The next day

"So this thing can build any type of baby I want?" Hatsume asked, looking over every inch of the SIF. She and Midoriya were in the latter's lab at Geonosis Tech, and currently Midoriya was introducing her to one of his more impressive inventions, or babies, as she called them.

"Yep. There's even a port for a USB stick to plug in and import your blueprints," he said as he pointed to the USB hub. "FRIDAY, say hello to my friend."

"Good evening, Miss Hatsume and Boss. What would you two like to build today?" the AI asked, surprising the pink-haired inventor.

"You've got an AI inside this thing?! So cool!" she shouted.

"Yep, built her myself. Got any 'babies' in mind for the SIF, Me—I mean, Hatsume!" he slipped up, forgetting that the sex he had with Desiree where she pretended to be Hatsume didn't count to their closeness.

She graciously ignored (or didn't notice) his slipup as she asked with her trademark grin to her science bro, "Hmm, tell me: Have you ever seen the anime 'Attack on Titan?'"

"I'm familiar with it, why?" he replied, confused where she was heading.

"What if we built an Omni-Directional Mobility Gear baby?! Ooh, that'd be so much fun!" she gushed as she manipulated the hologram to set up a new blueprint/creation. Midoriya watched her fumble and mess up at navigating the holographic interface, cringing a little inside at her novice-like grace.

"Let me," he offered, her getting off the reigns and letting him take over. He did a quick calculation of Hatsume's proportions as he set up the basic geometrical shapes for the ODM. "This isn't flashy enough, want me to add a splash of color?"

"What do you have in mind, Greenie?" Mei asked, not knowing the memories (and feelings) she was stirring up inside him.

"I, uh, was thinking hot rod red and yellow," he stammered out, adding the color in to the basic shapes and showcasing it to his friend.

"I like it!" She gave her approval with a thumbs up.

"Perfect, let me keep fiddling with this," he said as he refocused on the "baby" he was making. It was coming together quite nicely until he hit a snag. "Damnit. Hatsume, we have a problem," he alerted his science bro.

"What's the problem, Greenie?" she asked, looking away from the stacks upon stacks of weird-looking metal in the corner of the lab.

"The metal we could use to build the ODM would make it too heavy, and there's no metal on this Earth that's both light enough and strong enough to use in its construction," Midoriya explained, looking slightly miffed at the thought.

"What do you mean by 'this Earth?'" the pink-haired inventor questioned, finding his word choice rather odd.

Izuku smiled as he stepped away from the SIF as he palmed his portal gun through his pocket. "Hatsume, ever heard of string theory?"

"Duh, of course I have. Why?" she asked before putting two and two together. "Wait, do you have a baby that can cross the multiverse?!" she asked excitedly, her eyes turning into huge saucers at the thought.

"Yes, I do," he said with a wide smile as he pulled out his portal gun, turning on the parental lock as he passed it over to his friend. She took it with grateful hands as she examined it in great detail. It was white in design and sleek, having a glass tube at the top of the gun filled with a weird green electricity that acted as a tesla coil. There was a red display that read "AO3-47269165" with a black dial underneath it. Mei tried to pull the trigger to see what it would do (of course), but the trigger wouldn't move. "It's not broken," he informed her, "I knew you'd try that, so I prepared in advance."

"Meanie, Greenie," she blew a raspberry with her free hand as she handed back his baby.

Midoriya rolled his eyes good-naturedly as he took back his invention. "Don't tell anyone about this invention's multiversal capabilities, Hatsume. This will change the world if they found out," he advised her.

"Got it, but who's 'they?'"

"The Hero Commission, the president, the government, anyone with power really," he elaborated as he keyed in some very specific coordinates into the portal gun. "Watch this," he said as he shot open a small portal near him. He reached in and, after wildly grabbing around, managed to pull in his Interdimensional Goggles from his room. "Ta-da!" he said as if he just pulled a rabbit out of a top hat. Hatsume clapped excitedly, wanting to see what this new baby would do. "Here, try them on. I got to build something real quick," he said as he handed over the goggles.

Mei put them on quickly and, after some verbal instructions from her science bro, turned it on and viewed the multiverse. There was a reality where she was building a baby that looked like hoverboots (which gave her an idea for later), another reality where she was working on an mechanized armor with Greenie, and so on and so forth. Frankly it was all very inspiring seeing what the other Hatsume Meis were doing.

"And done! Woo! That wasn't that hard, though it still needs a trial run," Midoriya muttered out the last part as he tapped his friend on the shoulder to jostle her out of her stupor. She took off the goggles and gave it to him, watching as Greenie went over to computer and plugged it in with a wire. The computer came to life, showing a bunch of data on-screen that was mostly incomprehensible to Hatsume.

