Does riddler survive being shot in the stomach by Joker?
The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman.  In the eight-part story-arc "War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kill Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed.  Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo are then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave.  Riddler eventually formed his team, consisting on himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who'd convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of No Killing in order to stab Riddler. However Joker, who finally begins to laugh again, prevents Batman from doing so.  The present day Riddler shows up next in 'Deathstroke #25' as a member of The Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped. CANNOTANSWER
Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed.
The Riddler (Edward Nigma, later Edward Nygma and Edward Nashton) is a supervillain appearing in American comic books published by DC Comics. The character was created by Bill Finger and Dick Sprang, and debuted in Detective Comics #140 in October 1948. He has become one of the most enduring enemies of the superhero Batman and belongs to the collective of adversaries that make up his rogues gallery.

In his comic book appearances, the Riddler is depicted as a criminal mastermind in Gotham City. He has an obsessive compulsion to incorporate elaborate riddles, puzzles, and death traps in his schemes to prove his intellectual superiority over Batman and the police. His real name–Edward Nigma–is a pun itself; an "enigma" is a person or thing that is difficult to understand. With this self-conscious use of a gimmick, the Riddler's crimes are often theatrical and ostentatious. The character commonly wears a domino mask and either a green unitard decorated with question mark prints, or a green suit and bowler hat. A black, green or purple question mark serves as his visual motif.

The Riddler has been adapted into numerous forms of media, having been portrayed in live-action by Frank Gorshin and John Astin on the 1960s television series Batman, Jim Carrey in the 1995 film Batman Forever, Cory Michael Smith on the 2014 FOX series Gotham, and Paul Dano in the 2022 film The Batman. John Glover, Robert Englund, Wally Wingert, and others have provided the character's voice ranging from animation to video games.

Fictional character biography

Criminal career

The character's origin story recounts Edward Nigma's fascination with puzzles from a young age. After a teacher announces that a contest will be held over who can solve a puzzle the fastest, Nigma sets his sights on winning this, craving the glory and satisfaction that will come with the victory. He breaks into the school at night to practice the puzzle until he is able to solve it in under a minute. Due to this he wins the contest and is given a book of riddles as a prize. His cheating rewarded, Edward embraced the mastery of puzzles of all kinds, eventually becoming a carnival employee who excelled at cheating his customers out of their money with his bizarre puzzles and mind games. He soon finds himself longing for greater challenges and thrills and dons the disguise of the "Riddler" to challenge Batman, believing him to be a worthy adversary. In his first encounter with the Dynamic Duo, Riddler first tried to confound the crime-fighters with his infamous double-entry Riddle Clues and then tried to kill them both in a booby-trapped glass maze on a pier, sealing the door so they couldn't leave the structure before it exploded, only for Batman and Robin to escape and the Riddler "vanishing" after getting knocked into the sea by the explosion, leaving only his trademark "?" floating in the water.

In Batman: The Long Halloween, the Riddler appears as an informant. The Riddler is hired by Carmine "The Roman" Falcone to tell him the identity of the Holiday Killer. Falcone eventually loses his patience with Riddler and has his daughter throw him out on the 1st of April. Outside Falcone's he is confronted by the holiday killer who fires several shots at him without harming him due to it being April Fool's, the killer also leaves several items pertaining to their identity at the scene. This may be why Riddler was left alive, as matters are traditionally reversed on the holiday. He appeared again in the same chapter of the story in which Harvey Dent is disfigured when Batman comes to him for information about the attack. He plays a slightly larger role in the story's sequel Batman: Dark Victory, in which Batman turns to him to figure out the significance of the lost games of hangman that are left at the scenes of the Hangman killer's crimes. He later showed up as a member of Two-Face's jury during the Hangman's trial.

In Catwoman: When in Rome, he joins Selina Kyle on a trip to Italy in search of his fellow rogue's origins. It is there that he manipulates her into believing that some of Batman's most dangerous foes are after her. He has his henchmen employ several gimmicks and weapons used by the Scarecrow, Mr. Freeze and the Joker to achieve this. He hopes to extract Batman's real identity from her, but to his dismay, she actually doesn't know or care. The Riddler appears in The Question series, being convinced to become a "big-time villain" by a prostitute he meets on a bus. He hijacks the bus and begins asking riddles, killing and robbing anyone that gets them wrong. Question quickly subdues him by asking him philosophical riddles in return. He is outwitted and has a mental breakdown before being set free as a reward for getting one last riddle right. In the one-shot "Riddler: The Riddle Factory", the Riddler becomes the host of an underground game show that focuses on digging up dirt on celebrities. Many of the famous people that he humiliates end up committing suicide shortly afterward, suggesting that perhaps Riddler did more than just inspire their deaths. In the end, his actions turn out to be a front for his attempts to find the hidden treasures of "Scarface" Scarpelli, a Gotham City gangster who lived long before Batman's reign of crimefighting.

In the three-part Batman: Legends of the Dark Knight storyline "The Primal Riddle", written by Steve Englehart, the Riddler engineers one of his greatest deathtraps: Batman is thrown into a narrow pit that is slowly filling up with water. The walls are electrically wired, and a set of bumpers are the only thing that prevents the water from touching the walls and causing Batman to die by electrocution. The only options Batman appears to have are death by electrocution and death by drowning, but as always, Batman manages to tamper with the trap's design and develop a route of escape. After Harley Quinn briefly breaks free of her devotion to the Joker, she attempts to hold up a large party at Wayne Manor, only to find that the Riddler is targeting the building also. The two gangs engage in a firefight, but Harley gains the upper hand when Big Barda (who was secretly allied with her at the time) interrupts the conflict and captures the Riddler and his men. During the storyline, Riddler makes constant allusions to a "mystery" that is hidden within the mansion, and after his apprehension, damage done to the building causes the entrance to the Batcave to open. Riddler sees this, and then declares that he has "solved the riddle of Wayne Manor". During this period, he attacks Black Canary and Green Arrow in Star City, and he is easily defeated. This event helps lay the foundations for Riddler's future confrontations with Green Arrow.

During a crisis caused when Wonder Woman's Lasso of Truth was broken, resulting in the laws of truth breaking down and causing reality to be shaped by the perceptions of individuals, one of the symptoms was when Batman found himself unable to solve any of the Riddler's riddles but was nevertheless still able to defeat Riddler as Riddler himself could not solve the riddles eithermost likely reflecting the public idea of Riddler's puzzles being insolubleclaiming that he managed to "improvise" to defeat Riddler. His low reputation among heroes and villains was reflected when the Flash noted that Batman having trouble with Riddler was a clear sign that the world was ending.

Batman: Hush
In the 12-part storyline Batman: Hush, it is revealed that Riddler suffers from cancer (specifically a brain tumor), which also afflicted the mother of Dr. Thomas Elliot. Riddler uses one of Ra's al Ghul's Lazarus Pits to cure himself and offers Elliot the chance to cure his mother as well, provided he pays a large sum of money. However, Elliott is, in fact, eager for his mother to die in order to inherit her fortune. Elliott, who goes on to secretly become the masked criminal Hush, explains he wants to get revenge on his childhood friend Bruce Wayne. The two of them agree to work together and Riddler sets Killer Croc, Poison Ivy, Harley Quinn, Joker, Clayface and Scarecrow out to destroy Batman, with Ra's, Talia al Ghul, and Lady Shiva being temporarily drawn into the scheme as well.

