The Cyclops

Why was the cyclops such a threat? He's only got one eye. He's got no depth perception.  When I was a kid I was a comic book nerd and liked the idea of a bunch of handicapped super heroes like No Depth Perception Man, but it's very impractical for a villian to be terrifying with no depth perception. Like he'll try to throw a rock at you but thentrip over a goat and FTP the rock on his toes. Or completely overshoot and hit the demon horde behind you
