Corrosion of the Soul [Villain Izuku]

Izuku Yagi, a young boy that dreamed of being a hero, to save people just like All Might. That was...

Until he and his sister got the Quirk Test result. Quirkless. After that, things were never the same. His Father and Mother barely looked his way, talking to him only when necessary and ignoring his pleas when needed. His sister Izumi Yagi and his former best friend Katsuki Bakugo, berated, bullied, abused him, all because he had the thought of being a hero. Everything came to a halt when even his idol (and father), All Might, told him he couldn't be a hero.

Distraught, he couldn't take it anymore. He left, gone before any of his former family even realized. Unbeknownst to him however, a certain person was watching. Someone who saw potential in such a young mind, someone who could truly be a successor, someone who could break the Symbol of Peace. This man was searching for a successor after Tenko Shimura was saved by All Might before HE could get to the boy. What better than his own son he discarded.

Yes, he could see the boy's Corrosive Heart bleed out and bring all of Japan and Hero Society to Ruin. He just needed to take his hand...
