I don't want to say Black Bat is the original Daredevil, because they way he was blinded and the way he sees is different than Daredevil. I won't say how (unless you want me too) in case you don't want spoilers.
I seen his origin in the Comic Masks in the store lol.
I never read Masks. I knew Black Bat was in it, but I had forgotten. Did it say how he got blind and about his eyes and how they work? I still say read Black Bat. You do know the series ended in May don't you?
