Not much is known about Enigma. She briefly joined the Teen Titans after Infinite Crisis, but like most of the members during that time she left. During this period, she was known as the Riddler's Daughter and seemed to be friends with Duela Dent. She is as talented at riddling as her father, throwing in some jokes from time to time. Enigma also wields a question mark-shaped cane as a weapon. One Year Later, she is a member of Deathstroke's villainous Titans East, now known as Enigma. During a battle, she says to Dent "Wait'll dear old daddy gets a load of us!", implying that they may be sisters, or at least in Duela's mind they are. Enigma and Duela later psychologically tortured Raven inside a hall of mirrors. There, she revealed that she joined Titans East as a way of getting her father, the Riddler, to accept her. It is revealed that the Joker's daughter is actually the daughter of the Jokester of Earth-3 and was part of the Riddler Family. In Enigma's first post-Teen Titansappearance, the main DC Universe Riddler confirms Enigma to be his daughter. She later alongside Riddler while fighting Batman. At the story's conclusion in Batman #712, the Riddler asks her, "What's purple and green and bleeds profusely?" Enigma's response is cut short by her scream.
Second Enigma
In issue #1 of the Trinity miniseries, a mysterious man, whose face is half-obscured by a metal mask and who is wielding a powerful staff, joins forces with Morgaine Le Fey. His true name is unknown, but he takes the moniker "Enigma", from what Le Fey initially called him. Along with Morgaine, he plans to conquer the Keystone Universe, a.k.a. New Earth, the current mainstream DC Universe, by forcibly integrating the personality of the Trinity, the group formed by Superman, Wonder Woman and Batman, and collecting artifacts related to their personal origins. The costume and theme are suggestive of the Riddler, who often goes by the alias Edward Nigma/Edward Nygma, but Enigma's true identity is deliberately kept a secret until later in the series. Approaching to the revelation, several clues are scattered throughout the miniseries: the Riddler claims to recognize the modus operandi of Enigma as his own, therefore askingDick Grayson more time to exculpate himself. Morgaine, feeling Edward Nygma's life-force while he was at Madame Zodiac's mansion, claims that Riddler and Enigma share the same life-force, or a similar one. Enigma seems to have a personal connection to the Anti-Matter Earth, as evidenced by an emotional outburst when Despero suggests conquering it. This is confirmed when Enigma teleports himself to a base orbiting the Anti-Matter Earth. Eventually, Enigma is unmasked when he attempts to sap Superman's powers via red sunlight radiation, but reversed in wavelength, which is ineffective over a being of New Earth; this spurs Superman into scanning Enigma's body with his X-ray vision, confirming that he is the Anti-Matter Earth's Riddler. His backstory is later recounted: As the Quizmaster, Edward Nashton had formed the Justice Underground to challenge the Crime Syndicate's superiority. Eventually, Nashton's face was burned by Ultraman'sheat vision, with his wife and infant son killed and his daughter's body nearly destroyed. In retaliation, Nashton set out to change the Anti-Matter Universe, using the power of the Trinity to do so. Enigma and his allies successfully steal the Trinity's power, only for them to return as godlike beings. Enigma realizes that what they received was not the totality of the power they could have accrued and he devises a plan to complete this power, bickering with Morgaine over her usage of power. Ultimately, their second attempt fails when the godlike Trinity returns and Morgaine strikes a deal with Krona, hoping to gain his power by giving him the living soul of Earth, in return for the human soul within Enigma's robotic aide, S.P.H.E.R.E., the soul of Enigma's daughter, to replace it, with Morgaine holding her power over her. Enigma refuses and attacks Morgaine and Krona, only for S.P.H.E.R.E. to send him to the safety of the Anti-Matter Universe. Enigma returns, having gained the aid of the Crime Syndicate, to help defeat Krona. When the Earth's soul is released, it rejects Krona and restores Enigma's daughter to life, fusing her soul with that of Krona's Void Hound. When the conflict is over, the two return to the Anti-Matter Universe, hoping to give its inhabitants hope.
