As the fires raged in downtown Hosu, and as monsters known as Nomu attacked hero and civilian alike, Izuku was left facing a far more dangerous foe. The Hero Killer, Stain, known for his crimes against several pros in his crusade against the fakes that plagued the hero society.

As the two stared one another down, two things happened. Stain's eyes narrowed, remembering this new child from a picture Shigaraki had shown him back at the Leagues hideout. He was told the child was cunning and dangerous, and that he was not to be underestimated.

What other thing happened; you may ask?

Izuku's head started to hurt as his mind began to thump, and something told him this was no headache. In his mind he could hear arguing, yet the voices never reached him. They would faint, yet he could sense the hostility in every word being spoken. The previous users of OFA…were they fighting?

That didn't matter now. What mattered was protecting Iida and Native, no matter the cost.

"Get up and run Iida, I'll grab Native and be right behind you." Izuku whispered down to his friend.

"I-I can't." Iida informed, struggling to move. "E-Ever since he cut me, I-I've been unable to move. I think it's his quirk." He said, causing Izuku to growl.

From watching the news and reading articles, he had theorized Stains weapons were connected to his quirk. But how exactly were they? Was it just a simple cut that paralyzed his foes? Or, did he have to do something with the blood from the cuts? While Izuku didn't know the exact cause for this paralyzation, he did know this. Avoid his weapons at all cost.

"Midoriya please…don't get involved." Iida pleaded, breaking Izuku out of his thoughts. He cast a side glance towards his friend, facial expression showing he was shocked and confused. "This-This doesn't have anything to do with you!"

"Iida…what are you talking about?"

"You showed up to save your friends life, that's commendable, I'll give you that." Stain spoke, causing Izuku to turn his attention from his friend to his foe. "But I have a duty to kill him and this so called 'pro'. When your friend chose to fight me, it guaranteed the weaker of us would be culled."

Izuku fought a shiver from Stains words and his tone. The villain was serious and was leaving no room for argument or negotiation. The guy truly believed it was his sacred duty to cut down those he deemed unworthy to call themselves a hero.

"So, what will you do?"

Izuku gritted his teeth, managing to shoot off a quick text to the 1A group chat in hopes that someone close by would get it and be able to help. He realized he should've grabbed a pro to come and help, or perhaps Agent Hill could've sparred a few more SHIELD agents.

Izuku moved to the left, now using his body to fully protect Iida as he raised his shield to his chest. He had to protect them until someone came to help, and if he was lucky, maybe he could defeat Stain in the process, or even scare him off and make him retreat.

"Listen to me! Stand down and run away, I told you this has nothing to do with you!" Iida ordered, not wanting Izuku in this fight. This was his battle, he needed to avenge Tensei!

"If you truly believe that, then why are you trying to be a hero in the first place?" Izuku snapped at him, causing Iida's eyes to widen in surprise. "To be a hero is to give help when it's not asked for, to protect those who cannot protect themselves, even if it costs you your life. All Might said that's the essence of being a hero!"

As the greenette moved into a fighting stance, ready for whatever Stain was about to throw at him, he wished he could say everything he wanted to. This fight had everything to do with him: Iida and Tensei, some of his close friends had gotten either injured or worse because of Stain. On top of that, what kind of hero would he be if ran away now when Iida and Native needed his help.

"I've made a vow Stain; to use this shield to protect those who cannot protect themselves. If you want them, you'll have to get through me first!"

Izuku rushed him first, causing the maniac to show off a wide and excited, borderline psychotic grin. Stain unsheathed his sword and slashed from the right to the left, but Izuku ducked underneath, and slid through the murderer's legs.

Twisting his body Izuku tossed his shield, and sent it slamming into the villains back before it flew up into the air. Stain stumbled and turned, grabbing a knife from his side before throwing it at Izuku. The greenette raised his hand, attempting to stop it with his metal powers before it could get any closer.

His eyes widened in surprise when it showed no signs in slowing down. Reaching his other arm into the air, Izuku's shield came back to him, allowing him to easily smack the knife out of the air. The smack sent it flying, and the weapon implanted itself into a brick wall.

