The Riddler (DC Animated Universe)

"Do you know what happens to gate crashers? They have to match wits with the Riddler."

In Batman: The Animated Series,Edward Nygma was a former computer software designer. After losing his job, he became the supervillain known as The Riddler.He was voiced by John Glover.

Edward Nygma was a brilliant man, a genius in many fields, with an absorbing love for puzzles and games. As a computer software designer for Competitron, he designed "The Riddle of the Minotaur" a game that quickly became a smash hit. Competitron's sales soared, and several people became very wealthy, including Competitron's corporate chair Daniel Mockridge. However, Mockridge fired Nygma, callously dismissing Nygma's efforts as insignificant, and attributing the company's success to its skill with business negotiations and obtaining favorable contracts (i.e., to himself). In fact, Mockridge was attempting to give Competitron exclusive rights to the game, with an eye on a lucrative sale of the company.

Two years later, Mockridge was arranging a deal to sell Competitron to Wayne Enterprises. Nygma resurfaced as "The Riddler," kidnapping Mockridge and planning to kill him. The Riddler offered Batman a chance to save Mockridge, presenting a series of puzzles and riddles to solve, ending with a run through the maze at the Riddle of the Minotaur amusement park (an actual simulation of the game).

Confident in his genius, the Riddler was unprepared for an encounter with a rival intellect; Batman outwitted him, solving the final riddle. Though the Dynamic Duo survived the maze and saved Mockridge, the Riddler had escaped, leaving Gotham City altogether. In a way, Riddler still had his revenge: though Mockridge made millions from the sale of Competitron, he was paralyzed by fear of Nygma's return, seemingly for the rest of his days.

Because Batman has figured out his true identity, the Riddler undertook a campaign to eliminate all traces of his former self, breaking into banks and government buildings to destroy records bearing his name. He also sent a computer to the Gotham Police with a virtual reality simulation that ended up trapping Commisioner Gordon. Batman entered the virtual reality world to rescue Gordon, and in his concentration on defeating Batman, Riddler accidentally caused his dream world to disintegrate. Batman and Robin found Riddler at his hideout, where his brain had been temporarily suspended through an electronic backlash.

He recovered sometime later, though, briefly appearing as a member of the jury and court prosecuting Batman in Arkham Asylum. Riddler was absent, however, from the final third of the trial. This suggests he knew the inmates' freedom was to be short-lived, and fled before Batman could nab him. If so, Riddler was arrested once again.

Some time later, the Riddler was released from Arkham and appeared to have reformed. Joining with one of Gotham's well-known toymakers, Charles Baxter, the Riddler invented several puzzles that quickly became popular with children, also using his Riddler persona to boost the company's profile.

However, in secret he continued to commit daring robberies, and leaving clues through his company advertisements. Although Batman was stumped, he confronted Riddler, telling him that he knew Riddler would never be able to stop being a criminal, and that he, Batman, would catch him sooner or later. Riddler decided he was right, and lured Batman into a booby-trapped warehouse. Batman survived, however, and Riddler was returned to Arkham. He appeared to have been driven insane by his perplexity about how Batman escaped from his "perfect" trap, which Batman refused to tell him.

When The Judge was incarcerating rogues, The Riddler appeared conducting a random heist. The Judge dropped an over-sized book on him, which seemingly killed him. He survived to resurface once again though, against all odds.

Riddler, the Mad Hatter, and Bane banded together to control Gotham during Batman's mysterious absence. With Batman mysteriously gone, few could challenge them. However, Superman had arrived in Gotham and, impersonating the Dark Knight with Robin's aid, quickly foiled their scheme.

Abilities and Equipment
The Riddler had no metahuman powers, but had a genius level IQ. He had an encyclopedic knowledge of a wide variety of subjects, which he incorporated into his riddles and puzzles. He was also quite skilled with technology, and had developed several cutting edge inventions.

His question-cane incorporated several different weapons, including firearms and hacking equipment.

Batman understood that his major weakness was his inability to resist showing off how smart he was, by leaving clues that invited someone to try and catch him. To do him credit, Batman was usually the only one who could, which Riddler acknowledged, calling Batman "the only one worthy of the game."

Revamp
Like most of Batman's rogues, the Riddler underwent a revamp when he transferred from to. His outfit changed significantly, sporting a green, question mark branded jumpsuit as opposed to the question suit-coat. His appearances in the latter series were brief, and he had no episodes specifically featuring him.
