“Young Midoriya, young Bakugo,” All Might had said to them as they began, “Throughout your life, and especially as heroes, you will need to learn to work with anyone; even those you might dislike! Take this, young heroes, as a learning opportunity!”. 

    He had tried to be inspiring, even taking his muscle form for a few moments to drive the point home. But, well, his little book of teaching advice couldn’t have been written with the sheer hostility the young blonde boy bore his childhood victim in mind, or how the two would constantly bicker and fight. Admittedly, it also wasn’t written with heroes in mind in the first place, but so far most of the advice had been holding up. 

    It had been a few weeks since Bakugo had gotten his provisional license, and of course shortly after he got into another brawl with Izuku. This time, as they both had licenses and could thus do hero work, it was decided that the natural punishment would be to force them to work together. Worst case scenario, nothing changes and they try to avoid having to do all that again. Best case, they end up understanding the need for some professionalism if they can’t be amicable. 

    At least, that was the theory. As he watched the pair headed out, in their hero gear on a simple patrol around the city, he wondered if that was the right call after all. They were already bickering as they left…

    Nah, of course it would be fine. 

    “Just two more streets…” A certain green haired and costumed hero said, a few hours after the pair had left the U.A. campus.

    “You don’t have to tell me that, idiot, I can read the signs!” Bakugo shot back loudly, before turning away grumbling, “Let’s just get this over with…” 

    It had been a rough patrol, to say the least. Deku had tried to be conciliatory or at least professional, but that just pissed Bakugo off more. He was absolutely incensed that he had to work within a hundred meters of his rival. Thankfully, they hadn’t actually encountered any trouble more complicated than helping the elderly cross the street or giving some directions (which were admittedly a bit rough on Bakugo…) and so it was likely that they’d make it through without incident…

    “I’m just glad this is over, and I won’t have to work with a crappy hero wannabe like you anymore,” Bakugo continued as they turned the corner and could head back towards U.A. 

    Deku took a deep breath. Months ago, when he first started out, he’d have recoiled from that kind of attack. “You know why they put us on this patrol together right? It’s not just supposed to be a punishment-” 

    “It’s supposed to be teaching us to work with anyone, yeah?” Bakugo retorted, “Well, that’s pointless! Why should I have to work with someone like you when I can just do it myself? All Might doesn’t need help to be a hero and neither do I!” 

    Deku was ready to respond, but before he could there was a shriek of terror from nearby. For all their differences, he and Bakugo’s reaction was the same: sprint down the alleyway from which the sound came at full tilt, because it might be someone in trouble or a crime in progress. 

    It turned out to be the latter. Down at the end of the alleyway there was an unconscious woman with a figure standing over her. All that the pair could discern about the figure was that she was female; anything beyond that was obscured by the dark, heavy cloak she wore.

    “Hey! Bitch in the dumb ass cloak!” Bakugo shouted.

    “Get away from her!” Deku continued, a bit more reasonable.

    The figure turned, and smirked. “Ah, just as I hoped, a delightful pair of young heroes…” the woman said. 

    “What’s going on here?” Deku said, already running through his memory. This woman didn’t seem familiar - he looked over villain databases almost as much as hero ones. But the cloak was hefty enough to conceal her, so it was hard to recognize anything.

    “Oh, I just wanted to lure in some new merchandise. Please, call me the Collector, for the few minutes of independent thought you have remaining.” The woman said.

    In many other circumstances, that would have caused Deku to pause and think. The Collector definitely wasn’t in any villain databases he was aware of, which meant a complete unknown Quirk. The woman on the ground didn’t show any obvious signs of what Quirk might have been used on her, and her current state could have been brought about in hand to hand. But what she said - hoping to be found, something about merchandise and taking away independent thought. Mind control quirk? Something else? What was the trigger, speech or touch or a look into her eyes? 

    If he’d had the time to think about it, he might have gotten away. But there was someone in trouble, and he had to save her - and besides that, as he’d paused with caution, Bakugo had already started off on her. “You’re real annoying, ya know that?” Bakugo shouted, before promptly blasting off towards her, with Deku activating Full Cowling and jumping off after him. If they took her out quickly, then she probably wouldn’t get a chance to activate whatever her Quirk was.

