"Mr. Midoriya, did you get taller?" Nozomi asked again as the young man entered the nurse's room through a green portal, carrying a green handheld cooler. It was after school hours and he, Nozomi, Recovery Girl, and Yagi were all in the room, with Toshiko laying down on a resting bed wearing extremely baggy civilian clothing.

"Like I've told you, yes, I modified my genome to make myself more combat-ready," the greenette told the chimera. "I'll tell you all about it later, I promise."

"Is that it?" Recovery Girl asked the greenette as he pulled the neon orange syringe out of a specialized cooler.

"Yes, it is," Midoriya answered before asking, "Do you want to do it or should I?"

"I'd like to do it, dearie. No offense to you but I believe you don't have much practical medical knowledge," Chiyo said, gently taking the syringe and examining it in detail. "So how does it work?"

"Well, the drug is a form of CRISPR, highly modified and taken to an extreme to help immediately once injected," Izuku explained. "However, this version of Extremis is very watered-down, only healing the individual once while giving none of the super soldier abilities."

"Can we do it already?" Yagi asked. "I'd like to eat an American hamburger again, if you all don't mind."

Recovery Girl looked to Nozomi, who nodded to her, as she inserted the syringe into the skinny left forearm of Toshiko. She pumped Yagi full of the modified Extremis and they all waited for something to happen.

And boy, did something happen.

All over, Yagi's body glowed a bright orange, nearly blinding everyone (sans Midoriya with his JARVIS sunglasses) as she was engulfed in the light show. Midoriya watched with smugness and fascination at how Toshiko's normally rail-thin body got buffer as when she was in his prime as All Might. Her legs, arms, her torso, and her head glowed orange as they expanded rapidly, the skin, muscle, and cartilage, and bone knitting together as it pushed outwards. After thirty seconds the light show ended, revealing All Might in all her prime glory.

The first thing All Might did was take a deep breath, a smile crossing her features as she exhaled. "My boy, you did it, you truly healed me when no other could!" she boomed out, the baggy clothing she was wearing now tight across the body.

"My god, dearie. This can change the world!" Shuzenji cooed in delight. "Did it hurt at all, Toshiko?"

"It felt like I was getting pulled apart, but it oddly didn't hurt that much!" All Might answered loudly, relishing the ability to take a deep breath and maintain it. She then heard something she hadn't heard in the last five or so years: Her stomach growling. All Might teared up at hearing the noise, getting handed a tissue by Chiyo, who was smiling. "I need to go and get a burger!" the blond informed them, racing to the door, ignoring the cries of protest from her personal doctor. "Sorry, but I really want a bacon cheeseburger!" she farewelled as she shut the door behind herself, the door rattling on its hinges.

"Well that was something," Nozomi commented, a smile also on her face. "Young man, you have restored the symbol of peace, is there anything you want?"

"Hmm, can I take a rain check?"

"Of course, Mr. Midoriya! Now, you said you'd explain your new body later, did you not?" Nozomi reminded the young man.

Midoriya sat down on a nearby chair as he explained himself, "I used Extremis to super-enhance my body, making me taller, stronger, faster, that sort of thing. It also gave me exothermic abilities, such as heating up parts of my body and allowing me to breathe fire."

"My goodness, dearie! You did have supervision before doing it, right?" Recovery Girl asked hastily. "I mean, you wouldn't do such a moronic thing, would you?"

Izuku chuckled nervously before saying, "I mean, I did have someone watching, but they've never gone to school. Like, at all."

Silence permeated the room, both Nozomi and Chiyo shaking their head.

"Mr. Midoriya, don't alter your genome, other people's genome, or do something of that caliber again without supervision by me, Aizawa, or Recovery Girl," the principal practically ordered, a disgruntled look on her face.

"Um, aye aye, madam," Midoriya agreed, not wanting to disappoint them again. "I get the message, Miss Nozomi. Can I go now?"

"Nuh uh," Recovery Girl interjected, taking out her stethoscope and pressing it against his well-built chest, hearing a steady and strong heartbeat. "I couldn't get Toshi to do it, but I'm certainly not going to let you go a second longer without getting vetted by me," Shuzenji promised, seemingly satisfied by the results. She retracted her medical tool before going around and getting an otoscope, checking his ears with them. After that she measured his temperature, looking surprised by the result. "You have a fever and yet you don't present any symptoms?"

