Moments Earlier, Hosu City:

A line of yellow tape blocked off a small alley where another victim of the hero killer lay. As the crowd grew, on a rooftop overlooking the scene was the man himself. Crouching on top of a water tower, he licked a splatter of blood off his jagged and worn katana blade.

"You haven't even noticed it, have you? This warped society mired by hypocrisy and vanity. That's fine, I'll open your eyes, "heroes". You will see the world that you've created." Stain watched on as the police kept people back from the scene. Sensing that he wasn't alone, he swung his blade backwards only to hit what felt like empty air. Turning his gaze, he saw a large swirl of black and blue-purple energy with two glowing yellow eyes.

"Please, remain calm. We are of the same mind. I have been searching for you, hero killer Stain. I heard of your exploits and wanted to meet you in person. I think you'll be interested in what I have to offer." At this, Stain narrowed his gaze and put his blade back in its sheath. At this, the mist swallowed Stain, and when he could see again, he was in a bar with two young men looking at him and the mist turned into a man in a vest.

Now, League of Villains Bar:

"Boys, meet the hero killer Stain." At this, Kurogiri walked over to the bar and pushed a button on the monitor, activating the channel to All for One's communications.

"Now I get it. You all attacked U.A., and you want to recruit me to help build up your little group again." Stain practically growled at them.

"Yeah, it'll be great with all the experience you have."

"... And what's your mission?" Stain glared at Tomura, who spoke up before Deku had a chance to.

"For now we just want to kill All Might. I like to destroy anything that pisses me off." Tomura stated, and Deku shook his head.

"Tomura, try to be more civil, will you?" Deku nudged his "brother" in the arm and Stain growled in anger.

"I was a fool to think you could offer me anything. Turns out, you are the type of person I hate most in this world. The goals of your "league" are those of a child. What meaning is there to killing if you don't have real convictions?" Stain grabbed two of his blades, and Kurogiri and Deku readied themselves.

"Master, should we stop this?" Deku asked the screen, and the reply came through seconds later.

"Let it happen. It's possible this is the only way he'll learn anything. He needs to think about the ways he must grow, how he can mature. Only then will he reach his potential." At this, Stain leapt forward, trying to strike at Tomura. Deku jumped behind the bar and joined Kurogiri as the hero killer and Tomura went head to head.

"I don't like this, Kurogiri. That man is a fanatic, one who seems more likely to kill us all than join us." Deku watched as Stain kept up with his swift and brutal strikes that Tomura could just barely dodge. Stain then slashed at both Kurogiri and Deku, drawing blood from them both. As he licked the blades, the two felt themselves go stiff and they tried to move to no avail. Finally, Stain pinned Tomura to the ground and then stabbed him in the shoulder.

"You want me to join you, but if you don't have conviction or desire you won't accomplish anything. Without them, you'll be nothing more than an aimless weakling that achieves nothing. That's how you got here."

"Enough out of you, knife boy. Kurogiri, take him back." Deku muttered, and Kurogiri simply groaned in pain.

"I can't, it must be his quirk."

"The word "hero" has lost all meaning in this society. It's overrun with fakes and criminals like you that chase petty dreams like fame, fortune or wanton destruction. They must all be purged." Stain moved his knife close to the hand on Tomura's face, only to see Tomura grip the blade.

"If you dare touch this palm... I'll kill you. You keep talking about conviction, "hero killer", and I may not have much of that." Tomura's quirk had cracked and rusted the knife away to dust at this point.

"But if I had to say what I want, it'd be killing All Might. If this world wants to worship him as their heroic savior, I'll end him and crush the rest of them while they're in shock." Stain jumped away as Tomura swiped out to grab him, allowing Tomura to get up.

"I see what kind of person you are. It would seem our goals oppose each other. However, we both agree the present must be changed, by destructive means."

"I'm over this. Leave, drop dead. I'm the kind of guy you hate most, remember?"