During the psychotic break that follows exposure to the Lazarus Pit, the Riddler deduces Batman's secret identity; he then reveals his knowledge to Hush. He has Clayface shapeshift into the form of Batman's presumed deceased protégé Jason Todd in order to torment Batman, who is haunted by the former Robin's death. Batman first thinks that Riddler had stolen Todd's corpse and hid it, but it was revealed in a later storyline, Batman: Under the Hood, that Todd was alive the whole time and had personally played a role in Riddler and Hush's scheme. When the Riddler threatens to expose Batman's secret identity, the Caped Crusader mockingly labels it an empty threat, pointing out that if Riddler revealed the answer to the riddle "who is Batman?", it would become worthless, something Riddler would not be able to stand. In addition, Batman warns him that if he reveals the secret, it would give Ra's al Ghul a vital clue that he used a Lazarus Pit without his permission, and the League of Assassins would subsequently retaliate against him.

Aftermath
The fallout from the Riddler's failed scheme is played out in Batman: Gotham Knights #50-53. In the story "Pushback", Hush reappears and beats Riddler senseless across a rooftop. Seeking refuge, Riddler goes to the Joker and the Penguin. He offers to tell the Joker who had killed his pregnant wife Jeannie if the Clown Prince of Crime would protect him from Hush. Joker immediately agrees, but eventually, Hush, with the help of the impostor Prometheus, defeats him, forcing Riddler to flee for his life. In Detective Comics #797-799, the Riddler seeks shelter from Poison Ivy only to be humiliated. Riddler and Poison Ivy then face off in a physical duel, which Ivy wins easily.

As revealed in Batman: Legends of the Dark Knight #185-189, the Riddler is stripped of his deductive powers and left to rot as a member of Gotham City's vast and invisible homeless population. A chance encounter with an ex-NSA codebreaker gives him a positive environment in which to recover his mind. During that stay, he experiences an induced flashback that leads him to realize that his father had abused him many years ago. Envious of his son's academic achievements in school, and unable to understand his brilliance, his father believed he had cheated on his accomplishments, and beat him out of jealousy. Once Riddler discovers this, he also realizes that his compulsion is born out of a strong desire, to tell the truth, to prove his innocence of deception. Having made this connection, the Riddler spends some of his vast fortunes, acquired over many years of crime, to get minor plastic surgery and extensive tattooing, covering most of his torso with his trademark question insignia. He returns and kills the codebreakerwho had pieced together his identity but couldn't act on itthen promptly steals a priceless scroll out from under Batman's nose. Since then, Riddler has spent most of his time either legally amassing a huge fortune or attacking various heroes in order to prove his new-found power.

After orchestrating a brutal series of assaults on Green Arrow, as revenge against his defeat at his hands during the "No Man's Land" era, Riddler gravely injures and almost kills both Green Arrow and Arsenal. He once again escapes before the Outsiders arrive to save them. Sometime between this incident and the events of Hush, Riddler was hired to steal artifacts imbued with mystical powers from one of Star City's museums, and then distract the authorities so that the related rituals could be commenced. He sends Team Arrow on a wild goose chase around the city and then reveals that he has an atomic bomb housed in the stadium where the Star City Rockets play. However, as a side effect of the ritual performed with the artifacts, the city is plunged into complete darkness, and Green Arrow uses this to his advantage, moving in and apprehending the Riddler.

Riddler later shows up in Infinite Crisis #1, with a group of villains, which includes the Fisherman and Murmur, attacking the Gotham City Police Department. He is next seen escaping Arkham Asylum during the worldwide supervillain breakout engineered by the Secret Society of Super Villains in Villains United: Infinite Crisis Special #1, which takes place only days after the prior supernatural disaster. Riddler reappears as part of the Society's "Phase Three" attack on Metropolis. He is defeated by the Shining Knight and is struck in the head by the Knight's mace.

Riddler reformed
In Detective Comics #822, the first of a series of issues written by veteran Batman writer Paul Dini, the Riddler returns, having spent much of the previous year in a coma due to brain damage after being struck in the head by Shining Knight. When he awakes, he is cured of his insanity and of his obsession with riddles, while retaining both his genius intellect and his mammoth ego. He has seemingly reformed and becomes a private consultant who takes on the murder case of a wealthy socialite. Hired by the socialite's father, he proves that a photo of Bruce Wayne apparently implicating him in the crime depicts an impostor and briefly works with Batman to investigate the crime. He has suffered severe memory loss from the coma, and he barely remembers his own name. He does not appear to remember that Wayne and Batman are one and the same, although he does harbor some suspicions of once knowing something amazing about Wayne.

In Detective Comics #828, the Riddler is a guest along with Bruce Wayne on board a ship during a party. During the party, an old friend of Bruce's falls overboard and is mauled to death by sharks. Riddler appears to solve the case with the suicide of the apparent murderer, and quickly takes the credit. However, Batman finds evidence that suicide was a setup to divert attention away from the real killer. Bruce suspects foul play, and eventually tracks down the killer, whom Riddler is also close to catching before Nigma is bludgeoned over the head by a shark-tooth club. The killer pushes Batman out the window and is about to drop him to his death, when Nigma wraps his tie around an arrow, lights it on fire, and shoots it into the killer's back. As the assailant rolls around screaming, Nigma taunts him, refusing to douse the flames. Batman extinguishes the flame and responds to Nigma's assertion that they are now allies with hostile dismissal. In Detective Comics #837, Riddler is hired by Bruce Wayne to track down an experimental drug developed by Wayne Enterprises, currently being tested for muscle stamina and cellular regeneration, which has been stolen by the lab assistant Lisa Newman. He discovers that Newman is staying at the same Athenian Women's Help Shelter as Harley Quinn. With Harley's help, he defeats Newman and returns the drug to Wayne Enterprises, earning Batman's trust for the time being.

In Countdown #42, Riddler claims to Mary Marvel that he has gone straight and is now a detective. The two join forces to defeat Clayface, and after witnessing Mary's new malicious approach to crime-fighting, suggests that she consider finding a mentor to help her control her powers or at the very least get some anger management counseling. After a serial killer surfaces on the streets of Gotham City, the Riddler homes in on closing the case, only to find that the killer is actually one of his former victims out for revenge. The young man, whose girlfriend was caught in the crossfire of a gunfight between Nigma's gang and security guards, captures Riddler and attempts to kill him, but Batman intervenes just in time and saves his former foe's life. In the 2008 mini-series Gotham Underground, Riddler investigates the Penguin's involvement with the events of Salvation Run. He saves Dick Grayson working undercover during the Gotham Gang War between Penguin and Tobias Whale and deduces that Grayson is Nightwing.
He appears in Battle for the Cowl: The Underground, where he is hired by the Penguin to find Black Mask. To that end, he tracks down Selina Kyle, meeting up with Harley Quinn and Poison Ivy in the process.

