if breaking his focus would do anything. jumping to one of the beams on the ceiling and deciding to try his luck, Peter equipped one of his more fire resistant web fluids, and rushed towards his nemesis who seemed to gain some semblance of lucidity.

"You're a fool spider, I have transcended my petty illusions! This is my Magnum Opus! Every creature, every machine, every dream! I can bring it to reality! You cannot stop me anymore insec-hgmph!" The crazed monologue was interrupted as web struck the crazed magician in the face. "First of all, spiders are arachnids, not insects, come on Quentin, you're smarter than that." Slipping over a centaur that was rushing him Peter slinged himself towards Mysterio, kicking the madman from his golden throne. "Second, you get the power to bend reality and the first thing you do is a monster battle royale? What's this one going to be called, Monster Mash?"

After a few moments as Quentin dragged himself up, the monsters started to dissolve, into the villain's signature smoke. "Huh, guess it was actually concentration based, lucky break, maybe MJ's right." Spidey mumbled to himself starting to web up the still dazed magician. "I don't know why Strange was so worked up about you, having a magical artifact, it clearly didn't make you any more of a strategist." The stab at the man's pride seemed to break him from his daze. His eyes shot wide with fury, red seeping into his sclera, as his blood vessels seemed to explode inside his eyes.

DODGE

Peter's spider sense almost split his head open with it's urgency, making him jump back with all the strength his super human legs could provide and launching himself through the wall of the building seconds before the whole thing went up in roaring dark green flames. "Ugh… me and my big mouth." Dragging himself out of the debris the teen was just in time to see Mysterio, who was sitting at the middle of that emerald inferno, get punched by a gigantic fist make of incandescent chains.

"I apologise for taking so long Spider-Man, but I needed to determine what that anomaly was and it is… worse than I first imagined." He was worried… that was definitely not a good sign. Even more so since Mysterio was already picking himself up, his entire upper body wrapped in the same green flames from before, consuming everything except for a necklace, it was made of braided obsidian chains, forming a thick rope of metal around the burning man's neck. Hanging from the chain was a pendant, a six pointed star held together by metal tentacles and a single eye floating in the middle of it, the eye darted around dazed for a moment before focusing on the Doctor.

"That necklace is something from outside our reality, it causes minor bends into the world it resides, the longer it stays into our plane of existence the stronger are its effects on reality. But it seem incapable of affecting living beings or you'd be an actual spider by now." Strange mused before flying over to confront the creature Quentin had become. "Stay here, we don't know the full effects of that necklace yet and you have very little protection against the more magical side of the universe."

"Stay put.. right" Leaning back against the nearest building Peter was glad to have such a frail mask for the first time in his life as it had ripped around his mouth allowing him to breath a little easier. "It's not like I want to jump into magical green fire, I swear." Letting his head rest on the cold and moist brick of the wall he was leaning on, he watched Strange stomp the strange green fire right out of Mysterio.

Seeing the sorcerer fight was a strange experience for Peter, the man was surgically precise, every spell was used in a cold and brutally effective manner. The absolute opposite of Spider-Man's own fighting style which even after two years of practice and training with Captain "I'll kick your goddamn teeth in and you'll thank me for it" America, was still hectic and based more on speed and confusing his enemies. Not that Peter couldn't just outpunch most of his villains, which he totally could, except maybe for Rhino and Sandman if he had enough sand to push around. It was more because most of his opponents were just normal people in juiced up costumes. If he decided to throw all his strength into it, he'd punch someone's head off.

Mysterio could clearly take it now though. Strange, was putting the guy through the ringer, anything the illusionist managed to bring up was brutally put down with barely a glance from his superior opponent. More so considering the possessed illusionist seemed to be going berserk under his shiny new fire coat.

After a few minutes watching Mysterio get ragdolled, Peter decided he had enough of a breather for the moment, standing up and jumping in place a few times to loosen his muscles up he dashed back into the fray. Before he could do anything though he noticed that the Doctor seemed to be finishing up, ripping the necklace from the mad magician before tossing the man aside. "So Doc, what's the veredict?" Spider-Man asked landing from a swing.

"This creature is a universal parasite, it uses a resident of the universe it's currently settled in to drain entire planes of existence. That's where it's powers come from, but it just got into our universe very recently, which explains why it's so… weak." Strange held the necklace up, nasty little thing that it was, and the eye in the middle of glared at them, probably trying to kill them on concentrated rage eye lasers.

"What ya doing with it then?" Poking the eye made it scrunch up for a second before glaring with renewed vigor at the spider hero. Grinning under his mask Peter turned to Stephen. "Can I keep it on a glass jar? I'll name him Stev-eye and feed him sugar cubes covered in pepper sauce."

"Sorry Spider-Man, you cannot keep the interdimensional demon necklace as your pet." The wizard smiled at his young companion's humor. "I'll be banishing it now to avoid anyone else being corrupted, slipping it in between dimensions should keep the demon inside from reaching out anyone before it starves."

Okay… kinda brutal…

Peter looked at the unconscious form of Mysterio, burns covered the man's upper body, bad enough to show bone in some places. Apparently that little fire coat wasn't just cosmetic.

Yeah, screw this thing.

"I'm cool with that. Are you taking it back to your lair then? Do some ritual manbo jambo to give it the boot?" Taking a step back to adjust his mask, he looked at the doctor who seemed pensive. "I shouldn't have to, if I'm just throwing it out of our reality there isn't a need for a grand ritual, considering how weak the demon is I should probably just get rid of it right now." Stretching out his free hand, Strange's finger curled and twisted in patterns that shouldn't have been possible for a normal human hand to do as a small black dot sprouted into existence in front of him before expanding to what seemed to be a door. Satisfied with the results of that spell, the wizard's free hand placed itself open palmed below the possessed jewelry, mumbling another incantation, red chains darted from his hands, twisting themselves into the braids of metal.

