Batman and the Killer Croc of Doom! (The Dark Knight Series)

When a whole park full of homeless people are kidnapped, BATMAN is called on to investigate. He discovers a trail that leads to the sewers, where he finds hundreds of mutated half-human, half-crocodile zombies — along with KILLER CROC himself! THE DARK KNIGHT manages to fend off the feral freak and escape, but gets infected in the process. He has 24 hours to find a cure, or BATMAN will become one of CROC'S reptilian zombies.
