Izuku groaned as his eyes fluttered open, his head feeling like it might split open at any moment. He took in his surroundings before his eyes went wide and confused at what he saw.

He had expected to wake up either on the couch in his living room or in his bed, but instead he looked around to see pure white walls and a tiled roof.

"Ah, it seems your son has finally awoken." A voice spoke up and Midoriya pushed himself up slowly, seeing his mother looking at him worried with a grey haired doctor at her side. "Careful now, don't push yourself to hard. I'm Doctor Washi."

"What…. What happened?" he asked, gripping his head as he adjusted himself. "Last thing I remember we were at the market-"

His eyes widened.

"The villain! What happened with the villain?!"

"Ah, don't worry about that kid." The doctor spoke up again. "He's already been put away and probably isn't going to be causing more trouble any time soon, thanks to you."

"To me?"

"Tell me, what is the last thing you remember?"

"Uh…" He let out a small noise of exertion, scrunching up his face as he tried to remember the events. He turned his gaze to his mother, frowning. "I think… you were taken hostage, mom?"

"I was…" She confirmed quietly, tilting her head as she looked at him. Her face was pure white.

"Mom? What's the matter? You look like you've seen a ghost." The greenette asked, concerned by her subdued nature. Considering the situation they'd been in he would of thought she would have been more… active in her worry. "Did-"

Suddenly, he remembered the raw of feeling of power coursing through him in the following moments and his eyes widened, the following couple of moments a haze.

"Technically, she has." The doctor spoke up again, pulling Izuku's attention to him. "Judging by your look, you remember now what happened yes?"

"Uh… yeah? But… that isn't right. I'm quirkless. I always have been." Midoriya muttered, looking at his hand. "Maybe another pro-"

"Ah, you think someone else granted you some kind of temporary power? A cute theory but inaccurate."

"H-huh?"

"You've been here for a two days now, Izuku." The medical professional revealed, causing the apparently not-quirkless boy's eyes to widen again. "Your mother called an ambulance immediately following your collapse in your house. From there, we determined it was merely exhaustion from your quirk's first ever activation knocking you out, your body having never had to handle it before."

"M-my quirk?! You mean I actually have one!?" Izuku asked, mouth curling into a massive smile. It dropped a moment later however. "But… I was told I had the pinky joint and everything. And that was nothing like my parent's quirk…"

"All valid concerns, of course. Your mother explained as much to us when you were brought in." Washi waved as he picked up a nearby clipboard and began to read off it quietly, before turning his gaze back to the greenette. His face was serious, and his eyes conveyed quickly that Izuku needed to listen to what was about to be said. "We of course had to do some tests to confirm it, and we discovered something very interesting. You do bear all the signs of someone quirkless."

"So…. Wait, then I don't have a quirk?"

"That is what one would assume, if they hadn't seen you clearly use some superhuman abilities. So I took it upon myself as a quirk doctor to research for any known quirks that left the body unaltered for any reason, if any at all. Any signs of powerful quirks that would still leave its user mistaken for being quirkless easily." The doctor handed Izuku the clipboard, with a heavy sigh. "I had to spend my entire last two days researching through old quirk registries and such, dating all the way back to the genesis of quirks but I managed to find exactly two records of a quirk exceptionally similar to the one you have described."

'The genesis, that far back?! What is this power?'

As he thought that, he looked down at the clipboard and saw it had already been named. "Quirk: ….Super State?"

"Yes. Honestly, the biggest hurdle in finding similar quirks was how your mother described it activating. A quirk that forced the very heavens to bend to its cry for power, sounds like something out of a fantasy tale yet that's what happened with the weather on that day." Washi said, scratching his neck. "The two people who previously possessed this quirk were also thought to be quirkless. One of them, a woman from near the dawn of quirks as I said, has barely any documentation on her. It seemed anti-quirk rallies had her fleeing even with the unrivalled level of power she possessed. After her came a villain, who was barely stopped by a combination of skilled pro's using more technical quirks against his raw power."

"But, wouldn't we know if they were related to me?" Izuku asked, confused and the doctor let out a dry, humourless chuckle.

"No, because they aren't. This quirk is quite the phenomenon, one that due to the previous users being as they were, we could barely get any information on. None of the three of you likely have any blood relation at all. This is not a quirk that passes down through biology. I'm not sure what exactly is required for one to possess it, though it would appear an emotional trigger was required for the initial transformation."

"…." Izuku felt like his entire world was shattering around him. Everything he thought he knew collapsing away into nothing. A part of him tried to laugh it off as ridiculous but he simply couldn't, he had felt that power and it was…. It was far too real. "If… if you can't tell me a lot about it, what CAN you tell me?"

