Deku vs Kacchan

Izuku woke up early that morning. He quickly got dressed into his "villain" outfit which consisted of a black hoodie vest, black pants, black metal arm and shin guards and a black metallic mask which covered his entire head. He also wore combat boots and a belt with various tools such as a taser, a grappling hook and several small projectile blades. The outfit he had mostly forged himself with the exception of the helmet (Kurogiri gave it to him after the meeting). He had a feeling he would one day be out fighting with the League but he wanted to make sure his identity wouldn't be compromised. Still he was ready to face Bakugo.

At the bar

Izuku met up with Tomura and Kurogiri where he also met their large entourage. Izuku didn't know what to think of the group. He hadn't seen them in action yet but at the same time they just looked like a bunch of regular thugs. What caught his attention was the bird like creature who looked as tall and muscular as All Might. "This must be the guy," he thought. Izuku didn't have much time to think however as Kurogiri's quirk completely absorbed him and everything around him.

Unforeseen Simulation Joint

They arrived at an area in that had various buildings with different natural disasters going on for each one, as they were supposed to.

The group of villains looked to up to see the students and teachers at the entrance, who had also noticed them. Strangely enough All Might wasn't there. Izuku didn't care though, that wasn't why he was here. He started to scan the student's faces until he came across a familiar one. Wearing gauntlets and an outfit that matched his personality was Bakugo giving his usual glare. The moment he saw him Izuku felt a sudden flood of anger. He wanted to fight him, he wanted to hurt him, however, to do that he would need to get him alone first.

"Kurogiri could you warp me and 'you know who' to an area where we won't be disturbed?" he asked politely.

"Of course. I'll also send the students to other zones where they won't be able to interfere," he replied.

"Here comes Eraserhead," Tomura butted in.

The former pro hero attacked the group and was starting to fight off the thugs like they were nothing, it seemed like they were amateurs after all. The students and 13 were running toward the exit.

"Kurogiri," Tomura started.

"I understand," he replied. "While I'm at it I'll send you Deku to a place for your battle. Expect that boy to be there in a few minutes." Izuku nodded.

Kurogiri's power took hold again and Izuku was in a ruined city area. It was desolate and he was on flat ground.

"Perfect," he thought.

This would be the perfect place to fight Bakugo without interference.

After waiting for two minutes Kurogiri's mist appeared again bringing an angry Bakugo with it. At first Bakugo didn't notice Izuku, he just swore about Kurogiri.

"That fucking bastard, those fucking villains, I'll fucking kill them," he shouted. "Swearing and death threats," Izuku thought. "Nice to see that he hasn't changed a bit."

Bakugo examined the area around him when he noticed Izuku.

"You one of them?" he asked in a murderous tone.

He didn't pay attention to his classmates, not that he needed to, they were all beneath him. Izuku took up a fighting stance as an answer. Bakugo smiled sadistically and punched his right fist into his left hand while causing an explosion as form of intimidation.

"This will be fun," he snarled.

Izuku felt slightly nervous about fighting Bakugo. "Give him hell". Razor's words echoed in his mind and he was calm again. He stared at Bakugo.

"That's right I've trained for this," he thought. "I'm not the same weak individual that you used to beat to a pulp. I'm Deku, the villain that will defeat you." With that he charged at Bakugo.

Seeing his enemy move Bakugo started to swing his right arm. However, Izuku was prepared for this and much faster too. As soon as Bakugo swung his arm Izuku grabbed it, turned, and flipped him onto his back.

"When you get someone on their back get on top of them and punch them as hard as you can and as many times as you can."

Izuku started doing just that. While doing so every memory of Bakugo bullying came back to him which made his punches more vicious.

"This is strangely satisfying," he thought.

Knowing he'd be knocked out soon Bakugo caused an explosion to faze Izuku and then another one to get him off. Bakugo stood up. His mouth was bleeding from the punches, this made him pissed as hell. He screamed out in anger and unleashed a flurry of expolsions on his opponent.

Izuku flipped from place to place dodging them with relative ease.

"This is the guy I was scared of," he thought.

He couldn't believe how well he was holding his own against Bakugo. Months of training were paying off, it seemed that all Bakugo had to rely on was his quirk, he had no training what so ever in hand to hand fighting.

"So much for having a powerful quirk," Izuku thought.

Izuku was actually surprised at the damage he'd done to Bakugo, he was a lot stronger than he thought. Compared to Razor he was nothing.

Seeing that he wasn't doing much at long distance Bakugo rushed towards his enemy swinging his right again.

"Seriously does he think that will actually work this time," Izuku thought.

However he was wrong. Bakugo used his quirk to launch himself over Izuku.

"Got you now," he shouted while successfully hitting Izuku with a lot of explosions.

Izuku lay on the ground with his clothes slightly torn and a crack in his mask.

"How'd you like that," Bakugo sneered.

He assumed he'd won, he couldn't have been more wrong. A few seconds later Izuku stood up not showing any sign of feeling injured, something which shocked Bakugo.

"No fucking way," he spluttered.

