MHA : Architect Of Time [Rewrite]

[This is the first time Izuku is going to fight someone stronger than him.]

What happened? What's wrong here?I scanned the entire ground, my mind racing.No, no, no—looking around won't help. I need to see ahead. At least ten seconds into the future.

+10 SECONDS INTO THE FUTURE

Aizawa stood at the front, his sharp gaze sweeping across the area. The class murmured in excitement, oblivious. Everything seemed normal.

Then—black mist erupted in the center of the facility. A massive, swirling void of darkness twisted into existence, warping the air around it. And from that void—they stepped out. Villains. They flooded in like a swarm. First in twos and threes, then dozens. No—hundreds.

1.

At the center of the chaos, one figure stood out.A man with messy blue hair, his sickly pale skin stretched tight over his bones. His lips—dry, cracked, crumbling.

He tilted his head, scanning the area with lazy disinterest. Then he clicked his tongue. Tch."This place is a damn fortress… Where's All Might?"

2.

Beside him, a shifting, grotesque mass loomed—a creature unlike any other.

His fingers twitched. "WHERE'S ALL MIGHT?!" 

And then—chaos erupted.

3.

Aizawa rushed at the villains as soon as he could react. His capture scarf snapped forward, wrapping around the closest villain's wrist. With a sharp yank, he flipped the man onto the ground, knocking him out instantly.

But more were coming. Too many.

They surged forward, quirks activating—a wall of destruction crashing toward him.

Aizawa didn't hesitate. He ducked under a blast of fire, eyes locking onto the user. The flames vanished as their quirk was erased. He spun, twisting midair, slamming his boot into another villain's face.

Efficient. Precise. But outnumbered.

A shadow moved. Above.

A villain with a knife—diving straight for his back.

I gasped, snapping back to the present. We are f*****.

"Aiza-"

I stopped mid-sentence as the portals began opening.

Just as I had seen—black mist erupted in the center of the facility.

A massive, swirling void of darkness twisted into existence, warping the air around it.

And then—they stepped out.

Gasps. Screams. The class finally noticed.

They came in waves. First in twos and threes. Then dozens. Then hundreds.

My stomach dropped. I already saw this. But knowing didn't make it any easier.

Aizawa moved.

His scarf shot forward, wrapping around a villain's wrist. With a sharp yank—slam—the man hit the ground, out cold.

Another charged him—Aizawa spun, boot meeting their face in a brutal kick.

I had to rush, or my dear teacher will bite the dust. I rushed in.

20%. Is it gonna be enough?

Lightning crackled around me as I exploded forward, my feet tearing into the pavement. The rush of speed blurred everything—screams, villains, the chaos unfolding around me.

Aizawa flipped another villain over his shoulder, landing hard, but he didn't see the knife. The one coming from above—seconds away from plunging into his back.

Not happening.

I shot forward, the force of my movement shattering the ground beneath me. The villain barely had time to react before I slammed into him midair, my fist crashing into his ribs.

A sickening crack. He was out cold before he even hit the ground.

Aizawa turned, his sharp gaze locking onto me for just a second—an acknowledgment. But there was no time for words.

"This place is a damn fortress… Where's All Might?"

The blue-haired villain called out as the creature beside him growled.

What is that even?

It wasn't just big—it was unnatural. Muscles layered over muscles, grotesquely stitched together, like something that had no right to exist. Its exposed brain pulsed with each breath, and its glowing red eyes locked onto Aizawa like a predator spotting prey.

I felt it before it even moved.

Killer intent.

Instinctively, or for some other reason between them, and with a huge leap, I landed on the creature... It didn't even budge.

It didn't even flinch.

I crouched low, my fingers pressing into the thick, unnatural muscle beneath me.

Nothing.

My landing should have knocked it back. Hell, it should have at least staggered.

It didn't.

It wasn't just big—it was wrong.

The Nomu's head turned toward me, slow and mechanical. Like a machine identifying a target.

And then—

It ripped off my right hand.

I didn't even see it move.

For a second, I didn't register it.

My body lurched. My balance shifted. My brain knew something was wrong, but I couldn't place what.

Then—I saw it.

The jagged stump. The blood—hot, pouring, pulsing.

My stomach dropped.

Pain.

It hit all at once, like white-hot fire spreading through my nerves. A scream ripped from my throat before I could stop it.

My heartbeat roared in my ears, drowning out the chaos. My vision wavered, red at the edges.

My hand. My hand. My hand.

"DEKU!"

"MIDORIYA!"

They called out.

Focus.

I forced myself to breathe, my mind pushing past the raw fear clawing at my chest.

Reverse.

Time surged.

The blood rushing from my wrist flowed backward. Torn flesh knit together as if rewinding a scene in a movie. Bone reformed. Skin sealed.

Whole again.

The pain was gone. 

But the terror remained.

I flexed my fingers—solid, real.

But my gut twisted.

That wasn't normal.

I had faced danger before. I had been hurt before. But never—never like this.

I looked up.

The Nomu wasn't even looking at me anymore.

It had already dismissed me as a threat.

My breath hitched.

I turned—Aizawa was staring.

Not at my wound. At me.

