And then there was Midoriya
In the world my hero academia 80% of the population have quirks. Quirks are superpowers and there are three categories transformation quirks, mutant quirks and emitter quirks. However our main character Izuku Midoriya was born as quirkless but still believed that he could become a hero even without a quirk. However in this story Midoriya get a device that changes his life for better or for worse depending on how he uses it…
It started a month before the sludge villain attack when Midoriya was coming home from school being bullied for not having a quirk when he heard his name being called, he went down the alleyway and was grabbed by a mysterious figure. He tried calling for help but the figure covered his mouth and slammed something on his wrist, the device then said "Omnitrix reset". "Damn it that wasn't meant to happen but this can still work." said the mysterious figure , the figure began to run off but not before saying one more thing "hey kid make sure that you don't use that Omnitrix in public unless your well hidden".
After Midoriya got his composure back he looked at the device that put on his left wrist by the stranger "so this thing is called the Omnitrix huh I wonder how it works. I think it would be best if I found out in private". When Midoriya got home get greeted his mother and made sure to keep the Omintrix hidden from his mother, when he got to his room and finally got to learn how to use it, after pressing the little button on the watch, the centre of the Omnitrix popped up he began to cycle through the silhouettes on the watch. He finally decided on one that looked thin and short, when he pressed the centre down and began to change and he became a short, thin, blue and black alien, "woah what happened to me my whole body has changed." Midoriya thought to himself. For nine minutes he learnt that this alien was able to run at extreme speeds and was able to do tasks that would usually take him about 10 minutes to do in a matter of seconds.
There was a knock at Midoriya's door and he realised his mother was going to enter his room, "Izuku are you ok in there, I heard some loud noises coming from your room a few minutes ago". Still being the alien Midoriya replied "yeah i'm ok it was just a video there's no need to come into my room", "Izuku your voice sounds very different are you sure your ok" replied Inko, Midoriya then said "I just have a dry throat that's all", suddenly the symbol on Midoiya's chest began to flash and started beeping "Izuku what is that noise." Inko said "it's just my ringtone mom no need to worry" replied Midoriya, Inko then said "Izuku i'm coming into your room to see what is wrong with you". As Inko opened the door Midoriya was hidden by a white and red flash turning back to his usual self, "see mom nothing wrong with me." Inko let out a sigh of relief and said "I'm sorry Izuku. Those sounds that were coming from your room were started to get me concerned." after this Inko leaves Midoriya's room and Midoriya makes a few notes about the alien he turned into before he goes to bed.
