Edward Nygma

a fastidious forensic scientist. Edward Nygma loves a good murder and Gotham always delivers. No matter how gruesome or grisly it gets, he is ready to slip into a pair of gloves and get down to the business of solving crime.*The Riddler is a super-villain enemy of Batman who commits crimes revolving around an obsession with riddles. His mental psychosis results in a deep inner need to prove that he's smarter and therefore better than others, which causes him to leave behind clues in otherwise perfect crimes. This psychological compulsion has resulted in him being repeatedly imprisoned in Arkham Asylum. Despite this obvious flaw, he is otherwise an extremely intelligent criminal mastermind.*
