Midoriya the lustful hero

birth of an incubus

Hello everybody this is the first fanfiction I've posted online. I have a few other fanfictions I wanna post online. Some crossovers and some in universe ones. I've added characters from other anime into this. I'm not sure who I'm gonna pair izuku up with seeing as his attitude may be a mix of the sweet little cinnamon roll with the epic badass Spike Spiegel. He may have a bit of a flirty side when his incubus instincts take over. Okay enough of this, enjoy my story. Disclaimer I don't own my hero academia or any other anime characters. 

Midoriya the lustful hero

Chapter 1

Usually when quirks manifest its at the age of four. Like his friend Katsuki Bakugo who could make explosion come off her hands. Izuku wanted more than anything to be a hero and have a quirk like his best friend. But it didn't happen when he was four. The doctor his mother took him to was a moron talking about extra joints in the toe. Inko stated that her uncle was a powerful elemental type and he only had one joint. So Inko midoriya decided to take her baby to an old friend of hers. Six year old Izuku had the hood of his all might hoodie pulled tight so his mother wouldn't see the scorch mark that kaachan left on the back of his neck from her deciding to use her quirk to tag the tiny greenette. When they got to a large office building the rode the elevator up to the fifth floor. Inko opened the door and inside was a small waiting room which was empty save for a purple haired girl and her mother. The girl was around Izukus age and she was reading a magazine and had aux jacks hanging from her earlobes. She had one of them plugged into her music player and was bobbing her head to the beat. At the desk by the other door was a black haired woman around 22 years old. She smiled at Inko and said. "Inko-obbachan how are you? Oh my goodness is this little Izukun!? Hello sweetie I'm shizune. I'm sure you don't remember me. My sister Midori and I babysat you when you were smaller. Oh she'll eat you right up if she sees you. I'll tell mother you're here. Miss Jirou Midori would like to talk to you before seeing kyouka." She titled her head speaking to the woman behind the midoriya family. Izuku blushed deeply at the affection and said softly. "I remember you a little. Your sister used to hold me too tightly." He saw shizune nod her head and turn as she heard a noise and say. "Oi shinra don't break that! It's brand new!" Izuku saw her eyes change and pulled out a notebook sitting down beside the girl. He drew her picture then began to write everything he could figure out about shizune's quirk and started to mutter. "Her quirk seems to be X-ray vision which is good for a doctor's office. But I wonder how long she can hold it before her eyes hurt and how far her X-ray can go." He flinched when he was poked in the neck and saw the girl staring at him. "Whatcha writing mumbles? A diary?" The girl said as one of her earJacks moved back to her. "Ummm no, it's my hero journal. I was writing down nurse Shizune's quirk and what it can do. Umm can I ask what your quirk can do? From what I can tell it's a sound based quirk and you can use the jacks on your ears to listen to things. I'm sure if you were to utilize a special speaker you could shoot out blasts of sounds using your earJacks." Izuku said as he flipped to a new page and drew a picture of the girl and what he observed of her quirk. The girl dead panned and poked him again with her earJack. "My name is kyouka Jirou and my quirk is called earJack. What you're saying is weird if you haven't known me. Did you get that just from observing me? Is that your quirk? Analysis?" She said as she noticed his hero notebook again. She blushed as his picture of her was amazingly good and very flattering. Izuku blushed and said softly. "Not that I know of. My quirk is weird. I can um make people do things like make them sad or happy just with a thought. I have these bumps on my head and one right here." He pointed to his tailbone and blushed as he realized he just pointed at his butt. Jirou giggled and said. "Well that doesn't sound weird that's pretty cool if you ask me. With enough control you could make villains stop fighting." He nodded and said. "It's hard for some reason my quirk works easier on women though. Whenever I ask my mom to make katsudon for dinner she says yes and my Aunty Mitsuki always hugs me when she sees me even though I told her I'm too big for that. I also noticed that most of my teachers give me good grades until I noticed I did not do as good as I should... I don't know that's why we're here today to see the doctor. She's an old friend of my mom. My mom told me she worked with recovery girl." Then Inko walked up and said. "Okay Izukun say goodbye to your new friend the doctor will see you now." Izuku smiled and said goodbye as jirou's mother came out to get her daughter. Inko handed their phone number to her saying how well they got along and to set up play dates. As they went into a typical doctors office a blonde woman was sitting behind the desk in the corner while a black haired young man with blond streaks was setting up the medical table. "Good morning Inko it's so good to see you." The woman said as she stood up. She was wearing a white lab coat over a grey scrub top and black Lycra pants and heeled sandals. The young man was wearing a similar labcoat over a dark blue shirt with a blue haired scientist saying 'it's showtime' along with black pants and sneakers. "Hello tsuchan, it's good to see you too. Hopefully we can figure out izukun's quirk. At first I thought he had a telepath quirk because I could hear his voice telling me it'd make him happy to have katsudon, it compelled me to do it be he said he could make people smile and I saw him say be happy to a crying woman and she smiled and kissed his forehead. Also he's got bumps forming on his head and above his bottom." Inko said softly blushing a bit not wanting to repeat to tsunade that he also unknowingly made people aroused and made an entire train car of women have orgasms just by