In the Gotham City Sirens storyline, Poison Ivy is controlling the Riddler, keeping him in a nearly vegetative state so she can move into his house. When a villain named Boneblaster decides to make a name for himself by killing Catwoman, the fight ends up there. The house is severely damaged, but Riddler is freed from Ivy's control in the process. Seeing his house in shambles, he takes his question mark cane off the wall and begins to savagely beat the already downed Boneblaster. In the third issue, Riddler attempts to solve a pair of unlikely suicides, the first being the second-best female tennis player in the world, the second an ace race car driver. During his re-enactment of one of the deaths, he is visited by both Catwoman and Poison Ivy, seeking his help in locating Harley after her abduction. Due to the events of the first issue, and Harley's mental state, he quickly declines and brushes off Poison Ivy's threats.

In his efforts, he discovers that these deaths are in fact homicides orchestrated by a serial killer who leaves subtle clues to the next victim within the body and time of death of the current victim. While attempting to alert the media, he provokes Dick Grayson, who is now acting as Batman. Almost instantly, Riddler deduces that the Batman before him is a new one. Additionally, Riddler reveals that the next victim will be the sister of the second victim, a young romance writer, something that Dick needed Alfred Pennyworth and the Batcave computer to figure out. In the end, Dick goes off to confront the killer, while Riddler agrees to look after the intended victim. After a brief, but an expected misunderstanding about Riddler's intentions with the young woman, Dick phones in to announce that he has apprehended and questioned not one, but three killers about their intentions, but got no answers. Riddler almost leaves the woman to her life, when the lights go out unexpectedly. Riddler immediately concludes that Dick has not captured all of the killers, and pulls the woman out of harm's way when a bomb goes off in front of her bookstore.

While Riddler and the writer hide as the smoke clears, three costumed assailants, enter the wreckage, looking for their victim to mark with their next riddle. The two men are led by a woman going by the moniker Conundrum, and their costumes sport black and green color schemes along with disturbingly familiar question mark emblazoned on their outfits. As Riddler stealthily disposes of the two grunts with his cane, Conundrum takes the writer hostage at gunpoint. Riddler deduces that Conundrum and her men are all college students who specialize in police sciences. Due to his famous rehabilitation, Conundrum's group decided to fill the void with their debut murders. Conundrum admits that Riddler was her idol and that it would be a shame to kill him.

At this point, Riddler announces that Batman is en route to their very location, something both Conundrum and the writer have difficulty believing. Riddler claims that since his reform, he and Batman have become close and that his cane now has its own GPS that alerts Batman to his location whenever the question mark is twisted. Noting her disbelief, Riddler calmly asks Conundrum with a smirk, "Why is this man smiling?". Just as the Riddler finishes his question, Dick shows up and knocks Conundrum out. Riddler then admits that he is completely baffled that Batman is indeed there since he was only stalling for time until he thought of something, leading him to wonder if there truly is a Bat-signal in his cane (a panel during Riddler's "bluff" shows that there is indeed a Bat-signal in his cane, as a green question mark alongside a map shows up inside the Batmobile's window). After the ordeal is over, the young writer hugs Riddler, thanking him for saving her life. Afterward, she and Riddler go out to dinner at a fancy restaurant, under Dick's covert surveillance. Dick admits that Riddler is indeed on a path of recovery, but must still be watched. After washing up in the men's room, Riddler sees a gossip show on closed-circuit television, showcasing a plainclothes Harley getting into a car with Hush disguised as Bruce Wayne. He then calls Selina and tells her to turn on her television. Sometime later, Riddler arrives at his office to find his secretary bound and gagged at her desk, with Harley, Ivy, and Selina waiting in his office. The women tell him that they are being framed for the murder of a young woman whose body was dropped into their pool, and they need his help to prove that they had no part in it. After examining the woman's body, he finds that the women were telling the truth, only to be attacked by Dr. Aesop.

Return to villainy
In Tony Daniel's "Life After Death", Riddler appears early in the story at a gala party attended by Arkham, Dick Grayson, Huntress, and Oracle, hired by Penguin to find the Black Mask. As he chases Catgirl away from her robbery of the venue, the Riddler is rocked by a bomb detonation, the trauma re-awakening his psychosis. Cackling, rambling and insane, he terminates his contract with Cobblepot and disappears. In "Riddle Me This", the Riddler still "acts" as a private eye and teams with Batman to solve the murders of a mysterious sorcerer named Sebastian Rothschild (aka Sebastian Blackspell). Blackspell is apprehended, but only after Batman suspects Riddler went to great lengths to orchestrate the ordeal, including poisoning himself with a nearly lethal dose of Joker gas to skirt suspicion and act on a grudge between him and Blackspell.

Riddler's return to villainy is cemented in "Eye of the Beholder". Investigating the Sensei's attack on the Jade Society, Batman (Dick Grayson) is ambushed by Riddler and a young woman introduced as Enigma, Riddler's daughter. Riddler and Enigma escape, delivering the Jade Society member list to Gilda Dent. Riddler is paid but is more interested in another reward, which Gilda promises after one more job. This occurs in "Pieces", where Gilda reveals herself to her estranged husband Harvey, who is now the disfigured criminal Two-Face. She hires Riddler and Enigma to help Two-Face best Mario Falcone and reclaim his coin. The plan works; Riddler and Enigma defeat Batman and reunite the Dents. The Riddler is rewarded with multiple dossiers of himself. When Enigma calls him a has-been, Riddler retorts with a new riddle: "What's green and purple and bleeds profusely?". Enigma's response is cut short by her scream, implying that the Riddler has murdered his own daughter.

The New 52
In DC's 2011 relaunch of all of its monthly titles, The New 52, Riddler appears as an inmate at Arkham Asylum in Batman #1. Redesigned in the style of the new titles, he sports a green mohawk in the shape of a question mark. Riddler appears in more traditional form in the short that concludes Batman #15 "And Here's the Kicker", the third part of "Death of the Family". After it is revealed that Joker has secretly hijacked Arkham Asylum, Riddler is depicted as a current inmate, calmly biding his time and taunting guards. But when Joker appears and reveals his great respect for Riddler (as the villain whose dangerous intellect has kept Batman "sharp"), he uses Joker-gas to force Riddler to prove he could have escaped his cell anytime he wanted. To his chagrin, Riddler does and becomes quite alarmed when Joker shares a write-up of his plan to ambush Batman. Joker admits Riddler will have little part in his designs but should stick around for the "show" anyway.

The Riddler made an appearance in Batman, vol. 2, #21, the opening book of the "Zero Year" arc, where his surname is changed from Edward Nigma to Nashton or Nygma. The Riddler later appears in both the second and third chapters of the "Zero Year" storyline. In the canon, the Riddler is Batman's first masked supervillain and is not only able to best Batman twice, but also takes control of Gotham, causing it to become a flooded wasteland where only the intelligent are meant to survive. Although the Riddler continues to be steps ahead of the Dark Knight, he is eventually defeated by the combined efforts of Batman, Commissioner James Gordon and Wayne Enterprises CEO Lucius Fox. He is later moved to Arkham Asylum.

Riddler appeared one more time in New 52 in the last three issues of Flash. Holding a presumed dead Heat Wave hostage, it is revealed that the Riddler designed a range of deadly drones around Central City, drones that he had out-sourced to the CCPD. Alongside the Trickster (whose arm Edward had placed a bomb in), Riddler begins ruthlessly punching and beating the Flash (Barry Allen) before the speedster is quickly rescued by the Pied Piper. Riddler then threatens to have his drones open fire on the citizens of Central City once more. However, he is eventually defeated and imprisoned by a uniformed effort between the Flash and the Rogues.