    The fight was over in less than five seconds. She managed to slide under Bakugo’s first blast, the tips of her cloak getting a bit singed as she went under him. But he had superb control of himself in the air and managed to cancel his forward momentum and whirl around to throw an explosive punch at her. This was coming in at just about the same time Deku’s foot, arriving just a little after Bakugo due to jumping a bit late. At nearly the same time, they made contact; the Collector managed to bring her hands into position to guard against both attacks, but the high force coming from two different directions and heights sent her sprawling prone, the two heroes nearly colliding. 

    As the pair recovered, Bakugo whirled on Deku. “You idiot, you nearly flew right into me! I didn’t need your crappy ‘help’!” 

    “You were the one who rushed in without a plan!”

    “I had a plan! The plan was ‘blow up the villain!’ And it was a great plan!”

    Deku was about to respond, when he noticed something. “Has your hair always been that long?”

    “Are you blind and dumb now? Look who’s talking.” Bakugo shot back. 

    Deku wasn’t sure what he was talking about, until he brought his hand around to his neck and felt more hair there than there usually was. “What in the world…”

    Suddenly, a mad laughter filled the alleyway, as the Collector staggered to her feet. “Man, you nearly got me there kids…” she managed between laughs, coughing a bit, “That’s a real good tag team you’ve got going there… if I was a bit less tough I’d have been knocked out and you’d win…” 

    “I’m not on any kind of tag team with this crappy wannabe!” Bakugo shouted, but the Collector continued without taking notice. 

    “But, well, you didn’t, and you made the mistake of touching me. Guess I win~” she taunted. “Since it won’t matter, I’ll give you a hint about my Quirk. It’s called Real Life Modeling, and you can take a guess at what it lets me do to the people I touch!” Of course, even if they didn’t want to guess they would soon find out, as their bodies shifted and changed. 

    Deku’s hair continued to lengthen, as well as rapidly shifting in shade from his natural dark-green towards black, smoothing out towards the top and getting even spikier on it’s way down to his hips. Bakugo’s hair also lengthened, but it stayed the color as it straightened out and gained volume down on it’s way to his bottom. “What the hell is all this!?” he shouted, feeling the sudden weight on his head. 

    “It must be her Quirk - we have to take her down before any more-” Deku was about to suggest finishing her before she could change them more, but as he turned to leap at her he stumbled. His body didn’t have the right proportions anymore as he suddenly gained several centimeters in height. 

    “Ha! Dumbass, I’ll do it!” Bakugo declared before also stumbling over… although in his case, it was because he’d lost several centimeters, and was now significantly shorter than Deku’s new height. “Hey, Deku, what do you think you’re doing being taller than me, huh?” 

    “I don’t exactly have a say in this!” Deku shot back as the changes rapidly continued. While at first the change in proportion had just been height, other parts of him were changing now too; his hips flared out while his waist pinched in, and his shoulders lost some of their broadness. His legs seemed to take more of his body than before, and his costume was straining to keep up. 

    “Haha! You look like a chic- Wait, crap-” Bakugo started to mock Deku as his own changes came in, and even more rapidly - namely, he had a pair of hefty weights on his chest that hadn’t been there before. “Hey, bitch, why’d you give me tits-” he shouted, but was cut off again as the proportion changes continued and soon he had an hourglass figure to match Deku’s (who’s change had proceeded to include a nice set of knockers himself). 

    Deku tried to remain calm - whatever she was doing, she would be able to undo, or even might just wear off in time. But if that was the case, she should have been taking the opportunity to run. Did the change have a range? Or did she have something else in mind… his thoughts were derailed as he looked down to see that his costume had… changed. His support gear had melded with the suit, and the fabric was shifting and changing from green to black, and a lot more leather at that. He stumbled a bit as his boots became high-heeled, and blushed fiercely as it became clear his clothing hugged his skin. But… something was strange… the outfit started to seem familiar. As a hero nerd, there was no way he couldn’t recognize it. Why was he wearing Midnight’s outfit? “Kacchan-” he started, but his hands shot to his own throat. His voice had sounded incredibly off - or rather, her voice had, as his… uniquely male parts, had receded into his body and been replaced beneath the costume. 

    Bakugo for his part, was still checking out his new body when he saw his costume start to change. Actually, it became somewhat more modest, going from a t-shirt straining against his new melons (or rather, her new melons, given the changes that were happening) to a bodysuit hugging them. The new beige and blue color scheme progressed from her neck down, converting his old clothes and support gear into the raw material for her new look. “You’re gonna regret this!” Bakugo shouted in a more feminine voice as her clothes took shape. 

