Michael got blind from an acid spill, his scars and marks all over his grey dead eyes as he uses a blindfold to fully cover them up. The acid enhanced his other senses leaving him only blind. He is like a bat, moving through places using echolocation especially in the dark, his other occupation was an assassin, and he is a professional at it. No one knows about his other occupation as he keeps it a secret, who is gonna expect it was a blind janitor? Main weapon, throwing knives.
