"Izuku!" - Flashback Dialogue

Chapter 1:Izuku's Origin!


"HA HA HA HA HA!" A young, strong-looking woman said as she climbed out of a pile of rubble, carrying multiple injured people. "What!? She's laughing!?" An onlooker cried out of shock."Everything's alright now. Why?" The woman said.

"Because I am here!"


For as long as I can remember, I've wanted to become a Hero. To save people with a smile on your face, saving them with no fear. Just like All Might, the Number 1 Hero. She is the Symbol of Peace, deterring all evil. She brought about an era of justice and peace. A true Hero… but… there's just one thing I didn't mention. Only women could be heroes. They are the only ones that can have Quirks due to them being the only ones able to "unlock" a certain gene that gives them Quirks. Men cannot. Even with this fact, many men have tried to be heroes using methods such as technology and martial arts, though, it won't beat natural powers.

Quirks. They are essentially superpowers. The first one appeared when a baby in China started glowing brightly. Afterwards, many more Quirks were discovered. Scientists, of course, studied these Quirks and how they come about. They discovered a gene simply referred to as the Quirk Gene. They found out that everybody has this gene, but women are the only ones that are able to "unlock" it. Meaning they are the only ones able to get a Quirks. It is quite strange, but no scientist has been able to figure out why.

Oh, uh… sorry. I forgot to introduce myself. My name is Izuku Midoriya. Though my childhood "friend" calls me Deku. I'm 13 years old I am 5'5". I have dark-green spiky hair and green eyes. I'm very skinny and plain-looking. As I've mentioned, my dream is to become a Hero… but, I am a male. I cannot get a quirk. I've been told by doctors, classmates, teachers, and even...even my mom and dad that I could not become a Hero, no matter what. Because of my dream, I constantly get bullied by all the girls in my school and the boys just ignore my existence. Despite that, I still kept on going. I won't just give up, that's not how a Hero would act, especially not All Might.

"Oi, Deku!" A girl shouted at me. "Stop dozing off into space you fucking idiot!"

Speaking of bullies, that's Tatsuki Bakugo, or as I call her Tacchan. She is 5'7". She has ash blond spiky hair and red eyes. She sits behind me in class and she was my childhood friend, but now she is my bully. She became my bully when she got her Quirk. I guess all the praise that she has gotten throughout her whole life got to her head and gave her an ego like no other. I can't blame her though. She is really powerful.

"Oh… sorry Tacchan," I said in a low, nervous voice. After Tacchan called me out, the whole class laughed at me. Before Tacchan yelled at me, I was working on the 13th volume of Hero Analysis for the Future, my journal series that contains my analysis of many heroines and their Quirks.

"All right, all right. Settle down class," my teacher said to the class. This got them to stop and get back in their seats and look towards the teacher. "Now, all of you girls are going to apply to U.A High School's Hero Course next year, right?"

"YEAH!" All the girls, except Tacchan, shouted in excitement while showing off their Quirks.

"All of you girls are dumbasses! I can't believe you extras would even try to be in the Hero Course with me! I will be the Number 1 Hero and I will surpass All Might!" Tacchan declared to the class.

A girl replied, "Man Bakugo-chan, your attitude is why people don't like you."

"I don't give a shit, so shut up! The teacher then looked at me, ignoring Tacchan's outburst, "Oh, Mr. Midoriya. Are you still going to apply to the Hero Course at U.A?"

I wish she didn't ask that, because now the whole class is staring at me, some girls were giggling mockingly.

"Uhhhh… I… ehhhh… y-yes?" I replied nervously. The girls started to laugh at me and mock me while the boys just stared at me in pity. Tacchan, however… "Ehhh? Why the fuck are you still trying to be a hero Deku? You're a boy, moron, you can't get a Quirk no matter how hard you try. The fact that you're still trying really pisses me off. Applying to the Hero Course is going get you killed, idiot. Plus, it's a Hero Course, so they probably won't even look at your application dipshit."

"Well… the thing is… It's always been my dream to save peo-"

"Just, shut up you idiot!"

"Now, now Bakugo. Just be quiet and sit down, please. Oh, and Midoriya?" My teacher asked.

"Yes, Miss?"

"Meet me after school, okay?"

"Okay Miss."

"Good, now onto attendance!"

After school finished, I went to my Homeroom teacher's class. I already have an idea on what she wants to talk about. When I came up to the door, I knocked.

