Izuku has the quirk of "crystal" where Izuku can change a part or all of his body into green emerald like crystal. The more he trains the more harder and more he can produce crystal. Izuku is a vigilante in this story until he gets caught by aizawa. He also gets one for all.

Izuku at the age of four got the quirk absolute electric control.

the boy named Izuku Midoriya what happens if he never admired All Might but somebody else? what happened if he admired stain the hero killer? follow Izuku Midoriya's journey to becoming a vigilante,becoming Stain's apprentice (I do not own the cover or any art used all credit goes to the rightful owner,I do not own my hero academia)

My first story, open to constructive criticism. Updates will probably be choppy, sorry! Art is not mine, unless I say so.

After being "abandoned" by his parents for being quirkless. Izuku had to put up with Tomura Shigaraki for months before he was rescued by some Pro Heros. After that day he was adopted by two Pros Eraserhead, and Present Mic. But he wanted to do something more, so he trained... hard, so that he could do good. So that he could become a Vigilante, and someday become a Pro Hero. ⚠️I dont own anything in this fanfic.

Izuku will be a vigilante in the beginning but will eventually be put on a rehabilitation programme. Izuku will still be quirkless but will be training since the age of 5 but will hide all of his muscles using baggy clothes so he won't be suspected. Izuku will have 'Adoptive Muscle Memory'. (The power to replicate movements after observation.) This is how Izuku was able to master a lot of martial arts in such a short amount of time. Izuku will just watch fights on certain martial arts as well as heroes to replicate and master their moves whilst minimalizing the amount of errors. Izuku will be using a lot of weapons and anyone who has encountered him has described him as a demon. This is mainly because he has the strength capable of killing a bear and the speed that puts a cheetah to shame. Include this in small areas where he can use the walls to increase speed and you got your self a deadly weapon capable to outmatch even the likes of All Might to shame. He got this strategy after watching Gran Torino use it and he was only able to watch him fight by hacking into cameras which he learned from watching it happen. (Okay, so Izuku's ability 'Adoptive Muscle Memory' also allows him to copy any action performed by others as long as he has seen it once even if it's on TV, this is really useful but isn't a quirk and it's just apart of his brain much like a photographic memory.)
