Gollum Gang Leader
Hello, my little pretty, pretty, pretty. You look good enough to eat." ―Golum Gang Leader to Poison Ivy

The Golum Gang Leader and his gang, the Golums, resided in an abandoned Turkish bath house, until Poison Ivy, with the aid of Bane, threw them out.

Behind the scenes

The Golum gang leader doesn't seem to be the similarly attired gang leader from Batman Forever. The relationship of their two gangs remains unclear. He was played by Doug Hutchison, who's notable performance was as Percy in The Green Mile.
