AN: Hey everyone, we are back with another chapter, I'm back kind of. I got an announcement at the end ao stick around, so without further adieu let's just jump into it!

Mistakes

The air around Izuku sizzled as lightning strikes struck the ground around him. Loud booms echoed throughout the city as fist met flesh. Rumbling was heard as buildings fell around him.

The city was in chaos, civilians ran for their lives, heroes tried their best to save them. Everyone watched as their city fell right before their very eyes. And there wasn't a damn thing they could do about it.

The fight between Izuku and Stain went back and forth, blow for blow. Izuku would punch Stain in the chest, only for Stain to strike back with an uppercut.

Both speedsters were so into their own battle that they didn't notice everything going around them. I'm an instant Stain managed to grab Izuku's arm and throw him on his back. His mask now exposing his forehead but still hiding most of his face. "You're much more vicious than the other Izuku. I wonder why?" Asked Stain as he now stood over Izuku.

Izuku gritted his teeth and in a flash of green he got up and charged his lightning on his right arm. "That other me was weak!" Yelled Izuku as he punched Stain with his lightning charged fist.

With the extra power behind his punch Izuku sent Stain flying into a car. Metal folded and broke as Stain stuck to the car. "Weak you say, quite the opposite actually. That Izuku was calm, calculated, and focused. If it was a straight fight, I wouldn't have stood a chance. But once I took the thing he valued most in the world he lost it. All self control, any semblance of the man he was, was gone. That is what made him go mad, why he lost! Just like you're doing right now."

Pulling himself free, Stain looked up to find Izuku walking towards him. Blinking once, Stain flinched when Izuku appeared in front of him. With one swift motion Izuku kneed him in the stomach. Falling to his knees Stain clenched his stomach, "I'm not that other Izuku." said Izuku glaring down at Stain.

After a short while Stain began to laugh, "That's where you are wrong. You and the other Izuku are the same."

Running in Izuku tried to punch Stain down but was surprised when his fist was caught. Izuku's eyes widened, "H-How?"

Getting to his feet, Stain twisted Izuku's wrist back causing him to grunt in pain. "I told you. The same."

With a swift motion Stain punched Izuku's side, breaking a few ribs. With a loud crunching noise Izuku screamed out in pain. But as he did Stain grabbed him by the mouth, muffling his screams.

Raising Izuku high, Stain slammed the speedster face first into the ground with a crack of yellow lightning.

Gasping for air and with blood running down his nose, Izuku laid on the ground in agony. "Every step you take, every breath you take, every movement you make. I know it all. There's nothing you can do that I can't see coming. Those hits you got in before, I let you have those."

Feeling his rage build up inside him Izuku clenched his fist, got up, and let out a battle cry and began to rotate his arms creating a vortex.

Debris was sucked into this vortex as it headed towards Stain. But as it reached halfway another vortex hit, canceling each other out. "It's like I said Izuku! Anything you can do, I can do it too!" Yelled Stain.

"Oh yeah! Then see if you can keep up with this!" With green lightning sparking around him Izuku began to speed up. Soon it appeared as if a copy of Izuku was standing next to him. But it wasn't done yet, the copy then made another copy, then another, and another. Soon it seemed as if there were 16 different Izukus on the battlefield.

Mei and Bakugo who were getting into position for their plan were surprised to see this. "What the hell! Since when can he make clones!?" Asked Bakugo.

Mei shook her head, "They're not clones, more like an illusion created by moving super fast. But if Izuku could do this then that means…."

"Stain can as well." Said Bakugo. "Come on, we need to get this done. The longer we wait the higher the chance one of them dies. Hey half and half you ready?"

On the ground Todoroki nodded, "Ready." he said holding a spherical device.

Mei then chimed in, "Remember poor everything you got into that thing."

Back with Izuku, his clones were running at Stain trying to attack him. But as soon as one got in close Stain would thrust his hand forward killing them. "This is just a waste of time Izuku! You're only delaying the inevitable."

"Then try and find me." Said the clones all at once. "By the time you do, I'll find an opening."

Stain smirked, "You underestimate me Izuku. I already know which one is the real you."

Running in, Stain aimed for a clone with his hand vibrating, Izuku flinched and moved back. Stain's hand sliced Izuku's side causing blood to splatter.

Thanks to this the clones all disappeared as Izuku stumbled back clenching his side. "Like I said, I know every move you'll ever do." Said Stain wiping the blood from his hand.

"Then how about mine!" Yelled a loud voice from above. Izuku and Stain looked up to see All Might come crashing down in between them. "The both of you will stop this at once!"