Izuku donned the goggles as he typed in keywords into the computer, trying his best to find a reality where it had the metal he needed, which was mithril if he wasn't mistaken, as it was a lightweight but durable metal. He crossed dimension after dimension off the potential worlds he should visit before he stumbled upon it. "Okay, Hatsume, I'll be back soon. Don't make any explosions while I'm gone, 'kay?" he requested as he spun the dial to the universe he had found.

"No promises, Greenie!" the pink-haired inventor replied, planning on doing just that. He sighed in defeat as he opened a portal to the reality in question, stepping through only after he turned on the energy shield on the Energy Gauntlet.

It left Hatsume alone in the lab, allowing her to be a Nosy Nancy. She observed everything, especially the cubic piles of metal in the back corner. "JARVIS, is it?"

"It is indeed, Miss Hatsume. How can I help you today?" the AI answered, monitoring her closely.

"What's this metal called? I've been around and seen most of them, but never anything like this," she said as she knocked on it, watching as purple ripples spread from where she struck it.

JARVIS hesitated for a second before deciding his creator would divulge the information himself to her. "It's called vibranium, Miss Hatsume. It has the ability to absorb, store, and release large amounts of kinetic energy."

"Woah! That could be so useful if implemented into a baby! Maybe a shield or a suit of armor?" she hypothesized aloud, many thoughts racing inside her head at the potential of this metal.

Suddenly a green fluidic portal opened up inside the lab. A man wearing a full suit of medieval armor singed and covered in soot with a sling bag made of leather on his back came out. The man lifted up his helmet, showing emerald green eyes. "Hey, Hatsume," Midoriya said tiredly, as if he just came back from a battle. "How long was I gone?"

"About thirty minutes, Greenie, but what happened to you?" she asked, looking him up and over.

"Of fucking course. If my guess is correct, which it is, then I experienced time dilation."

"Ah. How long were you gone in our time?"

"Two days," he voiced simply before shredding off the suit of armor he acquired and placing it in an empty corner of the room. "I had to dress up to fit in with the crowd in the dimension I traveled to. I had to fight goblins, skeletons, and zombies, Hatsume. It was a bitch to do!" he lamented as he finally took off his sling bag, taking out a dark blue ore. He walked over to his SIF and placed the metal into the bin, telling the fabricator to digest it and make the ODM out of it.

"Wait time is an hour, Boss," FRIDAY told him, working on building the ODM.

"Sir," JARVIS's voice echoed throughout the room, "someone in the lobby is asking for you. She has the appearance of the woman who you invited to visit you yesterday, one miss Iida Tomoyo," he alerted his creator, pulling up the feed of the lobby and broadcasting it to the nearest monitor.

"Send her down, JARVIS," Midoriya ordered, taking a seat in a nearby chair to relax. He and Hatsume waited a minute until the elevator door opened, a dark blue-haired woman wearing glasses on the inside of the elevator. She pushed her glasses further up on her nose as she observed the lab, seeing the man in question along with a friend. "Welcome to my lab, Iida."

"How do you know my name?" Tomoyo asked.

"My buddy JARVIS scanned your face/body and scoured the Japanese database until he found a match. Wasn't really hard, considering you're from the Iida family," Izuku shrugged. "This is my science bro, Hatsume Mei."

"Good to meet you," Iida held out a hand to shake.

Hatsume shook it readily and overenthusiastically, a wide grin on her face. "Me and Greenie make lots of babies when we're together!" she revealed, causing the dark blue-haired woman to choke on her spit in surprise.

"By babies she means inventions," Midoriya clarified, getting a sigh of relief from Iida. "How'd you think you did on the practical?" he asked, trying to steer the conversation away from the awkwardness.

"I think I did well, Midoriya," Iida shared, checking out all the devices the man supposedly made. "This is your lab?"

"Yes, managed to weasel my way into getting one," the green-haired teen admitted. He got her attention as he pointed at the fabricator. "That's the SIF. It's a fabricator," he paused, seeing that Iida wasn't comprehending his wording, "In simple terms it can analyze, design, and construct basically anything."

That got her attention. "Anything?"

"Yep. I used it to build the Iron Man suitcase suit for the practical. That was Mark V, if you were wondering."

"You've made five of them?"

"Well, um, technically no but I like to keep the naming convention in line with the movie versions," Midoriya explained, scratching the back of his head in embarrassment.

"Movie versions?" Tomoyo pressed.