"Oh, that? A by-product of Extremis is that the user's average temperature raises by a little."

"A little?" the doctor repeated unbelievingly. "You have a temperature of 105°! That's well above the temperature of a fever!"

"Do you feel off at all, Mr. Midoriya?" Nozomi asked from the sidelines.

"No."

"Then he's probably fine, though have fun doing examinations on the man, Chiyo."

It was the longest hour or two of Midoriya's life, getting examined all the while in old and new ways. It was time that was better spent on invention making, and Midoriya zoned out as he thought about inventions.

A gravity trap?

Electric boxing gloves?

A pair of mechanized wings like the Vulture?

So many inventions, no time to make them.

After Recovery Girl was done, Izuku was free as a bird, where he then went home to make love to Desiree.


"Sweetie, can I come in?" Midoriya Inko asked as she knocked on her son's door. After hearing a yes from him she pushed open the door. "I baked some butter cookies, do you want some?" Inko asked as she carried the plate of said cookies.

The younger Midoriya stopped on his project and eagerly took a cookie and munched on it. It was fresher and better than the ones you could buy at the supermarket, at least in his opinion. "Thanks, Mom!"

"Of course, sweetie. Anything for my darling little boy."

"Mom!" he protested, his cheeks reddening at her affectionate terms.

She giggled lightly before looking at what her son was working on, which appeared to be a red-skinned adult male. "What is that?" she questioned.

"That's JARVIS," he answered, taking another cookie and getting back to work on screwing in some screws. "He's going to be here helping around the house. He can make a wide variety of dinners, is self-learning, and a good companion for day to day existence."

"Isn't this 'Jarvis' your AI thingie?" Inko inquired with a tilt of her head, setting the plate aside on the TV in the room. The cable box was mysteriously tampered with, having a purple crystal poking out of it.

"Yes, JARVIS is my creation but don't worry, he doesn't mind taking care of the house and making your workload lighter," he assured her. "You wanna see him activate, Mom?"

"Sure, sweetie."

After a couple more minutes of silence, only broken by the young inventor screwing in screws until finally he finished. He clicked the "On" button that was hidden at the base of JARVIS's neck, and the eyes on the synth slowly blinked open. "JARVIS, buddy. You there?" Izuku asked.

"Yes, Sir," the synthetic human answered, looking much more alert than before. JARVIS sat up, taking the room in with wonder as he patted himself down. "I have a body now, Sir. I can feel and sense things."

"Yeah you can, J," Izuku said with gleeful undertones. "Try standing up," he suggested as he got off the bed, waiting for his AI to do the same.

It took JARVIS a second but he manipulated his legs and hands to get up, standing on wobbly legs before he corrected himself quickly. "This is amazing, Sir. I'm getting terabytes of information just by standing!"

"Isn't terabytes a lot?" his mother asked, offering a butter cookie to the android who declined nicely.

"It was in the 21st century, but things have advanced enough where installing a thousand petabytes was easy enough with some tinkering."

Inko sighed happily, not able to keep up with her genius of a son. "That's nice, dear."


"Master, what universe are you going to now?" Desiree asked him as he suited up in an instant, his Iron Man suit coming on him like a second skin and faster than ever. He kept the helmet off, however, wanting to be seen as a human instead of a synth. He popped in his translation earbuds and set it to English, adjusting them so they fit snugly.

"I'm going to the Fallout universe, or at least a variation of one. Before you ask, I'm going to get a device from said universe to augment my Iron Man suit. I could make the device myself but I'm feeling lazy," Midoriya explained before raising an arm and shooting out a green fluidic portal to the universe in question. The two of them went through, arriving in Freeside, New Vegas. The sun was high above them, it being hot and very dry. The buildings around them were dilapidated and mostly vacant, as they should be after a nuclear war ravaged the main countries of the world.

The homeless and the vagrants around him jumped at seeing such technology, giving him and his invisible companion a wide berth like the people of New York. Midoriya and company walked confidently through Freeside, going past the Old Mormon Fort. Along the way they heard two separate criers:

"Come to Mick and Ralph's for all your shopping needs! We have stuff we're not even allowed to sell, people; only at Mick and Ralph's!"

"Hungry? Thirsty? Horny? The Atomic Wrangler has you covered!"

If Midoriya was a drinker, and he wasn't (it tasted foul compared to soda), he might've been tempted to go to The Atomic Wrangler, but he had none of the money of this world to gamble with, so he kept on keeping on.

