As Izuku could have predicted, the ride to the hospital was fairly awkward, All Might and the greenette just sitting in silence in the back of the taxi while the driver sat completely quiet himself, staring ahead with no more than a schooled expression of confusion.

Still, it seemed being a taxi driver had brought him many similar weird moments as Izuku's sudden skirt dilemma if his small mutter of 'Why is it always me' was anything to go by.

It was only a short five-minute ride fortunately, though the dread only built for the now blushing teen as the hospital came into view, as he would now have to face people dressed like this.

"Thank you for the lift." All Might said to the driver, handing over some yen while Izuku just clambered out and gripped his new skirt tight as his face continued to heat up. "You ok, young Midoriya?"

"Three guesses." He commented quietly, not meeting his mentors eyes. It was one thing, the man seeing him with context as to what happened and where there was no strangers around but as soon as they walked into that hospital…

It set his nerves on edge a little, even if a more logical part of his brain that was currently buried under his embarrassment was trying to remind him that there was no real reason to worry. Tiger of the Wild Wild Pussycats wore a full feminine get up and no one questioned him other it.

Then again he wasn't a known pro adhering to a theme of a group so….

"I'm sure it will be fine, just focus on the bright side. The flight or the strength., focus on one of them instead." His mentor advised as they walked into the main waiting room. Izuku did as the blonde said, though he still felt uncomfortable when he felt multiple sets of eyes linger on him for at least a moment.

He began to slow down as they neared the front desk, letting All Might deal with explaining. As he stopped, hands clasped together, he overheard something rather interesting.

"Is that kid wearing a skirt?" One man whispered.

"Yeah, looks like it." The woman beside him confirmed with a hum, seemingly uninterested. "Good for him I guess, I'm more interested in how he takes care of those horns."

….Eh?

"What horns?" 'My question exactly, mister Stranger.'

"Those ones on his head." She gestured, trying to act subtle about it. Confused, the greenette reached up and felt around his head, only to find nothing of the sort.

"…Are we looking at the same kid? That blonde one doesn't have any horns."

'Ok, what?' Izuku looked around for anyone other than him in a similar outfit, only to come up with nothing.

"No? I'm on about the black haired one? See, pitch black skin and horns."

"…We're both definitely seeing the green outfit right?"

"I mean yeah, that's obvious. Why are we seeing different things? A quirk?"

"Probably."

With that, their conversation wrapped up leaving the subject of said discussion absolutely bewildered. Neither had gotten any part of his looks right aside from the outfit, go figure, yet it was plain to see they must have been talking about him from context clues.

Then it occurred to him what All Might had said earlier about him looking completely different. 'Maybe that's a side effect, then? Some kind of perception filter, hiding what I really look like to others? Well at least that means no one will recognise me from school if I run into them.'

"Young man, it's time for us to go." His mentors voice suddenly brought the greenette out his thoughts as the skinny man gestured to the doctor beside him with a serious expression. "They wish to handle this immediately due to the nature of this… situation."

Izuku nodded, following the two through the halls, the doctor pulling off ahead of them by a short amount. As it turned out, that was for the best as Izuku noticed his mentor begin to stumble as they walked along, as widening as he moved to the catch the man. "All- I mean, uh-"

"Yagi." All Might supplied through a pained breathe, Izuku nodding.

"Are you alright, Uncle Yagi?" The teen asked, getting a confused look from the skinny man which he just shrugged in response to.

"I'm fine… just shouldn't have pushed myself earlier." He said with a sigh. "Delayed pain, it's pretty irritating."

"I can imagine." Izuku hummed with a barely masked hint of concern, helping the older blonde to his feet. The doctor looked back before quirking a brow. "He's not got the greatest balance, accident from a few years back. He'll be fine now, just nearly tripped."

The doctor seemed to buy it, turning and walking into the office, the teen and pro following him in. It was rather standard for a doctor's office, except for one thing.

There was a door leading into what was a massive training field essentially, visible through the glass. Izuku remembered it from when he was a child, though he never got to use it due to being quirkless.

"So, first things first, I'm doctor Ikari. May I please have your names?" Ikari asked. He has light brown hair, tired golden eyes and a rather minute figure that seemed surprisingly unhealthy for someone who worked in the medical field.

"Toshinori Yagi." All Might spoke first, watching the brunette write it down before their gazes shifted to the greenette.

"Izuku Midoriya."

Suddenly, both the pro hero and the doctors faces briefly lit up in shock. Izuku raised a brow in confusion, an emotion that only grew with what doctor Ikari said next.

"Did you just shapeshift?"

"N-No? Why?" The greenette asked, looking to either of them for an answer.