'Why-Why couldn't I control it?' Izuku thought to himself, staring down at his hand. Was his metal quirk not working? Could it be possible that Stain had more than just one quirk?

"Sorry to burst your bubble kid, but you're not the first person I've faced with a metal controlling quirk." Stain grinned as he showed off his sword, menacing aura oozing off of him. "I've been forced to adapt since I began my crusade, and changing the material of my tools was necessary in order to survive."

"What will you do now 'hero'? The ace up your sleeve has been removed from play, so what shall you do?"

Izuku scowled in annoyance. Stain may have been a murderous scumbag, but even Izuku could admit he was smart. The villain adapted every time a new variable was added, it was one of the reasons why he escaped capture for so long.

Izuku rushed him again, activating Full Cowling to get in close so Stain couldn't hit him. Stain backed away, sword slicing through the air to the left and right, trying to cover the area in front of him to keep the greenette away.

From the left, to right, to left again Izuku dodged each swipe, not allowing the blade to get close to his skin to make contact. Hand glowing green, a trash can was sent flying behind Stain and aimed towards his feet.

Stain unsheathed another knife and plunged it into the trash can, before bringing it over his head and throwing it at Izuku. The greenette took control of the can and threw it to the side, avoiding it. The villain slashed at Izuku once more, but the attack was blocked thanks to his shield.

This continued, with the two dancing a dangerous dance as they fought. Stain continued to swipe and slash, but each attack was blocked with Izuku's shield. Stomping onto the ground with Full Cowling, Izuku launched himself towards Stain, and managed to get past his defenses.

Twisting his body, Izuku delivered a roundhouse kick to Stain's left side, sending the villain smacking into the brick wall. The greenette followed this up by jumping onto the opposite fall, and pushed himself off with Full Cowling, the momentum launching him like a torpedo with his fist reeling back. Stain saw this, before digging himself out of the wall and dodging the Detroit Smash meant for him. After Izuku's fist smashed into the wall, he followed up the attack by tossing his shield at Stain once more. The villain blocked it with his sword, causing it to launch into the air.

Stain's defense was something else, as was his reaction time. Attacks from the front wouldn't do, especially since Izuku had to be careful of those blades.

But what about attacks from behind?

Izuku activated his quirk, causing his shield to fly right back to his arm. Reeling back he launched it into one of the walls, causing it to bounce back and forth while slowly moving towards the villain. Stain saw this, and ducked underneath.

The murderer's eyes widened in surprise as Izuku launched forward, body glowing green, readying himself for another attack. Stain jumped backwards, attempting to distance himself, but felt something smash into the side of his head as he did so.

The shield was still bouncing as Izuku rushed forward to attack, which made Stain retreat backwards to avoid the greenette. This, however, caused Stain to move backwards into the shields path, allowing the shield to make contact. The hit sent the shield flying back into the air, and knocked Stain out of his senses momentarily.

Izuku jumped into the air, following and grabbing onto his shield before green lightning covered his body. Swinging down, Izuku used his shield and smashed it onto Stain's head, like a hammer to a nail, and caused the villain to crumble into the ground, the concrete breaking by the force of the hit.

The greenette landed, and turned to stare at the unmoving body of his opponent. Satisfied, he turned and began walking towards Iida, who stared at him in awe and surprise.

"We're having a long conversation when we get you to the hospital." Izuku informed, tone leaving no room for argument. Iida sighed in relief and nodded, knowing his friend was not only angry with him, but also probably incredibly disappointed.

"Understood, Midoriya."

"Midoriya! I'm here to…help." Todoroki called out after rounding the corner, ready to help his friends in need.

Imagine his surprise (and disappoint) at seeing Stain unconscious, Iida and a pro hero unmoving, and Midoriya standing victorious. How late was he?!

"Appreciate you coming Todoroki, but Stain's been taken-" Izuku began to say, before Iida screamed in pain.

He looked down, and watched as blood began pouring from his friends' hand, a new knife implanted in it. He felt something whiz past him, and looked to see as two knives fly and pierce Todoroki's left forearm.