DC Rebirth
The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman.

In the eight-part story arc "The War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kills Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed. Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo is then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However, Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave.

Riddler eventually formed his team, consisting of himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who had convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of no killing in order to stab Riddler. However, Joker, who finally begins to laugh again, prevents Batman from doing so.

The present-day Riddler shows up next as a member of the Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped. In the Watchmen sequel Doomsday Clock, Riddler hosts an underground meeting with the other villains to talk about the Superman Theory. The meeting is crashed by Comedian who shoots Riddler in the leg.

Characterization

Skills and abilities

The Riddler is a criminal genius capable of extraordinary lateral thinking in decoding and formulating puzzles of all kinds. As a private detective during the time he was reformed, he demonstrated investigative skills that rival those of the Dark Knight. However, Batman's observations note that "[Nigma] exhibits personality disorders consistent with a fanatic narcissist, egocentrism, and megalomania crossed with severe obsessive compulsion".

Like most of Batman's enemies (and Batman himself), the Riddler has no superhuman abilities but is a highly cunning criminal strategist. He is not especially talented in fisticuffs (although his endurance has grown from having to engage in it over the years), but sometimes employs weaponry that exploits his gimmick, such as exploding jigsaw pieces, question-mark-shaped pistols, and his infamous question-mark staff, known to house a wide variety of technological devices and weapons. He is shown to be skilled with engineering and technology, having confronted Batman and Robin with unique and elaborate deathtraps. He is also well known for being Batman's most intelligent adversary, and with a flexible theme to his crimes compared to similar criminals: all the Riddler requires is to be able to describe his threatened crime with a riddle or puzzle.

However, the threat that Riddler actually poses is somewhat inconsistent across his various stories. His most formidable depictions emphasize his intelligence and cunning, portraying him as one of few rogues capable of seriously taxing Batman's mental prowess, while also willing to take the precaution of obtaining firearms to deal with the superhero. Some recent depictions, however, have placed a derogatory focus on his flamboyant gimmickry, and (like most of Batman's enemies) relative lack of major victories, portraying him as petty, overconfident, relatively harmless, and held in low esteem. The latter approach has proved polarizing, with some fans finding it wasteful in light of the character's classic status and history of compelling stories, while others argue that most of his popularity has come from media other than his comic storylines and enjoy the notion of knowing that his "real" threat level is overrated. Since The New 52 reboot, Riddler has been consistently depicted as a serious threat, with notable successes.

Relationships
The Riddler has a working relationship with the Cluemaster, although he initially resents the villain for seemingly copying his modus operandi. In their first encounter, he sets his fellow rogue up with a bomb and sends Batman off chasing riddles that would lead to its defusing, as well as away from his real plan: to steal a vast amount of priceless baseball merchandise. The two team up on a few occasions afterward and work together on a big scheme shortly before Cluemaster's apparent death in the pages of The Suicide Squad.

DC Comics' 2022 Valentine's Day special, Strange Love Adventures #1, introduced the people the main continuity Riddler has had a romantic interest in, including a man named Antoine Moray and the women Miss Grantham, Jasmin Shroff, and the villain The Quiz (Miyu Tangram), confirming that canonically he is at least bisexual.

Other versions
As one of Batman's most famed and popular adversaries, a number of alternate universes in DC Comics publications allow writers to introduce variations on the Riddler that are not part of the official DC continuity, variations in which the character's origins, behavior, and morality differ from the mainstream setting.

Joker

A radically different interpretation of the Riddler is featured in Brian Azzarello and Lee Bermejo's Joker. In this version, he wears a solid green jacket with question marks on the very back of it and a circle of question mark tattoos around his abdomen. His cane serves the purpose of helping to prop him up, due to a disabled leg. In the story, he sells an unknown substance to the Joker, who identifies him as "Edward".

Thrillkiller
In the Elseworlds miniseries Thrillkiller, Nygma is a psychiatrist who counsels Barbara Gordon. Doctor Edward Nygma, author of Riddle Me This — What Do We Really Mean?, keeps Barbara dosed with increasing amounts of Valium and encourages her to mix with people that she actually loathes. Edward wears a green suit and the cushions of his couch bear the pattern of the Riddler's outfit. Alfred, Barbara's butler, takes the drugs away from her at the request of her father Commissioner Gordon, who considers Edward to be a quack.

Batman: Earth One
The Riddler appears in the graphic novel series Batman: Earth One. This version of the character is a nameless serial killer who puts people in life-threatening situations, all while questioning them in riddles, claiming that if they get it right, he will spare them; in fact, this is all a ruse, as he kills them regardless of whether they answer the riddles he proposes or not. Even though he is not obsessed with finding answers to most riddles, the Riddler does have an obsession with learning the Batman's identity, which he considers to be the "ultimate riddle".

In Volume Two, six months after the death of Mayor Oswald Cobblepot, the Riddler goes on a killing spree in Gotham City, hoping to get Batman's attention. After a bombing, Batman chases the Riddler, but falls off a roof in the process of attempting to catch him. Though Batman finds the Riddler's sewer-based hideout, he fails to stop him from bombing a rapid transit train. Using discovered clues, Batman deduces that these killings were not random; they were actually targeted, specifically that the Riddler is targeting the people who are trying to take over the remains of Cobblepot's criminal network. Bruce is later accused of being the Riddler after the real Riddler frames him in an attempt to divert James Gordon's investigation, but Jessica Dent is able to provide Bruce an alibi so he is not arrested. In the middle of a riot at the police precinct caused by the Riddler, Batman pursues the villain in a car chase and eventually subdues him with Waylon Jones' help. The Riddler is subsequently arrested by the Gotham City Police Department and brought up on 43 charges of murder.

Batman/Judge Dredd: The Ultimate Riddle
In the Batman/Judge Dredd crossover Batman/Judge Dredd: The Ultimate Riddle, the Riddler uses a reality-manipulating wand-like device he acquired during the Zero Hour crisis to pull Batman, Dredd, and six alien warriors together, intending to pit Batman against the other warriors and get him killed. However, Batman and Dredd are able to work together to overcome their opponents, culminating in Dredd shooting Riddler in the shoulder and Batman claiming the device, subsequently using it to return the survivors home.

Justice
The Riddler's appearance in Alex Ross' 12 issue series Justice suggests a new motivation, that, as a child, he had been beaten by his father whenever he told a lie, to the extent that he was now psychologically incapable of telling a lie. His riddles are his method of subverting his condition so that he is still technically telling the truth, but always in as cryptic a manner as possible.

Antimatter Universe
The Riddler has a heroic counterpart in the antimatter universe called the Quizmaster, who is a member of Lex Luthor's Justice Underground (that Earth's version of the Injustice Gang) which opposes the evil Crime Syndicate of Amerika. He first appeared in JLA Secret Files 2004 #1. He later has the right half of his face burned by Ultraman, leading him to don a half-face and temporarily take on the name "Enigma". He last appeared in the Trinity series. As the New Earth Riddler slowly became a lighter, less criminal figure, Enigma became a darker figure in this series, attempting to join forces with Despero and Morgaine le Fay to perform a ritual that will allow them to 'supplant' the Trinity of Superman, Batman and Wonder Woman and gain the power to manipulate the multiverse. In the course of the series, it is revealed that Enigma seeks this power to save his daughter after she was mortally injured, but the ritual fails when Despero is replaced by one of his henchmen in an attempted coup, creating an imbalance that destabilizes reality until Trinity's allies can regain enough of their own memories to help their loved ones come back to themselves. Similarly, on Earth-3, the Riddler's heroic counterpart (simply Riddler) is married to Three-Face (Evelyn Dent) and is the stepfather to the Jokester's daughter Duela Dent.

