[Drone TF, Sluttification, Identity Erasure]

"Be the best that you can be."

That was the line that had been spreading like wildfire. But not for any good reason. No, the actual reason such a self-supporting phrase kept spreading was because of the drones that kept on saying it like a mantra as they kept popping up everywhere.

It didn't matter how often these drones were beaten. It didn't matter how few or how many of them there were. They just kept on coming. Over and over and over. All while wearing down the efforts of the Pro Heroes that had been doing everything to knock them down.

Even the newer heroes, the former students of UA's Class 1-A, were left on the backfoot thanks to the sheer amount of them that kept on popping up. And to make matters worse, if they weren't fast enough with their response, there'd be more when they arrived. All because of that phrase popping up again and again.

These drones were part of some sort of gang. That much they were able to put together based on these repeat encounters. Their leader? No clue. Their names? Also no clue. The only thing that identified the drones was their identical short black bob cut, and their absolute lack of decency. Tits and ass hanging out like it was something ordinary, while their nipples had a strange ID attached to them.

Each id showed somebody similar to the victim, though the pictures were exaggerated and looked more like the victim had been a bimbo in the past. Which only served to complicate matters when compared with the original self that had been transformed in front of a Hero...

It was one problem after the other. And especially so as more and more Pro Heroes began to vanish. Bit by bit, the forces that were meant to keep these Drones at bay lessened and lessened. Until all that remained were the ones from 1-A. And to make matters worse, they still hadn't found out a reason why these drones appeared, why they were attacking and trying to improve people in this degenerate fashion...

Or if there even was a leader, given the way that these Drones simply popped up every few days. Were they truly connected in any way beyond the way they looked?

1-A's fight continued, as they tried every trick they had in the book. Every little trick to try and put this crisis to an end...

Before they'd end up becoming their best selves as well...

---

"There's just no end to them! Even if we try to smoke them out from the underground, they just find a way to keep getting away!"

Yaoyorozu Momo had done everything she possibly could to try and handle this crisis. As one of the smartest new Heroes, she had more than enough knowledge of trying to handle such a mob. Which was why she had tried to make her friends, the ones that were way more proficient in the art of covering an area to handle the underground.

And yet here she was. Barely holding on, as her body continued to tremble in the face of the never-ending onslaught from all these drones...

It was one thing that their numbers seemingly never reduced. It was one thing that they were both so durable that they didn't go down easy, yet so easy to beat that it never felt satisfying to get rid of one when paired with the wey kept popping up...

But the part that really got under Momo's skin was the way they kept on showing off. She was hardly one to talk, given that her quirk required her to barely wear anything so that she could properly use her quirk. But these Drones all wore practically nothing. The only ways that they covered up their bodies came in the form of their pasties, which just barely covered up their nipples and their holes, and the shiny black gloves and boots that they wore...

Not only were they showing off so eagerly, and acting like it was absolutely normal to do so, but they were also way more stacked than they had any right to be. Tits the size of their heads, if not bigger in some cases, and thighs that could kill a man. Not unlike certain other Pro Heroes that were gifted in that regard...

"F-Focus, Momo!" The black-haired Hero cried out as she jumped out of the way of an attack by one of the drones. Losing her focus for little more than a second was too much, because the Drones were ready to capitulate on her weakness.

Even if that readiness also led them straight into the traps that Momo had managed to quickly set up, as the horde of drones in front of her was quickly swallowed whole by a thick metal net. Compressing them all into a ball of horny wriggling, each drone muttering their mantra over and over...

"Be the best you can be..." Momo muttered as she watched the drones in front of her. She couldn't pick out any single identity in that pile. They all had the same black hair, the same boring hairstyle, the same everything. Leaving her to sigh as even a victory like this, where she could restrain all the drones for the sake of study, wasn't able to push her or the others' understanding at all...

Not to mention, saying their Mantra out loud like this was starting to make her tingle. She wasn't... She wasn't going to turn into one if she kept saying it, was she..?

"Be... N...No, Momo. Don't say i-"

She left herself open for just one moment too long. That was all that it took.

While Momo was completely occupied by these naughty thoughts worming their way into her head, she was slammed to the ground. Courtesy of a Drone that she hadn't caught. Not only that, but it seemed like the drone had fallen towards her, given the way that she had been slammed to the ground by the sudden impact...