"Look out!" Todoroki called out, ice forming and traveling on the ground and towards them. Izuku turned, and watched with wide eyes as Stain sprinted towards them, sword raised and aiming for Iida.

Iida watched, and closed his eyes fearing the force as Stain got closer. He could hear it, the sickening sound of flesh being sliced and pierced into. But, the blunette was confused when he felt no pain. Opening his eyes, they widened in horror as Stain's sword was an inch away from his face, the tip dripping blood onto the ground before him.

Whose blood was dripping from his weapon? Iida turned his view past the weapon, and his questioned was answered.

Izuku stood before him, teeth grinding together in pain, the swords blade imbedded half way through his left hand. He had panicked, and instead of using his shield, used his own hand to block the attack.

Izuku and Stain stared each other in the eye, Stain's widened in surprise and for the first time ever, fear, while Izuku's eyes held only anger. Izuku brought his left hand up, taking the blades tip further away from Iida's face.

"What did I tell you, Stain?" Izuku growled, walking with Stain as the villain began taking steps backwards. "I said I'm going to protect those who cannot protect themselves, no matter the cost." Pulling his shield back, Izuku smashed the edge into Stain's sword, breaking, snapping the blade in two.

Stain would've jumped back, to distance himself from this…from this lunatic, but felt himself unable to move. Looking down, he noticed his legs were cocooned in ice from the new child.

He was trapped.

Green lightning danced across Izuku's body, and the clothing surrounding his right army slowly began to disintegrate. Reeling back, he launched the fist forward, and made contact with Stain's chest.

A shockwave flew through the alleyway, causing trash cans and bags to get launched down and into the streets. Stain was sent flying backwards, before smashing through several walls of ice. He felt his back breaking more and more with each pass through, and knew multiple ribs had been snapped in two, maybe even three times.

Iida finally felt his mobility come back, and struggled for a bit before standing up. He stared at Midoriya, blood dripping from the hole in his hand as the half piece of blade finally fell from it. His right arm seemed to be purple and swollen from the hit.

"M-Midoriya-?"

"You still want revenge, right?" Izuku questioned, not turning back to look at his friend. His body was screaming at him for letting his emotions, yet again, get the better of him. He went above six percent, and used what felt like nine, maybe even 10.

"We-We need to get you to a hospital, Midoriya. Your arm, and hand…they need medical attention."

"After he's no longer moving." Izuku growled, turning back to stare at his friend from the corner of his eye. "You wanted this after all, didn't you?"

Iida gulped, feeling the guilt hit him all at once. Todoroki and Midoriya, especially Midoriya, had gone through unbelievable pain to save him and to stop Stain.

He wanted let their sacrifices go to waste.

"Let's finish this." He nodded, causing Izuku to nod in agreement.

Stain struggled to stand, his back and ribs injured, broken. Something had also probably been punctured as well, meaning he needed to get out of here, to escape so his crusade could continue.

Before he could escape, he heard as two sets of footsteps ran towards him. He looked to see green and blue ran at him, before feeling two separate things hit him: one in the face and the other in his side. The villain dropped after that, this time, fully and undoubtedly unconscious, as Izuku and Iida stood over him. A super powered punch and lighting quick kick was all it took to finally bring down the hero killer Stain.

"Let's find some rope to tie him up." Izuku said, causing Todoroki and Iida to nod in agreement.

It would take a few minutes, but eventually they found some rope that had fallen out of one of the trash cans Izuku had sent flying. After tying Stain up and having Iida and Native help each walk, the four made their way down the end of the alleyway, and out into the open streets.

"We need to get him to the police as fast as we can." Native informed, causing the others to nod in agreement.

"What are you doing here boy?!" A voice shouted, causing Izuku to sigh and the three to stare at him in curiosity. The next thing they knew, a yellow and white cladded old man came flying out the alleyway across from them, and kicked the greenette in the face. Izuku was sent falling flat on his ass. "I thought I told you to stay on the bullet train!" He shouted.

