Let's be honest. The Joker, Lex Luthor and Loki are all evil and bad and stuff, sure. But they ain't got shit on the monstrous depravity of some of the scum we've got walking among us everyday! I speak, of course, of the supervillains that hide in plain sight.
Meet the vilest of the vile, the scum of the earth, the villains that threaten our existence every step of the way.