"My boy, you have looked completely different up until you said that. Now you look like yourself again." All Might explained, inspecting his student curiously.

"So this is how you are meant to look then? Green hair and eyes?" the golden eyed doctor asked, getting a nod from the teen. He quickly scribbled down that bit of information. "Interesting, I had been seeing you as a blue haired muscular man moments ago. Rather reminiscent of Tiger from the Wild Wild Pussycats really If you know of them."

"I just saw a ginger kid with yellow eyes and a few scars." All Might muttered, getting an odd look from Izuku.

"So… I also heard two people talking outside and they saw completely different things themselves looking at me." He explained, turning to the doctor. "They both saw the same outfit though."

"Hm, well we can return to that chestnut later." Ikari decided, moving to a nearby drawer and pulling out a machine of some description. "For now, I think we should begin some tests…"


"Alright, come on, don't even think about trying any of that funny business with trying to slip through the bars again." A gruff voice called into a pitch black room, before suddenly light spilled in through an open door.

A few police officers walked in, grabbing the cage that contained Hedoro Viran, or as the media had taken to calling him, the Sludge Villain.

Truly, the media were such creative geniuses, he thought bitterly from the cage he sat imprisoned in that was moved out into the street.

It was the day of his transfer to a new prison since he'd been defeated by All Might and he just wanted it to be other, as he had to be brought through the city that was the site of his defeat.

"I couldn't even if I wanted to." He explained futilely, aware no one was actually listening as he glared ahead. The cage had certain suppressants on it that quickly tore his sludge apart due to the limited amount he had to use, stopping him from escaping.

He let out an angry huff. It was all that stupid brat's fault, and the symbol of peace. If neither of them had shown up he could have been safely enjoying his life with all his stolen goods instead of locked up like an animal!

"Let's try to make this-"

"OKANO! WHAT THE HELL IS THAT?!"

Hedoro's gaze turned skyward before his gaze widened in shock at the rapidly approaching black lights that burst through the air…

…Straight at him.

"IT'S GOING TO-"

They hit and there was a sudden explosion of darkness, before a cruel, high laugh rang out through the air.

And the next thing anyone knew, everything began to drown in slime.


An hour later saw Izuku in the training field, a few small microscopic sensors attached to him as he stretched his arms and legs. Nearby, both All Might and Ikari watched on, one concerned and the other with budding excitement as they observed a live X-ray of Izuku's body.

"Ok, doc…. Mind running me through that one more time?" All Might asked, arms crossed. "Because if you're saying what I think you are…"

"Alright, so this here, this little section near the stomach?" Ikari pointed out on the machine an area just around the same place the greenette's lungs would be. "This is commonly thought to be where a thing that I can only describe as 'quirk energy' is produced. It has more technical names of course, but that's keeping it simple.

"Think of it like electricity if you would, in its initial state it's just pure energy coursing through the body but once an emitter quirk or transformation quirk is actually activated, it changes to do very specific things. Like how electricity can be used in headphones to deliver sound.

"Consider the recent debut pro, Mount Lady. Her quirk turns that raw energy into a form that allows her to grow exponentially. The interesting thing here Is that though mister Midoriya clearly has powers now, he isn't producing any 'quirk energy' at all, nor is there anything stimulating that area."

Ikari then pressed a button and the overview of Izuku's body changed, showing a black silhouette but inside, there were three obvious white lights in his body, spreading throughout him. The golden eyed doctor then pressed another button and each white light lit up a different colour. The one that dominated most of the body was green and still, the second biggest light was pink, swirling about a small amount but not really moving and finally the smallest one that seemed to be moving somewhat erratically inside the teen was blue.

"This is where things get really interesting, mister Yagi. You see, my following theory after realising Midoriya's own quirk energy wasn't being stimulated or really even exists more than as a small residual amount from his parents was that the quirk energy then must exist in these light rays. It took quite a bit find a way to track them but using a UV scan of his insides I managed to find what you see here. As you can see, the green ray for whatever reason is currently dominating over the other two which are simply sitting around, not really contributing at all at the moment."

"Fitting, I guess." All Might said with a small laugh despite himself. Of course it would be the green one.

"Yes, well, anyways I scanned them with every test I could think of… nothing. There is not a single trace of 'quirk energy', foreign or otherwise in these light rays. There is something… powerful in them but, whatever this is, it is not related to quirks at all." Ikari finished up, taking in the bewildered and concerned expression of All Might. "So, I think it's for the best we test mister Midoriya's abilities now, because there is no other way we are going to learn about them."

Izuku stood straight at that, mind racing with the implications of what the doctor had revealed. Ikari showed them both a timer, a grip strength machine and even a large machine that had a display which was currently switched off and a pressure pad of some sort on its side.

