There was a loud ringing in katsuki's ears. He could barley keep his eyes open. Where was he? 

The last thing katsuki remembered before passing out was when he was fighting with the league when they tried to convince him to join them. He then grunts as he tried to move his body, realizing he's chained to the wall

"The fuck?!" He grits his teeth, trying to pull his wrists out the sliver cuffs, he tries to use his quirk but the cuffs tightens around his wrists, he grunts then looked around the dark room "oi! League of idiots! Where the hell are you huh?! If you don't get me out of here now I'll kill ya!!" He yells in the empty dark room, his yell echoing in the room. Did the league really just kidnapped him and then threw him into a room? Such a good "team"

He then tenses up when the door slowly opened to reveal a crazy blonde girl and a emo lookin villain, also known as himiko and dabi.

"Jeez you're loud as hell. I could hear you down the street." Dabi says with sarcasm as he rubs the back of his head as himiko giggles at dabi's words "what the hell are you gonna do to me you bastards?!" Katsuki yells at the two villains, gritting his teeth "well the boss still wants you to join! So we're just gonna force you to join!" Himiko grins evilly as she pulls out her knife and dabi lights up his hand with a grin

Soon after the two left the room, katsuki coughing and grunting. He had cuts from himiko all over his body and his neck and arms were burned by dabi but katsuki still refused to join, he'd rather be torn apart then become a crummy villain

Soon day after day they kept torturing katsuki but he still refused, one day toga came in just by herself. Katsuki was already bleeding from head to toe, he looked up at her before coughing out blood "wow! Look at how much you bleed! Too bad I couldn't get the others to bleed like this." She pouts as she plays with her knife, katsuki snarls before finally breaking out the chains and sends an explosion at her, she shrieks then moves out the way "I don't think so!" She grins before pinning katsuki to the ground. "Tsk tsk, I was really starting to like you, bakugo. But I guess we all can't be winners." Her grin widens as she trails her knife down katsuki's wrist

"You know we warned you about using your quirk. We even fed you and gave you a choice to join us but here you are attacking us again. But I'll make sure you won't hurt me or them again." Toga then chains katsuki's wrists again before pulling out her sharpest knife and moving it against katsuki's wrist, already making blood draw. Soon Toga then starts cutting the skin making katsuki shout in pain "what the fuck are you doing? Aghh!!" He grits his teeth, shutting his eyes as her knife start cutting down to the bone, blood spilling down katsuki's arms as he screams and yells in pain "it'll just take longer if you keep squirming." Toga says lowly as she glares down at the screaming blonde, she finally then cuts katsuki's hand off, katsuki slowly turns to the detached hand next to his face before screaming

Toga then goes to cut the other one, katsuki tries fighting her but all he does is get blood on her as he waves his handless arm around as blood spilled everywhere. When she's done she unchains katsuki. He looks down at his bloody arms breath shaking as he screams in pain and frustration. He can't believe he just let Toga cut off his arms! He tries activating his quirk but without his palms there wasn't even a spark, he yells as he slams his wrists on the floor before passing out from blood loss

katsuki was suffering from the villains, his breathing was shaking and he couldn't think not see straight. At least the villains bandaged him up but this was insane! He couldn't even use his quirk anymore! Did they just expect katsuki to fight armless?! He then gets thrown back into reality as he saw Toga, dabi and shigaraki step into katsuki's personal hell "I think it's time we give our friend a little...upgrade." Shigaraki says with a evil grin. Toga and dabi then grab the back of bakugo's shirt and start dragging him out the room, katsuki struggles and tries to fight back "let me go! I'm not going through anymore of your shit!!" Katsuki yells as he squirms more. they then throw katsuki into a room and shut the door "hey!!" Katsuki shouts before banging on the door with his wrists "let me out! If you don't open this door right now I'll kill you!!" Katsuki yells before hearing a slow clap, katsuki slowly turns around to see a man...no not just any man...

 

all for one.