"Just some of the basics we picked up by cross-referencing the previous two users." The doctor sighed, tapping the clipboard and pulling over the page, revealing a series of stats. "Appearance wise, the user's eyes turn blue and the hair shines with a golden yellow glow, spiking up for reasons unknown. Your muscles swell and expand providing you with a more fit body to deal with the power. As for what it actually entails, it seems to be a multiplier to certain things such as your strength, speed, stamina and durability. What matters though is just how much of a multiplier it is."

"Thirty times?!" Izuku exclaimed in shock, looking at the readings down in front of him. He was good at maths and recalling something as simple as his old results on gym tests with such a power up in mind… "That's insane!"

"Actually, it's likely more." Washi said, standing up and walking towards a desk nearby, pulling out a set of instruments. "You see, the first user had a fifteen times multiplier at least, based on the few feats she was recorded to have performed. The second existed only a mere few years before All Might himself came into the picture, but if they had of been around at the same time even our number one pro may have had his hands full. He is All Might of course, so he would of won in the end more than likely but it would not be one of his easier fights."

Midoriya wondered about that, he couldn't help but feel like the doctor was lowballing the pro. Then again, he had yet to see in a more lucid state exactly how good the power up was so he could refrain from judging until later.

He walked over to the greenette, holding out a grip strength machine. Izuku took it, confused and the man just nodded at the teen so he gripped as tight as he could.

'27.65 Kilograms'

"Oh dear, that is a troublingly low number for someone of your age," The doctor frowned, before looking over the greenette. "Though, maybe that's part of why the quirk ended up with you? Something to keep in mind for later I suppose. Now, me and your mother are going to take a step back ok, all I want you to do is try to access that power you did in the market again."

"Huh? But, I don't even know how I did it then. Plus, what if the lightning thing happens again?! I don't want to break something." Izuku began to list off potential problems, only for Washi to smirk.

"Just try, kid. We can sort out the kinks later, just try and focus on the emotions or energy you were feeling at the time, ok?"

With a sigh, he nodded. The doctor and his mother both backed far away from him to be safe, the latter of them with a rather concerned look upon her face.

Izuku held his fists out with is arms twisted around, bent so his forearms were pushing forward while his upper arms were straight at his side, in a pose that just felt natural as he took a quick breath and focused.

After a moment, his eyes snapped open as a felt a burning sensation from deep within his being and like an inferno it spiralled out throughout his form, hair lifting up and shining with a brilliant golden glow, eyes twinkling as their colours shifted.

His arms bulked out and though he wasn't aware of it, his facial features became somewhat harsher as a frown settled onto his face. He looked too his hands, in shock. "This is…. Holy crap…."

"How do you feel, mister Midoriya?" Washi questioned, and the now blonde teen looked up to him with a contemplative look. "Powerful?"

"Well… yeah but also… Angry?" He questioned, confused over the negative feeling hidden just beneath the surface. It wasn't as present as it was before, and for Izuku who rarely felt anger in the first place it took a moment to identify but it was most definitely there. "It's like there's as much anger ready to be unleashed as there is power…"

"Well that would fit in with the supposed emotional state you were required to be in to use it. If I were a betting man, I'd imagine the real problem would arise in situations where you will need to actively tame that anger, like with the villain in the market."

Midoriya's eyes widened once more in realization.

"Wait, if I punched him full force like this… Oh god…"

"Do not worry, it seems though barely, a part of you was conscious enough to restrain your power enough to avoid killing him. However, it will be a few months before he will be released to a prison from the… injury he sustained." The doctor said, and for some reason even though normally that news would horrify the teen, right now it just left him with a mild feeling of satisfaction masking over the concern. Like his emotions were conflicting, and as they did he felt his power die down a bit. "I'd recommend we hurry up with the tests to be safe, it seems your body is handling it well enough now but you still only just received this power. You will likely need some getting used to it before you can safely use it for any extended period of time. Try the grip strength machine again, please?"

"Right." Midoriya nodded, grabbing the device and squeezing as hard as his now much muscular hands would allow. He felt the pressure put onto the machine, cracks coming into the plastic and couldn't help the small triumphant smirk at the result that flashed up on screen.

'1382.50 Kilograms!'

"Oh my…" Washi muttered, coming closer to the device with a shocked look. "A fifty times increase? That is a terrifying power boost, even with a weaker than average body like yours as the base…"

Midoriya frowned at that, as his grip on the device loosened. It quickly dissipated though as he considered the implications of that, if it applied across the board.

Normally he would feel overjoyed at the prospect of just having a quirk, but while his brain was somewhat affected by the power, the words that escaped him surprised him.

"HA! Suck it, Kacchan!" he said before he could stop himself, earning a glare from his mother who finally spoke up for the first time.

"Izuku, I never taught you to speak like that! Though give the situation, yes… yes he can." The woman said, quickly relenting before letting out a sigh.

"Mom?"

