Bruce Wayne (Earth-1)

Bruce Wayne protects Gotham City as the vigilante, Batman.

The Dark Knight
Throughout his early years as the Dark Knight, Batman has come across several villains, such as Bane and Killer Croc. He has also recruited a sidekick in Robin.

Batman VS Killer Croc
Jim Gordon requested Batman and Robin's help in taking down Killer Croc. This wasn't the first time Batman had fought Croc, and so he found it easy to track him down. The duo fought Croc through the city, from Ace Chemicals to the sewers. There, they discovered that Croc had been consuming the same steroid that had turned Bane into the monstrous figure he had become. The Venom served no use however, as Batman and Robin managed to defeat him once again.