Eyes wide. Calculating. Disbelief flickering behind them for just a second before he shoved it away.

"That's not a quirk... what the hell is that?" I heard him mutter.

I didn't want this. Not now. Not so soon.

[1-A]

Gasps. Screams.

"Did—did it just rip off his hand?!"

"Holy shit—Midoriya!"

The class was frozen. Not in fear—in horror.

They had seen injuries before. They had trained, they had fought. But this? This was different.

Ochaco's hands flew to her mouth, her eyes wide, shaking. "No… No, no, no…"

Kirishima's breath hitched. His fingers twitched like he wanted to move, to act—to do something. But he stood there, stiff, his body betraying him.

Iida's entire frame tensed, hands clenched into tight fists. "We have to help him—"

He moved forward, but something stopped him.

Bakugo.

He was staring.

His usual scowl was gone. His mouth was open, just slightly.

Not anger. Not even frustration.

Shock.

The kind that ran deeper than just surprise. The kind that rattled something in his bones.

For just a second, he didn't see Deku—the annoying nerd he had always looked down on.

He saw Izuku Midoriya.

Bleeding. Screaming. Dying.

And then—he saw something impossible.

The blood reversed. The flesh knitted. The bone reformed.

And Midoriya stood whole again.

Kirishima blinked. "What…?"

"What the hell?" Kaminari's voice cracked. "That's—not—"

"That's not normal."

I could feel their eyes on me.

Not just fear.

Doubt.

Confusion.

Suspicion.

[1st POV]

But there was no hiding it anymore.

Where... where is All Might?!

Actually, never mind, it's pointless waiting for help. I gotta kill this thing before it does anything else. 

100% O.F.A, I knew it was not gonna be enough for this guy but I have to try. "OI!" I shouted as I rushed to the Nomu. [At this point, I'm getting sick of calling him "Creature" "Thing" and "Monster", so please bear with me.]

It lurched back suddenly as it drew its fist, stop, I watched as the world came to a halt. Ten seconds and a dream, I need to make it happen. I can't die here, not with Mom waiting for me at home.

I planted my feet behind the Nomu, winding my arm back. 100% OFA coursed through me, lightning crackling, muscles screaming under the strain. I felt my bones creak, my skin tightening against the force. And with ten seconds and a dream. "SMASH! SMASH! SMASH! SMASH! SMASH! SMASH! SMASH! SMASH! SMASH! SMASH!" It's a smash for every single second.

And BOOM! The Nomu blasted off, crashing onto a nearby wall. I paused for a second as I looked at my hand... YES! 

Cracks spiderwebbed outward from the impact, concrete chunks raining down around it.

I didn't wait. I couldn't afford to.

The second my feet touched the ground, I surged forward, electricity crackling, my legs screaming from the strain of 100% OFA. My muscles burned, bones creaking under the force, but I couldn't stop. Not now. Not after what it did.

The Nomu twitched. Its grotesque limbs spasmed, jerking unnaturally as it began to stand.

"Are you serious?!" I gritted my teeth, watching in disbelief as it straightened, its broken bones snapping back into place with sickening crunches. Torn flesh regenerated, muscle knitting back together, and its empty eyes locked onto me once more.

Unfazed. Uninjured. Unstoppable.

"Regeneration…?" My heart sank, the full weight of the realization hitting me. Even 100% wasn't enough. It didn't even leave a scratch.

The Nomu's mouth opened, and a guttural growl vibrated through the air. It wasn't a sound of pain. It was annoyance.

It was getting angry.

Then it moved.

Faster than before.

Its form blurred, the air shattering as it lunged at me, its fist drawn back, ready to strike.

Stop.

The world froze. The sheer force of its movement left shockwaves rippling through the air, fragments of concrete suspended mid-flight. Its massive arm hovered mere inches from my face, the pressure alone making my skin prickle.

I had ten seconds. Ten precious seconds.

Think, damn it. I had to figure this out. It was faster. Stronger. And it could regenerate. My attacks didn't matter. Even at full power, they didn't matter.

Then what could?

My eyes darted across its form, scanning every detail. Its muscles were grotesquely overdeveloped, its body stitched together like a monster made from countless pieces. A creature designed for destruction. A weapon.

But even weapons have weaknesses.

My gaze locked onto its head—more specifically, its exposed brain, throbbing with each heartbeat. Its only vulnerability.

That had to be it. I needed to hit it. Hard. Fast. Without giving it a chance to regenerate.

I only had one shot.

Time resumed.

I ducked under its arm, the force of its punch tearing through the air above me, shattering the ground behind us. Rocks and dust exploded outward, but I was already moving.

Lightning crackled around me as I circled behind it, my vision narrowing, focusing on that one point. The brain.

My body protested, every muscle screaming in agony. But I pushed through, pushing past the pain, the fear, the doubt.

I leaped, twisting my body midair, my fist drawn back, 100% coursing through me, electricity dancing along my arm.

This was it.

The Nomu's head turned, its vacant eyes locking onto me. It moved, its body contorting at an unnatural angle, its arm swinging to intercept me.

I grinned.

Not fast enough.

"SMASH!" 

[I know it seems that no one is participating but this was in the span of a minute and half.]