Bakugo's attacks may have been painful but they didn't matter that much to Izuku. He was used to this sort of pain, well actually he was used to much worse. Razor didn't play around.

Bakugo moved to attack again but Izuku came in very quickly and kneed him in the stomach. Bakugo flinched with pain. Izuku didn't stop however. He grabbed Bakugo by thee shoulder and started to repeatedly punch him in the stomach. Bakugo vomited slightly from this. Izuku then grabbed him by the shoulders and headbutted him so hard that part of his mask broke off showing his right eye. He had broken Bakugo's nose also as blood flowed from it. Izuku then let go of Bakugo, leaned back, and side kicked him up into the air. Bakugo tried to retaliate but Izuku was quickly behind him and grabbed him by the collar. He then ran and threw Bakugo into one of the ruined buildings where crashed through the wall.

When Izuku saw no movement he assumed he was unconscious.

"I did it Razor. I won," he thought as he turned to leave.

Izuku was hit by another explosion on the back, though this time he managed to remain standing.

"Hey," came a hoarse voice. "This fight isn't over you bastard. So don't turn your fucking back on me."

Izuku turned to see Bakugo standing, blood running down from his forehead and one or two bruises on his arms. He looked rather pitiful, he looked like the state he'd put Izuku in for years. Strangely enough, it made Izuku happy to see him this way.

"I should have expected him to not go down without a fight," he thought.

Bakugo stared at his opponent's eye for a moment. There something familiar about it.

"Don't think about it. Just finish him off," he thought.

For the first time in his life he was hurt all over. He was used to dealing pain, not receiving it. The whole sensation was strange. He needed to finish it quickly. He held up his arm and reached for his gauntlets trigger. They stored up his sweat, which was nitroglycerin which allowed him to create explosions. With the amount stored up in them both it would be like firing a rocket launcher.

Izuku didn't know why but something told him to get as far away from Bakugo as possible. If he was reaching for his gauntlets then they clearly weren't just for show. He started running and as he did Bakugo shouted "Die".

Suddenly there was a huge explosion that came at him very fast. Izuku instantly pulled out his grappling hook and shot it towards the nearest building on his left. The explosion came at him too fast however. While he managed to avoid death part of his legs had been burned. Izuku examined the damage Bakugo had done, it was very widescale.

"What the fuck is wrong with him? He could've killed me or one of his allies in that," Izuku thought alarmed.

"Ha. How'd you like that?" Bakugo yelled triumphantly.

Clearly he had thought he had won.

"Ok I've had enough of this," he said to himself.

He walked toward Bakugo who couldn't believe his eyes.

"Why won't you just stay the fuck down," he screamed as he prepared to attack him again with his other gauntlet.

Izuku was prepared this time though. He threw one of his blades at one of Bakugo's hands, causing him to howl in pain.

"When your in pain put all your power into that point of pain and deliver the final blow".

Izuku ignored the pain in his legs and charged at Bakugo. Bakugo tried to defend himself with is quirk but Izuku leaped up, spun and delivered a kick to Bakugo's face with full force. Bakugo fell back and his face landed hard onto the ground. He didn't get up. Izuku checked his face, he was unconscious.

"I won," he declared before walking off.

"Kurogiri I'm finished over here," Izuku told him over the communicater in his mask.

"That's good to hear. I had a camera or two around your area so your battle has been recorded for Razor to see," Kurogiri told him. "All Might's here by the way, and the pros will be here soon also. I suggest you make your way back to us at the centre."

"I will," Izuku replied.

As he walked he could really feel the pain in his legs, Bakugo did a better job than he thought. "I'm almost there now," he said to himself as trudged along.

Suddenly he heard a scream. He turned to see a girl in pink being held to the ground by one of the thugs. She looked terrified.

"Now then," the thug declared. "Let's have some fun shall we."

Izuku had a very good idea of what he was about to do and headed towards them. He may have been a villain now, he may be a colder and serious person, he may be willing for heroes to die, but rape, that was a different story. Despite his time with the League Izuku still possessed a certain degree of morality.

The girl looked terrified when he saw another villain appear.

The thug turned to Izuku and said "What do you want? Can't you see I'm busy."

Izuku, annoyed with his tone, tased in the neck (He didn't have much strength left to fight) knocking him out cold. The girl was stunned at what just happened.

Noticing her expression Izuku said "If you don't want that sort of thing to happen to you then I suggest you run."

At first she didn't move, she was still shocked. Izuku glared at her and yelled "Now". With that she scrambled away while still looking at Izuku. He then turned and proceeded to where his allies were.

He arrived just in time to see All Might blast that bird like creature out of the building. There were a bunch of unconscious thugs. Tomura was also there with Kurogiri looking very pissed off.

"Are you guys alright?" Izuku asked them.

"Nomu got beat," Tomura raged.

"So that's what that thing was," Izuku realised.

He made his way to them. He also looked at All Might. It was strange, his childhood idol was now his enemy and a kill target for his new group.

All Might was staring at the new arrival.

"Great just what I need, and I've already gone past my limit," he thought.

He inspected him further. There were burn marks over him and he was slightly limping.

