Quirkless Izuku (Revamp)

Izuku's life wasn't sunshine and rainbows as most children have it. His life is filled with pain, suffering, mental trauma, as well as abuse from his peers. He lives his life as a meek, timid, shy young man who is deathly afraid of what anyone around him will do to him if he lets his guard down in front of them for even a moment. He had done that many times in the past and those around him had used his lowered guard to change their attitudes and turned on him on the moment that he showed them his true self. But what happens when he reaches his mental limit when being saved by the Number 1 Hero of the World All Might? What happens when he is attacked by a villain made of sludge and is saved by that man at the same time? What happens when this Hero makes him think about his life to the point of nearly giving up? Find out in this revamp of the original story that I have once told!