"Alright Midoriya, here's what I want you to do. Five laps around the track we have here, the machines on your body will automatically track the time and calculate your speed at the end. We're going to do this twice, once with you staying on the ground and a second time with you flying, to see how much of a difference there is if any."

"Got it!" The greenette nodded, positioning himself at the start line in the innermost lane and taking a deep breath. "I'm ready."

"Then… GO!"

And in an instant, the two men were greeted to the sight of a green blur surrounding them in mere seconds, the wind causing the blonde's long hair to billow slightly.

Suddenly the greenette stopped in front of them, a massive smile on his face as he hopped around. "Holy crap that felt so amazing! I mean how fast did I even go!? Everything looked like it was in slow motion and it felt like everythignwastakingforeverbutatthesametimeit'slikeitwasninstantandovernotimepassedatallandthatssoweirdand-"

"Izuku!" All Might quickly grabbed the greenette's attention with the use of his first name, as his features softened and he smiled. He couldn't blame the kid, he remembered the first time he'd utilised One for All's speed. "Still have other stuff to do remember?"

"O-Oh, right!"

"I must say though, even without the introduction of flight these numbers are beyond impressive." Ikari hummed with a glint in his eyes, as he showed the two the board with the times on it, making their jaws drop. "Mister Midoriya passed a lap roughly every one point five four seconds for all five laps, his finishing time a cool seven point seven one. Do you know what that means, either of you?"

Izuku's eyes lit up bright in an excited glee as he instantly worked out the math. "Wait doesn't that mean I was going over five hundred miles an hour!?"

"Correct!" Ikari laughed, unable to hold back his own excitement at what they were getting to witness. He showed them the numbers, glee obvious in his voice. "More specifically, at least according to the machines, you reached roughly a top speed of five hundred and eighty miles per hour from running alone! Now, we have to test flying!"

"Oh uh… can I have a moment, doctor Ikari?" Izuku asked with a small frown. "I've not really practised at all so… I'd prefer to get used to it a little first to be safe?"

"That's fair enough, I want to bring up a point to your uncle anyways so feel free to practice." The brunette encouraged, before turning his attention to the blonde while Izuku began hovering before flying around in circles. "I want you to look at those light rays."

"Huh?" The skinny blonde raised a brow in confusion but did as he was told, checking the lights. "What am I looking for?"

"Note the green one, it's brighter than before but the others remain untouched. A quick check confirmed that while they are somewhat weaker than the green one, they still possess extraordinary strength that isn't being utilised at all here. There is more to his powers than I believe we will see today. Based on this vibrancy though, I can tell you one thing for certain… these powers, at least as long as they continued to be used… they will be sticking around."

"Wait…. So I have powers for good?!" Izuku suddenly asked as he hovered down with surprising grace, as if he'd been flying all his life and not just for ten minutes at most today.

"It would appear that way, yes. Congratulations, I suppose mister Midoriya. Of course, I expect there is still more to find for now, so if you would?"

"Ah! Right…."

He took his place at the starting line once more, and they followed the same song and dance again but this time Izuku stopped a little bit sooner in front of them, all eyes turning to the board to see he'd only taken seven point one seconds this time. At the bottom, there was an estimate of his top speed.

"Six hundred and thirty miles and hour?! Holy crap…"

"Yes, a rather impressive speed to be sure and a full fifty miles per hour difference from running speed." Ikari smiled bright, clapping his hands together. "In fact to my knowledge, I believe the only known pro who is faster than that is All Might as he has claimed to have broken past the sound barrier before. I'm not sure I believe him, but if he tells the truth then being only behind the number one pro is a far cry from terrible in terms of speed."

With that Ikari turned to the two strength tests he had prepared while Izuku and All Might shared bemused looks behind his back.

"Now, I have just three last tests I want to go through, though only two concerning your physical body. We'll get to those in a moment however, first I wish to inspect your hammer now."

Tilting his head to the side, Izuku hurried over to said weapon and brought it back to the man. He tried to hand it over but as soon as he let go, ikari fell straight forward as the hammer crashed into the ground with a resounding thud.

"Oh my god, are you okay?!" The greenette asked worried, quickly helping the doctor back onto his feet as guilty crept through him.

"I'm fine… it seems that hammer weighs much more than it appear and far more than I could hope to lift." Ikari said, shaking his head before turning his attention to his office. "I'll be right back. In the meantime, the machine on the table is a special grip strength machine designed to withstand people with super strength and the bigger machine when you hit it will display how many newton's of force you have output onto it! Please check those while I go grab another machine I think we'll need."

"Do you need help-"

"I'll be fine thanks!"