"He's injured," he realised. "Those marks, did Bakugo do that to him."

He knew the boy well enough to know what kind of damage he could deal.

"I take it you finally defeated that explosion user," Kurogiri said.

"They are talking about Bakugo," he thought.

"Yeah I beat him," the new villain said with pride. "I beat him to a bloody pulp."

All Might tensed slightly in anger of this. "You," he said in a furious tone.

The villain turned to look at him (he had a green eye from what he could see). "Relax he isn't dead, just unconscious," the villain told him.

All Might was both slightly relieved and surprised at this.

"What the hell Deku," yelled Tomura."Why didn't you finish him off?"

"You know very well that I don't kill," he retorted. "That was one of the conditions I set when I joined this group remember."

Now All Might was definitely surprised. Deku, he wasn't a killer yet he joined this band of villains with some conditions. Just who was he?

Izuku noticed that All Might was steaming.

"He's reached his limit," he realised.

Izuku remembered that from their last encounter All Might had told him that he can only use his power up to three hours a day, when he steamed he reached his limit and reverted to his real form, something no one else knew about. Izuku didn't know why but something told him to keep his mouth shut at that moment. He was in possession of a very valuable piece of information. If he blurted this out now All Might would most definitely know who he was. Not only that but they were at a disadvantage with so little forces and the pros on their way.

"Tomura, Kurogiri, lets withdraw for now," he told them. "We're at a serious disadvantage with him here and the pros on their way. Also our ace was just blasted out of here and our forces are down."

The two just stared at him.

"He's right Tomura. The situation isn't in our favour," Kurogiri stated.

Tomura scratched his neck in frustration.

"Ok fine," he relented.

He turned to face the Symbol of Peace and said "All Might beware, because your days as the symbol of peace are numbered."

All Might grunted in response. "We'll see about that."

For some reason though he was still staring at Deku.

"From the sound of his voice he seems to be in his teens. Also that eye, why does it seem familiar?" All Might pondered.

This boy probably wasn't that much older than his students. It made him sad to think that someone this young had become a villain. His thoughts were interrupted however at the one called Kurogiri using his quirk.

Kurogiri's mist then surrounded them and they disappeared from the area. During the transport however Izuku lost consciousness.

At his apartment

Izuku woke up surprised to see that he was in his apartment. He moved his legs slightly but he felt no pain in them. He inspected his body. There were no signs that he'd ever been injured.

"It wasn't a dream if that's what you're thinking," came a voice he knew all too well.

Izuku looked to his right to see Sensei (or All for One as he was usually known) sitting at the table drinking what could've been tea or coffee.

"Hello Deku," he greeted the boy. "It's good to see that you're awake."

"Sensei you're here," Izuku replied stunned.

He had spoken with the man before but had never met him in person.

"Why are you here?" Izuku asked before he could stop himself.

Was he in trouble? Once again Sensei seemed to know what he was thinking.

"You're not in any trouble. I came today to sort out a few issues with the League and just thought I'd check up on you. You came back with a few burn injuries and have been out for nearly two days now. We had to use that regeneration drug of yours though," he explained.

"Thank you," Izuku replied. "However I'm guessing you didn't come to just check up on me."

He knew Sensei well enough to know that he wouldn't come here in person unless it was very important. Sensei grinned.

"Observant as ever I see," he said. "You're right I came here to discuss something with you. Something that happened during the assault on UA. And I'm not talking about your fight, that was impressive."

Izuku sat up straight and faced him.

"It's about your decision to retreat. There were cameras around the area so I saw the entire ordeal. While your reasoning was logical, and the pros did show up shortly after you'd left, there was something else that made me curious," he informed Izuku. "Why didn't you tell the others that All Might had reached his limit?"

Izuku was definitely surprised now.

"If he knows about that then he must have a history with All Might," he realised.

He took a deep breath. He needed to be careful about his answer.

"It's because I knew it that I didn't tell them," Izuku explained.

"Oh," Sensei responded amused.

"Let me point out something. I told you about my first encounter with All Might. During that encounter I learned about his little weakness, however, I also learned something else. He told me that not a lot of people know about this. Therefore, since I am one of these people blurting it out would have lead to my identity being exposed," he explained. "Besides, you clearly know about it too yet you didn't tell the others so you're in the same boat. How you know it? From what I've seen of you every time All Might has been mentioned you got angry, meaning you've some sort of history with him. So tell me, am I wrong?"

There was silence.

"Maybe I went a little too far," he thought nervously.

However, Sensei started laughing. Izuku was now confused.

"It appears I underestimated you Deku. You are correct with that assumption," he told the boy. "Your answer for not telling the others is also acceptable."

He wasn't joking either, if Deku had figured all that out from observing then he was a lot smarter than he originally thought.

"My past with All Might, well to explain I would have to tell you about my origins, something which I have no intention of doing," Sensei told Izuku. "However if you know about his weakness, then I can tell you about his quirk."

Izuku shifted slightly in response. No one knew the exact details of All Might's quirk, people just assumed it was strength enhancement.

"All Might's quirk is known as One for All, one passed on for generations."
