About 2 weeks ago, Midoriya Izuku got brain damage after taking a nasty blow from The Hero Killer.

His motor and language capabilities weren't damaged, nor his semantic and procedural memories.

But what he lost were his episodic memories.

He lost everything that made him Midoriya Izuku.

He couldn't recognise his own girlfriend, nor the little girl he lived with.

But he could recognise this angry blonde.

But he while his mind couldn't remember, his heart and body did.

His heart could recall the warmth and comfort of spending time with cute little Eri.

And his body was screaming at him to run away from this boy right in front of him.

Every nerve, every instinct, the very core of his body was telling him that this boy was dangerous.

It was as if the previous Midoriya Izuku was physically pulling him away.

"You gonna talk or what!?"

"What did you do to her?"

"Huh?"

"What the fuck did you do to Ochako!?"

But Midoriya Izuku had to stand his ground.

Because this boy was the one who hurt Ochako so.

So Midoriya Izuku had to face him no matter how dangerous he was.

No matter how scared the previous Midoriya Izuku was.

"What the fuck? Since when did you have the balls to talk to me like that!?"

"Shut up!"

"Eh?"

"I don't give a fuck about whatever nonsense you're spilling right now! But if you think I'll stand by and watch you hurt her…"

Izuku raised his clenched fist.

"Then I'll fight you!"

"HahahahaHAHAHAHAHA!" The boy started to cackle manically.

"You're really serious aren't you? Beating half and half must have gone to your fucking head. But if you think I'm half assed as that daddy's boy you're in for a fuckening."

Small explosions started crackling in his hands.

"…Of course I don't think I can beat you."

"Huh?"

"When have I ever said that? Just look at the stats you're in the UA hero course and I'm just a quirkless idiot who failed the entrance exam."

Izuku clenched his fist.

"But you hurt Ochako, you piece of shit!" Izuku pointed at her soot covered body.

He raised his fists, ready to fight.

"Give whatever fucking excuse you have! But no matter what damned reason you have, I won't just stand by and let you hurt her anymore!"

The blonde grit his teeth.

"Still fucking trying to play the hero, huh Deku?"

*BLAM*

He punched an explosion into his palm.

"If I couldn't drill it into your dense head after all these fucking years, then I'll just show you how it's impossible…"

The boy gave him an almost psychotic grin.

"I'll fucking blow you to bits! You can't be a fucking hero if you're dead! This is Bakugou Katsuki's final lesson on reality, you useless dipshit!"

The moment Izuku heard that crackle, his body instinctually ducked aside.

*BOOM*

Successfully dodging the fiery explosion wave by a hairs breadth.

'Crap, I have to move this battle away from Ochako!'

"We aren't kids playing heroes and villains at the playground anymore Deku! In a real hero fight…"

*BOOM*

Bakugou rocketed forward, aiming two explosions behind him like thrusters.

"PEOPLE CAN DIE!"

Bakugou closed the distance in an instant, and released a megaton explosion from his right palm.

*BOOM*

Which Izuku successfully diverted away with his left palm.

*SMASH*

Before delivering a right hook of his own.

"Gah! You piece of shit!"

Before Bakugou could react, Izuku successfully parried his arm and flipped him over with a judo toss.

But how was the amnesiac Izuku doing this?

His mind was empty, but his body knew. Every step, every attack, a jolt of anxiety would shoot through Izuku's body and it would react on instinct. His body was very accustomed to Bakugou's every move, being able to dodge and counterattack almost out of habit. Acting like a strange form of 'Precognition'.

Bakugou gained some distance on Izuku and aimed a palm through his clenched fist.

"AP SHOT: AUTO CANNON!"

A barrage of mini-explosions rained down, like a hail of fire arrows from the heavens.

Izuku bobbed and weaved, barely managing to dodge each one.

As Bakugou grew more and more frustrated the blasts grew, progressively becoming stronger and more frequent.

*BAM*

"!" One of the shots landed too close to Ochako, nearly eviscerating her.

In that instant he lost focus, and Bakugou got him.

A blast was coming straight for Izuku's face.

Bakugou grinned.

He didn't have enough time to dodge, and had no way of blocking.

The quirkless failure was finished.