"What happened to this world, master?" Desiree asked, checking out the clothing of the female crier. "It's like they got…" she trailed off, hoping her master would understand the lack of words.

"Like they got bombed back to the stone age? They certainly did get bombed, and if this universe follows the rules, then they got bombed on October 23rd, 2077, approximately 200 years ago in this universe," Midoriya answered. "If I was feeling more altruistic then maybe I could help this world, but that's not the mission at the moment."

They passed The King's place before coming to a stop at The Strip North Gate. It was armed with securitrons, some at elevated positions, all guarding a red fenced door. There was a neon sign that read "Welcome To the Strip" that was currently flashing on and off, trying to attract attention. Midoriya watched as someone attempted to bypass the security and made a beeline to the door that entered The Strip.

Tried, mind you.

He got shot upon by the security personnel until he ragdolled against the floor, dead.

"Just like the games, Izuku, just like the games," Midoriya reminded himself as he walked close enough to where the securitron force stopped him. All of them had screens where there was a cartoon face of a security guard.

"Submit to a credit check or present your passport before proceeding to the gate. Trespassers will be shot," the robot informed him.

"1C 3C R34 M," Midoriya nervously told the guard, hoping that he could pass the 80 Science check.

Suddenly the screen of the securitron flickered on and off before stabilizing, various clicking noises happening within its chassis. "Uh…thank you, sir. You may proceed," it finally said as it moved out of the way for the greenette.

"Fuck yes!" he whisper-shouted, walking casually into New Vegas proper. The place was filled with drunk people, strippers, and neon lights.

A pale comparison to the illustrious Las Vegas in Midoriya's universe, especially the 21st era version, but it had its quirks. Gomorrah, the Lucky 38, things he saw behind a computer screen were now real and smelled/looked real (as it was real).

"This is so cool! But time to do what I need to," Midoriya said as he walked up the stairs to the Lucky 38 before being stopped by another securitron.

"Halt! Mr. House is not accepting any visitors at this time!" the robot denied, holding up its claw hand to stop him.

"Desiree, I wish time was stopped."

One snap later and time froze.

"Thank you, my dear. I'll be sure to award you later," Izuku promised as he got the panel off the back of the securitron.

"Oooh, I love it when you promise me things!" Desiree squeed, obviously happy if one could observe her.

Alas, no one literally could as the young man tinkered with the inner workings of the robot. He took out some parts, put them back in, scanned some of them with his JARVIS sunglasses until he was sure of it. He put the panel back onto the robot and got into the position he was in earlier. "Desiree, I wish time was resumed."

Another snap later and time resumed.

Midoriya held out a gauntlet-clad hand and snapped his fingers while turning his hand into a finger gun, much like Kaminari when she used her quirk, pointing at the securitron. The robot's screen flashed green three separate times before saying, "What do you want, Creator?"

"Damnit, I didn't want them to address me like that, but beggars can't be choosers. Robot, take me to see Robert House, no robot escort from the others," the inventor ordered.

The three of them went inside the Lucky 38, with Midoriya reprogramming all the securitrons he could see as he was escorted to the Penthouse. All the robots, namely Jane and the other robots with names, held no power over Izuku as he situated himself in front of the large screen that was projecting Mr. House.

"I must say, I've never had anyone commandeer my securitrons so easily before. And if the recordings of my robots are correct, you did it with only a single hand, while also wearing the thinnest power armor I've ever seen. Who are you?" the man asked.

"My name is Izuku Midoriya, at least that's how you would say it in America. I come from Japan, and I want to help you, Mr. House," Izuku told the projection.

"Not without something in return, am I correct?" Mr. House asked cleverly. "You must be some unheard of tech wizard of the wasteland if you can reprogram my securitron army with just a pointer finger."

"You could say that. I know lots about you, Mr. House, such as you saved Las Vegas practically single-handedly on October 23rd, 2077, when the bombs dropped. If I'm correct, you ran out of time when it happened."

"I'm impressed, you know your history, including things that only I know of. Mr. Midoriya, what do you want? After all, you went through so much trouble just to talk to me, so what is it? Money, perhaps?"

"None of that, nothing monetary. The thing I want is something simple: A stealth boy, but two preferably," the greenette explained. "In exchange, I can help you with your Mark II OS that you've been wanting for the last 200 years.