"All Might? What the hell are you doing!? Get out of here, you'll only get in my way." Said Izuku furious that All Might would even show his face.

"I can't do that, right now my only priority is making you stop this nonsense. The only way to do that is to take him down." Said All Might, turning his attention to Stain.

"You stop me? Please, you can't even touch me." Boasted Stain. "But I on the other hand…" Running at All Might, Stain suddenly appeared in front of the number one hero. "Could kill you right here right now."

Stain was about to pierce All Might's heart when from behind Izuku appeared and tackled him away. The two went tumbling towards the ground before getting up and facing each other. "As much as I hate you right now All Might, I don't want you dead. But if you stay I won't be able to keep you alive for long." Said Izuku.

"Yeah I know, but I've been in the hero game a long time so I've learned a few tricks." Explained All Might pressing a button on a remote.

Just then a beeping sound was heard beneath both speedsters, both looked down to see a small flat circular device. But before either of them could tell what it was, the device suddenly popped.

This caused four light ropes to wrap around both of their arms and legs, pinning them in place. "The both of you are fast, but at those speeds you tend to lose your surroundings." Explained All Might.

Izuku tried to break free but found that he couldn't and he knew exactly who made these. "Damn you Mei, even now you're getting in my way."

"You're wrong Midoriya. Mei is helping you, you are just too blind with rage to see it. After we secure Stain you will be coming with us." said All Might as he approached Izuku and Stain.

But as he got closer the number one hero stopped in his tracks when he felt a cold shiver run down his spine. Izuku felt it too and turned to Stain, the aura around him was suffocating with murderous intent. "Y-You dare, you dare! No one chains me up! NO ONE!" Just then yellow lightning began to fall all over the city as Stain used everything to break out of his chains.

With Mei, her tablet suddenly began to fire off warning signs. "Oh no…."

"What's wrong?" Asked Bakugo.

"It's Stain, the energy he is giving off now is growing and building up inside him. All that built up energy has to be released somehow. But that could level the city." Warned Mei. "We need to get Stain away from here, now!"

Izuku also recognized what was going on and turned to All Might, "Let me go! There's no time to explain but if you don't let me go now we'll all be dead!" Yelled Izuku.

Sensing the desperation in Izuku's voice, All Might pressed the button and released him. Izuku ran at Stain to get him out of the city but as he approached he knew that it was too late. "Shit! Come on think Izuku, think. I need to contain the energy somehow…"

A millisecond later Izuku got an idea. Running towards Stain once again Izuku didn't grab him, but instead began to run circles around him. All Might watched as a massive tornado formed, "What is he doing?"

"He's creating a vortex with his speed." Said Mei. "If he runs at just the right speed the kinetic energy from his vortex should be able to absorb it."

"Can he do it?" Asked Bakugo.

"I don't know. We never tested anything like that. But if it's Izuku, I know he will." Said Mei. "Todoroki, you ready?"

With Todoroki, the area he was standing in was covered in a sheet of thin ice. The air practically froze as he poured his ice into the sphere he was given. With his icy breath Todoroki nodded, "Ready, just tell me when."

Mei looked over to Bakugo who nodded, "Toss it."

With all he had, Todoroki launched the sphere into the air. Just as it was about to fall it suddenly changed course and flew towards the sky.

In the air Mei used another one of her babies to pull the sphere towards her. Grabbing it, Mei felt that it was cold to the touch, "Is it enough?" Asked Bakugo.

"If I did everything right. It should be. Now we have to wait for an opening." Explained Mei.

With Izuku, his plan was working somewhat. The energy given off by Stain was slowly being absorbed but it wasn't enough. "He's still going to take the whole city with him. I'll just have to kill him before he does!" Said Izuku as his eyes burned green with power.

Closing in the vortex, Izuku was close enough to fire off a massive barrage of punches at Stain. With each hit lightning crackled inside the vortex, "This ends now you villain! This is for my dad!" Yelled Izuku as he stopped running and stood a few meters away. Taking a deep breath Izuku ran at Stain and pulled back his fist, preparing a kill shot.

Mei saw this and knew that the time was right, "Now Bakugo! Do it now!"

Grabbing the sphere Bakugo used everything he had and with a massive explosion threw the sphere down towards the ground.

The world slowed down around Izuku as he was now a few feet away from Stain. 'This is it! I'm finally going to kill him!'

But as his fist was inches from Stain, the villain suddenly looked up. "You call me a villain? How dense."