"I'm proud of you sweetie. I am but… I have no idea what to think right now." She said, sitting down again and massing her forehead. "I've been trying to think of anything to say this whole time and I just… I don't know what to think. I'm happy for you, I'm scared for you and I'm just… just confused."

"Scared?" Midoriya asked in confusion, failing to notice his super state dropping away as his hair turned back to normal, the anger he had hidden inside dissipating as it was overpowered by other emotions.

"She isn't wrong to be. This is still a quirk, Midoriya and as such it still follows similar rules to most other quirks. Like the fact that, if you train it, it's only going to get more powerful." Washi said simply. "I was trying to think how to bring this up gently but I might as well just say it outright now, your quirk could put you in serious danger if you attracted the wrong kind of attention."

"O-oh…" 'Of course…. I finally get my quirk and of course there is a caveat!'

"I'm not saying you can't use it at all, but simply pick who you use it in front of wisely while training. On the bright side however, you do get some special treatment because of your situation." The doctor said, pulling out a letter from nearby. Izuku raised his brow while the man handed it to Inko. "This is a documentation that confirms how recent the development of your powers has been, and just how powerful they are. Keep this on you and you will be able to hand them to any pro, and get away with a reasonable level of public quirk use, as well as be allowed to use it in certain gym lessons. That doesn't mean beating people in normal competitions or such of course, but if for example you decided to get some basic training in at the local park, no one could get you in trouble for utilizing your super state. At least, not for the next ten months."

"Ten months?" Izuku questioned, confused by the oddly specific amount of time. Washi fixed him with a small smile and a laugh.

"Well normally it's six months but I decided to get it extended. I said It was on the grounds of the power of your quirk but to be honest with you, off the record… I heard your mother mention you were hoping to get into U.A." the grey haired man winked. "I mean you probably already stood a chance of getting in, and maybe I shouldn't be helping anyone get a random advantage but way I see it, much better your power is on the side of the good guys than the bad guys. A little engineering to make that happen won't hurt."

"…Thank you!" The greenette exclaimed with a deep bow, making the doctor chuckle. "It means so much to me!"

"Hey, no worries kid. Now come on, let's get you back into your super state. I have a few more tests I want to try…"

Midoriya blinked, looking down at his once again scrawnier form before grinning and summoning his power much faster this time, hair spiking up instantly.

'Just the sensation of the initial transformation… it's so overwhelming and amazing…'

"Try to keep in it for as long as possible. Next up, I want to test your speed…"

It was a Tuesday when Izuku finally returned to school, heading straight out into the courtyard. Their first period of the day was gym class, and they were usually expected to just meet on the field instead of the classroom.

He was the last in, with a late pass supplied to him due to the fact he had been in the hospital. Doctor Washi had wanted to keep him one more day to be safe, asking the teen to just try to retain his super state as long as possible.

So far the record had been fifteen minutes before the anger died out and the form followed with, and the one time he had retained the anger throughout he'd managed to reach an hour before his body eventually needed to take a rest. He didn't pass out this time though, so that was a plus and according to the doctor, he'd only get better with time.

It was a bit annoying to find out he couldn't turn it off as easily as he could turn it on though. Mainly because it required him to calm down and once you were actually trying to, it gotten surprisingly more difficult to actually manage to calm oneself.

At least, that was his experience.

So it was with that thought that a huge smile came onto his face, unable to be removed even at the glares he received from students and staff alike. After all, he knew something they didn't.

Inevitably, he would be called a quirkless. useless freak by someone. It was just what happened, but now it would have zero effect on him at all because he knew it wouldn't be true.

He slipped into the changing room, quickly throwing on a white shirt and blue shorts, before putting on the exact same red shoes he always wore. With that, he did a few quick stretches, actually somewhat excited to attend class for once and quickly grabbed a familiar set of papers on his way out.

If the doctor was right, gym class was going to be his best friend and worst enemy in the coming months.

He jogged through the halls at leisurely pace, pushing the door to the back of the school and walking out into the open field. He saw his class in the distance and made his way over at a decent pace.

Excited to begin or not, he wasn't exactly wanting to talk with Kacchan sooner than he realistically had to.

"Hey look who showed up." Someone sneered, and all eyes turned to him. "Finally get out of hospital, Deku?"

"Oh god dammit, I was hoping he'd still be injured or whatever." One of the girls complained, and the greenette struggled not to roll his eyes at them. 'Thanks, I was concerned about you all as well. Oh no, wait…'

"Should of stayed in that fucking hospital, shitty Deku." Kacchan growled from nearby. "Just going to make yourself like a fucking idiot here anyways. We all know you're weak as shit."

Izuku frowned for a moment.

Washi's words ringed in his ears. Sensible words about being careful about who he showed his power off to. To be responsible.

