Quirk Deku One-shots

Damage Mirror (984)

Izuku stood with many hero's. The fight was nigh, and All For One wasn't going to turn himself in. They stood in front of the warehouse as tensions rose. Mt. Lady was getting ready as they waited for the signal to start. He was stationed at the front, and not for a lack of reason.

His quirk was a worrisome one, but with a lot of knives all over his body, he could make it a pain to deal with. 

His personal healer stood by his side, ready to make sure he doesn't kill himself in an attempt to make his way known. 

The cold air drifted by as they waited. Quietly, and patiently. Hoping to surprise the villain who lived in such a dreary place.

The surroundings were nothing but black, and the dead silence hung over the hero's, ready to jump into action.

Then their radio's crackled to life, and a single beep sounded.

It was go time.

Mt. Lady grew to her impressive size, slipping one of her feet into a pick-up truck, and raising it up to the air.

"LET'S DO THIS!"

Her giant voice boomed as her foot slammed down into the warehouse, crumbling the wall, roof, and most of entrance in a plume of dust. 

Hero's rushed in to capture any of the biological weapons hidden there, but a voice beat them to it.

"Ah. Hero's. Why so loud?"

A blast of air blows out from the warehouse, throwing all the hero's out of the building, and landing on their backs.

"Was there a party I missed?"

The voice's owner slowly revealed themselves. A man tall as All Might, wearing a suit, and whose face was covered with a mask covered in tubing.

"How about I start it?"

As the villain raised his arm, Izuku's endless hours of analysis could tell the twitching muscles from far away, and knew that a quirk was coming. What quirk, he didn't know but if it existed it was something he didn't want to see.

Pulling out a knife, All For One watched in slight horror as he stabbed himself. Right in the chest, missing all organs, but after twisting the knife and gutting himself, the wound was sure to hurt.

All For One didn't have to imagine that pain though as as soon as Izuku plunged the knife in, All For One could feel a hot burning pain searing its way into his chest. As Izuku twisted it, both could feel their ligaments, blood vessels, and nerves tearing. Warm blood gushed out from both as the wound continued to rip upon itself, every twist of the knife.

Pulling it out, the healer beside Izuku quickly healed him, adding another gigantic scar to the collection that covered his body. All For One healed too, using his regeneration as it closed in a scar larger than he wanted.

Taking this chance, the downed hero's all got out of the way. Izuku had warned them what will happen if All For One had regeneration, and none of the hero's wanted to be caught in the crossfire.

All For One watched Izuku now in slight fear as Izuku smiled, taking out more knives.

"Let's play All FOr ONE!"

As Izuku's voice slowly got louder and louder, his stabbed knives into his joints, his torso. His body began to fill with knives as Izuku stared at All For One. Using goggles to limit his vision as to not down hero's.

The wounds spread across All For One as he roared in pain. Searing pain dug into his body as he could barely hold onto reason. If he tried to stop the pain, another burning stab wound appeared. Every healed wound was replaced with a new one.

Grabbing onto any reason not buried under pain, All For One began to ready his quirks, but looking at Izuku, he froze.

Izuku was pouring out blood as he continuously stabbed and carved himself open. Each and every wound being placed on All For One's body. If he stabbed his side, All For One could feel it, and the warm blood flowing out told him it was really there.

More healers had joined the fray, working overtime to heal his accumulating wounds.

The point of fear however wasn't what Izuku was doing, but what he was ready to do.

The insane eyes of Izuku were trained on him. Nothing else. He was staring without a single wince or blink of pain. One hand was still carving himself open, leaving healers to constantly try to keep him alive. The other was still. His hand held a knife poised to his head. The tip of the undoubtably sharp blade pressed against his temple. The searing pain from that area told All For One all he needed to know.

"You don't have the courage."

Bleeding and trying to hide that he was desperate, All For One tried to discourage the young hero, but the increasing pain on his temple was more than enough of a threat.

"Try me bitch."

The hero's sassy voice rang in All For One's ears, and he could hear the pure determination to see this through. Both people were wracked in pain, and both knew their healing couldn't hold up. The deal was anything but complicated.

'You turn yourself in, or I'm dying and taking you with me.'

That silent threat hung in the air for a whole 10 seconds before All For One raised his hands. He was determined, but he was still human, and therefore won't walk to his own death.

"I surrender."

Those two words doused the hero's in disbelief. If anyone ever said one young hero could bring the overlord of the underworld down to his knees, they would've laughed. They would've called them delusional. Yet here they stood. Watching as a young hero looked that same overlord in the eye, a knife about to carve open their temple, and slowly stopping his other hand from carving himself open.

Hero's slowly approached, cuffing the overlord as All For One silently obey'd.

The persisting pain in his temple was all the convincing he needed to not resist. 

The doors slowly closed on the transport, and Izuku slowly relaxed. Allowing the third healer to heal his latest wound.

"You better enjoy prison All For One."

Taking a step to help others, his ankle twists, giving some unlucky hero a twisted ankle too, and he passes out as he falls to the ground.

"Good grief."

Picking him up, Recovery Girl just lifted him to the cot she had prepared.

"How he pushes while running on fumes still worries me. How he hasn't killed himself still confuses me."

As the villain was carted away, All Might finished rescues on the other side, oblivious to the showdown that had gone down.

All's well that ends well?