A loud KRAKOOM! Was heard as a bolt of yellow lightning came falling down on top of Stain. The resulting explosion was enough to throw Izuku aside, level several more buildings, and shake the land for miles.

When it was all said and done, and the dust settled, Izuku laid on the slope of a crater, his costume almost completely burned off. All Might fared no better as he was thrown and knocked out, and was now bleeding from his head.

Mei and Bakugo didn't get hit as badly, they were high enough and behind enough cover that it simply knocked them over.

But the city was in even worse shape than it was before. "My god," said Bakugo as he looked over to see a crater about 200 meters wide and 100 meters deep.

Mei slowly looked over as well and saw the carnage. "And this was a scaled back explosion. If Izuku didn't do what he did, we wouldn't be here."

Bakugo looked around, "Where is Izuku anyway? And Stain for that matter."

Mei used her quirk to zoom in and look around. A few moments later she spotted Izuku lying on the ground, "He's alive. As for Stain, I don't know."

She looked around for him but couldn't find him at first. But as she looked near the center her eyes widened, "I-It can't be…."

"What is it? Is Stain still standing?" Asked Bakugo.

Mei's lips trembled as she spoke, "I-I can see him. I can see who Stain is."

Bakugo was a bit confused, "We already know who he is."

But Mei shook her head, "This Stain isn't the one we know. I-It's….."

Hearing the name Bakugo's heart sank, "N-No, you're wrong!"

"I wish I was." Said Mei. "But I'm looking right at him. This Stain, the Stain from another world is…"

Down on the floor Izuku was slowly opening his eyes, his vision blurred as he looked around him. That's when he heard some footsteps, looking down towards the center of the crater he could barely make out the outline of someone.

Slowly making their way towards Izuku was a very injured Stain, his suit torn, his arms bleeding, and his mask was starting to flake off. "No one has ever pushed me to this point. Not even my world's Izuku. But you, you are different aren't you." Said Stain as half of his mask broke off.

"You were right, that other Izuku was weak, I see that now. He couldn't kill me, but you, you can kill me. So go ahead, kill me!" Yelled Stain as the bottom half of the remaining mask broke off.

Izuku struggled to push himself off the ground, sitting up, his eyes widened when he saw who Stain was. "Y-You…"

"Surprised?" Asked Stain as he stepped up to Izuku. "The other you was surprised too."

The final pieces of the mask Stain had on broke off. As it hit the ground the wind blew causing dust to be picked up. And in that wind Stain's ash blond hair blew, his red sharp eyes pierced into Izuku's very soul.

Stain smiled as he saw the look of despair in Izuku's eyes. "Yeah, that's the look I was looking for. What now Deku? What's your next move?" Asked Stain, who looked exactly like Bakugo.

"Kachan? No, this has to be some trick!" Yelled Izuku as he forced himself to his knees. "Who are you!"

Stain smiled, "It's me Deku, your best friend since we were kids. The friend who you forgot about. The friend you abandoned. The friend who let everyone special in my life die!"

Izuku was shocked, "T-This doesn't make any sense. Mei told me…"

Stain cut in, "The truth. I was a hero and a damned good one. Life was good, "

Bakugo, Unknown Earth

"Hey mom, I'll be there soon." Said Bakugo while on the train. "Should be there in 5 minutes."

On the other side of the line Mitsuki smiled alongside Masaru. "You better hurry up kid, your girl is going to eat everything if you don't hurry up."

Standing beside his parents was a girl with fawn colored hair and brown eyes. "Hurry up babe! We've been waiting forever."

Bakugo smiled, "I'm going I'm going, just hold on. Still don't know why you guys wanted to eat at a restaurant."

"What do you mean, it's the perfect place. You are just about to graduate from UA. Of course we are going to celebrate." Said Masaru.

"Thanks guys. Oh, the train is pulling into the station now I'll be right over." said Bakugo as the doors slid open.

As Bakugo got off the train a sudden explosion rocked the station. Looking around he saw that it came from the east, "What the hell? Is someone fighting?"

That's when Bakugo got an alert on his phone, warning that the Green Streak was currently fighting a villain. "Deku? He's fighting….Hey mom, I got to go, seems like the nerd needs some help."

"Then go kid, just make sure you catch this guy." Said Masaru. "We'll be waiting right here."

"Cool, see you in a…" but before Bakugo could finish that sentence screams were heard from the other side of the line. "Mom, Dad, Camie! What the hell was that?"

More screams were heard from the phone as Bakugo began to run towards the restaurant. Ripping off his clothes he revealed his hero suit underneath, "Hold on guys, I'm on my way!"

