Errrr wha?.... But there are heroes and villains who doesnt wear masks. Reluctantly Vickers dug into the artsy basket and started to draw a face, poke holes where eyes should be, draw a line for the nose and poked a larger hole for the mouth. He was trying to make it look like Lex Luthor, but as he slipped it on it looked more like Dr. Doom's mask.

All he needs to do is to pull his robe's hood up and the costume is complete. That or look like a Deatheater....

Now as for the hero question. Up goes the hand "Professor there is Captain Marvel, he has similar powers to Superman in that he can fly and has super strength and invulnerability and has the power to call down magical lightning"

And then there was the villain part. Well the benefit of being somewhat force to make a mask for it, but which one now.... Up goes the hand again "Professor there's Lex Luthor, who is the arch nemesis of Superman. He doesnt have any powers like the Man of Steel but he is incredibly cunning and tenacious"
