A quick explanation of what happened: Bakugo’s friends-- wingboi, finger dude, and others --jumped izu and basically beat him bloody. The also had gotten their hand on sharp weapons and then continued to damage both eyes to the point of blindness. Why did they do this? They thought it would impress Bakugo. Secretly, it didn't impress him. However, he didn’t want to seem like he cared for him. When the incident happened, the kids said that they saved izuku from a villain attack but not before being blinded.
This could be the origins of a villain izuku, or just the history of a very angsty bakudeku fic. Thoughts? Opinions? Criticism?
