He was back in class (specifically English which was taught by Present Mic) when he got approached by the vice president of the class. Her glare was lessened than normal as she said, "Thank you for saving me and my friends, Midoriya."
Izuku's eyes widened in surprise. "Uh, it's no big deal," he downplayed his actions, rubbing the back of his neck.
She shook her head, "You didn't need to save me, Ashido, or Jirou, but especially me. I've been cruel to you this entire time, yet you still found it within your heart to save me. So I thank you," she explained herself, bowing deeply to him before walking away, leaving him quite befuddled, almost making him late to his next class.
"…and that's why the Sports Festival is happening soon," Aizawa-sensei finished explaining, in her mummified state, bandages covering her face. She looked over the class and saw one of her students raising their hand. "Yes, Midoriya?"
"Sensei, I believe I can help heal you, if you give me permission to go to my lab and get the device," he said vaguely.
"Hmm. Sure, why not?" she allowed, watching as her student tapped on his NTC and got his portal gun. It still amazed her that he was so smart, not that she'd tell him that. She, and the rest of the students, watched with interest as he left through a portal, and a minute or two later came back holding a fire hose nozzle that had a gun handle on the bottom. It was accented with green colored tape and looked quite simple.
"Hold still," he lightly commanded as he shot a green ray of energy at his teacher. She felt herself become lighter, more lively, and in less pain than before. He fired the gun for a solid thirty seconds, and she even felt her continuous eye soreness disappear. "Okay, I'm done. I should really hand this over to Recovery Girl, it would probably reduce her workload," he mumbled to himself. "Maybe after I make a copy of it?"
"Midoriya, thank you for healing me, but you've gotta get a handle on your muttering. You could leak vital data by doing that," she warned, taking off the bandages covering her face before taking out her smartphone and activating her camera app, seeing that she was fully healed from the damages she suffered at the USJ. "Your device did a good job, but make sure it doesn't end up in the wrong hands. If villains got ahold of that…" she trailed off, letting the man make his own implications.
"I understand, miss. I'll keep it safe," he promised before the bell went off. "Well, I'm going to head on over to Recovery Girl, Aizawa-sensei."
"You do that. I, surprisingly, don't feel the urge to sleep," Shoka revealed, leaving the room to the teacher's lounge.
"Midoriya!" Tomoyo stopped her classmate, making him turn around to face her. "I heard from the others that you were heroic while I left to get the teachers. Thank you for protecting my friends!" she thanked, giving him a perfect 90° bow.
"It was no problem, I just did what anyone should do," he waved off, departing swiftly to the nurse's office. He wandered the halls, making turns and the like until he ended up at his location. He opened the door, seeing she was tending to a blond-haired student on a gurney. "Recovery Girl, I've got something for you."
"One second, dearie, I'm fixing up a patient," she told him, about to kiss the student to use her quirk.
"Let me," he said as he fired the healing gun at the student, getting rid of the bruises on her instantaneously.
"Oh my! How'd you do that?!" Shuzenji asked, gobsmacked as she examined the young lady. She looked perfectly healthy, with nary a scratch on her.
"With my Medi Gun," he explained, handing over the tool to the old woman, who examined it in great detail.
"It's just a fire hose nozzle," she said.
"But with my technological prowess I managed to make it a strong healing device. Hell, I should probably incorporate that into my Mark LXXXV," he muttered the last part.
"Young Yaoyorozu was wrong, you're a certified genius," Chiyo nodded her head, setting the Medi Gun down on a nearby desk to look over in detail later. "What about that medical spray you used on Thirteen?"
"Oh, right," he remembered and shot open a portal to his Secret Lab. "Give me a moment," he requested as he went through it, searching his desks for the medical spray in question and the recipe for it. He finally found it under the prototype forcefield generator that he was going to add to his Iron Man suit, taking both items with him back through the portal. "Here you go," he said, handing it over to her eager hands.
"Thank you, Young Midoriya. I'll make good use of this."
"Just don't leak it to the highest bidder, please. It's proprietary tech," he warned, thankful he patented it the other day, along with most of his inventions.
"I won't, dearie. Now, you have to get home, don't you? It is the end of the day, correct?"
He left the room, leaving Recovery Girl and the mystery student behind.
"Miss Recovery Girl," the blond student finally spoke up, "who was that? What is a man doing at U.A.?"
"He's a student here," she answered simply. "That's all I can tell you, dearie. The rest you'll have to find out yourself, Young Monoma."
Monoma sat up from the gurney, stretching her limbs as she thought, "I should visit and intimidate class 1-A soon. Hell, maybe that man will be there."
Midoriya was listening to some music as he finished adding the nanotech-based forcefield generator to his Iron Man armor, having added the Medi Gun to the suit beforehand.