"Hey, it wasn't my fault! After you left another Nomu showed up and abducted me!" Izuku shouted back in defense, rubbing his chin from the kick.

"Midoriya? Who's-"

"This is Gran Torni." He sighed. "The hero I've been interning with this whole week."

"Isn't he a little…" Todoroki trailed off, trying to find the right word.

"What?! Old?! Short?!"

"I was going to say short tempered." The son of Endeavor grumbled. "But…now that you mention it."

Before GT could scream and attack Todoroki, the group could hear voices and several foot steps from around the corner. Five heroes rounded the corner, and ran to them.

After getting over their initial shock of the people Endeavor sent for them to help ending up being children, and after seeing them with a tied with hero killer, they began checking the wounds of each of them, while one called the ambulance and police to come and help.

Izuku, with his injuries, was helped to his feet, and his hand was bandaged right away. Todoroki, Native, and Iida also had their injures looked at, and patched well enough to keep any more blood from seeping out until the ambulance came.

Iida steeled his nerves, and walked up to Midoriya and Todoroki after their wounds were taken care of. He owed them an apology for what they had done and what they had gone through. They risked life and limb and were seriously injured during his quest for vengeance. He hadn't meant for all of this to happen. He was just so…so angry at Stain for what happened to Tensei. But to put his friends in harms way for such a selfish reason? Maybe Stain was right? Maybe he wasn't meant to be like Tensei, or like Midoriya.

"Hit the deck!" GT shouted, causing many to panic and stared where GT was looking at. In the sky flew a winged Nomu, and it was coming straight at them.

"Oh no." Izuku sighed, before feeling talons clutch around him once again. "Why's it always me?!" He shouted while being hauled off into the air, watching as the Nomu bled from its one eye and showered the heroes below him.

The heroes were shocked to see the greenette being flown away, and started to think of what they could do. Todoroki could his use fire, but that had the risk of burning Midoriya. GT could fly up there, but he would have to do it soon, otherwise he wouldn't be able to reach.

Running could be heard, and the female hero felt something slimy run across her cheek. They watched as the Nomu froze midair, and as a figure in a red scarf ran past them.

Stain jumped into the landed and caught up to the Nomu, before plunging his knife into the Nomu's good eye, before twisting it. The Nomu flew down and crashed into the concrete below, while letting Izuku go.

"The word 'hero' has lost all meaning in todays society. The world is overrun by fakes and criminals like you all who chase pathetic dreams!" Stain growled, slashing his knife through the Nomu's exposed brain to make sure it was fully dead. "You must all be purged."

The heroes were frozen with fear as Stain stood up above his fresh kill, a menacing and killer aura oozing off of him once more.

"Everything I do…is to create a stronger society." Stain looked passed the fakes, and growled in anger as a man covered in flames ran around the corner.

"Hero killer!" Endeavor shouted, readying an attack before GT stopped him. Izuku was still in the line of fire, and sat before Stain after being left go by the Nomu.

"Endeavor." Stain growled, turning from the Nomu to stare at the group. His mask fell, allowing his disformed face to be shown to them. They could better see the bloodlust in his red and savage eyes. "You false hero!" He said, slowly taking steps towards them.

Izuku readied his shield to protect himself, but was confused as the villain walked past him, not bothering to attack. A knife was dropped next to him, much to his confusion.

"These streets…must run with the blood of hypocrites!" He shouted, aura so menacing and, for a lack of a better term, scary, causing the group to either freeze or began to take steps back. "Hero! I will reclaim that word! C'mon! Just try and stop me you fakes! There is only one man that I will let kill me!"

"ALL MIGHT IS WORTHY!"

Klink

The fear turned to confusion, as Stain stood still, the knife covered in Nomu blood dropping to the ground. The villain fell to his knees, before falling flat on his face.

"He-He's unconscious." Endeavor informed, causing many to fall to their knees in relief.

Izuku could hear sirens in the distance, and sighed in relief. The knife next to his foot caught his attention, since he could see something inscribed on the side. He got closer to read it, and his eyes widened in surprise.

"For those worthy"