Izuku had accepted that he was Bakugou's lesser, the difference in specs was clear from the start.

All that talk about him being the strongest? Beating Todoroki? Izuku had no idea where they got that idea from.

Because Izuku was weak.

He hadn't even lasted a minute against Bakugou.

So how could someone like that beat the strongest student in the hero course?

The old Midoriya's instincts where right from the very start.

So Izuku let go and accepted his fate.

*BREAK*

But once again his instincts kicked in, and his body moved on it's own.

His right hand reached out and the fiery explosion that would have burned him to a crisp, suddenly shattered and dissolved into nothingness at his touch.

Even if Izuku had given up, the previous Midoriya Izuku hadn't.

This was the will of the one crowned as the strongest in UA.

"What the fuck!? That fucking cheat again? How the fuck did you do that!?"

Izuku stared at his right hand dumbfounded, wasn't he supposed to be quirkless? The doctor had said he was so.

"That fucking cheat you used in the sports festival! Where the fuck did it come from!? Is someone out here trying to help you cheat!?"

The doctor mentioned something similar didn't he? Someone with a quirk would instinctively know how to use it, similar to an arm or a leg.

But Izuku was quirkless, so he couldn't have known how to activate this mysterious power.

But the previous Midoriya Izuku did, it was through his will that this power revealed itself.

"I don't see anyone else here besides you, me and Ochako. So believe it or not I'm not cheating."

"Then where the fuck did that power come from! You're quirkless!"

"You wouldn't believe me if I said I had no idea, but what does it matter?"

"Huh?"

"Nothing's changed hasn't it? You haven't changed, and you've seen me use this power in the sports festival. So why should it matter?"

Izuku glared at his opponent.

"Because even with this strange power of mine I couldn't get into the hero course! But you did with yours!"

Izuku aimed his right fist at him.

"So come on! You fight me with your explosions! And I'll fight you with…"

What exactly was this power? A paranormal miracle? The antithesis to superpowers? Divine intervention? No, there was only one name that felt right in Izuku's limited mind.

"I'll fight you with my Imagine Breaker!"

"Tch."

Bakugou blew himself into the air and continued his barrage.

"AP MACHINE-GUN!"

A barrage of larger explosive shots poured down from Bakugou's palms.

*BREAK*

Using this new power to his advantage, Izuku managed to slowly manoeuvre through the blasts.

Switching strategies Bakugou let loose the full force of his quirk.

"AP SHOT!"

A large wave of explosive energy enveloped Izuku entirely.

*BREAK*

But he only had to raise his hand to negate it.

*BOOM*

Leaving him open to the attack from the side.

Knocked off balance, Bakugou grabbed Izuku by the face clearly intending to finish this off.

Izuku struggled, grabbing Bakugou by his arm and pulling him away.

But Bakugou fell forward, suddenly losing all feeling in his quirk.

"What the?"

Sensing an opportunity, Izuku kicked Bakugou off him. Following up with a solid right hook to his face.

*SMASH*

It was clear Bakugou couldn't use his quirk when Izuku's right hand came into contact with him. So Izuku wailed on him as he struggled to regain control. Blow after blow after blow came raining down on Bakugou's face.

But because Izuku could only attack from the right, his moves became predictable.

*Grab*

So Bakugou gave Izuku a solid kick to his left, tipping him over and ending his attack barrage.

With his quirk back Bakugou attempted to follow up with a large explosion.

But Izuku grabbed Bakugou by the shin, negating his quirk once more.

Naturally Bakugou attempted to kick Izuku in the face using his remaining leg, but that was what Izuku had been waiting for.

Once Bakugou's foot left the ground Izuku pulled as hard as he could, causing Bakugou to fall over as well and crash into the ground headfirst.

Using this window of opportunity, Izuku grabbed Bakugou and started wailing on him once more.

*SMASH*

Punching Bakugou's face.

*SMASH*

Until it was bruised and bloodied.

*SMASH*

Until he was almost unrecognisable.

*SMASH*

Just like how he punched Izuku when they were little.

*SMASH*

Just like how he used to hold Izuku down and beat him.

*SMASH*

But he didn't have his lackeys to back him up this time.

