Ever since the first issue of DC's Batman '66 comic climaxed with an honest-to-Gotham airplane chase scene that ended in a fiery explosion, it's been pretty obvious that one of the goals of that book is to do things that they never could have done on the TV show. As much as the comic has captured the tone of the series, it's also made it a point to go bigger, throwing in bigger set pieces for the action, exotic locations and stories that literally go to new places that we never saw on the show. But there's one other way that the comic has been expanding on the show that's even more interesting than just pitting Gotham City's arch-criminals against a giant crime-fighting robot.
Over the past two years, writer Jeff Parker and a rotating cast of artists that includes Joe Quinones, Jonathan Case, Rubén Procopio, Sandy Jarrell and Giancarlo Caracuzzo have been introducing villains that never appeared on the show to the world of Batman '66, bringing pop-art takes of characters like Harley Quinn and Killer Croc to the comics. And they've been doing it in a way that's absolutely fascinating.