"If my screen-self could raise an eyebrow I would. How do you know about that?" Mr. House asked cautiously, wishing he had control over his securitrons to better handle the wild card in front of him.

"Let's just say you have a mole and a rat by the name of Benny and Yes Man," Izuku answered. "But back to my offer."

"All right, Mr. Midoriya, I'll bite what you are offering. If you are able to replicate and upgrade my security systems to the Mark II OS, you just want two measly stealth boys?" Mr. House asked from his monitor, his picture ever present and never changing. "No caps, perhaps?

"My universe doesn't operate on caps, sorry."

"Are you saying that string-theory is correct and that there's infinite universes out there?" the former CEO of Robco Industries questioned. Wordlessly Midoriya created a green portal nearby him. "Fascinating, that's eye-opening. Is your universe still operating under paper money?"

"Yes, and my stealth boys?"

"Consider it done, Mr. Midoriya, as soon as you finish your end of the deal. I'll be providing you a computer and chair for you to do your work," Robert offered as he controlled a securitron to direct the young man to the kitchen in the Penthouse. He projected the video feed of himself to the robot as he continued, "Give me half an hour to get the supplies here."

"Not needed, Mr. House. I have a laptop with me already," Midoriya declined, tapping out a sequence of taps and presses on his NTC to produce a razor-thin laptop entirely composed of nanites. It was loaded with paid software to better make the software upgrade to Robert's security system, as he pre-planned this earlier.

"A laptop? Am I to presume that your universe had made a portable computer, akin to a Pip-Boy capabilities?" Mr. House asked with keen interest of the slim device that his associate conjured. The operating system was unlike anything he'd ever seen before, it having a visual-based and click it system. He watched as the young man opened up one of the softwares and cracked his knuckles before tapping very quickly on the keys.

Midoriya slowed for a second as he answered, "Yes, my universe has created razor-thin laptops, if you can believe it."

"Funnily enough I can't, Mr. Midoriya. Let's discuss an arrangement later, when you're done. Would you like any beverages?" the older man offered, only acting so nice and butler-like due to what the young inventor could possibly do.

"I'd like a Nuka Cola, never had one before," he requested, "Oh, and I relinquished my hold over all the securitrons I commandeered," he offhandedly remarked, resuming his earlier speed of typing.

"I do have to wonder what your world is like, without such a refreshing soft drink that I admired when I had a body. And thank you for that. Jane, can you please get this young man a Nuka Cola?" he asked nicely, secretly ordering her to do as he told.

"Of course, sugar. We might have one in the casino area," Jane answered as she went to the elevator, descending the floors until she retrieved the ice-cold soda, bringing it back up to the young man. "Here you go, Mr. Midoriya!"

He tilted back the drink after taking off the bottle cap, stowing it away for a keepsake later. It tasted like if Coca Cola and Pepsi had a child, it being pleasant to drink. "Th-thank you, you two—BELCH!—I'll-I'll have the soft—BURP!—ware ready for within an hour," he promised as he disgustingly burped out, getting to work as Mr. House and Jane left him be.

"Sir," JARVIS began, speaking from the sunglasses, "we have no idea how their software works nor how to upgrade it. How are you going to accomplish the impossible, Sir?" the AI asked respectfully.

"It's gonna be easy, J," Midoriya whispered to not alert the owner of the Lucky 38. "I'm not making code that upgrades the software, I'm making code that makes itself upgrade the software."

"Pardon me, Sir, but what is the difference?" JARVIS asked, not really seeing the difference.

"It's simple: I'm gonna plug in the USB drive into Mr. House's systems and it's going to root out what part of the system is missing its software/drivers to upgrade; that's where you come in, JARVIS, as you will build within less than ten seconds the code and drivers necessary to update the securitrons."

"Excellent thinking, Sir. Pure genius with a dash of cleverness," the AI sassed out before leaving his creator to his work.

An hour later, and after finishing his Nuka Cola, Midoriya had finished and transferred his nanite laptop back into his NTC. He got up, all the while holding the USB stick with the program on it, and approached the giant monitor of Mr. House, telling him, "Mr. House, I've finished what I promised. You ready to upgrade?"

"Forgive me if I don't completely trust you after what you've done to me," Robert answered. A securitron approached him with a screen of an American crash test dummy. "I've isolated this securitron from my network, plug in your USB into the slot provided to show me it works," Mr. House ordered as the robot opened up a slot for a single USB port.