"This should be enough, now to get rid of it." Approaching the dark portal, Strange reached out, ready to drop the cursed thing into the abyss.

R̵̛̲̺̗̫̱͋ͩ͡ͅŲ̓ͯͫ̎ͫ҉͖͕̰̲̝̞N͕͇̥̪̝ͣͣͯ̌͛͂ͨ́͘

Instincts took over, time seemed to slow down as the arachnid leaped forward, a line of webbing shooting out and grabbing the doctor by the back of his cape, pulling the man back as the necklace fell through, the eye at its center rolling back in a distorted sense of bliss, tendrils of darkness sprung from the inky black of the rift milliseconds after Peter pulled the doctor back and shot forward stabbing into the teen hero after they missed the intended target. Hooking themselves into his flesh the tendrils jerked back, pulling him into the portal just as fast as they came out.

"Peter!" Dropping all sense of professionalism, the wizard blitzed forward, folding space so it would not stand in his way.

He would not make it.

Hundreds of thousands of spells rushed through the Sorcerer Supreme's mind.

None of them would help

Except maybe….

Shouting in a dead language, lost to the records of any mortal creature, ball of light flashed from his hands, streaking down the abyss, illuminating the horrors that lurked beyond, drawing their attention. A pale yellow light filled the space in between realities before the creature reached with something embracing the small light, the cursed artifact and the young hero who should not have been dragged into this. Through his haze of pain, Peter Parker screeched in fear at things his mind could not grasp.

The creature squeezed.

And then they were no more.

"So…" Detective Morrison began, shuffling against the wall to not rest on his wings. "You're really going to Japan?" The officer was curious after all, the greatest hero in the planet was leaving his home country to go teach kids in japan of all places.

"Ha! Yeah, these old bones of mine just can't throw a right hook the same way anymore, might as well teach the next generation!" A raspy voice answered. The owner of said voice could better be described as a skeleton than a man, his neck a little too long, face too thin, blonde hair that fell flat around his head and if one could look under his shirt, they'd see the spiraling red mark that seemed to shine in an angry glow at the man's side.

"Or you could just retire, if anyone's earned it it's you." Morrison offered.

"And that just sounds boring."

"Maybe because you've become addicte-" The duo stopped bantering as the sky over the city turned an black like oil, a crushing sense of fear radiating from it. The darkness then seemed to compress to a single point, barely the size of a door and a figure fell from it.

"What in the.." Turning to his companion the detective barely had time to see the man at his side explode into smoke as he leapt to the figure falling from the sky, if it was hostile it would be punched back into the atmosphere, if not then whoever it was would probably appreciate the catch.

In the air, the blonde powerhouse quickly covered the distance to the figure that was rapidly revealing itself to be a young man, in red and blue spandex ripped all over with clear signs of battle. Catching the teen in his arms, as he began to fall, the hero noticed a few more details, the spider emblem, and on the more torn side of the young hero's mask one brown eye could be seen, wide with fear, shooting every single direction as if looking for something, perhaps whatever or whoever had left him in such a state.

"Do not worry young man! For I Am Here!" All Might flashed Peter with a smile as he passed out. Memories of his fall already being locked away.

Somethings were better forgotten afterall.

It was a pleasant night for a walk in the docs, Japan's winter had just left and so the nights still had a chilly air to them. Perfect for young girls such as her to admire the ocean. Humming lightly to the sound of violins the girls twirled and danced, the shadows around her seeming to bend and sway with her as she stretched her quirk, small fledglings sprung from the shadow of her skirt and jumped around her, quietly following her lead before melding back with the darkness she provided.

Her shadows lurched for a second, dissolving the illusion she had placed over them before growing darker than anything she had seen before. In front of her a black dot seemed to drip into reality, shaping itself like a five pointed star held together by small, metallic tentacles. In the middle of the star, a red eye opened, blinked, and settled it's gaze on her.

"T̈́̒ͪͭͨ̑̋̏́͏̶̹̗̰̻͇a̶̫̤̹͓ͫ̆̒́k̜̻̦̰͓̻͈̋̀͊̇͋̀ͣe̡̲͉̭͈͒̂͐̊͋͌͛̀ ͈̩̘̙͎̝̻̱̋̐͆m̻ͣ̑̂̅̎͗́̚ͅę̲̫͈̣͉̦͎̭̅ͣ̃͊̓͗"

"... Alright! A magic thingy!" The young girl's eyes glazed over before she grabbed the necklace, yanking it into reality before putting it on her neck, noticing how warm the metal was. Shrugging she went on her way, still humming her songs as if nothing had happened.

She did not notice the metal twisting itself on her flesh. Nor did she noticed her little shadows screech in silence, twisting onto themselves, becoming more solid and scrambling under her clothes to hide from the light, leaving bloody marks on their way up.

It was a good night for a walk.

A/N: Hello fellows and felletes! I won't say this is my first romp on the whole ordeal that is writing fanfiction but the first one doesn't count because it's absolute garbage, I've deleted it and no one should ever lay eyes on it ever again…. I also have to change my BIO, do NOT let your 12 year old self do the things I did, it's not worth it, the horror man… the horror.

But yeah! This is my take on a MHA/Spider-Man crossover, it literally popped up in my brain a couple weeks back and now I have most of the story planned out, just need to write it! Which is a whole other thing…. So I don't promise consistent uploads because real life is a thing, and we all know by now that thing is not easily pleased, it demands sacrifices, and so, I must obey. Now you guys sit tight while I offer a few bags of doritos to the Lords of Free Time, they love the stuff.

Alright, see ya!