"JARVIS, pull up the video of all the suit up scenes from the MCU," he ordered to a seemingly no one.

"Of course, Sir," came the disembodied voice from the loudspeakers. The video played on a nearby monitor, showing Robert Downey Junior portraying Tony Stark suiting up as Iron Man in various scenes.

Iida (and Hatsume) watched, transfixed on all the scenes and how each iteration of the armor got better and better and faster to put on. By the time the video was over their eyes were large saucers in amazement.

"Greenie! Was that an arc reactor on each of those Iron Man suits?!" Hatsume asked excitedly.

Midoriya nodded, "Yep, the arc reactor can be that small, hell, it can be even smaller," he alluded to as he brandished his EG to them, manipulating the device to show the super tiny arc reactor glowing brightly.

"What?! So you knew it could be smaller when I presented the idea all that time ago?!" Hatsume shouted in surprise.

"Oh yeah I knew, I just wanted to see what you came up with."

"Excuse me, but what is an arc reactor?" Tomoyo asked, skeptical that the man built it, thinking he stole the idea from its true creator, whoever she was.

"JARVIS?"

"An arc reactor is a green energy resource that produces 3 gigajoules per second," his AI answered happily.

"Right," Iida agreed, not knowing how much power that was. The woman saw on a nearby table the pieces of the suitcase suit, the red and silver armor parts being somehow pretty. "I'll be blunt, Midoriya: Why don't you want to be a Breeder?" Iida asked as she held the Iron Man gauntlet from his dismantled suit, examining it in great detail.

"I don't like the idea of being a cum cow for the state or government. I want to help people, can't do that if I'm a Breeder," he patiently explained.

"But being a Breeder is important, Midoriya. With so few males on Earth we need every single baby to recuperate our populations' numbers," she argued, putting down the gauntlet back onto the table.

"If Greenie doesn't want to be a Breeder than I don't see the reason why he can't go against it," Hatsume added, butting into the conversation.

"But it's what males are supposed to be—"

"Let me stop you there, Iida," the green-haired lad interrupted. "Before the 22nd century it was women who were viewed as the lower class of humans, much like how males are viewed in this current age and day. It was a patriarchy back then, ruled by man and only man. Since the arrival of quirks the tides shifted, making women more powerful than their male counterparts."

"Your point?"

"Men don't have to be Breeders, and I'd appreciate it if you could understand my hesitance to be one."

"But it's what you're supposed to be!" she argued, making chopping motions in the air.

"I don't have to be anything!" Midoriya huffed out angrily.

"That's not how the world is going to see it, Midoriya," Iida pointed out as she got up, walking to the elevator. "The more you rock the boat, the more it'll rock back," she warned as the elevator doors closed on her.

"Don't listen to her, Greenie. I believe in you," Hatsume affirmed, resting a hand on his left shoulder. "Besides, we've got babies to make!"

Izuku would've choked on his spit at her wording if he hadn't grown numb to it.

Six days later

"It came in, Mom! My examination results!" Midoriya happily cheered, hoping against hope that he got accepted. He brought the letter with him to his room, ripping it open above his cluttered desk filled with half-finished inventions. A circular round device fell out of it, landing on his crowded desk. The round device lit up and projected a hologram of a small stout-like rodent wearing a suit with yellow/orange boots appeared, a scar on one side of their face.

"Greetings, Mr. Midoriya! Am I a mouse? A dog? A bear? Whatever I am, most importantly I'm the principal of U.A.!" Nozomi cheered. "You scored perfectly on the written exam, getting the highest marks ever in the last thirty years! That alone wouldn't get you into U.A., but you amassed 60 villain points while in your mechanized armor, plenty enough to get into the school," the rodent explained before pausing, "But that wasn't all we were counting! How can a hero school be a hero school without awarding rescue points?!"

"Rescue points?" he asked aloud, wondering where the principal was going with this.

"Rescue points are awarded when you save someone from harm, be it getting them out of the way or getting them out of a tight spot, so to speak. And you, a man," she emphasized with a toothy grin, "gained 100 rescue points from helping your fellow test takers. To summarize, congratulations on being accepted into U.A., Mr. Midoriya! This is your hero academia!" Nozomi declared before ending the holographic display, leaving Midoriya in silence.

"YESSSSSSSSSSSS!" Izuku screamed happily.

"Knew you could do it, master!" Desiree cheered along, turning back to a human to entice him later. "Told you you were worrying over nothing, sugar," she reminded.

"Yeah yeah, Desiree, but I got in!" he said as he gave her a big hug.

It was nice.