    “Kacchan, I-I don’t know why, but I think she’s turning us into other heroes-” Deku started, but found it hard to continue as it was her face’s turn to transform. While she couldn’t see it herself, Bakugo watched as her rival’s face smoothed and stretched and changed, leaving nothing of Deku’s appearance behind and replacing it with someone familiar to both of them.

    “Hey, you look like that old hag Midnight!” Bakugo pointed out - not aware of her own change, her face gaining a more feminine cast to it and her eyes went from red to purple. 

    “And you look like Mount Lady!” Deku said, turning to the Collector as the finishing touches were applied to the pair - the jangling handcuffs and riding crop and mask for Deku/Midnight and the mask and horns for Bakugo/Mount Lady. 

    “Oh you turned out delightful!” The Collector trilled, “Perfect replicas. But do you really think you’re done? Perfect replicas don’t sell well.”

    They’d both been going for her again, but unfortunately for them the changes she’d inflicted were not actually over. Deku and Bakugo might have finished turning into Midnight and Mount Lady, but that didn’t mean they were done transforming. 

    As they started to move towards her, their proportions shifted again, waists pinching in to become even more narrow while hips and bust expanded, especially in Bakugo/Mount Lady’s case. Their clothes transformed as well, with Bakugo’s shoes getting significant heels, while both of their bodysuits gained plunging necklines that showed off their busts. Their asses grew out as well, bubble bottoms straining against the bodysuit even as muscles smoothed and faded away to give them more “feminine” looks. Now they weren’t just Midnight and Mount Lady, but sexy caricatures of the two heroines - and being thrown off balance by the new and rapid changes gave the Collector time enough to close with them.

    “As fun as this is, I think that’s enough of that~” she sing-songed as she laid a hand on each of their heads in turn, triggering her Quirk once again. 

    “Bitch, I’ll kill you-” Bakugo/Mount Lady managed, but soon was forced into silence, her face freezing mid-speech as a plastic sheen crept over it. Unlike the first round, she was immobilized because the Quirk wouldn’t let her move, and Deku/Midnight was in no better position as the transformation overtook her head at an equally rapid pace. The plastic look spread from where the Collector’s fingers touched, rapidly spreading over the transformed hero’s heads, freezing their hair in their current style along with their face in it’s expression. The victims tried to move, to pull away while they still could, but the Collector’s grip was like iron and the plastic seemed to drip over their body even faster in response. Heaving breasts froze in motion, while arms outstretched were locked in place before they could attack. With their upper bodies immobilized, their shapely legs couldn’t do anything either and the transformation rapidly froze it’s way through their bodies. 

    “I’m sure, dear.” The Collector responded to Bakugo/Mount Lady’s final words, examining her prizes. She knocked on the Midnight model’s head, a hollow ‘thunk’ resounding; she was nothing but plastic, with a head empty of anything but air. “Hmm, you couldn’t have made this easy and posed for me, could you?” she said with a pout. Of course, they couldn’t answer anymore, although Mount Lady’s distinctly unladylike glower was probably how she’d have responded. 

    The Collector hummed as she worked on the models, getting them properly set up. She changed their expressions from fear and rage to a seductive smirk for Midnight, and a come-hither inviting expression for Mount Lady - those seemed appropriate for sexy caricatures. Then, she got to posing them; despite a lack of joints in the models, they moved smoothly for her as she applied her Quirk to her true passion. For Midnight, a classic pose showing off her buxom breasts and bubble bottom, riding crop extended to threaten a good time to whoever was looking at her. For Mount Lady, a more traditionally seductive pose, emphasizing the curves of her hips and her bust with a cute quirk of her head, like she’s asking the viewer when they’re coming to her. It took forever to get the hair right, moving the plastic masses around until they looked like they were in the right position for the poses. 

    She stepped back to admire her work. They were nearly perfect, two of the sexiest heroines in seductive poses with perfectly exaggerated costumes and assets… just a bit too big. She laid hands on them once more and triggered Real Life Modeling one final time, shrinking the pair to about 1/6 scale, small enough for transportation. Then, she turned to the unconscious woman - or rather, the doll made to look like an unconscious woman - and shrunk that until it was small enough to fit in her pocket, before strolling off. 

