Origin
Born to a life of disadvantage in a Florida slum, Waylon Jones was cursed with a hideous hereditary disease which gave him a tough scaly skin and reptilian appearance.

Suffering abuse at the hands of family and school mates, Jones became a bitter habitual criminal spending his adolescence in and out of juvenile institutions.

After a stint in prison he found employment as a carnival sideshow wrestling alligators where he was billed as the "Killer Croc."

Leaving the carnival Jones disappeared into the criminal underworld, until resurfacing in Gotham City as an extortionist for the Squid.  When the Squid attempted to unite the Gotham crime families, Jones murdered him and took control himself as the Killer Croc.
