When your quirk revolves around causing chaos for the SCP foundation it certainly makes for an interesting life, especially when you add in the girl raised by Doctor Bright, 682 and 999 with a grudge.
When Katsuki Bakugou's bullying of Izuku Midoriya goes too far, the consequences are most dire...but Hisashi Midoriya won't accept them. However, the work solution he uses is rather...anomalous. The results are far more than expected.
Read note on the chapter.
Izuku was born pale and thin, his baby self's cries were lamenting and sorrowful. he had a rough start on life, that's for sure. but he would make a significant mark on the world, whether he liked to or not. (an scp-096 Izuku fanficiton, because i don't think there are any at the moment. first story, enjoy reading.)