Emperor Joker
In the "Emperor Joker" storyline, the all-powerful Joker creates an alternate Riddler, known as "Enigma", to be a member of the Joker's League of Anarchy along with alternate versions of Poison Ivy and Bizarro. After learning of the Joker's plans to destroy the universe, he leads the League in an uprising against him. The Joker's vast and amazing powers cause the plan to fail, and the entire League is destroyed as a result.

Batman: The Dark Knight Strikes Again
The Riddler can be heard saying "ruh-riddle me this" in Batman: The Dark Knight Strikes Again.

Kingdom Come
The Riddler appears in the miniseries Kingdom Come, having been invited to a meeting of the Mankind Liberation Front by Lex Luthor. In this alternate future, the Riddler has become an old, bald man wearing glasses with question mark-shaped rims. He still indulges in his habitual riddling, asking "Who is the Riddler?" when Luthor referred to him by his real name. He appears to have been invited to the meeting only upon the insistence of Selina Kyle, as Luthor does not appear enthused by his presence.

Batman: Crimson Mist
In the third issue of the Batman vampire series Batman: Crimson Mist, the Riddler appears in a morgue where he shoots the mortician who was about to start an autopsy on a corpse where the Riddler had stored a large number of drugs. The Riddler in that appearance has a big question mark-shaped scar on his face and another one on his chest with his navel being the dot. While shooting he cites what would be his final riddle: "When Genius becomes dope plus 'E' how does she redeem herself? Answer: By turning 'Heroine' which minus the E is 'Heroin', lots of it and redeemable for lots of cash," at which vampire Batman appears and scolds the Riddler for graduating from robbery and extortion to drug trafficking and murder. In a panic, the Riddler begins to fire at Batman only to find that his bullets have no effect on him. Stunned, the Riddler asks Batman what he is, to which Batman replies: "The answer to life's every riddle: death and hungry darkness." With that, Batman proceeds to drain the Riddler of his blood.

The Batman Adventures
In The Batman Adventures #2, the Riddler makes yet another attempt to go straight. While reformed in issue #11, the Riddler struggles to avoid the temptation of crime as well as planting riddles. To remedy that, Batman recruits the Riddler to answer a great riddle: "How did the Penguin succeed in becoming mayor of Gotham City?". In the process, he is heavily injured by the Clock King, which ends up with him in a coma in issue #12. The series was canceled before the Riddler's fate could be resolved. The story planned for the Riddler would have him emerging from his coma stricken with amnesia, allowing him to solve the greatest riddle: "Who Am I?".

The character was featured in several issues of The Batman and Robin Adventures. In his first appearance, he holds an entire Christmas party hostage, convinced that Batman and Robin are among the crowd. This issue is also the debut of his two assistants, Query and Echo, in the DCAU continuity. In a later issue, he kidnaps Commissioner Gordon and threatens Gotham City with deadly nerve gas. Since Batman and Robin fail to show up, Batgirl is forced to take on the Riddler alone and save her father.

The Riddler is featured prominently in Batman: Gotham Adventures, a spin-off of Batman: The Animated Series.

Injustice: Gods Among Us
In Injustice: Gods Among Us'''s prequel comic, when the Justice League come to remove the patients of Arkham, only to be resisted by Batman and Nightwing, the Riddler watches the argument between the heroes in silence. He was about to make a riddle but Cyborg orders him to be silent. Cyborg next plans to remove him but is stopped by Batman when he activates a virus he had uploaded into Cyborg years ago. Riddler is freed by Harley Quinn alongside all the other inmates to attack the heroes. The Riddler is seen about to crush Batman's head with a large rock but hesitates as he tries to think of a riddle to say before committing the act, allowing the Green Arrow to knock him out with a boxing glove arrow, before being beaten down by Robin.

Teen Titans Go!
In the tie-in comic to the Teen Titans animated series Teen Titans Go!, one issue focused on a villain named "Kwiz Kid", whose plan was to stump Robin with riddles in an attempt to get a date with Killer Moth's daughter, Kitten. Kwiz Kid is possibly a younger version of the Riddler as he bears a number of similarities to the Riddler in both style and physicality, even down to wearing a green suit with a question mark as his symbol.

Batman: White Knight
The Riddler made a minor appearance in the 2017 series Batman: White Knight. Riddler, along with several other Batman villains, is tricked by Jack Napier (who in this reality was a Joker who had been force-fed an overdose of pills by Batman, which temporarily cured him of his insanity) into drinking liquids that had been laced with particles from Clayface's body. This was done so that Napier, who was using Mad Hatter’s technology to control Clayface, could control them by way of Clayface's ability to control parts of his body that had been separated from him. Riddler and the other villains are then used to attack a library that Napier himself was instrumental in building in one of Gotham City’s poorer districts. Later on in the story, the control hat is stolen by the Neo-Joker (the second Harley Quinn, who felt that Jack Napier was a pathetic abnormality, while the Joker was the true, beautiful personality), in an effort to get Napier into releasing the Joker persona. Riddler also appears in the sequel storyline Batman: Curse of the White Knight'', being among the villains murdered by Azrael.

Television

Live action

The Riddler appears in the 1960s Batman television series and as one of the villains in the theatrical film spin-off. Frank Gorshin portrayed Riddler in the first and third season of the series and the film and John Astin portrayed Riddler in the second season. He made four appearances in season 1 (more than any other villain) but was reduced to only one appearance per season afterwards. The inclusion of the Riddler in the popular television series was inspired by the first Silver Age appearance of the Riddler, with the premiere episode being an adaptation of Batman #171. Frank Gorshin would be nominated for an Emmy Award for his performance, which elevated the character's popularity into becoming a major member of Batman's rogues gallery of enemies.
Frank Gorshin also portrayed the Riddler in Legends of the Superheroes in 1979.
Edward Nygma is featured in the TV series Gotham, where he is portrayed by Cory Michael Smith. This version is a forensic scientist working for the Gotham City Police Department who has a fondness for expressing findings in the form of riddles. He eventually turns to crime, however, and terrorizes 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.
In the fourth episode of the first season of the NBC series Powerless, the Riddler sends his henchmen to Charm City to steal a weapon from Wayne Security that would allow him to attack Arkham Asylum. One of the Riddler's henchmen (Robert Buckley) dates Emily Locke, who worked for the firm, in an attempt to get close to the weapon. Their plot is foiled when Van Wayne enters the office in a Robin costume and the Riddler's henchmen all scatter, thinking that Batman must be nearby.
In the first-season finale of Titans, the Riddler is mentioned as being the one who paralysed Jason Todd. Todd claims the Riddler had not used a gun before. In the episode "Prodigal", his crane is shown. In the season 3 finale episode "Purple Rain", Beast Boy put in Riddler's name in the security question which he got wrong.
Riddler is name-dropped multiple times in the CW's Batwoman series, and his cell can be seen in Arkham Asylum during the "Elseworlds" crossover event.
Riddler is referenced in the fourth episode of the Peacemaker TV series as being a part of a coterie of supervillains affiliated with Batman.