With that, Ikari disappeared, leaving Izuku and Toshinori on their own. With a shrug, Izuku walked over to the table and picked up the small device. He gripped the top hard, watching the numbers shot up until they reached the ceiling from his grip (Which managed to put a few small cracks into the device but only very minute ones)

"Three thousand two hundred and forty eight kilograms." He read out to his mentor, who just shook his head in quiet disbelief at what he was seeing. The greenette then put it down, turning his attention to the 'punch machine' as he mentally dubbed it. He looked to All Might for confirmation he was ready, getting a nod and he threw his most powerful strike right onto the pressure pad.

The metal cracked as a number flashed up in red LED's on the screen.

"Four hundred and sixty four thousand?!" Izuku asked in disbelief, stunned at his own showing,

"Ah, that's what you managed to output? Very impressive, Midoriya! The average amount of newton's in the punch from an adult male is about one thousand five hundred in this day and age so that's quite the increase." Ikari practically gushed as he suddenly reappeared while struggling to pull along some kind of mini crane machine. "If that is your punching strength then you truly are something else."

"Uh… Doctor? What is that?!" Izuku asked in bewilderment at the machine, hurrying over and helping the man move it much easier towards the hammer that was sitting upside down and waiting.

"Ah, this is a device we use for certain quirks that increase the weight of items or have similar effects as that. You see, it may not look it but this machine is designed to be able to pick up a skyscraper. It's got internal bits of tech making it so much more powerful."

"Awesome." Izuku smiled, unable to help himself before he took a step back and watched the doctor operate it, trying to pick up the hammer.

"I'm curious to see if this is a case of the hammer being to heavy for a regular human to lift of if it's something else-" Before the doctor could even finish, a loud snap reverberated in the air as the metal claws of the 'crane' shattered trying to pick up the hammer. "-Ok so something else then."

"He who be worthy?" All Might asked in amusement, only to get a serious look from the Doctor. "No… no way? You're pulling my leg."

"Midoriya? How hard is it for you to lift the hammer?" The golden eyed doctor asked, ignoring the blonde for a moment. The greenette just shrugged, walking over and lifting it high above his head with one hand.

"Pretty easy to be honest, no heavier than a normal small hammer." He explained, setting it back down while Ikari hurried over to the display again and began to take notes.

"Interesting, then I wonder if- What the?" Suddenly, the Doctor dropped his notes as his eyes widened and he leaned in closer, before a horrified expression took over his face. "Ah! Mister Midoriya-"

Then, out of nowhere….

"AHHHHHHHH!"

A sharp searing pain shot through Izuku, causing him to let out a pained scream as he fell to his knees, clutching his head as his body began to convulse.

"Young Midoriya!"

All Might quickly rushed to his students side with panicked eyes, reaching out to him. He grabbed his hand, squeezing it tight in the only move he could think of to try to reassure the boy

"Those light rays! They stopped being inactive, they're all trying to fight for control in his body!" The doctor explained, dropping down on the other side, laying the greenette out flat. "Mister Midoriya! Focus on my voice, you need to try to bring those colliding energies within you under control."

"A-Ah ow ow wo! H-How- AHH!" Izuku's breathing was rapid and shallow, his eyes full of pain and fear as his body shuddered violently, the pain inside him like a torrent that refused to let up.

"Just try! Focus on the energy inside and bring it under your control, if you can!"

It made no sense and he still had no idea what he was actually doing but he did his best to follow the man's instructions through the pain, eventually finding a warmth inside himself and making it grow colder, before repeating the process twice over.

As he did, the shuddering began to subside, the pain disappeared and he was left taking deep, pained breathes as he recovered.

"Izuku?" All Might asked worriedly, his student just giving a shaky thumbs up as he pushed himself up off the ground, being gently held back by his mentor. "Steady now…"

"Wh-What was that?" He asked confused, Making Ikari sigh as he pointed the display towards them, showing that all three light rays were now moving and active, the green one smaller than before.

"It would appear that the inactivity of the two other rays wasn't to be permanent, they just shot to life moments before you collapsed trying to overpower one another and the dominate light ray."

"Overpower?"

"Yes. They didn't merge in anyway or leave each other alone which presumably would have ended up with more favourable results in either scenario. The green light ray took dominance initially due to its strength but the other light rays are trying to take other, and they will likely keep trying until they succeed or are destroyed. They're working against one another and as a side effect your body was being tore apart. Mister Midoriya…. We need to either make these rays combine or we need to remove them as soon as possible."

"W-What? Why?!"

Ikari fixed him with a heavy gaze.

"If we don't this process will repeat. You might be able to stave it off for a while, but unless a solution is found, as long as they stay in you…

"You are going to die."
