Andre Le Blanc is a master thief and adversary to the Teen Titans. He's an arrogant Frenchman who bills himself as the world's greatest jewel thief, and advertises his crimes before they're committed. This leads to the consequences you would expect for someone who does that. Andre LeBlanc was created by Marv Wolfman, Len Wein and Bill Draut, first appearing in Teen Titans #18. (1968)
