 DA Harvey Dent is hideously scarred down one side, by an acid attack. The result is 2 personalities and 2 faces. Ideal qualifications for a politician you might think, but Two-face s only policy is vengeance on Batman. He teams up with Edward Nygma, a technical wizard who invents a brain-sucking TV and adopts the alto-ego of The Riddler. MEANWHILE...in the circus, Dick Grayson witnesses his acrobat family plummet earthwards and get a taste for sawdust. Two-face is to blame but Dick trades his anger for a rubber suit and becomes Robin. Two bad guys, two good guys and 8 personas.