    What’s going on? Deku thought. It’s dark… I can’t move… Though he’d still been able to see, the place he was actually in was dark enough he couldn’t. He could still feel his plastic body, and honestly that might have been worse than feeling nothing. If he was out cold then he couldn’t be bored. 

    BITCH! I’LL KILL YOU WHEN I GET OUT OF HERE! HEY SCREW YOU! Bakugo shouted in his mind, but was unable to act on it as the sexy Mount Lady Statue waited in storage. 

    Nearby, somewhere outside of the box they were in, there was a cheer from their captor. “And sold! Girls, you’ve got a new owner~ It’s almost sad to see you go… but well, girl’s gotta make money...” 

    One of the words struck a cord with the both of them, even if they didn’t want it to. The change had started to settle in, as the hours passed and the change grew harder and harder to reverse… 

    Owner? Deku/Midnight and Bakugo/Mount Lady thought at the same time. It was a word that they should have been repulsed by, but it was strangely intriguing. 

    What does she mean owner…? Did she sell us? I wonder to who? Are they a fan- wait, what? Deku/Midnight thought. 

    “Shipping will take a bit. It’ll probably be a week before you see him. Which is just as well, since you’ve only a few minutes left before we hit the 24 hour mark…” 

    Only one who owns me is ME, even if I’m just a model- the hell was that thought?

    “Fun, I think he’s a UA student! I wonder if he was in your class? Of course, there’s no way he’d recognize you now.” 

    It’s a boy, then? I hope he admires my figure- that sounds… huh…? The Deku-Midnight Model thought. Something was wrong, but she couldn’t place it. 

    That perv! I hope he gets a good look at my tits-! The Bakugo-Mount Lady Model on the other hand, didn’t notice her slip as she angrily ranted. 

    The clock ticked over and started to chime, marking twenty four hours since Deku and Bakugo’s transformation. The Collector started preparing them for shipping, their transformation locked into permanence. 

    “Oh yes, oh yes!” Mineta cried with joy as he brought the package into his room. Honestly, he’d needed to treat himself; even he was upset with how Midoriya and Bakugo were missing. But with his new prized possessions he could forget about it for a bit, and revel in the sight… 

    He opened his package and carefully, reverently lifted out the two models, one in each hand, of his favorite heroines: Midnight and Mount Lady, the two sexiest heroines in the business. He’d already prepared a place of honor for them on the shelf next to his bed, lit by a purpose-placed lamp, so he could look at them each night in bed. 

    This is Owner… The Midnight model thought with a pleasure that matched her frozen expression. The model - who couldn’t even conceive of being anything else - was even more excited than she’d thought she would be. Since the day of her creation she’d yearned to be admired by an Owner, to be loved and desired. And now she had one, who clearly loved her very much with how he rubbed her chest on his face. 

    Master~ Master~ The Mount Lady model trilled in her mind as Mineta rubbed his fingers between her thighs. He was as adorable as she’d hoped, not that the model could even begin to think negative thoughts about her beloved Master. Creator was right, there was nothing better than having a Master who loved her. 

    The two former heroes, now loving models, were gently placed on the shelf. While the plastic of course couldn’t move, it almost seemed like they pushed their chests out a bit more, emphasizing their figures some more. They certainly wanted to. 

    Aaaaaha~ this is wonderful~ Owner, look over here! The Midnight Model cried in her tiny little mind, Delightful owner, look at your perfect model~ take in every millimeter, I’m yours!

    The Mount Lady model couldn’t hear the thoughts of her rival for her master’s attention, but she had much the same thoughts. Ehehehe, there’s nothing like having Master’s loving gaze on me~ she thought as Mineta looked over the two of them with a lecherous glint in his eye, Eat the eye candy master! It’s all I was made for~! 

    Mineta took a few moments to rub both of the models, as if to prove to himself they were real. They were so realistic, like they could have sprung to life to service him at any moment, and that was certainly a thought he’d be taking to bed that night - which of course, would have delighted the models to know. 

    There they would remain for as long as Mineta was at UA, and then they’d go wherever their beloved owner brought them, always in bliss as long as they pleased him and never even considering that they might have once been something else; which was just as well, as after the first 24 hours, the transformation had become permanent; even if she were to change them back, they’d just be models in human bodies. 

But that was irrelevant; all that there was to them was Master’s pleasure. And that night, they would be the source of quite a lot of pleasure indeed.
