Demon of the hero world

My quirk!

(I'm gonna start this story from when deku was told he was quirkless except ya know he won't be because that's what I'm basing the entire story around and since I don't feel like going back and looking at what they exactly said in canon I'm gonna just make up what they say cause I'm lazy sorry) (also side note if any good photo editors would be as kind as to create a new cover for my what if story that would be awesome cause I kinda just threw this together I suck at making covers)

(Start)

Deku was sitting with his mother in the doctors office waiting to find out what his quirk was. He kept his head down and sat on his hands so that he wouldn't fidget. "Well doctor what is my little boys quirk? I know it's something good!" Inko asked in excitement for her own son "well it seems your son has a very interesting quirk with a multitude of different abilities and uses. One of the most interesting of the abilities from his quirk is his increased strength, stamina and speed which are just a few of the things he will be able to do at this point we are not able to fully pinpoint what all he will be able to do with his quirk but we can assume that he will have a lot of potential in the hero society if that is the route he wishes to travel down. We have deemed the quirk name demon art" the doctor explains to deku and inko.

Deku's expression immediately brightens as he hears the news his quirk is awesome. Deku can't wait to learn how to use it so that he can surpass all might and become the number one hero. "Did ye hear that sweetheart your quirk is amazing you can definitely become a hero!" Inko exclaims looking at deku with a smile on her face. Deku turns his head up at his mom with tears flowing out of his eyes. He had a huge smile and nodded "yeah mom I heard I'm so happy I can become a strong hero like all might!"

(Time skip 2 years)
(Age:6)

Deku was still unable to activate his quirk even 2 years after finding out what it was he tried so hard to find a way to finally unlock the power that the doctor said he would have. It all seemed hopeless to deku until one day he found two kids picking on a little kid who was completely defenseless "hey leave him alone!"  Deku yelled running in front of him holding his arms out to block the two bullies from getting past him. "Hey this is none of your business get out of the way wimp" the first bully said cracking his knuckles as he stepped forward a bit. "Yeah what he said you're to weak to stop us anyway" the second bully taunted as he punched deku in the jaw knocking him down. "AGHH!" Deku put his hand to his chin wincing as pain coursed through his body when he touched where the bully hit him. "That's what you get we told you to leave now we're gonna beat you up too" the second bully said laughing as he kicked deku in the chest causing him to keel over screaming "hahaha what an idiot this small fry really thought he could protect this nerd what a joke" the first bully said laughing along with the second bully. The first bully then went to kick deku in the stomach.

Deku was pissed at himself he was supposed to have a powerful quirk that he could use to save the day with a smile on his face like all might but it was all for not "why am I not even able to protect one person against some bullies I have a quirk don't I? A strong one then why can't I use it? I was supposed to protect everyone like all might I was supposed to be like my hero so why can't I even keep one person safe!?" Time seemed to slow for deku as his mind raced. All of his efforts came back with no results and he was starting to give up he could never be all might. Then it clicked he couldn't be all might they where different people. If deku wanted to be someone who could save the day he had to let go of the thought that he could be anything like all might "fine I get it I can't be all might I get it so to be a good hero I guess I'll just have to be someone who even all might would be afraid to fight I have to get so strong so that I can protect everyone but I can't do it by limiting myself like I have been. So I'll be the powerful hero that everyone is scared to fight so the villains won't dare hurt anyone anymore"

deku's twisted view on how he needed to be in order to protect people as the number one hero actually caused something to happen. A giant shockwave blasted forward at the boys knocking them back. They landed on the ground and scrambled to pick themselves back up. "What the hell you think you can hit us and get away with it we are gonna make you wish you had a real hero to come and save you" the second bully screamed getting in what a very small amount of people would consider a fighting stance. "Yeah you shouldn't have even tried fighting back we are to strong for a wimp like you!" The first bully said getting ready to charge at deku.

While the two bullies where rambling deku stood up and dusted himself off before looking down to see his shirt was ruined. He ripped it off and what he saw underneath shocked him. His skin had become pale almost to the point of being white and his small 6 year old body had not gotten any bulkier but it had definitely become slightly more toned. black lines had started forming, stretching from head to toe in an intricate pattern (he looks like akaza but with green hair and now green lashes) deku ignoring the two turned around and looked at the other kid "hey are you ok?" Deku asked calmly "y-yeah I'm fine but wh-what's with your body?"the kid asked worried for deku "I think it's because I finally awakened it." Deku said as an evil looking smile spread across his face "what d-did you awaken?" The kid asked shivering a bit at the creepy smile that suddenly appeared on deku's face "my quirk" Deku said as he turned around to face the bullies "hey don't ignore us asshole we're gonna kick your ass!!" The first bully said as he finally charged at deku.

Before the bully could understand what was happening he was knocked out cold on the ground "huh not such a big shot now are you?" Deku mumbled before turning to face the second bully "wh-what the how did you do that you where weak a minute ago and what happened to you" the second bully stammered backing up slightly with a frightened look plastered on his face "doesn't matter" Deku said before jumping at the bully kicking him in the chest "doesn't feel so good does it? No it doesn't but you still decided to do it to people who you thought where weaker than you and that is disgraceful." Deku walked up to the second bully and picked him up by the collar. He then punched the bully across the jaw and dropped him.

Deku turned around and walked back to the smaller kid holding his hand out. The smaller kid grabbed it and Deku helped him up "you're safe now" Deku said as he let go of the kids hand "thank you so much!" The kid exclaimed in happiness and awe of how strong this kid his same age was. "Yeah whatever get out of here" Deku mumbled rolling his eyes.

After the kid left he looked down at himself examining the pale skin and black lined pattern spreading everywhere on his body that he could see. He would have to check if they where all over his body later. "Hm guess this isn't going away. Well whatever it looks pretty cool" he said to himself chuckling.

Deku Walked back home. When he arrived inko freaked out over how Deku looked. "What happened to you izuku!!?!!" Inko yelled running over to deku with a frightened look on her face. "I did it mom I awakened my quirk!" Deku said hugging inko tightly. "That's amazing baby I'm so proud of you! The weird new patterns and pale skin are gonna be tough to get used to but it'll be fine it's not like it is a bad look." Inko said standing up. "Now you go get ready for dinner sweetheart." Inko commanded pointing to the bathroom. Deku nodded and walked into the bathroom to wash his hands.

Deku turned on the bathroom lights and looked at his reflection surprised. He definitely looked way different than he had just a few hours earlier. His face was pale and had the same black lined markings spreading over it. His hair was still green but it had become shorter, and his eyelashes had turned the same shade of green to match his hair. When deku looked at his eyes he was even more shocked. Inside his now yellow pupils read upper moon three, but that was not the only change in his eyes his Scalera had become a light blue with black lines fragmenting across it. His small body had become a little more toned as well as pale, and much like everywhere else on his body black lines spread over his chest and stomach in an odd pattern. Once Deku was done washing his hands he walked out of the bathroom to go eat.

Deku finished eating and handed his plate to Inko. "Alright Deku you've had a long day why don't you head to bed. "Ok mom love you." Deku said as he got up and pushed his chair back under the chair. Deku ran to his room and shut the door before hopping into bed falling asleep as soon as his energy drained body hit the sheets.
