Batman #489 1992

Batman #489, titled "Killer's Bane," finds an exhausted Bruce Wayne seeking medical help as Killer Croc rampages through Gotham. Tim Drake convinces Jean-Paul Valley to don the Batman costume for the first time to confront Croc. Bane makes his second appearance, easily dispatching Croc and realizing this Batman is an imposter. This issue is a crucial prelude to the iconic "Knightfall" saga, notable for Jean-Paul Valley's initial outing as Batman.
