The Phantom

Summary

What if Izuku Midoriya had a Quirk but the Quirk was very dangerous and has a mind of his own but needs Izuku to survive. It grows by eating any living thing and gains something from it. But it also killed the only thing that Izuku loves and he will be blamed for it because it was his own Quirk. So now, on the run and scared of being labeled a villain, he might have to do things that a normal hero wouldn't do.

Chapter one

The birth of a Phantom.

Izuku Midoriya was only four years old when the doctor told him that he wouldn't have a quirk. So now hopeless, he watches his favorite video of All Might to help try and make him feel happiness again. While watching All Might save those people from a burning building, he asks his mother if he could be a hero, just like all might without any Quirks. She just hugs him and says, "I'm so sorry!"

One year later

Izuku now five years old was sleeping in his bed surrounded by his All Might merchandise including figurines on his dresser, posters on the wall that were covering the room. But that's when he wakes up to somebody typing on his laptop. So he slowly opens his eyes and sees a shadowy figure on his computer. Izuku, now terrified, focuses on not moving even trying not to breathe loudly but he was freaking out internally, not knowing how this person got into his room. His heart starts to race so much that he can literally feel every thump of his heart like it was about to burst out of his chest. But as he starts looking at the man closely it starts to show that it doesn't look like a man, but more of a monster.

The monster looks to be about six feet tall with long fingers they had sharp points at the end but not like nails but more like the fingers itself became sharp at the tips. It doesn't have any ears and doesn't look like that has eyes either. The mouth looks like an endless rows of sharp teeth with no lips. It also has horns popping out from it above where its ears should be. The horn twist at first but then become straight towards the tip.

That's when it speaks in a spine-chilling voice, "Oh good...You're awake now so we can have our little talk." The monster stands up and slowly started walking to Izuku.

Izuku freaks out and jumps off his bed while throwing a blanket over the monster. He then makes a beeline for the door. He attempts to open the door but he has a hard time turning it due to all the panic that's going through him right now.

The monster just stands there and watches. He notices a Izuku is struggling to open the door. He stands there just staring at him with an annoyed face. Well what a person could assume is an annoyed face due to the lack of what he has in that department.

Eventually Izuku is able to open the door and bolts through the door as fast as he can. Izuku then screams out, "Mom! Help! There's a monster in my room! PLEASE HELP PLEASE HELP PLEASE HELP!" Eventually Izuku got to his mother's door. But he looks back and notices the monster was following him slowly. Izuku quickly opens the door as fast as he could. But again, the door handle is hard to turn due to his panic while Izuku keeps shouting 'mom' to no reply.

Eventually he gets the handle on the doorknob to turn open and he pushes the door open. He then opens the door and turns on the lights but all he sees is red. And to his horror, he sees strands of green hair like his mother then he sees her in a pool of blood. He then sees pools of blood scattered on the walls, the floor and the ceiling. Seeing all this makes his stomach start turning. He then starts vomiting on the floor with tears going down his face. But he hears footsteps coming closer to him the wood creaking getting louder and louder.

He tries to move but his body was frozen, like if time stood still for only his body. Eventually he hears a step right behind him and it stops. He tries to turn his head but even his head doesn't respond. He knew that he was going to die and that he will be eaten next. He starts to think of somebody that would save him. He thinks of All Might saving him but he knows he wouldn't come. But still, he prays that he will give him strength to move but thinking about All Might saving the day, somehow gave him the power to move again. But the monster blocks the doorway so re rushes into his mother's room and steps into the puddle that was his mother, splashing him, he then looks for anything that he can use as a weapon to protect himself from the monster. He runs up and grabs a lamp from his mother's night table, holding it like it is the only thing keeping him alive. So now covered in his mother's blood and holding a lamp, he stares the monster down knowing that he's going to die, he does the only thing he can think of...He smiles like All Might always does when he goes into danger.

The monster stares at him for a bit then starts walking slowly towards Izuku. The monster stops once he reaches five feet away from Izuku and just stares at him. Soon, the monster speaks with a chilling tone, "All I want is to talk. I can't kill you so drop the lamp." He says while towering over Izuku is still staring him down while still hanging on to the lamp. The monster speaks again with a demanding tone, "Put down the lamp, we need to talk about your Quirk which is myself."