What was way more concerning than the way that the Drone had caught her off guard... Was the way that the Drone's legs felt around her head. Her thighs were way thicker than the others. Not only that, but they were almost familiar to Momo...

M-More than she would like to admit. And a glance up at the Drone's bust only served to confirm this awkward realization, one that quickly made her face all-too-red...

The ID that was hanging from the Drone's bust depicted a plump-lipped and thoroughly glammed Mirko. A total contrast from the tomboyish woman she was at heart, which was emphasized by the further contrast depicted by the drone. There was nothing that made her look like Mirko. Only really her thighs served as any kind of indicator of who she had once been...

And even that wasn't going to last. Not because the Drone was changing, but rather because Momo's mind was growing foggier and foggier the longer she spent trapped between these thighs...

"Be the best that you can be."

The Mirko Drone said like all the others. Her smiling plump black lips only serving to make her words all the more welcoming, despite the fact that the Hero should be fighting against this. She should be fighting back, trying her hardest to break the older Hero out of her conditioning...

But all that Momo could do between these thighs was keep on breathing in and out... In... And... Out...

All while that mantra kept on repeating inside her head...

"Be the best that you can be..."

Her lips were repeating the mantra. Her plump black lips. Matching the lips of the drone perfectly. Lips that she couldn't stop herself from licking as they glistened like a proper drone's lips should...

Every time she repeated that mantra, her body changed more and more. Her hair dramatically shortened, until she had the very same type of bob cut as the drone that was currently trapping her between her thighs. Her tits expanded, bouncing unnaturally just as the drone's did. Her ass clapping as it grew, echoing out and making it impossible for anybody not to hear her mantra...

Her clothes were absorbed into her body, only to be replaced by the very same set of long black gloves and boots. With her cunt and her nipples covered up by sticky pasties, ones that were abhorrent at truly covering her up...

The final step of her transformation, and the final step of her submission into the same gang of Drones that had been hounding the city, came in the form of the ID piercing its way through the side of her nipple. Permanently attached as a wicked reminder of who she had been.

Even if this Yaoyorozu Momo depicted on the ID had way more blonde hair than the original. Even with her massive silicone tits bulging their way into the photo. Looking much more like a slut than anything else, perfectly displaying the identity erasing effects of the Drones...

Now, the newly converted Drone simply saluted as she was released. Happily smiling just like the Drone that had converted her....

As she became the best that she could be…

"Go to hell! And stay there!"

Katsuki Bakugou was starting to run out of steam from using his Quirk so much. Who could blame him, given that the Drones seemed to keep on coming no matter how many he blew up?

It was bad enough that he couldn't find Deku when the outbreak really took a turn. Not that he was going to tell the others that he was the first to check, they'd tease him non-stop if they knew. But for the horde to then turn on him and focus him down despite how many of them he was blowing up at a time?

The blonde Hero panted as his arm gradually grew limp in the face of the encroaching onslaught. It's not that the Drones weren't being blown up, they absolutely were. These fat-tittied huskies were nowhere near a match for him.

But if he blew up one, two more'd appear. If he blew up three, ten more. So on, so forth. It's like they found a way to replenish their numbers the moment he launched an attack. And even though he blew up more and more of them, they somehow still managed to make more!

"Damnit..! Damnit!" Bakugou shouted as he grit his teeth. He'd be damned if he was going to give up then and there. He still had fuel in the tank, even if it was going to start costing him.

All he'd have to do was blow up the nearby area, which was safe enough given that the civvies had either been turned or evacuated, and then bam! Problem solved, at least for the time being. It'd give him time to regroup with the others.

At least that was the plan. Right up until the moment a shadow got cast on him, forcing him to look up to see what was trying to block out the sun. He didn't want to get caught off guard in the middle of a big play...

Unfortunately, the sight of the fat tits that were falling right towards him was more than enough to shock him for just long enough to break his concentration. Even if he tried to blow up the space in front of him to knock him out of the way, Bakugou simply wasn't fast enough.

This moment of pure weakness was exploited, as the blonde boy let out a yell of pure anger and frustration at being outplayed by something he could never have imagined. Slammed to the ground, and even stuffed into the gap between those tits...

A gap that grew smaller and smaller as he was yanked along with them, with the soft giggles of the drones growing louder around him as he was reeled in...

"You damn freaks think you've got something on me-"

Bakugou fell silent as he was freed from the tits. It was a quirk, that much he could tell from the way they grew. But the art on the ID that was attached to the Drone's tit? The bimbo that was puckering her lips for attention?