His science bro was working alongside him, at her own desk that he made just for her. The two of them were in his Secret Lab, and after introducing his friend Hatsume to it she was ecstatic that he had a literal whole universe to himself to make babies. After showing her around and showing her to his main workshop, Mei requested to bring in her baby from the Support Department. He easily shot a portal that was outside the place, still tinkering on the power output of the forcefield generator.
Hatsume came back holding a pair of large hoverboots, humming to herself as she placed it down on her workstation. She then proceeded to grab the active soldering iron and began the process of fixing up the half-finished invention. "I wish I could use your flying tech, Greenie."
"You mean my repulsors?" he asked, not taking his eye off his own baby. He finally managed to fix the power output and held the nanotech-based invention close to his NTC, it melting back into pure nanomachines and entering its container.
"Yeah, that! All your babies could fix the problems in mine, especially for the Sports Festival," she revealed. "I'm still surprised you haven't made shrinking tech yet."
"Oh I have, I just never got around to showing you."
"What?! Greenie, you better show me it right now or else—"
Her threat was cut off when a red hexagon-shaped portal opened up near them, it distorting and messing with spacetime/reality. Inside the portal was more hexagons, with the outside having items and various unfinished inventions floating off the ground, occasionally glitching like a video game character. Midoriya double-tapped his NTC to don his Iron Man armor, unsure of what the hell was happening. His armor formed around him near instantaneously, making him sigh in slight relief for one small mercy.
"Hatsume, get behind me," he ordered, thankfully she listened and made her way over to him, him holding up one hand to the portal for offence while generating a forcefield with his other hand.
Out of the red hexagon-shaped portal came a tall, well-built man wearing a dark blue, almost black, Spider-Man 2099 suit, his face obscured by the mask. He fiddled with his wristwatch on his left arm, seemingly banishing the red portal behind him. "Are you Izuku Midoriya?" he asked in English.
Midoriya turned on his translation device, "Who wants to know?" he deflected, mentally setting his repulsor blast to the highest stun possible.
The stranger took off his mask, showing his Irish and Mexican descent. His face was set in a frown and he looked deadly-serious. "My name is Miguel O'Hara, and you have a lot of explaining to do, but first: Why the hell do you have Iron Man's armor?"
Midoriya retracted his helmet, showing his face to Miguel and his science bro. He shot a portal out of his suit's repulsor area, a green fluidic oval-shaped portal appearing. He gestured to it while keeping his forcefield at the Spider-Man of 2099. "Hatsume, get on out of here, things could get dicey."
"What is he saying?" Mei asked, looking worried and slightly irate at not being able to work on her baby.
"Nothing good, just get out of here," he repeated.
"But what about you?!" she asked, looking between the two.
"I'll be fine, Hatsume. It's me, remember?" he flashed her a fake confident smile, internally quite wary of the other superhero and why he was here. Mei looked hesitant before she went through the portal, leaving the two men alone.
"I'll ask again: Why do you have Iron Man's armor?" Miguel asked, standing tall and proud.
"I made it," Midoriya answered. "Why are you here, Miguel O'Hara?"
"You've been causing anomalies throughout the multiverse, specifically Earth-120703963."
"And that's bad because…?"
"It destabilizes the universe and if enough of them occur, it can cause the universe to implode and destroy itself," Miguel explained. "When you gave Doctor Strange that helmet it allowed him to win the fight against Thanos almost single-handedly on Titan."
"Isn't that a good thing?"
"It is most assuredly not!" O'Hara shouted, stomping close to him to get up in Midoriya's face, pushing aside the forcefield. "That wasn't supposed to happen. They were supposed to Blip and fade away for five years, but thanks to your meddling that didn't happen. Now that universe is slowly destroying itself, and it's all your fault!" he spat in Izuku's face.
"I'm sure I can fix it, I am the smartest man in the multiverse after all," Midoriya tried to offer.
"Oh, great. You're also arrogant and oh so humble," Miguel said the last part sarcastically. "What the hell can you do that I haven't?"
Midoriya dropped his forcefield and stalked over to his workbench, looking through the drawers until he found it, a small piece of Crystallized Xanthenite. "Have you tried using time crystals?"
"Time what?"
"It's also called Crystallized Xanthenite, it's capable of interacting with the flow of time and bypassing split timelines. It also can mend fractures in dimensions as well. Let me try to fix it, Miguel. It is my fault, afterall."
"Midoriya, I'd say it'd be good to see you but I hear that this is your fault, at least that's what Miguel told me," Doctor Strangefate greeted, his voice layered as he watched as Izuku and Miguel came out of the red hexagon-shaped portal. "You might be wondering why I'm still wearing the Helmet of Fate, correct?" Midoriya nodded, still clad in his Iron Man suit. The three of them were in New York City, inside the Sanctum Sanctorum in Doctor Strange's study. Doctor Strangefate was looking out the circular window as he explained, "When Thanos and his followers came for the Time Stone I quickly created an Interdimensional Portal back to Sanctum Sanctorum, getting the helmet in a hurry. I put it on for the extra power boost, and it sure came in handy."