Animation

DC animated universe

The Riddler appears in the DC animated universe, voiced by John Glover. For this version, the producers decided to play against the popular Frank Gorshin image of a cackling trickster to avoid confusion with the Joker, instead portraying the character as a smooth intellectual who presents genuinely challenging puzzles and dressed in a more sedate version of Frank Gorshin's preferred costume for the character from the 1960s live-action series. The series's creators admit they did not use him often because his character often made story plots too long, too complex or too bizarre, and the creators also found it very hard to devise the villain's riddles.
Riddler appears in Batman: The Animated Series. The character's design consists of a green suit and a purple mask, along with his staff that lacks the usual question mark-shaped design. In his debut episode "If You're So Smart, Why Aren't You Rich?", Edward Nygma becomes the Riddler after being unjustly fired by his greedy employer, Dan Mockridge, whom he tries to kill. Despite Batman solving his riddles, he evades capture and has the satisfaction of leaving Mockridge plagued with a terrifying paranoia of the Riddler striking again. The Riddler later appears in "What Is Reality?", where he returns to delete his identity and locks Commissioner Gordon into a virtual reality world. Batman outsmarts him, however, and finally apprehends the villain by solving his riddle. Unlike the other villains that escaped Arkham Asylum, Riddler is actually released due to good behavior. He returns in the episode "Riddler's Reform", where he works at a toy company and uses his Riddler persona to advertise them and make millions. However, Riddler finds that he cannot control his need to commit riddle-based crimes, and eventually makes a seemingly inescapable deathtrap for Batman. The Dark Knight manages to survive, however and apprehends him. When Batman refuses to tell him how he escaped, Riddler is returned to Arkham, plagued continuously by Batman's survival.
Riddler makes cameo appearances in The New Batman Adventures. The character's design is completely different: lacking the hair and mask and dressed in a unitard with a large question mark. In the episode "Over the Edge", Riddler was seen on a talk show with the other Batman villains in Batgirl's nightmare induced by Scarecrow's fear gas. In the episode "Judgement Day", Riddler was among the victims of the vigilante known as The Judge at the time he was crashing a banquet, being crushed by The Judge.
Riddler appears in Superman: The Animated Series. In the episode "Knight Time", he is in league with Bane and the Mad Hatter to take advantage of Batman's recent disappearance. However, Riddler is quickly captured by Superman (dressed as Batman) and Robin, being the latter the one who handcuffs him to the cage where he had locked him.
 Riddler makes a silent cameo appearance on Batman Beyond. In the episode "Black Out", one of Riddler's costumes is seen on display at the Batcave. Mannequins of the Riddler were also seen on display at the Batcave in the episodes "Disappearing Inque", "Splicers" and "Sneak Peek". In the episode, Terry's Friend Dates a Robot", an android drone in the guise of the Riddler fights the new Batman (Terry McGinnis). When asked about Riddler's fate, show's creator Paul Dini jokingly stated that the Riddler retired and started running a men's clothing store with the Mad Hatter as his partner.
Riddler was originally planned to appear in the third season of Justice League Unlimited, as a member of the Legion of Doom. Due to the Bat-embargo, this was not possible. This would have been a tribute to his appearance in Challenge of the Super Friends as one of the original 13 members of the Legion of Doom.
In Batman Beyond: Return of the Joker a mannequin of the Riddler is seen in the Batcave.

Other shows
The Riddler made his first appearance in animated form in the Filmation Batman installments have first seen on CBS Saturday Morning in 1968 as part of The Batman/Superman Hour, with Ted Knight providing his voice.
The Riddler did not appear in the 1977 The New Adventures of Batman episodes. However, he did appear in the show's opening wearing a red version of his outfit. He was also mentioned in the news as being arrested for a crime.

The Riddler appeared in Hanna-Barbera's Challenge of the Super Friends, voiced by Michael Bell. He appears as a member of the Legion of Doom and usually gives riddles to the Super Friends to delay them from meddling with the Legion's plans. In "Monolith of Evil", he uses a riddle to trick the Super Friends into getting a Monolith of enormous power guarded by a Lava Monster for the Legion after they fooled the Super Friends into abducting the United Nations and disguising the Monolith as the United Nations.
Riddler made his only solo appearance in the 1980s series Super Friends, again voiced by Michael Bell. In the short episode "Around the World in 80 Riddles", he uses his new Stupid Spray (which slowly causes the intelligence of those sprayed upon to be reduced to the intelligence of 2 year-olds) on Superman, Wonder Woman, Batman and Robin, where different riddles will provide clues where the antidote can be found. The first one quotes "As your I.Q. drops to below 22, you'll need mya help to tya your shoes". The answer to the riddle led Super Friends to the Mayan ruins, where they ended up in one of Riddler's deathtraps. After barely escaping the deathtrap, Superman, Wonder Woman, Batman and Robin find what appeared to be the antidote only to be a container for another riddle. The riddle reads "You're probably so dumb now, you need a simple clue. So find the tallest mountain and climb until you're blue". Due to the group's dwindling intelligence, Batman had to use the Batcomputer on his Batplane to decipher the riddle, with the answer being Mount Everest. Upon arriving at Mount Everest, Superman, Wonder Woman, Batman, and Robin encounter Riddler's blimp, where the Stupid Spray is at its final part on them. The Super Friends managed to claim the Stupid Spray Antidote and defeat Riddler. In "Revenge of Doom", Riddler was with the Legion of Doom when they got back together.