 

"well, well...so this is the number one katsuki bakugo everyone talks about." The potato looking man grins as katsuki stood up "it's you, you are the villain all might use to fight!" He yells "oh wow, seems like you seen our fights before. Shame that'll end soon." He lightly shock his head "end soon? Ugh! I don't care what your gonna do! I'm tired of this crap!" Katsuki yells before lunges at all for one. "I'm going to end yo-" he then gets cut off by all for one catching his face with one hand "tsk, tsk. I honestly thought you were stronger than this. Well if you still had your hands, you'd probably could've had a chance." All for one says with sarcasm, All for one then activates his quirk and katsuki screams when he felt his quirk slowly getting taken from him. He tried to pull himself off from all for one's grip but without his hands he couldn't budge. He slowly closed his eyes. Feeling his life slowly getting taken away. Was this really the end for him? This is such a pathetic way to die...

katsuki then woke up in a pretty broken room with the walls falling apart, the bed just being a broken mattress, no windows and blood stains on the floor.

Katsuki got up before he stared at the mirror, confused as he stares at his features. His neck had slight burns, his right face was covered in bandages and he just looks tired. He then puts his hand nub on the right side of face. He then felt something faintly shock him so he immediately pulled away "What the hell?" He looks down at his bandaged hand nub, he looks back at the mirror before struggling to take the bandages off his face, once he managed to do it, he sees glitches on his face it changed it's position, but still stayed on the right side of his face. and it's colors every millisecond

"What the...?" He then attempts to touch it again before getting shocked once more "agh!!" He shut his eyes before opening his left eye, seeing small glitches on his hand nub. Shaking his arm like crazy to get rid of it "what is going on?! Where am I?! Who am I?! Why is this on my face?!" Katsuki says out loud as he panicked, he then froze when he heard the door open

He turns over then saw the league of villains but he doesn't remember who they are so he just stares at them "never thought you'd wake up." dabi says with a grin "those heroes really did a number on you, huh?" Toga says with a giggle, what did she mean by that? "I'm sorry...heroes did...this to me?" Katsuki asks, approaching the three "Mhm, we saw the heroes take away your limbs and we just managed to find you so we saved you and patched you up." Shigaraki says, straight up lying but katsuki doesn't realize. He doesn't realize that they done this to him.

Next thing katsuki knew he was sitting at inside the abandoned warehouse or what the league calls it, their new base. Since the heroes destroyed the bar they had to find somewhere new to hide. "Apologies we can't get you any prosthetics, no name." Mr compress Apologized to the blonde "uh..yeah, it's fine." Katsuki looked away from the masked magician. What was he supposed to say? He barely knew these people. that's what he thinks anyway.

 

meanwhile back at U.A high school

 

A sudden slam was on the principal's desk "it's been weeks since kacchan got kidnapped! What do you mean you haven't found him yet?! The villains could have killed him for all we know!" Izuku yelled at nezu, the principal. "Midoriya I know your worry for bakugo but the heroes are really trying their best they can. After the fight between all for one and all might, the villains vanished. They could be anywhere with bakugo." Nezu calmly says "well then let us out there! We can help find him!" Izuku clenches onto his blazer but the mouse shook his head "I'm afraid I cannot let you do that until you get your hero license. Once you and your class get their license, you're allowed to find bakugo. But right now? Let the heroes do their job." Nezu said, once again in a calm tone. Izuku wanted to fight back but he knew he needed to wait. "I understand.." He muttered before looking down

Izuku walked back to the new U.A dormitories, that nezu got for all the classes in U.A. izuku got onto the fourth floor, walking to the dorm that katsuki was supposed to have, he runs his hand across the name of his childhood rival that was built into the wall. He let out a sigh "I know your out there. I won't rest till your safe back and sound." Izuku muttered to himself before pressing his head against the door. "Just a few more days and I'll come searching for you." He closed his eyes as he talks about getting his license and finding katsuki.