Hardly any different from the actual woman that usually used it. It was Mount Lady, just even more bimboed up than usual. But she was hardly the only Pro Hero that surrounded him. Several more were just like her. Both identical at the moment, and nearly identical when it came to being bimbos on their IDs...

And to make matters that much worse for Bakugou, one of the ones that was about to descend upon him was...

"BASTARDS! YOU WON'T GET AWAY WITH THIS! I'LL KILL YOU!"

His Mom was one of the Drones. And despite the obvious concern that her Son showed towards her with this display of violence, she didn't react.

After all. She was a Drone. And so he should be as well. He had to be the best he could be. Just as she was.

The many identical drones each forced themselves upon Bakugou. Their tits expanding, not to the same exaggerated level as before, but large enough that he could be completely trapped within their warm and sweaty busts. Trapping him, and exposing him to their scents...

Their intoxicating, mind-melting musk. It was bad enough that he had to smell it whenever he destroyed a Drone. Now that he was stuck in between several of them... He... Heeeee....

A bit of drool ran down Bakugou's lip, the cockpillows rapidly developing as he breathed in more and more of that musk. In fact, his transformation was much faster than normal, given the sheer amount of Drones that was part of his conversion.

So much so that it didn't take long for something to go awry. Not for his benefit, but rather for his continued demise.

A loud BANG went off inside Bakugou's brain as his Quirk turned against him, his eyes rolling into the back of his head just as his hair turned the same length and shade as all the drones' hair was. All while his clothes exploded off him as well, his feminine figure explosively developing until it was just as curvy and as impressive as that of the others...

All complimented by more and more explosive sounds ringing through him. He was being blown up by his own Quirk. Blowing away more and more of his inferior self, to make up for how he had been blowing up the Drones that knew they were their best selves...

Until nothing remained of the man that had once been Katsuki Bakugou. Right now? The only thing that he was...

Was not a He. Far from it. She was a Drone. A drone that had just as big a bust as all the others. Even more so once it grew to match theirs, the Quirk that they all possessed now replicating within her. Just as she replicated their natural salute as she was pulled free from all those tits.

Just as all the others, this Drone had an ID attached to her nipple. One that depicted the bimbofied version of the Man she once had been. A grumpy, yet slutty bimbo with big explosively eye-catching cocksuckers, the Drone's own paling in comparison.

But she didn't need to be a Bimbo. She simply needed to be a Drone.

Because by being a Drone, she was the best that she could be...

"The line's dead. And they just keep coming. They're pulling out even more tricks too..."

Shoto Todoroki was in a similar situation to his former classmates. Trying to handle the onslaught of naughty Drones that were coming his way. While he was pacing himself, even trying to create distance between him and the Drones so that their newly manifested Quirks wouldn't be able to pin him down, even he had his limits.

It was why he was trying to play keepaway. Why he was hoping that these explosive Drones weren't able to put together a proper plan to isolate him. And why he was trying his best to figure out a way to get back into contact with the others.

Fact of the matter was, the longer the fight went on, the more Drones joined the fight. Every few dozen Drones, and every few hundred repetitions of that infernal mantra, a new Quirk popped up. One that every single Drone was able to use. Before, it was the growth Quirk that could very quickly get consumed in favor of a quick powerup. Something resembling a combination of Mount Lady and Fatgum's Quirks. Not to mention the clear way some of them had begun to use Momo's quirk, with the way they were rapidly able to produce weaponry or other tools to break through his barricades. And now that they had this explosive quirk...

"The longer we fight, the more time they have to absorb us into their ranks. And from there, they can use our Quirks. There's only two Quirks I know of that are able to facilitate something like that..." Shoto muttered, not at all happy to think about it.

Because one of those Quirks had vanished. And the other... The other was supposed to be gone, and had resulted in Midoriya's departure from the field of Heroes.

It couldn't be his fault. He was the best of them, so why-

"Be the best that you can be."

The mantra wormed its way into his head. All while a sudden chill wrapped around him. A chill that he quickly burned away as he used his burning powers, all while trying to pull himself away from whatever had caused this chill...

Unfortunately, he couldn't get away. Partly because of an explosion that just formed behind him as he was about to do so, but also because of the Drone in front of him, and more importantly, the ID that was attached to her nipple...

"Sister..!"