"That was exactly the problem," Miguel spoke up, making a "tch" noise in frustration.
"As I was saying, it simply made too much sense with trying to fix your problem by using the helmet, as it gives me more magical prowess," Doctor Strangefate explained before gesturing to them outside, seeing that the world was…bleeding black was the best words.
Cars, buildings, the few people milling about, all had a black bleeding effect on them that trailed upwards to the sky, missing parts of themselves. "Oh crap."
"Still think you can save this world?" Miguel mocked, sighing in defeat as he crossed his arms. "This is what you did, Izuku, this is your fault. If you hadn't meddled and created anomalies then this world would still exist to see tomorrow."
Midoriya bunched up his hands, making fists as he thought fervently on how to solve the issue. How the hell was he going to fix this? Why the hell was the Marvel universe so against change? Unlike other universes which was pliable, Marvel universes were tough, not able to change much without breaking.
How could he fix this?
How?
How how how how how how how how—
Wait, his time crystal. He brought it out of his pocket, looking at the purple gem closely as he thought of the possibilities. "I'm an idiot. The solution is so obvious," he said as he opened a portal to his Secret Lab. "Guys, give me some time. I'll be back," he said before he disappeared through his portal, leaving the two heroes alone. The two of them went outside to the front of the building, seeing that everything was bleeding black.
"I have faith that Midoriya can solve our issues," Doctor Strangefate said as he made a motion with his hand, healing the damage of the anomalies easily in front of him temporarily, like putting a small bandaid on a large bullet wound. While it was easy to fix it temporarily, fixing it permanent was a lot harder.
"Please," Miguel dismissively said. "I doubt that he can do anything to stop it."
"Do remember that he managed to make portal technology that can cross throughout the multiverse," the sorcerer reminded, keeping quiet about Desiree's meddling. "Much like yourself, Miguel."
"As if that was original. The kid's a fraud, I'm sure of it. I mean, he has Tony Stark's armor and Rick Sanchez's portal gun? He's unoriginal at best, and a thief at worst."
"He has done a lot of good," the doctor tried to defend the kid.
"And look what it did to your world," Miguel gestured to the world in front of them. "By tomorrow you'll all be dead," he said bluntly, sighing again for the upteenth time. "I still wonder why it was a pain in the ass to get to his reality."
"Hmm?"
"Traveling to other universes is usually medium-difficulty. Imagine it like this: Going to another universe is like swimming in the ocean, as long as you know how to move it's a little easy. But going to his is like leaving the planet for another ocean, as if it's a whole other set of laws and rules."
"He once said this was a 'Marvel' universe, if that makes any sense," Doctor Strangefate helpfully supplied.
"It doesn't, but I'll look into it," O'Hara promised.
"I'm back, it's-it's—BELCH!—done!" Midoriya burped loudly as he came stumbling out of a green portal from the second floor, holding a small baton that had a small purple crystal at the top. It looked futuristic, having buttons and a keypad on the sides. He came tumbling and racing down the stairs once he realized they weren't with them, joining them outside. "It wasn't that hard to make after—BURP!—after I thought it up," he belched out. "Sorry, I had a lot of soda," he apologized. "You guys have the Avengers Tower in this universe, right?"
"We do, why?" Doctor Strangefate answered, tilting his head, curious on why he needed the information.
"We need to do this on a tall building, it's-it's—BELCH!—very important," he said, double-tapping on his NTC to don his Iron Man suit. "Follow me, please," he asked them as he went outside and began to fly slowly to the Avengers Tower. The two of them decided to humor him as the Spider-Man of 2099 and Doctor Strangefate followed closely behind, the former web-slinging and the latter flying with his Cloak of Levitation. They saw the devastation of what the anomalies was doing to this world, various people rioting and freaking out over bleeding black. Midoriya silently apologized to what he did to the residents of this world as they got to the top of the tower. It was flat and empty, having a helicopter landing on the top. He mentally commanded his suit to shed off him as he took off his NTC, placing it on the ground and tapping a pattern onto it. It suddenly released all the nanomachines it had and built a tall tower that had a receptacle for the baton. He plugged it in and tapped a few things on the keypad before activating the device. The tower began to shake and rumble as a purple energy pulsed out of the top, covering the Earth and all of the universe from its standing point. Miguel and Doctor Strangefate looked off the tower and down on the street below, watching in awe as the black bleeding stopped, the world returning to normal. "Great, it worked!"