Firing off explosions behind him Bakugo made it to the restaurant, landing in front of it he ran in. But just as he was going to enter the door something green slammed into the side and went right through the restaurant.

As the green bolt of lightning passed through an explosion erupted from within the restaurant. The blast sent Bakugo flying back several meters before slamming against a wall. Bakugo was temerparly knocked out as a result but woke up a few short minutes later.

When he opened his eyes and looked around he found the restaurant where his parents and Camie were reduced to rubble. "NO!" injured Bakugo pushed himself up and limped towards the rubble.

Climbing on top of everything, Bakugo desperately searched for his parents and girlfriend. Stone after stone he lifted and threw them aside. After some time Bakugo came upon Camie, her lifeless body on top of Mitsuki and Masaru, she had tried to shield them. Looking down at them Bakugo suddenly heard the sound of cheers coming from several blocks away, and one name. "Izuku! Izuku! Izuku!"

This pissed off Bakugo, how dare they cheer his name when Izuku was the reason why his parents and girlfriend were dead. Izuku went to UA as well, he should have known what to do. He should have known that at his speed that he needed to be more careful. But he didn't, and now his mistake cost the lives of the people Bakugo loved the most.

In a fit of rage Bakugo used his explosions and headed towards where Izuku was. A few moments later he found Izuku standing atop of a building waving at the cheering crowd.

Clenching his fists Bakugo snapped, 'People are dead, and he's out here waving! He took my mom, my dad and Camie away from me and he's smiling! Fuck you!"

Using his explosions Bakugo launched himself towards Izuku. Izuku saw it but thought that Bakugo was going to congratulate him. But much to his surprise, instead of a hello, or a hi. Izuku got an explosion to the face. "You killed them! You bastard! You killed them!" Yelled Bakugo as he fired off explosion after explosion.

It took the intervention of other pro heroes to get Bakugo off of Izuku. By the time it was all said and done Bakugo, not Izuku, was thrown into a cell.

Being still a student technically at UA Bakugo was expelled from the school and wasn't going to graduate. As for Izuku, at the time he was working under All Might and was given permission to fight. Since All Might was still an influential person he managed to get Izuku off with a lecture. The casualties were nothing more than that, just casualties, it just happens.

Bakugo was devastated, he had just lost his family and his career. Walking down the streets of Hosu City Bakugo found himself in an alley. As he walked through a voice called out to him. "It sucks doesn't it, hero."

Bakugo turned but didn't find anyone. "Who's there?"

"Someone who wants to help you." Answered the voice.

"Help me? I don't need anyone's help." Said Bakugo.

"Oh but you do. You see it now don't you. The injustice in the hero world, you saw it first hand after all." Said the voice, now closer.

Bakugo gritted his teeth, "Deku…."

The voice now appeared to come from the wall, "Think about it. He's the one who killed three people and he doesn't get any punishment. But you on the other hand, did nothing but react and were given a much harsher sentence. The only reason you are out was because he pitted you. Where's the fairness in that?"

Bakugo thought about it, "There is none! Everyone I cared about is gone, but, but if it wasn't for Deku. This wouldn't have happened."

"And now you are a nobody. While he still becomes a hero, such a shame. But I think we can both help each other." Said the voice. "I can see it in your eyes. You want revenge don't you? The justice system failed you, but there are other ways to get what you want."

Bakugo flinched, "You mean hurt Deku?"

"Hurt him the same way he hurt you. An eye for an eye." Said the voice. "True punishment for his actions."

Bakugo hung his head as he thought back to the times he spent with his parents, with Camie. He thought back to a time when he trained to be a hero. He thought about how he got punished while Izuku, who inadvertently killed three people received none. It wasn't fair, how was any of this fair?

Looking back up Bakugo had a face full of determination. "True punishment."

"Excellent. You finally see it my way." Said the voice.

"Who are you anyway?" Asked Bakugo.

Appearing from the light was Stain, "Someone who knows what you're going through. Now, let's get to work righting what is wrong."

Back With Izuku

"And that's how I met Stain, my world's Stain. After taking me in, Stain taught me how to fight like a villain. I then took out those who wronged others, until finally I was ready to take you on." Explained Stain. "But the first time we fought, it didn't end well. You killed my Earth's Stain and I barely managed to escape. It was then when I decided that Bakugo was no more, I became Stain, the hero killer."

"Y-You, you, you bastard!" With blood spurting out of his wounds Izuku pushed himself, got up and tackled Stain. "I'll kill you right now!"

