Dick Grayson is the sidekick of Batman, who helps him protect Gotham City as the vigilante, Robin.

The Boy Wonder
Dick Grayson was adopted by Bruce Wayne at a young age, and eventually began fighting alongside him as his sidekick, Robin.

Batman VS Killer Croc
Jim Gordon requested Batman and Robin's help in taking down Killer Croc. They managed to track him down to Ace Chemicals. The duo fought Croc through the city, all the way 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.
