Izuku Midoriya, a quirkless bound boy is constantly bullied by his former best friend Katsuki Bakugou, as you all know, but this is a story when a simple tussel is taken further than expected. Bakugou puts a bit too much behind one of his blasts when he is four years of age, a time when his quirk control was very limited, and it is aimed directly at Izuku's face, Katsuki looks on in horror seeing a massive red mark covering Izuku's eye as he screams in agony. This was not just a simple burn that could be somehwat healed in time, this was a scar that would stay on Izuku's face for the rest of his life. For the next year of Izuku's life, it was a living hell to put it bluntly. Everyone was either terrified by him, or disgusted by him. The only upside being that Bakugou never touched him again, not even interacting with him. But he was bullied and outcasted in his school, and every time someone mentioned his scar, or he looked in a mirror, he would be reminded of his weakness and failure. This would be the case for 3 more years, when at the age of eight, when became a possibility to him, thanks to a brunette who just so happened to transfer into his school. (Cover art not mine, without a doubt) This story will only get worse in time, don't you worry.

All Might find a homeless teenager with green hair and real heroic spirit and made him the next holder of One For All. Quirk Izuku strong but not OP.