"Come in," my teacher said. I opened the door and saw the classroom. I looked out the window and saw that the sky was a bright blue color and the sun was shining brightly in the classroom. I walked up to my Homeroom teacher who was sitting at her desk at the front of the room. All of the student desks were empty and abandoned. Some of those desks were strewn about which showed that school had only just ended. When I walked in the room I look to see my homeroom teacher working on some paperwork. She was a young woman with fair skin and a small beauty mark on her chin. She had long and straight brown hair tied into a ponytail. She also wore thin-framed glasses that stood on the bridge of her nose.

"I think you know what I want to talk about. You applying at U.A's Hero Course."

"What about it?"

"Look. I've already told that you won't be able to apply there. You are a male and you have no Quirk. They won't let you in. Plus, it's too dangerous and I don't want you to get hurt. You can still apply to be a police officer or firefighter if you want to help people. Also you're a very intelligent boy, so you can definitely apply to a prestigious high school and go many places."

I've been told this many times by my teachers and my mom and they're right. I've even told myself this many, many times to convince myself. I could be a police officer and arrest villains that a heroine stopped. Live a normal life where I go to a good school, graduate, get good job that pays well, find a beautiful women, marry her, have children, and die peacefully of old age. A normal life. It sounds nice, but… why does it make me feel empty and hollow?No matter how many times I tell myself it would be fine, I know it wouldn't be. Not at all.

"I understand." I replied.

"I care about you, okay? You're a good kid."

"Goodbye miss."

"Goodbye remember what I've told told you, okay?"

"Okay."

I walked out of the classroom and walked towards the exit of the school. In the center there is a large water fountain that has a walkway that circles it. As I made my way towards the fountain, Tacchan called out to me from behind, "Oi, Deku."

"Y-yes Tacchan?" I replied. I turned around to look at her as she was walking towards me.

"Stop trying to be a Hero, Deku. It's pointless you fool. You'll get get yourself hurt and I don't want to deal with your parents annoying me about your safety and stuff."

"Sorry… Tacchan. Its just that I-"

"I already know what you're gonna say Deku, so shut it!"

"But…"

"You know what? You really are just a dumb, blind, and annoying boy who won't ever actually see reality for what it is."

"…"

"What? Not gonna say anything?"

"… I can't gi-"

"Shut up!"

She shouted at me, enraged. She then raised her left hand up to. As she was lifting it up, her hand had little explosions coming off it. Then she smacked me with explosion which pushed me right into the fountain. I noticed that the explosion was weaker and smaller than the ones she normally hits me with, strangely enough. I was soaked in the fountain's water and so was my bag. As I got up from the fountain, I thought I saw a glint of a tear coming from Tacchan as she looked at me, but I'm sure I was just seeing things.

"Man, that burns," I groaned as I got up from the fountain. When I got out of the fountain, I shook my body to get some of the water of of me. I looked inside my bag to see that all of my things, Including my Hero Analysis for the future Vol. 13. I decided to look at my reflection in the fountain and I saw myself with a small burn mark on my face. Maybe she's right… maybe I shouldn't be a Hero I thought. She has a point. I'll never get a Quirk and I am being a blind fool. I felt so weak and empty on my way home. It hurts to even think about it, but she's kinda right. The truth is, I'll never get a Quirk. No, wait, what am I thinking! I can't just give up on my dream! I realized. With a new resolve, I took to a tunnel to get I was taking a tunnel walkway home I saw this large… thing at the end of it. I didn't know what it was, so I walked to in curiosity. As I got closer I was able to see what it was. It was mass of very dark green sludge with large, sickly yellow eyes and a large unhinged mouth with sharp teeth.

"Oh… a boy. A useless vessel," the sludge mass said in a raspy voice.

I looked at this sludge creature in pure fear. I just stood there with wide eyes, frozen in fear. This was clearly a villain, which meant that I could do nothing until a Hero arrived.

"Whatever. I shall have fun killing you then. Hehehehehehe HAHAHAHAAHAHAHAAA!"

"Wait N-!"

The sludge then pounced at me, covering me in its disgusting slime. It wrapped one of it's sludge tentacles around my neck, choking me. I couldn't breathe at all. It was suffocating. I tried to get it off me, but I was powerless. I couldn't get it off me. The slime was way too slippery and no matter how hard I pulled, my hands would slide right off, I desperately tried to reach my hands out for something, but everything around me was going dark.