Izuku freezes when he hears those words. He shakes his head and then replies to the monster, "I'm quirkless...I don't have a quirk" The monster just points at his hand and Izuku follows where the monster was pointing. He then notices a black string coming from his finger that connects to the monster. His heart drops when he sees that making him drop the lamp, he looks at his hand that it was attached to and slowly brings it towards his face. He then shouts out in disbelief, "No! You're a liar! I don't have a quirk, I don't have a quirk! I'm just worthless, quirkless, Izuku..." That's when the tears start coming back in full force making it hard for Izuku to see.

The monster attempts to speak with a soothing voice but it comes off as more creepy, "Look. I know you're not going to understand this but I'm going to need you to listen. You do have a quirk and it's me, congratulations. When I was created in your sleep, I was more like a...mindless monster and I was hungry. I went to get food, which was your mother. After I ate her, I had become a lot smarter making me realize I just killed your mother." The monster bows apologetically to Izuku.

Izuku was processing the information. He slowly starts to have a panic attack from what he realizes and that he killed his mother. He realizes the monster is him. He realizes his Quirk is awful. He realizes that he shouldn't have been born. He realizes all of his hopes and dreams are gone. He realizes the only person he ever loved in his life is gone. He knows he can't do anything. He's just a monster a worthless and pathetic monster. He is a Deku. So now struck with so much panic, he passes out in the pool of his own mother's blood.

The monster just picks him some of Izuku's clothes, his toothbrush and a few toys. The monster then walks out of the apartment, carrying Izuku.

Bakugou Residence

Mitsuki Bakugou decided to visit her friend Inko, after driving Katsuki to school. So, she walks over to her apartment for one of her surprise visits. When she got to the door, she was shocked to find that it was already opened. So fearing for the worst, she dials 911 and tells them the address. After a few minutes of waiting, she musters up enough courage to open the door fully.

Once she looks inside and sees nothing out of the ordinary, she shouts out, "Inko! Are you here!? Izuku are you here!? Can somebody please answer me!? Izuku! Inko!" Not hearing anything, she starts looking around the apartment and during the search, she notices that nothing really looks out of place. Everything looks normal except for nobody being here. She sees the dishes from last night's dinner were still in the dish rack and they were dried already but she sees that nobody started cooking at all. Now she was getting more worried, the more she investigates. But eventually, she heads to Inko's room. She notices a picture of Inko right outside her door, so she picks it up and notices that there's dry blood on it. That just makes her start panicking so she opens the drops the picture in horror, from seeing what was left of Inko. She smells copper in the air from the pools of blood, that were dried now. She then falls to the floor weeping and soon she tries to muscle the strength to stand again but she just isn't able to get up. Then she thinks about Izuki and hoping that he was still alive. So from thinking that, she musters up enough strength to run to his door. She then runs up to the door and shoulder tackles it open. She starts searching the room with tears in her eyes and starts hyperventilating because she couldn't find Izuku anywhere.

She starts screaming for him, thinking that he was hiding from the killer, "Izuku! Where are you!? Where are you!? Izuku! Please answer me!" She runs to another room, "Izuku! Please respond to me! Where are you!?" Her voice is full of worry and fear while her body starts shaking. She now knows that he isn't in the house since she saw no blood in his room or anywhere else besides Inko's room. So she calls the police and while waiting for them. She starts searching the rooms again and again and again and again even though she's already searched the house because she would start losing her mind if she stood still. But that's when he hears the sirens indicating that the cops were near. So she heads outside and screams for them to get over here. The police arrive and they take her statement. After giving her statement, she goes back to her home, dragging her feet. She then opens the door and waits for her husband to get back from work.

After a few hours, Masaru comes back home and walks in then sees his wife crying, "Honey? What's wrong?" He says with a worried look on his face.

Mizuki whispers, "In-Inko w-was m-murdered..." She whispers this while she's crying on the floor with her knees up to her chin, trying to make herself as small as possible.

Hearing those words, he freezes for a second but then he understands what he had to do, he had to go to Mizuki and comfort her. So he wraps his arms around her and he looks at his wife lifting her chin up, "Everything's going to be fine, we'll get through this together, okay? Because I know she was your best friend." He says in a warm tone trying to make her feel better but there was a hint of sadness though because he knew that he had to be strong for his wife at the moment.

