Here with another new story. This is an AU where Izuku has a Quirk, which you will partially find out in this chapter. Rated for language, violence, lemons…even though this sickens me, child abandonment in this chapter, possible character death. OOC, character bashing and enjoy the first chapter.

4-year-old Izuku held his mother's hand as the two of them stepped into doctor's office. Inko walked up to the desk before she smiled down at her son, "Why don't you go sit down, sweetie and I'll sign us in,"

"Okay mom!" Izuku turned and ran towards the waiting room as Inko turned and signed the form in front of her before joining her son in the waiting room.

Inko looked down at her son with a concerning look crossing her face as he played with his All Might figure before the two of them heard a voice call out, "Midoriya!"

Inko slightly smiled as she stood up, "That's us, sweetie," Izuku smiled and nodded before he jumped up and followed his mother.

The two sat across from the doctor before the doctor turned and smiled at Izuku, "Ah, you must Izuku, am I right?" Izuku smiled and nodded, "Okay, so how this works is we're going to take an x-ray of your foot and then take a blood sample," Izuku hummed and nodded again, "You aren't frightened about that?"

Izuku shook his head, "No, I'm going to be a hero just like All Might and heroes aren't afraid of anything," Inko smiled as she ruffled her son's hair and the doctor chuckled, "Okay, let's do it!" he jumped up and followed the doctor into the other room.

Inko frowned as she shook her head, "I hope he gets a Quirk…I'd hate to see his dreams get shattered if he were Quirkless," sighing, she crossed her arms and patiently waited for her son and the doctor to return.

Izuku sat in a chair as the doctor brought a machine closer to him before turning out the lights and stepped behind a glass wall, "Okay my boy, you'll hear a slight humming noise, but don't worry. All I'm doing is taking a picture of your foot," Izuku nodded as he heard a high pitch whining coming from the machine.

The sound soon stopped, and the lights flickered back on as the doctor stepped out from behind the glass wall and walked over to Izuku, "Okay, and now I'll need to take a blood sample," Izuku smiled as he held out his arm, his hand clenched into a fist, "You're not afraid, are you?" Izuku hummed and shook his head as the doctor took a syringe and drew some blood.

Upon seeing the crimson liquid, Izuku's eyes widened as he quickly licked his lips, alerting the doctor, "Is…is everything okay, my boy?" Izuku hummed and looked up in confusion, "Are you okay? Is something wrong?" Izuku tilted his head to the side and the doctor asked a third time, "You were staring at the blood…are you okay?"

"Uh…I'm fine, doctor," Izuku smiled before looking about the blood again with wide eyes, "Can I have that?"

"N…no…we need to use this blood sample to see if you have a Quirk or not," Izuku frowned as the doctor shook his head, "Let's go sit with your mother while we wait for the results, okay?" Izuku hummed and nodded before jumping off the chair and followed the doctor out of the room.

Inko looked down at her son as he sat down next to her before the doctor cleared his throat and the two looked up, "Ms. Midoriya, would it be alright if I speak to you in private?" the two adults looked at the confused Izuku as the doctor shook his head, "It'll be okay, son…I just need to talk to your mother for a minute…you can wait in the waiting room,"

Izuku looked at his mother and Inko gave a soft smile, "Go on, sweetie. I'll be out in a minute," Izuku nodded before he stood up and walked out of the room, closing the door behind him.

Inko looked at the doctor as the doctor sighed and shook his head, "I don't know how to say this, ma'am, but…it appears your son has a blood-related Quirk," Inko's eyes widened as the doctor continued, "When I first drew blood from your son, he looked at the vile with a hungry glare behind his eyes, he then asked for it…as if he wanted to drink it,"

"B-but doctor, aren't blood-related Quirks…taboo? Villainous?" the doctor hummed and nodded as Inko frowned, "Are you sure? Maybe he was just playing an-"

"I'm sorry, ma'am, but it appears that your son will in fact have a blood-related Quirk," Inko shook her head, "Support his dream in becoming a hero…who knows, maybe he will be one of the few rare ones with a blood-related Quirk to become a hero," Inko ignored the doctor's words as she stood up and walked out of the room, closing the door behind her and the doctor frowned, "Poor kid…he wants to be a hero, but thanks to his Quirk, it'll be almost impossible for the world to accept him as one," turning around, he walked to the back of the room.

Izuku looked at his mother as she drove down the street surrounded by wooded areas, a hardened expression crossing her face. He frowned as he tilted his head to the side in confusion, "Mom?" Inko grunted in annoyance, "So…what's my Quirk?" Inko quickly hit the brakes, coming to a screeching halt before glaring at him in disgust, "M-mom? I have a Quirk, right?"

"You damn monster!" Izuku's eyes widened at his mother's tone, "You want to know what your Quirk is? Your Quirk is a villainous one…you can't be a hero!" Izuku felt tears build up as Inko stepped out of the car and walked around to the passenger side before opening the door, "Get out!" Izuku's eyes widened, "I refuse to raise a damn villain, get the hell out of my car!" Izuku frowned as he slowly climbed out of the vehicle.

Inko slammed the door shut before walking back to the driver's side and climbed back in before speeding away.