*SMASH*

He didn't have his powerful quirk to attack him this time.

*SMASH*

And Izuku didn't have any explosions, just his weak quirkless fist sinking deep into Bakugou's face.

*SMASH*

And-

Izuku stared at the bloodied blonde.

He stared at his broken face.

He stared at the boy he grew up with.

He stared at the boy who used to be his best friend.

He stared at Kacchan.

He could remember him.

He could remember how they met, that their mothers were close friends.

He could remember the long summer days they played together by the stream at the forest.

He could remember how he looked up to him, how it always seemed like Kacchan could do anything and everything. While he was stuck being clumsy, useless, unlucky Izuku.

He could remember the person who gave him the name 'Deku'.

He could remember when his oldest friend laughed at him for being unlucky enough to be born without a quirk.

He could remember when his best friend beat him up for trying to defend that kid he was bullying.

He could remember when the person who he looked up to asked him to kill himself so that he could be born with a quirk in the next life.

And he remembered Midoriya Izuku almost jumping off a building that day after the entrance exam.

But he was too unlucky to even die.

"ARGGGHAAAAAAAAHHHHH!"

*BOOM*

Izuku's thoughts were broken by Kacchan forcing his way out of Izuku's hold.

Kacchan took a moment to pant and breathe, while Izuku recollected his thoughts.

Kacchan wiped the blood off his face, staring at his crimson palms and clenched them.

"Hah-" He broke into a grin.

"-HAHAHAHAHAHAHAHAHA!" Kacchan started to laugh almost maniacally.

"YOU'RE DEAD! YOU'RE FUCKING DEAD, DEKU!"

*BOOM*

Kacchan blew himself in the air once again.

"THERE WON'T BE ENOUGH OF YOU TO WIPE OFF THE GROUND ONCE I'M FUCKING DONE WITH YOU!"

*BOOM BOOM BOOM*

Kacchan made a series of explosions to propel himself in a spinning motion, creating a tornado of pure force and motion.

*BOOM BOOM BOOM*

The twister made it's way toward Izuku, the collected funnel of oxygen waiting to blow like a ticking time bomb.

*BOOM BOOM BOOM*

A bomb made from Bakugou Katsuki's pure rage and hatred.

"HOWITZER-"

The whole gym went white…

*BOOOOOOOOOOOOOOOOOOOM*

"IMPACT!"

And Bakugou Katsuki exploded like a supernova of pent up aggression, feeling his right arm tear itself apart from the force of that explosion.

As he panted from the force of his ultimate move, he struggled to breathe as he could see nothing but smoke. The explosion almost wiping all the oxygen out of the enclosed area, and blowing a giant crater in the ground.

*SMASH*

And from that smoke Midoriya Izuku appeared, seemingly unharmed from the force of Kacchan's attack.

He had run over to defend Ochako from the blast, leaving an oddly shaped path protected by his Imagine Breaker.

He returned to finish an exhausted Katsuki off with one last punch to the face, forcing him down as his head bounced off the ground with a resounding *Crack*.

The battle was over.

Izuku collapsed to the ground, and took a moment to catch his breath.

The impossible had been achieved.

For the first time in their lives, Midoriya Izuku had beaten Bakugou Katsuki.

"Here sensei!"

"Huh?"

*TWIP*

Izuku was suddenly wrapped up by a strange almost metallic cloth.

"Ugha?" Izuku mumbled through the sheets.

*Sigh* "Of course it's you problem child…" A scruffy homeless looking man grumbled.

"Umua?"

"Oh damn! Midori-bro really did a number on you Bakubro!" The red head that lead the man to Izuku was checking over Kacchan.

"Ummaaguauaua!" Izuku pointed over to Ochako's unconscious body.

But the man simply looked over and gave a tired sigh. "So that's your excuse for interfering with this training session?"

"Uwa?" A very muffled, 'wait what?' came out.

*Sigh* "Forget it, I'll just let Midnight handle you."

Midnight? Wait, his Academic Mentor? The one that already doesn't like him!?

"Kirishima! Get the med bots over and bring those two to see Recovery Girl! I'm just going to make a quick delivery…"

"Fmmmkmmmdaaaa!" Such Misfortune!