Over the past few days, class 1A got stronger while the league of villains started finding more people to join them, katsuki on the other hand was trying to work out his new quirk and is trying to remember anything at all. He then looks over at the female blonde, himiko Toga. Skipping out the warehouse "hey, where are you going?" Katsuki asked Toga which made her stop in her tracks "oh! I'm gonna see the heroes!" She grins widely "apparently they are getting their permission to be a heroes and the two most cutest people in the world are gonna be there!" Toga giggled as she blushed, talking about izuku and ochako. "Could I come? I wanna know more about the heroes." Katsuki took a step closer to Toga but she holds up her hand "no can do. You need to rest." She then points at katsuki's bandaged nubs "but I'll be back soon!" She giggled once more before going into kurogiri's portal

Before he could speak again, the portal shuts. He grits his teeth then slams his foot on the ground, making the world glitch for just a second "I don't even know these people and they just make me...so mad! Why?! I feel like I know them but I can't remember! Ugh! Who am I?!" Katsuki yelled before kicking a small rock before hearing a splash "huh?" He looked over at the sound before walking to the nearby stream "huh..at least we'll know where to get fresh water." The blonde thought to himself with a shrug, he saw a broken log going down the stream. A image of a small hand flashes in his head "agh!!" He yells as the glitches on his face go crazy on his face and causing pain "ahh!! Stop! Stop!!" He begs for the glitching to stop before backing away from the stream, the glitches calming down when he gets farther away "oh my god..." He whispers before quickly getting away from the calm stream and back to the warehouse where he sat on the stone cold floor and hugged his knees, nothing but confusion and a hazy memory filling his mind.

"Don't mind her." A voice said that made Katsuki look up, it was Kurogiri. He kneels down in front of Katsuki and took his bloody nubs for a daily clean "we can't let you out in public yet, you still need to heal." Kurogiri says, he was lying if Katsuki stepped into the city he'll get recognized immediately and taken in for questioning. "...can't I get a hand replacement or something..?" Katsuki quietly asks as Kurogiri takes off the bloody bandages "I know you've been struggling with no hands for a few days now but we're trying our best to find you a replacement." He says, wrapping the bandages around katsuki's wrists and tying them securely. "...thanks." Katsuki says quietly before kurogiri got up and walked away. Katsuki pulls his knees to his chest and buries his face in his knees

The next day everyone was chilling in the warehouse before watching twice enter the warehouse with another man with a long bird mask, katsuki watched from the dark as shigaraki talked to him, he wasn't allowed to be seen by new members since the villains couldn't risk them seeing him. He watched shigaraki approach the bird man before hearing him telling the other to leave, one of the other members, big sis mange. Got her weapon ready and went to go attack the bird man. When she did she just...exploded. Leaving the league shocked "no! Big sis mag!" Toga yells as blood lingers in the air. Katsuki watches the shadows as Mr. Compress tries to seal the man but his arm was exploded off and was thrown to the side, shigaraki jumped in and one of the bird man's henchman jumped forward, getting decayed by shigaraki. Twice immediately catches Mr. Compress,  when more henchman charged that's when katsuki finally comes out of the shadows to help but they were already leaving. The bird man tossing a card towards shigaraki then they were gone. Katsuki stares at the destroyed wall before quickly going to Mr. Compress's side.

The league had to run to a new hiding spot, when they did they got Mr. Compress to a doctor. Katsuki was sitting on a crate before seeing shigaraki "...where are you going?" He asks, getting up and looking at shigaraki. Shigaraki paused and looked at katsuki "I'm going to go meet that bastard." He says and katsuki frowns "that freak who killed mange and hurt atsuhiro?! Are you seriously going to go through that damn business deal?!" Katsuki yells and shigaraki faced him "mind your own business, glitch. I have a plan. Stay here and wait." Shigaraki says with a dismissal wave and before katsuki could say anything else shigaraki already left the building. Katsuki frowns and kicks some small rubble with his messed up sneakers before squatting on the ground "so damn stupid..." He murmurs under his breath.