"Why did this have to happen to her!? She didn't deserve this! She was such a good person! She was the nicest person! Me and her were best friends! Why is she gone…? Why would anybody do this to her?" Tears start running down her face and she was holding on to her husband, squeezing as hard as she could that her nails starts clawing into his back. Holding him tight like her life depended on it.

Masaru strokes her hair and gently as possible then starts humming a tune to calm her down. Putting his hand between her hair stroking it ever so gently.

Mitsui finally chokes out the last thing, "Whoever did this...took Izuku as well." She then shoves her head into her husband's shoulder.

After about two hours, Katsuki arrives at home with an annoyed face because due to Deku not showing up, "That damn nerd!" He thinks to himself, "Ruining Heroes vs Villains! Because we had to wait for him and he never showed up! When I get my hands on him! I'm going to beat him up and then explode the heck out of him! Does Deku think he's too good to play with me now!? Is he looking down on me!? I will put him in his place next time I see him! I'll make sure he never forgets!" He stops thinking to himself when Katsuki notices his mother has a sad look on her face.

"Katsuki...We need to talk to you about...Izuku and Inko" She says with a sad tone in her voice.

Katsuki gets mad at this and starts thinking to himself, "That damn nerd! He told on me! So that's why you didn't want to play superheroes and villains with us! He was too busy crying to his mommy and told my mom that I keep beating him up! I guess that Deku had enough!"

Katsuki sighs with a grumble, "Okay Mom, I'm sorry, can I go get dinner now?" Saying with an annoyed tone in his voice.

Mitsui looks at her son, thinking of the best way to do this, "Should I just go straight forward? Should I be more gently? Honestly...I'm not really ready to do this. Maybe I should get Masaru? He's a lot better at this than me but I'm his mother and she was my best friend. I need to be the one to do this I need to tell him."

Katsuki looks at his mother with a worried look on his face. He's seen her mad but the way she was acting now, it's totally different. Katsuki starts to feel unsettled due to his mother's actions. So now he looks at her with a worried look on his face.

"Mom what happened?" He says

The moment Mitsuki hears that, she starts crying again and reaches out to hold her son as hard as she can while tears start running down her face again.

Katsuki was very confused and repeated himself, "Mom...what happened?" Now with a way more worried expression.

Mitsuki says in a faint whisper, "I'm sorry...I'm really sorry, Inko and Izuku are gone."

Katsuki thinks to himself that this couldn't be. Deku couldn't be gone. Auntie inko couldn't be gone. Why would they leave? He starts pushing against his mother and he creates a small explosion to get her hands off of him. Mitsuki yelps in pain letting him go. Katsuki then runs out the door, running as fast as his little legs can take him to Deku's apartment. He just kept running and running, ignoring everything else trying to get to what he needed to get to and that was Deku's apartment. He sees caution tape all around Deku's apartment. He then falls to his knees with tears in his eyes. He hears footsteps coming behind and he doesn't even turn to see the person. He just starts causing small explosions in his hands, slamming them into the ground while screaming. He keeps doing this until he couldn't cause any more explosions in his hands. After that, he feels some warm arms wrap around him with tears in his eyes so he turns to see the person that was holding him and it was his mom.

"I'm going to miss him too ..." She says while crying, holding him, trying to calm him down so he doesn't cause any more explosions.

The woods

Izuku slowly wakes up and sees that he was in a tent. He looks down and notices that he's in different clothes and there wasn't a drop of blood on him. He starts to think to himself that it was just a dream after all, thank god but then he freezes for a second noticing a black string coming out of his finger making him start screaming internally, "how do I get out of this!? I can't run away, he'll catch me!" Izuku's heart starts to pound, "How the heck do I get out!? If I'm able to fight him off! I can escape...no that's stupid! He's part of me! What do I do! What do I do! If I can't get out of this...it's over, I'm dead! No! He can't kill me! He needs me alive! That's right...I got to play my cards right! He can't hurt me! He needs me! But maybe I can seal him away but right now he's too strong…!"

"Come outside...Izuku..." The monster calls out with a malicious tone.