"How?!" Miguel demanded, "How the hell did you fix something in a half hour that I've been trying to fix for years?!"
"I did say I was the smartest man in the multiverse, didn't I?" Midoriya sassed out, taking out the time crystal baton and taking back the NTC, dismantling the thin tower, putting the device back on his sternum.
"You did this on purpose!" the Spider-Man of 2099 accused, pointing at him.
"Midoriya would never do this on purpose," the sorcerer defended as he took off the Helmet of Fate, seeing that Doctor Strangefate was no longer needed. He immediately turned back into the "normal" Doctor Strange, him sighing in relief as he did so. He held the helmet underneath his arm as he continued, "He's a good kid with a great mind on him," Stephen then looked on over to the young man, "Knew you could do it, Midoriya."
"Thanks, Doc. Good to see your face again."
"I'd have to agree, it's a little stuffy underneath this thing," he gestured to the Helmet of Fate.
"Can we get back on topic?! How the hell did you do it?!" Miguel shouted, wanting to grab the technology for himself to fix the worlds that needed help.
"Well, I noticed that all the Mar—I mean, all your universes were stagnant and unwilling to change, so I changed the rules for this reality. I could change all the realities to make them all anomaly-willing but—"
"You can?! Then why didn't you do so?! It'd make my job so much easier!" the futuristic Spider-Man interrupted, stalking on over to the young teen to get what he wanted—no, needed. He could probably figure out how the nanotech worked, given enough time of course, he just needed it first.
A wall of orange magic stopped him from getting even closer, Doctor Strange raising an eyebrow at Miguel's actions. "Don't get any closer," Stephen warned. "While I may not be happy that Midoriya caused all this, he did save the day, something that even you couldn't do," he shot the barb, seeing Miguel wince dramatically. "Midoriya, as much as you may feel your nerves grating from this version of Spider-Man, please help him fix the universes."
Izuku considered his next actions before sighing and saying, "Okay, I'm going to need a large power source, and the reality number of your original universe."
Much later, on Earth-928B
Midoriya was hard at work, attaching the thirty pound Crystalized Xanthenite to the top of the large tower. He, Miguel O'Hara, and a large plethora of Spider-Men and women had helped him build The Interdimensional Tower, as they have dubbed it. It was powerful enough to radiate its energy throughout all (Marvel) universes, changing them for the better and allowing anomalies to occur and not destroy the universe in question.
"Okay, everyone, this has been a wild three days, thank you for all your help. Now, Miguel, will you do the honors?" Izuku asked tiredly, having been awake for a solid 63 hours. He gestured to the comically-large switch on The Dimensional Tower, wanting his associate to do it. Miguel looked equally tired, hiding his giddiness and nervousness as he pulled the switch, the room vibrating from the energy building up within the tower. It finally released, a pulse of purple energy radiating from it, surrounding the Earth and all the (Marvel) universes, in time, of course.
"Yay…we did it," the green-haired inventor yawned out, pulling out a flask to down its contents, only to find out that it was empty, much to his dismay. "Okay, keep that tower on for the next six months or so, then it'd be safe to turn off. I'm going to sleep for the next…year or so," he guessed. "Miguel, before I leave, can I take a look at your portal tech?"
"Sure, just don't break it. And it's called a dimensional travel watch," the Mexican informed him, handing over his watch. The two of them had mutual respect for each other now, seeing as they worked together for a solid three days straight. "How come you're not glitching, by the way?"
"I made it so that my portals leave a protective film over the user when they walk through it, protecting them from glitching," Midoriya explained, scanning the dimensional travel watch with his JARVIS sunglasses. "From my preliminary scans, your dimensional travel watch is quite limited when compared to my portal gun. I mean, it can barely even get you out of the Marvel universe! I could fix it…could being a strong word," Izuku thought aloud, nodding his head sometimes before handing back the watch to O'Hara. "Nah, I won't, don't want you discovering the truth."
"The truth? What truth?" the Spider-Man of 2099 asked, confused. "And what do you mean by 'the Marvel universe?' Doctor Strange mentioned you said it once earlier a couple days ago."
"Ah, ignore what I said. I should probably get going anyways," Midoriya said absentmindedly, holding out a hand for Miguel to shake. There was once a second of hesitation before the two shook, Miguel having a genuine smile on his face.
"I know I was harsh on you, but you're welcomed back anytime," O'Hara told him, watching as the young lad opened a portal with his portal gun.
"Thanks, Miguel. See you when I'll see you," he farewelled, leaving the portal soon after. He emerged on the other side in his room, landing face first on his pillow, wondering where Desiree was.
He rested for a solid three minutes before he realized that he was radio-silent to his mother, Desiree, and his school for the past three days while trying to fix the Marvel universes.
He was so in trouble.
"Fuck."