In 2005, an interpretation of the Riddler debuted in The Batman episode "Riddled", voiced by Robert Englund. This version exhibits a Gothic appearance and is served by henchmen called Riddlemen. The episode "Riddler's Revenge" reveals that Nygma and his partner Julie (voiced by Brooke Shields) worked at a university on a device to enhance the human brain. Nygma was approached by a man named Gorman (voiced by Bob Gunton) who offered to buy the rights to the invention, but Nygma refused. After the device malfunctioned at a demonstration, Nygma accused Gorman of sabotage. After an attempt to kill Gorman, Nygma fled when Batman rescued him. By the episode "Riddled", Nygma has adopted his Riddler persona. Years later in "Riddler's Revenge", Nygma tried to kill Gorman again, but Batman stopped him and Nygma realized it was not Gorman who sabotaged him, but his own partner, Julie; who betrayed Nygma out of greed, which broke Nygma's heart.
The Riddler is featured in Batman: The Brave and the Bold, voiced by John Michael Higgins. He is mentioned but not seen during Batman's call to Commissioner Gordon in "Deep Cover For Batman!". In the teaser for "A Bat Divided!", Riddler has a game show 'Riddle Me This' where Booster Gold fails to solve the riddles, harming Batman. Batman eventually frees himself and the two fight Riddler and his henchmen. Batman's riddle to Riddler is "Why are you like a clock in cement" with the answer being "Because you're both doing hard time." In the main story of "The Criss Cross Conspiracy!", he was the target of revenge by Batwoman, whom he had humiliated ten years earlier by unmasking her in public.
The Riddler appears in the Young Justice cartoon series, voiced by Dave Franco. In "Terrors", he is an inmate of Belle Reve who escapes. In "Misplaced", a spell cast by Klarion the Witch Boy, Wotan, Blackbriar Thorn, Felix Faust and Wizard splits the Earth into two dimensions as a diversion to enable Riddler and Sportsmaster to steal an organism from S.T.A.R. Labs. In "Usual Suspect", Riddler joins Cheshire, Mammoth and Shimmer in ambushing the Young Justice Team at a crashed airplane. He did a riddle upon the attack about a type of plant to which Robin answered "Ambush." Riddler is incapacitated by Zatanna and reveals Hugo Strange as a member of the Light.
The Riddler appears in the DC Nation Shorts, voiced by "Weird Al" Yankovic in the "Riddle Me This!" short. Here he asks the viewers different questions while Batman gets out of the traps answering the questions.
The Riddler makes a cameo appearance in Teen Titans Go! episode "The Titans Show", where the Control Freak brings him, along with various other supervillains, to take on the Titans.
The Riddler appears in Justice League Action, voiced by Brent Spiner. This version does not wear a mask and has a shaved head. In the episode "E. Nygma, Consulting Detective" after being released from Arkham Asylum, Riddler helps Wonder Woman and Green Arrow find Batman after he was captured by Joker and due to the fact that Joker is stealing his riddle motif. The riddles that Riddler deciphers takes them to Solomon Grundy's cell where Riddler distracts him with a finger trap puzzle, the Iceberg Lounge where the riddle was under Penguin's trick umbrella, and the Gotham Art Museum where Joker gets Wonder Woman trapped. Upon Green Arrow freeing himself from the ribbon trap, he and Wonder Woman save Batman from being cut by the Lady of Justice statue when Joker tempts Riddler to use the voice-activated trap upon solving the Mississippi riddle. Upon Joker being apprehended, it was revealed that Joker did this because Riddler ate his doughnut. As Riddler walked off, he quotes "Riddle me this, Gotham. Who's getting better and better every day in every way? Me."
The Riddler appears in the web series DC Super Hero Girls, voiced by Yuri Lowenthal. He appears as a student at Super Hero High.
The Riddler appears in the Harley Quinn animated series, voiced by Jim Rash. In "Til Death Do Us Part", he is incarcerated in Arkham Asylum, but triggers a mass breakout after smuggling in an orange seed for Poison Ivy. He later starts a crime wave before capturing both Batman and Harley Quinn in a death trap to force Joker to save one of them. After the latter chooses Batman, Riddler reveals the trap was fake and that he teamed up with Ivy to convince Harley that Joker does not love her. Following this, he makes minor sporadic appearances throughout the rest of season one, some of which established him as a member of the Legion of Doom. In the season two premiere, "New Gotham", Riddler formed the Injustice League alongside fellow villains and former Legion members the Penguin, Mr. Freeze, Two-Face and Bane to take advantage of the chaos the Joker caused when he destroyed Gotham City. The villains have divided the city's ruins between them, but refuse to give Harley Quinn an equal share, leading her to attempt to dismantle the League. In the following episode, "Riddle U", after having dealt with Penguin, Harley and her crew go after Riddler next, who's set up shop in Gotham University, upon learning his territory has power and clean water. Along the way, they discover he used kidnapped co-eds as human batteries and receive assistance from Barbara Gordon to take him down before using him to power their mall lair. He eventually manages to escape, but chooses to return for the time being as the mall offers several benefits that Gotham's wasteland does not. In the episode "Dye Hard", having apparently become muscular after running on the wheel for an extended time, Riddler is released by Doctor Psycho, who left Harley's crew to seek revenge against them, and steals a mind control helmet which Psycho uses to strengthen his psionic powers and enslave an army of Parademons in their attempt to take over Gotham and, eventually, the world. Despite their best efforts, they are ultimately defeated in the episode "Lovers' Quarrel", and subsequently imprisoned at Arkham in "The Runaway Bridesmaid".

Riddler allies with Two-Face and goes on a crime spree to found his own company, NygmaTech, to mass produce his technology, allowing him to absorb the intelligence of all of Gotham City and deduce that Bruce Wayne is Batman. Batman overloads the information flowing into Riddler's brain, causing him to be driven insane and locked up in Arkham Asylum. His costume is briefly seen at Arkham in the film's sequel Batman & Robin.

Waller forms the Suicide Squad to infiltrate Arkham Asylum in order to retrieve a memory stick containing information of all Suicide Squad members in Riddler's cane, though her real motive is to kill the Riddler, as he is the only person who knows how to deactivate the bombs that are surgically attached to the spines of the Suicide Squad members. He reveals this knowledge to Killer Frost when she is sent to kill him on Waller's instruction. The Suicide Squad then agree to spare the Riddler in exchange for his help, and most are able to deactivate their bombs with the use of a device intended for electroshock therapy. Only Black Spider (who had been separated from the group) and King Shark (whose skin is too thick) are killed by Waller when she realizes what has happened.

He then manipulated numerous villains in a series of schemes to destroy Batman on multiple fronts while having Clayface assume his identity to make it appear he has been incarcerated in Arkham. But when the plan fails, Riddler kidnaps Catwoman to lure Batman to an abandoned factory and overpower him with his newly enhanced strength. But a freed Catwoman helps Batman push Riddler over a vat of molten metal, with the Riddler killed by Catwoman cutting the rope to prevent Batman from endangering himself when he attempts to rescue the villain.

Video games

Batman: Arkham

The Riddler is prominently featured in all four primary installments of the Batman: Arkham video game series, where he is voiced by Wally Wingert. In addition to serving as one of the many supervillains that Batman has to apprehend, his presence provides much of the puzzle solving and collectible content found in each game.