smiling as he got on board and saying hello to them. Tsunade sighed and said. "Well I maybe have figured it out. His quirk is similar to a former pro hero called Lilith. Her real name is Ageha Kurono. I've already spoken to her about Izuku and she has agreed to speak with the both of you. She has a daughter a year older than Izuku and said she'd be willing to train him alongside her daughter. Kuronosan's quirk is called succubus. As the name implies she has the powers of the mythical creature. Flight, mind snaring, body modification. The list goes on. But Izukus quirk is the male equivalent. An incubus. Which is what I've labeled his quirk as. Here's her information so you can give her a call. The reason I think that Izukus quirk hasn't manifested is something I can't explain which is why my son is here. He's the one who found the similarities to Kuronosan's quirk. Shinra please explain then you can give Izuku the tests." Shinra stepped forward from his spot leaning against the exam table and smiled at them. "Hello Inko-obachan. It's nice to meet you Izuku. Okay so from my research on the pro hero Lilith is that her abilities are mostly mind control and pheromones she emits through her skin, her sweat, blood and saliva. From what I've read Izuku has a high pheromone count. The pro hero midnight has a similar ability of releasing pheromones through her skin but hers produce a sleep state. Now Izuku I'd like you to try and make my mother happy. Just be your sweet self like you did on the train." He said patting the young greenette on the head and giving him a kind smile. Izuku hopped off his chair walked up to tsunade who looked at him with a calculating expression. Izuku took her hand and could feel all the stress and unease in the blond woman. He didn't understand it but he tried explaining it. "I feel her emotions right now I think. She's stressed and tense about a girl named Midori. The name and face appears in my head. I'm gonna try now." He looked up at her gave her his biggest hero smile and said.  "No reason to be sad anymore, because I am here!" He gave a little cheer and tsunade and Shinra saw his eyes change purple for a second before they turned emerald again. Tsunade could feel all of her stress and tension melt away and a smile appeared in her face. Her face reddened as she realized she was getting aroused as well. Shinra chuckled and said. "Okay now can you sit up on the exam table? I want to see if your horns, wings and tail are sprouting yet, so please take off your shirt and pants please." Izuku nodded blushing a bit as he took his all might hoodie and his shirt and pants off. He sat up on the table as Shinra put his hands on the side of Izuku's head. He rubbed his thumbs against the bumps before moving down to his back where he saw a tattoo like image of small bat like wings where his wings would form from. He made a hmm sounds before he saw a small point poking from above the boy's bottom. He said softly. "Okay Izuku I'm going use my quirk to accelerate your incubus genes a bit." He then put his hands on Izukus shoulders and a silver aura surrounded them. As the aura encompassed Izuku, two curved horns grew from the boy's skull. They were about an inch and a half long and were black with bits of emerald green flecking. His wings popped out in a puff from the tattoo. His wingspan spread out longer than his arms. He groaned a bit as his tail formed curling around his body stopping at a foot and a half. Shinra fell backwards his mother sliding her office chair in place for him. He took a breath and looked at Izuku who hopped off the table and was looking in the mirror. He blushed and his wings wrapped around him like a cloak and his tail wrapped around his wings like a belt. Shinra took a chocolate bar from his mother and quickly ate it. His body looking less pale as he took pictures and measured the incubus quirked boy. He then said to Izuku, "okay now I want you to will your wings to disappear. Just think of yourself without your wings." He nodded to Shinra and in a puff of smoke his wings disappeared. Shinra let him put his clothes back on before Izuku decided to try something. He willed his wings to existence and the appeared his clothes automatically adjusting holes for them. He folded them up and smiled as he slowly got used to his new appendages. The adults looked at the boy in awe and Shinra wrote down information. He said to the midoriyas. "Now make sure that Izuku has a good diet and like any body part he has to train his wings before he can fly for more than a few seconds. I'd recommend signing him up for classes with a friend of mine. His name is Yue and he helps young winged quirk users get better with their wings. He was kyōdaina tenshi the angelic hero and now spends his time teaching. Also I'll have a list of martial arts Izuku should learn. He has the ability to change his body composition and make long claws like Lilith did or even turn his arms into blades. Now please if anything changes feel free to contact us. Please see shizune on your way out." Tsunade stepped over and hugged Inko and patted Izuku on the head handing him a chocolate bar which he took with his tail dropping it before picking it up again. Tsunade said quietly to Inko. "Shinra has books on body composition and what things are made of. I had shizune gather them up so Izuku can study them, he has a powerful quirk so make sure he uses it the right way. Call me if you need anything." Inko nods leads Izuku out of the office. Shizune hands books in a black bag to Inko who takes them before signing some paperwork. As they leave tsunade and Shinra stare out the window. "What did you see in his heart mother? With a quirk like his being a hero will be a long shot. He'd be better working as a police integrator or even a bodyguard for a celebrity. He could even become a rock star as I did amp up his natural talents a bit too. I figured he'd need the jumpstart." The blonde woman had an impassive look on her face as she looked at her son a grin forming. "He'll become a hero. He's got that spark I've only seen a few times."
