Batman has, since his 1939 introduction, stood tall in Gotham as the worst nightmare of the city's criminal underworld. Tackling threats that range from organized crime to gimmicky super villains on a crime spree, the Dark Knight has cultivated a reputation as a terrifying creature of the night who need only be feared by criminals. The hero has a history of donning suits of armor to face some of his enemies, which has left some wondering why he doesn't suit up regularly.
