Television
Live-action
- The Riddler appears in Batman (1966), portrayed by Frank Gorshin in the first and third seasons and John Astin in the second season. This version was inspired by the Riddler's first Silver Age appearance, with the premiere episode being an adaptation of Batman #171. Gorshin would be nominated for an Emmy Award for his performance, which elevated the character's popularity and turned him into a major member of Batman's rogues gallery.
- The Riddler appears in Legends of the Superheroes, portrayed again by Frank Gorshin. This version is a member of the Legion of Doom.
- A young Edward Nygma appears in Gotham, portrayed by Cory Michael Smith.[1][2][3] This version is a forensic scientist working for the Gotham City Police Department who has a fondness for expressing his findings in the form of riddles before eventually turning to crime and terrorizing Gotham as the Riddler. The series traces his evolution into a master criminal as well as his complicated, love–hate relationship with fellow criminal Oswald Cobblepot.
DC Animated Universe
Edward Nygma / The Riddler appears in series set in the DC Animated Universe (DCAU), voiced by John Glover. To avoid confusion with the Joker, the producers of Batman: The Animated Series chose not to portray this version as Frank Gorshin's cackling trickster from Batman (1966); instead portraying Riddler as a smooth intellectual who presents genuinely challenging puzzles and dresses in a sedated version of Gorshin's preferred costume for the character. The series creators also admit they did not use him often because his character often made story plots too long, complex, or bizarre and they found it difficult to devise the villain's riddles.[4]
- The Riddler first appears in Batman: The Animated Series (1992), with his design consisting of a green suit, purple mask, and a staff that lacks the usual question mark-shaped design. Introduced in the episode "If You're So Smart, Why Aren't You Rich?", Nygma was once a video game developer before he was unjustly fired by his greedy boss, Daniel Mockridge. Following a failed attempt on his life, the Riddler faces Batman on several occasions.
- The Riddler makes cameo appearances in The New Batman Adventures, now sporting a unitard with a large question mark and no hair and mask.
- The Riddler makes a minor appearance in the Superman: The Animated Series episode "Knight Time".
- An android drone of the Riddler makes a non-speaking cameo appearance in the Batman Beyond episode "Terry's Friend Dates a Robot". When asked about the Riddler's fate, series creator Paul Dini jokingly stated that he retired and started running a men's clothing store with the Mad Hatter.[5]
- The Riddler was originally planned to appear in the third season of Justice League Unlimited as a member of Gorilla Grodd's Secret Society as a tribute to his appearance in Challenge of the Superfriends (see below). However, due to rights issues caused by the "Bat-embargo", this was not possible.

When the device malfunctioned at a demonstration, Nygma accused Gorman of sabotaging it and attempted to kill him, only to be foiled by Batman. In the present, Nygma becomes the Riddler to make another attempt on Gorman's life, only to learn Julie was the one who sabotaged their device out of greed, breaking Nygma's heart.

Film
Live-action
- The Batman (1966) incarnation of the Riddler appears in the film of the same name, portrayed again by Frank Gorshin.
- Edward Nygma / The Riddler appears in Batman Forever, portrayed by Jim Carrey. This version is an eccentric, amoral inventor at Wayne Enterprises who designs "The Box", initially a device capable of projecting images into a person's mind but later revealed to be capable of transferring neural energy into others to enhance their intellects. After Bruce Wayne rejects his invention as the mind projection angle seems too ethically questionable, Nygma becomes the Riddler to prove his superiority to him by obsessively sending him puzzles to solve. Riddler later allies with Two-Face and goes on a crime spree to fund his own company, NygmaTech, mass-produce the Box's technology, and market it as a means of enhancing how viewers watch television; allowing him to absorb all of Gotham City's citizens' intelligence and deduce that Bruce Wayne is Batman. Ultimately, Batman shatters the master box, which reverses the information flow into Riddler's brain, driving the latter insane before he is incarcerated at Arkham Asylum.
- Edward Nashton / The Riddler appears in The Batman (2022), portrayed by Paul Dano.[10][11][12] This version is a masked serial killer, partly inspired by the real-life Zodiac Killer, who seeks to "unmask the truth" about Gotham City by targeting its upper class while taunting Batman and law enforcement with ciphers and riddles.[13][14][15][16] Additionally, Nashton is an orphan with a grudge against Thomas Wayne for not keeping his promise to fund the former's orphanage before his murder, is envious of Bruce Wayne for being an orphan who grew up rich, and ironically idolizes Batman, who served as inspiration for Nashton becoming the Riddler. After throwing Gotham City into disarray by leaking its leadership's corruption and killing the mayor, the police commissioner, the district attorney, and crime boss Carmine Falcone, Nashton allows himself to be captured and imprisoned at Arkham Asylum. Batman then discovers Nashton's true plan is to use explosives around Gotham's breakwaters to flood the city and have his followers assassinate newly elected mayor Bella Reál. After Batman saves Reál, Nashton laments his failure, but befriends the Joker.

Edward Nashton / Enigma / The Riddler appears in the Batman: Arkham video game series, voiced by Wally Wingert. This version had an abusive father who accused him of cheating in a riddle solving contest before beating him. This resulted in Nashton becoming obsessed with riddles and proving his intellectual superiority. He would later go on to become a police consultant and the apparent head of the Gotham City Police Department (GCPD)'s Cybercrime unit, during which he operated as Enigma before eventually becoming the Riddler.
- While the Riddler does not physically appear in Batman: Arkham Asylum (2009), he hacks into Batman's communication system and persistently challenges him to solve various riddles located throughout Arkham Island and its various facilities.

He, along with many of Gotham City's criminals and supervillains, was captured and sent to Professor Hugo Strange's Arkham City, a lawless, walled city whose inhabitants are free to wreak havoc. The Riddler kidnaps former Arkham guard Aaron Cash's medical protection team, places them in death traps, and threatens to murder them to force Batman to solve his riddles and challenges, which he has scattered throughout Arkham City. Additionally, the Riddler employs moles embedded in the Joker, Penguin, and Two-Face's gangs.

- A young Nashton, as Enigma, appears in the prequel Batman: Arkham Origins (2013).

To further his plot, Nashton also has informants and pieces of extortion recordings scattered throughout Gotham. After uncovering and decoding the recordings and destroying the jammers, Batman finds Enigma's hideout, but the latter has gone into hiding by then.
- In Batman: Arkham Knight (2015), the Riddler joined forces with the Scarecrow and Arkham Knight to kill Batman, built robots to assist him, established more challenges for Batman throughout all of Gotham, and coerces him into completing them by taking Catwoman hostage via an explosive collar. As he completes the challenges, Batman locates the keys needed to remove her collar before the pair confront the Riddler in a "Riddler Mech" and his army of robots. After defeating him, Batman takes the Riddler to GCPD headquarters. In the "Catwoman's Revenge" DLC, set after the events of the main game, Catwoman infiltrates the Riddler's lair while he is incarcerated and transfers his money from his account to hers before leaving his robot factory to self-destruct.

Additionally, he was the only surviving human test subject of the Agency's experiments with the "LOTUS virus", a bioweapon that allowed him to maintain his youth, but drove him insane.