And Izuku liked to think he was responsible. For the most part, but he'd endured years of taunts and jeers and attacks for his perceived quirklessness. Someone like Kacchan would find out eventually anyways as well so why not kill two birds with one stone.

Get the reveal out the way, and finally put an end to the biggest piece of ammunition his classmates had against him for years.

"I don't know Kacchan, I think you'd be surprised." He challenged, actually smirking. The blonde gave him a glare, setting off sparks in his hand as a threat.

This time though, Izuku stood his ground.

"Midoriya? Oh good then we're all here." Their teacher called, garnering their attention to his bored looking face. Before they lesson could get started though, the greenette hurried over to him and presented the papers wordlessly.

That certainly got the other students attention, and the few who didn't react certainly did at their teacher's sudden shout of surprise once he finished reading, face pale.

"W-WHAT?! Is… is this for real!?" He asked, looking down to his student who just nodded.

"I can prove It if need be? I think it's important everyone is kept up to date on this kind of thing." Izuku said, all to innocently as the man nodded dumbly. "Great, then can I get everyone's attention for just five minutes? I'll make this as quick as possible."

"What makes you think any of us want to listen to you?" One of the testier girls snarled, and Izuku smirked as he met her gaze head on.

"Oh, I mean I understand the feeling. Talking to any of you isn't my idea of a good time either to be honest." He said, feeling more confident than normal. He wasn't one to insult other people… but several years of their bullying meant he didn't feel too bad about the occasional small bit of retribution he could throw in. they all were caught off-guard by that, most looking to their teacher like they expected him to reprimand the greenette, as it was often the case the teacher would side against him most of the time but the man just watched on, warily. "So, let's keep this short and simple. Takashi!"

A boy on the larger side, with rock like features on his body seemed surprised to be called out, pointing to himself as if to confirm he'd just been called on.

"Yeah, your quirk didn't activate until you were five right?"

"Uh, right." He nodded dumbly, and a certain explosive blonde let out a small set of sparks in irritation.

"Get to the fucking point already, Deku?! OR DO YOU WANT ME TO BLAST YOUR ASS TO KINGDOM COME?!"

"Yeah, how about no?" Izuku asked simply, causing many eyes to go wide in shock as Bakugou seethed with anger, momentarily stunned by the greenette's bravery. "Look, his quirk didn't activate because he needed the right emotional trigger. Turns out… mine was similar."

If people hadn't seemed shocked before, now they definitely were.

"Wh- BULLSHIT!"

"It's true. I don't get angry easily, unlike someone-"

"FUCK YOU!"

"-So considering what my quirk needed to activate… No wonder it took so long."

He smirked, lifting his arms up and opening his eyes, revealing they had turned teal.

"But maybe it's better I just show you all."

he took a deep breath…. And he let loose, an explosion of golden light blinding everyone before they turned back to see Izuku in his super state, far more smug than they had ever seen them.

"It's called a super state." He began to explain, looking over himself as the others all seemed to have their brains melt due to the sheer shock. "A transformation type, gives me a pretty strong boost to various different attributes like my speed and-"

He didn't finish, as his head snapped up seeing Bakugou running straight at him.

"DEKU!"

'Predictable reaction, much?'

"Kacchan, I really wouldn't!" He tried to warn, but the natural blonde wasn't to be deterred, blasts firing off as he came straight at Izuku, aiming a punch straight for the once quirkless boy's face.

It landed clean on izuku's nose and had he been in his normal state it surely would have broken it.

Instead however, a moment of quiet silence passed as Izuku just looked annoyed and Bakugou… he stumbled back clutching his hand with a pained yell. "AHHHH! WHAT THE FUCK!?"

"I did try to warn you." Izuku said simply with a sigh. He wasn't going to calm down quickly on his own now, but he still was in control so he decided to just run with this, moving fast enough to disappear from everyone's sight and reappear beside them all, causing many to back away. "I'm just going to wait on this dying down. Someone else should probably get Kacchan to the infirmary… I'd do it but…. I'd probably break something else by accident."

He knew eventually the natural blonde was going to come back, looking for a fight at some point and more pissed off than ever. He'd probably feel guilty when he went back to his normal state but for now…

For now, he'd finally gotten a win against Bakugou for the first time in over a decade and that was a too good a feeling not to enjoy.

Word spread quickly following the incident and many who used to go out their ways to attack him kept their distance for once.

he wasn't bothered by anyone at all for the rest of the day.

IMPORTANT A/N: Ok, so i do not like putting these in fanfics on this site because this is the only way to do it and it just feels like it breaks the flow of the story but i meant to address something last chapter and forgot, and with some of the reviews i want to get it out the way as soon as possible. Izuku's quirk is scarily similar to Super Sayian but.

Izuku is not a sayian. I want to clear that up now. That's why this isn't tagged as a DBZ crossover, I just wanted to clear that misconception up while we were still early on in this.
