Riddler

Edward ‘Ed’ Nashton and later Nygma is the former butler for the Wayne family and a former forensic scientist working at the GCPD with a penchant for speaking in riddles. After killing a corrupt officer who worked there, Ed went down a path of criminal activity and became the extortionist, hacker and supervillain known as The Riddler. He was soon investigated by Batman and has since become widely regarded as his most intelligent enemy, hell-bent on proving that he is intellectually superior to the dark knight. Despite his frequent attempts, he is always outsmarted by Batman and this has sent him back to Arkham Asylum for treatment.Nygma has always managed to escape via any means necessary. The Riddler continues to challenge Batman. Overtime, The Riddler has not been taken seriously by the other members of Batman's rogue's gallery, due to his entire theme and gimmick being viewed as silly. So this has led The Riddler to try and pull off larger and more dangerous crimes. These include trying to frame Harvey Bullock for murder by forcing him to shoot random pedestrians.
