Twin teams of criminals strike in the “twin” cities of New York and Gotham: on the first team, Flamesplasher has fire powers, Darklight can create darkness, and Sizematic grows to giant size, while their counterparts have water, light, and shrinking powers, respectively. The Joker’s Daughter is suspected of duplicity when she receives telepathic “hunches” leading the Teen Titans to the criminals, but then contributes to the heroes’ defeat by confusing the powers of one super-villain trio with the other. Finally, the Titans are able to defeat both gangs by turning their powers against each other, but not before Robin and the Joker’s Daughter are captured by the mastermind behind the two villainous groups, Two-Face.