Fuyumi had been turned just the same as the rest of them. It wouldn't be impossible to imagine the rest of his family had been turned as well. But she was here for him specifically. Showing him the multi-colored bimbo lips that she would've had, if she hadn't become a Drone.

And the absolutely dull yet happy expression that she now wore as a Drone. A Drone who eagerly pulled him closer, eyes dim from the lack of free will able to shine behind them. She was cold, far colder than she ever had been before...

"Be the best that you can be."

She said it once again. The Drone didn't want him to forget. None of them did. But it was the way she spoke it this time that happened to have a much greater effect on him.

Not because it was actually making him consider being a Drone. But rather, it was like her words had frozen inside his head. Preventing him from thinking of anything else, as his attempts to fight back against her rapidly faded away. The misty musk around her that was aiding her in freezing his mind certainly didn't help...

All that Shoto could really do now was stare up at his converted Sister, panting slowly as the mantra spread further and further through his mind. He certainly tried his best to fight back against it. But all he could do was just sit there. And stare up at her. Stare and stare and stare...

As bit by bit, he grew more and more covered in ice. Absolutely unable to do anything as his very existence as a male got frozen over. Not a single speck of his individuality discernible through the thick pane of ice that covered him, as he ended up in what could best be described as an icy coffin...

An icy coffin that the many Drones gradually began to rub up against. It didn't matter that it was icy cold. They could feel an incubating Drone within. So they had to free her. By giving her all the body heat that she could ever need.

Bit by bit, the ice started to melt once again. Revealing his...

Revealing her body to the Drones. A body that was just like theirs. With hips as wide as they needed to be, so that anybody could be distracted by the way that they shook them. With tits as big as, if not bigger than her head. So that anybody that looked at them could be taken off guard by the way they swayed. With a bob cut so plain and identical to the others that she would never be mistaken for anything but a drone...

And once the ice melted completely, there stood yet another Drone. Identical to all the others, despite the fact that she had been a very special Hero just a few minutes prior. Now, those special powers were part of a whole. Nothing more. Nothing less.

Just as she was. Saluting happily, ignoring the two-toned gyaru bimbo that was printed on her ID. White and Red became Gold and Pink, which perfectly matched the kind of slutty vibe that Shoto had once gone for. That is, the 'Shoto' that would naturally become this heavy-tittied Drone.

The sheer contrast between her current Drone self and her 'Former Self' was arguably even bigger than the contrast between her and her former male self. Not that it mattered to this Drone. Because nothing but her orders and the spreading of the Drone nature mattered to her.

After all, she was now her best self. And others should be their best selves as well, joining them as one completely identical whole...

Their best selves, all of them…

"Where... Where am I? What happened? The last thing I remember was going to Izuku's to make sure he was okay..."

Uraraka Ochako was having one terrible, terrible headache. She had been overwhelmed by the Drones, but she managed to use her Quirk to stun a lot of them before escaping. And since Midoriya didn't have any powers to call his own, at least not after everything that had transpired, that meant that he was in incredible danger...

And yet she couldn't remember anything of what happened when she arrived. It was one big black void. The last thing she could remember was opening the door, and then nothing...

"You were given the chance to be your best self, Ochako."

A soft voice, a friendly voice. One that immediately sent chills down the brunette's spine as she heard it. She couldn't believe what she was hearing. But there was no other way around it, was there..?

She gazed forward. Straight into the eyes of yet another Drone. One that had seemingly waited for her to awaken. And while it was just like all the others, the ID that hung from this one's nipple was... N-No, there was no way...

"Izuku!? T-They got you!?" To say there were a lot of emotions going through Ochako at this point was an understatement. And the musk that was in the air didn't help matters at all, her body trembling with lust as she breathed in more and more.

That Mantra, now repeated with Izuku's feminized drone voice, growing stronger within her mind. Repeating. Over and over and over. Awfully compelling...

"You misunderstand." The Drone that had once been Izuku, once been Male at that, simply smiled with those plump black lips of hers. And offered a hand to the girl that would become one as well soon. There was no way to escape her fate. But that didn't mean she had to succumb to it just yet. "I was the first to turn. The first to be given a new role by our Mistress."

Mistress... That's right, there was a person behind all of this, there had to be. And Izuku had... Izuku had brought her to meet her? Oh. Oh, that wasn't good at all. That meant that...

That meant... That....