Raising his hand up Izuku began to vibrate it at super speeds. He threw his hand down but stopped just inches from Stain's chest.

"What are you waiting for Izuku, kill me." Stain then looked at Izuku's face. "I see, you can't do it can you. You thought I was just some random nobody. But now that you've seen my face, you can't kill someone with your best friend's face! What a coward."

Gritting his teeth, Izuku had every emotion running inside his mind right now. But as he was thinking of something a yell was heard. "You bastard!"

Izuku turned to find Bakugo, this world's Bakugo rocketing down towards them. "Die!" He yelled as he flipped in mid air and pointed his hands right at the two speedsters.

Both speedsters tried to get out of the way, but as they jumped back the explosion happened right in front of them, knocking them both back.

Stain slammed up against a boulder, but as he looked up Bakugo appeared once again. Grabbing Stain's face he fired off an explosion that had so much power behind it that the boulder shattered. "How could you! You took everything away from him!"

Stain slid again before stopping, walking over Bakugo lifted Stain up from the shirt and with rage filled eyes, stared into his own soul. "Why didn't you use your quirk? Do you think speed is enough to stop me?"

"Yes actually, my speed would be more than enough. But the reason why I haven't used those ridiculous explosions is because I can't. Once I took Izuku's speed I found that I could no longer use it." Explained Stain. "Now, this might be a bit weird but it's time I get rid of this weak version of myself."

Stain raised his hand and was about to stab into Bakugo but just as he was Izuku ran in and snatched him way. Stopping on top of the crater Izuku looked at Bakugo, his face was on the person who killed his dad.

Feeling the air around them thicken Bakugo tried to speak but was cut off by Izuku. "Get out of here and take All Might with you." He said dropping the number one hero beside him. "You're just getting in my way."

Izuku turned to leave but as he did Bakugo grabbed his arm, "Please, Izuku, don't be like him."

Pulling his arm free, Izuku ran back down into the crater. "Even after seeing who I was, you still chose to save him. I'm impressed, not many would be able to do that." Said Stain.

"He's not you." Said Izuku.

Stain laughed, "Oh but he will be. One way or another he will grow to hate you. And right when you think there's nothing wrong, he will betray you."

Izuku narrowed his eyes, "You think showing me your face has changed my mind. You're dead wrong, in fact now that I know who you are only makes me even angrier!" Green lightning began to spark out from Izuku's eyes as his anger grew once again.

Spitting blood onto the floor Stain smiled, "Don't count me out just yet Izuku. Just like this world's me, I will stop at nothing to best you."

Mei watched on as their plan failed, the sphere she had built was gone. It didn't even make it to the ground, "Hatsume, come in!" It was All Might.

"All Might! Yeah, I'm here. Are you alright?" She asked. "The device, it was vaporized before it even activated."

"Damn it, do you have a back up plan? But yeah I'm fine, just hurt. I don't think I'll be able to get close again." Asked All Might.

Mei didn't, "No, that was our only shot in stopping them. There's nothing more we can do." Just then more green and yellow lightning came crashing down around everyone. "They'll kill everyone!"

"We have to do something, anything. We can't let these two destroy Japan over this." Said All Might, as he dodged falling debris.

"We have to snap Izuku out of his rage." Mei then began to think. "I got it, but I need to get down there."

All Might nodded, "We are counting on you Hatsume."

Making her way down from her position, Mei clenched her fist. "I'll just have to talk you out of it. If not, I still got one more trick up my sleeve." Literally up her sleeve a blue device began to charge up.

AN: Dun Dun Dun! Did you guys expect it to be Bakugo? That other world Izuku is a really shity person. Take a guess on how this is going to play out. Now onto the announcement, as some of you have already seen, I posted that my other two stories that I have been writing have been on hold. Due to me having to take care of my mother who is going through chemo right now. Some of you may not care what I'm going through and that's fine, you don't have to care. I just want you guys to understand why this chapter was super late to update. Sadly, I really struggled in writing this chapter, it was slow, kept rewriting it, and just didn't like how I was writing in general. But I don't want to stop writing, I love to write. I already put two stories on hold, I don't want to do it to this one. So, I'm giving myself one more chapter. I'll write, see if I write better, and if I can somehow find a rhythm again I'll go at it. But if I can't I'll put this story on hold unfortunately. Again, some of you probably don't care, but it is what it is. I'm sorry, that's all I can say I'm sorry. In the meantime please be safe, especially with all the craziness that's going on with the two countries currently at war. I'll see you all in the next chapter.