"Please… help… me…" I strained out in desperation.

"There you are Sludge Villain!" I heard a voice shout. All of a sudden an intense gust of wind blew towards me and I was set free from the Sludge Villain's grasp.

"Ergh! Damn it! It's you, All Might!" The Sludge Villain shouted after it recovered from the blast.

When I got up I looked to see a tall woman with shoulder length black hair wearing a small ponytail and short bangs on her forehead. Her eyes were steel grey. She had smooth skin with a small mole on her right cheek. She had lean and defined muscles with very noticeable abs, and she wore a black skin-tight sleeveless body suit with a white, flowing cape, yellow gloves, yellow boots, and a red cloth being held by a gold, triangle-shaped buckle. She was smiling widely. I instantly recognized who she was.

"*gasp* All Might!" I shouted in excitement. I knew I was safe when she arrived to the scene. Saving people with a smile, like she always does. I just couldn't believe she was here, saving me! All Might then pulled her fist back.

"Don't worry. Why? Because I am here! Texas Smash!" All Might shouted heroically. All Might then punched towards the Sludge Villain. The punch was so strong that a gust of wind completely blew the Sludge Villain into many tiny pieces.

"Wow…" I gasped in pure amazement at All Might's power.

"Hey, young man. Are you okay?" All Might asked me.

"Y-yeah. Thank you so much All Might. You're so awesome! Can you please sign my book! I'm a really huge fan of yours!"

"A fanboy, eh? Of course, kid. I'm just glad your safe. Now I must apprehend this Villain and send her to the Police."

All Might signed my book and then started collecting the pieces of the Sludge Villain into an empty soda bottle she found on the floor. She put the bottle in her pocket. As she we was about to leave, I remembered something that I've wanted to ask her for a long time now. That question.

"Uh… All Might… I have something to ask you…"

"Hm? What is it young man?"

"This is a question that I need to hear the answer to from you."

"Tell me young man."

"Can… can I b-become a Hero, even though I'm a b-boy?"

When I asked her that question, she had this look of shock on her face. I don't know why she did. Then out of nowhere, there was a sudden puff of smoke that covered her. After the smoke cleared, I saw something that would shock me right down to the core. I saw a woman that was very skinny-essentially just skin and bones. She had the same hair and hairstyle that All Might had but her face was deep and sunken. She was slouching and her skin was somewhat wrinkled and old.

"AHH! WHAT'S GOING ON! WHO ARE!? WHA-" I shouted in confusion and fear.

"Hey! Keep it down kid." the strange-looking woman replied to me. "It's still me, All Might,"she replied to me reassuringly. Then all of a sudden she started spitting out a lot of blood from her mouth. This made me freak out for a bit, but I calmed myself down after a few minutes.

"What… what happened to you? How is it still you? Why are you like… this?" I asked after my freakout.

She looked at me with apprehension, which meant that this was a sensitive subject. Then she eventually sighed and started to talk.

"Okay kid, what I am about to tell you is highly classified information that you cannot tell a single soul. Not your friends. Not even your family. Do you understand?"

"Yes."

"Okay." She lifted up her costume and she pointed to this very nasty scar. It was a very sickly purple and took up a large chunk of her torso. I was so shocked to see that scar. What caused it? A villain? When did this happen? These thoughts and many more were flowing through my mind at a million miles per second.

"This was caused by a fight that I had with a villain a while ago." She explained.

"Was it Diabolica? Or was it Shark Attack, or was it…" I kept in mumbling about the possible Villains that could have done this to her, but she eventually cut me off.

"This fight was not shown to the media. The only people who know about it are the ones who were there to see it…"

"Whoa…"

"Ever since that fight, my powers have been weakening. My power now only lasts for about 3 hours per day."

"Wait, so you only have a limited time each day to work!?" I asked while recovering from the shock of the information.

"Yes. Well I've told you enough, I'll be going now." She said while turning away, about to leave.

"Wait! Don't go yet! You never answered my question…" I exclaimed to her. She then stops and turns around to look at.

"Oh yeah. Well kid… I'm sorry, but you can't become a hero. It's too dangerous for a boy. You could always become a Police Officer or a Fire Fighter…"

Her too? She's saying the same thing… I thought in pure devastation. My idol, saying the one thing I didn't want to hear. I was about to shed a tear, but I held it in. It's true. I really can't become a hero… I should've known. I am a boy after all. How could I become a hero? I guess Tacchan was right about me. I am just a stupid, blind, fool.

