Riddler Concept

Edward Nygma is a twisted genius who leaves riddles as clues at the scenes of his crimes. He operates under the name of Riddler and is one of the Batman's most well-known adversaries.
This concept nods significantly to Alex in "A Clockwork Orange" while retaining basic Riddler elements like the cane, eyemask, bowler hat, questionmark shirt and penchant for green and purple.