"That was to test your motives. Only on the verge of death do you see a person's true colors. There's a sprout of conviction in you, but it's warped. How will it bloom, I wonder. Maybe I'll allow it to grow, and if you don't turn out well, I'll take care of you later." At this, Deku growled and finally felt himself gain control of his body. Jumping over the bar, he created a ball of concentrated fire and aimed it at Stain as a warning.

"You're insane, a blood lust fanatic. Someone like you is going to be nothing but a problem for us. Kurogiri, take him back."

"Both of you, reconsider. This man's skills and prowess would be a great asset if he joined our ranks." At this, Stain turned to Kurogiri.

"My business here is done. I've heard you out and now you will return me to Hosu. There are several false heroes I must attend to there." The hero killer licked his lips and Kurogiri created a warp gate for him. As the last of Stain's garments had disappeared, Tomura turned and sat at the bar. Deku extinguished his fire and stood near the jukebox, while removing his now blood stained vest.

"... He wasn't entirely wrong about you." Deku stated, looking over the songs.

"... what did you just say?" Tomura practically growled at Deku, and Kurogiri stood ready to intervene.

"You focus to much on here and now. You want to do nothing more than destroy what's in your way, without thought to a greater goal. Consider the future we're creating and use that ideal to alter the present."

"I couldn't have put it better myself, Deku. Tomura, I'd ask you to be thoughtful of the new age we are to bring forth. What you do now will determine what becomes of you and your future. For now, I want all three of you keeping an eye on Stain. Follow him, see what movements he makes. If he's not going to help us with our goal, perhaps he can be of use to us in other ways. When the time comes, I think you'll know what to do." All for One's screen went black, and Kurogiri relaxed as the boys went to go change into fresh clothes. He leaned against the bar and sighed heavily, and then jolted up when his cell phone rang.

"Master, what is it? Do you wish to change your orders to the boys?"

"No, no. I've been giving some thought to this, and I believe I may have chosen the wrong person to succeed me. Tomura does have the drive and passion of a villain but he lacks focus, desiring only to cause wanton destruction and needs to mature a bit more before he can be a true leader. Deku on the other hand seems to be nearly ready to take up my position. His intellect, maturity, and his conviction make him the perfect candidate."

"Are you sure, master? Tomura has been by your side for much longer, and Deku is simply a creation of Dark Mind."

"A fair point, and perhaps Dark Mind has played a hand in Deku's development into a villain. But nonetheless, should there come a time when we have to chose between the two, at the moment I'd prefer Deku. But who knows, perhaps Tomura will find his conviction in the end."

Hosu City:

Stain stood atop the water tower Kurogiri had found him on earlier, and didn't even turn when a warp gate opened behind him. Tomura and Deku stepped out, both glaring at the hero killer with disgust.

"Hosu City looks nicer than I thought." Deku looked around at the city skyline, while Tomura approached Stain.

"So, what're you gonna do here?"

"I will reform it, and blood must spill in order to do so. "Hero" is a title for those who accomplished great deeds! This city is full of false champions who care for nothing but money and fame! Until this world realizes it's mistakes, I will continue my work." Stain grabbed his katana and leapt off, heading to his next potential victim.

"He's so high and mighty. He's wasting his time focusing on such a small stage. One person at a time, hero by hero." Tomura uttered to the rest of the group.

"Agreed. He's nothing more than a serial killer with a perverted sense of purpose." Deku muttered, brandishing his knife.

"Still you must admire his dedication and focus. Wherever he appears, the crime rate lowers. Whether by fear or precaution, his actions do bring change from the heroes."

"So, now he's also making our job harder. The more heroes he attacks, the more safeguards the pros will put in place... We need to remove him if we want to remain in place. For the safety of our operations, he needs to be dealt with." Deku faced Tomura as he spoke, giving his "brother" an idea.

"Yes. He needs to go... Kurogiri, bring out the Nomus. Let's make it interesting for him. Let's crush his honor and pride first."

"Now that sounds like fun." Deku smiled as Kurogiri brought three Nomu out of his warp gate and they went off into the city. Moments later, they heard several screams as the Nomu attacked the city. Deku and Tomura pulled out a pair of binoculars.

