Fan Casting Master Jailer in Return to the DC Universe

A genius locksmith and inventor whose expertise for designing foolproof containment units for maximum security super-prisons made him a considerable fortune, Carl Draper grew bored with his talents in those fields, deciding to challenge himself by testing Superman in a series of traps himself that would even test the Man of Steel. Though he has tried to walk a different path, now with Checkmate under new leadership, Master Jailer is aiding Maxwell Lord and Amanda Waller, even if he's weary of them both.