Izuku frowned as he looked around to see woods surrounding him on all sides, "Why did you get out of the car?" he looked back to see a man with long black hair, dressed in black, standing next to a woman with long purple hair, in a black and white leotard standing behind him before the man stepped forward, "We saw her throwing you into the car and we decided to follow to see if you needed help…but why did you get out like that?"

"Because my mom said I have a villain Quirk and I can't be a hero…she was mad," the two frowned as Izuku shook his head, "I don't know what my Quirk is and my mom called me a villain and a monster,"

The two adults frowned before the woman looked at the man and softly spoke, "Shouta…we can't just leave him out here…he'll die,"

"I know that Nemuri, but unless we know exactly what kind of Quirk he has…we don't know how he'll act an-"

"You'll be there to control him…besides, we have a friend who can tell us his exact Quirk, and…you know I can't get pregnant, and it could be fun having a kid around,"

Sighing, the two looked back at Izuku, "Kid," Izuku looked up and frowned, "My name's Shouta Aizawa, but you might know me better as Eraserhead, and this is my fiancée Nemuri Kayama, but you probably know her as the hero Midnight,"

"Hello," Nemuri smiled as she waved at the child and Izuku's eyes, "What's your name, sweetie?"

"I-Izuku…I don't know if I can say my last name anymore," the two frowned as Izuku looked down the street, "I just want to go home,"

"Well…do you want to live with us?" Nemuri asked and Izuku looked up in confusion, "We have a friend who can tell us what your Quirk is exactly and if you get out of hand, Shouta can use his Quirk to stop you…plus…I can't have kids due to an accident I was in a few years ago," Izuku tilted his head to the side, "We'd like to adopt you,"

Izuku stared at them as Shouta sighed and shook his head, "It means we would like to be your parents…unless you want to go home with your real mot-" before he could finish, Izuku quickly hugged their legs and rapidly shook his head, "Alright kid…let's get you home then," Nemuri picked him up before she and Shouta began walking down the street and Izuku rested his head on Nemuri's shoulder before closing his eyes.

The three sat across from a woman with blonde hair, pulled back into a tight ponytail as Izuku frowned and hung his head before Nemuri spoke, "So Asumi…do you think you can tell us about his Quirk?"

"After hearing what happened to him, I don't see why not," she looked at the saddened boy and gave a sad smile, "Okay kid…all I'm going to do is touch your forehead. You have to keep calm. Can you do that?" Izuku looked at Nemuri and Shouta and the two slowly nodded before he looked at the woman and nodded before she reached over and touched his forehead with her index finger and middle finger.

The two closed their eyes for a moment before the woman sighed and opened her eyes and stood up. Looking at the two, she slightly frowned, "Shouta, Nemuri…can I talk to you in the other room?" the two slowly nodded before they stood up and followed their friend into the other room, leaving Izuku scared and confused.

Nemuri and Shouta stared at Asumi as she took a deep breath, "He has a blood-related Quirk…similar to that of a Vampire," she looked at them and shook her head, "His hearing, strength, stamina and speed will all increase greatly as his Quirk develops, he will be able to shapeshift and of course…he will need blood every so often an-"

"Is that all?" Nemuri crossed her arms, "We'll be able to handle him. If he gets too out of hand, Shouta could just erase his Quirk for a bit an-"

"There's one more thing you should be aware of," Asumi warned, "If he craves blood and something prevents him from getting any, he will enter what I will call Bloodlust. He will attack anyone and anything he sees just to satisfy his hunger…even you two,"

"And like Nemuri said, we'll take care of it," Shouta sighed, "If he gets too out of control, I'll simply stop him with my Quirk…besides…his mother was going to leave him in the woods because of his Quirk…he's going to need people to guide him,"

Nemuri hummed and nodded as Asumi sighed, "Alright, you two are the heroes here, so I won't question your judgement, but I advise you to tell him about his Quirk as it develops so it won't scare anyone around him or even himself," the heroes nodded before they watched as their friend turned and walked out of the room and out of the house.

Izuku sat at the table across from Shouta with his head down, "Don't worry, kid," Izuku looked up and frowned, "Nemuri and I are still going to adopt you, despite your Quirk and we'll help you learn how to control your Quirk,"

"I…thank you," Izuku bowed his head, "Thank you,"

"No need to thank us," Nemuri stepped in with a faint smile, "We weren't just going to leave you there and I told you that I can't have kids because of an accident I was in, so…we'd like to adopt you, Izuku," Izuku slightly smiled, "Anyway, dinner will be ready shortly. Why don't you go and explore the house for a bit and I'll call you when it's done?

"Uh…o-okay…but what are we having?"

"Katsudon," Izuku's eyes widened and Nemuri slightly smiled, "I see you like Katsudon," Izuku nodded, "Okay, go play and we'll call you when it's ready," Izuku nodded again before he stood up and walked out of the room, Nemuri and Shouta watching him as he walked up the stairs.

Okay, here's the first chapter…I wanted to give him a different kind of Quirk, but halfway through with writing this something just screamed vampire…enjoy and please let me know what everyone thinks.