"Seems like one of them went for a train. Hold on, is that... Who is that?" Deku squinted through the lens to see an elderly man in a white and yellow hero costume fighting against a Nomu, behind him was a young man in a red cape with spiked yellow hair.

"Well, that boy is Mirio, or Lemillion as he calls himself. Not sure about the short guy. Looks like they've got that one covered. But the others are making nice work of the rest of the place." The other Nomus were currently locked in battle with several heroes, all of whom were trying to hold their own.

Nearby:

"Those idiots are making a move, and they're noisy. I'll dispose of them later, after I finish my work here." Stain had the pro hero Native by the face, and raised his blade to strike. As he was about to complete his work, a young man ran down the alley and swiped his leg at the hero killer. Stain simply slashed his katana through the air, knocking the young man back and his helmet came off.

Rooftop:

"Now this is an interesting development." Deku glanced through the binoculars to see Tenya Iida on the ground near Stain. "Seems a U.A. student is trying to fight the hero killer."

"Who? The angry kid?"

"The four eyes who can run fast... seems a waste to see him die. But there are casualties in war."

"No, stop him! Don't let him kill them!" Izuku's voice rang out, making Deku grit his teeth. He looked through the binoculars to see the student and hero killer standing off, neither one attacking just yet.

"... Kurogiri... I've got a bit of an idea." Deku smiled as he pulled out his cell phone.

"Endeavor Hero Agency, how can I help you?"

"I'd like to report a sighting of the hero killer."

Nearby:

The hero Endeavor was doing patrol with his son Shoto and a few others from his agency when he received a call on his cell.

"What is it? ... are you serious?... We'll be there soon!" He turned to his companions. "There's an attack in Hosu City. Several creatures are causing chaos, and the hero killer is close by. Let's go! If anyone's putting that madman's reign of terror to an end, it's me!"

The trio watched as Endeavor and his group worked their way to the chaos of Hosu City.

"Stain vs Endeavor... place your bets, gentlemen." Deku chuckled as Tomura started laughing. Kurogiri turned to them both.

"An excellent idea, Deku. Either Stain kills the number two hero and causes a crippling blow to their ranks, or he gets arrested and we are free to operate in peace."

"Now, Kurogiri, your part is coming. On my signal." Deku turned his attention back to the hero killer and Iida in the alley. The boy was currently on the ground, unmoving from where he lay. The hero killer raised his bade at the pro hero, ready to end him.

"Now!" At this, Kurogiri opened a warp gate under Stain and sent him right into the fray of the Nomu's attack. Stain looked a bit disoriented for a while, but quickly got his bearings and went to work fighting against the monsters and pros surrounding him.

"HERO KILLER!" At this, Stain turned to see a burst of fire come at him. As he dodged out of the way, there stood Endeavor with a look of pure rage. "I'm here to end you!"

"Endeavor. The biggest false hero of them all. The one who cares for nothing but chasing a shadow of a truly great hero." Stain readied his blade and rushed Endeavor. The number two hero dodged and blasted Stain with a burst of fire.

"Shoto, you and the others deal with these abominations. This madman is mine." At this, the young boy and two others went to work assisting the other pros with the Nomu. The pros were struggling, but still managed to hold back the creatures with the new help they received. The villainous trio simply watched with amusement.

"Now this, THIS is a fight." Tomura chuckled as the pair went head to head, each doing their best to both dodge the other's attack while also land their own. Eventually, a Nomu went right for the pair of them, slashing at Stain's side with its claws and trying to bite Endeavor's head off. The fire hero dodged and blasted at the creature, which seemed to be unaffected by the flames.

"Oh, that's the flame proof one we made, right?"

"Oh, Endeavor is so screwed now." Deku chuckled as the Nomu and Endeavor went at it again, each trying to end the other. Out of nowhere, a blade sliced through the Nomu's neck and Stain was there holding his now bloody and bruised left side. As the Nomu fell to the ground, he held his blade high giving out a loud yell. Everyone watching him went stiff, not from his quirk but from the aura he gave off. He was emanating an air of rage, darkness, blood, pure fury and everyone who looked at him saw nothing but death.