"I… I understand…" I replied shakily.

"Okay. I'm glad you understand. Remember, young man, it's okay to dream big, but it also has to be realistic. Now stay safe."

"Okay…"

All Might left, most likely to bring that Sludge Villain to the police. I still stood there trying to recover from the pure devastation of my hero crushing my dreams. I felt nothing. I then absentmindedly started to walk home feeling like a hollow shell. I kept on walking and walking feeling like the world around me had been destroyed into nothing. After walking for a bit I ended up in a crowd that was surrounding something. I heard someone in the crowd say something about a villain and I instinctively moved in to see.

Wow… I instinctively ended up at a villain attack place. It seems I still can't let go. I thought emptily. Though my mood had changed when someone mentioned that the villain was holding someone hostage.

"Oh my God! She has a girl hostage!" After I heard that I actually decided to pay attention to the scene. It was a scene of pure destruction. Cars turned over, fire spreading everywhere, destroyed street signs and broken windows. Everything was in chaos. I then saw that there were Pro Heroines at the scene. Some of the Heroines there were Kamui Woods and Mt. Lady (A new Heroin who made her debut yesterday). Then I look to the center where the villain was. No… It can't be. It's the Sludge Villain. How? Did she escape somehow? I thought to myself. Then I realized something. Wait… wait… she probably escaped when I was talking to All Might. She wasted her energy on can't power up and none of the other Heroes have the Quirks to stop her. All I was doing as I realized this was looking at the scene in complete horror, knowing that this is all my fault. I'm sorry… I'm so, so sorry All Might… Someone will come to help, I know it. A real Hero will come soon… Then I see who the Sludge Villain has hostage. It was Tacchan! She was trying to break free from the Sludge Villain's grasp. She looked like she was struggling to breath. Then her head turned towards the crowd and I saw her eyes. She had this look of pure fear. When I saw that look, I did something that would change my life forever.

I ran. I ran and I ran.

My body just moved on its own. Everyone was shouting at me as I ran. They were telling me to stop. I kept on running. Why am I running!? Why can't I stop!? I thought While running, my mind was a million miles a minute trying to come up with a plan to free her somehow. Wait a minute! I have an idea! I need to make the Sludge Villain flinch to release her! With my quick thinking, I threw my backpack at the Sludge Villain causing her to release some of her grip on Tacchan. Tacchan herself broke free somewhat and was able to breath. I want up to her and tried to claw her out of her sludge prison. I desperately tried to get her out, but the sludge was to slippery to claw through. As I was trying to free her she yelled at me. "WHAT ARE YOU DOING IDIOT! YOUR GONNA GET YOURSELF KILLED!"

"I… I DON'T KNOW! I JUST… MY LEGS STARTED MOVING ON THEIR OWN!" I shouted in return.

To be honest with you, I don't exactly know why I did that. "Sorry boy, you should've known that it's poitnless" "You really think they're gonna let you, a boy, in U.A?" "Ugh, I really do hate boys like you…" "This is why boys are useless!" "I'm Sorry Izuku… I'm so sorry." "She's the greatest Hero ever!" "It's to dangerous." "Tacchan!" Maybe it was the look on her face….

"I couldn't just stand there and watch you die!" I said to her while smiling as best I could with tears in my eyes. After that the Sludge Villain regained herself and raised a tentacle up high in the air.

"Alright then you little shit. I guess I'll just have to kill you!" She said. At that moment, I thought I was gonna die. So I braced myself for my impending doom, but something happened! All Might herself, all powered up, came in and protected me! As she defended me she told me, "I really am pathetic, aren't I? I told you what it means to be a true hero, yet I couldn't even live up to my own standard!"

When she finished her little talk with me, she grabbed both Tacchan and me and pulled her fist back to attack.