With a gulp that it'd work Midoriya plugged it in, watching the robot act if nothing was amiss.

"There's no malicious code, thank you for that. And…you did it? You did it, you upgraded this securitron to the Mark II OS," he said excitedly as he commanded the crash test dummy securitron and manipulated it to unplug the USB and plug it into his main control console. The flash drive flashed red repeatedly before it turned into a solid green, indicating that the code was upgraded. "I've just uploaded and transmitted the Mark II OS to all available securitrons, thanks to you, Mr. Midoriya."

"That's good, now you can take more charge and stuff like that," the green-haired inventor congratulated.

"Here's my end of the bargain," Mr. House said as he got a robot to offer him a crate full of stealth boys, Midoriya opening a portal and sending it to his Secret Lab. "What will you be doing with them, as I'm curious."

"The armor I'm wearing could be considered power armor in your world, obviously more advanced, of course. I want to take the stealthiness of the stealth boys and integrate it into my suit, so I can go all incognito and the like." Midoriya then shot out a portal and was about to leave with Desiree when he was stopped once more by Mr. House.

"Remarkable…the technology and you! If you ever need a job, and you're willing to commute to another universe…" Robert offered, leaving the idea for the young man.

"I'll keep that in mind, Mr. House. But I must get going," Izuku insisted, leaving through the portal with Desiree. He emerged in his Secret Lab in the Workshop portion, various gadgets and doodads left out haphazardly in a sort of controlled chaos. He mentally commanded the nanomachines to get off him and back into the NTC, appreciating the cooled air that was circulating in the room.

He had work to do—

"No no! Master, you're going to eat me out!" Desiree interrupted his train of thought, turning back into a human and tugging him to the bedroom that he had established.

Izuku rolled his eyes good-naturedly as he and she got onto the bed, pulling off her soaked panties with his mouth, a huge turn-on for her. The juices were erotic tasting and gave him a raging hard-on, something he'd tend to later with Kacchan or Minori (maybe).

He trailed his tongue across her labia, teasing the clit by not touching it. He purposefully ignored it as he penetrated her with his tongue.

"Master, please play with my clit!" she begged, scooting closer for him to take the hint.

"Not yet, my dear. It's called foreplay for a reason," he reminded her, using his right index and middle finger to finger her, her eyes rolling to the back of her head in pleasure.

He knew just how to rile her up, like an expert puppeteer, as he finger-fucked her and finally sucked on her clit, nibbling it gently to give a little pain and pleasure. To push her over the edge he popped a finger in her asshole, and she proceeded to squirt all over his face, her sweet nectar covering him as she breathed in and out heavily, her eyes unfocused.

"That was…amazing!" she heaved out, sweat on features. Desiree looked to his prominent bulge and asked seductively, "Got something for me?"

"No, it's okay. This was for you—"

She interrupted him by slamming their lips together, him instinctively taking over with his tongue as he'd been trained to do. They snogged heavily for ten seconds, both of them feeling each other up. "This is about us, master. Do you want a blowjob?"

"Yes, please. Thank you!"

It made her smile to hear him say those words, even with all the power he now had, that being her sex magic and his brains. Lesser men would go mad with power, ever-aware that they held all the cards and all the control.

But not her master, the lovable ball of sunshine he was. Desiree pulled off his jeans and All Might-themed underwear, purposely getting hit in the face with his bitch breaker of a cock. It looked monstrous and powerful, with visible veins running up and down the length. The top was a reddish-purple color, a bead of precum at the top of the urethra, just begging to be scooped up before it slid down his cock and created a rudimentary lube.

The sex genie began by pumping his length with her lithe hands, unable to fully close her hand around his cock as she jerked him off. He sighed and "ooh" at the contact, relaxing at it. Desiree was unable to take it anymore and began to deepthroat earnestly in one go, knowing he liked that. Her head went down and down until it met his well-groomed pubic hair, her eyes not watering due to her being used to it.

"My god, that feels so good, dear," Midoriya encouraged, resting his hands on her head, massaging her scalp. They both enjoyed the sloppy toppy before he felt his natural release rearing its ugly head. "I'm gonna cum!" he alerted her as he pushed her down as far as it could. She didn't mind in the slightest as his tasty and sweet cum filled her throat, her gulping ten times to handle all the cum he produced. "T-thanks, Desiree."

The genie pulled her mouth off his cock as she rested against his dick, looking cock drunk all the while. "No problem, master."