"You false heroes! These streets must run with the blood of hypocrites! I'll make it right! I will reclaim the word "hero"! Just try to stop me, you fakes! There is only one man who I'll let kill me, a true hero! ALL MIGHT IS WORTHY!" As he let out these last words, he went stiff and simply stared ahead with a look into space.

"... Well that was a bit anti-climatic." Deku scoffed as the pros slowly ensured the hero killer was out of commission. Tomura stood up and walked over to the edge of the roof.

"Shame the Nomus were lost so easily, they were such good playthings. Ah well. Kurogiri, let's go home." As Kurogiri opened up a warp gate, Deku saw Tenya arrive at the scene and gaze at the hero killer. Shoto went over to him, and the pair began talking.

"That's right. The hero killer managed to get someone before we brought him to our hideout. It must've been someone close to you. I wonder how you'll handle not getting even with him." Deku smirked to himself and walked through the portal.

League of Villains Bar, the next day:

"The hero killer Stain is behind bars! Reports-" *click*

"Endeavor was on the scene and went head to he-" *click*

"The hero killer was paralyzed by internal bleeding due to his quirk-" *click*

"A group of creatures attacked Hosu City where the hero killer was-" *click*

"Were these creatures allies of the hero killer or just a diversion? Here's-" *click*

"- Given the appearance of these creatures, and the presence of three individuals in the area our reporters managed to catch on film, there is a possibly of the hero killer Stain working with this so-called "League of Villains" that attacked the U.S.J. at U.A. High School a few weeks ago-" *click*

"And there it is." Deku tossed the remote onto the bar, leaning back in his seat. "Now that Stain's caught, people are linking him to us. Just like we wanted."

"Why is that a good thing? He wasn't one of us." Tomura muttered, and Kurogiri brushed off his vest.

"Because now those inspired by Stain will come to us. By creating a link between us and Stain, the League has now become a beacon for all those who wish to bring down the heroes of this world."

"So, he's our new poster boy?" Tomura growled as there was a knock at the door. Deku looked on as it opened slowly to reveal their underworld contact Giran, who stood in front of two people in strange outfits. One was a tall young man with burnt skin and black hair. Behind him was a girl in a skirt and sweater with blond hair in two buns on the side.

"Shigiraki! Deku! Your little League has been the talk of the town lately. People say you're about to do something big soon."

"Who did you bring for us, Giran?" Deku glanced at the two people, and the boy in black stepped forward, looking at Tomura.

"So, it's really you. Gotta say, you look grosser in person than your pictures." He smirked at Tomura and the girl stepped forward.

"Wow! It's the weird hand guy, and the green haired boy! You're cuter than I thought you'd be, greeny. You guys are friends with Stain, right? Let me join the League, I wanna be in your group!" she rambled out with a school-girl voice, leaving Tomura and Deku to just glare at them with disbelief. Deku turned to the bar and grabbed a bottle of a shelf, only to have Kurogiri snatch it out of his hands.

"No." Kurogiri scolded him, and Deku simply crossed his arms and leaned against the bar. This was going to be a long day.

U.A. Conference Room, later:

Principal Nezu had gathered a few of the teachers, All Might, and Gran Torino was there as well. His involvement with the Hosu incident as well as him giving Mirio additional training with One for All was what lead him here.

"We have a problem. Now that the hero killer has been caught, people are making a connection between him and the League of Villains. Stain's ideologies will be spread through the media as people want to understand his motives, and that'll inspire other villains to pursue the same goal." Torino fiddled with his hands as he addressed the rest of the pro heroes.

"Which is where the League comes in. Now that they've been linked to Stain, others will see them as a group with an ideology instead of delinquents that attacked U.A. for simple destruction. If the group assembled under that banner grows large enough, it'll be a threat no matter what." Eraser Head spoke up, and All Might trembled slightly in fear.