 While the Riddler does not make a physical appearance in the series' first entry, Batman: Arkham Asylum (2009), he hacks into Batman's communication system early on in the story and persistently challenges the Dark Knight to solve various riddles located throughout Arkham Island and its various facilities. When Batman deciphers all of the Riddler's challenges, he is able to triangulate the Riddler's location in Gotham City and the villain is subsequently arrested by the police. Audiotapes of Arkham psychiatrists' interview sessions with the Riddler can also be found in the game, which reveals that when Edward Nashton won a riddle-solving contest at school, his abusive father accused him of cheating and proceeded to beat him, resulting in his obsession with riddles as a way to prove his intellectual superiority.
 The Riddler makes his first physical appearance in the sequel, Batman: Arkham City (2011). He, along with many of the other villains in Gotham, is captured and sent to Professor Hugo Strange's Arkham City, a lawless and walled city whose inmate inhabitants are free to wreak havoc. The Riddler kidnaps former Arkham guard Aaron Cash's medical protection team from the church, places them in deathtraps and threatens to murder them in order to force Batman to solve his riddles scattered throughout Arkham City. To discover the locations of Riddler's various trophies, challenges, and riddles, Batman interrogates his henchmen, who are embedded with gangs working for the Joker, the Penguin and Two-Face. At certain intervals, when Batman deciphers enough "challenges", the location of a room containing one of the Riddler's hostages is revealed, after which the Dark Knight must outwit the deadly traps within the chamber. The freed hostage then gives Batman a sequence of numbers from the Riddler, which correlates to a radio frequency that, once tuned in, will either give Batman a new location or tell him to find more trophies. After saving five hostages and completing 400 challenges, Oracle manages to discern the location of the Riddler's hideout. Once inside the Riddler's base of operations, Batman observes that the remaining hostages are trapped in a prolonged cycle of torture: they must continuously walk along a path or the explosives strapped to their heads will detonate. Batman must then avoid walking in front of each hostage until he reaches and manages to incapacitate the Riddler. The Riddler also plays a major role in the game's challenge mode, which is called "Riddler's Revenge". Various challenge maps show him having numerous henchmen working for him, including TYGER Guards, Ra's al Ghul's ninja assassins, Mr. Hammer and his twin Sickle, a Titan-empowered henchman, and even Black Mask.
 The Riddler's Enigma identity is featured in the prequel game Batman: Arkham Origins (2013). Edward Nashton is described as a police consultant and apparent head of the GCPD's Cybercrime unit. Here, he has yet to take up the mantle of the Riddler and is known only as "Enigma". In the game, he has set up a series of signal jammers throughout Gotham City to disrupt the Batplane as well as Batman's own hacking transmitter. He plots to blackmail several of Gotham's most prominent citizens, in the hopes of making Gotham a better place by getting rid of those who are corrupt, although in the process risking the lives of several innocent people. Enigma also has several informants and pieces of extortion recordings scattered throughout Gotham, which Batman must uncover and decode in place of the Riddler trophies of previous games. His encounter with Batman prompts Edward to go into hiding and develop his identity as the Riddler; he hints to this as he calls Batman "quite the riddle".
 In Batman: Arkham Knight (2015), during the chaos caused by the Scarecrow, the Riddler has set up several new challenges for his Riddler Trophies, some of which call on Batman to perform in the Batmobile. He captures Catwoman at one point to use as a hostage to make Batman play his game-Catwoman trapped in an old orphanage wearing an explosive collar that can only be deactivated by a series of keys that will be provided when certain riddles and challenges are solved-but Batman frees her. After solving all the riddles, the Riddler has a final showdown with Batman and Catwoman in his Riddler Mech and using his army of robots, the Riddler claiming in the aftermath that Catwoman's aid was cheating and Batman 'should' have been able to hack the robots' complex operating systems rather than just beat them up. In the prison following Scarecrow exposing Batman's true identity, the Riddler is the only one that refuses to accept that Bruce Wayne is Batman, incapable of accepting that his past theories were wrong. In the "Catwoman's Revenge" DLC, Catwoman infiltrates the Riddler's headquarters for payback after he kidnapped her, just as he is using his phone call from prison to remotely activate his army of robots. Catwoman defeats the Riddler's armed thugs and robots and transfers all his money to her bank account before leaving his factory to self-destruct.

He can also bring in two of his robotic minions for assistance.

Lego Batman

 The Riddler is a character in Lego Batman: The Videogame with his vocal effects provided by Tom Kenny. He is one of the three masterminds of the Arkham breakout, along with the Joker and The Penguin. He leads Two-Face, Mr. Freeze, Poison Ivy and Clayface, with the goal of stealing the contents of the Gotham Gold Reserve. Each member manages to steal a specific item--Clayface gets a key, Mr. Freeze gets a freeze cannon, Poison Ivy gets some mutated vine seeds and Two-Face gets a super laser—before being defeated by Batman and Robin, until only he and Two-Face remain. He breaks into the gold reserve easily and then controls a bolt-blasting machine to stop Batman and Robin, but they defeat him by destroying the gold in the boxes and building boards out of them to reflect his bolts back at him and arrest him. In this game, his trademarked question-mark cane grants him the ability to exert mind control over marked targets, or to confuse other characters if they are close enough.
 The Riddler appears in Lego Batman 2: DC Super Heroes voiced by Rob Paulsen impersonating Jim Carrey's interpretation of the character. He is one of the five villains to raid Bruce Wayne's Man of the Year award ceremony. He flees with Two-Face, the Joker and the Penguin when Batman arrives, leaving Harley Quinn to cover their flight. He appears as a boss in the level "Theatrical Pursuits" and is arrested, but he breaks out of prison with multiple other villains after Lex Luthor frees them all. He is later an optional boss fight and unlockable character found on top of Wayne Tower. His catchphrase is "Riddle me this, Batman. Why won't you leave me ALONE?" making him the only map boss that mentions Batman by name.
 The Riddler appears as a playable character in Lego Batman 3: Beyond Gotham, voiced by Roger Craig Smith.

When Deathstroke is defeated, Riddler mentions that Joker never made the payment transfer. Before departing to another location, Riddler has the players tell Batman that Joker is working with T. O. Morrow on a new Joker venom.
 The Riddler is referenced in the game Gotham City Impostors. Players are able to unlock a Riddler-inspired pattern for their weapons, depicting the iconic green background with purple questions dotted around it.

 The Riddler appears as a boss in the video game Young Justice: Legacy, voiced by Jason Spisak. During the Team's mission in Gotham City, led by Nightwing, they investigate the disappearance of Helena Sandsmark and the Riddler's securing of a piece of an ancient statue. They track down Sandsmark in Haley's Circus, but the Riddler uses a device to use Psimon's psychic powers on the team. When his scheme fails, he traps the heroes in his lair in the sewers, forcing them to participate in a deadly game show full of traps and obstacles. The Riddler eventually fights off the heroes and is defeated. It is later revealed that Riddler's pieces were a fake and he willingly served as a distraction to allow Klarion the Witch Boy to steal the real pieces.

 The Riddler appears in Telltale Games' Batman: The Enemy Within (the sequel to Batman: The Telltale Series), voiced by Robin Atkin Downes. This version of the character is never explicitly identified as "Edward Nygma", though Catwoman does refer to him as "Eddie." He is also significantly older than Batman and is known as "Gotham's original costumed criminal", who operated whilst the city was controlled by Thomas Wayne and Carmine Falcone. Despite being 60 years old, he is a skilled hand-to-hand combatant and mainly uses bartitsu with his cane. A former employee of the Agency's scientific division SANCTUS, he was the only surviving human test subject during experimentation with the "LOTUS virus"; the bioweapon maintained Riddler's youth but also drove him insane. Riddler makes his debut in the first episode of the series, titled "The Enigma". After disappearing for many years, Riddler returns to Gotham as the leader of the Pact (alongside "John Doe", Bane, Mr. Freeze, and Harley Quinn), a criminal group that plots an attack on SANCTUS's labs to steal the LOTUS virus. In his own revenge scheme, Riddler also plans to murder members of the Agency via homing missiles guided by a distinct radio signal. He also begins targeting the vigilante Batman, which inadvertently results in Lucius Fox’s death when a decoded puzzle box triggers a missile strike on Wayne Enterprises. After Batman defeats Riddler, the latter is assassinated by Fox's daughter, Tiffany, using a poison-shooting drone. Riddler's dying words are "They broke the pact," leading Batman (and others) to initially believe his partners had betrayed him. His corpse is later recovered by the Pact to create biometric keys to bypass SANCTUS security and create a usable version of the LOTUS virus. Riddler's body is later destroyed by Amanda Waller and his blood is taken by the Agency to create their own version of the virus, though the samples are ultimately destroyed by Agent Iman Avesta, much to the dismay of both Waller and Harley Quinn.