When shigaraki returned everyone was gathered in an abandoned office "...you want us to work with hassaiki?" Twice asked, katsuki sitting cross legged on the old floor next to Mr. Compress, who was getting a robot arm attached to him by grian, katsuki was looking down at his new robot hands and try to get use to the weird feeling. "Yeah. Why do I have to keep repeating it? Their plan has some potential. So from today on, Toga and twice will be yakuza members." Shigaraki says, standing in front of everyone. Katsuki couldn't even process twice yelling at shigaraki and toga holding a knife to his neck. He only cared that he now had hands after days of just having nubs. It was hard to curl his fingers and use his fingers to point but he had hands now.

"Glitch." Shigaraki calls out and katsuki looks up to see shigaraki without the hand on his face, it made katsuki tense up despite the soft look on shigaraki's face "at the end of our plan we'll get payback from the hassaiki. We can't leave you alone. So you'll come with us." Shigaraki says and katsuki's eyes widen, he was finally allowed on a mission? He was going to get his first revenge on that bird bastard. He looks down at his new robot hand before looking back up, now on a moving truck with dabi, Mr. Compress, shigaraki and spinner. "Let's go." Dabi says before shooting a large blue flame at a police car and a ambulance that held overhaul in it. But a sand hero that was in the police car blocked dabi's flames to protect the police car "ugh. Of course they sent a hero with him. What a pain. Spinner, Slow down!" Shigaraki calls out to spinner, in the driver seat spinner starts slowing down the truck. The sand hero managed to saw katsuki "hey..isn't that the missing kid from UA?!" The hero says and because he was distracted shigaraki jumped off the truck and landed on the police car. The hero quickly caught shigaraki with his sand but Mr. Compress flicked his blue sealed ball under the car and large rock came out, sending the car flying.

Shigaraki jumped out the way and landed on the ambulance as dabi, Mr. Compress and katsuki jumped out the moving truck. The ambulance drove off balance and landed on it's side. Soon shigaraki and katsuki dragged overhaul's stretcher out the ambulance while dabi and Mr. Compress handle the sand hero. Shigaraki kicks the mattress once it was on the ground. Katsuki went back to the ambulance and got the quirkless bullets before giving the case to shigaraki. He stood by and watched as mr. Compress walks over and just seals overhaul's arm while shigaraki puts away the case and decayed overhaul's arm. Katsuki winced when his arm was cut off but it was satisfying to see. They then looked up when they heard spinner honking the horn "backup's coming! Let's gotta go!" Spinner calls out and shigaraki starts walking "welcome to the club, prick." Katsuki says to overhaul before following shigaraki, dabi and Mr. Compress back to the truck. Leaving the screaming overhaul behind.

 

The four immediately get back into the back of the truck and spinner quickly drives off, leaving the chaos behind for heroes and the police to deal with. Katsuki stands in the corner of the truck as it moved and something was on katsuki's mind. What was that sand hero talking about? Missing kid? From UA? Did dabi blind his vision or something? As katsuki was thinking the glitches on his face started glitching violently like before at the river. Katsuki yells in pain and grips his head as he backs up against the truck wall and slid down into a curled ball. Shigaraki looks at him before quickly calling out to spinner "spinner! Drive faster!" He yells before slowly approaching katsuki "it's just a drawback. It'll go away." Shigaraki says but katsuki shook his head, moving his head caused some of the glitches to stick to katsuki's prosthetic hand "I want it to go away now!!" He screams before slamming his hand against the floor, the glitches on the hand made contact with the truck's floor and it started glitch out violently, it made it's way to the driver's area and spinner was forced to swerve and slam the truck against a barrier, when the glitching finally stopped the truck stopped as well, the battery dying almost immediately. The five quickly got out the truck in case it'll blow up "what was that?!" Spinner yells as shigaraki just looks at the truck then at katsuki, causing him to tense up "...so that's how your quirk works..." Shigaraki murmured before turning to the others "it's fine." "Fine?! He could've gotten us killed!" Spinner yells, gesturing to the truck and katsuki "I said it's fine." Shigaraki repeats, adjusting the hand on his face "if we kept going on this road the police would've realized we were still in the truck. In this case glitch got us saved." Shigaraki says and spinner couldn't find himself to argue against that but he was still annoyed