"Earlier, Tsukauchi told me the Nomu that attacked during the USJ incident had multiple quirks. The way it was made to be my equal, the savagery it had going up against me, what he told me. It all points to him. But for him to have survived those injuries, for him to be coming back..."

"All For One. If he is behind all of this, he's getting bolder. He's eliminating those who stand in his way, and using who he can to achieve his goals." Torino spoke up, and Nezu decided to address the room.

"For now, we should focus on what has happened. Stain attacked a number of heroes, and the League unleashed Nomus before retreating themselves. Both of those threats are now taken care of. What we need to do now is prepare for what comes next. The League will most likely try to expand their numbers, and we need to be ready should they attack again." At this, the room was dismissed, and All Might turned to Gran Torino.

"Sir, I understand Mirio was with you the other night. Is he okay?"

"Yeah, he got into a mild scrape with one of those creatures, but managed to hold his ground. Doctors gave him a full work over at the hospital, physical exam, blood sample, the works. Guess they're being cautious."

"Yeah... I should tell him. About All for One." All Might clenched his fist. "If he's truly behind all this, Mirio deserves to know what he's up against."

All for One's Medical Lab, later:

"Doctor, how goes your progress?" All for One sat in his medical support system, watching the bald man shuffle about the room.

"I've completed the conditioning process on another two Nomu, and begun creation of two more. As for the other request you had, I believe it may have merit." The doctor pulled a vial of blood out of his coat pocket and placed it on the lab table.

"You're certain it's from him?"

"Positive. Had it confirmed by our agent herself. This is a blood sample from Mirio Togata. Now, all we need is the other sample and the device we've heard about. But I'll be honest, this has to be the craziest thing you've thought of, Master."

"The line between genius and insanity is often blurred. But, if we can succeed, All Might and his successor will be powerless to stop me. See to the necessary preparations for retrieving the other items. And see to my injuries afterwards, I want to be healed as much as possible soon." All for One waved the doctor off, and the man nodded his head and walked away. All for One smiled to himself before drifting off to sleep, imaging what the future held for him and his two young protégés.

Deku's Room, that night:

Deku was sound asleep, dreaming of what had happened earlier, the hero killer's face glaring at him. His dream then faded away in gray smoke and there in front of him was Izuku.

"... Are we really going to do this again? You never win."

"I'm not going to let you control me anymore! I want you out of my head."

"You're in MY head, brat. And if you want to lose again, fine." At this, the two charged each other, and Deku immediately gained the upper hand. The two had done this dance almost every night, each fighting for control of the body. Deku managed to land a few blows one after another, leaving Izuku panting.

"Just give up. I'm stronger than you, I've always been. All you can do is yell into the storm." Deku landed blow after blow, and Izuku tried to block but was slipping up with each blow.

"... I won't let you use me anymore." Izuku threw a punch that Deku side-stepped, and then followed up with a sweep of Deku's legs. As Deku went down, Izuku got on top of him, throwing punch after punch. Deku raised his hands to block the blows, and Izuku kept up the attack.

"You... little... BRAT!" Deku shoved forward, knocking Izuku off. As his kinder persona was getting up, Deku landed blow after blow. "Weak! Pathetic! Powerless! Stupid! Little! Midoriya!" With each word, another blow, until Izuku was on the ground unmoving and breathing slowly.

"You... won't... win." Izuku muttered before Deku simply put his foot on Izuku's chest.

"I just did." At this, the gray smoke surrounding them swirled around and everything faded away as Deku woke up. Holding his head, he grinned to himself and went back to sleep.

Aaaaaaaaaaaaahhhhhhhhhhhhhhh! Finally! It's done! Oh my god, this chapter took forever! Well, to be fair, I WAS trying to condense about four/five-ish episodes into a single chapter. Sorry in advance for the massive chapter, unless you wanted more to read, in which case here you go! Anyway, with one less thing going on in my life, I'll have more time to work on the story. So, hopefully I can get chapters out quicker, but I make no promises. Until next time, thanks for reading!
