One week ago, Maro had gathered together a group of prostitutes from the streets of Gotham City deep under the nuclear power plant. They were to bear witness to the transformation of Waylon Jones. Already a criminal monster as the Killer Croc, Maro told Waylon legends of lizard men, urging the deformed man to drink from a bottle that he claimed was filled with virgin's blood. In drinking the fluid, Croc was transformed into an even more reptilian version of himself. The transformation complete, Maro encouraged the monster to feed on the kidnapped prostitutes.