Izuku freezes when he hears that voice. He knew that there was no way he could run so he puts on his best All Might smile and then proceeds to crawl out of the tent. Izuku, with his All Might smile, goes to the monster and looks at its features. He sees that it was terrifying. The monster stood next to a campfire while sitting on a log, having a stack of books next to it and it was currently reading one. Izuku cautiously sit across from the creature on the opposite side of the campfire. The tension in the air was so thick you would need a chainsaw to cut it. The monster paid no mind to izuku. He just sat there, reading his book. Izuku stares at the monster wondering how he can read with no eyes. The monster just sat there for 10 minutes flipping through the pages. Izuku couldn't muster up the courage to say anything. Eventually the monster finishes its book and closes it then gently puts it in a pile next to him.

"Thank you for letting me finish my book." The monster finally says in a grateful tone. The monster then looks at Izuku, noticing that he was trying to stay silent while trying to put on a brave face. The monster makes a gesture with his hand signaling Izuku that he can talk.

Izuku struggles to say the words, "W-why a-are y-you do-doing this to m-me?" He finally says looking at the monster still with a smile like All Might.

The monster looks at him before speaking, pondering the question. After a bit, he says, "Honestly? It's for your own protection. I mean you killed your own mother with your Quirk even though it was by accident. What do you expect me to do? Not run away?" The monster's tone was in an indifferent, like it was just another day in its life.

Izuku shouts in anger from how the monster was trying to blame him for killing his mother, "No! I did not kill my mother! It was you! It was all you! I would never hurt her! You're the bad guy!" Izuku was shouting at the top of his lungs at the monster.

The monster looks at him calmly then says, "I am your Quirk…"

Izuku sits there looking at the monster realizing what he just said. He tilts his head to the ground and tears started falling from his face hitting the ground.

He then stands up and starts shouting with pain and sadness in his voice, "WHY ME! I DIDN'T DO ANYTHING WRONG! ALL I WANTED TO DO WAS BE A HERO! ALL I WANTED TO DO WAS SAVE PEOPLE! I NEVER WANTED TO HURT AN INNOCENT PERSON! I NEVER WANTED TO HURT MY MOTHER! ALL I WANTED WAS A QUIRK SO I CAN HELP PEOPLE!" After he screams, Izuku falls to his knees, breathing heavily with tears going down his eyes. He starts pulling his hair trying to wake himself up because he was thinking that this was a bad dream but soon stops realizing that that this was a reality. He falls onto the ground looking at the campfire and then he curls up into a ball and starts to sob quietly.

The monster stood there looking at the sobbing Izuku. then the monster said with a concerned tone, " If we're going to survive, we're going to need to help each other. That's the only way I see Both of us not being put in jail for the rest of our lives. " Then the monster walked up to izuku. Then the monster kneels down. putting a hand towards Izuku.

izuku doesn't respond. he thinks to himself, he looks at the monster. he decides to get up. He doesn't take the monsters hand. he looks towards the monster with a vicious glare. if looks could kill the monster would be obliterated. he stared at it and then he said. "Why do you care you already ruined my life. you said you're doing this to protect me? the only protection I need is from you. you are the one that killed my mother it wasn't me. you may be my quirk but I can't trust you and I'm sure as heck not going to help you." izuku said with all of his might glaring at the monster determination filled in his eyes.

the monster finally stood up, towering over the boy Looking down on him. he was staring at izuku's eyes looking at the determination in them.

Then the monster said " well I guess we should head to the police station then" he picked up a Izuku by the arm and started dragging him.

Izuku tried pulling away from him with no avail. then he started to pull His arm harder then he started to bite to no avail as well. izuku shouted at the top of his lungs "let go of me and why are you taking me to the police station?"

The monster grumbled with annoyance " so me and you could be locked away forever. you know since we killed your mother."

izuku shouted "I didn't do anything it was you." while he was still struggling to break free.

The monster let go of izuku's hand and then said " what's wrong I'm a bad guy I should go to the police station with my partner in crime and then turn myself in? Then your mother can rest in peace knowing the person that killed her is brought to Justice." The monster said in a sarcastic tone.

izuku fell to the ground shaking his head and then shout out " I did not kill her it was you. You're the murderer here. I didn't do anything wrong" tears started to form down izuku eyes

The monster shouted in anger " I am your quirk! no matter how much you want to deny me I am your quirk! That means I'm a part of you!Which means you're the reason your mother died! if you weren't born she would still be alive! if you didn't have a quirk she would still be alive! do you get it now you did this unintentionally but you did it! so if you're not going to help me then there's no point in me keeping you safe From being locked up in a prison cell!

izuku shakes his head blurts out " no it couldn't be me. I would never do a horrible thing like that. it's you." izuku starts shaking rapidly out of fear.

