13 COVERS! Unless it’s the occasional “slice of Gotham” story, Batman these days only fights his city’s most notorious, horrific villains — a larger-than-life figure dueling other larger-than-life figures. The idea of having a Big Time Bad Guy every time out dates to the 1966 Batman TV show, with its villain-of-the week formula. For years before that, however, the Caped Crusader battled a litany of colorless thugs and malefactors, mixed in with the Joker, Penguin and Catwoman stories. But those fedora-wearing mobsters weren’t pushovers: They frequently got the jump on our heroes, even if, in the end, the Dynamic Duo always prevailed. The everyday crook made something of a comeback once Batmania ended, but by the mid-’70s, the Darknight Detective was increasingly menaced again by his colorful rogues gallery, as well as costumed pretenders. Today, almost every Batman story tries to be an opera of epic proportions, with the gunsels and gangsters generally relegated to cannon fodder. But let’s return to the Golden Age, when Batman and Robin were as likely (if not more so) to fight random gangsters as they were the likes of the Scarecrow or Two-Face — even on the front of the book.
