Edward Nygma (Earth-883745)

""Are you ready for some more? Explore! Find my challenges. And when you fail to solve them and lie blubbering like an ignorant child on the floor, you will know that The Riddler is better than you""

- The Riddler

With an obsessive need for attention and genius-level intellect, Edward Nygma (formerly Edward Nashton) is determined to be the most outlandish of Gotham City's criminals, concocting elaborate series of clues and riddles around his crimes. Batman has proven a worthy opponent, capable of deducing the Riddler's plans, but Nygma is dedicated to creating a mystery the Dark Knight will not be able to solve in time to save the hostages.

Biography
Before the Enigma Show Before the events on Christmas Eve, Edward Nashton was collecting extortion data files to uncover the corruption of Gotham's officials, while also searching for the real identity of the Batman, believing he was either Harvey Dent or Bruce Wayne. At the time, he was working undercover in the G.C.P.D.'s Cyber Crime unit at this time.

The Christmas Eve Incident
""If it isn't the Bat?""

- Enigma

Nashton, given the alias of Enigma by himself, has used an army of informants to collect a cornucopia of blackmail information about the city's most corrupt individuals. Planning to release this information to the public on Christmas day he intends to trigger a chain reaction that will end in Gotham City's collapse.

Recognizing Batman as his greatest obstacle he sets up multiple layers of fail safes: including hiding his servers behind a billboard, planting signal jammers inside the Gotham City Radio towers that Batman uses to pilot his Batwing, setting up dozens of relays across the city, and employing a army of thugs to hamper him at every turn. He also used his informants to hide the extortion data he collected all through Gotham.

Enigma continued to taunt Batman as he attempted to disrupt all the radio towers, but eventually Batman succeeded. Finally, after destroying all relays, interrogating all informants and collecting all the data packs, Batman came back to Enigma's HQ and destroyed his server. Enigma accepted temporary defeat, while claiming that he now holds onto the biggest, dirtiest secret that puts his collection of data to shame. Batman later unlocked Enigma's secret room, which revealed several items of interest: newspaper clips indicating Enigma's research on the Batman's identity (with the two main suspects being Bruce Wayne and Harvey Dent), pressure pads, cages, and one green glowing question mark that would later be referred to as the Riddler Trophy. Later, Enigma was deduced to being Edward Nashton, head of The GCPD's Cyber Crime Unit, by Alfred.