The monster looks at him and then says, "Look Izuku, if we don't work together. Your life is over and you will never be a hero but maybe if we work together, you can be a hero. The first step is accepting what you have done even if it was an accident. Do you understand?

Izuku thought about it for the next ten minutes weighing his options, the pros and cons. But soon, he stops shaking and picks himself up from the ground, trying to muster up as much courage that he can at the moment. Then he speaks, "Okay, I understand, I'm not in a good position but I want to make some ground rules, no more killing. "

The monster shakes his head and says, "No deal."

izuku shouts out with anger in his voice, "Why!?"

The monster replies in an annoyed voice, "Izuku...Do you know how your Quirk works?"

Izuku thinks for a second, then he says, "No, I do not know how my Quirk works. Do you know how it works?"

The monster nods then he kneels down to Izuku's eye level before he speaks, "Your Quirk is complicated, so you should just listen. First, I thought it was just summoning me until I started testing out what I can do. After I kill a creature, I gain these little resources. I guess you can call them souls. I don't know what they're called but I killed a bear on the way here. After I consumed it, I felt off, like there was something inside of me. So I started to mess with the thing inside of me and I was finally able to mess with it enough that this came out." The monster then pulls out his hand and a shadow like bear emerges but it was only one foot tall.

Izuku looks at the bear it looks like a stuffed animal and izuku feel slightly tired when it appeared. it didn't seem to have any features at all. except for maybe the claws. those were the most Bear Like.

Then the monster pointed at a tree. the shadow bear Moved sluggish. It started clawing at the tree stripping the tree of its bark. After about 20 seconds of it scratching. the bear disappeared. after it disappeared Izuku starting to analyze so he can have a much better understanding of his quirk and started to mumble.

The monster turns his head to izuku. then the monster spoke " my theory is this after I kill a creature I absorb its soul. after I absorb its soul I can Summon a construct of it. depending on how many Souls I put into it the Construct could be stronger or could be very weak. right now I've only killed the bear. maybe if I hunt more of them I can make this bear stronger and the duration is pretty shitty. now izuku you Try summoning the bear."

Izuku raises his hand he starts to focus. after about 3 minutes. he starts to feel something, he starts to pull it out. A small Shadowy bear appears but now it has a black string attached to it. izuku points at a tree next to the one that the previous bear attacked. this time the bear moves much faster. Claws went into tree way more vicious and A faster rate. the tree eventually loses a enough would that it collapses. After the tree falls izuku notices that he feels a lot more tired.

The monster says " Izuku if you're planning on Surviving this we're going to need to kill but I'm willing to only kill bad people that deserve it. no innocent Souls do we have a deal." the monster looking into a Izuku eyes not breaking eye contact even though he doesn't have eyes.

Izuku too tired to argue and understanding his position. Speaks " okay I understand that this is something that we need to do to survive. so I'm okay with that term as long as they're really bad. not like stealing. more like murdering bad okay." he spoke while making eye contact to where the monsters eyes should be.

the monster spoke "will speak about more rules later on. by the way I need a name."

Izuku thinks in his head for a minute then shouts. " I got the perfect name fluffy" After saying that Izuku giggled a bit.

The monster facePalm.. Then he ignored what izuku said. The monsters started mumbling to himself before speaking. " I got it Akuma. That's a good fit for me" The monster said with Glee.

Izuku said " doesn't that just mean devil" with a confused tone.

Akuma replied " I mean you just made a deal with the devil so I feel like it fits." Akuma chuckled after saying that line.

Izuku thinking to himself starting to regret his decisions but understanding it's the only one that he can do right now at the moment

Izuku stands upstrong raises one of his hands to Akuma.

Akuma sees this and and meets his hand.

izuku and Akuma shake hands. both understanding that they need each other to survive and if they don't work together they're going to die or worse.

Now both of them look towards the future uncertain where it may lead them.
