The Candyman is a drug lord in Keystone City. Working with Blacksmith's Network, he enlisted the aid of Chillblane to help protect his operations until Captain Cold (just about the only Rogue not working for Blacksmith at the time) attacked his establishment to get back at Chillbane for murdering his sister.  The Candyman decided to let the villains work things out for themselves but warned Cold that he didn't want to see him ever again.
The Candyman's brother, Joey, is one of the Flash Rogues known as Tar Pit.
