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 of America's superiority. Eventually, Nashton's face was burned by Ultraman's heat 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 (she had thoughtlessly destroyed most of Europe in her lashing out against the world). 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.