A bit of drool started to pour down Ochako's chin as she struggled to keep hold of her mind. It was hard to do so when faced with the musk in the air. Much less Izuku's bimbofied face looking at her from the ID. And the Drone's smiling yet blank expression not helping either.

"Very well. It seems as if you've begun to turn. No matter. I can guide you. Mistress would've wanted me to do so regardless." The Drone said, lifting Ochako up like it was nothing. Just as she would've done back when she still had her Quirk.

Ochako couldn't think clearly as she was helped up. No, the only thing she could think of was that Mantra. And the wonderful sensation spreading through her as it repeated, as well as the smell spreading through her and making her even hotter...

It also didn't help that as they kept walking, they saw more and more drones just like Izuku. More and more huge-breasted drones that didn't have a single independent thought in their heads. Just the need to spread the gospel. The need to keep spreading the mantra that made them the best that they could be.

She could barely even make out what was on the various IDs. But a lot of them unfortunately showed faces that she was intimately familiar with. So many friends and allies that had ended up bimbofied. Most of them belonging to her class. Which meant that most of them...

No, not just most of them. All of them. And she was going to join them soon too. She was going to end up with tits that were bigger than her head. Tits that were going to sway lovingly back and forth and draw in the vulnerable. So that they would be mesmerized. Completely and utterly hypnotized, unable to do anything except keep watching...

Just like the Mantra, these swaying tits, which were gradually becoming her own tits at that given the transformation gradually worming its way across her heavily heated and thoroughly aroused body, were now stuck in her mind. Making her drool more and more as she was dragged along...

Until she came to a stop. Because the Drone stopped carrying her. She just stood there as the Drone opened a pair of double doors leading into what seemed to be a villain's lair. This... this was where her Mistress...

No. This was where Mistress was meant to... be..?

Ochako blinked a little as she slowly stepped inside, guided by her fellow Drone because otherwise her body wouldn't even think of doing so. And what was she greeted with? A mighty Villain that had managed to turn the former wielder of One for All into a Drone that then caused it all to spread? A vengeful former Villain who turned her feelings on everyone else because of what they had done to her..?

No. The only thing that was in this lair was yet more Drones. Not a single one of them standing out in any way. Not even the one on the throne in the back. She couldn't even make out an ID on that one, but that wasn't new. There were quite a few that didn't have IDs. Mostly those that didn't have Quirks in the first place, or otherwise weren't notable...

Which... What did that mean..? She couldn't think coherently, much less form an opinion to call her own. So she couldn't possibly know what this meant...

"Mistress turned me into a Drone. By making me the Best that I could be. And the last vestiges of One for All sparked back to life. Mutating into something new. You're familiar with it, I know you are."

... Ahhh... Ahhh...

Ochako... No, the transforming Drone breathed in as it gradually became apparent. Yes. That was what the Drone was talking about. How could she and the others not have realized it, once they saw how the other Drones were able to use Quirks that weren't theirs..?

The transformation itself... It was One for All being imposed on them. Merging with their Quirks. Merging with them. Just as it had done so many times before. To many more before them.

"Mistress told me to use Drone for All to make everyone their best selves. So I did what she asked. And now she's the best she can be. Just as you will be the best you can be."

The Drone explained. And it all made sense. It all clicked into place. There was not a single question left in the Drone's weakened mind.

The only thing that remained was pure pleasure, as she let out a deeply delighted moan. Consumed by Drone for All, just as the Drone had told her that she would. Not that there was much left in her to consume or absorb, because she had already been overdosing on the musk over the last little while...

She who now had forgotten all about her original identity as Ochako... She simply giggled with that same dull yet happy expression as everyone else. And saluted, as she ended up just like all of them had. With a bimbofied body wrapped in terribly little actual attire, and an ID that matched the kind of body that she had.

A Gold Digger like her was just as tanned and as glammy as a bimbo could possibly be. Completely excessive in every way, to the point where her tits very nearly took up all the real estate on her ID. But that didn't matter to her. Because the Drone didn't even think about her former identity.

She was the best that she could be, after all. Why should she worry about who she had been? That was for others to worry about. And once they came close enough to see who she had been, Drone for All would claim them just as it had claimed her.

It was a constant cycle. No matter how many of them were destroyed, they'd reform due to the Quirks they had become melded with. All so they could come closer. Closer and closer, to the ones that still weren't the best they could be.

So that they too could be absorbed into the mantra. Absorbed into the delight they all felt.

So that they could be the best they could be...