"Detroit Smash!" She exclaimed. She then punched with all her might which caused a large gust of wind. The wind blew very hard into the air which actually caused the sky to clear up and change the weather entirely. Everyone was cheering loudly as the Number 1 Hero saved the day once again. After All Might let go of me and Tacchan, some of the Heroines came to me and scolded me harshly after that stunt I just pulled. They were telling me that "I was being an idiot" and that "I could've gotten myself killed while trying to save someone in vain". On the other hand, Tacchan was getting all sorts of praise from the other Heroines for "bravely handling the situation" and "enduring the pain". Man, even if she was a victim in a hostage situation she still gets praised. It seems no matter what she does or what happens to her, she gets love and praise. Though to be completely honest with you, I did not mind at all. She was safe and sound, and that's all that really mattered to me.

After all the Heroines finished scolding me and praising Tacchan, I went home. By the time I was in a housing area close to my home, it was sunset. The sky was a warm, comforting orange with few clouds in the air making the scenery very peaceful and calm, the antithesis of the events that happened earlier today. I wanted to apologize to All Might but she was being swarmed by the reporters, so I couldn't get to him. I guess I'll just give her a message on her website. Just then I heard a familiar voice pull me out of my thoughts.

"Deku!"

"Tacchan?" I calmly replied in confused matter.

"Listen, what you did back there was stupid alright? You could've gotten yourself hurt, or, even worse, killed you fucking idiot! Even then, I was fine by myself anyways! You're just a boy who couldn't help anyone… You didn't help me. You did nothing." She then turned around and started to walk away. "I don't owe you anything… baka."

I was kind of baffled by this encounter. I could've sworn I saw tears in her eyes and that she was blushing the whole time. Seriously, what is happening with her today? Ahh, whatever. She is right though, I did not help at all there. Well… at least I tried. Now it's time for me to go back to giving up on my dreams. Just as I finished that thought All Might herself ran in front of me in her muscle form exclaiming, "I am here!"

I shouted in pure shock and surprise that she is here. I then ask, "All Might what are you doing her? H-how did you get of the reporters?"

"Hahaha! I stand for justice not soundbites. Because I… I am All Mi-" Then she suddenly turned back into her normal form spitting out blood.

"Agggh!" I shouted in shock. After she recovered, she then started to speak.

"Young man, I've come to thank you and also to discuss your question from earlier. If you hadn't told me your story… if you hadn't run into that fight, I would've been a worthless bystander watching from the crowd. So… thank you."

"N-no, wait! I was the reason she was there at all… I gave her the chance to escape… and I wasted your energy and your time…"

"I'm not finished. You are a boy which means you don't have a Quirk, so when I saw this timid, meek boy run in to save someone's life… a male of all people… it inspired me to act. There are many stories of Heroes and what made them great. Almost all of them have one thing in common… their bodies moved before they had the chance to think. Almost on their own…"

When she said that last statement I came to a sudden realization to what she's going to say. Then tears began to well up in my eyes. For some reason, at that moment, I remembered my mom's words in that moment, "I'm sorry Izuku…I'm so sorry…" I started to clench my heart and kneel down and I began to cry, because I knew what she was gonna say. The one thing I needed to hear.

"And today, that's what happened to you."

The tears I had began to flow and I clenched my heart even harder. I knelt down all the way to the ground. I could barely hold in my sobs.

You never told me mom… back then, the thing I wanted you to say. The words I needed to hear…

"Young man. You can become a Hero."

When she finally said these words, I couldn't keep it in anymore. I sobbed my heart out in pure and absolute relief and joy.

Dreams can come true.

Oh, by the way, I forgot to mention, this is the story of how I became the first and greatest Male Hero. The First Man.


AN: Hey guys, this is actually my first Fanfic. I've been reading stuff on this site for a while now and I feel that now is the time to start my own. This was influenced by the story called Alpha Hero by Saint Danielle and ever since I read that one I was just itching to do my own spin on it. So you've probably noticed that I got some of the lines directly from the show. It's not always gonna be like that though, so don't worry. The way I plan to do this is to follow the canon and change parts of it, big and small. So sometimes there will be lines right from the show (most likely only at the start), and sometimes there will be entire new plot points and events that change the flow of the story. That's the idea I'm going with. One thing I would like to say is that this story will begin at around a year before these events happened in the cannon. That means I am giving Izuku a year extra for his training. This will give him the chance to meet some of the girls before going into U.A. I would like it if you reviewed so that I can make my story better and maybe I could even get ideas. Also there may or may not be grammar errors in the story, if you could maybe point some of them out, that would be definitely appreciated. You don't have to point out the grammar stuff though. Also, yes this is a harem fic so, here is the list:

Ochaco Uraraka
